                           HOLDING COMPANY STRUCTURE

         The Company is a holding company and its assets consist primarily of
investments in its subsidiaries and majority-owned partnerships. The Company's
rights and the rights of its creditors, including holders of Debt Securities,
to participate in the distribution of assets of any person in which the Company
owns an equity interest (including any subsidiary and majority-owned
partnerships) upon such person's liquidation or reorganization will be subject
to prior claims of such person's creditors, including trade creditors, except
to the extent that the Company may itself be a creditor with recognized claims
against such person (in which case the claims of the Company would still be
subject to the prior claims of any secured creditor or such person and of any
holder of indebtedness of such person that is senior to that held by the
Company). Accordingly, the holder of Debt Securities may be deemed to be
effectively subordinated to such claims.


                        DESCRIPTION OF DEBT SECURITIES

GENERAL

         The following description of the terms of the Debt Securities sets
forth certain general terms and provisions of the Debt Securities to which any
Prospectus Supplement may relate. The particular terms of any Debt Securities
and the extent, if any, to which such general provisions will not apply to such
Debt Securities will be described in the Prospectus Supplement relating to such
Debt Securities.

         The Debt Securities will be issued from time to time in series under
an Indenture to be entered into (the "Indenture"), between the Company and
Texas Commerce Bank National Association, as Trustee (the "Trustee"). The
statements set forth below are brief summaries of certain provisions contained
in the Indenture, which summaries do not purport to be complete and are
qualified in their entirety by reference to the Indenture, a copy of which is
an exhibit to the Registration Statement of which this Prospectus is a part.
Numerical references in parentheses below are to articles or sections of the
Indenture. Wherever defined terms are used but not defined herein, such terms
shall have the meanings assigned to them in the Indenture, it being intended
that such referenced articles and sections of the Indenture and such defined
terms shall be incorporated herein by reference.

         The Indenture does not limit the amount of Debt Securities which may
be issued thereunder and Debt Securities may be issued thereunder up to the
aggregate principal amount which may be authorized from time to time by the
Company.  Any such limit applicable to a particular series will be specified in
the Prospectus Supplement relating to that series.

         Reference is made to the Prospectus Supplement for the following terms
of each series of Debt Securities in respect to which this Prospectus is being
delivered: (i) the designation, date, aggregate principal amount, currency or
currency unit of payment and authorized denominations of such Debt Securities;
(ii) initial public offering price or prices of the Debt Securities and any
discounts or commissions paid to underwriters, dealers or agents in connection
therewith; (iii) the date or dates on which such Debt Securities will mature
(which may be fixed or extendible); (iv) the rate or rates (or manner of
calculation thereof), if any, per annum at which such Debt Securities will bear
interest; (v) the dates, if any, on which such interest will be payable; (vi)
the terms of any mandatory or optional redemption (including any sinking,
purchase or analogous fund) and any purchase at the option of holders
(including any sinking, purchase or analogous fund) and any purchase at the
option of holders; (vii) whether such Debt Securities are to be issued in the
form of Global Securities and, if so, the identity of the Depository with
respect to such Global Securities; and (viii) any other specific terms.

         Unless otherwise set forth in the Prospectus Supplement, interest on
outstanding Debt Securities will be paid to holders of record on the date which
is 15 days immediately prior to the date such interest is to be paid. Unless
otherwise specified in the Prospectus Supplement, Debt Securities will be
issued in fully registered form only and in denominations of $1,000 and
integral multiples thereof. Unless otherwise specified in the Prospectus
Supplement, the principal amount of the Debt Securities will be payable at the
corporate trust office of the Trustee in New York, New York. The Debt
Securities may be presented for transfer or exchange at such office unless
otherwise specified in the Prospectus Supplement, subject to the limitations
provided in the Indenture, without any service charge, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charges payable in connection therewith.  (Section 305)

RANKING

         Unless otherwise specified in a Prospectus Supplement for a particular
series of Debt Securities, all series of Debt Securities will be senior
indebtedness of the Company and will be direct, unsecured obligations of the
Company, ranking on a parity with all other unsecured and unsubordinated
indebtedness of the Company. The Company is a holding company and the Debt
Securities will be effectively subordinated to all existing and future
liabilities, including indebtedness, of the Company's subsidiaries. See
"Holding Company Structure."

purchase, redemption, defeasance, retirement, sinking fund payment, payment at

by virtue of acceleration of such Debt upon an event of default thereunder)
prior to the scheduled maturity or maturities of the Debt or Preferred Stock
being refinanced or refunded; and (ix) Debt not otherwise permitted to be
Incurred pursuant to clauses (i) through (viii) above, which, together with any

principal amount not in excess of the greater of $20 million or 10% of
Consolidated Stockholders' Equity.

         LIMITATION ON LIENS. The Company shall not, and shall not permit any
Subsidiary of the Company, to incur any Lien on property or assets of the
Company or such Subsidiary to secure Debt without making, or causing such
Subsidiary to make, effective provision for securing the Debt Securities (and,
if required by its governing instruments, any other Debt of the Company or of
such Subsidiary that is not subordinate to the Debt Securities) equally and
ratably with such Debt as to such property for so long as such Debt will be so
secured or, in the event such Debt is Debt of the Company which is subordinate
in right of payment to the Debt Securities, prior to such Debt as to such
property for so long as such Debt will be so secured.

         The foregoing restrictions will not apply to Liens existing at the
date of the Indenture or to: (i) Liens on inventories and accounts receivable
existing from time to time; (ii) Liens securing only the Debt Securities; (iii)
Liens in favor of the Company; (iv) Liens on property of a Person existing at
the time such Person is merged into or consolidated with the Company or any
Subsidiary of the Company or any Subsidiary of the Company merges into or
consolidates with such Person and not securing Debt Incurred in anticipation of
such transaction; (v) Liens on property existing at the time of acquisition
thereof; (vi) Liens to secure Debt Incurred for the purpose of financing all or
any part of the purchase price or the cost of construction or improvement (or
additions to improvements) of the property subject to such Liens; (vii) Liens
on property of the Company or any of its Subsidiaries in favor of the United
States of America or any state thereof, or any instrumentality of either, to
secure certain payments pursuant to any contract or statute; (viii) Liens
granted to any bank or other institution on the payments to be made by such
institution to the Company or a Subsidiary of the Company pursuant to any
interest rate swap or similar agreement or foreign currency hedge, exchange or
similar agreement designed to provide protection against fluctuations in
interest rates and currency exchange rates, respectively, provided that such
agreements are entered into in, or are incidental to, the ordinary course of
business or are entered into in connection with Debt permitted by the
provisions described under "Limitation on Subsidiary Debt" above, between the
Company or such Subsidiary and such institution; (ix) Liens to secure
industrial revenue or development bonds, not to exceed $5 million at any one
time outstanding; (x) mechanics', workmen's, materialmen's or similar Liens

refinancing or refundings), in whole or in part, of any Debt secured by Liens
referred to in the foregoing clauses (i) to (x) so long as such Lien does not
extend to any other property and the Debt so secured is not increased; (xii)
Liens incurred in the ordinary course of business that are not material to the
business or financial condition of the Company and its Subsidiaries taken as a
whole and which do not secure Debt in an aggregate principal amount in excess
of the greater of $20 million or 10% of Consolidated





                                       5
<PAGE>   7
Stockholders' Equity at any one time outstanding; and (xiii) any Liens securing
Debt owed by the Company to one or more Wholly Owned Subsidiaries of the
Company (but only if such Debt is held by such Wholly Owned Subsidiaries).

         LIMITATION ON SALE AND LEASEBACK TRANSACTIONS. The Company shall not,
and shall not permit any Subsidiary of the Company, to enter into any Sale and
Leaseback Transaction (except for a period not exceeding three years) unless
the Company or such Subsidiary would be entitled to incur a Lien to secure Debt
by reason of the provisions described in clauses (i) through (xiii) of the
second paragraph under the "Limitation on Liens" covenant in an amount equal to
the Attributable Value of such Sale and Leaseback Transaction without equally
and ratably securing the Debt Securities.

         LIMITATION ON MERGER, CONSOLIDATION AND CERTAIN SALES OF ASSETS. The
Indenture provides that the Company will not merge or consolidate with or into,
or convey, lease or transfer all or substantially all of its property to, any
Person unless (a) the successor is organized and existing under the laws of the
United States or any State or the District of Columbia, (b) the successor
expressly assumes by supplemental indenture all of the Company's obligations
under the Indenture and the Debt Securities issued under the Indenture on the
same terms and conditions and (c) immediately after giving effect to such
transaction, there is no default under the Indenture. In the event a successor
corporation assumes the obligations of the Company, such successor corporation
shall succeed to and be substituted for the Company under the Indenture and
under the Debt Securities and all obligations of the Company shall terminate.
(Article 8)

         Any additional covenants pertaining to a series of Debt Securities
will be set forth in a Prospectus Supplement relating to such series of Debt
Securities.

         LEVERAGED TRANSACTIONS AND CHANGES IN CONTROL. Other than the
Limitation on Subsidiary Debt, Limitation on Liens and Limitation on Sale and
Leaseback Transactions covenants described above, the Indenture and the Debt
Securities do not contain any covenants or other provisions designed to afford
holders of the Debt Securities protection in the event of a highly leveraged
transaction involving the Company. The Indenture does not contain provisions
requiring redemption of the Debt Securities by the Company, or adjustment to
any terms of the Debt Securities, upon any change in control of the Company.

CERTAIN DEFINITIONS

         For purposes of the Indenture, the following terms have the meanings
set forth below.

         "Attributable Value" means, as to any particular lease under which any

term thereof as determined in accordance with GAAP, discounted from the last
date of such initial term to the date of determination at a rate per annum
equal to the discount rate which would be applicable to a Capital Lease
Obligation with like term in accordance with GAAP. The net amount of rent
required to be paid under any such lease for any such period shall be the
aggregate amount of rent payable by the lessee with respect to such period
after excluding amounts required to be paid on account of insurance, taxes,
assessments, utility, operating and labor costs and similar charges. In the

rent shall be considered as required to be paid under such lease subsequent to
the first date upon which it may be so terminated. "Attributable Value" means,
as to a Capital Lease Obligation under which any Person is at the time liable

rent or other payment amounts under a lease of (or other Debt arrangements
conveying the right to use) real or personal property of such Person which is

stated maturity of such obligation shall be the date of the last payment of
rent or any other amount due under such lease or other Debt arrangements prior
to the first date upon which such lease may be terminated by the lessee without
payment of a penalty.

participation or other equivalents (however designated) of corporate stock of

reimbursement obligation of such Person with respect to letters of credit,
bankers' acceptances or similar facilities issued for the account of such

not overdue by more than 90 days or (y) which are being contested in good faith
by appropriate proceedings promptly instituted and diligently conducted and for
which a proper reserve or other appropriate provision, if any, as shall be
required in accordance with GAAP shall have been made), (v) every Capital Lease
Obligation of such Person, (vi) the maximum fixed redemption or repurchase
price of Redeemable Stock of such Person at the time of determination, (vii)
every payment obligation of such Person under interest rate swap or similar
agreements or foreign currency hedge, exchange or similar agreements at the
time of determination, (viii) every obligation to pay rent or other similar
amounts of such Person with respect to any Sale and Leaseback Transaction to

         "Lien" means, with respect to any property or assets, any mortgage or
deed of trust, pledge, hypothecation, assignment, deposit agreement, security

DEFEASANCE

         The Indenture provides that the Company, at its option, (a) will be
Discharged from any and all obligations in respect of any series of Debt
Securities (except in each case for certain obligations to register the
transfer or exchange of Debt Securities, replace stolen, lost or mutilated Debt
Securities, maintain paying agencies and hold moneys for payment in trust) or
(b) need not comply with the covenant described above under "Limitation on
Merger, Consolidation and Certain Sales of Assets" and any other restrictive
covenant described in a Prospectus Supplement relating to such series of Debt
Securities, and certain Events of Default (other than those arising out of the
failure to pay interest or principal on the Debt Securities of a particular
series and certain events of bankruptcy, insolvency and reorganization) will no
longer constitute Events of Default with respect to such series of Debt
Securities, in each case if the Company deposits with the applicable Trustee,
in trust, money or the equivalent in securities of the government which issued
the currency in which the Debt Securities are denominated or government
agencies backed by the full faith and credit of such government, or a
combination thereof, which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money in an
amount sufficient to pay all the principal (including any mandatory sinking
fund payments) of, and interest on, such series on the dates such payments are
due in accordance with the terms of such series. To exercise any such option,
the Company is required, among other things, to deliver to the Trustee an
Opinion of Counsel to the effect that (i) the deposit and related defeasance
would not cause the holders of such series to recognize income, gain or loss
for Federal income tax purposes and, in the case of a Discharge pursuant to
clause (a), accompanied by a ruling to such effect received from or published
by the United States Internal Revenue Service and (ii) the creation of the
defeasance trust will not violate the Investment Company Act of 1940. In
addition, the Company is required to deliver to the Trustee an Officers'
Certificate





                                       8
<PAGE>   10
stating that such deposit was not made by the Company with the intent of
preferring the holders over other creditors of the Company or with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others.  (Article 4)

EVENTS OF DEFAULT, NOTICE AND WAIVER

         The Indenture provides that, if an Event of Default specified therein
with respect to any series of Debt Securities issued thereunder shall have
happened and be continuing, either the Trustee thereunder or the holders of 25%
in aggregate principal amount of the outstanding Debt Securities of such series
(or 25% in aggregate principal amount of all outstanding Debt Securities under
the Indenture, in the case of certain Events of Default affecting all series of
Debt Securities under the Indenture) may declare the principal of all the Debt
Securities of such series to be due and payable. (Section 502)

         Events of Default in respect of any series are defined in the
Indenture as being: (i) default for 30 days in payment of any interest
installment with respect to such series; (ii) default in payment of principal
of, or premium, if any, on, or any sinking fund or analogous payment with
respect to, Debt Securities of such series when due at their stated maturity,
by declaration or acceleration, when called for redemption or otherwise; (iii)
default for 30 days after notice to the Company by the Trustee thereunder or by
holders of 25% in aggregate principal amount of the outstanding Debt Securities
of such series in the performance of any covenant in such Indenture with
respect to Debt Securities of such series; (iv) failure to pay when due, upon
final maturity or upon acceleration, the principal amount of any indebtedness
for money borrowed of the Company in excess of $5 million, if such indebtedness
is not discharged, or such acceleration annulled, within 30 days after written
notice; and (v) certain events of bankruptcy, insolvency and reorganization
with respect to the Company or any Significant Subsidiary. (Section 501 and
Form of the Senior Security)

         Any additions, deletions or other changes to the Events of Default
which will be applicable to a series of Debt Securities will be described in
the Prospectus Supplement relating to such series of Debt Securities.

         The Indenture provides that the Trustee thereunder will, within 90
days after the occurrence of a default with respect to the Debt Securities of
any series, give to the holders of the Debt Securities of such series notice of
all uncured and unwaived default known to it; provided that, except in the case
of default in the payment of principal of, premium, if any, or interest, if
any, on any of the Debt Securities of such series, the Trustee thereunder will
be protected in withholding such notice if it in good faith determines that the
withholding of such notice is in the interests of the holders of the Debt
Securities of such series. The term "default" for the purpose of this provision
means the happening of any of the Events of Default specified above, except
that any grace period or notice requirement is eliminated. (Section 602)

         The Indenture contains provisions entitling the Trustee, subject to
the duty of the Trustee during an Event of Default to act with the required
standard of care, to be indemnified by the holders of the Debt Securities
before proceeding to exercise any right or power under the Indenture at the
request of holders of the Debt Securities.  (Section 603)

         The Indenture provides that the holders of a majority in aggregate
principal amount of the outstanding Debt Securities of any series may direct
the time, method and place of conducting proceedings for remedies available to
the Trustee or exercising any trust or power conferred on the Trustee in
respect of such series. (Section 512)

         The Indenture includes a covenant that the Company will file annually
with the Trustee a certificate of no default or specifying any default that
exists. (Section 1004)

         In certain cases, the holders of a majority in principal amount of the
outstanding Debt Securities of any series may on behalf of the holders of all
Debt Securities of such series waive any past default or Event of Default with
respect to the Debt Securities of such series or compliance with certain
provisions of the Indenture, except, among other things, a default not
theretofore cured in payment of the principal of, premium, if any, or interest,
if any, on any of the Debt Securities of such series. (Sections 513 and 1009)

MODIFICATION OF THE INDENTURE

         The Company and the Trustee may, without the consent of the holders of
the Debt Securities, enter into indentures supplemental to the Indenture for,
among others, one or more of the following purposes: (i) to evidence the
succession of another Person to the Company, and the assumption by such
successor of the Company's obligations under the Indenture and the Debt
Securities of any series; (ii) to add covenants of the Company, or surrender
any rights of the Company, for the benefit of the holders of Securities of any
or all series; (iii) to cure any ambiguity, or correct any inconsistency in the
Indenture; (iv) to evidence and provide for the acceptance of any successor
Trustee with respect to one or more series of Securities or to facilitate the
administration of the trusts thereunder by one or more trustees in accordance
with the Indenture; (v) to establish the form or terms of any series of Debt
Securities; and (vi) to provide any additional Events of Default. (Section 901)





                                       9
<PAGE>   11
         The Indenture contains provisions permitting the Company and the
Trustee thereunder, with the consent of the holders of a majority in principal
amount of the outstanding Debt Securities of each series to be affected, to
execute supplemental indentures adding any provisions to or changing or
eliminating any of the provisions of the Indenture or modifying the rights of
the holders of the Debt Securities of such series to be affected, except that
no such supplemental indenture may, without the consent of the holders of
affected Debt Securities, among other things, change the fixed maturity of any
Debt Securities, or reduce the principal amount thereof, or reduce the rate or
extend the time of payment of interest thereon, or reduce the aforesaid
percentage of Debt Securities of any series the consent of the holders of which
is required for any such supplemental indenture. (Section 902)

BOOK-ENTRY SYSTEM

         The provisions set forth below in this section headed "Book-Entry
System" will apply to the Debt Securities of any series if the Prospectus
Supplement relating to such series so indicates.

         The Debt Securities of such series will be represented by one or more
global securities (collectively, a "Global Security") registered in the name of
a depositary (the "DTC") or a nominee of DTC identified in the Prospectus
Supplement relating to such series. Except as set forth below, a Global
Security may be transferred, in whole and not in part, only to DTC or another
nominee of DTC.

         Upon the issuance of a Global Security, DTC will credit, on its
book-entry registration and transfer system, the respective principal amounts
of the Debt Securities represented by such Global Security to the accounts of
institutions that have accounts with DTC or its nominee ("participants"). The
accounts to be credited will be designated by the underwriters, dealers or
agents. Ownership of beneficial interests in a Global Security will be limited
to participants or Persons that may hold interests through participants.
Ownership of interests in such Global Security will be shown on, and the
transfer of those ownership interests will be effected only through, records
maintained by DTC (with respect to participants' interest) and such
participants (with respect to the owners of beneficial interests in such Global
Security). The laws of some jurisdictions may require that certain purchasers
of securities take physical delivery of such securities in definitive form.
Such limits and laws may impair the ability to transfer beneficial interests in
a Global Security.

         So long as DTC, or its nominee, is the registered holder and owner of
such Global Security, DTC or such nominee, as the case may be, will be
considered the sole owner and holder of the related Debt Securities for all
purposes of such Debt Securities and for all purposes under the Indenture.
Except as set forth below, owners of beneficial interests in a Global Security
will not be entitled to have Debt Securities represented by such Global
Security registered in their names, will not receive or be entitled to receive
physical delivery of Debt Securities in definitive form and will not be
considered to be the owners or holders of any Debt Securities under the
Indenture or such Global Security.

         Accordingly, each Person owning a beneficial interest in a Global
Security must rely on the procedures of DTC and, if such Person is not a
participant, on the procedures of the participant through which such Person
owns its interest, to exercise any rights of a holder of Debt Securities under
the Indenture or such action which DTC, as the holder of a Global Security, is
entitled to take under the Indenture or such Global Security. The Indenture
permits DTC to authorize participants, as its agents, to take any action which
DTC, as the holder of a Global Security, is entitled to take under the
Indenture or such Global Security. The Company understands that under existing
industry practice, in the event the Company requests any action of holders of
Debt Securities or an owner of a beneficial interest in a Global Security
desires to take any action that DTC, as the holder of such Global Security is
entitled to take, DTC would authorize the participants to take such action, and
that the participants would authorize beneficial owners owning through such
participants to take such action or would otherwise act upon the instructions
of beneficial owners owning through them.

         Payment of principal of and premium, if any, and interest, if any, on
Debt Securities represented by a Global Security will be made to DTC or its
nominee, as the case may be, as the registered owner and holder of such Global
Security.

         Upon receipt of any payment of principal, premium, if any, or
interest, if any, in respect of a Global Security, DTC will credit immediately
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Security
as shown on the records of DTC. Payments by participants to owners of
beneficial interests in a Global Security held through such participants will
be governed by standing instructions and customary practices, as is the case
with securities held for the accounts of customers in bearer form or registered
in "street name," and will be the responsibility of such participants. The
Company will not have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in a Global Security for any Debt Securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests or for any other aspect of the relationship between DTC and its
participants or the relationship between such participants and the owners of
beneficial interests in such Global Security owning through such participants.





                                       10
<PAGE>   12
         Unless and until it is exchanged in whole or in part for Debt
Securities in definitive form, a Global Security may not be transferred except
as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another
nominee of DTC.

         Debt Securities represented by a Global Security are exchangeable for
Debt Securities in definitive form of like tenor as such Global Security in
denominations of $1,000 and in any greater amount that is an integral multiple
thereof if (i) DTC notifies the Company that it is unwilling or unable to
continue as DTC for such Global Security or if at any time DTC ceases to be a
clearing agency registered under the Exchange Act, (ii) the Company in its
discretion at any time determines not to have all of the Debt Securities
represented by a Global Security and notifies the Trustee thereof, or (iii) an
Event of Default has occurred and is continuing with respect to the Debt
Securities. Any Debt Security that is exchangeable pursuant to the preceding
sentence is exchangeable for Debt Securities issuable in authorized
denominations and registered in such names as DTC shall direct. Subject to the
foregoing, a Global Security is not exchangeable, except for a Global Security
or Global Securities of the same aggregate denominations to be registered in
the name of DTC or its nominee.

SAME-DAY SETTLEMENT AND PAYMENT

         Settlement by the purchasers of the Debt Securities will be made in
immediately available funds. All payments by the Company to DTC of principal
and interest will be made in immediately available funds.

         The Debt Securities will trade in DTC's Same-Day Funds Settlement
System until maturity, and therefore DTC will require secondary trading
activity in the Debt Securities to be settled in immediately available funds.
No assurance can be given as to the effect, if any, of settlement in
immediately available funds on trading activity in the Debt Securities.

REGARDING THE TRUSTEE

         Texas Commerce Bank National Association is the managing agent for and
a lender under one of the Company's bank credit facilities, dated as of July
21, 1995, as amended, whereunder the Texas Commerce Bank National Association
and eight other domestic banks have agreed to lend up to $200 million to the
Company at any time and from time to time through June 30, 2002. Texas Commerce
Bank National Association has received and will in the future receive fees and
compensation in connection with those and other transactions.

GOVERNING LAW

         The Indenture and the Debt Securities will be governed by, and
construed in accordance with, the laws of the State of New York.


                              PLAN OF DISTRIBUTION

         The Company may sell the Debt Securities to or through underwriters,
dealers or agents or directly to other purchasers. The Prospectus Supplement
with respect to the Debt Securities offered thereby will describe the terms of
the Offering of such Debt Securities and the method of distribution of the Debt
Securities offered thereby and identify any firms acting as underwriters,
dealers or agents in connection therewith.

         The Debt Securities may be distributed from time to time in one or
more transactions at a fixed price or prices (which may be changed) or at
prices determined as specified in the Prospectus Supplement. In connection with
the sale of the Debt Securities underwriters, dealers or agents may be deemed
to have received compensation from the Company in the form of underwriting
discounts or commissions and may also receive commissions from purchasers for
whom they may act as agent. Certain of the underwriters, dealers or agents who
participate in the distribution of the Debt Securities may engage in other
transactions with, and perform other services for, the Company in the ordinary
course of business.

         Any underwriting compensation paid by the Company to underwriters or
agents in connection with the Offering of the Debt Securities, and any
discounts, concessions or commissions allowed by underwriters to dealers, are
set forth in the Prospectus Supplement. Underwriters, dealers and agents
participating in the distribution of the Debt Securities may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on the resale of the Debt Securities may be deemed to be
underwriting discounts and commissions under the Securities Act.  Underwriters
and their controlling persons, dealers and agents may be entitled, under
agreements entered into with the Company, to indemnification against, and
contribution toward, certain civil liabilities, including liabilities under the
Securities Act.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Company is a Texas corporation and the Texas Business Corporation
Act ("TBCA") empowers a corporation organized thereunder to indemnify its
directors and officers or former directors and officers and to purchase
insurance with respect to liability arising out of their capacity or status as
directors and officers.

         Reference is made to Article IX and Article VII, Section 8 of the
Company's Articles of Incorporation and Bylaws, respectively, which provide for
indemnification of officers and directors except as to certain circumstances
and except as provided by applicable law.

         Additionally, Article XIII of the Company's Articles of Incorporation
limits the liability of directors of the Company to the Company or its
stockholders (in their capacity as directors but not in their capacity as
officers) to the fullest extent permitted by the TBCA. The effect of such
Article XIII (based on the TBCA as of the date of this Prospectus) is that the
directors of the Company will not be personally liable for monetary damages for
breach of a director's fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for a transaction
from which a director received an improper benefit whether or not the benefit
resulted from an action taken within the scope of the director's office, or
(iv) for an act related to an unlawful stock repurchase or payment of a
dividend.

         Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
the Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Commission, such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

         The Company also carries directors' and officers' liability insurance.

ITEM 17. UNDERTAKINGS.

         (a) The undersigned Registrant 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;

                          (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
                 Statement. Notwithstanding the foregoing, any increase or
                 decrease 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;

         Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the Registration Statement.

                 (2) That, for the purpose of determining any liability under
         the Securities Act, 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.





                                      II-2
<PAGE>   16
                 (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) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
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.

         (c) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement 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.

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

         (e) For purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

         (f) For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offers therein, and the Offering of such securities at that time shall be
deemed to be the initial bona fide Offering thereof.

To the Representatives
named in Schedule I
hereto of the Under-

Schedule II hereto


Ladies and Gentlemen:

              TCA Cable TV, Inc., a Texas corporation (the "Company"), proposes
to sell to the underwriters named in Schedule II hereto (the "Underwriters"),
for whom you (the "Representatives") are acting as representatives, the
principal amount of its securities identified in Schedule I hereto (the
"Securities"), to be issued under an indenture (the "Indenture") dated as of
__________, 199_, between the Company and ____________, as trustee (the
"Trustee").  If the firm or firms listed in Schedule II hereto include only the
firm or firms listed in Schedule I hereto, then the terms "Underwriters" and
"Representatives", as used herein, shall each be deemed to refer to such firm
or firms.

              1.  Representations and Warranties.  The Company represents and
warrants to, and agrees with, each Underwriter as set forth below in this
Section 1.  Certain terms used in this Section 1 are defined in paragraph (c)
hereof.

              (a)  If the offering of the Securities is a Delayed Offering (as
specified in Schedule I hereto), paragraph (i) below is applicable and, if the
offering of the Securities is a Non-Delayed Offering (as so specified),
paragraph (ii) below is applicable.

                     (i)  The Company meets the requirements for the use of
              Form S-3 under the Securities Act of 1933 (the "Act") and has
              filed with the Securities and Exchange Commission (the
              "Commission") a registration statement (the file number of which
              is set forth in Schedule I hereto) on such Form, including a
              basic prospectus, for the registration
<PAGE>   2
                                                                               2




              under the Act of the offering and sale of the Securities.  The
              Company may have filed one or more amendments thereto, and may
              have used a Preliminary Final Prospectus, each of which has
              previously been furnished to you.  Such registration statement,
              as so amended, has become effective.  The offering of the
              Securities is a Delayed Offering and, although the Basic
              Prospectus may not include all the information with respect to
              the Securities and the offering thereof required by the Act and
              the rules thereunder to be included in the Final Prospectus, the
              Basic Prospectus includes all such information required by the
              Act and the rules thereunder to be included therein as of the
              Effective Date.  The Company will next file with the Commission
              pursuant to Rules 415 and 424(b)(2) or (5) a final supplement to
              the form of prospectus included in such registration statement
              relating to the Securities and the offering thereof.  As filed,
              such final prospectus supplement shall include all required
              information with respect to the Securities and the offering
              thereof and, except to the extent the Representatives shall agree
              in writing to a modification, shall be in all substantive
              respects in the form furnished to you prior to the Execution Time
              or, to the extent not completed at the Execution Time, shall
              contain only such specific additional information and other
              changes (beyond that contained in the Basic Prospectus and any
              Preliminary Final Prospectus) as the Company has advised you,
              prior to the Execution Time, will be included or made therein.
              The Company agrees that it will not, without your agreement, file
              a Rule 462(b) Registration Statement.

                     (ii)  The Company meets the requirements for the use of
              Form S-3 under the Act and has filed with the Commission a
              registration statement (the file number of which is set forth in
              Schedule I hereto) on such Form, including a basic prospectus,
              for registration under the Act of the offering and sale of the
              Securities.  The Company may have filed one or more amendments
              thereto, including a Preliminary Final Prospectus, each of which
              has previously been furnished to you.  The

              Company will next file with the Commission either (x) a final
              prospectus supplement relating to the Securities in accordance
              with Rules 430A and 424(b)(1) or (4), or (y) prior to the
              effectiveness of such registration statement, an amendment to

              has included in such registration statement, as amended at the
              Effective Date, all information (other than Rule 430A
              Information) required by the Act and the rules thereunder to be
              included in the Final Prospectus with respect to the Securities
              and the offering thereof.  As filed, such final prospectus
              supplement or such amendment and form of final prospectus
              supplement shall contain all Rule 430A Information, together with
              all other such required information, with respect to the
              Securities and the offering thereof and, except to the extent the
              Representatives shall agree in writing to a modification, shall
              be in all substantive respects in the form furnished to you prior
              to the Execution Time or, to the extent not completed at the
              Execution Time, shall contain only such specific additional
              information and other changes (beyond that contained in the Basic
              Prospectus and any Preliminary Final Prospectus) as the Company
              has advised you, prior to the Execution Time, will be included or
              made therein.

              (b)  On the Effective Date, the Registration Statement did or
       will, and when the Final Prospectus is first filed (if required) in
       accordance with Rule 424(b) and on the Closing Date, the Final
       Prospectus (and any supplements thereto) will, comply in all material
       respects with the applicable requirements of the Act, the Securities
       Exchange Act of 1934 (the "Exchange Act") and the Trust Indenture Act of
       1939 (the "Trust Indenture Act") and the respective rules thereunder; on
       the Effective Date, the Registration Statement did not or will not
       contain any untrue statement of a material fact or omit to state any
       material fact required to be stated therein or necessary in order to
       make the statements therein not misleading; on the Effective Date and on
       the Closing Date the Indenture did or will comply in all material
       respects with the requirements of the Trust Indenture

       Act and the rules thereunder; and, on the Effective Date, the Final
       Prospectus, if not filed pursuant to Rule 424(b), did not or will not,
       and on the date of any filing pursuant to Rule 424(b) and on the Closing
       Date, the Final Prospectus (together with any supplement thereto) will
       not, include any untrue statement of a material fact or omit to state a
       material fact necessary in order to make the statements therein, in the
       light of the circumstances under which they were made, not misleading;
       provided, however, that the Company makes no representations or
       warranties as to (i) that part of the Registration Statement which shall
       constitute the Statement of Eligibility and Qualification (Form T-1)
       under the Trust Indenture Act of the Trustee or (ii) the information
       contained in or omitted from the Registration Statement or the Final

              (c)  The terms which follow, when used in this Agreement, shall
       have the meanings indicated.  The term the "Effective Date" shall mean

       exhibits and financial statements, as amended at the Execution Time (or,
       if not effective at the Execution Time, in the form in which it shall
       become effective) and, in the event any post-effective amendment thereto
       or any Rule 462(b) Registration Statement becomes effective prior to the
       Closing Date (as hereinafter defined), shall also mean such registration
       statement as so amended or such Rule 462(b) Registration Statement, as
       the case may be.  Such term shall include any Rule 430A Information
       deemed to be included therein at the Effective Date as provided by Rule

       the effective date thereof.  A "Delayed Offering" shall mean an offering
       of securities pursuant to Rule 415 which does not commence promptly

       that only information required pursuant to Rule 415 need be included in
       such registration statement at the effective date thereof with respect
       to the securities so offered.  Whether the offering of the Securities is
       a Non-Delayed Offering or a Delayed Offering shall be set forth in
       Schedule I hereto.

              (d)  The Company and each of its subsidiaries have been duly
       incorporated and are validly existing as corporations in good standing
       under the laws of their respective jurisdictions of incorporation, are
       duly qualified to do business and are in good standing as foreign
       corporations in each jurisdiction in which their respective ownership or
       lease of property or the conduct of their respective businesses requires
       such qualification, and have all power and authority necessary to own or
       hold their respective properties and to conduct the businesses in which
       they are engaged, except where the failure to so qualify or have such
       power or authority would not have, singularly or in the aggregate, a
       material adverse effect on the condition (financial or otherwise),
       results of operations, business or prospects of the Company and its
       subsidiaries taken as a whole.

              (e)  The Company has an authorized capitalization as set forth in

              (f)  The execution, delivery and performance of this Agreement,

       the transactions contemplated hereby and thereby will not conflict with
       or result in a breach or violation of any of the terms

                                                                               7




       or provisions of, or constitute a default under, any indenture,
       mortgage, deed of trust, loan agreement or other agreement or instrument
       to which the Company or any of its subsidiaries is a party or by which
       the Company or any of its subsidiaries is bound or to which any of the
       property or assets of the Company or any of its subsidiaries is subject,
       nor will such actions result in any violation of the provisions of the
       charter or by-laws of the Company or any of its subsidiaries or any
       statute or any order, rule or regulation of any court or governmental
       agency or body having jurisdiction over the Company or any of its
       subsidiaries or any of their properties or assets; and except for the
       registration of the Securities under the Act, the qualification of the
       Indenture under the Trust Indenture Act and such consents, approvals,
       authorizations, registrations or qualifications as may be required under
       the Exchange Act and applicable state securities laws in connection with
       the purchase and distribution of the Securities by the Underwriters, no
       consent, approval, authorization or order of, or filing or registration
       with, any such court or governmental agency or body is required for the
       execution, delivery and performance of this Agreement, the Indenture or
       the Securities by the Company and the consummation of the transactions
       contemplated hereby and thereby.

              (g)  The financial statements (including the related notes and
       supporting schedules) filed as part of the Registration Statement or
       included or incorporated by reference in the Prospectus present fairly
       the financial condition and results of operations of the entities
       purported to be shown thereby, at the dates and for the periods
       indicated, and have been prepared in conformity with generally accepted
       accounting principles applied on a consistent basis throughout the
       periods involved.

              (h)  There are no contracts or other documents which are required
       to be described in the Prospectus or filed as exhibits to the
       Registration Statement by the Act or by the Rules and Regulations and
       which have not been so described or filed.

              (i)  There are no legal or governmental proceedings pending to
       which the Company or any of its subsidiaries is a party or of which any
       property or





<PAGE>   8
                                                                               8




       assets of the Company or any of its subsidiaries is the subject which,
       singularly or in the aggregate, if determined adversely to the Company
       or any of its subsidiaries, are reasonably likely to have a material
       adverse effect on the condition (financial or otherwise), results of
       operations, business or prospects of the Company and its subsidiaries
       taken as a whole; and to the best of the Company's knowledge, no such
       proceedings are threatened or contemplated by governmental authorities
       or threatened by others.

              (j)  Neither the Company nor any of its subsidiaries (i) is in
       violation of its charter or by-laws, (ii) is in default in any material
       respect, and no event has occurred which, with notice or lapse of time
       or both, would constitute such a default, in the due performance or
       observance of any term, covenant or condition contained in any material
       indenture, mortgage, deed of trust, loan agreement or other agreement or
       instrument to which it is a party or by which it is bound or to which
       any of its property or assets is subject or (iii) is in violation in any
       respect of any law, ordinance, governmental rule, regulation or court
       decree to which it or its property or assets may be subject, except any
       violation or default that would not have a material adverse effect on
       the condition (financial or otherwise), results of operations, business
       or prospects of the Company and its subsidiaries taken as a whole.

              (k)  The Company and each of its subsidiaries possess all
       material licenses, certificates, authorizations and permits issued by,
       and have made all declarations and filings with, the appropriate state,
       federal or foreign regulatory agencies or bodies which are necessary or
       desirable for the ownership of their respective properties or the
       conduct of their respective businesses as described in the Prospectus,
       except where the failure to possess or make the same would not have,
       singularly or in the aggregate, a material adverse effect on the
       condition (financial or otherwise), results of operations, business or
       prospects of the Company and its subsidiaries taken as a whole, and the
       Company has not received notification of any revocation or modification
       of any such license, authorization or permit and has no reason to
       believe

                                                                               9




       that any such license, certificate, authorization or permit will not be
       renewed.

              (l)  Except as disclosed in the Registration Statement and the
       Prospectus, the Company (i) does not have any material lending or other
       relationship with any bank or lending affiliate of any of the
       Underwriters, and (ii) does not intend to use any of the proceeds from
       the sale of the Securities hereunder to repay any outstanding debt owed
       to any affiliate of any of the Underwriters.

              (m)  The Company has full right, power and authority to execute
       and deliver this Agreement, the Indenture and the Securities and to
       perform its obligations hereunder and thereunder; and all corporate
       action required to be taken for the due and proper authorization,
       execution and delivery of this Agreement, the Indenture and the
       Securities and the consummation of the transactions contemplated by this
       Agreement and the Indenture have been duly and validly taken.

              (n)  The Indenture, when duly executed by the proper officers of
       the Company and delivered by the Company, will constitute a valid and
       binding agreement of the Company enforceable against the Company in
       accordance with its terms, subject to the effects of bankruptcy,
       insolvency, fraudulent conveyance, reorganization, moratorium and other
       similar laws relating to or affecting creditors' rights generally,
       general equitable principles (whether considered in a proceeding in
       equity or at law) and an implied covenant of good faith and fair
       dealing; and the Securities, when duly executed, authenticated, issued
       and delivered as provided in the Indenture, will be duly and validly
       issued and outstanding and will constitute valid and binding obligations
       of the Company entitled to the benefits of the Indenture and enforceable
       in accordance with their terms, subject to the effects of bankruptcy,
       insolvency, fraudulent conveyance, reorganization, moratorium and other
       similar laws relating to or affecting creditors' rights generally,
       general equitable principles (whether considered in a proceeding in
       equity or at law) and an implied covenant of good faith and fair
       dealing; and the Indenture and

       the Securities conform to the descriptions thereof contained in the
       Prospectus.

              (o)  There are no persons with registration or other similar
       rights either to have any securities registered pursuant to the
       Registration Statement or to have any securities otherwise registered by
       the Company under the Act in connection with or as a result of the
       execution, delivery and performance of this Agreement.

              (p)  Neither the Company nor any of its subsidiaries is an
       "investment company" within the meaning of the Investment Company Act of
       1940, as amended (the "Investment Company Act"), and the rules and
       regulations of the Commission thereunder.

              Any certificate signed by any officer of the Company and
delivered to the Representatives or counsel for the Underwriters in connection
with the offering of the Securities shall be deemed a representation and
warranty by the Company, as to matters covered thereby, to each Underwriter.

              2.  Purchase and Sale.  Subject to the terms and conditions and
in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from the Company, at the purchase price
set forth in Schedule I hereto the principal amount of the Securities set forth
opposite such Underwriter's name in Schedule II hereto, except that, if
Schedule I hereto provides for the sale of Securities pursuant to delayed
delivery arrangements, the respective principal amounts of Securities to be
purchased by the Underwriters shall be as set forth in Schedule II hereto less
the respective amounts of Contract Securities determined as provided below.
Securities to be purchased by the Underwriters are herein sometimes called the
"Underwriters' Securities" and Securities to be purchased pursuant to Delayed
Delivery Contracts as hereinafter provided are herein called "Contract
Securities".

              If so provided in Schedule I hereto, the Underwriters are
authorized to solicit offers to purchase Securities from the Company pursuant
to delayed delivery contracts ("Delayed Delivery Contracts"), substantially in
the form of Schedule III hereto but with such changes therein as





<PAGE>   11
                                                                              11




the Company may authorize or approve.  The Underwriters will endeavor to make
such arrangements and, as compensation therefor, the Company will pay to the
Representatives, for the account of the Underwriters, on the Closing Date, the
percentage set forth in Schedule I hereto of the principal amount of the
Securities for which Delayed Delivery Contracts are made.  Delayed Delivery
Contracts are to be with institutional investors, including commercial and
savings banks, insurance companies, pension funds, investment companies and
educational and charitable institutions.  The Company will enter into Delayed
Delivery Contracts in all cases where sales of Contract Securities arranged by
the Underwriters have been approved by the Company but, except as the Company
may otherwise agree, each such Delayed Delivery Contract must be for not less
than the minimum principal amount set forth in Schedule I hereto and the
aggregate principal amount of Contract Securities may not exceed the maximum
aggregate principal amount set forth in Schedule I hereto.  The Underwriters
will not have any responsibility in respect of the validity or performance of
Delayed Delivery Contracts.  The principal amount of Securities to be purchased
by each Underwriter as set forth in Schedule II hereto shall be reduced by an
amount which shall bear the same proportion to the total principal amount of
Contract Securities as the principal amount of Securities set forth opposite
the name of such Underwriter bears to the aggregate principal amount set forth
in Schedule II hereto, except to the extent that you determine that such
reduction shall be otherwise than in such proportion and so advise the Company
in writing; provided, however, that the total principal amount of Securities to
be purchased by all Underwriters shall be the aggregate principal amount set
forth in Schedule II hereto less the aggregate principal amount of Contract
Securities.

              3.  Delivery and Payment.  Delivery of and payment for the
Underwriters' Securities shall be made on the date and at the time specified in
Schedule I hereto (or such later date not later than five business days after
such specified date as the Representatives shall designate), which date and
time may be postponed by agreement between the Representatives and the Company
or as provided in Section 8 hereof (such date and time of delivery and payment
for the Underwriters' Securities being herein called the "Closing Date").
Delivery of the Underwriters' Securities shall be made to the Representatives
for the respective accounts of the several Underwriters against payment by the 





<PAGE>   12
                                                                              12




several Underwriters through the Representatives of the purchase price thereof
to or upon the order of the Company by wire transfer payable in same-day funds. 
Delivery of, and payment for, the Underwriters' Securities shall be made
through the facilities of The Depository Trust Company.

              4.  Agreements.  The Company agrees with the several Underwriters
that:

              (a)  The Company will use its best efforts to cause the
       Registration Statement, if not effective at the Execution Time, and any
       amendment thereto, to become effective.  Prior to the termination of the
       offering of the Securities, the Company will not file any amendment of
       the Registration Statement or supplement (including the Final Prospectus
       or any Preliminary Final Prospectus) to the Basic Prospectus or any Rule
       462(b) Registration Statement unless the Company has furnished you a
       copy for your review prior to filing and will not file any such proposed
       amendment or supplement to which you reasonably object.  Subject to the
       foregoing sentence, the Company will cause the Final Prospectus,
       properly completed, and any supplement thereto to be filed with the
       Commission pursuant to the applicable paragraph of Rule 424(b) within
       the time period prescribed and will provide evidence satisfactory to the
       Representatives of such timely filing.  The Company will promptly advise
       the Representatives (i) when the Registration Statement, if not
       effective at the Execution Time, and any amendment thereto, shall have
       become effective, (ii) when the Final Prospectus, and any supplement
       thereto, shall have been filed with the Commission pursuant to Rule
       424(b) or when any Rule 462(b) Registration Statement shall have been
       filed with the Commission, (iii) when, prior to termination of the
       offering of the Securities, any amendment to the Registration Statement
       shall have been filed or become effective, (iv) of any request by the
       Commission for any amendment of the Registration Statement, or any Rule
       462(b) Registration Statement, or supplement to the Final Prospectus or
       for any additional information, (v) of the issuance by the Commission of
       any stop order suspending the effectiveness of the Registration
       Statement or the institution or threatening of any proceeding for that
       purpose and (vi) of the receipt by the Company of any notification with
       respect to the suspension of the qualification of





<PAGE>   13
                                                                              13




       the Securities for sale in any jurisdiction or the initiation or
       threatening of any proceeding for such purpose.  The Company will use
       its best efforts to prevent the issuance of any such stop order and, if
       issued, to obtain as soon as possible the withdrawal thereof.  The
       Company shall file promptly all reports and any definitive proxy or
       information statements required to be filed by the Company with the
       Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange
       Act subsequent to the date of the Prospectus and for so long as the
       delivery of a prospectus is required in connection with the offering or
       sale of the Securities.

              (b)  If, at any time when a prospectus relating to the Securities
       is required to be delivered under the Act, any event occurs as a result
       of which the Final Prospectus as then supplemented would include any
       untrue statement of a material fact or omit to state any material fact
       necessary to make the statements therein in the light of the
       circumstances under which they were made not misleading, or if it shall
       be necessary to amend the Registration Statement or supplement the Final
       Prospectus to comply with the Act or the Exchange Act or the respective
       rules thereunder, the Company promptly will (i) prepare and file with
       the Commission, subject to the second sentence of paragraph (a) of this
       Section 4, an amendment or supplement which will correct such statement
       or omission or effect such compliance and (ii) supply any supplemented
       Prospectus to you in such quantities as you may reasonably request.

              (c)  As soon as practicable, the Company will make generally
       available to its security holders and to the Representatives an earnings
       statement or statements of the Company and its subsidiaries which will
       satisfy the provisions of Section 11(a) of the Act and Rule 158 under
       the Act.

              (d)  The Company will furnish to the Representatives and counsel
       for the Underwriters, without charge, signed copies of the Registration
       Statement (including exhibits thereto) and, so long as delivery of a
       prospectus by an Underwriter or dealer may be required by the Act, as
       many copies of any Preliminary Final Prospectus and the Final Prospectus





<PAGE>   14
                                                                              14




       and any supplement thereto as the Representatives may reasonably
       request.  The Company will pay the expenses of printing or other
       production of all documents relating to the offering.

              (e)  The Company will arrange, if necessary, for the
       qualification of the Securities for sale under the laws of such
       jurisdictions as the Representatives may designate, will maintain such
       qualifications in effect so long as required for the distribution of the
       Securities, will arrange for the determination of the legality of the
       Securities for purchase by institutional investors and will pay any fee
       of the National Association of Securities Dealers, Inc., in connection
       with its review of the offering.

              (f)  Until the business date set forth on Schedule I hereto, the
       Company will not, without the consent of the Representatives, offer,
       sell or contract to sell, or otherwise dispose of (or enter into any
       transaction which is designed to, or could be expected to, result in the
       disposition by any person of) directly or indirectly, or announce the
       offering of, any debt securities issued or guaranteed by the Company
       (other than the Securities).

              5.  Conditions to the Obligations of the Underwriters.  The
obligations of the Underwriters to purchase the Underwriters' Securities shall
be subject to the accuracy of the representations and warranties on the part of
the Company contained herein as of the Execution Time and the Closing Date, to
the accuracy of the statements of the Company made in any certificates pursuant
to the provisions hereof, to the performance by the Company of its obligations
hereunder and to the following additional conditions:

              (a)  If the Registration Statement has not become effective prior
       to the Execution Time, unless the Representatives agree in writing to a
       later time, the Registration Statement will become effective not later
       than (i) 6:00 p.m. New York City time, on the date of determination of
       the public offering price, if such determination occurred at or prior to
       3:00 p.m. New York City time on such date or (ii) 12:00 Noon on the
       business day following the day on which the public offering price was
       determined, if such determination





<PAGE>   15
                                                                              15




       occurred after 3:00 p.m. New York City time on such date; if filing of
       the Final Prospectus, or any supplement thereto, is required pursuant to
       Rule 424(b), the Final Prospectus, and any such supplement, shall have
       been filed in the manner and within the time period required by Rule
       424(b); and no stop order suspending the effectiveness of the
       Registration Statement shall have been issued and no proceedings for
       that purpose shall have been instituted or threatened.

              (b)  The Company shall have furnished to the Representatives the
       opinion of Jackson & Walker, L.L.P., counsel for the Company, dated the
       Closing Date, to the effect that:

                     (i) each of the Company, _________ and ______________
              [list material subsidiaries] (individually a "Subsidiary" and
              collectively the "Subsidiaries") has been duly incorporated or
              formed and is validly existing as a corporation in good standing
              under the laws of the jurisdiction in which it is chartered or
              organized or as a partnership under the laws of the jurisdiction
              in which it is formed, with full power and authority to own its
              properties and conduct its business as described in the Final
              Prospectus, and is duly qualified to do business as a foreign
              corporation or partnership and is in good standing, or is duly
              qualified to do business as a foreign partnership, in each case
              under the laws of each jurisdiction which requires such
              qualification wherein it owns or leases material properties or
              conducts material business;

                     (ii) all the outstanding shares of capital stock of each
              Subsidiary have been duly and validly authorized and issued and
              are fully paid and nonassessable, and, except as otherwise set
              forth in the Final Prospectus, all outstanding shares of capital
              stock of the Subsidiaries are owned by the Company either
              directly or through wholly owned subsidiaries free and clear of
              any perfected security interest and, to the knowledge of such
              counsel, after due inquiry, any other security interests, claims,
              liens or encumbrances;





<PAGE>   16
                                                                              16




                     (iii)  the Company's authorized equity capitalization is
              as set forth in the Final Prospectus; [and] the Securities
              conform to the description thereof contained in the Final
              Prospectus; and, if the Securities are to be listed on any
              securities exchange, authorization therefor has been given,
              subject to official notice of issuance and evidence of
              satisfactory distribution, or the Company has filed a preliminary
              listing application and all required supporting documents with
              respect to the Securities with such securities exchange and such
              counsel has no reason to believe that the Securities will not be
              authorized for listing, subject to official notice of issuance
              and evidence of satisfactory distribution;

                     (iv)  the Indenture has been duly authorized, executed and
              delivered, has been duly qualified under the Trust Indenture Act,
              and constitutes a legal, valid and binding instrument enforceable
              against the Company in accordance with its terms (subject, as to
              enforcement of remedies, to applicable bankruptcy,
              reorganization, insolvency, moratorium or other laws affecting
              creditors' rights generally from time to time in effect); and the
              Securities have been duly authorized and, when executed and
              authenticated in accordance with the provisions of the Indenture
              and delivered to and paid for by the Underwriters pursuant to
              this Agreement, in the case of the Underwriters' Securities, or
              by the purchasers thereof pursuant to Delayed Delivery Contracts,
              in the case of any Contract Securities, will constitute legal,
              valid and binding obligations of the Company entitled to the
              benefits of the Indenture;

                     (v)  to the knowledge of such counsel, there is no pending
              or threatened action, suit or proceeding before any court or
              governmental agency, authority or body or any arbitrator
              involving the Company or any of its subsidiaries of a character
              required to be disclosed in the Registration Statement which is
              not adequately disclosed in the Final Prospectus, and there is no
              franchise, contract or other document of a character required to
              be described in the Registration





<PAGE>   17
                                                                              17




              Statement or Final Prospectus, or to be filed as an exhibit,
              which is not described or filed as required; and the statements
              included or incorporated in the Final Prospectus describing any
              legal proceedings or material contracts or agreements relating to
              the Company fairly summarize such matters;

                     (vi)  the Registration Statement has become effective
              under the Act; any required filing of the Basic Prospectus, any
              Preliminary Final Prospectus and the Final Prospectus, and any
              supplements thereto, pursuant to Rule 424(b) has been made in the
              manner and within the time period required by Rule 424(b); to the
              best knowledge of such counsel, no stop order suspending the
              effectiveness of the Registration Statement has been issued, no
              proceedings for that purpose have been instituted or threatened
              and the Registration Statement and the Final Prospectus (other
              than the financial statements and other financial and statistical
              information contained therein as to which such counsel need
              express no opinion) comply as to form in all material respects
              with the applicable requirements of the Act, the Exchange Act and
              the Trust Indenture Act and the respective rules thereunder; and
              such counsel has no reason to believe that at the Effective Date
              the Registration Statement contained any untrue statement of a
              material fact or omitted to state any material fact required to
              be stated therein or necessary to make the statements therein not
              misleading or that the Final Prospectus as of its date or the
              date of such opinion includes any untrue statement of a material
              fact or omits to state a material fact necessary to make the
              statements therein, in the light of the circumstances under which
              they were made, not misleading;

                     (vii)  this Agreement and any Delayed Delivery Contracts
              have been duly authorized, executed and delivered by the Company;

                     (viii)  no consent, approval, authorization or order of
              any court or governmental agency or body is required for the
              execution, delivery and performance of this Agreement, the
              Indenture and





<PAGE>   18
                                                                              18




              of the Securities or for the consummation of the transactions
              contemplated herein or in any Delayed Delivery Contracts, except
              such as have been obtained under the Act and such as may be
              required under the blue sky laws of any jurisdiction in
              connection with the purchase and distribution of the Securities
              by the Underwriters and such other approvals (specified in such
              opinion) as have been obtained;

                     (ix)  neither the execution and delivery of this
              Agreement, the Indenture, the issue and sale of the Securities,
              nor the consummation of any other of the transactions herein
              contemplated nor the fulfillment of the terms hereof or of any
              Delayed Delivery Contracts will conflict with, result in a breach
              or violation of, or constitute a default under any law or the
              charter or by-laws of the Company or the terms of any indenture
              or other agreement or instrument known to such counsel and to
              which the Company or any of its subsidiaries is a party or bound
              or any judgment, order or decree known to such counsel to be
              applicable to the Company or any of its subsidiaries of any
              court, regulatory body, administrative agency, governmental body
              or arbitrator having jurisdiction over the Company or any of its
              subsidiaries or any of its or their properties or assets;

                     (x)  to the best of our knowledge, no holders of
              securities of the Company have rights to the registration of such
              securities under the Registration Statement; and

                     (xi)  the statements set forth under the captions [set
              forth appropriate captions relating to tax, regulatory or similar
              legal matters], to the extent they represent statements or
              summaries of legal matters, are true and correct.

       In rendering such opinion, such counsel may rely (A) as to matters
       involving the application of laws of any jurisdiction other than the
       State of Texas or the Federal laws of the United States, to the extent
       they deem proper and specified in such opinion, upon the opinion of
       other counsel of good standing whom they





<PAGE>   19
                                                                              19




       believe to be reliable and who are satisfactory to counsel for the
       Underwriters and (B) as to matters of fact, to the extent they deem
       proper, on certificates of responsible officers of the Company and
       public officials.  References to the Final Prospectus in this paragraph
       (b) include any supplements thereto at the Closing Date.

              (c)  The Representatives shall have received from Cravath, Swaine
       & Moore, counsel for the Underwriters, such opinion or opinions, dated
       the Closing Date, with respect to the issuance and sale of the
       Securities, the Indenture, any Delayed Delivery Contracts, the
       Registration Statement, the Final Prospectus (together with any
       supplement thereto) and other related matters as the Representatives may
       reasonably require, and the Company shall have furnished to such counsel
       such documents as they request for the purpose of enabling them to pass
       upon such matters.

              (d)  The Company shall have furnished to the Representatives a
       certificate of the Company, signed by the Chairman of the Board or the
       President and the principal financial or accounting officer of the
       Company, dated the Closing Date, to the effect that the signers of such
       certificate have carefully examined the Registration Statement, the
       Final Prospectus, any supplements to the Final Prospectus and this
       Agreement and that:

                     (i) the representations and warranties of the Company in
              this Agreement are true and correct in all material respects on
              and as of the Closing Date with the same effect as if made on the
              Closing Date and the Company has complied with all the agreements
              and satisfied all the conditions on its part to be performed or
              satisfied at or prior to the Closing Date; as of the Effective
              Date, the Registration Statement and the Prospectus, including
              the documents incorporated therein by reference, did not include
              any untrue statement of a material fact and did not omit to state
              a material fact required to be stated therein or necessary to
              make the statements therein not misleading and since the
              Effective Date, no event has occurred which should have been set
              forth in a

              Prospectus;

                     (ii) no stop order suspending the effectiveness of the
              Registration Statement has been issued and no proceedings for
              that purpose have been instituted or, to the Company's knowledge,
              threatened; and

                     (iii) since the date of the most recent financial
              statements included in the Final Prospectus (exclusive of any
              supplement thereto), there has been no material adverse change in
              the financial position or results of operations of the Company or
              its subsidiaries, or any change, or any development including a
              prospective change, in or affecting the condition (financial or
              other), earnings, business or properties of the Company and its
              subsidiaries, whether or not arising from transactions in the
              ordinary course of business, except as set forth in or
              contemplated in the Final Prospectus (exclusive of any supplement
              thereto).

              (e)  At the Closing Date, Coopers & Lybrand LLP shall have
       furnished to the Representatives a letter or letters (which may refer to
       letters previously delivered to one or more of the Representatives),
       dated as of the Closing Date, in form and substance satisfactory to the
       Representatives, confirming that they are independent accountants within
       the meaning of the Act and the Exchange Act and the respective
       applicable published rules and regulations thereunder and that they have
       performed a review of the unaudited interim financial information of the
       Company for the six-month period ended April 30, 1997, and as at April
       30, 1997, in accordance with Statement of Auditing Standards No. 71 and
       stating in effect that:

                     (i) in their opinion the audited financial statements and
              financial statement schedules [and pro forma financial
              statements] included or incorporated in the Registration
              Statement and the Final Prospectus and reported on by them comply
              in form in all material respects with the applicable accounting
              requirements of the Act and the

              Exchange Act and the related published rules and regulations;

                     (ii) on the basis of a reading of the latest unaudited
              financial statements made available by the Company and its
              subsidiaries; their limited review, in accordance with standards
              established by the American Institute of Certified Public
              Accountants under Statement of Auditing Standards No. 71, of the
              unaudited interim financial information for the  six-month period
              ended April 30, 1997 and as at April 30, 1997; carrying out
              certain specified procedures (but not an examination in
              accordance with generally accepted auditing standards) which
              would not necessarily reveal matters of significance with respect
              to the comments set forth in such letter; a reading of the
              minutes of the meetings of the stockholders, directors and any
              committees of the Company and the Subsidiaries; and inquiries of
              certain officials of the Company and its subsidiaries who have
              responsibility for financial and accounting matters of the
              Company and its subsidiaries as to transactions and events
              subsequent to October 31, 1996, nothing came to their attention
              which caused them to believe that:

                            (1) any unaudited financial statements included or
                     incorporated in the Registration Statement and the Final
                     Prospectus do not comply in form in all material respects
                     with applicable accounting requirements and with the
                     published rules and regulations of the Commission with
                     respect to financial statements included or incorporated
                     in quarterly reports on Form 10-Q under the Exchange Act;
                     and said unaudited financial statements are not in
                     conformity with generally accepted accounting principles
                     applied on a basis substantially consistent with that of
                     the audited financial statements included or incorporated
                     in the Registration Statement and the Final Prospectus;

                            (2) with respect to the period subsequent to April
                     30, 1997 (other than any capsule information), audited or
                     unaudited,

                     in or incorporated in the Registration Statement and the
                     Final Prospectus, there were any changes, at a specified
                     date not more than five business days prior to the date of
                     the letter, in the long-term debt of the Company and its
                     subsidiaries or capital stock of the Company or decreases
                     in the shareholders' equity of the Company or decreases in
                     working capital of the Company and its subsidiaries as
                     compared with the amounts shown on the most recent
                     consolidated balance sheet included or incorporated in the
                     Registration Statement and the Final Prospectus, or for
                     the period from the date of the most recent financial
                     statements included or incorporated in the Registration
                     Statement and the Final Prospectus to such specified date
                     there were any decreases, as compared with the
                     corresponding period in the preceding year or quarter, in
                     net income or income before income taxes, operating
                     income, or in total or per share amounts of net income of
                     the Company and its subsidiaries, except in all instances
                     for changes or decreases set forth in such letter, in
                     which case the letter shall be accompanied by an
                     explanation by the Company as to the significance thereof
                     unless said explanation is not deemed necessary by the
                     Representatives;

                            (3) the information included in the Registration
                     Statement and Prospectus in response to Regulation S-K,
                     Item 301 (Selected Financial Data), Item 302
                     (Supplementary Financial Information), Item 402 (Executive
                     Compensation) and Item 503(d) (Ratio of Earnings to Fixed
                     Charges) is not in conformity with the applicable
                     disclosure requirements of Regulation S-K; or

                            (4)  the amounts included in any unaudited
                     "capsule" information included or incorporated in the
                     Registration Statement and the Final Prospectus do not
                     agree with the amounts set forth in the unaudited
                     financial statements for the same periods or

                                                                              23




                     were not determined on a basis substantially consistent
                     with that of the corresponding amounts in the audited
                     financial statements included or incorporated in the
                     Registration Statement and the Final Prospectus; and

                     (iii) they have performed certain other specified
              procedures as a result of which they determined that certain
              information of an accounting, financial or statistical nature
              (which is limited to accounting, financial or statistical
              information derived from the general accounting records of the
              Company and its subsidiaries) set forth in the Registration
              Statement and the Final Prospectus and in Exhibit 12 to the
              Registration Statement, including , the information included or
              incorporated in Items [1, 2, 6, 7 and 11] of the Company's Annual
              Report on Form 10-K, incorporated in the Registration Statement
              and the Prospectus, [and] [the information included in the
              "Management's Discussion and Analysis of Financial Condition and
              Results of Operations" included or incorporated in the Company's
              Quarterly Reports on Form 10-Q, incorporated in the Registration
              Statement and the Final Prospectus agrees with the accounting
              records of the Company and its subsidiaries, excluding any
              questions of legal interpretation; and

                     (iv)  if unaudited pro forma financial statements are
              included or incorporated in the Registration Statement and the
              Final Prospectus, on the basis of a reading of the unaudited pro
              forma financial statements, carrying out certain specified
              procedures, inquiries of certain officials of the Company and the
              acquired company who have responsibility for financial and
              accounting  matters, and proving the arithmetic  accuracy of the
              application of the pro forma adjustments to the historical
              amounts in the pro forma financial statements, nothing came to
              their attention which caused them to believe that the pro forma
              financial statements do not comply in form in all material
              respects with the applicable accounting requirements of Rule 11-
              02 of Regulation S-X or that the pro forma adjustments have





<PAGE>   24
                                                                              24




              not been properly applied to the historical amounts in the
              compilation of such statements.

              References to the Final Prospectus in this paragraph (e) include
any supplement thereto at the date of the letter.

              In addition, except as provided in Schedule I hereto, at the
Execution Time, Coopers & Lybrand LLP shall have furnished to the
Representatives a letter or letters, dated as of the Execution Time, in form
and substance satisfactory to the Representatives, to the effect set forth
above.

              (f)  Subsequent to the Execution Time or, if earlier, the dates
       as of which information is given in the Registration Statement
       (exclusive of any amendment thereof) and the Final Prospectus (exclusive
       of any supplement thereto), there shall not have been (i) any change or
       decrease specified in the letter or letters referred to in paragraph (e)
       of this Section 5 or (ii) any change, or any development involving a
       prospective change, in or affecting the condition (financial or
       otherwise), results of operations, business or properties of the Company
       and its subsidiaries the effect of which, in any case referred to in
       clause (i) or (ii) above, is, in the judgment of the Representatives, so
       material and adverse as to make it impractical or inadvisable to proceed
       with the offering or delivery of the Securities as contemplated by the
       Registration Statement (exclusive of any amendment thereof) and the
       Final Prospectus (exclusive of any supplement thereto).

               (g)  Subsequent to the Execution Time, there shall not have been
       any decrease in the rating of any of the Company's debt securities by
       any "nationally recognized statistical rating organization" (as defined
       for purposes of Rule 436(g) under the Act) or any notice given of any
       intended or potential decrease in any such rating or of a possible
       change in any such rating that does not indicate the direction of the
       possible change.

              (h)  Prior to the Closing Date, the Company shall have furnished
       to the Representatives such further





<PAGE>   25
                                                                              25




       information, certificates and documents as the Representatives may
       reasonably request.

              (i)  The Company shall have accepted Delayed Delivery Contracts
       in any case where sales of Contract Securities arranged by the
       Underwriters have been approved by the Company.

              If any of the conditions specified in this Section 5 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives.  Notice of such cancelation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

              The documents required to be delivered by this Section 5 shall be
delivered at the office of Cravath, Swaine & Moore, counsel for the
Underwriters, at Worldwide Plaza, 825 Eighth Avenue, New York, New York, on the
Closing Date.

              6.  Reimbursement of Underwriters' Expenses.  If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 5 hereof is not satisfied,
because of any termination pursuant to Section 9 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally upon demand for all out-of-pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been incurred by them in
connection with the proposed purchase and sale of the Securities.    The
Company agrees with the Underwriters to pay (a) the costs incident to the
authorization, issuance, sale, preparation and delivery of the Securities and
any taxes payable in that connection; (b) the costs incident to the
preparation, printing and filing under the Act of the Registration Statement
and any amendments and exhibits thereto; (c) the costs of distributing the
Registration





<PAGE>   26
                                                                              26




Statement as originally filed and each amendment thereto and any post-effective
amendments thereof (including, in each case, exhibits), any Preliminary
Prospectus, the Prospectus and any amendment or supplement to the Prospectus,
all as provided in this Agreement; (d) the costs of printing, reproducing and
distributing this Agreement and any other underwriting and selling group
documents by mail, telex or other means of communications; (e) the filing fees
incident to securing any required review by the National Association of
Securities Dealers, Inc. of the terms of sale of the Securities; (f) any
applicable listing or other fees; (g) the fees and expenses of qualifying the
Securities under the securities laws of the several jurisdictions and of
preparing, printing and distributing Blue Sky Memoranda and Legal Investment
Surveys (including related reasonable fees and expenses of counsel to the
Underwriters); (h) any fees charged by securities rating services for rating
the Securities; (i) all fees and expenses of the Trustee; and (j) all other
costs and expenses incident to the performance of the obligations of the
Company under this Agreement; provided that, except as otherwise provided in
this Section 6, the Underwriters shall pay their own costs and expenses,
including the costs and expenses of their counsel, any transfer taxes on the
Securities which they may sell and the expenses of advertising any offering of
the Securities made by the Underwriters.

              7.  Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers,
employees and agents of each Underwriter and each person who controls any
Underwriter within the meaning of either the Act or the Exchange Act against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in the Basic Prospectus, any Preliminary Final Prospectus or the Final
Prospectus, or in any amendment thereof or supplement thereto, or arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements





<PAGE>   27
                                                                              27




therein not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made therein in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
any Underwriter through the Representatives specifically for inclusion therein.
This indemnity agreement will be in addition to any liability which the Company
may otherwise have.

              (b)  Each Underwriter severally agrees to indemnify and hold
harmless the Company, each of its directors, each of its officers who signs the
Registration Statement, and each person who controls the Company within the
meaning of either the Act or the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Underwriter, but only with
reference to written information relating to such Underwriter furnished to the
Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have.  The Company acknowledges that the
statements set forth in the last paragraph of the cover page, in the sentences
related to concessions, allowances and stabilization under the heading
"Underwriting" and, if Schedule I hereto provides for sales of Securities
pursuant to delayed delivery arrangements, in the last sentence under the
heading "Delayed Delivery Arrangements" in any Preliminary Final Prospectus or
the Final Prospectus constitute the only information furnished in writing by or
on behalf of the several Underwriters for inclusion in the documents referred
to in the foregoing indemnity, and you, as the Representatives, confirm that
such statements are correct.

              (c)  Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 7, notify the indemnifying party in writing of the
commencement thereof; but the failure so to





<PAGE>   28
                                                                              28




notify the indemnifying party (i) will not relieve it from liability under
paragraph (a) or (b) above unless and to the extent it did not otherwise learn
of such action and such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or (b)
above.  The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent
the indemnified party in any action for which indemnification is sought (in
which case the indemnifying party shall not thereafter be responsible for the
fees and expenses of any separate counsel retained by the indemnified party or
parties except as set forth below); provided, however, that such counsel shall
be satisfactory to the indemnified party.  Notwithstanding the indemnifying
party's election to appoint counsel to represent the indemnified party in an
action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable
fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the indemnifying party to represent the indemnified party would
present such counsel with a conflict of interest, (ii) the actual or potential
defendants in, or targets of, any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have
reasonably concluded that there may be legal defenses available to it and/or
other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not
have employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action or (iv) the indemnifying party shall authorize the indemnified
party to employ separate counsel at the expense of the indemnifying party.

              (d)  In the event that the indemnity provided in paragraph (a) or
(b) of this Section 7 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters agree to
contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Underwriters may be subject in such proportion as is





<PAGE>   29
                                                                              29




appropriate to reflect the relative benefits received by the Company and by the
Underwriters from the offering of the Securities; provided, however, that in no
case shall any Underwriter (except as may be provided in any agreement among
underwriters relating to the offering of the Securities) be responsible for any
amount in excess of the underwriting discount or commission applicable to the
Securities purchased by such Underwriter hereunder.  If the allocation provided
by the immediately preceding sentence is unavailable for any reason, the
Company and the Underwriters shall contribute in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and of the Underwriters in connection with the statements
or omissions which resulted in such Losses as well as any other relevant
equitable considerations.  Benefits received by the Company shall be deemed to
be equal to the total net proceeds from the offering (before deducting
expenses) received by it, and benefits received by the Underwriters shall be
deemed to be equal to the total underwriting discounts and commissions, in each
case as set forth on the cover page of the Final Prospectus.  Relative fault
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information provided by the Company or the
Underwriters, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contribution were determined by pro rata allocation or any other method of
allocation which does not take account of the equitable considerations referred
to above.  Notwithstanding the provisions of this paragraph (d), no person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty
of such fraudulent misrepresentation.  For purposes of this Section 7, each
person who controls an Underwriter within the meaning of either the Act or the
Exchange Act and each director, officer, employee and agent of an Underwriter
shall have the same rights to contribution as such Underwriter, and each person
who controls the Company within the meaning of either the Act or the Exchange
Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to the applicable terms and
conditions of this paragraph (d).  The

Underwriters' obligations to contribute as provided in this paragraph (d) are
several in proportion to their respective underwriting obligations and not
joint.

              8.  Default by an Underwriter.  If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase
shall constitute a default in the performance of its or their obligations under
this Agreement, the remaining Underwriters shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule II hereto bears to the
aggregate principal amount of Securities set forth opposite the names of all
the remaining Underwriters) the Securities which the defaulting Underwriter or
Underwriters agreed but failed to purchase; provided, however, that in the
event that the aggregate principal amount of Securities which the defaulting
Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of
the aggregate principal amount of Securities set forth in Schedule II hereto,
the remaining Underwriters shall have the right to purchase all, but shall not
be under any obligation to purchase any, of the Securities, and if such
nondefaulting Underwriters do not purchase all the Securities, this Agreement
will terminate without liability to any nondefaulting Underwriter or the
Company.  In the event of a default by any Underwriter as set forth in this
Section 8, the Closing Date shall be postponed for such period, not exceeding
seven days, as the Representatives shall determine in order that the required
changes in the Registration Statement and the Final Prospectus or in any other
documents or arrangements may be effected.  Nothing contained in this Agreement
shall relieve any defaulting Underwriter of its liability, if any, to the
Company and any nondefaulting Underwriter for damages occasioned by its default
hereunder.

              9.  Termination.  This Agreement shall be subject to termination
in the absolute discretion of the Representatives, by notice given to the
Company prior to delivery of and payment for the Securities, if prior to such
time (i) trading in the Company's Common Stock shall have been suspended or in
securities generally on the New York Stock Exchange or the NASDAQ National
Market or limited or minimum prices shall have been established on either of
such Exchange or National Market, (ii) a banking moratorium shall have been
declared either by Federal, New York or Texas

State authorities or (iii) there shall have occurred any outbreak or escalation
of hostilities, declaration by the United States of a national emergency or war
or other calamity or crisis or change in general economic, political or
financial conditions the effect of which on financial markets is such as to
make it, in the judgment of the Representatives, impracticable or inadvisable
to proceed with the offering or delivery of the Securities as contemplated by
the Final Prospectus (exclusive of any supplement thereto).

              10.  Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
the Company or its officers and of the Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of any Underwriter or the Company or any
of the officers, directors or controlling persons referred to in Section 7
hereof, and will survive delivery of and payment for the Securities.  The
provisions of Sections 6 and 7 hereof shall survive the termination or
cancelation of this Agreement.

              11.  Notices.  All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telefaxed to  _________________ and confirmed to them, at
the address specified in Schedule I hereto; or, if sent to the Company, will be
mailed, delivered or telefaxed to _________________ and confirmed to it at 3015
SSE Loop 323, Tyler, TX 75713-0489, attention of the legal department.

              12.  Successors.  This Agreement shall inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers and directors and controlling persons referred to in Section 7 hereof,
and no other person will have any right or obligation hereunder.

              13.  Applicable Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

              14.  Counterparts.  This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

Dear Sirs:

              The undersigned hereby agrees to purchase from TCA Cable TV, Inc.
(the "Company"), and the Company agrees to sell to the undersigned, on , 19  ,
(the "Delivery Date"), $       principal amount of the Company's

and related Prospectus Supplement dated           , 19  , receipt of a copy of
which is hereby acknowledged, at a purchase price of    % of the principal
amount thereof, plus [accrued interest] [amortization of original issue
discount], if any, thereon from           , 19  , to the date of payment and
delivery, and on the further terms and conditions set forth in this contract.

              Payment for the Securities to be purchased by the undersigned
shall be made on or before 11:00 AM, New York City time, on the Delivery Date
to or upon the order of the Company in New York Clearing House (next day)
funds, at your office or at such other place as shall be agreed between the
Company and the undersigned, upon delivery to the undersigned of the Securities
in definitive fully registered form and in such authorized denominations and
registered in such names as the undersigned may request by written or
telegraphic communication addressed to the Company not less than five full
business days prior to the Delivery Date.  If no request is received, the
Securities will be registered in the name of the undersigned and issued in a
denomination equal to the aggregate principal amount of Securities to be
purchased by the undersigned on the Delivery Date.

              The obligation of the undersigned to take delivery of and make
payment for Securities on the Delivery Date, and the obligation of the Company
to sell and deliver Securities on the Delivery Date, shall be subject to the

the failure thereof) that (1) the purchase of Securities to be made by the
undersigned, which purchase the undersigned represents is not prohibited on the
date hereof, shall not on the Delivery Date be prohibited under the laws of the
jurisdiction to which the undersigned is subject, and (2) the Company, on or
before the Delivery Date, shall have sold to certain underwriters (the
"Underwriters") such principal amount of the Securities as is to be sold to
them pursuant to the Underwriting Agreement referred to in the Prospectus and
Prospectus Supplement mentioned above.  Promptly after completion of such sale
to the Underwriters, the Company will mail or deliver to the undersigned at its
address set forth below notice to such effect, accompanied by a copy of the
opinion of counsel for the Company delivered to the Underwriters in connection
therewith.  The obligation of the undersigned to take delivery of and make
payment for the Securities, and the obligation of the Company to cause the
Securities to be sold and delivered, shall not be affected by the failure of

to other contracts similar to this contract.

the parties hereto and their respective successors, but will not be assignable

              (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness to such
execution or by the certificate of any notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument or writing acknowledged to him the execution
thereof.  Where such execution is by an officer of a corporation or a member of
a partnership, on behalf of such corporation or partnership, such certificate
or affidavit shall also constitute sufficient proof of his authority.  The fact
and date of the execution of any such instrument or writing, or the authority
of the person executing the same, may also be proved in any other manner which
the Trustee deems sufficient.

              (c)  The ownership of Securities shall be proved by the Security

for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other action, but the
Company shall have no obligation to do so.  Such record date shall be the later
of 10 days prior to the first solicitation of such action or the date of the
most recent list of Holders furnished to the Trustee pursuant to Section 701.
If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other action may be given before or after the record
date, but only the Holders of record at the close of business on the record
date shall be deemed to be Holders for the purposes of determining whether
Holders of the requisite proportion of Securities outstanding have authorized
or agreed or consented to such request, demand,





<PAGE>   31
                                                                              22

authorization, direction, notice, consent, waiver or other action, and for that
purpose the Securities Outstanding shall be computed as of the record date;
provided that no such authorization, agreement or consent by the Holders on the
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than six months after the record
date, and that no such authorization, agreement or consent may be amended,
withdrawn or revoked once given by a Holder, unless the Company shall provide
for such amendment, withdrawal or revocation in conjunction with such
solicitation of authorizations, agreements or consents or unless and to the
extent required by applicable law.

              (e)  Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Security shall bind the
Holder of every Security issued upon the registration of transfer thereof or in
exchange therefor or in lieu thereof, in respect of anything done or suffered
to be done by the Trustee or the Company in reliance thereon whether or not
notation of such action is made upon such Security.

              Section 105.  Notices, etc., to Trustee and Company.  Any
request, demand, authorization, direction, notice, consent, waiver or Act of
Securityholders or other document provided or permitted by this Indenture to be
made upon, given or furnished to, or filed with,

              (1) the Trustee by any Securityholder or by the Company shall be
       sufficient for every purpose hereunder if made, given, furnished or
       filed in writing to or with the Trustee at its Corporate Trust Office,
       Attention:  Corporate Trust Department, or

              (2) the Company by the Trustee or by any Securityholder shall be
       sufficient for every purpose hereunder (except as provided in Section
       501(4) and (5) or, in the case of a request for repayment, as specified
       in the Security carrying the right to repayment) if in writing and
       mailed, first-class postage prepaid, to the Company addressed to it at
       the address of its principal





<PAGE>   32
                                                                              23

       office specified in the first paragraph of this instrument, Attention:
       Treasurer, or at any other address previously furnished in writing to
       the Trustee by the Company.

              Section 106.  Notices to Securityholders; Waiver.  Where this
Indenture or any Security provides for notice to Securityholders of any event,
such notice shall be sufficiently given (unless otherwise herein or in such
Security expressly provided) if in writing and mailed, first-class postage
prepaid, to each Securityholder affected by such event, at his address as it
appears in the Security Register, not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice.  In
any case where notice to Securityholders is given by mail, neither the failure
to mail such notice, nor any defect in any notice so mailed, to any particular
Securityholder shall affect the sufficiency of such notice with respect to
other Securityholders.  Where this Indenture or any Security provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice.  Waivers of notice by
Securityholders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

              In case, by reason of the suspension of regular mail service as a
result of a strike, work stoppage or otherwise, it shall be impractical to mail
notice of any event to any Securityholder when such notice is required to be
given pursuant to any provision of this Indenture, then any method of
notification as shall be satisfactory to the Trustee and the Company shall be
deemed to be a sufficient giving of such notice.

              Section 107.  Conflict with Trust Indenture Act.  If and to the
extent that any provision hereof limits, qualifies or conflicts with the duties
imposed by, or with another provision (an "incorporated provision") included in
this Indenture by operation of, any of Sections 310 to 318,





<PAGE>   33

due in respect of the principal of, or premium or interest, if any, on the
Securities of any series (the "Required Currency") into a currency in which a

              Section 204.  Securities Issuable in the Form of a Global
Security.  (a)  If the Company shall establish pursuant to Sections 202 and 301
that the Securities of a particular series are to be issued in whole or in part
in the form of one or more Global Securities, then the Company shall execute
and the Trustee or its agent shall, in accordance with Section 303 and the
Company Order delivered to the Trustee or its agent thereunder, authenticate
and deliver, such Global Security or Securities, which (i) shall represent, and
shall be denominated in an amount equal to the aggregate principal amount of,
the Outstanding Securities of such series to be represented by such Global
Security or Securities, or such portion thereof as the Company shall specify in
a Company Order, (ii) shall be registered in the name of the Depository for
such Global Security or Securities or its nominee, (iii) shall be delivered by
the Trustee or its agent to the Depository or pursuant to the Depository's
instruction and (iv) shall bear a legend substantially to the following effect:
"Unless this certificate is presented by an authorized representative of the
Depository to Issuer or its agent for registration of transfer, exchange, or
payment, and any certificate issued is registered in the name of the nominee of
the Depository or in such other name as is requested by an authorized
representative of the Depository (and any payment is made to the nominee of the
Depository or to such other entity as is requested by an authorized
representative of the Depository), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch

       as the registered owner hereof, the nominee of the Depository, has an
       interest herein."

              (b)    Notwithstanding any other provision of this Section 204 or
of Section 305, and subject to the provisions of paragraph (c) below, unless
the terms of a Global Security expressly permit such Global Security to be
exchanged in whole or in part for individual Securities, a Global Security may
be transferred, in whole but not in part and in the manner provided in Section
305, only to a nominee of the Depository for such Global Security, or to the
Depository, or a successor Depository for such Global Security selected or
approved by the Company, or to a nominee of such successor Depository.

              (c)  (i)  If at any time the Depository for a Global Security
notifies the Company that it is unwilling or unable to continue as Depository
for such Global Security or if at any time the Depository for the Securities
for such series shall no longer be eligible or in good standing under the
Securities Exchange Act of 1934, as amended, or other applicable statute or
regulation, the Company shall appoint a successor Depository with respect to
such Global Security.  If a successor Depository for such Global Security is
not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such ineligibility, the Company will execute, and
the Trustee or its agent, upon receipt of a Company Request for the
authentication and delivery of individual Securities of such series in exchange
for such Global Security, will authenticate and deliver, individual Securities
of such series of like tenor and terms in an aggregate principal amount equal
to the principal amount of the Global Security in exchange for such Global
Security.

              (ii)  The Company may at any time and in its sole discretion
determine that the Securities of any series (or portion thereof) issued or
issuable in the form of one or more Global Securities shall no longer be
represented by such Global Security or Securities.  In such event the Company
will execute, and the Trustee, upon receipt of a Company Request for the
authentication and delivery of

                                                                              29

individual Securities of such series in exchange (in whole or in part) for such
Global Security, will authenticate and deliver individual Securities of such
series of like tenor and terms in definitive form in an aggregate principal
amount equal to the principal amount of such Global Security or Securities
representing such series (or portion thereof) in exchange for such Global
Security or Securities.

              (iii)  If specified by the Company pursuant to Sections 202 and
301 with respect to Securities issued or issuable in the form of a Global
Security, the Depository for such Global Security may surrender such Global
Security in exchange in whole (or in part) for individual Securities of such
series of like tenor and terms in definitive form on such terms as are
acceptable to the Company and such Depository.  Thereupon the Company shall
execute, and the Trustee or its agent shall authenticate and deliver, without
service charge, (1) to each Person specified by such Depository a new Security
or Securities of the same series of like tenor and terms and of any authorized
denomination as requested by such Person in aggregate principal amount equal to
and in exchange for such Person's beneficial interest as specified by such
Depository in the Global Security; and (2) to such Depository a new Global
Security of like tenor and terms and in an authorized denomination equal to the
difference, if any, between the principal amount of the surrendered Global
Security and the aggregate principal amount of Securities delivered to Holders
thereof.

              (iv)   In any exchange provided for in any of the preceding three
paragraphs, the Company will execute and the Trustee or its agent will
authenticate and deliver individual Securities in definitive registered form in
authorized denominations.  Upon the exchange of the entire principal amount of
a Global Security for individual Securities, such Global Security shall be
canceled by the Trustee or its agent.  Except as provided in the preceding
paragraph, Securities issued in exchange for a Global Security pursuant to this
Section shall be registered in such names and in such authorized denominations
as the Depository for such Global Security, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the

deliver at its Corporate Trust Office such Securities to the Persons in whose
names such Securities are so registered.

Company to the Trustee for authentication; and the Trustee shall, upon Company
Order, authenticate and deliver such Securities as in this Indenture provided

       Company has the corporate power to issue such Securities and such
       Securities have been duly authorized and delivered by the Company and,

       legal, valid and binding obligations of the Company enforceable in
       accordance with their terms (subject, as to enforcement of remedies, to

              (5) such other matters as the Trustee may reasonably request;

and, if the authentication and delivery relates to a new series of Securities
created by an indenture supplemental hereto, also stating that all laws and
requirements with respect to the form and execution by the Company of the
supplemental indenture with respect to that series of Securities have been
complied with, the Company has corporate power to execute and deliver any such
supplemental indenture and has taken all necessary corporate action for those
purposes and any such supplemental indenture has been executed and delivered
and constitutes the legal, valid and binding obligation of the Company
enforceable in accordance with its terms (subject, as to enforcement of
remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or
other laws and legal principles affecting creditors' rights generally from time

immunities under the Securities and this Indenture.

all Securities shall be dated the date of their authentication.

                                                                              37

executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.  Notwithstanding
the foregoing, if any Security shall have been authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancelation as provided in Section
309, for all purposes of this Indenture such Security shall be deemed never to
have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture.

              Section 304.  Temporary Securities.  Pending the preparation of
definitive Securities of any series, the Company may execute, and, upon receipt
of the documents required by Section 303, together with a Company Order, the
Trustee shall authenticate and deliver, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive
Securities in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Securities may determine, as evidenced by their execution of
such Securities.

              If temporary Securities of any series are issued, the Company
will cause definitive Securities of such series to be prepared without
unreasonable delay.  After the preparation of definitive Securities, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment, without
charge to the Holder; and upon surrender for cancelation of any one or more
temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of such series of authorized denominations and of like
tenor and terms.  Until so exchanged the temporary Securities of such series
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

                                                                              38

              Section 305.  Registration, Transfer and Exchange.  The Company
shall keep or cause to be kept a register or registers (herein sometimes
referred to as the "Security Register") in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities, or of Securities of a particular series, and of transfers of
Securities or of Securities of such series.  Any such register shall be in
written form or in any other form capable of being converted into written form
within a reasonable time.  At all reasonable times the information contained in
such register or registers shall be available for inspection by the Trustee at
the office or agency to be maintained by the Company as provided in Section
1002.  There shall be only one Security Register per series of Securities.

              Subject to Section 204, upon surrender for registration of
transfer of any Security of any series at the office or agency of the Company
maintained for such purpose in a Place of Payment, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of such series of any
authorized denominations, of a like aggregate principal amount and Stated
Maturity and of like tenor and terms.

              Subject to Section 204, at the option of the Holder, Securities
of any series may be exchanged for other securities of such series of any
authorized denominations, of a like aggregate principal amount and Stated
Maturity and of like tenor and terms, upon surrender of the Securities to be
exchanged at such office or agency.  Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities which the Securityholder making the exchange is
entitled to receive.

              All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the





<PAGE>   48
                                                                              39

Securities surrendered upon such registration of transfer or exchange.

              Every Security presented or surrendered for registration of
transfer or exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed, by the Holder
thereof or his attorney duly authorized in writing.

              Unless otherwise provided in the Security to be registered for
transfer or exchanged, no service charge shall be made on any Securityholder
for any registration of transfer or exchange of Securities, but the Company may
(unless otherwise provided in such Security) require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer.

              The Company shall not be required (i) to issue, register the
transfer of or exchange any Security of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of such series selected for redemption under Section
1103 and ending at the close of business on the date of such mailing, or (ii)
to register the transfer of or exchange any Security so selected for redemption
in whole or in part.

              None of the Company, the Trustee, any agent of the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

              Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.
If (i) any mutilated Security is surrendered





<PAGE>   49
                                                                              40

to the Trustee, or the Company and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Security, and (ii) there
is delivered to the Company and the Trustee such security or indemnity as may
be required by then to save each of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its written request the
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Security, a new Security of like tenor,
series, Stated Maturity and principal amount, bearing a number not
contemporaneously outstanding.

              In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

              Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

              Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of the same series duly issued hereunder.

              The provisions of this Section are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

              Section 307.  Payment of Interest; Interest Rights Preserved.
Unless otherwise provided with respect to such





<PAGE>   50
                                                                              41

Security pursuant to Section 301, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

              Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of his having
been such Holder; and, except as hereinafter provided, such Defaulted Interest
may be paid by the Company, at its election in each case, as provided in Clause
(l) or Clause (2) below:

              (1)  The Company may elect to make payment of any Defaulted
       Interest to the Persons in whose names any such Securities (or their
       respective Predecessor Securities) are registered at the close of
       business on a Special Record Date for the payment of such Defaulted
       Interest, which shall be fixed in the following manner.  The Company
       shall notify the Trustee in writing of the amount of Defaulted Interest
       proposed to be paid on each such Security and the date of the proposed
       payment, and at the same time the Company shall deposit with the Trustee
       an amount of money equal to the aggregate amount proposed to be paid in
       respect of such Defaulted Interest or shall make arrangements
       satisfactory to the Trustee for such deposit prior to the date of the
       proposed payment, such money when deposited to be held in trust for the
       benefit of the Persons entitled to such Defaulted Interest as in this
       Clause provided.  Thereupon the Trustee shall fix a Special Record Date
       for the payment of such Defaulted Interest which shall be not more than
       15 nor less than 10 days prior to the date of the proposed payment and
       not less than 10 days after the receipt by the Trustee of the notice of
       the proposed payment.  The Trustee shall promptly notify the Company of
       such Special Record Date and, in the name and at the expense of the
       Company,





<PAGE>   51
                                                                              42

       shall cause notice of the proposed payment of such Defaulted Interest
       and the Special Record Date therefor to be mailed, first-class postage
       prepaid, to the Holder of each such Security at his address as it
       appears in the Security Register, not less than 10 days prior to such
       Special Record Date.  Notice of the proposed payment of such Defaulted
       Interest and the Special Record Date therefor having been mailed as
       aforesaid, such Defaulted Interest shall be paid to the Persons in whose
       names such Securities (or their respective Predecessor Securities) are
       registered on such Special Record Date and shall no longer be payable
       pursuant to the following Clause (2).

              (2)  The Company may make payment of any Defaulted Interest in
       any other lawful manner not inconsistent with the requirements of any
       securities exchange on which such Securities may be listed, and upon
       such notice as may be required by such exchange, if, after notice given
       by the Company to the Trustee of the proposed payment pursuant to this
       Clause, such manner of payment shall be deemed practicable by the
       Trustee.

              If any installment of interest the Stated Maturity of which is on
or prior to the Redemption Date for any Security called for redemption pursuant
to Article Eleven is not paid or duly provided for on or prior to the
Redemption Date in accordance with the foregoing provisions of this Section,
such interest shall be payable as part of the Redemption Price of such
Securities.

              Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

              Section 308.  Persons Deemed Owners.  The Company, the Trustee
and any agent of the Company or the Trustee may treat the Person in whose name
any Security is registered as the owner of such Security for the purpose of
receiving

                                                                              43

payment of principal of (and premium, if any), and (subject to Section 307)
interest on, such Security and for all other purposes whatsoever, whether or
not such Security be overdue, and neither the Company, the Trustee nor any
agent of the Company or the Trustee shall be affected by notice to the
contrary.

              None of the Company, the Trustee, any Paying Agent or the
Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests in a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

              Section 309.  Cancelation.  All Securities surrendered for
payment, conversion, redemption, registration of transfer, exchange or credit
against a sinking fund shall, if surrendered to any Person other than the
Trustee, be delivered to the Trustee and, if not already canceled, shall be
promptly canceled by it.  The Company may at any time deliver to the Trustee
for cancelation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and all
Securities so delivered shall be promptly canceled by the Trustee.  No Security
shall be authenticated in lieu of or in exchange for any Securities canceled as
provided in this Section, except as expressly permitted by this Indenture.  The
Trustee shall dispose of all canceled Securities in accordance with its
standard procedures and deliver a certificate of such disposition to the
Company.

              Section 310.  Computation of Interest.  Unless otherwise provided
as contemplated in Section 301, interest on the Securities shall be calculated
on the basis of a 360-day year of twelve 30-day months.

              Section 311.  Delayed Issuance of Securities.  Notwithstanding
any contrary provision herein, if all Securities of a series are not to be
originally issued at one time, it shall not be necessary for the Company to





<PAGE>   53
                                                                              44

deliver to the Trustee an Officers' Certificate, Board Resolution, supplemental
indenture, Opinion of Counsel or Company Order otherwise required pursuant to
Sections 102, 202, 301 and 303 at or prior to the time of authentication of
each Security of such series if such documents are delivered to the Trustee or
its agent at or prior to the authentication upon original issuance of the first
Security of such series to be issued; provided that any subsequent request by
the Company to the Trustee to authenticate Securities of such series upon
original issuance shall constitute a representation and warranty by the Company
that as of the date of such request, the statements made in the Officers'
Certificate or other certificates delivered pursuant to Sections 102 and 202
shall be true and correct as if made on such date.

              A Company Order, Officers' Certificate or Board Resolution or
supplemental indenture delivered by the Company to the Trustee in the
circumstances set forth in the preceding paragraph may provide that Securities
which are the subject thereof will be authenticated and delivered by the
Trustee or its agent on original issue from time to time in the aggregate
principal amount, if any, established for such series pursuant to such
procedures acceptable to the Trustee as may be specified from time to time by
Company Order upon the telephonic, electronic or written order of Persons
designated in such Company Order, Officers' Certificate, supplemental indenture
or Board Resolution (any such telephonic or electronic instructions to be
promptly confirmed in writing by such Persons) and that such Persons are
authorized to determine, consistent with such Company Order, Officers'
Certificate, supplemental indenture or Board Resolution, such terms and
conditions of said Securities as are specified in such Company order, Officers'
Certificate, supplemental indenture or Board Resolution.

              Section 401.  Satisfaction and Discharge of Indenture.  This
Indenture shall cease to be of further effect with respect to any series of
Securities (except as to any surviving rights of conversion or transfer or
exchange of Securities of such series expressly provided for herein or in the
form of Security for such series), and the Trustee, on receipt of a Company
Request and at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of this Indenture as to such series,
when

              (1) either

                     (A) all Securities of that series theretofore
       authenticated and delivered (other than (i) Securities of such series
       which have been destroyed, lost or stolen and which have been replaced
       or paid as provided in Section 306, and (ii) Securities of such series
       for whose payment money in the Required Currency has theretofore been
       deposited in trust or segregated and held in trust by the Company and

       delivered to the Trustee canceled or for cancelation

                            (i) have become due and payable, or

                            (ii) will become due and payable at their Stated
              Maturity within one year, or

                            (iii) are to be called for redemption within one
              year under arrangements satisfactory to the Trustee for the

              by the Trustee in the name, and at the expense, of the Company,

       and the Company, in the case of (i), (ii) or (iii) above, has
       irrevocably deposited or caused to be deposited with the Trustee as
       trust funds in trust for the purpose an amount in the Required Currency
       sufficient to pay and discharge the entire indebtedness on such
       Securities not theretofore delivered to the Trustee canceled or for
       cancelation, for principal (and premium, if any) and interest to the
       date of such deposit (in the case of Securities which have become due
       and payable), or to the Stated Maturity or Redemption Date, as the case
       may be;

              (2) the Company has paid or caused to be paid all other sums
       payable hereunder by the Company with respect to the Securities of such
       series; and

              (3) the Company has delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel each stating that all conditions
       precedent herein provided for relating to the satisfaction and discharge
       of this Indenture with respect to the Securities of such series have
       been complied with.

Notwithstanding the satisfaction and discharge of this Indenture with respect
to any series of Securities, the obligations of the Company to the Trustee with
respect to that series under Section 607 shall survive and the obligations of
the Company and the Trustee under Sections 305, 306, 402, 1002 and 1003 shall
survive.

              Section 402.  Application of Trust Money.  Subject to the
provisions of the last paragraph of Section 1003, all money deposited with the
Trustee pursuant to Section 401 or Section 403 shall be held in trust and
applied by it, in accordance with the provisions of the series of Securities in
respect of which it was deposited and this Indenture, to the payment, either
directly or through any Paying Agent (including the Company acting as its own
Paying Agent) as the Trustee may determine, to the Persons entitled thereto,

of the principal (and premium, if any) and interest for whose payment such
money has been deposited with the Trustee; but such money need not be
segregated from other funds except to the extent required by law.

              Anything herein to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or securities deposited with and held by it as provided in Section 403
and this Section 402 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent satisfaction and discharge,
Discharge or covenant defeasance, provided that the Trustee shall not be
required to liquidate any securities in order to comply with the provisions of
this paragraph.

              Section 403.  Defeasance Upon Deposit of Funds or Governmental
Obligations.  Unless pursuant to Section 301 provision is made that this
Section shall not be applicable to the Securities of any series, at the
Company's option, either (a) the Company shall be deemed to have been
Discharged (as defined below) from its obligations with respect to any series
of Securities after the applicable conditions set forth below have been
satisfied or (b) the Company shall cease to be under any obligation to comply
with any term, provision or condition set forth in Sections 1005, 1006, 1007
and 1008 and Article Eight (and any other Sections or covenants applicable to
such Securities that are determined pursuant to Section 301 to be subject to
this provision), and clause (5) of Section 501 of this Indenture (and any other
Events of Default applicable to such Securities that are determined pursuant to
Section 301 to be subject to this provision) shall be deemed not to be an Event
of Default, with respect to any series of Securities at any time after the
applicable conditions set forth below have been satisfied:

              (1) the Company shall have deposited or caused to be deposited
       irrevocably with the Trustee as trust





<PAGE>   57
                                                                              48

       funds in trust, specifically pledged as security for, and dedicated
       solely to, the benefit of the Holders of the Securities of such series
       (i) money in an amount, or (ii) the equivalent in securities of the
       government which issued the currency in which the Securities are
       denominated or government agencies backed by the full faith and credit
       of such government which through the payment of interest and principal
       in respect thereof in accordance with their terms will provide, not
       later than one day before the due date of any payment, money in an
       amount, or (iii) a combination of (i) and (ii), sufficient, in the
       opinion (with respect to (ii) and (iii)) of a nationally recognized firm
       of independent public accountants expressed in a written certification
       thereof delivered to the Trustee, to pay and discharge each installment
       of principal (including mandatory sinking fund payments) and any premium
       of, interest on and any repurchase or redemption obligations with
       respect to the outstanding Securities of such series on the dates such
       installments of interest or principal or repurchase or redemption
       obligations are due (before such a deposit, if the Securities of such
       series are then redeemable or may be redeemed in the future pursuant to
       the terms thereof, in either case at the option of the Company, the
       Company may give to the Trustee, in accordance with Section 1102, a
       notice of its election to redeem all of the Securities of such series at
       a future date in accordance with Article Eleven);

              (2) no Event of Default or event (including such deposit) which
       with notice or lapse of time would become an Event of Default with
       respect to the Securities of such series shall have occurred and be
       continuing on the date of such deposit;

              (3) the Company shall have delivered to the Trustee (A) an
       Opinion of Counsel to the effect that Holders of the Securities of such
       series will not recognize income, gain or loss for Federal income tax
       purposes as a result of the Company's exercise of its option under this
       Section 403 and will be subject to





<PAGE>   58
                                                                              49

       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 option had not been
       exercised, and, in the case of Securities being Discharged, accompanied
       by a ruling to that effect from the Internal Revenue Service, unless, as
       set forth in such opinion of Counsel, there has been a change in the
       applicable federal income tax law since the date of this Indenture such
       that a ruling from the Internal Revenue Service is no longer required
       and (B) an opinion of Counsel, subject to such qualifications,
       exceptions, assumptions and limitations as are reasonably deemed
       necessary by such counsel and are reasonably satisfactory to counsel for
       the Trustee, to the effect that the trust resulting from the deposit
       referred to in paragraph (1) above does not violate the Investment
       Company Act of 1940;

              (4) the Company shall have delivered to the Trustee an Officers'
       Certificate stating that the deposit referred to in paragraph (1) above
       was not made by the Company with the intent of preferring the Holders
       over other creditors of the Company or with the intent of defeating,
       hindering, delaying or defrauding creditors of the Company or others;
       and

              (5) the Company shall have delivered to the Trustee an Officers'
       Certificate and an Opinion of Counsel each stating that all conditions
       precedent herein provided for relating to the satisfaction and discharge
       of this Indenture with respect to the Securities of such series have
       been complied with.

              "Discharged" means that the Company shall be deemed to have paid
and discharged the entire indebtedness represented by, and obligations under,
the Securities of such series and to have satisfied all the obligations under
this Indenture relating to the Securities of such series (and the Trustee, on
receipt of a Company Request and at the expense of the Company, shall execute
proper instruments acknowledging the same), except (A) the rights of Holders of
securities to receive, from the trust fund described in clause (1) above,
payment of the principal and any premium

of and any interest on such Securities when such payments are due; (B) the
Company's obligations with respect to such Securities under Sections 305, 306,
402, 607, 1002 and 1003; (C) the Company's right of redemption, if any, with
respect to any Securities of such series pursuant to Article Eleven, in which
case the Company may redeem the Securities of such series in accordance with
Article Eleven by complying with such Article and depositing with the Trustee,
in accordance with Section 1105, an amount of money sufficient, together with
all amounts held in trust pursuant to Section 402 with respect to Securities of
such series, to pay the Redemption Price of all the Securities of such series
to be redeemed; and (D) the rights, powers, trusts, duties and immunities of
the Trustee hereunder.

              Section 404.  Reinstatement.  If the Trustee or Paying Agent is
unable to apply any money or securities in accordance with Section 402 of this
Indenture, by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to Section 401 or 403 of this Indenture, as the
case may be, until such time as the Trustee or Paying Agent is permitted to
apply all such money or securities in accordance with Section 402 of this
Indenture; provided that, if the Company has made any payment of principal of
or interest on any Securities because of the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
to receive such payment from the money or securities held by the Trustee or
Paying Agent.

the reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body), unless such event is either inapplicable
to a particular series or it is specifically deleted or modified in or pursuant
to the supplemental indenture or Board Resolution creating such series of
Securities or in the form of Security for such series:

              (1) default in the payment of any interest upon any Security of
       that series when it becomes due and payable, and continuance of such
       default for a period of 30 consecutive days; or

              (2) default in the payment of the principal of (or premium, if
       any, on) any Security of that series at its Maturity; or

              (3) default in the payment of any sinking or purchase fund or

       or under any mortgage, indenture or instrument under which there may be
       issued or by which there may be secured or evidenced any indebtedness
       for money borrowed by the Company (including this Indenture), whether
       such indebtedness now exists or shall hereafter be created, which
       default (i) shall constitute a failure to pay the principal of such
       indebtedness having an outstanding principal amount in excess of $5
       million in the aggregate when due and payable at the final (but not any
       interim) maturity thereof after the expiration of any applicable grace
       period with respect thereto and the holders of such indebtedness shall
       not have waived such default or (ii) shall have resulted in such
       indebtedness having an outstanding principal

       declared due and payable prior to the date on which it would otherwise
       have become due and payable, in either case without such indebtedness
       having been discharged, or such acceleration having been rescinded or
       annulled, within a period of 30 consecutive days after there shall have
       been given, by registered or certified mail, to the Company by the
       Trustee or to the Company and the Trustee by the Holders of at least 25%
       in principal amount of the Outstanding Securities of such series, a
       written notice specifying such default and requiring the Company to

       be rescinded or annulled and stating that such notice is a "Notice of
       Default" hereunder; or

              (5) default in the performance, or breach, of any covenant or
       warranty of the Company in this Indenture in respect of the Securities
       of such series (other than a covenant or warranty in respect of the
       Securities of such series a default in the performance of which or the
       breach of which is elsewhere in this Section specifically dealt with),
       all of such covenants and warranties in the Indenture which are not
       expressly stated to be for the benefit of a particular series of
       Securities being deemed in respect of the Securities of all series for
       this purpose, and continuance of such default or breach for a period of
       30 consecutive days after there has been given, by registered or
       certified mail, to the Company by the Trustee or to the Company and the
       Trustee by the Holders of at least 25% in principal amount of the
       Outstanding Securities of such series, a written notice specifying such

       Significant Subsidiary a bankrupt or

       liquidation of its affairs, and the continuance of any such decree or
       order unstayed and in effect for a period of 30 consecutive days; or

              (7) the consent by the Company or any Significant Subsidiary to
       the institution of bankruptcy or insolvency proceedings against it, or
       the filing by it of a petition or answer or consent seeking

       creditors, or the admission by it in writing of its inability to pay its
       debts generally as they become due, or the taking of corporate action by
       the Company or any Significant Subsidiary in furtherance of any such
       action; or

              (8) any other Event of Default provided in the supplemental
       indenture or Board Resolution under which such series of Securities is
       issued or in the form of Security for such series.

              Section 502.  Acceleration of Maturity; Rescission and Annulment.
If an Event of Default described in paragraph (1), (2), (3), (4), (5) or (8)
(if the Event of Default under paragraph (5) or (8) is with respect to less
than all series of Securities then Outstanding) of Section 501 occurs and is
continuing with respect to any series,





<PAGE>   63
                                                                              54

       then and in each and every such case, unless the principal of all the
       Securities of such series shall have already become due and payable,
       either the Trustee or the Holders of not less than 25% in aggregate
       principal amount of the Securities of such series then Outstanding
       hereunder (each such series acting as a separate class), by notice in
       writing to the Company (and to the Trustee if given by Holders), may
       declare the principal amount (or, if the Securities of such series are
       Original Issue Discount Securities, such portion of the principal amount
       as may be specified in the terms of that series) of all the Securities
       of such series and all accrued interest thereon to be due and payable
       immediately, and upon any such declaration the same shall become and
       shall be immediately due and payable, anything in this Indenture or in
       the Securities of such series contained to the contrary notwithstanding.
       If an Event of Default described in paragraph (5) or (8) (if the Event
       of Default under paragraph (5) or (8) is with respect to all series of
       Securities then Outstanding), of Section 501 occurs and is continuing,
       then and in each and every such case, unless the principal of all the
       Securities shall have already become due and payable, either the Trustee
       or the Holders of not less than 25% in aggregate principal amount of all
       the Securities then Outstanding hereunder (treated as one class), by
       notice in writing to the Company (and to the Trustee if given by
       Holders), may declare the principal amount (or, if any Securities are
       Original Issue Discount Securities, such portion of the principal amount
       as may be specified in the terms thereof) of all the Securities then
       Outstanding and all accrued interest thereon to be due and payable
       immediately, and upon any such declaration the same shall become and
       shall be immediately due and payable, anything in this Indenture or in
       the Securities contained to the contrary notwithstanding.  If an Event
       of Default of the type set forth in subparagraph 6 or subparagraph 7 of
       Section 501 occurs and is continuing, the principal of and any interest
       on the Securities then Outstanding shall become immediately due and
       payable.

              At any time after such a declaration of acceleration has been
made with respect to the Securities of any or all series, as the case may be,
and before a judgment or

                                                                              55

decree for payment of the money due has been obtained by the Trustee as
hereinafter in this Article provided, the Holders of a majority in principal
amount of the Outstanding Securities of such series, by written notice to the
Company and the Trustee, may rescind and annul such declaration and its
consequences if

              (1) the Company has paid or deposited with the Trustee a sum
       sufficient to pay

                            (A) all overdue installments of interest on the
              Securities of such series,

                            (B) the principal of (and premium, if any, on) any
              Securities of such series which have become due otherwise than by
              such declaration of acceleration, and interest thereon at the
              rate or rates prescribed therefor by the terms of the Securities
              of such series, to the extent that payment of such interest is
              lawful,

                            (C) interest upon overdue installments of interest
              at the rate or rates prescribed therefor by the terms of the
              Securities of such series to the extent that payment of such
              interest is lawful, and

                            (D) all sums paid or advanced by the Trustee
              hereunder and the reasonable compensation, expenses,
              disbursements and advances of the Trustee, its agents and counsel
              and all other amounts due the Trustee under Section 607; and

              (2) all Events of Default with respect to such series of
       Securities, other than the nonpayment of the principal of the Securities
       of such series which have become due solely by such acceleration, have
       been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                                                                              56

              Section 503.  Collection of Indebtedness and Suits for
Enforcement by Trustee.  The Company covenants that if

              (1) default is made in the payment of any installment of interest
       on any Security of any series when such interest becomes due and
       payable, or

              (2) default is made in the payment of the principal of (or
       premium, if any, on) any Security at the Maturity thereof, or

              (3) default is made in the payment of any sinking or purchase
       fund or analogous obligation when the same becomes due by the terms of
       the Securities of any series,

and any such default continues for any period of grace provided with respect to
the Securities of such series, the Company will, upon demand of the Trustee,
pay to it, for the benefit of the Holder of any such Security (or the Holders
of any such series in the case of Clause (3) above), the whole amount then due
and payable on any such Security (or on the Securities of any such series in
the case of Clause (3) above) for principal (and premium, if any) and interest,
with interest, to the extent that payment of such interest shall be legally
enforceable, upon the overdue principal (and premium, if any) and upon overdue
installments of interest, at such rate or rates as may be prescribed therefor
by the terms of any such Security (or of Securities of any such series in the
case of Clause (3) above); and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and all other amounts due the Trustee under
Section 607.

              If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, and may prosecute such proceeding to judgment or final





<PAGE>   66
                                                                              57

decree, and may enforce the same against the Company or any other obligor upon
the Securities of such series and collect the money adjudged or decreed to be
payable in the manner provided by law out of the property of the Company or any
other obligor upon such Securities, wherever situated.

              If an Event of Default with respect to any series of Securities
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

              Section 504.  Trustee May File Proofs of Claim.  In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Securities shall then be
due and payable as therein expressed or by declaration or otherwise and
irrespective of whether the Trustee shall have made any demand on the Company
for the payment of overdue principal or interest) shall be entitled and
empowered, by intervention in such proceedings or otherwise,

              (i) to file and prove a claim for the whole amount of principal
       (or portion thereof determined pursuant to Section 301(16) to be
       provable in bankruptcy) (and premium, if any) and interest owing and
       unpaid in respect of the Securities and to file such other papers or
       documents as may be necessary and advisable in order to have the claims
       of the Trustee (including any claim for the reasonable compensation,
       expenses, disbursements and advances of the Trustee, its agents and
       counsel and all other amounts due the Trustee under Section 607) and of
       the Securityholders allowed in such judicial proceeding, and

                                                                              58


              (ii) to collect and receive any moneys or other property payable
       or deliverable on any such claims and to distribute the same;

and any receiver, assignee, trustee, liquidator, sequestrator (or other similar
official) in any such judicial proceeding is hereby authorized by each
Securityholder to make such payment to the Trustee and in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 607.

              Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Securityholder in any such proceeding.

              Section 505.  Trustee May Enforce Claims Without Possession of
Securities.  All rights of action and claims under this Indenture or the
Securities of any series may be prosecuted and enforced by the Trustee without
the possession of any of the Securities of such series or the production
thereof in any proceeding relating thereto, and any such proceeding instituted
by the Trustee shall be brought in its own name as trustee of an express trust,
and any recovery of judgment shall, after provision for the payment of the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agent and counsel and any other amounts due the Trustee under Section 607,
be for the ratable benefit of the Holders of the Securities of the series in
respect of which such judgment has been recovered.

              Section 506.  Application of Money Collected.  Any money
collected by the Trustee with respect to a series of Securities pursuant to
this Article shall be applied in the following order, at the date or dates
fixed by the Trustee





<PAGE>   68
                                                                              59

and, in case of the distribution of such money on account of principal (or
premium, if any) or interest, upon presentation of the Securities of such
series and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

              FIRST:  To the payment of all amounts due the Trustee under
Section 607.

              SECOND:  To the payment of the amounts then due and unpaid upon
the Securities of that series for principal (and premium, if any) and interest,
in respect of which or for the benefit of which such money has been collected,
ratably, without preference or priority of any kind, according to the amounts
due and payable on such Securities for principal (and premium, if any) and
interest, respectively.

              Section 507.  Limitation on Suits.  No Holder of any Security of
any series shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder, unless

              (1) such Holder has previously given written notice to the
       Trustee of a continuing Event of Default with respect to Securities of
       such series;

              (2) the Holders of not less than 25% in principal amount of the
       Outstanding Securities of such series shall have made written request to
       the Trustee to institute proceedings in respect of such Event of Default
       in its own name as Trustee hereunder;

              (3) such Holder or Holders have furnished to the Trustee
       reasonable indemnity against the costs, expenses and liabilities to be
       incurred in compliance with such request;

              (4) the Trustee for 60 consecutive days after its receipt of such
       notice, request and furnishing of indemnity has failed to institute any
       such proceeding; and





<PAGE>   69
                                                                              60


              (5) no direction inconsistent with such written request has been
       given to the Trustee during such 60-day period by the Holders of a
       majority in principal amount of the Outstanding Securities of such
       series;

it being understood and intended that no one or more Holders of Securities of
such series shall have any right in any manner whatever by virtue of, or by
availing of, any provision of this Indenture to affect, disturb or prejudice
the rights of any other Holders of Securities of such series, or to obtain or
to seek to obtain priority or preference over any other such Holders or to
enforce any right under this Indenture, except in the manner herein provided
and for the equal and proportionate benefit of all the Holders of all
Securities of such series.

              Section 508.  Unconditional Right of Securityholders To Receive
Principal, Premium and Interest.  Notwithstanding any other provisions in this
Indenture, the Holder of any Security shall have the right, which is absolute
and unconditional, to receive payment of the principal of (and premium, if any)
and (subject to Section 307) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption or
repayment, on the Redemption Date or Repayment Date, as the case may be) and to
institute suit for the enforcement of any such payment, and such right shall
not be impaired without the consent of such Holder.

              Section 509.  Restoration of Rights and Remedies.  If the Trustee
or any Securityholder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, then and in every such case the Company, the Trustee
and the Securityholders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Trustee and the Securityholders shall
continue as though no such proceeding had been instituted.

              Section 510.  Rights and Remedies Cumulative.  No right or remedy
herein conferred upon or reserved to the Trustee or to the Securityholders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at
law or in equity or otherwise.  The assertion or employment of any right or
remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

              Section 511.  Delay or Omission Not Waiver.  No delay or omission
of the Trustee or of any Holder of any Security to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to the
Securityholders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Securityholders, as the case may be.

              Section 512.  Control by Securityholders.  The Holders of a
majority in principal amount of the Outstanding Securities of any series shall
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee with respect to the Securities of such series,
provided that

              (1) the Trustee shall have the right to decline to follow any
       such direction if the Trustee, being advised by counsel, determines that
       the action so directed may not lawfully be taken or would conflict with
       this Indenture or if the Trustee in good faith shall, by a Responsible
       Officer, determine that the proceedings so directed would involve it in
       personal liability or be unjustly prejudicial to the Holders not taking
       part in such direction, and

                                                                              62

              (2) the Trustee may take any other action deemed proper by the
       Trustee which is not inconsistent with such direction.

              Section 513.  Waiver of Past Defaults.  The Holders of not less
than a majority in principal amount of the Outstanding Securities of any series
may on behalf of the Holders of all the Securities of such series waive any
past default hereunder with respect to such series and its consequences, except
a default not theretofore cured

              (1) in the payment of the principal of (or premium, if any) or
       interest on any Security of such series, or in the payment of any
       sinking or purchase fund or analogous obligation with respect to the
       Securities of such series, or

              (2) in respect of a covenant or provision hereof which under
       Article Nine cannot be modified or amended without the consent of the
       Holder of each Outstanding Security of such series.

              Upon any such waiver, such default shall cease to exist, and any
Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.

              Section 514.  Undertaking for Costs.  All parties to this
Indenture agree, and each Holder of any Security by his acceptance thereof
shall be deemed to have agreed, that any court may in its discretion require,
in any suit for the enforcement of any right or remedy under this Indenture, or
in any suit against the Trustee for any action taken or omitted by it as
Trustee, the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, having due regard to the merits and good faith of the
claims or defenses made by such party litigant; but the provisions of this
Section shall not apply to any suit instituted by the Trustee, to

                                                                              63

any suit instituted by any Securityholder, or group of Securityholders, holding
in the aggregate more than 10% in principal amount of the Outstanding
Securities of any series to which the suit relates, or to any suit instituted
by any Securityholder for the enforcement of the payment of the principal of
(or premium, if any) or interest on any Security on or after the respective
Stated Maturities expressed in such Security (or, in the case of redemption or
repayment, on or after the Redemption Date or Repayment Date, as the case may
be).

              Section 515.  Waiver of Stay or Extension Laws.  The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance
of this Indenture; and the Company (to the extent that it may lawfully do so)
hereby expressly waives all benefit or advantage of any such law, and covenants
that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.


                                  ARTICLE SIX

                                  The Trustee

              Section 601.  Certain Duties and Responsibilities.  (a)  Except
during the continuance of an Event of Default with respect to any series of
Securities,

              (1) the Trustee undertakes to perform such duties and only such
       duties as are specifically set forth in this Indenture with respect to
       the Securities of such series, and no implied covenants or obligations
       shall be read into this Indenture against the Trustee; and

              (2) in the absence of bad faith on its part, the Trustee may,
       with respect to Securities of such series,





<PAGE>   73
                                                                              64

       conclusively rely, as to the truth of the statements and the correctness
       of the opinions expressed therein, upon certificates or opinions
       furnished to the Trustee and conforming to the requirements of this
       Indenture; but in the case of any such certificates or opinions which by
       any provision hereof are specifically required to be furnished to the
       Trustee, the Trustee shall be under a duty to examine the same to
       determine whether or not they conform to the requirements of this
       Indenture.

              (b)  In case an Event of Default with respect to any series of
Securities has occurred and is continuing, the Trustee shall exercise with
respect to the Securities of such series such of the rights and powers vested
in it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs.

              (c)  No provision of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that

              (1) this Subsection shall not be construed to limit the effect of
       Subsection (a) of this Section;

              (2) the Trustee shall not be liable for any error of judgment
       made in good faith by a Responsible Officer, unless it shall be proved
       that the Trustee was negligent in ascertaining the pertinent facts;

              (3) the Trustee shall not be liable with respect to any action
       taken or omitted to be taken by it in good faith in accordance with the
       direction of the Holders of a majority in principal amount of the
       Outstanding Securities of any series relating to the time, method and
       place of conducting any proceeding for any remedy available to the
       Trustee, or exercising any trust or power conferred upon the Trustee,
       under this Indenture with respect to the Securities of such series; and





<PAGE>   74
                                                                              65


              (4) no provision of this Indenture shall require the Trustee to
       expend or risk its own funds or otherwise incur any financial liability
       in the performance of any of its duties hereunder, or in the exercise of
       any of its rights or powers, if it shall have reasonable grounds for
       believing that repayment of such funds or adequate indemnity against
       such risk or liability is not reasonably assured to it.

              (d)  Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

              Section 602.  Notice of Defaults.  Within 90 days after the
occurrence of any default hereunder with respect to Securities of any series,
the Trustee shall transmit by mail to all Securityholders of such series, as
their names and addresses appear in the Security Register, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in
the payment of the principal of (or premium, if any) or interest on any
Security of such series or in the payment of any sinking or purchase fund
installment or analogous obligation with respect to Securities of such series,
the Trustee shall be protected in withholding such notice if and so long as the
board of directors, the executive committee or a trust committee of directors
and/or Responsible Officers of the Trustee in good faith determine that the
withholding of such notice is in the interests of the Securityholders of such
series; and provided, further, that in the case of any default of the character
specified in Section 501(5) with respect to Securities of such series no such
notice to Securityholders of such series shall be given until at least 30 days
after the occurrence thereof.  For the purpose of this Section, the term
"default", with respect to Securities of any series, means any event which is,
or after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

              Section 603.  Certain Rights of Trustee.  Except as otherwise
provided in Section 601:

              (a) the Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, certificate, statement, instrument,

other paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties;

              (b) any request or direction of the Company mentioned herein
shall be sufficiently evidenced by a Company Request or Company Order and any
resolution of the Board of Directors may be sufficiently evidenced by a Board
Resolution;

              (c) whenever in the administration of this Indenture the Trustee
shall deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its
part, rely upon an Officers' Certificate;

              (d) the Trustee may consult with counsel and the written advice
of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or
omitted by it hereunder in good faith and in reliance thereon;

              (e) the Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction
of any of the Securityholders pursuant to this Indenture, unless such
Securityholders shall have furnished to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred
by it in compliance with such request or direction;

              (f) the Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,





<PAGE>   76
                                                                              67

debenture or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney;

              (g) the Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder;

              (h) the Trustee shall not be charged with knowledge of any
default (as defined in Section 602) or Event of Default with respect to the
Securities of any series for which it is acting as Trustee unless either (1) a
Responsible Officer of the Trustee assigned to the Corporate Trust Department
of the Trustee (or any successor division or department of the Trustee) shall
have actual knowledge of such default or Event of Default or (2) written notice
of such default or Event of Default shall have been given to the Trustee by the
Company or any other obligor on such Securities or by any Holder of such
Securities; and

              (i) the Trustee shall not be liable for any action taken,
suffered or omitted by it in good faith and believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture.

              Section 604.  Not Responsible for Recitals or Issuance of
Securities.  The recitals contained herein and in the Securities, except the
certificates of authentication, shall be taken as the statements of the
Company, and the Trustee assumes no responsibility for their correctness.  The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities.  The Trustee shall not be accountable for the
use or application by the Company of Securities or the proceeds thereof.





<PAGE>   77
                                                                              68

              Section 605.  May Hold Securities.  The Trustee, any
Authenticating Agent, any Paying Agent, the Security Registrar or any other
agent of the Trustee, in its individual or any other capacity, may become the
owner or pledgee of Securities and, subject to Sections 608 and 613, may
otherwise deal with the Company with the same rights it would have if it were
not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such
other agent.

              Section 606.  Money Held in Trust.  Subject to the provisions of
Section 1003 hereof, all moneys in any currency or composite currency received
by the Trustee shall, until used or applied as herein provided, be held in
trust for the purposes for which they were received, but need not be segregated
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed by the Trustee in writing with the Company.

              Section 607.  Compensation and Reimbursement.  The Company agrees

              (1) to pay to the Trustee from time to time reasonable
       compensation for all services rendered by it hereunder (which
       compensation shall not be limited by any provision of law in regard to
       the compensation of a trustee of an express trust);

              (2) except as otherwise expressly provided herein, to reimburse
       the Trustee upon its request for all reasonable expenses, disbursements
       and advances incurred or made by the Trustee in accordance with any
       provision of this Indenture (including the reasonable compensation and
       the expenses and disbursements of its agents and counsel), except any
       such expense, disbursement or advance as may be attributable to its
       negligence or bad faith; and

              (3) to indemnify the Trustee for, and to hold it harmless
       against, any loss, liability or expense incurred without negligence or
       bad faith on its part, arising out of or in connection with the
       acceptance or





<PAGE>   78
                                                                              69

       administration of this trust, including the costs and expenses of
       defending itself against any claim or liability in connection with the
       exercise or performance of any of its powers or duties hereunder.

              As security for the performance of the obligations of the Company
under this Section the Trustee shall have a Lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of (and premium, if any) or interest
on particular Securities.

              When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(6) or (7), the
expenses and the compensation for the services are intended to constitute
expenses of administration under any bankruptcy law.

              The Company's obligations under this Section 607 and any Lien
arising hereunder shall survive the resignation or removal of any Trustee, the
discharge of the Company's obligations pursuant to Article Four of this
Indenture and/or the termination of this Indenture.

              Section 608.  Disqualification; Conflicting Interests.  The
Trustee for the Securities of any series issued hereunder shall be subject to
the provisions of Section 310(b) of the Trust Indenture Act during the period
of time provided for therein.  In determining whether the Trustee has a
conflicting interest as defined in Section 310(b) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded this
Indenture with respect to Securities of any particular series of Securities
other than that series.  Nothing herein shall prevent the Trustee from filing
with the Commission the application referred to in the second to last paragraph
of Section 310(b) of the Trust Indenture Act.

              Section 609.  Corporate Trustee Required; Eligibility.  There
shall at all times be a Trustee hereunder





<PAGE>   79
                                                                              70

with respect to each series of Securities, which shall be either

              (i) a corporation organized and doing business under the laws of
       the United States of America or of any State, authorized under such laws
       to exercise corporate trust powers and subject to supervision or
       examination by Federal or State authority, or

              (ii) a corporation or other Person organized and doing business
       under the laws of a foreign government that is permitted to act as
       Trustee pursuant to a rule, regulation or order of the Commission,
       authorized under such laws to exercise corporate trust powers, and
       subject to supervision or examination by authority of such foreign
       government or a political subdivision thereof substantially equivalent
       to supervision or examination applicable to United States institutional
       trustees,

in either case having a combined capital and surplus of at least $50,000,000.
If such corporation publishes reports of condition at least annually, pursuant
to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.
Neither the Company nor any Person directly or indirectly controlling,
controlled by, or under common control with the Company shall serve as trustee
for the Securities of any series issued hereunder.  If at any time the Trustee
with respect to any series of Securities shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect specified in Section 610.

              Section 610.  Resignation and Removal; Appointment of Successor.
(a)  No resignation or removal of the Trustee and no appointment of a successor
Trustee pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 611.





<PAGE>   80
                                                                              71


              (b)  The Trustee may resign with respect to any series of
Securities at any time by giving written notice thereof to the Company.  If an
instrument of acceptance by a successor Trustee shall not have been delivered
to the Trustee within 30 days after the giving of such notice of resignation,
the resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

              (c)  The Trustee may be removed with respect to any series of
Securities at any time by Act of the Holders of a majority in principal amount
of the Outstanding Securities of that series, delivered to the Trustee and to
the Company.

              (d)  If at any time:

              (1) the Trustee shall fail to comply with Section 310(b) of the
       Trust Indenture Act pursuant to Section 608 with respect to any series
       of Securities after written request therefor by the Company or by any
       Securityholder who has been a bona fide Holder of a Security of that
       series for at least six months, unless the Trustee's duty to resign is
       stayed in accordance with the provisions of Section 310(b) of the Trust
       Indenture Act, or

              (2) the Trustee shall cease to be eligible under Section 609 with
       respect to any series of Securities and shall fail to resign after
       written request therefor by the Company or by any such Securityholder,
       or

              (3) the Trustee shall become incapable of acting with respect to
       any series of Securities, or

              (4) the Trustee shall be adjudged a bankrupt or insolvent or a
       receiver of the Trustee or of its property shall be appointed or any
       public officer shall take charge or control of the Trustee or of its
       property or affairs for the purpose of rehabilitation, conservation or
       liquidation,





<PAGE>   81
                                                                              72

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, with respect to the series, or in the case of Clause (4), with respect
to all series, or (ii) subject to Section 514, any Securityholder who has been
a bona fide Holder of a Security of such series for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor Trustee with respect to the series, or, in the case of Clause (4),
with respect to all series.

              (e)  If the Trustee shall resign, be removed or become incapable
of acting with respect to any series of securities, or if a vacancy shall occur
in the office of the Trustee with respect to any series of Securities for any
cause, the Company, by a Board Resolution, shall promptly appoint a successor
Trustee for that series of Securities.  If, within one year after such
resignation, removal or incapacity, or the occurrence of such vacancy, a
successor Trustee with respect to such series of Securities shall be appointed
by Act of the Holders of a majority in principal amount of the outstanding
Securities of such series delivered to the Company and the retiring Trustee,
the successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee with respect to such series and
supersede the successor Trustee appointed by the Company with respect to such
series.  If no successor Trustee with respect to such series shall have been so
appointed by the Company or the Securityholders of such series and accepted
appointment in the manner hereinafter provided, subject to Section 514, any
Securityholder who has been a bona fide Holder of a Security of that series for
at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee with respect to such series.

              (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to any series and each appointment of a
successor Trustee with respect to any series by mailing written notice of such





<PAGE>   82
                                                                              73

event by first-class mail, postage prepaid, to the Holders of Securities of
that series as their names and addresses appear in the Security Register.  Each
notice shall include the name of the successor Trustee and the address of its
principal Corporate Trust Office.

              Section 611.  Acceptance of Appointment by Successor.  Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Company and to the predecessor Trustee an instrument accepting such
appointment, and thereupon the resignation or removal of the predecessor
Trustee shall become effective with respect to any series as to which it is
resigning or being removed as Trustee, and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the predecessor Trustee with respect to any such
series; but, on request of the Company or the successor Trustee, such
predecessor Trustee shall, upon payment of its reasonable charges, if any,
execute and deliver an instrument transferring to such successor Trustee all
the rights, powers and trusts of the predecessor Trustee, and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such predecessor Trustee hereunder with respect to all or any such
series, subject nevertheless to its Lien, if any, provided for in Section 607.
Upon request of any such successor Trustee, the Company shall execute any and
all instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

              In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
predecessor Trustee and each successor Trustee with respect to the Securities
of any applicable series shall execute and deliver an indenture supplemental
hereto which shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
predecessor Trustee with respect to the Securities of any series as to which
the predecessor Trustee is not being succeeded shall continue to be vested in
the predecessor Trustee, and shall

                                                                              74

add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust and that each such Trustee shall be Trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee.

              No successor Trustee with respect to any series of Securities
shall accept its appointment unless at the time of such acceptance such
successor Trustee shall be qualified and eligible with respect to that series
under this Article.

              Section 612.  Merger, Conversion, Consolidation or Succession to
Business.  Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

              Section 613.  Preferential Collection of Claims Against Company.
(a)  Subject to Subsection (b) of this Section, if the Trustee shall be or
shall become a creditor, directly or indirectly, secured or unsecured, of the
Company within three months prior to a default, as defined in Subsection (c) of
this Section, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of





<PAGE>   84
                                                                              75

the Securities and the holders of other indenture securities (as defined in
Subsection (c) of this Section):

              (1) an amount equal to any and all reduction in the amount due
       and owing upon any claim as such creditor in respect of principal or
       interest, effected after the beginning of such three-month period and
       valid as against the Company and its other creditors, except any such
       reduction resulting from the receipt or disposition of any property
       described in paragraph (2) of this Subsection, or from the exercise of
       any right of set-off which the Trustee could have exercised if a
       petition in bankruptcy had been filed by or against the Company upon the
       date of such default; and

              (2) all property received by the Trustee in respect of any claim
       as such creditor, either as security therefor, or in satisfaction or
       composition thereof, or otherwise, after the beginning of such three-
       month period, or an amount equal to the proceeds of any such property,
       if disposed of, subject, however, to the rights, if any, of the Company
       and its other creditors in such property or such proceeds.

Nothing herein contained, however, shall affect the right of the Trustee

              (A) to retain for its own account (i) payments made on account of
       any such claim by any Person (other than the Company) who is liable
       thereon, and (ii) the proceeds of the bona fide sale of any such claim
       by the Trustee to a third Person, and (iii) distributions made in cash,
       securities or other property in respect of claims filed against the
       Company in bankruptcy or receivership or in proceedings for
       reorganization pursuant to the Federal Bankruptcy Act or applicable
       State law;

              (B) to realize, for its own account, upon any property held by it
       as security for any such claim, if such property was so held prior to
       the beginning of such three-month period;





<PAGE>   85
                                                                              76


              (C) to realize, for its own account, but only to the extent of
       the claim hereinafter mentioned, upon any property held by it as
       security for any such claim, if such claim was created after the
       beginning of such three-month period and such property was received as
       security therefor simultaneously with the creation thereof, and if the
       Trustee shall sustain the burden of proving that at the time such
       property was so received the Trustee had no reasonable cause to believe
       that a default as defined in Subsection (c) of this Section would occur
       within three months; or

              (D) to receive payment on any claim referred to in paragraph (B)
       or (C) or against the release of any property held as security for such
       claim as provided in paragraph (B) or (C), as the case may be, to the
       extent of the fair value of such property.

              For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such three-month period for property held as
security at the time of such substitution shall, to the extent of the fair
value of the property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such paragraphs is
created in renewal of or in substitution for or for the purpose of repaying or
refunding any pre-existing claim of the Trustee as such creditor, such claim
shall have the same status as such pre-existing claim.

              If the Trustee shall be required to account, the funds and
property held in such special account and the proceeds thereof shall be
apportioned between the Trustee, the Securityholders and the holders of other
indenture securities in such manner that the Trustee, the Securityholders and
the holders of other indenture securities realize, as a result of payments from
such special account and payments of dividends on claims filed against the
Company, in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Act or applicable State law, the same
percentage of their respective claims, figured before crediting to the claim of
the Trustee anything on account of the receipt by it from





<PAGE>   86
                                                                              77

the Company of the funds and property in such special account and before
crediting to the respective claims of the Trustee and the Securityholders and
the holders of other indenture securities dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Act or applicable State law, but after
crediting thereon receipts on account of the indebtedness represented by their
respective claims from all sources other than from such dividends and from the
funds and property so held in such special account.  As used in this paragraph,
with respect to any claim, the term "dividends" shall include any distribution
with respect to such claim, in bankruptcy or receivership or proceedings for
reorganization pursuant to the Federal Bankruptcy Act or applicable State law,
whether such distribution is made in cash, securities, or other property, but
shall not include any such distribution with respect to the secured portion, if
any, of such claim.  The court in which such bankruptcy, receivership or
proceedings for reorganization is pending shall have jurisdiction (i) to
apportion between the Trustee and the Securityholders and the holders of other
indenture securities, in accordance with the provisions of this paragraph, the
funds and property held in such special account and proceeds thereof, or (ii)
in lieu of such apportionment, in whole or in part, to give to the provisions
of this paragraph due consideration in determining the fairness of the
distributions to be made to the Trustee and the Securityholders and the holders
of other indenture securities with respect to their respective claims, in which
event it shall not be necessary to liquidate or to appraise the value of any
securities or other property held in such special account or as security for
any such claim, or to make a specific allocation of such distributions as
between the secured and unsecured portions of such claims, or otherwise to
apply the provisions of this paragraph as a mathematical formula.

              Any Trustee which has resigned or been removed after the
beginning of such three-month period shall be subject to the provisions of this
Subsection as though such resignation or removal had not occurred.  If any
Trustee has resigned or been removed prior to the beginning of such





<PAGE>   87
                                                                              78

three-month period, it shall be subject to the provisions of this Subsection if
and only if the following conditions exist:

              (i) the receipt of property or reduction of claim, which would
       have given rise to the obligation to account, if such Trustee had
       continued as Trustee, occurred after the beginning of such three-month
       period; and

              (ii) such receipt of property or reduction of claim occurred
       within three months after such resignation or removal.

              (b)  There shall be excluded from the operation of Subsection (a)
of this Section a creditor relationship arising from

              (1) the ownership or acquisition of securities issued under any
       indenture, or any security or securities having a maturity of one year
       or more at the time of acquisition by the Trustee;

              (2) advances authorized by a receivership or bankruptcy court of
       competent jurisdiction, or by this Indenture, for the purpose of
       preserving any property which shall at any time be subject to the Lien
       of this Indenture or of discharging tax liens or other prior liens or
       encumbrances thereon, if notice of such advances and of the
       circumstances surrounding the making thereof is given to the
       Securityholders at the time and in the manner provided in this
       Indenture;

              (3) disbursements made in the ordinary course of business in the
       capacity of trustee under an indenture, transfer agent, registrar,
       custodian, paying agent, fiscal agent or depository, or other similar
       capacity;

              (4) an indebtedness created as a result of services rendered or
       premises rented; or an indebtedness created as a result of goods or
       securities





<PAGE>   88
                                                                              79

       sold in a cash transaction as defined in Subsection (c) of this Section;

              (5) the ownership of stock or of other securities of a
       corporation organized under the provisions of Section 25(a) of the
       Federal Reserve Act, as amended, which is directly or indirectly a
       creditor of the Company; or

              (6) the acquisition, ownership, acceptance or negotiation of any
       drafts, bills of exchange, acceptances or obligations which fall within
       the classification of self-liquidating paper as defined in Subsection
       (c) of this Section.

              (c)  For the purposes of this Section only:

              (1)  The term "default" means any failure to make payment in full
       of the principal of or interest on any of the Securities or upon the
       other indenture securities when and as such principal or interest
       becomes due and payable.

              (2)  The term "other indenture securities" means securities upon
       which the Company is an obligor outstanding under any other indenture
       (i) under which the Trustee is also trustee, (ii) which contains
       provisions substantially similar to the provisions of this Section, and
       (iii) under which a default exists at the time of the apportionment of
       the funds and property held in such special account.

              (3)  The term "cash transaction" means any transaction in which
       full payment for goods or securities sold is made within seven days
       after delivery of the goods or securities in currency or in checks or
       other orders drawn upon banks or bankers and payable upon demand.

              (4)  The term "self-liquidating paper" means any draft, bill of
       exchange, acceptance or obligation which is made, drawn, negotiated or
       incurred by the Company





<PAGE>   89
                                                                              80

       for the purpose of financing the purchase, processing, manufacturing,
       shipment, storage or sale of goods, wares or merchandise and which is
       secured by documents evidencing title to, possession of, or a lien upon,
       the goods, wares or merchandise or the receivables or proceeds arising
       from the sale of the goods, wares or merchandise previously constituting
       the security, provided the security is received by the Trustee
       simultaneously with the creation of the creditor relationship with the
       Company arising from the making, drawing, negotiating or incurring of
       the draft, bill of exchange, acceptance or obligation.

              (5)  The term, "Company" means any obligor upon the Securities.

              Section 614.  Appointment of Authenticating Agent.  At any time
when any of the Securities remain Outstanding the Trustee, with the approval of
the Company, may appoint an Authenticating Agent or Agents with respect to one
or more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon original
issuance, exchange, registration of transfer or partial redemption thereof or
pursuant to Section 306, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.  Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as an
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and, if other than the Company itself, subject to supervision or
examination by Federal or State authority.  If such





<PAGE>   90
                                                                              81

Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

              Any corporation into which an Authenticating Agent may be merged
or converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

              An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and, if other than the Company, to the Company.
The Trustee may at any time terminate the agency of an Authenticating Agent by
giving written notice thereof to such Authenticating Agent and, if other than
the Company, to the Company.  Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall
cease to be eligible in accordance with the provisions of this Section, the
Trustee, with the approval of the Company, may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Securities of the series with respect to which such Authenticating
Agent will serve, as their names and addresses appear in the Security Register.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested





<PAGE>   91
                                                                              82

with all the rights, powers and duties of its predecessor hereunder, with like
effect as if originally named as an Authenticating Agent.  No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section.

              The Trustee agrees to pay to each Authenticating Agent from time
to time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

              If an appointment with respect to one or more series is made
pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to the Trustee's certificate of authentication, an
alternate certificate of authentication in the following form:

              This is one of the Securities of the series designated therein
referred to in the within-mentioned Indenture.

                                 ARTICLE SEVEN

                     Securityholders' Lists and Reports by
                              Trustee and Company

              Section 701.  Company To Furnish Trustee Names and Addresses of
Securityholders.  The Company will furnish or cause to be furnished to the
Trustee

              (1) semiannually, not more than 15 days after December 15 and
       June 15 in each year in such form as the Trustee may reasonably require,
       a list of the names and addresses of the Holders of Securities of each
       series as of such December 15 and June 15, as applicable, and

              (2) at such other times as the Trustee may request in writing,
       within 30 days after the receipt by the Company of any such request, a
       list of similar form and content as of a date not more than 15 days
       prior to the time such list is furnished;

provided, however, that if and so long as the Trustee shall be the Security
Registrar for Securities of a series, no such list need be furnished with
respect to such series of Securities.

              Section 702.  Preservation of Information; Communications to
Securityholders.  (a)  The Trustee shall preserve, in as current a form as is
reasonably practicable, the names and addresses of Holders of Securities
contained in the most recent list furnished to the Trustee as provided in
Section 701 and the names and addresses of Holders of Securities received by
the Trustee in its capacity as Security Registrar, if so acting.  The Trustee
may destroy any list furnished to it as provided in Section 701 upon receipt of
a new list so furnished.

              (b)  If three or more Holders of Securities of any series
(hereinafter referred to as "applicants") apply in writing to the Trustee, and
furnish to the Trustee reason-able proof that each such applicant has owned a
Security of





<PAGE>   93
                                                                              84

such series for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other Holders of Securities of such series or with the Holders
of all Securities with respect to their rights under this Indenture or under
such Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Trustee
shall, within five Business Days after the receipt of such application, at its
election, either

              (i) afford such applicants access to the information preserved at
       the time by the Trustee in accordance with Section 702(a), or

              (ii) inform such applicants as to the approximate number of
       Holders of Securities of such series or all Securities, as the case may
       be, whose names and addresses appear in the information preserved at the
       time by the Trustee in accordance with Section 702(a), and as to the
       approximate cost of mailing to such Securityholders the form of proxy or
       other communication, if any, specified in such application.

              If the Trustee shall elect not to afford such applicants access
to such information, the Trustee shall, upon the written request of such
applicants, mail to each Holder of a Security of such series or to all
Securityholders, as the case may be, whose names and addresses appear in the
information preserved at the time by the Trustee in accordance with Section
702(a), a copy of the form of proxy or other communication which is specified
in such request, with reasonable promptness after a tender to the Trustee of
the material to be mailed and of payment, or provision for the payment, of the
reasonable expenses of mailing, unless, within five days after such tender, the
Trustee shall mail to such applicants and file with the Commission, together
with a copy of the material to be mailed, a written statement to the effect
that, in the opinion of the Trustee, such mailing would be contrary to the best
interests of the Holders of Securities of such series or all Securityholders,
as the case may be, or would





<PAGE>   94
                                                                              85

be in violation of applicable law.  Such written statement shall specify the
basis of such opinion.  If the Commission, after opportunity for a hearing upon
the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all Securityholders of such series or all
Securityholders, as the case may be, with reasonable promptness after the entry
of such order and the renewal of such tender; otherwise the Trustee shall be
relieved of any obligation or duty to such applicants respecting their
application.

              (c)  Every Holder of Securities, by receiving and holding the
same, agrees with the Company and the Trustee that neither the Company nor the
Trustee shall be held accountable by reason of the disclosure of any such
information as to the names and addresses of the Holders of Securities in
accordance with Section 702(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 702(b).

              Section 703.  Reports by Trustee.  (a)  The term "reporting date"
as used in this Section means May 15.  Within 60 days after the reporting date
in each year, beginning in 1998, the Trustee shall transmit by mail to all
Securityholders, as their names and addresses appear in the Security Register,
a brief report dated as of such reporting date with respect to any of the
following events which may have occurred during the twelve months preceding the
date of such report (but if no such event has occurred within such period, no
report need be transmitted):

              (1) any change to its eligibility under Section 609 and its
       qualifications under Section 608;





<PAGE>   95
                                                                              86

              (2) the creation of or any material change to a relationship
       specified in Section 310(b)(1) through Section 310(b)(10) of the Trust
       Indenture Act;

              (3) the character and amount of any advances (and if the Trustee

       made by the Trustee (as such) which remain unpaid on the date of such
       report, and for the reimbursement of which it claims or may claim a Lien
       or charge, prior to that of Securities of any series, on any property or
       funds held or collected by it as Trustee, except that the Trustee shall
       not be required (but may elect) to report such advances if such advances
       so remaining unpaid aggregate not more than 1/2 of 1% of the principal
       amount of the Securities of such series Outstanding on the date of such
       report;

              (4) any change to the amount, interest rate and maturity date of

       the Securities) to the Trustee in its individual capacity, on the date
       of such report, with a brief description of any property held as
       collateral security therefor, except an indebtedness based upon a
       creditor relationship arising in any manner described in Section
       613(b)(2), (3), (4), or (6);

       acts and which the Trustee has not previously reported; and

              (7) any action taken by the Trustee in the performance of its
       duties hereunder which it has not previously reported and which in its
       opinion materially affects the Securities, except action in respect of a
       default, notice of which has been or is to be withheld by the Trustee in
       accordance with Section 602.

              (b)  The Trustee shall transmit by mail to all Securityholders,
as their names and addresses appear in the Security Register, a brief report
with respect to the character and amount of any advances (and if the Trustee
elects so to state, the circumstances surrounding the making thereof) made by
the Trustee (as such) since the date of the last report transmitted pursuant to
Subsection (a) of this Section (or if no such report has yet been so
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a Lien or charge, prior to that
of the Securities of any series, on property or funds held or collected by it
as Trustee, and which it has not previously reported pursuant to this
Subsection, except that the Trustee shall not be required (but may elect) to
report such advances if such advances remaining unpaid at any time aggregate
10% or less of the principal amount of the Securities Outstanding of such
series at such time, such report to be transmitted within 90 days after such
time.

              (c)  A copy of each such report shall, at the time of such
transmission to Securityholders, be furnished to the Company and be filed by
the Trustee with each stock exchange upon which the Securities are listed, and
also with the Commission.  The Company will notify the Trustee when the
Securities are listed on any stock exchange.

              Section 704.  Reports by Company.  The Company shall file with
the Trustee, and transmit to Holders, such information, documents and other
reports, and such summaries thereof, as may be required pursuant to the Trust
Indenture Act at the times and in the manner provided pursuant to such Act;
provided that any such information, documents or reports required to be filed
with the Commission pursuant to Section 13 or 15(d) of the Securities Exchange
Act of 1934 shall be filed with the Trustee within 15 days after the same is so
required to be filed with the Commission.  The Company also shall comply with
the other provisions of Trust Indenture Act Section 314(a).

              (1) the corporation formed by such consolidation or into which
       the Company is merged or the Person which acquires or leases all or
       substantially all of the Company's property shall be organized and

              (1) to evidence the succession of another corporation or Person
       to the Company, and the assumption by any such successor of the
       covenants of the Company herein and in the Securities contained; or

              (2) to add to the covenants of the Company, or to surrender any

              (4) to add to this Indenture such provisions as may be expressly
       permitted by the TIA, excluding, however, the provisions referred to in
       Section 316(a)(2) of the TIA as in effect at the date as of which this
       instrument was executed or any corresponding provision in any similar
       federal statute hereafter enacted; or

affect the interest of the Holder of Securities of any series in any material
respect.

Securityholders.  With the consent of the Holders of not less than a majority

indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of the
Securities of each such series under this Indenture; provided, however, that no
such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby,

              (1) change the Maturity of the principal of, or the Stated
       Maturity of any premium on, or any installment of interest on, any
       Security, or reduce the principal amount thereof or the interest or any
       premium thereon, or change the method of computing the amount of
       principal thereof or interest thereon on any date or change any Place of
       Payment where, or the coin or currency in which, any Security or any
       premium or interest thereon is payable, or impair the right to institute
       suit for the enforcement of any such payment on or after the Maturity or
       the Stated Maturity, as the case may be, thereof (or, in the case of
       redemption or repayment, on or after the Redemption Date or the
       Repayment Date, as the case may be), or alter the provisions of this
       Indenture so as to affect adversely the terms, if any, of conversion of
       any Securities into other securities; or

              (2) reduce the percentage in principal amount of the Outstanding
       Securities of any series, the consent of whose Holders is required for
       any such supplemental indenture, or the consent of whose Holders is
       required for any waiver of compliance with certain provisions of this
       Indenture or certain defaults hereunder and their consequences, provided
       for in this Indenture; or

       Section 1009, except to increase any such percentage or to provide that
       certain other provisions of this Indenture cannot be modified or waived
       without the consent of the Holder of each Outstanding Security affected
       thereby; or

              (4) impair or adversely affect the right of any Holder to
       institute suit for the enforcement of any payment on, or with respect
       to, the Securities of any series on or after the Stated Maturity of such
       Securities (or in the case of redemption, on or after the Redemption
       Date).

              A supplemental indenture which changes or eliminates any covenant
or other provision of this Indenture which has expressly been included solely
for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights
under this Indenture of the Holders of Securities of any other series.

              It shall not be necessary for any Act of Securityholders under
this Section to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such Act shall approve the substance
thereof.

              Section 903.  Execution of Supplemental Indentures.  In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Section 601) shall be fully protected in relying upon, an Opinion
of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture.  The Trustee may, but shall not be
obligated to, enter into any such supplemental indenture which affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

              Section 904.  Effect of Supplemental Indentures.  Upon the
execution of any supplemental indenture under this Article, this Indenture
shall be modified in accordance therewith, and such supplemental indenture
shall form a part of this Indenture for all purposes; and every Holder of
Securities theretofore or thereafter authenticated and

supplemental indenture executed pursuant to this Article shall conform to the
requirements of the TIA as then in effect.

              Section 906.  Reference in Securities to Supplemental Indentures.
Securities authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for
in such supplemental indenture.   If the Company shall so determine, new
Securities so modified as to conform, in the opinion of the Trustee and the
Board of Directors, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities.

              Section 1001.  Payment of Principal, Premium and Interest.  With
respect to each series of Securities, the Company will duly and punctually pay
the principal of (and premium, if any) and interest on such Securities in
accordance with their terms and this Indenture, and will duly comply with all
the other terms, agreements and conditions contained in, or made in the
Indenture for the benefit of, the Securities of such series.

              Section 1002.  Maintenance of Office or Agency.  The Company will
maintain an office or agency in each Place of Payment where Securities may be
presented or surrendered for payment, where Securities may be surrendered for
registration of transfer or exchange, where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served and where
any Securities

                                                                              94

with conversion privileges may be presented and surrendered for conversion.
The Company will give prompt written notice to the Trustee of the location, and
of any change in the location, of such office or agency.  If at any time the
Company shall fail to maintain such office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Trustee,
and the Company hereby appoints the Trustee its agent to receive all such
presentations, surrenders, notices and demands.

              Unless otherwise set forth in, or pursuant to, a Board Resolution
or indenture supplemental hereto with respect to a series of Securities, the
Company hereby initially designates as the Place of Payment for each series of
Securities, the Borough of Manhattan, the City and State of New York, and
initially appoints the Trustee at its Corporate Trust Office as the Company's
office or agency for each such purpose in such city.

              Section 1003.  Money for Security Payments To Be Held in Trust.
If the Company shall at any time act as its own Paying Agent for any series of
Securities, it will, on or before each due date of the principal of (and
premium, if any) or interest on, any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
action or failure to act.

              Whenever the Company shall have one or more Paying Agents for any
series of Securities, it will, on or prior to each due date of the principal of
(and premium, if any) or interest on, any Securities of such series, deposit
with a Paying Agent a sum sufficient to pay such amount, such sum to be held as
provided by the Trust Indenture Act, and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.





<PAGE>   104
                                                                              95


              The Company will cause each Paying Agent other than the Trustee
for any series of Securities to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section, that such Paying Agent will

              (1) comply with the provisions of the Trust Indenture Act
       applicable to it as Paying Agent;

              (2) give the Trustee notice of any default by the Company (or any
       other obligor upon the Securities of such series) in the making of any
       payment of principal (and premium, if any) or interest on the Securities
       of such series; and

              (3) at any time during the continuance of any such default, upon
       the written request of the Trustee, forthwith pay to the Trustee all
       sums so held in trust by such Paying Agent.

              The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture with respect to any series of
Securities or for any other purpose, pay, or by Company Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent in respect of each and every series of Securities as to which it
seeks to discharge this Indenture or, if for any other purpose, all sums so
held in trust by the Company in respect of all Securities, such sums to be held
by the Trustee upon the same trusts as those upon which such sums were held by
the Company or such Paying Agent; and, upon such payment by any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability
with respect to such money.

              Any money deposited with the Trustee or any Paying Agent, or then
held by the Company, in trust for the payment of the principal of (and premium,
if any) or interest on any Security of any series and remaining unclaimed for
two years after such principal (and premium, if any) or interest has become due
and payable shall be paid to the Company on Company Request, or (if then held
by the Company) shall be





<PAGE>   105
                                                                              96

discharged from such trust; and the Holder of such Security shall thereafter,
as an unsecured general creditor, look only to the Company for payment thereof,
and all liability of the Trustee or such Paying Agent with respect to such
trust money, and all liability of the Company as trustee thereof, shall
thereupon cease.  The Trustee or such Paying Agent, before being required to
make any such repayment, may at the expense of the Company mail to the Holders
of the Securities as to which the money to be repaid was held in trust, as
their names and addresses appear in the Security Register, a notice that such
moneys remain unclaimed and that, after a date specified in the notice, which
shall not be less than 30 days from the date on which the notice was first
mailed to the Holders of the Securities as to which the money to be repaid was
held in trust, any unclaimed balance of such moneys then remaining will be paid
to the Company free of the trust formerly impressed upon it.

              Section 1004.  Statement as to Compliance.  The Company will
deliver to the Trustee, within 120 days after the end of each fiscal year, a
written statement signed by the principal executive officer, principal
financial officer or principal accounting officer of the Company stating that

              (1) a review of the activities of the Company during such year
       and of performance under this Indenture and under the terms of the
       Securities has been made under his supervision; and

              (2) to the best of his knowledge, based on such review, the
       Company has fulfilled all its obligations under this Indenture and has
       complied with all conditions and covenants on its part contained in this
       Indenture through such year, or, if there has been a default in the
       fulfillment of any such obligation, covenant or condition, specifying
       each such default known to him and the nature and status thereof.

              For the purpose of this Section 1004, default and compliance
shall be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

              Section 1005.  Legal Existence.  Subject to Article Eight the
Company will do or cause to be done all things necessary to preserve and keep
in full force and effect its legal existence.

              Section 1006.  Limitation on Subsidiary Debt and Preferred Stock.
The Company shall not permit any Subsidiary of the Company to Incur or suffer
to exist any Debt, except for Permitted Debt, or issue any Preferred Stock.

              Section 1007.  Limitation on Liens.  The Company shall not, and
shall not permit any Subsidiary of the Company, to Incur any Lien on property
or assets of the Company or such Subsidiary, to secure Debt without making, or
causing such Subsidiary to make, effective provision for securing the
Securities (and, if required by its governing instruments, any other Debt of
the Company or of such Subsidiary that is not subordinate to the Securities)
equally and ratably with such Debt as to such property for so long as such Debt
will be so secured or, in the event such Debt is Debt of the Company which is
subordinate in right of payment to the Securities, prior to such Debt as to
such property for so long as such Debt will be secured; provided, however, that
nothing contained in this covenant shall prevent, restrict or apply to, and
there shall be excluded from secured Debt in any computation under this
Section, Liens existing on the date of this Indenture or Permitted Liens.

              Section 1008.  Limitation on Sale and Leaseback Transactions.
The Company shall not, and shall not permit any Subsidiary of the Company to,
enter into any Sale and Leaseback Transaction (except for a period not
exceeding three years) unless the Company or such Subsidiary would be entitled
to Incur a Lien to secure Debt by reason of the provisions described in clauses
(i) through (xiii) of the definition of Permitted Liens in an amount equal to
the Attributable Value of such Sale and Leaseback Transaction without equally
and ratably securing the Securities.

              Section 1009.  Waiver of Certain Covenants.  The Company may omit
in respect of any series of Securities, in any particular instance, to comply
with any covenant or condition set forth in Sections 1006, 1007 or 1008 or set
forth in a Board Resolution or supplemental indenture with respect to the
Securities of such series, unless otherwise specified in such Board Resolution
or supplemental indenture, if before or after the time for such compliance the
Holders of at least a majority in principal amount of the Securities at the
time Outstanding of such series shall, by Act of such Securityholders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such covenant or condition shall remain in full
force and effect.  Nothing in this Section 1009 shall permit the waiver of
compliance with any covenant or condition set forth in such Board Resolution or
supplemental indenture which, if in the form of an indenture supplemental
hereto, would not be permitted by Section 902 without the consent of the Holder
of each Outstanding Security affected thereby.


                                 ARTICLE ELEVEN

                            Redemption of Securities

              Section 1101.  Applicability of Article.  The Company may reserve
the right to redeem and pay before Stated Maturity all or any part of the
Securities of any series, either by optional redemption, sinking or purchase
fund or analogous obligation or otherwise, by provision therefor in the form of
Security for such series established and approved pursuant to Section 202 and
on such terms as are specified in such form or in the indenture supplemental
hereto with respect to Securities of such series as provided in Section 301.
Redemption of Securities of any series shall be made in accordance with the
terms of such Securities and, to the extent that this Article does not

                                                                              99

conflict with such terms, the succeeding Sections of this Article.
Notwithstanding anything to the contrary in this Indenture, except in the case
of redemption pursuant to a sinking fund, the Trustee shall not make any
payment in connection with the redemption of Securities until the close of
business on the Redemption Date.

              Section 1102.  Election To Redeem; Notice to Trustee.  The
election of the Company to redeem any Securities redeemable at the election of
the Company shall be evidenced by, or pursuant to authority granted by, a Board
Resolution.  In case of any redemption at the election of the Company of less
than all of the Securities of any series, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date and of the principal amount of Securities of such series and the Tranche
(as defined in Section 1103) to be redeemed.

              In the case of any redemption of Securities (i) prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, or (ii) pursuant to an election of
the Company which is subject to a condition specified in the terms of such
Securities, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

              Section 1103.  Selection by Trustee of Securities To Be Redeemed.
If less than all the Securities of like tenor and terms of any series (a
"Tranche") are to be redeemed, the particular Securities to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee,
from the Outstanding Securities of such Tranche not previously called for
redemption, by lot or by such other method as the Trustee shall deem fair and
appropriate and which may include provision for the selection for redemption of
portions of the principal of Securities of such Tranche of a denomination
larger than the minimum authorized denomination for Securities of that series.
Unless otherwise provided in the terms of a





<PAGE>   109
                                                                             100

particular series of Securities, the portions of the principal of Securities so
selected for partial redemption shall be equal to the minimum authorized
denomination of the Securities of such series, or an integral multiple thereof,
and the principal amount which remains outstanding shall not be less than the
minimum authorized denomination for Securities of such series.  If less than
all the Securities of unlike tenor and terms of a series are to be redeemed,
the particular Tranche of Securities to be redeemed shall be selected by the
Company.

              If any convertible Security selected for partial redemption is
converted in part before the termination of the conversion right with respect
to the portion of the Security so selected, the converted portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption.

              Upon any redemption of fewer than all the Securities of a series
or Tranche, the Company and the Trustee may treat as Outstanding any Securities
surrendered for conversion during the period of fifteen days next preceding the
mailing of a notice of redemption, and need not treat as Outstanding any
Security authenticated and delivered during such period in exchange for the
unconverted portion of any Security converted in part during such period.

              The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Security selected
for partial redemption, the principal amount thereof to be redeemed.

              Securities shall be excluded from eligibility for selection for
redemption if they are identified by registration and certificate number in a
written statement signed by an authorized officer of the Company and delivered
to the Trustee at least 60 days prior to the Redemption Date as being owned of
record and beneficially by, and not pledged or hypothecated by either, (a) the
Company or (b) an entity specifically identified in such written statement as
being an Affiliate of the Company.

                                                                             101

              For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal of such Security which has been or is to be redeemed.

              Section 1104.  Notice of Redemption.  Notice of redemption shall
be given by first-class mail, postage prepaid, mailed not less than 30 (or 15
if so provided in the Board Resolution establishing the relevant series) nor
more than 60 days prior to the Redemption Date, to each holder of Securities to
be redeemed, at his address appearing in the Security Register.

              All notices of redemption shall state:

              (1) the Redemption Date;

              (2) the Redemption Price;

              (3) if less than all Outstanding Securities of any series are to
       be redeemed, the identification (and, in the case of partial redemption,
       the respective principal amounts) of the Securities to be redeemed;

              (4) that on the Redemption Date the Redemption Price will become
       due and payable upon each such Security, and that interest, if any,
       thereon shall cease to accrue from and after said date;

              (5) the place where such Securities are to be surrendered for
       payment of the Redemption Price, which shall be the office or agency of
       the Company in the Place of Payment;

              (6) that the redemption is on account of a sinking or purchase
       fund, or other analogous obligation, if that be the case; and

              (7) if such Securities are convertible into other securities, the
       conversion price and the date on which





<PAGE>   111
                                                                             102

       the right to convert such Securities into other securities will
       terminate.

              Notice of redemption of Securities to be redeemed at the election
of the Company shall be given by the Company or, at the Company's request, by
the Trustee in the name and at the expense of the Company.

              Section 1105.  Deposit of Redemption Price.  On or prior to any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of all the Securities which are to be redeemed on that date.
If any Security to be redeemed is converted into other securities, any money so
deposited with the Trustee or a Paying Agent shall be paid to the Company upon
Company Request or, if then so segregated and held in trust by the Company,
shall be discharged from such trust.

              Section 1106.  Securities Payable on Redemption Date.  Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified and from and after such date (unless the Company shall
default in the payment of the Redemption Price) such Securities shall cease to
bear interest and any rights to convert such Securities shall terminate.  Upon
surrender of such Securities for redemption in accordance with the notice, such
Securities shall be paid by the Company at the Redemption Price.  Unless
otherwise provided with respect to such Securities pursuant to Section 301,
installments of interest the Stated Maturity of which is on or prior to the
Redemption Date shall be payable to the Holders of such Securities registered
as such on the relevant Regular Record Dates according to their terms and the
provisions of Section 307.

              If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid, bear
interest from the Redemption Date at





<PAGE>   112
                                                                             103

the rate borne by the Security, or as otherwise provided in such Security.

              Section 1107.  Securities Redeemed in Part.  Any Security which
is to be redeemed only in part shall be surrendered at the office or agency of
the Company in the Place of Payment with respect to that series (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee duly executed
by, the Holder thereof or his attorney duly authorized in writing) and the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and Stated Maturity and of like tenor and terms, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

              Section 1108.  Provisions with Respect to Any Sinking Funds.
Unless the form or terms of any series of Securities shall provide otherwise,
in lieu of making all or any part of any mandatory sinking fund payment with
respect to such series of Securities in cash, the Company may at its option (1)
deliver to the Trustee for cancelation any Securities of such series
theretofore acquired by the Company or converted by the Holder thereof into
other securities, or (2) receive credit for any Securities of such series (not
previously so credited) acquired by the Company (including by way of optional
redemption pursuant to the sinking fund or otherwise but not by way of
mandatory sinking fund redemption) or converted by the Holder thereof into
other securities and theretofore delivered to the Trustee for cancelation, and
if it does so then (i) Securities so delivered or credited shall be credited at
the applicable sinking fund Redemption Price with respect to Securities of such
series, and (ii) on or before the 60th day next preceding each sinking fund
Redemption Date with respect to such series of Securities, the Company will
deliver to the Trustee (A) an Officers' Certificate specifying the portions of
such sinking fund payment to be satisfied by payment of cash and by delivery or
credit of





<PAGE>   113
                                                                             104

Securities of such series acquired by the Company or converted by the Holder
thereof, and (B) such Securities, to the extent not previously surrendered.
Such Officers' Certificate shall also state the basis for such credit and that
the Securities for which the Company elects to receive credit have not been
previously so credited and were not acquired by the Company through operation
of the mandatory sinking fund, if any, provided with respect to such Securities
and shall also state that no Event of Default with respect to Securities of
such series has occurred and is continuing.  All Securities so delivered to the
Trustee shall be canceled by the Trustee and no Securities shall be
authenticated in lieu thereof.

              If the sinking fund payment or payments (mandatory or optional)
with respect to any series of Securities made in cash plus any unused balance
of any preceding sinking fund payments with respect to Securities of such
series made in cash shall exceed $50,000 (or a lesser sum if the Company shall
so request), unless otherwise provided by the terms of such series of
Securities, that cash shall be applied by the Trustee on the sinking fund
Redemption Date with respect to Securities of such series next following the
date of such payment to the redemption of Securities of such series at the
applicable sinking fund Redemption Price with respect to Securities of such
series, together with accrued interest, if any, to the date fixed for
redemption, with the effect provided in Section 1106.  The Trustee shall
select, in the manner provided in Section 1103, for redemption on such sinking
fund Redemption Date a sufficient principal amount of Securities of such series
to utilize that cash and shall thereupon cause notice of redemption of the
Securities of such series for the sinking fund to be given in the manner
provided in Section 1104 (and with the effect provided in Section 1106) for the
redemption of Securities in part at the option of the Company.  Any sinking
fund moneys not so applied or allocated by the Trustee to the redemption of
Securities of such series shall be added to the next cash sinking fund payment
with respect to Securities of such series received by the Trustee and, together
with such payment, shall be applied in accordance with the provisions of this
Section 1108.  Any and all sinking fund moneys with

                                                                             105

respect to Securities of any series held by the Trustee at the Maturity of
Securities of such series, and not held for the payment or redemption of
particular Securities of such series, shall be applied by the Trustee, together
with other moneys, if necessary, to be deposited sufficient for the purpose, to
the payment of the principal of the Securities of such series at Maturity.

              On or before each sinking fund Redemption Date provided with
respect to Securities of any series, the Company shall pay to the Trustee in
cash a sum equal to all accrued interest, if any, to the date fixed for
redemption on Securities to be redeemed on such sinking fund Redemption Date
pursuant to this Section 1108.



              IN WITNESS WHEREOF, the parties hereto have caused this Indenture
to be duly executed as of the day and year first above written.

       Re:  Form S-3 Registration Statement

Ladies & Gentlemen:

        We have acted as counsel to TCA Cable TV, Inc. (the "Company") in
connection with the preparation of the registration statement on Form S-3 (the
"Registration Statement") under the Securities Act of 1933, as amended (the
"Securities Act"), relating to the issuance of an aggregate of up to
$300,000,000 of debt securities (the "Debt Securities") of the Company pursuant
to the indenture in the form filed as Exhibit 4(a) to the Registration
Statement (the "Indenture") among the Company and Texas Commerce Bank National
Association, as Trustee.

        We have examined such corporate records and documents and other matters
as we have deemed necessary in order to render this opinion.  In our
examination, we have assumed a genuineness of all signatures, the authenticity
of all documents submitted to us as originals and the conformity to authentic
original documents of all documents submitted to us as copies.  Based upon the
foregoing, and subject to the limitations set forth below, it is our opinion
that under current law when the Debt Securities have been duly executed and,
authenticated and delivered in accordance with the terms of the Indenture and
delivered to the purchasers thereof against payment therefore in accordance
with the procedures described in the Registration Statement, such Debt
Securities will constitute the legal and binding obligations of the Company.

        Our opinions herein are limited solely to the laws of the United States
of America and the State of Texas, in each case to the extent applicable, and
we express no opinions herein concerning the laws of any other jurisdiction.

        Our opinions herein are subject to the effect of any applicable
bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization or
consumer law effecting creditors' rights or debtors' obligations generally and
to general equity principles, including, without limitation, concepts of
materiality, reasonableness, good faith, fair dealing, and other similar
doctrines effecting the legality and binding nature of obligations or
agreements generally.
