AMENDMENTS
TO THE INDENTURE




The
amendments and supplements contained herein shall apply to 2018 Notes only and
not to any other series of Debt Securities issued under the Original Indenture
and any covenants provided herein are expressly being included solely for the
benefit of the 2018 Notes.  These amendments and supplements shall be
effective for so long as there remain any 2018 Notes outstanding.




SECTION
2.1  Definitions.




Section
1.01 of the Original Indenture is amended and supplemented by inserting or
restating, as the case may be, in their appropriate alphabetical position, the
following definitions:




“Attributable
Indebtedness” means with respect to a Sale-Leaseback Transaction, at the time of
determination, the lesser of:




(a) 
the fair market value (as determined in good faith by the Board of Directors) of
the assets involved in the Sale-Leaseback Transaction;




(b) 
the present value of the total net amount of rent required to be paid under the
lease involved in such Sale-Leaseback Transaction during the remaining term
thereof (including any renewal term exercisable at the lessee’s option or period
for which such lease has been extended), discounted at the rate of interest set
forth or implicit in the terms of such lease or, if not practicable to determine
such rate, the weighted average interest rate per annum borne by the 2018 Notes
compounded semiannually; and




(c) 
if the obligation with respect to the Sale-Leaseback Transaction constitutes an
obligation that is required to be classified and accounted for as a Capital
Lease Obligation for financial reporting purposes in accordance with GAAP, the
amount equal to the capitalized amount of such obligation determined in
accordance with GAAP and included in the financial statements of the
lessee.






For
purposes of the foregoing definition, rent will not include amounts required to
be paid by the lessee, whether or not designated as rent or additional rent, on
account of or contingent upon maintenance and repairs, insurance, taxes,
assessments, utilities, water rates, operating charges, labor costs and similar
charges.  In the case of any lease that is terminable by the lessee
upon the payment of a penalty, such net amount shall be the lesser of the net
amount determined assuming termination upon the first date such lease may be
terminated (in which case the net amount shall also include the amount of the
penalty, but no rent shall be considered as required to be paid under such lease
subsequent to the first date upon which it may be so terminated) or the net
amount determined assuming no such termination.




- 4 -




“Capital Lease Obligation” means, at the time any determination thereof is to be
made, the amount of the liability in respect of a capital lease that would at
such time be required to be capitalized on a balance sheet in accordance with
GAAP.




“Consolidated
Net Tangible Assets” means, at any date of determination, the aggregate amount
of total assets included in the most recent consolidated quarterly or annual
balance sheet of the Partnership prepared in accordance with GAAP, less
applicable reserves reflected in such balance sheet, after deducting the
following amounts:




(a) 
all current liabilities reflected in such balance sheet (excluding any current
maturities of long-term debt or any current liabilities that by their terms are
extendable or renewable at the option of the obligor to a time more than 12
months after the time as of which the amount is being computed);
and




(b) 
all goodwill, trade names, trademarks, patents, unamortized debt discount and
expense and other like intangibles reflected in such balance sheet.




“Funded
Debt” means all Debt maturing one year or more from the date of the incurrence,
creation, assumption or guarantee thereof, all Debt directly or indirectly
renewable or extendable, at the option of the debtor, by its terms or by the
terms of the instrument or agreement relating thereto, to a date one year or
more from the date of the incurrence, creation, assumption or guarantee thereof,
and all Debt under a revolving credit or similar agreement obligating the lender
or lenders to extend credit over a period of one year or more.

Liens existing at, or provided for under the terms of an “after-acquired

than a Permitted Lien, on any Principal Property or upon any shares of capital
stock of any Subsidiary owning or leasing any Principal Property, whether now
existing or hereafter created or acquired by the Partnership or such Subsidiary,
to secure any Debt of the Partnership or any other Person, without in any such
case making effective provision whereby any and all 2018 Notes then Outstanding
will be secured by a Lien equally and ratably with, or prior to, such Debt for
so long as such Debt shall be so secured.  Notwithstanding the
foregoing, the Partnership may, and may permit any Subsidiary to, incur, create,
assume or suffer to exist any Lien (other than a Permitted Lien) on any
Principal Property or upon any shares of capital stock of any Subsidiary owning
or leasing any Principal Property to secure Debt of the Partnership or any other
Person, without securing the 2018 Notes as provided in this Section, provided
that the aggregate principal amount of all Debt then outstanding secured by any
such Lien together with the aggregate amount of Attributable Indebtedness deemed
to be outstanding in respect of all Sale-Leaseback Transactions (exclusive of
any such Sale-Leaseback Transactions otherwise permitted under clauses (a) and
(c) of Section 4.12), does not exceed 10% of Consolidated Net Tangible
Assets.




Section
4.14. Additional
Subsidiary Guarantors.  If at any time after the original
issuance of the 2018 Notes, including following any release of a Subsidiary
Guarantor from its Guarantee under this Indenture, any Subsidiary of the
Partnership (including any future Subsidiary of the Partnership) guarantees any
Funded Debt of the Partnership, then the Partnership shall cause such Subsidiary
to guarantee the 2018 Notes and in connection with such guarantee, to execute
and deliver an Indenture supplemental hereto pursuant to Section 9.01(g)
simultaneously therewith.  In order to further evidence its Guarantee,
such Subsidiary shall execute and deliver to the Trustee a notation relating to
such Guarantee in accordance with Section 14.02.”




SECTION
2.4  Events of
Default.




The
following additional Event of Default shall be added to those in clauses (a)-(g)
of Section 6.01 of the Original Indenture in relation to the 2018
Notes:




“(h)
default in the payment by the Partnership or any of its Subsidiaries at the
Stated Maturity thereof, after the expiration of any applicable grace period, of
any principal of any Debt of the Partnership (other than the 2018 Notes) or any
of its Subsidiaries (other than the Guarantee of the 2018 Notes) outstanding in
an aggregate principal amount in excess of $50,000,000, or the occurrence of any
other default thereunder (including, without limitation, the failure to pay
interest or any premium), the effect of which default is to cause such Debt to
become, or to be declared, due prior to its Stated Maturity and such
acceleration is not rescinded within 60 days after there has been given, by
registered or certified mail, to the Partnership and the Subsidiary Guarantors
by the Trustee or to the Partnership, the Subsidiary Guarantors and the Trustee
by the Holders of at least 25% in principal amount of the Outstanding 2018 Notes
a written notice specifying such default and requiring it to be remedied and
stating that such notice is a “Notice of Default” hereunder, and the receipt by
the Partnership and the Subsidiary Guarantors of such written
notice.”

[FORM
OF REVERSE OF 2018 NOTE]




This
Security is one of a duly authorized issue of the series of Debt Securities of
the Company designated as its 6.65% Senior Notes due 2018 (such series being
herein called the “Securities”), which is issued under, with securities of one
or more additional series that may be issued under, an indenture dated as of
February 20, 2002, among the Company, the Subsidiary Guarantors and U.S.
Bank National Association, successor to Wachovia Bank, National Association and
First Union National Bank, as trustee (herein called the “Trustee,” which term
includes any successor trustee under the Indenture), as amended and supplemented
by the Sixth Supplemental Indenture dated as of March 27, 2008 (such Indenture,
as so amended and supplemented, being called the “Indenture”), to which
Indenture and all future indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties,
obligations and immunities thereunder of the Company, the Subsidiary Guarantors,
the Trustee and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered.




The
Securities are redeemable, at the option of the Company, at any time in whole,
or from time to time in part, at a redemption price (the “Make-Whole Price”)
equal to the greater of: (i) 100% of the principal amount of the Securities to
be redeemed; and (ii) the sum of the present values of the remaining
scheduled payments of principal and interest (at the rate in effect on the date
of calculation of the Make-Whole Price) on the Securities to be redeemed
(exclusive of interest accrued to the date of redemption (the “Redemption
Date”)) discounted to the Redemption Date on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the applicable Treasury
Yield plus 50 basis points; plus, in either case, accrued interest to the
Redemption Date.




The actual Make-Whole
Price, calculated as provided above, shall be calculated and certified to the
Trustee and the Company by the Independent Investment Banker. For purposes of
determining the Make-Whole Price, the following definitions are
applicable:




“Treasury
Yield” means, with respect to any Redemption Date applicable to the Securities,
the rate per annum equal to the semi-annual equivalent yield to maturity
(computed as of the third Business Day immediately preceding such Redemption
Date) of the Comparable Treasury Issue, assuming a price for the Comparable
Treasury Issue (expressed as a percentage of its principal amount) equal to the
applicable Comparable Treasury Price for the Redemption Date.





“Comparable
Treasury Issue” means the United States Treasury security selected by the
Independent Investment Banker as having a maturity comparable to the remaining
term of the Securities to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining
terms of the Securities to be redeemed; provided, however,that if no
maturity is within three months before or after the maturity date for the
Securities, yields for the two published maturities most closely corresponding
to such United States Treasury security will be determined and the treasury rate
will be interpolated or extrapolated from those yields on a straight line basis
rounding to the nearest month.





“Independent
Investment Banker” means any of UBS Securities LLC, J.P. Morgan Securities Inc.,
SunTrust Robinson Humphrey, Inc. and Wachovia Capital Markets, LLC (and their
respective successors) or, if no such firm is willing and able to select the
applicable Comparable Treasury Issue or perform the other functions of the
Independent Investment Banker provided in the Indenture, an independent
investment banking institution of national standing appointed by the Trustee and
reasonably acceptable to the Company.





“Comparable
Treasury Price” means, with respect to any Redemption Date, (a) the average
of four Reference Treasury Dealer Quotations for the Redemption Date, after
excluding the highest and lowest Reference Treasury Dealer Quotations, or
(b) if the Independent Investment Banker obtains fewer than four Reference
Treasury Dealer Quotations, the average of all such quotations.





“Reference
Treasury Dealer” means (a) each of UBS Securities LLC, J.P. Morgan Securities
Inc. and Wachovia Capital Markets, LLC (or its relevant affiliate) and their
respective successors; and (b) one other primary U.S. government securities
dealer in the United States selected by the Company (each, a “Primary Treasury
Dealer”); provided, however, that if any of the foregoing shall resign as a
Reference Treasury Dealer, the Company will substitute therefor another Primary
Treasury Dealer.


A-3


“Reference
Treasury Dealer Quotations” means, with respect to each Reference Treasury
Dealer and any Redemption Date for the Securities, an average, as determined by
an Independent Investment Banker, of the bid and asked prices for the Comparable
Treasury Issue for the Securities (expressed in each case as a percentage of its
principal amount) quoted in writing to an Independent Investment Banker by such
Reference Treasury Dealer at 5:00 p.m., New York City time, on the third
Business Day preceding such Redemption Date.




Securities
called for optional redemption become due on the Redemption Date. Notices of
optional redemption will be mailed at least 30 but not more than 60 days
before the Redemption Date to each Holder of the Securities to be redeemed at
its registered address. The notice of optional redemption for the Securities
will state, among other things, the amount of Securities to be redeemed, the
Redemption Date, the method of calculating such Make-Whole Price and the
place(s) that payment will be made upon presentation and surrender of Securities
to be redeemed. Unless the Company defaults in payment of the Make-Whole Price,
interest will cease to accrue on the Redemption Date with respect to any
Securities that have been called for optional redemption. If less than all the
Securities are redeemed at any time, the Trustee will select the Securities to
be redeemed on a pro rata basis or by any other method the Trustee deems fair
and appropriate.




The Securities may be
redeemed in part in multiplies of $1,000 only. Any such redemption will also
comply with Article III of the Indenture.




Except as
set forth above, the Securities will not be redeemable prior to their Stated
Maturity and will not be entitled to the benefit of any sinking
fund.




As set forth in the Indenture, an Event of Default with respect to the
Securities is generally: (a) failure to pay principal upon Stated Maturity,
redemption or otherwise; (b) default for 30 days in payment of interest on
any of the Securities; (c) failure for 60 days after notice to comply with
any other covenants in the Indenture or the Securities; (d) certain payment
defaults under, or the acceleration prior to the Stated Maturity of, Debt of the
Company or any Subsidiary in an aggregate principal amount in excess of
$50,000,000, unless such acceleration is rescinded within 60 days after notice
to the Company and the Subsidiary Guarantors as provided in the Indenture;
(e) the Guarantee of the Securities by any of the Subsidiary Guarantors
ceases to be in full force and effect (except as otherwise provided in the
Indenture); and (f) certain events of bankruptcy, insolvency or
reorganization of the Company or any Subsidiary Guarantor.




If an Event of Default described in clause (f) in the preceding paragraph
occurs, then the principal amount of all Outstanding Securities, premium, if
any, and interest thereon shall ipso facto be due and payable
immediately.  If any other Event of Default with respect to the
Securities occurs and is continuing, the Trustee or the holders of at least 25%
in aggregate principal amount of the Outstanding Securities may declare the
principal amount of all the Securities, premium, if any, and accrued interest
thereon to be due and payable immediately.  The Indenture provides
that such declaration may be rescinded in certain events by the Holders of a
majority in principal amount of the Outstanding Securities.




No Holder of the Securities may pursue any remedy under the Indenture unless the
Trustee shall have failed to act within 60 days after notice of an Event of
Default with respect to the Securities and written request by Holders of at
least 25% in principal amount of the Outstanding Securities, and the offer to
the Trustee of indemnity reasonably satisfactory to it; however, such provision
does not affect the right to sue for enforcement of any overdue payment on a
Security by the Holder thereof.  Subject to certain limitations,
Holders of a majority in principal amount of the Outstanding Securities may
direct the Trustee in its exercise of any trust or power.  The Trustee
may withhold from Holders notice of any continuing default (except default in
payment of principal, premium or interest) if it determines in good faith that
withholding the notice is in the interest of the Holders.  The Company
is required to file a report with the Trustee each year as to the absence or
existence of defaults.




The Company’s payment obligations under the Securities are jointly and severally
guaranteed by the Subsidiary Guarantors.  Any Subsidiary Guarantor may
be released from its Guarantee of the Securities under the circumstances
described in the Indenture.




The Indenture contains
provisions for defeasance at any time of (i) the entire indebtedness of the
Company and Subsidiary Guarantors on this Security and (ii) certain Events
of Default, upon compliance by the Company with certain conditions set forth
therein, which provisions apply to this Security.




A-4


The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company or the Subsidiary Guarantors and the rights of the Holders of the Securities
under the Indenture at any time by the Company, the Subsidiary Guarantors and
the Trustee with the consent of the Holders of at least a majority in aggregate
principal amount of the Securities at the time Outstanding.  The
Indenture also contains provisions permitting the Holders of at least a majority
in principal amount of the Securities at the time Outstanding, on behalf of the
Holders of all the Securities, to waive compliance by the Company or the
Subsidiary Guarantors with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences.  Any such consent
or waiver by or on behalf of the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security and of any
Security issued upon the registration of transfer hereof or in exchange herefor
or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.  Without the consent of any Holder, the Company,
the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture
or the Securities to cure any ambiguity, defect or inconsistency, to make other
changes that do not adversely affect the rights of any Holder and to make
certain other specified changes.




No
reference herein to the Indenture and no provision of this Security or of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of (and premium, if any, on) and
interest on this Security at the times, place, and rate, and in the coin or
currency, herein prescribed.




As
provided in the Indenture and subject to certain limitations therein set forth,
the transfer of this Security is registerable in the Debt Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company maintained for such purpose, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Registrar duly executed by, the Holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Securities, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.




The
Securities are issuable only in registered form without coupons in denominations
of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Securities
are exchangeable for a like aggregate principal amount of Securities of a
different authorized denomination, as requested by the Holder surrendering the
same.




No
service charge shall be made for any registration of transfer or exchange of
Securities, but the Company may require payment of a sum sufficient to cover any
tax, fee, assessment or other governmental charge payable in connection
therewith.




The
General Partner and its directors, officers, employees, incorporators and
stockholders, as such, shall have no liability for any obligations of the
Subsidiary Guarantors or the Company under the Securities, the Indenture or the
Guarantee or for any claim based on, in respect of, or by reason of, such
obligations or their creation.  Each Holder, by accepting this
Security, waives and releases all such liability.  Such waiver and
release are part of the consideration for the issuance of this
Security.




Prior to
the time of due presentment of this Security for registration of transfer, the
Company, Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security is overdue, and neither the Company, the
Trustee nor any agent shall be affected by notice to the contrary.




All terms
used in this Security which are defined in the Indenture shall have the meanings
assigned to them in the Indenture.  The Company will furnish to any
Holder upon written request and without charge a copy of the
Indenture.  Requests may be made to TEPPCO Partners, L.P., 1100
Louisiana Street, Suite 1800, Houston, Texas 77002, Attn: Investor
Relations.




Pursuant
to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Company has caused CUSIP numbers to be printed on
the Securities as a convenience to the Holders thereof.  No
representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identifying information
printed hereon.




This
Security shall be governed by and construed in accordance with the laws of the
State of New York.
