PROSPECTUS SUPPLEMENT SUMMARY This summary highlights information appearing in other sections of this prospectus supplement or the accompanying prospectus. It is not complete and may not contain all of the information that you should consider before investing in the notes we are offering. You should read the entire prospectus supplement and the accompanying prospectus carefully, including the "Risk Factors" section and the financial statements and the footnotes to those statements incorporated by reference in the accompanying prospectus. In this prospectus supplement, references to "Tennessee Gas Pipeline," "we," "us" and "our" mean Tennessee Gas Pipeline Company. References to "El Paso" mean El Paso Corporation. TENNESSEE GAS PIPELINE COMPANY We are a Delaware corporation incorporated in 1947, and a wholly owned subsidiary of El Paso Tennessee Pipeline Co., a direct subsidiary of El Paso Corporation. Our primary business is the interstate transportation and storage of natural gas. We conduct our business activities through two natural gas pipeline systems and a storage facility, each of which is discussed below: The TGP system. The Tennessee Gas Pipeline system consists of approximately 14,200 miles of pipeline with a design capacity of 6,194 million cubic feet per day (MMcf/d). During 2001, 2000 and 1999, average throughput on the TGP system was 4,405 billion British thermal units per day (BBtu/d), 4,354 BBtu/d and 4,253 BBtu/d. This multiple-line system begins in the natural gas producing regions of Louisiana, the Gulf of Mexico and south Texas and extends to the northeast section of the U.S., including the New York City and Boston metropolitan areas. TGP also has an interconnect at the U.S.-Mexico border. Along its system, TGP has approximately 95 billion cubic feet (Bcf) of underground working gas storage capacity, of which 5 Bcf is contracted from ANR Pipeline Company, our affiliate. The Portland System. We have a 30 percent ownership interest in the Portland Natural Gas Transmission system. Portland consists of approximately 300 miles of interstate natural gas pipeline, including lateral lines, with a design capacity of 214 MMcf/d. During 2001, 2000 and 1999, average throughput on the Portland system was 123 BBtu/d, 110 BBtu/d and 61 BBtu/d. Portland's system extends from the Canadian border near Pittsburg, New Hampshire to Dracut, Massachusetts. Bear Creek Storage. We own a 50 percent interest in Bear Creek Storage Company, which owns and operates an underground natural gas storage facility located in Louisiana. Southern Natural Gas Company, our affiliate, owns the remaining 50 percent interest. The facility has a capacity of 50 Bcf of base gas and 58 Bcf of working storage. Bear Creek's working storage capacity is committed equally to the Southern Natural Gas system, which is owned by our affiliate, and our pipeline system under long-term contracts. The following transmission system expansion projects have been approved by the Federal Energy Regulatory Commission (FERC): <Table> <Caption> ANTICIPATED PROJECT CAPACITY DESCRIPTION COMPLETION DATE ------- -------- ----------- --------------- (MMCF/D) Stagecoach 100 Connects the Stagecoach Storage Field in New York Completed to our mainline in Pennsylvania and expands our February 2002 300 Line to provide firm transportation service to interconnect with New Jersey Natural in Passaic, New Jersey.

S-2 SUMMARY FINANCIAL INFORMATION We derived the summary historical consolidated financial data set forth below for each of the three fiscal years ended December 31, 2001 and for the three months ended March 31, 2002 and 2001 from our financial statements. You should read the following information together with the historical financial statements and related notes contained in our 2001 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the period ended March 31, 2002, each of which is incorporated by reference in the accompanying prospectus. <Table> <Caption> THREE MONTHS ENDED YEAR ENDED DECEMBER 31, MARCH 31, ------------------------ ------------- 2001 2000 1999 2002 2001 ------ ------ ------ ----- ----- (UNAUDITED) ($ IN MILLIONS, EXCEPT RATIOS) Operating Results Data: Operating revenues.................................... $728 $748 $785 $188 $214 Depreciation, depletion and amortization.............. 132 134 137 36 33 Operating income...................................... 314 321 330 79 112 Income before income taxes............................ 226 237 256 59 88 Income taxes.......................................... 72 74 82 17 28 Income before cumulative effect of accounting change............................................. 154 163 174 42 60 Cumulative effect of accounting change, net of income taxes(1)........................................... -- -- -- 10 -- Net income............................................ 154 163 174 52 60 Ratio of earnings to fixed charges(2)................. 2.6x 2.7x 2.9x 2.6x 3.6x </Table> <Table> <Caption> AS OF DECEMBER 31, AS OF MARCH 31, ------------------------ --------------- 2001 2000 1999 2002 2001 ------ ------ ------ ------ ------ (UNAUDITED) ($ IN MILLIONS) Financial Position Data: Total assets.................................. $5,527 $5,204 $5,431 $5,644 $5,294 Short-term debt (including current maturities of long-term debt)......................... 424 215 650 527 254 Long-term debt, less current maturities....... 1,356 1,354 1,353 1,356 1,355 Stockholder's equity.......................... 1,901 1,742 1,562 1,953 1,802 </Table> - --------------- (1) We recognized a cumulative effect of accounting change with a gain of $10 million, net of income taxes, related to the write-off of negative goodwill in compliance with Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, and SFAS 142, Goodwill and Other Intangible Assets. (2) The ratio for the year ended 1998 was 1.8x and for 1997 it was 2.0x. For purposes of this computation, earnings represents income from continuing operations before income taxes, interest expense, excluding interest on rate refunds, amortization of debt costs, that portion of rental expense which represents an interest factor, and adjustment to equity earnings to reflect actual distributions from equity investments. Fixed charges means that sum of interest costs, excluding interest on rate refunds, amortization of debt costs, and that portion of rental expense which represents an interest factor. S-3 RISK FACTORS OUR SUCCESS DEPENDS ON FACTORS BEYOND OUR CONTROL. Most of the natural gas we transport and store is owned by third parties. As a result, the volume of natural gas involved in these activities depends on the actions of those third parties, and is beyond our control. Further, the following factors, most of which are beyond our control, may unfavorably impact our ability to maintain or increase current transmission, storage, and sales volumes and rates, to renegotiate existing contracts as they expire or to remarket unsubscribed capacity: - future weather conditions, including those that favor hydroelectric generation or other alternative energy sources; - price competition; - drilling activity and supply availability; - expiration of significant contracts; and - service area competition. THE REVENUES OF OUR PIPELINE BUSINESSES ARE GENERATED UNDER CONTRACTS THAT MUST BE RENEGOTIATED PERIODICALLY. Our revenues are generated under natural gas transportation contracts which expire periodically and must be renegotiated and extended or replaced. Although we actively pursue the renegotiation, extension and/or replacement of these contracts, we cannot assure you that we will be able to extend or replace these contracts when they expire or that the terms of any renegotiated contracts will be as favorable as the existing contracts. In particular, our ability to extend and/or replace transportation contracts could be harmed by factors we cannot control, including: - the proposed construction by other companies of additional pipeline capacity in markets served by us; - changes in state regulation of local distribution companies, which may cause them to negotiate short-term contracts; - reduced demand due to higher natural gas prices; - the availability of alternative energy sources or supply points; and - the viability of our expansion projects. If we are unable to renew, extend or replace these contracts or if we renew them on less favorable terms, we may suffer a material reduction in our revenues and earnings. FLUCTUATIONS IN ENERGY COMMODITY PRICES COULD ADVERSELY AFFECT OUR BUSINESS. If natural gas prices in the supply basins connected to our pipeline systems are higher than prices in other natural gas producing regions, especially Canada, our ability to compete with other transporters may be negatively impacted. Revenues generated by our transmission contracts depend on volumes and rates, both of which can be affected by the prices of natural gas. The success of our transmission operations is subject to continued development of additional oil and natural gas reserves in the vicinity of our facilities and our ability to access additional reserves, primarily in the Gulf of Mexico, to offset the natural decline from existing wells connected to our systems. A decline in energy prices could precipitate a decrease in these development activities and could cause a decrease in the volume of reserves available for S-4 transmission through our systems. Fluctuations in energy prices are caused by a number of factors, including: - regional, domestic and international supply and demand; - availability and adequacy of transportation facilities; - energy legislation; - federal and state taxes, if any, on the sale or transportation of natural gas; and - abundance of supplies of alternative energy sources. If there are reductions in the average volume of the natural gas we transport for a prolonged period, our results of operations and financial position could be significantly, negatively affected. THE RATES WE ARE ABLE TO CHARGE OUR CUSTOMERS MAY BE REDUCED BY GOVERNMENTAL AUTHORITIES. Our pipeline businesses are regulated by the FERC, Department of Transportation and various state and local regulatory agencies. In particular, the FERC generally limits the rates we are permitted to charge our customers for interstate natural gas transportation and, in some cases, sales of natural gas. If the rates we are permitted to charge our customers for use of our regulated pipelines are lowered, or do not recover current cost levels, or if the terms and conditions of tariffs or contracts are modified, our profitability may be reduced. WE WILL FACE COMPETITION FROM THIRD PARTIES TO TRANSPORT, STORE OR OTHERWISE HANDLE NATURAL GAS. The oil and natural gas business is highly competitive. Our competitors include other major pipeline companies, as well as participants in other industries supplying and transporting natural gas to industrial, commercial and individual consumers. If we are unable to compete with services offered by other energy enterprises, which may be larger, offer more services, and possess greater resources, our future profitability may be negatively impacted. COSTS OF ENVIRONMENTAL LIABILITIES, REGULATIONS AND LITIGATION COULD EXCEED OUR ESTIMATES. Our operations are subject to various environmental laws and regulations. These laws and regulations obligate us to clean up various sites at which low-level radioactive substances or other regulated materials may have been disposed of or released. We are also party to legal proceedings involving environmental matters pending in various courts and agencies. It is not possible for us to estimate reliably the amount and timing of all future expenditures related to environmental matters because of: - the difficulty of estimating clean up costs; - the uncertainty in quantifying liability under environmental laws that impose joint and several liability on all potentially responsible parties; - the nature of environmental laws and regulations; and - the possible introduction of future environmental laws and regulations. Although we believe we have established appropriate reserves for liabilities, including clean up costs, we could be required to set aside additional reserves in the future due to these uncertainties. OUR OPERATIONS ARE SUBJECT TO OPERATIONAL HAZARDS AND UNINSURED RISKS. Our operations are subject to the inherent risks normally associated with those operations, including explosions, pollution, release of toxic substances, fires, hurricanes and adverse weather conditions and other hazards, each of which could result in damage to or destruction of our facilities or damages to persons and S-5 property. In addition, our operations face possible risks associated with acts of aggression on our assets. If any of these events were to occur, we could suffer substantial losses. While we maintain insurance against these types of risks to the extent and in amounts that we believe are reasonable, our financial condition and operations could be adversely affected if a significant event occurs that is not fully covered by insurance. S-6 USE OF PROCEEDS The net proceeds from the sale of the notes will be used to repay outstanding commercial paper having a weighted average annual interest rate of 2.62% and for general corporate purposes. Under our cash management agreement with El Paso, we invest our excess cash with El Paso. Some or all of the net proceeds may be invested temporarily with El Paso. CAPITALIZATION The following table sets forth our historical capitalization as of March 31, 2002, and our capitalization as adjusted to reflect the issuance of $240 million of notes and our application of the net proceeds therefrom. This table is unaudited and should be read in conjunction with our 2001 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the period ended March 31, 2002, each of which is incorporated by reference in the accompanying prospectus. <Table> <Caption> AS OF MARCH 31, 2002 ---------------------------- HISTORICAL AS ADJUSTED(1) ---------- -------------- (UNAUDITED) ($ IN MILLIONS) Short-term debt: Commercial paper.......................................... $ 527 $ 289 ------ ------ Total long-term debt........................................ 1,356 1,594 ------ ------ Stockholder's equity: Common stock, par value $5 per share; authorized 300 shares; issued 208 shares.............................. -- -- Additional paid-in capital................................ 1,410 1,410 Retained earnings......................................... 543 543 ------ ------ Total stockholder's equity........................ 1,953 1,953 ------ ------ Total capitalization.............................. $3,836 $3,836 ====== ====== </Table> - ---------- (1) Reflects the issuance of $240 million of notes and the use of net proceeds of $238 million to reduce short-term debt. S-7 DESCRIPTION OF THE NOTES GENERAL The following description of the particular terms of the notes (which represent a new series of, and are referred to in the accompanying prospectus as, the "Debt Securities") supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of the Debt Securities set forth in the accompanying prospectus. The notes will be issued under an indenture, dated as of March 4, 1997, between us and JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as indenture trustee, as supplemented through the date of delivery of the notes. PRINCIPAL, MATURITY AND INTEREST The notes will initially be limited to $240,000,000 aggregate principal amount and will mature on June 15, 2032. We may issue additional notes of this series from time to time in the future which would contain the same terms and the same CUSIP number as the notes offered hereby, without the consent of the holders of the notes, in compliance with the covenants of the indenture. Interest on the notes will: - accrue at 8 3/8% per year from June 10, 2002; - be payable semi-annually on each June 15 and December 15, commencing December 15, 2002; - be payable to the person in whose name the notes are registered at the close of business on the relevant June 1 and December 1 preceding the applicable interest payment date; - be computed on the basis of a 360-day year comprised of twelve 30-day months; and - be payable on overdue interest to the extent permitted by law at the same rate as interest is payable on principal. If any interest payment date, maturity date or redemption date falls on a day that is not a business day, the payment will be made on the next business day (and without any interest or other payment in respect of such delay) with the same force and effect as if made on the relevant interest payment date, maturity date or redemption date. Unless we default on a payment, no interest will accrue from and after the applicable maturity date or redemption date. DEFEASANCE The notes are subject to defeasance and covenant defeasance as described under "Description of Debt Securities -- Satisfaction and Discharge; Legal and Covenant Defeasance" in the accompanying prospectus. As more fully discussed therein, it is likely that a defeasance of the notes by us would result in a taxable event to the holders of the notes under current federal income tax law. OPTIONAL REDEMPTION The notes will be redeemable, in whole or in part, at our option at any time in whole, or from time to time in part, prior to their maturity date, at the Make-Whole Price (as defined below), on not less than 30 calendar days nor more than 60 calendar days notice prior to the date of redemption and in accordance with the provisions of the indenture. "Make-Whole Price" means an amount equal to the greater of: (1) 100% of the principal amount of the notes to be redeemed; and (2) as determined by an Independent Investment Banker, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the redemption date) discounted back to the redemption date on a semi-annual basis S-8 (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points, plus, in the case of both (1) and (2), accrued and unpaid interest to the redemption date. Unless we default in payment of the Make-Whole Price, on and after the applicable redemption date, interest will cease to accrue on the notes to be redeemed. If we redeem a note in part only, a new note of like tenor for the unredeemed portion thereof and otherwise having the same terms as the note partially redeemed will be issued in the name of the holder of the note upon the presentation and surrender thereof. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the notes 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 term of the notes. "Comparable Treasury Price" means, with respect to any redemption date, (1) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Reference Treasury Dealer Quotations. "Independent Investment Banker" means Credit Suisse First Boston Corporation and its successors, or, if such firm or the successors, if any, to such firm, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the trustee after consultation with us. "Reference Treasury Dealer" means Credit Suisse First Boston Corporation and three additional primary U.S. government securities dealers in New York City (each a "Primary Treasury Dealer") selected by the trustee after consultation with us, and their respective successors (provided, however, that if any such firm or any such successor, as the case may be, shall cease to be a primary U.S. government securities dealer in New York City, the trustee, after consultation with us, shall substitute therefor another Primary Treasury Dealer). "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such redemption date. "Treasury Rate" means, with respect to any redemption date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated "H.15(519)" or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Stated Maturity, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the redemption date. Notwithstanding Section 1104 of the indenture, the notice of redemption with respect to the foregoing redemption need not set forth the Make-Whole Price but only the manner of calculation thereof. The Company shall notify the Trustee of the Make-Whole Price with respect to any redemption promptly after the calculation thereof, and the Trustee shall not be responsible for such calculation. S-9 GLOBAL SECURITIES We may issue the notes as permanent global debt securities deposited with a depositary. Unless otherwise indicated in the prospectus supplement, the following is a summary of the depository arrangements applicable to notes issued in permanent global form and for which The Depository Trust Company (DTC) acts as depositary. Each global note will be deposited with, or on behalf of, DTC, as depositary, and registered in the name of Cede & Co., as DTC's nominee, or such other name as may be requested by an authorized representative of DTC. Except under the limited circumstances described below, global notes are not exchangeable for definitive certificated notes. Ownership of beneficial interests in a global note is limited to participants that have accounts with DTC, or persons that may hold interests through those participants. In addition, ownership of beneficial interests by participants in a global note will be evidenced only by, and the transfer of that ownership interest will be effected only through, records maintained by DTC for a global note. Ownership of beneficial interests in a global note by persons that hold through participants will be evidenced only by, and the transfer of that ownership interest within that participant will be effected only through, records maintained by that participant. DTC has no knowledge of the actual beneficial owners of the notes. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the participants through which the beneficial owners entered the transaction. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global note. We will make payment of principal of, and interest on, notes represented by a global note registered in the name of or held by DTC or its nominee, as the case may be, as the registered owner and holder of the global note representing those notes. DTC has advised us that upon receipt of any payment of principal of, or interest on, a global note, DTC will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in the principal amount of that global note as shown in the records of DTC. Payments by participants to owners of beneficial interests in a global note held through those 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 sole responsibility of those participants, subject to any statutory or regulatory requirements that may be in effect from time to time. Neither we, any trustee nor any of our respective agents will be responsible for any aspect of the records of DTC, any nominee or any participant relating to, or payments made on account of, beneficial interests in a permanent global note or for maintaining, supervising or reviewing any of the records of DTC, any nominee or any participant relating to such beneficial interests. A global note is exchangeable for definitive notes registered in the name of, and a transfer of a global note may be registered to, any person other than DTC or its nominee, only if: - DTC notifies us that it is unwilling or unable to continue as depositary for that global note or at any time DTC ceases to be registered under the Exchange Act; - we determine in our discretion that the global note shall be exchangeable for definitive notes in registered form; or - there shall have occurred and be continuing an event of default or an event which, with notice or the lapse of time or both, would constitute an event of default under the notes. Any global note that is exchangeable pursuant to the preceding sentence will be exchangeable in whole for definitive notes in registered form, of like tenor and of an equal aggregate principal amount as the global note, in denominations specified in the applicable prospectus supplement, if other than $1,000 and integral multiples of $1,000. The definitive notes will be registered by the registrar in the name or S-10 names instructed by DTC. We expect that these instructions may be based upon directions received by DTC from its participants with respect to ownership of beneficial interests in the global note. Except as provided above, owners of the beneficial interests in a global note will not be entitled to receive physical delivery of notes in definitive form and will not be considered the holders of notes for any purpose under the indentures. No global note shall be exchangeable except for another global note of like denomination and tenor to be registered in the name of DTC or its nominee. Accordingly, each person owning a beneficial interest in a global note must rely on the procedures of DTC and, if that person is not a participant, on the procedures of the participant through which that person owns its interest to exercise any rights of a holder under the global note or the indentures. We understand that, under DTC's usual procedures, in the event that we request any action of holders, or an owner of a beneficial interest in a global note desires to give or take any action that a holder is entitled to give or take under the notes or the indentures, DTC would authorize the participants holding the relevant beneficial interests to give or take that action, and those participants would authorize beneficial owners owning through those participants to give or take that action or would otherwise act upon the instructions of beneficial owners owning through them. DTC has advised us that DTC is a limited-purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered under the Exchange Act. DTC holds securities that its participants deposit with DTC. DTC also facilitates the settlement of securities transactions among its participants in those securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC's participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is owned by a number of its participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc. Access to DTC's book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC. DTC may discontinue providing its services as securities depositary at any time by giving reasonable notice to us or the Trustee, as agent. Under such circumstances, we would attempt to obtain a successor securities depositary. If we were unable to obtain a successor depository, we would issue notes in definitive form. The information in this section concerning DTC and DTC's book entry system has been obtained from sources that we believe to be reliable, but neither we nor the Trustee take any responsibility for the accuracy of such information. S-11 UNDERWRITING Under the terms and subject to the conditions contained in an underwriting agreement dated June 4, 2002, we have agreed to sell to Credit Suisse First Boston Corporation all of the notes. The underwriting agreement provides that the underwriter is obligated to purchase all of the notes, if any are purchased. The underwriter proposes to offer the notes initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a concession of 0.50 percent of the principal amount per note. The underwriter and selling group members may allow a discount of 0.25 percent of the principal amount per note on sales to other broker/dealers. After the initial public offering, the underwriter may change the public offering price and concession and discount to broker/ dealers. We estimate that our out of pocket expenses for this offering, not including underwriting discounts and commissions, will be approximately $100,000. The notes are new issues of securities with no established trading market. The underwriter intends to make secondary markets for the notes. However, it is not obligated to do so and may discontinue making a secondary market for the notes at any time without notice. No assurance can be given as to how liquid the trading market for the notes will be. We have agreed to indemnify the underwriter against liabilities under the Securities Act of 1933, or to contribute to payments which the underwriter may be required to make in that respect. The underwriter and its affiliates have from time to time performed and may in the future perform various financial advisory, commercial banking and services for us and our affiliates in the ordinary course of business, for which they received or will receive customary fees. In connection with the offering, the underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934. - Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. - Over-allotment involves sales by the underwriter of notes in excess of the principal amount of the notes the underwriter is obligated to purchase, which creates a syndicate short position. - Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. A short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering. - Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the notes originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions. These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time. We expect that delivery of the notes will be made against payment therefor on or about the closing date specified on the cover page of this prospectus supplement, which will be the fourth business day following the date hereof (this settlement cycle being referred to as "T+4"). Under Rule 15c6-1 of the Securities and Exchange Commission under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to that trade expressly agree otherwise. S-12 Accordingly, purchasers who wish to trade notes on the date hereof will be required, by virtue of the fact that the notes initially will settle in T+4, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor. NOTICE TO CANADIAN RESIDENTS RESALE RESTRICTIONS The distribution of the notes in Canada is being made only on a private placement basis exempt from the requirement that we prepare and file a prospectus with the securities regulatory authorities in each province where trades of notes are made. Any resale of the notes in Canada must be made under applicable securities laws which will vary depending on the relevant jurisdiction, and which may require resales to be made under available statutory exemptions or under a discretionary exemption granted by the applicable Canadian securities regulatory authority. Purchasers are advised to seek legal advice prior to any resale of the notes. REPRESENTATIONS OF PURCHASERS By purchasing notes in Canada and accepting a purchase confirmation, a purchaser is representing to us and the dealer from whom the purchase confirmation is received that: - the purchaser is entitled under applicable provincial securities laws to purchase the notes without the benefit of a prospectus qualified under those securities laws; - where required by law, the purchaser is purchasing as principal and not as agent; and - the purchaser has reviewed the text above under Resale Restrictions. RIGHTS OF ACTION -- ONTARIO PURCHASERS ONLY Under Ontario securities legislation, a purchaser who purchases a security offered by this prospectus during the period of distribution will have a statutory right of action for damages, or while still the owner of the notes, for rescission against us in the event that his prospectus contains a misrepresentation. A purchaser will be deemed to have relied on the misrepresentation. The right of action for damages is exercisable not later than the earlier of 180 days from the date the purchaser first had knowledge of the facts giving rise to the cause of action and three years from the date on which payment is made for the notes. The right of action for rescission is exercisable not later than 180 days from the date on which payment is made for the notes. If a purchaser elects to exercise the right of action for rescission, the purchaser will have no right of action for damages against us. In no case will the amount recoverable in any action exceed the price at which the notes were offered to the purchaser and if the purchaser is shown to have purchased the securities with knowledge of the misrepresentation, we will have no liability. In the case of an action for damages, we will not be liable for all or any portion of the damages that are proven to not represent the depreciation in value of the notes as a result of the misrepresentation relied upon. These rights are in addition to, and without derogation from, any other rights or remedies available at law to an Ontario purchaser. The forgoing is a summary of the rights available to an Ontario purchaser. Ontario purchasers should refer to the complete text of the relevant statutory provisions. ENFORCEMENT OF LEGAL RIGHTS All of our directors and officers as well as the experts named here may be located outside of Canada and, as a result, it may not be possible for Canadian purchasers to effect service of process within Canada upon us or those persons. All or a substantial portion of our assets and the assets of those persons may be located outside of Canada and, as a result, it may not be possible to satisfy a judgment against us or those persons in Canada or to enforce a judgment obtained in Canadian courts against us or those persons outside of Canada. S-13 TAXATION AND ELIGIBILITY FOR INVESTMENT Canadian purchasers of notes should consult their own legal and tax advisors with respect to the tax consequences of an investment in the notes in their particular circumstances and about the eligibility of the notes for investment by the purchaser under relevant Canadian legislation. LEGAL MATTERS The validity of the notes offered by this prospectus supplement and the accompanying prospectus will be passed upon for us by Locke Liddell & Sapp LLP, Houston, Texas.

Where any such forward-looking statement includes a statement of the assumptions or bases underlying such forward-looking statement, the Company cautions that, while such assumptions or bases are believed to be reasonable and are made in good faith, assumed facts or bases almost always vary from the actual results, and the differences between assumed facts or bases and actual results can be material, depending upon the circumstances. Where, in any forward-looking statement, the Company, including its subsidiaries, or its management expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and is believed to have a reasonable basis, but there can be no assurance that the statement of expectation or belief will result or be achieved or accomplished. The words "believe," "expect," "estimate," "anticipate" and similar expressions may identify forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements herein include increasing competition within the Company's industry, the timing and extent of changes in commodity prices for natural gas and power, uncertainties associated with acquisitions and joint ventures, potential environmental liabilities, potential contingent liabilities and tax liabilities related to acquisitions, political and economic risks associated with current and future operations in foreign countries, conditions of the equity and other capital markets during the periods covered by the forward-looking statements, and other risks, uncertainties and factors, including the effect of the year 2000 date change, discussed more completely in the Company's other filings with the Securities and Exchange Commission, including the Company's Annual Report on Form 10-K for the year ended December 31, 1997. 2 THE COMPANY GENERAL Tennessee Gas Pipeline Company ("TGP" or the "Company") is a wholly owned subsidiary of El Paso Tennessee Pipeline Co., which in turn is an indirect subsidiary of El Paso Energy Corporation ("El Paso Energy"). Unless the context otherwise requires, references herein to the "Company" shall mean TGP and all of its subsidiaries. The major businesses of the Company consist of the interstate transportation of natural gas, which generally is subject to regulation by the Federal Energy Regulatory Commission, as well as certain other non-regulated business operations, such as natural gas and power marketing, intrastate pipeline operations, international pipelines and power generation, and domestic power generation operations. INTERSTATE SYSTEMS The Company's interstate natural gas transmission operations include three interstate pipeline systems: the TGP System, the Midwestern System, and the East Tennessee System, collectively referred to as the Interstate Systems. The TGP System. The TGP System consists of approximately 14,800 miles of pipeline. The TGP System serves the northeast section of the United States, including the New York City and Boston metropolitan areas. The multiple-line system begins in the gas-producing regions of Texas and Louisiana, including the Gulf of Mexico. The Midwestern System. The Midwestern System consists of approximately 400 miles of pipeline and extends from a connection with the TGP System at Portland, Tennessee to Chicago. The Midwestern System principally serves the Chicago metropolitan area. The East Tennessee System. The East Tennessee System consists of approximately 1,100 miles of pipeline. The East Tennessee System serves the states of Tennessee, Virginia and Georgia and connects with the TGP System in Springfield and Lobelville, Tennessee. Other. The Company owns a 19 percent interest in Portland Natural Gas Transmission ("Portland") System which is developing a 292-mile interstate natural gas pipeline with a projected capacity of 178 million cubic feet per day extending from the Canadian border near Pittsburg, New Hampshire to Dracut, Massachusetts. In April 1998, Portland secured $256 million in non-recourse project financing. Construction started in June 1998 and targeted completion for the project is year-end 1998. FIELD SERVICES The Company's natural gas gathering and processing business provides natural gas gathering, products extraction, dehydration, compression and intrastate transmission services. The Company owns or has interest in approximately 200 miles of gathering systems and approximately 1,300 miles of intrastate transmission pipeline. In addition, the Company owns or has interest in 6 natural gas processing facilities. MERCHANT SERVICES The Company provides a broad range of energy products and services to its customers, including the purchasing, marketing and trading of natural gas, natural gas liquids, power, crude oil and refined products, as well as providing integrated price risk management services associated with these commodities, and the participation in the development and ownership of domestic power generating facilities. With headquarters in Houston, Texas and 8 sales offices throughout the United States and Canada, the Company is one of the industry's leading natural gas and power services providers. 3 INTERNATIONAL The Company has undertaken various activities to extend its traditional activities in North American pipelines to international pipeline, power and energy-related projects, with a current focus on activities in Latin America, Southeast Asia, Australia and Europe. TGP is a Delaware corporation with its principal executive offices located at 1001 Louisiana Street, Houston, Texas 77002. Its telephone number at that address is (713) 420-2131. RECENT DEVELOPMENTS El Paso Energy, the indirect corporate parent of TGP, has recently received a ruling from the Internal Revenue Service that would allow El Paso Energy to reorganize its subsidiaries into a business structure in which TGP would transfer a substantial number of its subsidiaries (and their assets and operations) to El Paso Energy or other entities owned by El Paso Energy. As a result, if El Paso Energy completes such internal reorganization ("the Reorganization"), TGP's primary asset will consist of the TGP System. Completion of the Reorganization will cause TGP to dispose of, and to eliminate from its consolidated financial statements, the following: (i) East Tennessee Natural Gas Company (which owns the East Tennessee System); (ii) Midwestern Gas Transmission Company (which owns the Midwestern System); (iii) all international subsidiaries; (iv) all field services operations; (v) all merchant services operations; and (vi) all subsidiaries with corporate or discontinued operations. If the Reorganization occurs, it is not anticipated that it will occur before late 1998 or early 1999. USE OF PROCEEDS Unless otherwise specified in a supplement to this Prospectus, the net proceeds received by TGP from the sale of the debt securities offered hereby will be used to reduce indebtedness of TGP and for general corporate purposes. Funds not required immediately for such purposes may be invested in marketable securities and short-term investments. RATIO OF EARNINGS TO FIXED CHARGES <Table> <Caption> SIX MONTHS ENDED YEAR ENDED DECEMBER 31, JUNE 30, -------------------------------- 1998(1) 1997 1996 1995 1994 1993 ---------- ---- ---- ---- ---- ---- Ratio of Earnings to Fixed Charges(2)............. 2.80 3.87 3.53 3.20 3.61 3.21 ==== ==== ==== ==== ==== ==== </Table> - --------------- (1) Because of the seasonal nature of TGP's business, the ratio for the six-month period may not necessarily be indicative of the ratio that will result for the full year 1998. (2) In March 1998, El Paso Tennessee Pipeline Co. contributed the common stock of El Paso Marketing Services Company to TGP for a total value of $47 million. The ratio of earnings to fixed charges includes the effects of the contribution of El Paso Marketing Services Company, assuming the transaction had occurred January 1, 1993. For purposes of calculating these ratios: (i) "fixed charges" represent interest cost (exclusive of interest on rate refunds), amortization of debt costs, the estimated portion of rental expense representing the interest factors; and (ii) "earnings" represent the aggregate of income from continuing operations before income taxes, interest expense (exclusive of interest on rate refunds), amortization of debt costs, and the estimated portion of rental expense representing the interest factor, adjusted to reflect actual distributions from equity investments. 4 DESCRIPTION OF DEBT SECURITIES The notes, debentures or other evidences of indebtedness (the "Debt Securities") offered hereby will represent unsecured obligations of TGP. The Debt Securities offered hereby will be issued under one or more supplemental indentures to an Indenture dated as of March 4, 1997 (the "Indenture") between TGP and The Chase Manhattan Bank, as trustee (the "Trustee"). The Indenture does not limit the aggregate principal amount of Debt Securities that may be issued thereunder from time to time in one or more series. The terms of the Debt Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The Debt Securities are subject to all such terms, and holders of Debt Securities are referred to the Indenture and the Trust Indenture Act for a statement of those terms. The statements set forth below in this section are brief summaries of certain provisions contained in the Indenture, do not purport to be complete, and are subject to, and are qualified in their entirety by reference to, all the provisions of the Indenture, including the definitions therein of certain terms, a copy of which Indenture is included as an exhibit to the Registration Statement of which this Prospectus is a part. Capitalized terms used in this section and not otherwise defined in this section have the respective meanings assigned to them in the Indenture.

If any Debt Securities offered hereby are sold for foreign currencies or foreign currency units or if the principal of and premium, if any, or interest, if any, on any series of Debt Securities is payable in foreign currencies or foreign currency units, the restrictions, elections, tax consequences, specific terms and other information with respect to such issue of Debt Securities and such currencies and currency units will be set forth in the Prospectus Supplement relating thereto. Unless otherwise indicated in the Prospectus Supplement relating thereto, the Debt Securities offered hereby will be issued only in fully registered form in denominations of $1,000 or any integral multiple thereof. The Debt Securities of a series may be issuable in the form of one or more global certificates, which will be denominated in an amount equal to all or a portion of the aggregate principal amount of such Debt Securities. See "-- Global Debt Securities." 5 One or more series of Debt Securities offered hereby may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates. The Federal income tax consequences and special considerations applicable to any such series of Debt Securities will be described generally in the Prospectus Supplement relating thereto. GLOBAL DEBT SECURITIES The Debt Securities of a series may be issued in whole or in part in the form of one or more global certificates that will be deposited with, or on behalf of, a depositary (the "Depositary") identified in the Prospectus Supplement relating to such series. Unless and until such global certificate or certificates are exchanged in whole or in part for Debt Securities in individually certificated form, a global Debt Security may not be transferred except as a whole to a nominee of the Depositary for such global Debt Security, or by a nominee for the Depositary to the Depositary, or to a successor of the Depositary or a nominee of such successor. The specific terms of the depositary arrangement with respect to a series of Debt Securities and the rights of, and limitations on, owners of beneficial interests in a global Debt Security representing all or a portion of a series of Debt Securities will be described in the Prospectus Supplement relating to such series.

or (xvi) any extension, renewal, refinancing, refunding or replacement (or successive extensions, renewals, refinancing, refundings or replacements) of any Lien, in whole or in part, that is referred to in clauses (i) through (xv), inclusive, above, or of any Debt secured thereby; provided, however, that the principal amount of Debt secured thereby shall not exceed the greater of the principal amount of Debt so secured at the time of such extension, renewal, refinancing, refunding or replacement and the original principal amount of Debt so secured (plus in each case the aggregate amount of premiums, other payments, costs and expenses required to be paid or incurred in connection with such extension, renewal, refinancing, refunding or replacement);

Notwithstanding the foregoing, under the Indenture, TGP may, and may permit any Restricted Subsidiary to, effect any Sale-Leaseback Transaction that is not excepted by clauses (i) through (iv), inclusive, of the above paragraph, provided that the net sale proceeds from such Sale-Leaseback Transaction, together with the aggregate principal amount of outstanding Debt (other than the Debt Securities) secured by Liens upon Principal Properties not excepted by clauses (i) through (xvi), inclusive, of the first paragraph of the limitation on liens covenant described above, do not exceed 15% of the Consolidated Net Tangible Assets.

CONSOLIDATION, MERGER AND SALE OF ASSETS The Indenture provides that TGP may, without the consent of the Trustee or the holders of any Debt Securities issued thereunder, consolidate or merge with, or sell, lease or transfer its properties and assets as, or substantially as, an entirety to, any Person, provided that (i) either TGP is the surviving entity or such successor Person shall expressly assume the due and punctual payment of the principal of, and any premium and interest on, all the Debt Securities and the performance or observance of every covenant and condition of the Indenture on the part of TGP to be performed or observed, (ii) immediately after giving effect to the transaction, no Default or Event of Default exists, and (iii) TGP has delivered any Officer's Certificate and Opinion of Counsel required by the Indenture. Any such successor Person shall succeed to and be substituted for, and may exercise every right and power of, TGP under the Indenture with the same effect as if it had been named a party in the Indenture and TGP shall, except in the case of a lease, be released and discharged from all its obligations under the Debt Securities and the Indenture. EVENTS OF DEFAULT An "Event of Default" will occur under the Indenture with respect to Debt Securities of any series issued thereunder upon: (a) default in the payment of the principal of, or premium, if any, on, any Debt Security of such series at its maturity; (b) default in the payment of any interest on any Debt Security of such series when it becomes due and payable and continuance of such default for a period of 30 days; (c) default in the performance, or breach, of any term, covenant or warranty contained in the Indenture with respect to such series for a period of 60 days upon giving written notice as provided in the Indenture; (d) the occurrence of certain events of bankruptcy; or (e) any other Event of Default applicable to such series. 9 The Indenture provides that if an Event of Default described in clauses (a), (b), (c) or (e) above shall have occurred and be continuing, either the Trustee or the holders of not less than 25% in principal amount of all affected Debt Securities then outstanding (voting as a single class) may declare the entire principal amount of all affected Debt Securities to be due and payable immediately upon giving written notice as provided in the Indenture. In addition, if an Event of Default described in clause (d) above shall have occurred and be continuing, either the Trustee or holders of not less than 25% in principal amount of all Debt Securities then outstanding may declare the entire principal amount of all Debt Securities outstanding to be due and payable immediately upon giving written notice as provided in the Indenture. The Indenture provides that the holders of a majority in aggregate principal amount of Debt Securities of all affected series then outstanding (voting as a single class) may rescind and annul such declaration and its consequences under certain circumstances. The holders of a majority in aggregate principal amount of all affected Debt Securities then outstanding (voting as a single class) may waive past defaults under the Indenture with respect to all such Debt Securities and their consequences (except a continuing default in the payment of principal of or premium, if any, or interest on any Debt Security or a default in respect of any covenant or provision of the Indenture which cannot be modified or amended by a supplemental indenture without the consent of the holder of each outstanding Debt Security affected thereby). Pursuant to the Indenture, the holders of a majority in aggregate principal amount of all affected Debt Securities then outstanding (voting as a single class) may direct with respect to such series 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, provided that such direction shall not be in conflict with any rule of law or the Indenture. Before proceeding to exercise any right or power under the Indenture at the direction of any holders, the Trustee shall be entitled to receive from such holders reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with any such direction. Under the terms of the Indenture, TGP is required to furnish to the Trustee annually an Officer's Certificate to the effect that to the best of such officer's knowledge, TGP is not in default in the performance and observance of the terms, provisions and conditions of the Indenture or, if such officer has knowledge that TGP is in default, specifying such default. The Indenture requires the Trustee to give to all holders of Debt Securities outstanding thereunder notice of any default by TGP in the manner provided in the Indenture, unless such default shall have been cured or waived; however, except in the case of a default in the payment of principal of and premium, if any, or interest, if any, on any Debt Securities outstanding thereunder, the Trustee is entitled to withhold such notice in the event that the board of directors, the executive committee, or a trust committee of directors or certain officers of the Trustee in good faith determine that withholding such notice is in the interest of the holders of such outstanding Debt Securities. SATISFACTION AND DISCHARGE; LEGAL AND COVENANT DEFEASANCE Under the terms of the Indenture, TGP may satisfy and discharge certain obligations to holders of Debt Securities of any series which have not already been delivered to the Trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year or are to be called for redemption within one year by (i) depositing or causing to be deposited with the Trustee funds in an amount sufficient to pay the principal and any premium and interest to the date of such deposit (in case of Debt Securities of such series which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be, (ii) paying or causing to be paid all other sums payable under the Indenture with respect to such Debt Securities, and (iii) delivering to the Trustee an Officer's Certificate and Opinion of Counsel relating to such satisfaction and discharge. The Indenture also provides that TGP and any other obligor, if any, will be discharged from any and all obligations in respect of any series of Debt Securities issued thereunder (excluding, however, certain obligations, such as the obligation to register the transfer or exchange of such outstanding Debt Securities of such series, to replace stolen, lost, mutilated or destroyed certificates, to pay principal and interest on the original stated due dates or specified redemption date, to make any sinking fund payments, and to maintain 10 paying agencies) on the 91st day following the deposit referred to in the following clause (i), subject to the following conditions: (i) the irrevocable deposit, in trust, of cash or U.S. Government Obligations (or a combination thereof) which through the payment of interest and principal thereof in accordance with their terms will provide cash in an amount sufficient to pay the principal and interest and premium, if any, on the outstanding Debt Securities of such series and any mandatory sinking fund payments, in each case, on the stated maturity of such payments in accordance with the terms of the Indenture and the outstanding Debt Securities of such series or on any Redemption Date established pursuant to clause (iii) below; (ii) TGP's receipt of an Opinion of Counsel based on the fact that (A) TGP has received from, or there has been published by, the Internal Revenue Service a ruling, or (B) since the date of the Indenture, there has been a change in the applicable federal income tax law, in either case, to the effect that, and confirming that, the holders of the Debt Securities will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times, as would have been the case if such deposit and defeasance had not occurred; (iii) if the Debt Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to the Indenture or provision therefor satisfactory to the Trustee shall have been made; (iv) no Event of Default or event which with notice or lapse of time or both would become an Event of Default will have occurred and be continuing on the date of such deposit; and (v) TGP's delivery to the Trustee of an Officer's Certificate and an Opinion of Counsel, each stating that the conditions precedent under the Indenture have been complied with. Under the Indenture, TGP also may discharge its obligations referred to above under "-- Certain Covenants" and "-- Consolidation, Merger and Sale of Assets," as well as certain of its obligations relating to reporting obligations under the Indenture, in respect of any series of Debt Securities on the 91st day following the deposit referred to in clause (i) in the immediately preceding paragraph, subject to satisfaction of the conditions described in clauses (i), (iii), (iv) and (v) in the immediately preceding paragraph with respect to such series of Debt Securities and the delivery of an Opinion of Counsel confirming that the holders of the Debt Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to Federal income tax on the same amount and in the same manner and at the same times, as would have been the case if such deposit and covenant defeasance had not occurred. CHANGES IN CONTROL AND HIGHLY LEVERAGED TRANSACTIONS The Indenture does not contain provisions requiring redemption of the Debt Securities issued thereunder, or adjustment to any terms of such Debt Securities, upon any change in control of TGP. Other than the limitations on Liens and the restriction on Sale-Leaseback Transactions described above under "-- Certain Covenants," the Indenture does not contain any covenant or other provisions designed to afford holders of the Debt Securities issued thereunder protection in the event of a highly leveraged transaction involving TGP. MODIFICATION OF THE INDENTURE The Indenture provides that TGP and the Trustee may enter into supplemental indentures without the consent of the holders of Debt Securities issued thereunder to: (a) secure any of such Debt Securities; (b) evidence the succession of another Person to TGP under the Indenture and the Debt Securities and the assumption by such successor Person of the obligations of TGP thereunder; (c) add covenants and Events of Default for the benefit of the holders of all or any series of such Debt Securities or to surrender any right or power conferred by the Indenture upon TGP; (d) add to, change or eliminate any of the provisions of the Indenture, provided that any such addition, change or elimination shall become effective only after there are no such Debt Securities of any series entitled to the benefit of such provision outstanding; (e) establish the forms or terms of the Debt Securities of any series issued thereunder; (f) cure any ambiguity or correct any inconsistency in the Indenture; (g) evidence the acceptance of appointment by a successor trustee; and (h) qualify the Indenture under the Trust Indenture Act. 11 The Indenture also contains provisions permitting TGP and the Trustee, with the consent of the holders of a majority in aggregate principal amount of all outstanding Debt Securities affected by such supplemental indenture (voting as a single class), to add any provisions to, or change in any manner or eliminate any of the provisions of, the Indenture, or modify in any manner the rights of the holders of such Debt Securities, provided that TGP and the Trustee may not, without the consent of the holder of each outstanding Debt Security affected thereby, (a) change the stated maturity of the principal of or any installment of principal of or interest, if any, on, any Debt Security, or reduce the principal amount thereof or premium, if any, on or the rate of interest thereon, (b) reduce the percentage in principal amount of Debt Securities required for any such supplemental indenture or for any waiver provided for in the Indenture, (c) change TGP's obligation to maintain an office or agency for payment of Debt Securities and the other matters specified therein, or (d) modify any of the provisions of the Indenture relating to the execution of supplemental indentures with the consent of holders of Debt Securities which are discussed in this paragraph or modify any provisions relating to the waiver by holders of past defaults and certain covenants, except to increase any required percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the holder of each outstanding Debt Security affected thereby. NO PERSONAL LIABILITY OF OFFICERS, DIRECTORS, EMPLOYEES OR STOCKHOLDERS No director, officer, employee or stockholder, as such, of TGP or any of its affiliates shall have any personal liability in respect of the obligations of TGP under the Indenture or the Debt Securities by reason of his, her or its status as such. APPLICABLE LAW The Indenture is, and the Debt Securities offered hereby will be, governed by, and construed in accordance with, the laws of the State of New York. CONCERNING THE TRUSTEE The Indenture provides that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. If an Event of Default has occurred and is continuing, the Trustee will use the same degree of care and skill in its exercise of the rights and powers vested in it by the Indenture as a prudent person would exercise under the circumstances in the conduct of such person's own affairs. The Indenture contains limitations on the rights of the Trustee, should it become a creditor of TGP, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of such claims, as security or otherwise. The Trustee is permitted to engage in other transactions; provided, however, that if it acquires any conflicting interest, it must eliminate such conflict or resign. The Chase Manhattan Bank, a New York banking corporation, is the Trustee under the Indenture. TGP and its affiliates maintain banking and other commercial relationships with The Chase Manhattan Bank in the ordinary course of business. In particular, The Chase Manhattan Bank is the agent and a lender under the revolving credit facilities of El Paso Energy and TGP credit facilities. 12 PLAN OF DISTRIBUTION TGP may offer or sell Debt Securities to or through one or more underwriters, dealers or agents as designated from time to time, or through a combination of such methods, and also may offer or sell the Debt Securities directly to one or more other purchasers.
