                      PANHANDLE EASTERN PIPE LINE COMPANY

     On March 29, 1999, CMS Energy Corporation ("CMS ENERGY") acquired all of
the outstanding common stock of Panhandle, its principal consolidated
subsidiaries, Trunkline Gas Company ("TRUNKLINE") and Pan Gas Storage Company
("PAN GAS STORAGE"), as well as Panhandle's affiliates, Panhandle Storage
Company ("PANHANDLE STORAGE") and Trunkline LNG Company ("TRUNKLINE LNG"), from
subsidiaries of Duke Energy Corporation. As a result of a corporate
reorganization at that time, Panhandle Storage and Trunkline LNG became direct,
wholly-owned subsidiaries of Panhandle. See "-- Acquisition by CMS Energy
Corporation."

     We are primarily engaged in the transportation of natural gas in interstate
commerce. We operate one of the nation's largest natural gas pipeline networks,
providing customers in the Southwest and Midwest with a comprehensive array of
transportation and storage services. This interconnected 10,400 mile system
accesses virtually all major natural gas supply regions in the United States.

     Our Panhandle transmission system consists of a system of four
large-diameter parallel pipelines, extending approximately 1,300 miles from
producing areas in the Anadarko Basin of Texas, Oklahoma and Kansas through
Missouri, Illinois, Indiana and Ohio into Michigan.

     Our Trunkline transmission system consists of a system of three
large-diameter parallel pipelines, extending approximately 1,400 miles from the
Gulf Coast areas of Texas and Louisiana through Arkansas, Mississippi,
Tennessee, Kentucky, Illinois and Indiana to a point on the Indiana-Michigan
border. We also own and operate two offshore Louisiana natural gas supply
systems consisting of 337 miles of pipeline extending approximately 81 miles
into the Gulf of Mexico.

     We own and operate five underground gas storage fields located in Illinois,
Michigan, Kansas, Oklahoma and Louisiana with a combined maximum working storage
capacity of 70 billion cubic feet.

     We own a liquified natural gas ("LNG") regasification plant and related LNG
tanker port, unloading facilities and LNG and gas storage facilities located at
Lake Charles, Louisiana. The LNG plant has the capacity to deliver 700 million
cubic feet per day but has been operated on a limited basis for a number of
years.

     Our Panhandle transmission system's major customers include approximately
20 utilities located in the Midwest market area that encompasses large portions
of Michigan, Ohio, Indiana, Illinois and Missouri. Our Trunkline transmission
system's major customers include eight utilities located in portions of
Illinois, Indiana, Michigan, Ohio and Tennessee.

ACQUISITION BY CMS ENERGY CORPORATION

     On March 29, 1999, CMS Energy acquired all of our outstanding common stock
from Duke Energy Corporation ("DUKE ENERGY"). CMS Energy paid $1.9 billion in
cash to Duke Energy and assumed $300 million of our existing debt.

     CMS Energy is a leading diversified energy company operating in the United
States and around the world. CMS Energy's two principal subsidiaries are

("ENTERPRISES"). Consumers is a public utility that provides natural gas and
electricity to almost six million of the nine and one-half million residents in
Michigan's Lower Peninsula. Enterprises, through subsidiaries, is engaged in
several domestic and international energy businesses including:

     - Natural gas transmission, storage and processing;

     - Independent power production;

     - Oil and gas exploration and production;

     - International energy distribution; and

     - Energy marketing, services and trading.

     Our acquisition by CMS Energy excluded certain of our non-strategic assets.
See "Unaudited Pro Forma Financial Information" for a description of
restructuring, realignment and elimination of certain activities between us and
Duke Energy prior to the closing of the acquisition.

     Pursuant to the stock purchase agreement between subsidiaries of Duke
Energy and CMS Energy, Duke Energy has agreed to investigate and remedy
environmental damage to some of our properties. Duke Energy has agreed to
continue its clean-up effort at these properties post acquisition and to defend
and indemnify us against certain future environmental litigation and claims.

                                  RISK FACTORS

     In addition to the information set forth in this Prospectus, you should
carefully consider the risks described below before making an investment in the
Exchange Notes. The risks described below are not the only ones facing us.
Additional risks not presently known to us or that we currently deem immaterial
may also impair our business operations.

DOMESTIC COMPETITION AND REGULATORY RESTRUCTURING

     Federal and state regulation of natural gas interstate pipelines has
changed dramatically in the last two decades and could continue to change over
the next several years. In general, such regulatory changes have resulted and
will continue to result in increased competition in our business. In order to
meet competitive challenges, we will need to adapt our marketing strategies, the
type of transportation and storage services we offer to our customers and our
pricing and rate responses to competitive forces in order to maintain and grow
our business. We will also need to respond to changes in state regulation in our
market area that allow direct sales to all retail end-user customers or, at
least, broader customer classes than now allowed. We are not able to predict the
financial consequences of these changes at this time, but they could have a
material adverse effect on our financial results.

     Federal Energy Regulatory Commission ("FERC") policy allows the issuance of
certificates authorizing the construction of new interstate pipelines which are
competitive with existing pipelines. A number of new pipeline and pipeline
expansion projects have been approved or are pending approval by the FERC in
order to transport large additional volumes of natural gas to the Midwest from
Canada. These pipelines will be able to compete with us. Increased competition
could reduce the volumes of gas transported by us to our existing markets or
cause us to lower rates in order to meet competition. This could have a material
adverse effect on our financial results.

NO PUBLIC MARKET FOR THE EXCHANGE NOTES

     There is no active trading market for the Exchange Notes and this market
may never develop. If any of the Exchange Notes are traded after their initial
issuance, they may trade at a discount from their initial offering price.
Factors that could cause the Exchange Notes to trade at a discount are:

     - an increase in prevailing interest rates;

     - a decline in our credit worthiness;

     - a weakness in the market for similar securities; and

     - declining general economic conditions.

     Although we have entered into a registration rights agreement with the
Donaldson, Lufkin & Jenrette Securities Corporation, Barclays Capital Inc, Chase
Securities Inc. NationsBanc Montgomery Securities LLC, First Chicago Capital
Markets, Inc., Salomon Smith Barney Inc., and SG Cowen Securities Corporation
(collectively the "INITIAL PURCHASERS") under which we are obligated to file a
registration statement and to use our best efforts to have it declared
effective, which would allow you to exchange the Notes for

                                       10
<PAGE>   14

Exchange Notes which are registered under the Securities Act of 1933, we cannot
assure you that the registration statement although filed will be declared
effective, that the exchange will occur, or that an active market for the
Exchange Notes will develop. The liquidity of, and trading markets for, the
Exchange Notes may also be adversely affected by declines in the markets for
high-yield securities generally.

RISK OF YEAR 2000 NONCOMPLIANCE

     Many existing computer programs were designed and developed without
considering the upcoming change in the century, which could lead to the failure
of computer applications or create erroneous results by or at the year 2000.
This issue is referred to as the "YEAR 2000 ISSUE." The Year 2000 Issue is a
broad business issue, whose impact extends beyond traditional computer hardware
and software to possible failure of automated plant systems and instrumentation
as well as to business third parties. Also, there can be no guarantee that third
parties of business importance to us will successfully reprogram or replace, and
test, all of their own computer hardware, software and process control systems
to ensure such systems are Year 2000 compliant. Failure by us, third parties of
business importance to us and/or other constituents such as governments to
become Year 2000 compliant on a timely basis could have a material adverse
effect on our financial position and results of operations.

RESULTS COULD DIFFER MATERIALLY FROM CERTAIN FORWARD-LOOKING STATEMENTS

     From time to time, we may make statements regarding our assumptions,
projections, expectations, intentions or beliefs about future events. These
statements are intended as "forward-looking statements" under the Private
Securities Litigation Reform Act of 1995. We caution that these statements may
and often do vary from actual results and the differences between these
statements and actual results can be material. Accordingly, we cannot assure you
that actual results will not differ materially from those expressed or implied
by the forward-looking statements. Some of the factors that could cause actual
achievements and events to differ materially from those expressed or implied in
any forward-looking statements are:

     - entry of competing pipelines into our markets and competitive strategies
       of competing pipelines, including rate and other pricing practices;

     - state and federal legislative and regulatory initiatives that affect cost
       and investment recovery, have an impact on rate structures, and affect
       the speed and degree to which competition enters the natural gas
       industry;

     - the weather and other natural phenomena;

     - the timing and extent of changes in prices of commodities (primarily
       natural gas and competing fuels) and interest rates;

     - changes in environmental and other laws and regulations to which we and
       our subsidiaries are subject or other external factors over which we have
       no control;

     - the results of financing efforts;

     - expansion and other growth opportunities; and

                                       11
<PAGE>   15

     - the effect of accounting policies issued periodically by accounting
       standard-setting bodies.

These factors are discussed more completely in our filings with the SEC,
including our annual report on Form 10-K for the year ended December 31, 1998,
and our quarterly report on Form 10-Q for the quarter ended March 31, 1999 which
are incorporated by reference into this Prospectus.

                                USE OF PROCEEDS

     There will be no net proceeds payable to us from the issuance of the
Exchange Notes. The net proceeds from the sale of the Notes, together with funds
from CMS Energy, were used to fund CMS Energy's acquisition of the Panhandle
Companies.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The consolidated ratio of earnings to fixed charges for each of the years
ended December 31, 1994 through 1998 and the three months ended March 31, 1999
is as follows:

                                  THE COMPANY

     We are an indirectly wholly owned subsidiary of CMS Energy. We and our
subsidiaries are primarily engaged in the interstate transportation and storage
of natural gas. Our interstate natural gas transmission and storage operations
are subject to the rules and regulations of the FERC. We were incorporated in
Delaware in 1929.

     On March 29, 1999, CMS Energy acquired all of our outstanding common stock
and the outstanding common stock of our principal consolidated subsidiaries,
Trunkline and Pan Gas Storage, as well as our affiliates, Panhandle Storage and
Trunkline from subsidiaries of Duke Energy Corporation. Panhandle Storage and
Trunkline LNG became our direct, wholly-owned subsidiaries. CMS Energy paid $1.9
billion in cash to Duke Energy Corporation and assumed $300 million of existing
Panhandle debt.

NATURAL GAS TRANSMISSION

     We own approximately 10,400 miles of interstate pipeline systems.
Panhandle's natural gas transmission system, which consists of four
large-diameter parallel pipelines and 13 mainline compressor stations, extends a
distance of approximately 1,300 miles from producing areas in the Anadarko Basin
of Texas, Oklahoma and Kansas through the state of Missouri, Illinois, Indiana
and Ohio into Michigan. Trunkline's transmission system extends approximately
1,400 miles from the Gulf Coast areas of Texas and Louisiana through the states
of Arkansas, Mississippi, Tennessee, Kentucky, Illinois and Indiana to a point
on the Indiana-Michigan border. The system consists principally of three large-
diameter parallel pipelines, 18 mainline compressor stations and one offshore
compressor platform.

     Trunkline also owns and operates two offshore Louisiana gas supply systems
consisting of 337 miles of pipeline extending approximately 81 miles into the
Gulf of Mexico.

     Our throughput volumes for the years 1994 to 1998 were 1,186 TBtu, 1,182
TBtu, 1,319 TBtu, 1,279 TBtu and 1,141 TBtu, respectively. A substantial
majority of delivered volumes of our interstate pipelines represents gas
transported under long-term service agreements with local distribution company
(LDC) customers in the pipelines' market areas. Firm transportation services are
also provided under contract to gas marketers, producers, other pipelines,
electric power generators and a variety of end-users. In addition, the pipelines
offer both firm and interruptible transportation to customers on a short-term or
seasonal basis. Demand for gas transmission on our pipeline systems is seasonal,
with the highest throughput occurring during the colder periods in the first and
fourth quarters.

Panhandle's major customers include 20 utilities located in the Midwest market
area that encompasses large portions of Michigan, Ohio, Indiana, Illinois and
Missouri. Trunkline's major customers include eight utilities located in
portions of Tennessee, Missouri, Illinois, Indiana and Michigan.

NATURAL GAS STORAGE AND LNG FACILITY

     Our Pan Gas Storage subsidiary also owns and operates three underground
storage fields located in Illinois, Michigan and Oklahoma with working gas
capacity of 31 Bcf. Pan Gas Storage is also the owner and operator of a 26 Bcf
storage field in Kansas. Trunkline owns and operates one 13 Bcf storage field in
Louisiana. Since the implementation of Order 636, Panhandle, Trunkline and Pan
Gas Storage each provide firm and interruptible storage on an open-access basis.
See "Regulation" below. In addition to owning and operating storage fields,
Panhandle also leases storage capacity. Panhandle and Trunkline have retained
the right to use up to 15 Bcf and 10 Bcf, respectively, of their storage
capacity for system needs.

     Our subsidiary, Trunkline LNG, owns a LNG regasification plant and related
LNG tanker port, unloading facilities and LNG and gas storage facilities located
at Lake Charles, Louisiana. The LNG plant has the capacity to deliver 700
million cubic feet per day but has been operated on a limited basis for a number
of years.

REGULATION

     The FERC has authority to regulate rates and charges for natural gas
transported in or stored for interstate commerce or sold by a natural gas
company in interstate commerce for resale. The FERC also has authority over the
construction and operation of pipeline and related facilities utilized in the
transportation and sale of natural gas in interstate commerce, including the
extension, enlargement or abandonment of such facilities. Panhandle Trunkline
and Pan Gas Storage hold certificates of public convenience and necessity issued
by the FERC, authorizing them to construct and operate the pipelines, facilities
and properties now in operation for which such certificates are required, and to
transport and store natural gas in interstate commerce.

     Our pipelines operate as open-access transporters of natural gas. In 1992,
the FERC issued Order 636, which requires open-access pipelines to provide firm
and interruptible transportation services on an equal basis for all gas
supplies, whether purchased from the pipeline or from another gas supplier. To
implement this requirement, Order 636 provided, among other things, for
mandatory unbundling of services that historically had been provided by
pipelines into separate open-access transportation, sales and storage services.
Order 636 allows pipelines to recover eligible costs, known as "transition
costs," resulting from the implementation of Order 636.

     Regulation of the importation and exportation of natural gas is vested in
the Secretary of Energy, who has delegated various aspects of this jurisdiction
to Office of Fossil Fuels of the Department of Energy.

     We are also subject to the Natural Gas Pipeline Safety Act of 1968, which
regulates gas pipeline safety requirements, and to the Hazardous Liquid Pipeline
Safety Act of 1979, which regulates oil and petroleum pipelines.

                       DESCRIPTION OF THE EXCHANGE NOTES

     The 2004 Exchange Notes, 2009 Exchange Notes and 2029 Exchange Notes will
be issued as one series of debt securities under an Indenture dated March 29,
1999 (the "BASE INDENTURE") and supplemented by a First Supplemental Indenture,
also dated March 29, 1999 establishing the Exchange Notes (the "SUPPLEMENTAL
INDENTURE") among us, CMS Panhandle Holdings Company ("CMS HOLDING") and Bank
One Trust Company, NA, successor to NBD Bank, as Trustee (the "TRUSTEE"). The
Base Indenture and the Supplemental Indenture are hereinafter referred to
collectively as the "INDENTURE." On June 15, 1999 CMS Holding merged with and
into Panhandle and all obligations of CMS Holding under the Indenture were
assumed by us. The following summaries of certain provisions of the Indenture,
the Exchange Notes and the Registration Rights Agreement (as defined herein) do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, all provisions of the respective documents, including
the definitions therein of certain terms. Certain capitalized terms used in this
"Description of the Exchange Notes" shall have the meanings respectively set
forth in the Indenture or the Registration Rights Agreement, as applicable.
Wherever particular defined terms of the Indenture are referred to, such defined
terms are incorporated herein by reference as part of the statement made, and
the statement is qualified in its entirety by such reference. Copies of the
Indenture are available from the Trustee upon request.

     The 2004 Exchange Notes will be limited in aggregate principal amount of
$300 million, the 2009 Exchange Notes will be limited in aggregate principal
amount of $200 million and the 2029 Exchange Notes will be limited in aggregate
principal amount of $300 million. The Indenture does not limit the aggregate
principal amount of debt securities that may be issued thereunder and provides
that debt securities may be issued thereunder, from time to time, in one or more
series. The Exchange Notes and all other debt securities hereafter issued under
the Indenture are collectively referred to herein as the "SECURITIES."

GENERAL

     The Exchange Notes will be unsecured debt securities of Panhandle and will
rank pari passu with all senior unsecured debt of Panhandle and senior to all
subordinated debt of Panhandle. Panhandle does not currently have any
subordinated debt.

     The Exchange Notes will be issued in the form of one or more Global
Exchange Notes, in registered form, without coupons, in denominations of $1,000
or an integral multiple thereof as described under "-- Book-Entry; Delivery;
Form and Transfer." The Global Exchange Notes will be registered in the name of
a nominee of DTC. Each Global Exchange Note (and any Exchange Note issued in
exchange therefor) will be subject to certain restrictions on transfer set forth
therein as described under "-- Book-Entry; Delivery; Form and
Transfer -- Transfers of Interests in Global Exchange Notes for Certificated
Exchange Notes." Except as set forth herein under "-- Book-Entry; Delivery; Form
and Transfer -- Transfers of Interests in Global Exchange Notes for Certificated
Exchange Notes," owners of beneficial interests in a Global Exchange Note will
not be entitled to have Exchange Notes registered in their names, will not
receive or be entitled to receive physical delivery of any such Exchange Note
and will not be considered the registered holder thereof under the Indenture.

     Because the 2004 Exchange Notes, the 2009 Exchange Notes and the 2029
Exchange Notes are treated as one series and one class of securities for the
purposes of the

                                       15
<PAGE>   19

Indenture, certain actions to be taken by the holders of the Exchange Notes
pursuant to the terms of the Indenture may be taken by the holders of the
specified percentage of the aggregate principal amount of all the Exchange Notes
then outstanding, combined. As a result of voting together as holders of one
series of Securities with respect to matters covered by the Indenture, the
holders of one or two of the three tranches of the Exchange Notes (i.e., the
2004 Exchange Notes, the 2009 Exchange Notes and the 2029 Exchange Notes) will
likely be able to determine the outcome of holder actions without obtaining the
consent of holders of the other tranche(s) of Exchange Notes. Future issuances
of Securities under the Indenture may be aggregated with the Exchange Notes for
voting purposes and could further affect the ability of the holders of the
Exchange Notes to effect the outcome of holder actions.

PAYMENT AND MATURITY

     The 2004 Exchange Notes will mature on March 15, 2004, the 2009 Exchange
Notes will mature on July 15, 2009 and the 2029 Exchange Notes will mature on
July 15, 2029, in each case unless redeemed earlier by Panhandle as described
below, and will bear interest at the rate of 6.125%, 6.500% and 7.000%,
respectively, per annum. At the relevant maturity date, Panhandle will pay the
aggregate principal amount of the then outstanding Exchange Notes which have
come due.

     Each Exchange Note will bear interest from the original date of issue of
the Notes. Interest on the 2004 Exchange Notes will be payable semiannually in
arrears on March 15 and September 15, commencing September 15, 1999, and at
maturity. Interest on the 2009 Exchange Notes and the 2029 Exchange Notes will
be payable semiannually in arrears on January 15, and July 15, commencing
January 15, 2000, and at maturity. So long as Exchange Notes are held in the
form of one or more Global Exchange Notes, payments of principal, premium,
interest and Liquidated Damages (as defined herein), if any, will be payable
through the facilities of DTC.

     Payment of any interest due on the Exchange Notes will be made to the
Persons in whose name the Exchange Notes are registered at the close of business
on the Record Date for such interest payments. The record dates for the 2004
Exchange Notes shall be the March 1 or September 1 preceding the applicable
payment date, and the record dates for the 2009 Exchange Notes and the 2029
Exchange Notes shall be the January 1 or July 1 preceding the applicable payment
date. In any case where any interest payment date, repurchase date or maturity
of any Exchange Note will not be a Business Day (as hereinafter defined) at any
place of payment, then payment of interest or principal (and premium, if any)
need not be made on that date, but may be made on the next succeeding Business
Day at such place of payment with the same force and effect as if made on the
interest payment date, repurchase date or at maturity; and no interest will
accrue on the amount so payable for the period from and after such interest
payment date, redemption date, repurchase date or maturity, as the case may be,
to such Business Day.

REDEMPTION

     Each of the Exchange Notes will be redeemable at the option of Panhandle at
any time and from time to time, in whole or in part, upon not less than 30 nor
more than 45 days notice to each holder of such Exchange Notes, at a redemption
price equal to the Make-Whole Price of such Exchange Notes. "MAKE-WHOLE PRICE"
means an amount equal to the greater of (1) 100% of the principal amount of the
Exchange Notes to be

                                       16
<PAGE>   20

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 discounted to the date of redemption on a semi-annual basis (assuming a
360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate,
plus, in each case, accrued and unpaid interest thereon to the date of
redemption. Unless there is a default in the payment of the redemption price, on
and after the date of redemption, interest will cease to accrue on Exchange
Notes or portions thereof called for redemption.

     "ADJUSTED TREASURY RATE" means, with respect to any date of redemption, the
     rate per annum equal to the semi-annual equivalent yield to maturity of the
     Comparable Treasury Issue, assuming a price for the Comparable Treasury
     Issue (expressed as a percentage of its principal amount) equal to the
     Comparable Treasury Price at such date of redemption, plus 15 basis points
     (0.15%) in the case of the 2004 Exchange Notes, 25 basis points (0.25%) in
     the case of the 2009 Exchange Notes and 40 basis points (0.40%) in the case
     of the 2029 Exchange Notes.

     "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 2004 Exchange Notes, 2009 Exchange
     Notes or 2029 Exchange Notes, as the case may be, 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 such Exchange
     Notes.

     "COMPARABLE TREASURY PRICE" means, with respect to any date of redemption,
     (1) the average of the bid and asked prices for the Comparable Treasury

                                       23

                                       24
<PAGE>   28

     (4) Panhandle or such Restricted Subsidiary, within an 18-month period
     after such Sale-Leaseback Transaction, applies or causes to be applied an
     amount not less than the net sale proceeds from such Sale-Leaseback
     Transaction to (A) the repayment, redemption or retirement of Funded Debt
     of Panhandle or any Subsidiary, or (B) investment in another Principal
     Property or in a Subsidiary of Panhandle which owns another Principal

     (4) the occurrence of certain events of bankruptcy.

     If an Event of Default with respect to the Exchange Notes occurs and is
continuing, either the Trustee or the holders of at least 33% in aggregate
principal amount of the outstanding Exchange Notes by notice as provided in the
Indenture may declare the principal amount of all the Exchange Notes to be due
and payable immediately. At any time after a declaration of acceleration with
respect to the Exchange Notes has been made, but before a judgment or decree for
payment of money has been obtained by the Trustee, the holders of a majority in
aggregate principal amount of the outstanding Exchange Notes, under certain
circumstances, may rescind and annul such acceleration.

          The Indenture provides that, subject to the duty of the Trustee during
     default to act with the required standard of care, the Trustee will be
     under no obligation to exercise any of its rights or powers under the

     holders shall have offered to the Trustee reasonable indemnity. Subject to
     such provisions for the indemnification of the Trustee, the holders of a
     majority in aggregate principal amount of the outstanding Exchange Notes

     proceeding for any remedy available to the Trustee, or exercising any trust
     or power conferred on the Trustee, with respect to the Exchange Notes;
     provided, however, that

                                       25
<PAGE>   29

     the Trustee shall not be obligated to take any action unduly prejudicial to
     holders not joining in such direction or involving the Trustee in personal
     liability.

     The holders of a majority in aggregate principal amount of the outstanding
Exchange Notes may, on behalf of all holders of Exchange Notes, waive any past
default under the Indenture with respect to any Exchange Notes, except a
default:

     (1) in the payment of principal of, or premium, if any, or any interest on
     any Exchange Note; or

     (2) in respect of a covenant or provision of the Indenture which cannot be
     modified or amended without the consent of the holder of each outstanding
     Exchange Note affected.

     Panhandle is required to furnish to the Trustee annually a statement as to
     the performance by it of its obligations under the Indenture and as to any
     default in such performance.

LEGAL AND COVENANT DEFEASANCE

destroyed certificates, and to maintain paying agencies) on the 123rd day
following the deposit referred to in the following clause (1), subject to the
following conditions: (1) 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 Exchange Notes 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 Exchange Notes or on any redemption date
established pursuant to clause (3) below; (2) receipt by Panhandle of an Opinion
of Counsel based on the fact that (A) Panhandle 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
Exchange Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such deposit and defeasance and will be subject to
federal income tax on the same amount and in the same manner and at the same
times, as would have been the case if such deposit and defeasance had not
occurred; (3) if any Exchange Notes 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; (4) 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 (5) Panhandle's delivery to the Trustee of an Officers'
Certificate and an Opinion of Counsel, each stating that the conditions
precedent under the Indenture have been complied with.

     Under the Indenture, Panhandle also may discharge its obligations referred
to above under "-- Limitation on Restricted Payments," "-- Limitation on Liens,"
"-- Restriction on Sale-Leasebacks," "-- Limitation on Other Business
Activities" and "-- Consolidation,

Merger and Sale of Assets," as well as certain of their obligations relating to
reporting obligations under the Indenture, in respect of the Exchange Notes on
the 123rd day following the deposit referred to in clause (1) in the immediately
preceding paragraph, subject to satisfaction of the conditions described in
clauses (1), (3), (4) and (5) in the immediately preceding paragraph with
respect to the Exchange Notes and the delivery of an Opinion of Counsel
confirming that the holders of the Exchange Notes 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.

MODIFICATION AND WAIVER

     Modifications and amendments of the Indenture may be made by Panhandle and
the Trustee with the consent of the holders of a majority in aggregate principal
amount of the outstanding Exchange Notes, provided, however, that no such
modification or amendment may, without consent of the holder of each outstanding
Exchange Note affected thereby:

     (1) change the Stated Maturity of the principal of, or the time of payment
     of any installment of principal of or interest on, any Exchange Note;

     (2) reduce the principal amount of, or premium or interest on, any Exchange
     Note;

     (3) change the coin or currency in which any Exchange Note or any premium
     or interest thereon is payable;

     (4) reduce the percentage in principal amount of outstanding Exchange
     Notes, the consent of whose holders is required for modification or
     amendment of the Indenture or for waiver of compliance with certain
     provisions of the Indenture or for waiver of certain defaults; or

     (5) modify any of the above provisions.

     The holders of a majority in aggregate principal amount of the outstanding
Exchange Notes may, on behalf of the holders of all Exchange Notes, waive,
insofar as the Exchange Notes are concerned, compliance by Panhandle with
certain restrictive provisions of the Indenture.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     Panhandle, without the consent of the holders of any of the outstanding
Exchange Notes, may consolidate with or merge into, or convey, transfer or lease
its assets substantially as an entirety to, any Person which is a corporation,
partnership or trust organized and validly existing under the laws of any
domestic jurisdiction, provided that any successor Person assumes Panhandle's
obligations on the Exchange Notes and under the Indenture, that after giving
effect to the transaction no Event of Default, and no event which, after notice
or lapse of time, would become an Event of Default, shall have occurred and be
continuing, and that certain other conditions are met.

GOVERNING LAW

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

                                       27

REGARDING THE TRUSTEE

     Panhandle and certain of its affiliates from time to time borrow money
from, and maintain deposit accounts and conduct certain banking transactions
with, the Trustee or its affiliates in the ordinary course of their business.

BOOK-ENTRY; DELIVERY; FORM AND TRANSFER

     The Exchange Notes which are exchanged for Notes which were sold to
qualified institutional buyers ("QIB'S") will be issued initially in the form of
one or more registered global Exchange Notes without interest coupons
(collectively the "GLOBAL EXCHANGE NOTES"). Upon issuance, the Global Exchange
Notes will be deposited with the Trustee, as custodian for DTC, and registered
in the name of DTC or its nominee, in each case for credit to the accounts of
DTC's Direct and Indirect Participants (as defined below).

     The Global Exchange Notes may be transferred, in whole and not in part,
only to another nominee of DTC or to a successor of DTC or its nominee in
certain limited circumstances. Beneficial interests in the Global Exchange Notes
may be exchanged for Exchange Notes in certificated form in certain limited
circumstances. See "-- Transfer of Interests in Global Exchange Notes for
Certificated Exchange Notes."

  DEPOSITARY PROCEDURES

     DTC has advised Panhandle that DTC is a limited-purpose trust company
created to hold securities for its participating organizations (collectively,
the "Direct Participants") and to facilitate the clearance and settlement of
transactions in those securities between Direct Participants through electronic
book-entry changes in accounts of Participants. The Direct Participants include
securities brokers and dealers (including the Initial Purchasers), banks, trust
companies, clearing corporations and certain other organizations. Access to
DTC's system is also available to other entities that clear through or maintain
a direct or indirect, custodial relationship with a Direct Participant
(collectively, the "Indirect Participants"). DTC may hold securities
beneficially owned by other persons only through the Direct Participants or
Indirect Participants, and such other persons' ownership interest and transfer
of ownership interest will be recorded only on the records of the appropriate
Direct Participant and/or Indirect Participant, and not on the records
maintained by DTC.

     DTC has also advised Panhandle that, pursuant to DTC's procedures, (1) upon
deposit of the Global Exchange Notes, DTC will credit the accounts of the Direct
Participants designated by the Initial Purchasers with portions of the principal
amount of the Global Exchange Notes allocated by the Initial Purchasers to such
Direct Participants, and (2) DTC will maintain records of the ownership
interests of such Direct Participants in the Global Exchange Notes and the
transfer of ownership interests by and between Direct Participants. DTC will not
maintain records of the ownership interests of, or the transfer of ownership
interests by and between, Indirect Participants or other owners of beneficial
interests in the Global Exchange Notes. Direct Participants and Indirect
Participants must maintain their own records of the ownership interests of, and
the transfer of ownership interests by and between, Indirect Participants and
other owners of beneficial interests in the Global Exchange Notes.

                                       28
<PAGE>   32

     The laws of some states require that certain persons take physical delivery
in definitive, certificated form, of securities that they own. This may limit or
curtail the ability to transfer beneficial interests in a Global Exchange Note
to such persons. Because DTC can act only on behalf of Direct Participants,
which in turn act on behalf of Indirect Participants and others, the ability of
a person having a beneficial interest in a Global Exchange Note to pledge such
interest to persons or entities that are not Direct Participants in DTC, or to
otherwise take actions in respect of such interests, may be affected by the lack
of physical certificates evidencing such interests. For certain other
restrictions on the transferability of the Exchange Notes see "-- Transfers of
Interests in Global Exchange Notes for Certificated Exchange Notes."

     EXCEPT AS DESCRIBED IN "-- TRANSFERS OF INTERESTS IN GLOBAL EXCHANGE NOTES
FOR CERTIFICATED EXCHANGE NOTES," OWNERS OF BENEFICIAL INTERESTS IN THE GLOBAL
EXCHANGE NOTES WILL NOT HAVE EXCHANGE NOTES REGISTERED IN THEIR NAMES, WILL NOT
RECEIVE PHYSICAL DELIVERY OF EXCHANGE NOTES IN CERTIFICATED FORM AND WILL NOT BE
CONSIDERED THE REGISTERED OWNERS OR HOLDERS THEREOF UNDER THE INDENTURE FOR ANY
PURPOSE.

     Under the terms of the Indenture, Panhandle and the Trustee will treat the
persons in whose names the Exchange Notes are registered (including Exchange
Notes represented by Global Exchange Notes) as the owners thereof for the
purpose of receiving payments and for any and all other purposes whatsoever.
Payments in respect of the principal, premium, Liquidated Damages, if any, and
interest on Global Exchange Notes registered in the name of DTC or its nominee
will be payable by the Trustee to DTC or its nominee as the registered holder
under the Indenture. Consequently, neither Panhandle, the Trustee nor any agent
of Panhandle or the Trustee has or will have any responsibility or liability for
(1) any aspect of DTC's records or any Direct Participant's or Indirect
Participant's records relating to or payments made on account of beneficial
ownership interests in the Global Exchange Notes or for maintaining, supervising
or reviewing any of DTC's records or any Direct Participant's or Indirect
Participant's records relating to the beneficial ownership interests in any
Global Exchange Note or (2) any other matter relating to the actions and
practices of DTC or any of its Direct Participants or Indirect Participants.

     DTC has advised Panhandle that its current payment practice (for payments
of principal, interest and the like) with respect to securities such as the
Exchange Notes is to credit the accounts of the relevant Direct Participants
with such payment on the payment date in amounts proportionate to such Direct
Participant's respective ownership interests in the Global Exchange Notes as
shown on DTC's records. Payments by Direct Participants and Indirect
Participants to the beneficial owners of the Exchange Notes will be governed by
standing instructions and customary practices between them and will not be the
responsibility of DTC, the Trustee or Panhandle. Neither Panhandle nor the
Trustee will be liable for any delay by DTC or its Direct Participants or
Indirect Participants in identifying the beneficial owners of the Exchange
Notes, and Panhandle and the Trustee may conclusively rely on and will be
protected in relying on instructions from DTC or its nominee as the registered
owner of the Exchange Notes for all purposes.

     The Global Exchange Notes will trade in DTC's Same-day Funds Settlement
System and, therefore, transfers between Direct Participants in DTC will be
effected in accordance with DTC's procedures, and will be settled in immediately
available funds. Transfers between Indirect Participants who hold an interest
through a Direct Participant will be effected in accordance with the procedures
of such Direct Participant but generally will settle in immediately available
funds.

                                       29
<PAGE>   33

     DTC has advised Panhandle that it will take any action permitted to be
taken by a holder of Exchange Notes only at the direction of one or more Direct
Participants to whose account interests in the Global Exchange Notes are
credited and only in respect of such portion of the aggregate principal amount
of the Exchange Notes as to which such Direct Participant or Direct Participants
has or have given direction. However, if there is an Event of Default with
respect to the Exchange Notes, DTC reserves the right to exchange Global
Exchange Notes (without the direction of one or more of its Direct Participants)
for legended Exchange Notes in certificated form, and to distribute such
certificated forms of Exchange Notes to its Direct Participants. See
"-- Transfers of Interests in Global Exchange Notes for Certificated Exchange
Notes."

     Although DTC has agreed to the foregoing procedures to facilitate transfers
of interests in Global Exchange Notes among Direct Participants, they are under
no obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. None of the Initial Purchasers or
the Trustee will have any responsibility for the performance by DTC or its
respective Direct and Indirect Participants of their respective obligations
under the rules and procedures governing any of their operations.

     The information in this section concerning DTC and its book-entry system
has been obtained from sources that Panhandle believes to be reliable, but
Panhandle does not take any responsibility for the accuracy thereof.

  TRANSFERS OF INTERESTS IN GLOBAL EXCHANGE NOTES FOR CERTIFICATED EXCHANGE
  NOTES

     An entire Global Exchange Note may be exchanged for Certificated Exchange
Notes if (1) (a) DTC notifies Panhandle that it is unwilling or unable to
continue as Depositary for the Global Exchange Notes or Panhandle determines
that DTC is unable to act as such Depositary and Panhandle thereupon fails to
appoint a successor depositary within 90 days or (b) DTC has ceased to be a
clearing agency registered under the Exchange Act, (2) Panhandle at its option,
notifies the Trustee in writing that it elects to cause the issuance of
Certificated Exchange Notes or (3) there shall have occurred and be continuing a
Default or an Event of Default with respect to the Exchange Notes. In any such
case, Panhandle will notify the Trustee in writing that, upon surrender by the
Direct and Indirect Participants of their interest in such Global Exchange Note,
Certificated Exchange Notes will be issued to each person that such Direct and
Indirect Participants and the DTC identify as being the beneficial owner of the
related Exchange Notes.

     Beneficial interests in Global Exchange Notes held by any Direct or
Indirect Participant may be exchanged for Certificated Exchange Notes upon
request to DTC, by such Direct Participant (for itself or on behalf of an
Indirect Participant), to the Trustee in accordance with customary DTC
procedures. Certificated Exchange Notes delivered in exchange for any beneficial
interest in any Global Exchange Note will be registered in the names, and issued
in any approved denominations, requested by DTC on behalf of such Direct or
Indirect Participants (in accordance with DTC's customary procedures).

     Neither Panhandle nor the Trustee will be liable for any delay by the
holder of the Global Exchange Notes or DTC in identifying the beneficial owners
of Exchange Notes, and Panhandle and the Trustee may conclusively rely on, and
will be protected in relying on, instructions from the holder of the Global
Exchange Note or DTC for all purposes.

                                       30
<PAGE>   34

  CERTIFICATED EXCHANGE NOTES

     Certificated Exchange Notes may be exchangeable for other Certificated
Exchange Notes of any authorized denominations and of a like aggregate principal
amount and tenor. Certificated Exchange Notes may be presented for exchange, and
may be presented for registration of transfer (duly endorsed, or accompanied by
a duly executed written instrument of transfer), at the designated office of the
Trustee in Detroit, Michigan (the "SECURITY REGISTRAR"). The Security Registrar
will not charge a service charge for any registration of transfer or exchange of
Exchange Notes; however, Panhandle may require payment by a holder of a sum
sufficient to cover any tax, assessment or other governmental charge payable in
connection therewith, as described in the Indenture. Such transfer or exchange
will be effected upon the Security Registrar or such other transfer agent, as
the case may be, being satisfied with the documents of title and identity of the
person making the request. Panhandle may at any time designate additional
transfer agents with respect to the Exchange Notes.

     Panhandle shall not be required to (a) issue, exchange or register the
transfer of any Certificated Exchange Note for a period of 15 days next
preceding the mailing of notice of redemption of such Exchange Note or (b)
exchange or register the transfer of any Certificated Exchange Note or portion
thereof selected, called or being called for redemption, except in the case of
any Certificated Exchange Note to be redeemed in part, the portion thereof not
so to be redeemed.

     If a Certificated Exchange Note is mutilated, destroyed, lost or stolen, it
may be replaced at the office of the Security Registrar upon payment by the
holder of such expenses as may be incurred by Panhandle and the Security
Registrar in connection therewith and the furnishing of such evidence and
indemnity as Panhandle and the Security Registrar may require. Mutilated
Exchange Notes must be surrendered before new Exchange Notes will be issued.

  SAME DAY SETTLEMENT

     Payments in respect of the Exchange Notes represented by the Global
Exchange Notes (including principal, premium, if any, interest and Liquidated
Damages, if any) will be made by wire transfer of immediately available same day
funds to the accounts specified by the holder of interests in such Global
Exchange Note. Principal, premium, if any, and interest and Liquidated Damages,
if any, on all Certificated Exchange Notes in registered form will be payable at
the office or agency of the Trustee in The City of New York, except that, at the
option of Panhandle, payment of any interest and Liquidated Damages, if any, may
be made (1) by check mailed to the address of the Person entitled thereto as
such address shall appear in the security register or (2) by wire transfer to an
account maintained by the Person entitled thereto as specified in the security
register.

                               THE EXCHANGE OFFER

REGISTRATION RIGHTS; LIQUIDATED DAMAGES

     The Notes were sold by CMS Holding on March 29, 1999, pursuant to the
Purchase Agreement dated March 23, 1999 (the "PURCHASE AGREEMENT") by and among
CMS Holding, Panhandle and the Initial Purchasers and were subsequently offered
by the Initial Purchasers to qualified institutional buyers pursuant to Rule
144A that are accredited investors in a manner exempt from registration under
the Securities Act as well as to purchasers pursuant to Regulation S under the
Securities Act.

     The summary herein of certain provisions of the Registration Rights
Agreement does not purport to be complete and reference is made to the
provisions of the Registration Rights Agreement which has been filed as an
exhibit to the Exchange Offer Registration Statement and a copy of which is
available as set forth in "Where to Find More Information."

     CMS Holding, Panhandle and the Initial Purchasers entered into the
Registration Rights Agreement pursuant to which CMS Holding and Panhandle agreed
to file with the SEC a registration statement (the "EXCHANGE OFFER REGISTRATION
STATEMENT") on the appropriate form under the Securities Act with respect to the
offer to exchange the 2004 Notes, 2009 Notes and 2029 Notes for a new series of
notes (the "EXCHANGE NOTES"), registered under the Securities Act with terms
substantially identical to those of the 2004 Notes, 2009 Notes and 2029 Notes
(the "EXCHANGE OFFER") (except that the Exchange Notes will not contain terms
with respect to transfer restrictions). On June 15, 1999 CMS Holding merged with
and into Panhandle and all obligations of CMS Holding under the Registration
Rights Agreement were assumed by Panhandle. Upon the effectiveness of the
Exchange Offer Registration Statement, Panhandle will offer Exchange Notes
pursuant to the Exchange Offer in exchange for Transfer Restricted Securities
(as defined herein) to the holders of Transfer Restricted Securities who are
able to make certain representations. If (1) Panhandle is not required to file
the Exchange Offer Registration Statement or permitted to consummate the
Exchange Offer because the Exchange Offer is not permitted by applicable law or
SEC policy or (2) any holder of Transfer Restricted Securities notifies
Panhandle that (A) it is prohibited by law or SEC policy from participating in
the Exchange Offer or (B) it may not resell the Exchange Notes acquired by it in
the Exchange Offer to the public without delivering a prospectus and the
prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales or (C) it is a broker-dealer and owns
Notes acquired directly from CMS Holding or Panhandle or an affiliate of CMS
Holding or Panhandle, Panhandle will file with the SEC a shelf registration
statement (the "SHELF REGISTRATION STATEMENT") to cover resales of the Notes by
the holders thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. Panhandle will
use its best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the SEC. For purposes of the
foregoing, "TRANSFER RESTRICTED SECURITIES" means each Note until (1) the date
on which such Note has been exchanged by a person other than a broker-dealer for
an Exchange Note in the Exchange Offer, (2) following the exchange by a
broker-dealer in the Exchange Offer of a Note for an Exchange Note, the date on
which such an Exchange Note is sold to a purchaser who receives from such
broker-dealer on or prior to the date of such sale a copy of the this
Prospectus, (3) the date on which such Note has been effectively registered
under the Securities Act and disposed of in accordance with the

                                       32
<PAGE>   36

Shelf Registration Statement, or (4) the date on which such Note is eligible to
be distributed to the public pursuant to Rule 144 under the Securities Act.

     On June 15, 1999, CMS Holding merged with and into Panhandle and all
obligations of CMS Holding under the Registration Rights Agreement were assumed
by Panhandle. Therefore, the following description of the Registration Rights
Agreement which describes joint obligations of CMS Holding and Panhandle refers
only to Panhandle's obligations since pursuant to its merger with CMS Holding it
has assumed all of CMS Holding's obligations under the Registration Rights
Agreement. The Registration Rights Agreement provides that (1) Panhandle will
file an Exchange Offer Registration Statement with the SEC on or prior to 90
days after the Closing, (2) Panhandle will use its best efforts to have the
Exchange Offer Registration Statement declared effective by the SEC on or prior
to 180 days after the Closing Date, (3) unless the Exchange Offer would not be
permitted by applicable law or SEC policy, Panhandle will commence the Exchange
Offer and use its best efforts to issue on or prior to 30 business days after
the date on which the Exchange Offer Registration Statement was declared
effective by the SEC, Exchange Notes in exchange for all Notes tendered prior
thereto in the Exchange Offer and (4) if obligated to file the Shelf
Registration Statement, Panhandle will file the Shelf Registration Statement
with the SEC on or prior to 60 days after such filing obligation arises and to
use its best efforts to cause the Shelf Registration to be declared effective by
the SEC on or prior to 120 days after the date on which Panhandle becomes
obligated to file such Shelf Registration Statement. Except as provided in the
next paragraph, if (a) Panhandle fails to file any of the Registration
Statements required by the Registration Rights Agreement on or before the date
specified for such filing, (b) any of such Registration Statements are not
declared effective by the SEC on or prior to the date specified for such
effectiveness (the "EFFECTIVENESS TARGET DATE"), (c) Panhandle fails to
consummate the Exchange Offer within 30 business days after the Registration
Statement is first declared effective with respect to the Exchange Offer
Registration Statement or (d) the Shelf Registration Statement or the Exchange
Offer Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (a) through (d) above being a "Registration
Default"), then Panhandle will pay liquidated damages to each holder of Notes,
with respect to the first 90-day period immediately following the occurrence of
the first Registration Default in an amount equal to $0.05 per week per $1,000
principal amount of Notes held by such holder. The amount of the Liquidated
Damages will increase by an additional $0.05 per week per $1,000 principal
amount of Notes with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.25 per week per $1,000 principal amount of Notes. All accrued
Liquidated Damages will be paid by Panhandle on each interest payment date to
the Depositary by wire transfer of immediately available funds or by federal
funds check and to holders of certificated securities by mailing checks to their
registered addresses. Following the cure of all Registration Defaults the
accrual of Liquidated Damages will cease.

     Holders of Notes will be required to make certain representations to
Panhandle (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver information to
be used in connection with the Shelf Registration Statement and to provide
comments on the Shelf Registration Statement within the time periods set forth
in the Registration Rights Agreement in order to have

                                       33
<PAGE>   37

their Notes included in the Shelf Registration Statement and benefit from the
provisions regarding Liquidated Damages set forth above.

     Any Notes that remain outstanding after the consummation of the Exchange
Offer, together with all Exchange Notes issued in connection with the Exchange
Offer, will be treated as a single series of securities under the Indenture.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION

     The term "EXPIRATION DATE" shall mean September 1, 1999, unless Panhandle,
in its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date to which the Exchange Offer is
extended.

     To extend the Expiration Date, Panhandle will notify the Exchange Agent of
any extension by oral or written notice and will notify the holders of the
Exchange Notes by means of a press release or other public announcement prior to
9:00 a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Such announcement may state that Panhandle is
extending the Exchange Offer for a specified period of time.

     Panhandle reserves the right (i) to delay acceptance of any Notes, to
extend the Exchange Offer or to terminate the Exchange Offer and not permit
acceptance of Notes not previously accepted if any of the conditions set forth
herein under "-- Conditions" shall have occurred and shall not have been waived
by Panhandle, by giving oral or written notice of such delay, extension or
termination to the Exchange Agent, or (ii) to amend the terms of the Exchange
Offer in any manner deemed by it to be advantageous to the holders of the Notes.
Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
Exchange Agent. If the Exchange Offer is amended in a manner determined by
Panhandle to constitute a material change, Panhandle will promptly disclose such
amendment in a manner reasonably calculated to inform the holders of the Notes
of such amendment.

     Without limiting the manner in which Panhandle may choose to make public
announcement of any delay, extension, amendment or termination of the Exchange
Offer, Panhandle shall have no obligations to publish, advertise, or otherwise
communicate any such public announcement, other than by making a timely release
to an appropriate news agency.

INTEREST ON THE EXCHANGE NOTES

     The Exchange Notes will accrue interest for the 2004 Exchange Notes at a
rate of 6.125% per annum, for the 2009 Exchange Notes at a rate of 6.500% per
annum and for the 2029 Exchange Notes at a rate of 7.000% per annum. Interest on
the Exchange Notes will accrue from the last date on which interest was paid on
the Notes, or, if no interest has been paid on such Notes, from March 29, 1999,
the date of issuance of the Notes for which the Exchange Offer is being made.
Interest on the 2004 Exchange Notes is payable semiannually on March 15 and
September 15, commencing on September 15, 1999. Interest on the 2009 and 2029
Exchange Notes is payable semiannually on January 15 and July 15 each year
commencing January 15, 2000.

PROCEDURES FOR TENDERING

     To tender in the Exchange Offer, a holder must complete, sign and date the
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
medallion guaranteed if required by the Letter of Transmittal, and mail or
otherwise deliver such Letter of Transmittal or such facsimile, together with
any other required documents, to the Exchange Agent prior to 5:00 p.m., New York
City time, on the Expiration Date. In addition, either (i) a timely confirmation
of a book-entry transfer (a "BOOK-ENTRY CONFIRMATION") of such Notes into the
Exchange Agent's account at The Depositary (the "BOOK-ENTRY TRANSFER FACILITY")
pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date or (ii) the holder
must comply with the guaranteed delivery procedures described below. THE METHOD
OF DELIVERY OF LETTERS OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE
EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDERS. IF SUCH DELIVERY IS
BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE TIMELY DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO
LETTERS OF TRANSMITTAL OR OTHER REQUIRED DOCUMENTS SHOULD BE SENT TO PANHANDLE.
Delivery of all documents must be made to the Exchange Agent at its address set
forth below. Holders may also request their respective brokers, dealers,
commercial banks, trust companies or nominees to effect such tender for such
holders.

     The tender by a holder of Notes will constitute an agreement between such
holder and Panhandle in accordance with the terms and subject to the conditions
set forth herein and in the Letter of Transmittal. Any beneficial owner whose
Notes are registered in the name of a broker, dealer, commercial bank, trust
company or other nominee and who wishes to tender should contact such registered
holder promptly and instruct such registered holder to tender on his behalf.

     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be medallion guaranteed by any member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor" institution within
the meaning of Rule 17Ad-15 under the Exchange Act (each an "ELIGIBLE
INSTITUTION") unless the Notes tendered pursuant thereto are tendered for the
account of an Eligible Institution.

     If the Letter of Transmittal is signed by trustees, executors,
administrators, guardians, attorneys-in-fact, officers of corporations, or
others acting in a fiduciary or representative capacity, such person should so
indicate when signing, and unless waived by Panhandle, evidence satisfactory to
Panhandle of their authority to so act must be submitted with the Letter of
Transmittal.

     All questions as to the validity, form, eligibility (including time of
receipt) and withdrawal of the tendered Notes will be determined by Panhandle,
in its sole discretion, which determination will be final and binding. Panhandle
reserves the absolute right to reject any and all Notes not properly tendered or
any Notes which, if accepted, would, in the opinion of counsel for Panhandle, be
unlawful. Panhandle also reserves the absolute right to waive any irregularities
or conditions of tender as to particular Notes. Panhandle's interpretation of
the terms and conditions of the Exchange Offer (including the

                                       35
<PAGE>   39

instructions in the Letter of Transmittal) will be final and binding on all
parties. Unless waived, any defects or irregularities in connection with tenders
of Notes must be cured within such time as Panhandle shall determine. Neither
Panhandle, the Exchange Agent nor any other person shall be under any duty to
give notification of defects or irregularities with respect to tenders of Notes,
nor shall any of them incur any liability for failure to give such notification.
Tenders of Notes will not be deemed to have been made until such irregularities
have been cured or waived. Any Notes received by the Exchange Agent that are not
properly tendered and as to which the defects or irregularities have not been
cured or waived will be returned without cost to such holder by the Exchange
Agent, unless otherwise provided in the Letter of Transmittal, as soon as
practicable following the Expiration Date.

     In addition, Panhandle reserves the right, in its sole discretion, subject
to the provisions of the Indenture, to purchase or make offers for any Notes
that remain outstanding subsequent to the Expiration Date or, as set forth under
"-- Conditions," to terminate the Exchange Offer in accordance with the terms of
the Registration Rights Agreement, and to the extent permitted by applicable
law, purchase Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the terms
of the Exchange Offer.

ACCEPTANCE OF NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
all Notes properly tendered will be accepted promptly after the Expiration Date,
and the Exchange Notes will be issued promptly after acceptance of the Notes.
See "-- Conditions." For purposes of the Exchange Offer, Notes shall be deemed
to have been accepted as validly tendered for exchange when, as and if Panhandle
has given oral or written notice thereof to the Exchange Agent.

     In all cases, issuance of Exchange Notes for Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of a Book-Entry Confirmation of such Notes into the
Exchange Agent's account at the Book-Entry Transfer Facility, a properly
completed and duly executed Letter of Transmittal and all other required
documents. If any tendered Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer, such unaccepted or such
nonexchanged Notes will be credited to an account maintained with such Book-
Entry Transfer Facility as promptly as practicable after the expiration or
termination of the Exchange Offer.

BOOK-ENTRY TRANSFER

     The Exchange Agent will make a request to establish an account with respect
to the Notes at the Book-Entry Transfer Facility for purposes of the Exchange
Offer within two business days after the date of this Prospectus. Any financial
institution that is a participant in the Book-Entry Transfer Facility's systems
may make book-entry delivery of Notes by causing the Book-Entry Transfer
Facility to transfer such Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for transfer. However, the Letter of Transmittal (or
facsimile) thereof with any required signature guarantees and any other required
documents must, in any case, be transmitted to and received by the Exchange
Agent at

                                       36
<PAGE>   40

one of the addresses set forth under "-- Exchange Agent" on or prior to the
Expiration Date or the guaranteed delivery procedures described below must be
complied with.

GUARANTEED DELIVERY PROCEDURES

     If the procedures for book-entry transfer cannot be completed on a timely
basis, a tender may be effected if (i) the tender is made through an Eligible
Institution, (ii) prior to the Expiration Date, the Exchange Agent receives from
such Eligible Institution a properly completed and duly executed Letter of
Transmittal (or a facsimile thereof) and Notice of Guaranteed Delivery,
substantially in the form provided by Panhandle (by facsimile transmission, mail
or hand delivery), setting forth the name and address of the holder of Notes and
the amount of Notes tendered, stating that the tender is being made thereby and
guaranteeing that within three New York Stock Exchange, Inc. ("NYSE') trading
days after the date of execution of the Notice of Guaranteed Delivery, a Book-
Entry Confirmation and any other documents required by the Letter of Transmittal
will be deposited by the Eligible Institution with the Exchange Agent, and (iii)
a Book-Entry Confirmation and all other documents required by the Letter of
Transmittal are received by the Exchange Agent within three NYSE trading days
after the date of execution of the Notice of Guaranteed Delivery.

WITHDRAWAL OF TENDERS

     Tenders of Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.

     For a withdrawal to be effective, a written notice of withdrawal must be
received by the Exchange Agent prior to 5:00 p.m., New York City time, on the
Expiration Date at one of the addresses set forth under "-- Exchange Agent." Any
such notice of withdrawal must specify the name and number of the account at the
Book-Entry Transfer Facility from which the Notes were tendered, identify the
principal amount of the Notes to be withdrawn, and specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Notes and otherwise comply with the procedures of such Book-Entry
Transfer Facility. All questions as to the validity, form and eligibility
(including time of receipt) of such notice will be determined by Panhandle,
whose determination shall be final and binding on all parties. Any Notes so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Notes which have been tendered for exchange
but which are not exchanged for any reason will be credited to an account
maintained with such Book-Entry Transfer Facility for the Notes as soon as
practicable after withdrawal, rejection of tender or termination of the Exchange
Offer. Properly withdrawn Notes may be retendered by following one of the
procedures described under "-- Procedures for Tendering" and "-- Book-Entry
Transfer" at any time on or prior to the Expiration Date.

CONDITIONS

     Notwithstanding any other term of the Exchange Offer, Notes will not be
required to be accepted for exchange, nor will Exchange Notes be issued in
exchange for any Notes, and Panhandle may terminate or amend the Exchange Offer
as provided herein before the acceptance of such Notes, if, because of any
change in law, or applicable interpretations thereof by the SEC, Panhandle
determines that it is not permitted to effect the Exchange Offer. Panhandle has
no obligation to, and will not knowingly, permit acceptance of

                                       37
<PAGE>   41

tenders of Notes from affiliates of Panhandle or from any other holder or
holders who are not eligible to participate in the Exchange Offer under
applicable law or interpretations thereof by the Staff of the SEC, or if the
Exchange Notes to be received by such holder or holders of Notes in the Exchange
Offer, upon receipt, will not be tradable by such holder without restriction
under the Securities Act and the Exchange Act and without material restrictions
under the "blue sky" or securities laws of substantially all of the states of
the United States.

EXCHANGE AGENT

     Bank One Trust Company, NA has been appointed as Exchange Agent for the
Exchange Offer. Questions and requests for assistance and requests for
additional copies of this Prospectus or of the Letter of Transmittal should be
directed to the Exchange Agent addressed as follows:

  By Mail (Certified, Registered, Overnight or First Class) or Hand Delivery:

                           Bank One Trust Company, NA
                  c/o First Chicago Trust Company of New York
                                 14 Wall Street
                              8th Floor, Window 2
                            New York, New York 10005

                                  By Facsimile
                        (For Eligible Institutions Only)
                                 (212) 240-8938

                                Telephone Number
                                 (212) 240-8801

FEES AND EXPENSES

     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by Panhandle. The principal solicitation for tenders pursuant to the
Exchange Offer is being made by mail; however, additional solicitations may be
made by telegraph, telephone, telecopy or in person by officers and regular
employees of Panhandle.

     Panhandle will not make any payments to brokers, dealers or other persons
soliciting acceptances of the Exchange Offer. Panhandle, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
the Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith.

     The expenses to be incurred in connection with the Exchange Offer will be
paid by Panhandle, including fees and expenses of the Exchange Agent and the
Trustee, and accounting, legal, printing and related fees and expenses.

     Panhandle will pay all transfer taxes, if any, applicable to the exchange
of Notes pursuant to the Exchange Offer. If, however, Exchange Notes or Notes
for principal amounts not tendered or accepted for exchange are to be registered
or issued in the name of any person other than the registered holder of the
Notes tendered, or if tendered Notes are registered in the name of any person
other than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes

                                       38
<PAGE>   42

(whether imposed on the registered holder or any other persons) will be payable
by the tendering holder. If satisfactory evidence of payment of such taxes or
exemption therefrom is not submitted with the Letter of Transmittal, the amount
of such transfer taxes will be billed directly to such tendering holder.

RESALE OF EXCHANGE NOTES

     Based on an interpretation by the staff of the SEC set forth in no-action
letters issued to third parties, Panhandle believes that Exchange Notes issued
pursuant to the Exchange Offer in exchange for Notes may be offered for resale,
resold and otherwise transferred by any owner of such Exchange Notes (other than
any such owner which is an "affiliate" of Panhandle within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such
Exchange Notes are acquired in the ordinary course of such owner's business and
such owner does not intend to participate, and has no arrangement or
understanding with any person to participate, in the distribution of such
Exchange Notes. Any owner of Notes who tenders in the Exchange Offer with the
intention to participate, or for the purpose of participating, in a distribution
of the Exchange Notes may not rely on the position of the staff of the SEC
enunciated in Exxon Capital Holdings Corporation (available May 13, 1998, as
interpreted in the SEC's letter to Shearman & Sterling dated July 2, 1993),
Morgan Stanley & Co., Incorporated (available June 5, 1991), Warnaco, Inc.
(available June 5, 1991), and Epic Properties, Inc. (available October 21, 1991)
or similar no-action letters (collectively the "NO-ACTION LETTERS") but rather
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. In addition, any such
resale transaction should be covered by an effective registration statement
containing the selling security holders information required by Item 507 of
Regulation S-K of the Securities Act. Each broker-dealer that receives Exchange
Notes for its own account in exchange for Notes, where such Notes were acquired
by such broker-dealer as a result of market-making activities or other trading
activities, may be a statutory underwriter and must acknowledge that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such Exchange Notes.

     By tendering in the Exchange Offer, each Holder (or DTC participant, in the
case of tenders of interests in the Global Notes held by DTC) will represent to
Panhandle (which representation may be contained the Letter of Transmittal) to
the effect that (A) it is not an affiliate of Panhandle, (B) it is not engaged
in, and does not intend to engage in, and has no arrangement or understanding
with any person to participate in, a distribution of the Exchange Notes to be
issued in the Exchange Offer and (C) it is acquiring the Exchange Notes in its
ordinary course of business. Each Holder will acknowledge and agree that any
broker-dealer and any such Holder using the Exchange Offer to participate in a
distribution of the Exchange Notes acquired in the Exchange Offer (1) could not
under SEC policy as in effect on the date of the Registration Rights Agreement
rely on the position of the SEC enunciated in the No-Action Letters, and (2)
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction and that such a
secondary resale transaction must be covered by an effective registration
statement containing the selling security holder information required by Item
507 or 508, as applicable, of Regulation S-K if the resales are of Exchange
Notes obtained by such Holder in exchange for Notes acquired by such Holder
directly from Panhandle or an affiliate thereof.

                                       39
<PAGE>   43

     To comply with the securities laws of certain jurisdictions, it may be
necessary to qualify for sale or to register the Exchange Notes prior to
offering or selling such Exchange Notes. Panhandle has agreed, pursuant to the
Registration Rights Agreement and subject to certain specified limitations
therein, to cooperate with selling Holders or underwriters in connection with
the registration and qualification of the Exchange Notes for offer or sale under
the securities or "blue sky" laws of such jurisdictions as may be necessary to
permit the holders of Exchange Notes to trade the Exchange Notes without any
restrictions or limitations under the securities laws of the several states of
the United States.

CONSEQUENCES OF FAILURE TO EXCHANGE

     Holders of Notes who do not exchange their Notes for Exchange Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Notes as set forth in the legend thereon as a consequence of
the issuance of the Notes pursuant to exemptions from, or in transactions not
subject to, the registration requirements of the Securities Act and applicable
state securities laws. In general, the Notes may not be registered under the
Securities Act, except pursuant a transaction not subject to, the Securities Act
and applicable state securities laws. Panhandle does not currently anticipate
that it will register the Notes under the Securities Act. To the extent that
Notes are tendered and accepted in the Exchange Offer, the trading market for
untendered and tendered but unaccepted Notes could be adversely affected.

             CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

DESCRIPTION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OF NOTES
FOR EXCHANGE NOTES

     The following summary describes the principal United States federal income
tax consequences to holders who exchange Notes for Exchange Notes pursuant to
the Exchange Offer. This summary is intended to address the beneficial owners of
Notes that are citizens or residents of the United States, corporations,
partnerships or other entities created or organized in or under the laws of the
United States or any State or the District of Columbia, or estates or trusts
that are not foreign estates or trusts for United States federal income tax
purposes, in each case, that hold the Notes as capital assets.

     The exchange of Notes for Exchange Notes pursuant to the Exchange Offer
will not constitute a taxable exchange for United States federal income tax
purposes. As a result, a holder of a Note whose Note is accepted in the Exchange
Offer will not recognize gain or loss on the exchange. A tendering holder's tax
basis in the Exchange Notes received pursuant to the Exchange Offer will be the
same as such holder's tax basis in the Notes surrendered therefor. A tendering
holder's holding period for the Exchange Notes received pursuant to the Exchange
Offer-will include its holding period for the Notes surrendered therefor.

     ALL HOLDERS OF NOTES ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE UNITED STATES FEDERAL, STATE AND LOCAL TAX CONSEQUENCES OF THE
EXCHANGE OF NOTES FOR EXCHANGE NOTES, AND OF THE OWNERSHIP AND DISPOSITION OF

                                       40
<PAGE>   44

EXCHANGE NOTES RECEIVED IN THE EXCHANGE OFFER IN LIGHT OF THEIR OWN PARTICULAR
CIRCUMSTANCES.

DESCRIPTION OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN THE
EXCHANGE NOTES

     The following is a summary of the material United States federal income tax
consequences of the acquisition, ownership and disposition of the Notes or the
Exchange Notes by a United States Holder (as defined below). This summary deals
only with the United States Holders that will hold the Notes or the Exchange
Notes as capital assets. The discussion does not cover-all aspects of federal
taxation that may be relevant to, or the actual tax effect that any of the
matters described herein will have on, the acquisition, ownership or disposition
of the Notes or the Exchange Notes by particular investors, and does not address
state, local, foreign or other tax laws. In particular, this summary does not
discuss all of the tax considerations that may be relevant to certain types of
investors subject to special treatment under the federal income tax laws (such
as banks, insurance companies, investors liable for the alternative minimum tax,
individual retirement accounts and other tax-deferred accounts, tax-exempt
organizations, dealers in securities or currencies, investors that will hold the
Notes or the Exchange Notes as part of straddles, hedging transactions or
conversion transactions for federal tax purposes or investors whose functional
currency is not United States Dollars). Furthermore, the discussion below is
based on provisions of the Internal Revenue Code of 1986, as amended, and
regulations, rulings, and judicial decisions thereunder as of the date hereof,
and such authorities may be repealed, revoked or modified so as to result in
U.S. federal income tax consequences different from those discussed below.

     PERSONS CONSIDERING THE PURCHASE, OWNERSHIP, OR DISPOSITION OF EXCHANGE
NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME
TAX CONSEQUENCES IN LIGHT OF THEIR PARTICULAR SITUATIONS AS WELL AS ANY
CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR INTERNATIONAL TAXING
JURISDICTION.

     As used herein, the term "UNITED STATES HOLDER" means a beneficial owner of
the Notes or the Exchange Notes that is (i) a citizen or resident of the United
States for United States federal income tax purposes, (ii) a corporation created
or organized under the laws of the United States or any State thereof, (iii) a
person or entity that is otherwise subject to United States federal income tax
on a net income basis in respect of income derived from the Notes or the
Exchange Notes, or (iv) a partnership to the extent the interest therein is
owned by a person who is described in clause (i), (ii) or (iii) of this
paragraph.

INTEREST

     Interest paid on a Note or an Exchange Note will be taxable to a United
States Holder as ordinary income at the time it is received or accrued,
depending on the holder's method of accounting for tax purposes.

                                       41
<PAGE>   45

PURCHASE, SALE, EXCHANGE, RETIREMENT AND REDEMPTION OF THE EXCHANGE NOTES

     In general (with certain exceptions described below) a United States
Holder's tax basis in an Exchange Note will equal the price paid for the Notes
for which such Exchange Note was exchanged pursuant to the Exchange Offer. A
United States Holder generally will recognize gain or loss on the sale,
exchange, retirement, redemption or other disposition of a Note or an Exchange
Note (or portion thereof) equal to the difference between the amount realized on
such disposition and the United States Holder's tax basis in the Note or the
Exchange Note (or portion thereof). Except to the extent attributable to accrued
but unpaid interest, gain or loss recognized on such disposition of a Note or an
Exchange Note will be capital gain or loss. Under the "Taxpayer Relief Act of
1997" (the "TAXPAYER ACT") the maximum rate applicable to long-term capital
gains of individuals has been reduced to 20%. However, the Taxpayer Act also
extends the holding period for long-term capital gains to 18 months for capital
assets disposed of after July 28, 1997. Gain on capital assets held between 12
months and 18 months are subject to tax at a maximum rate of 28%. Any such gain
will generally be United States source gain.

BOND PREMIUM

     If a United States Holder acquires an Exchange Note or has acquired a Note,
in each case, for an amount more than its redemption price, the Holder may elect
to amortize such bond premium on a yield to maturity basis. Once made, such an
election applies to all bonds (other than bonds the interest on which is
excludable from gross income) held by the United States Holder at the beginning
of the first taxable year to which the election applies or thereafter acquired
by the United States Holder, unless the IRS consents to a revocation of the
election. The basis of an Exchange Note will be reduced by any amortizable bond
premium taken as a deduction.

MARKET DISCOUNT

     The purchase of an Exchange Note or the purchase of a Note other than at
original issue may be affected by the market discount provisions of the Code.
These rules generally provide that, subject to a statutorily defined de minimis
exception, if a United States Holder purchases an Exchange Note (or purchased a
Note) at a "market discount," as defined below, and thereafter recognizes gain
upon a disposition of the Exchange Note (including dispositions by gift or
redemption), the lesser of such gain (or appreciation, in the case of a gift) or
the portion of the market discount that has accrued ("ACCRUED MARKET DISCOUNT")
while the Exchange Note (and its predecessor Note, if any) was held by such
United States Holder will be treated as ordinary interest income at the time of
disposition rather than as capital gain. For an Exchange Note or a Note, "MARKET
DISCOUNT" is the excess of the stated redemption price at maturity over the tax
basis immediately after its acquisition by a United States Holder. Market
discount generally will accrue ratably during the period from the date of
acquisition to the maturity date of the Exchange Note, unless the United States
Holder elects to accrue such discount on the basis of the constant yield method.
Such an election applies only to the Exchange Note with respect to which it is
made and is irrevocable.

     In lieu of including the accrued market discount income at the time of
disposition, a United States Holder of an Exchange Note acquired at a market
discount (or acquired in exchange for a Note acquired at a market discount) may
elect to include the accrued market discount in income currently either ratably
or using the constant yield method.

                                       42
<PAGE>   46

Once made, such an election applies to all other obligations that the United
States Holder purchases at a market discount during the taxable year for which
the election is made and in all subsequent taxable years of the United States
Holder, unless the Internal Revenue Service consents to a revocation of the
election. If an election is made to include accrued market discount in income
currently, the basis of an Exchange Note (or, where applicable, a predecessor
Note) in the hands of the United States Holder will be increased by the accrued
market discount thereon as it is includible in income. A United States Holder of
a market discount Exchange Note who does not elect to include market discount in
income currently generally will be required to defer deductions for interest on
borrowings allocable to such Exchange Note, if any, in an amount not exceeding
the accrued market discount on such Exchange Note until the maturity or
disposition of such Exchange Note.

BACKUP WITHHOLDING AND INFORMATION REPORTING

     Payments of interest and principal on, and the proceeds of sale or other
disposition of the Notes or the Exchange Notes payable to a United States
Holder, may be subject to information reporting requirements and backup
withholding at a rate of 31% will apply to such payments if the United States
Holder fails to provide an accurate taxpayer identification number or to report
all interest and dividends required to be shown on its federal income tax
returns. Certain United States Holders (including, among others, corporations)
are not subject to backup withholding. United States Holders should consult
their tax advisors as to their qualification for exemption from backup
withholding and the procedure for obtaining such an exemption.

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Notes for its own account
pursuant the Exchange Offer must acknowledge that it will deliver a prospectus
in connection with any resale of such Exchange Notes. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer in
connections with resales of the Exchange Notes received in exchange for the
Notes where such Notes were acquired as a result of market-making activities or
other trading activities. Panhandle has agreed that, starting on the Expiration
Date and ending on the close of business on the first anniversary of the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale.

     Panhandle will not receive any proceeds from any sale of the Exchange Notes
by broker-dealers. The Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the counter market, in negotiated transaction,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices or negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"UNDERWRITER" within the meaning of the Securities Act and any profit of any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that

                                       43
<PAGE>   47

by acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "UNDERWRITER"within the
meaning of the Securities Act.

     For a period of one year after the Expiration Date, Panhandle will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. Panhandle has agreed to pay all expenses incident to the
Exchange Offer and will indemnify the holders of the Exchange Notes against
certain liabilities, including liabilities under the Securities Act.

                                 LEGAL MATTERS

     Opinions as to the legality of the Exchange Notes will be rendered for
Panhandle by Michael D. Van Hemert, Assistant General Counsel for CMS Energy. As
of March 31, 1999, Mr. Van Hemert beneficially owned approximately 2,889 shares
of CMS Energy Common Stock.

                                    EXPERTS

     The financial statements incorporated in this Prospectus by reference from
Panhandle's Annual Report on Form 10-K have been audited by Deloitte & Touche
LLP, independent auditors, as stated in their report, which is incorporated
herein by reference, and have been so incorporated in reliance upon the report
of such firm given upon their authority as experts in accounting and auditing.

     The consolidated financial statements of Panhandle, for the year ended
December 31, 1996, incorporated by reference in this Prospectus, have been
audited by KPMG LLP, independent certified public accountants, as indicated in
their report thereon. Such financial statements have been incorporated by
reference in reliance upon the reports of KPMG LLP.

     With respect to the unaudited interim consolidated financial information
for the period ended March 31, 1999 Arthur Andersen LLP has applied limited
procedures in accordance with professional standards for a review of such
information. However, their separate report thereon states that they did not
audit and they did not express an opinion on that interim consolidated financial
information. Accordingly, the degree of reliance on their report on that
information should be restricted in light of the limited nature of the review
procedures applied. In addition, the accountants are not subject to the
liability provisions of Section 11 of the Securities Act, for their reports on
the unaudited interim consolidated financial information because those reports
are not a "REPORT" or "PART" of the registration statement prepared or certified
by the accountants within the meaning of Sections 7 and 11 of the Securities
Act.

     Future consolidated financial statements of Panhandle and the reports
thereon of Arthur Andersen LLP also will be incorporated by reference in this
Prospectus in reliance upon the authority of that firm as experts in giving
those reports to the extent that said firm has audited said consolidated
financial statements and consented to the use of their reports thereon.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                     OF PANHANDLE EASTERN PIPE LINE COMPANY

     The following Unaudited Pro Forma Combined Financial Statements (the "PRO
FORMA FINANCIAL STATEMENTS") of Panhandle Eastern Pipe Line Company illustrate
the effects of: (1) various restructuring, realignment, and elimination of
activities between the Panhandle Companies (as defined below) and Duke Energy
Corporation and its subsidiaries ("DUKE ENERGY") prior to the closing of the
acquisition (the "ACQUISITION") of Panhandle Eastern Pipe Line Company
("PANHANDLE") and its principal subsidiaries, Trunkline Gas Company and Pan Gas
Storage Company, and its affiliates Panhandle Storage Company and Trunkline LNG
Company (collectively, the "PANHANDLE COMPANIES") by CMS Energy Corporation
("CMS Energy"); (2) the adjustments resulting from the Acquisition by CMS
Energy; and (3) the public issuance of $800 million of Notes by CMS Panhandle
Holding Company (the "NOTES") ("CMS HOLDING") which were completed to facilitate
the Acquisition (the "Financing Transaction"). The $1.1 billion balance of the
cash purchase price was paid with an equity contribution from CMS Energy. The
Unaudited Pro Forma Combined Balance Sheets have been prepared as if such
transactions occurred on the balance sheet date; the Unaudited Pro Forma
Combined Income Statements have been prepared as if such transactions occurred
as of January 1, 1998.

     The Pro Forma Financial Statements reflect CMS Energy acquiring all of the
common stock of the Panhandle Companies. The Pro Forma Financial Statements also
reflect, prior to the Acquisition, the transfer of Panhandle's interest in
Northern Border Pipeline Company and certain non-operating assets to other
subsidiaries of Duke Energy, and the elimination of certain intercompany
accounts, including advances, between Panhandle and Duke Energy. The purchase
price for the common stock of the Panhandle Companies was $1.9 billion in cash.
The Panhandle Companies will have approximately $1.1 billion of debt outstanding
after the closing of the Acquisition. This indebtedness includes approximately
$300 million of existing debt and the debt incurred in the Financing
Transaction. CMS Energy's acquisition of the Panhandle Companies was accounted
for under the purchase method.

     A final determination of required purchase accounting adjustments,
including the allocation of the purchase price to the assets acquired and
liabilities assumed based on their respective fair values, and the final
determination of estimated remaining useful lives of the acquired property,
plant and equipment, have not yet been made. Accordingly, the pro forma
accounting adjustments made in connection with the development of the Pro Forma
Financial Statements are preliminary and have been made solely for purposes of
developing the pro forma combined financial information. However, CMS Energy
management believes that the pro forma adjustments and the underlying
assumptions reasonably present the significant effects of the Acquisition and
the Financing Transactions. In addition, CMS Energy will undertake studies to
determine the fair value of assets and liabilities and estimated remaining
useful lives of the acquired property, plant and equipment of the Panhandle
Companies and will revise the accounting adjustments upon completion of those
studies. The actual financial position and results of operations of the combined
entity will differ, perhaps significantly, from the pro forma amounts reflected
herein because of a variety of factors, including access to additional
information, changes in value and changes in operating results between the dates
of the Pro Forma Financial Statements and the Acquisition date. The Pro Forma
Financial Statements are not

                                       F-1
<PAGE>   49

necessarily indicative of actual operating results or financial position had the
Acquisition and the Financing Transactions occurred as of the dates indicated
above, nor do they purport to indicate operating results or financial position
which may be attained in the future.

     The significant adjustments to pro forma net income reflect (1) higher
depreciation and amortization expense to give effect to the allocation of excess
purchase price amortized over 40 years and the fair value of net assets acquired
related to property, plant and equipment prospectively depreciated over a
revised estimated average remaining life of 40 years, (2) elimination of pension
and rental income, and (3) lower interest expense from the cancellation of
certain indebtedness between Panhandle and Duke Energy and additional interest
expense reflecting the new debt issuance of CMS Holding.

     The significant adjustments to the pro forma financial position reflect (1)
elimination of the advances to Duke Energy and the notes payable to Duke Energy,
(2) increases to property, plant and equipment and accrued liabilities for the
purchase price allocation, (3) recognition of goodwill in the fair value
calculation, (4) decreases in taxes and other liabilities assumed by Duke
Energy, and (5) increases in long-term debt and common stockholder's equity in
connection with the Acquisition and the Financing Transactions.

     The Panhandle Companies' financial statements utilized in the preparation
of the Pro Forma Financial Statements are based upon financial statements and
information obtained from Duke Energy and Panhandle.

     The Pro Forma Financial Statements should be read in conjunction with the
historical financial statements and notes thereto of Panhandle included in
Panhandle's annual report on Form 10-K for the year ended December 31, 1998
delivered with this Prospectus and the documents incorporated by reference
herein, and the notes to the Pro Forma Financial Statements included elsewhere
herein. The pro forma adjustments do not reflect any potential operating
efficiencies or cost savings which management believes may be achievable with
respect to the combined companies.

RESTRUCTURING AND REALIGNMENT:

     (a) To reflect the results of operations of Panhandle Storage Company and

                              AS OF MARCH 31, 1999

ACQUISITION ADJUSTMENTS:

     (a) To reflect the increase in property, plant and equipment to adjust the
historical value of these assets to their estimated fair values. The allocation
reflects CMS Energy's internal evaluation of the excess purchase price and is
subject to the completion of a study to determine the fair value of the
property. Should the study not support such allocation to property, plant and
equipment, the excess of total purchase price over the fair value of the net
assets acquired will be reflected as an adjustment to the preliminary estimate
of goodwill.

     (b) To reflect the preliminary estimated acquisition adjustments under the
purchase method of accounting to record assets acquired and liabilities assumed
at estimated fair value for (i) the preliminary estimate of goodwill, (ii) the
increase of certain other assets, (iii) the elimination of previously recorded
regulatory assets assuming Panhandle ceases to apply Statement of Financial
Accounting Standards No. 71 accounting for its regulated assets, (iv) the
long-term debt assumed, (v) the assumption of benefit plan obligations by the
Panhandle Companies, previously assumed by Duke Energy, and (vi) the accrual of
certain obligations of the Panhandle Companies which are expected to be paid
after completion of the transaction. The following adjustments reflect CMS
Energy management's intended business strategies and outlook which may differ
from the business strategies and outlook of Duke Energy management prior to the
Acquisition:

              NOTES TO UNAUDITED PRO FORMA COMBINED BALANCE SHEET
                            AS OF DECEMBER 31, 1998

RESTRUCTURING AND REALIGNMENT:

     (a) To reflect the financial position of Panhandle Storage Company and
Trunkline LNG Company, both acquired by CMS Energy, and the transfer of
Panhandle's interest in Northern Border Pipeline Company and certain
non-operating assets to other subsidiaries of Duke Energy under the provisions
of the Stock Purchase Agreement.

ELIMINATION OF DUKE ENERGY ACTIVITIES:

     (b) To reflect the settlement of the advances and notes receivable from
Duke Energy under the provisions of the Stock Purchase Agreement.

     (c) To reflect the transfer from the Panhandle Companies to Duke Energy of
certain environmental and litigation liabilities and the related assets under
the provisions of the Stock Purchase Agreement.

     (d) To reflect the transfer to Duke Energy of certain assets, primarily an
office building, under the provisions of the Stock Purchase Agreement.

     (e) To reflect the settlement of certain short-term notes payable to Duke
Energy under the provisions of the Stock Purchase Agreement.

     (f) To reflect the transfer from the Panhandle Companies to Duke Energy of
all tax liabilities under the provisions of the Stock Purchase Agreement.

     (g) To reflect the settlement and transfer of certain assets and
liabilities described in pro forma adjustments (b) through (f).

ACQUISITION ADJUSTMENTS:

     (h) To reflect the increase in property, plant and equipment to adjust the
historical value of these assets to their estimated fair values. The allocation
reflects CMS Energy's internal evaluation of the excess purchase price and is
subject to the completion of a study to determine the fair value of the
property. Should the study not support such allocation to property, plant and
equipment, the excess of total purchase price over the fair value of the net
assets acquired will be reflected as an adjustment to the preliminary estimate
of goodwill.

     (i) To reflect the elimination of deferred credits associated with a
Trunkline LNG Company rate settlement.

     (j) To reflect the preliminary estimated acquisition adjustments under the
purchase method of accounting to record assets acquired and liabilities assumed
at estimated fair value for (i) the preliminary estimate of goodwill, (ii) the
increase of certain other assets, (iii) the elimination of previously recorded
regulatory assets, assuming Panhandle ceases to apply Statement of Financial
Accounting Standards No. 71 accounting for its regulated assets, (iv) the
long-term debt assumed, (v) the assumption of benefit plan obligations by the
Panhandle Companies, previously assumed by Duke Energy, and (vi) the accrual of
certain obligations of the Panhandle Companies which are expected to be paid
after

                                      F-11

completion of the transaction. The following adjustments reflect CMS Energy
management's intended business strategies and outlook which may differ from the
business strategies and outlook of Duke Energy management prior to the
Acquisition:
