There is excluded from this restriction:

(i) any Lien upon any property or assets of the Issuer or any Restricted Subsidiary in existence on the date of the Indenture or created pursuant to an “after-acquired property” clause or similar term in existence on the date of the Indenture or any mortgage, pledge agreement, security agreement or other similar instrument in existence on the date of the Indenture;

(ii) any Lien upon any property or assets created at the time of acquisition of such property or assets by the Issuer or any Restricted Subsidiary or within 18 months after such time to secure all or a portion of the purchase price for such property or assets or Debt incurred to finance such purchase price, whether such Debt was incurred prior to, at the time of or within 18 months of such acquisition;

(vii) any Lien in favor of the Issuer or any Restricted Subsidiary;

(viii) any Lien created or assumed by the Issuer or any Restricted Subsidiary in connection with the issuance of Debt the interest on which is excludable from gross income of the holder of such Debt pursuant to the Internal Revenue Code of 1986, as amended, or any successor statute, for the purpose of financing, in whole or in part, the acquisition or construction of property or assets to be used by the Issuer or any Subsidiary;

(x) Permitted Liens;

(xi) any Lien created by any program providing for the financing, sale or other disposition of trade or other receivables classified as current assets in accordance with United States generally accepted accounting principles entered into by the Issuer or by a Subsidiary of the Issuer, provided that such program is on terms customary for similar transactions, or any document executed by any Subsidiary of the Issuer in connection therewith, provided that such Lien is limited to the trade or other receivables in respect of which such program is created or exists, and the proceeds thereof;

(xii) any Lien upon any additions, improvements, replacements, repairs, fixtures, appurtenances or component parts thereof attaching to or required to be attached to property or assets pursuant to the terms of any mortgage, pledge agreement, security agreement or other similar instrument, creating a Lien upon such property or assets permitted by clauses (i) through (xi), inclusive, above; or

(xiii) any extension, renewal, refinancing, refunding or replacement (or successive extensions, renewals, refinancing, refundings or replacements) of any Lien, in whole or in part, that is referred to in clauses (i) through (vi), inclusive, above (and Liens related thereto referred to in clause (xii) above), or of any Debt secured thereby; provided, however, that the principal amount of Debt secured thereby shall not exceed the greater of the principal amount of Debt so secured at the time of such extension, renewal, refinancing, refunding or replacement and the original principal amount of Debt so secured (plus in each case the aggregate amount of premiums, other payments, costs and expenses paid or incurred in connection with such extension, renewal, refinancing, refunding or replacement); provided further, however, that such extension, renewal, refinancing, refunding or replacement shall be limited to all or a part of the property (including improvements, alterations and repairs on such property) subject to the encumbrance so extended, renewed, refinanced, refunded or replaced (plus improvements, alterations and repairs on such property).

Notwithstanding the foregoing, the Issuer may, and may permit any Restricted Subsidiary to, create, assume, incur, or suffer to exist any Lien upon any Principal Property to secure Debt of the Issuer or any other Person (other than the Senior Notes) that is not otherwise excepted by clauses (i) through (viii), inclusive, above without securing the Senior Notes, provided that the aggregate principal amount of all Debt then outstanding secured by such Lien and all similar Liens, together with all net sale proceeds from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by clauses (i) through (iv), inclusive, of Section 3.3(a) of this Seventh Supplemental Indenture) does not exceed the greater of 15% of Consolidated Net Tangible Assets or 15% of Total Capital.

(iii) the Issuer or such Restricted Subsidiary would be entitled to incur Debt secured by a Lien on the Principal Property subject thereto (pursuant to clauses (i) through (xiii), inclusive, of the first paragraph of Section 3.2(a) of this Seventh Supplemental Indenture) in a principal amount equal to or exceeding the net sale proceeds from the Sale-Leaseback Transaction without securing the Senior Notes; or

(iv) the Issuer 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 the Issuer or any Subsidiary of the Issuer, or (B) investment in another Principal Property or in a Subsidiary of the Issuer which owns another Principal Property.

Notwithstanding the foregoing, the Issuer may, and may permit any Restricted Subsidiary to, effect any Sale-Leaseback Transaction that is not otherwise excepted by clauses (i) through (iv), inclusive, above, provided that the net sale proceeds from such Sale-Leaseback Transaction, together with the aggregate principal amount of outstanding Debt (other than the Senior Notes) secured by Liens upon any Principal Properties not excepted by clauses (i) through (xiii), inclusive, of Section 3.2(a) of this Seventh Supplemental Indenture, do not exceed the greater of 15% of Consolidated Net Tangible Assets or 15% of Total Capital.

SECTION 3.4 Financial Information.

Whether or not required by the SEC’s rules and regulations, so long as any Senior Notes are outstanding, the Issuer shall furnish to the Holders of the Senior Notes, within the time periods specified in the SEC’s rules and regulations:

(1)

all quarterly and annual reports that would be required to be filed with the SEC on Forms 10-Q and 10-K if the Issuer was required to file such reports; and

(2)

all current reports that would be required to be filed with the SEC on Form 8-K if the Issuer was required to file such reports.

The Issuer will prepare all such reports in all material respects in accordance with all applicable rules and regulations. The Issuer will include in each annual report on Form 10-K a report on its consolidated financial statements by its certified independent public accountant. In addition, whether or not required by the SEC, the Issuer shall file a copy of each of the reports referred to in clauses (1) and (2) above with the SEC for public availability within the time periods specified in the SEC’s applicable rules and regulations (unless the SEC will not accept such a filing) and make that information available to securities analysts and prospective investors upon request.

The Issuer is currently required under the Exchange Act to file reports with the SEC. If the Issuer is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Issuer will nevertheless continue filing the reports specified in the preceding paragraphs with the SEC within the time periods specified above unless the SEC will not accept such a filing. The Issuer agrees not to take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Issuer’s filings for any reason, the Issuer will post the reports referred to in this Section 3.4 on the website ▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇ within the time periods that would apply if the Issuer was required to file those reports with the SEC.

For so long as any Senior Notes remain outstanding, at any time the Issuer is not required to file the reports required by this Section 3.4 with the SEC, the Issuer shall furnish at the Issuer’s cost to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

PANHANDLE EASTERN PIPE LINE COMPANY, LP, a Delaware limited partnership (the “Issuer”), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of One Hundred Fifty Million Dollars ($150,000,000) on June 1, 2019 (“Maturity”) and to pay interest thereon from June 2, 2009 (the “Original Issue Date”) or from the most recent interest payment date (each such date, an “Interest Payment Date”) to which interest has been paid or duly provided for, semi-annually in arrears on June 1st and December 1st in each year, commencing December 1, 2009, to the registered holders thereof on the preceding May 15th and November 15th, respectively, and at Maturity at the rate of 8.125% per annum, until the principal hereof shall have become due and payable, and on any overdue principal and premium, if any, and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on this Senior Note is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the person in whose name this Senior Note (or one or more Predecessor Securities, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment which shall be the close of business on the 15th day of the calendar month in which such Interest Payment Date occurs.

The principal of (and premium, if any) and the interest on this Senior Note shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Issuer by check mailed to the registered holder at such address as shall appear in the Security Register.

This Senior Note shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Senior Note are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

[FORM OF REVERSE OF SENIOR NOTE]

REVERSE OF SENIOR NOTE

This Senior Note is one of a duly authorized series of Securities of the Issuer (herein sometimes referred to as the “Senior Notes”), specified in the Indenture, issued or to be issued in one or more series under and pursuant to an indenture (the “Base Indenture”) dated as of March 29, 1999 among the Issuer, CMS Panhandle Holding Company, a Michigan corporation (which has merged into the Issuer), and NBD Bank, as trustee (predecessor to The Bank of New York Mellon Trust Company, N.A.), further supplemented by the Seventh Supplemental Indenture dated as of June 2, 2009 between the Issuer and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) (the Base Indenture as so supplemented, hereinafter being referred to as the “Indenture”), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Issuer and the holders of the Senior Notes. By the terms of the Indenture, the Senior Notes are issuable in series which may vary as to amount, date of maturity, rate of interest and in other respects as in the Indenture provided. This series of Senior Notes is not limited in aggregate principal amount, as specified in said Seventh Supplemental Indenture.

The Senior Notes are redeemable at the option of the Issuer at any time and from time to time, in whole or in part, upon not less than 30 days nor more than 60 days notice to each holder of such Senior Notes, at a redemption price equal to the greater of (i) 100% of the principal amount of such Senior Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus, in either 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 applicable redemption date, interest will cease to accrue on the Senior Notes or portions thereof called for redemption.

The Issuer may purchase the Senior Notes in the open market, by tender or otherwise. Senior Notes so purchased may be held, resold or surrendered to the Trustee for cancellation. If applicable, the Issuer will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and other securities laws and regulations in connection with any such purchase.

No sinking fund is provided for the Senior Notes.

If an Event of Default with respect to this Senior Note shall occur and be continuing, the principal of this Senior Note may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions for defeasance at any time of (i) the entire indebtedness of this Senior Note or (ii) certain restrictive covenants and certain other obligations with respect to this Senior Note, in each case upon compliance with certain conditions set forth therein.

The Indenture permits, with certain exceptions as therein provided, modifications and amendments of the Indenture by the Issuer and the Trustee with the consent of the holders of a majority in aggregate principal amount of the outstanding Senior Notes.

The Indenture provides that the holders of a majority in aggregate principal amount of the outstanding Senior Notes may, on behalf of all holders of Senior Notes, waive any past default under the Indenture with respect to any Senior Notes, except a default (i) in the payment of principal of, or premium, if any, or any interest on any Senior Note; or (ii) 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 Senior Note affected.

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 Indenture at the request or direction of any of the holders, unless such 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 Senior Notes have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Senior Notes; provided, however, that 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.

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

As provided in the Indenture and subject to certain limitations therein and herein set forth, the transfer of this Senior Note is registrable in the Security Register, upon surrender of this Senior Note for registration of transfer at the office or agency of the Issuer in any place where the principal of and any premium and interest on this Senior Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Issuer and the Security Registrar duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Senior Notes of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

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

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

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

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

No recourse shall be had for the payment of the principal of or the interest on this Senior Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Issuer or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

All terms used in this Senior Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.
