ITEM 5. OTHER EVENTS

On December 22, 2002, CMS Energy Corporation ("CMS Energy") announced that CMS
Gas Transmission Company ("Seller"), a wholly-owned indirect subsidiary of CMS
Energy, has entered into a definitive Stock Purchase Agreement, dated as of
December 21, 2002, (the "Agreement") with Southern Union Panhandle Corp.
("Buyer"), AIG Highstar Capital, L.P. ("Highstar"), AIG Highstar II Funding
Corp. ("Funding") and the Southern Union Company ("Southern" and collectively
with Highstar and Funding, the "Sponsors"), to sell all the outstanding
capital stock of Panhandle Eastern Pipe Line Company ("Panhandle") and its
subsidiaries, including CMS Trunkline Gas Company, CMS Trunkline LNG Company,
which operates an LNG terminal complex at Lake Charles, Louisiana, CMS
Panhandle Gas Storage, LLC and CMS Sea Robin Pipeline Company (these companies
together with certain other subsidiaries are hereinafter referred to as the
"Panhandle Companies"). The Sponsors have formed Buyer for purposes of
effecting the transactions contemplated in the Agreement. Under the terms of
the Agreement, CMS Energy will retain its indirect ownership interest in the
Centennial refined petroleum liquids pipeline, which stretches from Texas to
Illinois, and the Guardian natural gas pipeline, which serves northern
Illinois and southern Wisconsin. CMS Energy indirectly owns a one-third
interest in each and is exploring the sale of those interests.

The purchase price for the stock of the Panhandle Companies is $662 million in
cash, subject to adjustment as provided in the Agreement. The Panhandle
Companies are expected to have approximately $1.166 billion of debt outstanding
at the time of closing which will be assumed by the Buyer. Under the terms of
the Agreement, the Sponsors, severally, shall cause the Buyer to perform all of
its obligations under the Agreement which are required to be performed on or
prior to the closing, including, without limitation, Buyer's requirement to
consummate the transactions and to pay the purchase price, including any
post-closing adjustment thereto.

As previously disclosed, Panhandle plans to take a significant goodwill
impairment in 2002. Any difference between the approximate $2.4 billion
present book value of the Panhandle assets being sold and the sale price of
$1.828 billion that is not accounted for as goodwill impairment, will be
included in discontinued operations in the fourth quarter of 2002. CMS Energy
intends to use the proceeds from the sale of the Panhandle Companies to
accelerate debt reduction.



The transactions have been approved by the Board of Directors of each party to
the Agreement. The Board of Directors of CMS Energy has received separate
opinions, dated the date of the Agreement, from each of Merrill Lynch & Co. and
Salomon Smith Barney Inc. to the effect that, subject to, and based upon the
assumptions, qualifications and limitations included in such opinions, the
consideration to be received by CMS Energy pursuant to the Agreement is fair
from a financial point of view to CMS Energy.

The transactions are subject to the satisfaction or waiver of certain conditions
to closing including, without limitation, (i) the receipt of all necessary
governmental approvals and the making of all governmental filings, including the
consent or approval of certain state regulatory authorities, (ii) the filing of
the requisite notification with the Federal Trade Commission and the Department
of Justice under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended and the expiration or termination of the applicable waiting period
thereunder, (iii) the receipt of certain approvals, consents, releases and legal
and financial opinions and (iv) the filing with the Securities and Exchange
Commission ("SEC") of restated financial statements of Panhandle for each of the
fiscal years ended December 31, 2000 and December 31, 2001 (the "Annual
Financial Statements") and the restated unaudited financial statements of
Panhandle for the quarters ended March 31, 2002, June 30, 2002 and September 30,
2002 (collectively, the "Restated Financials") which, except as otherwise
described to the Buyer, shall correspond in all material respects to the draft
Restated Financials delivered to Buyer prior to the date of the Agreement, and
any footnotes with respect to such restated quarterly financial statements shall
be the same in all material respects as such footnotes in the corresponding
quarterly financial statements for Panhandle filed with the SEC, except for
corresponding changes reflected in the Annual Financial Statements.

The Agreement may be terminated under certain circumstances, including (i) by
mutual consent, (ii) by either Seller or Buyer if the closing of the
transactions have not occurred on or before June 30, 2003 (the "Termination
Date"), provided, that if the requisite regulatory approvals have been obtained
as of such date and certain other conditions shall not have been fulfilled but
are reasonably capable of being fulfilled no later than ten business days
thereafter, the Termination Date shall be extended to July 15, 2003, (iii) by
either Seller or Buyer if any mutual condition to closing shall have become
incapable of fulfillment prior to the Termination Date, as such date may be
extended, (iv) by Seller, so long as it is not then in breach of any of its
obligations under the Agreement, if either Buyer or any of the Sponsors has
breached the Agreement and the closing condition regarding the accuracy of
representations and warranties or compliance with



covenants is incapable of being cured prior to the Termination Date, as such
date may be extended, (v) by Buyer, so long as it is not then in breach of any
of its obligations under the Agreement, if Seller has breached the Agreement and
the closing condition regarding the accuracy of representations and warranties
or compliance with covenants is incapable of being cured prior to the
Termination Date, as such date may be extended, and (vi) by Seller or Buyer, if
a governmental authority issues a final order or adopts a law restraining or
prohibiting the transactions contemplated in the Agreement.

If the closing of the transactions does not occur on or prior to March 31, 2003,
a delay penalty (the "Delay Penalty") shall begin accruing on a daily basis on
April 1, 2003 and shall continue until the earlier to occur of the closing of
the transaction or the termination of the Agreement. Southern Union shall pay
the Delay Penalty to Seller which shall be calculated as follows: $100,000 per
day in April, 2003; $200,000 per day in May, 2003 and $300,000 per day on and
after June 1, 2003. The Delay penalty shall be retained by Seller whether or not
the closing occurs, provided 25% of the Delay Penalty shall be credited towards
Buyer's payment of the purchase price at closing.

The Agreement includes a post-closing indemnity period during which Seller and
Buyer shall indemnify the other and their affiliates for damages arising from
breaches of representations and warranties, covenants and, in the case of
Seller, certain other scheduled matters. The survival period for representations
and warranties generally is one year from the date of the Agreement, however
representations and warranties with respect to environmental and tax matters
survive for two years and for a period equal to the applicable statute of
limitations, respectively. Neither Seller nor Buyer shall be required to
indemnify the other for breaches of representations and warranties, other than
with respect to taxes, unless the aggregate amount of any single breach or
series of related breaches results in damages exceeding $1,000,000 and the
aggregate amount of all such damages exceed $40,000,000, in which case only
damages in excess of such amount shall be indemnified. The indemnification
obligations of both Buyer and Seller with respect to breaches of representations
and warranties, other than with respect to taxes, are capped at $200,000,000.
For purposes of determining the existence of a breach of a representation and
warranty and calculation of the amount of damages resulting from a breach, no
effect shall be given to any materiality or material adverse effect
qualifications of such representation or warranty.



The Agreement and the press release issued in connection therewith are filed
herewith as Exhibits 10.1 and 99.1, respectively, and are incorporated herein by
reference. The foregoing description of the Agreement does not purport to be
complete and is qualified in its entirety by the provisions of the Stock
Purchase Agreement.

In the event any such notice of disagreement is timely provided by Buyer, Buyer and Seller shall use their reasonable best efforts for a period of thirty (30) days (or such longer period as they may mutually agree) to resolve any disagreements with respect to the calculation of the Closing Adjustment Amount (or any element thereof).

The Auditor shall determine as promptly as practicable (but in any event within sixty (60) days) following the date on which such dispute is referred to the Auditor, based solely on written submissions, which shall be forwarded by Buyer and Seller to the Auditor within thirty (30) days following the Auditor's selection, whether the Closing Balance Sheet was prepared in accordance with the standards set forth in this Section 2.5 with respect to any items identified as disputed in the notice of disagreement and not previously resolved by Buyer and Seller, and if not, whether and to what extent (if any) the Closing Adjustment Amount (or any element thereof) requires adjustment. 18 Each party shall bear its own expenses and the fees and expenses of its own representatives and experts in connection with the preparation, review, dispute (if any) and final determination of the Closing Balance Sheet and the Closing Adjustment Amount.

The determination of the Auditor shall be final, conclusive and binding on the parties. The Auditor's determination of the amount of the Closing Adjustment Amount shall then be deemed to be the Closing Adjustment Amount for purposes of this Section 2.5. The date on which such items are accepted or finally determined in accordance with this Section 2.5 is referred as to the "DETERMINATION DATE."

Following the Closing and as soon as practicable following receipt by Seller of (i) a copy of a favorable determination letter issued by the Internal Revenue Service with respect to the Buyer Account Plan or (ii) an opinion, satisfactory to Seller's counsel, of Buyer's counsel that the Buyer Account Plan and its related trust(s) qualify under Section 401(a) and Section 501(a) of the Code, Seller shall provide each Affected Employee who is a participant in the Savings and Incentive Plan for Employees of Consumers Energy and Other CMS Energy Companies ("SELLER'S SAVINGS PLAN") with the opportunity to receive a distribution of his or her account balance and to elect to "roll over" such account balance to the Buyer Account Plan, subject to and 44 in accordance with the provisions of Seller's Savings Plan and Applicable Law.

Seller shall provide Buyer with copies of such personnel and other records of Seller pertaining to the Affected Employees and such records of any agent or representative of Seller pertaining to the Affected Employees, in each case pertaining to Seller's Savings Plan and as Buyer may reasonably request in order to administer and manage the accounts and assets rolled over to the Buyer Account Plan.

Panhandle and the Panhandle Subsidiaries shall be solely responsible (except as provided in Section 8.2(a)(iii)) for all obligations and Liabilities under each employee benefit plan listed in Section 3.12(c) of the Seller Disclosure Letter in existence as of the Closing Date, and each employee benefit plan that they establish, maintain or contribute to, on or after the Closing Date, and no such obligations or Liabilities shall be assumed or retained by Seller or its Affiliates. Seller shall retain all obligations or Liabilities and assets with respect to current and former Panhandle Employees or otherwise under all Seller Plans, and no such obligations or Liabilities shall be assumed or retained by Buyer or its affiliates, including after the transactions contemplated hereby, Panhandle and the Panhandle Subsidiaries. (i) Notwithstanding the foregoing, any Affected Employee who is unable to report to work with Buyer as of the Closing Date due to disability (each, a "DISABLED EMPLOYEE"), shall continue to be eligible for any applicable long-term disability and life insurance coverage pursuant to Seller's plans until such Disabled Employee returns to active employment with Buyer, Panhandle or the Panhandle Subsidiaries; PROVIDED, HOWEVER, that in order to be eligible for such benefits, each such Disabled Employee, pending approval for long-term disability benefits or return to active employment, must continue to pay all applicable long-term disability and life insurance premiums due following the Closing Date for such coverage pursuant to Seller's long-term disability plan and life insurance plans. Buyer shall, or shall cause Panhandle or the Panhandle Subsidiaries to, (A) pay Disabled Employees who are on short-term disability as of the Closing Date the short-term disability benefits, if any, that apply under Buyer's plans, PROVIDED, HOWEVER, that such benefits need 45 not be provided to the extent that they would duplicate benefits paid under the Seller Plans, and (B) honor any continuing pay or salary obligations and return to work obligations that apply to any such Disabled Employees. Any Disabled Employees who are on short-term disability as of the Closing Date but who subsequently transition to long-term disability shall be eligible for, and covered by, Seller's long-term disability and life insurance coverage, subject to the provisions of this Section 5.5(b)(i). (c) As of the Closing Date, Buyer shall cause Panhandle and the Panhandle Subsidiaries to continue to employ all of the Affected Employees as of the Closing Date, other than those Affected Employees whose employment is covered by a Panhandle Eastern Pipe Line Company collective bargaining agreement as of the Closing Date, in Comparable Employment for a period of at least one (1) year from and after the Closing Date, or to pay severance if due in accordance with the terms of the Separation Allowance Plan for Employees of Panhandle and the Panhandle Subsidiaries or the Executive Separation Allowance Plan for Employees of Panhandle and the Panhandle Subsidiaries, as applicable. Notwithstanding the terms of the preceding sentence, Buyer shall cause Panhandle and the Panhandle Subsidiaries to employ all Affected Employees who are officers of Panhandle and the Panhandle Subsidiaries in Comparable Employment for a period of at least two (2) years from and after the Closing Date, or to pay severance if due in accordance with the terms of the Executive Separation Allowance Plan for Designated Officers of Panhandle and the Panhandle Subsidiaries or the Executive Separation Allowance Plan for Designated Senior Officers of Panhandle Eastern Pipe Line Company, as applicable. Employment of, and severance payments, if any, payable to, Affected Employees whose employment is covered by a Panhandle Eastern Pipe Line Company collective bargaining agreement as of the Closing Date shall be governed by the applicable collective bargaining agreement. (d) For no less than one-year following the Closing Date, Buyer shall, and shall cause Panhandle and the Panhandle Subsidiaries, to provide the Affected Employees with employee benefits that are substantially similar in the aggregate to those provided under the Seller Plans as such plans are to be in effect for 2003; provided, however, that Buyer shall not be obligated to replace any equity based plans in which Affected Employees could participate prior to Closing. With respect to those employee benefit plans of Panhandle and the Panhandle Subsidiaries or other Affiliates of Buyer ("BUYER PLANS") in which Affected Employees may participate on or after the Closing Date, Buyer shall, and shall cause Panhandle and the Panhandle Subsidiaries to, credit prior service of the Affected Employees with Panhandle and the Panhandle Subsidiaries for purposes of eligibility and vesting under Buyer Plans and for all purposes with respect to vacation, sick days, severance and post-employment benefits other than pensions ("PBOPS") under such Buyer Plans to the extent that such service was recognized under the analogous Employee Benefit Plans, provided however that such service need not be credited to the extent it would result in a duplication of benefits. Following the Closing Date, Buyer shall, or shall cause Panhandle and the Panhandle Subsidiaries to, honor the accrued vacation and sick days of the Affected Employees which remain unused as of the Closing Date to the extent such accruals are shown on the Closing Balance Sheet. Affected Employees shall also be given pro rata credit for any deductible or co-insurance 46 payment amounts payable in respect of the Buyer Plan year in which the Closing Date occurs, to the extent that, following the Closing Date, they participate in any Buyer Plan during such plan year for which deductibles or co-payments are required. Any preexisting condition restrictions and waiting period limitations which were deemed satisfied with respect to a particular person under any Employee Benefit Plan immediately prior to the Closing Date shall be deemed satisfied by Buyer and its Affiliates under Buyer Plans with respect to such person on and after the Closing Date. Promptly after the date hereof, Seller shall provide Buyer a list of Affected Employees and the status of such Affected Employees as of the Closing Date under Seller Plans providing for PBOPs, for the purpose of avoiding duplication of benefits. (e) Subject to the final sentence of this Section 5.5(e), Buyer agrees that, at the request of Seller, it shall cause Panhandle and the Panhandle Subsidiaries to make bonus payments to the bonus-eligible Affected Employees (as determined by Seller) for performance in the 2002 calendar year from funds made available by Seller for such purposes, which bonus payments shall be available as a tax deduction to Seller and Panhandle attributable to the pre-Closing Tax period. Buyer shall cause such payments to be made by Panhandle and the Panhandle Subsidiaries as soon as practicable after Buyer is informed by Seller of the bonus amounts to be paid to each bonus-eligible Affected Employee by name, as authorized by the Board of Directors of Parent. Seller and Buyer agree that the calculation of Net Working Capital Amount shall not reflect the bonus amounts accrued for the Affected Employees for accounting purposes (the "BONUS ACCRUAL") and that the Bonus Accrual shall be transferred to the books of Seller as of the Closing Date. To the extent not funded in advance, Seller shall promptly reimburse Buyer for the bonus amounts so paid (and the employer's share of any payroll taxes associated therewith), which reimbursement shall be treated as an adjustment to the Purchase Price. Seller and Buyer shall cooperate with respect to the development and distribution of any employee communications to be made to the Affected Employees after the Closing Date relating to 2002 bonuses. (f) Buyer, Panhandle and the Panhandle Subsidiaries shall be responsible for all Liabilities and obligations under the Worker Adjustment and Retraining Notification Act and similar foreign, state and local rules, statutes and ordinances resulting from the actions of Buyer, Panhandle or the Panhandle Subsidiaries after the Closing Date. Buyer agrees to hold Seller harmless in accordance with Article VIII for any breach of such responsibility and Buyer's indemnification of Seller in this regard specifically includes any Claim by the Affected Employees for back pay, front pay, benefits or compensatory or punitive damages, any Claim by any Governmental Authority for penalties regarding any issue of prior notification (or lack thereof) of any plant closing or mass layoff occurring after the Closing Date and Seller's costs, including reasonable attorney's fees, in defending any such Claims. (g) Notwithstanding the foregoing provisions of this Section 5.5, Buyer shall cause all obligations of Panhandle Eastern Pipe Line Company pursuant to existing collective bargaining agreements (which agreements are listed in Section 3.13 of the Seller Disclosure Letter) to be honored following the Closing. 47 (h) Parent or its Affiliates shall retain all assets that are accumulated through the Closing Date under Financial Accounting Standards Board Statement 106 (and deposited in various VEBA accounts and 401(h) accounts of Parent or its Affiliates). Further, Parent or its Affiliates shall retain the liability for PBOP for the benefit of former Panhandle Employees who are retirees of Panhandle and/or the Panhandle Subsidiaries as of the Closing Date, and Affected Employees who are eligible to retire and qualified for benefits under PBOP as of the Closing Date, and Parent or its Affiliates shall retain the responsibility for providing post-retirement benefits (other than pension) to such employees pursuant to the eligibility requirements of the Seller Plans. Seller shall provide a list of retirees and Affected Employees who are eligible to retire as of the Closing Date. Section 5.6 TAX COVENANTS (a) SECTION 338(h)(10) ELECTION. (i) Seller and Buyer shall jointly make an election under Section 338(h)(10) of the Code (and any comparable provision of applicable state or local income tax law) with respect to the purchase of the Shares by Buyer (and with respect to the Panhandle Subsidiaries for which such an election may be made) and shall cooperate with each other to take all actions necessary and appropriate (including filing such additional forms, returns, elections schedules and other documents as may be required) to effect and preserve a timely election, in accordance with the provisions of Treasury Regulation Section 1.338(h)(10)-1 (or any comparable provisions of state or local tax law) (the "ELECTION").

If, within thirty (30) days of the receipt of the draft Form 8023, Seller notifies Buyer that it disagrees with the draft Form 8023 and provides Buyer with its proposed Form 8023 and a written or oral explanation of the reasons for its adjustment, then Seller and Buyer shall attempt to resolve their disagreement within the twenty (20) days following Seller's notification of Buyer of such disagreement, otherwise, the draft Form 8023 shall become the final Form 8023 (the "FINAL FORM 8023"). If Seller and Buyer are unable to resolve their disagreement, the dispute shall be submitted to a mutually agreed upon nationally recognized independent accounting firm, whose expense shall be borne equally by Seller and Buyer, for resolution within twenty (20) days of such submission. The Form 8023 delivered by such accounting firm shall be the Final Form 8023. The Final Form 8023 shall be binding on Buyer, 48 Seller, and their respective Affiliates. Buyer and Seller shall take no position, and cause their respective Affiliates to take no position, inconsistent with the Final Form 8023. (iii) Buyer and Seller shall mutually prepare any forms or schedules similar to Form 8023 that are required for provisions of state or local law that are comparable to Treasury Regulation Section 1.338(h)(10)-1 in a manner similar to the above procedure. In the event that the Final Form 8023 (or similar forms or schedules required for provisions of state or local law) is disputed by any Taxing authority, the party receiving written notice of the dispute shall promptly notify the other party hereto concerning such dispute. (b) TAX RETURN FILINGS, REFUNDS, AND CREDITS. (i) Seller shall timely prepare and file (or cause such preparation and filing) with the appropriate Tax authorities all Tax Returns (including any Consolidated Income Tax Returns) with respect to Panhandle and the Panhandle Subsidiaries (and make all elections with respect to such Tax Returns) for Tax periods that end on or before the Closing Date (the "SELLER RETURNS"), and will pay (or cause to be paid) all Taxes due with respect to the Seller Returns. (ii) Buyer shall timely prepare and file (or cause such preparation and filing) with the appropriate Tax authorities all Tax Returns (the "STRADDLE PERIOD RETURNS") with respect to Panhandle and the Panhandle Subsidiaries (and make all elections with respect to such Tax Returns) for all Tax periods ending after the Closing Date that include the Closing Date (the "STRADDLE PERIOD"). All Straddle Period Returns shall be prepared in accordance with past practice to the extent consistent with applicable law and Panhandle's and the Panhandle Subsidiaries' operations. Buyer shall provide Seller with copies of any Straddle Period Returns at least forty-five (45) days prior to the due date thereof (giving effect to any extensions thereto), accompanied by a statement (the "STRADDLE STATEMENT") setting forth and calculating in reasonable detail the Pre-Closing Taxes as defined below. If Seller agrees with the Straddle Period Return and Straddle Statement, Seller shall pay to Buyer (or Buyer shall pay to Seller, if appropriate) an amount equal to the Pre-Closing Taxes as shown on the Straddle Statement not later than two (2) Business Days before the due date (including any extensions thereof) for payment of Taxes with respect to such Straddle Period Return. If, within fifteen (15) days of the receipt of the Straddle Period Return and Straddle Statement, Seller notifies Buyer that it disputes the manner of preparation of the Straddle Period Return or the amount calculated in the Straddle Statement, and provides Buyer its proposed form of Straddle Period Return, a statement setting forth and calculating in reasonable detail the Pre-Closing taxes, and a written or oral explanation of the reasons for its 49 adjustment, then Buyer and Seller shall attempt to resolve their disagreement within the five (5) days following Seller's notification or Buyer of such disagreement. If Buyer and Seller are unable to resolve their disagreement, the dispute shall be submitted to a mutually agreed upon nationally recognized independent accounting firm, whose expense shall be borne equally by Buyer and Seller, for resolution within twenty (20) days of such submission. The decision of such accounting firm with respect to such dispute shall be binding upon Buyer and Seller, and Seller shall pay to Buyer (or Buyer shall pay to Seller, if appropriate) an amount equal to the Pre-Closing Taxes as decided by such accounting firm not later than two (2) Business Days before the due date (including any extensions thereof) for payment of Taxes with respect to such Straddle Period Return. If for any reason the parties' dispute is not resolved as provided in this paragraph prior to the date that is two (2) Business Days before the due date (including any extensions thereof) for payment of Taxes with respect to such Straddle Period Return, Seller shall pay to Buyer (or Buyer shall pay to Seller, if appropriate) an amount equal to the amount of Pre-Closing Taxes not in dispute not later than two (2) Business Days before the due date (including any extensions thereof) for payment of Taxes with respect to such Straddle Period Return. (iii) From and after the Closing Date, Buyer and its Affiliates (including Panhandle and the Panhandle Subsidiaries) will not file any amended Tax Return, carryback claim, or other adjustment request with respect to Panhandle or the Panhandle Subsidiaries for any Tax period that includes or ends on or before the Closing Date unless Seller consents in writing; PROVIDED, HOWEVER, that Buyer and its affiliates may carryback for its own account (without paying any resulting refund or credit to Seller) any loss attributable to a tax period ending after the Closing Date to a tax period ending on or before the Closing Date provided that Buyer and its Affiliates shall indemnify and make Seller whole for any detriment or cost incurred (or to be incurred) by Seller as a result of such carryback (iv) For purposes of this Agreement, in the case of any Taxes of Panhandle or the Panhandle Subsidiaries that are payable with respect to any Straddle Period, the portion of any such Taxes that constitutes "PRE-CLOSING TAXES" shall be the excess of (A) (i) in the case of Taxes that are either (x) based upon or related to income or receipts or (y) imposed in connection with any sale, transfer or assignment or any deemed sale, transfer or assignment of property (real or personal, tangible or intangible) be deemed equal to the amount that would be payable if the Tax period ended at the close of business on the Closing Date (including without limitation all Taxes attributable to any Election) and (ii) in the case of Taxes (other than those described in clause (i)) imposed on a periodic basis with respect to the business or assets of Panhandle or the Panhandle Subsidiaries, be deemed to be the amount of such Taxes for the 50 entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding Tax period) multiplied by a fraction the numerator of which is the number of calendar days in the portion of the Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period over (B) any prepayment or advances of Taxes or any payments of estimated Taxes with respect to the Straddle Period. For purposes of clause (i) of the preceding sentence, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the total amount of such item allocated to the Straddle Period by a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period. Pre-Closing Taxes include any Taxes attributable to a Person that is treated as a partnership for federal income tax purposes as if such Person allocated Tax items to its partners in a manner consistent with this Section 5.6(b)(iv). In the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this Section 5.6(b)(iv) shall be computed by reference to the level of such items at the close of business on the Closing Date. The parties hereto will, to the extent permitted by Applicable Law, elect with the relevant Tax authority to treat a portion of any Straddle Period as a short taxable period ending as of the close of business on the Closing Date. For purposes of this Agreement, "POST-CLOSING TAXES" shall include any Taxes of Panhandle or the Panhandle Subsidiaries that are payable with respect to a Straddle Period, except for the portion of any such Taxes that constitutes Pre-Closing Taxes. For purposes of this Agreement, the Texas corporate franchise tax determined based on the income or capital of any entity for the year during which the Closing Date occurs shall be considered to be a Tax due with respect to the Straddle Period. (v) Seller and Buyer shall reasonably cooperate in preparing and filing all Tax Returns with respect to Panhandle or the Panhandle Subsidiaries, including maintaining and making available to each other all records reasonably necessary in connection with Taxes of Panhandle or the Panhandle Subsidiaries and in resolving all disputes and audits with respect to all Tax periods relating to Taxes of Panhandle or the Panhandle Subsidiaries. (vi) For a period of six (6) years after the Closing Date, Seller and its representatives shall have reasonable access to the books and records (including the right to make extracts thereof) of Panhandle or the Panhandle Subsidiaries to the extent that such books and records relate to Taxes and to the extent that such access may reasonably 51 be required by Seller in connection with matters relating to or affected by the operation of Panhandle or the Panhandle Subsidiaries prior to the Closing Date. Such access shall be afforded by Buyer upon receipt of reasonable advance notice and during normal business hours. If Buyer shall desire to dispose of any of such books and records prior to the expiration of such six-year period, Buyer shall, prior to such disposition, give Seller a reasonable opportunity, at Seller's expense, to segregate and remove such books and records as Seller may select. (vii) If a Tax Indemnified Party receives a refund or credit or other reimbursement with respect to Taxes for which it would be indemnified under this Agreement, the Tax Indemnified Party shall pay over such refund or credit or other reimbursement to the Tax Indemnifying Party. (viii) Buyer shall not, and shall cause Panhandle or the Panhandle Subsidiaries to not, make, amend or revoke any Tax election if such action would adversely affect any of Seller or its Affiliates with respect to any Tax period ending on or before the Closing Date or for the Pre-Closing Period or any Tax refund with respect thereto unless Buyer and its Affiliates indemnify and make Seller whole for any detriment or cost incurred (or to be incurred) by Seller as a result of such action. (ix) For purposes of this Agreement a "CONSOLIDATED INCOME TAX RETURN" is any income Tax Return filed with respect to any consolidated, combined, affiliated or unified group provided for under Section 1501 of the Code and the Treasury regulations under Section 1502 of the Code, or any comparable provisions of state or local law, other than any income Tax Return that includes only Panhandle or the Panhandle Subsidiaries. (c) INDEMNITY FOR TAXES. (i) Seller hereby agrees to indemnify Buyer and its affiliates against and hold them harmless from and against all liability for (i) all Taxes imposed on Panhandle or the Panhandle Subsidiaries with respect to Tax periods ending on or before the Closing Date, including without limitation all Taxes incurred by reason of any Election, (ii) Pre-Closing Taxes with respect to any Straddle Period, and (iii) all Taxes that are attributable to Seller or any member of an affiliated, consolidated, combined or unitary Tax group of which at least one of Panhandle or the Panhandle Subsidiaries (or any direct or indirect predecessor(s) of any of them) was a member at any time on or prior to the Closing Date and not after the Closing Date that is imposed under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign Tax law), (iv) any Taxes of Panhandle or any Panhandle Subsidiary incurred as a 52 transferee or a successor relating to any full or partial Tax period ending on or before the Closing Date, (v) Seller's portion of Transfer Taxes pursuant to Section 5.6(g), and (vi) any Damages arising out of, resulting from, or incurred in connection with any breach or inaccuracy of any representation or warranty set forth in Section 3.16; provided that the determination of whether such a breach or inaccuracy of Section 3.16(c)(d), or (e) occurred will be made without the Material Adverse Effect qualifications contained therein. (ii) Buyer hereby agrees to indemnify Seller and its Affiliates against and hold them harmless from all liability for (A) all Taxes of Panhandle or the Panhandle Subsidiaries with respect to all Tax periods beginning after the Closing Date, (B) Post-Closing Taxes with respect to any Straddle Period, and (C) Buyer's portion of Transfer Taxes pursuant to section 5.6(g). (iii) The obligation of Seller to indemnify and hold harmless Buyer, on the one hand, and the obligations of Buyer to indemnify and hold harmless Seller, on the other hand, pursuant to this Section 5.6, shall terminate upon the expiration of the applicable statutes of limitations with respect to the Tax Liabilities in question (giving effect to any waiver, mitigation or extension thereof) or if a Claim is brought with respect thereto, until such time as such Claim is resolved. (d) CERTAIN PAYMENTS. Buyer and Seller agree to treat (and cause their Affiliates to treat) any payment by Seller under Section 5.6(b)(ii) or Section 5.6(c) as an adjustment to the Purchase Price for all Tax purposes. (e) CONTESTS. (i) After the Closing Date, Seller and Buyer each shall notify the other party in writing within ten (10) days of the commencement of any Tax audit or administrative or judicial proceeding affecting the Taxes of any of Panhandle or the Panhandle Subsidiaries that, if determined adversely to the taxpayer (the "TAX INDEMNIFIED PARTY") or after the lapse of time would be grounds for indemnification under this Section 5.6 by the other party (the "TAX INDEMNIFYING PARTY" and a "TAX CLAIM"). Such notice shall contain factual information describing any asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any Tax authority in respect of any such asserted Tax liability. Failure to give such notification shall not affect the indemnification provided in this Section 5.6 except to the extent the Tax Indemnifying Party shall have been prejudiced as a result of such failure (except that the Tax Indemnifying Party shall not be liable for any expenses incurred during the period in which the Tax Indemnified Party failed to give such notice). Thereafter, the Tax Indemnified Party shall deliver to the Tax Indemnifying Party, as promptly as possible but in no 53 event later than ten (10) days after the Tax Indemnified Party's receipt thereof, copies of all relevant notices and documents (including court papers) received by the Tax Indemnified Party. (ii) In the case of an audit or administrative or judicial proceeding involving any asserted liability for Taxes relating to any Taxable years or periods ending on or before the Closing Date, Seller shall have the right, at its expense, to control the conduct of such audit or proceeding; provided, however, that if Seller does not timely take control of such audit or proceeding, Buyer may, at its expense, control the conduct of the audit or proceeding. In the case of an audit or administrative or judicial proceeding involving any asserted liability for Taxes relating to any Straddle Period, Buyer shall have the right, at its expense, to control the conduct of such audit or proceeding; PROVIDED, HOWEVER, that (A) Buyer shall keep Seller reasonably informed with respect to the status of such audit or proceeding and provide Seller with copies of all written correspondence with respect to such audit or proceeding in a timely manner and (B) if such audit or proceeding would be reasonably expected to result in a material increase in Tax liability of Panhandle or the Panhandle Subsidiaries for which Seller would be liable under this Section 5.6, Seller may participate in the conduct of such audit or proceeding at its own expense. (iii) In the case of an audit or administrative or judicial proceeding involving any asserted liability for Taxes relating to any Taxable years or periods beginning after the Closing Date, Buyer shall have the right, at its expense, to control the conduct of such audit or proceeding. (iv) Buyer and Seller shall reasonably cooperate in connection with any Tax Claim, and such cooperation shall include the provision to the Tax Indemnifying Party of records and information which are reasonably relevant to such Tax Claim and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. (f) SECTION 743 DETERMINATION. (i) Buyer and Seller shall reasonably cooperate with each other with respect to making any election under Section 754 of the Code for any Panhandle Subsidiary or any Related Company. Prior to making any adjustments pursuant to Section 743 of the Code as a result of the transactions contemplated by this Agreement Buyer shall prepare a schedule indicating such adjustments that Buyer proposes to make (the "743 SCHEDULE") and provide such schedule to Seller. If, within ten (10) days of the receipt of the 743 Schedule, Seller notifies Buyer that it disagrees with the 743 Schedule and provides Buyer with its proposed 743 54 Schedule and a written or oral explanation of the reasons for the adjustment, then Seller and Buyer shall attempt to resolve their disagreement within the twenty (20) days following Buyer's notification of Seller of such disagreement, otherwise, the 743 Schedule shall be deemed the final 743 Schedule (the "FINAL 743 SCHEDULE"). If Seller and Buyer are unable to resolve their disagreement, the dispute shall be submitted to a mutually agreed upon nationally recognized independent accounting firm, whose expense shall be borne equally by Seller and Buyer, for resolution within twenty (20) days of such submission. The 743 Schedule delivered by such accounting firm shall be the Final 743 Schedule. The Final 743 Schedule shall be binding on Buyer, Seller, and their respective Affiliates. Buyer and Seller shall take no position, and cause their respective Affiliates to take no position, inconsistent with the Final 743 Schedule. (ii) Buyer and Seller shall mutually prepare any forms or schedules necessary to give effect to the preceding paragraph. In the event that any Tax position taken in reliance upon the Final 743 Schedule is disputed by any Taxing authority, the party receiving written notice of the dispute shall promptly notify the other party hereto concerning such dispute. (g) TRANSFER AND SIMILAR TAXES. Notwithstanding any other provisions of this Agreement to the contrary, all sales, use, transfer, gains, stamp, duties, recording and similar Taxes (collectively, "TRANSFER TAXES") incurred in connection with the transactions contemplated by this Agreement shall be borne equally by Buyer and Seller, and Seller shall accurately file all necessary Tax Returns and other documentation with respect to Transfer Taxes and timely pay all such Transfer Taxes. If required by Applicable Law, Buyer will join in the execution of any such Return. Seller shall provide copies of any Tax Returns with respect to Transfer Taxes to Buyer no later than five (5) days after the due dates of such Tax Returns. (h) TERMINATION OF TAX SHARING AGREEMENTS. On or prior to the Closing Date, Seller shall cause all Tax sharing agreements between Seller or any of its Affiliates (as determined immediately after the Closing Date) on the one hand, and Panhandle or the Panhandle Subsidiaries on the other hand, to be terminated, and all obligations thereunder shall be settled, and no additional payments shall be made under any provisions thereof after the Closing Date." Section 5.7 INTERCOMPANY ACCOUNTS Except as set forth on Section 5.7 of the Seller Disclosure Letter or as contemplated by the Assumption Agreement, prior to the Closing Date, Seller shall, and shall cause its Affiliates (other than Panhandle and the Panhandle Subsidiaries) to, settle intercompany accounts payable (including any debt payable) to Panhandle or the Panhandle Subsidiaries and accounts receivable (including any debt receivable) from 55 Panhandle or the Panhandle Subsidiaries. Seller shall determine the method by which such intercompany accounts are eliminated including, but not limited to, by means of setoff, settlement, capital contribution or reduction in capital. Section 5.8 RELATED AGREEMENTS At the Closing or as otherwise provided herein, (i) Buyer and the Buyer Counterparties shall execute and deliver to Seller duly executed copies of the Related Agreements to which they are a party and (ii) Seller shall, and shall cause the Seller Counterparties to, execute and deliver to Buyer duly executed copies of the Related Agreements to which they are a party. Section 5.9 PRELIMINARY TRANSFER (a) In each case, prior to the Closing and in the form described in Section 5.9 of the Seller Disclosure Letter, Seller shall (i) cause the transfer of a newly formed holding company whose sole asset will be 100 percent of the ownership interests in CMS Gulf Coast Field Services, LLC ("CMSGCFS") to Panhandle or a Panhandle Subsidiary, and (ii) use its reasonable best efforts to cause the transfer of all of the ownership interests held by CMS Panhandle Holdings, LLC in each of Centennial Pipeline, L.L.C., a Delaware limited liability company ("CENTENNIAL"), and Guardian Pipeline, L.L.C., a Delaware limited liability company ("GUARDIAN"), and the contracts relating to such ownership interests to Seller or a Subsidiary of Seller (other than Panhandle or any of the Panhandle Subsidiaries). At the Closing, Seller shall update the Seller Disclosure Letter, where appropriate, to reflect the inclusion of such holding company, which owns the interests in CMSGCFS, as a Panhandle Subsidiary, and, assuming the transfer of the ownership interests in Centennial and/or Guardian and the contracts relating to such ownership interests have occurred prior to the Closing, the deletion of Centennial and/or Guardian as Related Companies. (b) If despite using its reasonable best efforts, Seller is unable to cause the transfer of the ownership interests in either Centennial or Guardian and the contracts relating to such ownership interests prior to the Closing, from and after the Closing Seller shall continue to use its reasonable best efforts to effect such transfer(s) as promptly as reasonably practical following the Closing. Until such time (after the Closing), as such ownership interests and contract rights have been transferred in accordance herewith, the ownership interests and contracts interests shall be held on behalf of Seller, such that all of the benefits and burdens appurtenant to such ownership interests and contracts shall remain with Seller and its Affiliates. All decisions relating to the operation and management of such ownership interests and contracts shall be made by Seller and implemented by Buyer in accordance with Seller's instructions, subject to applicable law. Seller shall indemnify Buyer, Panhandle and the Panhandle Subsidiaries in accordance with Article VIII for any Damages and Liabilities arising out of or relating 56 to such ownership interests and contracts relating to such ownership interests after the Closing and until the transfer(s) have been completed in accordance with this Section 5.9. Section 5.10 MAINTENANCE OF INSURANCE POLICIES (a) Seller and Buyer agree that Casualty Insurance claims relating to the businesses of Panhandle and the Panhandle Subsidiaries (including reported claims and including incurred but not reported claims) will remain with Panhandle and the Panhandle Subsidiaries immediately following the Closing. For purposes hereof, "CASUALTY INSURANCE CLAIMS" shall mean workers' compensation, auto liability, general liability and products liability claims and claims for damages caused to the facilities of Panhandle or the Panhandle Subsidiaries generally insured under all risk, real property, boiler and mechanical breakdown insurance coverage. The Casualty Insurance Claims are subject to the provisions of the Insurance Policies with insurance carriers and contractual arrangements with insurance adjusters maintained by Seller or its Affiliates prior to the Closing. With respect to the Casualty Insurance Claims, the following procedures shall apply: (i) Seller or its Affiliates shall continue to administer, adjust, settle and pay, on behalf of Panhandle and the Panhandle Subsidiaries, all Casualty Insurance Claims with dates of occurrence prior to the date of Closing; PROVIDED, that Seller will obtain the consent of Buyer prior to adjusting, settling or paying any Casualty Insurance Claim of an amount greater than $100,000 and PROVIDED, FURTHER, that Seller shall permit Buyer to join Seller in any settlement negotiations with claimants, insurers, or insurance adjusters; and (ii) Seller shall invoice Panhandle and the Panhandle Subsidiaries at the end of each month for Casualty Insurance Claims paid on behalf of Panhandle and the Panhandle Subsidiaries by Seller. Buyer shall cause Panhandle and the Panhandle Subsidiaries to pay the invoice within thirty (30) days of its date. In the event that Panhandle and the Panhandle Subsidiaries do not pay Seller within thirty (30) days of such invoice, interest at the rate of ten percent (10%) per annum shall accrue on the amount of such invoice. Casualty Insurance Claims to be paid by Seller hereunder shall include all costs necessary to settle claims including compensatory, medical, legal and other allocated expenses, net of insurance proceeds. In the event that any Casualty Insurance Claims exceeds a deductible or self-insured retention under the Insurance Policies, Seller shall be entitled to the benefit of any insurance proceeds that may be available to discharge any portion of such Casualty Insurance Claim. (b) Other than as set forth in Section 3.21 hereof, Seller makes no representation or warranty with respect to the applicability, validity or adequacy of any Insurance Policies, and Seller shall not be responsible to Buyer or any of its Affiliates for the failure of any insurer to pay under any such Insurance Policy. (c) Nothing in this Agreement is intended to provide or shall be construed as providing a benefit or release to any insurer or claims service organization of any obligation under any Insurance Policies. Seller and Buyer confirm that the sole intention of this Section 5.10 is to divide and allocate the benefits and obligations under the Insurance Policies between them as of the Closing Date and not to effect, enhance or 57 diminish the rights and obligations of any insurer or claims service organization thereunder. Nothing herein shall be construed as creating or permitting any insurer or claims service organization the right of subrogation against Seller or Buyer or any of their Affiliates in respect of payments made by one to the other under any Insurance Policy. (d) If Buyer requests a copy of an Insurance Policy relating to a pending or threatened Casualty Insurance Claim, Seller shall provide a copy of all relevant insurance policies which insure such Casualty Insurance Claims within five (5) Business Days, PROVIDED, that if Seller cannot provide such policy within five (5) days after exercising reasonable best efforts to locate such policy, Seller shall continue to exercise its reasonable best efforts to provide such policy to Buyer as soon as possible thereafter. Section 5.11 PRESERVATION OF RECORDS Buyer agrees that it shall, at its own expense, preserve and keep the records held by it relating to the respective businesses of Panhandle and the Panhandle Subsidiaries that could reasonably be required after the Closing by Seller for as long as may be required for such categories of records for the greater of the time periods required pursuant to the Access and Support Agreement and the time periods required pursuant to the applicable document retention program in effect on the Closing Date (a copy of which has been provided to Buyer). In addition, Buyer shall make such records available to Seller as may reasonably be required by Seller in connection with, among other things, any insurance claim, legal proceeding or governmental investigation relating to the respective businesses of Seller and its Affiliates, including Panhandle and the Panhandle Subsidiaries. Section 5.12 PUBLIC STATEMENTS On or prior to the Closing Date, neither party shall, nor shall permit its Affiliates to, issue or cause the publication of any press release or other announcement with respect to this Agreement or the transactions contemplated hereby without the consent of the other party hereto. Notwithstanding the foregoing, in the event any such press release or announcement is required by law, court process or stock exchange rule to be made by the party proposing to issue the same, such party shall use its reasonable best efforts to consult in good faith with the other party prior to the issuance of any such press release or announcement. Section 5.13 CERTAIN TRANSACTIONS Buyer, Southern Union and Funding shall not, and shall not permit any of their respective Subsidiaries to, and Highstar shall not, and shall not permit Southern Star 58 Central to, acquire or agree to acquire by merging or consolidating with, or by purchasing a substantial portion of the assets of or equity in, or by any other manner, any business or any corporation, partnership, association or other business organization or division thereof, or otherwise acquire or agree to acquire any assets if the entering into of a definitive agreement relating to, or the consummation of such acquisition, merger or consolidation would reasonably be expected to (i) impose any material delay in the obtaining of, or significantly increase the risk of not obtaining, any authorizations, consents, orders, declarations or approvals of any Governmental Authority necessary to consummate the transactions contemplated by this Agreement or the expiration or termination of any applicable waiting period, (ii) significantly increase the risk of any Governmental Authority entering an order prohibiting the consummation of the transactions contemplated by this Agreement, (iii) significantly increase the risk of not being able to remove any such order on appeal or otherwise or (iv) materially delay or prevent the consummation of the transactions contemplated by this Agreement.

Section 5.15 CHANGE OF CORPORATE NAME As soon as reasonably practicable following the Closing Date, but in no event later than ninety (90) days following the Closing Date (the "CORPORATE NAME CHANGE TRANSITION PERIOD"), Buyer shall cause each of Panhandle and the Panhandle Subsidiaries, as applicable, to change its corporate name to a name that does not include "CMS" and to make any necessary legal filings with the appropriate Governmental Authorities to effectuate such changes. Buyer shall hold harmless and indemnify Seller Indemnified Parties (as defined herein) against all costs, expenses and Damages to the extent incurred by Seller Indemnified Parties resulting from or arising in connection with Buyer's, Panhandle's or any Panhandle Subsidiary's use of the "CMS" name during the Corporate Name Change Transition Period.

(b) Panhandle's and the Panhandle Subsidiaries' right to use the Seller's Marks shall automatically cease as soon as reasonably practicable following the Closing Date, but in no event later than six (6) months following the Closing Date. Upon the termination of Panhandle's and the Panhandle Subsidiaries' right to use Seller's Marks, Panhandle and each Panhandle Subsidiary shall immediately cease all use of Seller's Marks and all materials bearing Seller's Marks (such materials to be returned to Seller or destroyed). (c) All rights and goodwill arising from the use of Seller's Marks and/or any similar names or marks (including logos) shall inure solely to Seller's benefit. Panhandle and the Panhandle Subsidiaries agree that neither Buyer, Panhandle nor any Panhandle Subsidiary shall use, directly or indirectly, the word "CMS" or any marks similar thereto, as part of Buyer's, Panhandle's or any Panhandle Subsidiary's own trade names, or in any other way that suggests that there is any relation or affiliation between Seller and Buyer, or Seller and Panhandle and the Panhandle Subsidiaries, other than that created by this Agreement, or as a trademark, service mark or trade name for any other business, product or service. Panhandle and Panhandle Subsidiaries shall have no interest in Seller's Marks except as expressly provided in this Agreement and shall not claim any other rights therein. Nothing in this Agreement or in the performance thereof, or that might otherwise be implied by law, shall operate to grant Panhandle and the Panhandle Subsidiaries any right, title, or interest in or to Seller's Marks other than as specified in the limited license grant in this Agreement. All rights not expressly granted in this Agreement or herein are reserved to Seller. (d) Panhandle and the Panhandle Subsidiaries agree to assign to Seller and do hereby assign to Seller all rights they may acquire, if any, by operation of law or otherwise in Seller's Marks, including all applications or registrations therefore, along with the goodwill associated therewith. Panhandle and the Panhandle Subsidiaries shall assist Seller in protecting and maintaining Seller's rights in Seller's Marks in connection with Panhandle's and the Panhandle Subsidiaries' licensed use hereunder, including preparation and execution of documents necessary or appropriate in the ordinary course to register Seller's Marks and/or record this Agreement. As between the parties, Seller shall have the sole right to, and in its sole discretion may, commence, prosecute or defend, and control any action concerning Seller's Marks. 60 (e) During the term of the Transitional License, Buyer, Panhandle and the Panhandle Subsidiaries shall not take, or agree or commit to take, any action that would or would be reasonably likely have an adverse impact on any of the Seller's Marks. (f) Neither Buyer, Panhandle, nor any Panhandle Subsidiary shall directly or indirectly, contest the validity of, by act or omission jeopardize, or take any action inconsistent with, Seller's rights in Seller's Marks (including attempting to register Seller's Marks or a mark incorporating either Seller's Marks or the word "CMS" or any mark similar thereto). Panhandle's and the Panhandle Subsidiaries' rights under the license granted herein are personal and may not be sublicensed, assigned or otherwise transferred. Section 5.17 REASONABLE BEST EFFORTS Upon the terms and subject to the conditions of this Agreement, each of the parties hereto will use all reasonable best efforts to take, or cause to be taken, all action, and to do, or cause to be done, all things necessary, proper or advisable consistent with applicable law to consummate and make effective in the most expeditious manner practicable the transactions contemplated hereby. Section 5.18 NO SHOPPING From and after the date hereof, none of Seller, Panhandle, the Panhandle Subsidiaries nor their officers, directors, employees, affiliates, stockholders, representatives, agents, nor anyone acting on behalf of them shall, directly or indirectly, encourage, solicit, engage in discussions or negotiations with, or provide any non-public information to, any Person (other than Buyer, the Sponsors or their respective representatives) concerning any merger, sale of assets, purchase or sale of Shares or similar transaction involving Panhandle or the Panhandle Subsidiaries (collectively, "PROHIBITED TRANSACTIONS") unless this Agreement is terminated pursuant to and in accordance with Article VII hereof; provided however, that nothing herein shall prohibit a transaction resulting in a change of control of any direct or indirect parent of Panhandle. Section 5.19 SPONSOR COVENANTS (a) The Sponsors, severally, shall cause Buyer to perform all of its obligations under this Agreement which are required to be performed on and prior to the Closing Date, including, without limitation, Buyer's requirement to consummate the transaction in accordance with and subject to the terms of Section 2.2 hereof and to pay 61 the Purchase Price in accordance with Article II. The Sponsors obligations shall be several, and not joint or joint and several; PROVIDED, HOWEVER, that if a Sponsor's action or inaction has resulted in a breach by such Sponsor, or in any way caused a breach by Buyer of any of its pre-Closing or Closing obligations under the Agreement, such Sponsor (and only such Sponsor) shall be solely liable for all Damages arising out of, resulting from or incurred in connection with such breach, and Seller shall have no claim against, and hereby releases, the non-breaching Sponsors, from any Liability with respect to such breach. Each of the Sponsors, Buyer and Seller acknowledges and agrees that no action shall be taken by Buyer hereunder without the consent of all Sponsors. Southern Union hereby irrevocably and unconditionally guaranties the performance by Funding of all of its obligations for the benefit of Seller under this Agreement. (b) Subject to the last sentence in Section 5.19(a) hereof, with respect to any payment obligations of Buyer under this Agreement, Southern Union's, Funding's and Highstar's obligations shall be several, and not joint or joint and several, and the funding of such payment obligations shall be borne 77.9% by Southern Union, 18.4% by Funding and 3.7% by Highstar. If a Sponsor does not fund its percentage of the Estimated Purchase Price at the intended Closing Date, notwithstanding that all of the condition's to Buyer's obligation to consummate the Closing have either been fulfilled or are capable of fulfillment on the Closing Date, each Sponsor who shall have funded or is prepared to fund shall be required to deposit their respective percentage of the Estimated Purchase Price into an escrow account designated by Seller pending the payment of each other Sponsor's share of the Estimated Purchase Price, at which time said funds shall be released to Seller. Seller and each Sponsor who shall have funded or been prepared to fund its percentage of the Estimated Purchase Price shall mutually agree in good faith upon an escrow agent to hold such funds, and together with the escrow agent, shall in good faith enter into an escrow agreement that will govern the holding of such funds. The escrow agreement shall provide that the escrow funds shall be released to each such Sponsor in the event that the Closing has not been consummated within 30 days of the date on which such funds were deposited. Section 5.20 CLOSING DELAY If the Closing has not occurred on or prior to March 31, 2003, a delay penalty (the "DELAY PENALTY") shall begin accruing on a daily basis on April 1, 2003 and shall continue until the earlier of the Closing Date or the termination of this Agreement in accordance with Article VII hereof, provided, as of such date, each of the conditions to Seller's obligation have been fulfilled or are reasonably capable of being fulfilled within a reasonable time. Southern Union shall pay the Delay Penalty to Seller in accordance with this Section 5.20, and the Delay Penalty shall be calculated as follows: (i) $100,000 per day in April, 2003; (ii) $200,000 per day in May 2003; and (iii) $300,000 per day on and after June 1, 2003; 62 Southern Union shall pay the Delay Penalty on the last day of each calendar month or, with respect to such month in which the Closing occurs or in which this Agreement is terminated in accordance with its terms, on the Closing Date or the termination date, as the case may be. For the avoidance of doubt, the Delay Penalty shall be retained by Seller whether or not the Closing occurs; provided, however, 25% of the Delay Penalty shall be credited towards Buyer's payment of the Estimated Purchase Price. Any Delay Penalty payable hereunder shall be paid exclusively by Southern Union and Seller shall have no claim against, and hereby releases, Buyer, Highstar and Funding and their respective affiliates (other than Southern Union) from any claim or Liability with respect to any such Delay Penalty. Section 5.21 RESTATED FINANCIALS Seller shall use its reasonable best efforts to deliver the Restated Financials to Buyer as soon as reasonably practicable after the date of this Agreement. Seller shall instruct Ernst & Young LLP to conduct an audit of the financial statements of Panhandle and the Panhandle Subsidiaries for the fiscal year ended December 31, 2002 as soon as reasonably practicable after Panhandle management completes such financial statements, Seller shall cooperate with such audit, and shall deliver to Buyer a copy of the audited financial statements of Panhandle and the Panhandle Subsidiaries for the fiscal year ended December 31, 2002 and Ernst & Young LLP's audit opinion thereon upon receipt of same. To the extent Buyer reasonably requires audited or reviewed financial statements with respect to Panhandle and the Panhandle Subsidiaries in order to comply with the reporting requirements of the Securities and Exchange Commission set forth in Regulations S-K and S-X, Seller will reasonably cooperate with Buyer (at Buyer's cost), including any reasonable request that Seller instruct Ernst & Young LLP to prepare and deliver to Buyer a comfort letter, customary in scope and substance for comfort letters delivered in similar circumstances. ARTICLE VI CONDITIONS Section 6.1 MUTUAL CONDITIONS TO THE CLOSING The respective obligations of each party to consummate the transactions contemplated by this Agreement shall be subject to the satisfaction or waiver of each of the following conditions at or prior to the Closing Date: (a) Any waiting period (and any extension thereof) applicable to the consummation of the transactions contemplated by this Agreement under the Hart- 63 Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR ACT"), shall have expired or have been terminated; (b) All waiting periods applicable to the transactions contemplated by this Agreement or any Related Agreement under any applicable other law shall have expired or been terminated, and all filings required by law to be made prior to Closing by Seller, a Sponsor or Buyer with, and all consents, approvals and authorizations required by law to be obtained prior to Closing by Seller, Sponsor or by Buyer from, any Governmental Authority under any law in order to consummate the transactions contemplated by this Agreement shall have been made or obtained (as the case may be), except where the failure for such waiting periods to expire or to be terminated, to make such filings, or to obtain any such authorizations, individually or in the aggregate, would not have a Material Adverse Effect; PROVIDED, HOWEVER, if any consent, approval or authorization from any Governmental Authority the absence of which would not have a Material Adverse Effect is not obtained prior to or at the Closing and, as a result, the transfer of one or more assets, rights or interests is prevented at the Closing, from and after the Closing, Seller, the affected Sponsor and Buyer shall continue to use their reasonable best efforts to obtain such requisite consent, approval or authorization. If the parties are unable to obtain the necessary approvals and, as a result, such assets, rights or interests may not be transferred to Buyer within 90 days after the Closing, the parties shall mutually agree on an acceptable adjustment to the purchase price to reflect the fair market value of such assets, rights or interests as of the Closing Date; and (c) No court of competent jurisdiction or other competent Governmental Authority shall have issued a statute, rule, regulation, order, decree or injunction or taken any other action that has the effect of restraining, enjoining, imposing a Burdensome Condition or otherwise prohibiting in any material respect the ownership by Buyer of the Shares or the ownership or operation by Buyer of a material portion of the business or assets of Panhandle and the Panhandle Subsidiaries, taken as a whole.

(c) by either Buyer or Seller upon written notice to the other party, if any of the mutual conditions to the Closing set forth in Section 6.1 shall have become incapable of fulfillment by June 30, 2003 or July 15, 2003, as the case may be, and shall not have been waived in writing by the other party; (d) by Buyer, so long as Buyer is not then in breach of its obligations under this Agreement, upon a breach of any covenant or agreement on the part of Seller set forth in this Agreement, or if any representation or warranty of Seller shall have been or become untrue, in each case such that the conditions set forth in Section 6.2 would not be satisfied; provided, however, that Buyer may not terminate this Agreement if such breach or untruth is capable of being cured by Seller by not later than June 30, 2003 or July 15, 2003, as the case may be, through the exercise of its reasonable best efforts, so long as Seller continues to exercise such reasonable best efforts (until not later than June 30, 2003 or July 15, 2003, as the case may be); (e) by Seller, so long as Seller is not then in breach of its obligations under this Agreement, upon a breach of any covenant or agreement on the part of Buyer or the Sponsors set forth in this Agreement, or if any representation or warranty of Buyer and the Sponsors shall have been or become untrue, in each case such that the conditions set forth in Section 6.3 would not be satisfied; PROVIDED, HOWEVER, that Seller may not terminate this Agreement if such breach or untruth is capable of being cured by Buyer and the Sponsors by not later than July 15, 2003, through the exercise of their reasonable best efforts, so long as Buyer and the Sponsors continue to exercise such reasonable best efforts (until not later than June 30, 2003 or July 15, 2003, as the case may be); and 67 (f) by either Seller or Buyer if any Governmental Authority shall have issued an order, decree or ruling or taken any other action, which permanently restrains, enjoins or otherwise prohibits the transactions contemplated by this Agreement and which order, decree, ruling or other action is not subject to appeal; unless failure to consummate closing because of such action by the Governmental Authority is due to the failure of the party seeking to terminate to have fulfilled its obligations under Section 5.3 and Section 5.4. Section 7.2 PROCEDURE AND EFFECT OF TERMINATION In the event of the termination of this Agreement pursuant to Section 7.1, (i) this Agreement, except for the provisions of Section 5.2(b), all of Article IX and this Section 7.2, shall become void and have no effect, without any Liability on the part of any party hereto or its directors, officers, stockholders or partners; PROVIDED, HOWEVER, that nothing in this Section 7.2 shall relieve any party for liability for any breach of this Agreement as set forth in the next succeeding sentence of this Section 7.2, and (ii) all filings, applications and other submissions made pursuant to this Agreement, to the extent practicable, shall be withdrawn from the agency or other Person to which they were made or appropriately amended to reflect the termination of the transactions contemplated hereby. Notwithstanding the foregoing, (a) nothing in this Section 7.2 shall relieve any party hereto of liability for Damages resulting from any breach of any of its obligations under this Agreement; PROVIDED, HOWEVER, that for purposes of this clause (a), Damages shall be deemed not to include Third Party Claims, and (b) if it shall be judicially determined that termination of this Agreement was caused by an intentional breach of this Agreement, then, in addition to other remedies at law or equity for breach of this Agreement, but subject to the limitation in clause (a) above, the party so found to have intentionally breached this Agreement shall indemnify and hold harmless the other party hereto for its respective out-of-pocket costs, including the fees and expenses of their counsel, accountants, financial advisors and other experts and advisors, as well as fees and expenses incident to the negotiation, preparation and execution of this Agreement and related documentation. ARTICLE VIII SURVIVAL; INDEMNIFICATION Section 8.1 SURVIVAL (a) The representations and warranties provided for in this Agreement shall survive the Closing and remain in full force and effect until the twelve-month (12) anniversary of this Agreement; PROVIDED HOWEVER, that the representations and warranties set forth in Section 3.2 (Authority Relative to this 68 Agreement), Section 3.3 (Shares), Section 3.19 (Brokerage and Finders' Fees), 4.2 (Authority Relative to this Agreement) and 4.7 (Brokerage and Finders' Fees) shall survive indefinitely, the representations and warranties set forth in Section 3.16 (Taxes) shall survive for a period equal to the applicable statute of limitations for each Tax and taxable year, and the representations and warranties set forth in Section 3.15 (Environmental; Health and Safety Matters) shall survive until the second (2nd) anniversary of the Closing Date. (b) No Claim for damages or other relief of any kind (including a Claim for indemnification under Section 8.2 hereof) arising against an Indemnified Party out of or relating to this Agreement or the transactions contemplated hereby, whether sounding in contract, tort, breach of warranty, securities law, other statutory cause of action, deceptive trade practice, strict liability, product liability or other cause of action or theory of liability (except, in all cases Claims alleging fraud, intentional misrepresentation or intentional misconduct), may be brought unless suit thereon is filed, or a written notice describing the nature of that Claim, the theory of liability, the nature of the relief sought and the material factual assertions upon which the Claim is based is given to the other party, before the termination of the Survival Period. (c) The survival period of each representation or warranty as provided in this Section 8.1 is referred to herein as the "SURVIVAL PERIOD." Notwithstanding the foregoing, any representation or warranty that would otherwise terminate shall survive with respect to Damages which respect to which suit thereon is filed or of which notice describing the nature of that Claim, the theory of liability, the nature of the relief sought and the material factual assertions upon which the Claim is based is given pursuant to this Agreement prior to the end of the Survival Period, until the matter is finally resolved and any related Damages are paid. Section 8.2 INDEMNIFICATION (a) Subject to the limitations set forth in this Article VIII, subsequent to the Closing, Seller shall indemnify, defend, save and hold harmless, Buyer, the Sponsors, Panhandle and the Panhandle Subsidiaries, their respective successors and permitted assigns, and their shareholders, members, partners (general and limited), officers, directors, managers, trustees, incorporators, employees, agents, attorneys, consultants and representatives, and each of their heirs, executors, successors and assigns (collectively, the "BUYER INDEMNIFIED PARTIES"), against and in respect of any and all Damages to the extent incurred by the Buyer Indemnified Party arising out of, resulting from or incurred in connection with: (i) any breach or inaccuracy of any representation or warranty of Seller contained in this Agreement; (ii) any breach by Seller of any covenant or agreement contained in this Agreement; and (iii) the matters set forth on Section 8.2(a)(iii) of the Seller Disclosure Letter. 69 (b) Subject to the limitations set forth in this Article VIII, subsequent to the Closing, Buyer shall indemnify, defend, save and hold harmless, Seller and its Affiliates, their respective successors and permitted assigns, and their shareholders, members, partners (general and limited), officers, directors, managers, trustees, incorporators, employees, agents, attorneys, consultants and representatives, and each of their heirs, executors, successors and assigns (collectively, the "SELLER INDEMNIFIED PARTIES") against and in respect of any and all Damages to the extent incurred by the Seller Indemnified Party arising out of, resulting from or incurred in connection with: (i) any breach or inaccuracy of any representation or warranty of Buyer or the Sponsors contained in this Agreement; and (ii) any breach by Buyer or the Sponsors of any covenant or agreement contained in this Agreement. (c) Any Person providing indemnification pursuant to the provisions of this Section 8.2 is referred to herein as an "INDEMNIFYING PARTY," and any Person entitled to be indemnified pursuant to the provisions of this Section 8.2 is referred to herein as an "INDEMNIFIED PARTY." (d) Seller's indemnification obligations contained in Section 8.2(a)(i) shall not apply to any Claim for Damages until the aggregate of all such Damages total $40,000,000 (the "THRESHOLD AMOUNT"), in which event Seller's indemnity obligation contained in Section 8.2(a)(i) shall apply to all Claims for Damages in excess of the Threshold Amount, subject to a maximum liability to all Indemnified Parties, in the aggregate, of $200,000,000 (the "CAP AMOUNT") for all Claims under Section 8.2(a)(i) in the aggregate. Damages relating to any single breach or series of related breaches of Seller's representations and warranties shall not constitute Damages, and therefore shall not be applied towards the Threshold Amount or be indemnifiable hereunder, unless such Damages relating to any single breach or series of related breaches exceed $1,000,000 (the "MINIMUM CLAIM AMOUNT"). (e) Buyer's indemnification obligations contained in Section 8.2(b)(i) shall not apply to any Claim for Damages until the aggregate of all such Damages equals the Threshold Amount, in which event Buyer's indemnification obligation contained in Section 8.2(b)(i) shall apply to all Claims for Damages in excess of the Threshold Amount, subject to a maximum liability to all Indemnified Parties, in the aggregate, of the Cap Amount for all Claims under Section 8.2(b)(i) in the aggregate. Damages relating to any single breach or series of related breaches of Buyer's and the Sponsors' representations and warranties shall not constitute Damages, and therefore shall not be applied towards the Threshold Amount or be indemnifiable hereunder, unless such Damages relating to any single breach or series of related breaches exceed the Minimum Claim Amount. 70 (f) The indemnification obligations of each party hereto under this Section 8.2 shall inure to the benefit of the Buyer Indemnified Parties and Seller Indemnified Parties, and such Buyer Indemnified Parties and Seller Indemnified Parties will be obligated to keep and perform the obligations imposed on an Indemnified Party by this Section 8.2, on the same terms as are applicable to such other party. (g) In all cases in which a Person is entitled to be indemnified in accordance with this Agreement, such Indemnified Party shall be under a duty to take all commercially reasonable measures to mitigate all losses. Without limiting the foregoing, each Indemnified Party shall use its reasonable best efforts to collect any amount available under insurance coverage, or from any other Person alleged to be responsible, for any Damages for which an indemnity claim is being made; provided, that the reasonable costs incurred by the Indemnified Party in taking such measures shall be included in the amount of any Claim. (h) An Indemnified Party shall not be entitled under this Agreement to multiple recovery for the same losses. If an Indemnified Party receives any amount under applicable insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount. (i) All amounts paid by Seller or Buyer, as the case may be, under this Article VIII shall be treated as adjustments to the Purchase Price for all Tax purposes. (j) Notwithstanding any other provision in the Agreement to the contrary, this Section 8.2 shall not apply to any Claim of indemnification with respect to Tax matters. Claims for indemnification with respect to Tax matters shall be governed by Section 5.6. (k) For purposes of this Article VIII only, the existence of a breach of a representation or warranty in this Agreement and the calculation of Damages arising out of a breach of any representation or warranty in this Agreement shall be determined without giving effect to any exception or qualification of such representation or warranty as to the materiality of the breach thereof or the Material Adverse Effect on any Person of such breach. Except as provided in Section 5.6 hereof, the provisions of this Article VIII shall constitute the sole and exclusive remedy of any Indemnified Party for Damages arising out of, resulting from or incurred in connection with any inaccuracy in any representation or the breach of any warranty made by Buyer or the Sponsors, on the one hand, or Seller, on the other hand, in this Agreement; PROVIDED, HOWEVER, that this exclusive remedy for Damages does not preclude a party from bringing an Action for specific performance or 71 other equitable remedy to require a party to perform its obligations under this Agreement or any Related Agreement; PROVIDED, FURTHER, that this exclusive remedy for Damages does not preclude a party from bringing an Action alleging fraud, intentional misrepresentation or intentional misconduct without reference to the provisions of this Article VIII. Section 8.3 CALCULATION OF DAMAGES The Damages suffered by any Party hereto shall be calculated after giving effect to the actual receipt of any available insurance proceeds paid directly to the Indemnified Party. In computing the amount of any insurance proceeds, such insurance proceeds shall be reduced by a reasonable estimate of the present value of future premium increases attributable to the payment of such Claim. Section 8.4 PROCEDURES FOR THIRD-PARTY CLAIMS (a) In the case of any Claim for indemnification arising from a Claim of a third party against an Indemnified Party arising under paragraph 8.2(a) or 8.2(b) as the case may be (a "THIRD-PARTY CLAIM"), an Indemnified Party shall give prompt written notice to the Indemnifying Party of any Claim or demand of which such Indemnified Party has knowledge, and as to which it may request indemnification hereunder, specifying (to the extent known) the amount of such Claim and any relevant facts and circumstances relating thereto; PROVIDED, HOWEVER, that any failure to give such prompt notice or to provide any such facts and circumstances will not waive any rights of the Indemnified Party, except to the extent that the rights of the Indemnifying Party are actually materially prejudiced thereby. The Indemnifying Party shall have the right (and, if it elects to exercise such right, to do so by written notice within thirty (30) days after receiving notice from the Indemnified Party) to defend and to direct the defense against any such Third-Party Claim, in its name or in the name of the Indemnified Party, as the case may be, at the expense of the Indemnifying Party, and with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party, unless (i) the Indemnifying Party shall not have taken any action to defend such Third-Party Claim within such thirty (30) day period, or (ii) the Indemnified Party shall have reasonably concluded that there is a conflict of interest between the Indemnified Party and the Indemnifying Party in the conduct of the defense of such Third-Party Claim. Notwithstanding anything in this Agreement to the contrary (other than the last sentence of this Section 8.4(a)), the Indemnified Party, at the expense of the Indemnifying Party (which shall include only reasonable out-of-pocket expenses actually incurred), shall cooperate with the Indemnifying Party and keep the Indemnifying Party fully informed in the defense of such Third-Party Claim. The Indemnified Party shall have the right to participate in the defense of any Third-Party Claim with counsel employed at its own expense; PROVIDED, HOWEVER, that in the case of any Third-Party Claim (A) described in clause (ii) above, or (B) as to which the Indemnifying Party shall not in fact have 72 employed counsel to assume the defense of such Third-Party Claim within such thirty-day (30-day) period, or (C) that involves assertion of criminal liability on the Indemnified Party, or (D) seeks to force the Indemnified Party to take (or prevent the Indemnified Party from taking) any action, then in each such case the Indemnified Party shall have the right, but not the obligation, to conduct and control the defense thereof for the account of, and at the risk of, the Indemnifying Party, and the reasonable fees and disbursements of such Indemnified Party's counsel shall be at the expense of the Indemnifying Party. Except as provided in the last sentence of Section 8.4(b), the Indemnifying Party shall have no indemnification obligations with respect to any Third-Party Claim which shall be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, delayed or conditioned. (b) The Indemnifying Party, if it has assumed the defense of any Third Party Claim as provided in this Agreement, shall not consent to a settlement of, or the entry of any judgment arising from, any such Third-Party Claim without the Indemnified Party's prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned) unless (i) such settlement or judgment relates solely to monetary damages, and (ii) prior to consenting to such settlement or such entry of judgment, the Indemnifying Party delivers to the Indemnified Party a writing (in form reasonably acceptable to the Indemnified Party) which unconditionally provides that, subject to the provisions of Section 8.2(d) or Section 8.2(e), as appropriate, relating to the Minimum Claim Amount, the Threshold Amount and the Cap Amount, the Damages represented thereby are the responsibility of the Indemnifying Party pursuant to the terms of this Agreement and that, subject to the provisions of the Threshold Amount, the Indemnifying Party shall pay all Damages associated therewith in accordance with the terms of this Agreement. The Indemnifying Party shall not, without the Indemnified Party's prior written consent, enter into any compromise or settlement that (x) commits the Indemnified Party to take, or to forbear to take, any action or (y) involves a reasonable likelihood of an imposition of criminal liability on the Indemnified Party, or (z) does not provide for a complete release by such third party of the Indemnified Party. With the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed, the Indemnified Party shall have the sole and exclusive right to settle any Third-Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third-Party Claim involves equitable or other nonmonetary relief against the Indemnified Party or involves a reasonable likelihood of an imposition of criminal liability on the Indemnified Party, and shall have the right to settle any Third-Party Claim involving money damages for which the Indemnifying Party has not assumed the defense pursuant to this Section 8.4. Section 8.5 PROCEDURES FOR INTER-PARTY CLAIMS In the event that an Indemnified Party determines that it has a Claim for Damages against an Indemnifying Party hereunder (other than as a result of a Third-Party Claim), the Indemnified Party shall give prompt written notice thereof to the Indemnifying Party, specifying the amount of such Claim and any relevant facts and circumstances relating 73 thereto, and such notice shall be promptly given even if the nature or extent of the Damages is not then known. The notification shall be subsequently supplemented within a reasonable time as additional information regarding the Claim or the nature or extent of Damages resulting therefrom becomes available to the Indemnified Party. Any failure to give such prompt notice or supplement thereto or to provide any such facts and circumstances will not waive any rights of the Indemnified Party, except to the extent that the rights of the Indemnifying Party are actually materially prejudiced thereby. The Indemnified Party and the Indemnifying Party shall negotiate in good faith for a thirty-day (30-day) period regarding the resolution of any disputed Claims for Damages.

CMS ENERGY REACHES AGREEMENT TO SELL CMS PANHANDLE COMPANIES FOR $1.8 BILLION TO
SOUTHERN UNION PANHANDLE

   Proceeds To Accelerate Debt Reduction and Bolster Liquidity Improvement Plan

   DEARBORN, Mich., Dec. 22 /PRNewswire-FirstCall/ -- CMS Energy (NYSE: CMS)
   announced today that it has reached a definitive agreement to sell CMS
   Panhandle Companies, its interstate natural gas pipeline business and
   accompanying subsidiaries, to Southern Union Panhandle for $1.828 billion.

   The agreement calls for Southern Union Panhandle -- a newly formed entity
   owned by Southern Union Company (NYSE: SUG) and AIG Highstar Capital, L.P. --
   to pay $662 million in cash and assume $1.166 billion in debt.

   CMS Energy intends to use the proceeds to accelerate debt reduction. The
   Company has reduced its debt by $860 million in 2002, including paying down
   $239 million in bank debt since July.

   The transaction has been approved by the Board of Directors of each company
   and is subject to customary closing conditions, action by the Federal Trade
   Commission under the Hart-Scott-Rodino Act, and by appropriate state
   regulators.

   "This sale is a significant step forward in our efforts to increase our
   financial flexibility. With this agreement, CMS Energy has sold or announced
   $3.6 billion in asset sales in 2002. Clearly, we are executing our asset
   sales plan, despite difficult market conditions," said Ken Whipple, CMS
   Energy chairman and chief executive officer. "We will continue to pursue
   strategies that support our back-to-basics approach and our focus on
   improving our balance sheet, reducing risk, and strengthening our liquidity."

   The Company announced August 7, 2002, that it was exploring the sale of CMS
   Panhandle Companies and other businesses in order to accelerate balance sheet
   improvement and enhance financial flexibility. Merrill Lynch & Co. acted as
   financial advisor to CMS in conjunction with a competitive sales process
   related to the divestiture of CMS Panhandle Companies.

   The CMS Panhandle Companies include CMS Panhandle Eastern Pipe Line Company,
   CMS Trunkline Gas Company, CMS Trunkline LNG Company, which operates an LNG
   terminal complex at Lake Charles, La., and CMS Sea Robin Pipeline Company.
   The present book value of these assets is approximately $2.4 billion. As
   previously announced on November 14, 2002, the Company expects to write off
   most of the goodwill associated with the CMS Panhandle Companies in the
   fourth quarter under the new accounting standard SFAS No. 142. After this
   adjustment, the book value of the assets will be materially closer to the
   $1.8 billion sale price.

   Under terms of the sales agreement, CMS Energy retains its ownership
   interests in the Centennial refined petroleum liquids pipeline, which
   stretches from Texas to Illinois, and the Guardian natural gas pipeline,
   which serves northern Illinois and southern Wisconsin and entered service on
   Dec. 7, 2002. CMS Energy owns a one-third interest in each and is exploring
   the sale of those interests.

   Southern Union Panhandle is owned by Southern Union Company and AIG Highstar
   Capital, L.P. Southern Union is an international energy distribution company
   serving nearly 1.5 million customers in Texas, Missouri, Pennsylvania, Rhode
   Island, Massachusetts and Mexico. AIG Highstar Capital, L.P. is a private
   equity fund sponsored by American International Group, Inc. to make
   structured equity investments in infrastructure related projects and
   operating companies.

   CMS Energy Corporation is an integrated energy company, which has as its
   primary business operations an electric and natural gas utility, natural gas
   pipeline systems and independent power generation.
