Following the Effective -8- 16 Time, CMS Energy and the Stockholders will determine the actual number of CMS Common Shares (and cash in lieu of fractional shares) deliverable upon surrender of all such Certificates (the "Actual Share Number") and the allocation thereof (on a pro rata basis) to each Certificate representing such issued and outstanding shares. Disputes regarding the Actual Share Number that are not resolved by the parties within five (5) business days after the later of (A) final determination of the purchase price (including the Balancing Payment) under the Amoco Stock Purchase Agreement and (B) the ninetieth (90th) day after the Effective Time shall be submitted to an arbitrator who is acceptable to both parties, and whose decision shall be final and binding with respect to the Actual Share Number. The fees and expenses of the arbitrator (if any) incurred in connection with the determination of the Actual Share Number shall be shared equally by CMS Energy and the Stockholders. If the Actual Share Number is greater than the Delivered Share Number, then CMS Energy shall deliver to the respective stockholders entitled thereto an aggregate number of whole CMS Common Shares equal to such excess (allocated as described above), together with the amount of all dividends and distributions which became payable to holders of record on or after the Effective Date in respect of such number of CMS Common Shares.

Until so surrendered, each outstanding certificate representing issued and outstanding shares of record of Walter Common Stock or Walter Preferred Stock immediately prior to the Effective Time shall not be transferable on the books of the Surviving Corporation or CMS Energy, but shall be deemed for all corporate purposes, subject to Section 2.5, to evidence the right to receive such cash and/or ownership of the number of whole CMS Common Shares, as the case may be, into which the shares of Walter Common Stock or Walter Preferred Stock, as the case may be, which immediately prior to the Effective Time were represented thereby shall have been converted pursuant to Section 2.1. At the close of business on the business day next preceding the Effective Date, the stock transfer books of Walter shall be closed and no transfer of Walter Common Stock or Walter Preferred Stock shall thereafter be made or consummated. SECTION 2.5. DIVIDENDS AND DISTRIBUTIONS. Any dividend or other distribution paid in respect of CMS Common Stock to holders of record on or after the Effective Date and -9- 17 otherwise payable to the holder of an outstanding certificate which, immediately prior to the Effective Time, represented issued and outstanding shares of Walter Common Stock or Walter Preferred Stock shall, until the surrender of such certificate and the issuance of a certificate or certificates for CMS Common Shares in respect thereof, be retained by CMS Energy pending such surrender, and no such dividend or other distribution payable in respect of CMS Common Stock shall be paid to the holder of such certificate representing Walter Common Stock or Walter Preferred Stock until such certificate shall have been so surrendered to CMS Energy and a certificate or certificates for CMS Common Shares shall have been so issued. Upon surrender of each such certificate and issuance in exchange therefor of CMS Common Shares, there shall be paid by CMS Energy to or at the direction of the holder of the certificate for such CMS Common Shares the amount of all dividends and distributions which became payable to holders of record on or after the Effective Date in respect of the number of whole CMS Common Shares represented by the certificate or certificates so issued. In no event shall the holder of any certificate which, immediately prior to the Effective Time, represented issued and outstanding shares of Walter Common Stock or Walter Preferred Stock be entitled to receive interest on any of the funds to be received in the Merger or on any such dividend or other distribution. SECTION 2.6. FRACTIONAL SHARES. No certificates for fractions of shares of CMS Common Stock and no scrip or other certificates evidencing fractional interests in such shares shall be issued pursuant to Section 2.1. If the conversion of a person's aggregate holdings of Walter Common Stock or Walter Preferred Stock at any time results in a fractional share of CMS Common Stock or interest therein, such person shall, in lieu thereof, be paid in cash in an amount equal to the value of such fractional share or interest based on the Average Price of CMS Common Stock. Any person otherwise entitled to a fractional share or interest shall not be entitled by reason thereof to any voting, dividend or other rights as a stockholder of CMS Energy. SECTION 2.7. CHANGES IN CMS COMMON STOCK. In the event that, during the period of ten (10) trading days which is used to determine the Average Price, or subsequent to such period but prior to the Effective Time, there has occurred the record date of any reclassification, stock split, stock dividend or similar change in respect of the CMS Common Stock, then appropriate adjustment shall be made in the number of shares of CMS Common Stock and/or kind of securities issued as CMS Common Shares in order to provide holders of Walter Common Stock or Walter Preferred Stock with the same number of shares of CMS Common Stock and/or securities that they would have received after such reclassification, stock split, stock dividend or similar change if the Effective Time had occurred immediately prior to the record date of such reclassification, stock split, stock dividend or similar change (and all references herein to -10- 18 the CMS Common Shares" shall refer to such adjusted number and/or kind of securities).

(ii) the Surviving Corporation has no plan or intention to issue additional shares of its stock that would result in CMS Energy's losing control of the Surviving Corporation within the meaning of section 368(c) of the Code; (iii) CMS Energy has no plan or intention to reacquire any of the CMS Common Stock issued in the Merger; (iv) CMS Energy has no plan or intention to liquidate the Surviving Corporation, to merge the Surviving Corporation with or into another corporation, to sell or otherwise dispose of the stock of the Surviving Corporation (except for a transfer of stock to a corporation controlled by CMS Energy within the -51- 59 meaning of section 368(a)(2)(C) of the Code and Treas. Reg. 1.368-2(j)(4)), or to cause the Surviving Corporation to sell or otherwise dispose of any of its assets or of any of the assets acquired from Sub except for dispositions made in the ordinary course of business (or a transfer of assets to a corporation controlled by CMS Energy within the meaning of section 368(a)(2)(C) of the Code and Treas Reg. 1.368-2(j)(4)); (v) Sub will have no liabilities assumed by the Surviving Corporation and will not transfer to the Surviving Corporation any assets subject to liabilities in the Merger; (vi) following the Merger, the Surviving Corporation will continue Walter's historic business or use a significant portion of Walter's historic business assets in a business; (vii) CMS Energy and Sub will pay their respective expenses, if any, incurred in connection with the Merger; (viii) there is no intercorporate indebtedness between CMS Energy and Walter or between Sub and Walter that will be settled at a discount following the Merger; (ix) CMS Energy is not an investment company as defined in section 368(a)(2)(F)(iii) and (iv) of the Code; and (x) the total cash consideration that will be paid in the Merger in lieu of issuing fractional shares of CMS Common Stock will not exceed one percent of the total fair market value of the CMS Common Stock (as of the Effective Time) to be issued in the Merger. SECTION 7.2. TAXES. (a) Liability for Taxes. (i) Except as shown as a liability or reserve on the Unaudited Balance Sheet, the Stockholders shall be liable for and indemnify CMS Energy, the Surviving Corporation and their subsidiaries (collectively, the "Tax Indemnitees") for all Taxes imposed on any Tax Indemnitee (or for which a Tax Indemnitee may otherwise be liable) arising from the assets or activities of Walter and its Subsidiaries for any taxable year or period of Walter or its Subsidiaries that ends on or before the Unaudited Balance Sheet Date and, with respect to any taxable year or period beginning before and ending after the Unaudited Balance Sheet Date, the portion of such taxable year ending on and including the Unaudited Balance Sheet Date (each such taxable year, period or portion thereof referred -52- 60 to herein as "Pre-June 30, 1994 Taxable Period"). Notwithstanding the preceding sentence, in the case of an adjustment which increases an item of income or gain, or decreases an item of loss, deduction or credit, of Walter or any of its Subsidiaries for any Pre-June 30, 1994 Taxable Period and which will (under the law in effect at the time of such adjustment) result in a corresponding decrease in an item of income or gain, or an increase in an item of loss, deduction or credit, of Walter, any of its Subsidiaries, or the Surviving Corporation for one or more taxable years or periods following the year or period to which the adjustment relates (a "Timing Adjustment"), the Shareholders shall not be required to pay to the Tax Indemnitees any increase in the tax liability of Walter and its Subsidiaries attributable to such Timing Adjustment, but shall be required to pay to the Tax Indemnitees the amount of any interest and penalties payable as a result of such Timing Adjustment, provided that if the representations set forth in Sections 3.8(a)(xx) through 3.8(a)(xxiii) are breached other than as a result of Timing Adjustments (including as a result of an adjustment (other than a Timing Adjustment) to the taxable income of Walter or its Subsidiaries for a taxable year or period that ends on or before the Unaudited Balance Sheet Date which is used to reduce the net operating loss carryforwards of Walter and its Subsidiaries described in such Sections), the Stockholders shall pay to the Tax Indemnitees an amount equal to the sum of (y) 20% of the amount by which the net operating loss carryovers set forth in Schedule 3.8(b) or Schedule 3.8(c) from any taxable period exceed the amount of net operating loss carryovers as finally determined from such taxable period; provided, that the aggregate amount payable by the Stockholders pursuant to this clause (y) by reason of all such breaches shall not exceed $1,000,000, plus (z) the amount of any interest and penalties payable as a result of the reduction in such net operating loss carryover. Notwithstanding the preceding sentence, the Stockholders shall not be required to indemnify the Tax Indemnitees as a result of the breach of the representations described in Sections 3.8(a)(xx) through 3.8(a)(xxiii) unless the unavailability of any of the carryovers described therein are challenged in the audit of the Tax Returns filed by CMS Energy and its Affiliates for their taxable years ending on or before December 31, 1999. (ii) The Tax Indemnitees shall be liable for and indemnify the Stockholders for the Taxes of Walter and its Subsidiaries for any taxable year or period that begins after the Unaudited Balance Sheet Date and, with respect to any taxable year or period beginning before and ending after the Unaudited Balance Sheet Date, the portion of such taxable year or period beginning after the Unaudited Balance Sheet Date. (iii) For purposes of paragraphs (a)(i) and (a)(ii), whenever it is necessary to determine the liability for Taxes of Walter and its Subsidiaries for a portion of a taxable year or -53- 61 period that begins before and ends after the Unaudited Balance Sheet Date, the determination of the Taxes of Walter and its Subsidiaries for the portion of the year or period ending on, and the portion of the year or period beginning after, the Unaudited Balance Sheet Date shall be determined by assuming that Walter and its Subsidiaries had a taxable year or period which ended at the close of the Unaudited Balance Sheet Date, except that exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, shall be apportioned on a daily basis. (iv) The Stockholders shall be liable for all transfer, sales or similar Taxes arising from the Merger and the other transactions contemplated by this Agreement. (v) Within twenty (20) days after the execution of this Agreement, the Stockholders shall deliver or cause to be delivered to CMS Energy or its designee true and complete copies of: (A) all income Tax Returns of Walter and its Subsidiaries requested by CMS Energy or its Subsidiaries; (B) any other Tax Returns requested by CMS Energy or its Subsidiaries, as may be relevant to Walter and its Subsidiaries and their assets and operations; and (C) any workpapers or other supporting data requested by CMS Energy or its subsidiaries relating to "income taxes payable" or similar line item reflected in the Unaudited Statement of Income and Unaudited Balance Sheet relating to Tax Returns made available pursuant to (A) or (B), or relating to Tax Returns referred to in (A) or (B) not yet filed, to the extent copies of such Tax Returns, work papers or other data are in existence and in the possession of Walter at the time of such request. (b) Tax Returns. Walter shall file when due (after taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to Walter and its Subsidiaries on or before the Effective Date and shall remit or cause to be remitted any Taxes shown to be due on such Tax Returns, and the Surviving Corporation shall file when due (after taking into account all extensions properly obtained) all Tax Returns that are required to be filed by Walter and its Subsidiaries after the Effective Date and shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. All Tax Returns which Walter is required to file in accordance with this paragraph (b) shall be prepared and filed in a manner consistent with past practice and, on such Tax Returns, no position shall be taken or method adopted that is inconsistent with positions taken or methods used in preparing and filing similar Tax Returns in prior periods except for changes required by law or changes in facts. (c) Contest Provisions. CMS Energy or one of its subsidiaries shall notify the Stockholders in writing upon receipt by any Tax Indemnitee of notice of any pending or -54- 62 threatened federal, state, local or foreign Tax audit or assessment which may materially affect the Tax liabilities of Walter or its Subsidiaries for which the Stockholders would be required to indemnify the Tax Indemnitees pursuant to Section 10.1 or this Section 7.2, provided, that failure to comply with this provision shall not affect the Tax Indemnitees' right to indemnification hereunder except to the extent that such omission results in a failure of actual knowledge of the Stockholders and the Stockholders are damaged as a result of such failure of actual knowledge. The Stockholders shall have the sole right to represent the interests of Walter and its Subsidiaries in any Tax audit or administrative or court proceeding relating to taxable periods ending on or before the Unaudited Balance Sheet Date, and to employ counsel of their choice at their expense, provided that the Tax Indemnitees (and their tax counsel) may, at their own expense, be present at and participate in any such audit or proceeding. Notwithstanding the foregoing, the Stockholders shall not be entitled to settle, either administratively or after the commencement of litigation, any claim that would constitute a Timing Adjustment or any claim for Taxes which would adversely affect the liability for Taxes of the Tax Indemnitees for any period after the Unaudited Balance Sheet Date to any extent (including, but not limited to, the imposition of income Tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization, depreciation or depletion deductions, or the reduction of loss or credit carryforwards) without the prior written consent of the Tax Indemnitees. Such consent shall not be necessary to the extent that the Stockholders have indemnified the Tax Indemnitees in a manner acceptable to the Tax Indemnitees against the effects of any such settlement. (d) Assistance and Cooperation. After the Effective Date, each of the Stockholders and the Tax Indemnitees shall: (i) agree to timely sign and deliver such certificates or forms as may be necessary or appropriate to establish an exemption from (or otherwise reduce), or make a report with respect to, Taxes described in paragraph (a)(iv) of this Section 7.2; (ii) assist (and cause their respective affiliates to assist) the other parties in preparing any Tax Returns which such other parties are responsible for preparing and filing in accordance with paragraph (b) of this Section 7.2; (iii) cooperate fully in preparing for any audits of, or disputes with taxing authorities regarding, any Tax Returns of Walter and its Subsidiaries; -55- 63 (iv) make available to the other parties and to any taxing authority as reasonably requested all information, records, and documents relating to Taxes of Walter and its Subsidiaries; (v) provide timely notice to the other parties in writing of any pending or threatened Tax audits or assessments of Walter and its Subsidiaries for taxable periods for which the other may have a liability under this Section 7.2; and (vi) furnish the other with copies of all correspondence received from any taxing authority in connection with any Tax audit or information request with respect to any such taxable period. (f) Adjustment to Purchase Price. Any payment by the Stockholders under this Section 7.2 shall be considered an adjustment to the consideration paid in connection with the Merger. (g) Survival of Obligations. Notwithstanding Article X, the obligations of the Stockholders and the Tax Indemnitees set forth in this Section 7.2 shall be unconditional and absolute and shall remain in effect without limitation as to time and the Stockholders' obligations under this Section 7.2 shall not be limited as set forth in Section 10.1. (h) No Duplication of Indemnities. To the extent that the provisions of this Section 7.2 conflict with the provisions of Article X, the provisions of this Section 7.2 shall control and no double payment shall be made with respect to any breach or alleged breach of any representation or warranty contained in Section 3.8.

ARTICLE X INDEMNIFICATION; SURVIVAL SECTION 10.1. INDEMNIFICATION BY THE STOCKHOLDERS. From and after the Effective Time, each of the Stockholders shall indemnify and hold harmless CMS Energy, the Surviving Corporation and their subsidiaries, affiliates and successors from and -63- 71 against any and all (a) liabilities, losses, costs or damages ("Loss") and (b) reasonable attorneys', consultants' and accountants' fees and expenses, court costs and all other reasonable out-of-pocket expenses ("Expense") incurred by CMS Energy, the Surviving Corporation and their subsidiaries, affiliates and successors in connection with or arising from (i) any breach or failure to perform by any Stockholder of any of its respective agreements, covenants or obligations in this Agreement or any agreement entered into in connection with the transactions contemplated hereby, in each case to be performed or complied with after the Effective Time, as the case may be, (ii) any breach of any warranty or the inaccuracy of any representation of Walter or any Stockholder contained in this Agreement, as updated in accordance with Section 10.7 hereof, or in any certificate delivered by or on behalf of Walter or any Stockholder pursuant hereto, (iii) any reduction in the Discounted Present Value (as hereinafter defined) of all future net cashflows (including for periods after one year after the Effective Date) to Walter's direct or indirect interest from the Equatorial Guinea Production Sharing Contract ("PSC") arising solely from any unilateral change made to the PSC by the Government of the Republic of Equatorial Guinea or any agency or instrumentality thereof effected at any time during the period beginning June 1, 1994 and ending one year after Effective Date; and (iv) the litigation referred to in Schedule 3.17, including, but not limited to the Waldroup and the Aker/Addax litigation; provided, however, that the Stockholders shall be required to indemnify and hold harmless under this Section 10.1 with respect to the breach or inaccuracy of any representations or warranties only to the extent that the aggregate amount of Loss and Expense referred to above in this Section 10.1 relating thereto exceeds U.S. $300,000, except for any Loss or Expense incurred in connection with or arising from any breach or inaccuracy of the representations and warranties contained in Section 3.3 and 3.4, as to which no such limitation shall apply; and provided further, that each Stockholder's obligation to indemnify and hold harmless pursuant to this Section 10.1 shall be limited to the payment by such Stockholder (excluding any amounts reimbursed to such Stockholder) of cash in the aggregate in an amount equal to the product obtained by multiplying the Average Price by the number of such Stockholder's shares of Walter Common Stock immediately prior to the Effective Time; and provided further, that no Stockholder shall have any obligation to indemnify and hold harmless any indemnified party with respect to any Loss or Expense arising from any breach of a warranty, or inaccuracy of a representation, of any other Stockholder contained in Section 3.3(b) or 3.4(b) or 3.34 or of any Preferred Stockholder contained in Section 3.3(b) or 3.4(b) or of any Warrantholder contained in Section 3.3(b) or 3.4(b). Discounted Present Value of future net cashflows shall mean the future revenues from sales of condensate production under the PSC attributable to the interest of Walter and its Subsidiaries therein after deducting all associated operating costs, royalties, other burdens on production, capital expenditures, -64- 72 other applicable costs and all foreign and U.S. taxes, discounted at a 25% annual rate. Change in Discounted Present Value shall be calculated by comparing the Discounted Present Value under the Modified Economic Model to the Discounted Present Value under the Original Economic Model (as hereinafter defined). Modified Economic Model shall mean the economic model of the PSC used to compute discounted present value of the Alba field under the PSC as made available to CMS Energy by Walter in connection with the negotiation of the transactions contemplated by this Agreement, a copy of which is included in Schedule 3.33(a) attached hereto ("Original Economic Model"), modified to reflect any unilateral changes to the PSC made by the Republic of Equatorial Guinea, all other factors remaining the same. Stockholders reserve the right to assume, at their sole cost and expense, the defense against any attempted unilateral change to the PSC that would give rise to an indemnity right hereunder; provided, however, that any such defense shall be conducted in accordance with all applicable laws and agreements; and provided, further, that counsel for the Stockholders, who shall conduct the defense of such matter, shall be reasonably satisfactory to CMS Energy; and provided, further, that CMS Energy shall have the right to have separate counsel reasonably acceptable to the Stockholders act on behalf of CMS Energy, at its expense. If the Stockholders assume the defense of any such matter, the Stockholders shall not consent to entry of any judgment, or enter into any settlement, without the written consent of CMS Energy. If the Stockholders do not assume the defense of any such matter, in accordance with the terms hereof, CMS Energy may defend against such claim or litigation in such manner as it may deem appropriate, including, without limitation, settling such matter, on such terms as CMS Energy may deem appropriate, and the Stockholders will promptly indemnify CMS Energy, if required, in accordance with the provisions of this Section 10.1. Any change to the PSC as a result of bilateral negotiations or any act or omission of the Surviving Corporation in violation of the PSC or applicable law, rule or order of general applicability after the Effective Time is specifically excluded from the indemnity contained in clause (iii) above. SECTION 10.2. INDEMNIFICATION BY CMS ENERGY AND THE SURVIVING CORPORATION. From and after the Effective Time, CMS Energy and the Surviving Corporation shall jointly and severally indemnify and hold harmless the Stockholders and their subsidiaries, affiliates and successors from and against any and all Loss and Expense incurred by the Stockholders and their subsidiaries, affiliates and successors in connection with or arising from (a) any breach or failure to perform by CMS Energy or the Surviving Corporation of any of their respective agreements, covenants or obligations in this Agreement or any agreement entered into in connection with the transactions contemplated hereby or thereby, in each case to be performed or complied with after the Effective Time, and (b) any breach of any warranty or the inaccuracy of any representation of CMS Energy or -65- 73 Sub contained in this Agreement or in any certificate delivered by or on behalf of CMS Energy or Sub pursuant hereto or thereto; provided, however, that CMS Energy and the Surviving Corporation shall be required to indemnify and hold harmless under this Section 10.2 with respect to the breach or inaccuracy of any representations or warranties only to the extent that the aggregate amount of Loss and Expense referred to above in this Section 10.2 relating thereto exceeds U.S. $300,000; and provided, further, that the obligation of CMS Energy and the Surviving Corporation to indemnify and hold harmless pursuant to this Section 10.2 shall be limited to the aggregate payment by CMS Energy and/or the Surviving Corporation of an amount equal to U.S. $10,000,000. In addition, from and after the Effective Time, if any Stockholder is named as a defendant in any lawsuit by a third party for a claim against the Surviving Corporation or any affiliate thereof, for which neither Walter nor any Stockholder has any liability, CMS Energy and the Surviving Corporation shall indemnify and hold harmless each such named Stockholder, to the extent permitted by applicable law, from all Loss and Expense relating to such matter without regard to the $300,000 required minimum amount set forth in the preceding sentence. SECTION 10.3. NOTICE OF CLAIMS. If CMS Energy (with respect to Section 10.1) or the Stockholders (with respect to Section 10.2) believe that any of the persons entitled to indemnification under this Article X has suffered or incurred any Loss or incurred any Expense, whether or not the applicable dollar limitation specified by Section 10.1 or 10.2 has been exceeded, CMS Energy or such Stockholders, as the case may be, shall so notify the other promptly in writing describing such Loss or Expense, the amount thereof, if known, and the method of computation of such Loss or Expense, all with reasonable particularity and containing a reference to the provisions of this Agreement or any certificate delivered pursuant hereto in respect of which such Loss or Expense shall have occurred; provided, however, that the omission by such indemnified party to give notice as provided herein shall not relieve the indemnifying party of its indemnification obligation under this Article X except to the extent that such omission results in a failure of actual notice to the indemnifying party and such indemnifying party is materially damaged as a result of such failure to give notice. If any action at law or suit in equity is instituted by or against a third party with respect to which any of the persons entitled to indemnification under this Article X intends to claim any liability or expense as Loss or Expense under this Article X, any such person shall promptly notify the indemnifying party of such action or suit as specified in this Section 10.3 and Section 10.4. Any party entitled to indemnification hereunder shall use reasonable efforts to minimize any Loss or Expense for which indemnification is sought hereunder. -66- 74 SECTION 10.4. THIRD PARTY CLAIMS. In the event of any claim for indemnification hereunder resulting from or in connection with any claim or legal proceeding by a third party, the indemnified persons shall give such notice thereof to the indemnifying party not later than twenty (20) days prior to the time any response to the asserted claim is required, if possible, and in any event within fifteen (15) days following the date such indemnified person has actual knowledge thereof; provided, however, that the omission by such indemnified party to give notice as provided herein shall not relieve the indemnifying party of its indemnification obligation under this Article X except to the extent that such omission results in a failure of actual notice to the indemnifying party and such indemnifying party is materially damaged as a result of such failure to give notice. In the event of any such claim for indemnification resulting from or in connection with a claim or legal proceeding by a third party, the indemnifying party may, at its sole cost and expense, assume the defense thereof; provided, however, that counsel for the indemnifying party, who shall conduct the defense of such claim or legal proceeding, shall be reasonably satisfactory to the indemnified party; and provided, further, that if the defendants in any such actions include both the indemnified persons and the indemnifying party and the indemnified persons shall have reasonably concluded that there may be legal defenses or rights available to them which have not been waived and are in actual or potential conflict with those available to the indemnifying party, the indemnified persons shall have the right to select one law firm reasonably acceptable to the indemnifying party to act as separate counsel, on behalf of such indemnified persons, at the expense of the indemnifying party. Subject to the second proviso of the immediately preceding sentence, if an indemnifying party assumes the defense of any such claim or legal proceeding, such indemnifying party shall not consent to entry of any judgment, or enter into any settlement, that (a) is not subject to full indemnification hereunder (except for the deductible referred to in the first proviso to the first sentence of each of Section 10.1 and Section 10.2), (b) provides for injunctive or other non-monetary relief affecting the indemnified persons or (c) does not include as an unconditional term thereof the giving by each claimant or plaintiff to such indemnified persons of a release from all liability with respect to such claim or legal proceeding, without the prior written consent of the indemnified persons (which consent, in the case of clauses (b) and (c), shall not be unreasonably withheld); provided, however, that subject to the second proviso of the immediately preceding sentence, the indemnified persons may, at their own expense, participate in any such proceeding with the counsel of their choice without any right of control thereof. So long as the indemnifying party is in good faith defending such claim or proceeding, the indemnified persons shall not compromise or settle such claim or proceeding without the prior written consent of the indemnifying party, which consent shall not be unreasonably withheld. If the indemnifying -67- 75 party does not assume the defense of any such claim or litigation in accordance with the terms hereof, the indemnified persons may defend against such claim or litigation in such manner as they may deem appropriate, including, without limitation, settling such claim or litigation (after giving prior written notice of the same to the indemnifying party and obtaining the prior written consent of the indemnifying party, which consent shall not be unreasonably withheld) on such terms as the indemnified persons may deem appropriate, and the indemnifying party will promptly indemnify the indemnified persons in accordance with the provisions of this Section 10.4. SECTION 10.5. EXCLUSIVE REMEDY. In the event the Merger is consummated, any claim against either the Stockholders or CMS Energy or the Surviving Corporation for any breach of this Agreement or in connection with any of the transactions contemplated hereby (other than a claim for breach of Section 7.2 and other than claims by or against the Preferred Stockholders) shall, to the extent permitted by law, be made solely pursuant to this Article X. SECTION 10.6. SURVIVAL OF OBLIGATIONS. All representations, warranties, covenants and obligations contained in this Agreement shall survive the consummation of the transactions contemplated by this Agreement; provided, however, that the representations and warranties in Articles III and IV shall terminate on the third anniversary of the Effective Date except for the representations and warranties contained in Sections 3.3 and 3.4, which shall survive without termination, the representations and warranties contained in Section 3.9, which shall terminate on the first anniversary of the Effective Date, the representations contained in Sections 3.8, 3.22 and 7.1(c), which shall survive until expiration of the applicable statute of limitations, and any representations relating to ACEC, which shall terminate on the second anniversary of the Effective Date; and provided, further, that if any claim under this Article X for Loss or Expense in respect of any representations and warranties is asserted in writing prior to the expiration of the applicable period set forth above, the obligations of the indemnifying party with respect to such claim shall not be affected by the expiration of such period. SECTION 10.7. UPDATE OF THE REPRESENTATIONS AND WARRANTIES. (a) Not later than ten days prior to the Effective Date, Walter, any Stockholder, any Preferred Stockholder and any Warrantholder may deliver a written notice to CMS Energy setting forth any and all facts, conditions, occurrences, changes and other matters, in each case, occurring after the date hereof, that has caused or may cause the representations and warranties of the Stockholders, the Preferred Stockholders and/or the Warrantholders contained herein (including the Schedules hereto) not to be true and correct in all respects (in the case of any representation or warranty containing any materiality -68- 76 qualification) or in all material respects (in the case of any representation and warranty without any materiality qualification). In the event that any of such facts, conditions, occurrences, changes and other matters shall have caused or will cause, on or prior to the Effective Date, any such representation or warranty not to be true and correct in all respects (in the case of any representation or warranty containing any materiality qualification) or in all material respects (in the case of any representation and warranty without any materiality qualification) on the Effective Date with the same effect as though made on the Effective Date, CMS Energy may elect to terminate this Agreement pursuant to Section 11.1(d) based on such facts, conditions, occurrences, changes or other matters. If CMS Energy shall nevertheless proceed to consummate the Merger, such facts, conditions, occurrences, changes and other matters so disclosed as to each such representation or warranty of the Stockholders, the Preferred Stockholders and/or the Warrantholders contained herein (including the Schedules) shall be deemed to constitute an exception to such representation or warranty reflecting the facts, conditions, occurrences, changes and other matters so disclosed with the same effect as if such exception had been made in such representation or warranty as of the date hereof in this Agreement to the extent, but only to the extent, of such disclosure. (b) Not later than ten days prior to the Effective Date, CMS Energy may deliver a written notice to Walter, the Stockholders, the Preferred Stockholders and the Warrantholders setting forth any and all facts, conditions, occurrences, changes and other matters, in each case, occurring after the date hereof, that has caused or may cause the representations and warranties of CMS Energy contained herein (including the Schedules hereto) not to be true and correct in all respects (in the case of any representation or warranty containing any materiality qualification) or in all material respects (in the case of any representation and warranty without any materiality qualification). In the event that any of such facts, conditions, occurrences, changes and other matters shall have caused or will cause, on or prior to the Effective Date, any such representation or warranty not to be true and correct in all respects (in the case of any representation or warranty containing any materiality qualification) or in all material respects (in the case of any representation and warranty without any materiality qualification) on the Effective Date with the same effect as though made on the Effective Date, Walter may elect to terminate this Agreement pursuant to Section 11.1(e) based on such facts, conditions, occurrences, changes or other matters. If Walter shall nevertheless proceed to consummate the Merger, such facts, conditions, occurrences, changes or other matters so disclosed as to each such representation or warranty of CMS Energy contained herein (including the Schedules) shall be deemed to constitute an exception to such representation or warranty reflecting the facts, conditions, occurrences, changes and other matters so -69- 77 disclosed with the same effect as if such exception had been made in such representation or warranty as of the date hereof in this Agreement to the extent, but only to the extent, of such disclosure. SECTION 10.8. ADJUSTMENT TO CONSIDERATION. All indemnity payments made pursuant to this Article X (other than by or to the Preferred Stockholders) shall be considered as adjustments to the consideration paid in connection with the Merger.

Anything contained in this Agreement to the contrary notwithstanding, this Agreement may be terminated at any time prior to the Effective Date: (a) by the mutual consent of CMS Energy and Walter; (b) by CMS Energy upon any material breach by Walter or any Stockholder or any Preferred Stockholder or any Warrantholder of any of the covenants contained in Article VI or VII or Section 12.1; (c) by Walter upon any material breach by CMS Energy or Sub of any of the covenants contained in Article VI or VII or Section 12.1; (d) by CMS Energy if any of the conditions specified in Article VIII has not been met in all material respects or waived by CMS Energy at such time as such condition can no longer be satisfied; (e) by Walter if any of the conditions specified in Article IX has not been met in all material respects or waived by Walter and the Stockholders, as applicable, at such time as such condition can no longer be satisfied; or (f) by CMS Energy or Walter if the Merger shall not have been consummated on or before February 28, 1995. In the event that this Agreement shall be terminated pursuant to this Section 11.1, all further obligations of the parties under this Agreement (other than Sections 12.1, 12.2 and 12.10) shall terminate without further liability of any party to the others; provided, however, that nothing herein shall relieve any party from liability for its willful breach of this Agreement. -70- 78 ARTICLE XII OTHER PROVISIONS SECTION 12.1.
