SECTION 4.                                DECONSOLIDATION AND DISTRIBUTION TAXES

4.1                                 CONTINUING COVENANTS. Mueller, for itself and the Mueller Affiliates, covenants that on or after a Deconsolidation it will not (nor will it cause or permit any member of the Mueller Group ), in respect of any Pre-Deconsolidation Period, (i) make or change any tax election, (ii) change any accounting method, (iii) amend any Tax Return or take any Tax position on any Tax Return that is inconsistent with any Tax position on any Tax Return of the Walter Group, or (iv) take any action, omit to take any action or enter into any transaction that results in any increased Tax liability or reduction of any Tax Asset of the Walter Group.

4.2                                 ADDITIONAL CONTINUING COVENANTS. (a)  MUELLER RESTRICTIONS. Mueller agrees that, until such time as the stock of Mueller owned by Walter and Walter Affiliates constitutes fifty percent (50%) or less of the total combined voting power of all of the outstanding stock of Mueller, Mueller (1) will not knowingly take or fail to take, or permit any Mueller Affiliate to knowingly take or fail to take, any action that could reasonably be expected to preclude Walter’s ability to effectuate a Distribution, and (2) will not issue any stock of Mueller (or any instrument that is convertible, exercisable or exchangeable into any such stock) in an acquisition or public or private offering if, immediately after such issuance, Walter would, or would reasonably be expected to, not own stock of Mueller that, on a fully diluted basis, constitutes “control” (within the meaning of Section 368(c) of the Code) of Mueller. In the event of a Distribution, Mueller agrees that (1) it will take, and cause each Mueller Affiliate to take, any action reasonably requested by Walter in order to enable Walter to effectuate a Distribution (including, without limitation, any internal restructuring necessary to satisfy the active trade or business requirement of Section 355(b) of the Code) and (2) it will not take or fail to take, or permit any Mueller Affiliate to take or fail to take, any action where such action or failure to act would be inconsistent with any written representations of an officer of Mueller pursuant to Section 4.2(e) of this Agreement with respect to any material, information, covenant or representation that relates to facts or matters related to Mueller, any Mueller Affiliate, or the Mueller Business in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling other than as

10

permitted by Section 4.2(c) of this Agreement. For this purpose an action is considered inconsistent with a representation if the representation states that there is no plan or intention to take such action. In the event of a Distribution, Mueller agrees that it will not take (and it will cause the Mueller Affiliates to refrain from taking) any position on a Tax Return that is inconsistent with the treatment of a Distribution as a tax-free transaction under Section 355 of the Code.

(b)                                 WALTER RESTRICTIONS. In the event of a Distribution, Walter agrees that it will not take or fail to take, or permit any Walter Affiliate to take or fail to take, any action where such action or failure to act would be inconsistent with any material, information, covenant or representation that relates to facts or matters related to Walter (or any Walter Affiliate) or within the control of Walter and is contained in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling. For this purpose an action is considered inconsistent with a representation if the representation states that there is no plan or intention to take such action. In the event of a Distribution, Walter agrees that it will not take (and it will cause the Walter Affiliates to refrain from taking) any position on a Tax Return that is inconsistent with the treatment of a Distribution as a tax-free transaction under Section 355 of the Code.

(c)                                  CERTAIN MUELLER ACTIONS FOLLOWING A DISTRIBUTION. In the event of a Distribution, Mueller agrees that, during the 2-year period following a Distribution, without first obtaining, at Mueller’s own expense, either a supplemental opinion from Tax Counsel that such action will not result in Distribution Taxes (a “Supplemental Tax Opinion”) or a Supplemental Ruling that such action will not result in Distribution Taxes, unless in any such case Walter and Mueller agree otherwise, Mueller shall not (1) sell all or substantially all of the assets of Mueller or any Mueller Affiliate, (2) merge Mueller or any Mueller Affiliate with another entity, without regard to which party is the surviving entity, (3) transfer any assets of Mueller in a transaction described in Section 351 (other than a transfer to a corporation which files a consolidated return with Mueller and which is wholly-owned, directly or indirectly, by Mueller) or subparagraph (C) or (D) of Section 368(a)(1) of the Code, (4) issue stock of Mueller or any Mueller Affiliate (or any instrument that is convertible or exchangeable into any such stock) in an acquisition or public or private offering, or (5) facilitate or otherwise participate in any acquisition of stock in Mueller that would result in any shareholder owning five percent (5%) or more of the outstanding stock of Mueller. Mueller or any Mueller Affiliate shall only undertake any of such actions after Walter’s receipt of such Supplemental Tax Opinion or Supplemental Ruling and pursuant to the terms and conditions of any such Supplemental Tax Opinion or Supplemental Ruling or as otherwise consented to in writing in advance by Walter. The parties hereby agree that they will act in good faith to take all reasonable steps necessary to amend this Section 4.2(c), from time to time, by mutual agreement, to (i) add certain actions to the list contained herein, or (ii) remove certain actions from the list contained herein, in either case, in order to reflect any relevant change in law, regulation or administrative interpretation occurring after the date of this Agreement.

(d)                                 NOTICE OF SPECIFIED TRANSACTIONS. Not later than 30 days prior to entering into any oral or written contract or agreement, and not later than 5 days after it first becomes aware of any negotiations, plan or intention (regardless of whether it is a party to such negotiations, plan or intention), regarding any of the transactions described in Section 4.2(c) of this Agreement, Mueller shall provide written notice of its intent to consummate

11

such transaction or the negotiations, plan or intention of which it becomes aware, as the case may be, to Walter.

(e)                                  MUELLER COOPERATION. Mueller agrees that, at the request of Walter, Mueller shall cooperate fully with Walter to take any action necessary or reasonably helpful to effectuate a Distribution, including seeking to obtain, as expeditiously as possible, a Tax Opinion, Supplemental Tax Opinion, Ruling, and/or Supplemental Ruling. Such cooperation shall include the execution of any documents that may be necessary or reasonably helpful in connection with obtaining any Tax Opinion, Supplemental Tax Opinion, Ruling, and/or Supplemental Ruling (including, without limitation, any (i) power of attorney, (ii) Officer’s Certificate, (iii) Ruling Documents, (iv) Supplemental Rulings Documents, and/or (v) reasonably requested written representations confirming that (a) Mueller has read the Officer’s Certificate, Ruling Documents, and/or Supplemental Ruling Documents and (b) all information and representations, if any, relating to Mueller, any Mueller Affiliate, or the Mueller Business contained in the Officer’s Certificate, Ruling Documents, and/or Supplemental Ruling Documents are true, correct and complete in all material respects).

4.3                                 DISTRIBUTION TAXES. The parties have set forth how certain Tax matters with respect to a Distribution would be handled in the event that a Distribution is pursued at some future time.

(a)                                  WALTER’S LIABILITY FOR DISTRIBUTION TAXES. In the event of a Distribution, notwithstanding Section 3 of this Agreement, Walter and each Walter Affiliate shall be jointly and severally liable for any Distribution Taxes, to the extent that such Distribution Taxes are attributable to, caused by, or result from, one or more of the following:

(1)                                  any action or omission by Walter (or any Walter Affiliate) inconsistent with any material, information, covenant or representation related to Walter, any Walter Affiliate, or the Walter Business in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling (for the avoidance of doubt, disclosure of any action or fact that is inconsistent with any material, information, covenant or representation submitted to Tax Counsel, the IRS, or other Tax Authority, as applicable, in connection with an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling shall not relieve Walter (or any Walter Affiliate) of liability under this Agreement);

(2)                                  any action or omission by Walter (or any Walter Affiliate), including a cessation, transfer to affiliates, or disposition of its active trades or businesses, or an issuance of stock, stock buyback or payment of an extraordinary dividend by Walter (or any Walter Affiliate) following a Distribution;

(3)                                  any acquisition of any stock or assets of Walter (or any Walter Affiliate) by one or more other persons (other than Mueller or a Mueller Affiliate) prior to or following a Distribution; or

(4)                                  any issuance of stock by Walter (or any Walter Affiliate).

(b)                                 MUELLER’S LIABILITY FOR DISTRIBUTION TAXES. In the event of a Distribution, notwithstanding Section 3 of this Agreement, Mueller and each Mueller Affiliate shall be jointly and severally liable for any Distribution Taxes, to the extent that

12

such Distribution Taxes are attributable to, caused by, or result from, one or more of the following:

(1)                                  any action or omission by Mueller (or any Mueller Affiliate) after a Distribution at any time, that is inconsistent with any written representations of an officer of Mueller pursuant to Section 4.2(e) of this Agreement with respect to any material, information, covenant or representation related to Mueller, any Mueller Affiliate, or the Mueller Business in an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling (for the avoidance of doubt, disclosure by Mueller (or any Mueller Affiliate) to Walter (or any Walter Affiliate) of any action or fact that is inconsistent with any material, information, covenant or representation submitted to Tax Counsel, the IRS, or other Tax Authority, as applicable, in connection with an Officer’s Certificate, Tax Opinion, Supplemental Tax Opinion, Ruling Documents, Supplemental Ruling Documents, Ruling, or Supplemental Ruling shall not relieve Mueller (or any Mueller Affiliate) of liability under this Agreement);

(2)                                  any action or omission by Mueller (or any Mueller Affiliate) after the date of a Distribution (including any act or omission that is in furtherance of, connected to, or part of a plan or series of related transactions (within the meaning of Section 355(e) of the Code) occurring on or prior to the date of a Distribution) including a cessation, transfer to affiliates or disposition of the active trades or businesses of Mueller (or any Mueller Affiliate), stock buyback or payment of an extraordinary dividend;

(3)                                  any acquisition of any stock or assets of Mueller (or any Mueller Affiliate) by one or more other persons (other than Walter or any Walter Affiliate) prior to or following a Distribution; or

(4)                                  any issuance of stock by Mueller (or any Mueller Affiliate) after a Distribution, including any issuance pursuant to the exercise of employee stock options or other employment related arrangements or the exercise of warrants.

(c)                                  JOINT LIABILITY FOR REMAINING DISTRIBUTION TAXES. Walter and each Walter Affiliate shall be liable for a percentage of any Distribution Taxes (not otherwise allocated by Sections 4.3(a) or (b) of this Agreement) equal to the quotient of (i) Walter’s Market Valuation, divided by (ii) the sum of (x) Walter’s Market Valuation, and (y) Mueller’s Market Valuation. Mueller and each Mueller Affiliate shall be jointly and severally liable for a percentage of any Distribution Taxes (not otherwise allocated by Sections 4.3(a) or (b) of this Agreement) equal to the quotient of (i) Mueller’s Market Valuation, divided by (ii) the sum of (x) Walter’s Market Valuation, and (y) Mueller’s Market Valuation.

This Agreement shall be binding on and inure to the benefit of any successor, by merger, acquisition of assets or otherwise, to any of the parties hereto (including any successor of Walter and Mueller succeeding to the tax attributes of such party under Section 381 of the Code), to the same extent as if such successor had been an original party.

Each of the parties hereto hereby represents and warrants that it has the power and authority to execute, deliver and perform this Agreement, that this Agreement has been duly authorized by all necessary corporate action on the part of such party, that this Agreement constitutes a legal, valid and binding obligation of each such party and that the execution, delivery and performance of this Agreement by such party does not contravene or conflict with any provision of law or of its charter or bylaws or any agreement, instrument or order binding on such party.
