4.2           Brokers’ Fees. In connection with the transaction specifically contemplated by this Agreement, no party to this Agreement has employed the services of a broker and each agrees to indemnify the other against all claims of any third parties for fees and commissions of any brokers claiming a fee or commission related to the transactions contemplated hereby.

4.3         Guarantees, Surety Bonds and Letter of Credit Obligations. In the event that Assignor is obligated for any debts, obligations or liabilities of Assignee by virtue of any outstanding guarantee, performance or surety bond or letter of credit provided or arranged by Assignor on or prior to the Closing Date, Assignee shall use its best efforts to cause to be issued replacements of such bonds, letters of credit and guarantees and to obtain any amendments, novations, releases and approvals necessary to release and discharge fully Assignor from any liability thereunder following the Closing. Assignee shall be responsible for, and shall indemnify, hold harmless and defend Assignor from and against, any costs or losses incurred by Assignor arising from such bonds, letters of credit and guarantees and any liabilities arising therefrom and shall reimburse Assignor for any payments that Assignor may be required to pay pursuant to enforcement of its obligations relating to such bonds, letters of credit and guarantees.

4.4         Agreements Regarding Taxes.

(a)          Tax Sharing Agreements. Any tax sharing agreement between Assignor and Assignee is terminated as of the Closing Date and will have no further effect for any taxable year (whether the current year, a future year or a past year).

(b)          Returns for Periods through the Closing Date. Assignor will include the income and loss of Assignor on Assignor’s federal income tax returns for all periods through the Closing Date and pay any federal income taxes attributable to such income. Assignor will include the income and loss of Assignee on Assignee’s federal income tax returns for all periods through the Closing Date and pay any federal income taxes attributable to such income. Assignor and Assignee agree to allocate income, gain, loss, deductions and credits between the period up to Closing (the “Pre-Closing Period”) and the period after Closing based on a closing of the books of Assignor and Assignee, respectively, and both Assignor and Assignee agree not to make an election under Reg. §1.1502-76(b)(2)(ii) to ratably allocate the year’s items of income, gain, loss, deduction and credit. Assignor and Assignee agree to report all transactions not in the ordinary course of business occurring on the Closing Date after the Closing on Assignor’s and Assignee’s tax returns, as appropriate, to the extent permitted by applicable federal tax law. Assignee agrees to indemnify Assignor for any additional tax owed by Assignor (including tax owed by Assignor due to this indemnification payment) resulting from any transaction engaged in by Assignee or Assignor (not related to the Assignment) during the Pre-Closing Period or on the Closing Date before the Closing. Assignee will furnish tax information to Assignor for inclusion in Assignor’s consolidated federal income tax return for the period which includes the Closing Date in accordance with Assignee’s past custom and practice.

(c)          Audits. Assignor will allow Assignee and its counsel to participate at Assignee’s expense in any audit of Assignor’s consolidated federal income tax returns to the extent that such audit raises issues that relate to and increase the tax liability of Assignee. Assignor shall have the absolute right, in its sole discretion, to engage professionals and direct the representation of Assignor in connection with any such audit and the resolution thereof, without receiving the consent of Assignee or any other party acting on behalf of Assignee, provided that Assignor will not settle any such audit in a manner which would materially adversely affect Assignee after the Closing Date unless such settlement would be reasonable in the case of a person that owned Assignee both before and after the Closing Date. In the event that after Closing any tax authority informs Assignee of any notice of proposed audit, claim, assessment or other dispute concerning an amount of taxes which pertain to Assignor, or to Assignee during the period prior to Closing, Assignee must promptly notify Assignor of the same within 15 calendar days of the date of the notice from the tax authority. In the event Assignee does not notify Assignor within such 15 day period, Assignee will indemnify Assignor for any incremental interest, penalty or other assessments resulting from the delay in giving notice. To the extent of any conflict or inconsistency, the provisions of this Section 10.8 shall control over the provisions of Section 12.2 below.

(d)          Cooperation on Tax Matters. Assignor and Assignee shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of tax returns pursuant to this Section and any audit, litigation or other proceeding with respect to taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Assignee shall (i) retain all books and records with respect to tax matters pertinent to Assignee and Assignor relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Assignor, any extensions thereof) of the respective taxable periods, and abide by all record retention agreements entered into with any taxing authority, and (ii) give Assignor reasonable written notice prior to transferring, destroying or discarding any such books and records and, if Assignor so requests, Assignee will allow Assignor to take possession of such books and records.

V.          MISCELLANEOUS.

5.2           Exercise of Rights and Remedies. Except as otherwise provided herein, no delay of or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default by any other party under this Agreement shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default occurring before or after that waiver.

5.3           Time. Time is of the essence with respect to this Agreement.

5.4           Reformation and Severability. In case any provision of this Agreement shall be invalid, illegal or unenforceable, it shall, to the extent possible, be modified in such manner as to be valid, legal and enforceable but so as to most nearly retain the intent of the parties, and if such modification is not possible, such provision shall be severed from this Agreement, and in either case the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby.

5.5           Further Acts and Assurances. From and after the Closing, Assignor and Assignee agree that each will act in a manner supporting compliance, including compliance by its Affiliates, with all of its obligations under this Agreement and, from time to time, shall, at the request of the other party hereto, and without further consideration, cause the execution and delivery of such other instruments of conveyance, transfer, assignment or assumption and take such other action or execute such other documents as such party may reasonably request in order more effectively to convey, transfer to and vest in Assignee, and to put Assignee in possession of, all Assigned Assets and Assigned Liabilities, and, in the case of any contracts and rights that cannot be effectively transferred without the consent or approval of another person that is unobtainable, to use its best reasonable efforts to ensure that Assignee receives the benefits thereof to the maximum extent permissible in accordance with applicable law or other applicable restrictions, and shall perform such other acts which may be reasonably necessary to effectuate the purposes of this Agreement.

5.6           Entire Agreement; Amendments. This Agreement contains the entire understanding of the parties relating to the subject matter contained herein.

Each party to the Agreement also agrees not to bring any action arising out of or relating to this Agreement in any other court. Each party to the Agreement agrees that a final judgment in any action so brought will be conclusive and may be enforced by action on the judgment or in any other manner provided at law or in equity.
