4.2 Transactions.

(a) It is the intent of the parties that:

(i) The transactions contemplated hereby and the Merger Agreement provide that the Subject Units held by the Blocker Entity are excluded from the effect of the Merger and will be treated as sale of the Blocker Interests to a directly wholly owned subsidiary of Parent for all U.S. federal income tax purposes and not as sale of the underlying Subject Units held by the Blocker Entity.

(iii) Each Parent Indemnified Person shall have no greater and no fewer rights or obligations with respect to the transactions, agreements, covenants, indemnities and other provisions of the Merger Agreement than such Parent Indemnified Person would have had if, immediately prior to the Effective Time, the Units held by the Blocker Entity had instead been held directly by such Selling Equityholder (in proportion to such Selling Equityholder’s interest in the Blocker Entity) and been acquired by the Parent by virtue of the Merger pursuant to the Merger Agreement; provided, however, that nothing herein shall limit the rights or obligations of any Parent Indemnified Person with respect to such Blocker Entity as expressly provided in this Agreement.

(b) Each party shall take such other actions and execute such other agreements as are reasonably necessary to assure that the transactions contemplated by the Merger Agreement and this Agreement, when taken together, equitably reflect the relative rights and obligations of the respective

parties (including the rights of the Parent Indemnified Persons and the Unitholders under the Merger Agreement) and the intent of the parties described in this Section 4.2.

(c) Without limiting the generality of the foregoing and notwithstanding anything contained in this Agreement or in the Merger Agreement to the contrary, none of the Parent Indemnified Persons shall have any obligations (including indemnity obligations) with respect to the ownership of the Subject Units or as a Unitholder under the Merger Agreement.

(b) Notwithstanding any provision of this Agreement to the contrary, the Selling Equityholders' obligation to indemnify Parent or Parent Indemnified Persons for any Tax shall be limited to any Tax properly attributable to taxable periods or portions thereof, ending on or before the Closing Date, excluding any Taxes due as a result of actions taken by Parent or a Parent Indemnified Person pursuant to Section 5.13 of the Merger Agreement or after the Closing.

7.3 Responsibility for Filing Tax Returns. Parent shall prepare or cause to be prepared and file or cause to be filed all Pre-Closing Tax Returns for the Blocker Entity that are filed after the Closing Date, other than income Tax Returns with respect to periods for which a consolidated, unitary or combined income Tax Return of a Selling Equityholder will include the operations of the Blocker Entity.

Selling Equityholders to review, comment, and approve each such income Tax Return described in the preceding sentence prior to filing.

The fees, costs and expenses of the Independent Accountants shall be allocated equally between the Selling Equityholder and Parent.

Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that 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. The Blocker Entity and Selling Equityholders agree (A) to retain all books and records with respect to Tax matters pertinent to the Blocker Entity relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Parent or the Selling Equityholders, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Blocker Entity or Parent, as the case may be, shall allow the other party to take possession of such books and records.

(b) Parent and the Selling Equityholders further agree, upon request, to use their best efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(c) Parent and Selling Equityholders further agree, upon request, to provide the other party with all information that either party may be required to report pursuant to Code §6043, or Code §6043A, or Treasury Regulations promulgated thereunder.

7.6 Tax-Sharing Agreements. All tax-sharing agreements or similar agreements with respect to or involving the Blocker Entity shall be terminated as of the Closing Date and, after the Closing Date, the Blocker Entity shall not be bound thereby or have any liability thereunder.

7.7 Certain Taxes and Fees. All transfer, value added, excise, stock transfer, stamp, recording, registration and similar Taxes incurred in connection with the consummation of the transactions contemplated by this Agreement shall be borne fifty percent (50%) by Parent and fifty percent (50%) by the Selling Equityholders.

7.8 Tax Controversies. If any Government entity issues to the Blocker Entity a written notice of its intent to audit, examine or conduct a proceeding with respect to Taxes or Tax Returns of the Blocker Entity for periods prior to the Effective Time (a “Tax Claim”) Parent shall notify the Selling Equityholders of its receipt of such communication within thirty (30) business days following receipt. The Selling Equityholders shall have the right at their sole cost and expense to control any examination, investigation, audit, or other proceeding in respect of any Tax Claim involving Taxes for which the Selling Equityholders are responsible (a “Tax Contest”), provided that (i) Parent, at its sole cost and expense, shall have the right to participate in any such Tax Contest, and to the extent relating to Taxes or a Tax Return for a Straddle Period or Taxes of the Blocker Entity for which Parent is responsible, shall jointly control the Tax Contest, and (ii) the Selling Equityholders (or Parent, to the extent that the Selling Equityholders decline to exercise their right to control a Tax Contest) shall not settle or otherwise resolve any Tax Claim without the prior written consent of Parent (or the Selling Equityholders, to the extent that the Selling Equityholders decline to exercise their right to control a Tax Contest), which consent will not be unreasonably withheld, conditioned or delayed.

7.9 Except as required by Law, Parent shall not (and, after the Closing, shall not allow the Blocker Entity, to) amend any Tax Return for a taxable period ending on or prior to the Closing Date or any Straddle Period, without the prior written consent of the Selling Equityholders (which consent will not be unreasonably withheld, conditioned or delayed) if the effect of such amended Tax Return is to increase Taxes payable by the Selling Equityholders or Taxes for which the Selling Equityholders are liable.
