In the event that any such transfer or assumption of Assets or Liabilities has not been consummated from and after the Effective Time (i) the Party (or relevant member in its Group) retaining such Asset shall thereafter hold (or shall cause such member in its Group to hold) such Asset for the use and benefit of the Party (or relevant member in its Group) entitled thereto (at the expense of the Person entitled thereto) and (ii) the Party intended to assume such Liability shall, or shall cause the applicable member of its Group to, pay or reimburse the Party (or the relevant member of its Group) retaining such Liability for all amounts paid or incurred in connection with the retention of such Liability.

(b) If and when the Consents, Governmental Approvals and/or conditions, the absence or non-satisfaction of which caused the deferral of transfer of any Asset or assumption of any Liability pursuant to Section 2.7(a) , are obtained or satisfied, the transfer, assignment or novation of the applicable Asset or Liability shall be effected in accordance with and subject to the terms of this Agreement and/or the applicable Ancillary Agreement as promptly as practical after the receipt of such Consents, Governmental Approvals and/or absence or satisfaction of conditions.

(c) The Party (or relevant member of its Group) retaining any Asset or Liability due to the deferral of the transfer or assignment of such Asset or the deferral of the assumption of such Liability pursuant to Section 2.7(a) shall not be obligated, in connection with the foregoing, to expend any money unless the necessary funds are advanced, or agreed in advance to be reimbursed by the Party (or relevant member of its Group) entitled to such Asset, other than reasonable attorneys’ fees and recording or similar fees, all of which shall be promptly reimbursed by the Party entitled to such Asset (or relevant member of its Group).

In connection with such transfer, contribution, assignment, distribution or conveyance, the receiving party shall assume all Liabilities related to such asset. Following the twenty-four (24) month anniversary of the Effective Time, no Party (or relevant member of its Group) shall be obligated to transfer any newly recognized Asset that would, had such Asset been recognized at the Effective Time, have been transferred to the other Party (or relevant member of its Group).

(e) After the Effective Time, each Party (or any member of its Group) may receive mail, telegrams, packages and other communications properly belonging to the other Party (or any member of its Group). Accordingly, at all times after the Effective Time, each Party authorizes the other Party (or any member of its Group) to receive and open all mail, telegrams, packages and other communications received by such Party (or any member of its Group) and not unambiguously intended for such first Party, any member of such first Party’s Group or any of their respective officers, directors, employees or other agents, and to the extent that they do not relate to the business of the receiving Party, the receiving party shall promptly deliver such mail, telegrams, packages or other communications (or, in case the same relate to both businesses, copies thereof) to the other Party as provided for in Section 11.6 . The provisions of this Section 2.7(e) are not intended to, and shall not, be deemed to constitute an authorization by any Party (or any member of its Group) to permit the other to accept service of process on its (or its members’) behalf and no Party (or any member of its Group) is or shall be deemed to be the agent of the other Party (or any member of its Group) for service of process purposes.

Section 2.8. Conveyancing and Assumption Instruments .

(b) Without limiting the foregoing, each Party shall cooperate with the other Party, from and after the Effective Time, to execute and deliver, or use commercially reasonable efforts to cause to be executed and delivered, all instruments, including instruments of conveyance, assignment and transfer, and to make all filings with, and to obtain all Consents and/or Governmental Approvals, any permit, license, Contract, indenture or other instrument (including any Consents or Governmental Approvals), and to take all such other actions as such Party may reasonably be requested to take by any other Party from time to time, consistent with the terms of this Agreement and the Ancillary Agreements, in order to effectuate the provisions and purposes of this Agreement and the Ancillary Agreements and the conveyances, assignments and transfers of the applicable Assets and the assignment and assumption of the applicable Liabilities and the other transactions contemplated hereby and thereby. Without limiting the foregoing, each Party will, at the reasonable request, of the other Party, take such other actions as may be reasonably necessary to vest in such other Party good and marketable title to the Assets allocated to such Party under this Agreement or any of the Ancillary Agreements, free and clear of any Security Interest, if and to the extent it is practicable to do so.

Section 2.10. Novation of Liabilities; Consents .

(b) If the Parties are unable to obtain, or to cause to be obtained, any such required Consent, release, substitution or amendment, the Other Party or a member of such Other Party’s Group shall continue to be bound by such Contract, license or other obligation that does not constitute a Liability of such Other Party and, unless not permitted by Law or the terms thereof, as agent or subcontractor for such Party, the Party or member of such Party’s Group who assumed or retained such Liability as set forth in this Agreement (the " Liable Party ") shall, or shall cause a member of its Group to, pay, perform and discharge fully all the obligations or other Liabilities of such Other Party or member of such Other Party’s Group thereunder from and after the Effective Time; provided , however , that the Other Party shall not be obligated to extend, renew or otherwise cause such Contract, license or other obligation to remain in effect beyond

33

the term in effect as of the Effective Time. The Liable Party shall indemnify each Other Party and the members of such Other Party’s Group and hold each of them harmless against any and all Liabilities arising in connection therewith; provided , that the Liable Party shall have no obligation to indemnify the Other Party or any member of such Other Party’s Group with respect to any matter to the extent that such Other Party has engaged in any knowing violation of Law, fraud or misrepresentation in connection therewith. The Other Party shall, without further consideration, promptly pay and remit, or cause to be promptly paid or remitted, to the Liable Party or to another member of the Liable Party’s Group, all money, rights and other consideration received by it or any member of its Group in respect of such performance by the Liable Party (unless any such consideration is an Asset of such Other Party pursuant to this Agreement). If and when any such Consent, release, substitution or amendment shall be obtained or such agreement, lease, license or other rights or obligations shall otherwise become assignable or able to be novated, the Other Party shall promptly assign, or cause to be assigned, all rights, obligations and other Liabilities thereunder of any member of such Other Party’s Group to the Liable Party or to another member of the Liable Party’s Group without payment of any further consideration and the Liable Party, or another member of such Liable Party’s Group, without the payment of any further consideration, shall assume such rights and Liabilities.
