CRC, NYC and PRR will allocate the amounts of any CRC Insurance Recoveries or PRP Recoveries among the NYC Assets Historic Environmental Liabilities, the PRR Assets Historic Environmental Liabilities, and all other CRC Environmental Liabilities, consistent with Section 2.11 as amended. The PRR Advances and the NYC Advances shall be non-recourse loans payable only as provided herein. The PRR Advances and the NYC Advances (a) shall be recorded and reported for all tax purposes as loans by the parties hereto and (b) may be contributed, in whole or in part, to the capital of CRC at such time as NSR, in the case of the PRR Advances, and CSXT, in the case of the NYC Advances, shall determine.

(v) CRC shall repay PRR Advances to the extent of the sum of (a) CRC Insurance Recoveries and PRP Recoveries allocated to the PRR Assets Historic Environmental Liabilities and (b) the tax benefits realized by the consolidated group of which CRC is a member, after taking into account the income, if any, reported by such consolidated group with respect to the amounts referred to in clause (a) of this sentence, in respect of (1) the PRR Assets Historic Environmental Liabilities, (2) the PRP Recovery Costs and CRC Insurance Recovery Costs associated with the PRR Assets Historic Environmental Liabilities and (3) accrued interest on the PRR Advances.

(viii) Effective as of the Closing Date, (A) CRC has delegated to NYC exclusive authority and control over the investigation, prosecution, defense and appeal of all Actions (other than Actions seeking CRC Insurance Recoveries) relating to the NYC Assets Historic Environmental Liabilities, but NYC and CRC shall cooperate in the investigation, prosecution, defense, settlement and appeal of any such Action as appropriate; and (B) CRC has delegated to PRR exclusive authority and control over the investigation, prosecution, defense and appeal of all Actions (other than Actions seeking CRC Insurance Recoveries) relating to the PRR Assets Historic Environmental Liabilities, but PRR and CRC shall cooperate in the investigation, prosecution, defense, settlement and appeal of any such Action as appropriate. No settlement or consent judgment that would result in CRC Environmental Liabilities shall be agreed upon without the prior consent of CRC, which consent shall not be unreasonably withheld.

SECTION D. No Forfeiture of Insurance Rights. Section 2.11 of the Transaction Agreement is hereby amended by adding the following to the end of the existing provision:

For the avoidance of doubt, the parties hereto intend to preserve all rights, remedies and claims under any policy or policies of insurance that would have been available to CRR Parent, CRC or their respective Affiliates in the absence of the Merger Agreement, this Agreement or any other related agreement. If any Liability covered by a policy of insurance carried by CRR Parent, CRC or their respective Affiliates on or prior to the Closing Date is held to have been transferred to another Person, then the original insureds under such policy of insurance shall be deemed to have assigned to that Person their rights of recovery under such policy solely to the extent necessary to preserve all insurance-related rights, remedies and claims relating to such Liability; and that Person in turn shall be deemed to have authorized CRC as its sole agent to enforce any such assigned rights of recovery on its behalf. Nothing in the Merger Agreement, this Agreement or any other related agreement shall be construed to waive or in any way to effect a forfeiture of any insurance-related rights, remedies or claims that would have been available to CRR Parent, CRC or their respective Affiliates in the absence of such agreements.

SECTION E. Confirmation of Transaction Agreement. In all respects not inconsistent with the terms and provisions of this Amendment, the Transaction Agreement is hereby ratified, adopted, approved and confirmed.

SECTION F. Miscellaneous. This Amendment is not intended to confer any rights or privileges upon third parties, and no third party is intended to be a third-party beneficiary of this Amendment.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be duly executed, with effect as of the date first above written.
