This Section 5.1(e) is not intended to create any obligation to provide benefits to any person, but rather, is intended merely to allocate such obligations to the extent they may already exist. To the extent that retiree medical and life insurance benefits are offered to Spinco Participants under the Spinco Welfare Plans pursuant to this Section 5.1(e), such benefits shall be substantially comparable, in the aggregate, to the applicable terms of the retiree medical and life insurance benefits provided to such Spinco Participants under the Parent Welfare Plans as of December 31, 2013.

No later than ninety (90) days following the Distribution Date (or such later time as mutually agreed by Parent and Spinco, and to the extent not already transferred prior to the date hereof), (i) Parent shall cause an amount of Assets held in the 1997 VEBA that bears the same ratio to the total Assets held in the 1997 VEBA that obligations being assumed by Spinco for retiree medical benefits of Spinco Participants under the Parent Welfare Plans bear to all obligations for retiree medical benefits under the Parent Welfare Plans to

be transferred from 1997 VEBA to a corresponding voluntary employee beneficiary association to be established with respect to the Spinco Welfare Plans, and Spinco shall cause such voluntary employee beneficiary association to accept such transfer, provided that Parent shall use commercially reasonable efforts to cause the reinsurance contract held by the 1997 VEBA pursuant to EIS Program 15 to be split into two contracts, one owned by Parent and one owned by Spinco and (ii) Parent shall transfer the 2005 VEBA to Spinco.

(iv) Claim Experience. Claims of Spinco Participants under the Parent Welfare Plans that are incurred but unpaid as of December 31, 2013 may be submitted to the Spinco Welfare Plans for payment, provided that Parent shall reimburse Spinco or the Spinco Welfare Plans, as applicable, for any payments made by Spinco or the Spinco Welfare Plans with respect to such incurred but unpaid claims.

With respect to Spinco Participants, as of the Distribution Date (to the extent not already recognized prior to the date hereof), Spinco shall cause each Spinco Welfare Plan to recognize all elections and designations (including all coverage and contribution elections, beneficiary designations and wellness program designations such as those

related to surcharges and screenings) made by or with respect to Spinco Participants under, or with respect to, the Spinco Welfare Plans or the corresponding Parent Welfare Plan, as applicable, and apply such elections and designations under the Spinco Welfare Plan for the remainder of the period or periods for which such elections or designations are by their original terms applicable, to the extent an election or designation made under a particular Parent Welfare Plan is available under the corresponding Spinco Welfare Plan.

Section 7.2 Treatment of Outstanding Parent Equity Incentive Awards. The Parties shall use commercially reasonable efforts to take all actions necessary or appropriate so that each outstanding Parent Restricted Stock Unit and Parent Performance Unit shall be adjusted as set forth in this Section 7.2.

(a) Parent Restricted Stock Units granted during 2011. Except as set forth in Section 7.2(e), each unvested Parent Restricted Stock Unit granted during 2011 and held by either a Parent Participant or a Spinco Participant on a date to be determined by the Parent Board shall vest in full on such date and be satisfied by Parent in accordance with the terms of the Parent Long-Term Incentive Plan, but in any event no later than the Distribution Record Date.

(i) Held by Parent Participants. Except as set forth in Section 7.2(e), each Parent Restricted Stock Unit that was granted by Parent during 2012 and 2013, that remains outstanding immediately prior to the Distribution Date, and is held by a Parent Participant, shall be equitably adjusted as of the Distribution Date by issuing additional Parent Restricted Stock Units. The total number of Parent Restricted Stock Units held by the Parent Participant following the Distribution shall be equal to the number of Parent Restricted Stock Units held by the Parent Participant that are outstanding immediately prior to the Distribution Date, multiplied by the Parent Ratio and rounded to the nearest whole unit. All adjusted Parent Restricted Stock Units shall become vested upon the date the Parent Restricted Stock Units would have otherwise vested in accordance with the existing vesting schedule.

(ii) Held by Spinco Participants. Except as set forth in Section 7.2(e), each Parent Restricted Stock Unit that was granted by Parent during 2012 and 2013, that remains outstanding immediately prior to the Distribution Date, and is held by a Spinco Participant, shall be converted via cancellation as of the Distribution Date and replacement by an award of Spinco Restricted Stock Units equal to the number of Parent Restricted Stock Units held by the Spinco Participant that are outstanding immediately prior to the Distribution Date, multiplied by the Spinco Ratio and rounded to the nearest whole unit. The replacement Spinco Restricted Stock Units shall vest on the date the Parent Restricted Stock Units would have otherwise vested in accordance with the existing vesting schedule.

(iii) Except as otherwise provided herein, the terms and conditions applicable to the adjusted Parent Restricted Stock Units and Spinco Restricted Stock Units, respectively, shall be substantially similar to the terms and conditions applicable to the corresponding pre-Distribution Parent Restricted Stock Unit (taking into account changes in the identity of the employer, including for purposes of determining whether a change in control has occurred).

(c) Treatment of Outstanding Parent Performance Units Granted During 2011. Except as set forth in Section 7.2(e), each unvested Parent Performance Unit granted during 2011 and held by either a Parent Participant or a Spinco Participant on a date to be determined by the Parent Board shall vest in full and the applicable performance period shall end on such date, and the amount payable, if any, shall equal the total number of Parent Common Shares that would have been issued to the participant for the full performance period, determined using actual performance results as of such date, and shall be paid by Parent in accordance with the terms of the Parent Equity Compensation Plan, but in any event no later than the Distribution Record Date.

(d) Treatment of Outstanding Parent Performance Units Granted During 2012 and 2013.

(i) Held by Parent Participants. Except as set forth in Section 7.2(e), each Parent Performance Unit that was granted by Parent during 2012 and 2013, that remains outstanding immediately prior to the Distribution Date, and is held by a Parent Participant, shall be equitably adjusted as of the Distribution Date by issuing additional Parent Performance Units. The target number of shares subject to the Parent Performance Units held by the Parent Participant following the Distribution shall be equal to the target number of shares subject to the Parent Performance Units held by the Parent Participant that are outstanding immediately prior to the Distribution Date, multiplied by the Parent Ratio and rounded to the nearest whole unit. For purposes of calculating the achievement of the total shareholder return performance metric applicable to the adjusted Parent Performance Units, the Distribution shall be treated as a cash dividend (in an amount equal to the Post-Distribution Price of a share of Spinco Common Stock multiplied by the total number of shares of Spinco Common Stock distributed in the Distribution) with respect to Parent Common Stock that has been paid and reinvested in Parent Common Stock on the Distribution Date at a price per share of Parent Common Stock equal to the Post-Distribution Price of a share of Parent Common Stock. The amount payable, if any, with respect to the Parent Performance Units shall otherwise be determined and paid by Parent in accordance with the terms of the Parent Equity Compensation Plan. In addition, the Parent Board (or any duly authorized committee or representative thereof) may approve further equitable adjustments to such Parent Performance Units to reflect the Distribution as it deems appropriate.

(ii) Held by Spinco Participants. Except as set forth in Section 7.2(e), each Parent Performance Unit that was granted by Parent during 2012 and 2013, that remains outstanding immediately prior to the Distribution Date, and is held by a Spinco Participant, shall be converted via cancellation as of the Distribution Date and replacement with new Spinco Performance Units granted in accordance with the Spinco Equity Compensation Plan, as described (i) in subsection (A) below, with respect to the period between the grant date and the Distribution Date, and (ii) subsection (B) below, with respect to the period between the Distribution Date and the original end of the performance period with respect to the Parent Performance Unit.

(A) The number of new Spinco Performance Units that shall be granted with respect to the period between the grant date and the Distribution Date with respect to the Parent Performance Unit shall equal the target number of Parent Common Shares which would have been issued to the participant for the full performance period, multiplied by (a) the Spinco Ratio, (b) a fraction (rounded to the nearest tenth), the numerator of which is the number of days elapsed between the grant date and the Distribution Date, and the denominator of which is the total number of days in the applicable performance period, and (c) a pre-Distribution payout factor determined using Parent’s relative total shareholder return performance as of the Distribution Date, rounded to the nearest whole share. Each new Spinco Performance Unit granted in accordance with this subsection (A) shall vest on the last day of the performance period to which it relates based on the participant’s service with a member of the Spinco Group through such date, and shall otherwise have the same terms and conditions as the corresponding pre-Distribution Parent Performance Unit.

(B) The number of new Spinco Performance Units that shall be granted with respect to the period between the Distribution Date and the original end of the performance period with respect to the Parent Performance Unit shall equal the target number of Parent Common Shares which would have been issued to the participant for the full performance period, multiplied by both (a) the Spinco Ratio, and (b) a fraction (rounded to the nearest tenth), the numerator of which is the number of days elapsed between the Distribution Date and the last day of the performance period, and the denominator of which is the total number of days in the applicable performance period, rounded to the nearest whole share. Such new Spinco Performance Units shall provide for payment determined using actual performance results from the Distribution Date until the last day of the performance period to which it relates, based on performance criteria to be established by Spinco in accordance with the Spinco Equity Compensation Plan. Each new Spinco Performance Units granted in accordance with this subsection (B) shall otherwise have the same terms and conditions as the corresponding pre-Distribution Parent Performance Unit.

(e) Deferred and Phantom Share Accounts. With respect to the deferred and phantom share accounts maintained under (x) the Parent Stock Plans, in connection with the deferral by participants of the issuance of Parent Common Stock that would have otherwise been issued upon vesting of Parent Restricted Stock Units and Parent Performance Units and (y) the Parent Deferred Compensation Plan for Non-Employee Directors, in connection with the deferral by participants of director compensation in exchange for phantom stock units deemed to represent Parent Common Stock, (1) such deferred and phantom share accounts shall be credited with units equal to that number of shares of Spinco Common Stock that would have been issuable pursuant to the Distribution in accordance with the distribution ratio set forth in the Separation Agreement, (2) such deferred and phantom share accounts shall be maintained following the Distribution by Parent to the extent comprised of Parent units and by Spinco to the extent comprised of Spinco units, and (3) such units shall otherwise remain subject to the prior deferral elections of the holders of such deferred and phantom share accounts and the terms of such plans.

(f) 409A. In all events, the adjustments to the equity awards provided for in this Section 7.2 shall be made in a manner that avoids adverse tax consequences under Code Section 409A.

(g) Allocation of Tax Deduction. Parent shall be entitled to the benefit of the tax deduction in respect of any payment of any Parent Restricted Stock Unit or Parent Performance Unit. Spinco shall be entitled to the benefit of the tax deduction with respect to the payment of any Spinco Restricted Stock Unit or Spinco Performance Unit granted to Spinco Participants pursuant to this Article VII.

The Parties mutually agree to use commercially reasonable efforts to maintain effective registration statements with the SEC with respect to the long-term incentive awards described in this Article VII, to the extent any such registration statement is required by applicable Law.

Section 7.5 Tax Withholding and Reporting for Equity-Based Awards. Except as otherwise provided under Section 8.3(c), Parent (or one of its Affiliates) will be responsible for all income, payroll, or other tax reporting related to income of Parent Employees or Former Parent Employees from equity-based awards, and Spinco (or one of its Affiliates) will be responsible for all income, payroll, or other tax reporting related to income of Spinco Employees or Former Spinco Employees from equity-based awards.

(a) Payroll of Transferring Employees. Except as otherwise mutually agreed upon in writing by Parent and Spinco, in the case of an individual who transferred employment at January 1, 2014 from Parent to Spinco, Spinco shall be responsible for paying the entire payroll amount due such individual for the first payroll cycle ending after January 1, 2014, and for satisfying all applicable tax reporting and withholding requirements in respect of such payment; provided, that, Spinco shall withhold from that first payroll the 401(k) contributions, catch-up contributions, Roth elective deferral contributions and after-tax deposits elected prior to January 1, 2014, by transferring employees under the Parent 401(k) Thrift Plan (“Thrift Plan Contributions”).

Section 10.6 Effect on Employment. Except as expressly provided in this Agreement, the occurrence of the Distribution alone shall not cause any employee to be deemed to have incurred a termination of employment which entitles such individual to the commencement of benefits under any of the Parent Benefit Plans. Furthermore, nothing in this Agreement is intended to confer upon any employee or former employee of Parent or Spinco or any of their respective Affiliates any right to continued employment, or any recall or similar rights to an individual on layoff or any type of approved leave.

Section 10.7 Consent of Third Parties. If any provision of this Agreement is dependent on the Consent of any third party and such consent is withheld, the Parties hereto shall use their reasonable best efforts to implement the applicable provisions of this Agreement to the fullest extent practicable.

Section 10.8 Change in Control; Termination of Employment and Severance. The Parties acknowledge and agree that the Separation and the assignment, transfer or continuation of the employment of Employees as contemplated by the Separation shall not: (i) entitle any Parent Employee or Spinco employee to a distribution or other payment from any Parent Benefit Plan or Spinco Benefit Plan or (ii) entitle any Employee to any severance payments or severance benefits from any member of the Parent Group or the Spinco Group. The Parties acknowledge that the Separation will not constitute a “change in control” for purposes of any Parent Benefit Plan or Spinco Benefit Plan in effect on the Distribution Date, or with respect to any awards, including Parent equity awards, outstanding as of the Distribution Date.

Section 10.9 Access to Employees. Following the Effective Time, Parent and Spinco shall, or shall cause each of their respective Affiliates to, make available to each other those of their employees who may reasonably be needed in order to defend or prosecute any legal or administrative action (other than a legal action between the Parties) to which any employee, director or Benefit Plan of the Parent Group or Spinco Group is a party and which relates to their respective Benefit Plans prior to the Distribution Date. The Party to whom an employee is made

available in accordance with this Section 10.9 shall pay or reimburse the other Party for all reasonable expenses incurred by such employee in connection therewith, including all reasonable travel, lodging, and meal expenses, but excluding any amount for such employee’s time spent in connection herewith.

Section 11.1 Effect if Certain Events do not Occur. Notwithstanding anything in this Agreement to the contrary, if the Separation Agreement is terminated prior to the Effective Time, then all actions and events that are, under this Agreement, to be taken or occur effective prior to, as of or following the Effective Time, or otherwise in connection with the Separation, shall not be taken or occur except to the extent specifically agreed to in writing by the Parties and neither Party shall have any Liability or further obligation to any other Party under this Agreement.

Section 11.3 Subsidiaries.

The Parties acknowledge that certain actions, agreements and obligations that certain of their Affiliates and Subsidiaries may be required to perform in connection with the performance of the Parties’ obligations under this Agreement may require Governmental Approval by Governmental Entities under applicable Law, and therefore agree that performance of such actions, agreements and obligations is subject to the receipt of all such necessary Governmental Approvals, which approvals each Party shall, and shall cause the members of its respective Group to, use its commercially reasonable efforts to obtain.

Section 11.4 Notices. All notices, requests, claims, demands and other communications under this Agreement shall be in writing and shall be given or made (and shall be deemed to have been duly given or made upon receipt unless the day of receipt is not a Business Day, in which case it shall be deemed to have been given on the next Business Day) by delivery in person, by overnight courier service, by facsimile with receipt confirmed (followed by delivery of an original

Section 11.8 Termination.
