Canadian Defined Contribution plan;

Canadian ancillary programs (life insurance, disability and executive medical programs);

Canadian beer program; and

Canadian auto program

Healthcare. You and your family will be permitted to remain in Molson Coors’ healthcare plan for US employees after your family relocates to Toronto. You will be required to pay the employee cost of this coverage as if you were a US employee. You may terminate this benefit at any time by notifying the company. At that time, your split payroll will cease and the US portion moved to the Canadian payroll. You will also continue to be eligible for the executive physical program applicable to US-based ELT members.

SERP. You will participate in a defined contribution supplemental executive retirement plan (SERP) effective as of February 1, 2013. You were previously provided details of this plan in your agreement attached as Exhibit A to this letter.

Relocation Costs. The company will cover your relocation costs , including a guaranteed buyout offer on your Denver-area home, if triggered on or before August 29, 2015 as well as an allowance in an amount as agreed to by the company. Note that the guaranteed buyout provision will require that we start the home sale process approximately 120 - 180 days before the August 29, 2015 deadline in order to trigger the guaranteed buyout by the company, if necessary. Below are additional provisions related to this relocation benefit:

In order to receive the full benefits of the relocation policy, do not make contact with a real estate agent in either the old or new location before speaking with your Relocation Consultant (do not execute a listing agreement or a home purchase contract).

The company will provide you and your family with housing in the Toronto, ON area for a period up to the earlier of: (a) two years (ending August 29, 2015) and (b) the date of sale of your home in Evergreen, CO. General market data would suggest a monthly benefit of CAD 8,000 per month, but we have agreed to an allowance of CAD 7,500 per month. You will be grossed up for any taxes associated with this benefit.

You and your family will be entitled to certain travel benefits between Toronto and Denver to allow you to facilitate the sale of your Evergreen, CO home. This benefit is limited to four trips per family member. However, should you require additional trips, the parties can mutually agree in writing to add additional trips.

These trips should be booked through Concur (Carlson Wagonlit Travel) but should be paid by personal credit card and submitted to Weichert for reimbursement. These costs will not be grossed up for taxes.

Your countersignature below serves as acknowledgement that the company has paid or will pay certain expenses resulting from your relocation. You may begin using these services immediately upon the effective date of your assignment. However, you must complete the utilization of this benefit no later than February 1, 2015. In exchange for the payment of such expenses, you agree that, if you voluntarily terminate your employment with the company on

In the event it is necessary to reclaim any relocation benefit payments, you authorize the company to set off the amount(s) you owe against any compensation or other sums the company owes you. If such deductions are not sufficient to cover the full amount of the sign-on bonus or relocation benefit payments, you promise to pay to the company the remaining balance within 10 working days of your departure from the company.

Tax Preparation Services. In accordance with your standard practice, you will be provided with tax preparation services for the 2012 and 2013 US, Canada and UK tax years (2012/2013 tax year for the UK). These services will be provided by the company’s external tax provider, currently Ernst & Young.

Vacation. There is no change to your vacation benefit, which is restated below. You are entitled to 5 weeks’ vacation per year, which will be administered in accordance with the company’s vacation policy.

Termination. There is no change to your severance benefit. In the event of your involuntary termination by the company, other than for just cause (as defined in the Change in Control Protection Program), you will be eligible for a severance payment (“Normal Severance”), in the form of a continuation of your base salary equal to 12 months (the “Severance Period”). You will not be entitled to any compensation on account of lost annual bonus (MCIP) payments for the Severance Period, but shall be eligible for MCIP bonus payments prorated for any part of service up to the date of commence of the Severance Period. In addition, all your existing insured benefits (excluding short and long-term disability) and perquisites will be continued during the Severance Period or until you find new employment or self-employment whichever occurs first. You will continue to accrue pension service during the Severance period or until you find new employment or self-employment whichever occurs first.

Change in Control Program. There is no change to your right to participate in the Amended and Restated Change in Control Protection Program, dated effective January 1, 2008, as amended. This program is prescribed by the MCBC Board of Directors and provides economic protection in the event of a change in the control of Molson Coors Brewing Company and your employment termination within two years following such change in control. We encourage you to review the program documents in detail but at a high level, the economic protection under this program includes, among other provisions, a payment equal to three times the sum of your annual base salary and your target incentive as well as accelerated vesting of your outstanding, MCBC granted shares. This program is for the special circumstances associated with a change in the control of the company and is thus, not additive to "normal severance."

Molson Coors Canada (“Molson”) provides a registered defined contribution pension plan to its salaried employees, the Molson Canada Pension Plan for Salaried Employees (the “Registered Plan”). Contributions under the Registered Plan are subject to the Income Tax Act (Canada) limits.

Molson also provides an unregistered defined contribution pension plan to its salaried employees (the “Unregistered Plan”) for the portion of the employer contributions under the Registered Plan provisions which would not otherwise be made, due to the limits imposed by the Income Tax Act (Canada).

In addition, Molson shall provide you a complementary arrangement (the “DC SERP”) where notional allocations are made to a notional individual account maintained by Molson in your name (the “Supplemental Account”).

You shall become entitled to benefits under the DC SERP from the date you became a member of the Registered Plan. You shall accrue benefits under the DC SERP as long as you remain a member of the Registered Plan.

In respect of each month during which you accrued benefits under the DC SERP, Molson shall make a notional allocation to your Supplemental Account in an amount equal to 16% of your monthly earnings, less what Molson contributed in your respect to the Registered DC Plan during such month.

The amount of notional allocations shall not be taken into account for the calculation of any other benefits, bonuses or other advantages paid by Molson.

For the purposes of calculating notional investment income under your Supplemental Account, the notional allocations made by Molson to your Supplemental Account shall be credited with a rate of return corresponding to the rate of return of your Registered DC Plan. The monthly allocation should be assumed to be made at the end of each month.

If you retire or if your employment with Molson terminates for any other reason than termination for cause, you shall be entitled to receive the notional balance of your Supplemental Account within 60 days after your retirement or termination date.

If you die prior to receiving any benefit under the DC SERP, your beneficiary, as defined under the Registered Plan, shall be entitled to receive the notional balance of your Supplemental

For greater certainty, the amount payable under the DC SERP shall not include any tax adjustment or gross-up.

Molson shall provide you with an annual statement providing information on your Supplemental Account, including activity during the calendar year preceding the date of issuance of such statement, notional allocations made pursuant to paragraph 5 hereof and notional investment income allocated in accordance with paragraph 7 hereof.
