During your initial year of employment, your targeted bonus will be prorated based on your start date.

Regular dividends will be paid on these shares throughout the vesting period. You will also be eligible to receive restricted stock awards on an annual basis.

Separation Agreement: In the event your employment is involuntarily terminated, other than for cause, by Bristol-Myers Squibb Company, you will be eligible to receive a severance benefit in an amount equal to one year of your base salary at the rate in effect on the date of your termination (or the amount you would have been entitled to under the Bristol-Myers Squibb Severance Plan, if you were covered under Severance Plan, whichever is greater), provided you timely execute a General Release. If you do not execute a General Release, you will be entitled to basic severance benefits similar to those described in the Bristol- Myers Squibb Company Severance Plan. Although the severance benefits described in this letter are not payable from the Bristol-Myers Squibb Severance Plan, the severance benefits will be paid to you subject to all of the terms and conditions of the Bristol-Myers Squibb Company Severance Plan in effect on the date of termination (including, but not limited to, the terms providing for the eligibility for severance pay, and the determination of which circumstances constitute a termination pursuant to which severance pay would be payable). The enhanced severance payments described above, if selected, will be in lieu of, and not in addition to, the severance (if any) that might be payable to you under the terms of any Bristol-Myers Squibb Company severance plan, if you are eligible for a Bristol-Myers Squibb Company severance plan at the time of your termination.

Change in Control: If you are terminated involuntarily, not for cause, within three years following the effective date of a change in control, a minimum of twelve months of base salary will be provided as severance pay. This twelve-month benefit includes notice periods in which you do not actually work and pay in lieu of notice periods.
