Schedule D – Deferred Compensation
Summary

PATHEON PHARMACEUTICAL SERVICES INC.
- DEFERRED COMPENSATION PLAN 

	 

As a key member of the Patheon management
team, you are eligible to participate in the Patheon US Deferred Compensation Plan. As an eligible employee you can contribute
up to 25% of your annual base salary, and as agreed to by the Company, up to 100% of your annual bonus to your account on a tax-deferred
basis.

The Company will make contributions for
you if you receive a reduced benefit under the Company’s 401(k) plan as a result of your deferral elections under the Plan,
the 401(k) plan contribution limits and the 401(k) plan nondiscrimination rules. Your deferrals are fully vested at all times.

Amounts credited to your account generally
will commence to be paid in the year following your termination of employment. You can elect to receive distributions in a lump
sum or in annual installments over not more than ten years. To the extent permitted by law, you will have limited opportunities
to (i) receive payment of your account prior to termination of employment and (ii) change the form of payment of your account.
The amounts contributed to your account will be credited with earnings, gains and losses based on the performance of the funds
offered under the Company’s 401(k) plan.

Benefits under the Plan are paid out
of the Company’s general assets, which remain available to the Company for any corporate purpose and are subject to the claims
of the Company’s general creditors. The Company may decide to segregate the Plan assets in a trust (the assets of which remain
subject to the claims of the Company’s general creditors). The Company generally has the ability to terminate the Plan at
any time and distribute your account either (i) in accordance with the form of distribution elected by you (commencing at the time
elected by you) or (ii) in a lump sum as soon as practicable after the termination of the Plan.

The Company may at any time in its discretion
alter, amend, discontinue, or terminate its Deferred Compensation Plan and any of its provisions. While the Company would anticipate
providing notice to its employees prior to any such changes, it may do so without prior notice to its employees.
