(c) Delivery – Terminations. Except as otherwise set forth in Section 4(b) or 4(d), in the event the Participant’s Employment with the Company and its Affiliates is terminated for any reason, the Company shall (i) within a reasonable time of such termination, deliver Common Shares to the Participant in respect of the Vested Deferred Units as of such date that are not Retention Units (if any), and (ii) deliver Common Shares to the Participant in respect of the Retention Units in accordance with the delivery schedule set forth in Section 4(a), until the corresponding Holdback Delivery Date(s), at which point the remaining Retention Units shall be delivered to the Participant.

6. Distributions. If on any date while vested or unvested Deferred Units are outstanding hereunder any cash distributions shall be paid on the Common Shares, the Participant shall be entitled to receive, as of such distribution date, a cash payment equal to the product of (a) the number of Deferred Units, if any, held by the Participant as of the related distribution date, multiplied by (b) the per Common Share amount of such cash distribution; provided, however, that the Company shall not be required to pay such distributions (and the Participant shall have no right to such distributions) with respect to any unvested Deferred Units if the Participant has provided or received notice of pending termination of Employment on or prior to such distribution date.

11. Transferability. Unless otherwise determined or approved by the Administrator, no Deferred Units or Retention Units may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Participant other than by will or by the laws of descent and distribution, and any purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance not permitted by this Section 11 shall be void and unenforceable against the Company or any Affiliate.

Without limiting the foregoing, the Administrator may, from time to time, permit the Participant to make arrangements prior to any vesting date or delivery date described herein to pay the applicable withholding taxes by remitting a check prior to the applicable vesting or delivery date.

14. Choice of Law. The interpretation, performance and enforcement of this Award Agreement shall be governed by the law of the State of New York.

15. Subject to Plan. By entering into this Award Agreement, the Participant agrees and acknowledges that the Participant has received and read a copy of the Plan. All Deferred Units, Retention Units and Common Shares issued or transferred with respect thereof are subject to the Plan. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

16. Nature of Grant. By accepting the Deferred Units, the Participant acknowledges, understands and agrees that:

(a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time;

(b) the grant of Deferred Units is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of Deferred Units or benefits in lieu of Deferred Units, even if Deferred Units have been granted in the past;

8

(c) all decisions with respect to future Deferred Units or other grants, if any, will be at the sole discretion of the Company;

(d) the Participant is voluntarily participating in the Plan;

(e) the Deferred Units and the underlying Common Shares, and the income from and value of same, are not intended to replace any pension rights or compensation;

(f) unless otherwise agreed with the Company, the Deferred Units and the underlying Common Shares, and the income from and value of same, are not granted as consideration for, or in connection with, the service the Participant may provide as a director of any affiliate of the Company;

(g) the Deferred Units and the underlying Common Shares, and the income from and value of same, are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, indemnification, pension or retirement or welfare benefits or similar payments, benefits or rights of any kind, and in no event should be considered as compensation for, or relating in any way to, past services for the Company, the Employer or any other Affiliate;

(h) the future value of the underlying Common Shares is unknown, indeterminable and cannot be predicted with certainty;

(i) no claim or entitlement to compensation or damages shall arise from the forfeiture of the Deferred Units resulting from the Participant’s termination of Employment (for any reason whatsoever, whether or not later found to be invalid or in breach of employment or other laws in the jurisdiction where the Participant is employed or otherwise rendering services, or the terms of his or her employment or service agreement, if any); and

(j) for purposes of the Deferred Units, the Participant’s Employment will be considered terminated (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or otherwise rendering services or the terms of his or her employment or service agreement, if any) as of the date that is the earlier of (i) the date he or she is no longer actively providing services to the Company or an Affiliate or (ii) the date he or she receives notice of termination of Employment from the Company or Affiliate, and unless otherwise expressly provided in this Award Agreement or determined by the Company, the Participant’s right to vest in the Deferred Units under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., the Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is employed or otherwise rendering services, or the terms of his or her employment or service agreement, if any). The Administrator will have exclusive discretion to determine when the Participant is no longer actively providing services for purposes of the Deferred Units.
