ARTICLE VIII: CODE SECTION 409A

8.1       The Plan is intended to comply with the requirements of Code Section 409A and shall be interpreted and administered in accordance with that intent.  If any provision of the Plan would otherwise conflict with or frustrate this intent, that provision will be interpreted and deemed amended so as to avoid the conflict.  The nature of any such amendment shall be determined by the Board.  Notwithstanding the above, if the Participant qualifies as a “specified employee,” as defined in Treas. Reg. Section 1.409A-1(i), incurs a Termination Event for any reason other than death and becomes entitled to a distribution under the Plan, then, to the extent required to avoid taxes and penalties under Code Section 409A, no distribution otherwise payable to the Participant during the first six (6) months after the date of such Termination Event shall be paid to the Participant until the date which is one day after the date which is six (6) months after the date of such Termination Event (or, if

earlier, the date of the Participant’s death).  Wherever the Plan indicates that payments will be made within a specified time period, the period during within such time that payments will be made will be determined by the Company in its sole discretion.

8.2       Notwithstanding anything to the contrary in the Plan, neither the Company, any affiliate of the Company, the Board nor the Committee will have any obligation to take any action to prevent the assessment of any excise tax or penalty on any Participant under Code Section 409A and neither the Company, any affiliate of the Company, the Board nor the Committee will have any liability to any Participant for such tax or penalty.

ARTICLE IX: COMPANY’S RIGHT TO TERMINATE

9.1.1 Partial Termination.  The Board may partially terminate the Plan by instructing the Committee not to accept any additional Deferred Compensation Agreements.  If such a partial termination occurs, the Plan shall continue to operate and be effective with regard to Deferred Compensation Agreements entered into prior to the effective date of such partial termination.

9.1.2 Complete Termination. The Board may completely terminate the Plan by instructing the Committee not to accept any additional Deferred Compensation Agreements, and by terminating all Deferred Compensation Agreements.  In the event of complete termination, the Plan shall cease to operate and Company shall pay out each Account and convert all Deferred Share Units into Common Shares.  Payment of an Account shall be made in accordance with the plan termination rules set forth in Code Section 409A, including any such rules that apply if the termination of the Plan is subsequent to a “change in control event” as defined under Code Section 409A.

ARTICLE X: MISCELLANEOUS

10.1.    The right of a Participant or his or her designated Beneficiary to receive a distribution hereunder shall be an unsecured claim against the general assets of the Company, and neither the Participant nor a designated Beneficiary shall have any rights in or against any specific assets of the Company.  Notwithstanding the previous sentence, the Company reserves the right to establish a grantor trust, the assets of which shall remain subject to claims of creditors of the Company, to which Company assets may be invested to fund some or all of the liabilities represented by this Plan.  This Plan shall not be construed to require the Company to fund, prior to payment, any of the Benefits payable under this Plan.

10.2.    If the Committee determines in its sole discretion that a Participant or Beneficiary for any reason is unable to handle properly any property distributable to him or her under the Plan, then the Committee may make such arrangements which it determines to be beneficial to such Participant or Beneficiary, to the extent such arrangements have not been made by

such Participant or Beneficiary, for the distribution of such property, including (without limitation) the distribution of such property to the guardian, conservator, spouse or dependent(s) of such Participant or Beneficiary.

10.3.    The right of any Participant, any Beneficiary, or any other person to the payment of any Benefits under this Plan shall not be assigned, transferred, pledged or encumbered.

10.4.    This Plan shall be binding upon and inure to the benefit of the Company, its successors and assigns and the Participant and his or her heirs, executors, administrators and legal representatives.

10.5.    Nothing contained herein shall be construed as conferring upon any Participant the right to continue in the service of the Company as a director of the Company.

10.6.    If the Company, the Participant, any Beneficiary, or a successor in interest to any of the foregoing, brings legal action to enforce any of the provisions of this Plan, the prevailing party in such legal action shall be reimbursed by the other party for the prevailing party’s costs of such legal action including, without limitation, reasonable fees of attorneys, accountants and similar advisors and expert witnesses.

10.7.    This Plan shall be construed in accordance with and governed by the laws of the state of Maryland, without reference to the principles of conflicts of law thereof, to the extent such construction is not pre-empted by any applicable federal law.
