following circumstances, provided that the Committee treats all payments to similarly situated Participants on a reasonably consistent basis:
(a) Federal Securities Laws or Other Applicable Law. A Payment may be delayed where the Committee reasonably anticipates that the making of the payment will violate federal securities laws or other applicable law; provided that the delayed payment is made at the earliest date at which the Committee reasonably anticipates that the making of the payment will not cause such violation. For purposes of the preceding sentence, the making of a payment that would cause inclusion in gross income or the application of any penalty provision or other provision of the Code is not treated as a violation of applicable law.
(b) Other Events and Conditions. A payment may be delayed upon such other events and conditions as the Internal Revenue Service may prescribe in generally applicable guidance published in the Internal Revenue Bulletin.
6.10 Actual Date of Payment. If calculation of the amount of the payment is not administratively practicable due to events beyond the control of the Participant (or beneficiary), the payment will be treated as made upon the date specified under the Plan if the payment is made during the first calendar year in which the calculation of the amount of the payment is administratively practicable. Notwithstanding the foregoing, payment must be made no later than the latest possible date permitted under Section 409A of the Code. Moreover, notwithstanding any other provision of this Plan to the contrary except Section 6.7, and to the extent permitted by Section 409A of the Code, a payment will be treated as made upon the date specified under the Plan if the payment is made as close as administratively practicable to the relevant payment date specified herein, and in any event within the same calendar year.
