Notice of Grant to Gregg A. Lowe, dated September 27, 2017

The amount payable to you pursuant to your Performance Units will be determined as the result of A x B x C x D, where:

For purposes of the foregoing, your “Target Award Level” is one hundred forty percent (140%) of your Base Salary.

In connection with the Committee’s determination of the annual revenue and non-GAAP operating income results for the Performance Period, the Committee shall (without limiting its authority to apply negative discretion as provided above) make adjustments that eliminate the effect of any changes or events (each a “Change”) that occur during such Performance Period and that were not fully anticipated and/or accurately incorporated into the financial calculations when the performance targets were determined, where (a) making the adjustment will improve performance results, and (b) the Change has a material effect on results under a performance target (determined consistently with past practice), and (c) the Change comes within one or more of the following categories (determined consistently with past practice, to the extent applicable): (1) changes in corporate or capital structure, including but not limited to debt or equity offerings, mergers, acquisitions or divestitures; or (2) other unusual or nonrecurring events.

If prior to settlement of your Performance Units, the Company terminates your employment on account of your LTD Disability or you die, you or your beneficiary will receive payment under your Performance Units as otherwise determined in accordance with this Notice of Grant as if you had remained employed through the payment date for your Performance Units. However, in such event your Base Salary will be proportionally reduced based on the number of calendar days you were employed by the Company and not otherwise on leave of absence as provided above during the Performance Period.

In general, payment under your Performance Units will be made as soon as practicable after the end of the Performance Period and, in any event, will be made no later than (i) the end of the second fiscal quarter following the end of the Performance Period or, if earlier, (ii) the 15th day of the third month after the later of the end of the Company's tax year in which the Performance Period ends or the end of your tax year in which the Performance Period ends. However, if payment becomes due under your Performance Units on account of your death or LTD Disability, payment will be made no later than the 15th day of the third month after the later of the end of the Company’s tax year in which your death or LTD Disability, as applicable, occurs or the end of your tax year in which your death or termination of your employment on account of LTD Disability, as applicable, occurs. Alternatively, in the event a Change in Control occurs prior to the payment date of your Performance Units, any payment that becomes due under your Performance Units will be made no later than the 15th day of the third month after the later of the end of the Company’s tax year in which the Change of Control occurs or the end of your tax year in which the Change of Control occurs.

This award is intended to fulfill any and all agreements, obligations or promises, whether legally binding or not, previously made by the Company or any Employer under the Plan to grant you Performance Units or to provide you annual incentive compensation for the Performance Period. By signing below, you accept such award, along with all prior awards received by you, in full satisfaction of any such agreement, obligation or promise. By signing below, you expressly acknowledge that you are not a participant in or entitled to a payment under the Management Incentive Compensation Plan.
