Each year, the date on which the Committee certifies the level of achievement of the prior year’s Performance Goals shall occur no later than March 15 (or, if March 15 is not a business day, the immediately preceding business day).

4. Payment. As soon as practicable following the Vesting Date (or such earlier date of vesting), subject to annual written certification by the Committee of the level of achievement of the respective Performance Goals for each of the Performance Periods, each of your earned PVRSUs, together with Dividend Equivalents (as defined in Section 10) on such PVRSUs earned as of such date (based upon the degree of attainment of the relevant Performance Goals), will be converted to an equal number of shares of Common Stock (provided the threshold level of performance is attained). Subject to the provisions of the Plan and this Agreement, any payment with respect to the Award shall be paid in shares of Common Stock, after the satisfactory payment of applicable withholding taxes as set forth in Section 10, as soon as practicable (but not more than 30 days) following the applicable date of vesting, except as otherwise provided in Section 5(f).

(g) For purposes of this Agreement:

i. “Cause” shall mean, with respect to your termination of employment, the following: (A) your willful and continued failure to attempt in good faith to substantially perform your duties to the Company and/or its Affiliates or your willful refusal to follow the material, lawful directives of the Board or the officer to whom you report, if any (other than any such failure or refusal resulting from your incapacity); (B)

No act or failure to act shall be considered “willful” unless it is done, or omitted to be done, by you without the reasonable belief that your action or omission was in the best interests of the Company. For this purpose, any act or failure to act shall be deemed to be in the best interests of the Company if it is done or omitted to be done based upon authority given pursuant to a resolution duly adopted by the Board, the instructions of the Company’s Chief Executive Officer (if applicable), or the advice of counsel to the Company. Termination of your employment shall not be deemed to be for Cause unless, prior to termination, the Company delivers you copies of resolutions duly adopted by the affirmative vote of not less than a majority of the Board (after reasonable written notice is provided to you and you are given a reasonable opportunity, together with counsel, to be heard before the Board), finding that you have engaged in the conduct described in any of (A)-(E) above.

ii. “Good Reason” shall mean, without your prior written consent, any of the following events or conditions and the failure of the Company to cure such event or condition within thirty (30) days after receipt of written notice from you specifying the events or conditions in reasonable detail, provided that you serve notice of such event and intended termination within sixty (60) days of your knowledge of its occurrence and you terminate your employment within thirty (30) days following the expiration of the applicable cure period: (A) a material diminution in your duties, responsibilities, or authorities; (B) a material reduction in your annual base salary or annual or long-term incentive compensation opportunities; (C) a material reduction in the benefits provided to you and/or your family or dependents, in the aggregate, under the material employee benefit plans, programs and practices of the Company; (D) requiring you to be based at any office location that is more than fifty (50) miles farther from your primary work location, except for reasonable required travel on behalf of the Company; or (E) a material breach by the Company of its obligations to you under this Agreement or under any other material agreement or arrangement between the Company and you, after giving effect to any applicable notice requirements and cure periods set forth therein.

through the Vesting Date with the Company and its Affiliates. The number of shares of Restricted Stock into which your PVRSUs will convert shall be determined as follows:

(a) For Awards in which a Change in Control occurs prior to the end of an annual performance period, the respective PVRSUs will be converted into that number of shares of Restricted Stock equal to the number of shares that would have been payable had the Target level of performance been achieved (i.e., 100% of the Target Award). Any conversion under this Section 6(a) shall be subject to certification by the Committee concurrently with or as soon as practicable following the consummation of the Change in Control; or

(b) For Awards in which a Change in Control occurs on or after the end of an annual performance period and prior to a Vesting Date, the PVRSUs will be converted into shares of Restricted Stock based on the actual level of performance achieved. Any conversion under this Section 6(b) shall be subject to certification by the Committee concurrently with or as soon as practicable following the consummation of the Change in Control.

Your Restricted Stock shall immediately vest in full in the event that the Company, its successor corporation or its parent corporation, as applicable, does not assume your Restricted Stock.

7. Detrimental Activity. For purposes of this Award, Detrimental Activity shall have the meaning set forth in the Plan and additionally shall mean any of the activities set forth on Annex B. In the event that you engage in Detrimental Activity, the Committee may direct that all unvested PVRSUs, unvested Restricted Stock issued pursuant to Section 6, and unvested Dividend Equivalents, together with any PVRSUs and/or Restricted Stock and Dividend Equivalents which have vested but with respect to which Common Stock has not yet been issued and any dividends which have been declared but not yet paid to you, shall be immediately forfeited to the Company, and you shall pay to the Company an amount equal to the Fair Market Value at the time of issuance or delivery of any Common Stock previously delivered or issued to you in respect of the Award.

8. Adjustments. In the case of any change in corporate structure as contemplated under Section 4.2(b) of the Plan, an equitable adjustment shall be deemed necessary and shall be made in accordance with such Section 4.2(b).

9. Restrictions on Transfer. You shall not sell, transfer, pledge, hypothecate, assign or otherwise dispose of (any such action, a “Transfer”) the Award in any manner, except as set forth in the Plan or this Agreement. Any attempted Transfer in violation of the Plan or this Agreement shall be void and of no effect.

10. Rights as a Common Stockholder. You shall have no rights as a stockholder with respect to any shares of Common Stock covered by the PVRSUs until you shall have become the holder of record of such shares, and, except as expressly provided in this Section 10, no adjustment shall be made for dividends or distributions or other rights in respect of such shares for which the record date is prior to the date upon which you shall become the holder of record thereof. Notwithstanding the foregoing, as of each dividend payment date for each cash dividend on the Common Stock covered by a PVRSU, the Company shall award you additional PVRSUs (“Dividend Equivalents”), which shall be subject to the same restrictions and risk of forfeiture, and all other terms and conditions, as the PVRSUs granted pursuant to this Agreement. The number of Dividend Equivalents to be granted shall equal the product of (x) the per-share cash dividend payable with respect to each share of Common Stock, multiplied by (y) the total number of PVRSUs that have not been paid or forfeited as of the record date for such dividend, divided by the Fair Market Value of one share of Common Stock on the payment date of such dividend. In addition, stock dividends on the Common Stock covered by a PVRSU shall be credited to a dividend book entry account on your behalf with respect to each PVRSU, provided that you shall not be entitled to such dividends unless and until the PVRSU vests and is paid.

11. Taxes.

(a) Generally. You will be liable for any and all taxes, including withholding taxes, arising out of this Award, and the Company shall have the right to require, prior to the issuance or delivery of Common Stock, payment of any federal, state or local taxes required by law to be withheld. Prior to the delivery of Common Stock hereunder, you shall pay all required taxes to the Company, which payment may be made in cash or by reducing the number of shares of Common Stock otherwise deliverable under the Award, subject to the Company’s policies then in effect, unless the Company has established alternative procedures for such payment. For the avoidance of doubt, in the event that the Retirement provisions set forth herein results in a taxable event to you prior to the date of settlement of the Award, then any federal, state and local income, employment and other taxes required to be withheld by the Company in connection with such taxable event, shall be effectuated by withholding delivery of a number of shares of Common Stock having a Fair Market Value as of the date of settlement equal to an amount no greater than the minimum statutory tax withholding requirements unless the Company has established alternative procedures for such payment.

(b) Section 409A of the Code. This Agreement and the Award are intended to comply with or be exempt from the applicable requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and shall be limited, construed and interpreted in a manner so as to comply therewith, and for the avoidance of doubt, subject to the provisions of Section 14.14 of the Plan (Section 409A of the Code).

(c) Section 280G/4999 of the Code. Notwithstanding anything set forth herein to the contrary, if any payment or benefit you would receive from the Company pursuant to this Agreement or otherwise (“Payment”) would constitute a “parachute payment” within the meaning of Section 280G of the Code and, but for this Section 11(c), would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the amounts constituting Payments which would otherwise be payable to you or for your benefit shall be reduced to the extent necessary to the Revised Amount.  The “Revised Amount” shall be either (x) or (y), whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes and the Excise Tax (all computed at the highest applicable marginal rate), results in your receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the payment may be subject to the Excise Tax and where: (x) is the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax and (y) is the full, unreduced, total Payment.  If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment is reduced to the amount in clause (x) above, unless to the extent permitted by Code Sections 280G and 409A you designate another order, the reduction shall occur in the following order: (i) cash payments shall be reduced next and in reverse chronological order such that the cash payment owed on the latest date following the occurrence of the event triggering such excise tax will be the first cash payment to be reduced; (ii) accelerated vesting of equity awards shall be cancelled/reduced first and in the reverse order of the date of grant for such equity awards (i.e., the vesting of the most recently granted stock awards will be reduced first), with full-value awards reversed before any stock option or stock appreciation rights are reduced; and (iii) employee benefits shall be reduced last and in reverse chronological order such that the benefit owed on the latest date following the occurrence of the event triggering such excise tax will be the first benefit to be reduced.  Except as set forth in the next sentence, all determinations to be made under this Section 11(c) shall be made by a nationally recognized United States public accounting firm selected by the Company, which accounting firm shall provide its determinations and any supporting calculations and documentation to you and the Company promptly after the change in ownership or effective control of the Company or ownership of a substantial portion of the Company’s assets (within the meaning of Code Section 280G).  Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon you and the Company.  In making its determination, the accounting firm shall take into account (if applicable) the value of any non-competition covenant or similar restrictive covenant to which you are a party, whether set forth herein or in any severance plan or policy or individual agreement or otherwise.  The costs and expenses of the accounting firm shall be borne by the Company.

12. Severability. The provisions of this Award and the Plan are intended to be severable, and any illegal or invalid term shall not affect the validity or legality of the remaining terms.

13. Not an Employment Agreement. The issuance of this Award does not constitute an agreement by the Company to continue to employ you during the entire, or any portion of, the vesting and/or performance periods of the Award or otherwise.

14. Notice. Any notice or communication to the Company concerning the PVRSUs must be in writing and delivered in person, or by U.S. mail, to the following address (or another address specified by the Company): Neustar, Inc., Attn: General Counsel, 00000 Xxxxxxxx Xxxxxx, Xxxxxxxx, XX 00000.
