Exhibit 10.48

NONQUALIFIED STOCK OPTION AGREEMENT
UNDER THE NEUSTAR, INC. 2009 STOCK INCENTIVE PLAN

     This STOCK OPTION AGREEMENT is entered into as of [__________] (the “Grant Date”), between NEUSTAR, INC. (the “Company”) and [_________] (“you”).

1. Option Grant. The Company grants you an option (the “Option”) to purchase up to [_____] shares of the Company’s Common Stock at a price of $[____] per share. The Option is not exercisable now but becomes exercisable in installments, which are cumulative, so that, so long as you do not experience a Termination prior to any such date, the number of shares originally subject to the Option shall vest and become exercisable on each of the dates set forth in Section 5 below.

2. The Plan. The Option is subject to the terms of the Company’s 2009 Stock Incentive Plan (the “Plan”). Capitalized terms used but not defined in this Agreement have the meanings set forth in the Plan.

3. Type of Option. The Option is a nonqualified option, not an incentive stock option, for U.S. tax purposes.

4. Termination. The Option terminates on the seventh (7^th) anniversary of the date of this Agreement, except in the event of your Termination or as otherwise provided in the Plan. The Option will immediately terminate upon your Termination, except that (i) if the Termination is because of your death or Disability, the portion of the Option that is vested and unexercised as of the date of Termination (the “Vested Portion”) will remain exercisable for one year following Termination, and (ii) if the Termination is for any other reason, excluding Cause (or a voluntary termination by you following an event that constitutes Cause), the Vested Portion will remain exercisable for 90 days after Termination, although in all cases the Option will never be exercisable after the seventh (7^th) anniversary of this Agreement. Upon Termination for Cause (or a voluntary termination by you following an event that constitutes Cause), the entire Option (including any Vested Portion) terminates immediately. You will not be deemed to have experienced a Termination until you no longer serve as any of (i) an employee of, or consultant to, the Company or its Affiliates, or (ii) a Director.

Notwithstanding the foregoing, in the event of a Change in Control, subject to the terms of the Plan, if the Option is not assumed or continued or substituted for a substantially equivalent right by the surviving corporation, the successor corporation or its parent corporation, as applicable (the “Successor Corporation”), you shall fully vest in and have the right to exercise the Option as to all shares of Common Stock then subject thereto, including shares as to which the Option would not otherwise be vested or exercisable. Any Options that are assumed or replaced (and any Option shall be considered assumed if the Successor Corporation in a Change in Control reaffirms the Option) in connection with a Change in Control and have not otherwise vested shall immediately vest in full if you experience a Termination (other than by the Company for Cause or by you without Good Reason (as defined below)) within two (2) years after the Change in Control.

For purposes of this Agreement, “Good Reason” shall mean, without your prior written consent, any of the following events or conditions and the failure of the Successor Corporation to cure such event or condition within thirty (30) days after receipt of written notice from you, provided that you serve notice of such event or condition and intended termination within sixty (60) days of its occurrence: (i) a reduction in your annual base salary, except pursuant to a policy generally applicable to employees at your level and above resulting in a reduction of 10% or less; (ii) the Successor Corporation’s failure to cover you under employee benefit plans, programs and practices that, in the aggregate, provide substantially comparable benefits (from an economic perspective) to you relative to the benefits and total costs under the material employee benefit plans, programs and practices in which you (and/or your family or dependents) are participating immediately preceding the Change in Control; (iii) the Successor Corporation’s requiring you to be based at any office location that is more than fifty (50) miles further from your office location immediately prior to a Change in Control, except for reasonable required travel for the Successor Corporation’s business that is not materially greater than such travel requirements prior to such Change in Control; or (iv) a material breach by the Successor Corporation of its obligations to you under the Plan.

5. Vesting Schedule. Subject to Section 4, vesting occurs in increments of whole shares only pursuant to the below schedule, with fractional shares accumulated for distribution in the last installment or such earlier time that they constitute a whole share.

Date on Which Installment Vests		Percentage of Shares in
and Becomes Exercisable		Installment
[First Vesting Date]			25	%
[Second Vesting Date] and the last day of			2.08333	%
each of the succeeding 35 months

6. Exercise. You may exercise the Option by delivering to the Company your signed, written notice of the number of shares to be purchased by your exercise, together with the full purchase price, or by any other method the Committee has approved. Payment may be made by certified check, bank draft or money order payable to the order of the Company or in such other manner as may be acceptable to the Committee. You shall be obligated to pay or make other arrangements to provide for any applicable withholding taxes in a manner acceptable to the Committee.

7. Transfer Restriction. Unless otherwise permitted by the Committee, the Option is non-transferable, except that in the event of your death, it may be transferred by will or the laws of descent and distribution. Only you (or your guardian or legal representative) may exercise the Option.

8. 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 A. In the event that you engage in Detrimental Activity prior to any exercise of Options, such Options shall thereupon terminate and expire. In the event you engage in Detrimental Activity following the exercise of any Option, the Company shall be entitled to recover from you an amount equal to any gain realized as a result of the exercise (whether at the time of exercise or thereafter).

9. No Right to Continued Service. The issuance of this Option does not constitute an agreement by the Company to continue to employ you or retain your services during the entire, or any portion of, the period prior to full vesting of the Option or otherwise.

10. 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).

11. Notice. Any notice or communication to the Company concerning the Option 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, 21575 Ridgetop Circle, Sterling, VA 20166.

You will not have any rights with respect to your Option award unless and until you deliver an executed copy of this Agreement to the Company within 60 days of the Grant Date.
