Dear Mr. Carter:

Inteliquent, Inc. (the “Company”) is pleased to advise you that, pursuant to the Company’s Amended and Restated 2007 Equity Incentive Plan (the “Plan”), the Company’s Board of Directors has approved the issuance of shares of the Company’s Common Stock, par value $0.001 per share, to you as set forth below (the “Restricted Shares”), subject to the terms and conditions set forth herein. Upon payment to the Company by you of the aggregate par value thereof, which payment shall be made promptly after the date hereof, the Restricted Shares shall be fully paid and nonassessable. Capitalized terms used herein but not defined herein shall have the meanings ascribed to such terms in the Plan.

Notwithstanding the vesting dates set forth above, if (1) a Change in Control (as defined in your employment agreement with the Company) occurs and your employment is not terminated, 50% of any unvested Restricted Shares will vest upon the Change in Control or (2) your employment is terminated without Cause (as defined in your employment agreement with the Company) or by

you for Good Reason (as defined in your employment agreement) and not in connection with a Change in Control, any unvested Restricted Shares that would have vested within six months of the date of termination will become fully vested. In the event your employment is terminated by the Company without Cause (as defined in your employment agreement) within twelve (12) months following or one (1) month prior to a Change of Control, 100% of any unvested Restricted Shares will vest upon termination.

1. Conformity with Plan. The grant of Restricted Shares is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan (which is incorporated herein by reference). Inconsistencies between this Agreement and the Plan shall be resolved in accordance with the terms of the Plan. By executing and returning the enclosed copy of this Agreement, you acknowledge your receipt of this Agreement and the Plan and agree to be bound by all of the terms of this Agreement and the Plan. Notwithstanding the foregoing, (a) you will not be considered to have engaged in “Competition” as defined in the Plan unless you have breached the provisions of Section 4.2 of your employment agreement, and (b) the determination of whether you have engaged in Competition, or the reason for the termination of your employment, shall be determined in accordance with the provisions of your employment agreement.

2. Rights of Participants. Nothing in the Agreement or in any grant thereunder shall confer any right on a participant to continue in the service or employ as a director or officer of or in the performance of services for the Company or a Subsidiary or shall interfere in any way with the right of the Company or a Subsidiary to terminate the employment or performance of services or to reduce the compensation or responsibilities of a participant at any time.

3. Remedies. The parties hereto shall be entitled to enforce their rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto acknowledge and agree that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and that any party hereto may, in its sole discretion, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief (without posting bond or other security) in order to enforce or prevent any violation of the provisions of this Agreement.

4. Successors and Assigns. Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and permitted assigns of the parties hereto whether so expressed or not.

5. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement.

6. Counterparts. This Agreement may be executed in counterparts, each of which shall constitute an original, but all of which taken together shall constitute one and the same Agreement. Signatures exchanged electronically (such as a PDF) will be treated for all purposes as original signatures.
