Re: Syniverse Holdings, Inc. Grant of Restricted Stock

Dear                          (the “Grantee”):

Syniverse Holdings, Inc. (the “Company”) is pleased to advise you that, pursuant to the Company’s 2006 Long-Term Equity Incentive Plan (the “Plan”), the Company’s Compensation Committee has granted to you shares of the Company’s Common Stock, par value $0.001 per share, as set forth below (the “Restricted Shares”), subject to the terms and conditions set forth herein. Capitalized terms used herein but not defined herein shall have the meanings ascribed to such terms in the Plan.

1. Issuance of Shares. In consideration of the Grantee’s service as an employee of the Company, the Restricted Shares shall be issued to the Grantee, and, upon payment to the Company by the Grantee of the aggregate par value thereof, which payment shall be made within ten (10) days of the date hereof, shall be fully paid and nonassessable and shall be represented by a certificate or certificates issued in the name of the Grantee and endorsed with an appropriate legend referring to the restrictions hereinafter set forth.

2. 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.

3. Restrictions on Transfer of Shares. The Restricted Shares may not be sold, assigned, transferred, conveyed, pledged, exchanged or otherwise encumbered or disposed of (each, a “Transfer”) by the Grantee, except to the Company or as permitted under the Plan, unless and until they have become nonforfeitable as provided in Section 4 hereof. Any purported encumbrance or disposition in violation of the provisions of this section or the Plan shall be void AB INITIO, and the other party to

any such purported transaction shall not obtain any rights to or interest in the Restricted Shares. As and when permitted by the Plan, the Committee may in its sole discretion waive the restrictions on transferability with respect to all or a portion of the Restricted Shares. Notwithstanding the foregoing, Grantee may not Transfer Restricted Shares which have become nonforfeitable as provided in Section 4 hereof unless such Restricted Shares are registered pursuant to the Securities Act of 1933 (the “Securities Act”), are sold under Rule 144 promulgated under the Securities Act or unless the Company, after consultation with counsel, and its counsel agree with Grantee that such Transfer is not required to be registered under the Securities Act.

4. Forfeiture of Shares. If the Grantee ceases to be an executive of the Company for any reason, any non-vested Restricted Shares shall be forfeited by the Grantee to the Company and the certificate(s) representing the non-vested portion of the Restricted Shares so forfeited shall be canceled.

5. Dividend, Voting and Other Rights. Except as otherwise provided in this Agreement, from and after the Grant Date, the Grantee shall have all of the rights of a stockholder with respect to the Restricted Shares, including the right to vote the Restricted Shares and receive any dividends that may be paid thereto, provided, however, that any additional Common Stock or other securities that the Grantee may become entitled to receive pursuant to a stock dividend, stock split, recapitalization, combination of shares, merger, consolidation, separation or reorganization or any other change in the capital structure of the Company shall be subject to the same risk of forfeiture, certificate delivery provisions and restrictions on transfer as the forfeitable Restricted Shares in respect of which they are issued or transferred and shall become Restricted Shares for the purposes of this Agreement, and provided further that, any dividend paid with respect to unvested Restricted Shares for which an election under Section 83(b) of the Code has not been made (i) constitutes compensation income subject to all applicable tax withholding and (ii) shall be paid on or about the date the such dividend is paid to holders of the Company’s Common Stock generally, but in any event not later than the later of (A) the calendar year in which such dividend is declared and (B) the fifteenth (15th) day of the third month following the date such dividend is declared.

6. Confidentiality, Inventions, Noncompetition and Nonsolicitation.

(a) Obligation to Maintain Confidentiality. You acknowledge that the confidential or proprietary information and data (including trade secrets) of the Company or any of its Subsidiaries obtained by you while employed by in the service of the Company or any of their respective Subsidiaries (including, without limitation, prior to the date of this Agreement) (“Confidential Information”) are the property of the Company or such Subsidiaries, including information concerning acquisition opportunities in or reasonably related to the Company’s business or industry of which you become aware during the period of your employment or service. Therefore, you agree that you will not disclose to any unauthorized person, group or entity or use for your own account any Confidential Information without the Board’s written consent, unless and to the extent that the Confidential Information, (i) becomes generally known to and available for use by the public other than as a result of your acts or omissions to act, (ii) was known to you prior to your employment or service with the Company or any of its Subsidiaries and Affiliates, or (iii) is required to be disclosed pursuant to any applicable law or court order. You shall use reasonable best efforts to deliver to the Company at the time your employment with the Company and its Subsidiaries ceases for any reason, or at any other time the Company may request, all memoranda, notes, plans, records, reports, computer tapes, printouts and software and other documents and data (and copies thereof) relating to the Confidential Information, Work Product (as defined below) or the business of the Company and its Subsidiaries and Affiliates (including, without

2

limitation, all acquisition prospects, lists and contact information) which you may then possess or have under your control, but excluding financial information of the Company relating to your ownership of Option Shares, which information will nonetheless continue to constitute Confidential Information.

(b) Ownership of Property. You acknowledge that all discoveries, concepts, ideas, inventions, innovations, improvements, developments, methods, processes, programs, designs, analyses, drawings, reports, patent applications, copyrightable work and mask work (whether or not including any Confidential Information) and all registrations or applications related thereto, all other proprietary information and all similar or related information (whether or not patentable) that relate to the Company’s or any of its Subsidiaries’ or Affiliates’ actual or anticipated business, research and development, or existing or future products or services and that were or are conceived, developed, contributed to, made, or reduced to practice by you (either solely or jointly with others) while employed by or in the service of the Company or any of its Subsidiaries or Affiliates (including, without limitation, prior to the date of this Agreement) (including any of the foregoing that constitutes any proprietary information or records) (“Work Product”) belong to the Company or such Subsidiary or Affiliate and you hereby assign, and agree to assign, all of the above Work Product to the Company or to such Subsidiary or Affiliate. Any copyrightable work prepared in whole or in part by you in the course of your work for any of the foregoing entities shall be deemed a “work made for hire” under the copyright laws, and the Company or such Subsidiary or Affiliate shall own all rights therein. To the extent that any such copyrightable work is not a “work made for hire,” you hereby assign and agree to assign to the Company or such Subsidiary or Affiliate all right, title, and interest, including without limitation, copyright in and to such copyrightable work. You shall as promptly as practicable under the circumstances disclose such Work Product and copyrightable work to the Board and perform all actions reasonably requested by the Board (whether during or after your employment with or service to the Company and its Subsidiaries) to establish and confirm the Company’s or such Subsidiary’s or Affiliate’s ownership (including, without limitation, assignments, consents, powers of attorney, and other instruments).

(c) Third Party Information. You understand that the Company and its Subsidiaries and Affiliates will receive from third parties confidential or proprietary information (“Third Party Information”) subject to a duty on the Company’s and its Subsidiaries and Affiliates’ part to maintain the confidentiality of such information and to use it only for certain limited purposes. During the period of your employment with or service to the Company and its Subsidiaries and thereafter, and without in any way limiting the provisions of Section 6(a) above, you will hold Third Party Information in the strictest confidence and will not disclose to anyone (other than personnel and consultants of the Company or its Subsidiaries and Affiliates who need to know such information in connection with their work for the Company or its Subsidiaries and Affiliates) or use, except in connection with your work for the Company or its Subsidiaries and Affiliates, Third Party Information unless expressly authorized by a member of the Board in writing or unless and to the extent that the Third Party Information, (i) becomes generally known to and available for use by the public other than as a result of your acts or omissions to act, (ii) was known to you prior to your employment with or service to the Company or any of its Subsidiaries and Affiliates, or (iii) is required to be disclosed pursuant to any applicable law or court order.

(d) Use of Information of Prior Employers. During your employment or service, you will not improperly use or disclose any confidential information or trade secrets, if any, of any former employers or any other person to whom you have an obligation of confidentiality, and will not bring onto the premises of the Company, its Subsidiaries or Affiliates any unpublished documents or any property belonging to any former employer or any other person to whom you have an obligation of

3

confidentiality unless consented to in writing by the former employer or person. You will use in the performance of your duties only information which is (i)(x) common knowledge in the industry or (y) is otherwise legally in the public domain, (ii) is otherwise provided or developed by the Company, its Subsidiaries or Affiliates or (iii) in the case of materials, property or information belonging to any former employer or other person to whom you have an obligation of confidentiality, approved for such use in writing by such former employer or person.

(e) Noncompetition and Nonsolicitation. You acknowledge that in the course of your employment you will become familiar with the Company’s or its Subsidiaries’ trade secrets and with other confidential information concerning the Company or its Subsidiaries and that your services will be of special, unique and extraordinary value to the Company or its Subsidiaries. Therefore, you agree that:

(i) Noncompetition. While employed by the Company or its Subsidiaries, and (i) in the event of the termination of your employment without Cause, for a period of up to one year thereafter, the exact period to be determined by the Company at the time of termination, or (ii) in the event of the termination of your employment for any other reason, for a period of two years thereafter (the “Noncompete Period”), you shall not, anywhere in the world where the Company or its Subsidiaries conduct or actively propose to conduct business during your employment, directly or indirectly own, manage, control, participate in, consult with, be employed by or in any manner engage in any business competing with the businesses of the Company or its Subsidiaries prior to Termination; provided, however, that you may own up to 2% of any class of an issuer’s publicly traded securities. If your employment is terminated without Cause, as described in subsection (i) above, then commencing on the date of termination and continuing for the duration of the Noncompete Period, the Company shall pay you each month of the Noncompete Period an aggregate amount equal to 1/12^th of your annual base salary in effect as of the date of termination, payable in equal installments on the Company’s regular salary payment dates. Payment of any amounts to you pursuant to this provision shall be reduced or offset by any amounts paid by the Company to you during the same period pursuant to any other agreement you may have with the Company.

(ii) Nonsolicitation. During the Noncompete Period, you shall not directly or indirectly through another entity (i) induce or attempt to induce any employee of the Company or its Subsidiaries to leave the employ of the Company or its Subsidiaries, or in any way interfere with the relationship between the Company or its Subsidiaries and any employee thereof, and (ii) hire any person who was an employee of the Company or its Subsidiaries within 180 days prior to the time such employee was hired by you, (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of the Company or its Subsidiaries to cease doing business with the Company or its Subsidiaries or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and the Company or its Subsidiaries or (iv) directly or indirectly acquire or attempt to acquire an interest in any business relating to the business of the Company or its Subsidiaries and with which the Company, its Subsidiaries or Affiliates has entered into substantive negotiations or has requested and received confidential information relating to the acquisition of such business by the Company, its Subsidiaries or Affiliates in the two-year period immediately preceding a Termination.

4

(iii) Enforcement. If, at the time of enforcement of paragraph 6(e)(i) or (ii), a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum duration, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum duration, scope and area permitted by law. You agree that because your services are unique and you have access to confidential information, money damages would be an inadequate remedy for any breach of paragraph 6. You agree that the Company, its Subsidiaries and Affiliates, in the event of a breach or threatened breach of this paragraph 6, may seek injunctive or other equitable relief in addition to any other remedy available to them in a court of competent jurisdiction without posting bond or other security.

(f) Acknowledgments. You acknowledge that the provisions of this paragraph 6 are (i) in addition to, and not in limitation of, any obligation of yours under the terms of any employment agreement with the Company or a Subsidiary, (ii) in consideration of employment with the Company or its Subsidiaries, (iii) the issuance of the Option by the Company and (iv) additional good and valuable consideration as set forth in this Agreement. In addition, you agree and acknowledge that the restrictions contained in paragraph 6 do not preclude you from earning a livelihood, nor do they unreasonably impose limitations on your ability to earn a living. In addition, you acknowledge (i) that the business of the Company or its Subsidiaries will be international in scope and without geographical limitation, (ii) notwithstanding the state of incorporation or principal office of the Company or its Subsidiaries, or any of their respective executives or employees (including the you), it is expected that the Company or its Subsidiaries will have business activities and have valuable business relationships within its industry throughout the world, and (iii) as part of you responsibilities, you will be traveling and conducting business throughout the world in furtherance of the Company’s business and its relationships. You agree and acknowledge that the potential harm to the Company or its Subsidiaries of the non-enforcement of this paragraph 6 outweighs any potential harm to you of its enforcement by injunction or otherwise. You acknowledge that you has carefully read this Agreement and have given careful consideration to the restraints imposed upon you by this Agreement, and are in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary information of the Company, its Subsidiaries and Affiliates now existing or to be developed in the future. You expressly acknowledge and agree that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical area.

7. Limitation on Rights of Participants. Nothing in this Agreement shall interfere with or limit in any way the right of the Company or its stockholders to terminate your duties as an executive at any time (with or without Cause), nor confer upon you any right to continue as an executive of the Company for any period of time, or to continue your present (or any other) rate of compensation.

8. 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.

9. 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

10. 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.

11. Counterparts. This Agreement may be executed simultaneously in two or more counterparts, each of which shall constitute an original, but all of which taken together shall constitute one and the same Agreement.

12. Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

13. Governing Law. THE VALIDITY, CONSTRUCTION, INTERPRETATION, ADMINISTRATION AND EFFECT OF THE PLAN, AND OF ITS RULES AND REGULATIONS, AND RIGHTS RELATING TO THE PLAN AND TO THIS AGREEMENT, SHALL BE GOVERNED BY THE SUBSTANTIVE LAWS, BUT NOT THE CHOICE OF LAW RULES, OF THE STATE OF DELAWARE.

14. Notices. All notices, demands or other communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally or mailed by certified or registered mail, return receipt requested and postage prepaid, to the recipient.
