Exhibit 10.1

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (the “Agreement”) is entered into as of March 19, 2015, among Syniverse Corporation, a Delaware corporation (“Syniverse” and, together with any Subsidiaries and Affiliates as may employ Executive from time to time, and any successor(s) thereto, the “Company”) and Robert Reich (“Executive”).

WHEREAS, the services of Executive and his managerial and professional experience are of value to the Company;

WHEREAS, the Company desires to employ Executive as its Executive Vice President and Chief Financial Officer upon the terms and conditions set forth herein.

NOW THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Employment. The Company shall employ Executive, and Executive hereby accepts employment with the Company, upon the terms and conditions set forth in this Agreement. The initial term of employment under this Agreement (the “Initial Term”) shall be for the period beginning on April 1, 2015 (the “Start Date”) and ending on the third (3^rd) anniversary thereof, unless earlier terminated as provided in Section 4. The employment term hereunder shall be automatically renewed for successive one-year periods (each an “Extension Term” and together with the Initial Term, the “Employment Period”), unless either party hereto gives written notice of non-renewal to the other no later than ninety (90) days prior to the expiration of the Initial Term or any Extension Term, as applicable.

2. Position and Duties.

(a) During the Employment Period, Executive shall serve as Executive Vice President and Chief Financial Officer of the Company, and shall have the normal duties, responsibilities, functions and authority of such position, subject to the power and authority of the Board of Directors of Syniverse (the “Board”) and the Company’s Chief Executive Officer to expand or limit such duties, responsibilities, functions and authority and the power and authority of the Board (and the boards of directors of any Subsidiaries or Affiliates of Syniverse that may employ Executive from time to time, as applicable) to overrule actions of officers of the Company; provided that such permitted limitations may, nevertheless, constitute “Good Reason” under Section 8. During the Employment Period, Executive shall render such administrative, financial and other executive and managerial services to the Company and its Affiliates which are consistent with Executive’s position (including service as an officer or director of any such Affiliate) as the Board may from time to time direct.

(b) During the Employment Period, Executive shall report to the Chief Executive Officer of the Company and shall devote his best efforts and his full business time and attention (except for permitted vacation periods and reasonable periods of illness or other incapacity) to the business and affairs of the Company and its Affiliates. Executive shall perform his duties, responsibilities and functions to the Company and its Affiliates hereunder to the best of his abilities in a diligent, trustworthy, professional and efficient manner and shall comply with the

Company’s and its Affiliates’ policies and procedures in all material respects. In performing his duties and exercising his authority under the Agreement, Executive shall develop, support and implement the business and strategic plans approved from time to time by the Board. During the Employment Period, Executive shall not accept other employment, serve as an officer or director of, or otherwise perform services for compensation for, any other entity without the prior written consent of the Board; provided that Executive may serve as an officer or director of or otherwise participate in purely educational, welfare, social, religious and civic organizations so long as such activities do not interfere with Executive’s employment hereunder. The Company and Executive agree that during the Employment Period Executive’s principal location of employment with the Company shall be at the Company’s headquarters in Tampa, Florida.

3. Compensation and Benefits.

(a) During the Employment Period, Executive’s base salary shall be Four Hundred Thousand Dollars ($400,000) per annum (as increased from time to time as provided below, the “Base Salary”), which salary shall be payable by the Company in regular installments in accordance with the Company’s general payroll practices (in effect from time to time). The Board or the Compensation Committee thereof (either such entity, the “Compensation Committee”) shall review the Base Salary each year during the Employment Period, and Executive may receive increases (but no decreases) in his Base Salary from time to time, based upon his performance, subject to approval of the Compensation Committee. In addition, during the Employment Period, Executive shall be entitled to participate in the Company’s employee benefit programs for which other senior executive employees of the Company are generally eligible. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time.

(b) In addition to Base Salary, Executive will have an opportunity to earn a cash bonus (the “Annual Bonus”) each calendar year ending during the Employment Period, commencing with calendar year 2015, as determined by the Compensation Committee, with a target annual bonus equal to seventy-five percent (75%) of Executive’s Base Salary (the “Target Bonus”) and a maximum annual bonus equal to one-hundred fifty percent (150%) of Executive’s Base Salary with respect to each calendar year during the Employment Period, based upon the achievement with respect to any calendar year of performance objectives as approved by the Compensation Committee (the “Bonus Objectives”). The Bonus Objectives will be financial and/or other objective targets that the Compensation Committee reasonably believes are reasonably attainable at the time that they are set. Such bonus amounts, if any, shall be payable within 100 days following the end of each calendar year at such time as other executive officer bonuses are paid and, except as otherwise provided in Section 4, so long as Executive remains in the employ of the Company on December 31 of such calendar year.

(c) Equity Awards.

(i) On the Start Date, Syniverse shall grant Executive an option (the “Option”) to purchase 500,000 shares of common stock of Syniverse, par value $0.01 (“Common Stock”), under the 2011 Equity Plan of Syniverse Corporation, as it may be amended from time to time (the “2011 Equity Plan”), and an award agreement thereunder. The exercise price per share subject to the Option shall equal the fair market value of a share of Common Stock on the date of grant, which, as of the date hereof, equals $11.25.

2

(ii) Notwithstanding anything to the contrary in this Agreement or any award agreement with respect to the Option, subject to Executive’s continued employment for the period beginning on the Start Date and ending on the date of the consummation of a Change in Control, any equity awards (including, without limitation, the Option) granted to Executive under the 2011 Equity Plan (or any successor thereto) that have not otherwise vested prior to such Change in Control shall become vested immediately prior to such Change in Control (and subject to the consummation of such Change in Control).

(iii) Executive may, upon written notice to Syniverse on or prior to the Start Date, elect to purchase up to 50,000 shares of Common Stock from Syniverse at the fair market value of such shares on the date of purchase which, as of the date hereof, equals $11.25. Such purchase shall be consummated within thirty (30) days following the Start Date and the purchased shares shall be subject to the terms of the 2011 Equity Plan and a stock purchase agreement thereunder and the Management Stockholders Agreement of Syniverse Corporation, dated as of April 6, 2011, by and among Syniverse, certain Investors, and certain individual stockholders who are party thereto, as amended.

(d) During the Employment Period, the Company shall reimburse Executive for all reasonable business expenses incurred by him in the course of performing his duties and responsibilities under this Agreement which are consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company’s requirements with respect to reporting and documentation of such expenses.

(e) The Company shall reimburse Executive for all reasonable, documented, out-of-pocket Relocation Costs incurred by Executive in connection with Executive’s relocation from Honolulu, Hawaii to Tampa, Florida, up to an aggregate amount equal to $10,000.

(f) All amounts payable to Executive as compensation hereunder, including, without limitation, any equity awards issued to Executive, shall be subject to all required and customary withholding by the Company as provided in Section 18 herein.

4. Termination. Subject to Section 25:

(a) Executive’s employment with the Company may be terminated for Cause at any time by resolution approved by no less than a majority of the members of the Board; provided that, to the extent the underlying reasons for Cause are curable, as determined by the Board in its good faith discretion, no termination for Cause shall be treated as such until the 30th day following the date on which the Company has provided notice to Executive of the Board’s decision to terminate Executive for Cause (such notice to include reasons for the Board’s decision) and within such 30-day period Executive is provided a reasonable opportunity to address the Board and to cure the underlying reasons for the Cause termination; provided, further, that the Company reserves the right to require that Executive not report to work or otherwise perform any duties during such 30-day period. Upon such a termination, the Company shall have no obligation to Executive other than the payment of Executive’s earned and unpaid compensation to the effective date of such termination and as provided in Section 4(g).

3

(b) If during the Employment Period, Executive shall become ill, mentally or physically disabled, or otherwise incapacitated so as to be unable regularly to perform the duties of his position for a period in excess of ninety (90) consecutive days or more than one hundred twenty (120) days in any consecutive twelve (12) month period (“Permanent Disability”), then the Company shall have the right to terminate Executive’s employment with the Company upon written notice to Executive. In the event of Executive’s death or in the event the Company terminates Executive’s employment as a result of his Permanent Disability, Executive or Executive’s estate shall be entitled to the benefits that he would have been entitled to receive if Executive’s employment had been terminated by the Company without Cause pursuant to Section 4(d) (subject to the provisos and conditions set forth therein); provided, however, that, except as provided in Sections 4(d) and (g), the Company shall have no other obligation to Executive or Executive’s estate pursuant to this Agreement in the event of Executive’s death or in the event that Executive’s employment with the Company is terminated as a result of his Permanent Disability.

(c) Executive may voluntarily resign from his employment with the Company without Good Reason (including, without limitation, due to Executive’s non-renewal of this Agreement pursuant to Section 1), provided that Executive shall provide the Company with ninety (90) days advance written notice (which notice requirement may be waived, in whole or in part, by the Company in its sole discretion) of his intent to terminate. Upon such a termination, the Company shall have no obligation other than the payment of Executive’s earned but unpaid compensation to the effective date of such termination and as provided in Section 4(g).

(d) Executive’s employment with the Company may be terminated at any time by the Company without Cause. If the Company terminates Executive’s employment without Cause or purportedly for Cause but without complying with the provisions of Section 4(a), the Company shall have the following obligations to Executive (but excluding any other obligation, except as provided in Section 4(g), to Executive pursuant to this Agreement):

(i) The continuation of his Base Salary, as severance, payable in accordance with the Company’s general payroll practices (in effect from time to time) for a period commencing on the date of termination and ending one year from the date of termination;

(ii) Executive shall be entitled to receive any unpaid Annual Bonus for the previous fiscal year and an amount equal to the Target Bonus (i.e., 75% of his current Base Salary) for the then current fiscal year (regardless of Company performance), such unpaid Annual Bonus to be paid at such times as it would be payable if Executive’s employment had not been terminated and such amount equal to the Target Bonus for the then current fiscal year to be paid at such times as the Annual Bonus for the then current fiscal year would be payable had Executive’s employment not terminated;

(iii) If Executive makes a timely election for continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) with respect to the group health plans provided to Executive at the time of such termination (the “Welfare

4

Plans”), the Company shall pay that portion of the COBRA premium that the Company pays for other senior executive employees with the same coverage for the shorter of (A) twelve (12) months and (B) the period that Executive is eligible for COBRA continuation coverage;

(iv) With respect to the Option, notwithstanding anything to the contrary in the award agreement related thereto, if such termination of Executive’s employment occurs during (A) the period beginning on the Start Date and ending on April 1, 2016, twenty percent (20%) of the portion of the Option subject to time vesting (i.e., 15% of the Option) shall automatically become vested and exercisable (to the extent not otherwise then exercisable); (B) the period beginning on April 2, 2016 and ending on April 1, 2017, forty percent (40%) of the portion of the Option subject to time vesting (i.e., 30% of the Option) shall automatically become vested and exercisable (to the extent not otherwise then exercisable); (C) the period beginning on April 2, 2017 and ending on April 1, 2018, sixty percent (60%) of the portion of the Option subject to time vesting (i.e., 45% of the Option) shall automatically become vested and exercisable (to the extent not otherwise then exercisable), (D) the period beginning on April 2, 2018 and ending on April 1, 2019, eighty percent (80%) of the portion of the Option subject to time vesting (i.e., 60% of the Option) shall automatically become vested and exercisable in full (to the extent not otherwise then exercisable), and (E) the period beginning on April 2, 2019 and ending on April 1, 2020, one hundred percent (100%) of the portion of the Option subject to time vesting (i.e., 75% of the Option) shall automatically become vested and exercisable in full. For the avoidance of doubt, the percentage of the Option that will become vested and exercisable pursuant to this Section 4(d)(iv) shall equal the additional percentage of the Option that would have otherwise become vested and exercisable had Executive remained employed by the Company through the vesting date next following the date of termination; and

(v) Notwithstanding anything to the contrary in the award agreements related to the Option, the unvested portion of Option, as of the date of such termination of Executive’s employment (and immediately following any accelerated vesting described in Section 4(d)(iv)) (the “Unvested Option”) shall remain outstanding and not expire until the 181^st day following the date of such termination of Executive’s employment and if and only if such termination occurs within the 180-day period immediately prior to the consummation of a Change in Control, then the Unvested Option that has not otherwise theretofor become vested and exercisable shall automatically become vested and exercisable as of the date of the Change in Control (subject to the consummation of such Change in Control);

provided, however, that the continuation of such salary and benefits and any right to acceleration of vesting and exercisability of the Option shall cease on the occurrence of any circumstance or event that would constitute Cause under Section 8 (including any material breach of the covenants contained in Section 5 or Section 6 below); provided, further, that Executive’s eligibility to participate in the Welfare Plans shall cease at such time as Executive is offered comparable coverage with a subsequent employer. For the avoidance of doubt, Unvested Option shall not, at any time after termination of employment, be eligible for vesting based on the passage of time.

(e) Subject to Section 25(f), Executive’s employment with the Company may be terminated by Executive for Good Reason on thirty (30) days advance written notice to the Company, which notice shall detail the specific basis for such termination. The Company shall

5

be given the opportunity to cure the basis for such termination within such thirty (30) day period. If Executive terminates his employment under this Section 4(e), Executive shall be entitled to receive the same benefits as if his employment had been terminated by the Company without Cause under Section 4(d) (subject to the provisos and conditions set forth therein).

(f) Executive’s employment with the Company may be terminated due to the Company’s non-renewal of the Agreement pursuant to Section 1. In the event the Company terminates Executive’s employment as a result of non-renewal of the Agreement, Executive shall be entitled to the benefits that he would have been entitled to receive if Executive’s employment had been terminated by the Company without Cause pursuant to Section 4(d) (subject to the provisos and conditions set forth therein).

(g) Executive acknowledges that any payments and benefits under this Section 4 resulting from a termination of Executive’s employment with the Company are in lieu of any and all claims that Executive may have against the Company and its Affiliates (other than (i) benefits under the Company’s employee benefit plans that by their terms survive termination of employment, (ii) benefits under COBRA, (iii) rights with respect to unreimbursed business expenses, if any, pursuant to Section 3(d) or 3(e), (iv) rights to indemnification under certain indemnification arrangements for officers of the Company, and (v) rights with respect to indemnification and insurance pursuant to Section 24), and represent liquidated damages (and not a penalty). The Company shall require that Executive execute and not revoke a release of claims, substantially in the form attached hereto as Exhibit A, in accordance with Section 25(c) as a condition to Executive’s receipt of such payments. The Company acknowledges that no such payment shall be reduced by any amount Executive may earn or receive from employment or other source after a Separation and that Executive shall have no obligation to seek other employment or otherwise to mitigate the Company’s payment obligations.

5. Confidential Information.

(a) Obligation to Maintain Confidentiality. Executive acknowledges that the information and data obtained by him during the course of his employment with the Company and/or its Subsidiaries and Affiliates and his performance under this Agreement concerning the business and affairs of the Company and its Subsidiaries and Affiliates, including information concerning acquisition opportunities in or reasonably related to the Company’s and its Subsidiaries’ or Affiliates’ business or industry of which Executive becomes aware during his employment with the Company and/or its Subsidiaries and Affiliates prior to the date hereof and during the Employment Period (collectively, “Confidential Information”), are the property of the Company or such Subsidiaries and Affiliates. Therefore, Executive agrees that he will not disclose to any unauthorized Person or use for his own account any Confidential Information without the Board’s prior written consent. Executive agrees to deliver to the Company at a Separation, or at any other time the Company may request in writing, all memoranda, notes, plans, records, reports and other documents (and copies thereof) relating to the business of the Company and its Subsidiaries and Affiliates (including, without limitation, all acquisition prospects, lists and contact information) which he may then possess or have under his control. Notwithstanding the foregoing, the restrictions contained herein shall not apply to any information which Executive can demonstrate by written record (i) was already available to the public, otherwise than by breach of this Agreement, or (ii) was the subject of a court order for

6

Executive to disclose, provided that Executive shall give the Company prompt notice of any and all such requests for disclosure so that it may take all necessary or desired action to avoid or limit disclosure.

(b) Ownership of Property. Executive acknowledges that all inventions, innovations, improvements, developments, methods, processes, programs, designs, analyses, drawings, reports, 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 are conceived, developed, contributed to, made, or reduced to practice by Executive (either solely or jointly with others) while employed by the Company or any of its Subsidiaries or Affiliates (including any of the foregoing that constitutes any proprietary information or records) (“Work Product”) belong to the Company or such Subsidiary or Affiliate and Executive hereby assigns, and agrees 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 Executive in the course of his 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,” Executive hereby assigns and agrees 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. Executive shall promptly disclose such Work Product and copyrightable work to the Board and perform all actions reasonably requested by the Board (whether during or after the Employment Period) 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. Executive understands 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 Employment Period and thereafter, and without in any way limiting the provisions of Section 5(a) above, Executive will hold Third Party Information in the strictest confidence and will not disclose to anyone (other than personnel of the Company or its Subsidiaries or Affiliates who need to know such information in connection with their work for the Company or its Subsidiaries or Affiliates) or use, except in connection with his work for the Company or its Subsidiaries or Affiliates, Third Party Information unless expressly authorized by a member of the Board in writing or required by applicable law or by judicial, legislative or regulatory process.

(d) Use of Information of Prior Employers. During the Employment Period, Executive will not improperly use or disclose any confidential information or trade secrets, if any, of any former employers or any other Person to whom Executive has an obligation of confidentiality, and will not bring onto the premises of the Company or any of its Subsidiaries or Affiliates any unpublished documents or any property belonging to any former employer or any other Person to whom Executive has an obligation of confidentiality unless consented to in writing by the former employer or Person. Executive will use in the performance of his duties only information which is (i) generally known and used by Persons with training and experience comparable to Executive’s and that is (x) common knowledge in the industry or (y) otherwise

7

legally in the public domain, (ii) otherwise provided or developed by the Company or any of its Subsidiaries or Affiliates or (iii) in the case of materials, property or information belonging to any former employer or other Person to whom Executive has an obligation of confidentiality, approved for such use in writing by such former employer or Person.

6. Non-Compete, Non-Solicitation. Executive acknowledges that in the course of his employment with the Company he will become familiar with the Company’s and its Subsidiaries’ and Affiliates’ trade secrets and with other confidential information concerning the Company and such Subsidiaries and Affiliates and that his services will be of special, unique and extraordinary value to the Company and such Subsidiaries and Affiliates. Therefore, Executive agrees that:

(a) Noncompetition. During the Employment Period and for a period of one year thereafter (the “Noncompete Period”), he shall not, anywhere in the world, directly or indirectly own, manage, control, participate in, consult with, render services for, or in any manner engage in (A) any business relating to the provision of mobile connectivity and interoperability solutions, including roaming data clearinghouse and financial settlement services, SMS and MMS messaging, wireless network and data transport services, revenue assurance services, real-time intelligence tools and mobile engagement solutions, to wireless carriers or enterprises, (B) any other type of business in which the Company or one of its Affiliates is also engaged, or plans to be engaged, so long as Executive is involved in such business or planned business on behalf of the Company or one of its Affiliates, or (C) any business in which the Company or any of its Subsidiaries or Affiliates has entertained discussions or has requested and received information relating to the acquisition of such business by the Company or its Subsidiaries or Affiliates during the six-month period immediately prior to a Separation; provided, however, that Executive may own up to 2% of any class of an issuer’s publicly traded securities.

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

(c) Non-disparagement. During the Employment Period and thereafter, (i) Executive agrees that he shall not make, or cause or assist any other person to make, any statement or other communication to any third party which impugns or attacks, or is otherwise critical of, in any

8

material respect, the reputation, business or character of the Company, any of its Affiliates or any of their respective directors, officers or employees (collectively, “Company Persons”) and (ii) the Company agrees that it shall instruct its officers and directors not to make, or cause or assist any other person to make, any statement or other communication to any third party which impugns or attacks, or is otherwise critical of, in any material respect, the reputation, business or character of Executive; provided that neither party shall be required to make any untruthful statement or to violate any law; and provided, further, that either party may make any truthful statement or communication to any third party which clarifies or corrects any statement or other communication by or on behalf of the other party, or, in the case of the Company, any Company Person, which impugns or attacks, or is otherwise critical of, in any material respect, the reputation, business or character of either party or any Company Person.

(d) Extension of Noncompete Period. The Noncompete Period shall be extended by the length of any period during which Executive is in breach of the terms of this Section 6.

(e) Enforcement. If, at the time of enforcement of Section 5 or this Section 6, 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. Because Executive’s services are unique and because Executive has access to confidential information, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Agreement. Therefore, in the event a breach or threatened breach of this Agreement, the Company, its Subsidiaries or Affiliates or their successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

(f) Additional Acknowledgments. Executive acknowledges that the provisions of this Section 6 are in consideration of (i) employment with the Company and (ii) additional good and valuable consideration as set forth in this Agreement. In addition, Executive agrees and acknowledges that the restrictions contained in Section 5 and this Section 6 do not preclude Executive from earning a livelihood, nor do they unreasonably impose limitations on Executive’s ability to earn a living. In addition, Executive acknowledges (A) that the business of the Company and its Subsidiaries and Affiliates will be international in scope and without geographical limitation, (B) notwithstanding the state of incorporation or principal office of the Company or any of its Subsidiaries or Affiliates, or any of their respective executives or employees (including Executive), it is expected that the Company will have business activities and have valuable business relationships within its industry throughout the world, and (C) as part of his responsibilities, Executive will be traveling in furtherance of the Company’s business and its relationships. Executive agrees and acknowledges that the potential harm to the Company and its Subsidiaries and Affiliates of the nonenforcement of Section 5 and this Section 6 outweighs any potential harm to Executive of its enforcement by injunction or otherwise. Executive acknowledges that he has carefully read this Agreement and has given careful consideration to the restraints imposed upon Executive by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary

9

information of the Company now existing or to be developed in the future. Executive expressly acknowledges and agrees that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical area.

7. Executive’s Representations. Executive hereby represents and warrants to the Company that (a) the execution, delivery and performance of this Agreement by Executive do not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which Executive is a party or by which he is bound, (b) Executive is not a party to or bound by (i) any employment agreement with any other person or entity or (ii) any noncompete agreement or confidentiality agreement with any other person or entity that would in any way limit Executive’s ability to fulfill his obligations to the Company under this Agreement or otherwise, and (c) upon the execution and delivery of this Agreement by Syniverse, this Agreement shall be the valid and binding obligation of Executive, enforceable in accordance with its terms.

25. Provisions Relating to Section 409A of the Code.

(a) General. This Agreement shall be interpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder (and any applicable transition relief under Section 409A of the Code) (“Section 409A”). Nevertheless, the tax treatment of the amounts or benefits provided under the Agreement is not warranted or guaranteed. Neither the Company nor its directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by Executive as a result of the application of Section 409A.

(b) Separation from Service. Notwithstanding anything in this Agreement to the contrary, to the extent required by Section 409A, the severance payments under Section 4(d)(i) and 4(d)(ii), whether payable by reason of Sections 4(b), (d), (e) or (f), and any other amount or benefit that would otherwise be payable or distributable hereunder by reason of Executive’s termination of employment (collectively, the “Termination Benefits”), will not be payable or distributable to Executive unless the circumstances giving rise to such termination of employment meet any description or definition of “separation from service” in Section 409A (without giving effect to any elective provisions that may be available under such definition) (a “Separation from Service”). This provision does not prohibit the vesting of any amount upon Executive’s termination of employment or the determination of the amounts owed to him due to such termination. If this provision prevents the payment or distribution of any amount or benefit, such payment or distribution shall be made on the date, if any, on which an event occurs that constitutes a Separation from Service, or such later date as may be required by Section 4(g) herein.

15

(c) Timing of Waiver and Release of Claims. Whenever in this Agreement the provision of payment or benefit is conditioned on Executive’s execution and non-revocation of a waiver and release of claims, such waiver and release must be executed, and all revocation periods must have expired, within 60 days after the date of termination of Executive’s employment, but the Company may elect to commence payment at any time during such 60-day period. Notwithstanding the foregoing, in any case where the date of termination of employment and the 60^th day following the date of termination of employment fall in two separate taxable years, any payments required to be made to Executive that are conditioned on the waiver and release of claims and are treated as nonqualified deferred compensation for purposes of Section 409A shall be made in the later taxable year.

(d) Timing of Reimbursements and In-kind Benefits. If Executive is entitled to be paid or reimbursed for any taxable expenses under this Agreement, including but not limited to Sections 3(d), 3(e) and 22, and such payments or reimbursements are includible in Executive’s federal gross taxable income, the amount of such expenses reimbursable in any one calendar year shall not affect the amount reimbursable in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. No right of Executive to reimbursement of such expenses shall be subject to liquidation or exchange for another benefit.

(e) Treatment of Installment Payments. Each installment payment of severance benefits shall be considered a separate payment, as described in Treas. Reg. Section 1.409A-2(b)(2), for purposes of Section 409A.

(f) Notice and Cure. Notwithstanding anything to the contrary herein, any termination of Executive’s employment by Executive shall not constitute a termination for Good Reason unless (i) Executive has provided written notice to the Company of the existence of the condition constituting “Good Reason” within ninety (90) days of the initial existence of such condition, (ii) the Company has failed to remedy such condition within thirty (30) days of receiving written notice thereof, and (iii) such termination occurs within two years of the initial existence of such condition.

(g) Specified Employee Delay. Notwithstanding anything in this Agreement to the contrary, if and to the extent that any payment or benefit under this Agreement, or under any other agreement, plan, award or arrangement of the Company or its Affiliates, constitutes nonqualified deferred compensation for purposes of Section 409A and is payable to Executive by reason of Executive’s Separation from Service, then, in the event that Executive is deemed to be a “specified employee” within the meaning of Section 409A as determined by the Company, such payment or benefit shall not be made or provided until after the earlier of (i) the date that is the six (6) month anniversary of the date of Executive’s Separation from Service and (ii) the date of Executive’s death (the “Delayed Payment Date”). Any such payments and benefits to which Executive would otherwise be entitled during the period following Executive’s Separation from Service and ending on the Delayed Payment Date shall be paid or provided within fifteen (15) days following the Delayed Payment Date (unless another Section 409A compliant payment date

16

is set forth in this Agreement or the applicable arrangement). This Section 25(g) will apply only if and to the extent required to avoid the accelerated taxation and additional taxes, interest or penalties imposed under Section 409A.
