THIS CHIEF EXECUTIVE EMPLOYMENT AGREEMENT (“Agreement”) is entered into effective as of September 13, 2005 by and between CTI GROUP (HOLDINGS), INC., a Delaware corporation (the “Corporation”), having its principal place of business at 333 N. Alabama Street, Suite 240, Indianapolis, Indiana 46204 and JOHN BIRBECK (“Employee”), whose address is 64 Frieth Road, Marlow Bucks, SL7 2QU UK.

Background

The Corporation desires to employ the Employee and Employee desires to be employed by the Corporation on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements hereinafter set forth, the parties hereto, intending to be legally bound hereby, agree as follows:

Section 1. Employment and Duties.

(a) Upon the terms and conditions set forth herein, the Corporation hereby agrees to employ the Employee, and the Employee agrees to accept such employment and to perform his duties and responsibilities hereunder. Employee shall serve as the President and Chief Executive Officer of the Corporation and in such positions as reasonably may be assigned by the Board of Directors of the Corporation (the “Board”) or the Executive Committee of the Board (the “Executive Committee”). In the performance of services hereunder, Employee shall devote his best efforts and essentially all of his time during normal business hours to the business of the Corporation, subject to vacations and sick leave. Employee shall, subject to the direction of the Board or the Executive Committee, have, such authority and perform such duties and functions incidental to the position that he holds with the Corporation or such other duties and functions as may from time to time be assigned to him by the Board. Employee’s responsibilities will include, without limitation, the duties and responsibilities customarily associated with a Chief Executive Officer and Executive Committee. Employee shall cooperate fully with the Board, the Executive Committee and the other executive officers of the Corporation. Employee shall also be available to assist subsidiaries and affiliates of the Corporation. Employee shall not engage in any other business activity during the term of this Agreement which may interfere with his ability to discharge his duties and responsibilities to the Corporation.

(b) Employee represents to the Corporation that he is not subject or a party to any employment agreement, non-competition covenant, non-disclosure agreement or other agreement, covenant, understanding or restriction which would prohibit Employee from executing this Agreement and performing fully his duties and responsibilities hereunder, or which would in any manner, directly or indirectly, limit or affect the duties and responsibilities which may now or in the future be assigned to Employee by the Corporation.

Section 2. Employment Term. Unless sooner terminated in accordance with the provisions of this Agreement, the term of this Agreement shall commence on September 13, 2005 and shall continue for one year and thereafter shall continue for additional one-year periods unless either party gives the other party written notice of non-renewal at least 90 days prior to any anniversary date of this Agreement. As used herein, the term “Employment Term” shall refer to the foregoing period.

Section 3. Compensation. For all services rendered by the Employee under this Agreement, the Corporation shall pay Employee an annual salary (the “Salary”) at the rate of $275,000 for the Employment Term, less withholding required by law or agreed to by Employee, payable in accordance with the Corporation’s customary and usual payroll practice for its employees. The Corporation agrees that the Salary will be reviewed at least annually by the Board to determine if an increase is appropriate, which increase shall be in the sole discretion of the Board. The Salary shall not be decreased during the Employment Term. Employee agrees that he will waive any fee payable to him for his services as Chairman of the Board of Directors.

Section 4. Bonus and Additional Benefits.

(a) Bonus. No later than January 31 of each calendar year that Employee is employed by the Corporation pursuant to this Agreement, beginning January 1, 2006, Employee and the Corporation’s Board of Directors will confer and agree on targets and/or goals to be achieved for that calendar year and the amount of bonus to be paid to Employee depending on the extent of attainment of such targets and/or goals. The agreement reached by Employee and the Board shall be attached as an addendum to this Agreement each calendar year. The parties agree that the amount of bonus payable to Employee for full achievement of all targets and/or goals in any calendar year shall be no less than $250,000 and may exceed that amount if deemed appropriate by the Board in its sole discretion. In the event that Employee’s employment with the Corporation ends during the course of a calendar year, Employee shall be eligible for a pro rata amount of the bonus he would have received (if any) if he had remained employed for the full calendar year. For the period September 13, 2005 through December 31, 2005, the Corporation shall pay Employee a bonus in the amount of $62,500. All bonus payments shall be made to Employee by the end of January of the year following the year for which the bonus is payable. Any such Bonus shall be in lieu of any cash or other bonuses provided by the Corporation to its employees or senior executives generally, and Employee shall not be entitled to any such cash or other bonuses.

(b) Additional Benefits. Employee shall be entitled to five (5) weeks (25 working days) of paid vacation per year, with no right to carry over vacation to the next year, but unused vacation may be sold back to the Corporation.

Employee shall be paid a non-accountable automobile allowance of $500 per month for each full month during the Employment Term, payable in accordance with the Corporation’s customary and usual payroll practices for its employees.

During the period that Employee is employed by the Corporation pursuant to this Agreement, the Corporation will provide Ms. Amanda Powell with economy class air fare for up to 12 round trips from the United States to the United Kingdom each full calendar year (and a pro rata number of such trips for any partial calendar year of such employment), and will reimburse her for the amount she pays to obtain health insurance coverage for herself (up to the amount the Corporation pays for individual coverage for the Corporation’s employees).

The Corporation will reimburse Employee for the amount he pays for temporary apartment rental (not to exceed $1,800.00 per month without the prior approval of the Corporation) until such time as Employee has made arrangements for permanent housing or for six months, whichever is less. Employee shall also be paid a furnishing and household goods allowance in the amount of $12,000. In the event that Employee moves his household goods from the United Kingdom to the United States, he will be reimbursed for the lesser of his actual reasonable relocation expenses associated with such move or $80,000.

Section 5. Fringe Benefits. Except as set forth in Section 4, Employee shall be entitled to all normal and usual benefits (including health insurance) provided by the Corporation to its senior executives generally, including, but not limited to reimbursement for reasonable expenses incurred in connection with performing services for the Corporation upon presentation of an itemized account and written proof of such expenses in accordance with policies established by the Corporation and participation in any health or hospitalization plans. This provision shall not obligate the Corporation to provide any specific benefits and shall not prohibit the Corporation from changing such benefits. Employee alone shall be responsible for the payment of all federal, state and local taxes in respect of payments to be made and benefits to be provided under this Agreement.

Section 6. Stock Options. The Corporation shall grant to Employee, no later than 30 days after the effective date of this Agreement, a stock option to purchase 500,000 shares of Class A common stock of the Corporation on the date of the grant, which shares of such grant shall vest on the date of the grant. The Corporation shall grant to Employee a stock option to purchase an additional 250,000 shares of Class A common stock of the Corporation on September 13, 2006 and another 250,000 shares of Class A common stock of the Corporation on September 13, 2007, which shares of such grants shall vest on the dates of the grants (provided that Employee is employed as Chief Executive Officer and President of the Corporation on each of said vesting dates). The exercise price per share for each such option shall be the fair market value of the common stock of the Corporation on the dates of each of the grants.

Section 7. Confidential Information. For purposes of this Section 7, Confidential Information shall mean all confidential and proprietary technical, business and financial information of the Corporation and its affiliates, including, but not limited to, marketing and financial information, personnel, sales and statistical data, plans for future development, computer programs, information and knowledge pertaining to products and services offered, inventions, innovations, designs, ideas, plans, trade secrets, proprietary information, construction, advertising, sales methods and systems, sales and profit figures, customer and client lists, and relationships between the Corporation and its affiliates, customers, clients, suppliers and others who have business dealings with the Corporation and its affiliates, information with respect to various techniques, procedures, processes and methods and any other information acquired, learned, used or developed by Employee or others during his employment by the Corporation. Employee recognizes and acknowledges that by reason of his employment by and service to the Corporation (both during the Employment Term and before or after it), he has had and will continue to have access to Confidential Information. Employee acknowledges that such Confidential Information is a valuable and unique asset and Employee agrees that he will not, either during or after his employment by the corporation, use any Confidential Information for his own commercial benefit or the benefit of others nor disclose any Confidential Information to any person, firm or corporation not connected with the Corporation for any reason whatsoever except as his duties hereunder may require or as authorized in writing by the Board or the Executive Committee. However, Employee shall be relieved of his responsibilities under this Section 7 with respect to any Confidential Information which is in the public domain through no fault of Employee. All documents, magnetic media and other materials containing Confidential Information made or compiled by or made available to Employee during the course of his employment, and all copies thereof, are and shall be the property of the Corporation and shall be delivered to the Corporation by Employee immediately upon the conclusion of his employment.

Section 8. Inventions and Ideas; Ownership of Work Product.

(a) All work produced by Employee in the course of his employment under this Agreement including, without limitation, all inventions, creations, expressions, improvements, computer programs, specifications, operating instructions and all other documentation, whether copyrightable or uncopyrightable, or patentable or unpatentable, which are first conceived, made or otherwise originated or acquired, or first actually or constructively reduced to practice during his employment by the Corporation or within six (6) months following expiration or termination hereof, whether preliminary or final, and on whatever media rendered (collectively, the “Work Product”), shall be deemed work made for hire and made in the course of services rendered for the Corporation and shall be the sole and exclusive property of the Corporation. The Corporation shall have the sole, absolute and unlimited right throughout the world to protect by patent or copyright, and to make, have made, use, reconstruct, repair, modify, reproduce, publish, distribute and sell the Work Product, in whole or in part, or combine the Work Product with other matter, or not use the Work Product at all, as it sees fit.

(b) To the extent that title to the Work Product may not, by operation of law, vest in the Corporation, or such Work Product may not be considered to be work made for hire, the Employee hereby irrevocably agrees to transfer and assign to the Corporation in perpetuity all worldwide right, title and interest in and to the patent rights, copyrights, trade secrets and other proprietary rights (including, without limitation, applications for registration thereof, and all priority rights therein under applicable international conventions for the protection of such rights) in, and ownership of, the Work Product that the Employee may have, as and when such rights arise.

(c) Employee hereby agrees, without cost to the Corporation other than reimbursement of reasonable expenses, to cooperate fully with the Corporation in executing all applications for patents, copyrights, assignments and other documents, papers and writing and to perform all acts and do all things necessary to protect or vest the Corporation’s rights in or to the Work Product, whether during the term of his employment or at anytime thereafter. If the Corporation is unable, after reasonable effort, to secure Employee’s signature on any documents or documents needed to apply for or prosecute any patent, copyright, or right or protection relating to any Work Product, whether because of Employee’s physical or mental incapacity or for, any other reason whatsoever, Employee hereby irrevocably designates and appoints the Corporation and its duly authorized officers and agents as Employee’s agent and attorney-in-fact, to act for and in his behalf and stead to execute and file any such application or applications and to do all other lawfully permitted acts to further the prosecution and issuance of patents, copyrights, or similar protections thereon with the same legal force and effect as if executed by Employee.

Section 9. Non-Competition.

(a) During his employment by the Corporation and for a period of 90 days after the employment of Employee by the Corporation or any of its affiliates has ended (whether or not such employment is pursuant to this Agreement), Employee will not, directly or indirectly: (i) anywhere in the world own, manage, operate, join, control, finance or participate in the ownership, management, operation, control or financing of, render financial assistance to, or be connected as an officer, director, employee, partner, principal, agent, representative, consultant or otherwise with or use or permit his name to be used in connection with, any competing business; (ii) contact or attempt to persuade any agents or employees of the Corporation or any of its affiliates to terminate their relationship with the Corporation or any of its affiliates, nor do any act which may result in the impairment of the relationship between the Corporation or any of its affiliates and its agents or employees; or (iii) in anyway, for his own account, or for the account of any person, firm, corporation or enterprise engaged in a competing business, directly or indirectly through others, sell to, solicit, contact, serve, or cater to any person, firm, corporation or other enterprise which is or was a customer of the Corporation during his employment by the Corporation, regardless of the time when, or the person by or through whom, said customer became a customer of the Corporation; provided, however, that nothing in this Section 9 shall prohibit Employee from owning interests of less than one percent (1%) in companies with securities traded on a national securities exchange or quoted on the National Association of Securities Dealers, Inc. Automated Quotation System.

Section 10. Equitable Relief.

(a) Employee acknowledges that the restrictions contained in Sections 7, 8 and 9 hereof are reasonable and necessary to protect the legitimate interests of the Corporation and its affiliates, that the Corporation would not have entered into this Agreement in the absence of such restrictions, and that any violation of any provision of those Sections will result in irreparable injury to the Corporation. Employee represents that his experience and capabilities are such that the restrictions contained in Section 9 hereof will not prevent Employee from obtaining employment or otherwise earning a living at the same general level of economic benefit as anticipated by this Agreement. Employee further represents and acknowledges that (i) he has been advised by his own independent legal counsel in respect of this Agreement, and (ii) that he has had full opportunity, prior to execution of this Agreement, to review thoroughly this Agreement with his counsel.

In the event that any of the provisions of Sections 7, 8 and 9 hereof should ever be adjudicated to exceed the time, geographic, product or service, or other limitations permitted by applicable law in any jurisdiction; then such provisions shall be deemed reformed in such jurisdiction to the maximum time, geographic, product or service, or other limitations permitted by applicable law.
