                              EMPLOYMENT AGREEMENT

            THIS AGREEMENT is made on and as of February 12, 2001 (the
"Agreement Date") by and between ANTHONY P. JOHNS ("Employee") and CTI GROUP
(HOLDINGS) INC., a Delaware corporation ("Company").

                                   BACKGROUND

            A. Employee is and has been for approximately ten years the
President and Chief Executive Officer of Company.

            B. Company is a party to that certain Agreement and Plan of Merger
dated February 2, 2000, as amended, pursuant to which Company will be the
surviving corporation of the merger contemplated therein (the "Transaction").

            C. Company desires to employ Employee, and Employee desires to be
employed by Company, upon the conditions and terms herein set forth.

            D. The execution of this Agreement is a condition to the
consummation of the Transaction.

            NOW, THEREFORE, intending to be legally bound hereby, and in
consideration of the mutual covenants set forth herein, Employee and Company
agree as follows:

1. Employment and Duties. Company shall employ Employee as Company's President
and Chief Executive Officer during the term of employment set forth in Section 2
hereof. Employee shall have full and exclusive responsibility for the management
of the day-to-day operations of Company, subject to the direction of Company's
Board of Directors (the "Board"). Employee shall also have such other
responsibilities and duties, consistent with his position and expertise, as may
from time to time be prescribed by the Board. Employee shall devote his full
time, energy, skill and best efforts to the business and affairs of Company, and
shall not, during the term of this Agreement, be engaged in any other business
activity whether or not such business activity is pursued for gain, profit or
other pecuniary advantage; provided, however, that nothing contained herein
shall be construed as preventing Employee from (i) engaging in charitable
activities, or (ii) serving as a member of the board of directors of an entity
so long as such entity does not, directly or indirectly, in any manner compete
with Company, or (iii) investing his assets in such form or manner as (A) will
not require any services on Employee's part in the operations of the affairs of
the company in which such investments are made (other than services to Company
and its affiliates) and (B) will not be an investment in any company which
competes, directly or indirectly, with Company in any manner; provided,
further, that the activities permitted in the foregoing subsections (i), (ii)
and (iii) shall not, either alone or together with other activities permitted
under the same subsection or together with other activities permitted under any
or all of the other of such subsections, interfere in any material way with
Employee's responsibilities under this Agreement. In addition, Company agrees to
use its reasonable best efforts to cause Employee to be nominated and elected as
a member

<PAGE>

of the Board of the Company during the Term. Employee shall be employed by
Company, and shall spend the majority of his business time, at the Company's
location at Indianapolis, Indiana; provided, however, that the Board, in its
discretion shall have the right to relocate the Company's headquarters,
presently located in Indianapolis, Indiana (and consequently change Employee's
business location) if doing so would be in the Company's best interests as
determined by the Board.

2. Term. The term of Employee's employment under this Agreement shall be a
period of three (3) years commencing on the Effective Time of the Agreement and
Plan of Merger, and ending on the third anniversary of the Effective Time,
unless sooner terminated in accordance with the other provisions hereof (the
"Term").

3. Compensation.

            3.1 Salary. Company shall pay to Employee as compensation for all
services rendered hereunder a base salary of $250,000 per year ("Salary"),
payable in accordance with Company's normal payroll practices for employees.
Company shall deduct or cause to be deducted from the Salary all taxes and
amounts required by law to be withheld. Employee's Salary shall be reviewed by
the Board annually, but shall not be reduced as a result of such review.

            3.2 Benefits. During the Term, subject to the other provisions of
this Agreement, Employee shall be entitled to participate and shall be included
in any savings, 401(K), pension, profit-sharing, group medical, group disability
or similar plan adopted by Company, now existing or established hereafter, to
the extent he is eligible under the general provisions thereof.

            3.3 Cash Bonus. In addition to his Salary, Employee may also receive
cash bonuses on such terms, at such times and in such amounts as the Board may
determine in its sole discretion ("Cash Bonus"). The Company will establish each
year a program of individual and/or group bonuses based on performance,
profitability and such other factors as may be deemed to be appropriate by the
Board.

            3.4 Fringe Benefits.

            3.4.1 Vacation. Employee shall be entitled to twenty-five (25) days
of paid vacation during each year, with up to ten (10) days of unused vacation
time each year to accrue and be carried over to the next year.

            3.4.2 Reimbursement of Expenses. Employee is authorized to incur
ordinary, necessary and reasonable expenses in the course of Company's business,
in accordance with Company's standard expense and expense reimbursement
procedures applicable to directors or executive employees of Company. Company
shall reimburse Employee for such expenses upon presentation by the Employee of
an itemized account of such expenditures in a manner reasonably prescribed by
Company, unless such expenses have been paid directly by the Company.

            3.4.3 Automobile. Company shall provide Employee with an automobile
allowance of $925 per month. Employee shall maintain liability, collision and
comprehensive insurance covering any such automobile, in such amounts and on
such terms as are required by applicable law and shall provide Company with
proof of such coverage as and when requested. The cost of insurance coverage,
together with operating costs, repairs and maintenance shall be paid by Employee
but, to the extent eligible therefor, shall be reimbursed under Section 3.4.2.

            3.4.4. Accommodation and Moving Allowance. Company shall provide
Employee with an accommodation allowance in the amount of $1,300 per month
during the Term. In addition, Company will reimburse Employee for all moving and
other relocation expenses incurred by Employee as a result of any relocation of
the Company's headquarters. In addition, Company will provide housing in
Indianapolis, Indiana for the Employee (as well as up to two (2) other employees
previously residing in the Philadelphia, Pennsylvania area) for a period of one
(1) year following the commencement date of this Agreement.

            3.5 Entire Compensation. The compensation provided for in this
Section shall be the full consideration for the services to be rendered by
Employee to Company hereunder.

      4. Termination.

            4.1 Notice of Termination. Except as otherwise provided herein, any
termination by Company or by Employee shall be communicated by written Notice of
Termination to the other party hereto. As used in this Agreement, "Notice of
Termination" means a notice specifying the termination provision in this
Agreement relied upon and setting forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of Employee's
employment under the provision specified. As used in this Agreement, "Date of
Termination" shall mean the date specified in the Notice of Termination or,
where notice is not required, the date employment actually terminates.

            4.2 Grounds for Termination.

            4.2.1 Termination upon Death. Employee's employment with Company and
all of Employee's rights to compensation and benefits hereunder shall
automatically terminate upon his death, except that Employee's heirs, personal
representatives or estate shall be entitled to any unpaid portion of his Salary,
his earned but unpaid bonus, if any, and accrued benefits up to the Date of
Termination and shall also be entitled to reimbursement for any expenses
incurred by Employee hereunder.

            4.2.2 Termination upon Disability. If Employee becomes disabled,
Employee shall continue to receive all of his compensation and benefits in
accordance with Section 3 for a period of six months following the Onset of
Disability (as defined in this Section 4.2.2). Any amounts due to Employee under
this Section 4.2.2 shall be reduced, dollar-for-dollar, by any amounts received
by Employee under any disability insurance policy or plan ("Disability
Payments") provided to

                                       3
<PAGE>

Employee by Company. "Onset of Disability" means the first day on which Employee
shall be unable to attend to the regular affairs of Company on a full time basis
by reason of physical or mental incapacity, sickness or infirmity. Company will
notify Employee promptly upon having made a determination of the Onset of
Disability. If Employee's disability continues for more than six (6) months
after the Onset of Disability or for periods aggregating more than six (6)
months during any twelve (12) month period, then, Company shall have the right
to terminate Employee's employment immediately upon notice, and all of his
rights to compensation and benefits hereunder shall simultaneously terminate,
except that (i) Employee shall be entitled to any unpaid portion of his Salary
and accrued benefits up to the Date of Termination and to any benefits which are
to be continued or paid after the Date of Termination in accordance with the
terms of the corresponding benefit plans, if any, and (ii) Employee shall be
paid the "severance amounts" described in Section 4.3. reduced by the sum of any
and all Salary amounts paid to Employee by Company subsequent to the Onset of
Disability, and any and all Disability Payments. A determination of Employee's
disability shall be subject to the certification of a qualified physician agreed
to by the Company and the Employee or, in the event of the Employee's incapacity
to designate a physician, the Employee's legal representative. In the absence of
agreement between the Company and the Employee, each party shall nominate a
qualified physician and the two physicians shall select a third physician, who
shall make the determination as to disability.

            4.2.3 Termination for Cause. At any time during the Term, Company
may terminate Employee's employment hereunder for Cause (as defined herein),
effective immediately upon notice to Employee, if at a meeting of the Board (of
which Employee had been given notice and an opportunity to present his case) a
resolution was duly adopted by a majority of the entire Board (subject to the
last sentence of this paragraph) finding that, in the good faith judgment of the
Board, (1) an event constituting Cause has occurred, and (2) either Employee had
a reasonable opportunity to take remedial action but failed or refused to do so,
or an opportunity to take remedial action would not have been meaningful or
appropriate under the circumstances. If Employee is then a member of the Board,
he shall not, in his capacity as a member of the Board, be entitled to notice
of, or to participation in, or to be counted as or vote as a director at such
meeting.

            For purposes of this Agreement, Cause shall mean: (1) Employee
materially breaches, neglects or fails to significantly perform to the
reasonable satisfaction of the Board, his duties under this Agreement (other
than such failure resulting from Employee's incapacity due to physical or mental
illness within the meaning of Section 4.2.2), (2) Employee commits an act of
dishonesty or breach of trust which is materially harmful to the business of
Company, either during the Term or in connection with the Transaction, (3)
Employee violates or breaches any of the provisions of this Agreement, and the
Employee shall have either failed to remedy such breach within 30 days from his
receipt of written notice from Company identifying the breach in reasonable
detail and demanding that he remedy such breach, or shall have failed to take
all reasonable steps to that end during such 30-day period and thereafter, (4)
Employee's act or omission to act intentionally results in or is intended to
result directly in gain to or personal enrichment of Employee at Company's
expense or, (5) Employee is indicted for or convicted of a felony or any crime
involving larceny,

                                       4
<PAGE>

embezzlement or moral turpitude (which, in the case of moral turpitude,
materially adversely affects the Company in any financial manner).

            On termination of this Agreement pursuant to this Section 4.2.3,
Employee shall continue to be bound by the restrictions set forth in Section 5,
any and all unvested Company stock options shall be deemed canceled and
terminated, and all rights to compensation and benefits of Employee shall cease
as of the Date of Termination, except Employee shall be entitled to any unpaid
portion of his Salary and benefits earned to the Date of Termination.

            4.2.4 (a) Termination By Employee. Employee may, upon ninety (90)
days prior written notice to Company terminate his employment under this
Agreement. Upon such termination under this Section 4.2.4(a) Employee shall
continue to be bound by the restrictions set forth in Section 5 and shall be
entitled to receive only the severance amounts described in Section 4.3 and,
unless such termination is for "Good Reason" under Section 4.2.4(b); any and all
unvested Company stock options then held by Employee shall be canceled and
terminated. To the extent that the provisions of any company stock option plan
are inconsistent with the terms of this Agreement as it applies to Employee, the
terms of this Agreement shall govern with respect to cancellation and
termination of his unvested options.

            (b) Termination For Good Reason. Employee may otherwise terminate
his employment hereunder only for Good Reason; provided, however, that the
provisions of this Section 4.2.4(b) and Section 4.3 shall apply to a termination
by Employee only if Employee shall have first given Company thirty (30) days
written notice of his intention to terminate his employment pursuant to this
Section 4.2.4(b), specifying the reason(s) for such termination, and provided
further, that Company shall not have cured or remedied the reason(s) specified
in such notice prior to the expiration of thirty (30) days after receipt of such
written notice. For purposes of this Agreement, "Good Reason" means, (1) any
assignment to Employee of any material duties other than those contemplated by,
or any material limitation of the powers of Employee in any respect not
contemplated by Section 1 hereof, (2) any removal of Employee from or any
failure to re-elect Employee to any of the positions indicated in Section 1
hereof, except (i) in connection with termination of Employee's employment for
Cause or (ii) with respect to Employee's position as a member of the Board, (3)
a reduction in Employee's rate of compensation, or a material reduction in
Employee's fringe benefits as set out in Section 3 hereof, or (4) the occurrence
of any "change in control". For purposes of this Section 4.2.4, the term "change
in control" shall mean [a change in control of a nature that would be required
to be reported in response to Item 5(f) of Schedule 14A of Regulation 14A
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), whether or not the Company is then subject to such reporting requirement;
provided that, without limitation, such a Change in Control shall be deemed to
have occurred if (1) any "person" (as such term is used in Sections 13(d) and
14(d) of the Exchange Act) is or becomes the "beneficial owner" (as defined in
Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing 50% or more of the combined voting power of the Company's
then outstanding securities; (2) during any period of two consecutive years
during the term of this Agreement, individuals who at the beginning of such
period constitute the Board of

                                       5
<PAGE>

Directors and any new director, whose election by the Board of Directors or
nomination for election by the Company's stockholders was approved by a vote of
at least a majority of the directors then still in office who either were
directors at the beginning of the period or whose election, or nomination for
election was previously so approved, cease for any reason to constitute a
majority thereof; or (3) the business of the Company for which Employee's
services are principally performed is disposed of by the Company pursuant to a
partial or complete liquidation of the Company, a sale of assets (including
stock of a subsidiary) of the Company, or otherwise. Upon termination under this
Section 4.2.4(b), Employee shall continue to be bound by the restrictions set
forth in Section 5 and shall be entitled to: (i) payment of the severance
amounts described in Section 4.3 and (ii) immediate vesting of fifty percent
(50%) of any unvested Company stock options then held by Employee.

            (c) Non-Renewal of Employment upon Expiration of Term. If upon the
expiration of the Initial Term the parties do not renew Employee's employment,
Employee shall be entitled to payment of the severance amounts described in
Section 4.3.

            4.2.5 Other Termination BY Company. Anything in this Agreement to
the contrary notwithstanding, Company shall have the right to terminate
Employee's employment hereunder without cause, for any reason or for no reason,
upon ninety (90) days prior written notice. Upon such termination under this
Section 4.2.5, Employee shall continue to be bound by the restrictions set forth
in Section 5 and shall be entitled to: (i) payment of the severance amounts
described in Section 4.3 and (ii) immediate vesting of fifty percent (50%) of
any unvested Company stock options then held by Employee.

            4.3 Severance Amounts. If Employee's employment is terminated by
Employee for Good Reason or pursuant to Section 4.2.4(a), then, subject to
Employee's compliance with the provisions and restrictions of Sections 5.1, 5.2
and 5.3, (i) the Company shall pay the Employee his Salary through the Date of
Termination at the rate in effect at the time Notice of Termination is given and
(ii) in lieu of any further salary payments to the Employee for periods
subsequent to the Date of Termination, Company shall pay, as severance pay to
the Employee, an amount equal to the product of (A) the Employee's annual Salary
in effect as of the Date of Termination divided by 12; multiplied by (B) the
number 24, (the "severance amounts) such payment to be made as soon as
reasonably possible with due regard to the financial status of the Company but
not later than (i) ninety (90) days following the Date of Termination with
respect to at least the first $250,000 of such amount, and (ii) one hundred
eighty (180) days following the Date of Termination with respect to the balance
of such amount. In the event the balance of the severance amount has not been
paid to Employee within said ninety (90) day period, the unpaid balance shall
bear interest, from such ninetieth (90th) day until paid, at an annual rate of
interest equal to the sum of the "prime rate" publicly announced from time to
time by First Union National Bank plus 4.00 percent. In the event that Company
fails to make either payment pursuant to this Section, Employee shall cease to
be bound by the restrictions set forth in Section 5.3.

            4.4 Procedure Upon Termination. On termination of employment
regardless of the reason, Employee shall promptly return to Company all
information regarding Company in whatever manner or media such information is
stored or maintained, and all documents (including copies) and other property of
Company, including without limitation, customer lists, manuals, letters,
materials, reports, and records in his possession or control no matter from whom
or in what manner acquired.

5. Employee's Covenants.

            5.1 Discoveries. Employee shall communicate to Company and preserve
as confidential information of Company each discovery, idea, design, invention
and improvement relating in any manner to Company's business, whether or not
patentable and whether or not reduced to practice, which is conceived, developed
or made by Employee, whether alone, or jointly with others, at any time during
the Term hereof (such discoveries, ideas, designs, inventions and improvements
are referred to as "Employee's Discoveries"). All of Employee's Discoveries
shall be Company's exclusive property, and all of Employee's right, title and
interest therein are hereby irrevocably assigned to Company. Employee shall not,
except with Company's express prior written consent, or except in the proper
course of his employment with Company, use any of Employee's Discoveries for his
own benefit or the benefit of any Person (as defined herein), or disclose any of
Employee's Discoveries to any outside Person through publication or in any other
manner.

            For purposes of this Agreement, the term "person" means a natural
person, corporation, partnership, trust, estate, joint venture, sole
proprietorship, government (and any branch or subdivision thereof), governmental
agency, association, cooperative or other entity.

            5.2 Nondisclosure. At all times during and after the Term, Employee
shall keep confidential and shall not, except with Board's express prior written
consent, or except in the proper course of his employment with Company, directly
or indirectly, communicate, disclose, divulge, publish, or otherwise express, to
any Person, or use for his own benefit or the benefit of any Person, any trade
secrets, confidential or proprietary knowledge or information, no matter when or
how acquired, concerning the conduct and details of Company's business,
including without limitation names of customers and suppliers, marketing
methods, trade secrets, policies, prospects and financial condition. For
purposes of this Section 5.2, confidential information shall not include any
information which is now known by or readily available to the general public or
which becomes known by or readily available to the general public other than as
a result of any improper act or omission of Employee.

            5.3 Noncompetition. During the Term hereof and for a period of two
(2) years thereafter, Employee shall not, except with Company's express prior
written consent, directly or indirectly, in any capacity, for the benefit of any
Person:

            (1) Communicate with or solicit or employ any Person who is or
during such period becomes a customer, supplier, employee, salesman, agent or
representative of Company, in any manner which interferes or might interfere
with such Person's relationship with Company, or

                                    7
<PAGE>

in an effort to obtain such Person as a customer, supplier, employee, salesman,
agent, or representative of any business in competition with Company in North
America or the United Kingdom.

            (2) Establish, engage, own, manage, operate, join or control, or
participate in the establishment, ownership, management, operation or control
of, or be a director, officer, employee, salesman, agent or representative of,
or be a consultant to, any Person in any business in competition with Company,
at any location in North America or the United Kingdom or any other location
where Company now conducts or during the Term hereof begins conducting any
business, or act or conduct himself in any manner which he would have reason to
believe harmful or contrary to the best interests of Company.

            5.4 Enforcement. Employee acknowledges that any breach by him of any
of the covenants and agreements of this Section 5 ("Covenants") will result in
irreparable injury to Company for which money damages could not adequately
compensate Company, and therefore, in the event of any such breach, Company
shall be entitled, in addition to all other rights and remedies which Company
may have at law or in equity, to have an injunction issued by any competent
court enjoining and restraining Employee and/or all other Persons involved
therein from continuing such breach. The existence of any claim or cause of
action which Employee or any such other Person may have against Company shall
not constitute a defense or bar to the enforcement of any of the Covenants. If
Company is obliged to resort to litigation to enforce any of the Covenants which
has a fixed term, then such term shall be extended for a period of time equal to
the period during which a material breach of such Covenant was occurring,
beginning on the date of a final court order (without further right of appeal)
holding that such a material breach occurred or, if later, the last day of the
original fixed term of such Covenant.

            5.5 Consideration. Employee expressly acknowledges that the
Covenants are a material part of the consideration bargained for by Company and,
without the agreement of Employee to be bound by the Covenants, Company would
not have agreed to enter into this Agreement.

            5.6 Scope. If any portion of any Covenant or its application is
construed to be invalid, illegal or unenforceable, then the other portions and
their application shall not be affected thereby and shall be enforceable without
regard thereto. If any of the Covenants is determined to be unenforceable
because of its scope, duration, geographical area or similar factor, then the
court making such determination shall have the power to reduce or limit such
scope, duration, area or other factor, and such Covenant shall then be
enforceable in its reduced or limited form.

            5.7 Effect on Other Provisions. All payments to Employee under this
Agreement, including, without limitation, post-employment payments, if any,
under Section 4, shall be subject to Employee's compliance with the provisions
of this Section 5. If Employee fails to comply in any respect with any of such
provisions, his right to any future payments under this Agreement shall
terminate and the Company's obligations under this Agreement to make such
payments and provide such benefits shall cease, provided, however, that unless
Company shall have notified Employee in

                                       8
<PAGE>

writing within two (2) days following the Date of Termination that it intends to
contest Employee's right to payment under Section 4.3, Company shall remain
obligated to pay such amounts within the 90 day (or 180 day, as applicable)
period set forth in Section 4.3 and shall be constrained to seeking recovery
thereof under Section 6.13.
