          On February 2, 1998 (the "Closing Date"), pursuant to the terms of
          that certain Asset Purchase Agreement (the "Agreement"), dated as of
          February 2, 1998, by and among CTI Group (Holdings) Inc. (the
          "Company"), CTI Data Solutions (International) Ltd., an English
          company and a wholly-owned subsidiary of the Company ("CTI
          International") and Siemens plc, an English company  ("Siemens"), CTI
          International acquired the assets and substantially all the 
          liabilities of Siemens' Databit business division ("Databit").   
          Databit is engaged in the business of the design, development, 
          marketing, distribution, licensing, maintenance and support of 
          telecommunications call management software and services and owns 
          various license and contract rights, copyrights, trademarks, trade 
          secrets and other intellectual property and assets relating to these 
          products and services. 

          The purchase price was paid by CTI International in the form of a
          $2,000,000 Secured Promissory Note (the "Note") executed by CTI
          International in favor of Siemens.  The Note calls for CTI
          International to pay annual interest of ten percent (10%) quarterly in
          arrears until February 2, 2001 (the "Maturity Date").  The principal
          amount of the Note is due on the Maturity Date.  The Company executed
          a Guaranty (the "Guaranty") in favor of Siemens to guarantee CTI
          International's performance under the Note.  Siemens was also granted
          a security interest in the assets of Databit purchased by CTI
          International, pursuant to a Debenture (the "Debenture") executed by
          CTI International in favor of Siemens, and all of the assets of the
          Company, including the Company's ownership interest in each of the
          Company's wholly-owned subsidiaries, pursuant to a Security Agreement
          (the "Security Agreement") and a Collateral Pledge Agreement (the
          "Pledge Agreement") executed by the Company in favor of Siemens. 

          Copies of the Agreement, the Note, the Guaranty, the Debenture, the
          Security Agreement and the Pledge Agreement are attached hereto as

itself as carrying on the Business in succession to the Seller ("Goodwill");

               (x)  The know-how and the marketing information (including 
that comprised in or derived from formulae, designs, specifications,

used by or in the Business.

               (xi) All the Seller's rights against third parties (including but
not limited to rights under or in respect of warranties, representations,
guarantees and indemnities) in respect of the Business of any of the Assets; 

               (xii) Cash or cash equivalents in an amount equal to the 
amount necessary so that the Total Assets (as defined below) of the Business 
as of the Closing Date shall equal the Total Liabilities (as defined below) 
of the Business as of the Closing Date (the "Required Cash Amount").  
Notwithstanding the foregoing sentence, the Required Cash Amount shall not be 
less than UKL 287,000.  "Total Assets" and "Total Liabilities" shall have the 
meanings normally ascribed to such terms under United Kingdom generally 
accepted accounting principles; and

               (xiii) All of Seller's right, title and interest in and to all 
patents, trademarks and trade names, trademark and trade name registrations,

registrations, the applications therefor and the licenses with respect 
thereto relating exclusively to the Business, a list of which is set forth in 
Schedule 1.1(a)(xiii), and all technology, proprietary information and 
know-how relating exclusively to the Business, together with the goodwill of 
the Business appurtenant thereto and any rights, claims or choses of action 
relating to or deriving from any of the foregoing together with any 
unregistered intellectual property used exclusively in the Business, other 
than the name and logo "Siemens".

          (b)  Subject to Section 1.1(c), the Seller shall assign to the 
Buyer and the Buyer shall accept an assignment of and shall take over from 
the Seller at and with effect from Closing the benefit and burden of all 
contracts relating to the Business (the "Contracts") and the Seller will if 
so requested by the Buyer on or after Closing join with the Buyer in sending 
out a notice of assignment thereof to such of the other parties to the 
Contracts as the Buyer may so request, provided that nothing in this 
agreement:

               (1)  Shall require the Buyer to satisfy any obligation 
requiring performance before Closing other than those obligations expressly 
assumed by the Buyer pursuant to this Agreement;

               (2)  Shall make the Buyer liable for any act, neglect, default 
or omission in respect of any of the Contracts prior to Closing or for any 
claim, expense, loss or damages arising from any failure to obtain the 
consent or agreement of any third party to this Agreement or for any breach 
of any of the Contracts caused by this Agreement or its completion.  
Notwithstanding the foregoing, in the event any such third party requires a 
novation fee with respect to any Contract, the parties hereto hereby agree to 
consult with one another and to determine a mutually agreeable course of 
action with respect to the payment of such novation fee; or

               (3)  Shall impose any obligation on the Buyer for or in 
respect of any product delivered by the Seller or any service performed by 
Seller prior to Closing other than normal warranty repairs in the ordinary 
course of business.

                                       3

<PAGE>


          (c)  Insofar as the benefit or burden of the Contracts cannot be 
assigned to the Buyer except by an agreement of novation with, or consent to 
the assignment from, the person, firm or company concerned:

               (1)  The Seller shall at the Buyer's request use all 
commercially reasonable efforts with the co-operation of the Buyer to procure 
such novation or consent;

               (2)  Unless and until such Contracts shall be novated or 
assigned, the Seller shall hold the same in trust for the Buyer absolutely 
and the Buyer shall, (if such sub-contracting is permissible and lawful under 
the Contracts) as the Seller's agent or sub-contractor, perform all the 
obligations of the Seller thereunder; and

               (3)  Unless and until such Contracts shall be novated or 
assigned, the Seller will (so far as it lawfully may) give all reasonable 
assistance to the Buyer to enable the Buyer to enforce its rights under such 
Contracts.

     1.2       Purchase Price.  

          (a)  The purchase price (the "Purchase Price") for the Assets shall 
be US $2,000,000. 

          (b)  As of the Closing Date, Seller shall make a good faith 
estimate of the Required Cash Amount.  Promptly after the Closing Date, Buyer 
with the assistance and cooperation of personnel of the Business employed by 
Seller after the Closing Date (who, for these purposes, will be under the 
direction and supervision of Buyer), will prepare and present to Seller a 
balance sheet of the Business as of the Closing Date, which balance sheet 
shall be audited by public accountants selected by Buyer and approved by 
Seller, which approval shall not be unreasonably withheld (the "Adjusted 
Closing Date Balance Sheet").  The Adjusted Closing Date Balance Sheet shall 
be prepared in accordance with the same accounting methods, practices, 
procedures and policies, and using the same methods of estimates and 
judgments, used by Seller in preparing financial statements for the Business 
prior to Closing and shall be prepared as though the parties had not 
consummated the transactions contemplated by this Agreement save for the 
settlement of intercompany creditors which have been discharged.  The 
Adjusted Closing Date Balance Sheet shall be delivered to Seller no later 
than 30 days after the Closing Date. 

          (c)  For the purpose of preparing the Adjusted Closing Date Balance 
Sheet, Buyer and its accountants shall have the right to review the work 
papers of Seller and its accountant utilized in preparing the financial 
statements related to the Business.  The Adjusted Closing Date Balance Sheet 
shall be binding on Seller unless Seller presents to Buyer within 30 days 
after its receipt of the Adjusted Closing Date Balance Sheet from Buyer 
written notice of disagreement specifying in reasonable detail the nature and 
extent of the disagreement.

          (d)  If Buyer and Seller are unable to resolve any disagreement 
with respect to the Adjusted Closing Date Balance Sheet within 15 days after 
Buyer receives a timely notice of disagreement, which shall be no later than 
30 days after receipt by the Seller of the Adjusted Closing Date Balance 
Sheet, the items of disagreement alone shall be referred for final 
determination to KPMG, or if KPMG is unable or unwilling to make such final 
determination, to such other independent accounting firm as the parties shall 
mutually agree or, in the absence of agreement, to such other independent 
accounting firm as shall be 

                                       4

<PAGE>

nominated by the Institute of Chartered Accountants at the request of either 
party (KPMG or such other accounting firm is referred to herein as the 
"Independent Accountants").  Absent manifest error, the determination of the 
Independent Accountants shall be final and binding upon all parties to this 
Agreement.  The Adjusted Closing Date Balance Sheet (or, in the event of the 
Adjusted Date Balance Sheet requires amendment pursuant to Section 1.2(d)(ii) 
and (iii) below, the Adjusted Closing Date Balance Sheet as so amended) shall 
be deemed to be binding on Buyer and Seller upon (i) Seller's failure to 
deliver to Buyer a notice of disagreement within 30 days of its receipts of 
the Adjusted Closing Date Balance Sheet prepared by Buyer, (ii) resolution of 
any disagreement by mutual agreement of the parties after a timely notice of 
disagreement has been delivered, or (iii) notification by the Independent 
Accountants of their final determination of the items of disagreement 
submitted to them.  The fees and disbursements of the Independent Accountants 
shall be borne equally, one-half by Buyer and one-half by Seller.

          (e)  In the event that the Required Cash Amount as reflected on the 
Adjusted Closing Date Balance Sheet is less than the amount of cash and cash 
equivalents transferred at Closing pursuant to Section 1.1(a)(xii) (the 
"Transferred Cash"), Buyer shall pay to Seller an amount equal to the 
Transferred Cash less the Required Cash Amount.  In the event the Transferred 
Cash is less than the Required Cash Amount, the Seller shall promptly pay to 
Buyer an amount equal to the Required Cash Amount less the Transferred Cash.  

     1.3       Payment of Purchase Price.  At Closing, Buyer shall execute 
and deliver to Seller a promissory note (the "Note"), in substantially the 
form attached hereto as Exhibit C.  Buyer's performance under the Note shall 
be guaranteed by CTIG.  The principal amount of the Note shall be an amount 
equal to the Purchase Price.  Interest on the principal amount of the Note 
shall be calculated at the rate of ten percent (10%) per annum and shall be 
paid quarterly in arrears.  The principal amount of the Note shall be due and 
payable three (3) years from the date of the Closing; provided, however, that 
CTIG shall use commercially reasonable efforts to sell, within twelve (12) 
months of Closing, its United States telemanagement service bureau and that 
the net cash proceeds from such sale whenever concluded up to an amount equal 
to the Required Cash Amount shall be immediately paid to the Seller and 
shall, as soon as practicable following the date of such sale, be applied to 
reduce the then outstanding principal amount of the Note.  Contemporaneously 
with the execution and delivery of the Note, the Buyer shall cause CTIG to 
execute and deliver to the Seller a security agreement (the "Security 
Agreement") and Pledge Agreement (the "Pledge Agreement"), in substantially 
the form attached hereto as Exhibits E and F, respectively.  The Security 
Agreement shall grant the Seller a security interest (the "Security 
Interest") in the assets of CTIG subject and subordinate in priority only to 
any then existing security interests with respect to such assets and the 
security interests to be granted to a banking institution in connection with 
debt financing of the Business or CTIG.  The Pledge Agreement shall pledge 
CTIG's ownership interest in the equity securities of the Buyer and of each 
of the following wholly-owned subsidiaries of CTIG: (i) CTI Delaware 
Holdings, Inc., (ii) CTI Soft-Com, Inc., (iii) Plymouth Communications, Inc., 
and (iv) Telephone Budgeting Systems, Inc.  Buyer shall also execute and 
deliver to Seller a debenture (the "Debenture") and any other document 
necessary to grant the Seller a charge over the Assets under the laws of the 
United Kingdom.

     1.4       Allocation of Purchase Price.  The consideration provided for 
in Section 1.2 of this  Agreement and the Assumed Liabilities shall be 
allocated among the Assets as set forth on Schedule 1.4 subject to subsequent 
verification by the Buyer's independent auditors.

     1.5       Assumption of Liabilities.  Subject to the terms and 
conditions of this Agreement, at the 

                                       5

<PAGE>

Closing, Buyer shall assume and agree to perform, pay or discharge the 
liabilities and obligations of the Seller and the Company related to the 
Business set forth on Schedule 1.5 including all liabilities associated with 
the Contracts and all accounts payable set forth on the Adjusted Closing Date 
Balance Sheet (as defined below)  (the "Assumed Liabilities").  Except as set 
forth in this Section 1.5, Buyer shall not assume or be responsible for any 
liabilities or obligations of Seller or the Company.  Following the Closing, 
Seller shall perform, pay or discharge all liabilities and obligations 
relating to the Business, other than the Assumed Liabilities, that arose or 
relate to events occurring prior to the Closing, including (i) all claims 
relating to products sold or distributed by the Company prior to the Closing 
Date with the exception of warranty repairs in the ordinary course of 
business and (ii) all liabilities and obligations of Seller or the Company to 
employees, agents, representatives or similar persons under any oral or 
written agreement, arrangement, benefit plan, insurance policy or other 
program except as provided in the Transfer of Undertakings (Protection of 
Employment) Regulations 1981, as amended.  Other than the Assumed 
Liabilities, the Seller shall continue to be responsible for all debts 
payable by and claims outstanding against the Business at Closing or arising 
by reason of anything done or omitted to be done prior to Closing including 
all moneys, wages (including accrued holiday pay), taxes, rent and other 
expenses accrued as at Closing or in respect of any deed, matter, act or 
thing done or occurring up to that time, and, other than the Assumed 
Liabilities, this Agreement shall not operate to transfer to the Buyer or 
shall be construed as an acceptance by the Buyer or shall make the Buyer 
liable for any debts, liabilities or obligations in respect of any assets of 
the business not purchased by the Buyer or in respect or anything done or 
omitted to be done before Closing in the course of or in connection with the 
Business or otherwise in respect of any asset of the Business not transferred 
under this Agreement. All amounts payable or receivable in respect of the 
Business which are of a periodical nature including rents, rates, insurance 
premiums, petrol, gas, water, electricity and telephone charges, royalties 
and other outgoings or receipts relating to the Business shall (unless 
otherwise expressly agreed) be apportioned between the Seller and the Buyer 
as at Closing on the day to day basis.

Robin Williams is no longer employed by the Business.

     3.3  Employee Matters.  

          (a)  It is hereby agreed by the parties that this Agreement is 
governed by the Transfer of Undertakings (Protection of Employment)

the Regulations the contracts of employment of each of the persons employed 
by the Seller in the Business at Closing, being those whose names are set out 
in Schedule 4.2.3 ("Employee") shall have effect after Closing as if

Buyer will comply with and fulfill their respective obligations under the 
Regulations including (but not limited to) their obligations to provide 
information to and consult with all relevant trade union bodies (if any).

the Buyer, join with the Buyer in sending out a notice in a form agreed 
between them to the Employees confirming the transfer of their contracts of 
employment to the Buyer and stating that, save as to the identity of their 
employer (and save in respect of any occupational pension scheme rights) and 
such other amendments to which the Employees may expressly have agreed, all 
the terms of their employment shall remain the same.

          (d)  Subject to Section 3.3(e):

settlement of such Claim on behalf of and for the account and risk of the
Indemnifying Party, subject to the right of the Indemnifying Party to assume the
defense of such Claim at any time prior to settlement, compromise or final
determination thereof; and

          (c)  Anything in this Section 6.3 to the contrary notwithstanding, (i)

affect an Indemnified Party other than as a result of money damages or other
money payments, such Indemnified Party shall have the right, at its own cost and
expense, to defend, compromise or settle such Claim; provided, however, that if
such Claim is settled without the Indemnifying Party's consent (which consent
shall not be unreasonably withheld) such Indemnified Party shall be deemed to

damages arising out of such Claim, and (ii) such Indemnifying Party shall not,
without the written consent of such Indemnified Party, settle or compromise any
Claim or consent to the entry of any judgment that does not include as an
unconditional term thereof the giving by the claimant or the plaintiff to such
Indemnified Party a release from all liability in respect to such Claim.

                                       21

<PAGE>

to the extent that such information shall be shown to have been (a) previously
known by the party to which it was furnished, (b) in the public domain through

transactions contemplated by this Agreement.  Each party shall be deemed to have
satisfied its obligation to hold confidential information concerning or supplied
by the other party if it exercises the same care as it takes to preserve
confidentiality for its own similar information.

     7.2  Mail Received After Closing.  On and after the Closing, Buyer may
receive and open all mail addressed to Seller and deal with the contents thereof
in its sole discretion to the extent that such mail and contents relate to the

the Company and does not relate to the Assets, the Business or the Assumed
Liabilities.

     7.3  Competition.

Seller's confidential knowledge of the Business were disclosed to or utilized on
behalf of any person, firm, corporation or other business entity that is in
competition with Seller, and Seller agrees that it shall not, and shall use
commercially reasonable efforts to cause its Affiliates not to, at any time,
without the prior written consent of Buyer, disclose or use any such
confidential information.

          (b)  In furtherance of this Section 7.3 and to secure the interests of
Buyer hereunder, Seller agrees that for a period of two years following the
Closing Date, it shall not, in the United Kingdom, directly or indirectly,
participate in the ownership, management, operation or control of, or have any
financial interest in or aid or assist any person in the conduct of, any
business (a "Competitive Operation") that competes with the Business as
conducted by the Seller at any time or in the United Kingdom; provided, however,
that the Seller may acquire an entity that conducts a Competitive Operation
where such Competitive Operation accounts for less than 30% of the annual gross
revenues or net profits of the entity acquired and the Seller or any of its
affiliates may purchase products from a Competitive Operation where such
products are for internal use or are incidental to or are an incidental part of
products or a portfolio of products to be sold to customers of the Seller or to
customers of any Affiliates of Seller.

          (c)  If any provision of this Section 7.3 shall be held invalid, such
invalidity shall not affect any other provision of this Agreement not held so
invalid, and all other such provisions shall continue in full force and effect
to the full extent consistent with law.  If any such provision shall be held
invalid in part, such invalidity shall in no way affect the rest of such
provision which, together with all other provisions of this Agreement, shall
likewise continue in full force and effect to the full extent consistent with
law.

          (d)  Seller acknowledges that a violation by it or any of its
Affiliates of any of the covenants contained in this Section 7.3 may cause
immeasurable and serious damage to Buyer.  Seller accordingly acknowledges that

without posting a bond or other security, in addition to any other remedies
available to Buyer.

          (e)  The Seller further acknowledges and covenants with the Buyer that
it will not and it will 

                                       22

<PAGE>

procure that none of its Affiliates will for the period of two years following
Closing directly or indirectly solicit, interfere with or endeavour to entice
away from the Buyer any of the Employees (whether or not such person would
commit any breach of his contract of employment or engagement by reason of
leaving the service of the Buyer) nor shall it knowingly employ or aid or assist
in or procure the employment by any other person, firm or company or any such
person.

          (f)  The Seller further acknowledges and covenants with the Buyer that
Seller will not at any time following Closing use for any purpose the name
"Databit" or any name similar to it or likely to be confused with it (whether
alone or in conjunction with any such name).

and 7.3(f)  are reasonable and necessary for the protection of the legitimate
interests of the Buyer and that, having regard to those circumstances, those
covenants do not work harshly on it.

on the Business following Closing;

nor a supply of services for the purposes of value added tax;

Customs & Excise as required by paragraph 7 of Schedule I to the Value Added Tax
Act or by paragraph 4 of the Value Added Tax (General) Regulations 1985 or as
otherwise required by law;

          (d)  The Seller will on Completion deliver to the Buyer the records
referred to in Section 49 of the Value Added Tax Act 1994 and will not at any
time make a request to HM Customs & Excise for such records to be taken out of
the custody of the Buyer and the Buyer agree to preserve such records for such
period as may be required by law and during that period to permit the Seller to
inspect them in accordance with the terms of this agreement;

          (e)  Buyer declares that it is a taxable person for value added tax
purposes;

          (f)  The Seller hereby agrees to provide the Buyer within 30 days of a

the Buyer may require to enable the Buyer to establish the Seller's input tax 
recovery position in relation to the Assets under Part VA of the Value Added Tax
(General) Regulations 1985 as amended ("the VAT Regulations") up to Closing
(including details of the relevant values of taxable grants and supplies of
goods and services made or to be made to the Seller on or before Closing for or
in connection with the acquisition of any Asset and the amount of input tax
claimed by the Seller in the first and subsequent intervals under the VAT
Regulations) and to enable the Buyer to monitor the same and to make any
necessary adjustments under the VAT Regulations in relation to such input tax
after the date hereof and the Seller hereby warrants that to the best of its
knowledge and belief such information will, 

                                       23

<PAGE>

when it is provided, be true and accurate in all respects and hereby
acknowledges that the Buyer will rely upon such information in complying with
the VAT Regulations in respect of any future disposal, transfer, dealing or use
of the Assets; and

          (g)  If value added tax should be held to be chargeable on the sale
under this agreement or on any part of it then the Buyer agree that the value
added tax will be in addition to the Consideration and the Buyer will (against
delivery of proper tax invoices) pay the amount of any such value added tax.

     7.5  Directorship.  Until Buyer pays all of the principal amount of the
Note, and all accrued interest due thereunder, Buyer shall use commercially
reasonable efforts to cause one nominee, as selected by the Seller, to be
elected to, and to serve on, the Board of Directors of CTIG.  Seller hereby
selects William Driscoll as its initial nominee.

     7.6  Nominee Share.  Seller shall use its best efforts to cause the Nominee
Share to be transferred to the Buyer, at Seller's sole cost and expense, as soon
as practicable after Closing.

notice and during normal business hours, to the Books and Records of the

and Records of the Business not delivered to the Buyer pursuant to this

     FOR VALUE RECEIVED AND INTENDING TO BE LEGALLY BOUND HEREBY, CTI Data 
Solutions (International) Ltd. ("Borrower"), an English company and a 
wholly-owned subsidiary of CTI Group (Holdings), Inc. ("CTIG"), a Delaware

address or at such location as Lender may designate from time to time, the 
principal sum of Two Million Dollars ($2,000,000.00), together with interest 
as set forth below, until the date on which the principal amount is paid in 
full in accordance with the terms of this Promissory Note (the "Note").   

     Reference is made to that Asset Purchase Agreement, Security Agreement, 
Debenture and Pledge Agreement of even date herewith among Borrower, CTIG and

Capitalized terms appearing herein and not otherwise defined shall have the 
respective meanings given to such terms in the Asset Purchase Agreement, the 
Security Agreement and/or the Pledge Agreement.

     All outstanding principal and any accrued and unpaid interest thereon 
due hereunder shall be due and payable on February 2, 2001 (the "Maturity 
Date"). 

     1.  Interest.  During the period beginning on the date hereof and 
ending on the Maturity Date, interest shall accrue daily on the outstanding 
principal amount hereunder at a simple rate of ten percent (10%) per annum.  
Interest shall be calculated hereunder for the actual number of days that the 
principal is outstanding, based on a three hundred sixty (360) day year.  
Interest shall continue to accrue on the principal balance hereof at rate of 
interest specified in this Note, notwithstanding any demand for payment, 
acceleration and/or the entry of any judgment against Borrower, until all 
principal owing hereunder is paid in full.

principal payments shall be due on the Note until the Maturity Date.  Accrued 
interest shall be paid to the Lender quarterly in arrears on April 1, July 1,

     3.  Prepayments.  This Note may be prepaid in whole or in part at any 
time and from time to time without payment of a penalty or premium provided 
that each such prepayment is accompanied by interest on the amount of such 
prepayment calculated at the rate of interest set forth in this Note to the 
date of such prepayment.  The Borrower hereby agrees to cause CTIG to use 
commercially reasonable efforts to sell, within twelve (12) months of the 
date hereof, its United States telemanagement service bureau and to apply the 
net cash proceeds from such sale, up to an amount equal to the Required Cash 
Amount (as the term "Required Cash Amount" is defined in the Asset Purchase 
Agreement), toward reducing the principal amount outstanding under this Note. 
 The foregoing shall in no way limit the obligations of Borrower to repay 
principal and pay interest in accordance with the terms of this Note, which 
are absolute and unconditional.

     4.  Events of Default.  Each of the following shall be an "Event of 
Default" hereunder:  (1) the non-payment when due of any amount of principal 
or interest payable under this Note; or (2) if Borrower becomes insolvent or

by or against Borrower under any provision of any state or federal law or 
statute alleging that Borrower is insolvent or unable to pay debts as they 
mature or under any provision of the United States Bankruptcy Code, as 
amended.

     5.  Lender's Rights Upon Default.  Upon the occurrence of any Event of 
Default and without the necessity of giving any prior written notice to 
Borrower, Lender may do any one or all of the following: (a) accelerate the 
maturity of this Note and all amounts payable hereunder and demand immediate 
payment thereof and (b) exercise all of the rights, benefits, privileges and 
remedies of a secured party under the laws of the United Kingdom (or under 
the laws of any other jurisdiction in which any collateral security for the 
obligations of the Borrower under this Note may be located) and all of 
Lender's rights and remedies under the Security Agreement and/or the Pledge 
Agreement.

     6.  Guaranty.  Pursuant to the Guaranty of even date herewith of CTIG 
in favor of Lender, repayment of principal of and payment of interest in 
unconditionally guaranteed by CTIG.

     7.  Attorneys' Fees and Costs.  In the event that Lender engages an 
attorney to represent it in connection with (a) any default by Borrower under 
the Note, (b) the enforcement of any of Lender's rights and remedies under 
the Note, or (c) any bankruptcy or other insolvency proceedings commenced by 
or against Borrower, then Borrower shall be liable to and shall reimburse 
Lender for all reasonable attorneys' fees, costs and expenses incurred by 
Lender. Borrower shall also be liable and shall also reimburse Lender for all 
other costs and expenses incurred by Lender in connection with the 
collection, preservation and liquidation of any property acting as collateral 
security under the Note and/or in the enforcement of any of Borrower's

be held to be invalid or unenforceable, such invalidity or unenforceability

that any provision is invalid or incapable of being enforced, such provision

closely as possible in a permissible manner in order that the transactions 
contemplated hereby are consummated to the greatest extent possible.  The 
waiver of any Event of Default or the failure of Lender to exercise any right 
or remedy to which it may be entitled shall not be deemed a waiver of any 
subsequent Event of Default or of Lender's right to exercise that or any 
other right or remedy to which Lender is entitled.

     IN WITNESS WHEREOF, Borrower has duly executed this Note the day and 
year first above written and has hereunto set hand and seal.

<PAGE>

states or other jurisdictions where the nature and extent of the business 
transacted by it or the ownership of assets makes such qualification 
necessary, except for those jurisdictions in which the failure to so qualify 
would not have a material adverse effect on Guarantor's financial condition, 
results of operation or business or the rights of Secured Party in or to any 
of the Collateral;  

          4.2  The execution, delivery and performance of this Agreement, the 
Guaranty, the Pledge Agreement and the transactions contemplated hereunder 
and thereunder are all within Guarantor's corporate powers, have been duly 
authorized by Guarantor and will not violate any provision of any applicable 
law, rule or regulation, judgement, order, writ or decree, or of any 
contract, agreement, indenture or instrument to which Guarantor is a party or 
by which Guarantor or its assets (including the Collateral) are or may be 
bound; 

          4.3  This Agreement, the Guaranty, the Pledge Agreement, the 
Obligations and all related instruments, agreements and documents, when 
executed and/or delivered by Guarantor, will represent the legal, valid and 
binding Obligations of Guarantor, enforceable against Guarantor in accordance

or any of its assets are bound, and Guarantor is in compliance in all 
respects with all applicable provisions of laws, rules, regulations, 
licenses, permits, approvals and orders of any foreign, federal, state or 
local governmental authority, except to the extent such default, violation or 
non-compliance would not result in or cause a material adverse change in the 
assets, business or prospects of Guarantor, or have an adverse effect on the 
legality, validity or enforceability of this Agreement, the Guaranty or the 
Pledge Agreement or priority of the security interests or liens of Secured 
Party in the Collateral, or would impair the ability of Guarantor to perform 
its obligations under this Agreement or under any of the other financing 
agreements, or of Secured Party to enforce any Obligation or realize upon any 
Collateral;

          4.6  There are no judgments or judicial or administrative orders or

Collateral) of Guarantor, or the ability of Guarantor to perform its 
obligations under this Agreement, the Guaranty, the Pledge Agreement, the 
Obligations or any related instruments, agreements or documents;

purports to own, free from liens, claims and encumbrances of any third 
Person, except for Permitted Liens;

obligor upon such Collateral has or will have (as the case may be) capacity 
to contract;

          4.10 Each account receivable is or will be (as the case may be) a

Guarantor and file or record any such documents in such manner as Secured

Agreement.  Guarantor shall permit Secured Party or any other holder of the 
Note, its officers, employees, agents and representatives at any time and 
from time to time, to have full access to all of the Books and Records and 
any other records pertaining to Guarantor's business or the Collateral which 
Secured Party may request, and shall cause all Persons to make all such Books 
and Records in their possession available to Secured Party, its officers, 
employees, agents and representatives and, if deemed necessary by Secured 
Party, in its sole discretion, permit Secured Party, its officers, employees, 
agents and representatives to remove the Books and Records from Guarantor's 
place(s) of business or any other place where they may be found for the 
purpose of examining, auditing and/or reproducing the same.  Subject to the 
terms and conditions of this Agreement, any of Guarantor's Books and Records 
so removed by Secured Party, its officers, employees, agents or 
representatives, shall be returned to Guarantor as soon as Secured Party 
shall have completed its inspection, audit and/or reproduction thereof.  
Secured Party's right to take possession of the Books and Records shall be 
enforceable at law by an action of replevin or by any other appropriate 
remedy at law or in equity;

          5.4  Guarantor shall promptly pay, when due, all taxes, assessments 
and impositions upon the Collateral or for its use or operation or upon this

rate set forth in the Note, for any payment made, or any expense incurred by 
Secured Party, pursuant to the foregoing authorization;

          5.5  Guarantor shall upon reasonable notice during regular business 
hours allow Secured Party, by or through any of its officers, employees, 
agents or representatives, to examine or inspect the Collateral, wherever 
located;

          5.6  If any of the Collateral or any of the Books and Records are, 
at any time, to be located on premises leased by Guarantor or on premises 
owned by Guarantor subject to a mortgage or other lien, Guarantor shall 
obtain and deliver, or cause to be obtained and delivered to Secured Party, 
prior to delivery of any Collateral or Books and Records to such premises, an 
agreement, in form and substance satisfactory to Secured Party and its 
counsel, pursuant to which such landlord, mortgagee or other lien holder 
waives its rights, if any, to enforce any claims against Guarantor for monies 
due under a landlord's lien, mortgagee's mortgage or other lien by levy or 
distraint, or similar proceeding against the Collateral or the Books and 
Records, and assuring Secured Party's ability to have access to the 
Collateral and the Books and Records in order to exercise Secured Party's 
rights to take possession thereof and to remove the same from such premises 
and/or to prepare for disposition and dispose of the same at or about such 
premises;

          5.7  Guarantor shall promptly notify Secured Party, in writing, of 
(a) any event causing a material loss or decline in the value of the 
Collateral (whether or not covered by insurance) and of the amount of such 
loss or depreciation, (b) the inability or unwillingness of any Account 
Guarantor to pay or preserve the Collateral, and of any defense, set-off or 
counterclaim asserted by any Account Borrower, and (c) any Collateral having 
been returned by any Account Guarantor to Guarantor for any reason.  
Guarantor agrees not to return any Inventory to the supplier thereof, or to 
sell or otherwise dispose of Goods returned or repossessed from Secured 
Party, lessees or consignees thereof, without Secured Party's prior written 
consent;

          5.8  Guarantor shall, at its sole cost and expense, (a) preserve 
the Collateral and Guarantor's rights against any Person free and clear of 
all liens, claims and encumbrances, except for Permitted Liens and liens, 
claims and encumbrances created pursuant to this Agreement, (b) defend its 
right, title and interest in and to the Collateral and (c) defend the 
Collateral against any and all claims and demands of all Persons at any time 
or from time to time claiming the same or any interest therein.  Guarantor

security interest in and to the Collateral, nor allow any Person other than 
Secured Party to obtain a lien on or security interest in and to or levy upon 
the Collateral;

<PAGE>

          5.9  Guarantor shall, at its sole cost and expense, maintain the 
Collateral in good condition and repair at all times, subject to ordinary 
wear and tear, and shall not waste, abuse or destroy, or use in violation of 
any applicable laws, any of the Collateral; 

          5.10 Guarantor shall, at all times, maintain with financially sound 
and reputable insurers insurance with respect to the Collateral against loss 
or damage and all other insurance of the kinds and in the amounts customarily 
insured against or carried by corporations of established reputation engaged 
in the same or similar businesses and similarly situated.   Guarantor shall 
furnish such certificates, policies or endorsements to Secured Party as 
Secured Party shall require as proof of such insurance, and, if Guarantor 
fails to do so, Secured Party is authorized, but not required, to obtain such 
insurance at the expense of Guarantor.  All policies shall provide for at 
least thirty (30) days prior written notice to Secured Party of any 
cancellation or reduction of coverage and that Secured Party may act as 
attorney for Guarantor in obtaining, and at any time an Event of Default 
exists or has occurred and is continuing, adjusting, settling, amending and 
canceling such insurance.  Guarantor shall cause Secured Party to be named as 
a loss payee and an additional insured (but without any liability for any 
premiums) under such insurance policies and Guarantor shall obtain 
non-contributory loss payable endorsements to all insurance policies in form 
and substance satisfactory to Secured Party.  Such loss payable endorsements 
shall specify that the proceeds of such insurance shall be payable to Secured 
Party as its interest may appear and further specify that Secured Party shall 
be paid regardless of any act or omission by Guarantor or any of its 
affiliates.  At its option, Secured Party may apply any insurance proceeds 
received by Secured Party at any time to the cost of repairs or replacement 
of Collateral and/or to payment of the Obligations, whether or not then due, 
in any order and in such manner as Secured Party may determine or hold such 
proceeds as cash collateral for the Obligations;

          5.11 Guarantor will sell its Inventory only in the ordinary course 
of its business consistent with past practice; and  

          5.12 Guarantor shall, upon request of Secured Party or Secured 
Party itself may, in the name of Secured Party or Guarantor, and without 
notice to Guarantor, at any time or from time to time, notify Account 
Borrowers and other obligors of debts, liabilities and obligations to 
Guarantor that are included in the Collateral of Secured Party's interest in 
the Collateral pursuant to this Agreement and direct and cause all payments 
to be made to Secured Party with respect to such Collateral.  Secured Party 
shall have the right at any time and from time to time, in Secured Party's 
name or in the name of a nominee of Secured Party, to verify the validity, 
amount or any other matter relating to any Account or Collateral, by mail, 
telephone, facsimile transmission or otherwise.  Secured Party may demand, 
sue for, collect or receive any money or property payable or receivable on 
any Inventory.

          5.13 Guarantor shall join with the Secured Party at its request 
from time to time in executing financing statements, amendments thereto and 
continuation statements, and pay the cost of filing the same wherever the 
Secured Party reasonably deems desirable, and do, make, execute 

                                       8

<PAGE>

and deliver all additional and further acts, things, deeds, powers of 
attorney, assurances, writings and instruments that the Secured Party may 
reasonably require to vest completely in it and assure to it its rights 
hereunder and in and to the Collateral.

          5.14 Guarantor shall notify the Secured Party at least 30 days 
before changing its legal name, the location of its principal place of 
business or location where it keeps or holds any Collateral or any records 
relating thereto or before doing any business under any name other than its 
legal name.

          5.15 Guarantor shall use all commercially reasonable efforts to 
sell, within twelve (12) months of the date hereof, its United States 
telemanagement service bureau and to make available to Borrower and to cause 
Borrower to apply the net cash proceeds from such sale, up to an amount equal 
to the Required Cash Amount (as the term "Required Cash Amount" is defined in 
the Asset Purchase Agreement), toward reducing the principal amount

     SECTION 6.  SECURED PARTY'S RIGHTS UPON DEFAULT.

          Upon the occurrence of an Event of Default, the Obligations shall 
be immediately due and payable without notice or demand and Secured Party 
shall have, in addition to any and all rights and remedies that Secured Party 
may then have under the instruments, agreements and documents evidencing the 
Obligations, the UCC or at law or in equity, at its option, and without 
further action, the unconditional right to do any one or more of the 
following:

          6.1  Exercise any or all rights, remedies, benefits and privileges 
available to Secured Party under this Agreement, the Note, and those 
available to a secured party under the UCC, as well as those under any other 
applicable agreement with respect to any of the Collateral, and to apply such 
monies and the net Proceeds of the Collateral to any of the Obligations in 
such order as Secured Party, in its sole discretion, may elect;

          6.2  Require Guarantor to assemble all or part of the Collateral as 
Secured Party may in its sole discretion request or demand and make the same 
available to Secured Party in a place to be designated by Secured Party which 
is reasonably convenient to Secured Party and Guarantor;

          6.3  Without limiting the generality of the foregoing, Secured 
Party may immediately, without demand of performance and without other notice 
(except as specifically required by this Agreement or the Collateral 
Documents) or demand whatsoever to Guarantor, all of which are hereby 
expressly waived, and without advertisement, sell at public or private sale 
or otherwise realize upon, in Philadelphia, Pennsylvania or elsewhere, the 
whole or, from time to time, any part of the Collateral, or any interest 
which Guarantor may have therein, in one or more parcels at public sale or 
sales, at any exchange, broker's board or elsewhere, at such price and on 
such terms as

shall be reasonable notice of such sale or other disposition.  Guarantor 
agrees to assemble, or to cause to be assembled at its expense, the 
Collateral at such place or places as Secured Party shall designate.  At any 
such sale or other disposition, Secured Party may, to the extent permissible 
under applicable laws, purchase the whole or any part of the Collateral, free 
from any right or equity of redemption on the part of Guarantor, which right 
or equity is hereby waived and released.  

          6.4  The proceeds of any disposition of the Collateral or other 
action by Secured Party shall be applied as follows:
               
               (a)  First, the costs and expenses incurred in connection 
therewith or incidental thereto or to the care or safekeeping of any of the 
Collateral or in any way relating to the rights of Secured Party hereunder, 
including reasonable attorneys' fees and legal expenses;

               (b)  Second, to the satisfaction of the Obligations;

               (c)  Third, to the payment of any other amounts required by 
applicable law (including, without limitation, Section 9-504(a)(3) of the 
UCC); and

               (d)  Fourth, to Guarantor, to the extent of any surplus 
proceeds, absent the agreement of the parties to the contrary or as directed 
by a court of competent jurisdiction.

          6.5  Without limiting the generality of any of the rights and 
remedies conferred upon Secured Party under this paragraph, Secured Party 
may, to the full extent permitted by applicable laws:

               (a)  Enter upon the any of Guarantor's premises, exclude 
therefrom Guarantor, and take immediate possession of the Collateral, either 
personally or by means of a receiver appointed by a court of competent 
jurisdiction, using all necessary force to do so;

               (b)  At Secured Party's option, use, operate, manage and 
control the Collateral in any lawful manner;

               (c)  Exercise rights of set-off in accordance with applicable 
law; 

                                       10

<PAGE>

               (d)  Maintain, repair, renovate, alter, remove, abandon or 
relinquish rights in and to the Collateral as Secured Party may determine in 
its discretion;

               (e)  Cure any default in any reasonable manner and add the 
cost of any such cure to the Obligations and accrue interest thereon at the 
highest rate of interest then being charged to Guarantor on any of the 
Obligations;

               (f)  Notwithstanding any outstanding commitment of any Buyer 
to Guarantor to make additional and further loans, advances or extensions of 
credit to or for the benefit of Guarantor, declare any such commitment null 
and void and of no further force and effect whatsoever; and

               (g)  Retain all of Guarantor's Books and Records with respect 
to the Collateral.

     SECTION 7.  MISCELLANEOUS.

                          COLLATERAL PLEDGE AGREEMENT

     This Collateral Pledge Agreement (the "Agreement") is made this 2nd day 
of February, 1998, by CTI Group (Holdings), Inc., a Delaware corporation 
("Pledgor'), in favor of Siemens plc, an English company ("Pledgee"). 

                                  BACKGROUND

     Pursuant to a certain Asset Purchase Agreement of even date herewith 
between CTI Data Solutions (International) Ltd., an English company and a 
wholly-owned subsidiary of Pledgor ("Borrower") and Pledgee, Pledgee advanced 
a loan to Borrower in the principal amount of Two Million Dollars 
($2,000,000.00) (the "Term Loan").  The Term Loan is evidenced by a Secured 
Promissory Note of even date herewith executed and delivered by Borrower to 
Pledgee in the principal amount of Two Million Dollars  ($2,000,000.00) (the 
"Note").  As incentive for Pledgee to make the Term Loan to the Borrower, the 
Pledgor executed a Guaranty in favor of Pledgee relating to the performance 
of Borrower's obligations under the Note and entered into a Security 
Agreement of even date herewith granting Pledgee a security interest in 
substantially all of the assets of Pledgor.  Borrower's obligations to 
Pledgee, as evidenced by the Note are hereinafter referred to as the 
("Obligations").  

     As additional Collateral Security to the Obligations, Pledgor has agreed 
to pledge to Pledgee all of Pledgor's right, title and interest in and to the 
Pledged Securities (as hereinafter defined).  

     NOW, THEREFORE, in consideration of the foregoing, and intending to be 
legally bound hereby, and for good, valuable and sufficient consideration, 
the receipt of which is hereby acknowledged, Pledgor agrees as follows:

     7.   Certain Definitions.

          (a)  The term "Pledged Securities" shall mean all shares of Capital 
Stock of: (i) CTI Delaware Holdings, Inc., a Delaware corporation; (ii) CTI 
Soft-Com, Inc., a Delaware corporation; (iii) Plymouth Communications, Inc., 
a Delaware corporation; (iv) Telephone Budgeting Systems, Inc., a Delaware 
corporation; and (v) Borrower, owned legally or beneficially by Pledgor, 
including all shares issued in the future, whether certificated or 
uncertificated, together with all certificates, options, rights, dividends or 
other distributions issued in addition to, in substitution or in exchange 
for, or on account of, any such shares, and all cash and noncash proceeds of 
all of the foregoing, now or hereafter owned, acquired by or arising in favor 
of Pledgor.



<PAGE>

          (b)  The term "Event of Default" shall mean a default or an event 
of default under this Agreement, the Note or any other instrument, document 
or agreement, which evidences or secures the Obligations. 

     8.   Pledge.

          (a)  As security for the full and prompt satisfaction of the 
Obligations, Pledgor hereby pledges, hypothecates, delivers, transfers and 
sets over to Pledgee in form transferable for delivery, the Pledged 
Securities and grants to Pledgee a valid first priority lien on and security 
interest in and to the Pledged Securities, all certificates representing the 
Pledged Securities or other instruments or documents evidencing the same.

          (b)  Prior to the occurrence of an Event of Default, Pledgor shall 
be entitled to all voting rights with respect to the Pledged Securities and, 
for that purpose, Pledgee shall execute and deliver to Pledgor all necessary 
proxies. Immediately and without further notice, upon the occurrence of an 
Event of Default, whether or not the Pledged Securities shall have been 
registered in the name of Pledgee or its nominee, Pledgee or its nominee 
shall have the right to exercise all voting rights as to all of the Pledged 
Securities and all other corporate  rights and all conversion, exchange, 
subscription or other rights, privileges or options pertaining thereto as if 
Pledgee or its nominee were the absolute owner thereof including, without 
limitation, the right to exchange any or all of the Pledged Securities upon 
the merger, consolidation, reorganization, recapitalization or other 
readjustment of Pledgee thereof, or upon the exercise by Pledgee of any 
right, privilege, or option pertaining to any of the Pledged Securities and, 
in connection therewith, to deliver any of the Pledged Securities to any 
committee, depository, transfer agent, registrar or other designated agency 
upon such terms and conditions as it may determine, all without liability 
except to account for property actually received by Pledgee; but Pledgee 
shall have no duty to exercise any of the aforesaid rights or privileges, or 
may delay in so doing.

          (c)  Prior to the occurrence of an Event of Default, Pledgor shall 
be entitled to any and all regular cash dividends declared by the Pledgee to 
be paid on account of the Pledged Securities; provided, however, that 
immediately and without further notice, upon the occurrence of an Event of 
Default, whether or not the Pledged Securities shall have been registered in 
the name of Pledgee or its nominees, Pledgee or its nominee shall have the 
right to any and all regular cash dividends paid on account of the Pledged 
Securities which shall be delivered to Pledgee and may, at Pledgee's option, 
be applied on account of the Obligations in such order and manner as Pledgee 
may elect.

          (d)  At any time following execution of this Agreement, if Pledgor 
shall become entitled to receive or shall receive, in connection with any of 
the Pledged Securities, any: (i) stock certificate, including, without 
limitation, any certificate representing a stock dividend or in connection 
with any increase or reduction of capital, reclassification, merger, 
consolidation, sale of assets, combination of shares, stock split, spin-off 
or split-off; (ii) option, warrant or right, whether as an addition to or in 
substitution or in exchange for any of the Pledged Securities, or otherwise; 
or (iii) dividends or distributions payable in property, including securities 
issued by an issuer other than Pledgee; then, Pledgor shall accept the same 
as Pledgee's agent, in express trust for Pledgee, and shall deliver the same 
forthwith to the Pledgee in the exact form received with, as applicable, 
Pledgor's endorsement, or 


                                       2

<PAGE>

appropriate stock powers duly executed in blank, (with signatures "bank 
guaranteed") which the Pledgor hereby unconditionally agrees to make and/or 
furnish, to be held by Pledgee, subject to the terms hereof, as part of the 
Pledged Securities. 

          (e)  The Pledgor hereby delivers to the Pledgee appropriate updated 
stock transfer powers duly executed in blank for the Pledged Securities and 
will deliver appropriate updated stock transfers powers duly executed in 
blank for any Pledged Securities to be pledged hereunder from time to time.

     9.   Remedies Upon an Event of Default.

          (a)  Upon the occurrence of an Event of Default, Pledgee shall have 
in each case all of the remedies of a secured party under the Pennsylvania 
Uniform Commercial Code, and, without limiting the foregoing, shall have the 
right, without demand of performance or other demand, advertisement, or 
notice of any kind (except the notice specified below of time and place of 
public or private sale or other disposition) to or upon the Pledgor or any 
other person (all of which are, to the extent permitted by law, hereby 
expressly waived), to forthwith realize upon the Pledged Securities or any 
part thereof, and may forthwith, or agree to, sell or otherwise dispose of 
and deliver the Pledged Securities or any part thereof or interest therein, 
in one or more parcels at public or private sale or sales, at any exchange, 
broker's board or elsewhere, at such prices and on such terms (including, 
without limitation, a requirement that any purchaser of all or any part of 
the Pledged Securities purchase the shares constituting the Pledged 
Securities for investment and without any intention to make a distribution 
thereof) as Pledgee shall, in its sole discretion, determine (the Pledgor 
hereby waiving and releasing any and all right or equity of redemption 
whether before or after sale hereunder) for or on credit, or for future 
delivery without assumption of any credit risk, with the right to Pledgee or 
any purchaser to purchase upon any such sale or acquire pursuant to (i) above 
the whole or any part of the Pledged Securities free of any right or equity 
of redemption in Pledgor, which right or equity is hereby expressly waived 
and released.  Pledgee agrees to give at least ten (10) days written notice 
of the time and place of any public sale or of the time after which a private 
sale or other disposition may take place, which notice Pledgor hereby deems 
commercially reasonable.

          (b)  The proceeds of any disposition of the Pledged Securities or 
other action by Pledgee shall be applied as follows:

               (i)  First, the costs and expenses incurred in connection 
therewith or incidental thereto or to the care or safekeeping of any of the 
Pledged Securities or in any way relating to the rights of Pledgee hereunder, 
including reasonable attorneys' fees and legal expenses;

               (ii) Second, to the satisfaction of the Obligations;


                                       3

<PAGE>

              (iii) Third, to the payment of any other amounts required by 
applicable law (including, without limitation, Section 9-504(a)(3) of the 
Uniform Commercial Code as enacted in the Commonwealth of Pennsylvania (the 
"UCC"); and

               (iv) Fourth, to Pledgor, to the extent of any surplus 
proceeds, absent the agreement of the parties to the contrary or as a court 
of competent jurisdiction may direct.  

     10.  Pledgor's Representations and Warranties.  Pledgor represents and
warrants that:

          (a)  Pledgor has all requisite capacity and power to enter into 
this Pledge, to pledge the Pledged Securities for the purposes described in 
Paragraph 2(a) above, and to carry out the transactions contemplated by this 
Pledge;

          (b)  Pledgor is the legal and beneficial owner of the Pledged 
Securities free and clear of all liens, security interests and other 
encumbrances except the security interest granted hereby.  The Pledged 
Securities include all issued and outstanding capital stock of each issuer 
thereof.  All of the Pledged Securities have been duly authorized and validly 
issued and are fully paid and non-assessable and are subject to no option to 
purchase or similar rights of any person or entity.  Pledgor is not, and will 
not become, a party to or bound by any agreement which restricts in any 
manner the rights of any present or future holder of any of the Pledged 
Securities with respect thereto.;

          (c)  The execution and delivery of this Pledge, and the performance 
of its terms, will not violate or constitute a default under the terms of any 
agreement, indenture or other instrument, license, judgment, decree, order or 
regulation, applicable to Pledgor or any of its property; and

          (d)  Upon the execution of this Pledge and the delivery to Pledgee 
of the shares of Pledged Securities now held of record by Pledgor, this 
Pledge shall create a valid first priority lien upon and perfected security 
interest in the Pledged Securities and the cash and noncash proceeds thereof, 
subject to no prior lien or subordinate lien, or agreement purporting to 
grant to any third party a security interest in the property or assets of 
Pledgor which would include the Pledged Securities.

     11.  Pledgor's Covenants.  Pledgor hereby covenants that, until all of 
the Obligations have been satisfied in full:

          (a)  Pledgor will not sell, convey, or otherwise dispose of any of 
the Pledged Securities or any interest therein, or create, incur, or permit 
to exist any pledge, mortgage, lien, charge, encumbrance or any security 
interest whatsoever in or with respect to any of the Pledged Securities or 
the proceeds thereof, other than that created hereby; and 


                                       4

<PAGE>

          (b)  Pledgor will, at Pledgor's own expense, defend (engaging 
counsel acceptable to Pledgee) Pledgee's right, title, special property and 
security interest in and to the Pledged Securities against the claims of any 
person, firm, corporation or other entity.

     12.  Further Assurances.  Pledgor shall at any time, and from time to 
time, at its sole expense, upon written request of Pledgee, execute and 
deliver such further documents and do such further acts and things as Pledgee 
may reasonably request to effect the purposes of this Pledge including, 
without limitation, delivering to Pledgee, upon the occurrence of an Event of 
Default, irrevocable proxies with respect to the Pledged Securities in form 
satisfactory to Pledgee. Until receipt thereof, this Pledge shall constitute 
Pledgor's proxy to Pledgee or his nominee to vote all shares of Pledged 
Securities then registered in Pledgor's name.  To the extent permitted by 
law, Pledgor authorizes Pledgee to execute and file, in Pledgor's name or 
otherwise, Uniform Commercial Code financing statements (which may be copies 
of this Pledge) that the Pledgor in its sole discretion may deem necessary or 
appropriate to further perfect the security interest herein. 

     13.  Termination of Pledge.  Upon the satisfaction in full of all 
Obligations and the satisfaction of all additional costs and expenses of 
Pledgee as provided herein, this Pledge shall terminate and Pledgee shall 
deliver to Pledgor, the Pledged Securities or so much thereof as shall not 
have been sold or otherwise applied pursuant to this Pledge.

     14.  Miscellaneous.

          (a)  Beyond the exercise of reasonable care to assure the safe 
custody of the Pledged Securities while held hereunder, Pledgee shall have no 
duty or liability to preserve rights pertaining thereto and shall be relieved 
of all responsibility for the Pledged Securities upon surrendering the 
Pledged Securities or tendering surrender of it to Pledgor.

          (b)  The rights and remedies provided herein and in the Note and 
any related instruments, agreements and documents are cumulative and are in 
addition to and not exclusive of any rights or remedies provided by law, 
including, without limitation, the rights and remedies of a secured party 
under the UCC. 

          (c)  The provisions of this Pledge are severable, and if any clause 
or provision shall be held invalid or unenforceable in whole or in part in 
any jurisdiction and shall not in any manner affect such clause or provision 
in any other jurisdiction or any other clause or provision in this Pledge in 
any jurisdiction.

     15.  Notices.  All notices and other communications hereunder shall be 
in writing and shall be deemed to have been validly given, as of the date

  CTIG Closes Transaction to Acquire Databit Ltd.--A Subsidiary of Siemens plc

Merger Significantly increases CTIG's Revenues, Customer Base, Staff, 
International Presence


Valley Forge, Pennsylvania USA. CTI Group (Holdings) Inc. (OTC:CTIG), 
following a board meeting, announced today that it has successfully concluded
a transaction with Siemens plc of the U.K. to acquire Databit Ltd., a 
wholly-owned subsidiary of Siemens plc operating exclusively in 
telemanagement products and services. Databit now becomes a wholly-owned 
subsidiary of CTIG and will undergo a name change to CTI Data Solutions Ltd. 
to reflect market synergies with CTIG's major U.S. subsidiary CTI Data 
Solutions Inc.

     CTIG funded the transaction by the issuance to Siemens of a $2 million 
promissory note which will become due for repayment by February 2, 2001. The 
note carries interest at the rate of 10% per annum payable quarterly in 
arrears and is secured by a second lien on CTIG's assets, Mr. Bill Driscoll, 
Managing Director of Siemens plc, will join CTIG's board of directors.

     Based on historical financial information, the acquisition will 
dramatically increase CTIG's business. Assuming the acquisition had been 
effective from April 1, 1997, the fiscal year ending March 31, 1998 would 
show pro form annualized revenues increasing from approximately $3 million to 
approximately $8.3 million. The customer base will increase from 
approximately 4,500 North American sites to over 13,500 sites world-wide; and 
staff will increase from approximately 35 to 90 employees.

     CTIG's Chairman and CEO, Anthony P. Johns, said, "that by acquiring 
Databit CTIG adds important critical mass; strengthens its product portfolio; 
significantly expands its sales distribution channels; and enhances its 
ability to market products internationally; in particular, the ability to 
market and support its new telecommunications billing products overseas."

     Mr. Johns continued, saying that, "the businesses of CTIG's U.S. 
subsidiaries and Databit are totally complementary. Both recently introduced 
new, Year-2000 compliant, Windows OS products for sale into mature markets 
eager to replace obsolete DOS systems and into new markets emerging world-wide
from telecommunications industry deregulation. The companies have a 
non-overlapping market presence with respect to each other such that the 
merger will expand product offerings to each of the companies' existing 
customer bases."

     Said Mr. Johns, "We believe that Databit's high-end ClairePro 
(telemanagement) product for Windows NT-Registered Trademark- will gain an 
established network of new U.S. distributors within six months. 
Subsequently--we will be investing further in our NEPTUNE Billing System for 
Windows NT and utilizing fully the benefits of our newly established presence 
in the U.K."

     CTIG, through its wholly-owned subsidiaries, designs, develops, markets 
and supports information processing software and services for managing 
telecommunications systems. The Company provides telemanagement solutions to 
corporate users of telecommunications services, and billing solutions for 
providers of telecommunications services to invoice customers.

uncertainties. These statements may differ materially from actual future
