AMENDED AND RESTATED
ACQUISITION LOAN
PROMISSORY NOTE

$500,000.00		November 18, 2008 Indianapolis, Indiana

     1. Agreement to Pay. FOR VALUE RECEIVED, CTI GROUP (HOLDINGS), INC., a Delaware corporation (“Borrower”), hereby promises to pay to the order of NATIONAL CITY BANK, a national banking association, its successors and assigns (“Lender”), the principal sum of Five Hundred Thousand and No/100 Dollars ($500,000.00) (the “Loan”), or so much thereof as may be advanced pursuant to that certain Loan Agreement dated December 22, 2006 between Borrower and Lender (the “Loan Agreement”), as modified by that certain First Modification of Loan Documents dated November 13, 2007, and as further modified by that certain Second Modification of Loan Documents of even date herewith at the place and in the manner hereinafter provided, together with interest thereon at the rate or rates described below, and any and all other amounts which may be due and payable hereunder from time to time without relief from valuation or appraisement laws.

     2. Interest Rate. Interest shall accrue on the outstanding principal balance of this Note from the date hereof through the Acquisition Loan Maturity Date (as defined in the Loan Agreement) at the interest rate as set forth in the Loan Agreement.

     3. Payment Terms.

     3.1 Principal and Interest. Payments of principal and interest due under this Note, if not sooner declared to be due in accordance with the provisions hereof, shall be made as follows:

     (a) Payment of interest shall be made as set forth in the Loan Agreement.

     (b) The unpaid principal balance of this Note, if not sooner paid or declared to be due in accordance with the terms hereof or the terms of the Loan Agreement, together with all accrued and unpaid interest thereon and any other amounts due and payable hereunder or under any other Loan Document (as hereinafter defined), shall be due and payable in full at the Acquisition Loan Maturity Date.

     3.2 Application of Payments. Prior to the occurrence of an Event of Default, all payments and prepayments on account of the indebtedness evidenced by this Note shall be applied as follows: (a) first, to fees, expenses, costs and other similar amounts then due and payable to Lender, including, without limitation any prepayment premium, exit fee or late charges due hereunder, (b) second, to accrued and unpaid interest on the principal balance of this Note, (c) third, to the payment of principal due in the month in which the payment or prepayment is made, (d) fourth, to any escrows,

impounds or other amounts which may then be due and payable under the Loan Documents, (e) fifth, to any other amounts then due Lender hereunder or under any of the Loan Documents, and (f) last, to the unpaid principal balance of this Note. Any prepayment on account of the indebtedness evidenced by this Note shall not extend or postpone the due date or reduce the amount of any subsequent payment of principal or interest due hereunder. After an Event of Default has occurred and is continuing, payments may be applied by Lender to amounts owed hereunder and under the Loan Documents in such order as Lender shall determine, in its sole discretion.

     3.3 Method of Payments. All payments of principal and interest hereunder shall be paid by automatic debit, wire transfer, check or in coin or currency which, at the time or times of payment, is the legal tender for public and private debts in the United States of America and shall be made at such place as Lender or the legal holder or holders of this Note may from time to time appoint in the payment invoice or otherwise in writing, and in the absence of such appointment, then at the offices of Lender at One National City Center, Suite 200E, Indianapolis, Indiana 46255. Payment made by check shall be deemed paid on the date Lender receives such check; provided, however, that if such check is subsequently returned to Lender unpaid due to insufficient funds or otherwise, the payment shall not be deemed to have been made and shall continue to bear interest until collected. Notwithstanding the foregoing, the final payment due under this Note must be made by wire transfer or other final funds. If requested by Borrower, interest, principal payments and any fees and expenses owed Lender from time to time will be deducted by Lender automatically on the due date from Borrower’s account with Lender, as designated in writing by Borrower. Borrower will maintain sufficient funds in the account on the dates Lender enters debits authorized by this Note. If there are insufficient funds in the account on the date Lender enters any debit authorized by this Note, the debit will be reversed. Borrower may terminate this direct debit arrangement at any time by sending written notice to Lender at the address specified in the Loan Agreement.

     3.4 Late Charge. If any payment of interest or principal due hereunder is not made within ten (10) days after such payment is due in accordance with the terms hereof, then, in addition to the payment of the amount so due, Borrower shall pay to Lender a “late charge” of the greater of: (i) five cents for each whole dollar so overdue or (ii) Twenty-Five Dollars ($25.00) to defray part of the cost of collection and handling such late payment. Borrower agrees that the damages to be sustained by the holder hereof for the detriment caused by any late payment are extremely difficult and impractical to ascertain, and that the amount of five cents for each one dollar due is a reasonable estimate of such damages, does not constitute interest, and is not a penalty.

     4. Security. This Note is secured by (i) the Loan Agreement, (ii) the Guaranties (the "U.S. Guaranties”) dated December 22, 2006, and reaffirmed November 13, 2007, from CTI Data Solutions (USA) Inc., CTI Billing Solutions, Inc., CTI Delaware Holdings, Inc., Centillion Data Systems, L.L.C., CTI Data Solutions Ltd, CTI Group Ltd. (formerly CTI Billings Solutions Ltd) and CTI Billing Solutions Ltd (formerly Ryder Systems Ltd) to Lender, (iii) the Security Agreements (“U.S. Security Agreements”) dated December 22, 2006 from Borrower, CTI Data Solutions (USA) Inc., CTI Billing Solutions, Inc., CTI Delaware Holdings, Inc. and Centillion

Data Systems, L.L.C. to Lender, (iv) the Charge Over Shares In Ryder Systems Ltd from Ryder Systems Ltd to Lender dated December 22, 2006 (the “Charge Over Shares”), (v) the Debentures between the Borrower, CTI Data Solutions Ltd and Ryder Systems Ltd, and Lender dated December 22, 2006 (the “UK Debentures”), and (vi) the Guarantee and Indemnities between CTI Data Solutions Ltd and Ryder Systems Ltd, and Lender dated December 22, 2006 and reaffirmed on November 13, 2007 (the “UK Guarantees”) (the Loan Agreement, the U.S. Guaranties, the U.S. Security Agreements, the Charge Over Shares, the UK Debentures, the UK Guarantees and any other document now or hereafter given to evidence or secure payment of this Note or delivered to induce Lender to disburse the proceeds of the Loan, as such documents may hereafter be amended, restated or replaced from time to time, are hereinafter collectively referred to as the “Loan Documents”). Reference is hereby made to the Loan Documents (which are incorporated herein by reference as fully and with the same effect as if set forth herein at length) for a statement of the covenants and agreements contained therein, a statement of the rights, remedies, and security afforded thereby, and all matters therein contained.

     5. Events of Default. The occurrence of any “Event of Default” (after the expiration of any applicable notice and/or cure periods) under any of the Loan Documents shall constitute an “Event of Default” under this Note.

     6. Remedies. At the election of the holder hereof, and after written notice to Borrower, the principal balance remaining unpaid under this Note, and all unpaid interest accrued thereon and any other amounts due hereunder, shall be and become immediately due and payable in full upon the occurrence and during the continuance of any Event of Default. Failure to exercise this option shall not constitute a waiver of the right to exercise same in the event of any subsequent Event of Default. No holder hereof shall, by any act of omission or commission, be deemed to waive any of its rights, remedies or powers hereunder or otherwise unless such waiver is in writing and signed by the holder hereof, and then only to the extent specifically set forth therein. The rights, remedies and powers of the holder hereof, as provided in this Note, the Loan Agreement and in all of the other Loan Documents are cumulative and concurrent, and may be pursued singly, successively or together against Borrower, any guarantor thereof, the security given at any time to secure the repayment hereof, all at the sole discretion of the holder hereof. If any suit or action is instituted or attorneys are employed to collect this Note or any part hereof, Borrower promises and agrees to pay all costs of collection, including reasonable attorneys’ fees and court costs.

     7. Covenants and Waivers. Borrower and all others who now or may at any time become liable for all or any part of the obligations evidenced hereby, expressly agree hereby to be jointly and severally bound, and jointly and severally: (i) waive and renounce any and all homestead, redemption and exemption rights and the benefit of all valuation and appraisement privileges against the indebtedness evidenced by this Note or by any extension or renewal hereof; (ii) waive presentment and demand for payment, notices of nonpayment and of dishonor, protest of dishonor, and notice of protest; (iii) waive any and all notices in connection with the delivery and acceptance hereof and all other notices in connection with the performance, default, or enforcement of the payment hereof or hereunder; (iv) waive any and all lack of diligence and delays in the enforcement of the payment hereof; (v) agree that the liability of Borrower, guarantor, endorser or obligor shall be unconditional and without regard to the liability of any other person or entity for the payment hereof, and shall not in any manner be affected by any

indulgence or forbearance granted or consented to by Lender to any of them with respect hereto; (vi) consent to any and all extensions of time, renewals, waivers, or modifications that may be granted by Lender with respect to the payment or other provisions hereof, and to the release of any security at any time given for the payment hereof, or any part thereof, with or without substitution, and to the release of any person or entity liable for the payment hereof; and (vii) consent to the addition of any and all other makers, endorsers, guarantors, and other obligors for the payment hereof, and to the acceptance of any and all other security for the payment hereof, and agree that the addition of any such makers, endorsers, guarantors or other obligors, or security shall not affect the liability of Borrower, any guarantor and all others now liable for all or any part of the obligations evidenced hereby. This provision is a material inducement for Lender making the Loan to Borrower.

Notwithstanding the foregoing, however, Lender may at any time and from time to time elect by notice in writing to Borrower to reduce or limit the collection to such sums which, when added to the said first-stated interest, shall not result in any payments toward principal in accordance with the requirements of the preceding sentence.
