ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby supplemented as follows:

On October 30, 2013, CTI Group (Holdings) Inc.

Under the Note, the Issuer may, from the date of the Note through and including the Maturity Date (as defined below), request that the Lenders make one or more advances under the Note (each, an “Advance”). The Lenders may, in their sole and absolute discretion, elect to make or decline to make any Advance requested by the Issuer under the Note.

Pursuant to the Note, the Issuer promises to pay to the Lenders, on demand made at any time following April 30, 2014, or if demand is not sooner made, on May 31, 2014 (such date, or if earlier, the date demand is made under the Note, the “Maturity Date”), the unpaid balance under the Note plus all interest accrued thereunder as of the Maturity Date in the following proportions: 10% to the Reporting Person, 80% to Fairford Holdings, Ltd. and 10% to Michael Reinarts.

Interest under the Note accrues at a fixed rate per annum equal to 6.50%. Under the Note, on December 31, 2013, the Issuer will pay to the Lenders all interest accrued under the Note as of such date.

As collateral for the Issuer’s satisfaction of its obligations under the Note, the Issuer pledges to the Lenders a purchase money lien in all accounts, any receivables, inventory, machinery, equipment, supplies, general intangibles, furniture and fixtures purchased with any Advances under the Note.

The Note may be prepaid in full or in part at any time without premium or penalty.

On October 30, 2013, the Issuer requested an Advance of $700,000 under the Note, and the Lenders elected to make such Advance to the Issuer.
