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.

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.
