Exhibit 99



                             CAUTIONARY STATEMENTS


From time to time, the company may publish, verbally or in written form, 
forward-looking statements relating to such matters as anticipated financial
performance, business prospects, technological developments, new products,
research and development activities and similar matters. In fact, this Form 10-Q
(or any other periodic reporting documents required by the 1934 Act) may contain
forward-looking statements reflecting the current views of the company
concerning potential future events or developments. The Private Securities
Litigation Reform Act of 1995 (the "Act") provides a "safe harbor" for forward-
looking statements. These Cautionary Statements are being made pursuant to the
provisions of the Act and with the intention of obtaining the benefits of the
"safe harbor" provisions of the Act. In order to comply with the terms of the
"safe harbor," the company cautions investors that any forward-looking
statements made by the company are not guarantees of future performance and that
a variety of factors could cause the company's actual results and experience to
differ materially from the anticipated results or other expectations expressed
in the company's forward-looking statements. The risks and uncertainties which
may affect the operations, performance, development and results of the company's
business include, but are not limited to, the following: uncertainties relating
to the development and ownership of intellectual property; uncertainties
relating to the ability of the company and other companies to enforce their
intellectual property rights; uncertainties relating to economic conditions;
uncertainties relating to government and regulatory policies; uncertainties
relating to customer plans and commitments; the company's dependence on the
cable television industry and cable television spending; signal security; the
pricing and availability of equipment, materials and inventories; technological
developments; performance issues with key suppliers and subcontractors;
governmental export and import policies; global trade policies; worldwide
political stability and economic growth; regulatory uncertainties; delays in
testing of new products; rapid technology changes; the highly competitive
environment in which the company operates; the entry of new, well-capitalized
competitors into the company's markets; changes in the financial markets
relating to the company's capital structure and cost of capital; and
uncertainties inherent in international operations and foreign currency
fluctuations. The words "believe," "expect," "anticipate," "project," "plan" and
similar expressions identify forward-looking statements. Readers are cautioned
not to place undue reliance on these forward-looking statements, which speak
only as of the date the statement was made.
