    Certain statements contained in this press release regarding RHD's
future operating results or performance or business plans or prospects
and any other statements not constituting historical fact are
"forward-looking statements" subject to the safe harbor created by the
Private Securities Litigation Reform Act of 1995. Where possible, the
words "believe," "expect," "anticipate," "intend," "should," "will,"
"planned," "estimated," "potential," "goal," "outlook," and similar
expressions, as they relate to RHD or its management, have been used
to identify such forward-looking statements. All forward-looking
statements reflect only RHD's and Dex's current beliefs and
assumptions with respect to future business plans, prospects,
decisions and results, and are based on information currently
available to RHD and Dex. Accordingly, the statements are subject to
significant risks, uncertainties and contingencies which could cause
RHD's actual operating results, performance or business plans or
prospects to differ materially from those expressed in, or implied by,
these statements. Such risks, uncertainties and contingencies include,
but are not limited to, statements about the benefits of the merger
between RHD and Dex, including future financial and operating results,
RHD's plans, objectives, expectations and intentions and other
statements that are not historical facts.
    The following factors, among others, could cause actual results to
differ from those set forth in the forward-looking statements: (1) the
ability to obtain governmental approvals of the merger on the proposed
terms and schedule; (2) the failure of RHD and Dex stockholders to
approve the merger; (3) the risk that the businesses will not be
integrated successfully; (4) the risk that the cost savings and any
revenue synergies from the merger may not be fully realized or may
take longer to realize than expected; (5) disruption from the merger
making it more difficult to maintain relationships with customers,
employees or suppliers; and (6) general economic conditions and
consumer sentiment in our markets. Additional factors that could cause
RHD's and Dex's results to differ materially from those described in
the forward-looking statements are described in detail in the
Management's Discussion and Analysis of Financial Condition and
Results of Operations in RHD's and Dex's Annual Reports on Form 10-K
for the year ended December 31, 2004, as well as RHD's and Dex's other
