NOTE 9 - SEGMENT REPORTING

Operating segments are defined as components of an enterprise that engage in
business activities for which separate financial information is available and
evaluated by the chief operating decision maker. Prior to the acquisition of the
DiviCom business, Harmonic was organized as one operating segment. On May 3,
2000, Harmonic completed the acquisition of the DiviCom business, thus changing
its organizational structure. The merged company has been organized into two
operating segments: Broadband Access Networks ("BAN") for fiber optic systems,
and Convergent Systems ("CS") for digital headend systems. These segments do not
correspond to the pre-merger companies in significant ways. For example,
Harmonic's TRANsend and CyberStream product lines are part of the CS segment.
Each of these operating segments require their own development and marketing
strategies and therefore have separate management teams, however, a worldwide
sales, sales support and systems integration group supports both operating
segments.

The results of the reportable segments are derived directly from the Company's
management reporting system. These results reported below are based on
Harmonic's method of internal reporting and are not necessarily in conformity
with generally accepted accounting principles. Subsequent to the acquisition of
DiviCom, management commenced measuring the performance of each segment based on
several metrics, including revenue, and income or loss from operations. These
results are used, in part, to evaluate the performance of, and allocate
resources to each of the segments. Revenue for the prior periods has been
reclassified to reflect the new organizational structure. The reclassified
revenue for the prior periods reflects only Harmonic's revenue, and not the
historical revenue of the DiviCom business. However, income or loss from
operations is not available and is impractical to prepare for the periods prior
to the quarter ended June 30, 2000, and accordingly, has not been presented. Net
income or loss, and assets and liabilities are not internally reported by
business segment.
