Item 2. Acquisition or Disposition of Assets.

On January 21, 2003, we sold our optoelectronic components business that
provides cable television transmission systems, or CATV, telecom access and
satellite communications components to EMCORE Corporation for $25 million in
cash. The transaction includes the assets, products, product warranty
liabilities, technology and intellectual property related to this business. The
amount of consideration was determined through arms-length negotiations between
the parties.

This transaction, in conjunction with the sale of a substantial portion of our
optoelectronic components business to TriQuint Semiconductor, Inc. on January 2,
2003, completes the exit of our optoelectronic operations.

Item 7. Financial Statements, Pro Forma Financial Information and Exhibits.

(b) Pro Forma Financial Information.

The unaudited pro forma condensed statements of operations, included in Exhibit
99.1 to our Form 8-K filed on January 17, 2003, include adjustments to our
historical results for the operations of the business sold to EMCORE, as if the
sale had occurred at the beginning of the earliest fiscal year presented. The
adjustments for the operations of the business sold to EMCORE are reflected in
the column labeled "CATV Held-for-Sale." These unaudited pro forma condensed
statements of operations also include adjustments to reflect the sale to
TriQuint, as well as a refinement of our allocation methodology for shared
information technology costs.

The assets and liabilities sold to EMCORE consist of $7 million in inventory and
$2 million of other current liabilities related to product warranties at
September 30, 2002. We realized net proceeds of $24 million from the sale. In a
pro forma balance sheet the above adjustments would also result in an increase
to equity of $19 million.

You should read this Form 8-K in conjunction with our Form 8-K filed on January
17, 2003, including the unaudited pro forma condensed financial statements
contained therein, and our consolidated and combined financial statements
included in our Form 10-K for the year ended September 30, 2002. Management
believes that the assumptions used provide a reasonable basis on which to
present the unaudited pro forma condensed financial statements. They should not
be construed to be indicative of our results of operations or financial position
had the transactions and events described been consummated on the dates assumed.
These unaudited pro forma condensed financial statements also do not project our
results of operations or financial position for any future period or date.

(c) Exhibits.
