ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS

     Pursuant to the Agreement and Plan of Merger, dated January 18, 2003 as
amended on February 27, 2003 and February 28, 2003 (the "Merger Agreement"), by
and among Itron, Inc. ("Itron"), Shadow Combination, Inc., a Delaware
Corporation and wholly owned subsidiary of Itron ("Shadow Combination"), and
Silicon Energy Corp., a Delaware Corporation ("Silicon"), the merger of Shadow
Combination with and into Silicon became effective March 4, 2003 (the
"Acquisition"). As a result of the Acquisition, Silicon became a wholly owned
subsidiary of Itron.

     In accordance with the Merger Agreement the capital stock of Shadow
Combination and the capital stock of Silicon, other than dissenting shares, were
cancelled and converted as follows:

          (a)   all issued and outstanding shares of capital stock of Shadow
Combination were converted into and became one fully paid and nonassessable
share of common stock, par value $.001 per share, of Silicon;

          (b)   all issued and outstanding shares of Silicon common stock
(including Silicon Series A and Series B Preferred Stock as converted) were
converted into the right to receive an amount of cash equal to approximately
$1.21 per share, a portion of which will remain in escrow as discussed below;

          (c)   all issued and outstanding shares of Silicon Series C Preferred
Stock were converted into the right to receive an amount of cash equal to
approximately $2.77 per share, a portion of which will remain in escrow as
discussed below; and

          (d)   all issued and outstanding shares of Silicon Series D Preferred
Stock were converted into the right to receive an amount of cash equal to
approximately $8.12 per share, a portion of which will remain in escrow as
discussed below.

     The consideration for the Acquisition was cash of $71,200,000, which
included the repayment of approximately $4,200,000 in convertible debt of
Silicon. Approximately $6,462,543 of the $71,200,000 will be held in escrow as
security for indemnification obligations to Itron against certain claims during
the first 24 months following the Acquisition.

     The foregoing summary is qualified in its entirety by reference to the full
text of the Merger Agreement attached hereto as Exhibit 2.1, which is
incorporated herein by reference.

     On March 4, 2003 Itron issued a press release announcing the Acquisition.
The press release is attached hereto as Exhibit 99.1 and is incorporated herein
by reference.

     Silicon uses its assets (including plant, equipment or other physical
property) to provide software solutions to customers including an integrated
data collection, warehousing and analytic platform for the management of energy
consumption information for utilities and major energy consumers. Itron intends
that Silicon will continue to use assets for the same purposes following the
Acquisition.

Credit Agreement (the "Credit Agreement") with Wells Fargo Bank, National
Association as Administrative Agent and the lenders who are, or may from time to
