        The accompanying notes are an integral part of these condensed
                      consolidated financial statements.

                              ECHELON CORPORATION
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)

1.   Basis of Presentation:

       The condensed consolidated financial statements include the accounts of
Echelon Corporation (the "Company"), a Delaware corporation, and its wholly
owned subsidiaries. Significant intercompany accounts and transactions have been
eliminated.

       While the financial information furnished is unaudited, the condensed
consolidated financial statements included in this report reflect all
adjustments (consisting only of normal recurring adjustments) which the Company
considers necessary for the fair presentation of the results of operations for
the interim periods covered and of the financial condition of the Company at the
date of the interim balance sheet. The results for interim periods are not
necessarily indicative of the results for the entire year. The condensed
consolidated financial statements should be read in conjunction with the Echelon
Corporation consolidated financial statements for the year ended December 31,
2000 included in its Form 10-K.

2.   Summary of Significant Accounting Policies:

       Use of Estimates in the Preparation of Financial Statements

       The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

       Revenue Recognition and Product Warranty

       The Company's revenues are derived from the sale and license of its
products and to a lesser extent, from fees associated with training and
technical support offered to its customers. Product revenues consist of revenues
from hardware sales and software licensing arrangements. Revenues from software
licensing arrangements accounted for 11.5% of total revenues for the quarter
ended March 31, 2001 and 8.2% for the same period in 2000. Service revenues
consist of product support (including software post-contract support services)
and training.

     The Company recognizes revenue when persuasive evidence of an arrangement
exists, delivery has occurred, the sales price is fixed or determinable,
collectibility is probable and there are no post-delivery obligations. For
hardware sales, including sales to distributors, these criteria are generally
met at the time of shipment to the customer. For software licenses, these
criteria are generally met upon shipment to the final end-user. The Company
provides limited post-contract customer support (PCS), consisting primarily of
technical support and "bug" fixes. In accordance with Statement of Position
(SOP) 97-2, "Software Revenue Recognition", revenue earned on software
arrangements involving multiple elements is allocated to each element based upon
the relative fair values of the elements. Revenue for the software license
element is recognized at the time of delivery of the application product to the
end-user. The Company uses the residual method to recognize revenue when a
license agreement includes one or more elements to be delivered at a future date
if evidence of the fair value of all undelivered elements exists. If an
undelivered element of the arrangement exists under the license arrangement,
revenue is deferred based on vendor-specific objective evidence of the fair
value of the undelivered element. If vendor-specific objective evidence of fair
value does not exist for all undelivered elements, all revenue is deferred until
sufficient evidence exists or all elements have been delivered. Revenue for the
PCS element, the total amount of which is determined from the stand-alone price
of providing this service, is recognized over the service period. The costs of
providing these services are expensed when incurred. Estimated reserves for
warranty costs as well as reserves for sales returns and allowances related to
anticipated return of products sold to distributors with limited rights of
return, which are not material to the consolidated financial statements, are
recorded at the time of shipment. The Company generally has not had any
significant post-delivery obligations associated with the sale of its products.
Service revenue is recognized as the training services are performed, or ratably
over the term of the support period.

       Cash, Cash Equivalents and Short-Term Investments

     The Company considers bank deposits, money market investments and all debt
and equity securities with an original maturity of three months or less as cash
and cash equivalents. The Company classifies its investments in debt and equity
securities as available-for-sale in accordance with Statement of Financial
Accounting Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt
and Equity Securities." As of March 31, 2001, the Company's available-for-sale
securities had contractual maturities from five to twenty-four months and an
average maturity of thirteen months. The fair value of available-for-sale
securities was determined based on quoted market prices at the reporting date
for those instruments. As of March 31, 2001, the amortized cost basis, aggregate
fair value and gross unrealized holding losses by major security type were as
follows (in thousands):



                                                                                              Unrealized

       Computation of Net Income/(Loss) Per Share

     Net income/(loss) per share has been calculated under SFAS No. 128,
"Earnings per Share." SFAS No. 128 requires companies to compute earnings per
share under two different methods (basic and diluted). Basic net income/(loss)
per share is calculated by dividing net income/(loss) by the weighted average
shares of common stock outstanding during the period. Diluted net income/(loss)
per share is calculated by adjusting the weighted average number of outstanding
shares assuming conversion of all potentially dilutive stock options and
warrants under the treasury stock method.

     The following is a reconciliation of the numerators and denominators of the
basic and diluted net income per share computations for the quarter ended March
31, 2001 (in thousands):

    Shares used in diluted computation........................       40,916
                                                                 ==========

    Basic.....................................................   $     0.00
                                                                 ==========

     For the quarter ended March 31, 2001, 1,890,179 stock options were not
included in the computation of diluted earnings per share because the options'
exercise price was greater than the average market price of the common shares
and therefore, the effect would be anti-dilutive.

                                       7


     For the quarter ended March 31, 2000, no diluted net loss per share
calculation was performed as the inclusion of potentially dilutive stock options
and warrants of 5,101,628 would be anti-dilutive.

       New Accounting Standards

     In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133," which amends SFAS No. 133 to be
effective for all fiscal years beginning after June 15, 2000. SFAS No. 133
establishes accounting and reporting standards requiring that every derivative
instrument be recorded in the balance sheet as either an asset or liability
measured at its fair value. The statement also requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. The Company does not currently engage in any
hedging activities and does not hold any derivative instruments. Accordingly,
there was no impact on the Company's financial position, results of operations
or cash flows on the adoption of SFAS 133 in the quarter ended March 31, 2001.

     In the fourth quarter of 2000, we adopted Staff Accounting Bulletin No.
101, "Revenue Recognition in Financial Statements," as amended ("SAB 101"),
issued by the Securities and Exchange Commission in December 1999. SAB 101
provides guidance on applying generally accepted accounting principles to
revenue recognition issues in financial statements. The adoption of SAB 101 did
not result in a change to the method of accounting for revenue nor did it have a
material effect on our financial position or results of operations or the
quarterly results during 2000.

3. Inventories:

     Inventories are stated at the lower of cost (first-in, first-out) or market

5. Segment Disclosure:

     In 1998, the Company adopted SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." Operating segments are defined as
components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in assessing business performance. The
Company's chief operating decision-making group is the Executive Staff, which is
comprised of the Chief Executive Officer and the Vice Presidents. SFAS No. 131
also requires disclosures about products and services, geographic areas and
major customers. The adoption of SFAS No. 131 did not affect results of
operations or the financial position of the Company but did affect the
disclosure of segment information.

     The Company operates in one principal industry segment: the design,
manufacture and sale of products for the controls network industry, and markets
its products primarily to the building automation, industrial automation,
transportation, and utility/home automation markets. The Company's products are
marketed under the LONWORKS(R) brand name, which provides the infrastructure,
and support required to implement and deploy open, interoperable, control
network solutions. All of the Company's products either incorporate or operate
with the Neuron(R) Chip and/or the LONWORKS protocol. The Company also provides
services to customers which consist of technical support and training courses
covering its LONWORKS network technology and products. The Company offers about
90 products and services that together constitute the LONWORKS system. Any given
customer purchases a small subset of such products and services that are
appropriate for that customer's application.

     The Company manages its business primarily on a geographic basis. The
Company's geographic areas are comprised of the Americas, Europe, Middle East
and Africa ("EMEA") and Asia Pacific/ Japan ("APJ"). Each geographic area
provides products and services as further described in Note 1. The Company
evaluates the performance of its geographic areas based on profit or loss from
operations. Profit or loss for each geographic area includes sales and marketing
expenses and other charges directly attributable to the area and excludes
certain expenses that are managed outside the geographic area. Costs excluded
from area profit or loss primarily consist of unallocated corporate expenses,
comprised of product development costs, corporate marketing costs and other
general and administrative expenses, which are separately managed. The Company
has no long-lived assets, other than property and equipment, goodwill, and loans
to certain key employees. Long-lived assets are attributed to geographic areas
based on the country where the assets are located. As of March 31, 2001 and
December 31, 2000, long-lived assets of about $4.5million and $4.1million,
respectively, were domiciled in the United States. Long-lived assets for all
other locations are not material to the consolidated financial statements.
Assets and the related depreciation and amortization are not being reported by
geography because the information is not reviewed by the Executive Staff to make
decisions about resources to be allocated to the geographic areas based on their
performance.

     In North America, the Company sells its products through a direct sales
organization. Outside the United States, direct sales, applications engineering
and customer support are conducted through the Company's operations in Europe,
Japan and China. Revenues are attributed to geographic areas based on the
country where the customer is domiciled. Summary information by geography for
the quarter ended March 31, 2001 and 2000 is as follows (in thousands):

       One customer, the sole independent distributor of the Company's products
in Europe, accounted for 30.1% of total revenues for the quarter ended March 31,
2001 and 27.3% for the same period in 2000.

6. Income Taxes:

     The provision for income taxes for the quarter ended March 31, 2001
includes a provision for Federal, state and foreign taxes based on the annual
estimated effective tax rate applied to the Company and its subsidiaries for the
year. The difference between the statutory rate and the Company's effective tax
rate is primarily due to the impact of foreign taxes and the beneficial impact
of deferred taxes resulting from the utilization of net operating losses. Income
taxes for the quarter ended March 31, 2000 primarily consist of taxes related to
profitable foreign subsidiaries and various state minimum taxes.

7. Related Party:

     In June 2000, the Company entered into a stock purchase agreement with ENEL
S.p.A., an Italian utility company ("ENEL"). At the same time, the Company also
entered into a research and development agreement with an affiliate of ENEL.
Under the terms of the R&D agreement, the Company will cooperate with ENEL to
integrate LONWORKS technology into ENEL's remote metering management project in
Italy. For the quarter ended March 31, 2001, the Company has recognized
approximately $218,000 of revenue related to the R&D agreement which is included
in Accounts Receivable at March 31, 2001.

8. Acquisition:

     On February 7, 2001, the Company acquired all of the outstanding capital
stock of ARIGO Software GmbH ("ARIGO"), a Beckum, Germany based developer of
LONWORKS hardware and software products. The Company paid cash for the
acquisition and has accounted for it using the purchase method of accounting.
Accordingly, results of operations for ARIGO have been included with those of
the Company since the date of acquisition.

Item 2.   Management's Discussion and Analysis of Financial Condition and
Results of Operations

     The following management's discussion and analysis of financial condition
and results of operations should be read in conjunction with management's
discussion and analysis of financial condition and results of operations
included in our Form 10-K for the year ended December 31, 2000.

Overview

     We develop, market and support a family of hardware and software products
and services that enables original equipment manufacturers, or OEMs, and systems
integrators to design and implement open, interoperable, distributed control
networks. We offer our products and services to OEMs and systems integrators in
the building, industrial, transportation, utility/home and other automation
markets. We provide a variety of technical training courses related to our
products and underlying technology. We also provide customer support on a per-
incident or annual contract basis.

     We market our products and services in North America, Europe, Japan, South
America and selected Asia-Pacific countries through a direct sales organization
augmented with the use of third-party distributors and systems integrators.
International sales, which include both export sales and sales by international
subsidiaries, accounted for 67.4% of our total revenues for the first quarter of
2001 and 62.4% for the same period in 2000. The percentage of our revenues
denominated in currencies other than the U.S. dollar, principally the Japanese
yen, was 6.9% for the first quarter of 2001 and 10.3% for the same period in
2000. However, this percentage may increase over time as we respond to market
requirements to sell our products and services in local currencies, such as the
Euro. As a result, our operations and the market price of our products may be
directly affected by economic and political conditions in the countries where we
do business. We expect that international sales will continue to constitute a
significant portion of total revenues.

     We derive our revenues primarily from the sale and licensing of our
products and, to a lesser extent, from fees associated with training and
technical support offered to our customers. Our product revenues consist of
revenues from sales of transceivers, control modules, routers, network interface
devices and development tools and from licenses of network services software
products. Revenues from software licensing arrangements accounted for 11.5% of
total revenues for the quarter ended March 31, 2001 and 8.2% for the same period
in 2000. Our service revenues consist of product support (including software
post-contract support services) and training. We recognize revenue when
persuasive evidence of an arrangement exists, delivery has occurred, the sales
price is fixed or determinable, collectibility is probable and there are no
post-delivery obligations. For hardware sales, including sales to distributors,
these criteria are generally met at the time of shipment to the customer. For
software sales, these criteria are generally met upon shipment to the final end-
user. The Company uses the residual method to recognize revenue when a license
agreement includes one or more elements to be delivered at a future date if
evidence of the fair value of all undelivered elements exists. If an undelivered
element of the arrangement exists under the license arrangement, revenue is
deferred based on vendor-specific objective evidence of the fair value of the
undelivered element. If vendor-specific objective evidence of fair value does
not exist for all undelivered elements, all revenue is deferred until sufficient
evidence exists or all elements have been delivered. We record estimated
reserves for warranty costs as well as for sales returns and allowances related
to anticipated return of products sold to distributors with limited rights of
return, at the time we sell the products. We generally have not had any
significant post-delivery obligations associated with the sale of our products.
We recognize service revenues as we perform the services, or ratably over the
term of the support period.

     Although we generated a profit, in the amount of $22,000, for the first
quarter of 2001 and for the third consecutive quarter, we have incurred net
losses in all other periods since our inception. We may not be able to sustain
this profitability on a quarterly or annual basis. We plan to continue to invest
heavily in product development to implement open control networks. Our
development projects include the development of hardware and software products
to support ENEL's program, development of transceivers, control modules,
routers, network interface devices, network management software, development
tools, and the i.LON(TM) 1000 Internet Server. Furthermore, because our strategy
depends significantly on achieving broad adoption of our LONWORKS technology
across many industries worldwide, we plan to continue to invest heavily in
selling and marketing to promote our products. We currently believe it is
unlikely that our future rate of growth of product development, sales and
marketing expenses will fall below their historical levels. As a result, we will
need to significantly increase revenues over historical

                                       11


levels to sustain profitability in the future. Although our revenues have grown
sequentially year over year, we cannot be certain that this growth will continue
at the same rate, or that our revenues will not decline on a year over year
basis.

     Our quarterly and annual results have varied significantly, and we expect
our results to continue to vary. Many of the factors that can cause our results
to vary are outside of our control. For example, the rates at which OEMs
purchase our products and services can fluctuate. These rates are affected by
the OEMs' own business cycles. Another factor is whether we can introduce new
products in a timely manner. From time to time, we have delayed introducing new
products beyond our projected shipping date. These delays have increased costs
and postponed revenues. Because our future revenues depend on our ability to
timely introduce new product offerings, any future delays could harm our
business. Our expense levels are based substantially on the levels of future
revenues that we expect to generate. Consequently, if our revenues are less than
we expect, our expense levels could be disproportionately high as a percentage
of total revenues, and our operating results could be harmed. In the past, we
have sometimes failed to meet our expected targets for revenues. In addition,
declines in sales of our existing products over time have hurt the growth of our
revenues.

Results of Operations

     Revenues

     Total. Total revenues grew to $12.6 million in the first quarter of 2001
from $11.4 million in the first quarter of 2000. The 10.0% increase in total
revenues between the two quarters was primarily the result of an increase in
product revenues. One customer, EBV, the sole independent distributor of our
products in Europe, accounted for 30.1% of total revenues for the first quarter
of 2001 and 27.3% of total revenues for the same period in 2000.

     Product. Product revenues grew to $12.1 million in the first quarter of
2001 from $10.9 million in the first quarter of 2000. The 10.7% increase in
product revenues between the two quarters was primarily the result of an
increase in sales of control and connectivity products and development tools
products, partially offset by slight decreases in LonPoint(R) products and i.Lon
1000 Internet Servers.

     Service. Service revenues decreased to $476,000 in the first quarter of
2001 from $503,000 in the first quarter of 2000. The 5.4% decrease in service
revenues between the two quarters was primarily the result of decreased training
revenues partially offset by a slight increase in customer support revenues.

     Cost of Revenues

     Cost of product. Cost of product revenues consists of costs associated
with the purchase of components and subassemblies, as well as allocated labor,
overhead and manufacturing variance costs associated with the packaging,
preparation and shipment of products. Cost of product revenues in the first
quarter of 2001 was $4.3 million compared to $4.3 million for the same period in
2000, representing product gross margins of 64.9% for the first quarter of 2001
and 60.8% for the same period in 2000. This change in product gross margin
percentage was primarily due to fluctuations in overhead spending rates as well
as the mix of products sold during the two periods.

     Cost of service. Cost of service revenues consists of employee-related
costs as well as direct costs incurred in providing training and customer
support services. Cost of service revenues increased to $537,000 for the first
quarter of 2001 from $482,000 for the comparative period in 2000, an increase of
11.4%, representing service gross margins of (12.8%) for the first quarter of
2001 and 4.2% for the same period in 2000. The decline in service gross margins
for the quarter was primarily due to increased personnel costs and a decrease in
training revenues.

     Operating Expenses

     Product development. Product development expenses consist primarily of
payroll and related expenses, expensed material and facility costs associated
with the development of new technologies and products. Product development
expenses for the first quarter of 2001 grew to $3.8 million from $2.4 million in
the first quarter of 2000, representing 30.4% of total revenues for the first
quarter of 2001 and 20.7% of total revenues for the same period in 2000. This
increase in product develepment expenses is primarily the result of increased
personnel costs, increased expensed material and depreciation costs, and
expenses related to the operation of Arigo Software GmbH which we acquired in
February 2001.

                                       12


     Sales and marketing. Sales and marketing expenses consist primarily of
payroll and related expenses, including commissions to sales personnel, travel
and entertainment, advertising and product promotion and facilities costs
associated with our sales and support offices. Sales and marketing expenses for
the first quarter of 2001 decreased to $3.9 million from $4.1 million in the
first quarter of 2000, representing 30.9% of total revenues for the first
quarter of 2001 and 35.6% of total revenues for the same period in 2000. This
decrease in sales and marketing expenses was the result of decreased worldwide
personnel and advertising costs partially offset by increased travel expenses.

     General and administrative. General and administrative expenses consist
primarily of payroll and related expenses for executive, accounting and
administrative personnel, insurance, professional fees and other general
corporate expenses. General and administrative expenses in the first quarter of
2001 increased to $2.3 million from $1.2 million in the first quarter of 2000,
representing 18.4% of total revenues for the first quarter of 2001 and 10.2% of
total revenues for the same period in 2000. This increase in general and
administrative expenses was primarily the result of legal fees and the $475,000
settlement charge related to the Calabrese patent infringement lawsuit, and to a
lesser extent, an increase in our provision for bad debts.

     Interest and other income, net

     Interest and other income, net primarily reflects interest earned by our
company on cash and short-term investment balances. Interest and other income,
net for the first quarter of 2001 increased to $2.3 million from $322,000 for
the comparable period in 2000. This increase was primarily due to the higher
average balance of invested cash during the first quarter of 2001.

     Provision for income taxes

     The provision for income taxes for the quarter ended March 31, 2001
includes a provision for Federal, state and foreign taxes based on our annual
estimated effective tax for the year. The difference between the statutory rate
and our effective tax rate is primarily due to the impact of foreign taxes and
the beneficial impact of deferred taxes resulting from the utilization of net
operating losses. Income taxes for the quarter ended March 31, 2000 primarily
consist of taxes related to profitable foreign subsidiaries and various state
minimum taxes. Income taxes were $1,000 for the first quarter of 2001 and
$40,000 for the same period in 2000.

Liquidity and Capital Resources

     Since our inception, we have financed our operations and met our capital
expenditure requirements primarily from the sale of preferred stock and common
stock. From inception through March 31, 2001, we had raised $264.4 million from
the sale of preferred stock and common stock.

     As of March 31, 2001, we had cash, cash equivalents and short-term
investments of $147.0 million. Net cash used in operating activities was
$571,000 for the three months ended March 31, 2001 compared to $1.5 million
during the same period of 2000. Cash used in 2001 was principally the result of
a planned increase in inventories and a decrease in our deferred revenues,
partially offset by increases in accounts payable and accrued liabilities and a
decrease in accounts receivable. Cash used in 2000 was principally the result of
a planned increase in inventories and the net loss.

     Net cash used for investing activities for the three months ended March
31, 2001 of $11.5 million was principally due to the purchase of available-for-
sale short-term investments, a $3.4 million increase in other long-term assets,
and to a lesser extent, by capital expenditures of $528,000. For the three
months ended March 31, 2000, net cash provided by investing activities of $8.0
million was principally due to the net proceeds from maturities and sales of
available-for-sale investments, slightly offset by capital expenditures of
$307,000.

     Net cash provided by financing activities of $790,000 and $1.6 million
for the first quarters of 2001 and 2000 was principally due to the proceeds from
the exercise of stock options by employees.

     We believe that our existing available cash, cash equivalents and short-
term investments will satisfy our projected working capital and other cash
requirements for at least the next twelve months. However, in the unlikely event
that we would require additional financing within this period, such financing
may not be available to us in the amounts or at the times that we require, or on
acceptable terms. If we fail to obtain additional financing, when and if
necessary, our business would be harmed.

                                       13


New Accounting Standards

     In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133," which amends SFAS No. 133 to be
effective for all fiscal years beginning after June 15, 2000. SFAS No. 133
establishes accounting and reporting standards requiring that every derivative
instrument be recorded in the balance sheet as either an asset or liability
measured at its fair value. The statement also requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. We do not currently engage in any hedging
activities and do not hold any derivative instruments. Accordingly, there was no
impact on our financial position, results of operations or cash flows on the
adoption of SFAS 133 in the quarter ended March 31, 2001.

     In the fourth quarter of 2000, we adopted Staff Accounting Bulletin No.
101, "Revenue Recognition in Financial Statements," as amended ("SAB 101"),
issued by the Securities and Exchange Commission in December 1999. SAB 101
provides guidance on applying generally accepted accounting principles to
revenue recognition issues in financial statements. The adoption of SAB 101 did
not result in a change to the method of accounting for revenue nor did it have a
material effect on our financial position or results of operations or the
quarterly results during 2000.

Item 3.   Quantitative and Qualitative Disclosures about Market Risks

     There has not been any material change in our exposure to interest rate and
foreign currency risks since the date of our Form 10-K for the year ended
December 31, 2000.

     Interest Rate Risk. Our exposure to market risk for changes in interest
rates relates primarily to our investment portfolio. All our investments are in
high-credit quality issuances, and, by our company policy, are limited in the
amount of credit exposure to any one issuer. We ensure the safety and
preservation of the invested principal funds by investing only in marketable
securities with active secondary or resale markets to maintain portfolio
liquidity. The table below presents principal amounts and related weighted
average interest rates for our investment portfolio at March 31, 2001. According
to our policy, all investments mature in two years or less.

     Foreign Currency Exchange Risk. We transact business in various foreign
countries. Our primary foreign currency cash flows are in Japan. Currently, we
do not employ a foreign currency hedge program utilizing foreign currency
exchange contracts as the foreign currency transactions and risks to date have
not been significant.

Factors That May Affect Future Results of Operations

     Interested persons should carefully consider the risks described below in
evaluating Echelon. Additional risks and uncertainties not presently known to us
or that we currently consider immaterial may also impair our business
operations. If any of the following risks actually occur, our business,
financial condition or results of operations could be materially adversely
affected. In that case, the trading price of our common stock could decline.

We have a history of losses, and we may incur losses in the future.

     Although we generated a profit, in the amount of $22,000, for the third
consecutive quarter during the first quarter of 2001, we have incurred net
losses in all other periods since our inception. As of March 31, 2001, we had

                                       14


an accumulated deficit of $94.3 million. We have invested and continue to invest
significant financial resources in product development, marketing and sales. If
our revenues do not increase significantly as a result of these expenditures, we
may not be able to sustain profitability. There is also no guarantee that, since
profitability has now been achieved, it will continue or increase on a quarterly
or annual basis. Our future operating results will depend on many factors,
including:

     .  the growth of the markets for our products, especially utility/home
        automation products;
     .  the acceptance of our products;
     .  the level of competition that we face;
     .  our ability to develop and market new products; and
     .  general economic conditions.

     As of December 31, 2000, we had net operating loss carryforwards for
Federal income tax reporting purposes of about $101.1 million and for state
income tax reporting purposes of about $11.1 million, which expire at various
dates through 2020. In addition, as of December 31, 2000, we had tax credit
carryforwards of about $5.6 million, which expire at various dates through 2020.
The Internal Revenue Code of 1986, as amended, contains provisions that may
limit the use in any future period of net operating loss and credit
carryforwards upon the occurrence of certain events, including a significant
change in ownership interests. We have performed an analysis of our ownership
changes and have reported the net operating loss and credit carryforwards
considering such limitations. We had deferred tax assets, including our net
operating loss carryforwards and tax credits, totaling about $44.2 million as of
December 31, 2000. A valuation allowance has been recorded for the entire
deferred tax asset as a result of uncertainties regarding the realization of the
asset balance, our history of losses and the variability of our operating
results.

Our limited history and the undetermined market acceptance of our products make
it difficult to evaluate our future prospects.

     We have only a limited operating history on which you can base your
evaluation of our business. We face a number of risks as an emerging company in
a new market, and you must consider our prospects in light of these risks. Our
future operating results are difficult to predict due to many factors, including
the following:

     .  our targeted markets have not yet accepted many of our products and
        technologies;
     .  the nature of our business and markets require rapid progress;
     .  potential changes in voluntary product standards can significantly
        influence many of the markets for our products; and
     .  our industry is very competitive.

Our future results could be significantly harmed if our project with ENEL is not
successful.

     We have entered into a research and development agreement with an affiliate
of ENEL S.p.A., an Italian utility company, under which we will cooperate with
ENEL to integrate our LONWORKS system into ENEL's remote metering management
project in Italy. This project is called "Contratore Elettronico." We face a
number of risks as we undertake this project, including:

     .  our research and development activities under this project might be
        unsuccessful, or might not be commercially exploitable;
     .  the Contratore Elettronico project might not meet target dates;
     .  the products we develop for the Contratore Elettronico project might not
        yield economic returns; or
     .  the research and development agreement might be terminated if, among
        other things, either party materially breaches its obligations under the
        agreement; or
     .  third parties may contest part or all of the agreement.

     If our efforts under this research and development agreement or the related
Contratore Elettronico project are not successful, our revenues and income could
suffer.

                                       15


Fluctuations in our operating results may cause our stock price to decline.

     Our quarterly and annual results have varied significantly, and we have
failed to meet securities analysts' expectations in the past. Our future results
may fluctuate and may not meet those expectations in some future period. As a
result, the price of our common stock could fluctuate or decline. The factors
that could cause this variability, many of which are outside of our control,
include the following:

     .  fluctuations in the rates at which OEMs purchase our products and
        services;
     .  OEMs' own business cycles;
     .  our ability to introduce new products on a timely basis;
     .  any downturns in any customer's or potential customer's business, or
        declines in general economic conditions that cause significant
        reductions in their capital spending;
     .  increased competition;
     .  market acceptance of our products;
     .  product life cycles;
     .  order delays or cancellations;
     .  changes in the mix of products and services that we sell;
     .  shipment and payment schedules;
     .  changes in our pricing policies or those of our competitors;
     .  changes in product distribution; and
     .  product ratings by industry analysts and endorsement of competing
        products by industry groups.

     In addition, our expense levels are based, in significant part, on the
future revenues that we expect. Consequently, if our revenues are less than we
expect, our expense levels could be disproportionately high as a percentage of
total revenues.

If our OEMs do not employ our products and technologies, or if we do not
maintain and expand our distribution channels, our revenues could decrease
significantly.

     To date, substantially all of our product sales have been to OEMs. The
product and marketing decisions made by OEMs significantly affect the rate at
which our products are used in control networks. We believe that since OEMs in
certain industries receive a large portion of their revenues from sales of
products and services to their installed base, these OEMs have tended to
moderate the rate at which they incorporate LonWorks technology into their
products. We have attempted to motivate OEMs, as well as systems integrators and
owners of control systems, to transition more rapidly to LonWorks technology.
Furthermore, OEMs that manufacture and promote products and technologies that
compete or may compete with us may be particularly reluctant to employ our
products and technologies to any significant extent, if at all. We may not be
able to maintain or improve the current rate at which our products are accepted
by OEMs and others, which could decrease our revenues.

     Currently, significant portions of our revenues are derived from sales by
EBV, the sole independent distributor of our products to OEMs in Europe. EBV
accounted for 30.1% of total revenues for the quarter ended March 31, 2001 and
27.3% of total revenues for the same period in 2000. Our current agreement with
EBV expires in December 2001. In addition, as part of our distribution strategy,
we intend to develop distribution arrangements with systems integrators. In
particular, we expect that a significant portion of our future revenues will be
derived from sales by such systems integrators. If EBV, or any other existing or
future distributor, fails to dedicate sufficient resources and efforts to
marketing and selling our products, our revenues could decrease. If EBV
significantly reduces the stocking levels for our products, both revenues and
customer service levels would be decreased. In that case, we might be required
to add our own pan-European distribution capability to meet the needs of our
customers. Our business will be harmed if we fail to do any of the following:

     .  develop new distribution channels;
     .  maintain the EBV arrangement or any other distribution channels; or
     .  renew the EBV arrangement on a timely basis.

                                       16


If OEMs fail to develop interoperable products or if our interoperable products
are not accepted by our targeted markets, we may be unable to generate sales of
our products.

     Our future operating success will depend, in significant part, on the
successful development of interoperable products by us and OEMs, and the
acceptance of interoperable products by systems integrators and end-users. We
have expended considerable resources to develop, market and sell interoperable
products, and have made such products a cornerstone of our sales and marketing
strategy. We have widely promoted interoperable products as offering benefits
such as lower life-cycle costs and improved flexibility to owners and users of
control networks. However, OEMs that manufacture and market closed systems may
not accept, promote or employ interoperable products, since doing so may expose
their businesses to increased competition. In addition, OEMs might not, in fact,
successfully develop interoperable products, or their interoperable products
might not be accepted by their customers. If OEMs fail to develop interoperable
products, or interoperable products are not accepted by our markets, our
revenues will suffer.

We depend on a limited number of key manufacturers for Neuron Chips and use
contract electronic manufacturers for most of our products requiring assembly.
If any of these manufacturers terminates or decreases its relationships with us,
we may not be able to supply our products and our revenues would suffer.

     The Neuron Chip is an important component that our customers use in control
network nodes. In addition, the Neuron Chip is an important device that we use
in many of our products. Neuron Chips are currently manufactured and distributed
by Toshiba, and will be in the future by Cypress Semiconductor. Motorola also
manufactured and distributed Neuron Chips until January 31, 2001. We have
entered into licensing agreements with each of Toshiba and Cypress. The
agreements, among other things, grant Toshiba and Cypress the worldwide right to
manufacture and distribute Neuron Chips using technology licensed from us and
require us to provide support and unspecified updates to the licensed technology
over the terms of the agreements. We had a similar agreement with Motorola,
which expired in January 2001. The Cypress agreement expires in April 2009, and
the Toshiba agreement expires in January 2010. Motorola discontinued
manufacturing and distribution of Neuron Chips after January 31, 2001. While we
developed the first version of the Neuron Chip, Motorola and Toshiba
subsequently developed improved, lower-cost versions of the Neuron Chip that are
presently used in products that our customers and we develop and sell. We
currently have no other source of supply for Neuron Chips and have neither the
resources nor the skills to replace Toshiba or Cypress as a manufacturer of
Neuron Chips. Both Motorola and Toshiba have played, and Toshiba and Cypress are
expected to play, a key role in the development and marketing of LONWORKS
technology. If we lose Toshiba or Cypress as a supplier, we may not be able to
locate an alternate source for the design, manufacture or distribution of Neuron
Chips.

     Our future success will also depend significantly on our ability to
successfully manufacture our products cost-effectively and in sufficient
volumes. For most of our products requiring assembly, we use contract electronic
manufacturers, including Able Electronics, Transpower Technologies, Escatec
Electronics and muRata Electronics. These contract electronic manufacturers
procure material and assemble, test and inspect the final products to our
specifications. This strategy involves certain risks. By using third parties to
manufacture our products, we have reduced control over delivery schedules,
product availability, manufacturing yields, quality and costs. In addition,
contract electronic manufacturers can themselves experience turnover and
instability exposing us to additional risks as well as missed commitments to our
customers. We will also face risks if and when we transition between contract
electronic manufacturers. For example, we may have to move raw material and in
process inventory between locations in different parts of the world. Also, we
would be required to reestablish acceptable manufacturing processes with a new
work force.

Because we depend on sole or a limited number of suppliers, any shortage or
interruptions of supply would adversely affect our revenues and/or gross
profits.

     We currently purchase several key components only from sole or limited
sources. If we experience any shortage of products or components of acceptable
quality, or any interruption in the supply of these products or components, or
if we are not able to procure these products or components from alternate
sources at acceptable prices and within a reasonable period of time, our
revenues and/or gross profits could decrease. In the past, we have sometimes
experienced shortages or supply interruptions of products or components, which
caused us to delay shipments beyond targeted or announced dates.

Our markets are highly competitive. Many of our competitors have longer
operating histories and greater resources than we do. If we are unable to
effectively compete in the industry, our operating results could be harmed.

     Competition in our markets is intense and involves rapidly changing
technologies, evolving industry standards, frequent new product introductions
and rapid changes in customer requirements. To maintain and improve our
competitive position, we must continue to develop and introduce, on a timely and
cost-effective basis, new products, features and services that keep pace with
the evolving needs of our customers. The principal competitive factors that
affect the markets for our control network products are the following:

     .  our customer service and support;
     .  our product reputation, quality, performance; and
     .  the price and features of our products such as adaptability,
        scalability, the ability to integrate with other products,
        functionality, and ease of use.

     In each of our markets, we compete with a wide array of manufacturers,
vendors, strategic alliances, systems developers and other businesses. Our
competitors include some of the largest companies in the electronics industry,
such as Siemens in the building and industrial automation industries,
Allen-Bradley (a subsidiary of Rockwell) and Group Schneider in the industrial
automation industry, and Microsoft. Many of our competitors, alone or together
with their trade associations and partners, have significantly greater
financial, technical, marketing, service and other resources, significantly
greater name recognition and broader product offerings. As a result, these
competitors may be able to devote greater resources to the development,
marketing and sale of their products, and may be able to respond more quickly to
changes in customer requirements or product technology. In addition, those
competitors that manufacture and promote closed, proprietary control systems may
enjoy a captive customer base dependent on such competitors for service,
maintenance, upgrades and enhancements. Most recently, Microsoft has announced a
specification that it refers to as SCP (Simple Control Protocol) which is
targeted at the networking of everyday devices. Microsoft has announced its
intention to focus this capability on home networking applications. Products
from emerging companies such as emWare could also compete with our products,
especially in the utility/home market. Even if we believe that the products
offered by some of these companies do not provide the robust and open networking
solutions offered by LonWorks networks, we would be required to educate our
customers about what we believe are the potential long-term cost and
functionality problems inherent in such alternative solutions. However, our
customers may believe that these alternative products are satisfactory for their
needs.

Many of our competitors support and promote closed or proprietary control
systems, and if we cannot promote and expand acceptance of open, interoperable
control systems, our revenues and operating results may be harmed.

     Many of our current and prospective competitors are dedicated to promoting
closed or proprietary systems, technologies, software and network protocols or
product standards that differ from, or are incompatible with ours. In some
cases, companies have established associations or cooperative relationships to
enhance the competitiveness and popularity of their products, or to promote
these different or incompatible technologies, protocols and standards. For
example, in the building automation market, we face widespread reluctance by
vendors of traditional closed or proprietary control systems, who enjoy a
captive market for servicing and replacing equipment, to use our interoperable
technologies. We also face strong competition by large trade associations that
promote alternative technologies and standards in their native countries, such
as the BatiBus Club International in France and the European Installation Bus
Association in Germany, each of which has over 100 members and licensees. Other
examples include the CEBus Industry Council, which is the proponent of an
alternative protocol to our LonWorks protocol for use in the utility/home
automation industry, and a group comprised of Asea Brown Boveri, ADtranz AB,
Siemens, GEC Alstrom and other manufacturers that support an alternative rail
transportation protocol to our LonWorks protocol. Our technologies, protocols or
standards may not be successful in any of our markets, and we may not be able to
compete with new or enhanced products or standards introduced by existing or
future competitors.

     LonWorks technology is open, meaning that many of our technology patents
are broadly licensed without royalties or license fees. As a result, our
customers are capable of developing products that compete with some of our
products. Because some of our customers are OEMs that develop and market their
own control systems, these

                                       18


customers in particular could develop competing products based on our open
technology. This could decrease the market for our products and increase the
competition that we face.

The trading price of our stock has been volatile, and may fluctuate due to
factors beyond our control.

     The trading price of our common stock is subject to significant
fluctuations in response to numerous factors, including:

 .  our quarterly operating results may vary widely;
 .  our customers or we may announce technological innovations or new products;
 .  securities analysts may change their estimates of our financial results; and
 .  significant stockholders may sell some or all of their holdings of our stock.

     In addition, the market price of securities of technology companies,
especially those in new or emerging industries such as ours, has been very
volatile in the past. This volatility has often been unrelated or
disproportionate to the operating performance of particular companies. In the
future, our operating results may fall below analysts' expectations, which could
adversely affect the market price of our stock.

In the future, we may be the target of securities class action lawsuits or other
litigation, which could be costly and time consuming to defend.

     In the past, following a period of volatility in the market price of a
company's securities, securities class action lawsuits have often been
instituted against such companies. We may in the future be the target of similar
litigation. If such a lawsuit were brought against us, regardless of its
outcome, we would incur substantial costs and our management resources would be
diverted in defending such litigation.

Our executive officers and technical personnel are critical to our business, and
if we lose or fail to attract our key personnel, we may not be able to
successfully operate our business.

     Our performance depends substantially on the performance of our executive
officers and key employees. We are dependent in particular on our Chief
Executive Officer, as well as our technical personnel, due to the specialized
technical nature of our business. Our future success will depend on our ability
to attract, integrate, motivate and retain qualified technical, sales,
operations and managerial personnel. Competition for qualified personnel in our
business areas is intense, and we may not be able to continue to attract and
retain qualified executive officers and key personnel necessary to enable our
business to succeed. Our product development and marketing functions are largely
based in Silicon Valley, a highly competitive marketplace. It is particularly
difficult to recruit, relocate and retain qualified personnel in this geographic
area. In addition, if we lose the services of any of our key personnel and are
not able to find replacements in a timely manner, our business could be
disrupted, other key personnel may decide to leave, and we may incur increased
operating expenses in finding and compensating a replacement.

The market for our products is new and rapidly evolving. If we are not able to
develop or enhance products to respond to changing market conditions, our
revenues will suffer.

     Customer requirements for control network products can change as a result
of innovations or changes within the building, industrial, transportation,
utility/home and other industries. For example, new or different standards
within industry segments may be adopted, giving rise to new customer
requirements. These customer requirements may or may not be compatible with our
current or future product offerings. Our future success depends in large part on
our ability to continue to enhance existing products, lower product cost and
develop new products that maintain technological competitiveness. We may not be
successful in modifying our products and services to address these requirements
and standards. For example, certain of our competitors may develop competing
technologies based on Internet Protocols (IP) that may have advantages over our
products in remote connection. In addition, from time to time, we have delayed
introducing new products beyond our projected shipping date for such products.
In each instance, these delays increased our costs and delayed our revenues.

                                       19


Voluntary standards that are established in our markets could limit our ability
to sell our products and reduce our revenues.

    Standards bodies, which are formal and informal associations that attempt to
set voluntary, non-governmental product standards, are influential in many of
our target markets. Some of our competitors have attempted to use voluntary
standards to reduce the market opportunity for our products, or to increase the
market opportunity for the competitors' products, by lobbying for the adoption
of voluntary standards that would exclude or limit the use of our products. We
participate in many voluntary standards processes both to avoid adoption of
exclusionary standards and to promote voluntary standards for our products.
However, we do not have the resources to participate in all voluntary standards
processes that may affect our markets. The adoption of voluntary standards that
are incompatible with our products or technology could limit the market
opportunity for our products.

As a result of our lengthy sales cycle, we have limited ability to forecast the
amount and timing of specific sales. If we fail to complete or are delayed in
completing transactions, our revenues could vary significantly from period to
period.

    The sales cycle between initial customer contact and execution of a contract
or license agreement with a customer can vary widely. OEMs typically conduct
extensive and lengthy product evaluations before making initial purchases of our
products. Subsequent purchases of our products may be delayed by prolonged
product development and introduction periods for OEMs. Attendant delays in our
sales cycle can result from, among other things, changes in customers' budgets
or in the priority assigned to control network development and the need to
educate customers about the potential applications of and cost savings
associated with our products. We generally have little or no control over these
factors, which may cause a potential customer to favor a competitor's products,
or to delay or forgo purchases altogether. Also, there can be long sales cycles
between the selection of our products for use by a systems integrator, and the
purchase of such products by the systems integrator.

Defects in or misuse of our products may delay our ability to generate revenues
and may increase our liabilities and expenses.

    The products that we develop, license and sell may contain errors or
failures or may be improperly installed or implemented. Errors or failures may
be found in our products, and we may not be able to successfully correct those
errors or failures in a timely manner or at all. In addition, our products may
not be properly installed or implemented by third parties. In addition, such
errors or failures may delay our revenue recognition and divert our engineering
resources to correct such defects. We maintain errors and omissions insurance to
cover liability associated with our operations but it is possible that such
insurance may not be available or may be insufficient in amount to cover any
particular claim. During 2000, the total limit for claims under these policies
was $17.0 million. We have since then reduced the total limit for errors and
omissions claims to $2.0 million because our insurers requested premiums that we
believed were excessive. We may face increased exposure to these types of claims
as a result of the decrease in our coverage. Although our agreements with our
customers typically contain provisions intended to limit our exposure to
potential claims as well as any liabilities arising from such claims, and may in
very limited instances require that we be named as an additional insured under
the insurance policies carried by some of our customers, such contracts and
insurance may not effectively protect us against the liabilities and expenses
associated with product errors or failures. Accordingly, errors or failures in
our products or applications or improper installation or implementation of our
products by third parties could harm our operating results. In addition, because
of the low cost and interoperable nature of our products, LONWORKS technology
could be used in a manner for which it was not intended. As a result, our
reputation could be harmed and we might suffer material financial losses.

We have limited ability to protect our intellectual property rights.

    Our success depends significantly upon our intellectual property rights. We
rely on a combination of patent, copyright, trademark and trade secret laws,
non-disclosure agreements and other contractual provisions to establish,
maintain and protect our intellectual property rights, all of which afford only
limited protection. We have 78 issued U.S. patents, 14 pending U.S. patent
applications, and various foreign counterparts. It is possible that patents will
not issue from these pending applications or from any future applications or
that, if issued, any claims allowed will not be sufficiently broad to protect
our technology. If any of our patents fail to protect our technology, our
competitors may find it easier to offer equivalent or superior technology. We
have registered or applied for registration for certain trademarks, and will
continue to evaluate the registration of additional trademarks as

                                       20


appropriate. If we fail to properly register or maintain our trademarks or to
otherwise take all necessary steps to protect our trademarks, the value
associated with the trademarks may diminish. In addition, if we fail to take all
necessary steps to protect our trade secrets or other intellectual property
rights, we may not be able to compete as effectively in our markets.

     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or services or to obtain and use
information that we regard as proprietary. Any of the patents, trademarks,
copyrights or intellectual property rights that have been or may be issued or
granted to us could be challenged, invalidated or circumvented, and any of the
rights granted may not provide protection for our proprietary rights. In
addition, there can be no assurance that we have taken or will take all
necessary steps to protect our intellectual property rights. Third parties may
also independently develop similar technology without breach of our trade
secrets or other proprietary rights. We have licensed in the past and may
license in the future our key technologies to third parties. In addition, the
laws of some foreign countries, including several in which we operate or sell
our products, do not protect proprietary rights to as great an extent as do the
laws of the United States. Certain of our products are licensed under
shrink-wrap license agreements that are not signed by licensees and therefore
may not be binding under the laws of certain jurisdictions.

     From time to time, litigation may be necessary to defend and enforce our
proprietary rights. As a result of this litigation, we could incur substantial
costs and divert management resources, which could harm our business, regardless
of the final outcome. Despite our efforts to safeguard and maintain our
proprietary rights both in the United States and abroad, we may be unsuccessful
in doing so. Also, the steps that we take to safeguard and maintain our
proprietary rights may be inadequate to deter infringement, misuse,
misappropriation or independent third-party development of our technology or
intellectual property rights or to prevent an unauthorized third party from
copying or otherwise obtaining and using our products or technology.

Regulatory actions could limit our ability to market and sell our products.

     Many of our products and the industries in which they are used are subject
to U.S. and foreign regulation. Government regulatory action could greatly
reduce the market for our products. For example, the power line medium, which is
the communications medium used by some of our products, is subject to special
regulations in North America, Europe and Japan. These regulations limit the
ability of companies in general to use power lines as a communication medium. In
addition, some of our competitors have attempted to use regulatory actions to
reduce the market opportunity for some of our products or to increase the market
opportunity for the competitors' products. In the late 1990's, we experienced
efforts by CEMA, a trade association that developed a competing home automation
protocol, to persuade the FCC to mandate use of its protocol in analog
television and set-top box applications. We were a petitioner in litigation
arising from a related FCC proceeding concerning commercial availability of
these "navigation devices". An appeal under this case was recently decided in
favor of the government. We have decided not to seek Supreme Court review.
Although these specific FCC and judicial proceedings are not a significant
threat to our digital and Internet-based products, existing or future
regulations or regulatory actions could adversely affect the market for our
products or require us to expend significant management, technical or financial
resources.

We face operational and financial risks associated with international
operations.

     Our sales and marketing operations are located in nine countries. Revenues
from international sales, which include both export sales and sales by
international subsidiaries, accounted for about 67.4% of our total revenues for
the first quarter of 2001 and 62.4% of our total revenues for the same period in
2000. Our operations and the market price of our products may be directly
affected by economic and political conditions in the countries where we do
business. In addition, we may not be able to maintain or increase the
international demand for our products. Additional risks inherent in our
international business activities generally include the following:

 .  currency fluctuations;
 .  unexpected changes in regulatory requirements, tariffs and other trade
   barriers;
 .  costs of localizing products for foreign countries and lack of acceptance of
   non-local products in foreign countries;
 .  longer accounts receivable payment cycles;
 .  difficulties in managing international operations;

                                       21


 .  potentially adverse tax consequences, including restrictions on repatriation
   of earnings; and
 .  the burdens of complying with a wide variety of foreign laws.

     Differing vacation and holiday patterns in other countries, particularly in
Europe, may also affect the amount of business that we transact in other
countries in any quarter, the timing of our revenues and our ability to forecast
our projected operating results for such quarter. The portion of our revenues
that were conducted in currencies other than the U.S. dollar, principally the
Japanese yen, was about 6.9% for the first quarter of 2001 and 10.3% for the
same period in 2000. Fluctuations in the value of currencies in which we conduct
our business relative to the U.S. dollar could cause currency translation
adjustments. The introduction of the Euro as the standard currency in
participating European countries may also impact our ability to transact sales
in U.S. dollars. We have agreed with EBV, our European distributor, that upon
notice from EBV, we will sell our products to EBV in Euros rather than U.S.
dollars. We do not know when or if EBV will give such notice. If fewer of our
sales in Europe are transacted in U.S. dollars, we may experience an increase in
currency translation adjustments, particularly as a result of general economic
conditions in Europe as a whole. We do not currently engage in currency hedging
transactions or otherwise cover our foreign currency exposure.

We rely on a continuous power supply to conduct our operations, and California's
current energy crisis could disrupt our operations and increase our expenses.

     California is in the midst of an energy crisis that could disrupt our
operations and increase our expenses. In the event of an acute power shortage,
that is, when power reserves for the state of California fall below certain
critical levels, California has on some occasions implemented, and may in the
future continue to implement, rolling blackouts throughout the state. We
currently do not have backup generators or alternate sources of power in the
event of a blackout, and our current insurance does not provide coverage for any
damages we or our customers may suffer as a result of any interruption in our
power supply. If blackouts interrupt our power supply, we would be temporarily
unable to continue operations at our California facilities. Any such
interruption in our ability to continue operations at our facilities could
damage our reputation, harm our ability to retain existing customers and to
obtain new customers, and could result in lost revenue, any of which could
substantially harm our business and results of operations.

     Furthermore, the deregulation of the energy industry instituted in 1996 by
the California government has caused power prices to increase. Under
deregulation, utilities were encouraged to sell their plants, which
traditionally had produced most of California's power, to independent energy
companies that were expected to compete aggressively on price. Instead, due in
part to a shortage of supply, wholesale prices have skyrocketed over the past
year. If wholesale prices continue to increase, the operating expenses
associated with our facilities located in California will likely increase which
would harm our results of operations.

Our existing stockholders control a significant percentage of our stock, which
will limit other stockholders' ability to influence corporate matters.

     As of April 30, 2001, our directors and executive officers, together with
certain entities affiliated with them, beneficially owned 37.4% of our
outstanding stock.

     Under the stock purchase agreement with ENEL, which transaction was
completed September 11, 2000, ENEL purchased 3 million newly issued shares of
our common stock and was granted the right to nominate a director to our Board
of Directors. As a condition to the closing of the stock purchase agreement, our
directors and our chief financial officer agreed to enter into a voting
agreement with ENEL in which each of them agreed to vote the shares of our
company's common stock that they beneficially owned or controlled in favor of
ENEL's nominee to our Board of Directors. In addition, under the terms of the
stock purchase agreement, ENEL has agreed to (i) vote (and cause any of its
affiliates that own shares of our common stock to vote) all of its shares in
favor of the slate of director nominees recommended by the Board of Directors,
and (ii) vote (and endeavor to cause any of its affiliates that own shares of
our common stock to vote) a number of shares equal to at least that percentage
of shares voted by all other stockholders for or against any specified matter,
as recommended by the Board of Directors. The specified matters are the election
of accountants, the approval of company options plans, and any proposal by any
of our stockholders (unless the proposal could be prejudicial to ENEL or the
required voting would interfere with ENEL's fiduciary duties to its own
shareholders).

                                       22


     Under the terms of another stock purchase agreement, one other stockholder
that owns less than 0.5% of our outstanding common stock has agreed to vote (i)
all of its shares in favor of the slate of director nominees recommended by the
Board of Directors, and (ii) a number of shares equal to at least that
percentage of shares voted by all other stockholders for or against any given
matter, as recommended by the Board of Directors (except certain matters
relating to certain changes to our charter, liquidations, a sale of our company
or a merger of our company into another entity), as recommended by a majority of
our Board of Directors.

     As a result, our directors and executive officers, together with certain
entities affiliated with them, may be able to control substantially all matters
requiring approval by our stockholders, including the election of all directors
and approval of certain other corporate matters.


                          PART II. OTHER INFORMATION

Item 1.   Legal Proceedings

     On July 19, 2000, an individual, Kathleen Calabrese, brought suit against
our company by adding our company to one of five defendants in her amended
complaint filed in the Federal District Court for the Northern District of
Illinois. Calabrese sued for alleged direct and indirect infringement of a
recently expired patent claiming a data relay system. We believe that we did not
infringe the patent. On March 26, 2001, we reached a settlement agreement
related to the Calabrese lawsuit, pursuant to which we would pay Calabrese
$475,000 in full settlement of all her claims against our company. As part of
the settlement, Calabrese released and discharged us, our customers, our
distributors and users of our products, and any third party manufacturers,
distributors, system integrators and users of products incorporated in LONWORKS
networks, of any claims related to the patent in question. We also released and
discharged any claims against Calabrese related to the patent in question.
