FORWARD-LOOKING
INFORMATION

This report contains forward-looking statements within the meaning of the U.S. federal securities laws
that involve risks and uncertainties. Certain statements contained in this report are not purely historical including, without limitation, statements regarding our expectations, beliefs, intentions, anticipations, commitments or strategies regarding
the future that are forward-looking. These statements include those discussed in Item 2, Managements Discussion and Analysis of Financial Condition and Results of Operations, including Critical Accounting Estimates,
Results of Operations, Off-Balance-Sheet Arrangements and Other Critical Contractual Obligations, Liquidity and Capital Resources, and Recently Issued Accounting Standards, and elsewhere in this
report.

In this report, the words may, could, would, might,
will, should, plan,  forecast, anticipate, believe, expect, intend, estimate, predict, potential,
continue, future, moving toward or the negative of these terms or other similar expressions also identify forward-looking statements. Our actual results could differ materially from those forward-looking
statements contained in this report as a result of a number of risk factors including, but not limited to, those set forth in the section entitled Factors That May Affect Future Results of Operations and elsewhere in this report. You
should carefully consider these risks, in addition to the other information in this report and in our other filings with the SEC. All forward-looking statements and reasons why results may differ included in this report are made as of the date of
this report, and we assume no obligation to update any such forward-looking statement or reason why such results might differ.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Summary of Significant Accounting Policies:

Basis of Presentation

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

While the financial information furnished is unaudited, the condensed consolidated financial statements 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 Companys consolidated financial statements
for the year ended December 31, 2009 included in its Annual Report on Form 10-K.

With the exception of the adoption of
accounting pronouncements related to revenue recognition discussed in the section titled Revenue Recognition below, there have been no material changes to the Companys significant accounting policies, as compared to the
significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.

Risks and Uncertainties

The Companys operations and performance depend significantly on worldwide economic conditions and their impact on purchases of the Companys products, as well as the ability of suppliers to
provide the Company with products and services in a timely manner. The impact of any of the matters described below could have an adverse affect on the Companys business, results of operations and financial condition.



| |  |  | The Companys sales are currently concentrated with a relatively small group of customers, as approximately 47% of net revenues for the three
months ended September 30, 2010, and 48% of net revenues for the nine months ended September 30, 2010, were derived from three customers. These or any customers in any of the Companys target market sectors may experience unexpected
reductions in demand for their products and reduce their purchase orders from us, resulting in either the loss of a significant customer or a notable decrease in the level of sales to a significant customer. In addition, if any of these customers is
unable to obtain the necessary capital to operate its business, it may be unable to satisfy its payment obligations to the Company.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Company utilizes third-party contract electronic manufacturers to manufacture, assemble, and test its products. As a result of current credit
market conditions, if any of these third-parties were unable to obtain the necessary capital to operate their business, they may be unable to provide the Company with timely services or to make timely deliveries of
products.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Due to the continuing worldwide economic situation, coupled with the fact that the Companys NES customers generally procure products that have
been customized to meet their requirements, the Company has limited visibility into ultimate product demand, which makes sales forecasting more difficult. As a result, anticipated demand may not materialize, which could subject the Company to
increased levels of excess and obsolete inventories.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Company has historically experienced shortages or interruptions in supply for certain products or components used in the manufacture of the
Companys products that have been or will be discontinued. In order to ensure an adequate supply of these items, the Company has occasionally purchased quantities of these items that are in excess of the Companys then current estimate of
short-term requirements. If the long-term requirements do not materialize as originally expected, and the Company is not otherwise able to dispose of these excess products or components, it could subject the Company to increased levels of excess and
obsolete inventories. For example, to ensure supply, the Company procured a substantial quantity of a certain component used in one of its NES products. If the long-term requirements do not materialize as originally expected, or if the Company
develops alternative solutions that no longer employ these items and the Company is not able to dispose of these excess products or components, it could subject the Company to increased levels of excess and obsolete inventories.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Use of
Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles
generally accepted in the United States of America requires management to make judgments, assumptions, and estimates that affect amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Significant estimates and
judgments are used for revenue recognition, stock-based compensation, allowance for doubtful accounts, inventory valuation, allowance for warranty costs, income taxes, and other loss contingencies. In order to determine the carrying values of assets
and liabilities that are not readily apparent from other sources, the Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes to be reasonable under the circumstances. Actual
results experienced by the Company may differ materially from managements estimates.

Recently Issued Accounting
Standards

There have been no new recent accounting pronouncements or changes in accounting pronouncements during the
nine months ended September 30, 2010, with the exception of those discussed in the section Revenue Recognition below, as compared to the recently issued accounting pronouncements described in the Companys Annual Report
on Form 10-K for the fiscal year ended December 31, 2009, that are of significance, or potential significance, to the Company.

Revenue Recognition

In October 2009, the Financial Accounting
Standards Board (FASB) amended the accounting standards for revenue recognition to remove tangible products containing software components and non-software components that function together to deliver the products essential
functionality from the scope of industry specific software revenue recognition guidance. In October 2009, the FASB also amended the accounting standards for multiple deliverable revenue arrangements to:



| |  |  | provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration
should be allocated;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | require an entity to allocate revenue in an arrangement using its best estimated selling price (BESP) of deliverables if a vendor does not
have vendor-specific objective evidence (VSOE) of selling price or third-party evidence (TPE) of selling price; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------

The Company elected to early adopt this accounting guidance at the beginning of its first quarter of fiscal
year 2010 on a prospective basis for applicable transactions originating or materially modified after December 31, 2009.

Multiple Element Arrangements

The Companys multiple deliverable revenue arrangements are primarily related to sales of its NES System products, which may include, within a single arrangement, electricity meters and data
concentrators (collectively, the Hardware); NES System software; Element Manager software; post-contract customer support (PCS) for the NES System and Element Manager software; extended warranties for the Hardware; and,
occasionally, specified enhancements or upgrades to software used in the NES System. For arrangements originating or materially modified after December 31, 2009, with the exception of the NES System software, each of these deliverables is
considered a separate unit of accounting. The NES System software functions together with an electricity meter to deliver its essential functionality and any related software license fee is charged for on a per meter basis. Therefore, the NES System
software and an electricity meter are combined and considered a single unit of accounting. The Element Manager software is not considered to be part of an electricity meters essential functionality and, therefore, Element Manager software and
any related PCS continues to be accounted for under industry specific software revenue recognition guidance. However, all other NES system deliverables are no longer within the scope of industry specific software revenue recognition guidance.

The Company
allocates revenue to each element in a multiple-element arrangement based upon their relative selling price. The Company determines the selling price for each deliverable using VSOE of selling price or TPE of selling price, if it exists. If neither
VSOE nor TPE of selling price exists for a deliverable, the Company uses its BESP for that deliverable. Since the use of the residual method is eliminated under the new accounting standards, any discounts offered by the Company are allocated to each
of the deliverables. Revenue allocated to each element is then recognized when the basic revenue recognition criteria is met for the respective element.

Consistent with its methodology under previous accounting guidance, if available, the Company determines VSOE of fair value for each element based on historical stand-alone sales to third parties or from
the stated renewal rate for the elements contained in the initial contractual arrangement. The Company currently estimates selling prices for its PCS and extended warranties based on VSOE of fair value.

In many instances, the Company is not currently able to obtain VSOE of fair value for all deliverables in an arrangement with multiple
elements. This may be due to the Company infrequently selling each element separately or not pricing products within a narrow range. When VSOE cannot be established, the Company attempts to estimate the selling price of each element based on TPE.
TPE would consist of competitor prices for similar deliverables when sold separately. Generally, the Companys offerings contain significant differentiation such that the comparable pricing of products with similar functionality cannot be
obtained. Furthermore, the Company is unable to reliably determine the stand-alone selling prices for similar products of its competitors. Therefore, the Company is typically not able to obtain TPE of selling price.

When the Company is unable to establish a selling price using VSOE or TPE, which is generally the case for the Hardware and certain
specified enhancements or upgrades to the Companys NES software, the Company uses its BESP in determining the allocation of arrangement consideration. The objective of BESP is to determine the price at which the Company would transact a sale
if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.

The Company establishes pricing for its products and services by considering multiple factors including, but not limited to, geographies,
market conditions, competitive landscape, internal costs, gross margin objectives, and industry pricing practices. The determination of pricing also includes consultation with and formal approval by the Companys management, taking into
consideration the Companys go-to-market strategy. These pricing practices apply to both the Companys Hardware and software products.

For the Companys Hardware products, the Company has performed an analysis of contractual pricing stated in historical multiple-element transactions and, to a lesser extent, historical standalone
transactions. Based on this analysis, the Company has concluded that it typically prices its Hardware within a narrow range of discounts when compared to the price listed on the Companys standard pricing grid for similar deliverables (i.e.,
similar configuration, volume, geography, etc.). Therefore, the Company has determined that, for its current Hardware for which VSOE or TPE is not available, the Companys BESP is generally comprised of prices based on a narrow range of
discounts from pricing stated in its pricing grid.

When establishing BESP for the Companys specified software
enhancements or upgrades, the Company considers multiple factors including, but not limited to, the relative value of the features and functionality being delivered by the enhancement or upgrade as compared to the value of the software product to
which the enhancement or upgrade relates, as well as the Companys pricing practices for NES System software PCS packages, which may include rights to the specified enhancements or upgrades.

The Company regularly reviews VSOE and has established a review process for TPE and BESP. The Company maintains internal controls over
the establishment and updates of these estimates. There were no material impacts during the three and nine months ended September 30, 2010 resulting from changes in VSOE, TPE, or BESP, nor does the Company expect a material impact from such
changes in the near term.

Total net revenues
as reported and unaudited pro forma total net revenues that would have been reported during the three and nine months ended September 30, 2010, if the transactions entered into or materially modified after December 31, 2009 were subject to
previous accounting guidance, are shown in the following table (in thousands):



|                                                                 |  |            |        |  |                                                                   |   |        |

|Total net revenues for the three months ended September 30, 2010 |  | $          | 27,124 |  |                                                                   | $ | 26,352 | 
|Total net revenues for the nine months ended September 30, 2010  |  | $          | 72,227 |  |                                                                   | $ | 70,542 | 

The impact to total
net revenues during the three and nine months ended September 30, 2010 resulting from the adoption of the new accounting guidance was to net product revenues, and related solely to sales of the Companys NES products and services. For both
the three and nine months ended September 30, 2010, the impact was related primarily to the fact that, under the new accounting guidance, the Company recorded revenue on certain transactions for which the previous accounting guidance would have
required deferral. These transactions involved multiple element arrangements where certain software upgrades had not yet been delivered as of September 30, 2010. Under the new accounting guidance, the Company determined the BESP for the
software upgrades and deferred the relative selling price of these undelivered items accordingly. Under the previous accounting guidance, all revenue related to these transactions would have been deferred as the Company did not have VSOE of fair
value for the undelivered items.

As it relates to the timing and pattern of revenue recognition for NES product sales in the
future, the new accounting guidance has had a significant effect on total net revenues for transactions entered into or materially modified after December 31, 2009, and the Company expects this trend to continue. This expectation is primarily
due to the fact that the Company does not currently have VSOE of fair value for most of its NES product offerings, which often resulted in deferral of revenue as discussed below. In the future, for NES arrangements subject to the new revenue
recognition guidance, revenue allocated to meters and data concentrators will be recognized as those units are shipped or delivered, depending on contractual terms, and revenue allocated to PCS and extended warranties will be recognized ratably over
the service period.

For multiple element arrangements that were entered into prior to January 1, 2010 and that include
NES System and/or Element Manager software, the Company defers the recognition of all revenue until all software required under the arrangement has been delivered to the customer. Once the software has been delivered, the Company recognizes revenues
for the Hardware and software royalties upon customer acceptance of the Hardware based on a constant ratio of meters to data concentrators, which is determined on a contract-by-contract basis. To the extent actual deliveries of either meters or data
concentrators is disproportionate to the expected overall ratio for any given arrangement, revenue for the excess meters or data concentrators is deferred until such time as additional deliveries of meters or data concentrators has occurred.
Revenues for PCS on the NES System and Element Manager software, as well as for extended warranties on its NES Hardware products, are recognized ratably over the associated service period, which generally commences upon the later of the delivery of
all software, or the customers acceptance of any given Hardware shipment.

Deferred Revenue and Deferred Cost of
Goods Sold

Deferred revenue and deferred cost of goods sold result from transactions where the Company has shipped
product or performed services for which all revenue recognition criteria have not yet been met. Deferred cost of goods sold related to deferred product revenues includes direct product costs and applied overhead. Deferred cost of goods sold related
to deferred service revenues includes direct labor costs and applied overhead. Once all revenue recognition criteria have been met, the deferred revenues and associated cost of goods sold are recognized.

2. Financial Instruments

The Companys financial instruments consist of cash equivalents, short-term investments, accounts
receivable, accounts payable, and lease financing obligations. The carrying value of the Companys financial instruments approximates fair value. Financial instruments that potentially subject the Company to concentrations of credit risk
consist principally of investments, which are classified as either cash equivalents or short-term, and trade receivables. With respect to its investments, the Company has an investment policy that limits the amount of credit exposure to any one
financial institution and restricts placement of the Companys investments to financial institutions independently evaluated as highly creditworthy. With respect to its trade receivables, the Company performs ongoing credit evaluations of each
of its customers financial condition. For a customer whose credit worthiness does not meet the Companys minimum criteria, the Company may require partial or full payment prior to shipment. Alternatively, prior to shipment, customers may
be required to provide the Company with an irrevocable letter of credit or arrange for some other form of coverage to mitigate the risk of uncollectibility, such as a bank guarantee. Additionally, the Company establishes an allowance for doubtful
accounts and sales return allowances based upon factors surrounding the credit risk of specific customers, historical trends, and other available information.

On a recurring
basis, the Company measures certain of its financial assets, namely its cash equivalents and available-for-sale investments, at fair value. The Company does not have any financial liabilities measured at fair value on a recurring basis. The fair
value of the Companys financial assets measured at fair value on a recurring basis was determined using the following inputs at September 30, 2010 (in thousands):

approximately $16.0 million are classified as cash equivalents, while the remaining $51.9 million are classified as short-term investments. Of the $67.9 million of fixed income available-for-sale securities at December 31, 2009,
approximately $5.0 million are classified as cash equivalents, while the remaining $62.9 million are classified as short-term investments. Cash equivalents consist of either investments with remaining maturities of three months or less at
the date of purchase, or money market funds for which the carrying amount is a reasonable estimate of fair value.

ECHELON CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS(Continued)

(Unaudited)





The Companys
fixed income available-for-sale securities consist of U.S. government securities with a minimum and weighted average credit rating of A-1+. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in
active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. However, the Company classifies all of its fixed income
available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of the Companys financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are
corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. Our procedures include controls to ensure that appropriate fair values are recorded such as comparing
prices obtained from multiple independent sources.

As of September 30, 2010, the Companys available-for-sale
short-term investments had contractual maturities from ten to twelve months and an average remaining term to maturity of six months. As of September 30, 2010, the amortized cost basis, aggregate fair value, and gross unrealized holding gains
and losses of the Companys short-term investments by major security type were as follows (in thousands):

Market values were determined for each individual security in the investment portfolio. The Company reviews
its investments on a regular basis to evaluate whether or not any of them have experienced an other-than-temporary decline in fair value. In performing its review, the Company considers factors such as the length of time and extent to which the
market value has been less than the cost, the financial condition and near-term prospects of the issuer, and the Companys intent to sell (or whether it is more likely than not that the Company will be required to sell) the investment before
recovery of the investments amortized cost basis. If the Company believes that an other-than-temporary decline exists, that investment is written down to fair value. As of September 30, 2010, none of the Companys investments
had any material unrealized losses.

For the three and nine months ended September 30, 2010 and 2009, the diluted net loss per share
calculation is equivalent to the basic net loss per share calculation as there were no potentially dilutive stock options due to the Companys net loss position. The number of stock options, stock appreciation rights, and restricted stock units
excluded from this calculation for the three and nine months ended September 30, 2010 and 2009 was 7,952,175 and 7,413,512, respectively.

Stock Award
Activity

The total intrinsic value of options exercised during the three and nine months ended September 30, 2010
was approximately $89,000 and $749,000, respectively. The total intrinsic value of options exercised during the three and nine months ended September 30, 2009 was approximately $630,000 and $839,000, respectively. The intrinsic value is
calculated as the difference between the market value on the date of exercise and the exercise price of the shares.

The total
fair value of restricted stock units (RSUs) vested and released during the three and nine months ended September 30, 2010 was approximately $1.0 million and $5.0 million, respectively. The total fair value of RSUs vested and
released during the three and nine months ended September 30, 2009 was approximately $1.4 million and $2.2 million, respectively. The fair value is calculated by multiplying the fair market value of the Companys stock on the vesting date
by the number of shares vested.

Equity Compensation Expense for RSUs with Financial- Based Performance Vesting Requirements

As of September 30, 2010, there were 512,439 non-vested RSUs (with a grant date fair value of approximately
$3.8 million) that were subject to certain financial-based performance requirements that must be achieved before vesting can occur. Of these 512,439 non-vested RSUs, 31,250 (that were issued in October 2006 with a grant date fair value of
approximately $263,000) contain financial-based performance conditions that must be achieved by October 2010; 116,189 (that were issued in May 2009 with a grant date fair value of approximately $859,000) contain financial-based performance
conditions that must be achieved by May 2014, and the remaining 365,000 RSUs (that were issued in August 2010 with a grant date fair value of approximately $2.7 million) contain financial-based performance conditions that must be achieved by April
2015.

Through September 30, 2010, cumulative compensation expense of $619,000 associated with the 116,189 RSUs granted
in May 2009 and the 365,000 RSUs granted in August 2010 has been recognized because the Company believes it is probable that the associated financial performance requirements will be achieved. If such requirements are not met, no compensation cost
will be recognized and any recognized compensation cost will be reversed. For these 481,189 awards that are considered probable of achievement, the unearned compensation expense of $2.9 million is expected to be recognized over estimated service
periods ranging from 8 months to 3.3 years. To the extent the Companys estimate of the timing of achievement of the performance requirements changes in the future, the timing of recognition of the related compensation expense may change. No
compensation expense has been recognized associated with the remaining 31,250 RSUs granted in October 2006 as the financial performance requirements for these awards were not met.

5. Significant Customers:

The Company markets its
products and services throughout the world to original equipment manufacturers (OEMs) and systems integrators in the building, industrial, transportation, utility/home, and other automation markets. During the three and nine months ended
September 30, 2010 and 2009, the Company had two customers that accounted for a significant portion of its revenues: EBV Electronik GmbH (EBV), the Companys primary distributor of its LONWORKS® Infrastructure products in Europe, and Eltel Networks A/S (Eltel), a value added reseller of the
Companys NES products. For the three and nine months ended September 30, 2010 and 2009, the percentage of the Companys revenues attributable to sales made to these customers was as follows:

Of the percentage
of sales made to EBV, approximately 0.4% and 0.7% for the three and nine months ended September 30, 2009, respectively, related to sales of components the Company sold to EBV, which EBV in turn sold to one of Enels third party meter
manufacturers. Elsewhere in this document, those sales are reported as Enel Project revenues. The Companys contract with EBV, which has been in effect since 1997 and has been renewed annually thereafter, expires in December 2011. Please refer
to Note 11, Related Parties, for additional information regarding the Companys agreements with Enel.

6. Commitments and
Contingencies:

Legal Actions

In April 2009, the Company received notice that the receiver for two companies that filed for the Italian law equivalent of bankruptcy protection in May 2004, Finmek Manufacturing SpA and Finmek Access
SpA (collectively, the Finmek Companies), had filed a lawsuit under an Italian claw back law in Padua, Italy against the Company, seeking the return of approximately $16.7 million in payments received by the Company in the
ordinary course of business for components sold by the Company to the Finmek Companies prior to the bankruptcy filing. The Finmek Companies were among Enels third party meters manufacturers, and from time to time through January 2004, the
Company sold components to the Finmek Companies that were incorporated into the electricity meters that were manufactured by the Finmek Companies and sold to Enel SpA for the Enel Project. The Company believes that the Italian claw back law is not
applicable to its transactions with the Finmek Companies, and the claims of the Finmek Companies receiver are without merit.

From time to time, in the ordinary course of business, the Company may be subject to other legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of
third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, the Company makes a provision for a liability when it is both probable that a
liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other
information and events pertaining to a particular case. While the Company believes it has adequately provided for such contingencies as of September 30, 2010, the amounts of which were immaterial, it is possible that the Companys results
of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

Line of Credit

The Company maintains a $10.0 million line of credit with its primary bank, which expires on July 1, 2011. The letter of credit contains certain financial covenants requiring the Company to maintain
an overall minimum tangible net worth level and to maintain a minimum level of liquid assets. As of September 30, 2010, the Company was in compliance with these covenants. As of September 30, 2010, the Companys primary bank had
issued, against the line of credit, two standby letters of credit totaling $147,000. Other than issuing standby letters of credit, the Company has never drawn against the line of credit, nor have amounts ever been drawn against the standby letters
of credit issued by the bank.

7. Inventories:

Inventories are stated at the lower of cost (first-in, first-out) or market and include material, labor and manufacturing overhead. When required, provisions are made to reduce excess and obsolete
inventories to their estimated net realizable value. Inventories consist of the following (in thousands):

of the completion of certain of the design and development activities and is reflected in accrued liabilities as detailed above. The $300,000 will be used to offset current period Product Development expenses in the period during which the
associated milestone is completed. The remaining $3.9 million has been used to offset related Product Development expenses incurred during the nine months ended September 30, 2010, $1.9 million of which was used to offset Product Development
expenses during the three months ended September 30, 2010.

9. Segment Disclosure:

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 his direct reports.

The Company operates in one principal industry segment, its reportable
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 provide the infrastructure and support required to implement and deploy open, interoperable, control network solutions. For the electric utility industry, the Company has developed an advanced metering infrastructure system called the
Networked Energy Services (NES) System. The NES System provides a two-way information and control path between the utility and its customer, which enables utilities to reduce operating costs; improve customer service; offer multiple tariff
plans, including time-of-use metering and prepay metering; promote energy efficiency; better utilize distribution assets; improve grid quality and reliability; control loads and reduce peak demand; and respond more rapidly to changing customer and
regulatory requirements. All of the Companys products either incorporate or operate with the Neuron® Chip
and/or the LonWorks protocol. The Company also provides a range of services to its customers that consist of technical support, training courses covering its LonWorks network technology and products, and custom software development. In total, the
Company offers a wide ranging set of 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 operates in three main geographic areas: the Americas; Europe, Middle East and Africa (EMEA); and Asia
Pacific/Japan (APJ). Each geographic area provides products and services to the Companys customers located in the respective region. The Companys long-lived assets include property and equipment, goodwill, loans to certain
key employees, purchased technology, and deposits on its leased facilities. Long-lived assets are attributed to geographic areas based on the country where the assets are located. As of September 30, 2010 and December 31, 2009,
substantially all of the Companys long-lived assets were domiciled in the United States.

For information regarding the Companys major customers, please refer to Note 5, Significant Customers.

10. Income Taxes:

The provision for income taxes for the three months ended September 30, 2010 and 2009 was $170,000 and $155,000, respectively. The provision for income taxes for the nine months ended
September 30, 2010 and 2009 was $252,000 and $31,000, respectively. The difference between the statutory rate and the Companys effective tax rate is primarily due to the impact of foreign taxes, changes in the valuation allowance on
deferred tax assets, and changes in the accruals related to unrecognized tax benefits.

As of September 30, 2010 and
December 31, 2009, the Company had gross unrecognized tax benefits of approximately $4.3 million and $4.6 million, respectively, of which $796,000 and $802,000, respectively, if recognized, would impact the effective tax rate on income from
continuing operations. The Companys policy is to recognize interest and/or penalties related to unrecognized tax benefits in income tax expense. As of September 30, 2010 and December 31, 2009, the Company had accrued $206,000 and
$224,000, respectively, for interest and penalties. The $18,000 reduction in accrued interest and penalties during the nine months ended September 30, 2010 was primarily attributable to the expiration of the statute of limitations in certain
foreign jurisdictions, partially offset by amounts accrued for the current year.

11. Related Parties:

The law firm of Wilson Sonsini Goodrich & Rosati, P.C. acts as principal outside counsel to our company. Mr. Sonsini, a
director of our company, is a member of Wilson Sonsini Goodrich & Rosati, P.C.

From time to time, our Executive
Chairman, M. Kenneth Oshman, uses his private plane or charter aircraft for Company business for himself and any employees that accompany him. In August 2008, our Board of Directors approved a reimbursement arrangement whereby our company will
reimburse Mr. Oshman for 50% of the costs incurred for his private plane or charter aircraft travel used while on company business. Such costs include flight charges (subject to any discounted rate that may apply), fuel, fuel surcharges,
landing fees, crew costs and related expenses. During the three months ended September 30, 2010, we recognized a total of approximately $45,000 in expenses pursuant to the reimbursement arrangement, all of which has been included in general and
administrative expenses in the Condensed Consolidated Statements of Operations. During the nine months ended September 30, 2010, we recognized a total of approximately $95,000 in expenses pursuant to the reimbursement arrangement, all of which
has been included in general and administrative expenses in the Condensed Consolidated Statements of Operations. The Audit Committee of the Companys Board of Directors regularly reviews these reimbursements.

In November 2009,
our Board of Directors approved a similar reimbursement arrangement for our then President and Chief Executive Officer, Robert R. Maxfield, whereby our company would reimburse Mr. Maxfield for 50% of the costs incurred for charter aircraft used
while on company business. Alternatively, if Mr. Maxfield uses his private plane while on company business, we would reimburse him for the cost of an equivalent first class ticket on a commercial flight. During the three months ended
September 30, 2010, there were no expenses incurred associated with Mr. Maxfields reimbursement arrangement. During the nine months ended September 30, 2010, we recognized a total of approximately $1,000 in expense pursuant to
the reimbursement arrangement, all of which has been included in general and administrative expenses in the Condensed Consolidated Statements of Operations.

In June 2000, we entered into a stock purchase agreement with Enel pursuant to which Enel purchased 3.0 million newly issued shares of our common stock for $130.7 million. The closing of this stock
purchase occurred on September 11, 2000. At the closing, Enel had agreed that it would not, except under limited circumstances, sell or otherwise transfer any of those shares for a specified time period. That time period expired
September 11, 2003. To our knowledge, Enel has not disposed of any of its 3.0 million shares. Under the terms of the stock purchase agreement, Enel has the right to nominate a member of our board of directors. A representative of Enel is
not presently serving on our board.

At the time we entered into the stock purchase agreement with Enel, we also entered into
a research and development agreement with an affiliate of Enel (the R&D Agreement). Under the terms of the R&D Agreement, we cooperated with Enel to integrate our LONWORKS technology into Enels
remote metering management project in Italy, the Contatore Elettronico. We completed the sale of our components and products for the deployment phase of the Contatore Elettronico project during 2005. During 2006, we supplied Enel and its designated
manufacturers with limited spare parts for the Contatore Elettronico system. In October 2006, we entered into a new development and supply agreement and a software enhancement agreement with Enel. Under the development and supply agreement, Enel and
its contract manufacturers purchase additional electronic components and finished goods from us. Under the software enhancement agreement, we provide software enhancements to Enel for use in its Contatore Elettronico system. The development and
supply agreement expires in December 2011, and the software enhancement agreement expires in December 2010, although delivery of products and services can extend beyond those dates and the agreements may be extended under certain circumstances.

For the three months ended September 30, 2010 and 2009, the Company recognized revenue from products and services sold
to Enel and its designated manufacturers of approximately $1.5 million and $1.2 million, respectively. For the nine months ended September 30, 2010 and 2009, the Company recognized revenue from products and services sold to Enel and its
designated manufacturers of approximately $3.5 million and $4.2 million, respectively. As of September 30, 2010, and December 31, 2009, $761,000 and $6.1 million, respectively, of the Companys total accounts receivable balance
related to amounts owed by Enel and its designated manufacturers.

On October 29, 2001, the Company loaned Russell
Harris, its Senior Vice President of Operations, $1,000,000 in connection with his principal residence. Mr. Harris issued to the Company a promissory note secured by residential real estate. The note bore interest at the rate of 4.5% per
annum, compounded monthly. The interest that accrued under the note was due and payable in monthly installments over the nine year term of the note, and the principal was due and payable on October 29, 2010. The principal was paid in full by
Mr. Harris in June 2009. During the three and nine months ended September 30, 2009, interest paid by Mr. Harris was $0 and $22,000, respectively. While it was outstanding, the terms of this loan were never amended.

|ITEM 2. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto included elsewhere
in this Quarterly Report. The following discussion contains predictions, estimates, and other forward-looking statements that involve a number of risks and uncertainties about our business. These statements may be identified by the use of words such
as we believe, expect, anticipate, intend, plan, goal, continues, may, and similar expressions. In addition, forward-looking statements include
statements that refer to projections of our future financial performance, our anticipated growth and trends in our businesses, and other characterizations of future events or circumstances. Such statements are based on our current expectations and
could be affected by the uncertainties and risk factors described throughout this filing and particularly in the Factors That May Affect Future Results of Operations section. All forward-looking statements in this document are based on
information available to us as of the date hereof and we assume no obligation to update any such forward-looking statements. Our actual results may differ materially.

EXECUTIVE OVERVIEW

Echelon Corporation was
incorporated in California in February 1988 and reincorporated in Delaware in January 1989. We are based in San Jose, California, and maintain offices in eleven foreign countries throughout Europe and Asia. We develop, market, and sell system and
network infrastructure products that enable everyday devicessuch as air conditioners, appliances, electricity meters, light switches, thermostats, and valvesto be made smart and inter-connected. Working together, products and systems
equipped with our technology can monitor and save energy, lower costs, improve productivity and enhance service, quality, safety, and convenience. We offer these hardware and software products and related services to OEMs and systems integrators in
the building, industrial, transportation, utility/home, and other automation markets.

For the last several years, we have
been investing heavily in the development of hardware and software products for the advanced metering infrastructure, or AMI, market. These AMI products are used by the electric utility industry in their distribution and metering systems, and are
components of what is commonly referred to as the smart grid. To date, we have generated revenues of approximately $219.7 million from these investments. We refer to this revenue as networked energy services, or NES, revenue. We also
sell certain of our products to Enel and certain suppliers of Enel for use in Enels Contatore Elettronico electricity meter management project in Italy. We refer to Echelons revenue derived from sales to Enel and Enels designated
manufacturers as Enel Project revenue. We refer to all other revenue as LONWORKS Infrastructure, or LWI, revenue. We also provide a variety of technical training courses related to our products and the underlying
technology. Some of our customers also rely on us to provide customer support on a per-incident or term contract basis.

Our
total revenues increased by 14.6% during the third quarter of 2010 as compared to the same period in 2009. While our gross margins increased by 2.5 percentage points between the two periods, due primarily to improved margins on our NES products, our
operating expenses also increased between the two periods. The result was a net loss for the third quarter of 2010 that was $375,000 less than the loss generated during the same period in 2009. For the nine months ended September 30, 2010,
total revenues increased by 12.0% as compared to the same period in 2009, while gross margins improved slightly and operating expenses increased by 2.5%. The increase in revenues was the primary driver behind a decrease of $3.0 million, or 10.7%, in
our net loss for the nine month period.

The following tables provide an overview of key financial metrics for the three and
nine months ended September 30, 2010 and 2009 that our management team focuses on in evaluating our financial condition and operating performance (in millions, except percentages).

| |  |  | Net revenues: As noted above, our total net revenues increased by $3.4 million, or 14.6%, during the third quarter of 2010 as compared to the
same period in 2009. This was driven by a 13.3% increase in NES revenues, a 14.0% increase in LWI revenues, and a 31.6% increase in Enel Project revenues. For the nine months ended September 30, 2010, our total net revenues increased by $7.7
million, or 12.0%, as compared to the same period in 2009. This was driven by a 17.4% increase in NES revenues and an 11.0% increase in LWI revenues, partially offset by a 16.4% reduction in Enel Project revenues.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

While we have experienced modest improvement in both our NES and LWI revenues during the first half of 2010, we continue to believe that
our revenue levels have been adversely affected by the severe economic downturn that began in late 2008 and has continued since then. Utilities are the ultimate customer for our NES products. We believe that utilities have limited their capital
expenditures in response to reduced cash flow arising from the worldwide recession. In addition, in the United States we believe that utilities have further delayed decisions pending the distribution of stimulus awards from the United States
Department of Energy as well as regulatory obstacles they have faced in moving forward with their smart grid roll-outs. With respect to the LWI product line, many of our customers produce products used in commercial or industrial buildings. The
markets for these products were adversely affected by the recession. However, we have seen strength in energy saving markets such as demand response. The reduction in our Enel Project revenues during the nine months ended September 30, 2010 as
compared to the same period in 2009 was primarily due to an anticipated decrease in the level of orders placed by Enels meter manufacturers for metering kits under the 2006 development and supply agreement.



| |  |  | Gross margin: Our gross margin improved by 2.5 percentage points during the third quarter of 2010 as compared to the same period in 2009. For
the nine months ended September 30, 2010, gross margins improved by 0.8 percentage points. Excluding the impact of non-cash stock-based compensation charges, gross margins improved by 1.7% during the third quarter as compared to the same period
in 2009, from 45.6% in 2009 to 47.3% in 2010. This increase was primarily due to improved gross margins generated from sales of our NES products. For the nine months ended September 30, 2010, as compared to the same period in 2009, gross
margins excluding the impact of non-cash stock-based compensation charges remained relatively unchanged.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Operating expenses: Our operating expenses increased by 7.6% during the third quarter of 2010 as compared to the same period in 2009, and
increased by 2.5% during the nine months ended September 30, 2010 as compared to the same period in 2009. Excluding the impact of non-cash stock-compensation charges, operating expenses increased by 12.0% during the third quarter, from $14.7
million in the third quarter of 2009 to $16.4 million in the third quarter of 2010. For the nine months ended September 30, 2010, as compared to the same period in 2009, operating expenses excluding non-cash stock-based compensation charges
increased by approximately 5.4%, from $45.4 million in 2009 to $47.8 million in 2010.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Net loss:Our net loss decreased by 4.6% and 10.7% for the three and nine month periods ended September 30, 2010, respectively, as compared
to the same periods in 2009. Excluding the impact of non-cash stock-compensation charges, our net loss increased by $190,000, or 4.2% during the third quarter of 2010 as compared to the same period in 2009. For the nine months ended
September 30, 2010, our net loss excluding the impact of non-cash stock compensation charges decreased by $1.6 million, or 9.2%. The reduction in our net loss for the nine months ended September 30, 2010 as compared to the same period in
2009 was primarily attributable to increased revenues in 2010.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Cash, cash equivalents, and short-term investments: During the first nine months of 2010, our cash, cash equivalent, and short-term investment
balance decreased by 7.3%, from $80.1 million at December 31, 2009 to $74.3 million at September 30, 2010. This $5.8 million reduction was primarily the result of $2.5 million of cash used in financing activities, $1.6 million of cash used
in operating activities, and capital expenditures of $1.4 million.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe that, during the remainder of
2010, we will continue to face a challenging economic environment in the markets we serve. However, we remain cautiously optimistic that the modest NES and LWI revenue increases we have experienced so far during 2010 will continue during the fourth
quarter. This belief is dependent on many macro-economic factors, including market improvement for the products our LWI customers sell that incorporate our technology, resolution of United States stimulus funding, and timely resolution of regulatory
processes. Our management team remains focused on working to ensure that our company is properly positioned to capitalize on existing customer relationships, as well as new opportunities as they become available. For example, we continue to invest
strategically in the development of new technologies and products to increase our share of the network infrastructure market, including technologies and products specifically aimed at the smart grid and other green initiatives. We also
continue to enhance our sales and marketing efforts in a variety of ways, including adding to our existing base of third party value added resellers, initiating new sales channel programs, and hiring new employees to cover critical areas.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Note 1, Significant Accounting Policies of Notes to Consolidated Financial Statements in our Annual Report
on Form 10-K for the year ended December 31, 2009, which we filed with the Securities and Exchange Commission in March 2010, describes the significant accounting policies and methods used in the preparation of our consolidated financial
statements. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and
liabilities. On an on-going basis, we evaluate our estimates, including those related to our revenues, stock-based compensation, allowance for doubtful accounts, inventories, and commitments and contingencies. We base our estimates on historical
experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these
estimates under different assumptions or conditions.

With the exception of a change in our accounting policy for revenue
recognition, which is more fully described below, during the three and nine months ended September 30, 2010 there were no material changes to our critical accounting policies or in the matters for which we make critical accounting estimates in
the preparation of our condensed consolidated financial statements as compared to those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2009.

Revenue Recognition.Our revenues are derived from the sale and license of our products and to a lesser extent, from fees associated with training, technical support, and custom software design
services offered to our customers. Product revenues consist of revenues from hardware sales and software licensing arrangements. Service revenues consist of product technical support (including software post-contract support services), training, and
custom software development services.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has
occurred, the sales price is fixed or determinable, collectability is probable, and there are no post-delivery obligations. For non-distributor hardware sales, including sales to third party manufacturers, these criteria are generally met at the
time of shipment. For sales made to our distributor partners, these criteria are generally met at the time the distributor sells the products through to its end-use customer.



20



---



We account for
the rights of return, price protection, rebates, and other sales incentives offered to distributors of our products as a reduction in revenue. With the exception of sales to distributors, the Companys customers are generally not entitled to
return products for a refund. For sales to distributors, due to contractual rights of return and other factors that impact our ability to make a reasonable estimate of future returns and other sales incentives, revenues are not recognized until the
distributor has shipped our product to the end customer.

In most instances involving large-scale
deployments, our NES System products are sold as part of multiple element arrangements. These arrangements may require us to deliver our NES System products and services over an extended period of time. In October 2009, the FASB amended the
accounting standards for multiple deliverable revenue arrangements to:



| |  |  | provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration
should be allocated;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | require an entity to allocate revenue in an arrangement using its best estimated selling price (BESP) of deliverables if a vendor does not
have vendor-specific objective evidence (VSOE) of selling price or third-party evidence (TPE) of selling price; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------

We elected to early adopt this accounting guidance January 1, 2010 on a prospective basis for
applicable transactions originating or materially modified after December 31, 2009.

As noted above, our multiple
deliverable revenue arrangements are primarily related to sales of our NES System products, which may include, within a single arrangement, electricity meters and data concentrators (collectively, the Hardware); NES System software;
Element Manager software; post-contract customer support (PCS) for the NES System and Element Manager software; extended warranties for the Hardware; and, occasionally, specified enhancements or upgrades to software used in the NES
System. For arrangements originating or materially modified after December 31, 2009, with the exception of the NES System software, each of these deliverables is considered a separate unit of accounting. The NES System software functions
together with an electricity meter to deliver its essential functionality and any related software license fee is charged for on a per meter basis. Therefore, the NES System software and an electricity meter are combined and considered a single unit
of accounting. The Element Manager software is not considered to be part of an electricity meters essential functionality and, therefore, Element Manager software and any related PCS continues to be accounted for under industry specific
software revenue recognition guidance. However, all other NES system deliverables are no longer within the scope of industry specific software revenue recognition guidance.

We allocate revenue to each element in a multiple-element arrangement based upon the elements relative selling price. We determine the selling price for each deliverable using VSOE of selling price
or TPE of selling price, if it exists. If neither VSOE nor TPE of selling price exists for a deliverable, we use our BESP for that deliverable. Since the use of the residual method has been eliminated under the new accounting standards, any
discounts we offer are allocated to each of the deliverables. Revenue allocated to each element is then recognized when the basic revenue recognition criteria is met for the respective element.

Consistent with our methodology under previous accounting guidance, if available, we determine VSOE of fair value for each element based
on historical stand-alone sales to third parties or from the stated renewal rate for the elements contained in the initial contractual arrangement. We currently estimate the selling prices for our PCS and extended warranties based on VSOE of fair
value.

In many instances, we are not currently able to obtain VSOE of fair value for all deliverables in an arrangement with
multiple elements. This may be due to the fact that we infrequently sell each element separately or that we do not price products within a narrow range. When VSOE cannot be established, we attempt to estimate the selling price of each element based
on TPE. TPE would consist of our competitors prices for similar deliverables when sold separately. However, in general, our offerings contain significant differentiation from our competition such that the comparable pricing of products with
similar functionality cannot be obtained. Furthermore, we are unable to reliably determine the stand-alone selling prices for similar products of our competitors. Therefore, we typically are not able to obtain TPE of selling price.



21



---



When we are unable to
establish a selling price using VSOE or TPE, which is generally the case for the Hardware and certain specified enhancements or upgrades to our NES software, we use our BESP in determining the allocation of arrangement consideration. The objective
of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized
offerings.

We establish pricing for our products and services by considering multiple factors including, but not limited to,
geographies, market conditions, competitive landscape, internal costs, gross margin objectives, and industry pricing practices. The determination of pricing also includes consultation with and formal approval by our management, taking into
consideration our go-to-market strategy. These pricing practices apply to both our Hardware and software products.

Based on
our analysis of pricing stated in contractual arrangements for our Hardware products in historical multiple-element transactions and, to a lesser extent, historical standalone transactions, we have concluded that we typically price our Hardware
within a narrow range of discounts when compared to the price listed on our standard pricing grid for similar deliverables (i.e., similar configuration, volume, geography, etc.). Therefore, we have determined that, for our current Hardware for which
VSOE or TPE is not available, our BESP is generally comprised of prices based on a narrow range of discounts from pricing stated in our pricing grid.

When establishing BESP for our specified software enhancements or upgrades, we consider multiple factors including, but not limited to, the relative value of the features and functionality being delivered
by the enhancement or upgrade as compared to the value of the software product to which the enhancement or upgrade relates, as well as our pricing practices for NES System PCS packages, which may include rights to the specified enhancements or
upgrades.

We regularly review VSOE and have established a review process for TPE and BESP. We maintain internal controls over
the establishment and updates of these estimates. There were no material impacts during the three and nine months ended September 30, 2010 resulting from changes in VSOE, TPE, or BESP, nor do we expect a material impact from such changes in the
near term.

Total net revenues as reported and unaudited pro forma total net revenues that would have been reported during the
three and nine months ended September 30, 2010, if the transactions entered into or materially modified after December 31, 2009 were subject to previous accounting guidance, are shown in the following table (in thousands):



|                                                                 |  |             |        |  |                                                                   |   |        |

|Total net revenues for the nine months ended September 30, 2010  |  | $           | 72,227 |  |                                                                   | $ | 70,542 | 

The impact to total
net revenues during the three and nine months ended September 30, 2010 resulting from the adoption of the new accounting guidance was to net product revenues, and related solely to sales of our NES products. For both the three and nine months
ended September 30, 2010, the impact was related primarily to the fact that, under the new accounting guidance, we recorded revenue on certain transactions for which the previous accounting guidance would have required deferral. These
transactions involved multiple element arrangements where software upgrades had not yet been delivered as of September 30, 2010. Under the new accounting guidance, we determined the BESP for the software upgrades and deferred the relative
selling price of these items accordingly. Under the previous accounting guidance, all revenue related to these transactions would have been deferred as we did not have VSOE of fair value for the undelivered items.

As it relates to the timing and pattern of revenue recognition for NES product sales in the future, the new accounting guidance has had a
significant effect on total net revenues for transactions entered into or materially modified after December 31, 2009, and we expect this trend to continue. This expectation is primarily due to the fact that we do not currently have VSOE of
fair value for most of our NES product offerings, which often resulted in deferral of revenue as discussed below. In the future, for NES arrangements subject to the new revenue recognition guidance, revenue allocated to meters and data concentrators
will be recognized as those units are shipped or delivered, depending on contractual terms, and revenue allocated to PCS and extended warranties will be recognized ratably over the service period.

For multiple element
arrangements that were entered into prior to January 1, 2010 and that include NES System and/or Element Manager software, we defer the recognition of all revenue until all software required under the arrangement has been delivered to the
customer. Once the software has been delivered, we recognize revenues for the Hardware and software royalties upon customer acceptance of the Hardware based on a constant ratio of meters to data concentrators, which is determined on a
contract-by-contract basis. To the extent actual deliveries of either meters or data concentrators is disproportionate to the expected overall ratio for any given arrangement, revenue for the excess meters or data concentrators is deferred until
such time as additional deliveries of meters or data concentrators has occurred. Revenues for PCS on the NES System and Element Manager software, as well as for extended warranties on its NES Hardware products, are recognized ratably over the
associated service period, which generally commences upon the later of the delivery of all software, or the customers acceptance of any given Hardware shipment.

The $3.4 million increase
in total revenues for the quarter ended September 30, 2010 as compared to the same period in 2009 was the result of a $1.5 million increase in NES revenues, a $1.5 million increase in LWI revenues, and a $369,000 increase in Enel Project
revenues. The $7.7 million increase in total revenues for the nine months ended September 30, 2010 as compared to the same period in 2009 was the result of a $4.7 million increase in NES revenues and a $3.7 million increase in LWI
revenues, partially offset by a $681,000 decrease in Enel Project revenues.

During the three and nine
months ended September 30, 2010 and 2009, our NES revenues were derived primarily from a relatively small number of customers who have undertaken large-scale deployments of our NES System products. These deployments generally come to fruition
after an extended and complex sales process, and each is relatively substantial in terms of its revenue potential. They vary significantly from one another in terms of, among other things, the overall size of the deployment, the duration of time
over which the products will be sold, the mix of products being sold, the timing of delivery of those products, and the ability to modify the timing or size of those projects. This relative uniqueness among each deployment results in significant
variability and unpredictability in our NES revenues.

The increases in NES revenues of $1.5 million and $4.7 million during
the three and nine month periods ended September 30, 2010, respectively, as compared to the same periods in 2009 were due to an overall increase in the level of large-scale deployments of our NES System products. In particular, these increases
were primarily attributable to increased shipments of our NES products for projects in Denmark. In addition, as discussed more fully in the section titled Critical Accounting Policies and Estimates earlier in this section, our NES
revenues during the three and nine months ended September 30, 2010, were approximately $772,000 and $1.7 million, respectively, higher than they would have been if we had applied the revenue recognition standards in effect during the prior year
due to our January 1, 2010 adoption of new accounting guidance for multiple element arrangements.

recognize revenue on shipments of our NES products depends on several factors, including, but not limited to, the impact on delivery dates of any modifications to existing shipment schedules included in the contracts that have been awarded to us
thus far, and certain contractual provisions, such as customer acceptance. In addition, the complex revenue recognition rules relating to products such as our NES System will likely require us to defer some or all of the revenue associated with
shipments of these products until certain conditions are met in a future period. Although we adopted new accounting guidance for multiple element arrangements during the first quarter of 2010 (which is discussed more fully in the section titled
Critical Accounting Policies and Estimates earlier in this section), that guidance will only apply to transactions entered into or materially modified after December 31, 2009. In the meantime, orders booked prior to 2010 will
continue to be accounted for under previous revenue recognition guidance. For those orders, our ability to recognize revenue associated with sales of our NES products will continue to be affected by the factors discussed in our NES revenues
discussion in our Annual Report on Form 10-K for the year ended December 31, 2009. As of September 30, 2010 and December 31, 2009, approximately $3.6 million and $5.2 million, respectively, of NES revenue was deferred. Of the $3.6
million of deferred revenue at September 30, 2010, approximately $1.2 million of it relates to revenue that will be accounted for under previous revenue recognition guidance while the remaining $2.4 million relates to revenue that will be
accounted for under the new revenue recognition guidance.

We also expect that some foreign utilities will require us to price
our NES products in the respective utilitys local currency, which will expose us to foreign currency risk. To date, we have not hedged any of these foreign currency risks because the amounts involved have been immaterial. In most cases, in the
event of a significant contract award that requires us to price our NES products in the customers local currency, we intend to hedge this foreign currency risk so long as we can secure forward currency contracts that are reasonably priced and
that are consistent with the scheduled deliveries for that project.

In addition, we will face foreign currency exposures from
the time we submit any foreign currency denominated bid until the award of a contract by the utility (the bid to award term). This bid to award term can often exceed several months. If a utility awards us a contract that gives the
utility the right to exercise options for additional supply in the future, we would also be exposed to foreign currency risk until such time as these options, if any, were exercised. We may decide that it is too expensive to hedge the foreign
currency risks during the bid to award term or for any unexercised options. Any resulting adverse foreign currency fluctuations could significantly harm our revenues, results of operations, and financial condition.

Lastly, our NES revenues have historically been concentrated with a relatively few customers. During the years ended December 31,
2009, 2008, and 2007, approximately 85.4%, 93.1%, and 91.6%, respectively, of our NES revenues were attributable to five customers. While our NES customers will change over time, given the nature of the NES market, we expect our future NES revenues
will continue to be concentrated among a limited number of customers.

During 2009, our NES revenues decreased by
approximately 28.1% as compared to 2008. We believe this reduction was due, at least in part, to the sudden and severe worldwide economic slowdown that began in late 2008 and continued through 2009. As a result of the recession, utilities have
experienced reduced cash flows, which we believe has caused them to limit their capital expenditures. In addition, the economic downturn has had a particularly detrimental effect on the credit markets, both in the United States and abroad, which
play a key role in a utilitys decision to move forward with a large-scale deployment, as such efforts frequently require the utility to secure financing for the project. We also believe that the American Recovery and Reinvestment Act of 2009,
which was enacted in early 2009, caused many U.S. utilities to postpone their plans to move forward with their large-scale AMI deployments. This was due to the fact that, once the stimulus program was announced, utilities throughout the United
States applied for stimulus funds in order to offset a portion of their projects expected costs.

During the third
quarter of 2010, we announced the Echelon Control System (ECoS), a new open software platform for intelligent distributed control of the smart grid. ECoS will run throughout the edge of the grid on a new Echelon product, the Edge Control Node (ECN)
7000 series of open and extensible hardware solutions. We also announced that Duke Energy will be the first customer for ECoS and the ECN. While both ECoS and the ECN currently remain under development, we expect to ship beta units to Duke Energy
for testing later this year. We expect to begin shipping final versions of the new products during the latter part of 2011, at which point revenues associated with the new products will commence.

We currently expect that our 2010 NES revenues will increase modestly over 2009 levels, in part due to our expectation that world-wide
macro-economic conditions and associated credit markets, which were severely impacted by the recession, will improve. We also remain cautiously optimistic that the stimulus effect of the American Recovery and Reinvestment Act of 2009, particularly
as it relates to those funds allocated to AMI initiatives, will begin to be realized towards the end of 2010.

Our LWI revenues are
primarily comprised of sales of our hardware and software products, and to a lesser extent, revenues we generate from our customer support and training offerings. The $1.5 million increase in LWI revenue for the quarter ended September 30, 2010
as compared to the same period in 2009 was due to increases of $701,000, $604,000, and $240,000 from the Americas, EMEA, and APJ regions, respectively. Within the LWI family of products, the $1.5 million increase was primarily attributable to an
increase in sales of our Control and Connectivity products, particularly our transceiver products, and to a lesser extent, sales of our SmartServer products.

The $3.7 million increase in LWI revenues for the nine months ended September 30, 2010 as compared to the same period in 2009 was due to increases of $2.4 million, $900,000, and $334,000 in the
Americas, APJ, and EMEA regions, respectively. Within the LWI family of products, the $3.7 million increase was again primarily attributable to an increase in sales of our Control and Connectivity products, and to a lesser extent, sales of our
SmartServer products.

Our future LWI revenues will continue to be subject to fluctuations in the exchange rates between the
United States dollar and the foreign currencies in which we sell our LWI products and services. In general, if the dollar were to weaken against these currencies, our revenues from those foreign currency sales, when translated into United States
dollars, would increase. Conversely, if the dollar were to strengthen against these currencies, our revenues from those foreign currency sales, when translated into United States dollars, would decrease. The extent of this exchange rate fluctuation
increase or decrease will depend on the amount of sales conducted in these currencies and the magnitude of the exchange rate fluctuation from year to year. The portion of our LWI revenues conducted in currencies other than the U.S. dollar,
principally the Japanese Yen, was about 7.3% for the nine months ended September 30, 2010 and 6.8% for the same period in 2009. To date, we have not hedged any of these foreign currency risks. We do not currently expect that, in the near
future, the amount of our LWI revenues conducted in these foreign currencies will fluctuate significantly from prior year levels. Given the historical and expected future level of sales made in foreign currencies, we do not currently plan to hedge
against these currency rate fluctuations. However, if the portion of our revenues conducted in foreign currencies were to grow significantly, we would re-evaluate these exposures and, if necessary, enter into hedging arrangements to help minimize
these risks.

As with our NES revenues, we currently expect our full year 2010 LWI revenues will increase modestly over
amounts generated in 2009, due primarily to our expectation of improved macro-economic conditions in certain of the markets we serve.

In October 2006, we
entered into two agreements with Enel, a development and supply agreement and a software enhancement agreement. Under the development and supply agreement, Enel is purchasing additional metering kit and data concentrator products from us. Under the
software enhancement agreement, we are providing software enhancements to Enel for use in its Contatore Elettronico system. Enel Project revenue recognized during the three and nine month periods ended September 30, 2010 and 2009 related
primarily to shipments under the 2006 development and supply agreement, and to a lesser extent, from revenues attributable to the software enhancement agreement.

The $369,000 increase
in Enel Project revenues during the three months ended September 30, 2010 as compared to the same period in 2009 was due to a $578,000 increase in revenues generated from metering kits sold, partially offset by a $209,000 reduction in software
enhancement service revenues. The $681,000 decrease in Enel Project revenues during the nine months ended September 30, 2010 as compared to the same period in 2009 was due to a $708,000 reduction in metering kit revenues, partially offset by a
$27,000 increase in software enhancement service revenues. Enel Project revenues will fluctuate from quarter-to-quarter depending on the number of metering kit and data concentrator products purchased, as well as the amount of software enhancement
services provided.

The development and supply agreement expires in December 2011, and the software enhancement agreement
expires in December 2010, although delivery of products and services can extend beyond that date and the agreements may be extended under certain circumstances. We currently expect that revenues from the Enel project during 2010 will be
significantly lower than those generated in 2009.

We sell our products to Enel and its designated manufacturers in U.S.
dollars. Therefore, the associated revenues are not subject to foreign currency risks.

Gross profit is equal
to revenues less cost of goods sold. Cost of goods sold for product revenues includes direct costs associated with the purchase of components, subassemblies, and finished goods, as well as indirect costs such as allocated labor and overhead; costs
associated with the packaging, preparation, and shipment of products; and charges related to excess and obsolete inventory reserves, warranty costs, and purchase price variances. Cost of goods sold for service revenues consists of employee-related
costs such as salaries and fringe benefits as well as other direct and indirect costs incurred in providing training, customer support, and custom software development services. Gross margin is equal to gross profit divided by revenues.

The 2.5 percentage point increase in gross margin during the third quarter of 2010 as compared to the same period in 2009 was due
primarily to an improvement in overall gross margins for our NES products.

Our future gross margins will continue to be
affected by several factors, including, but not limited to: overall revenue levels, changes in the mix of products sold, periodic charges related to excess and obsolete inventories, warranty expenses, introductions of cost reduced versions of our
NES and LWI products, changes in the average selling prices of the products we sell, purchase price variances, and fluctuations in the level of indirect overhead spending that is capitalized in inventory. In addition, the impact of foreign exchange
rate fluctuations and labor rates may affect our gross margins in the future. We currently outsource the manufacturing of most of our products requiring assembly to CEMs located primarily in China. To the extent labor rates were to rise, or to the
extent the dollar were to weaken against the Chinese currency, or other currencies used by our CEMs, our costs for the products they manufacture could rise, which would negatively affect our gross margins. Lastly, many of our products, particularly
our NES products, contain significant amounts of certain commodities, such as copper and cobalt. Prices for these commodities have been volatile, which in turn have caused fluctuations in the prices we pay for the products in which they are
incorporated.

Product development
expenses consist primarily of payroll and related expenses for development personnel, facility costs, expensed material, fees paid to third party service providers, depreciation and amortization, and other costs associated with the development of
new technologies and products.

The decreases of $412,000 and $2.0 million in product development expenses during the three
and nine month periods ended September 30, 2010, respectively, as compared to the same periods in 2009 were primarily due to the fact that product development expenses of $1.9 million and $3.9 million for the three and nine months ended
September 30, 2010, respectively, were offset by contractually guaranteed payments (as such term is defined by generally accepted accounting principles) by a third party (also discussed in Note 8  Accrued Liabilities in the
accompanying condensed consolidated financial statements included in Part 1 of this report). Partially offsetting the decreases were incremental product development expenses we incurred in performing this work. We currently expect this arrangement
will continue during the remainder of 2010 and into 2011. During this time, we expect our product development expenses will fluctuate from quarter to quarter. These fluctuations will be driven by both the amount of contractually guaranteed payments
earned by us during the respective quarter, since the payments are used to offset current period product development expenses incurred, and any incremental expenses associated with this project that we incur in the respective period. Therefore,
while the arrangement is in effect, our future product development expenses could be higher or lower than levels reported in 2009.

Another factor contributing to the decrease in product development expenses for both the three and nine month periods ended September 30, 2010, as compared to the same periods in 2009, was a
reduction in non-cash equity compensation charges, which decreased by $396,000 between the two three month periods and by $1.1 million between the two nine month periods.

In April 2010, we announced that our Board of Directors had approved a restoration of salary for all of our employees who had been affected by the structured salary reduction we implemented in 2009. The
salary restoration took effect on May 1, 2010. Accordingly, we expect that salary expense for our product development personnel during the remainder of 2010 will increase modestly from levels we recorded in 2009.

Sales and marketing
expenses consist primarily of payroll and related expenses for sales and marketing personnel, including commissions to sales personnel, travel and entertainment, facilities costs, advertising and product promotion, and other costs associated with
our sales and support offices.

The $724,000 increase in sales and marketing expenses for the quarter ended September 30,
2010 as compared to the same period in 2009 was primarily due to a $402,000 increase in compensation related expenses, and to a lesser extent, by a $230,000 increase marketing expenses. The increase in compensation expenses was primarily
attributable to increased commission expenses. The increase in marketing expenses was primarily related to a new product launch effort conducted during the third quarter of 2010.

The $1.8 million
increase in sales and marketing expenses for the nine months ended September 30, 2010 as compared to the same period in 2009 was primarily due to a $1.2 million increase in compensation related expenses, and to a lesser extent, by increases in
travel and entertainment and marketing expenses. As with the quarter-over-quarter increase in compensation related expenses, the $1.2 million increase between the two nine month periods was primarily due to an increase in commission expenses, and to
a lesser extent by an increase in headcount in our sales and marketing organization.

Our sales personnel were not affected by
the structured salary reduction program we implemented in May 2009, although our U.S. based marketing personnel were. Therefore, our future compensation related sales and marketing expenses will not be affected as significantly as a result of the
May 2010 salary restoration discussed above. However, our future sales and marketing expenses will continue to be affected by fluctuations in exchange rates between the U.S. dollar and the foreign currencies where we operate. If the United States
dollar were to weaken against these currencies, our sales and marketing expenses could increase. Conversely, if the dollar were to strengthen against these currencies, it would have a favorable impact on our sales and marketing expenses.

General and administrative
expenses consist primarily of payroll and related expenses for executive, finance, and administrative personnel, professional fees for legal and accounting services rendered to the company, facility costs, insurance, and other general corporate
expenses.

The $1.0 million increase in general and administrative expenses during the quarter ended September 30, 2010
as compared to the same period in 2009 was primarily attributable to a $500,000 increase in compensation and related expenses, of which $155,000 related to an increase in non-cash equity compensation charges. The increase in compensation related
expenses was due in part to our April 2010 announcement that our Board of Directors had approved a restoration of salary for all of our employees who had been affected by the structured salary reduction we implemented in 2009. The salary restoration
took effect on May 1, 2010. Accordingly, we expect our compensation related general and administrative expenses for the remainder of 2010 will increase modestly from levels we recorded in 2009. To a lesser extent, a $382,000 increase in fees
paid to our outside counsel, independent accountants, and other third party service providers also contributed to the quarter-over-quarter increase.

The $1.5 million increase in general and administrative expenses during the nine months ended September 30, 2010 as compared to the same period in 2009 was primarily attributable to a $737,000
increase in compensation and related expenses, of which $229,000 related to an increase in non-cash equity compensation charges. In addition, a $603,000 increase in fees paid to our outside counsel, independent accountants, and other third party
service providers also contributed to the year-over-year increase.

Interest and other
income (expense), net primarily reflects interest earned by our company on cash and short-term investment balances as well as foreign exchange translation gains and losses related to short-term intercompany balances.

The $468,000 reduction in interest and other income (expense), net during the quarter ended September 30, 2010 as compared to the
same period in 2009 was primarily attributable to a $475,000 increase in foreign currency translation losses between the two periods. The $538,000 increase in interest and other income, net during the nine months ended September 30, 2010 as
compared to the same period in 2009 was primarily attributable to a $725,000 increase in foreign currency translation gains between the two periods, partially offset by a $189,000 reduction in interest income. The changes in foreign currency
translation gains and losses are due to our foreign currency denominated short-term intercompany balances. We account for translation gains and losses associated with these balances by reflecting these amounts as either other income or loss in our
consolidated statements of operations. During periods when the U.S. dollar weakens in value against these foreign currencies, as it did during the third quarter of 2010, the associated translation losses negatively impact other income. Conversely,
when the U.S. dollar strengthens, as it did during the first nine months of 2010, the resulting translation gains favorably impact other income. The reduction in interest income is primarily the result of a reduction in our average invested cash
balance between the periods coupled with reductions in the weighted average yield on our investment portfolio.

We do not
currently anticipate interest income on our investment portfolio will improve significantly during 2010 as we expect interest rates to remain historically low. Future gains or losses associated with translating our foreign currency denominated
short-term intercompany balances will depend on exchange rates in effect at the time of translation.

The monthly rent payments
we make to our lessor under the lease agreements for our San Jose headquarters site are recorded in our financial statements partially as land lease expense, with the remainder being allocated to principal and interest on the financing liability.
Interest expense on lease financing obligations reflects the portion of our monthly lease payments that is allocated to interest expense.

The decreases of $25,000 and $71,000 in interest expense on lease financing obligations during the three and nine month periods ended September 30, 2010 as compared to the same periods in 2009 were a
result of the nature of this expense. As with any amortizing fixed rate loan, payments made earlier in the term of the loan are comprised primarily of interest expense with little being allocated to principal repayment. Payments made later in the
term of the loan, however, have an increasing proportion of principal repayment, with less being attributable to interest expense. Accordingly, as we continue to make payments in accordance with our lease obligation, we expect a higher proportion of
the payments we make in the future will be allocated to principal repayment and less will be allocated to interest expense.

The income tax expense for
the quarters ended September 30, 2010 and 2009 was $170,000 and $155,000, respectively. The income tax expense for the nine month periods ended September 30, 2010 and 2009 was $252,000 and $31,000, respectively. The difference between the
statutory rate and our effective tax rate is primarily due to the impact of foreign taxes, changes in the valuation allowance on deferred tax assets, and changes in the accruals related to unrecognized tax benefits.

OFF-BALANCE-SHEET ARRANGEMENTS AND OTHER
CONTRACTUAL OBLIGATIONS

Off-Balance-Sheet Arrangements. We have not entered into any
transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained interests, derivative instruments, or other contingent arrangements that expose our company to material continuing risks, contingent liabilities,
or any other obligation under a variable interest in an unconsolidated entity that provides financing, liquidity, market risk, or credit risk support to us.

Lease Commitments. In December 1999, we entered into a lease agreement with a real estate developer for our existing corporate headquarters in San Jose, California. In October 2000,
we entered into a second lease agreement with the same real estate developer for an additional building at our headquarters site. These leases were scheduled to expire in 2011 and 2013, respectively.

Effective June 2008, the building leases were amended resulting in an extension of the lease term for both buildings through March 2020.
The extended leases require minimum lease payments through March 2020 totaling approximately $48.9 million. Both leases permit us to exercise an option to extend the respective lease for two sequential five-year terms. In addition, the amended
leases eliminated our requirement to provide the landlord with security deposits totaling $6.2 million, which we had previously satisfied through the issuance of standby letters of credit (LOCs). As of June 30, 2008, the previously
issued LOCs had been returned to the bank that issued them and were cancelled.

In addition, we lease facilities under
operating leases for our sales, marketing, and product development personnel located elsewhere within the United States and in ten foreign countries throughout Europe and Asia, including a land lease for accounting purposes associated with our
corporate headquarters facilities. These operating leases expire on various dates through 2020, and in some instances are cancelable with advance notice. Lastly, we also lease certain equipment and, for some of our sales personnel, automobiles.
These operating leases are generally less than five years in duration.

Purchase Commitments. We utilize several contract
manufacturers who manufacture and test our products requiring assembly. These contract manufacturers acquire components and build product based on demand information supplied by us in the form of purchase orders and demand forecasts. These purchase
orders and demand forecasts generally cover periods that range from one to six months, and in some cases, up to one year. We also obtain individual components for our products from a wide variety of individual suppliers. We generally acquire these
components through the issuance of purchase orders, and in some cases through demand forecasts, both of which cover periods ranging from one to nine months.

We also utilize purchase orders when procuring capital equipment, supplies, and services necessary for our day-to-day operations. These purchase orders generally cover periods ranging up to twelve months,
but in some instances cover a longer duration.

Indemnifications.
In the normal course of business, we provide indemnifications of varying scope to customers against claims of intellectual property infringement made by third parties arising from the use of our products. Historically, costs related to these
indemnification provisions have not been significant. However, we are unable to estimate the maximum potential impact of these indemnification provisions on our future results of operations.

As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences
while the officer or director is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officers or directors lifetime. The maximum potential amount of future
payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that would enable us to recover a portion of any future amounts paid. We believe the estimated fair
value of these indemnification agreements in excess of the applicable insurance coverage is minimal.

Royalties. We have
certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a U.S. dollar amount per unit shipped or a percentage of the underlying revenue. Royalty expense, which is recorded
under our cost of products revenue in our condensed consolidated statements of operations, was approximately $120,000 during the quarter ended September 30, 2010, and $99,000 for the same period in 2009, and $477,000 for the nine months ended
September 30, 2010, and $291,000 for the same period in 2009.

We will continue to be obligated for royalty payments in
the future associated with the shipment and licensing of certain of our products. While we are currently unable to estimate the maximum amount of these future royalties, such amounts will continue to be dependent on the number of units shipped or
the amount of revenue generated from these products.

Taxes. We conduct our operations in many tax jurisdictions throughout the
world. In many of these jurisdictions, non-income based taxes such as property taxes, sales and use taxes, and value-added taxes are assessed on Echelons operations in that particular location. While we strive to ensure compliance with these
various non-income based tax filing requirements, there have been instances where potential non-compliance exposures have been identified. In accordance with generally accepted accounting principles, we make a provision for these exposures when it
is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. To date, such provisions have been immaterial, and we believe that, as of September 30, 2010, we have adequately provided for such
contingencies. However, it is possible that our results of operations, cash flows, and financial position could be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where we conduct our operations.

Legal Actions. In April 2009, the Company received notice that the receiver for two companies that filed for the Italian
law equivalent of bankruptcy protection in May 2004, Finmek Manufacturing SpA and Finmek Access SpA (collectively, the Finmek Companies), had filed a lawsuit under an Italian claw back law in Padua, Italy against Echelon,
seeking the return of approximately $16.7 million in payments received by Echelon in the ordinary course of business for components we sold to the Finmek Companies prior to the bankruptcy filing. The Finmek Companies were among Enels third
party meters manufacturers, and from time to time through January 2004, we sold components to the Finmek Companies that were incorporated into the electricity meters that were manufactured by the Finmek Companies and sold to Enel SpA for the Enel
Project. We believe that the Italian claw back law is not applicable to our transactions with the Finmek Companies, and the claims of the Finmek Companies receiver are without merit.

From time to time, in the ordinary course of business, we are subject to legal proceedings, claims, investigations, and other
proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, we make a provision for
a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements,
rulings, advice of legal counsel, and other information and events pertaining to a particular case. While we believe we have adequately provided for such contingencies as of September 30, 2010, it is possible that our results of operations,
cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

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, although during the years 2002 through 2004, we were also able to finance our operations through operating cash flow. From inception through September 30, 2010, we raised $294.0 million from the sale of preferred stock
and common stock, including the exercise of stock options and warrants from our employees and directors.

In March and August
2004, March 2006, and February 2007, our board of directors approved a stock repurchase program, which authorized us to repurchase up to 3.0 million shares of our common stock, in accordance with Rule 10b-18 and other applicable laws,
rules and regulations. Since inception, we have repurchased a total of 2,204,184 shares under the program at a cost of $16.1 million. The stock repurchase program expired in March 2008.

In April 2008, our board of directors approved a new stock repurchase program, which authorizes us to repurchase up to 3.0 million
shares of our common stock, in accordance with Rule 10b-18 and other applicable laws, rules and regulations. There were no repurchases under the new stock repurchase program during the quarter and nine months ended September 30, 2010. Since
inception, we have repurchased a total of 750,000 shares under the program at a cost of $8.9 million. As of September 30, 2010, 2,250,000 shares were available for repurchase. This stock repurchase program will expire in April 2011.

The following table presents selected financial information as of September 30, 2010, and for each of the last three fiscal years
(dollars in thousands):

As of
September 30, 2010, we had $74.3 million in cash, cash equivalents, and short-term investments, a decrease of $5.8 million as compared to December 31, 2009. Historically, our primary source of cash, other than stock sales, has been
receipts from revenue, and to a lesser extent, proceeds from the exercise of stock options and warrants by our employees and directors. Our primary uses of cash have been cost of product revenue, payroll (salaries, commissions, bonuses, and
benefits), general operating expenses (costs associated with our offices such as rent, utilities, and maintenance; fees paid to third party service providers such as consultants, accountants, and attorneys; travel and entertainment; equipment and
supplies; advertising; and other miscellaneous expenses), acquisitions, capital expenditures, and purchases under our stock repurchase program.

Cash flows from operating activities. Cash flows from operating activities have historically been driven by net income (loss) levels;
adjustments for non-cash charges such as stock-based compensation; depreciation and amortization; changes in accrued investment income; and fluctuations in operating asset and liability balances. Net cash used in operating activities was $1.6
million for the nine months ended September 30, 2010, a decrease in cash outflows of approximately $9.4 million as compared to the same period in 2009. During the nine months ended September 30, 2010, net cash used in operating activities
was primarily the result of our net loss of $25.3 million, partially offset by stock-based compensation expenses of $9.3 million, changes in our operating assets and liabilities of $9.3 million, and depreciation and amortization expense of $5.0
million. The primary components of the $9.3 million change in our operating assets and liabilities were a $8.9 million decrease in accounts receivable, a $1.3 million increase in accrued liabilities, a $972,000 decrease in other current assets, and
an $806,000 reduction in deferred cost of goods sold; the benefits of which were partially offset by a $1.3 million decrease in deferred revenues, a $1.2 million increase in inventories, and a $119,000 decrease in accounts payable. Accounts
receivable decreased primarily as a result of reduced revenues during the third quarter of 2010 as compared to the fourth quarter of 2009. During the quarter ended September 30, 2010, total revenues were $27.1 million compared to $38.8 million
during the quarter ended December 31, 2009. Accrued liabilities increased primarily as a result of a $1.2 million increase in customer deposits, of which $300,000 related to funding received for design and development of a new product prior to
completion of certain development efforts. Other current assets decreased primarily due to a reduction in unbilled receivables. Deferred cost of goods sold decreased in conjunction with a decrease in deferred revenues. Inventories increased in
preparation for increased revenue levels in the fourth quarter of 2010 as compared to the first quarter of 2010.

During the nine months
ended September 30, 2009, net cash used in operating activities was primarily the result of our net loss of $28.3 million, partially offset by stock-based compensation expenses of $10.7 million, depreciation and amortization expense of $4.8
million, and changes in our operating assets and liabilities of $1.8 million. The primary components of the $1.8 million decrease in our operating assets and liabilities were an $8.8 million decrease in accounts receivable and a $1.6 million
decrease in other current assets, the benefits of which were partially offset by a $3.8 million decrease in accounts payable, a $3.2 million increase in inventories, a $934,000 reduction in accrued liabilities, and a $687,000 reduction in deferred
revenues. Accounts receivable decreased primarily as a result of reduced revenues during the third quarter of 2009 as compared to the fourth quarter of 2008. During the quarter ended September 30, 2009, total revenues were $23.7 million
compared to $36.8 million during the quarter ended December 31, 2008. Other current assets decreased due to the receipt of $1.9 million from one of our CEMs for non-trade receivable amounts due our company for materials they purchased from us.
Accounts payable decreased due to the timing of expenditures during the second quarter of 2009. Inventories increased due in part to the sudden world-wide economic slowdown that occurred during the fourth quarter of 2008, as well as due to our
transition between CEMs which began in 2008 and continued through the first quarter of 2009. During this transition, we were required to purchase significant amounts of raw material inventory, much of which remained on our balance sheet as of
September 30, 2009. In addition, inventories increased during the third quarter of 2009 in preparation for a higher level of product shipments during the fourth quarter of 2009. Accrued liabilities decreased due primarily to a $643,000
reduction in customer deposits.

Cash flows from investing activities. Cash flows from investing activities have
historically been driven by transactions involving our short-term investment portfolio, capital expenditures, changes in our long-term assets, and acquisitions. Net cash provided by investing activities was $9.6 million for the nine months ended
September 30, 2010, a $30.2 million increase in cash inflows as compared to the same period in 2009. During the nine months ended September 30, 2010, net cash provided by investing activities was primarily the result of proceeds from
maturities and sales of available-for-sale short-term investments of $56.9 million, partially offset by purchases of available-for-sale short-term investments of $45.9 million and capital expenditures of $1.4 million. During the nine months ended
September 30, 2009, net cash used in investing activities was primarily the result of purchases of available-for-sale short-term investments of $99.8 million and capital expenditures of $1.3 million, partially offset by proceeds from maturities
and sales of available-for-sale short-term investments of $79.4 million and a reduction in other long-term assets of $1.0 million. The $1.0 million reduction in other long-term assets was due to the repayment of a loan made to one of our key
employees.

Cash flows from financing activities. Cash flows from financing activities have historically been driven by the
proceeds from issuance of common and preferred stock offset by transactions under our stock repurchase programs and principal payments on our lease financing obligations. Net cash used in financing activities was $2.5 million for the nine months
ended September 30, 2010, a $2.5 million increase in cash outflows as compared to the same period in 2009. During the nine months ended September 30, 2010, net cash used in financing activities was primarily the result of $1.8 million
worth of shares repurchased from employees for payment of employee taxes on vesting of performance shares and upon exercise of stock options and $1.2 million in principal payments on our building lease financing obligations, partially offset by
proceeds of $537,000 from the exercise of stock options by our employees. During the nine months ended September 30, 2009, net cash provided by financing activities was primarily the result of proceeds of $1.8 million from the exercise of stock
options by our employees, partially offset by $1.1 million in principal payments on our building lease financing obligations and $699,000 worth of shares repurchased from employees for payment of employee taxes on vesting of performance shares and
upon exercise of stock options.

We use well-regarded investment managers to manage our invested cash. Our portfolio of
investments managed by these investment managers is primarily composed of highly rated U.S. government securities, and to a lesser extent, U.S. corporate obligations and money market funds. All investments are made according to guidelines and within
compliance of policies approved by the Audit Committee of our Board of Directors.

We maintain a $10.0 million line of credit
with our primary bank, which expires on July 1, 2011. The letter of credit contains certain financial covenants requiring us to maintain an overall minimum tangible net worth level and to maintain a minimum level of liquid assets. As of
September 30, 2010, we were in compliance with these covenants. As of September 30, 2010, our primary bank has issued, against the line of credit, two standby letters of credit totaling $147,000. Other than issuing standby letters of
credit, we have never drawn against the line of credit, nor have amounts ever been drawn against the standby letters of credit issued by the bank.

In the future, our
cash reserves may be used to strategically acquire other companies, products, or technologies that are complementary to our business. In addition, our combined cash, cash equivalents, and short-term investments balances could be negatively affected
by various risks and uncertainties, including, but not limited to, the risks detailed later in this discussion in the section title Factors That May Affect Future Results of Operations. For example, any continued weakening of
economic conditions or changes in our planned cash outlay could negatively affect our existing cash reserves.

Based on our
current business plan and revenue prospects, we believe that our existing cash reserves will be sufficient to meet our projected working capital and other cash requirements for at least the next twelve months. However, we currently expect that our
combined cash, cash equivalent, and short-term investment balance will decline during 2010. We expect that cash requirements for our payroll and other operating costs will continue at about existing levels. We also expect that we will continue to
acquire capital assets such as computer systems and related software, office and manufacturing equipment, furniture and fixtures, and leasehold improvements, as the need for these items arises. In the event that we require additional financing, 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.

RELATED PARTY TRANSACTIONS

The law firm of Wilson Sonsini Goodrich & Rosati, P.C. acts as principal outside counsel to our company. Mr. Sonsini, a
director of our company, is a member of Wilson Sonsini Goodrich & Rosati, P.C.

From time to time, our Executive
Chairman, M. Kenneth Oshman, uses his private plane or charter aircraft for Company business for himself and any employees that accompany him. In August 2008, our Board of Directors approved a reimbursement arrangement whereby our company will
reimburse Mr. Oshman for 50% of the costs incurred for his private plane or charter aircraft travel used while on company business. Such costs include flight charges (subject to any discounted rate that may apply), fuel, fuel surcharges,
landing fees, crew costs and related expenses. During the three months ended September 30, 2010, we recognized a total of approximately $45,000 in expenses pursuant to the reimbursement arrangement, all of which has been included in general and
administrative expenses in the Condensed Consolidated Statements of Operations. During the nine months ended September 30, 2010, we recognized a total of approximately $95,000 in expenses pursuant to the reimbursement arrangement, all of which
has been included in general and administrative expenses in the Condensed Consolidated Statements of Operations. The Audit Committee of the Companys Board of Directors regularly reviews these reimbursements.

In November 2009, our Board of Directors approved a similar reimbursement arrangement for our then President and Chief Executive Officer,
Robert R. Maxfield, whereby our company would reimburse Mr. Maxfield for 50% of the costs incurred for charter aircraft used while on company business. Alternatively, if Mr. Maxfield uses his private plane while on company business, we
would reimburse him for the cost of an equivalent first class ticket on a commercial flight. During the three months ended September 30, 2010, there were no expenses incurred associated with Mr. Maxfields reimbursement arrangement.
During the nine months ended September 30, 2010, we recognized a total of approximately $1,000 in expense pursuant to the reimbursement arrangement, all of which has been included in general and administrative expenses in the Condensed
Consolidated Statements of Operations.

In June 2000, we entered into a stock purchase agreement with Enel pursuant to which
Enel purchased 3.0 million newly issued shares of our common stock for $130.7 million. The closing of this stock purchase occurred on September 11, 2000. At the closing, Enel had agreed that it would not, except under limited
circumstances, sell or otherwise transfer any of those shares for a specified time period. That time period expired September 11, 2003. To our knowledge, Enel has not disposed of any of its 3.0 million shares. Under the terms of the stock
purchase agreement, Enel has the right to nominate a member of our board of directors. A representative of Enel is not presently serving on our board.

At the time we entered
into the stock purchase agreement with Enel, we also entered into a research and development agreement with an affiliate of Enel (the R&D Agreement). Under the terms of the R&D Agreement, we cooperated with Enel to integrate our
LONWORKS technology into Enels remote metering management project in Italy, the Contatore Elettronico. We completed the sale of our components and products for the deployment phase of the Contatore Elettronico
project during 2005. During 2006, we supplied Enel and its designated manufacturers with limited spare parts for the Contatore Elettronico system. In October 2006, we entered into a new development and supply agreement and a software enhancement
agreement with Enel. Under the development and supply agreement, Enel and its contract manufacturers purchase additional electronic components and finished goods from us. Under the software enhancement agreement, we provide software enhancements to
Enel for use in its Contatore Elettronico system. The development and supply agreement expires in December 2011, and the software enhancement agreement expires in December 2010, although delivery of products and services can extend beyond those
dates and the agreements may be extended under certain circumstances.

For the three months ended September 30, 2010 and
2009, we recognized revenue from products and services sold to Enel and its designated manufacturers of approximately $1.5 million and $1.2 million, respectively. For the nine months ended September 30, 2010 and 2009, we recognized revenue from
products and services sold to Enel and its designated manufacturers of approximately $3.5 million and $4.2 million, respectively. As of September 30, 2010, and December 31, 2009, $761,000 and $6.1 million, respectively, of our total
accounts receivable balance related to amounts owed by Enel and its designated manufacturers.

On October 29, 2001, we
loaned Russell Harris, our Senior Vice President of Operations, $1,000,000 in connection with his principal residence. Mr. Harris issued to us a promissory note secured by residential real estate. The note bore interest at the rate of
4.5% per annum, compounded monthly. The interest that accrued under the note was due and payable in monthly installments over the nine year term of the note, and the principal was due and payable on October 29, 2010. The principal was paid
in full by Mr. Harris in June 2009. During the three and nine months ended September 30, 2009, interest paid by Mr. Harris was $0 and $22,000, respectively. While it was outstanding, the terms of this loan were never amended.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

Interested persons should carefully consider the risks described below in evaluating our company. 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 would likely decline. Before deciding to purchase, hold or sell our common stock, you should carefully consider the risks described in this section. This section should be read in
conjunction with the condensed consolidated financial statements and accompanying notes thereto, and Managements Discussion and Analysis of Financial Condition and Results of Operations included in this Quarterly Report on Form 10-Q.

Our NES revenues may not be predictable, which could cause volatility in the price of our stock.

We and our partners sell our NES System to utilities. For several reasons, sales cycles with utility companies can be extended and
unpredictable. Utilities generally have complex budgeting, purchasing, and regulatory processes that govern their capital spending. In addition, in many instances, a utility may require one or more field trials of an automated meter infrastructure
(AMI) system (such as one based on our NES System) before moving to a volume deployment. There is also generally an extended development and integration effort required in order to incorporate a new technology into a utilitys existing
infrastructure. In addition, in the U.S., utilities have delayed deployments as they have sought incentives under the U.S. economic stimulus legislation. A number of other factors may also need to be addressed before the utility decides to engage in
a full-scale deployment of our NES System, including:



| |  |  | regulatory factors, standards compliance, or internal utility requirements that may affect the AMI system or the timing of its deployment;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



36



---



| |  |  | the time it takes for utilities to evaluate multiple competing bids, negotiate terms, and award contracts for large scale metering system deployments;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the deployment schedule for projects undertaken by our utility or systems integrator customers; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | delays in installing, operating, and evaluating the results of an AMI field trial that is based on our NES System.
| | - |  | ------------------------------------------------------------------------------------------------------------------

As a result, we can often spend up to two years working either directly or through a reseller to make a sale to a utility. At the end of
that lengthy sales process, there is no guarantee that we will be selected by the utility.

In addition, shipment of NES
products to a particular jurisdiction or customer is generally dependent on either obtaining regulatory approval for the NES meter or other products from a third party for the relevant jurisdiction, or satisfying the customers internal testing
requirements, or both. This certification approval process is often referred to as homologation. Further, shipment of NES products into some jurisdictions requires our contract manufacturers to pass certain tests and meet various standards
related to the production of our NES meters. Failure to receive any such approval on a timely basis or at all, or failure to maintain any such approval, would have a material adverse impact on our ability to ship our NES System products, and
would therefore have an adverse affect on our results of operations and our financial condition.

Once a utility decides to
move forward with a large-scale deployment of an AMI project that is based on our NES System, the timing of and our ability to recognize revenue on our NES System product shipments will depend on several factors. These factors, some of which may not
be under our control, include shipment schedules that may be delayed or subject to modification, other contractual provisions, such as customer acceptance of all or any part of the AMI system, and our ability to manufacture and deliver quality
products according to expected schedules. In addition, the complex revenue recognition rules relating to products such as our NES System may also require us to defer some of our NES revenues until certain conditions, such as the acceptance of
software deliverables, are met in a future period.

As a consequence of these long sales cycles, unpredictable delay factors,
and complex revenue recognition policies, our ability to predict the amount of NES revenues that we may expect to recognize in any given fiscal quarter is likely to be limited. As NES revenues account for an increasing percentage of our overall
revenues, we are likely to have increasing difficulty in projecting our overall financial results. Our inability to accurately forecast future revenues is likely to cause our stock price to be volatile.

Sales of our NES System may fail to meet our financial targets, which would harm our results of operations.

We have invested and intend to continue to invest significant resources in the development and sales of our NES System, including our
newest product for utilities, the Edge Control Node. Our long-term financial goals include expectations for a reasonable return on these investments. However, to date the revenues generated from sales of our NES System products have not yielded
gross margins in line with our long term goals for this product line, although our operating expenses have increased significantly.

In order to achieve our financial targets, we must meet the following objectives:



| |  |  | Increase market acceptance of our NES System products in order to increase NES revenues;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | Increase gross margin from our NES revenues by continuing to reduce the cost of manufacturing our NES System products, while at the same time managing
manufacturing cost pressures associated with commodity prices and foreign exchange fluctuations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Manage the manufacturing transition to reduced-cost NES products; and
| | - |  | ---------------------------------------------------------------------



| |  |  | Manage our operating expenses to a reasonable percentage of revenues.
| | - |  | ---------------------------------------------------------------------

We cannot assure you that we will meet any or all of these objectives to the extent necessary to achieve our financial goals and, if we
fail to achieve our goals, our results of operations are likely to be harmed.

Adverse changes in general economic
or political conditions in any of the major countries in which we do business could adversely affect our business or operating results.

Our business can be affected by a number of factors that are beyond our control, such as general geopolitical, economic, and business conditions. The continuing economic slowdown and the uncertainty over
its breadth, depth and duration continue to put pressure on the global economy and have a negative effect on our business. Further, the worldwide financial and credit crisis continues to limit the availability of liquidity and credit to fund the
continuation and expansion of business operations worldwide. The shortage of liquidity and credit, combined with losses in worldwide equity markets, is contributing to the continuation of the world-wide economic recession.

While we do not currently depend on access to the credit markets to finance our operations, there can be no assurance that the
deteriorated state of the financial markets will not impair our ability to obtain financing in the future, including, but not limited to, our ability to draw on funds under our existing credit facilities or our ability to incur indebtedness or sell
equity if that became necessary or desirable. If we were not able to obtain additional financing when needed, our ability to invest in additional research and development resources and sales and marketing resources could be adversely affected, which
could hinder our ability to sell competitive products into our markets on a timely basis.

In addition, there could be a
number of follow-on effects from the credit crisis on our business, such as the insolvency of certain of our key customers, which could impair our distribution channels, or result in the inability of our customers to obtain credit to finance
purchases of our products.

Also, the U.S. economic stimulus legislation enacted in 2009 caused potential customers to delay
their purchases until they determined if the economic incentives would become available to them under the legislation, and if so, the conditions under which the stimulus funds would be granted.

This uncertainty about future economic and political conditions makes it difficult for us to forecast operating results and to make
decisions about future investments. We continue to see the effects of the economic slowdown on both our NES and LWI revenues. If economic activity in the U.S. and other countries economies remains weak, many customers may continue to delay,
reduce, or even eliminate their purchases of networking technology products. This could result in continued reductions in sales of our products, longer sales cycles, slower adoption of our technologies, increased price competition, and increased
exposure to excess and obsolete inventory. For example, distributors could decide to further reduce inventories of our products. Also, the inability to obtain credit could cause a utility to postpone its decision to move forward with a large scale
deployment of our NES System. If conditions in the global economy, U.S. economy or other key vertical or geographic markets we serve remain uncertain or continue to be weak, we would experience material negative impacts on our business, financial
condition, results of operations, cash flow, capital resources, and liquidity.

We are exposed to credit risk and payment delinquencies on
our accounts receivable, and this risk has been heightened during the current decline in economic conditions.

We only
recognize revenue when we believe collectability is reasonably assured. However, almost none of our outstanding accounts receivables are covered by collateral or credit insurance. In addition, our standard terms and conditions permit payment within
a specified number of days following shipment of product, or in some cases, after the customers acceptance of our products. While we have procedures to monitor and limit exposure to credit risk on our receivables, there can be no assurance
such procedures will effectively limit our credit risk and avoid losses. Additionally, when one of our resellers makes a sale to a utility, we face further credit risk, and we may defer revenue, due to the fact that the reseller may not be able to
pay us until it receives payment from the utility. This risk could become more magnified during a particular fiscal period if the resellers facing credit issues represent a significant portion of our accounts receivable during that period. As
economic conditions change and worsen, certain of our direct or indirect customers may face liquidity concerns and may be unable to satisfy their payment obligations to us or our resellers on a timely basis or at all, which would have a material
adverse effect on our financial condition and results of operations.

Because we depend on a limited
number of key suppliers and in certain cases, a sole supplier, the failure of any key supplier to produce timely and compliant products could result in a failure to ship products, which would harm our results of operations and financial position.

Our future success will depend significantly on our ability to timely manufacture our products cost effectively, in
sufficient volumes, and in accordance with quality standards. For most of our products requiring assembly, we rely on a limited number of contract electronic manufacturers (CEMs), principally Jabil and TYCO. These CEMs procure material and assemble,
test, and inspect the final products to our specifications. This strategy involves certain risks, including reduced control over quality, costs, delivery schedules, availability of materials, components, finished products, and manufacturing yields.
As a result of these and other risks, our CEMs could demand price increases for manufacturing our products. In addition, CEMs can experience turnover, instability, and lapses in manufacturing or component quality, exposing us to additional risks as
well as missed commitments to our customers.

We also maintain manufacturing agreements with a limited number of semiconductor
manufacturers for the production of key products, including those used in our NES System. The Neuron Chip is an important component that we and our customers use in control network devices. In addition to those sold by Echelon, the Neuron Chip is
currently manufactured and distributed by two providers, Toshiba and Cypress Semiconductor. Toshiba has informed us that it does not intend to renew its Neuron Chip agreement with us, which expired in January 2010. However, we have agreed with
Toshiba that Toshiba will continue to accept orders for Neuron Chips from its customers through September 2011 for deliveries through December 2012. In the meantime, we are implementing a plan to allow for a smooth migration path for Toshibas
customers to our new Neuron 5000 processor, which we purchase from Open-Silicon. Another semiconductor supplier, STMicroelectronics, manufactures our power line smart transceiver products, for which we have no alternative source. In addition, we
currently purchase several key products and components from sole or limited source suppliers with which we do not maintain signed agreements that would obligate them to supply to us on negotiated terms.

We are continuing to review the impact that the ongoing worldwide financial crisis is having on our suppliers. Some of these suppliers
are large, well capitalized companies, while others are smaller and more highly leveraged. In order to mitigate these risks, we may take actions such as increasing our inventory levels and/or adding additional sources of supply. Such actions may
increase our costs and increase the risk of excess and obsolete inventories. Even if we undertake such actions, there can be no assurance that we will be able to prevent any disruption in the supply of goods and services we receive from these
suppliers.

We may also elect to change any of these key suppliers. For example, in 2009 we completed the process of ending
our relationship with a former CEM partner, Flextronics. As part of this transition, we moved the production of products Flextronics built for us to alternative CEMs. We were also required to purchase certain raw material and in-process inventory
from Flextronics that Flextronics procured in anticipation of our production requirements. In addition, if any of our key suppliers were to stop manufacturing our products or supplying us with our key components, it could be expensive and time
consuming to find a replacement. Also, as our NES business grows, we will be required to expand our business with our key suppliers or find additional sources of supply. There is no guarantee that we would be able to find acceptable alternative or
additional sources. Additional risks that we face if we must transition between CEMs include:



| |  |  | moving raw material, in-process inventory, and capital equipment between locations, some of which may be in different parts of the world;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reestablishing acceptable manufacturing processes with a new work force; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | exposure to excess or obsolete inventory held by contract manufacturers for use in our products.
| | - |  | ------------------------------------------------------------------------------------------------

The failure of any key manufacturer to produce a sufficient number of products on time, at agreed quality levels, and fully compliant
with our product, assembly and test specifications could result in our failure to ship products, which would adversely affect our revenues and gross profit, and could result in claims against us by our customers, which could harm our results of
operations and financial position.

Liabilities resulting from defects
in or misuse of our products, whether or not covered by insurance, may delay our revenues and increase our liabilities and expenses.

Our products may contain or may be alleged to contain undetected errors or failures. In addition, our customers or their installation partners may improperly install or implement our products, which could
delay completion of a deployment or hinder our ability to win a subsequent award. Furthermore, 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.

Even if we determine that an alleged error or failure in our products does not exist, we may incur expense
and shipments and revenue may be delayed while we analyze the alleged error or failure. If errors or failures are found in our products, we may not be able to successfully correct them in a timely manner, or at all. Such errors or failures could
delay our product shipments and divert our engineering resources while we attempt to correct them. In addition, we could decide to extend the warranty period, or incur other costs outside of our normal warranty coverage, to help address any known
errors or failures in our products and mitigate the impact on our customers. This could delay our revenues and increase our expenses.

To address these issues, the agreements we maintain with our customers may contain provisions intended to limit our exposure to potential errors and omissions claims as well as any liabilities arising
from them. However, our customer contracts may not effectively protect us against the liabilities and expenses associated with errors or failures attributable to our products.

Defects in our products may also cause us to be liable for losses in the event of property damage, harm or death to persons, claims against our directors or officers, and the like. Such liabilities could
harm our reputation, expose our company to liability, and adversely affect our operating results and financial position.

To
help reduce our exposure to these types of liabilities, we currently maintain property, general commercial liability, errors and omissions, directors and officers, and other lines of insurance. However, it is possible that such insurance may not be
available in the future or, if available, may be insufficient in amount to cover any particular claim, or we might not carry insurance that covers a specific claim. In addition, we believe that the premiums for the types of insurance we carry will
continue to fluctuate from period to period. Significant cost increases could also result in increased premiums or reduced coverage limits. Consequently, if we elect to reduce our coverage, or if we do not carry insurance for a particular type of
claim, we will face increased exposure to these types of claims.

Because the markets for our products are highly competitive, we may lose
sales to our competitors, which would harm our revenues and results of operations.

Competition in our markets is intense
and involves rapidly changing technologies, evolving industry standards, frequent new product introductions, rapid changes in customer or regulatory requirements, and localized market requirements. In each of our markets, we compete with a wide
array of manufacturers, vendors, strategic alliances, systems developers and other businesses.

The principal competitive
factors that affect the markets for our products include the following:



| |  |  | our ability to anticipate changes in customer or regulatory requirements and to develop or improve our products to meet these requirements in a timely
manner;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the price and features of our products such as adaptability, scalability, functionality, ease of use, and the ability to integrate with other products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our product reputation, quality, performance, and conformance with established industry standards;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | our ability to expand our product line to address our customers requirements, such as adding additional electricity meter form factors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to meet a customers required delivery schedules;
| | - |  | -------------------------------------------------------------



| |  |  | our customer service and support;
| | - |  | ---------------------------------



| |  |  | warranties, indemnities, and other contractual terms; and
| | - |  | ---------------------------------------------------------



| |  |  | customer relationships and market awareness.
| | - |  | --------------------------------------------

Competitors for our
NES System products include Aclara, Elster, Enel, GE, IBM, Iskraemeco, Itron, the Landis+Gyr group of companies, Siemens, and Silver Spring Networks, which directly or through IT integrators such as IBM or telecommunications companies such as
Telenor, offer metering systems that compete with our NES System offering.

For our LWI products, our competitors include some
of the largest companies in the electronics industry, operating either alone or together with trade associations and partners. Key company competitors include companies such as Siemens and Tridium in the building industry; Allen-Bradley (a
subsidiary of Rockwell Automation), Groupe Schneider and Siemens in the industrial automation industry; Siemens in the transportation industry; and Zensys in the home control market. Key industry standard and trade group competitors include BACnet,
DALI, and Konnex in the buildings industry; DeviceNet, HART, and Profibus in the industrial control market; DLMS in the utility industry; Echonet, ZigBee and the Z-Wave alliance in the home control market; and the Train Control Network (TCN) in the
rail transportation market. Each of these standards and/or alliances is backed by one or more competitors. For example, the ZigBee alliance includes over 300 member companies with promoter members such as Ember, Emerson, Freescale, Itron, Kroger,
Landis+Gyr, Philips, Reliant Energy, Schneider Electric, STMicroelectronics, Tendril, and Texas Instruments.

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. In addition,
the utility metering market is experiencing a trend towards consolidation. 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. Some of our competitors may also be eligible for stimulus money, which could give them an additional financial advantage. If we are unable to compete effectively in any of the markets we serve,
our revenues, results of operations, and financial position would be harmed.

Because our products use components or materials that may be
subject to price fluctuations, shortages, interruptions of supply, or discontinuation, we may be unable to ship our products in a timely fashion, which would adversely affect our revenues, harm our reputation and negatively impact our results of
operations.

We may be vulnerable to price increases for products, components, or materials, such as copper and cobalt. We
generally do not enter into forward contracts or other methods of hedging against supply risk for these items. In addition, in the past we have occasionally experienced shortages or interruptions in supply for certain of these items, including
products or components that have been or will be discontinued, which caused us to delay shipments beyond targeted or announced dates. To help address these issues, we may decide to purchase quantities of these items that are in excess of our
estimated requirements. As a result, we could be forced to increase our excess and obsolete inventory reserves to provide for these excess quantities, which could harm our operating results. In addition, if a component or other product goes out of
production, we may be required to requalify substitute components or products, or even redesign our products to incorporate an alternative component or product.

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 them from alternate
sources at acceptable prices and within a reasonable period of time, our revenues, gross profits or both could decrease. In addition, under the terms of some of our contracts with our customers, we may also be subject to penalties if we fail to
deliver our products on time.

Voluntary standards and governmental regulatory actions in our markets could limit our ability to sell our
products.

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. We participate in many voluntary standards organizations around the world in order to both help prevent the 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 and our efforts to influence the direction of those standards bodies in which we do participate may not be
successful. Many of our competitors have significantly more resources focused on standards activities and may influence those standards in a way that would be disadvantageous to our products.



41

Many of our products
and the industries in which they are used are subject to U.S. and foreign regulation. 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. In general, these regulations limit the ability of companies 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 our products or to
increase the market opportunity for their own products.

In addition, the market for our NES and LWI products may experience a
movement towards standards based protocols driven by governmental action, such as those being considered in the U.S. by NIST and in Europe by those related to the EU 441 mandate. We are also attempting to gain adoption for our Open Smart Grid
Protocol, which is used by smart meters and other devices within our NES System. To the extent that we do not adopt such protocols or do not succeed in achieving adoption of our own protocols as standards or de facto standards, sales of our NES and
LWI products may be adversely affected. Moreover, if our own protocols are adopted as standards, we run the risk that we could lose business to competing implementations.

The adoption of voluntary standards or the passage of governmental regulations that are incompatible with our products or technology could limit the market opportunity for our products, which could harm
our revenues, results of operations, and financial condition.

Our executive officers and technical personnel are critical to our business.

Our success depends substantially on the performance of our executive officers and key employees. Due to the specialized
technical nature of our business, we are particularly dependent on our Chief Executive Officer and our technical personnel. In November 2009, we announced that our Chairman and CEO would step down as CEO for health reasons. At the same time, we
announced that one of our existing directors would become our CEO on an interim basis, while we conducted a search for a new CEO. Our search was completed and our new CEO joined Echelon in August 2010. Our future success will depend on our ability
to attract, integrate, motivate and retain qualified managerial, technical, sales, and operations personnel.

Competition for
qualified personnel in our business areas is intense, and we may not be able to continue to retain a qualified CEO or other executive officers and key personnel and attract new officers and personnel when necessary. Our product development and
marketing functions are largely based in Silicon Valley, which is a highly competitive marketplace. It may be particularly difficult to recruit, relocate and retain qualified personnel in this geographic area. Moreover, the cost of living, including
the cost of housing, in Silicon Valley is known to be high. Because we are legally prohibited from making loans to executive officers, we will not be able to assist potential key personnel as they acquire housing or incur other costs that might be
associated with joining our company. In addition, if we lose the services of any of our key personnel and are not able to find suitable 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 their replacements.

Due to the financial and operational risks
associated with our international operations, our revenues may decline due to risks unrelated to our ability to sell our products.

We have operations located in eleven countries and our products are sold in many more countries around the world. Revenues from international sales, which include both export sales and sales by
international subsidiaries, accounted for about 80.2% of our total net revenues for the quarter ended September 30, 2010, and 82.0% of our total net revenues for the same period in 2009, and 76.4% of our total net revenues for the nine months
ended September 30, 2010 and 80.0% for the same period in 2009. We expect that international sales will continue to constitute a significant portion of our total net revenues.

Changes in the value of currencies in which we conduct our business relative to the U.S. dollar have caused and could continue to cause
fluctuations in our reported financial results. The three primary areas where we are exposed to foreign currency fluctuations are revenues, cost of goods sold, and operating expenses.

In general, we sell our products to foreign customers primarily in U.S. dollars. As such, fluctuations in exchange rates have had in the
past and could continue to have an impact on revenues. As the value of the dollar rises, our products will become more expensive to our foreign customers, which could result in their decision to postpone or cancel a planned purchase.



42



---



With respect to the
relatively minimal amount of our revenues generated in foreign currencies, our historical foreign currency exposure has been related primarily to the Japanese Yen and has not been material to our consolidated results of operations. However, in the
future, we expect that some foreign utilities may require us to price our NES System in the utilitys local currency, which will increase our exposure to foreign currency risk. In addition, we have agreed with EBV, our European distributor,
that upon notice from EBV, we will sell our products to EBV in European Euros rather than U.S. dollars. If EBV were to exercise this right, our revenue exposure to foreign currency fluctuations would increase.

For our cost of goods sold, our products are generally assembled by CEMs in China. Although our transactions with these vendors have
historically been denominated in U.S. dollars, in the future they may require us to pay in their local currency, or demand a U.S. dollar price adjustment or other payment to address a change in exchange rates, which would increase our cost to
procure our products. This is particularly a risk in China, where any future revaluations of the Chinese currency against the U.S. dollar could result in significant cost increases. In addition, any future increase in labor costs in the markets
where our products are manufactured could also result in higher costs to procure our products.

We use the local currency to
pay for our operating expenses in the various countries where we have operations. If the value of the U.S. dollar declines as compared to the local currency where the expenses are incurred, our expenses, when translated back into U.S. dollars, will
increase.

To date, we have not hedged any of our foreign currency exposures and currently do not maintain any hedges to
mitigate our foreign currency risks. Consequently, any resulting adverse foreign currency fluctuations could significantly harm our revenues, cost of goods sold, or operating expenses.

Additional risks inherent in our international business activities include the following:



| |  |  | the imposition of tariffs or other trade barriers on the importation of our products;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | timing of and costs associated with localizing products for foreign countries and lack of acceptance of non-local products in foreign countries;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | inherent challenges in managing international operations;
| | - |  | ---------------------------------------------------------



| |  |  | the burdens of complying with a wide variety of foreign laws; the applicability of foreign laws that could affect our business or revenues, such as
laws that purport to require that we return payments that we received from insolvent customers in certain circumstances; and unexpected changes in regulatory requirements, tariffs, and other trade barriers;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potentially adverse tax consequences, including restrictions on repatriation of earnings;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | economic and political conditions in the countries where we do business;
| | - |  | ------------------------------------------------------------------------



| |  |  | differing vacation and holiday patterns in other countries, particularly in Europe;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | labor actions generally affecting individual countries, regions, or any of our customers, which could result in reduced demand for, or could delay
delivery or acceptance of, our products; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | international terrorism.
| | - |  | ------------------------

Any of these factors could have a material adverse effect on our revenues, results of operations, and our financial condition.

We may be unable to promote and
expand acceptance of our open, interoperable control systems over competing protocols, standards, or technologies.

LONWORKS technology is open, meaning that many of our technology patents are broadly licensed without
royalties or license fees. As a result, our LWI customers are able to develop hardware and software solutions that compete with some of our products. Because some of our customers are OEMs that develop and market their own control systems, these
customers in particular could develop competing products based on our open technology. For instance, we have published all of the network management commands required to develop software that competes with our LNS software.

In addition, many of our LWI 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. We also face strong competition from large trade associations that promote alternative technologies and standards for particular vertical applications or for use in
specific countries. These include BACnet, DALI, and KNX in the buildings market; DeviceNet, HART, and ProfiBus in the industrial controls market; TCN in the rail transportation market; DLMS in the electric metering market; and Echonet, ZigBee, and
Z-Wave in the home control market.

Our technologies, protocols, or standards may not be successful or we may not be able to
compete with new or enhanced products or standards introduced by our LWI product line competitors, which would have a material adverse affect on our revenues, results of operations, and financial condition.

If we are not able to develop or enhance our products in a timely manner, our revenues will suffer.

Due to the nature of development efforts in general, we often experience delays in the introduction of new or improved products beyond our
original projected shipping date for such products. Historically, when these delays have occurred, we experienced an increase in our development costs and a delay in our ability to generate revenues from these new products. In addition, such delays
could impair our relationship with any of our customers that were relying on the timely delivery of our products in order to complete their own products or projects. We believe that similar new product introduction delays in the future could also
increase our costs and delay our revenues.

If we do not maintain adequate distribution channels, our revenues will be harmed.

We market our NES System products directly, as well as through selected VARs and integration partners. We believe that a
significant portion of our NES System sales will be made through our VARs and integration partners, rather than directly by us. To date, our VARs and integration partners have greater experience in overseeing projects for utilities. As a result, if
our relationships with our VARs and integration partners are not successful, or if we are not able to create similar distribution channels for our NES System products with other companies in other geographic areas, revenues from sales of our NES
System products may not meet our financial targets, which will harm our operating results and financial condition.

Currently,
significant portions of our LWI revenues are derived from sales to distributors, including EBV, the primary independent distributor of our products to OEMs in Europe. Historically, sales to EBV, as well as sales to our other distributor partners,
have accounted for a substantial portion of our total LWI revenues. Agreements with our distributor partners are generally renewed on an annual basis. If any of these agreements are not renewed, we would be required to locate another distributor or
add our own distribution capability to meet the needs of our end-use customers. Any replacement distribution channel could prove less effective than our current arrangements. In addition, if any of our distributor partners fail to dedicate
sufficient resources to market and sell our products, our revenues would suffer. Furthermore, if they significantly reduce their inventory levels for our products, service levels to our end-use customers could decrease.

Because we may incur penalties and/or be liable for damages with respect to sales of our NES System products, we could incur unanticipated liabilities
that would negatively affect our operating results.

In the event of late deliveries, late or improper installations or
operations, failure to meet product specifications or other product failures, failure to achieve performance specifications, indemnities or other compliance issues, the agreements governing the sales of the NES System may expose us to penalties,
damages and other liabilities. Even in the absence of such contractual provisions, we may agree, or may be required by law, to assume certain liabilities for the benefit of our customers. Any such liabilities would have an adverse effect on our
financial condition and operating results.

If we sell our NES System products
directly to a utility, we will face additional risks.

When we sell our NES System products to a utility directly, we may
be required to assume responsibility for installing the NES System in the utilitys territory, integrating the NES System into the utilitys operating and billing system, overseeing management of the combined system, working with other of
the utilitys contractors, and undertaking other activities. To date, we do not have any significant experience with providing these types of services. As a result, when we sell directly to a utility, it may be necessary for us to contract
with third parties to satisfy these obligations. We cannot assure you that we would find appropriate third parties to provide these services on reasonable terms, or at all. Assuming responsibility for these or other services would add to the
costs and risks associated with NES System installations, and could also negatively affect the timing of our revenues and cash flows related to these transactions.

The sales cycle for our LWI products is lengthy and unpredictable.

The
sales cycle between initial LWI customer contact and execution of a contract or license agreement with a customer or purchaser of our products, can vary widely. Initially, we must educate our customers about the potential applications of and cost
savings associated with our products. If we are successful in this effort, OEMs typically conduct extensive and lengthy product evaluations before making a decision to design our products into their offerings. Once the OEM decides to incorporate our
products, volume purchases of our products are generally delayed until the OEMs product development, system integration, and product introduction periods have been completed. In addition, changes in our customers budgets, or the priority
they assign to control network development, could also affect the sales cycle.

We generally have little or no control over
these factors, any of which could prevent or substantially delay our ability to complete a transaction and could adversely affect the timing of our revenues and results of operations.

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

Our quarterly and annual results have varied significantly from period to period, and we have sometimes failed to meet securities
analysts expectations. Moreover, we have a history of losses and cannot assure you that we will achieve sustained profitability in the future. Our future operating results will depend on many factors, many of which are outside of our control,
including the following:



| |  |  | the mix of products and services that we sell may change to a less profitable mix;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | shipment, payment schedules, and product acceptance may be delayed;
| | - |  | -------------------------------------------------------------------



| |  |  | our products may not be purchased by utilities, OEMs, systems integrators, service providers and end-users at the levels we project;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may be required to modify or add to our NES product offerings to meet a utilitys requirements, which could delay delivery and/or acceptance of
our products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the complex revenue recognition rules relating to products such as our NES System could require us to defer some or all of the revenue associated with
NES product shipments until certain conditions, such as delivery and acceptance criteria for our software and/or hardware products, are met in a future period;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our contract electronic manufacturers may not be able to provide quality products on a timely basis, especially during periods where capacity in the
CEM market is limited;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our products may not be manufactured in accordance with specifications or our established quality standards, or may not perform as designed;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



45



---



| |  |  | downturns in any customers or potential customers business, or declines in general economic conditions, could cause significant reductions
in capital spending, thereby reducing the levels of orders from our customers;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | recording of expense relating to equity compensation will decrease our earnings;
| | - |  | --------------------------------------------------------------------------------



| |  |  | we may incur costs associated with any future business acquisitions; and
| | - |  | ------------------------------------------------------------------------



| |  |  | any future impairment charges related to goodwill, other intangible assets, and other long-lived assets required under generally accepted accounting
principles in the United States may negatively affect our earnings and financial condition.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Any of the
above factors could, individually or in the aggregate, have a material adverse effect on our results of operations and our financial condition, which could cause our stock price to decline.

Our business may suffer if it is alleged or found that our products infringe the intellectual property rights of others.

We may be contractually obligated to indemnify our customers or other third parties that use our products in the event our products are
alleged to infringe a third partys intellectual property rights. From time to time, we may also receive notice that a third party believes that our products may be infringing patents or other intellectual property rights of that third party.
Responding to those claims, regardless of their merit, can be time consuming, result in costly litigation, divert managements attention and resources, and cause us to incur significant expenses. We do not insure against infringement of a third
partys intellectual property rights.

As the result of such a claim, we may elect or be required to redesign our
products, some of our product offerings could be delayed, or we could be required to cease distributing some of our products. In the alternative, we could seek a license to the third partys intellectual property. Even if our products do not
infringe, we may elect to take a license or settle to avoid incurring litigation costs. However, it is possible that we would not be able to obtain such a license or settle on reasonable terms, or at all.

Lastly, our customers may not purchase our products if they are concerned our products may infringe third party intellectual property
rights. This could reduce the market opportunity for the sale of our products and services.

Any of the foregoing risks could
have a material adverse affect on our revenues, results of operations, and financial condition.

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 these intellectual property rights, all of which afford only limited protection. If any
of our patents fail to protect our technology, or if we do not obtain patents in certain countries, our competitors may find it easier to offer equivalent or superior technology.

We have also registered or applied for registration for certain trademarks, and will continue to evaluate the registration of additional
trademarks as 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 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 use information that we regard as proprietary, or it may not be economically feasible to enforce them. Any of our patents,
trademarks, copyrights or intellectual property rights could be challenged, invalidated or circumvented. In addition, we cannot assure you 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. 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 and it may take longer to receive a remedy from a court outside of the United States. Also, some 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.



46



---



From time to time,
litigation may be necessary to defend and enforce our proprietary rights. As a result, 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 third parties from infringing,
misusing, misappropriating, or independently developing our technology or intellectual property rights, or to prevent an unauthorized third party from misappropriating our products or technology.

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 the following:



| |  |  | significant stockholders may sell some or all of their holdings of our stock;
| | - |  | -----------------------------------------------------------------------------



| |  |  | investors may be concerned about our ability to develop additional customers for our products and services; and
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | volatility in our stock price may be unrelated or disproportionate to our operating performance.
| | - |  | ------------------------------------------------------------------------------------------------

Any of these factors could have a negative impact on the market price of our stock.

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

As of October 31, 2010, our directors and executive officers, together with certain entities affiliated with
them (including, for this purpose, Enel, which has the right to nominate a director to our board of directors), beneficially owned 29.8% of our outstanding stock.

When we sold 3.0 million newly issued shares of our common stock to Enel on September 11, 2000, we granted Enel the right to nominate a director to our board of directors, although a nominee of
Enel does not currently sit on our board. In connection with the stock sale, our directors and our Chief Financial Officer agreed to enter into a voting agreement with Enel in which each of them agreed to vote in favor of Enels nominee to our
board of directors. In addition, Enel agreed to vote for our boards recommendations for the election of directors, approval of accountants, approval of Echelons equity compensation plans, and certain other matters. 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.

We are subject to numerous governmental regulations concerning the manufacturing and use of our products. We must stay
in compliance with all such regulations and any future regulations. Any failure to comply with such regulations, and the unanticipated costs of complying with future regulations, may adversely affect our business, financial condition, and results of
operations.

We manufacture and sell products that contain electronic components that may contain materials that are
subject to government regulation in the locations in which our products are manufactured and assembled, as well as the locations where we sell our products. Since we operate on a global basis, maintaining compliance with regulations concerning the
materials used in our products is a complex process that requires continual monitoring of regulations and ongoing compliance procedures. While we do not currently know of any proposed regulations regarding components in our products that would have
a material impact on our business, the adoption of any unanticipated new regulations that significantly impact the various components we use or require that we use more expensive components would have a material adverse impact on our business,
financial condition and results of operations.



47



---



Our manufacturing
processes, including the processes used by our suppliers, are also subject to numerous governmental regulations that cover both the use of various materials as well as environmental concerns. Since we and our suppliers operate on a global basis,
maintaining compliance with regulations concerning our production processes is also a complex process that requires continual monitoring of regulations and ongoing compliance procedures. For example, environmental issues such as pollution and
climate change have seen significant legislative and regulatory interest on a global basis. Changes in these areas could directly increase the cost of energy, which may have an impact on the way we or our suppliers manufacture products or use energy
to produce our products. In addition, any new regulations or laws in the environmental area might increase the cost of raw materials we use in our products. We are currently unable to predict how any such changes will impact us and if any such
impact could be material to our business. Any new law or regulation that significantly increases our costs of manufacturing or causes us or our suppliers to significantly alter the way that our products are manufactured would have a material adverse
affect on our business, financial condition and results of operations.

Natural disasters, power outages, and other factors outside of our
control such as widespread pandemics could disrupt our business.

We must protect our business and our network
infrastructure against damage from earthquake, flood, hurricane and similar events, as well as from power outages. A natural disaster, power outage, or other unanticipated problem could also adversely affect our business by, among other things,
harming our primary data center or other internal operations, limiting our ability to communicate with our customers, and limiting our ability to sell our products. We do not insure against several natural disasters, including earthquakes.

Any outbreak of a widespread communicable disease pandemic, such as the outbreak of the H1N1 influenza virus in 2009 or the
SARS epidemic of 2003, could similarly impact our operations. Such impact could include, among other things, the inability for our sales and operations personnel located in affected regions to travel and conduct business freely, the impact any such
disease may have on one or more of the distributors for our products in those regions, and increased supply chain costs. Additionally, any future health-related disruptions at our third-party contract manufacturers or other key suppliers could
affect our ability to supply our customers with products in a timely manner, which would harm our results of operations.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
|------- | -----------------------------------------------------------

We have not experienced any material change in our exposure to interest rate and foreign currency risks since the date of our Annual Report on Form 10-K for the year ended December 31, 2009.

Market Risk Disclosures. The following discussion about our market risk disclosures involves
forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use
derivative financial instruments to hedge these exposures.

Interest Rate Sensitivity. We maintain a short-term
investment portfolio consisting mainly of fixed income securities with a weighted average maturity of less than one year. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase.
If market rates were to increase immediately and uniformly by 10% from levels at September 30, 2010 and December 31, 2009, the fair value of the portfolio would decline by an immaterial amount. We currently intend to hold our fixed income
investments until maturity, and therefore we would not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates. However, if necessary, we may sell short-term investments prior
to maturity to meet the liquidity needs of the company.

Foreign Currency Exchange Risk. We have international
subsidiaries and operations and are, therefore, subject to foreign currency rate exposure. To date, our exposure to exchange rate volatility has not been significant. If foreign exchange rates were to fluctuate by 10% from rates at
September 30, 2010, and December 31, 2009, our financial position and results of operations would not be materially affected. However, we could experience a material impact in the future.

In addition, for our
cost of goods sold, our products are generally assembled by CEMs in China, although our transactions with these vendors have historically been denominated in U.S. dollars. These vendors may require us to pay in their local currency, or demand a U.S.
dollar price adjustment or other payment to address a change in exchange rates, which would increase our cost to procure our products. This is particularly a risk in China, where any future revaluations of the Chinese currency against the U.S.
dollar could result in significant cost increases.



|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of Effectiveness of Disclosure Controls and Procedures

We have designed our disclosure controls and procedures to ensure that information we are required to disclose in reports that we file or
submit under the Securities and Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure, and
that such information is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. As of the end of the period covered by this Quarterly Report on Form 10-Q, under the supervision of our Chief
Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures, as such terms are defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities and Exchange Act of 1934.
Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of September 30, 2010.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(e) of the Exchange Act) that occurred
during the quarter ended September 30, 2010, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

In April 2008, our board of directors approved a new stock repurchase program, which authorizes us to repurchase up to 3.0 million shares of our common stock, in accordance with Rule 10b-18 and other
applicable laws, rules and regulations. There were no repurchases under the new stock repurchase program during the quarter and nine months ended September 30, 2010. Since inception, we have repurchased a total of 750,000 shares under the
program at a cost of $8.9 million. As of September 30, 2010, 2,250,000 shares were available for repurchase. This stock repurchase program will expire in April 2011.
