EXPLANATORY NOTE

In this Quarterly Report on Form 10-Q/A we are restating our condensed consolidated balance sheets as of June 30, 2007 and December 31, 2006, and our related condensed consolidated statements of operations
and cash flows for the three- and six-month periods ended June 30, 2007 and 2006. As reported on April 22, 2008, during the preparation of our financial results for the quarter ended March 31, 2008, we identified an error in our
previously reported equity compensation expense. On April 30, 2008, we reported that we had also inappropriately accounted for the 1999 and 2001 leases of our San Jose, California corporate headquarters facilities.

The effects of all restatement adjustments on our condensed consolidated balance sheets as of June 30, 2007 and December 31, 2007 and 2006 are
as follows:

Included in Note 2 of Notes to Condensed Consolidated Financial Statements in this Report are
tables that present the effects of all restatement adjustments on the condensed consolidated financial statements reconciling the previously reported data to the as restated data for the Condensed Consolidated Balance Sheets as of
June 30, 2007 and December 31, 2006, and the Condensed Consolidated Statements of Operations and Cash Flows for the three- and six-month periods ended June 30, 2007 and 2006. The restatements are further discussed below.

Restatement of stock-based compensation expense:During the preparation of our financial results for the quarter ended March 31,
2008, we identified an error in our previously reported stock-based compensation expense for the years ended December 31, 2007, 2006 and 2005, and each of the quarterly periods in 2007 and 2006. The error was isolated to share awards and does
not affect the other forms of our equity compensation awards, namely stock options and stock-settled stock appreciation rights. While the grant date fair value of the share awards was determined correctly in accordance with Statement of Financial
Accounting Standard (SFAS) No. 123R (revised 2004), Share-Based Payment, the amount of expense associated with these awards that was recognized in 2007, 2006 and 2005 was not correct. The error was caused by a misapplication
of the widely-used equity compensation software application we use to manage and account for our equity compensation awards. This misapplication caused the expense associated with these share awards to be calculated using the straight-line,
single-option method rather than the accelerated, multiple-option method, which we had elected to use for all of our equity compensation awards. Use of the straight-line, single-option method resulted in understatements of stock-based compensation
expense in 2007, 2006 and 2005 of $1.2 million, $535,000 and $263,000, respectively. For the three months ended June 30, 2007 and 2006, stock-based compensation expense was understated by $188,000 and $164,000, respectively. For the six
months ended June 30, 2007 and 2006, stock-based compensation expense was understated by $341,000 and $309,000, respectively.

Restatement related to the leases of our San Jose, California headquarters facilities: In connection with the restatement of stock-based compensation expense, KPMG LLP, our independent registered public accounting firm,
brought to our attention that we had inappropriately accounted for the leases of our corporate headquarters facilities that were entered into in 1999 and 2001. Under the guidance in Emerging Issues Task Force Issue No. 97-10,The Effect of
Lessee Involvement in Asset Construction (EITF 97-10), and SFAS No. 98,Accounting for Leases:

##### Table of Contents

Sale-Leaseback transactions Involving Real Estate; Sales-Type Leases of Real Estate; Definition of the Lease Term; Initial Direct Costs of Direct
Financing Leases; an amendment of FASB Statements No. 13, 66, and 91 and a rescission of FASB Statement No. 26 and Technical Bulletin No. 79-11(SFAS 98), we should have reflected an asset on our balance sheet for the
costs paid by the lessor to construct our headquarters facilities, as well as a corresponding liability, because we were the deemed owner of the headquarters facilities for accounting purposes during the construction periods. Upon
completion of construction, we did not meet the sale-leaseback criteria under SFAS 98 and therefore should have treated the leases as financing obligations and the assets and corresponding liabilities would not be derecognized. We had
historically accounted for these leases as operating leases under SFAS No. 13,Accounting for Leases(SFAS 13), whereby the total minimum lease payment obligations under the leases were recognized as monthly rent expense on a
straight-line basis over the terms of the leases.The restatement adjustments do not affect the total cash payments we have made or are obligated to make under the lease agreements, nor do they change the total expense to be recognized over
the lease terms. However, the timing and nature of expenses in the statement of operations is different under this treatment as compared to operating lease treatment. Specifically, we should have recognized land lease expense, depreciation expense
on the assets we are deemed to own and interest expense on the associated lease financing obligations. For a more detailed description of the effects on our condensed consolidated financial statements, see Note 2 of Notes to Condensed Consolidated
Financial Statements included in Part I, Item 1 of this Report.

Our management and the Audit Committee of our Board of
Directors have concluded that these errors in our Condensed Consolidated Financial Statements were unintentional, and no misdeed or fraud was involved in any respect. The Audit Committee also determined that the error in stock-based compensation
expense was in no way caused by any backdating of or similar improper activity involving stock option grants. In conjunction with the Audit Committee, we have determined that the errors are a result of material weaknesses in our internal control
over financial reporting, as such term is defined by Securities and Exchange Commission Rule 1-02(a)(4) of Regulation S-X. See further explanation of the material weaknesses and remediation plans in Part I, Item 4 Controls and
Procedures (as restated) of this Report.

Except for the matters related to the aforementioned restatements and material weaknesses,
this Amendment No. 1 does not modify or update other disclosures in the originally filed Form 10-Q.

The Company will also file
amendments to its 2007 Form 10-K and Forms 10-Q for each of the quarters ended March 31 and September 30, 2007. The amended 2007 filings will include restated information for periods affected by these restatements.

This Form 10-Q/A also reflects the restatement of related information contained in (i) Managements Discussion and Analysis of Financial
Condition and Results of Operations in Part I, Item 2.

ECHELON CORPORATION

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 included in this
report reflect all adjustments (consisting only of normal recurring adjustments) which the Company considers necessary for the fair presentation of the results of operations for the interim periods covered and of the financial condition of the
Company at the date of the interim balance sheet. The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the
Companys consolidated financial statements for the year ended December 31, 2007 included in its Annual Report on Form 10-K/A filed concurrently with this Quarterly Report on Form 10-Q/A.

Revenue Recognition

The Companys revenues are
derived from the sale and license of its products and to a lesser extent, from fees associated with training, technical support, and custom software design services offered to its 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.

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable,
collectibility is probable, and there are no post-delivery obligations. For hardware sales, including sales to third party manufacturers, these criteria are generally met at the time of shipment. For sales made to the Companys distributor
partners, these criteria are generally met at the time the distributor sells the products through to its end-use customer. For software licenses, these criteria are generally met upon shipment to the final end-user. Service revenue is recognized as
the training services are performed, or ratably over the term of the support period. In the case of custom software development services, revenue is recognized when the customer accepts the software.

In accordance with AICPA Statement of Position 97-2 (SOP 97-2), Software Revenue Recognition, as amended, revenue earned on software
arrangements involving multiple elements is allocated to each element based upon the relative fair values of the elements. The Company uses the residual method to recognize revenue when a license agreement includes one or more elements to be
delivered at a future date. In these instances, the amount of revenue deferred at the time of sale is based on vendor specific objective evidence (VSOE) of the fair value for each undelivered element. If VSOE of fair value does not exist
for each undelivered element, all revenue attributable to the multi-element arrangement is deferred until sufficient VSOE of fair value exists for each undelivered element or all elements have been delivered.

The Company currently sells a limited number of its LONWORKS® Infrastructure products that are considered multiple element arrangements under SOP 97-2. Revenue for the software license element is recognized at the time of delivery of the
applicable product to the end-user. The only undelivered element at the time of sale consists of post-contract customer support (PCS). The VSOE for this PCS is based on prices paid by the Companys customers for stand-alone
purchases of PCS. Revenue for the PCS element is deferred and recognized ratably over the PCS service period. The costs of providing these PCS services are expensed when incurred.

In certain instances, the Companys Networked Energy Services (NES) System products are sold as part of multiple element arrangements,
which may include electricity meters and data concentrators (collectively, the Hardware); NES System software, for which a royalty is charged on a per-meter basis; PCS for the NES System software; and extended warranties for the
Hardware. These arrangements may require the Company to deliver Hardware over an extended period of time. In accordance with SOP 97-2, when the multiple element arrangement includes NES System 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 NES System
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. The Company has
established VSOE for the PCS on the NES System software, as well as for the warranties on its NES Hardware products. These revenues are recognized ratably over the associated service period, which generally commences upon the latter of the delivery
of all software, or the customers acceptance of any given Hardware shipment.

The Company accounts for the rights of return, price
protection, rebates, and other sales incentives offered to its distributors in accordance with Statement of Financial Accounting Standards (SFAS) No. 48, Revenue Recognition When Right of Return Exists,and Emerging Issues
Task Force (EITF) Issue No. 01-09,Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendors Products). During the first and second quarters of 2006, the Company modified its
revenue recognition method for sales made to its distributor partners. Under the revised method, revenue on sales made to distributors is deferred until the distributor sells the products through to its end-use customers. The impact of these revenue
recognition methodology revisions were one-time reductions in revenues of approximately $1.0 million during the quarter ended June 30, 2006, and $3.9 million during the six month period ended June 30, 2006.

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.

Recent Accounting Pronouncements

With the exception of the Financial Accounting Standards Board ( FASB) statement described below, there have been no significant changes in
recent accounting pronouncements during the three and six months ended June 30, 2007, as compared to the recent accounting pronouncements described in our Annual Report on Form 10-K for the year ended December 31, 2006.

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (SFAS 159), The Fair Value Option for Financial
Assets and Financial Liabilities. SFAS 159 permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value
option has been elected be reported in earnings. SFAS 159 is effective for the Company beginning in its fiscal year ending December 31, 2008, although earlier adoption is permitted. The Company is currently evaluating the impact that SFAS 159
will have on its consolidated financial statements.

2. Restatement of Condensed Consolidated Financial Statements:

During the preparation of its financial results for the quarter ended March 31, 2008, the Company identified an error in its previously reported
equity compensation expense and determined it had inappropriately accounted for the 1999 and 2001 leases of its San Jose, California corporate headquarters facilities.

Restatement of stock-based compensation expense:The Company identified an error in its previously reported stock-based compensation expense for the years ended December 31, 2007, 2006 and 2005 and
each of the quarterly periods in 2007 and 2006. The error was isolated to share awards and does not affect the other forms of our equity compensation awards, namely stock options and stock-settled stock appreciation rights. While the grant date fair
value of the share awards was determined correctly in accordance with SFAS No. 123R (revised 2004), Share-Based Payment (SFAS 123R), the amount of expense associated with these awards that was recognized in 2007, 2006
and 2005 was not correct. The error was caused by a misapplication of the widely-used equity compensation software application the Company uses to manage and account for its equity compensation awards. This misapplication caused the expense
associated with these share awards to be calculated using the straight-line, single-option method rather than the accelerated, multiple-option method, which the Company had elected to use for all of its equity compensation awards. Use of the
straight-line, single-option method resulted in understatements of stock-based

##### Table of Contents

compensation expense in 2007, 2006 and 2005 of $1.2 million, $535,000 and $263,000, respectively. For the three-month periods ended June 30, 2007
and 2006, stock-based compensation expense was understated by $188,000 and $164,000, respectively. For the six-month periods ended June 30, 2007 and 2006, stock-based compensation expense was understated by $341,000 and $309,000, respectively.

Restatement related to the leases of our San Jose, California headquarters facilities: The Company inappropriately accounted
for the leases of its corporate headquarters facilities that were entered into in 1999 and 2001. Under the guidance in Emerging Issues Task Force Issue No. 97-10,The Effect of Lessee Involvement in Asset Construction (EITF
97-10), and SFAS No. 98,Accounting for Leases: Sale-Leaseback transactions Involving Real Estate; Sales-Type Leases of Real Estate; Definition of the Lease Term; Initial Direct Costs of Direct Financing Leases; an amendment of FASB
Statements No. 13, 66, and 91 and a rescission of FASB Statement No. 26 and Technical Bulletin No. 79-11 (SFAS 98), the Company should have reflected an asset on its balance sheet for the costs paid by the lessor to
construct its headquarters facilities, as well as a corresponding liability, because the Company was the deemed owner of the headquarters facilities for accounting purposes during the construction periods. Upon completion of
construction, the Company did not meet the sale-leaseback criteria under SFAS 98 and therefore should have treated the leases as financing obligations and the assets and corresponding liabilities would not be derecognized. The Company
has historically accounted for these leases as operating leases under SFAS No. 13, Accounting for Leases(SFAS 13), whereby the total minimum lease payment obligations under the leases was recognized as monthly rent expense
on a straight-line basis over the terms of the leases.The restatement adjustments do not affect the total cash payments the Company has made or is obligated to make under the lease agreements, nor do they change the total expense to be
recognized over the lease terms. However, the timing and nature of expenses in the statement of operations is different under this treatment as compared to operating lease treatment. Specifically, the Company should have recognized land lease
expense, depreciation expense on the assets it is deemed to own and interest expense on the associated lease financing obligations.

Therefore the Company has restated its consolidated balance sheets as of December 31, 2007 and 2006, and its consolidated statements of operations, stockholders equity, cash flows and comprehensive income (loss) for each of the
years in the three-year period ended December 31, 2007 and each of the quarters in 2007 and 2006, to reflect the restatement adjustments applicable to those periods.

3. Property and Equipment (As Restated)

Property and equipment are stated at cost. The cost of buildings and improvements for our leased San Jose, California headquarters facilities, for which
we are the deemed owner for accounting purposes only, includes both the costs paid for directly by the Company and the costs paid for by the builder (lessor).

Accounting for buildings and improvements

In December 1999, the Company entered into a lease
agreement with a real estate developer for its existing corporate headquarters in San Jose, California. This agreement requires minimum rental payments for ten years totaling approximately $20.6 million and also required that the Company
provide a $3.0 million security deposit, which requirement has since been reduced to $1.2 million. The Company satisfied the security deposit requirement by causing to have issued a standby letter of credit (LOC) in July 2000.
The LOC is subject to annual renewals and is currently secured by a $10.0 million line of credit at the bank that issued the LOC. The line of credit is maintained primarily for the purpose of providing standby letters of credit as required
under the Companys lease agreements, as well as for providing standby letters of credit that arise from time to time in the general course of business. As of June 30, 2007 and December 31, 2006, no amounts had been drawn against the
line of credit or the letters of credit.

In October 2000, the Company entered into another lease agreement with the same real estate
developer for an additional building at its headquarters site. Construction on the second building was completed in May 2003, at which time monthly rental payments commenced. This second lease agreement also requires minimum rental

payments for ten years totaling approximately $23.4 million. In addition, this second lease agreement also required a security deposit of $5.0 million.
The Company satisfied this security deposit requirement by causing to have issued another LOC in October 2001. This LOC is also subject to annual renewals and is currently secured by a line of credit at the bank that issued it.

Both the December 1999 and October 2000 leases permit the Company to exercise an option to extend the respective lease for two sequential five-year
terms.

As discussed in Note 2, the Company has accounted for the two buildings at its San Jose, California headquarters site under
EITF 97-10 and SFAS 98. EITF 97-10 applies to entities involved with the construction of an asset that will be leased when the construction project is completed. During construction, the Company paid for certain tenant improvements,
including structural elements of the buildings and, in accordance with EITF 97-10, is therefore the deemed owner for accounting purposes of the two buildings at its San Jose, California headquarters site. Accordingly, the Company
recorded assets for the total costs of the buildings and improvements, including the costs paid by the lessor (the legal owner of the buildings that the Company leases), with corresponding liabilities for the costs paid by the lessor. Upon
completion of construction of each building, the Company did not meet the sale-leaseback criteria in SFAS 98 for derecognition of the building assets and liabilities. Therefore, the leases are accounted for as financing obligations.

For the December 1999 and October 2000 lease agreements, the Company initially recorded assets and corresponding lease financing obligations for the
building and improvement costs paid by the lessor in the amount of $12.0 million and $15.2 million, respectively. The Company has recorded depreciation expense associated with the building and improvement costs paid by the lessor of
$681,000 in each of the three-month periods ended June 30, 2007 and 2006 and $1.4 million in each of the six-month periods ended June 30, 2007 and 2006. As of June 30, 2007 and December 31, 2006, the net book value of the
buildings and improvements paid for by the lessor was $13.9 million and $15.2 million, respectively.

Under the lease agreements,
a portion of each lease payment is accounted for as an operating lease of land and recorded as expense on a straight-line basis over the terms of the respective leases which includes the construction periods. The remaining lease payments are
considered to be payments of principal and interest on the lease financing obligations. For the three months ended June 30, 2007 and 2006, land lease expense was $113,000 for each quarter, principal reductions on the lease financing obligations
were $639,000 and $571,000, respectively, and interest expense was $308,000 and $350,000, respectively. For the six months ended June 30, 2007 and 2006, land lease expense was $225,000 for each period, principal reductions on the lease
financing obligations were $1.3 million and $1.1 million, respectively, and interest expense was $627,000 and $710,000, respectively.

4.
Short-Term Investments

As of June 30, 2007, the Companys available-for-sale securities had contractual maturities from six
to twenty-four months and an average remaining term to maturity of eight months. The fair value of available-for-sale securities was determined based on quoted market prices at the reporting date for those instruments. As of June 30, 2007, the
amortized cost basis, aggregate fair value, and gross unrealized holding losses by major security type were as follows (in thousands):

annually thereafter, expires in December 2007. Please refer to Note 13, Related Party, for additional information regarding the Companys agreement with Enel.

8. Commitments and Contingencies (As Restated)

Lease Commitments (As Restated)

As discussed in Note 3, the December 1999 and October 2000 leases of our corporate headquarters facilities are accounted for under EITF 97-10 and
SFAS 98.

In addition, the Company leases facilities under operating leases for its sales, marketing, and product development
personnel located elsewhere within the United States and in nine foreign countries throughout Europe and Asia including a land lease for accounting purposes associated with the Companys corporate headquarters facilities. These operating leases
expire on various dates through 2018, and in some instances are cancelable with advance notice. Lastly, the Company also leases certain equipment and, for some of its sales personnel, automobiles. These operating leases are generally less than five
years in duration.

Royalties

The
Company has certain royalty commitments associated with the shipment and licensing of certain of its 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 as a component of cost of product revenues in our condensed statements of income, was approximately $150,000 during the quarter ended June 30, 2007, and $102,000 for the same period in 2006. Royalty expense was approximately
$299,000 for the six months ended June 30, 2007, and $211,000 for the same period in 2006.

##### Table of Contents

The Company will continue to be obligated for royalty payments in the future associated with the shipment
and licensing of certain of its products. The Company is currently unable to estimate the maximum amount of these future royalties. However, such amounts will continue to be dependent on the number of units shipped or the amount of revenue generated
from these products.

Warranties

The
Company typically sells its products with a limited warranty against defects in manufacture or performance. When evaluating the reserve for warranty costs, management takes into consideration the term of the warranty coverage, the quantity of
product in the field that is currently under warranty, historical return rates, and historical costs of repair. In addition, certain other applicable factors, such as technical complexity, may also be taken into consideration when historical
information is not yet available for recently introduced products. Estimated reserves for warranty costs are recorded at the time of shipment. In addition, additional warranty reserves may be established when the Company becomes aware of a specific
warranty related problem, such as a product recall. Such additional warranty reserves are based on the Companys current estimate of the total out-of-pocket costs expected to be incurred to resolve the problem, including, but not limited to,
costs to replace or repair the defective items and shipping costs. The reserve for warranty costs was $270,000 as of June 30, 2007 and $224,000 as of December 31, 2006.

Guarantees

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

As permitted
under Delaware law, the Company has entered into agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Companys 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 the Company could be required to make under these indemnification agreements is
unlimited. However, the Company has directors and officers insurance coverage that would enable it to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of the
applicable insurance coverage is minimal.

Taxes

The Company conducts 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
the Companys operations in that particular location. While the Company strives 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 accounting principles generally accepted in the United States of America, the Company makes 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 the Company believes that, as of June 30, 2007, it has adequately provided for such contingencies. However, it is possible that the Companys 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 the Company conducts its operations.

Legal Actions

From time to time, in the ordinary
course of business, the Company is 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, 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

##### Table of Contents

such contingencies as of June 30, 2007, 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.

9. 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):

11. Segment Disclosure (As Restated)

The Company operates in one principal industry segment: the design, manufacture, and sale of control networking infrastructure products; and markets its products primarily to the building automation, industrial
automation, transportation, utility, and home automation markets. The Companys products provide the infrastructure and support required to implement and deploy open and interoperable control networks, enabling everyday devices  such as
air conditioners, appliances, electricity meters, light switches, thermostats, and valves  to be made smart and inter-connected. The Company also provides a range of services to its customers that consist of technical support, training courses
covering its networking technology and products, and custom software development.

In total, the Company offers a wide ranging set of
control networking infrastructure products and services. Any given customer may purchase a subset of such products and services that are appropriate for that customers application. For example, a utility might use the Companys Networked
Energy Services products to more efficiently manage its distribution grid, while another customer who installs building controls might use the Companys LONWORKS Infrastructure transceivers and internet servers to
enable the monitoring and management of building occupancy and energy consumption.

The Company manages its business primarily on a
geographic basis. The Companys geographic areas are comprised of three main groups: the Americas; Europe, Middle East and Africa (EMEA); and Asia Pacific / Japan (APJ). Each geographic area provides products and
services as further described in Item 2, Managements Discussion and Analysis of Financial Condition and Results of Operations. The Company evaluates the performance of its geographic areas based on profit or loss from operations. Profit
or loss for each geographic area includes sales and marketing expenses and other charges directly attributable to the geographic area and excludes certain expenses that are managed outside the geographic area. Costs excluded from geographic area
profit or loss consist primarily of unallocated corporate expenses, which are comprised of product development costs, corporate marketing costs, and other general and administrative expenses, which are separately managed. The Companys
long-lived assets include property and equipment, goodwill, loans to certain key employees, purchased technology, and deposits on its



19

##### Table of Contents

leased facilities. Long-lived assets are attributed to geographic areas based on the country where the assets are located. As of June 30, 2007 and
December 31, 2006, long-lived assets of approximately $37.3 million (as restated) and $37.4 million (as restated), respectively, were domiciled in the United States. Long-lived assets for all other locations are not material to the
consolidated financial statements. Assets and the related depreciation and amortization are not reported by geography because that information is not reviewed by the executive staff when making decisions about resource allocation to the geographic
areas based on their performance.

The Company typically sells its products through a direct sales organization and select third-party
electronics representatives in North America. Outside North America, the Company typically sells its products through direct sales organizations in EMEA and APJ, value-added resellers, and local distributors. Revenues are attributed to geographic
areas based on the country where the customer is domiciled. Summary information by geography for the three and six months ended June 30, 2007 and 2006 is as follows (in thousands) (as restated):

Products sold to Enel and its designated manufacturers (see discussion of Enel below in Note 13- Related Party)
accounted for approximately $3.8 million, or 14.4% of total revenues for the quarter ended June 30, 2007, and $6.9 million, or 35.4% for the same period in 2006; and $5.0 million, or 7.6% of total revenues for the six months ended
June 30, 2007, and $7.1 million, or 23.4% for the same period in 2006. For the quarter ended June 30, 2007, 95.9% of the revenues under the Enel program were derived from products shipped to customers in APJ, while the remaining 4.1% from
customers in EMEA. For the six months ended June 30, 2007, 95.3% of the revenues derived from products shipped under the Enel program were from customers in APJ and the remaining 4.7% from customers in EMEA.

12. Income Taxes

We adopted FASB Interpretation
No. 48 (FIN 48), Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109, on January 1, 2007. This interpretation prescribes a recognition threshold and measurement attributes
for the financial statement recognition and measurement of a tax position taken or expected to be taken on a tax return. FIN 48 also provides guidance on de-recognition of tax benefits, classification on the balance sheet, interest and penalties,
accounting in interim periods, and disclosure and transition.

As a result of the implementation of FIN 48, the Company recognized no
material adjustment in the liability for unrecognized income tax benefits. The Company had unrecognized tax benefits of approximately $1.2 million as of January 1, 2007, all of which, if recognized, would result in a reduction of the
Companys effective tax rate. There have been no significant changes to the Companys unrecognized tax benefits since January 1, 2007.

In connection with the adoption of FIN 48, the Company will continue to include interest and penalties related to uncertain tax positions as a component of income tax, which was immaterial for the three and six months
ended June 30, 2007. We do not believe it is reasonably possible that the Companys unrecognized tax benefits will change significantly within the next twelve months.

The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The tax years
1992-2006 remain open to examination by the federal and most state tax authorities due to certain net operating loss and credit carryforward positions.

The provision for income taxes for the quarters and six month periods ended June 30, 2007 and 2006 includes a provision for Federal, state and foreign taxes based on the annual estimated effective tax rate
applied to the Company and its subsidiaries for the year. The difference between the statutory rate and the Companys effective tax rate is primarily due to the impact of foreign taxes.

|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. Our actual results may differ materially.

RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

During the preparation of our financial results for the quarter ended March 31, 2008, we identified an error in our previously reported equity compensation expense and determined we had inappropriately accounted
for the 1999 and 2001 leases of our San Jose, California corporate headquarters facilities.

Restatement of stock-based compensation
expense:We identified an error in our previously reported stock-based compensation expense for the years ended December 31, 2007, 2006 and 2005 and each of the quarterly periods in 2007 and 2006. The error was isolated to share awards
and does not affect the other forms of our equity compensation awards, namely stock options and stock-settled stock appreciation rights. While the grant date fair value of the share awards was determined correctly in accordance with Statement of
Financial Accounting Standard (SFAS) No. 123R (revised 2004), Share-Based Payment (SFAS 123R), the amount of expense associated with these awards that was recognized in 2007, 2006 and 2005 was not correct.
The error was caused by a misapplication of the widely-used equity compensation software application we use to manage and account for our equity compensation awards. This misapplication caused the expense associated with these share awards to be
calculated using the straight-line, single-option method rather than the accelerated, multiple-option method, which we had elected to use for all of our equity compensation awards. Use of the straight-line, single-option method resulted in
understatements of stock-based compensation expense in 2007, 2006 and 2005 of $1.2 million, $535,000 and $263,000, respectively. For the three months ended June 30, 2007 and 2006, stock-based compensation expense was understated by
$188,000 and $164,000, respectively. For the six months ended June 30, 2007 and 2006, stock-based compensation expense was understated by $341,000 and $309,000, respectively.

Restatement related to the leases of our San Jose, California headquarters facilities: In connection with the restatement of stock-based
compensation expense, KPMG LLP, our independent registered public accounting firm, brought to our attention that we had inappropriately accounted for the leases of our corporate headquarters facilities that were entered into in 1999 and 2001. Under
the guidance in Emerging Issues Task Force Issue No. 97-10,The Effect of Lessee Involvement in Asset Construction (EITF 97-10), and SFAS No. 98,Accounting for Leases: Sale-Leaseback transactions Involving Real
Estate; Sales-Type Leases of Real Estate; Definition of the Lease Term; Initial Direct Costs of Direct Financing Leases; an amendment of FASB Statements No. 13, 66, and 91 and a rescission of FASB Statement No. 26 and Technical Bulletin
No. 79-11 (SFAS 98), we should have reflected an asset on our balance sheet for the costs paid by the lessor to construct our headquarters facilities, as well as a corresponding liability, because we were the deemed
owner of the headquarters facilities for accounting purposes during the construction periods. Upon completion of construction, we did not meet the sale-leaseback criteria under SFAS 98 and therefore should have treated the leases
as financing obligations and the assets and corresponding liabilities would not be derecognized. We had historically accounted for these leases as operating leases under SFAS No. 13, Accounting for Leases(SFAS 13), whereby
the total minimum lease payment obligations under the leases were recognized as monthly rent expense on a straight-line basis over the terms of the leases.The restatement adjustments do not affect the total cash payments we have made or are
obligated to make under the lease agreements, nor do they change the total expense to be recognized over the lease terms. However, the timing and nature of expenses in the statement of operations is different under this treatment as compared to
operating lease treatment. Specifically, we should have recognized land lease expense, depreciation expense on the assets we are deemed to own and interest expense on the associated lease financing obligations.

Our management and the Audit Committee of our Board of Directors have concluded that these errors in our
consolidated financial statements were unintentional, and no misdeed or fraud was involved in any respect. The Audit Committee also determined that the error in stock-based compensation expense was in no way caused by any backdating of or similar
improper activity involving stock option grants.

Therefore we have restated our condensed consolidated balance sheets as of June 30,
2007, and December 31, 2006, and our condensed consolidated statements of operations and cash flows for the three- and six-month periods ended June 30, 2007 and 2006, to reflect the restatement adjustments applicable to those periods. We
will also file amendments to our 2007 Form 10-K and Forms 10-Q for each of the quarters ended March 31 and September 30, 2007. The amended 2007 filings will include restated information for the periods affected by these
restatements.

The effects of all restatement adjustments on our condensed consolidated balance sheets as of June 30, 2007, and
December 31, 2007 and 2006 are as follows:

The correction of the accounting for our San Jose, California headquarters facilities leases
required us to calculate the adjustments by year beginning with the year ended December 31, 2000. The cumulative effect of the restatement adjustments related to the lease accounting errors for the years 2000 through 2004 is reported as a
$2.5 million increase to the 2005 beginning accumulated deficit balance. The financial statement effects of all restatement adjustments by year are summarized in the following table (in thousands):

Included in Note 2 of Notes to Condensed Consolidated Financial Statements in this Report are tables that
present the effects of all restatement adjustments on the condensed consolidated financial statements reconciling the previously reported data to the as restated data for the Condensed Consolidated Balance Sheets as of June 30, 2007
and December 31, 2006, and the Condensed Consolidated Statements of Operations and Cash Flows for each of the three- and six-month periods ended June 30, 2007 and 2006.

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 nine 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.

We have been investing in products for use by electricity utilities in
management of electricity distribution. We refer to these products (and related services) as our networked energy services, or NES, offerings. We began to receive modest amounts of NES revenue in 2004, which increased to approximately $883,000 in
2005 and decreased slightly to $791,000 in 2006. During the first six months of 2007, NES revenue increased significantly to $34.3 million. We 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.

During the first and second quarters of 2006, we revised our revenue recognition methodology for
sales made to the distributors of our LWI products. Under the revised methodology, we now defer revenue, as well as cost of goods sold, on items shipped to these distributors that remain in their inventories at quarter-end. The revision
significantly reduced our first and second quarter 2006 revenues, but did not have an impact on cash flows from operations or require any changes to our historical financial statements. A more thorough explanation of this revision can be found later
in this report in the LONWORKS Infrastructure revenues and EBV revenues sections of our discussion on Results of Operations.

We have a history of losses and, we incurred a loss for the quarter and six months ended June 30, 2007 and expect to incur an operating loss for the
full year ending December 31, 2007. This expectation is due primarily to two factors. First, as we expected in both 2005 and 2006, revenues from the Enel Project decreased significantly as compared to prior periods as the deployment phase of
the Contatore Elettronico project came to an end. We expect that during 2007, Enel Project revenues attributable to the two recently signed agreements with Enel will rise only slightly from 2006 levels. While we expect our NES revenues to increase
substantially during 2007, we do not currently believe they will increase rapidly enough to return us to an operating profit for the full year ending December 31, 2007.

The second factor contributing to our expectation for losses in 2007 relates to the fact that, effective January 1, 2006, we began recording
compensation expense associated with stock options and other forms of equity compensation as required under SFAS 123R. For the year ended December 31, 2006, the adoption of this new accounting standard resulted in an increase in equity
compensation expenses of approximately $4.3 million as compared to the same period in 2005. We expect equity compensation expense in 2007 will be higher than that charged in 2006.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the United States of America. 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, allowance for doubtful accounts, inventories, commitments and
contingencies, income taxes, and asset impairments. 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.

We believe the following critical accounting estimates relate to those policies that are most important to the presentation of our consolidated financial statements and require the most difficult, subjective and complex judgments.

Stock-Based Compensation. Effective January 1, 2006, we adopted the provisions of and account for stock-based compensation in accordance with
SFAS 123R. We elected the modified-prospective method, under which prior periods are not revised for comparative purposes. Under the fair value recognition provisions of this statement, stock-based compensation cost is measured at the grant date
based on the calculated fair value of the award and is recognized as expense ratably over the requisite service period, which is the vesting period.

We currently use the Black-Scholes-Merton (BSM) option-pricing model to determine the calculated fair value of stock options. The determination of the calculated fair value of stock-based payment awards on
the date of grant using the BSM option-pricing model is affected by our stock price on the date of grant, as well as a number of highly complex and subjective variables. These variables include the expected volatility of our stock price over the
expected term of the option, actual and projected employee stock option exercise behaviors, risk-free interest rates, and expected dividends.

We estimate the expected term of options granted using the simplified method as illustrated in SEC Staff Accounting Bulletin No. 107 (SAB 107). Under the simplified method, the expected term is calculated by taking the
average of the vesting term and the contractual term of the option. The expected volatility is based on the historical volatility of our common stock over the most recent period commensurate with the expected life of the option, and does not include
any implied volatility as there are currently no market traded options on our stock that meet the criteria required for reliance on implied volatility in accordance with SAB 107. We base the risk-free interest rate that we use in the BSM
option-pricing model on U.S. Treasury issues in effect at the time of option grant that have remaining terms similar to the expected term of the option. We have never paid cash dividends on our common stock, and do not anticipate paying cash
dividends in the foreseeable future. Therefore, we use an expected dividend yield of zero in the BSM option-pricing model.

SFAS 123R also
requires us to record compensation expense for stock-based compensation net of estimated forfeitures, and to revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate
pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. All share-based payment awards are amortized using the multiple option method over their requisite service period, which is
generally the vesting period.

There are significant differences among valuation models, and there is a possibility that we will adopt
different valuation models in the future. This may result in a lack of consistency in future periods and may materially affect the calculated fair value estimate of stock-based payments. It may also result in a lack of comparability with other
companies that use different models, methods, and assumptions. The BSM option-pricing model was developed for use in estimating the calculated fair value of traded options that have no vesting or hedging restrictions and that are fully transferable,
characteristics that are not present in our option grants.

Existing valuation models, including the BSM and lattice binomial models, may
not provide reliable measures of fair values of our stock-based compensation. Consequently, there is a risk that our estimates of the calculated fair values of our stock-based compensation awards on the grant dates may be significantly different
from the actual values realized, if any, upon the exercise, expiration, early termination, or forfeiture of those stock-based payments

in the future. For example, our employee stock options may expire worthless or otherwise result in zero intrinsic value as compared to the calculated fair
values originally estimated on the grant date and reported in our financial statements. Alternatively, value may be realized from these instruments that is significantly higher than the calculated fair values originally estimated on the grant date
and reported in our financial statements. There is currently no market-based mechanism or other practical application to verify the reliability and accuracy of the estimated fair values resulting from these valuation models, nor is there a means to
compare and adjust the estimates to actual values.

If factors change and we employ different assumptions for estimated stock-based
compensation expense in future periods, or if we decide to use a different option-pricing model, stock-based compensation expense in those future periods may differ significantly from what we have recorded in the current period and could materially
affect our operating results and earnings per share.

Sales Returns and Allowances. We sell our products and services to OEMs, systems integrators,
and our other customers directly through our sales force and indirectly through distributors located in the geographic markets that we serve. Sales to certain distributors are made under terms allowing limited rights of return. Sales to EBV, our
largest distributor, accounted for 16.3% of total net revenues for the quarter ended June 30, 2007, and 22.0% for the same period in 2006; and 13.7% of total revenues for the six months ended June 30, 2007 and 22.3% for the same period in
2006. Worldwide sales to distributors, including those to EBV, accounted for approximately 24.1% of total net revenues for the quarter ended June 30, 2007, and 25.5% for the same period in 2006, and 20.1% of total net revenues for the six
months ended June 30, 2007 and 29.2% for the same period in 2006.

Net revenues consist of product and service revenues reduced by
estimated sales returns and allowances. Provisions for estimated sales returns and allowances are recorded at the time of sale, and are based on managements estimates of potential future product returns and allowances related to product
revenues in the current period. In evaluating the adequacy of our sales returns and other allowances, management analyzes historical returns, current and historical economic trends, contractual terms, and changes in customer demand and acceptance of
our products.

Other than standard warranty repair work, Enel and its designated contract meter manufacturers do not have rights to return
products we ship to them. However, our agreement with Enel contains an acceptance provision, whereby Enel is entitled to inspect products we ship to them to ensure the products conform, in all material respects, to the products
specifications. Once the product has been inspected and approved by Enel, or if the acceptance period lapses before Enel inspects or approves the products, the goods are considered accepted. Prior to shipping our products to Enel, we perform
detailed reviews and tests to ensure the products will meet Enels acceptance criteria. We do not ship products unless they have passed these reviews and tests. As a result, we record revenue for these products upon shipment to Enel. If Enel
were to subsequently properly reject any material portion of a shipment for not meeting the agreed upon specifications, we would defer the revenue on that portion of the transaction until such time as Enel and we were able to resolve the
discrepancy. Such a deferral could have a material impact on the amount and timing of our Enel related revenues.

Our allowances for sales
returns and other sales-related reserves were approximately $881,000 as of June 30, 2007, and $791,000 as of December 31, 2006.

Allowance for
Doubtful Accounts. We typically sell our products and services to customers with net 30-day payment terms. In certain instances, payment terms may extend to as much as net 90 days. For a customer whose credit-worthiness does not meet our minimum
criteria, we may require partial or full payment prior to shipment. Alternatively, customers may be required to provide us with an irrevocable letter of credit prior to shipment.

We evaluate the collectibility of our accounts receivable based on a combination of factors. In circumstances where we are aware of a specific
customers inability to meet its financial obligations to us, we record a specific allowance against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected. These determinations are made based
on several sources of information, including, but not limited to, a specific customers payment history, recent discussions we have had with the customer, updated financial information for the customer, and publicly available news related to
that customer. For all other customers, we recognize allowances for doubtful accounts based on the length of time the receivables are past due, the current business environment, the credit-worthiness of our overall customer base, changes in our
customers payment patterns, and our historical experience. If the financial condition of our customers were to deteriorate, or if general economic conditions were to worsen, additional allowances may be required in the future, which could
materially impact our results of operations and financial condition. Our allowance for doubtful accounts was $185,000 as of June 30, 2007, and $250,000 as of December 31, 2006.

Inventory Valuation. At each balance sheet date, we evaluate our ending inventories for excess quantities and
obsolescence. This evaluation includes analyses of sales levels by product and projections of future demand. Inventories on hand, in excess of one years forecasted demand, are not valued. In addition, we write off inventories that we consider
obsolete. We consider a product to be obsolete when one of several factors exists. These factors include, but are not limited to, our decision to discontinue selling an existing product, the product has been re-designed and we are unable to rework
our existing inventory to update it to the new version, or our competitors introduce new products that make our products obsolete. We adjust remaining inventory balances to approximate the lower of our cost or market value. If future demand or
market conditions are less favorable than our projections, additional inventory write-downs may be required and would be reflected in cost of sales in the period the revision is made.

Warranty Reserves. We evaluate our reserve for warranty costs based on a combination of factors. In circumstances where we are aware of a specific warranty related problem, for example a product recall, we
reserve an estimate of the total out-of-pocket costs we expect to incur to resolve the problem, including, but not limited to, costs to replace or repair the defective items and shipping costs. When evaluating the need for any additional reserve for
warranty costs, management takes into consideration the term of the warranty coverage, the quantity of product in the field that is currently under warranty, historical warranty-related return rates, historical costs of repair, and knowledge of new
products introduced. If any of these factors were to change materially in the future, we may be required to increase our warranty reserve, which could have a material negative impact on our results of operations and our financial condition. Our
reserve for warranty costs was $270,000 as of June 30, 2007, and $224,000 as of December 31, 2006.

Deferred Income Taxes. We record a
valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. Based on our historical net operating losses, and the uncertainty of our future operating results, we have recorded a valuation
allowance that fully reserves our deferred tax assets. If we later determine that, more likely than not, some or all of the net deferred tax assets will be realized, we would then need to reverse some or all of the previously provided valuation
allowance. Our deferred tax asset valuation allowance was $61.2 million as of December 31, 2006.

Valuation of Goodwill. We assess the
impairment of goodwill on an annual basis during the quarter ending March 31 and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors we consider important which could trigger an
impairment review include the following:



| |  |  | significant underperformance relative to expected historical or projected future operating results;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | significant changes in the manner or use of the acquired assets or the strategy for our overall business;
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | significant negative industry or economic trends; and
| | - |  | -----------------------------------------------------



| |  |  | significant changes in the composition of the intangible assets acquired.
| | - |  | -------------------------------------------------------------------------

Our review during the quarter ended March 31, 2007 indicated no impairment. If, as a result of an annual or any other impairment review that we
perform in the future, we determine that there has been an impairment of our goodwill, we would be required to take an impairment charge. Such a charge could have a material adverse impact on our financial position and/or operating results.

The $7.3 million increase in total revenues for the quarter ended June 30, 2007 as compared
to the same period in 2006 was primarily the result of a $9.1 million increase in NES revenues and a $1.3 million increase in LONWORKS Infrastructure revenues, partially offset by a $3.0 million decrease in Enel Project
revenues. The $35.8 million increase in total revenues for the six months ended June 30, 2007 as compared to the same period in 2006 was primarily the result of a $33.8 million increase in NES revenues and a $4.1 million increase in
LONWORKS Infrastructure revenues, partially offset by a $2.1 million decrease in Enel Project revenues.

NES revenues generated during the three and six months ended June 30, 2007 were primarily
related to large scale deployments of our NES system products. NES revenues generated during the quarter and six months ended June 30, 2006 were primarily related to the completion of system trials and, to a lesser extent, shipments of NES
products.

We expect that, during 2007, shipments of our NES products will continue to increase over 2006 levels. Our ability to recognize
revenue on these shipments depends on several factors, including, but not limited to, delivery to the customer of all of the software called for in any given agreement, modification of the 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 NES product shipments until certain conditions are met in a future period. In some instances, the reasons for these deferrals may not be fully under our control, which could result in the actual timing of revenue being
significantly different than we currently anticipate.

We also expect that some foreign utilities will require us to price our NES system
in the respective utilitys local currency, which will expose us to foreign currency risk. For the six months ended June 30, 2007, the portion of our NES revenues conducted in currencies other than the U.S. dollar,
principally the Australian dollar, was about $300,000, or 0.9%. There were no NES revenues conducted in foreign currencies during the six months ended June 30, 2006. In most cases, in the event of a significant contract award, 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 our 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.

##### Table of Contents

Our LONWORKS Infrastructure 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. Both the $1.3 million increase in LONWORKS Infrastructure revenues for the quarter ended
June 30, 2007 as compared to the same period in 2006, and the $4.1 million increase for the six months ended June 30, 2007 as compared to the same period in 2006, were primarily attributable to the one-time effect of revisions we made in
2006 to our revenue recognition methodology for sales made to our distributor partners. During the first quarter of 2006, we modified our revenue recognition method for sales made to our European distributor, EBV (see EBV revenue discussion below).
Under the revised method, revenue on sales made to EBV is deferred until EBV sells the products through to its end use customers. During the second quarter of 2006, we completed a similar revision to our revenue recognition methodology for sales
made to our Asian distributor partners. This revision was necessary as, during the quarter, we modified our agreements with our Asian distributor partners. These contractual modifications, which allow the distributors to return certain of their
excess inventory, were made to address changing business conditions in our Asian markets and to expand our customer base there. The revenue recognition methodology revisions for EBV and our Asian distributors resulted in one-time reductions in
revenue of approximately $1.0 million during the second quarter of 2006, and $3.9 million during the six months ended June 30, 2006.

Excluding the impact of these revenue recognition revisions, LONWORKS Infrastructure revenues increased by approximately $252,000 during the quarter ended June 30, 2007 as compared to the same period in
2006, and by approximately $224,000 for the six months ended June 30, 2007 as compared to the same period in 2006. We believe these increases are due, at least in part, to our customers utilization of our products in new applications,
such as energy management and street lighting controls.

Also impacting the fluctuations in LONWORKS
Infrastructure revenues between the two quarters ended June 30, 2007 and 2006, and the two six month periods ended June 30, 2007 and 2006, were the unfavorable impacts of exchange rates on sales made in foreign currencies, principally the
Japanese Yen. These exchange rate fluctuations resulted in a $37,000 decrease in LONWORKS Infrastructure revenues between the two quarterly periods, and a $45,000 decrease between the two six month periods.

We believe that, as long as current worldwide economic conditions do not deteriorate, full year 2007 LONWORKS
Infrastructure revenues will improve from the $49.4 million recorded in 2006. This expected improvement, however, will be subject to further fluctuations in exchange rates between the U.S. dollar and the foreign currencies in which we generate
revenues, principally the Japanese Yen. If the U.S. dollar were to strengthen against these currencies, our revenues would decrease. Conversely, if the U.S. dollar were to weaken against these currencies, our revenues would increase. The extent of
this exchange rate fluctuation increase or decrease will depend on the amount of sales conducted in foreign currencies and the magnitude of the exchange rate fluctuation from year to year. The portion of our LONWORKS
Infrastructure revenues conducted in currencies other than the U.S. dollar, principally the Japanese Yen, was about 6.3% for both the six months ended June 30, 2007 and the six months ended June 30, 2006. We do not currently expect that,
during the remainder of 2007, the amount of our LONWORKS Infrastructure revenues conducted in these or other foreign currencies will fluctuate significantly from that experienced in 2006. 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 LONWORKS Infrastructure 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.

In October 2006, we entered into two new agreements with Enel, a development and supply agreement and a
software enhancement agreement. Under the development and supply agreement, Enel will purchase additional metering kit and data concentrator products from us. Under the software enhancement agreement, we will provide software enhancements to Enel
for use in its Contatore Elettronico system. There were no revenues from either of these new agreements during 2006. The $3.8 million and $5.0 million of Enel project revenue recognized during the quarter and six months ended June 30, 2007,
respectively, related to initial shipments under the new development and supply agreement. Both the development and supply agreement and the software enhancement agreement expire on December 31, 2009, although delivery of products and services
can extend beyond that date and the agreements may be extended under certain circumstances.

Early in 2006, Enel asked us to provide them
with spare parts for use in their system in Italy. The $6.9 million and $7.1 million of Enel project revenue recognized during the quarter and six months ended June 30, 2006, respectively, represent shipments we made against that request. 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.

We believe that full year 2007 revenues attributable to the Enel project will increase over the $7.1 million reported in 2006 and will relate primarily to products shipped to Enel and its designated manufacturers

Sales to EBV, our largest distributor and the sole independent distributor of our products in
Europe, accounted for 16.3% of our total revenues for the quarter ended June 30, 2007 and 22.0% of our total revenues for the same period in 2006; and 13.7% of our total revenues for the six months ended June 30, 2007 and 22.3% for the
same period in 2006. While EBV revenues increased by only 2.2% during the quarter ended June 30, 2007 as compared to the same period in 2006, they increased substantially during the six months ended June 30, 2007 as compared to the same
period in 2006. The primary factor contributing to the $2.3 million increase between the six month periods was the fact that, during the first quarter of 2006, we revised our revenue recognition methodology for sales made to EBV. Under the revised
methodology, revenues, as well as cost of goods sold, are deferred on items shipped to EBV that remain in EBVs inventories at quarter-end. Revenue is then recognized on these products, along with the corresponding gross margin, when EBV sells
them to its customers in future periods. This revision resulted in a one-time revenue decrease of approximately $2.9 million for the quarter ended March 31, 2006. The revision did not have an impact on cash flows from operations or require any
changes to historical financial statements.

Excluding the impact of the accounting method revision, EBVs shipments to its customers
decreased by approximately $600,000 during the first half of 2007 as compared to the same period in 2006. We believe this decrease is the result of the Restriction of Hazardous Substances, or RoHS, regulations, which became effective in the European
Union July 1, 2006. Under these new rules, manufacturers such as Echelon were required to eliminate certain hazardous substances (e.g., lead, cadmium, mercury, etc.) from the products they sell into the region. We believe that many of
EBVs customers increased their purchases of our non-RoHS compliant products during the first half of 2006, prior to effective date of the new regulations. This resulted in a high level of EBV revenue during the first half of 2006.

We currently sell our products to EBV in U.S. dollars. Therefore, the associated revenues are not subject
to foreign currency exchange rate risks. However, EBV has the right, on notice to our company, to require that we sell our products to them in Euros.

Our contract with EBV, which has been in effect since 1997 and to date has been renewed annually thereafter, expires in December 2007. If our agreement with EBV is not renewed, or is renewed on terms that are less
favorable to us, our revenues could decrease and our future financial position could be harmed.

The $7.2 million increase in product revenues for the quarter ended June 30, 2007 as compared
to the same period in 2006 was primarily the result of a $9.0 million increase in NES product revenues and a $1.2 million increase in LONWORKS Infrastructure product revenues, partially offset by a $3.0 million decrease
in Enel Project revenues. The $35.7 million increase in product revenues for the six months ended June 30, 2007 as compared to the same period in 2006 was primarily the result of a $33.6 million increase in NES product revenues and a
$4.2 million increase in LONWORKS Infrastructure product revenues, partially offset by a $2.1 million decrease in Enel Project revenues.

The $94,000 increase in service revenues during the quarter ended June 30, 2007 as compared
to the same period in 2006, and the $115,000 increase during the six months ended June 30, 2007 as compared to the same period in 2006, were primarily due to an increase in NES support revenues, partially offset by a reduction in our
LONWORKS Infrastructure customer support and training revenues. Primarily due to the increase in NES service revenues associated with our large scale deployment projects, we currently expect that our full year 2007
service revenues will increase modestly from the $761,000 recorded in 2006.

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
warranty and excess and obsolete inventory reserves. 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.

Both the 19.3 percentage
point decrease in gross margin during the second quarter of 2007, as well as the 25.9 percentage point decrease during the first six months of 2007, were due primarily to the mix of revenues reported. In each case, the proportion of our
revenues attributable to sales of our NES system products increased significantly as compared to the same periods in 2006. In general, gross margins generated from sales of our NES system products are much lower than those generated from both sales
of our LONWORKS Infrastructure products and services as well as sales made under the Enel Project. As a result, when NES revenues are higher as a percentage of overall revenues, as they were during the quarter and six
months ended June 30, 2007, overall gross margins will be lower. Conversely, when NES revenues comprise a lower percentage of overall revenues, as they were during the quarter and six months ended June 30, 2006, overall gross margins will
be higher.

Partially offsetting the decrease in gross margins during the three and six months ended June 30, 2007 as compared to the
same periods in 2006 were the impacts of higher revenues. As discussed above, a portion of our cost of goods sold relates to indirect costs. Some of these costs do not increase or decrease in conjunction with revenue levels, but rather remain
relatively constant from quarter to quarter. As a result, when revenues increase, as they did in the quarter and six months ended June 30, 2007 as compared to the same periods in 2006, gross margins are favorably impacted.

We expect that, for full year 2007, overall gross margin will decrease significantly from the 58.2% experienced in 2006 due to the significant increase
we expect in NES revenues.

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

The $976,000 and $1.8 million increases in product development expenses for the quarter and six month periods ended June 30, 2007 as compared to the
same periods in 2006 were primarily due to increases in compensation expenses for our product development personnel, fees paid to third party service providers, and equipment and supplies used in the development process.

We expect that, for full year 2007, product development expenses will increase over 2006 levels. This increase will primarily be the result of increased
development efforts related to our NES system products.

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 $140,000 reduction in sales and marketing expenses during the quarter ended June 30, 2007 as compared to the same period in 2006 was primarily
the result of a decrease in costs associated with tradeshows. The $125,000 increase in sales and marketing expenses during the six months ended June 30, 2007 as compared to the same period in 2006 was primarily due to increases in compensation
related expenses for our sales and marketing personnel.

Also contributing to the changes in sales and marketing expenses between 2006 and
2007 were the impacts of foreign currency exchange rate fluctuations between the U.S. dollar and the local currencies in several of the foreign countries in which we have operations, including the Euro, the British Pound Sterling, and the
Japanese Yen. These exchange rate fluctuations caused sales and marketing expenses to increase by approximately $74,000 during the second quarter of 2007 as compared to the same period in 2006, and to increase by approximately $192,000 during the
six months ended June 30, 2007 as compared to the same period in 2006.

We expect that, during 2007, our sales and marketing expenses
will increase over 2006 levels. In addition, if the United States dollar were to weaken against the foreign currencies where we do business, our sales and marketing expenses could increase further. 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,
accounting, and administrative personnel, professional fees for legal and accounting services rendered to the company, facility costs, insurance, and other general corporate expenses.

Both the $499,000 and $802,000 increases in general and administrative expenses during the quarter and six months ended June 30, 2007, respectively,
as compared to the same periods in 2006, were primarily attributable to increases in compensation related expenses for our executive, accounting, and administrative personnel, and to a lesser extent, fees paid to our independent accountants and
other third party service providers.

We believe that, during 2007, general and administrative costs will increase modestly above 2006
levels.

Interest and other income, net primarily reflects interest earned by our company on cash and
short-term investment balances. In addition, foreign exchange translation gains and losses related to short-term intercompany balances are also reflected in this amount.

During the second quarter of 2007, interest and other income, net increased by approximately $84,000 as compared to the same period in 2006. This increase was primarily due to a $168,000 reduction in foreign exchange
translation losses, partially offset by a $101,000 decrease in interest income. During the six months ended June 30, 2007, interest and other income, net increased by approximately $187,000 as compared to the same period in 2006. As was the
case with the change between the two quarterly periods, this increase was primarily due to a $244,000 reduction in foreign exchange translation losses, partially offset by a $78,000 decrease in interest income. The reduction in interest income for
both the quarter and six months ended June 30, 2007 as compared to the same periods in 2006 is primarily the result of a reduction in our average invested cash balance between the periods.

Although interest rates have increased substantially since June 2004, we expect that our anticipated operating losses for 2007 will require us to use a
portion of our existing cash and short-term investment portfolio to fund ongoing business operations. In addition, we may decide to continue repurchasing our common stock in accordance with our board of directors approved stock repurchase program,
which expires in March 2008. As a result, we expect that the average amount of our invested cash will decrease during 2007, which will result in reduced interest income if interest rates remain unchanged. In addition, future fluctuations in the
exchange rates between the United States dollar and the currencies in which we maintain our short-term intercompany balances (principally the European Euro and the British Pound Sterling) will also affect our interest and other income, net.

In December 1999 and October 2000, we entered into two separate lease agreements with a local real estate developer for
the two buildings we currently occupy at our San Jose headquarters site. As discussed in Notes 2 and 3 of Notes to Condensed Consolidated Financial Statements in Item 1 of this Report, we have accounted for these leases in accordance with
EITF 97-10 and SFAS 98. The application of this accounting literature causes Echelon to be considered the deemed owner of the two buildings for accounting purposes only.

Accordingly, we have recorded assets and corresponding financing liabilities for an amount equal to these lessor paid construction costs. The monthly
rent payments we make to our lessor under our lease agreements are recorded in our financial statements as land lease expense and principal and interest on the lease financing obligations. Interest expense on lease financing obligations
reflects the portion of our monthly lease payments that is allocated to interest expense.

We expect that, during 2008, interest expense on
lease financing obligations will decrease from the amounts reported for 2007. 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. Therefore, a higher percentage of the payments we make in 2008 will be allocated
to principal repayment and less will be allocated to interest expense.

The provision for income taxes for 2007 includes a provision for federal, state and foreign taxes
based on our annual estimated effective tax rate for the year. The difference between the statutory rate and our effective tax rate is primarily due to the impact of foreign taxes. Income taxes of $107,000 and $80,000 for the quarters ended
June 30, 2007 and 2006, respectively, and $215,000 and $160,000 for the six months ended June 30, 2007 and 2006, respectively, consist primarily of taxes related to profitable foreign subsidiaries and various state minimum taxes.

##### Table of Contents

Although we expect to generate a loss before provision for income taxes in 2007, we will be required to
book income tax expense to cover, at a minimum, the foreign taxes owed on income generated by our profitable foreign subsidiaries as well as state minimum taxes. We currently expect our 2007 provision for income taxes will be slightly higher than
the amounts provided for in 2006.

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 Echelon 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. We lease our present corporate headquarters facility in San Jose, California, under two non-cancelable leases. The first lease agreement expires in 2011 and the second lease
agreement expires in 2013. Upon expiration, both lease agreements provide for extensions of up to ten years. As part of these lease transactions, we provided the lessor security deposits in the form of two standby letters of credit totaling
$6.2 million. The leases of our corporate headquarters facilities are accounted for under EITF 97-10 and SFAS 98 (see Notes 2 and 3 of Notes to Condensed Consolidated Financial Statements).

In addition, we lease facilities under operating leases for our sales, marketing, and product development personnel located elsewhere within the United
States and in nine foreign countries throughout Europe and Asia including a land lease for accounting purposes associated with our corporate headquarters facilities (see Notes as referenced above). These operating leases expire on various dates
through 2018, 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 that 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 could 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 on our consolidated statements of operations, was approximately $150,000 during the quarter ended June 30, 2007, and $102,000 for the same period in 2006, and $299,000 for the six months ended
June 30, 2007, and $211,000 for the same period in 2006.

##### Table of Contents

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 June 30, 2007, 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.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 June 30, 2007, 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 June 30, 2007, we raised $281.3 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 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 program during the three and six months ended June 30, 2007. Since inception, we have repurchased a total of 2,204,184 shares under the program at a cost of $16.1 million. As of
June 30, 2007, 795,816 shares are available for repurchase. The stock repurchase program will expire in March 2008.

As of June 30, 2007, we had $117.5 million in cash, cash equivalents, and short-term investments, a decrease of
$6.7 million as compared to December 31, 2006. 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 (as restated). Cash flows from operating activities have historically been driven by net income (loss) levels, adjustments for non-cash charges such as depreciation, amortization,
in-process research and development charges, and stock-based compensation, as well as fluctuations in operating asset and liability balances. Net cash used in operating activities was $5.0 million (as restated) for the six months ended June 30,
2007, a $2.4 million (as restated) decrease from the same period in 2006. During the six months ended June 30, 2007, net cash used in operating activities was primarily a result of our net loss of $10.9 million (as restated), changes in our
operating assets and liabilities of $348,000 (as restated), an increase in accrued investment income of $245,000, and a reduction in our bad debt reserve balance of $57,000, partially offset by stock-based compensation expenses of $2.9 million (as
restated), and depreciation and amortization expense of $3.6 million (as restated). During the six months ended June 30, 2006, net cash used in operating activities was primarily a result of our net loss of $12.0 million (as restated), changes
in our operating assets and liabilities of $1.7 million (as restated), an increase in accrued investment income of $286,000, and a reduction in our bad debt reserve balance of $35,000, partially offset by stock-based compensation expenses of $3.0
million (as restated), and depreciation and amortization expense of $3.5 million (as restated).

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
$4.0 million for the six months ended June 30, 2007, a $4.0 million increase from the same period in 2006. During the six months ended June 30, 2007, net cash provided by investing activities was primarily the result of proceeds from
maturities and sales of available-for-sale short-term investments of $62.2 million, and changes in our other long-term assets of $43,000, partially offset by purchases of available-for-sale short-term investments of $55.1 million, and capital
expenditures of $3.1 million. During the six months ended June 30, 2006, net cash provided by investing activities was primarily the result of proceeds from maturities and sales of available-for-sale short-term investments of $37.4 million, and
changes in our other long-term assets of $22,000, partially offset by purchases of available-for-sale short-term investments of $34.5 million, and capital expenditures of $2.9 million.

Cash flows from financing activities (as restated). 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. Net cash provided by financing activities was $1.1 million (as restated) for the six months ended June 30, 2007, a $4.5 million (as restated)
increase over the same period in 2006. During the six month period ended June 30, 2007, net cash provided by financing activities was attributable to proceeds of $3.2 million from issuance of common stock as a result of options exercised
by our employees, partially offset by $842,000 of repurchases of common stock from our employees for payment of income and other payroll taxes they owed upon the vesting of share awards and upon the exercise of stock options, and $1.3 million
in principal payments of lease financing obligations. During the six month period ended June 30, 2006, net cash used in financing activities was attributable to $2.5 million of open-market purchases of our common stock under our stock
repurchase program and $1.1 million (as restated) in principal payments of lease financing obligations, partially offset by $191,000 of proceeds from issuance of common stock as a result of options exercised by our employees.

We use well-regarded investment management firms to manage our invested cash. Our portfolio of investments managed by these investment managers is
primarily composed of highly rated United States corporate obligations, United States government securities, and to a lesser extent, foreign corporate obligations, certificates of deposit, 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 expect that cash
requirements for our payroll and other operating costs will continue at or slightly above 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. Furthermore, our cash reserves may be used to strategically acquire other companies, products, or technologies that are complementary to our business.

Our existing cash, cash equivalents, and investment balances will likely decline during 2007 as a result
of our anticipated operating losses. In addition, any weakening of current economic conditions, or changes in our planned cash outlay, could also negatively affect our existing cash, cash equivalents, and investment balances. However, based on our
current business plan and revenue prospects, we believe that our existing cash and short-term investment balances will be sufficient to meet our projected working capital and other cash requirements for at least the next twelve months. Cash from
operations could be affected by various risks and uncertainties, including, but not limited to, the risks detailed later in this discussion in the section titled Factors That May Affect Future Results of Operations. In the
unlikely event that we would require additional financing within this period, such financing may not be available to us in the amounts or at the times that we require, or on acceptable terms. If we fail to obtain additional financing, when and if
necessary, our business would be harmed.

RELATED PARTY TRANSACTIONS

During the quarter and six months ended June 30, 2007, and the years ended December 31, 2006, 2005, and 2004, the law firm of Wilson Sonsini
Goodrich & Rosati, P.C. acted 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, M. Kenneth Oshman, our Chairman of the Board and Chief Executive Officer, uses private air travel services for business trips for
himself and for any employees accompanying him. Prior to January 1, 2005, a company controlled by Armas Clifford Markkula, a director of our company, provided these private air travel services. Our net expense with respect to such private air
travel services is no greater than comparable first class commercial air travel services. Such net outlays to date have not been material.

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 (see Note 13 to our accompanying condensed consolidated
financial statements for additional information on our transactions with Enel). 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. As of July 31, 2007, a
representative of Enel has not been appointed to 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 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 will purchase additional electronic components and finished goods from Echelon, assuming certain initial acceptance tests are completed successfully. Under the software enhancement agreement, we will
provide software enhancements to Enel for use in its Contatore Elettronico system. Both the new development and supply agreement and the software enhancement agreement expire in December 2009, although delivery of products and services can extend
beyond that date and the agreements may be extended under certain circumstances.

For the quarter and six months ended June 30, 2007,
we recognized revenue from products and services sold to Enel and its designated manufacturers of approximately $3.8 million and $5.0 million, respectively. As of June 30, 2007, $158,000 of our total accounts receivable balance related to
amounts owed by Enel and its designated manufacturers. For the quarter and six months ended June 30, 2006, we recognized revenue from products and services sold to Enel and its designated manufacturers of approximately $6.9 million and $7.1
million, respectively. As of June 30, 2006, $6.8 million of our total accounts receivable balance related to amounts owed by Enel and its designated manufacturers.

RECENTLY ISSUED ACCOUNTING STANDARDS

In February 2007, the FASB issued Statement of Financial Accounting Standards No. 159 (SFAS 159), The Fair Value
Option for Financial Assets and Financial Liabilities. SFAS 159 permits companies to choose to measure certain financial instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which
the fair value option has been elected be reported in earnings. SFAS 159 is effective for Echelon beginning in our fiscal year ending December 31, 2008, although earlier adoption is permitted. We are currently evaluating the impact that SFAS
159 will have on our consolidated financial statements.

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.

Our NES revenues may not be predictable.

We and our
partners sell our NES system to utilities. For several reasons sales cycles with utility companies are generally 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 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. 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:



| |  |  | 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 NES system field trials.
| | - |  | ---------------------------------------------------------------------------------------

Once a utility decides to move forward with a large-scale deployment of 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 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 or all of the revenue associated with NES product shipments until certain conditions are met in a future period. As a consequence, 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 and our investors will have increasing difficulty in projecting our financial results.

Sales of our NES system may fail to meet our financial targets.

We have invested and intend to continue to invest significant resources in the development and sales of our NES system. 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 yielded very little gross profit, while our NES related operating expenses have increased significantly. Additionally, gross margins on our NES system offerings are
currently lower than gross margins on our other product offerings.

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 revenues;
| | - |  | ------------------------------------------------------------------------------------



41



---

##### Table of Contents

| |  |  | Increase gross margin from our NES revenues by reducing the cost of manufacturing our NES system products;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | 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.

We depend on a limited number of key suppliers.

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 WKK Technology, TYCO TEPC/Transpower, and Flextronics. 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, and finished products, and manufacturing yields. In addition, CEMs can experience turnover and instability, 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, which is an important component that we and our customers use in control network devices, is currently manufactured and distributed by two
providers, Toshiba and Cypress Semiconductor. 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 cannot be certain that these and other key suppliers will continue to supply us with critical products or components. 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. In addition, 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 and in-process inventory between locations 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 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.

We may incur penalties and/or be liable for damages with respect to sales of our NES system products.

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 will expose us to penalties, damages and other liabilities. Even in the absence of such contractual provisions, we
may agree 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.

Our products use components or materials that may be subject to price fluctuations, shortages, or interruptions of
supply.

We may be vulnerable to price increases for products, components, or materials, such as copper and cobalt. 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.

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.

The
markets for our products are highly competitive.

Competition in our markets is intense and involves rapidly changing technologies,
evolving industry standards, frequent new product introductions, and rapid changes in customer 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 requirements and to develop new or improved products that 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 customer service and support;
| | - |  | ---------------------------------



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



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

Competitors for our NES system products include the Bayard Capital group of companies, DCSI, Elster, General Electric, Iskraemeco, Itron/Actaris, Kamstrup, Sensus, and Siemens, 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 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 150 member companies with promoter members such as Eaton, Freescale, Motorola, Texas
Instruments, STMicroelectronics, Ember, Siemens, Honeywell, Mitsubishi Electric, Samsung, Schneider Electric, Tendril, Huawei Technologies, and Philips.

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

##### Table of Contents

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. 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.

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
undetected errors or failures when first introduced, as new versions are released, or as a result of the manufacturing process. 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.

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.

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. In certain very limited instances, these agreements require that we be named as
an additional insured on our customers insurance policies. However, our customer contracts and additional insured coverage 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.

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 our company. 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 various 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.

We face financial and operational risks associated with international operations.

We have operations located in nine countries around the world. Revenues from international sales, which include both export sales and sales by
international subsidiaries, accounted for about 81.2% of our total net revenues for the quarter ended June 30, 2007, and 75.9% for the same period in 2006, and 86.0% of our total net revenues for the six months ended June 30, 2007, and
68.7% for the same period in 2006. We expect that international sales will constitute an even more significant portion of our total net revenues as our NES revenues, which currently result predominantly from international sales, will increase
significantly in 2007 as compared to 2006.

Changes in the value of currencies in which we conduct our business relative to the U.S. dollar
could 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.

With respect to 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, the majority of our products are assembled by CEMs in China, and
to a lesser extent, in the European Union, 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.

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:



| |  |  | costs of 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 and unexpected changes in regulatory requirements, tariffs, and other trade barriers;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 our products;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | international terrorism and anti-American sentiment; and
| | - |  | --------------------------------------------------------



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

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

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 purchase 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.

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

If 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, and undertaking other activities. To date, we do not have any
significant experience with providing these types of services. As a result, if we sold 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.

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 we expect to incur substantial losses again in 2007.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;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | 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, 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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | shipment and payment schedules may be delayed;
| | - |  | ----------------------------------------------



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



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



| |  |  | 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 as required under Statement of Financial Accounting Standard (SFAS) No. 123(revised 2004),Share-Based Payment, will decrease our earnings;

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

| |  |  | results of impairment tests for goodwill and other intangible assets in accordance with SFAS No. 142, Goodwill and Other Intangible Assets, with respect

| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

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 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 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 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 competitors, which would have a material adverse affect on our revenues, results of operations, and financial condition.

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.

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. 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.

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.

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

Our companys 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, our President and Chief Operating Officer, and our technical personnel. Our future success will depend on our ability to attract, integrate, motivate and retain qualified
technical, sales, operations, and managerial personnel, as well as our ability to successfully implement a plan for management succession.

Competition for qualified personnel in our business areas is intense, and we may not be able to continue to attract and retain qualified executive officers and key personnel. 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.

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;
| | - |  | -----------------------------------------------------------------------------



48



---

##### Table of Contents

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



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



| |  |  | our stock has very limited analyst coverage.
| | - |  | --------------------------------------------

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

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.

In addition, 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.

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

As of July 31, 2007, 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 35.4% 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 representative 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.

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 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, 2006.

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 June 30, 2007 and June 30, 2006, 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. 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 June 30, 2007, and June 30, 2006, our financial position and results of
operations would not be materially affected. However, we could experience a material impact in the future.



|ITEM 4. | CONTROLS AND PROCEDURES (As Restated)
|------- | -------------------------------------

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/A, 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 and considering the material weaknesses in internal control over financial reporting described below, our Chief Executive Officer and our Chief Financial
Officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2007.

In the Companys
previously filed Quarterly Report on Form 10-Q for the quarter ended June 30, 2007, we concluded that the Companys disclosure controls and procedures as of June 30, 2007 were effective. However, in April 2008, the Company identified
the following material weaknesses in our internal control over financial reporting, which resulted in the need to restate our previously issued financial statements:



| |  |  | We lacked policies and procedures for the timely review of the amortization settings within our third-party equity compensation software application; these settings
ensure that the automated calculation of stock-based compensation expense uses our selected method of amortization under SFAS 123R; and,
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We lacked effectively designed policies and procedures for the accounting and disclosure of our San Jose, California facilities leases.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



50

##### Table of Contents

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility that a material misstatement of our companys annual or interim financial statements will not be prevented or detected on a timely basis.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rule 13a-15(e) of the Exchange Act) that occurred during the quarter ended June 30, 2007 that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.

Subsequent to March 31, 2008, we have or are planning to take the
following actions to address the material weaknesses in our internal control over financial reporting noted above:



| |  |  | develop reports to show critical inputs within our third-party equity compensation software application;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | implement controls to ensure an appropriate and timely review of all critical input settings within our equity compensation software application;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide additional training for all employees who are users of the equity compensation software application or the information reported by the application; and,
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | design and implement controls to properly account and provide required disclosures for our San Jose, California headquarters facilities leases.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------

In conjunction with the restatement, we reviewed all amortization settings and corrected the settings within our
third-party equity compensation software application to ensure proper amortization of stock-based compensation expense. We have also corrected the accounting for our San Jose, California headquarters facilities leases.

We believe as a result of the actions we have taken in conjunction with the restatement, the information contained in this Form 10-Q/A fairly presents,
in all material respects, our financial condition and results of operations for the periods contained therein.

|ITEM 2. | UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
|------- | -----------------------------------------------------------

In March and August 2004, our board of directors approved a stock repurchase program, which authorizes us to repurchase up to 3.0 million shares of our common stock in the open market, in accordance with Rule 10b-18 and other
applicable laws, rules and regulations. The board of directors extended the term of the stock repurchase program in March 2006 and again in February 2007. Since inception, we have repurchased a total of 2,204,184 shares under the program at a cost
of $16.1 million. As of June 30, 2007, 795,816 shares are available for repurchase. The stock repurchase program will expire in March 2008. The following table provides information about the repurchase of our common stock during the quarter
ended June 30, 2007:
