Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization and Summary of Significant Accounting Policies

(a) Description of Business

Zhone Technologies, Inc. (sometimes referred to, collectively with its subsidiaries, as “Zhone” or the “Company”) designs, develops and manufactures communications network equipment for telecommunications, wireless and cable operators worldwide. The Company’s products allow network service providers to deliver video and interactive entertainment services in addition to their existing voice and data service offerings. The Company was incorporated under the laws of the state of Delaware in June 1999. The Company began operations in September 1999 and is headquartered in Oakland, California.

(b) Basis of Presentation

The condensed consolidated financial statements are unaudited and reflect all adjustments (consisting only of normal recurring adjustments) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All significant inter-company transactions and balances have been eliminated in consolidation. The results of operations for the current interim period are not necessarily indicative of results to be expected for the current year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2011.

(c) Risks and Uncertainties

The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has continued to incur losses in 2011 and the six months ended June 30, 2012. As of June 30, 2012, the Company had approximately $13.1 million in cash and cash equivalents and $10.0 million in current debt outstanding under its revolving line of credit and letter of credit facility (the “WFB Facility”). The Company entered into the new WFB Facility on March 13, 2012 to replace its former revolving line of credit and letter of credit facility and provide liquidity and working capital through March 12, 2014, as discussed in Note 7.

The global unfavorable economic and market conditions could impact the Company’s business in a number of ways, including:

• Potential deferment of purchases and orders by customers;

• Customers’ inability to obtain financing to make purchases from the Company and/or maintain their business;

• Negative impact from increased financial pressures on third-party dealers, distributors and retailers; and

• Negative impact from increased financial pressures on key suppliers.

If the economic, market and geopolitical conditions in the United States and the rest of the world do not continue to improve or if they deteriorate, the Company may experience material adverse impacts on its business, operating results and financial condition.

The Company expects that its operating losses may continue. In order to meet the Company’s liquidity needs and finance its capital expenditures and working capital needs for the business, the Company may be required to sell assets, issue debt or equity securities or borrow on unfavorable terms. Continued uncertainty in credit markets may negatively impact the Company’s ability to access debt financing or to refinance existing indebtedness in the future on favorable terms, or at all. The Company may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. As a result, the Company may become unable to pay its ordinary expenses, including its debt service, on a timely basis. The Company’s current lack of liquidity could harm it by:

• increasing its vulnerability to adverse economic conditions in its industry or the economy in general;

• requiring substantial amounts of cash to be used for debt servicing, rather than other purposes, including operations;

• limiting its ability to plan for, or react to, changes in its business and industry; and

6

• influencing investor and customer perceptions about its financial stability and limiting its ability to obtain financing or acquire customers.

If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict the Company’s ability to operate its business. Likewise, any equity financing could result in additional dilution of the Company’s stockholders. If the Company is unable to obtain additional capital or is required to obtain additional capital on terms that are not favorable, it may be required to reduce the scope of its planned product development and sales and marketing efforts beyond the reductions it has previously taken. Based on the Company’s current plans and business conditions, it believes that its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for the next twelve months.

(d) Use of Estimates

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

(e) Revenue Recognition

The Company recognizes revenue when the earnings process is complete. The Company recognizes product revenue upon shipment of product under contractual terms which transfer title to customers upon shipment, under normal credit terms, net of estimated sales returns and allowances at the time of shipment. The Company’s arrangements generally do not have any significant post-delivery obligations. If the Company’s arrangements include customer acceptance provisions, revenue is recognized upon obtaining the signed acceptance certificate from the customer, unless the Company can objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement prior to obtaining the signed acceptance. In those instances where revenue is recognized prior to obtaining the signed acceptance certificate, the Company uses successful completion of customer testing as the basis to objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement. The Company also considers historical acceptance experience with the customer, as well as the payment terms specified in the arrangement, when revenue is recognized prior to obtaining the signed acceptance certificate. When collectability is not reasonably assured, revenue is recognized when cash is collected.

The Company makes certain sales to product distributors. These customers are given certain privileges to return a portion of inventory. Return privileges generally allow distributors to return inventory based on a percent of purchases made within a specific period of time. The Company recognizes revenue on sales to distributors that have contractual return rights when the products have been sold by the distributors, unless there is sufficient customer specific sales and sales returns history to support revenue recognition upon shipment. In those instances when revenue is recognized upon shipment to distributors, the Company uses historical rates of return from the distributors to provide for estimated product returns. The Company accrues for warranty costs, sales returns and other allowances at the time of shipment based on historical experience and expected future costs.

The Company’s products and services qualify as separate units of accounting and are deemed to be non-contingent deliverables as the Company’s arrangements typically do not have any significant performance, cancellation, termination and refund type provisions. Products are typically considered delivered upon shipment. Revenue from services is recognized ratably over the period during which the services are to be performed.

The Company derives revenue primarily from stand-alone sales of its products. In certain cases, the Company’s products are sold along with services, which include education, training, installation, and/or extended warranty services. The Company has established third-party evidence of selling price (“TPE”) for its training, education and installation services. TPE is determined based on competitor prices for similar deliverables when sold separately. These service arrangements are typically short term in nature and are largely completed shortly after delivery of the product. Training and education services are based on a daily rate per person and vary according to the type of class offered. Installation services are based on daily rate per person and vary according to the complexity of the products being installed.

Extended warranty services are priced based on the type of product and are sold in one to five year durations. Extended warranty services include the right to warranty coverage beyond the standard warranty period. In substantially all of the arrangements with multiple deliverables pertaining to arrangements with these services, the Company has used and intends to continue using vendor-specific objective evidence of selling price (“VSOE”) to determine the selling price for the services. The Company determines VSOE based on its normal pricing practices for these specific services when sold separately.

7

In most instances, particularly as it relates to products, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on TPE. Generally, the Company’s marketing strategy differs from that of the Company’s peers and the Company’s offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE for the Company’s products.

When the Company is unable to establish selling price using VSOE or TPE, the Company uses best estimate of selling price (“BSP”). The objective of BSP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The BSP of each deliverable is determined using average discounts from list price from historical sales transactions or cost plus margin approaches based on the factors, including but not limited to, the Company’s gross margin objectives and pricing practices plus customer and market specific considerations.

(f) Fair Value of Financial Instruments

The Company utilizes the market approach to measure fair value of its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

The Company utilizes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

Level 1 -	Inputs are quoted prices in active markets for identical assets or liabilities.
Level 2 -	Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 -	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The following financial instruments are not measured at fair value on the Company’s condensed consolidated balance sheet as of June 30, 2012, but require disclosure of their fair values: cash and cash equivalents and debt. The estimated fair value of such instruments at June 30, 2012 approximated their carrying value as reported on the condensed consolidated balance sheet. The fair value of cash and cash equivalents would be categorized as Level 1 at June 30, 2012 and December 31, 2011. The fair value of the Company’s debt obligations approximates fair value based on Level 2 inputs at June 30, 2012 and December 31, 2011. The fair value of debt is determined using the income approach based on the present value of the estimated cash flows.

The Company had no financial assets and liabilities as of June 30, 2012 recorded at fair value.

(g) Concentration of Risk

The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, Internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts. For the three and six months ended June 30, 2012, Global Village Telecom (“GVT”) accounted for 10% and 12% of net revenue, respectively. For the three and six months ended June 30, 2012, Axtel S.A.B. DE C.V. (“Axtel”) accounted for 11% and 8% of net revenue, respectively. For both the three and six months ended June 30, 2011, GVT accounted for 7% of net revenue. For the three and six months ended June 30, 2011, Axtel accounted for 8% and 6% of net revenue, respectively.

8

As of June 30, 2012, Emirates Telecommunications Corporation (“Etisalat”), GVT and Axtel accounted for 19%, 11% and 13% of net accounts receivable, respectively. As of December 31, 2011, the same customers accounted for 29%, 2% and 24% of net accounts receivable, respectively.

As of June 30, 2012 and December 31, 2011, receivables from customers in countries other than the United States represented 70% and 71%, respectively, of net accounts receivable.

(h) Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives. Useful lives of all property and equipment range from 3 to 5 years. Leasehold improvements are generally amortized over the shorter of their useful lives or the remaining lease term.

(i) Inventories

Inventories are stated at the lower of cost or market, with cost being determined using the first-in, first-out (FIFO) method. In assessing the net realizable value of inventories, the Company is required to make judgments as to future demand requirements and compare these with the current or committed inventory levels. Once inventory has been written down to its estimated net realizable value, its carrying value cannot be increased due to subsequent changes in demand forecasts. To the extent that a severe decline in forecasted demand occurs, or the Company experiences a higher incidence of inventory obsolescence due to rapidly changing technology and customer requirements, the Company may incur significant charges for excess inventory.

(2) Cash and Cash Equivalents

Cash and cash equivalents as of June 30, 2012 and December 31, 2011 consisted of the following (in thousands):

	June 30, 2012		December 31, 2011
Cash and Cash Equivalents:
Cash	$	13,130	$	18,124
Money Market Funds		—		66
	$	13,130	$	18,190

As of June 30, 2012 and December 31, 2011, the fair value equaled cost of the cash and cash equivalents.

(3) Operating Lease Liabilities

As a result of the acquisition of Paradyne Networks, Inc. (“Paradyne”) in September 2005, the Company assumed certain lease liabilities for facilities in Largo, Florida. The Company had accrued a liability for the excess portion of these facilities. The term of the lease expired in June 2012 and accordingly the remaining related obligation was zero at June 30, 2012.

A summary of current period activity related to excess lease liabilities accrued is as follows (in thousands):

	Exit Costs
Balance at December 31, 2011	$	835
Cash payments, net		(835	)
Balance at June 30, 2012	$	—

(4) Inventories

Inventories as of June 30, 2012 and December 31, 2011 were as follows (in thousands):

	June 30, 2012		December 31, 2011
Inventories:
Raw materials	$	16,501	$	16,770
Work in process		2,508		2,985
Finished goods		8,649		7,638

(5) Property and Equipment, net

Property and equipment, net, as of June 30, 2012 and December 31, 2011 were as follows (in thousands):

	June 30, 2012			December 31, 2011
Property and equipment:
Machinery and equipment	$	9,093		$	9,043
Computers and acquired software		4,098			4,076
Furniture and fixtures		310			310
Leasehold improvements		2,067			2,067
		15,568			15,496
Less accumulated depreciation and amortization		(14,984	)		(14,888	)
	$	584		$	608

Depreciation and amortization expense associated with property and equipment amounted to $0.2 million and $0.9 million for the six months ended June 30, 2012 and 2011, respectively.

(6) Net Loss Per Share

Basic net loss per share is computed by dividing the net loss applicable to holders of common stock for the period by the weighted average number of shares of common stock outstanding during the period. The calculation of diluted net loss per share gives effect to common stock equivalents; however, potential common equivalent shares are excluded if their effect is antidilutive. Potential common equivalent shares are composed of incremental shares of common equivalent shares issuable upon the exercise of stock options and warrants.

The following tables set forth potential common stock that is not included in the diluted net loss per share calculation because their effect would be anti-dilutive for the periods indicated (in thousands, except exercise price per share data):

	Three Months Ended June  30, 2012		Weighted Average Exercise Price		Six Months Ended June 30, 2012		Weighted Average Exercise Price
Warrants		7	$	116.54		7	$	116.54
Outstanding stock options and unvested restricted shares		5,820	$	2.01		5,820	$	2.01
		5,827				5,827

	Three Months Ended June 30, 2011		Weighted Average Exercise Price		Six Months Ended June 30, 2011		Weighted Average Exercise Price
Warrants		7	$	116.54		7	$	116.54
Outstanding stock options and unvested restricted shares		5,213	$	2.63		5,213	$	2.63
		5,220				5,220

(7) Debt

Credit Facility

In March 2012, the Company’s former revolving credit and letter of credit facility with Silicon Valley Bank expired, and the Company entered into its new $25.0 million WFB Facility with WFB to provide liquidity and working capital through March 12, 2014.

Under the WFB Facility, the Company has the option of borrowing funds at agreed upon interest rates. The amount that the Company is able to borrow under the WFB Facility varies based on eligible accounts receivable, as defined in the agreement, as long as the aggregate amount outstanding does not exceed $25.0 million less the amount committed as security for various letters of credit, which at June 30, 2012 was $11.4 million. To maintain availability of funds under the WFB Facility, the Company pays a commitment fee on the unused portion. The commitment fee is 0.25% per annum and is recorded as interest expense.

Under the WFB Facility, $10.0 million was outstanding at June 30, 2012. In addition, $11.4 million was committed as security for various letters of credit and the Company had $2.3 million unused availability under the WFB Facility as of June 30, 2012. The amounts borrowed under the WFB Facility bear interest, payable monthly, at a floating rate equal to the three-month LIBOR plus a margin of 3.5%. The interest rate on the WFB Facility was 3.97% at June 30, 2012.

The Company’s obligations under the WFB Facility are secured by substantially all of its personal property assets and those of its subsidiaries that guarantee the WFB Facility, including their intellectual property. The WFB Facility contains certain financial covenants, and customary affirmative covenants and negative covenants. If the Company does not comply with the various covenants and other requirements under the WFB Facility, WFB is entitled to, among other things, require the immediate repayment of all outstanding amounts and sell the Company’s assets to satisfy the obligations under the WFB Facility. As of June 30, 2012, the Company was in compliance with these covenants.

The Company is currently under audit examination by several state taxing authorities for non-income based taxes. The Company has reserved an estimated amount which the Company believes is sufficient to cover potential claims.

Performance Bonds

In the normal course of operations, the Company arranges for the issuance of various types of surety bonds, such as bid and performance bonds, which are agreements under which the surety company guarantees that the Company will perform in accordance with contractual or legal obligations. If the Company fails to perform under its obligations, the maximum potential payment under these surety bonds would have been $7.4 million as of June 30, 2012.

Purchase Commitments

The Company has agreements with various contract manufacturers which include non-cancellable inventory purchase commitments. The Company’s inventory purchase commitments typically allow for cancellation of orders 30 days in advance of the required inventory availability date as set by the Company at time of order. The amount of non-cancellable purchase commitments outstanding was $7.2 million as of June 30, 2012.

Royalties

The Company has certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a dollar amount per unit shipped or a percentage of the underlying revenue and is recorded in cost of revenue.

12

Legal Proceedings

The Company is subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, the Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on its consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.

(9) Enterprise-Wide Information

The Company designs, develops and manufactures communications products for network service providers. The Company derives substantially all of its revenues from the sales of the Zhone product family. The Company’s chief operating decision maker is the Company’s Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis accompanied by disaggregated information about revenues by geographic region for purposes of making operating decisions and assessing financial performance. The Company has determined that it has operated within one discrete reportable business segment since inception. The following tables summarize required disclosures about geographic concentrations and revenue by products and services (in thousands):

(10) Income Taxes

The total amount of unrecognized tax benefits, including interest and penalties, at June 30, 2012 was not material. The amount of tax benefits that would impact the effective rate, if recognized, is not expected to be material. There were no significant changes to unrecognized tax benefits during the quarters ended June 30, 2012 and 2011. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The open tax years for the major jurisdictions are as follows:

•   Federal	2008 – 2011
•   California and Canada	2007 – 2011
•   Brazil	2006 – 2011
•   Germany	2005 – 2011
•   United Kingdom	2007 – 2011

13

However, due to the fact the Company had net operating losses and credits carried forward in most jurisdictions, certain items attributable to technically closed years are still subject to adjustment by the relevant taxing authority through an adjustment to tax attributes carried forward to open years.

In addition, to the extent the Company is deemed to have a sufficient connection to a particular taxing jurisdiction to enable that jurisdiction to tax the Company but the Company has not filed an income tax return in that jurisdiction for the year(s) at issue, the jurisdiction would typically be able to assert a tax liability for such years without limitation on the number of years it may examine.

The Company is not currently under examination for income taxes in any material jurisdiction.

(11) Subsequent Events

On August 7, 2012, the Board of Directors of the Company approved an acceleration program for the vesting of all unvested options to purchase shares of common stock of the Company. The Company’s senior management’s acceleration was effective as of August 9, 2012.

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

Forward-Looking Statements

This report, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” contains forward-looking statements regarding future events and our future results that are subject to the safe harbors created under the Securities Act of 1933 and the Securities Exchange Act of 1934. These statements are based on current expectations, estimates, forecasts, and projections about the industries in which we operate and the beliefs and assumptions of our management. We use words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “project,” “seek,” “should,” “target,” “will,” “would,” variations of such words, and similar expressions to identify forward-looking statements. In addition, statements that refer to projections of earnings, revenue, costs or other financial items; anticipated growth and trends in our business or key markets; future growth and revenues from our Single Line Multi-Service, or SLMS, products; our ability to refinance or repay our existing indebtedness prior to the applicable maturity date; future economic conditions and performance; anticipated performance of products or services; plans, objectives and strategies for future operations; and other characterizations of future events or circumstances, are forward-looking statements. Readers are cautioned that these forward-looking statements are only predictions and are subject to risks, uncertainties and assumptions that are difficult to predict, including those identified under the heading “Risk Factors” in Part II, Item 1A elsewhere in this report and our other filings with the Securities and Exchange Commission (the SEC). Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Factors that might cause such a difference include, but are not limited to, the ability to generate sufficient revenue to achieve or sustain profitability, the ability to raise additional capital to fund existing and future operations or to repay or refinance our existing indebtedness, defects or other performance problems in our products, the economic slowdown in the telecommunications industry that has restricted the ability of our customers to purchase our products, commercial acceptance of our SLMS products, intense competition in the communications equipment market from large equipment companies as well as private companies with products that address the same networks needs as our products, higher than anticipated expenses that we may incur, and other factors identified elsewhere in this report and in our most recent reports on Forms 10-K, 10-Q and 8-K. We undertake no obligation to revise or update any forward-looking statements for any reason.

OVERVIEW

We believe that we are the first company dedicated solely to developing the full spectrum of next-generation access network solutions to cost-effectively deliver high bandwidth services while simultaneously preserving the investment in today’s networks. Our next-generation solutions are based upon our SLMS architecture. From its inception, this SLMS architecture was specifically designed for the delivery of multiple classes of subscriber services (such as voice, data and video distribution), rather than being based on a particular protocol or media. In other words, our SLMS products are built to support the migration from legacy circuit to packet technologies and from copper to fiber technologies. This flexibility and versatility allows our products to adapt to future technologies while allowing service providers to focus on the delivery of additional high bandwidth services. Because this SLMS architecture is designed to interoperate with existing legacy equipment, service providers can leverage their existing networks to deliver a combination of voice, data and video services today, while they migrate, either simultaneously or at a future date, from legacy equipment to next-generation equipment with minimal interruption. We believe that our SLMS solution provides an evolutionary path for service providers from their existing infrastructures, as well as gives newer service providers the capability to deploy cost-effective, multi-service networks that can support voice, data and video.

14

Our global customer base includes regional, national and international telecommunications carriers. To date, our products are deployed by over 750 network service providers on six continents worldwide. We believe that we have assembled the employee base, technological breadth and market presence to provide a simple yet comprehensive set of next-generation solutions to the bandwidth bottleneck in the access network and the other problems encountered by network service providers when delivering communications services to subscribers.

Since inception, we have incurred significant operating losses and had an accumulated deficit of $1,037.6 million as of June 30, 2012, and we expect that our operating losses may continue. If we are unable to access or raise the capital needed to meet liquidity needs and finance capital expenditures and working capital, or if the economic, market and geopolitical conditions in the United States and the rest of the world do not continue to improve or deteriorate, we may experience material adverse impacts on our business, operating results and financial condition.

Going forward, our key financial objectives include the following:

• Increasing revenue while continuing to carefully control costs;

• Continued investments in strategic research and product development activities that will provide the maximum potential return on investment; and

• Minimizing consumption of our cash and short-term investments.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no material changes to our critical accounting policies and estimates from the information provided in Part II, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” included in our Annual Report on Form 10-K for the year ended December 31, 2011.

For the three months ended June 30, 2012, net revenue decreased 2% or $0.5 million to $30.8 million from $31.3 million for the same period last year. For the six months ended June 30, 2012, net revenue decreased 5% or $3.0 million to $57.9 million from $60.9 million for the same period last year.

For the three months ended June 30, 2012, product revenue decreased 2% or $0.7 million to $29.4 million, compared to $30.1 million for the same period last year. For the six months ended June 30, 2012, product revenue decreased 5% or $3.1 million to $55.5 million, compared to $58.6 million for the same period last year.

The decreases in net revenue and product revenue for the three months ended June 30, 2012 were primarily due to fewer sales of our products in the Middle East compared to the prior year, which were partially offset by increases in sales of our products to customers in Asia. The decreases in net revenue and product revenue for the six months ended June 30, 2012 were primarily due to fewer sales of our products in the Middle East and the United States (including a reduction in sales to Emirates Telecommunications Corporation (Etisalat)) compared to the prior year, which were partially offset by increases in sales of our products to customers in Latin America and Asia.

For the three months ended June 30, 2012, service revenue increased 17% or $0.2 million to $1.4 million from $1.2 for the same period last year. For the six months ended June 30, 2012, service revenue increased by 4% or $0.1 million to $2.4 million, compared to $2.3 million for the same period last year. Service revenue represents revenue from maintenance and other services associated with product shipments.

International net revenue decreased 4% or $0.8 million to $17.5 million for the three months ended June 30, 2012 from $18.3 million for the same period last year, and represented 57% of total net revenue compared with 58% during the same period of 2011. For the six months ended June 30, 2012, international revenue decreased 5% or $1.6 million to $32.9 million from $34.5 million for the same period last year, and represented 57% of total revenue for both periods. The decreases in international net revenue during the three and six months ended June 30, 2012 were primarily due to decreases in sales as compared with the same periods last year in the Middle East, which were only partially offset by increases in sales to customers in Asia.

For the three and six months ended June 30, 2012, Global Village Telecom (GVT) represented 10% and 12% of net revenue, respectively, and represented 7% of net revenue for the same periods in 2011. For the three and six months ended June 30, 2012, Axtel S.A.B. DE C.V. (Axtel) represented 11% and 8% of net revenue, respectively, and represented 8% and 6% of net revenue, respectively, for the same periods in 2011. We anticipate that our results of operations in any given period may depend to a large extent on sales to a small number of large accounts. As a result, our revenue for any quarter may be subject to significant volatility based upon changes in orders from one or a small number of key customers.

Cost of Revenue and Gross Profit

Total cost of revenue, including stock-based compensation, increased 7% or $1.3 million to $21.6 million for the three months ended June 30, 2012, compared to $20.2 million for the three months ended June 30, 2011. Cost of revenue increased $1.0 million or 3% to $40.2 million for the six months ended June 30, 2012 compared to $39.2 million for the same period last year. The increase in cost of revenue for the three and six months ended June 30, 2012 was primarily due to changes in product mix. Gross margin decreased for both the three and six months ended June 30, 2012 as compared with the same periods last year due to greater sales of products with lower gross margin, such as our GPON products. Total cost of revenue was 70% and 65% of net revenue for the three months ended June 30, 2012 and 2011, respectively, and 70% and 64% of net revenue for the six months ended June 30, 2012 and 2011, respectively.

We expect that in the future our cost of revenue as a percentage of net revenue will vary depending on the mix and average selling prices of products sold. In addition, continued competitive and economic pressures could cause us to reduce our prices, adjust the carrying values of our inventory, or record inventory charges relating to discontinued products and excess or obsolete inventory.

Research and Product Development Expenses

Research and product development expenses decreased 12% or $0.6 million to $4.8 million for the three months ended June 30, 2012, compared to $5.4 million for the three months ended June 30, 2011, and decreased 11% or $1.2 million to $9.7 million from $11.0 million for the six months ended June 30, 2012 compared to the six months ended June 30, 2011. The decrease in the three and six months ended June 30, 2012 was primarily due to decreased depreciation expense as a result of the fixed asset impairment and decreases in allocated facility costs.

Sales and Marketing Expenses

Sales and marketing expenses decreased 11% or $0.6 million to $4.8 million for the three months ended June 30, 2012, compared to $5.4 million for the three months ended June 30, 2011, and decreased 12% or $1.4 million to $9.5 million from $10.9 million for the six months ended June 30, 2012 compared to the six months ended June 30, 2011. The decrease for the three months ended June 30, 2012 was primarily due to a $0.4 million decrease in sales expenses from continued cost reductions in travel and consulting expenses, and decreased commissions, as well as a decrease in customer service related personnel expenses of $0.1 million. The decrease for the six months ended June 30, 2012 was primarily due to decreases in sales expense of $0.8 million from continued cost reductions in personnel and consulting expenses, and decreased commissions, as well as a decrease of $0.3 million in marketing expenses.

General and Administrative Expenses

General and administrative expenses decreased 18% or $0.4 million to $1.7 million from $2.1 million for the three months ended June 30, 2012 compared to the three months ended June 30, 2011, and decreased 8% or $0.4 million to $3.8 million from $4.2 million for the six months ended June 30, 2012 compared to the six months ended June 30, 2011. The decrease for the three and six months ended June 30, 2012 was primarily due to $0.5 million gain as a result of patent sales.

Income Tax Provision

During the three and six months ended June 30, 2012 and 2011, no material provision or benefit for income taxes was recorded, due to our recurring operating losses and the significant uncertainty regarding the realization of our net deferred tax assets, against which we have continued to record a full valuation allowance.

OTHER PERFORMANCE MEASURES

In managing our business and assessing our financial performance, we supplement the information provided by our GAAP results with adjusted earnings before stock-based compensation, interest, taxes, and depreciation, or Adjusted EBITDA, a non-GAAP financial measure. We define Adjusted EBITDA as net income (loss) plus (i) interest expense, (ii) provision (benefit) for taxes, (iii) depreciation and amortization, (iv) non-cash equity-based compensation expense, and (v) material non-recurring non-cash transactions. We believe that the presentation of Adjusted EBITDA enhances the usefulness of our financial information by presenting a measure that management uses internally to monitor and evaluate our operating performance and to evaluate the effectiveness of our business strategies. We believe Adjusted EBITDA also assists investors and analysts in comparing our performance across reporting periods on a consistent basis because it excludes the impact of items that we do not believe reflect our core operating performance.

17

Adjusted EBITDA has limitations as an analytical tool. Some of these limitations are:

• Adjusted EBITDA does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual requirements;

• Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

• Adjusted EBITDA does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debts;

• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

• non-cash compensation is and will remain a key element of our overall long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period; and

• other companies in our industry may calculate Adjusted EBITDA and similar measures differently than we do, limiting its usefulness as a comparative measure.

Because of these limitations, Adjusted EBITDA should not be considered in isolation or as a substitute for net income (loss) or any other performance measures calculated in accordance with GAAP or as a measure of liquidity. Management understands these limitations and compensates for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only supplementally.

Set forth below is a reconciliation of net income (loss) to Adjusted EBITDA, which we consider to be the most directly comparable GAAP financial measure to Adjusted EBITDA (in thousands):

Adjusted EBITDA	$	(1,734	)	$	(1,126	)	$	(4,851	)	$	(2,886	)

LIQUIDITY AND CAPITAL RESOURCES

Our operations are financed through a combination of our existing cash, cash equivalents, available credit facilities, and sales of equity and debt instruments, based on our operating requirements and market conditions.

At June 30, 2012, cash and cash equivalents were $13.1 million compared to $18.2 million at December 31, 2011. The $5.1 million decrease in cash and cash equivalents was attributable to net cash used in financing and investing activities of $4.9 million and $0.1 million, respectively.

Operating Activities

Net cash used in operating activities for the six months ended June 30, 2012 was immaterial and consisted of a net loss of $5.5 million, adjusted for non-cash charges totaling $1.4 million and a decrease in net operating assets totaling $4.1 million. The most significant components of the changes in net operating assets were a decrease of $5.4 million in accounts receivable, offset by a decrease of $1.6 million in accrued and other liabilities. The decrease in accounts receivable was primarily the result of significant cash collections from several large customers in the current year period which caused a corresponding decrease in accounts payable as more cash was available to apply to vendor invoices. The decrease in accrued and other liabilities was comprised of the decrease in the operating lease liability related to our Largo facility of $0.8 million and reduced personnel accruals of $0.3 million.

Net cash used in operating activities for the six months ended June 30, 2011 was $1.1 million and consisted of a net loss of $4.3 million, adjusted for non-cash charges totaling $2.4 million and a decrease in operating assets totaling $0.8 million. The changes in net operating assets consisted of decreases of $1.8 million in accounts payable and $2.6 million in accrued and other liabilities, and offsetting decreases in inventories and accounts receivable of $3.4 million and $1.9 million, respectively. The decrease in accounts payable related primarily to the timing of vendor payments as well as a $0.7 million decrease due to our determination that certain liabilities had exceeded the applicable statute of limitations. The decrease in accrued and other liabilities was comprised of reduced personnel accruals of $0.6 million, continued reduction of the operating lease liability related to our Largo

18

facility of $0.9 million, a decrease of $0.7 million in unearned revenue, and decreases in the deferred gain and leasehold improvement allowance of $0.4 million from the campus sale-leaseback transaction in the third quarter of 2010 due to continued amortization. The decrease in inventories was primarily due to better utilization of inventory in the current period, and the decrease in accounts receivable was due to significant cash collections in the six months ended June 30, 2011 which were in excess of the additional receivables booked.

Investing Activities

Net cash used in investing activities for the six months ended June 30, 2012 was $0.1 million compared to $0.8 million for the same period last year. Net cash used in investing activities for both periods consisted primarily of purchases of property and equipment.

Financing Activities

Net cash used in financing activities for the six months ended June 30, 2012 was $4.9 million and consisted of repayments of debt of $5.0 million, partially offset by proceeds related to exercises of stock options and purchases under our Employee Stock Purchase Plan of $0.1 million. Net cash provided by financing activities for the six months ended June 30, 2011 consisted of proceeds related to exercises of stock options of $0.1 million.

Cash Management

Our primary source of liquidity comes from our cash and cash equivalents which totaled $13.1 million at June 30, 2012, and our $25.0 million revolving line of credit and letter of credit facility, or the WFB Facility, with Wells Fargo Bank, or WFB. Our cash and cash equivalents are held in accounts managed by third party financial institutions and consist of invested cash and cash in our operating accounts. At current revenue levels, we anticipate that some portion of our existing cash and cash equivalents will continue to be consumed by operations.

In March 2012, our former revolving line of credit and letter of credit facility with Silicon Valley Bank expired, and we entered into our new $25.0 million WFB Facility to provide liquidity and working capital through March 12, 2014.

Under the WFB Facility, we have the option of borrowing funds at agreed upon interest rates. The amount that we are able to borrow under the WFB Facility varies based on eligible accounts receivable, as defined in the agreement, as long as the aggregate principal amount outstanding does not exceed $25.0 million less the amount committed as security for various letters of credit, which at June 30, 2012 was $11.4 million. To maintain availability of funds under the WFB Facility, we pay a commitment fee on the unused portion. The commitment fee is 0.25% per annum and is recorded as interest expense.

Under the WFB Facility, $10.0 million was outstanding at June 30, 2012. In addition, $11.4 million was committed as security under various letters of credit and we had $2.3 million unused availability under the WFB Facility as of June 30, 2012. The amounts borrowed under the WFB Facility bear interest, payable monthly, at a floating rate equal to the three-month LIBOR plus a margin of 3.5%. The interest rate on our WFB Facility was 3.97% at June 30, 2012.

Our obligations under the WFB Facility are secured by substantially all of our personal property assets and those of our subsidiaries that guarantee the WFB Facility, including our intellectual property. The WFB Facility contains certain financial covenants, and customary affirmative covenants and negative covenants. If we do not comply with the various covenants and other requirements under the WFB Facility, WFB is entitled to, among other things, require the immediate repayment of all outstanding amounts and sell our assets to satisfy the obligations under the WFB Facility. As of June 30, 2012, we were in compliance with these covenants. We make no assurances that we will be in compliance with these covenants in the future.

Future Requirements and Funding Sources

Our fixed commitments for cash expenditures consist primarily of payments under operating leases, inventory purchase commitments, and payments of principal and interest for debt obligations. Our operating lease commitments include $2.1 million of future minimum lease payments spread over the five-year lease term under the lease agreement we entered into in September 2010 with respect to our Oakland, California campus following the sale of our campus in a sale-leaseback transaction.

Our accounts receivable, while not considered a primary source of liquidity, represent a concentration of credit risk because a significant portion of the accounts receivable balance at any point in time typically consists of a relatively small number of customer account balances. As of June 30, 2012, Axtel and GVT accounted for 13% and 11% of net accounts receivable, respectively, and receivables from customers in countries other than the United States of America represented 70% of net accounts receivable. We do not currently have any material commitments for capital expenditures, or any other material commitments aside from operating leases for our facilities, inventory purchase commitments and debt.

We expect that operating losses and negative cash flows from operations may continue. In order to meet our liquidity needs and finance our capital expenditures and working capital needs for our business, we may be required to sell assets, issue debt or equity securities or borrow on unfavorable terms. Continued uncertainty in credit markets may

19

negatively impact our ability to access debt financing or to refinance existing indebtedness in the future on favorable terms, or at all. We may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict our ability to operate our business. Likewise, any equity financing could result in additional dilution of our stockholders. If we are unable to obtain additional capital or are required to obtain additional capital on terms that are not favorable to us, we may be required to reduce the scope of our planned product development and sales and marketing efforts beyond the reductions we have previously taken. Based on our current plans and business conditions, we believe that our existing cash, cash equivalents and available credit facilities will be sufficient to satisfy our anticipated cash requirements for the next twelve months.

Contractual Commitments and Off-Balance Sheet Arrangements

At June 30, 2012, our future contractual commitments by fiscal year were as follows (in thousands):

			Payments due by period
	Total		2012		2013		2014		2015		2016 and Thereafter
Operating leases	$	3,316	$	888	$	1,206	$	736	$	486	$	—
Purchase commitments		7,233		7,233		—		—		—		—
Line of credit (1)		10,000		10,000		—		—		—		—
Total future contractual commitments	$	20,549	$	18,121	$	1,206	$	736	$	486	$	—

(1) The specified payment period reflects our current intent to repay all outstanding borrowings within the current year. However, the maturity date under the WFB Facility is March 12, 2014.

Operating Leases

The operating lease amounts shown above represent primarily off-balance sheet arrangements. For operating lease commitments, a liability is generally not recorded on our balance sheet unless the facility represents an excess facility for which an estimate of the facility exit costs has been recorded on our balance sheet, net of estimated sublease income. For operating leases that include contractual commitments for operating expenses and maintenance, estimates of such amounts are included based on current rates. Payments made under operating leases will be treated as rent expense for the facilities currently being utilized.

Purchase Commitments

The purchase commitments shown above represent non-cancellable inventory purchase commitments as of June 30, 2012. The inventory purchase commitments typically allow for cancellation of orders 30 days in advance of the required inventory availability date as set by us at time of order.

Line of Credit

The line of credit obligation has been recorded as a liability on our balance sheet. The line of credit obligation amount shown above represents the scheduled principal repayment, but not the associated interest payments which may vary based on changes in market interest rates. At June 30, 2012, the interest rate under the WFB Facility was 3.97%.

As of June 30, 2012, we had $10.0 million outstanding under our line of credit under the WFB Facility and an additional $11.4 million committed as security for various letters of credit. See above under “Cash Management” for further information about the WFB Facility.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Cash and Cash Equivalents

Cash and cash equivalents consisted of the following as of June 30, 2012 and December 31, 2011 (in thousands):

	June 30, 2012		December 31, 2011
Cash	$	13,130	$	18,124
Money Market Funds		—		66
	$	13,130	$	18,190

20

Concentration of Credit Risk

Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, and accounts receivable. Cash and cash equivalents consist principally of demand deposit and money market accounts. Cash and cash equivalents are principally held with various domestic financial institutions with high credit standing. We perform ongoing credit evaluations of our customers and generally do not require collateral. Allowances are maintained for potential doubtful accounts. For the three months ended June 30, 2012, GVT and Axtel accounted for 10% and 11% of net revenue compared to 7% and 8% of net revenue for the same period last year, respectively. For the six months ended June 30, 2012, GVT and Axtel accounted for 12% and 8% of net revenue compared to 7% and 6% of net revenue for the same period last year, respectively.

As of June 30, 2012, Etisalat, GVT and Axtel accounted for 19%, 11% and 13% of net accounts receivable, respectively. As of December 31, 2011, the same customers accounted for 29%, 2% and 24% of net accounts receivable, respectively.

As of June 30, 2012 and December 31, 2011, receivables from customers in countries other than the United States represented 70% and 71%, respectively, of net accounts receivable.

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to our outstanding debt. As of June 30, 2012, our outstanding debt balance under our WFB Facility was $10.0 million. Interest on the line of credit under our WFB Facility accrues at a floating rate equal to the three-month LIBOR plus a margin of 3.5%. The interest rate on our WFB Facility was 3.97% as of June 30, 2012. Assuming the outstanding balance on our variable rate debt remains constant over a year, a 2% increase in the interest rate would decrease pre-tax income and cash flow by approximately $0.2 million.

Foreign Currency Exchange Risk

We transact business in various foreign countries. Substantially all of our assets are located in the United States. We have sales operations throughout Europe, Asia, the Middle East and Latin America. We are exposed to foreign currency exchange risk associated with foreign currency denominated assets and liabilities, primarily inter-company receivables and payables. Accordingly, our operating results are exposed to changes in exchange rates between the U.S. dollar and those currencies. During 2012 and 2011, we did not hedge any of our foreign currency exposure.

We have performed sensitivity analyses as of June 30, 2012 using a modeling technique that measures the impact arising from a hypothetical 10% adverse movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The sensitivity analyses indicated that a hypothetical 10% adverse movement in foreign currency exchange rates would result in a foreign exchange loss of $0.3 million at June 30, 2012. This sensitivity analysis assumes a parallel adverse shift in foreign currency exchange rates, which do not always move in the same direction. Actual results may differ materially.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. The controls evaluation was done under the supervision and with the participation of management, including our Chief Executive Officer and our Chief Financial Officer. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, subject to the limitations noted in this Part I, Item 4, as of the end of the period covered by this report, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified by the SEC, and that material information relating to Zhone and its consolidated subsidiaries is made known to management, including our Chief Executive Officer and Chief Financial Officer, particularly during the period when our periodic reports are being prepared.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute,

21

assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011, which could materially affect our business, financial condition or future results. There have been no material changes to the risk factors described in the “Risk Factors” section in our Annual Report on Form 10-K for the year ended December 31, 2011, other than the risk factor entitled “Our common stock may be delisted from The Nasdaq Capital Market, which could negatively impact the price of our common stock and our ability to access the capital markets,” which has been added to reflect our receipt of a letter regarding our non-compliance with the minimum per share bid price rule. The risks described in our Annual Report on Form 10-K are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Our common stock may be delisted from The Nasdaq Capital Market, which could negatively impact the price of our common stock and our ability to access the capital markets.

Our common stock is listed on The Nasdaq Capital Market. On June 21, 2012, we received a letter from The Nasdaq Stock Market, or Nasdaq, indicating that, for the last 30 consecutive business days preceding the date of the letter, the bid price of our common stock had closed below the $1.00 minimum per share bid price required for continued inclusion on The Nasdaq Capital Market under Marketplace Rule 5550(a)(2). In accordance with Marketplace Rule 5810(c)3)(A), we were given 180 calendar days from the date of the Nasdaq letter, or until December 18, 2012, to regain compliance with the minimum bid price rule. Our stock price has not closed above $1.00 since the date of the receipt of this letter from Nasdaq. To regain compliance, the closing bid price of our common stock must be at or above $1.00 per share for a minimum of 10 consecutive business days. Nasdaq may, in its discretion, require us to maintain a bid price of at least $1.00 per share for a period in excess of 10 consecutive business days, but generally no more than 20 consecutive business days, before determining that we have demonstrated an ability to maintain long-term compliance. If we do not regain compliance by December 18, 2012, Nasdaq will provide written notification to us that our common stock will be delisted. At that time, we may be eligible for additional time. To qualify, we will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and will need to provide written notice of our intention to cure the deficiency during the second compliance period by effecting a reverse split, if necessary. If we elect to apply for the extension and the requirements are met, we will be granted an additional 180 calendar days. Alternatively, if the Nasdaq staff determines that we will not be able to cure the deficiency, or if we are otherwise not eligible, Nasdaq will provide notice that our common stock will be subject to delisting. We would then have the right to appeal the delisting determination to a Nasdaq Hearings Panel. We are currently actively monitoring the bid price for our common stock, and will consider available options to resolve the deficiency and regain compliance with the Nasdaq minimum bid price requirement.

22

Delisting from The Nasdaq Capital Market could have an adverse effect on our business and on the trading of our common stock. If a delisting of our common stock were to occur, our common stock would trade on the OTC Bulletin Board or on the “pink sheets” maintained by the National Quotation Bureau, Inc. Such alternatives are generally considered to be less efficient markets, and our stock price, as well as the liquidity of our common stock, may be adversely impacted as a result. Delisting from The Nasdaq Capital Market could also have other negative results, including the potential loss of confidence by suppliers and employees, the loss of institutional investor interest and fewer business development opportunities.

Item 5. Other Information

Change of Control Agreements

On August 9, 2012, we entered into change in control severance agreements (the Change in Control Agreements) with the following officers of Zhone: Kirk Misaka, Chief Financial Officer, Treasurer and Secretary, and David Misunas, Vice President, Business Development.

Pursuant to the Change in Control Agreements, in the event that (1) an individual is terminated without “Cause” (as defined in Zhone’s 2001 Stock Incentive Plan, as amended) or (2) following the occurrence of a Change in Control (as defined in Zhone’s 2001 Stock Incentive Plan, as amended), an individual resigns for “Good Reason” (as defined below), we will pay to such individual an amount equal to the greater of (x) the individual’s 2008 annual base salary, prior to giving effect to any voluntary salary reduction, or (y) the individual’s then-current base salary at the time of termination, payable in a lump sum. An individual will be required to sign a general release of claims in to receive the severance payment.

For purposes of the Change in Control Agreements, “Good Reason” means (1) a diminution in an individual’s authority, duties or responsibilities from those in effect immediately prior to the Change in Control, including an adverse change in the individual’s reporting relationship or a change in the named individual to whom such individual reports, (2) a reduction of an individual’s total compensation opportunities, (3) a diminution in the authority, duties or responsibilities of the named individual to whom an individual reports, including a requirement that such individual report to someone other than the Chief Executive Officer of Zhone or someone who reports directly to the Board of Directors of Zhone, or (4) a requirement that an individual relocate his or her principal place of employment by more than 50 miles. An individual must provide notice to us of the existence of one or more of the conditions listed above, within a period not to exceed 90 days of the initial existence of such condition, and we will have a period of 10 days to remedy the condition.

The foregoing description of the Change in Control Agreements is qualified in its entirety by reference to the form of Change in Control Agreement, filed as Exhibit 10.1 hereto, and incorporated herein by reference.

Senior Management Stock Option Acceleration

On August 7, 2012, Zhone’s Board of Directors approved the acceleration of vesting of all unvested options to purchase shares of Zhone common stock that were held by our senior management as of that date. The acceleration was as of August 9, 2012. Options to purchase an aggregate of approximately 308,000 shares of common stock were accelerated. The acceleration of these options was undertaken to partially offset previous reductions in cash compensation and other benefits by our senior management.

The following table summarizes the outstanding options subject to accelerated vesting held by our Chief Executive Officer, Chief Financial Officer and three other most highly compensated senior managers:

Name	Number of Shares Underlying Options Subject to Acceleration		Average Exercise Price ($)
Morteza Ejabat		154,174		1.51

Exhibit 10.1

[Date]

[Name and Address]

Dear [Name of Employee]:

This letter is to confirm our discussion regarding the separation or severance benefits to be provided to you.

In the event that (1) Zhone terminates your employment without “Cause” or (2) following a “Change in Control” you terminate your employment for “Good Reason” (as such terms are defined below), then Zhone will pay you the greater of (i) $            ¹ or (ii) your then current annual salary in a lump sum as severance in exchange for a standard release of claims. You will not receive the severance if you do not sign the release of claims within 50 days following your termination, or you revoke the release. The severance will be paid on the 8^th day following the effective date of the release. You also will not be eligible for the severance payment if you voluntarily terminate your employment prior to a Change in Control for any reason, or following a Change in Control other than for Good Reason, or you are terminated for Cause.

For this purpose, “Cause” and “Change in Control” shall have the respective meanings set forth in the company’s 2001 Stock Incentive Plan, as amended. “Good Reason” shall mean (i) a diminution in your authority, duties or responsibilities from those in effect immediately prior to the Change in Control, including an adverse change in your reporting relationship or a change in the named individual to whom you report, (ii) a reduction of your total compensation opportunities, (iii) a diminution in the authority, duties or responsibilities of the named individual to whom you report, including a requirement that you report to someone other than the Chief Executive Officer of Zhone or someone who reports directly to the Board of Directors of Zhone, or (iv) a requirement that you relocate your principal place of employment by more than 50 miles. You must provide notice to Zhone of the existence of one or more of the conditions listed above, within a period not to exceed 90 days of the initial existence of such condition, and Zhone shall have a period of 10 days to remedy the condition. If Zhone is unable to remedy such condition within the 10-day cure period, you may terminate your employment for Good Reason. For purposes of the definition of Good

¹  Amount will be equal to 2008 annual base salary prior to giving effect to any voluntary salary reduction.

Reason, references to Zhone shall include any successor thereto in the Change in Control, or if Zhone or its successor following such Change in Control is a subsidiary, then Zhone shall mean the ultimate parent company.

This letter and the agreements contained herein shall be binding upon and shall by their terms automatically be assigned to any successor in interest to Zhone in a Change in Control, including but not limited to any entity that acquires substantially all of the assets, capital stock or operations of Zhone.

As is our normal practice, your employment with us will remain voluntarily at-will and for no specified period. Of course you are always free to resign at any time, for any reason, or for no reason, as you deem appropriate. We will have a similar right and may conclude our employment relationship with you at any time, with or without Cause.

The terms stated in this letter, the proprietary rights and stock option agreements you previously executed constitute the entire agreements between you and Zhone regarding the terms and conditions of your employment, and they supersede all prior negotiations, representations or agreements between you and Zhone.

I want to thank all of you for your hard work and contributions in making Zhone successful. With your continued commitment, our best days are ahead of us.

Sincerely,

Mory Ejabat

Chief Executive Officer

I AGREE TO AND ACCEPT TERMS AND CONDITIONS SET FORTH IN THIS AGREEMENT.

Organization and Summary of Significant Accounting Policies

(1) Organization and Summary of Significant Accounting Policies

(a) Description of Business

Zhone Technologies, Inc. (sometimes referred to, collectively with its subsidiaries, as “Zhone” or the “Company”) designs, develops and manufactures communications network equipment for telecommunications, wireless and cable operators worldwide. The Company’s products allow network service providers to deliver video and interactive entertainment services in addition to their existing voice and data service offerings. The Company was incorporated under the laws of the state of Delaware in June 1999. The Company began operations in September 1999 and is headquartered in Oakland, California.

(b) Basis of Presentation

The condensed consolidated financial statements are unaudited and reflect all adjustments (consisting only of normal recurring adjustments) that, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All significant inter-company transactions and balances have been eliminated in consolidation. The results of operations for the current interim period are not necessarily indicative of results to be expected for the current year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2011.

(c) Risks and Uncertainties

The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has continued to incur losses in 2011 and the six months ended June 30, 2012. As of June 30, 2012, the Company had approximately $13.1 million in cash and cash equivalents and $10.0 million in current debt outstanding under its revolving line of credit and letter of credit facility (the “WFB Facility”). The Company entered into the new WFB Facility on March 13, 2012 to replace its former revolving line of credit and letter of credit facility and provide liquidity and working capital through March 12, 2014, as discussed in Note 7.

The global unfavorable economic and market conditions could impact the Company’s business in a number of ways, including:

• Potential deferment of purchases and orders by customers;

• Customers’ inability to obtain financing to make purchases from the Company and/or maintain their business;

• Negative impact from increased financial pressures on third-party dealers, distributors and retailers; and

• Negative impact from increased financial pressures on key suppliers.

If the economic, market and geopolitical conditions in the United States and the rest of the world do not continue to improve or if they deteriorate, the Company may experience material adverse impacts on its business, operating results and financial condition.

The Company expects that its operating losses may continue. In order to meet the Company’s liquidity needs and finance its capital expenditures and working capital needs for the business, the Company may be required to sell assets, issue debt or equity securities or borrow on unfavorable terms. Continued uncertainty in credit markets may negatively impact the Company’s ability to access debt financing or to refinance existing indebtedness in the future on favorable terms, or at all. The Company may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. As a result, the Company may become unable to pay its ordinary expenses, including its debt service, on a timely basis. The Company’s current lack of liquidity could harm it by:

• increasing its vulnerability to adverse economic conditions in its industry or the economy in general;

• requiring substantial amounts of cash to be used for debt servicing, rather than other purposes, including operations;

• limiting its ability to plan for, or react to, changes in its business and industry; and

• influencing investor and customer perceptions about its financial stability and limiting its ability to obtain financing or acquire customers.

If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict the Company’s ability to operate its business. Likewise, any equity financing could result in additional dilution of the Company’s stockholders. If the Company is unable to obtain additional capital or is required to obtain additional capital on terms that are not favorable, it may be required to reduce the scope of its planned product development and sales and marketing efforts beyond the reductions it has previously taken. Based on the Company’s current plans and business conditions, it believes that its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for the next twelve months.

(d) Use of Estimates

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

(e) Revenue Recognition

The Company recognizes revenue when the earnings process is complete. The Company recognizes product revenue upon shipment of product under contractual terms which transfer title to customers upon shipment, under normal credit terms, net of estimated sales returns and allowances at the time of shipment. The Company’s arrangements generally do not have any significant post-delivery obligations. If the Company’s arrangements include customer acceptance provisions, revenue is recognized upon obtaining the signed acceptance certificate from the customer, unless the Company can objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement prior to obtaining the signed acceptance. In those instances where revenue is recognized prior to obtaining the signed acceptance certificate, the Company uses successful completion of customer testing as the basis to objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement. The Company also considers historical acceptance experience with the customer, as well as the payment terms specified in the arrangement, when revenue is recognized prior to obtaining the signed acceptance certificate. When collectability is not reasonably assured, revenue is recognized when cash is collected.

The Company makes certain sales to product distributors. These customers are given certain privileges to return a portion of inventory. Return privileges generally allow distributors to return inventory based on a percent of purchases made within a specific period of time. The Company recognizes revenue on sales to distributors that have contractual return rights when the products have been sold by the distributors, unless there is sufficient customer specific sales and sales returns history to support revenue recognition upon shipment. In those instances when revenue is recognized upon shipment to distributors, the Company uses historical rates of return from the distributors to provide for estimated product returns. The Company accrues for warranty costs, sales returns and other allowances at the time of shipment based on historical experience and expected future costs.

The Company’s products and services qualify as separate units of accounting and are deemed to be non-contingent deliverables as the Company’s arrangements typically do not have any significant performance, cancellation, termination and refund type provisions. Products are typically considered delivered upon shipment. Revenue from services is recognized ratably over the period during which the services are to be performed.

The Company derives revenue primarily from stand-alone sales of its products. In certain cases, the Company’s products are sold along with services, which include education, training, installation, and/or extended warranty services. The Company has established third-party evidence of selling price (“TPE”) for its training, education and installation services. TPE is determined based on competitor prices for similar deliverables when sold separately. These service arrangements are typically short term in nature and are largely completed shortly after delivery of the product. Training and education services are based on a daily rate per person and vary according to the type of class offered. Installation services are based on daily rate per person and vary according to the complexity of the products being installed.

Extended warranty services are priced based on the type of product and are sold in one to five year durations. Extended warranty services include the right to warranty coverage beyond the standard warranty period. In substantially all of the arrangements with multiple deliverables pertaining to arrangements with these services, the Company has used and intends to continue using vendor-specific objective evidence of selling price (“VSOE”) to determine the selling price for the services. The Company determines VSOE based on its normal pricing practices for these specific services when sold separately.

In most instances, particularly as it relates to products, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on TPE. Generally, the Company’s marketing strategy differs from that of the Company’s peers and the Company’s offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE for the Company’s products.

When the Company is unable to establish selling price using VSOE or TPE, the Company uses best estimate of selling price (“BSP”). The objective of BSP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The BSP of each deliverable is determined using average discounts from list price from historical sales transactions or cost plus margin approaches based on the factors, including but not limited to, the Company’s gross margin objectives and pricing practices plus customer and market specific considerations.

(f) Fair Value of Financial Instruments

The Company utilizes the market approach to measure fair value of its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

The Company utilizes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

Level 1 -	Inputs are quoted prices in active markets for identical assets or liabilities.
Level 2 -	Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 -	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The following financial instruments are not measured at fair value on the Company’s condensed consolidated balance sheet as of June 30, 2012, but require disclosure of their fair values: cash and cash equivalents and debt. The estimated fair value of such instruments at June 30, 2012 approximated their carrying value as reported on the condensed consolidated balance sheet. The fair value of cash and cash equivalents would be categorized as Level 1 at June 30, 2012 and December 31, 2011. The fair value of the Company’s debt obligations approximates fair value based on Level 2 inputs at June 30, 2012 and December 31, 2011. The fair value of debt is determined using the income approach based on the present value of the estimated cash flows.

The Company had no financial assets and liabilities as of June 30, 2012 recorded at fair value.

(g) Concentration of Risk

The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, Internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts. For the three and six months ended June 30, 2012, Global Village Telecom (“GVT”) accounted for 10% and 12% of net revenue, respectively. For the three and six months ended June 30, 2012, Axtel S.A.B. DE C.V. (“Axtel”) accounted for 11% and 8% of net revenue, respectively. For both the three and six months ended June 30, 2011, GVT accounted for 7% of net revenue. For the three and six months ended June 30, 2011, Axtel accounted for 8% and 6% of net revenue, respectively.

As of June 30, 2012, Emirates Telecommunications Corporation (“Etisalat”), GVT and Axtel accounted for 19%, 11% and 13% of net accounts receivable, respectively. As of December 31, 2011, the same customers accounted for 29%, 2% and 24% of net accounts receivable, respectively.

As of June 30, 2012 and December 31, 2011, receivables from customers in countries other than the United States represented 70% and 71%, respectively, of net accounts receivable.

(h) Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives. Useful lives of all property and equipment range from 3 to 5 years. Leasehold improvements are generally amortized over the shorter of their useful lives or the remaining lease term.

(i) Inventories

Inventories are stated at the lower of cost or market, with cost being determined using the first-in, first-out (FIFO) method. In assessing the net realizable value of inventories, the Company is required to make judgments as to future demand requirements and compare these with the current or committed inventory levels. Once inventory has been written down to its estimated net realizable value, its carrying value cannot be increased due to subsequent changes in demand forecasts. To the extent that a severe decline in forecasted demand occurs, or the Company experiences a higher incidence of inventory obsolescence due to rapidly changing technology and customer requirements, the Company may incur significant charges for excess inventory.

Risks and Uncertainties

(c) Risks and Uncertainties

The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has continued to incur losses in 2011 and the six months ended June 30, 2012. As of June 30, 2012, the Company had approximately $13.1 million in cash and cash equivalents and $10.0 million in current debt outstanding under its revolving line of credit and letter of credit facility (the “WFB Facility”). The Company entered into the new WFB Facility on March 13, 2012 to replace its former revolving line of credit and letter of credit facility and provide liquidity and working capital through March 12, 2014, as discussed in Note 7.

The global unfavorable economic and market conditions could impact the Company’s business in a number of ways, including:

• Potential deferment of purchases and orders by customers;

• Customers’ inability to obtain financing to make purchases from the Company and/or maintain their business;

• Negative impact from increased financial pressures on third-party dealers, distributors and retailers; and

• Negative impact from increased financial pressures on key suppliers.

If the economic, market and geopolitical conditions in the United States and the rest of the world do not continue to improve or if they deteriorate, the Company may experience material adverse impacts on its business, operating results and financial condition.

The Company expects that its operating losses may continue. In order to meet the Company’s liquidity needs and finance its capital expenditures and working capital needs for the business, the Company may be required to sell assets, issue debt or equity securities or borrow on unfavorable terms. Continued uncertainty in credit markets may negatively impact the Company’s ability to access debt financing or to refinance existing indebtedness in the future on favorable terms, or at all. The Company may be unable to sell assets, issue securities or access additional indebtedness to meet these needs on favorable terms, or at all. As a result, the Company may become unable to pay its ordinary expenses, including its debt service, on a timely basis. The Company’s current lack of liquidity could harm it by:

• increasing its vulnerability to adverse economic conditions in its industry or the economy in general;

• requiring substantial amounts of cash to be used for debt servicing, rather than other purposes, including operations;

• limiting its ability to plan for, or react to, changes in its business and industry; and

• influencing investor and customer perceptions about its financial stability and limiting its ability to obtain financing or acquire customers.

If additional capital is raised through the issuance of debt securities or other debt financing, the terms of such debt may include covenants, restrictions and financial ratios that may restrict the Company’s ability to operate its business. Likewise, any equity financing could result in additional dilution of the Company’s stockholders. If the Company is unable to obtain additional capital or is required to obtain additional capital on terms that are not favorable, it may be required to reduce the scope of its planned product development and sales and marketing efforts beyond the reductions it has previously taken. Based on the Company’s current plans and business conditions, it believes that its existing cash, cash equivalents and available credit facilities will be sufficient to satisfy its anticipated cash requirements for the next twelve months.

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

Revenue Recognition

(e) Revenue Recognition

The Company recognizes revenue when the earnings process is complete. The Company recognizes product revenue upon shipment of product under contractual terms which transfer title to customers upon shipment, under normal credit terms, net of estimated sales returns and allowances at the time of shipment. The Company’s arrangements generally do not have any significant post-delivery obligations. If the Company’s arrangements include customer acceptance provisions, revenue is recognized upon obtaining the signed acceptance certificate from the customer, unless the Company can objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement prior to obtaining the signed acceptance. In those instances where revenue is recognized prior to obtaining the signed acceptance certificate, the Company uses successful completion of customer testing as the basis to objectively demonstrate that the delivered products or services meet all the acceptance criteria specified in the arrangement. The Company also considers historical acceptance experience with the customer, as well as the payment terms specified in the arrangement, when revenue is recognized prior to obtaining the signed acceptance certificate. When collectability is not reasonably assured, revenue is recognized when cash is collected.

The Company makes certain sales to product distributors. These customers are given certain privileges to return a portion of inventory. Return privileges generally allow distributors to return inventory based on a percent of purchases made within a specific period of time. The Company recognizes revenue on sales to distributors that have contractual return rights when the products have been sold by the distributors, unless there is sufficient customer specific sales and sales returns history to support revenue recognition upon shipment. In those instances when revenue is recognized upon shipment to distributors, the Company uses historical rates of return from the distributors to provide for estimated product returns. The Company accrues for warranty costs, sales returns and other allowances at the time of shipment based on historical experience and expected future costs.

The Company’s products and services qualify as separate units of accounting and are deemed to be non-contingent deliverables as the Company’s arrangements typically do not have any significant performance, cancellation, termination and refund type provisions. Products are typically considered delivered upon shipment. Revenue from services is recognized ratably over the period during which the services are to be performed.

The Company derives revenue primarily from stand-alone sales of its products. In certain cases, the Company’s products are sold along with services, which include education, training, installation, and/or extended warranty services. The Company has established third-party evidence of selling price (“TPE”) for its training, education and installation services. TPE is determined based on competitor prices for similar deliverables when sold separately. These service arrangements are typically short term in nature and are largely completed shortly after delivery of the product. Training and education services are based on a daily rate per person and vary according to the type of class offered. Installation services are based on daily rate per person and vary according to the complexity of the products being installed.

Extended warranty services are priced based on the type of product and are sold in one to five year durations. Extended warranty services include the right to warranty coverage beyond the standard warranty period. In substantially all of the arrangements with multiple deliverables pertaining to arrangements with these services, the Company has used and intends to continue using vendor-specific objective evidence of selling price (“VSOE”) to determine the selling price for the services. The Company determines VSOE based on its normal pricing practices for these specific services when sold separately.

In most instances, particularly as it relates to products, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish the selling price of each element based on TPE. Generally, the Company’s marketing strategy differs from that of the Company’s peers and the Company’s offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE for the Company’s products.

When the Company is unable to establish selling price using VSOE or TPE, the Company uses best estimate of selling price (“BSP”). The objective of BSP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The BSP of each deliverable is determined using average discounts from list price from historical sales transactions or cost plus margin approaches based on the factors, including but not limited to, the Company’s gross margin objectives and pricing practices plus customer and market specific considerations.

Fair Value of Financial Instruments

(f) Fair Value of Financial Instruments

The Company utilizes the market approach to measure fair value of its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

The Company utilizes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:

Level 1 -	Inputs are quoted prices in active markets for identical assets or liabilities.
Level 2 -	Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.
Level 3 -	Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The following financial instruments are not measured at fair value on the Company’s condensed consolidated balance sheet as of June 30, 2012, but require disclosure of their fair values: cash and cash equivalents and debt. The estimated fair value of such instruments at June 30, 2012 approximated their carrying value as reported on the condensed consolidated balance sheet. The fair value of cash and cash equivalents would be categorized as Level 1 at June 30, 2012 and December 31, 2011. The fair value of the Company’s debt obligations approximates fair value based on Level 2 inputs at June 30, 2012 and December 31, 2011. The fair value of debt is determined using the income approach based on the present value of the estimated cash flows.

The Company had no financial assets and liabilities as of June 30, 2012 recorded at fair value.

Concentration of Risk

(g) Concentration of Risk

The Company’s customers include competitive and incumbent local exchange carriers, competitive access providers, Internet service providers, wireless carriers and resellers serving these markets. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Allowances are maintained for potential doubtful accounts. For the three and six months ended June 30, 2012, Global Village Telecom (“GVT”) accounted for 10% and 12% of net revenue, respectively. For the three and six months ended June 30, 2012, Axtel S.A.B. DE C.V. (“Axtel”) accounted for 11% and 8% of net revenue, respectively. For both the three and six months ended June 30, 2011, GVT accounted for 7% of net revenue. For the three and six months ended June 30, 2011, Axtel accounted for 8% and 6% of net revenue, respectively.

As of June 30, 2012, Emirates Telecommunications Corporation (“Etisalat”), GVT and Axtel accounted for 19%, 11% and 13% of net accounts receivable, respectively. As of December 31, 2011, the same customers accounted for 29%, 2% and 24% of net accounts receivable, respectively.

As of June 30, 2012 and December 31, 2011, receivables from customers in countries other than the United States represented 70% and 71%, respectively, of net accounts receivable.

Property and Equipment

(h) Property and Equipment

Property and equipment are stated at cost and depreciated using the straight-line method over their estimated useful lives. Useful lives of all property and equipment range from 3 to 5 years. Leasehold improvements are generally amortized over the shorter of their useful lives or the remaining lease term.

Inventories

(i) Inventories

Inventories are stated at the lower of cost or market, with cost being determined using the first-in, first-out (FIFO) method. In assessing the net realizable value of inventories, the Company is required to make judgments as to future demand requirements and compare these with the current or committed inventory levels. Once inventory has been written down to its estimated net realizable value, its carrying value cannot be increased due to subsequent changes in demand forecasts. To the extent that a severe decline in forecasted demand occurs, or the Company experiences a higher incidence of inventory obsolescence due to rapidly changing technology and customer requirements, the Company may incur significant charges for excess inventory.

Credit Facility

In March 2012, the Company’s former revolving credit and letter of credit facility with Silicon Valley Bank expired, and the Company entered into its new $25.0 million WFB Facility with WFB to provide liquidity and working capital through March 12, 2014.

Under the WFB Facility, the Company has the option of borrowing funds at agreed upon interest rates. The amount that the Company is able to borrow under the WFB Facility varies based on eligible accounts receivable, as defined in the agreement, as long as the aggregate amount outstanding does not exceed $25.0 million less the amount committed as security for various letters of credit, which at June 30, 2012 was $11.4 million. To maintain availability of funds under the WFB Facility, the Company pays a commitment fee on the unused portion. The commitment fee is 0.25% per annum and is recorded as interest expense.

Under the WFB Facility, $10.0 million was outstanding at June 30, 2012. In addition, $11.4 million was committed as security for various letters of credit and the Company had $2.3 million unused availability under the WFB Facility as of June 30, 2012. The amounts borrowed under the WFB Facility bear interest, payable monthly, at a floating rate equal to the three-month LIBOR plus a margin of 3.5%. The interest rate on the WFB Facility was 3.97% at June 30, 2012.

The Company’s obligations under the WFB Facility are secured by substantially all of its personal property assets and those of its subsidiaries that guarantee the WFB Facility, including their intellectual property. The WFB Facility contains certain financial covenants, and customary affirmative covenants and negative covenants. If the Company does not comply with the various covenants and other requirements under the WFB Facility, WFB is entitled to, among other things, require the immediate repayment of all outstanding amounts and sell the Company’s assets to satisfy the obligations under the WFB Facility. As of June 30, 2012, the Company was in compliance with these covenants.

Net Loss Per Share

(6) Net Loss Per Share

Basic net loss per share is computed by dividing the net loss applicable to holders of common stock for the period by the weighted average number of shares of common stock outstanding during the period. The calculation of diluted net loss per share gives effect to common stock equivalents; however, potential common equivalent shares are excluded if their effect is antidilutive. Potential common equivalent shares are composed of incremental shares of common equivalent shares issuable upon the exercise of stock options and warrants.

The following tables set forth potential common stock that is not included in the diluted net loss per share calculation because their effect would be anti-dilutive for the periods indicated (in thousands, except exercise price per share data):

Income Taxes

(10) Income Taxes

The total amount of unrecognized tax benefits, including interest and penalties, at June 30, 2012 was not material. The amount of tax benefits that would impact the effective rate, if recognized, is not expected to be material. There were no significant changes to unrecognized tax benefits during the quarters ended June 30, 2012 and 2011. The Company does not anticipate any significant changes with respect to unrecognized tax benefits within the next 12 months.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The open tax years for the major jurisdictions are as follows:

•   Federal	2008 – 2011
•   California and Canada	2007 – 2011
•   Brazil	2006 – 2011
•   Germany	2005 – 2011
•   United Kingdom	2007 – 2011

However, due to the fact the Company had net operating losses and credits carried forward in most jurisdictions, certain items attributable to technically closed years are still subject to adjustment by the relevant taxing authority through an adjustment to tax attributes carried forward to open years.

In addition, to the extent the Company is deemed to have a sufficient connection to a particular taxing jurisdiction to enable that jurisdiction to tax the Company but the Company has not filed an income tax return in that jurisdiction for the year(s) at issue, the jurisdiction would typically be able to assert a tax liability for such years without limitation on the number of years it may examine.

The Company is not currently under examination for income taxes in any material jurisdiction.

Other Commitments

The Company is currently under audit examination by several state taxing authorities for non-income based taxes. The Company has reserved an estimated amount which the Company believes is sufficient to cover potential claims.

Performance Bonds

In the normal course of operations, the Company arranges for the issuance of various types of surety bonds, such as bid and performance bonds, which are agreements under which the surety company guarantees that the Company will perform in accordance with contractual or legal obligations. If the Company fails to perform under its obligations, the maximum potential payment under these surety bonds would have been $7.4 million as of June 30, 2012.

Purchase Commitments

The Company has agreements with various contract manufacturers which include non-cancellable inventory purchase commitments. The Company’s inventory purchase commitments typically allow for cancellation of orders 30 days in advance of the required inventory availability date as set by the Company at time of order. The amount of non-cancellable purchase commitments outstanding was $7.2 million as of June 30, 2012.

Royalties

The Company has certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a dollar amount per unit shipped or a percentage of the underlying revenue and is recorded in cost of revenue.

Legal Proceedings

The Company is subject to various legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, the Company does not expect that the ultimate costs to resolve these matters will have a material adverse effect on its consolidated financial position or results of operations. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on the results of operations of the period in which the ruling occurs, or future periods.
