Industry Background

Industry Trends

The telecommunications industry has undergone periods of significant change since data-centric applications first began to have an impact on service
provider infrastructure networks in the mid 1990s. Following deregulation and privatization in the global telecommunications industry during the late 1990s, there were many new entrants into the service provider market. Emerging service
providers built networks and began competing with incumbent service providers in an effort to accommodate rapid traffic growth and projected growth in demand for bandwidth and telecommunication services. In early 2001, however, due to excess
capacity resulting from the over building of the telecommunications infrastructure, service providers began curtailing their capital spending for network build-outs. This caused a slowdown in service provider equipment purchases and a sharp decline
in demand for networking equipment, resulting in significant industry consolidation and the failure of many service providers.

Despite the
decline in the telecommunications industry discussed above, overall data traffic on current service provider networks has continued to steadily grow as consumers and businesses increasingly use these networks for applications such as electronic
mail, web browsing, mobile communications, electronic commerce, social networking, and other content-rich video and multimedia data services. During the past several years, the communications industry as a whole began to emerge from this period of
sharp decline. Despite this growth, consolidation among some of the larger service providers resulted in a trend among these service providers to reduce the number of communications equipment suppliers in their networks. This results in
concentration of purchasing power, pricing pressure, and competitive leverage for incumbent equipment suppliers.

##### Table of Contents

Today, large and small enterprises, organizations such as government agencies and utility companies, and
individual consumers increasingly rely on high-capacity network services for a broad range of business and personal communications applications. In response to increased demand for consumer and enterprise communications services, we believe that
wireline and wireless service providers will continue to invest in networking technology that will allow them to optimize their access and core network architectures for the flexible delivery of reliable, high-capacity network services.

Intelligent Bandwidth Management

Multiservice
access, regional backhaul, and core optical networks are critical components of high-capacity communications networks that enable service providers to deliver a range of content-rich voice, video, and data services to their customers. Sycamore
products enable service providers to cost-efficiently and reliably distribute, manage and scale service bandwidth across multiservice access and optical segments of the network.

We believe that the service providers competitive advantage and differentiation comes from its ability to provide bandwidth when and where needed
and to create and offer new services quickly and cost-effectively. Given the global competitive landscape within the communications industry, we believe that many service providers will want to optimize capital expenditures, lower operating costs
and improve the profitability of next generation, converged voice, video and data services.

In the optical network segment, many service
providers own and operate traditional infrastructure networks that originally were designed primarily to support low-speed voice traffic and point-to-point data traffic with moderate bandwidth demands. These traditional network architectures impose
a number of limitations on a service providers ability to offer flexible high-speed services that provide a competitive advantage due to the following factors:



| |  |  | Networks initially designed for voice traffic. Incumbent service providers initially built and operated their networks to transmit voice traffic using
specialized equipment and sophisticated operational processes. As a result, these networks cannot easily or cost-effectively accommodate the increasing levels of content-rich voice, video and data optimized communications traffic.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Inefficient utilization of network capacity. In traditional optical networks, at most one half of the available capacity is used for delivering services. The
other portion remains idle in the event of a network failure. This traditional architecture supports the high-availability requirements of traditional voice services, but is inefficient for data traffic, which is more dynamic in nature and does not
always require the same level of protection.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expensive to build and operate. Having separate networks to carry different traffic types is capital-intensive and requires the interconnection and
management of multiple network devices. These separate devices require substantial space and power, and increase the cost and complexity of network operations.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Time consuming, complex service delivery. In traditional optical networks, the delivery of high-speed services is a highly complex, labor-intensive process
that requires a highly skilled workforce and can take months to complete.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Difficult and expensive network expansion.Adding or changing high-speed services in traditional optical networks is difficult and expensive. As a result,
service providers cannot quickly or cost-effectively respond to unplanned changes in their customers demand or accommodate rapid increases in data network traffic.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Limited ability to offer new services.The inefficient nature of traditional optical networks limits the types of high-speed services that can be offered to
customers. In addition, the slow provisioning and high cost of creating and managing high-speed services in traditional optical networks impacts a service providers market competitiveness.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Services

We offer complete engineering, furnishing, installation and testing services as well as comprehensive customer support and maintenance from multiple
locations worldwide. Our broad services portfolio, in-house experts and international partners have earned a reputation for excellence from many of the worlds largest service providers.

Customers

Our current and prospective customers
include domestic and international wireline and wireless network service providers, utility companies, multiservice operators (MSOs) and government entities with private fiber networks (collectively referred to as service providers). We
expect that our revenue will continue to be highly concentrated in a relatively small number of customers.

During the year ended
July 31, 2008, two customers, Sprint Corporation and Nokia Siemens, accounted for 23% and 22% of our revenue, respectively. During the year ended July 31, 2007, two customers, Sprint Corporation and Vodafone Group PLC, accounted for 53%
and 16% of our revenue, respectively. During the year ended July 31, 2006, three customers, Vodafone Group PLC, Sprint Corporation and Siemens, accounted for 43%, 26% and 19% of our revenue, respectively. International revenue was 48% of total
revenue during the year ended July 31, 2008, compared to 27% during the year ended July 31, 2007, and 67% during the year ended July 31, 2006. See Concentrations and Significant Customer Information and Segment
Information in Note 2 to Notes to Consolidated Financial Statements and Item 1A. Risk Factors for additional details.

Our contracts with customers typically include the purchase of our hardware products, right to use fees, the license of our SILVX or ENvision Plus network management systems, and in some cases, maintenance and support
services. These contracts include terms and conditions, including payment, delivery and termination that

##### Table of Contents

we believe are customary and standard in our industry. None of our customers are contractually committed to purchase any minimum quantities of products from
us and orders are generally cancelable prior to shipment. In addition, the federal government may terminate their contracts with any party at any time. As a result, we do not disclose our order backlog, since we believe that our order backlog at any
particular date is not necessarily indicative of actual revenue for any future period.

Sales and Marketing

There are a limited number of current and prospective optical switch customers in each geographic market. Each service provider owns and operates a unique
fiber optic network. The network complexity affects the integration of our optical networking products into each service providers network. As a result, sales are made on a customer-by-customer basis and the sales cycle may extend beyond one
year.

We sell our products worldwide through a direct sales force with a local presence in several locations around the world. In certain
markets, we also have strategic distribution partners, independent marketing representatives or independent sales consultants. We intend to further establish relationships with select distribution and marketing partners to extend our reach to serve
new markets.

The primary focus of our sales efforts is to continue to develop strong relationships with incumbent service providers and
resellers. Our sales and pre-sales engineering organizations work collaboratively with both current and prospective customers to identify optical switching applications that help optimize their network as well as create new services that they can
offer to their customers. We also provide comprehensive post-sales customer support including network planning and deployment, technical assistance centers and logistics support. Our customer support organization leverages a network of highly
qualified service partners to extend our reach and capabilities.

In support of our sales efforts, we conduct a variety of outbound
marketing programs to position and promote market awareness of Sycamore and our products to customers and prospects. These programs include tradeshows and events, industry conferences, media communications and advertising.

Research and Development

We believe that ongoing
investment in research and development is necessary in order to continue to provide innovative, intelligent bandwidth management solutions that meet our current and prospective customers needs. We believe that our solutions will allow current
and prospective customers to optimize bandwidth and capacity management while also allowing them to reduce their capital expenditures and operating costs. In order to provide such products to our customers, we believe we must make sustained
investment in research and development. Our research and development efforts focus on improvements to the features and functionality of existing products, while also developing next-generation systems. We intend to continue to focus our research and
development efforts on solutions that help our customers optimize their networks for the content-rich voice, video and data services driving network growth.

Our research and development expenditures were $47.4 million, $45.9 million and $31.4 million for the years ended July 31, 2008, 2007 and 2006, respectively. All of our expenditures for research and development,
as well as share-based compensation expense relating to research and development of $1.8 million, $1.7 million and $2.4 million, for the years ended July 31, 2008, 2007 and 2006, respectively, have been expensed as incurred.

Competition

The number of optical switching
opportunities worldwide is limited. Competition for these opportunities is intense and includes considerable pricing pressure. Based on the current level of spending by communications service providers, we expect that competition will continue to be
very intense.

##### Table of Contents

Sycamores competition includes large incumbent suppliers of network infrastructure equipment and
optical networking equipment, such as Alcatel-Lucent, Ciena, Cisco, Ericsson, Fujitsu, Huawei, Nortel, Nokia Siemens Networks and Tellabs. The multiservice access market is equally competitive, with a highly fragmented group of suppliers which
includes Tellabs, Alcatel-Lucent, Adtran and Kentrox. Many of our established competitors have longer operating histories and greater financial, technical, sales, marketing, manufacturing and field resources and are able to devote greater resources
to the research and development of new products than we do. In addition, these competitors generally have more diverse product lines which allow them the flexibility to price their products more aggressively and absorb the significant cost structure
associated with optical switching research and development across their entire business. Most of our competitors also have more extensive customer bases and broader customer relationships than we do, including relationships with our prospective
customers in their local geographies. In addition, we continue to see new entrants into the market with new products that compete with our products. Some of these new entrants are located in geographies with lower cost infrastructures than ours. In
order to compete effectively in the optical switching market, we must deliver products that:



| |  |  | provide a cost-competitive solution to service providers for expanding capacity and provides intelligent bandwidth management;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | lower a service providers cost of building and operating their fiber optic network;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | provide extremely high network reliability;
| | - |  | -------------------------------------------



| |  |  | interoperate with existing network devices;
| | - |  | -------------------------------------------



| |  |  | simplify the network architecture by replacing multiple traditional networking devices into a single compact optical switch; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide effective network management.
| | - |  | -------------------------------------

In addition, we believe that our knowledge of communications infrastructure requirements and experience working with service providers to assist in the deployment of new services for their customers are important competitive factors in our
market.

Proprietary Rights and Licensing

Our success and ability to compete are dependent on our ability to develop and maintain the proprietary aspects of our technology and to operate without infringing on the proprietary rights of others. We rely on a
combination of patent, trademark, trade secret and copyright law and contractual restrictions to protect the proprietary aspects of our technology. We license software to our customers pursuant to signed or shrink-wrapped license agreements, which
impose certain restrictions on the licensees ability to utilize the software. Our practice is to require employees and consultants to execute non-disclosure and proprietary rights agreements upon commencing employment or consulting with us.
Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. We enforce our intellectual property rights vigorously against
infringement or misappropriation.

We license third party software, including certain technologies that are (i) embedded into our
hardware platforms and into our SILVX and ENvision Plus network management systems; (ii) used internally by us as hardware design tools; and (iii) used internally by us as software development tools. We also utilize publicly available
technology. The majority of these licenses have perpetual terms but will generally terminate after an uncured breach of the agreement by us. We believe, based upon past experience and standard industry practice, that such licenses generally could be
obtained on commercially reasonable terms in the future. Nonetheless, there can be no assurance that the necessary licenses would be available on acceptable terms, if at all.

As of July 31, 2008, we had received 38 United States patents and had pending 3 United States patent applications. Of the United States patents that
have been issued, the earliest any will expire is February 2019. As of July 31, 2008, we had 8 allowed or registered United States trademarks and 17 allowed or registered foreign trademarks. All of the registered United States trademarks have a
duration of ten years from the date of application, the earliest of which will expire in February 2011.

Manufacturing

We source our products through a combination of contract manufacturers for our custom designed products and original equipment manufacturers.

We utilize contract manufacturers, who provide manufacturing services, including material procurement and handling, printed circuit board assembly, mechanical assembly, and direct shipment to our customers. We design,
specify and monitor all of the tests performed by contract manufacturers to meet our internal and external quality standards. We work closely with our contract manufacturers to manage costs and delivery times. Our contract manufacturing agreements
generally have indefinite terms and are cancelable by either party upon written notice.

We utilize original equipment manufacturers that
have made available to us existing products providing our customers with complete product solutions. We monitor the tests performed by original equipment manufacturers to meet our internal and external quality standards. We also insure that our
original equipment manufacturers are compliant with global standards for quality, environmental responsibility, and employee welfare. Our original equipment manufacturer agreements are focused on providing continuation of supply over an indefinite
period and are cancelable through narrowly defined conditions.

We believe that our sourcing strategy enables us to deliver products more
quickly and allows us to focus on our core competencies, including research and development, sales and customer service.

We have limited
internal manufacturing operations. Our internal manufacturing operations primarily consist of quality assurance for materials and components, final testing, assembly and shipment of selected products, and depot repair of products. We also use a
limited number of other manufacturers to supply certain non-significant product sub-assemblies and components.

Our custom designed
intelligent bandwidth management products utilize hundreds of individual component parts, some of which are customized for our products. Component suppliers in the specialized, high technology end of the optical communications industry are generally
not as plentiful or, in some cases, as reliable, as component suppliers in more mature industries. We work closely with our strategic component suppliers to either secure a long-term supply source or to pursue new component technologies that could
either reduce cost or enhance the performance of our products.

Component suppliers continue to adjust manufacturing capacity versus demand
while rationalizing product lines based on future demand. Several suppliers have exited the optical components market, and others have announced reductions of their product offerings. These announcements, or similar decisions by other suppliers,
could result in reduced competition and higher prices for the components we purchase. In addition, the loss of a source of supply for key components could require us to incur additional costs to redesign our products that use those components or to
stockpile component inventory for production of future product.

Employees

As of July 31, 2008, we employed 492 persons of which 278 were primarily engaged in research and development, 54 in sales and marketing, 39 in
customer service and support, 54 in manufacturing, and 67 in general and administration. None of our employees are currently represented by a collective bargaining unit. We believe our relations with our employees are good.

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Set forth below and elsewhere in this
report and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward looking statements contained in this report.

Our results may be adversely affected by unfavorable conditions in the telecommunications industry and the economy in general.

We expect industry and economic conditions to affect our business in many ways, including the following:



| |  |  | our current and prospective customers may make limited capital expenditures;
| | - |  | ----------------------------------------------------------------------------



| |  |  | consolidation of our customers may cause delays, disruptions or reductions in their capital spending plans as well as increase their relative purchasing power in
any negotiation;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we will continue to have limited ability to forecast the volume and product mix of our sales;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | we will experience a continuing high level of competition as a result of limited demand and we may experience downward pressure on the pricing of our products which
reduces gross margins and constrains revenue growth;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | many of our competitors have more diverse product lines which allow them the flexibility to price their products more aggressively;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | new competitive entrants may be located in geographies with lower cost infrastructures than ours allowing them a greater degree of price flexibility;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we will need to continue to balance our initiatives to manage our operating costs against the need to keep pace with technological advances;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the convergence of service provider network architecture on more common and undifferentiated solutions versus technical innovation may create new competitive
challenges;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | intense competition may enable customers to demand more favorable terms and conditions of sales including extended payment terms; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | any bankruptcies or weakening financial condition of any of our customers may require us to write off amounts due from prior sales.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------

These factors could have an adverse impact on our revenue, operating results and financial condition.

We currently depend entirely on our optical switching and multiservice access products and our revenue depends upon their commercial success.

Our revenue depends on the commercial success of our line of optical switching and multiservice access products and the service revenues related to such
products. Our research and development efforts focus exclusively on these products. In order to remain competitive, we believe that continued investment in research and development is necessary in order to provide innovative solutions to our current
and prospective customers. We cannot assure you that we will be successful in:



| |  |  | anticipating and successfully meeting evolving customer requirements;
| | - |  | ---------------------------------------------------------------------



| |  |  | completing the development, introduction or production of new products; or
| | - |  | --------------------------------------------------------------------------



| |  |  | enhancing our existing products.
| | - |  | --------------------------------

##### Table of Contents

If our current and prospective customers do not adopt our optical switching and multiservice access
products and do not purchase and successfully deploy our current and future products, our business, operating results and financial condition could be materially adversely affected.

Industry consolidation may lead to increased competition and may harm our business.

The
communications industry has experienced consolidation and we expect this trend to continue. Several larger communications service providers have announced merger transactions which will have a significant impact on the telecommunications industry.
Such consolidation among our customers may cause delays or reductions in their capital expenditure plans and may cause increased competitive pricing pressures as the number of available customers declines and their relative purchasing power
increases in relation to suppliers. Consolidation may also result in a combined entity choosing to standardize on a certain vendors optical networking platform. Any of these factors could adversely affect our business.

Matters related to the investigations into our historical stock option granting practices and the resulting restatements of our previously issued financial statements
may result in additional litigation, regulatory proceedings and government enforcement actions.

Although on July 9, 2008, we
entered into an agreement with the SEC settling the civil charges contained in the SECs complaint, without admitting or denying such charges, our historical stock option granting practices and the initial restatement and further restatement of
our previously issued financial statements have exposed us to risks associated with litigation, regulatory proceedings and government enforcement actions. For more information regarding our current litigation and related inquiries, please see Part
I, Item 3- Legal Proceedings as well as the other risk factors related to litigation set forth herein and in Item 1A to our Form 10-K.

While we believe that we have made appropriate judgments in determining the correct measurement dates for our stock option grants, the SEC may disagree with the manner in which we accounted for and reported the
corresponding financial impact. Accordingly, there is a risk that we may have to further restate our prior financial statements, amend prior filings with the SEC, or take other actions not currently contemplated.

No assurance can be given regarding the potential costs or outcomes from any continuing litigation, regulatory proceedings or government enforcement
actions relating to our past stock option practices. The resolution of these matters may be time consuming, expensive, and may distract management from the conduct of our business. The SEC enforcement action may damage our reputation and negatively
impact our ability to renew or enter into new contracts with commercial and government customers. Further, as a result of our settlement with the SEC, we will be unable to utilize a short form registration statement on Form S-3 until
July 10, 2011, which is three years from the settlement of the SEC enforcement action. This could adversely affect our financial condition or our ability to pursue specific strategic alternatives which could impact our ability to pursue
strategic acquisitions.

We may experience risks in our investments due to changes in the market, which could adversely affect the value or liquidity of
our investments.

At July 31, 2008, we had $499.9 million in cash and cash equivalents plus $441.9 million in investments
in marketable debt securities. We maintain a portfolio of cash equivalents and short-term and long-term investments in a variety of securities which may include commercial paper, certificates of deposit, money market funds and government debt
securities. These available-for-sale investments are subject to interest rate risk and may decline in value if market interest rates increase. These investments are subject to general credit, liquidity, market and interest rate risks. As a result,
we may experience a reduction in value or loss of liquidity of our investments. In addition, should any investment cease paying or reduce the amount of interest paid to us, our interest income would suffer. These market risks associated with our
investment portfolio may have a negative adverse effect on our results of operations, liquidity and financial condition.

##### Table of Contents

If we fail to successfully integrate the operations of acquisitions, we may not realize the potential benefits of the
acquisition and our business, results of operations and financial condition could be harmed.

We have made, and may continue to make,
acquisitions in order to enhance our business. In fiscal 2007, we acquired Eastern Research, and decided to discontinue the development of Eastern Researchs OX8000 and BSG products. As a result of the Companys decision to discontinue
these products, we recorded asset impairment charges of $6.6 million and $10.7 million, respectively. In fiscal 2008 the Company performed its annual impairment testing, and as a result an asset impairment charge was taken related to Eastern
Researchs DNX technology and customer relationships for a total of $4.4 million.

Acquisitions involve numerous risks, including
problems combining the purchased operations, technologies or products, unanticipated costs, diversion of managements attention from our core businesses, adverse effects on existing business relationships with suppliers and customers, risks
associated with entering markets in which we have no or limited prior experience and potential loss of key employees. There can be no assurance that we will be able to successfully integrate any businesses, products, technologies or personnel that
we have acquired or might acquire. If we fail in our integration efforts with respect to our acquisitions and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures,
financial controls and human resources practices, our business and financial condition may be adversely affected. It is also possible that the businesses we have acquired, or any other businesses we may acquire in the future, may perform worse than
expected or prove to be more difficult to integrate and manage than expected. In that event, there may be a material adverse effect on our business, results of operations and financial condition. In addition, the goodwill and intangible assets
associated with acquisitions are subject to impairment testing on a regular basis, such charges would have the effect of decreasing our earnings or increasing our losses in such period. If we are required to take a substantial impairment charge, our
earnings could be materially adversely affected in such period.

We must continue to make investments in product development in order to keep pace with
technological advances and succeed in existing and new markets for our products.

In order to be successful, we must balance our
initiatives to reduce operating costs against the need to keep pace with technological advances. The markets for our products are characterized by rapidly changing technology, frequent introductions of new products and evolving customer
requirements. To succeed, we must continue to develop new products and new features for existing products that meet customer requirements and market demand. We may fail to develop products that incorporate new technologies highly sought after by
customers. We may also allocate development resources toward products or technologies for which market demand is ultimately lower than anticipated. Managing our efforts to keep pace with new technologies and reduce operating expense is difficult and
there is no assurance that we will be successful. We expect that our decision to make substantial investments in product development will require us to generate future revenue above current levels in order to achieve and maintain operating
profitability. Until such time, or if we fail to generate different revenue, we may incur net losses. We cannot assure you that our revenue will increase or that we will generate sufficient revenue to achieve or sustain such operating profitability.

We face intense competition that could adversely affect our sales and profitability.

Competition for limited optical switching opportunities is intense and continues to be dominated by large, incumbent equipment suppliers. Competition is
based upon a combination of price, established customer relationships, broad product portfolios, large service and support teams, functionality and scalability. Large companies, such as Alcatel-Lucent, Ciena, Ericsson, Nortel and Tellabs have
historically dominated this market. Many of our competitors have longer operating histories and greater financial, technical, sales, marketing and manufacturing resources than we do and are able to devote greater resources to the research and
development of new products. These competitors also have long standing existing relationships with our current and prospective customers. New competitors, such as Huawei, have entered the optical networking market using the latest available
technology and aggressive pricing tactics in order to compete with our products. Our competitors may



14

##### Table of Contents

forecast market developments more accurately and could develop new technologies that compete with our products or even render our products less desirable or
even obsolete. Moreover, these competitors have more diverse product lines which allow them the flexibility to price their products more aggressively. The multiservice access market is equally competitive, with a highly fragmented group of
suppliers.

As a result of the intensified competition, we expect to encounter aggressive tactics such as the following:



| |  |  | price discounting;
| | - |  | ------------------



| |  |  | early announcements of competing products and other marketing efforts;
| | - |  | ----------------------------------------------------------------------



| |  |  | customer financing assistance;
| | - |  | ------------------------------



| |  |  | complete solution sales from one single source;
| | - |  | -----------------------------------------------



| |  |  | bundling multi-vendor solution integration services with turnkey network operating service offerings;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | marketing and advertising assistance; and
| | - |  | -----------------------------------------



| |  |  | intellectual property disputes.
| | - |  | -------------------------------

These tactics may be effective in a highly concentrated customer base like ours. Our customers are under increasing pressure to deliver their services at the lowest possible cost. As a result, the price of an optical networking system may
become an important factor in customer decisions. In certain cases, our larger competitors have more diverse product lines that allow them the flexibility to price their products more aggressively and absorb the significant cost structure associated
with optical switching research and development across their entire business. If we are unable to offset any reductions in the average selling price of our products by a reduction in the cost of our products, our gross margins will be adversely
affected.

If we are unable to compete successfully against our current and future competitors, we could experience revenue reductions,
order cancellations and reduced gross margins, any one of which could have a material adverse effect on our business, operating results and financial condition.

Substantially all of our revenue is generated from a limited number of customers, and our success depends on increasing both direct sales and indirect sales through distribution channels to a limited number of service providers.

Our revenue is concentrated among a limited number of customers. None of our customers are contractually committed to purchase any minimum
quantities of products from us and orders are generally cancelable prior to shipment. We expect that our revenue will continue to depend on sales of our products to a limited number of customers. While expanding our customer base is a key objective,
at the present time, the number of prospective customer opportunities for our products is limited. In addition, we believe that the telecommunications industry will continue in a consolidation phase which may further reduce the number of prospective
customers, slow purchases and delay optical switching deployment decisions.

Our direct sales efforts primarily target service providers,
many of which have already made significant investments in traditional optical networking infrastructures. In addition, we are utilizing established channel relationships with distribution partners including resellers, distributors and systems
integrators for the sale of our products to service providers including the federal government. We have entered into agreements with several distribution partners, some of whom also sell products that compete with our products. We cannot be certain
that we will be able to retain or attract distribution partners on a timely basis or at all, or that the distribution partners will devote adequate resources to selling our products. Since we have only limited experience in developing and managing
such channels, the extent to which we will be successful is uncertain. If we are unable to develop and manage new channels of distribution to sell our products to service providers, or if our distribution partners are unable to convince service
providers to deploy our optical networking solutions, our business, operating results and financial condition will be materially adversely affected.

We rely on a limited number of customers for a significant portion of our revenue and the loss of one or more of these
customers could materially harm our business.

A significant portion of our revenue is generated from a limited number of customers and
that trend is likely to continue. The loss of any one of these customers or any substantial reduction in orders by any one of these customers could materially and adversely affect our business, operating results and financial condition.

Historically we have depended on a government agency, through our reseller, for a significant amount of our revenue and the loss or decline of existing or future
government agency funding could adversely affect our revenue and cash flows.

This government agency, the Defense Information Systems
Agency (DISA), may be subject to budget cuts, budgetary constraints, a reduction or discontinuation of funding or changes in the political or regulatory environment that may cause the agency to terminate the projects, divert funds or delay
implementation or expansion. A significant reduction in funds available for the agency to purchase equipment could significantly reduce our revenue and cash flows. The significant reduction or delay in orders by the agency could also
significantly reduce our revenue and cash flows. As with most government contracts, the agency may terminate the contract at any time without cause. Additionally, government contracts are generally subject to audits and investigations by
government agencies. If the results of these audits or investigations are negative, our reputation could be damaged, contracts could be terminated or significant penalties could be assessed. If a contract is terminated for any reason, our
ability to fully recover certain amounts may be impaired resulting in a material adverse impact on our business, operating results and financial condition.

Certain larger customers may have substantial negotiating leverage, which may require that we agree to terms and conditions that may have an adverse effect on our business.

Large communications providers, key resellers and the federal government, who make up a large part of our target market, have substantial purchasing power
and potential leverage in negotiating contractual arrangements with us. These customers and prospects may require us to develop additional features and require penalties for failure to deliver such features. As we seek to increase sales into our
target markets, we may be required to agree to such terms and conditions, which may affect the timing of revenue recognition and amount of deferred revenues and may have other unfavorable effects on our business and financial condition.

Our strategy to pursue acquisitions or strategic investments may not be successful.

Our business strategy includes the ongoing consideration of acquiring or making strategic investments in companies with either complementary technologies
or in adjacent markets to add complementary products and services, expand the markets we serve and diversify our customer base. To do so, we may issue additional shares that could dilute the holdings of existing common stockholders or we may utilize
cash, or both.

Any decision regarding an acquisition or strategic investment would be subject to inherent risk, and we cannot guarantee
that we will be able to identify appropriate opportunities, successfully negotiate economically beneficial terms, successfully integrate any acquired business, retain key employees, successfully market and sell products of the acquired business or
achieve the anticipated synergies or benefits of any acquisition or strategic investment which may be selected. In implementing a strategy, we may enter markets in which we have little or no prior experience and there can be no assurance that we
will be successful. Further, there can be no assurances concerning the success, type, form, structure, nature, results, timing or terms and conditions of any such potential action.

Whether or not we pursue any acquisition or strategic investment, the value of the Companys shares may decrease.

Our business strategy includes the ongoing consideration of acquiring or making strategic investments in companies with either complementary technologies or in adjacent markets to add complementary products and
services, expand the markets we serve and diversify our customer base. We cannot predict whether, or when, we

##### Table of Contents

may be able to consummate such acquisition or strategic investment or that such acquisition or strategic investment would provide you with a positive return
on your investment. Accordingly, whether or not we pursue any such acquisition or strategic investment, the value of your shares may decrease.

Any
acquisitions or strategic investments we make could disrupt our business and materially harm our financial condition.

As part of our
business strategy, we consider acquisitions and strategic investments including those in complementary companies, products or technologies, or in adjacent market segments and otherwise. We may consider such acquisitions or strategic investments to
add complementary products and services, expand the markets we serve and diversify our customer base. In the event of an acquisition or strategic investment, we may:



| |  |  | issue stock that would dilute our current stockholders holdings;
| | - |  | -----------------------------------------------------------------



| |  |  | consume cash, which would reduce the amount of cash available for other purposes and the interest income we generate from our cash;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | incur debt or assume liabilities;
| | - |  | ---------------------------------



| |  |  | increase our ongoing operating expenses and level of capital expenditures;
| | - |  | --------------------------------------------------------------------------



| |  |  | record goodwill and non-amortizable intangible assets subject to impairment testing and potential periodic impairment charges;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| |  |  | incur amortization expenses related to certain intangible assets;
| | - |  | -----------------------------------------------------------------



| |  |  | incur large and immediate write-offs; or
| | - |  | ----------------------------------------



| |  |  | become subject to litigation.
| | - |  | -----------------------------

Our
ability to achieve the benefits of any acquisition or strategic investment, will also involve numerous risks, including:



| |  |  | problems combining the purchased operations, technologies or products;
| | - |  | ----------------------------------------------------------------------



| |  |  | difficulty in marketing and selling products of an acquired business;
| | - |  | ---------------------------------------------------------------------



| |  |  | unanticipated costs or liabilities;
| | - |  | -----------------------------------



| |  |  | diversion of managements attention from other business issues and opportunities;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | disruption to in-process product development initiatives;
| | - |  | ---------------------------------------------------------



| |  |  | adverse effects on existing business relationships with suppliers and customers;
| | - |  | --------------------------------------------------------------------------------



| |  |  | problems entering markets in which we have no or limited prior experience;
| | - |  | --------------------------------------------------------------------------



| |  |  | problems with integrating employees and potential loss of key employees; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | additional regulatory compliance issues.
| | - |  | ----------------------------------------

We cannot assure you that we will be able to successfully integrate any businesses, products, technologies or personnel that we might acquire in the future and any failure to do so could disrupt our business and seriously harm our financial
condition.

Current economic and market conditions make forecasting difficult.

Current economic and market conditions together with the inherent inconsistent and unpredictable ordering patterns of our customers have limited our
ability to forecast the volume and product mix of our sales, making it difficult to provide estimates of revenue and operating results. We continue to have limited visibility into the capital spending plans of our current and prospective customers.
Fluctuations in our revenue can lead to even



17



---

##### Table of Contents

greater fluctuations in our operating results. Our planned expense levels depend in part on our expectations of future revenue. Our planned expenses include
significant investments, particularly within the research and development organization, which we believe are necessary to continue to provide innovative optical networking and multiservice access solutions to meet our current and prospective
customers needs. As a result, it is difficult to forecast revenue and operating results. If our revenue and operating results are below the expectations of our investors and market analysts, it could cause a decline in the price of our common
stock.

The unpredictability of our quarterly results may adversely affect our common stock price.

In general, our revenue and operating results in any reporting period may fluctuate significantly due to a variety of factors including, but not limited
to:



| |  |  | fluctuation in demand for our products;
| | - |  | ---------------------------------------



| |  |  | the timing, volume and product mix of sales of our products;
| | - |  | ------------------------------------------------------------



| |  |  | changes in customer requirements, including delays or order cancellations;
| | - |  | --------------------------------------------------------------------------



| |  |  | the introduction of new products by us or our competitors;
| | - |  | ----------------------------------------------------------



| |  |  | changes in the price or availability of components for our products;
| | - |  | --------------------------------------------------------------------



| |  |  | the timing of revenue recognition and deferred revenue;
| | - |  | -------------------------------------------------------



| |  |  | readiness of customer sites for installation;
| | - |  | ---------------------------------------------



| |  |  | changes in our pricing policies or the pricing policies of our competitors;
| | - |  | ---------------------------------------------------------------------------



| |  |  | satisfaction of contractual customer acceptance criteria and related revenue recognition issues;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | manufacturing and shipment delays;
| | - |  | ----------------------------------



| |  |  | changes in accounting rules, such as the requirement to record share-based compensation expense for employee stock option grants made at fair market value; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic conditions as well as those specific to the telecommunications and related industries.
| | - |  | -------------------------------------------------------------------------------------------------------

We believe that quarter-to-quarter comparisons of our operating results are not a good indication of our future performance. You should not rely on our
results for one quarter as any indication of our future performance. The factors discussed above are extremely difficult to predict and impact our revenue and operating results. In addition, our ability to forecast our future business has been
significantly impaired by economic and market conditions. As a result, we believe that our revenue and operating results are likely to continue to vary significantly from quarter to quarter and may cause our stock price to fluctuate.

Customer purchase decisions have historically taken a long period of time. We believe that some customers who make a decision to deploy our products will
expand their networks slowly and deliberately. In addition, we could receive purchase orders on an irregular and unpredictable basis. Because of the nature of our business, we cannot predict these sales and deployment cycles. The long sales cycles,
as well as our expectation that customers may tend to issue large purchase orders sporadically with short lead times, may cause our revenue and results of operations to vary significantly and unexpectedly from quarter to quarter. As a result, our
future operating results may be below our expectations or those of public market analysts and investors, and our revenue may decline or recover at a slower rate than anticipated by us or analysts and investors. In either event, the price of our
common stock could decrease.

We utilize contract manufacturers and any disruption in these relationships may cause us to fail to meet our
customers demands and may damage our customer relationships.

We have limited internal manufacturing capabilities. We outsource
the manufacturing of our products to contract manufacturers who manufacture our products in accordance with our specifications and fill orders on a timely basis. We may not be able to manage our relationships with our contract manufacturers
effectively, and



18



---

##### Table of Contents

our contract manufacturers may not meet our future requirements for timely delivery. Our contract manufacturers also build products for other companies, and
we cannot be assured that they will have sufficient quantities of inventory available to fill our customer orders or that they will allocate their internal resources or capacity to fill our orders on a timely basis. Unforecasted customer demand may
increase the cost to build our products due to fees charged to expedite production and other related charges.

The contract manufacturing
industry is a highly competitive, capital-intensive business with relatively low profit margins, and in which acquisition or merger activity is relatively common. Qualifying a new contract manufacturer and commencing volume production is expensive
and time consuming, and could result in a significant interruption in the supply and/or quality of our products. If we are required or choose to change contract manufacturers for any reason, our revenue, gross margins and customer relationships
could be adversely affected.

We and our contract manufacturers rely on single or limited sources for supply of certain components and our business may
be seriously harmed if our supply of any of these components is disrupted.

We and our contract manufacturers purchase several key
components from single or limited sources. These key components include commercial digital signal processors, central processing units, field programmable gate arrays, switch fabric, and optical transceivers. We generally purchase our key components
on a purchase order basis and have no long-term contracts for these components. In the event of a disruption in supply of key components including, but not limited to, production disruptions, low yield or discontinuance of manufacture, we may not be
able to develop an alternate source in a timely manner or on acceptable terms. Any such failure could impair our ability to deliver products to customers or require us to purchase additional excess inventory, which would adversely affect our revenue
and operating results.

In addition, our reliance on key component suppliers exposes us to potential supplier production difficulties or
quality variations. The loss of a source of supply for key components or a disruption in the supply chain could require us to incur additional costs to redesign our products that use those components. Conversely, electronic products are experiencing
shorter product life cycles which may require us to build inventories in excess of demand.

During the past year, component suppliers have
planned their production capacity to better match demand. If the demand for certain components increases beyond the component suppliers planned production capacity, there may be component shortages which may increase procurement costs. In addition,
consolidation in the optical component industry could result in reduced competition for supply of key components and higher component prices. If any of these events occurred, our revenue and operating results could be adversely affected.

Our inability to anticipate inventory requirements may result in inventory charges or delays in product shipments.

During the normal course of business, we may provide purchase orders to our contract manufacturers for up to six months prior to scheduled delivery of
products to our customers. If we overestimate our product requirements, the contract manufacturers may assess cancellation penalties or we may have excess inventory which could negatively impact our gross margins. If we underestimate our product
requirements, the contract manufacturers may have inadequate inventory that could interrupt manufacturing of our products and result in delays in shipment to our customers. We also could incur additional charges to expedite the manufacture of our
products to meet our customer deployment schedules. If we over or underestimate our product requirements, our revenue and gross profit may be impacted.

Product performance problems could adversely affect our revenue, operating results and financial condition.

If our products do not meet our customers performance or reliability requirements, our relationships with current and prospective
customers may be adversely affected. The design, development and deployment of our products often involve problems with software, components, manufacturing processes and interoperability with other network elements. If we are unable to identify and
fix errors or other problems, or if our customers experience interruptions or delays that cannot be promptly resolved, we could experience:



| |  |  | loss of revenue or delay in revenue recognition or accounts receivable collection;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | loss of customers and market share;
| | - |  | -----------------------------------



| |  |  | inability to attract new customers or achieve market acceptance;
| | - |  | ----------------------------------------------------------------



| |  |  | diversion of development and other resources;
| | - |  | ---------------------------------------------



| |  |  | increased service, warranty and insurance costs; and
| | - |  | ----------------------------------------------------



| |  |  | legal actions by our customers.
| | - |  | -------------------------------

These factors may adversely impact our revenue, operating results and financial condition. In addition, our products are often critical to the performance of our customers network. Generally, we seek to limit liability in our customer
agreements. If we are not successful in limiting our liability, or these contractual limitations are not enforceable or if we are exposed to product liability claims that are not covered by insurance, a successful claim could harm our business.

The global nature of our business exposes us to multiple risks.

International sales have historically represented a significant amount of our total sales including 48% of total revenue for fiscal 2008 and 27% of total revenue for fiscal 2007. We have a substantial international
customer base and we are subject to foreign exchange translation risk to the extent that our revenue is denominated in currencies other than the U.S. dollar. Doing business internationally requires significant management attention and financial
resources to successfully develop direct and indirect sales channels and to support customers in international markets. In addition we have a research and development facility in Shanghai, China. We may not be able to maintain or expand
international market demand for our products.

In addition, all of our international operations are subject to inherent risks, including:



| |  |  | greater difficulty in accounts receivable collection and longer collection periods;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | difficulties and costs of staffing, managing and conducting foreign operations in compliance with local laws and customs;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | reliance on distribution partners for the resale of our products in certain markets and for certain types of product offerings, such as the integration of our
products into third-party product offerings;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the need to work with third parties in certain countries to perform installation and obtain customer acceptance may impact the timing of revenue recognition;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the need to maintain staffing, or to work with third parties, to provide service and support in international locations;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | the impact of slowdowns or recessions in economies outside the United States;
| | - |  | -----------------------------------------------------------------------------



| |  |  | unexpected changes in regulatory requirements, including trade and environmental protection measures and import and licensing requirements;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | obtaining export licensing authority on a timely basis and maintaining ongoing compliance with import, export and reexport regulations;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | certification requirements;

| |  |  | currency fluctuations;
| | - |  | ----------------------



| |  |  | reduced protection for intellectual property rights in some countries;
| | - |  | ----------------------------------------------------------------------



| |  |  | potentially adverse tax consequences; and
| | - |  | -----------------------------------------



| |  |  | political and economic instability, particularly in emerging markets.
| | - |  | ---------------------------------------------------------------------

These factors may adversely impact our revenue, operating results and financial condition.

Environmental regulations could harm our operating results.

We may be subject to various state,
federal and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products such as, but not limited to, the European Union Directive entitled, The Restriction
of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment. Environmental laws and regulations can vary from jurisdiction to jurisdiction and often make producers financially responsible for the collection, treatment,
recycling and ultimate disposal of their products. We will need to ensure that we comply with all applicable environmental laws and regulations as they are enacted, and that our component suppliers also comply on a timely basis with such laws and
regulations. If we are not in compliance with such legislation, our customers may refuse to purchase our products or we may be unable to ship products to certain markets, which would have a material adverse effect on our business, financial
condition and results of operations.

We could incur substantial costs in connection with our compliance with environmental laws and
regulations, and we could also be subject to governmental fines, penalties and liability to our customers if we were found to be in violation of these laws. If we have to make significant capital expenditures to comply with environmental laws, or if
we are subject to significant capital expenses in connection with a violation of these laws, our financial condition or operating results could suffer. Additionally, we could be forced to write off inventory that is found not to be compliant with
evolving environmental regulations.

If we are unable to retain and recruit key personnel, our business may be harmed.

We depend on the continued services of our executive officers and other key engineering, sales, marketing and support personnel, who have critical
industry experience and relationships that we rely on to implement our business strategy, many of whom would be difficult to replace. None of our officers or key employees is bound by an employment agreement for any specific term. We do not have
key person life insurance policies or similar perquisites covering any of our employees.

Virtually all of our key employees
have been granted share-based awards that are intended to represent an integral component of their compensation package. These share-based awards may not provide the intended incentive to our employees if our stock price declines, experiences
significant volatility or if our failure to make our timely SEC filings prevents our employees from receiving or exercising stock options. The loss of the services of any of our key employees, the inability to attract and retain qualified personnel
in the future, or delays in hiring qualified personnel could delay the development and introduction of our products, and negatively impact our ability to sell and support our products.

Adverse resolution of litigation and claims may harm our business, operating results or financial condition.

We are a defendant in an Initial Public Offering securities lawsuit and a party to other litigation and claims in the normal course of our business. We are also subject to one derivative action lawsuit arising from our recent stock option
investigation and related restatements of our financial statements, and we may be named in additional litigation. The highly technical nature of our products makes them susceptible to allegations of patent infringement. Litigation is by its nature
uncertain and unpredictable and there can be no assurance that the



21



---

##### Table of Contents

ultimate resolution of such claims will not exceed the amounts accrued for such claims, if any. Litigation can be expensive, lengthy, and disruptive to
normal business operations. An unfavorable resolution of a legal matter could have a material adverse affect on our business, operating results, or financial condition. For additional information regarding certain lawsuits and other disputes in
which we are involved, see Part I, Item 3 Legal Proceedings.

Our ability to compete and pursue strategic alternatives could be
jeopardized if we are unable to protect our intellectual property rights or are determined to have infringed on intellectual property rights of others.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with
our employees, consultants and corporate partners and control access to and distribution of our products, documentation and other proprietary information. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to
copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign
countries where the laws may not protect our proprietary rights as fully as in the United States. If competitors are able to use our technology, our ability to compete and pursue strategic alternatives effectively could be harmed. Litigation may be
necessary to enforce our intellectual property rights. Any such litigation could result in substantial costs and diversion of resources and could have a material adverse affect on our business, operating results and financial condition.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patents and other
intellectual property rights. In the course of our business, we may receive claims of infringement or otherwise become aware of potentially relevant patents or other intellectual property rights held by other parties. We evaluate the validity and
applicability of these intellectual property rights, and determine in each case whether we must negotiate licenses or cross-licenses to incorporate or use the proprietary technologies in our products.

Any parties asserting that our products infringe upon their proprietary rights would require us to defend ourselves, and possibly our customers,
manufacturers or suppliers against the alleged infringement. Regardless of their merit, these claims could result in costly litigation and subject us to the risk of significant liability for damages. Such claims would likely be time consuming and
expensive to resolve, would divert management time and attention and would put us at risk to:



| |  |  | stop selling, incorporating or using our products that incorporate the challenged intellectual property;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | obtain from the owner of the intellectual property right a license to sell or use the relevant technology, which license may not be available on reasonable terms,
or at all;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign those products that use such technology; or
| | - |  | ----------------------------------------------------



| |  |  | accept a return of products that use such technologies.
| | - |  | -------------------------------------------------------

If we are forced to take one or more of the foregoing actions, our business may be seriously harmed.

In
addition, we license public domain software and proprietary technology from third parties for use in our existing products, as well as new product development and enhancements. We cannot be assured that such licenses will be available to us on
commercially reasonable terms in the future, if at all. The inability to maintain or obtain any such license required for our current or future products and enhancements could require us to substitute technology of lower quality or performance
standards or at greater cost, either of which could adversely impact the competitiveness of our products.

Adverse outcomes resulting from examination of our tax returns could adversely affect our results.

We are subject to the continuous examination of our tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the
likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provisions. Our Massachusetts state income tax returns for the tax years ended July 31, 2002, 2003 and 2004 are currently under examination by the
Massachusetts Department of Revenue. While we believe that we have adequately provided for our tax liabilities, including the outcome of these examinations, it is possible that the amount paid upon resolution of issues raised may differ from the
amount provided. Differences between the reserves for tax contingencies and the amounts owed by us are recorded in the period they become known. The ultimate outcome of these tax contingencies could have a material effect on our financial position,
results of operations or cash flows.

Our stock price may be volatile.

Historically, the market for technology stocks has been extremely volatile. Our common stock has experienced, and may continue to experience, substantial price volatility. The occurrence of any one or more of the
factors noted above could cause the market price of our common stock to fluctuate. In addition, the following factors could cause the market price of our common stock to fluctuate:



| |  |  | loss of a major customer;
| | - |  | -------------------------



| |  |  | significant changes or slowdowns in the funding and spending patterns of our current and prospective customers;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | the addition or departure of key personnel;
| | - |  | -------------------------------------------



| |  |  | variations in our quarterly operating results;
| | - |  | ----------------------------------------------



| |  |  | announcements by us or our competitors of significant contracts, new products or product enhancements;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | failure by us to meet product milestones;
| | - |  | -----------------------------------------



| |  |  | acquisitions, distribution partnerships, joint ventures or capital commitments;
| | - |  | -------------------------------------------------------------------------------



| |  |  | regulatory changes in telecommunications;
| | - |  | -----------------------------------------



| |  |  | variations between our actual results and the published expectations of securities analysts;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | changes in financial estimates by securities analysts;
| | - |  | ------------------------------------------------------



| |  |  | sales of our common stock or other securities in the future;
| | - |  | ------------------------------------------------------------



| |  |  | changes in market valuations of networking and telecommunications companies;
| | - |  | ----------------------------------------------------------------------------



| |  |  | fluctuations in stock market prices and volumes and;
| | - |  | ----------------------------------------------------



| |  |  | announcements or implementation of any capital restructure i.e. stock buyback or cash distribution.
| | - |  | ---------------------------------------------------------------------------------------------------

In addition, the stock market in general, and the NASDAQ Stock Market and technology companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating performance of such companies. These broad market and industry factors may materially adversely affect the market price of our common stock, regardless of our actual
operating performance. In the past, following periods of volatility in the market price of a companys securities, securities class action litigation has often been instituted against such companies.

Significant insider ownership, provisions of our charter documents and provisions of Delaware law may limit shareholders ability to influence key transactions,
including changes of control.

As of July 31, 2008, our officers, directors and entities affiliated with them, in the aggregate,
beneficially owned approximately 34% of our outstanding common stock. These stockholders, if acting together, would be able to significantly influence matters requiring approval by our stockholders, including the election of directors



23

and the approval of mergers or other business combination transactions. In addition, provisions of our amended and restated certificate of incorporation,
by-laws, and Delaware law could make it more difficult for a third party to acquire us, even if doing so would be beneficial to certain stockholders.

IPO Allocation Case

Beginning on July 2, 2001, several purported class action complaints were filed in the United States District Court for the
Southern District of New York against the Company and several of its officers and directors (the Individual Defendants) and the underwriters for the Companys initial public offering on October 21, 1999. Some of the complaints
also include the underwriters for the Companys follow-on offering on March 14, 2000. An amended complaint, which is the operative complaint, was filed on April 19, 2002 on behalf of persons who purchased the Companys common
stock between October 21, 1999 and December 6, 2000. The amended complaint alleges claims against the Company, several of the Individual Defendants and the underwriters for violations under Sections 11 and 15 of the Securities Act of 1933,
as amended (the Securities Act), primarily based on the assertion that the Companys lead underwriters, the Company and several of the Individual Defendants made material false and misleading statements in the Companys
Registration Statements and Prospectuses filed with the Securities and Exchange Commission, or the SEC, in October 1999 and March 2000 because of the failure to disclose (a) the alleged solicitation and receipt of excessive and undisclosed
commissions by the underwriters in connection with the allocation of shares of common stock to certain investors in the Companys public offerings and (b) that certain of the underwriters allegedly had entered into agreements with
investors whereby underwriters agreed to allocate the public offering shares in exchange for which the investors agreed to make additional purchases of stock in the aftermarket at pre-determined prices. It also alleges claims against the Company,
the Individual Defendants and the underwriters under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), primarily based on the assertion that the Companys lead underwriters, the Company
and the Individual Defendants defrauded investors by participating in a fraudulent scheme and by making materially false and misleading statements and omissions of material fact during the period in question. The amended complaint seeks damages in
an unspecified amount.

The action against the Company is being coordinated with approximately three hundred other nearly identical actions
filed against other companies. Due to the large number of nearly identical actions, the court has ordered the parties to select up to twenty test cases. To date, along with sixteen other cases, the Companys case has been selected
as one such test case. As a result, among other things, the Company will be subject to broader discovery obligations and expenses in the litigation than non-test case issuer defendants.

On October 9, 2002, the court dismissed the Individual Defendants from the case without prejudice.
This dismissal disposed of the Section 15 and Section 20(a) claims without prejudice, because these claims were asserted only against the Individual Defendants. On October 13, 2004, the court denied the certification of a class in the
action against the Company with respect to the Section 11 claims alleging that the defendants made material false and misleading statements in the Companys Registration Statement and Prospectuses. The certification was denied because no
class representative purchased shares between the date of the IPO and January 19, 2000 (the date unregistered shares entered the market), and thereafter suffered a loss on the sale of those shares. The court certified a class in the action
against the Company with respect to the Section 10(b) claims alleging that the Company and the Individual Defendants defrauded investors by participating in a fraudulent scheme and by making materially false and misleading statements and
omissions of material fact during the period in question. On December 5, 2006, the Second Circuit vacated the district courts class certification decision. On April 6, 2007, the Second Circuit panel denied a petition for rehearing
filed by the plaintiffs, but noted that the plaintiffs could ask the district court to certify a more narrow class than the one that was rejected.

Prior to the Second Circuits December 5, 2006 ruling, a majority of the issuers, including the Company, and their insurers had submitted a settlement agreement to the district court for approval. In light of the Second Circuit
opinion, the parties agreed that the settlement could not be approved. On June 25, 2007, the district court approved a stipulation filed by the plaintiffs and the issuers terminating the proposed settlement. On August 14, 2007, the
plaintiffs filed a Second Amended Class Action complaint against the Company. The amended complaint contains a number of changes, including changes to the definition of the purported class of investors, and the elimination of the Individual
Defendants as defendants. The Company and the underwriters filed separate motions to dismiss the amended complaint on November 14, 2007. On March 26, 2008, the Court denied the motion to dismiss the Section 10(b) claims but dismissed
certain Section 11 claims against the Company. On June 5, 2008, the Court dismissed the remaining Section 11 claims against the Company in response to a motion for partial reconsideration. On September 27, 2007, the plaintiffs
filed a motion for class certification in the Companys case. On December 21, 2007, the Company and the underwriters filed papers opposing class certification. On March 28, 2008, Plaintiffs filed their reply brief in support of their
motion for class certification. We are awaiting the District Courts decision on the motion for class certification.

The Company
cannot predict whether the parties will be able to negotiate a revised settlement that complies with the standards set out in the Second Circuits decision. Due to the inherent uncertainties of litigation, the Company cannot accurately predict
the ultimate outcome of the matter. If the parties are not able to renegotiate a settlement and the Company is found liable, the Company is unable to estimate or predict the potential damages that might be awarded, whether such damages would be
greater than the Companys insurance coverage, and whether such damages would have a material impact on our results of operations or financial condition in any future period.

Derivative Lawsuits

On May 31,
2006, a purported shareholder derivative action, captioned Weisler v. Barrows (Weisler), was filed in the United States District Court for the District of Delaware (the Delaware Court), on the Companys behalf, against
it as nominal defendant, the Companys Board of Directors and certain of its current and former officers (as amended on October 4, 2006). The plaintiff derivatively claims, among other things, violations of Section 14(a) of the
Securities Exchange Act of 1934, Section 304 of the Sarbanes-Oxley Act of 2002, and breaches of fiduciary duty by the defendants in connection with the Companys historical stock option granting practices. The plaintiff seeks unspecified
damages, profits, the return of compensation paid by the Company, an injunction and costs and attorneys fees. Substantially similar actions, captioned Vanpraet v. Deshpande (Vanpraet) and Patel v. Deshpande (Patel),
were filed in the United States District Court for the District of Massachusetts on June 28, 2006 and July 13, 2006, respectively (the Massachusetts Court), and Ariel v. Barrows (Ariel) was filed on July 21,
2006 in the United States District Court for the Eastern District of New York (the New York Court). None of the plaintiffs made presuit demand on the Companys Board of Directors

prior to filing suit. By Memorandum and Order dated November 6, 2006, the Delaware Court transferred Weisler to the District of Massachusetts. By
stipulation of the parties, on November 21, 2006, the New York Court transferred Ariel to the District of Massachusetts. By margin order dated May 24, 2007, the Massachusetts Court consolidated Weisler, Vanpraet, Patel and Ariel (the
Federal Action). Subsequent to that consolidation, plaintiffs in the Federal Action served a demand letter on the Company, which has since been refused. Proceedings in the Federal Action are currently stayed. The Federal Action does not
seek affirmative relief from the Company.

On September 19, 2006, an additional purported shareholder derivative action, captioned
McMahon v. Smith, was filed in the Middlesex Superior Court for the Commonwealth of Massachusetts, on the Companys behalf, against it as nominal defendant, the Companys Board of Directors and certain of its current and former officers.
The plaintiff derivatively claims, among other things, breaches of fiduciary duty by the defendants in connection with the Companys historical stock option granting practices, and also that certain defendants misappropriated confidential
Company information for personal profit by selling Company stock while in possession of material, non-public information. The plaintiff sought unspecified damages, profits, an injunction and costs and attorneys fees. The plaintiff did not make
presuit demand on the Companys Board of Directors prior to filing suit. An amended complaint was filed on July 16, 2007 which also named additional officers of the Company as defendants. On August 15, 2007, the defendants filed a
motion to dismiss and on November 19, 2007, the court heard oral arguments on that motion. By a Memorandum and Order dated March 6, 2008, the Court granted the defendants motion and dismissed the case with prejudice and without leave
to file a further amended complaint. The plaintiff did not appeal that decision. The purported derivative action did not seek affirmative relief from the Company.

In October 2007, a purported Sycamore Networks, Inc. shareholder filed a complaint for violation of Section 16 of the Securities Exchange Act of 1934, which prohibits short-swing trading against the
Companys Initial Public Offering underwriters. The complaint, Vanessa Simmonds v. Morgan Stanley, et al., in District Court for the Western District of Washington seeks recovery of short-swing profits. On April 28, 2008, the district
court established a briefing schedule for motions to dismiss and ruled that all discovery be stayed pending resolution of the motions to dismiss. On July 25, 2008, the Company and the Initial Public Offering underwriters filed motions to
dismiss the complaint. The Company is named as a nominal defendant. No recovery is sought from the Company in this matter.

Other
Matters

On or about July 9, 2008, the Commissioners of the Securities and Exchange Commission (the SEC) authorized the
final settlement between the Company and the SEC in connection with the previously disclosed investigation into the Companys historical stock option granting practices and related accounting. Without admitting or denying the allegations in the
SECs complaint, the Company agreed to settle the charges by consenting to a permanent injunction against any future violations of the federal securities laws. No monetary penalties were assessed against the Company in conjunction with the
settlement. This settlement concludes the SECs investigation into the Companys historical stock option granting practices and related accounting.

On June 29, 2006, a former employee of the Company filed a complaint in Massachusetts Superior Court alleging, among other things, claims relating to wrongful termination of an employment agreement, fraud in the
inducement, retaliation and claims relating to certain of the Companys stock option grant practices in 1999-2001. The complaint demanded lost wages, unspecified monetary damages and reinstatement of medical benefits, among other things. The
case was moved to the Business Litigation Session of the Suffolk County Superior Court and, following an oral hearing on a motion to dismiss, the case was ordered dismissed on January 24, 2007. The plaintiff has filed a Notice of Appeal of the
order and judgment.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis should be read in conjunction with Item 6.Selected Financial Data and our consolidated financial
statements and the related notes thereto included elsewhere in this report. Except for the historical information contained herein, we wish to caution you that certain matters discussed in this report constitute forward-looking statements that
involve risks and uncertainties. Our actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including, without limitation, those risks and uncertainties discussed under the
heading Item 1A.Risk Factors contained in this Form 10-K and any other reports filed by us from time to time with the Securities and Exchange Commission. We disclaim any intention or obligation to update or revise any
forward-looking statements, whether as a result of new information, future results or otherwise. Forward-looking statements include statements regarding our expectations, beliefs, intentions or strategies regarding the future and can be identified
by forward-looking words such as anticipate, believe, could, estimate, expect, intend, may, should, will, and would or similar
words.

Executive Summary

We
develop and market intelligent bandwidth management solutions for fixed line and mobile network operators worldwide and provide services associated with such products. Our current and prospective customers include domestic and international wireline
and wireless network service providers, utility companies, multiple systems operators (MSOs) and government entities with private fiber networks (collectively referred to as service providers). Our comprehensive portfolio of optical
switches, multiservice access platforms, and industry-leading networking software extends across the network, from multiservice access and regional backhaul to the optical core. We believe that our products enable network operators to efficiently
and cost-effectively provision and manage multiservice access and optical network capacity to support a wide range of converged services such as voice, video and data.

Total revenue for fiscal 2008 was $115.5 million, a decrease of 26% compared to fiscal 2007. Total revenue for fiscal 2007 was $156.0 million, an increase of 79% compared to fiscal 2006. Our net loss for fiscal 2008
was $0.1 million compared to a net loss for fiscal 2007 of $13.2 million. The net loss for fiscal 2008 includes asset impairment charges of $4.4 million. The net loss for fiscal 2007 includes acquisition related charges of $12.4 million for
in-process research and development and asset impairment charges of $17.3 million. We continue to maintain a significant cost structure, relative to our revenue, particularly within the research and development organization. We believe that these
investments are necessary to advance our technology and secure new business.

As we remain focused on improvements in our business, our
management and Board of Directors will continue to consider strategic options that may serve to maximize shareholder value. These options include acquiring or making strategic investments in companies with either complementary technologies or in
adjacent markets to add complementary products and services, expand the markets we serve and diversify our customer base.

Our total cash,
cash equivalents and investments were $941.8 million at July 31, 2008. Included in this amount were cash and cash equivalents of $499.9 million. We intend to fund our operations, including fixed commitments under operating leases, and any
required capital expenditures for the foreseeable future using our existing cash, cash equivalents and investments. We believe that, based on our business plans and current conditions, our existing cash, cash equivalents and investments will be
sufficient to satisfy our anticipated cash requirements for the next twelve months. We also believe that our current cash, cash equivalents and investments will enable us to pursue the strategic options discussed above.

As of July 31, 2008, Sycamore and its subsidiaries employed approximately 492 persons, which was a net increase of 66 persons from the approximately
426 persons employed on July 31, 2007.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements. The preparation of
these financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires us to make judgments, assumptions and estimates that affect the reported amounts of assets,
liabilities, revenue and expenses and disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those relating to revenue recognition, allowance for doubtful accounts, investments, warranty
obligations, inventory valuation, litigation and other contingencies, intangible assets and goodwill and share-based compensation expense. Estimates are based on our historical experience and other assumptions that we consider reasonable under the
circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Differences between our
estimates and the actual results are reflected in the results of operations for the period in which the estimate is changed.

We believe
that the following critical accounting policies affect the most significant judgments, assumptions and estimates we use in preparing our consolidated financial statements. Changes in these estimates can affect materially the amount of our reported
net income or loss.

Revenue Recognition

The Companys products enable network operators to efficiently and cost-effectively provision and manage multiservice access and optical capacity to support a wide range of converged services such as voice, video and data. As our
customer requirements have been evolving, the software component of our product is becoming more than incidental to its functionality. Accordingly, for such arrangements where software is more than incidental to the functionality of the product, the
Company recognizes revenue pursuant to the requirements of Statement of Position (SOP) 97-2 Software Revenue Recognition, issued by the American Institute of Certified Public Accountants, as amended by SOP 98-9 Modification of
SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions. The Company will apply the provisions of SOP 97-2, as amended, to substantially all of its customer arrangements beginning in the first quarter of fiscal 2009.

In accordance with SOP 97-2, the Company begins to recognize revenue when all of the following criteria are met: the Company has evidence
of an arrangement with a customer; the Company delivers the products; agreement terms are deemed fixed or determinable and free of contingencies or uncertainties; and collection is probable. Evidence of an arrangement generally consists of sales
contracts or agreements and customer purchase orders. Product delivery occurs when title and risk of loss are transferred to the customer. If uncertainties exist regarding customer acceptance, the company recognizes revenue when all uncertainties
are resolved. The Company assesses whether the sales price is fixed or determinable based on payment terms and whether the sales price is subject to refund or adjustment. Collectibility is assessed based on the creditworthiness of the customer as
determined by credit checks and the customers payment history to the Company.

For arrangements which include the delivery of
multiple elements, revenue is allocated for all elements based on vendor-specific objective evidence, or VSOE, of fair value. VSOE is generally the price charged when that element is sold separately or the price is established by management having
the relevant authority.

In situations where VSOE exists for all elements (delivered and undelivered), the Company allocates the total
revenue to be earned under the arrangement among the various elements, based on their relative fair value. For transactions where VSOE exists only for the undelivered elements, the Company uses the residual method and defers the full fair value of
the undelivered elements and recognizes the difference between the total arrangement fee and the amount deferred as revenue. If VSOE does not exist for undelivered items that are services, then the entire arrangement fee is recognized ratably over
the remaining service period. If VSOE does not exist for undelivered elements that are specified products or features, all revenue is deferred until the earlier of the delivery of all elements or the point at which VSOE for the undelivered elements
is determined.

##### Table of Contents

Revenue from installation or other services is recognized as work is performed or ratably over the
service period.

For arrangements in which the software component is incidental to the functionality of the product, the Company has
recognized revenue in accordance with Staff Accounting Bulletin (SAB) No. 104, Revenue Recognition, which states that revenue is realized or realizable and earned when all of the following criteria are met: persuasive
evidence of an arrangement exists; delivery has occurred or services have been rendered; the price to the buyer is fixed or determinable; and collectibility is reasonably assured. In instances where final acceptance of the product, system, or
solution is specified by the customer, revenue is deferred until all acceptance criteria have been met.

For arrangements in which the
software component is incidental to the functionality of the product and that involve the delivery or performance of multiple elements, the determination as to how the arrangement consideration should be measured and allocated to the separate
deliverables of the arrangement has been determined in accordance with EITF 00-21, Revenue Arrangements with Multiple Deliverables. When an arrangement involves multiple elements, the entire fee from the arrangement is allocated to each
respective element based on its relative fair value and recognized when revenue recognition criteria for each element are met. Fair value for each element is established based on the sales price charged when the same element is sold separately. If
fair value does not exist for any undelivered element, revenue is not recognized until the earlier of (i) the delivery of the undelivered element or (ii) fair value of the undelivered element exists, unless the undelivered element is a
service, in which case revenue is recognized as the service is performed once the service is the only undelivered element.

Allowance for Doubtful
Accounts

The allowance for doubtful accounts is based on our assessment of the collectibility of specific customer accounts. In the
event that we become aware of deterioration in a particular customers financial condition, a review is performed to determine if additional provisions for doubtful accounts are required.

Investments

We account for our marketable securities
in accordance with SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities (SFAS No. 115). Our investments are classified as available-for-sale and are recorded at fair value with any
unrealized gain or loss recorded as an element of stockholders equity. The fair value of investments is determined based on quoted market prices at the reporting date for those instruments. We evaluate our investments for potential impairment
on a quarterly basis and would recognize an impairment charge should a decline in the fair value of investments below the related cost basis be judged to be other-than-temporary. We consider various factors in determining whether to recognize an
impairment charge, including the length of time and extent to which the fair value has been less than our cost basis, the financial condition and near-term prospects of the investee, and our intent and ability to hold the investment for a period of
time sufficient to allow for any anticipated recovery in market value.

Warranty Obligations

We accrue for warranty costs at the time revenue is recognized based on contractual rights and on the historical rate of claims and costs to provide
warranty services. If we experience a change in warranty claims that vary from historical experience in our costs to provide warranty services, we may be required to adjust our warranty accrual. A change in the warranty accrual will impact our gross
margin.

Inventory

We continuously
monitor inventory balances and record inventory provisions for any excess of the cost of the inventory over its estimated market value, based on assumptions about future demand, manufacturing quantities and market conditions. While such assumptions
may change from period to period, we measure the net realizable value of inventories using the best information available as of the balance sheet date. If actual market

##### Table of Contents

conditions are less favorable than those projected, or we experience a higher incidence of inventory obsolescence because of rapidly changing technology and
customer requirements, additional inventory provisions may be required. Once inventory has been written down to its estimated net realizable value, its carrying value can not be increased due to subsequent changes in demand forecasts. Accordingly,
if inventory previously written down to its net realizable value is subsequently sold, gross profit margins would be favorably impacted.

Reserve for
Contingencies

We are subject to various claims, litigation and other disputes, as well as potential liabilities associated with various
tax matters. Periodically, we review the status of each significant matter and assess our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue a
liability for the estimated loss. Because of uncertainties related to these matters, accruals, if any, are based only on the most current and dependable information available at any given time. As additional information becomes available, we may
reassess the potential liability from pending claims, litigation and tax matters and the probability of claims being successfully asserted against us. As a result, it may be necessary to revise our estimates related to these pending claims,
litigation and other disputes and potential liabilities associated with various tax matters. Such revisions in the estimates of the potential liabilities are reflected in our results of operations in the period of change and could have a material
impact on our consolidated results of operations, financial position and cash flows in the future.

Goodwill

As of July 31, 2008, the consolidated balance sheet included $20.3 million in goodwill. This amount primarily represents the remaining excess of
the total purchase price of the Eastern Research acquisition over the fair value of the net assets acquired. In accordance with SFAS 142, the Company tests goodwill for impairment on an annual basis, which we have determined to be the last business
day of June each year, and between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. There was no impairment of goodwill in fiscal 2008 or
2007.

Intangible Assets

As of
July 31, 2008, the consolidated balance sheet included $4.0 million in other intangible assets, net. The Company accounts for the impairment or disposal of intangible assets in accordance with the provisions of SFAS 144. In accordance with
SFAS 144, each intangible asset is tested for impairment whenever events or changes in circumstances indicate that the assets carrying amount may not be recoverable. Valuation of our intangible assets requires the Company to make assumptions
about the estimates of future cash flows, including assumptions related to revenue, operating income, asset related expenditures, working capital levels and other factors. If actual market conditions differ or the estimates change, the Company may
be required to record additional impairment charges in future periods. Such charges would have the effect of decreasing earnings or increasing losses in such period.

During the first quarter of fiscal 2007, the Company decided to discontinue the development of its acquired OX8000 product, resulting in an asset impairment charge of $6.6 million. In the fourth quarter of fiscal
2007, the Company decided to cease further development of its acquired BSG product. As a result, the Company recorded an asset impairment charge of $10.7 million. During the fourth quarter of 2008, the Company incurred an intangible asset impairment
charge of $4.4 million related to the acquired DNX technology and customer relationships. The impairment charge was primarily related to lower than previously estimated revenues from our DNX products.

Share-Based Compensation Expense

We account for
share-based compensation expense in accordance with SFAS 123R, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. We have
estimated the fair value of share-based options on the date of grant using the Black Scholes pricing model, which is affected by our stock price as well as assumptions

regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the term of the awards, actual and
projected employee option exercise behaviors, risk free interest rate and expected dividends. We are also required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those
estimates.

Total revenue decreased in fiscal 2008 compared to fiscal 2007. Product revenue consists primarily
of sales of our intelligent bandwidth management solutions. Product revenue decreased in fiscal 2008 compared to fiscal 2007 primarily due to a significant decline in the level of orders from a major customer. Service revenue consists primarily of
fees for services relating to the maintenance of our products, installation services and training. Service revenue increased in fiscal 2008 compared to fiscal 2007 primarily due to the inclusion of service revenue from our access products for the
entire current fiscal year compared to a partial year in fiscal 2007 and increased core product installation services in fiscal 2008 compared to fiscal 2007.

For fiscal 2008, two customers accounted for 23% and 22% of revenue, or a combined 45% of our total revenue. Two customers accounted for 53% and 16% of revenue in fiscal 2007, or a combined 69% of our total revenue.
International revenue represented 48% of revenue in fiscal 2008, compared to 27% of revenue in fiscal 2007. We expect future revenue will continue to be highly concentrated in a relatively small number of customers. The timing of customer
deployments in any given quarter may cause shifts in both the number of greater than 10% customers and in the percentage mix of domestic and international revenue. The loss of any one of these customers or any substantial reduction or delay in
orders by any one of these customers could materially adversely affect our business, financial condition and results of operations.

##### Table of Contents

Product gross profit

Cost of product revenue consists primarily of amounts paid to third-party contract manufacturers for purchased materials and services and other internal manufacturing costs. Product gross profit decreased in fiscal
2008 compared to fiscal 2007. The decrease was primarily due to reduced revenue in fiscal 2008 caused by a decline in the level of orders from a major customer, and an inventory provision of $3.7 million booked in fiscal 2008. Product gross profit
percentage increased in fiscal 2008 compared to fiscal 2007 primarily due to a shift in customer product mix. Product gross profit may fluctuate from period to period due to revenue fluctuation, volume, pricing pressures resulting from intense
competition in our industry as well as the enhanced negotiating leverage of certain larger customers. In addition, product gross profit may be affected by changes in the mix of products sold, channels of distribution, overhead absorption, sales
discounts, increases in labor costs, excess inventory and obsolescence charges, increases in component pricing or other material costs, the introduction of new products or the entry into new markets with different pricing and cost structures.

Service gross profit

Cost of service
revenue consists primarily of costs of providing services under customer service contracts which include salaries and related expenses and other fixed costs. Service gross profit remained consistent in fiscal 2008 compared to fiscal 2007. Service
gross profit percentage decreased in fiscal 2008 compared to fiscal 2007 primarily due to a change in the mix of customers and services provided, namely a higher level of installation services, which are at a lower margin, versus maintenance
services. As most of our service cost of revenue is fixed, increases or decreases in revenue will have a significant impact on service gross profit. Service gross profit may be affected in future periods by various factors including, but not limited
to, the change in mix between technical support services and advanced services, competitive and economic pricing pressures, the enhanced negotiating leverage of certain larger customers, maintenance contract renewals and the timing of renewals.

Research and Development Expenses

Research and development expenses consist primarily of salaries and related expenses and prototype costs relating to design, development, testing and
enhancements of our products. Research and development expenses increased in fiscal 2008 compared to fiscal 2007. The increase was primarily due to increased project related costs, including the expansion of our development center in Shanghai. We
continue to focus our research and development investments on features and functionality targeted at existing and prospective customer requirements. We are continuing to invest in R&D with a view toward convergence and the next generation of
optical products to support it. We believe that investment in both domestic and off-shore R&D initiatives will provide a portfolio of products to address an evolving market allowing us to compete more effectively for both near and longer term
opportunities.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of salaries, commissions and related expenses, amortization of customer evaluation inventory and other sales and marketing support expenses. Sales and marketing expenses
decreased in fiscal 2008 compared to fiscal 2007. The decrease was primarily due to (1) higher costs in fiscal 2007 associated with personnel costs and an employment agreement between the Company and a former Company executive which resulted in
a non-cash charge of $1.5 million arising from the modification of his stock option agreement and (2) lower commissions in fiscal 2008 due to lower order levels in fiscal 2008 compared to fiscal 2007. Within our existing spending levels, we
continue to allocate sales and marketing resources to those geographic regions where we see the most attractive opportunities.

General and
Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses for executive, finance
and administrative personnel, professional fees and other general corporate purposes. General and administrative expenses decreased in fiscal 2008 compared to fiscal 2007. The decrease was primarily due to lower costs associated with the Audit
Committees stock option and related accounting investigation. In fiscal 2008 and 2007 we recorded expenses of approximately $1.4 million and $12.0 million, respectively, in connection with the Audit Committees investigation.

Asset Impairments

We evaluate goodwill and
intangible assets for impairment annually and when events occur or circumstances change that may reduce the value of the asset below its carrying amount using forecasts of discounted future cash flows. In fiscal 2007, we decided to discontinue the
development of our OX8000 product. This product was in the development stage on the date of its acquisition and accordingly we recorded in-process research and development expense of $12.4 million on the date of the acquisition. As a result of our
decision to discontinue the OX8000 product, we recorded an asset impairment charge of $6.6 million in the first quarter of 2007. The charge related to certain tangible and intangible assets associated with the product, specifically customer
relationships and other related fixed assets. In addition, we recorded a charge of $1.1 million related to OX8000 inventory in cost of product revenue.

In the fourth quarter of fiscal 2007, the Company decided to cease further development and marketing of our acquired BSG product. As a result of the Companys decision to cease development and marketing of the
BSG product, we recorded an asset impairment charge of $10.7 million in the fourth quarter of fiscal 2007. The charge related to certain tangible and intangible assets associated with the BSG product, specifically technology and customer
relationships and other related fixed assets. In addition, the Company recorded a charge of $0.3 million related to BSG inventory in cost of product revenue.

In the fourth quarter of fiscal 2008, the Company assessed the carrying value of its remaining intangible assets pursuant to SFAS 144. As a result, the Company recorded an impairment charge of $4.4 million related to
previously acquired intangible assets associated with DNX technology and customer relationships.

In-process Research and Development

In the first quarter of fiscal 2007, we recorded in-process research and development expense of $12.4 million which was charged to expense because
technological feasibility had not been established and no future alternative uses for the acquired technology existed at the time of acquisition. The estimated fair value of the purchased in-process research and development was determined using a
discounted cash flow model, based on a discount rate which took into consideration the stage of completion and risks associated with developing the technology.

Restructuring and Related Impairments

During the first quarter of 2008, we completed a consolidation of our Moorestown, New Jersey facility and recorded a restructuring charge of $2.0 million.
This consolidation was completed in conjunction with the decision in the fourth quarter of fiscal 2007 to reduce our workforce by 46 employees across the Company. We completed these actions to better align development resources with future growth
opportunities, further improve operational efficiencies, and capitalize on additional acquisition synergies. As a result of these actions, we recorded a restructuring charge related to rent and other facility charges related to our Moorestown
facility. The charge in first quarter of fiscal 2008 also includes severance costs related to several employees affected by the fourth quarter fiscal 2007 workforce reduction who were placed on transition programs and whose employment was terminated
in the first quarter of fiscal 2008. In the third quarter of fiscal 2008 we recorded an additional restructuring charge related to the consolidation of our Moorestown facility of $0.4 million. The charge was based on a revised lower estimate of
future sublease income and a lease termination fee. It is possible that such actions may be necessary in the future should market and business conditions change.

Reserve for Contingencies

In accordance with SFAS No. 5, a liability is recorded when it is both probable that a
liability has been incurred and the amount of the loss can be reasonably estimated. The Company reviews the need for any such provision on a quarterly basis and records any necessary adjustments to reflect the effect of ongoing negotiations,
settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case in the period they become known. We are also subject to tax audits by various tax authorities. Based on ongoing negotiations and
settlement discussions with various tax authorities in 2007, the Company decreased this accrual by $2.2 million, resulting in a reduction of expenses in fiscal 2007. The Company has recorded its best estimate of the probable liability resulting from
the ultimate outcome of these audits as of July 31, 2008. While we believe that the amounts accrued are adequate, any subsequent change in our estimates will be recorded at such time the change is probable and estimable.

Interest and other income, net decreased in fiscal 2008 compared to fiscal 2007. The decrease was
primarily due to lower interest rates.

Income Tax Expense

Income tax expense of $0.6 million was recorded in fiscal 2008 versus $0.9 million in fiscal 2007.

As a
result of incurring substantial net operating losses from 2001 through 2005 and in 2007, we determined that it is more likely than not that our deferred tax assets may not be realized. Therefore, in accordance with the requirements of FASB 109, we
maintain a full valuation allowance. If we generate sustained future taxable income against which these tax attributes may be applied, some or all of the valuation allowance would be reversed. If the valuation allowance were reversed, a portion
would be recorded as an increase to paid-in capital, a reduction to goodwill and the remainder would be recorded as a reduction in income tax expense.

Total revenue increased in fiscal 2007 compared to fiscal 2006. The increase was due to an
increase in both product revenue and service revenue. Our multiservice access products, acquired on September 6, 2006 through the acquisition of Eastern Research, contributed approximately $29.1 million to product revenue for fiscal 2007.
Product revenue increased in fiscal 2007 compared to fiscal 2006 primarily due to a higher level of orders from our existing customers to increase the capacity of their networks and the revenue contribution from our newly acquired multiservice
access products. Service revenue increased in fiscal 2007 compared to fiscal 2006 primarily due to service revenue from our newly acquired multiservice access business and a higher base of maintenance renewal contracts.

For fiscal 2007, two customers accounted for 53% and 16% of revenue or 69% of our total revenue. Three customers accounted for 43%, 26% and 19% of
revenue in fiscal 2006 or 88% of our total revenue. International revenue represented 27% of revenue in fiscal 2007, compared to 67% of revenue in fiscal 2006.

Product gross profit

Product gross profit percentage decreased in fiscal 2007 compared to fiscal 2006. The decrease was primarily the result of a $3.8 million purchase accounting step up charge related to acquired inventory, a $1.4
million charge related to inventory of Eastern Researchs OX8000 and BSG products which the Company decided to discontinue, and unfavorable product and customer mix, partially offset by higher margins from our newly acquired multiservice access
business.

Service gross profit

Service gross profit increased in fiscal 2007 compared to fiscal 2006. The increase was primarily due to increased maintenance revenues.

Research and Development Expenses

Research and development expenses increased in fiscal 2007 compared to fiscal 2006. The increase was primarily due to the acquisition of Eastern Research,
which contributed additional research and development expenses.

Sales and Marketing Expenses

Sales and marketing expenses increased in fiscal 2007 compared to fiscal 2006. The increase was primarily due to the acquisition of Eastern Research,
which contributed additional sales and marketing expenses and the costs associated with an employment agreement between the Company and the Companys former Vice President of Worldwide Sales and Support and a resulting charge arising from the
modification of his stock option agreement which was recorded in the first quarter of fiscal 2007.

General and Administrative Expenses

General and administrative expenses increased in fiscal 2007 compared to fiscal 2006. The increase was primarily due to costs of approximately $12.0
million associated with the Audit Committees independent stock option investigation, $4.3 million of amortization expense related to purchased intangibles and the acquisition of Eastern Research, which contributed additional general and
administrative expenses.

Asset Impairments

Asset impairment charges of $17.3 were recorded in fiscal 2007 and related to the decision to discontinue the development of Eastern Researchs OX8000 product in the first quarter of fiscal 2007 as well as the decision to cease
development and marketing of the BSG product in the fourth quarter of fiscal 2007.

In-process Research and Development

In-process research and development of $12.4 million was written-off in the first quarter of fiscal 2007 and related to a project under development for
which technological feasibility had not been established and no future alternative uses for the technology existed at the time of acquisition.

Restructuring Charges

During the fourth quarter of fiscal 2007, the Company reduced its workforce by 46 employees to better
align development resources with future growth opportunities, further improve operational efficiencies, and capitalize on additional acquisition synergies. As a result of these actions, the Company recorded a restructuring charge of $1.5 million
that was comprised primarily of expenses related to the workforce reduction.

Litigation Settlement

In the second quarter of fiscal 2006, we entered into an Agreement of Settlement and Release to resolve a 2003 lawsuit that had been filed by a component supplier to a company that we acquired. Under the terms of the
agreement, the Company paid the supplier $1.0 million and the parties filed a stipulation of dismissal with prejudice in the underlying lawsuit. In the second quarter of fiscal 2006 we recorded $0.8 million as an operating expense with the remainder
being charged to our existing reserve for contingencies.

Reserve for Contingencies

During the fourth quarter of fiscal 2006, the Company accrued $6.8 million associated with contingencies related to claims, litigation and other disputes,
as well as potential liabilities associated with various tax matters. Based on ongoing negotiations and settlement discussions, the Company decreased this accrual by $2.2 million during the fourth quarter of fiscal 2007.

Interest and other income, net increased for fiscal 2007 compared to fiscal 2006. The increase was
primarily due to higher interest rates.

Income Tax Expense

Income tax expense of $0.9 million was recorded in fiscal 2007 for alternative minimum tax and taxes due on income generated in foreign tax jurisdictions and certain states. We did not record any net tax benefits
relating to our net losses due to the uncertainty surrounding the realization of these future tax benefits.

Liquidity and Capital Resources

Year Ended July 31, 2008

Total cash, cash equivalents and investments were $941.8 million at July 31, 2008. Included in this amount were cash and cash equivalents of $499.9 million, compared to $249.3 million at July 31, 2007. The increase in cash and
cash equivalents of $250.6 million was attributable to cash provided by investing activities of $222.0 million, cash provided by operating activities of $17.7 million and cash provided by financing activities of $10.9 million.

Net cash provided by investing activities was $222.0 million and consisted primarily of net maturities of investments of $233.9 million offset by
purchases of property and equipment of $11.9 million.

Net cash generated by operating activities was $17.7 million. Net loss was $0.1
million and included non-cash charges including share-based compensation of $4.5 million, an inventory provision of $3.7 million, restructuring charges of $1.1 million, depreciation and amortization of $12.8 million, asset impairment charges of $4.4
million and a loss on the disposal of a fixed asset of $54 thousand. Accounts receivable decreased to $8.8 million at July 31, 2008 from $30.5 million at July 31, 2007. The decrease was primarily due to a decrease in sales due to a
significant decline in the level of orders from one major customer. Our accounts receivable and days sales outstanding are impacted primarily by the timing of shipments, collections performance and timing of support contract renewals. Inventory
levels increased to $23.8 million at July 31, 2008 from $21.7 million at

##### Table of Contents

July 31, 2007. The increase was primarily due to the timing of shipments. Deferred revenue increased to $19.1 million at July 31, 2008 from $14.4
million at July 31, 2007 primarily due to a $3.4 million increase in deferred product revenue. Accounts payable decreased to $2.5 million at July 31, 2008 from $13.6 million at July 31, 2007. Accrued expenses and other current
liabilities decreased to $10.8 million at July 31, 2008 from $28.5 million at July 31, 2007. The decrease is primarily due to settlement of three reserve contingencies totaling $14.7 million which was accrued in prior years.

For the year ended July 31, 2008, net cash provided by financing activities was $10.9 million and consisted of proceeds from the exercise of
employee stock options.

Our primary source of liquidity comes from our cash, cash equivalents and investments, which totaled $941.8
million at July 31, 2008. Our investments are classified as available-for-sale and consist of securities that are readily convertible to cash, including certificates of deposits and government securities. At July 31, 2008, $321.2 million
of investments with maturities of less than one year were classified as short-term investments. Based on our current expectations, we anticipate that some portion of our existing cash and cash equivalents and investments may be consumed by
operations. Our accounts receivable, while not considered a primary source of liquidity, represent a concentration of credit risk because the accounts receivable balance at any point in time typically consists of a relatively small number of
customer account balances. At July 31, 2008, more than 46% of our accounts receivable balance was attributable to five of our customers. In October 2007 we established a letter of credit in the amount of $6.6 million related to the settlement
of a reserve contingency; $3.3 million was paid in the second quarter of fiscal 2008 and the final $3.3 million payment was made in the third quarter of fiscal 2008. As of July 31, 2008, we do not have any other outstanding debt or credit
facilities, and do not anticipate entering into any debt or credit agreements in the foreseeable future. Our fixed commitments for cash expenditures consist primarily of payments under operating leases and inventory purchase commitments. We do not
currently have any material commitments for capital expenditures, or any other material commitments aside from operating leases for our facilities and inventory purchase commitments. We currently intend to fund our operations, including our fixed
commitments under operating leases, and any required capital expenditures using our existing cash, cash equivalents and investments.

As of
July 31, 2008, the future restructuring cash payments of $0.7 million consist primarily of amounts related to lease payments to be paid over the next three years.

Based on our current plans and business conditions, we believe that our existing cash and investments will be sufficient to satisfy our anticipated cash requirements for at least the next twelve months. We will
continue to consider appropriate action with respect to our cash position in light of the present and anticipated business needs as well as providing a means by which our shareholders may realize value in connection with their investment.

Year Ended July 31, 2007

Total cash, cash equivalents and investments were $924.8 million at July 31, 2007. Included in this amount were cash and cash equivalents of $249.3 million, compared to $169.8 million at July 31, 2006. The increase in cash and
cash equivalents of $79.5 million was attributable to cash provided in investing activities of $48.7 million, cash provided by operating activities of $28.0 million and cash provided by financing activities of $2.7 million.

Cash provided by investing activities of $48.7 million consisted primarily of net proceeds from maturities and sales of investments, offset by cash used
for the Eastern Research acquisition of $82.3 million and to a lesser extent purchases of property and equipment of $9.8 million. Cash provided by operating activities of $28.0 million consisted of net income for the period of $13.2 million,
adjusted for net non-cash charges totaling $47.7 million and offset by changes in working capital totaling $6.5 million. Net non-cash charges included depreciation and amortization, share-based compensation, adjustments to provisions for excess and
obsolete inventory, loss on disposal of equipment, in-process research and development and asset impairment charges.

The most significant changes in working capital were a decrease in accounts receivable of $10.2 million, a decrease in inventories of $6.3 million, decreases
in prepaids and other current assets and accrued restructuring costs and increases in deferred revenue, accounts payable and accrued expenses and other liabilities. Cash provided by financing activities of $2.7 million consisted of proceeds from
employee stock plan activity.

Commitments, Contractual Obligations and Off-Balance Sheet Arrangements

At July 31, 2008, our future contractual obligations, which consist of contractual commitments for operating leases and inventory and other purchase
commitments, were as follows (in thousands):

Payments made under operating leases will be accounted for as rent expense for the facilities
currently being utilized, or as a reduction of the restructuring liability for payments relating to excess facilities. Payments made for inventory purchase commitments will initially be capitalized as inventory, and will subsequently be charged to
cost of revenue as the inventory is sold or otherwise disposed of.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157 Fair Value Measurements, (SFAS 157). SFAS 157 defines fair value, establishes a
framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of SFAS 157 are effective for fiscal years beginning after November 15, 2007
and as a result, are effective for the Company in the first quarter of fiscal 2009. However, the FASB has recently approved a one year deferral for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial
statements on a nonrecurring basis. The Company has evaluated the potential impact of the SFAS 157 on its consolidated financial statements and has determined that the adoption of SFAS No. 157 is not expected to have a material effect on our
consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159,
The Fair Value Option for Financial Assets and Financial Liabilitiesincluding an amendment of FASB Statement No. 115 (SFAS 159). SFAS 159 expands the use of fair value accounting but does not affect existing
standards which require certain assets or liabilities to be carried at fair value. The objective of SFAS 159 is to improve financial reporting by providing companies with the opportunity to mitigate volatility in reported earnings caused by
measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. Under SFAS 159, a company may choose, at specified election dates, to measure eligible items at fair value and report unrealized gains
and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. SFAS 159 is effective for fiscal years beginning after November 15, 2007 and as a result, is effective for the Company in the
first quarter of fiscal 2009. The Company has evaluated the potential impact of SFAS 159 on its consolidated financial statements and has determined that the adoption of SFAS No. 159 is not expected to have a material effect on our consolidated
financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141(R), Business
Combinations (SFAS 141R). SFAS 141R replaces SFAS No. 141 and provides greater consistency in the accounting and financial reporting of business combinations. SFAS 141R requires the acquiring entity in a business combination
to recognize all assets acquired and liabilities assumed in the transaction, establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed, establishes principles and requirements for how an
acquirer recognizes and measures any non-controlling interest in the acquiree and the goodwill acquired, and

requires the acquirer to disclose the nature and financial effect of the business combination. Among other changes, this statement also requires that
negative goodwill be recognized in earnings as a gain attributable to the acquisition without first reducing other acquired assets, that acquisition-related costs are to be recognized separately from the acquisition and expensed as
incurred and that any deferred tax benefits resulting from a business combination are to be recognized in income from continuing operations in the period of the combination. SFAS 141R is effective for business combinations for which the acquisition
date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008 and as a result, is effective for the Company in the first quarter of fiscal 2010. The company is currently evaluating the potential
impact of SFAS 141R on its consolidated financial statement.

In April 2008, the FASB issued Staff Position (FSP) No. FAS
142-3, Determination of the Useful Life of Intangible Assets (FSP FAS 142-3). FSP FAS 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized
intangible asset under SFAS No. 142, Goodwill and Other Intangible Assets (SFAS 142). The intent of FSP FAS 142-3 is to improve the consistency between the useful life of a recognized intangible asset under SFAS 142 and the period
of expected cash flows used to measure the fair value of the asset under SFAS 141(R) and other applicable accounting literature. FSP FAS 142-3 is effective for financial statements issued for the fiscal years beginning after December 15, 2008.
The Company is currently evaluating the potential impact of FSP FAS 142-3 on its consolidated financial statements.

Related Party Transactions

In July 2000, we made an investment of $2.2 million in Tejas Networks India Private Limited (Tejas). The Chairman of the Board
of Directors of Sycamore also serves as the Chairman of the Board of Directors of Tejas. An executive officer of our Company also served as a board member of Tejas, until his resignation from the Tejas board on December 27, 2007. We have no
obligation to provide any additional funding to Tejas. During the fiscal years ended July 31, 2008, 2007 and 2006, we recognized revenue of $0.2 million, $0.3 million and $0.3 million, respectively, relating to transactions with Tejas. In
addition, the company also made payments to Tejas for the fiscal years ended July 31, 2008 and 2007 of $256 thousand and $42 thousand, respectively.

Eastern Research executed an OEM agreement with Tejas in March of 2006 under which Tejas provided Eastern Research with hardware, software and support for the sale of the OM 1000 product. In April of 2007
Sycamore amended the OEM agreement with Tejas to assign the agreement to Sycamore and add the OM 1500 and OM 4000 products.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Interest Rate Sensitivity

The primary objective of our current investment activities is to preserve investment principal
while maximizing income without significantly increasing risk. We maintain a portfolio of cash equivalents and short-term and long-term investments in a variety of securities which may include commercial paper, certificates of deposit, money market
funds and government debt securities. These available-for-sale investments are subject to interest rate risk and may decline in value if market interest rates increase. If market interest rates increased immediately and uniformly by 10 percent from
levels at July 31, 2008, the fair value of the portfolio would decline by approximately $1.2 million. We have the ability to hold our fixed income investments until maturity, and therefore do not expect our operating results or cash flows to be
affected to any significant degree by the effect of a sudden change in market interest rates on our investment portfolio.

Exchange Rate Sensitivity

While the majority of our operations are based in the United States, our business is global, with international revenue representing
48% of total revenue in fiscal 2008. We expect that international sales may continue to represent a significant portion of our revenue. Generally, sales outside of the United States are denominated in US dollars. In the future, to the extent that
sales outside of the United States might be denominated in local currencies, exchange rate fluctuations in foreign currencies may have an impact on our financial results, although to date such impact has not been material. We are prepared to hedge
against fluctuations in foreign currencies if the exposure is material, although we have not engaged in hedging activities to date.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of

Sycamore Networks, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of stockholders
equity and comprehensive income (loss) and of cash flows present fairly, in all material respects, the financial position of Sycamore Networks, Inc. and its subsidiaries at July 31, 2008 and 2007, and the results of their operations and their
cash flows for each of the three years in the period ended July 31, 2008 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects,
effective internal control over financial reporting as of July 31, 2008, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The
Companys management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in
Managements Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Companys internal control over financial reporting based on
our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about
whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal
control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal
control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for share-based compensation in
2006, and the manner in which it accounts for uncertain tax positions in 2008.

A companys internal control over financial reporting
is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company
are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control
over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

SYCAMORE NETWORKS, INC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Description of Business:

Sycamore Networks, Inc. (the Company) was incorporated in
Delaware on February 17, 1998. The Company develops and markets intelligent bandwidth management solutions for fixed line and mobile network operators worldwide that are designed to enable network operators to efficiently and cost-effectively
provision and manage multiservice access and optical network capacity to support a wide range of converged services such as voice, video and data as well as providing network access solutions. Sycamores global customer base includes include
domestic and international wireline and wireless network service providers, utility companies, multiple systems operators (MSOs) and government entities with private fiber networks (collectively referred to as service providers).

2.    Summary of Significant Accounting Policies:

The accompanying financial statements reflect the application of certain significant accounting policies as described below. The Company believes these accounting policies are critical because changes in such
estimates can materially affect the amount of the Companys reported net income or loss.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions
have been eliminated.

Cash Equivalents and Investments

Cash equivalents are short-term, highly liquid investments with original or remaining maturity dates of three months or less at the date of acquisition. Cash equivalents are carried at cost plus accrued interest,
which approximates fair market value. The Companys investments are classified as available-for-sale and are recorded at fair value with any unrealized gain or loss recorded as an element of stockholders equity. The fair value of
investments is determined based on quoted market prices at the reporting date for those instruments. The Company would recognize an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be
other-than-temporary. The Company considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than the Companys cost basis, the financial
condition and near-term prospects of the investee, and the Companys intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. As of July 31, 2008 and 2007, investments
consisted of (in thousands):

The Company also has certain investments in non-publicly traded companies for the promotion of
business and strategic objectives. These investments are included in other long-term assets in the Companys balance sheet and are carried at cost less appropriate reductions or impairment charges. As of July 31, 2008 and 2007, $0.2
million and $0.4 million, respectively, of these investments are included in other long-term assets.

Inventories

Inventories are stated at the lower of cost (first-in, first-out basis) or market (net realizable value).

Revenue Recognition

The Companys products
enable network operators to efficiently and cost-effectively provision and manage multiservice access and optical capacity to support a wide range of converged services such as voice, video and data. As our customer requirements have been evolving,
the software component of our product is becoming more than incidental to its functionality. Accordingly, for such arrangements where software is more than incidental to the functionality of the product, the Company recognizes revenue pursuant to
the requirements of Statement of Position (SOP) 97-2 Software Revenue Recognition, issued by the American Institute of Certified Public Accountants, as amended by SOP 98-9 Modification of SOP 97-2, Software Revenue
Recognition, With Respect to Certain Transactions. The Company will apply the provisions of SOP 97-2, as amended, to substantially all of its customer arrangements beginning in the first quarter of fiscal 2009.

In accordance with SOP 97-2, the Company begins to recognize revenue when all of the following criteria are met: the Company has evidence of an
arrangement with a customer; the Company delivers the products; agreement terms are deemed fixed or determinable and free of contingencies or uncertainties; and collection is

##### Table of Contents

probable. Evidence of an arrangement generally consists of sales contracts or agreements and customer purchase orders. Product delivery occurs when title and
risk of loss are transferred to the customer. If uncertainties exist regarding customer acceptance, the company recognizes revenue when all uncertainties are resolved. The Company assesses whether the sales price is fixed or determinable based on
payment terms and whether the sales price is subject to refund or adjustment. Collectibility is assessed based on the creditworthiness of the customer as determined by credit checks and the customers payment history to the Company.

For arrangements which include the delivery of multiple elements, revenue is allocated for all elements based on vendor-specific objective evidence,
or VSOE, of fair value. VSOE is generally the price charged when that element is sold separately or the price is established by management having the relevant authority.

In situations where VSOE exists for all elements (delivered and undelivered), the Company allocates the total revenue to be earned under the arrangement among the various elements, based on their relative fair value.
For transactions where VSOE exists only for the undelivered elements, the Company uses the residual method and defers the full fair value of the undelivered elements and recognizes the difference between the total arrangement fee and the amount
deferred as revenue. If VSOE does not exist for undelivered items that are services, then the entire arrangement fee is recognized ratably over the remaining service period. If VSOE does not exist for undelivered elements that are specified products
or features, all revenue is deferred until the earlier of the delivery of all elements or the point at which VSOE for the undelivered elements is determined.

Revenue from installation or other services is recognized as work is performed or ratably over the service period.

For arrangements in which the software component is incidental to the functionality of the product, the Company has recognized revenue in accordance with Staff Accounting Bulletin (SAB) No. 104, Revenue
Recognition, which states that revenue is realized or realizable and earned when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the price to the buyer
is fixed or determinable; and collectibility is reasonably assured. In instances where final acceptance of the product, system, or solution is specified by the customer, revenue is deferred until all acceptance criteria have been met.

For arrangements in which the software component is incidental to the functionality of the product and that involve the delivery or performance of
multiple elements, the determination as to how the arrangement consideration should be measured and allocated to the separate deliverables of the arrangement has been determined in accordance with EITF 00-21, Revenue Arrangements with Multiple
Deliverables. When an arrangement involves multiple elements, the entire fee from the arrangement is allocated to each respective element based on its relative fair value and recognized when revenue recognition criteria for each element are
met. Fair value for each element is established based on the sales price charged when the same element is sold separately. If fair value does not exist for any undelivered element, revenue is not recognized until the earlier of (i) the delivery
of the undelivered element or (ii) fair value of the undelivered element exists, unless the undelivered element is a service, in which case revenue is recognized as the service is performed once the service is the only undelivered element.

Share-Based Compensation

The Company
accounts for share-based compensation in accordance with the provisions of Statement of Financial Accounting Standards No. 123R, (SFAS 123R) Share-Based Payment, which establishes accounting for equity instruments
exchanged for employee services. Under the provisions of SFAS No. 123R, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employees
requisite service period (generally the vesting period of the equity grant).

SFAS 123R requires companies to estimate the fair value of
share-based awards on the date of grant using an option-pricing model. The value of awards that are ultimately expected to vest is recognized as expense over the requisite service periods, or in the period of grant if the requisite service period
has been provided, in the

##### Table of Contents

Companys Consolidated Statement of Operations. The Company uses the Black-Scholes option pricing model to determine the fair value of stock options
under SFAS 123R. The fair value of a restricted stock unit is equivalent to the market price of the Companys common stock on the grant date.

Property and Equipment

Property and equipment is stated at cost and depreciated over the estimated useful lives of the
assets using the straight-line method, based upon the following asset lives:



|                                          |  |                                              
|----------------------------------------- |  | ---------------------------------------------
|Computer and telecommunications equipment |  | 2 to 3 years                                 
|Computer software                         |  | 3 years                                      
|Furniture and office equipment            |  | 5 years                                      
|Leasehold improvements                    |  | Shorter of lease term or useful life of asset

The cost of significant additions and improvements is capitalized and depreciated while
expenditures for maintenance and repairs are charged to expense as incurred. Costs related to internal use software are capitalized in accordance with AICPA Statement of Position No. 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use. Upon retirement or sale of an asset, the cost and related accumulated depreciation of the assets are removed from the accounts and any resulting gain or loss is reflected in the determination of net
income or loss.

In according with SFAS 144, Accounting for the Impairment or Disposal of Long-Lived Assets, the Company
evaluates its property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Determination of recoverability is based on a comparison of the carrying value of
the asset to an estimate of the undiscounted future cash flows resulting from the use and eventual disposition of the asset. An impairment loss is recognized when the fair value of the asset, or the present value of the discounted cash flows
expected to result from the use of the asset, is less than the carrying value. Long-lived assets to be disposed of are reported at the lower of carrying value or fair value less costs to sell.

Research and Development and Software Development Costs

The Companys products are highly technical in nature and require a large and continuing research and development effort. All research and development costs are expensed as incurred. Software development costs incurred prior to the
establishment of technological feasibility are charged to expense. Technological feasibility is demonstrated by the completion of a working model. Software development costs incurred subsequent to the establishment of technological feasibility would
be capitalized until the product is available for general release to customers and amortized based on the greater of (i) the ratio that current gross revenue for a product bears to the total of current and anticipated future gross revenue for
that product or (ii) the straight-line method over the remaining estimated life of the product. To date, the period between achieving technological feasibility and the general availability of the related products has been short and software
development costs qualifying for capitalization have not been material. Accordingly, the Company has not capitalized any software development costs.

Income Taxes

Income taxes are accounted for under the liability method. Under this method, deferred tax assets and
liabilities are recorded based on temporary differences between the financial statement amounts and the tax bases of assets and liabilities measured using enacted tax rates in effect for the year in which the differences are expected to reverse. The
Company periodically evaluates the realizability of its net deferred tax assets and records a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be
realized.

The Company adopted FASB Interpretation 48, Accounting for Uncertainty in Income Taxes
(FIN48), as of August 1, 2007). FIN 48 provides the minimum recognition threshold a tax position must meet before being recognized in the Companys financial statements. Generally, recognition is limited to situations where,
based solely on the technical merits of the tax position, the Company has determined that the tax position is more likely than not to be sustained on audit. As a result of the implementation of FIN 48, no adjustment to the liability for unrecognized
income tax benefits was recognized.

Use of Estimates

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

Concentrations and Significant Customer Information

Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash equivalents, investments and accounts receivable. The Company invests its excess cash primarily in deposits with
commercial banks, high-quality corporate securities and U.S. government securities. For the year ended July 31, 2008, two customers accounted for 23% and 22% of the Companys revenue. For the year ended July 31, 2007, two customers
accounted for 53% and 16% of the Companys revenue. For the year ended July 31, 2006, three customers accounted for 43%, 26% and 19% of the Companys revenue. The Company generally does not require collateral for sales to customers,
and the Companys accounts receivable balance at any point in time typically consists of a relatively small number of customer account balances. At July 31, 2008 more than 46% of the Companys accounts receivable balance was
attributable to five customers. At July 31, 2007, more than 77% of the Companys accounts receivable balance was attributable to five customers.

Certain components and parts used in the Companys products are procured from a single source. The Company generally obtains parts from a single vendor, even where multiple sources are available, in order to
maintain quality control and enhance working relationships with suppliers. These purchases are made under purchase orders.

Allowance for Doubtful
Accounts

The Company evaluates its outstanding accounts receivable balances on an ongoing basis to determine whether an allowance for
doubtful accounts should be recorded. In fiscal 2008, the Company recorded a $4.1 million write off of a previously reserved bad debt. Activity in the Companys allowance for doubtful accounts is summarized as follows (in thousands):

Other Comprehensive Income (Loss)

The Company reports comprehensive income (loss) in accordance with Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income (SFAS 130). For all periods presented, the unrealized gain or loss on investments is recorded as a component of stockholders equity, and was the primary difference between reported net income (loss) and total comprehensive income
(loss).

Net Income (Loss) Per Share

Basic net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of common shares outstanding during the period less unvested restricted stock. Diluted net
income per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares are composed of unvested shares of restricted common
stock and the incremental common shares issuable upon the exercise of stock options and warrants outstanding. The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except per share data):

Options to purchase 22.2 million, 10.7 million and 10.9 million shares of common
stock have not been included in the computation of diluted net income (loss) per share for the years ended July 31, 2008, 2007 and 2006, because their effect would have been antidilutive.

Segment Information

The Company has determined that
it conducts its operations in one business segment. For the year ended July 31, 2008, the geographical distribution of revenue was as follows: United States52%, South Africa20%, Netherlands11%, and all other
countries17%. For the year ended July 31, 2007, the geographical distribution of revenue was as follows: United States73%, Netherlands16%, and all other countries -11%. For the year ended July 31, 2006, the geographical
distribution of revenue was as follows: United States33%, England28%, Korea18% Netherlands15%, and all other countries6%. Long-lived assets consist entirely of property and equipment and are principally located in the
United States for all periods presented.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157 Fair Value Measurements, (SFAS 157). SFAS 157 defines fair value, establishes a
framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of SFAS 157 are effective for fiscal years beginning after July 1, 2008 and as
a result, are effective for the Company in the first quarter of fiscal 2009. However, the FASB has recently approved a one year deferral for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial
statements on a nonrecurring basis. The Company has evaluated the potential impact of the SFAS 157 on its consolidated financial statements and has determined that the adoption of SFAS No. 157 is not expected to have a material effect on our
consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159,
The Fair Value Option for Financial Assets and Financial Liabilitiesincluding an amendment of FASB Statement No. 115 (SFAS 159). SFAS 159 expands

##### Table of Contents

the use of fair value accounting but does not affect existing standards which require certain assets or liabilities to be carried at fair value. The
objective of SFAS 159 is to improve financial reporting by providing companies with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge
accounting provisions. Under SFAS 159, a company may choose, at specified election dates, to measure eligible items at fair value and report unrealized gains and losses on items for which the fair value option has been elected in earnings at each
subsequent reporting date. SFAS 159 is effective for fiscal years beginning after November 15, 2007 and as a result, is effective for the Company in the first quarter of fiscal 2009. The Company has evaluated the potential impact of SFAS 159 on
its consolidated financial statements and has determined that the adoption of SFAS No. 159 is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141(R), Business Combinations (SFAS 141R). SFAS 141R replaces SFAS No. 141
and provides greater consistency in the accounting and financial reporting of business combinations. SFAS 141R requires the acquiring entity in a business combination to recognize all assets acquired and liabilities assumed in the transaction,
establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed, establishes principles and requirements for how an acquirer recognizes and measures any non-controlling interest in the
acquiree and the goodwill acquired, and requires the acquirer to disclose the nature and financial effect of the business combination. Among other changes, this statement also requires that negative goodwill be recognized in earnings as
a gain attributable to the acquisition without first reducing other acquired assets, that acquisition-related costs are to be recognized separately from the acquisition and expensed as incurred and that any deferred tax benefits resulting from a
business combination are to be recognized in income from continuing operations in the period of the combination. SFAS 141R is effective for business combinations for which the acquisition date is on or after the beginning of the first annual
reporting period beginning on or after December 15, 2008 and as a result, is effective for the Company in the first quarter of fiscal 2010. The company is currently evaluating the potential impact of SFAS 141R on its consolidated financial
statement.

In April 2008, the FASB issued Staff Position (FSP) No. FAS 142-3, Determination of the Useful Life of Intangible
Assets (FSP FAS 142-3). FSP FAS 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under SFAS No. 142, Goodwill and
Other Intangible Assets (SFAS 142). The intent of FSP FAS 142-3 is to improve the consistency between the useful life of a recognized intangible asset under SFAS 142 and the period of expected cash flows used to measure the fair value of
the asset under SFAS 141(R) and other applicable accounting literature. FSP FAS 142-3 is effective for financial statements issued for the fiscal years beginning after December 15, 2008. The Company is currently evaluating the potential impact
of FSP FAS 142-3 on its consolidated financial statements.



|3. | Acquisition of Eastern Research, Inc.
|-- | -------------------------------------

On
September 6, 2006, Sycamore Networks, Inc., through its wholly-owned subsidiary, Bach Group LLC (Bach), a Delaware limited liability company, completed its acquisition of Allen Organ Company, a Pennsylvania corporation (Allen
Organ), and its wholly owned subsidiary, Eastern Research, Inc., a New Jersey corporation (Eastern Research), through a merger of Allen Organ with and into Bach (the Merger) pursuant to an Agreement and Plan of Merger
dated as of April 12, 2006 and amended and restated as of August 3, 2006 (the Merger Agreement) by and among Sycamore, Allen Organ, MusicCo, LLC, a Pennsylvania limited liability company and wholly-owned subsidiary of Allen
Organ, LandCo Real Estate, LLC, a Pennsylvania limited liability company and wholly-owned subsidiary of Allen Organ, AOC Acquisition, Inc. and the representative of the holders of capital stock of Allen Organ.

Under the terms of the amended agreement, the Allen Organ shareholders and the minority shareholders of Eastern Research were paid an aggregate of $80
million in cash. In addition, the Company assumed all Eastern Research stock options that were outstanding immediately prior to the effective date of the transaction. All

unvested Eastern Research stock options became fully vested immediately upon the completion of the transaction. The Eastern Research stock options assumed
were converted into options to purchase approximately 951,000 shares of Sycamore common stock. The Company accounted for this acquisition using the purchase method and, accordingly, the results of Eastern Researchs operations have been
included in the consolidated financial statements since that date. The total purchase price of the acquisition was as follows (in thousands):

The Company allocated the purchase price to tangible assets, liabilities and identifiable
intangible assets acquired, as well as, in-process research and development, based on their estimated fair values. In-process research and development of $12.4 million was written-off in the first quarter of fiscal 2007 and related to a project
under development for which technological feasibility had not been established and no future alternative uses for the technology existed at the time of acquisition. The estimated fair value of the purchased in-process research and development was
determined using a discounted cash flow model, based on a discount rate which took into consideration the stage of completion and risks associated with developing the technology. The excess of the purchase price over the aggregate fair values was
recorded as goodwill, which is not deductible for tax purposes. The Company considered a number of factors to determine the purchase price allocation, including engaging a third party valuation firm to independently appraise the fair value of
certain assets acquired. Purchased intangibles are amortized on a straight-line basis over their respective estimated useful lives. The total allocation of the purchase price was as follows (in thousands):

During the first quarter of fiscal 2007, the Company decided to discontinue the development of
Eastern Researchs OX8000 product. This product was in the development stage on the date of acquisition and accordingly the fair value associated with this product was recorded as in-process research and development and expensed on the date of
the acquisition. As a result of the Companys subsequent decision to discontinue the OX8000 product, an asset impairment charge of $6.6 million was recorded in the first quarter of fiscal 2007. The charge related to certain intangible assets
associated with the OX8000 product, specifically customer relationships and other related assets. In addition, the Company recorded a charge of $1.1 million related to

OX8000 inventory in cost of product revenue in the first quarter of fiscal 2007. In the fourth quarter of fiscal 2007, the Company decided to cease further
development of Eastern Researchs BSG product. As a result, the Company recorded an asset impairment charge of $10.7 million in the fourth quarter of fiscal 2007. The charge related to certain intangible assets associated with the BSG product,
specifically technology of $7.5 million, customer relationships of $2.9 million and other related assets of $0.3 million. In addition, the Company recorded a charge of $0.3 million related to BSG inventory in cost of product revenue. In the fourth
quarter of fiscal 2008 the Company updated its estimate of future cash flows related to its intangible assets, and as a result recorded an asset impairment charge associated with DNX technology and customer relationships totaling $4.4 million. The
charge was based on the amount by which the carrying value of the intangible assets exceeded the estimated fair value. Fair value was determined based on a discounted estimate of future cash flows expected to be derived from the intangible assets.

The Company has undertaken certain restructuring activities at Eastern Research. These activities, which include reductions in staffing
and the elimination of a facility, were accounted for in accordance with Emerging Issues Task Force (EITF) Issue No. 95-3, Recognition of Liabilities in Connection with a Purchase Business Combination. The cost of these actions was
charged to the cost of the acquisition and a corresponding liability of $1.8 million was included in accrued restructuring in the accompanying balance sheet. In accordance with EITF Issue No. 95-3, the Company finalized its restructuring plans
within one year from the date of the acquisition. Upon finalization of restructuring actions or settlement of obligations for less than the expected amounts, any excess reserves are reversed with a corresponding decrease in goodwill or other
intangible assets when no goodwill exists.

Substantially all of the income
(loss) before income taxes as shown in the Consolidated Statement of Operations for the years ended July 31, 2008, 2007 and 2006 is derived in the United States.

During the years ended July 31, 2008, 2007 and 2006, the Company did not record a current tax benefit for the net operating losses due to the Companys cumulative taxable losses, the net tax losses incurred
during those periods and the inability to carryback these losses.

At July 31, 2008, the Company had federal and state net operating loss (NOL)
carryforwards of approximately $752.9 million and $246.9 million, respectively. The federal and state net operating loss carryforwards will expire at various dates through 2028. The Company also had federal and state research and development credit
carryforwards of approximately $10.8 million and $7.1 million, respectively, which begin to expire in 2019 and 2014, respectively.

In
fiscal year 1999 (just prior to the initial public offering (IPO)), the Company experienced a change in ownership as defined by Section 382 of the Internal Revenue Code. In general, an ownership change, as defined by
Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. Since the Companys formation, the Company
has raised capital through the issuance of capital stock on several occasions which, combined with shareholders subsequent disposition of those shares, has resulted in one change of control, as defined by Section 382. As a result of the
1999 ownership change, utilization of the Companys NOLs were

subject to an annual limitation under Section 382 determined by multiplying the value of the Companys stock at the time of the ownership change by
the applicable long-term tax-exempt rate resulting in an annual limitation which was fully utilized in 2000. The occurrence of subsequent ownership changes, as defined in Section 382, are not controlled by the Company, and could significantly
limit the amount of net operating loss carryforwards and research and development credits that can be utilized annually to offset future taxable income.

The Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets and has established a full valuation allowance of approximately $341.4 million for such assets,
which are comprised principally of net operating loss carryforwards, research and development credits and stock based compensation. The Company recorded a decrease to the valuation allowance of $3.7 million and $11.2 million for the years ended
July 31, 2008 and July 31, 2007, respectively, which offset the decrease in the net deferred tax assets. The decrease in the valuation allowance for the year ended July 31, 2008 was the result of the settlement of various book
reserves offset by increases in net operating losses. The decrease in the valuation allowances for the year ended July 31, 2007 was the result of utilizing previously unbenefited net operating loss carryforwards in the current period. As a
result of the adoption of SFAS No. 142, Goodwill and Other Intangible Assets and the fiscal year 2007 acquisition of Eastern Research, the Company has recorded a valuation allowance in excess of its net deferred tax assets. The excess is
computed based on the difference between the book and tax basis of indefinite lived intangible assets that is not expected to reverse during the net operating loss carryforward period. The net deferred tax liability of $0.3 and $0.2 million
respectively for the fiscal years ended July 31, 2008 and July 31, 2007 are due to the difference in accounting for the Companys goodwill, which is amortizable over 15 years for tax purposes, but not amortized for book purposes, in
accordance with SFAS No. 142. The net deferred tax liabilities cannot be offset against the Companys deferred tax assets under U.S. generally accepted accounting principles since they relate to indefinite-lived assets and are not
anticipated to reverse in the same period.

Included in the net operating loss carryforwards are stock option deductions of approximately
$125.0 million. The benefits of these stock option deductions approximate $47.8 million and will be credited to additional paid-in capital when realized or recognized. As of July 31, 2008, the Company had net operating loss carryforwards of
approximately $6.2 million related to the exercise of stock options subsequent to the adoption of SFAS 123R. This amount represents the excess benefit as defined by SFAS 123R and has not been included in the gross deferred tax asset reflected for
net operating losses. The benefit of approximately $2.0 million will be credited to additional paid-in capital and approximately $0.4 million will be credited to goodwill when the Company recognizes a cash savings.

At August 1, 2007, the Company had provided a liability of $0.9 million for unrecognized tax benefits related to various foreign income tax matters.
As of July 31, 2008, the total amount of unrecognized tax liability is $1.2 million. If recognized, the entire amount would impact the Companys effective tax rate. The Company does not expect that the amounts of unrecognized tax benefits
will change significantly within the next 12 months.

The company has adopted FASB Interpretation 48, Accounting for Uncertainty in Income
Taxes (FIN 48) as of August 1, 2007. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands):

9.    Stockholders Equity

Preferred Stock

The Companys Board of Directors
(the Board) has the authority to issue up to 5,000,000 shares of preferred stock without stockholder approval in one or more series and to fix the rights, preferences, privileges and restrictions of ownership. No shares of preferred
stock were outstanding at July 31, 2008 or July 31, 2007.

Common Stock

The Company is authorized to issue up to 2,500,000,000 shares of its common stock. The holders of the common stock are entitled to one vote for each share
held. The Board may declare dividends from legally available funds, subject to any preferential dividend rights of any outstanding preferred stock and restrictions under the Companys loan agreements, if any. Holders of the common stock are
entitled to receive all assets available for distribution on the dissolution or liquidation of the Company, subject to any preferential rights of any outstanding preferred stock.

10.    Share-Based Compensation

The Company accounts for share-based
compensation in accordance with the provisions of Statement of Financial Accounting Standards No. 123R, (SFAS 123R) Share-Based Payment, which establishes accounting for equity instruments exchanged for employee
services. Under the provisions of SFAS No. 123R, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employees service period
(generally the vesting period of the equity grant).

The following table presents share-based compensation expense included in the
Companys consolidated statements of operations for the years ended July 31, 2008, 2007 and 2006 (in thousands):

The Company estimates the fair value of stock options using the Black-Scholes valuation model. Key
input assumptions used to estimate the fair value of stock options include the exercise price of the award, the expected option term, the expected volatility of the Companys stock over the options expected term, the risk-free interest
rate over the options expected term, and the Companys expected annual dividend yield. The Company believes that the valuation technique and the approach utilized to develop the underlying assumptions are appropriate in calculating the
fair values of the Companys stock options granted in fiscal 2008, 2007 and 2006. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.

A former Company Vice President, Worldwide Sales and Support, resigned as an executive officer effective
September 6, 2006. The Company and this executive entered into a Transition Agreement and Release, which provided that, in consideration of the executives execution of such Agreement and Release and the continuation of his employment
through September 6, 2007, the executive was eligible to be covered under the Companys health plan and receive pay during such period equal to his base salary. In addition, all equity awards granted to the executive during his employment
continued to vest through September 6, 2007. The Company determined that, at the date of the Transition Agreement and Release, all service conditions had been satisfied and accordingly, the Company recorded an additional non-cash stock-based
compensation charge of $1.5 million related to this modification. Also during fiscal year 2007 the Company modified the terms of certain equity awards for approximately 75 employees to allow additional time to exercise and, as a result, the Company
recorded additional non-cash stock-based compensation expense of $0.8 million.

The fair value of each option grant was estimated on the
grant date using the Black-Scholes option-pricing model with the following assumptions:



|                               |  |           |  |           |  |

|Expected option term (1)(2)    |  | 5.9 years |  | 6.3 years |  | 6.5 years
|Expected volatility factor (3) |  | 46.0%     |  | 54.9%     |  | 60.1%

|Expected annual dividend yield |  | 0.0       |  | 0.0%      |  | 0.0%     



|(1) | Beginning in the second quarter of fiscal 2008, the Company determined the expected option term for several groups of employees based on the average expected terms for certain
groups of employees who have historically exhibited different behavior.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | The expected option term for fiscal year 2006, 2007 and the first quarter of fiscal 2008 were determined using the simplified method for estimating expected option life, which
qualify as plain-vanilla options.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | The stock volatility for each grant is measured using the weighted average of historical daily price changes of the Companys common stock over the most recent period equal to
the expected option life of the grant, adjusted for activity which is not expected to occur in the future.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | The risk-free interest rate for periods equal to the expected term of the share option is based on the U.S. Treasury yield curve in effect at the time of grant.

Stock Incentive Plans

The Company currently has four primary stock incentive plans: the 1998 Stock Incentive Plan (the 1998 Plan), the 1999 Stock Incentive Plan (the 1999 Plan), the Sirocco 1998 Stock Option Plan (the Sirocco 1998
Plan) and the Eastern Research, Inc. Stock Option Plan (the ERI Plan). A total of 139,888,642 shares of common stock have been reserved for issuance under these plans. The 1999 Plan is the only one of the four primary plans under
which new awards are currently being issued. The total number of shares that may be issued under the 1999 Plan are the remaining shares issuable under the 1998 Plan, plus 25,000,000 shares, plus an annual increase equal to the lesser of
(i) 18,000,000 shares, (ii) 5% of the outstanding shares on August 1 of each year, or (iii) a lesser number as determined by the Board. The Board of Directors of the Company (the Board) voted not to authorize an
increase in the number of shares for the 1999 Plan for fiscal year 2007 and 2008. The plans provide for the grant of incentive stock options, nonstatutory stock options, restricted stock awards and other share-based awards to officers, employees,
directors, consultants and advisors of the Company. No participant may receive any award, or combination of awards, for more than 1,500,000 shares in any calendar year. Under the 1999 Plan, options may be granted at an exercise price less than,
equal to or greater than the fair market value on the date of grant; however, options are generally granted at a price equal to fair market value of the Companys common stock on the date of grant. The Board or its delegate determines the term
of each option, the option exercise price, and the vesting terms. Stock options generally expire ten years from the date of grant and vest over three to five years.

##### Table of Contents

All employees who have been granted options by the Company under the 1998 and 1999 Plans are eligible to
elect immediate exercise of all such options. However, shares obtained by employees who elect to exercise prior to the original option vesting schedule are subject to the Companys right of repurchase, at the option exercise price, in the event
of termination. The Companys repurchase rights lapse at the same rate as the shares would have become vested under the original vesting schedule. As of July 31, 2008, there were no shares related to immediate option exercises subject to
repurchase by the Company.

The Company also has a Non-Employee Director Stock Option Plan (the Director Plan) under which a
total of 2,010,000 shares of common stock have been authorized and reserved for issuance. As of August 1 of each year, the aggregate number of common shares available for the grant of options under the Director Plan is automatically increased
by the number of common shares necessary to cause the total number of common shares available for grant to be 1,500,000. Each non-employee director, upon initial appointment as a director, is granted an option to purchase 90,000 shares which vests
over three years, and immediately following each annual meeting of stockholders, each non-employee director is automatically granted an option to purchase 30,000 shares which vests on the earlier of the next annual meeting of stockholders or one
year. The Board of Directors voted not to authorize an increase in the number of shares for the Director Plan for fiscal year 2008. The Company granted 210,000, 180,000 and 120,000 options under the Director Plan during the years ended July 31,
2008, 2007 and 2006, respectively. At July 31, 2008, 1,440,000 shares were available for grant under the Director Plan. Stock options granted under the Director Plan generally expire ten years from the date of grant and vest over one to three
years.

As of July 31, 2008, there was $13.9 million of total unrecognized compensation cost related
to nonvested share-based compensation arrangements granted under the Companys stock plans. That cost is expected to be recognized over a weighted-average period of 3.3 years.

Restricted Stock

Restricted stock may be issued to employees, officers, directors, consultants, and
other advisors. Shares acquired pursuant to a restricted stock agreement are subject to a right of repurchase by the Company which lapses as the restricted stock vests. In the event of termination of services, the Company has the right to repurchase
unvested shares at the original issuance price. The vesting period is generally three to five years. The Company issued 661 thousand shares of restricted stock during the year ended July 31, 2008, and no restricted stock during the years
ended July 31, 2007 and 2006.

The following table summarizes the status of the Companys nonvested restricted shares since
July 31, 2007:

The total fair value of shares vested during fiscal 2008, 2007 and 2006 was approximately $553
thousand, $1 thousand and $8 thousand, respectively.

Deferred Stock Compensation

In connection with the grant of certain stock options and restricted shares to employees through the year ended July 31, 2001, the Company recorded
deferred stock compensation equal to the difference between the deemed fair market value of the common stock on the date of grant and the exercise price. Deferred compensation related to options and restricted shares which vest over time is recorded
as a component of stockholders equity and is amortized over the vesting periods of the related options and restricted shares. During

the years ended July 31, 2008, 2007 and 2006, the Company recorded share-based compensation expense relating to these options and restricted shares
totaling $4.5 million, $5.3 million and $6.0 million, respectively. During the years ended July 31, 2006 and 2005, the Company reversed deferred stock compensation of $0.2 million and $0.4 million, respectively, relating to former employees
that had terminated prior to vesting in the stock options and restricted shares.

Treasury Stock

Treasury stock relates to the repurchase upon employee terminations of unvested shares of restricted stock and options exercised prior to vesting. The
shares of treasury stock held are either retired or reissued upon the exercise of options or the issuance of other share-based equity awards. During the year ended July 31, 2008 the Company held 5,000 shares of treasury stock outstanding and
also repurchased and retired 18,000 shares of treasury stock at its acquisition cost of approximately $0.

11.    Employee Benefit
Plan

The Company sponsors a defined contribution plan covering substantially all of its employees which is designed to be qualified
under Section 401(k) of the Internal Revenue Code. Eligible employees are permitted to contribute to the 401(k) plan through payroll deductions within statutory and plan limits. Company matching contributions of $0.8 million, $0.8 million and
$0.3 million were made to the plan during fiscal 2008, 2007 and 2006, respectively.

12.    Related Party Transactions

In July 2000, the Company and the Chairman of the Companys Board of Directors (the Chairman) entered into an Investor
Agreement with Tejas Networks India Private Limited, a private company incorporated in India (Tejas), pursuant to which the Company and the Chairman each invested $2.2 million in Tejas in exchange for equity shares of Tejas. The Chairman
also serves as the Chairman of the Board of Directors of Tejas. An executive officer of the Company also served as a board member of Tejas, until his resignation from the Tejas board on December 27, 2007. The Company has entered into various
agreements with Tejas under which the Company has licensed certain proprietary software development tools to Tejas, and Tejas will assist the Companys business development efforts in India and also provide maintenance and other services to the
Companys customers in India. During the years ended July 31, 2008, 2007 and 2006, the Company recognized revenue relating to transactions with Tejas of $0.2 million, $0.3 million and $0.3 million, respectively. In addition, the company
also made payments to Tejas for the fiscal years ended July 31, 2008 and 2007 of $256 thousand and $42 thousand, respectively.

Eastern Research executed an OEM agreement with Tejas in March of 2006 under which Tejas provided Eastern Research with hardware, software and support for the sale of the OM 1000 product. In April of 2007 Sycamore amended the OEM
agreement with Tejas to assign the agreement to Sycamore and add the OM 1500 and OM 4000 products.

13.    Restructuring Charges and
Related Asset Impairments

During fiscal 2007, the Company carried out various restructuring activities in connection with the Eastern
Research acquisition, which included reductions in staffing and the elimination of a facility in Michigan. The costs associated with these actions of $1.7 million were charged to the cost of the acquisition. In addition, during fiscal 2007, the
Company enacted a restructuring plan to consolidate its Moorestown, New Jersey facility and, as a result, reduced its workforce and recorded a restructuring charge of $1.5 million.

During the first quarter of fiscal 2008, the Company completed the Moorestown, New Jersey consolidation and recorded a restructuring charge of $2.0
million related to rent and other facility charges. The charge in the first quarter of 2008 also included severance costs related to several employees affected by the 2007 workforce reduction decision who had been placed on transition programs and
whose employment was terminated in the first quarter of fiscal 2008.

##### Table of Contents

During fiscal 2008 the Company recorded an additional restructuring charge related to the consolidation
of its Moorestown facility of $0.4 million. The charge was based on a revised lower estimate of future sublease income and a lease termination fee.

As of July 31, 2008, remaining future cash payments associated with these actions approximated $0.7 million and consist primarily of lease payments to be made over the next three years. A rollforward of the restructuring accrual is
summarized below (in thousands):

Litigation

IPO Allocation Case

Beginning on July 2, 2001, several purported class action complaints were filed in the United States District Court for the Southern District of New
York against the Company and several of its officers and directors (the Individual Defendants) and the underwriters for the Companys initial public offering on October 21, 1999. Some of the complaints also include the
underwriters for the Companys follow-on offering on March 14, 2000. An amended complaint, which is the operative complaint, was filed on April 19, 2002 on behalf of persons who purchased the Companys common stock between
October 21, 1999 and December 6, 2000. The amended complaint alleges claims against the Company, several of the Individual Defendants and the underwriters for violations under Sections 11 and 15 of the Securities Act of 1933, as amended
(the Securities Act), primarily based on the assertion that the Companys lead underwriters, the Company and several of the Individual Defendants made material false and misleading statements in the Companys Registration
Statements and Prospectuses filed with the Securities and Exchange Commission, or the SEC, in October 1999 and March 2000 because of the failure to disclose (a) the alleged solicitation and receipt of excessive and undisclosed commissions by
the underwriters in connection with the allocation of shares of common stock to certain investors in the Companys public offerings and (b) that certain of the underwriters allegedly had entered into agreements with investors whereby
underwriters agreed to allocate the public offering shares in exchange for which the investors agreed to make additional purchases of stock in the aftermarket at pre-determined prices. It also alleges claims against the Company, the Individual
Defendants and the underwriters under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the Exchange Act), primarily based on the assertion that the Companys lead underwriters, the Company and the
Individual Defendants defrauded investors by participating in a fraudulent scheme and by making materially false and misleading statements and omissions of material fact during the period in question. The amended complaint seeks damages in an
unspecified amount.

The action against the Company is being coordinated with approximately three hundred other nearly identical actions
filed against other companies. Due to the large number of nearly identical actions, the court has ordered the parties to select up to twenty test cases. To date, along with sixteen other cases, the Companys case has been selected
as one such test case. As a result, among other things, the Company will be subject to broader discovery obligations and expenses in the litigation than non-test case issuer defendants.

On October 9, 2002, the court dismissed the Individual Defendants from the case without prejudice. This dismissal disposed of the Section 15
and Section 20(a) claims without prejudice, because these claims were asserted only against the Individual Defendants. On October 13, 2004, the court denied the certification of a class

##### Table of Contents

in the action against the Company with respect to the Section 11 claims alleging that the defendants made material false and misleading statements in
the Companys Registration Statement and Prospectuses. The certification was denied because no class representative purchased shares between the date of the IPO and January 19, 2000 (the date unregistered shares entered the market), and
thereafter suffered a loss on the sale of those shares. The court certified a class in the action against the Company with respect to the Section 10(b) claims alleging that the Company and the Individual Defendants defrauded investors by
participating in a fraudulent scheme and by making materially false and misleading statements and omissions of material fact during the period in question. On December 5, 2006, the Second Circuit vacated the district courts class
certification decision. On April 6, 2007, the Second Circuit panel denied a petition for rehearing filed by the plaintiffs, but noted that the plaintiffs could ask the district court to certify a more narrow class than the one that was
rejected.

Prior to the Second Circuits December 5, 2006 ruling, a majority of the issuers, including the Company, and their
insurers had submitted a settlement agreement to the district court for approval. In light of the Second Circuit opinion, the parties agreed that the settlement could not be approved. On June 25, 2007, the district court approved a stipulation
filed by the plaintiffs and the issuers terminating the proposed settlement. On August 14, 2007, the plaintiffs filed a Second Amended Class Action complaint against the Company. The amended complaint contains a number of changes, including
changes to the definition of the purported class of investors, and the elimination of the Individual Defendants as defendants. The Company and the underwriters filed separate motions to dismiss the amended complaint on November 14, 2007. On
March 26, 2008, the Court denied the motion to dismiss the Section 10(b) claims but dismissed certain Section 11 claims against the Company. On June 5, 2008, the Court dismissed the remaining Section 11 claims against the
Company in response to a motion for partial reconsideration. On September 27, 2007, the plaintiffs filed a motion for class certification in the Companys case. On December 21, 2007, the Company and the underwriters filed papers
opposing class certification. On March 28, 2008, Plaintiffs filed their reply brief in support of their motion for class certification. We are awaiting the District Courts decision on the motion for class certification.

The Company cannot predict whether the parties will be able to negotiate a revised settlement that complies with the standards set out in the Second
Circuits decision. Due to the inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of the matter. If the parties are not able to renegotiate a settlement and the Company is found liable, the Company
is unable to estimate or predict the potential damages that might be awarded, whether such damages would be greater than the Companys insurance coverage, and whether such damages would have a material impact on our results of operations or
financial condition in any future period.

Derivative Lawsuits

On May 31, 2006, a purported shareholder derivative action, captioned Weisler v. Barrows (Weisler), was filed in the United States
District Court for the District of Delaware (the Delaware Court), on the Companys behalf, against it as nominal defendant, the Companys Board of Directors and certain of its current and former officers (as amended on
October 4, 2006). The plaintiff derivatively claims, among other things, violations of Section 14(a) of the Securities Exchange Act of 1934, Section 304 of the Sarbanes-Oxley Act of 2002, and breaches of fiduciary duty by the
defendants in connection with the Companys historical stock option granting practices. The plaintiff seeks unspecified damages, profits, the return of compensation paid by the Company, an injunction and costs and attorneys fees.
Substantially similar actions, captioned Vanpraet v. Deshpande (Vanpraet) and Patel v. Deshpande (Patel), were filed in the United States District Court for the District of Massachusetts on June 28, 2006 and
July 13, 2006, respectively (the Massachusetts Court), and Ariel v. Barrows (Ariel) was filed on July 21, 2006 in the United States District Court for the Eastern District of New York (the New York
Court). None of the plaintiffs made presuit demand on the Companys Board of Directors prior to filing suit. By Memorandum and Order dated November 6, 2006, the Delaware Court transferred Weisler to the District of Massachusetts. By
stipulation of the parties, on November 21, 2006, the New York Court transferred Ariel to the District of Massachusetts. By margin order dated May 24, 2007, the Massachusetts Court

consolidated Weisler, Vanpraet, Patel and Ariel (the Federal Action). Subsequent to that consolidation, plaintiffs in the Federal Action served a
demand letter on the Company, which has since been refused. Proceedings in the Federal Action are currently stayed. The Federal Action does not seek affirmative relief from the Company.

On September 19, 2006, an additional purported shareholder derivative action, captioned McMahon v. Smith, was filed in the Middlesex Superior Court
for the Commonwealth of Massachusetts, on the Companys behalf, against it as nominal defendant, the Companys Board of Directors and certain of its current and former officers. The plaintiff derivatively claims, among other things,
breaches of fiduciary duty by the defendants in connection with the Companys historical stock option granting practices, and also that certain defendants misappropriated confidential Company information for personal profit by selling
Company stock while in possession of material, non-public information. The plaintiff sought unspecified damages, profits, an injunction and costs and attorneys fees. The plaintiff did not make presuit demand on the Companys Board of
Directors prior to filing suit. An amended complaint was filed on July 16, 2007 which also named additional officers of the Company as defendants. On August 15, 2007, the defendants filed a motion to dismiss and on November 19, 2007,
the court heard oral arguments on that motion. By a Memorandum and Order dated March 6, 2008, the Court granted the defendants motion and dismissed the case with prejudice and without leave to file a further amended complaint. The
plaintiff did not appeal that decision. The purported derivative action did not seek affirmative relief from the Company.

In October 2007,
a purported Sycamore Networks, Inc. shareholder filed a complaint for violation of Section 16 of the Securities Exchange Act of 1934, which prohibits short-swing trading against the Companys Initial Public Offering underwriters. The
complaint, Vanessa Simmonds v. Morgan Stanley, et al., in District Court for the Western District of Washington seeks recovery of short-swing profits. On April 28, 2008, the district court established a briefing schedule for motions to dismiss
and ruled that all discovery be stayed pending resolution of the motions to dismiss. On July 25, 2008, the Company and the Initial Public Offering underwriters filed motions to dismiss the complaint. The Company is named as a nominal
defendant. No recovery is sought from the Company in this matter.

Other Matters

On or about July 9, 2008, the Commissioners of the Securities and Exchange Commission (the SEC) authorized the final settlement between
the Company and the SEC in connection with the previously disclosed investigation into the Companys historical stock option granting practices and related accounting. Without admitting or denying the allegations in the SECs complaint,
the Company agreed to settle the charges by consenting to a permanent injunction against any future violations of the federal securities laws. No monetary penalties were assessed against the Company in conjunction with the settlement. This
settlement concludes the SECs investigation into the Companys historical stock option granting practices and related accounting.

On June 29, 2006, a former employee of the Company filed a complaint in Massachusetts Superior Court alleging, among other things, claims relating to wrongful termination of an employment agreement, fraud in the inducement, retaliation
and claims relating to certain of the Companys stock option grant practices in 1999-2001. The complaint demanded lost wages, unspecified monetary damages and reinstatement of medical benefits, among other things. The case was moved to the
Business Litigation Session of the Suffolk County Superior Court and, following an oral hearing on a motion to dismiss, the case was ordered dismissed on January 24, 2007. The plaintiff has filed a Notice of Appeal of the order and judgment.

Guarantees

FASB Interpretation
No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others (FIN 45), requires that upon issuance of a guarantee,

the guarantor must disclose and recognize a liability for the fair value of the obligation assumed under that guarantee. As of July 31, 2008, the
Companys guarantees requiring disclosure consist of its accrued warranty obligations, indemnifications for intellectual property infringement claims and indemnifications for officers and directors.

In the normal course of business, the Company may also agree to indemnify other parties, including customers, lessors and parties to other transactions
with the Company, with respect to certain matters. The Company has agreed to hold these other parties harmless against losses arising from a breach of representations or covenants, or other claims made against certain parties. These agreements may
limit the time within which an indemnification claim can be made and the amount of the claim. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification
claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made by the Company under these agreements have not had a material impact on the Companys operating results or financial position.
Accordingly, the Company has not recorded a liability for these agreements at July 31, 2008 or July 31, 2007 as the Company believes the fair value is not material.

The Company has agreed to indemnify its officers and directors for certain events or occurrences arising as a result of the officer or director serving
in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is not limited; however, the Company has directors and officers insurance coverage that reduces its
exposure and may enable the Company to recover a portion of any future amounts paid. The Company has incurred expenses under these agreements of $2.1 million and $2.4 million for fiscal years 2008 and 2007, respectively, on behalf of eligible
persons for legal fees incurred by them in connection with the stock option investigations, the resulting restatement of previously issued financial statements and the subsequent inquiry by the SEC and DOJ of information and documentation related
thereto. Due to the Companys inability to estimate its liabilities in connection with these agreements, the Company has not recorded a liability for these agreements at July 31, 2008 or July 31, 2007. The Company maintains insurance
policies whereby certain payments may be recoverable subject to the terms and conditions provided in such policies. During fiscal 2008, the Company received $2.3 million in recoveries under such policies.

Warranty liability

The Company records a warranty
liability for parts and labor on its products at the time revenue is recognized. Warranty periods are generally three years from installation date. The estimate of the warranty liability is based primarily on the Companys historical experience
in product failure rates and the expected material and labor costs to provide warranty services.

activity related to the product warranty liability (in thousands):

|ITEM 9. | CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
|------- | ------------------------------------------------------------------------------------

None.



|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of
Disclosure Controls and Procedures.Our management (with the participation of our Chief Executive Officer and Chief Financial Officer) evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e)
and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)), as of July 31, 2008. Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the
reports it files or submits under the Exchange Act is recorded, processed, summarized and reported on a timely basis and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial
Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures are effective and designed to
ensure that the information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the requisite time periods.

Limitations on Effectiveness of Controls. Our management has concluded that our disclosure controls and procedures and internal controls provide
reasonable assurance that the objectives of our control system are met. However, our management (including our Chief Executive Officer and Chief Financial Officer) does not expect that the disclosure controls and procedures or internal controls will
prevent all error and/or fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, 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. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control
issues, errors and instances of fraud, if any, within the company have been or will be detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple errors
or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system is also based in part upon certain assumptions
about the likelihood of future events, and there can be no assurances that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system,
misstatements due to error or fraud may occur and may not be detected.

Managements Report on Internal Control over Financial
Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the
Exchange Act as a process designed by, or under the supervision of, the Companys Chief Executive Officer and Chief Financial Officer and effected by the Companys Board of Directors, management and other personnel, to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:



| |  |  | Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Companys assets that could have a
material effect on the financial statements.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of July 31, 2008. In
making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal ControlIntegrated Framework.

Based on our assessment, management concluded that, as of July 31, 2008, our internal control over financial reporting was effective based on those
criteria.

The Companys independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued an audit report on
managements assessment of the companys internal control over financial reporting, which is included herein.

Changes in
Internal Control over Financial Reporting. There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during our fourth fiscal quarter that has materially affected,
or is reasonably likely to materially affect, our internal control over financial reporting.
