Industry Background

Industry Trends

During the past several years, individual consumers and businesses have come to increasingly rely on private and public networks for services
that support a broad range of communications applications. In the mid-1990s new communications technologies contributed to the growth of data-centric wide area networks optimized for emerging consumer and enterprise applications such as virtual
private networks, web browsing, e-mail and file transfer. Beginning in the late 1990s, fixed line and mobile networks around the world began to evolve in order to accommodate a steady increase in demand for more bandwidth-intensive applications and
services such as high-speed Internet access, storage area networks, on-demand video, online gaming, high-definition TV and mobile Internet. More recently, demand for broadband communications has continued to increase due to advances in end-user
devices such as smart phones and netbooks, the growth of online information and multimedia entertainment and the widespread popularity of social networking applications.

The evolution of broadband communications has affected all segments of the infrastructure network, from mobile base stations in remote rural areas to the high-capacity, fiber optic transmission links
connecting major metropolitan areas. In order to build flexible, resilient and cost-effective networks to support high-bandwidth, delay-sensitive voice and data communications, we believe that service providers require network equipment that
supports diverse service interfaces, simplified management of end-to-end network connections, and the efficient utilization of network capacity. Sycamore refers to these capabilities as Intelligent Bandwidth Management.

##### Table of Contents

Despite the opportunities that emerged during the evolution of service provider networks,
the market for communications equipment required to support high-speed networking has experienced significant challenges, including the sharp decline in demand for networking equipment in 2001 and the more recent slowdown in service provider
equipment purchases due to a deteriorating macroeconomic environment. These market forces have been key drivers behind industry consolidation and a global trend among the larger service providers to reduce the number of communications equipment
suppliers in their networks. As a result, the market for Intelligent Bandwidth Management products has been subject to concentration of purchasing power, extreme pricing pressure, and competitive leverage for incumbent equipment suppliers. These
market forces create a very challenging business environment for Sycamore. We believe the service provider markets that Sycamore serves have been and will continue to be impacted by the recent global downturn, resulting in reduced or delayed capital
spending on networking projects.

Intelligent Bandwidth Management Market

Multiservice access, regional backhaul, and core optical networks remain 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. Our 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 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 continue to own and operate traditional infrastructure networks that were originally designed 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.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Competition

The number of opportunities for Sycamore products 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 and the trend among the larger service providers to reduce the number of communications equipment suppliers in their networks, we
expect that competition will continue to be intense.

Sycamores competition includes large incumbent suppliers of
network infrastructure equipment and optical networking equipment, such as Alcatel-Lucent, Ciena Corporation, Cisco Systems, Inc., Sony Ericsson Mobile Communications AG, Fujitsu Limited, Huawei Technologies Corporation, Nortel Networks Corporation,
Nokia Siemens Networks and Tellabs, Inc. The multiservice access market is equally competitive, with a highly fragmented group of suppliers which includes Tellabs, Alcatel-Lucent, Adtran, Inc. and Kentrox, Inc. 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 broader product lines which allow them the flexibility to price their products more aggressively and absorb the significant cost structure associated with 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, our products must:



| |  |  | provide a cost-competitive solution that enables service providers to efficiently deploy and manage bandwidth services;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | lower a service providers cost of building and operating their communications infrastructure;
| | - |  | ----------------------------------------------------------------------------------------------



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



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



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



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

Sycamores Strategy

We remain cautious in the current economic
environment. As a result, we continue to prudently manage expenses and pace future investments to more closely match the slower than previously expected rate of adoption of new technologies. We believe that market conditions are unlikely to
meaningfully improve in the near term, and thus we will continue to monitor and pace our current and planned research and development initiatives to ensure our resources are effectively aligned to support the needs of our customers as well as to
explore new market opportunities.

As we navigate through todays market challenges, we will continue to focus on
improving and advancing our business. In addition, we continue to consider strategic options that may serve to maximize shareholder value. These options include, but are not limited to (i) acquisitions of, or mergers or other combinations with,
companies with complementary technologies or in other market segments, (ii) alliances with other entities and (iii) recapitalization alternatives, including stock buybacks, cash distributions or cash dividends.

Key elements of our strategy include the following:



| |  |  | Focus our research and development investments.We believe that market conditions are unlikely to meaningfully improve in the near term. As a
result, we will pace our current and planned research and development initiatives to ensure our resources are effectively aligned to support the needs of our current and prospective customers as well as explore selective new opportunities in current
and other markets.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Manage costs.We believe that our strong cash position coupled with no debt differentiates us from many of our competitors. While we continue to
invest in both tactical and strategic areas of the business, we also continue to focus on cost management and exercise financial discipline.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expand our customer base.We continue to pursue new customers both domestically and internationally, while continuing to expand our
relationships with existing customers. We intend to pursue new customers via direct sales efforts as well as through channel partners.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Expand strategic relationships including resellers. Our sales and marketing efforts involve building and broadening strategic relationships,
particularly with resellers, to expand our access to a broader set of customers around the world. We believe that such relationships can address portions of the market, such as the government market or certain international markets, which we cannot
reach with our own sales force without a significant investment of time and resources.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Outsource manufacturing.We outsource the manufacturing of our products and purchase key components from third parties. Outsourcing enables us
to better control product costs and focus on our core competencies, such as product development, sales and customer service.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

As noted above, we believe the service provider markets that Sycamore serves have been and
will continue to be impacted by the recent global economic downturn, resulting in reduced or delayed capital spending on networking projects. Our lower revenue in fiscal 2009 reflects the impact of this reduced capital spending. The constraints in
capital spending have compounded the Companys pre-existing challenges of customer concentration and unpredictability, particularly for our core switching products, and led us to initiate certain cost reduction actions during the fourth quarter
of fiscal 2009. These actions were in addition to actions previously taken during the first and second quarters of fiscal 2009. The fourth quarter actions were taken in order to re-align our cost structure, pace our development in line with customer
requirements with a more measured view toward future offerings, and to better position the Company for success in the longer-term. The combination of current business, economic and market conditions, together with our current estimate of future
demand and the resultant cost reduction actions initiated during the fourth quarter, combined to give rise to an impairment in the carrying value of the Companys goodwill, intangible assets and certain fixed assets during the fourth quarter of
fiscal 2009.

Customers

Our current and prospective customers include domestic and international wireline and wireless network service providers, utility companies, large enterprises, multiple systems operators and government
entities. We expect that our revenue will continue to be highly concentrated in a relatively small number of customers.

During the year ended July 31, 2009, two customers, Verizon Communications, Inc. and Sprint Nextel Corporation, accounted for 19% and 12% of our revenue, respectively. During the year ended July 31, 2008, two customers, Sprint
Nextel Corporation and Nokia Siemens Networks, accounted for 23% and 22% of our revenue, respectively. During the year ended July 31, 2007, two customers, Sprint Nextel Corporation and Vodafone Group, PLC, accounted for 53% and 16% of our
revenue, respectively. International revenue was 35% of total revenue during the year ended July 31, 2009, compared to 48% during the year ended July 31, 2008, and 27% during the year ended July 31, 2007. 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 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, government entities 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

We sell our products worldwide through a direct sales
force that includes a local presence in select international markets. In certain markets we utilize strategic distribution partners, resellers or independent sales consultants. We continue to pursue relationships with such partners to expand our
sales and marketing opportunities.

Our sales and pre-sales engineering teams work collaboratively with both current and
prospective customers to identify applications and configure solutions that help optimize their networks. The sales cycle for our products tends to be long due to extensive pre-sales testing and evaluation required for the types of network solutions
that we sell, in particular our optical switching solutions.

We also provide comprehensive post-sales customer support
offerings including network planning and deployment, logistics, product training, online technical assistance and maintenance contracts. Our customer support organization also leverages a network of highly qualified service partners to extend our
reach and capabilities.

##### Table of Contents

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

Research and Development

Our research and development efforts focus on enhancements to existing products with a more measured approach to future offerings and investments in new technologies and solutions. We will ensure our resources are effectively aligned to
support the needs of our current and prospective customers as well as to explore selective new opportunities in current and other markets.

Our research and development expenses were $50.1 million, $47.4 million and $45.9 million for the years ended July 31, 2009, 2008 and 2007, respectively. All of our costs related to research and
development, including share-based compensation of $2.0 million, $1.8 million and $1.7 million, for the years ended July 31, 2009, 2008 and 2007, respectively, have been expensed as incurred.

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 has 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, 2009, we had received 38 United States patents and had pending 7 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, 2009, 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 variety of suppliers 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.

---

##### Table of Contents

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 ensure 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 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, 2009, we employed 405 persons. We estimate that our headcount upon completion of the cost reductions actions initiated in
the fourth quarter of fiscal 2009 will approximate 300. 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;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | 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 which may cause downward pressure on the pricing of our
products resulting in reduced gross margins and constrained revenue growth;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | many of our competitors have broader product lines than we do, which allows 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.

Our revenue currently depends on the continued commercial success of our optical switching and multiservice access products.

Our current revenue depends on the continued 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 currently focus primarily on these products, in addition to investments in the development of new technologies and solutions. In order to remain
competitive, we believe that continued investment in research and development is necessary in order to provide compelling solutions to our current and prospective customers. We cannot assure you that we will be successful in:



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



| |  |  | completing the development, introduction, production or successful sales and marketing of new products or technologies; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------



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

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 and solutions, 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 completed merger transactions which have had 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.

##### Table of Contents

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, 2009, we had $347.7 million in cash and cash equivalents plus
$579.1 million in short-term and long-term investments in marketable 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.

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.

The markets for our products are characterized by rapidly changing technology, frequent introductions of new products and evolving customer
requirements. Customers continuously demand new features for existing products as well as new technologies and solutions. We may not develop or may fail to develop new features or products sought after by customers. We may also allocate development
resources toward products or technologies for which market demand is ultimately lower than anticipated. Market demand and/or competitive pressures may also cause us to alter our investment in existing products, discontinue certain products, or
redirect our investments to alternative market opportunities. Such actions could have an adverse impact on our future revenue and results of operations. 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 future 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 operating profitability.

Restructuring activities could disrupt our business and affect our results of operations.

We have previously taken and are in the process of implementing steps, including workforce reductions, facilities consolidation, office
closures, and internal reorganizations to reduce the size and cost of our operations and to better align our resources with market opportunities. We may need to take similar steps in the future. These restructuring efforts may be disruptive to our
business and would likely result in charges to earnings. If we are unable to implement our restructuring plans effectively, we may not achieve the level of cost savings and efficiency benefits expected, causing harm to our business.

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, Huawei, Nortel, Ericsson,
and Tellabs have historically dominated this market and may be in a better position to take advantage of the trend among larger service providers to reduce the number of communications suppliers in their network. 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 and often deploy aggressive pricing tactics in order to compete with our products. Our competitors may develop new technologies that compete with our products or even render our
products less desirable or even obsolete. Moreover, many of 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.



13



---

##### Table of Contents

As a result of the intensified competition, we expect to encounter competitive 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.

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. 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 network 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 utilize channel relationships with distribution partners including resellers, distributors and systems integrators for the sale of our products to service providers including government entities. We have
entered into agreements with several distribution partners, some of which 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.

##### Table of Contents

Through our resellers, we generate a portion of our revenue from government entities and the loss or
decline of existing or future government entity funding could adversely affect our revenue and cash flows.

These
government entities 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 entities to terminate projects, divert funds or delay
implementation or expansion. A significant reduction or delay in orders by one or more of these entities could significantly reduce our revenue and cash flows. As with most government contracts, these entities may terminate the contracts
at any time without cause. Additionally, government contracts are generally subject to audits and investigations by government entities. 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 negatively impact our results of operations.

Large communications providers, key resellers
and government entities, who make up a large part of our business, have substantial purchasing power and potential leverage in negotiating contractual arrangements with us. As we seek to increase sales with such larger customers, we may be required
to agree to unfavorable contractual arrangements, which may include (i) higher discounts, (ii) development of additional features, (iii) penalty clauses or (iv) other terms and conditions which may affect the timing of revenue
recognition, our financial condition and/or our reported results of operations.

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. 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. Further, 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 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 anticipated benefits of any acquisition or strategic investment will also involve certain other risks, including:



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



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

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.

Whether or not we pursue acquisitions or strategic investments, 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 other markets to add complementary products and services, expand the markets we serve and diversify our customer base. We cannot predict whether, or when, we may be able
to consummate such acquisitions or strategic investments or that such acquisitions or strategic investments would provide a positive return on investment. Accordingly, whether or not we pursue any such acquisitions or strategic investments, the
value of our shares may decrease.

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 greater fluctuations in our operating results. Our planned expense levels depend in part on our expectations of future revenue. 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;
| | - |  | ---------------------------------------------------------------------------

| |  |  | 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 custom designed 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 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 the availability of 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.



17



---

##### Table of Contents

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 several years, 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 35% of total revenue for fiscal 2009 and
48% of total revenue for fiscal 2008. We have a substantial international customer base and we are subject to foreign exchange translation risk to the extent that our revenue is



18

##### Table of Contents

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, which conducts a significant amount of our research and development activities. 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 re-export 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.

##### Table of Contents

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, 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 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



20

##### Table of Contents

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. While we believe that we have adequately provided for our tax liabilities, 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.

Utilization of our net operating loss and tax credit
carryovers could be subject to significant limitations pursuant to Section 382 of the Internal Revenue Code.

The
Company has significant federal and state net operating loss and tax credit carryovers. Our ability to utilize our net operating losses may be subject to limitations pursuant to the ownership change rules of Section 382 of the Internal Revenue
Code, as amended. The occurrence of ownership changes, as defined in Section 382, is not controlled by the Company, and could significantly limit the amount of net operating loss carryovers and research and development credits that can be
utilized annually to offset future taxable income.

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 may expose us to additional 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.

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 new or
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.

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, 2009, 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

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.

We also own a parcel of undeveloped land, containing approximately 102 acres, in Tyngsborough, Massachusetts.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

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



23



---

##### Table of Contents

ordered the parties to select up to twenty test 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.

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. On October 10, 2008, the Court granted Plaintiffs request to
withdraw, without prejudice, their motion for class certification.

On April 3, 2009, the Plaintiffs submitted to the
Court a motion for preliminary approval of a settlement of the approximately 300 coordinated cases, which includes the Company, the underwriter defendants in its class action lawsuit, and the plaintiff class in its class action lawsuit. The insurers
for the issuer defendants in the coordinated cases will make the settlement payment on behalf of the issuers, including the Company. The settlement is subject to termination by the parties under certain circumstances, and is subject to Court
approval. The final settlement hearing was held on September 10, 2009. To date, the Court has not issued a ruling on the settlement.

Due to the inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of the matter. If the settlement is not approved or the parties terminate the settlement, the
litigation continues, 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 claimed, 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 sought 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. The Federal Action did not seek affirmative relief from the Company. On May 1, 2009, the Massachusetts Court approved the
plaintiffs voluntary dismissal of the Federal Action without prejudice, except as to demand futility, which was dismissed with prejudice.

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 (District Court) 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. The District Court found the motions appropriate for oral
argument which was held on January 6, 2009. On March 16, 2009, the District Court issued an order dismissing the case. On March 31, 2009, the plaintiff appealed, and the Appeals Court established a briefing schedule. The Company is
named as a nominal defendant. No recovery is sought from the Company in this matter.

Other Matters

On June 29, 2006, a former employee of the Company filed a complaint against the Company and the Companys Chief Executive Officer
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. Appellate briefing was completed on May 1, 2009. Oral argument has been
scheduled for October 14, 2009.

From time to time the Company is a party to litigation and other disputes which we
consider routine and incidental to our business. Management does not expect the results of any of these actions to have a material adverse effect on our business, results of operations or financial condition.

|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, large enterprises, multiple systems operators and government entities
(collectively referred to as service providers). Our portfolio of optical switches, multiservice cross-connects and multiservice access platforms serve applications that extend across the network infrastructure, from multiservice access
and regional backhaul to the optical core. We believe our products enable network operators to efficiently and cost-effectively provision and manage network capacity to support a wide range of converged services such as voice, video and data.

Total revenue for fiscal 2009 was $67.4 million, a decrease of 42% compared to fiscal 2008. Total revenue for fiscal 2008 was
$115.5 million, a decrease of 26% compared to fiscal 2007. Our net loss for fiscal 2009 was $53.6 million compared to a net loss for fiscal 2008 of $0.1 million.

We operate in a challenging business environment. We believe the service provider markets that the Company serves have been and will continue to be impacted by the recent global economic downturn,
resulting in reduced or delayed capital spending. Our lower revenue and net loss in fiscal 2009 reflects the impact of this reduced capital spending. The constraints in capital spending have compounded the Companys pre-existing challenges of
customer concentration and unpredictability, particularly for our core switching products, and led us to initiate certain cost reduction actions during the fourth quarter of fiscal 2009. These actions were in addition to the actions previously taken
during our first and second quarters of fiscal 2009. We anticipate that the annualized cost savings across all functional areas associated with these actions will approximate $20.0 million. The fourth quarter actions were taken in order to re-align
our cost structure, pace our development in line with customer requirements with a more measured view toward future offerings, and to better position the Company for success in the longer-term. The combination of current business, economic and
market conditions, together with our current estimate of future demand and the resultant cost reduction actions initiated during our fourth quarter, combined to give rise to an impairment in the carrying value of the Companys goodwill and
intangible assets during the fourth quarter of fiscal 2009, requiring a non-cash impairment charge of $23.1 million. The charge represents the full carrying value of such assets on the Companys balance sheet. An additional non-cash impairment
charge of $1.1 million was also applicable to certain fixed assets. Net loss for fiscal 2009 includes total asset impairment charges of $24.2 million. Impairment charges included in net loss for fiscal 2008 were $4.4 million.

We remain focused on improvements in our business. We 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 other markets to add complementary products and services, expanding the markets we serve and diversifying our customer base.

Our total cash, cash equivalents and investments were $926.8 million at July 31, 2009. Included in this amount were cash and cash
equivalents of $347.7 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 at least 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, 2009, Sycamore and its subsidiaries employed 405 persons, which was a net decrease of 87 persons from the 492 persons employed on July 31, 2008. We estimate that our headcount upon completion of the cost reductions actions
initiated in the fourth quarter of fiscal 2009 will approximate 300.

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, 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 service providers 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 evolved, the software component of our product has become 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 applied 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 recognizes revenue when all of the following criteria
are met: the Company has persuasive evidence of an arrangement with a customer; the Company delivers the products; the fee is fixed or determinable; 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.

Collectability 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 was incidental to the functionality of the product, the Company 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 collectability 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 was incidental to the functionality of the product and that involved 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 was determined in accordance with EITF 00-21, Revenue Arrangements with Multiple Deliverables. When an arrangement involved multiple elements, the entire fee from the arrangement was allocated to each respective
element based on its relative fair value and recognized when revenue recognition criteria for each element was met. Fair value for each element was established based on the sales price charged when the same element was sold separately. If fair value
did not exist for any undelivered element, revenue was not recognized until the earlier of (i) the delivery of the undelivered element or (ii) fair value of the undelivered element existed, unless the undelivered element was a service, in
which case revenue was recognized as the service was performed once the service was the only undelivered element.

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. The primary factors that are considered in assessing the nature of the impairment include; (i) the credit quality of the underlying security,
(ii) the extent to which and time period during which the fair value of the investment has been below cost, (iii) the expected holding or recovery period for the investment, (iv) the Companys intent to hold each investment until
recovery and the likelihood that the Company will not be required to sell the security prior to recovery, and (v) the existence of evidence of default by the issuer.

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 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.

Litigation and Other 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, Intangible Assets, and Other Long-lived Assets

As a result of our acquisition of Eastern Research, Inc., the Company recorded goodwill in the amount of $20.3 million. This amount represented the remaining excess of the total purchase price of the
Eastern Research acquisition over the fair value of the net assets acquired. We also identified and recorded intangible assets as a result of the acquisition.

Goodwill is subject to annual impairment testing as well as testing upon the occurrence of any event that indicates a potential impairment in accordance with SFAS No. 142, Goodwill and Other
Intangible Assets. We also review other long-lived assets, including purchased intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable in
accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. The carrying value and ultimate realization of these assets is dependent upon estimates of future results and cash flows that our
single reporting unit expects to generate from their use. If our expectations of future results and cash flows are significantly diminished, intangible assets and goodwill may be impaired and the resulting charge to operations may be material. When
we determine that the carrying value of intangibles or other long-lived assets may not be recoverable based upon the existence of one or more indicators of impairment, we use the projected undiscounted cash flow method to determine whether an
impairment exists, and then measure the impairment using discounted cash flows. To measure impairment for goodwill, we compare the fair value of our single reporting unit by measuring discounted cash flows to the book value of the reporting unit.
Goodwill would be impaired if the resulting implied fair value of goodwill was less than the recorded book value of the goodwill.

The estimation of useful lives and expected cash flows require us to make significant
judgments regarding future periods that are subject to some factors outside of our control. Changes in these estimates can result in significant revisions to the carrying value of these assets and may result in material charges to the results of
operations.

The Company has elected to perform its annual goodwill impairment testing as required under SFAS 142 on the
last business day of our fiscal month June, or more often if events or circumstances indicate that there may be impairment. Reporting units are defined as operating segments or one level below an operating segment, referred to as a component. The
Company has determined that our single reporting unit is a component of our one operating segment. The Company allocates goodwill to the reporting unit at the time of acquisition. The estimated fair value of our reporting unit is based on a
discounted cash flow model derived from internal earnings and external market forecasts. Assumptions in estimating future cash flows are subject to a high degree of judgment and complexity.

During the fourth quarter of fiscal 2009, and in connection with the preparation of its revised plan for fiscal 2010 and its outlook beyond,
the Company updated its estimates of future demand for its core and access products. The revised outlook resulted in a projection of lower discounted cash flows. The combination of current business, economic and market conditions, together with our
current estimate of future demand and the resultant cost reduction actions initiated during our fourth quarter, combined to give rise to an impairment in the carrying value of the Companys goodwill and intangible assets during the fourth
quarter of fiscal 2009. The Company recorded an impairment charge of $20.3 million for the entire carrying value of goodwill and an impairment charge of $2.8 million for the remaining carrying value of identified intangible assets. An additional
impairment charge of $1.1 million was also recorded related to certain fixed assets.

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. There was no impairment of goodwill in fiscal 2008 or 2007.

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 2009 compared to fiscal 2008. Product revenue
consists primarily of sales of our Intelligent Bandwidth Management solutions. Product revenue decreased in fiscal 2009 compared to fiscal 2008 primarily due to deteriorating market and economic conditions, which created a slowdown in capital
spending by service providers in general and, more specifically, a significant reduction in the level of orders from two customers. Service revenue consists primarily of fees for services relating to the maintenance of our products, installation
services and training. Service revenue decreased in fiscal 2009 compared to fiscal 2008 primarily due to a decrease in the level of installation and training revenues offset by a slight increase in maintenance revenue.

For fiscal 2009, two customers accounted for 19% and 12% of revenue, or a combined 31% of our total revenue. Two customers accounted for 23%
and 22% of revenue in fiscal 2008, or a combined 45% of our total revenue. International revenue represented 35% of revenue in fiscal 2009, compared to 48% of revenue in fiscal 2008. 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.

Product gross profit

Cost of product revenue consists primarily of amounts paid to third-party contract manufacturers for purchased materials and services,
internal manufacturing costs as well as provisions for warranty and rework costs and adjustments which may be required to reduce inventories to their lower of cost or market. Product gross

##### Table of Contents

profit decreased in fiscal 2009 compared to fiscal 2008. The decrease was primarily due to a lower level of revenue in fiscal 2009. The revenue decline was driven by market and economic
conditions which led to a general decline in capital spending by service providers and more specifically a reduction in the level of orders, primarily from two major customers. Product gross profit was also affected by net inventory provisions of
$3.5 million recorded in fiscal 2009 to adjust inventory carrying values to their lower of cost or market based on anticipated future usage and restructuring costs of $0.4 million associated with certain workforce reductions and facility costs.
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 and gross profit percentage increased in fiscal 2009 compared to fiscal 2008. The year over year dollar and percentage increases relate to a favorable shift in the mix
of higher margin maintenance and support services rendered during fiscal 2009 compared to installation and training 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, other employee related expenses and prototype costs relating to design,
development, testing and enhancements of our products. Research and development expenses increased approximately $2.7 million in fiscal 2009 compared to fiscal 2008 primarily related to increased personnel costs and higher depreciation expense
associated with the expansion of our Shanghai facility. At the beginning of fiscal 2009 we anticipated significant year over year growth in spending for domestic development and expansion of our Shanghai development center and initiated certain
incremental investments. In light of economic and market conditions, which emerged during our first quarter, we slowed our expected pace of development expenditures. As the fiscal year progressed, we recognized that market conditions had worsened
and had given rise to a global economic slowdown in which cutbacks in capital spending by

service providers were generally occurring and expected to continue for some time. In response to these conditions we proceeded cautiously with development spending with a more measured approach
to future offerings. At the beginning of the fourth quarter of fiscal 2009 we initiated actions to reduce workforce and other costs over several quarters. Workforce reductions were then implemented during the fourth quarter with further reductions
implemented at the beginning of fiscal 2010. Due to the timing of the initiated actions, research and development expenses in fiscal 2009 increased, primarily personnel costs, over the fiscal 2008 level. We anticipate that the annualized savings
realized from the cost reduction actions initiated near the end of fiscal 2009, which are estimated to be approximately $12.0 million, will result in substantially lower year over year research and development costs in fiscal 2010.

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 approximately
$6.5 million in fiscal 2009 compared to fiscal 2008. The decrease was primarily due to workforce reductions initiated early in fiscal 2009, as well as lower commission expense on lower revenue, decreased spending for trade shows and lower
amortization of customer evaluation equipment.

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, amortization of intangible assets and other general corporate purposes. General and administrative expenses decreased approximately $7.8 million in fiscal 2009 compared to fiscal 2008. General and
administrative expenses include costs and cost recoveries associated with the now concluded stock option investigation. Cost recoveries in fiscal 2009 totaled $3.7 million while related costs in fiscal 2008 were $1.4 million. Amortization of
purchased intangibles in fiscal 2009 was $1.2 million below fiscal 2008. The remaining year over year reduction relates to workforce and other cost reductions implemented in early fiscal 2009.

Asset Impairments

During
the fourth quarter of fiscal 2009, and in connection with the preparation of its revised plan for fiscal 2010 and its outlook beyond, the Company updated its estimates of future demand for its core and access products. The revised outlook resulted
in a projection of lower discounted cash flows. The Company is continuing with its plan to streamline operations and to pace development efforts with a more measured approach toward future offerings, while maintaining the resources to meet customer
commitments and advance selective new opportunities. Accordingly, the Company conducted an assessment for impairment for its long-lived assets in the fourth quarter of fiscal 2009.

As of June 20, 2009, the last day of our fiscal month June, the Company performed its annual goodwill assessment based on its revised
outlook and discounted cash flow analysis. The assessment indicated that the reporting units fair value was less than its carrying value, including goodwill. The subsequent step required that a valuation be conducted, similar to a purchase
price allocation done in connection with an acquisition, in order to determine the implied fair value of goodwill. Since the Company operates as a single operating unit, the fair value of the intangible assets was determined as part of this
valuation. The result of the valuations determined that the reporting units goodwill and intangible assets were impaired, resulting in a non-cash impairment charge of $20.3 million for goodwill and $2.8 million for intangible assets. In
addition, certain fixed assets were also impaired, resulting in an additional non-cash impairment charge of $1.1 million.

Restructuring

During fiscal 2009, the Company recorded restructuring charges of $4.0 million of which $3.6 million was charged to operating expense and $0.4 million to cost of product revenue. The charges include
workforce reductions primarily in sales, marketing, manufacturing and general administrative functions during the first and second quarters of fiscal 2009 totaling $1.1 million ($0.8 million operating expense and $0.3 million cost of product
revenue). In the fourth quarter of fiscal 2009, the Company announced further workforce reductions. Certain of those workforce reductions, primarily affecting research and development, were completed during the fourth quarter of fiscal 2009
resulting in a charge of $2.3 million. The charge for workforce reductions primarily relates to employee separation packages, which include severance pay, benefits continuation and outplacement costs. In addition, the Company revised its estimate of
rent and other facility costs associated with the consolidation of its New Jersey facility resulting in a charge of $0.6 million. The aggregate fourth quarter fiscal 2009 charge was $2.9 million ($2.8 million charged to operating expense and $0.1
million charged to cost of product revenue). As of July 31, 2009, remaining restructuring payments associated with these actions were $2.5 million.

The remaining workforce reduction actions initiated during the fourth quarter of fiscal 2009 were implemented in August 2009 and will result in a charge of approximately $3.3 million in the first quarter
of fiscal 2010. This charge primarily relates to employee separation packages, which include severance pay, benefits continuation and outplacement costs. In addition, in connection with a decision to exercise the early termination option with regard
to our New Jersey facility lease, we agreed to turn the property back to the lessor in advance of the early termination date in return for the cancellation of an early termination penalty and other consideration. Accordingly, we will also record a
charge of approximately $2.0 million during the first quarter of fiscal 2010 to reflect our non-cancellable lease obligation through the early termination date.

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 in conjunction with the
decision in the fourth quarter of fiscal 2008 to reduce our workforce 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.

We may need to take similar actions in the future.

Interest income decreased in fiscal 2009 compared to fiscal 2008 primarily due to
declining interest rates during the year.

Income Tax Expense

Income tax benefit of $0.2 million was recorded in fiscal 2009 versus an income tax expense of $0.6 million in fiscal 2008. The decrease
primarily resulted from a $0.3 million benefit from the new refundable federal

research and development credit and a $0.3 million benefit from the reversal of the accumulated deferred tax liability recognized from the impairment of the indefinite lived intangible assets.

As a result of incurring substantial net operating losses, 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 and the remainder would be recorded as a reduction in income tax expense.

Total revenue decreased in fiscal 2008 compared to fiscal 2007. 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 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.

Product gross profit

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.

Service gross profit

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.

Research and Development Expenses

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.

Sales and Marketing 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 a termination 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.

General and Administrative
Expenses

General and administrative expenses decreased in fiscal 2008 compared to fiscal 2007. The decrease was primarily
due to lower costs associated with the now concluded stock option investigation. In fiscal 2008 and 2007 we recorded expenses of approximately $1.4 million and $12.0 million, respectively, in connection with investigation matters.

Asset Impairments

During
fiscal year 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 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 the 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.

Reserve for Contingencies

Based on ongoing negotiations and settlement discussions with various tax authorities in 2007, the Company decreased its accrual by $2.2
million, resulting in a reduction of expenses in fiscal 2007. The Company 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.

##### Table of Contents

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.

Liquidity and Capital Resources

Year
Ended July 31, 2009

Total cash, cash equivalents and investments were $926.8 million at July 31, 2009
compared to $941.8 million at July 31, 2008. Included in the July 31, 2009 balances were cash and cash equivalents of $347.7 million, compared to $499.9 million at July 31, 2008. The decrease in cash and cash equivalents of
$152.2 million was attributable to cash used in investing activities of $140.2 million and cash used in operating activities of $12.6 million, partially offset by cash provided by financing activities of $0.6 million.

Net cash used in investing activities was $140.2 million and consisted primarily of net purchase of investments of $135.8 million and
purchases of property and equipment of $4.4 million.

Net cash used in operating activities was $12.6 million. Net loss was
$53.6 million and included non-cash charges including share-based compensation of $4.7 million, an inventory provision of $3.5 million, depreciation and amortization of $12.0 million, and asset impairment charges of $24.2 million. Accounts
receivable increased to $12.9 million at July 31, 2009 from $8.8 million at July 31, 2008. The increase was primarily due to an increase in sales in the fourth quarter. 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 decreased to $16.1 million at July 31, 2009 from $23.8 million at July 31, 2008. The decrease was primarily due to an
increase in inventory reserves and the timing of shipments. Deferred revenue decreased to $15.5 million at July 31, 2009 from $19.1 million at July 31, 2008. The decrease resulted from the recognition of revenue during 2009 of deferred
product shipments and service billings for which revenue recognition criteria was satisfied. These amounts exceeded the level of product shipments and service billings added to the deferred balances as of July 31, 2009.

For the year ended July 31, 2009, net cash provided by financing activities was $0.6 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 $926.8 million at July 31, 2009. 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,
2009, $273.4 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, 2009, more than 67% of our accounts receivable balance was attributable to five of our customers. As of July 31, 2009, we do not have any 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.

##### Table of Contents

As of July 31, 2009 we had accrued restructuring costs of $2.5 million that will be
paid over the next year. In the aggregate, restructuring payments of approximately $7.8 million, including the previously discussed anticipated first quarter of fiscal 2010 charges of $5.3 million, will be paid over the next year.

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.

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 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 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 FSP FAS 142-3 on its consolidated financial statements.

In April 2009, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) FAS 107-1 and Accounting Pronouncement Board (APB) 28-1,
Interim Disclosures about Fair Value of Financial Instruments. This FSP amends Statement of Financial Accounting Standard (SFAS) No. 107, Disclosures About Fair Value of Financial Instruments, to require
disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. This FSP also amends APB Opinion No. 28, Interim Financial Reporting, to
require those disclosures in summarized financial information at interim reporting periods. This FSP is effective for interim reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15,
2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The
Company adopted this FSP in the fourth quarter of fiscal 2009 and it did not have a material impact.

In April 2009, the FASB
issued FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments. This FSP amends the other-than-temporary impairment guidance for debt

securities to make the guidance more operational and to improve the presentation and disclosure of other-than-temporary impairments on debt and equity securities in the financial statements. This
FSP does not amend existing recognition and measurement guidance related to other-than-temporary impairments of equity securities. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with early adoption
permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative disclosures
only for periods ending after initial adoption. The Company adopted this FSP in the fourth quarter of fiscal 2009 and it did not have a material impact.

In April 2009, the FASB issued FSP FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That
Are Not Orderly. This FSP provides additional guidance for estimating fair value in accordance with SFAS No. 157, Fair Value Measurements, (SFAS 157), when the volume and level of activity for the asset or
liability have significantly decreased. This FSP also includes guidance on identifying circumstances that indicate a transaction is not orderly. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with
early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative
disclosures only for periods ending after initial adoption. The Company adopted this FSP in the fourth quarter of fiscal 2009 and it did not have a material impact.

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 at fair value, 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 2009, the FASB issued FSP No. 141R-1, Accounting for Assets Acquired and Liabilities Assumed in a Business Combination
That Arise from Contingencies, (FSP 141R-1). FSP 141R-1 amends the provisions in SFAS No. 141(R), Business Combinations, (SFAS 141R) for the initial recognition and measurement, subsequent measurement
and accounting, and disclosures for assets and liabilities arising from contingencies in business combinations. The FSP eliminates the distinction between contractual and non-contractual contingencies, including the initial recognition and
measurement criteria in SFAS 141R and instead carries forward most of the provisions in SFAS No. 141, Business Combinations, (SFAS 141) for acquired contingencies. FSP 141R-1 is effective for contingent assets and
contingent liabilities acquired in 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 FSP 141R-1 on its consolidated financial statement.

On February 12, 2008, the FASB issued FSP No. 157-2, Effective Date of FASB Statement No 157, which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial
liabilities, except those that are recognized or disclosed at fair value in the financial statements on at least an annual basis until 2009. The

Company adopted FAS 157 beginning August 1, 2008 and deferred the application of SFAS 157 to nonfinancial assets and liabilities until August 1, 2009. The Company is currently
evaluating the potential impact of SFAS 157 on its nonfinancial assets and liabilities.

In May 2009, the FASB issued
statement No. 165, Subsequent Events, (SFAS 165). SFAS 165 modifies the definition of what qualifies as a subsequent eventthose events or transactions that occur following the balance sheet date, but before the
financial statements are issued, or are available to be issuedand requires companies to disclose the date through which it has evaluated subsequent events and the basis for determining that date. We adopted the provisions of SFAS 165 for the
fourth quarter of fiscal 2009 in accordance with the effective date.

In June 2009, the FASB issued SFAS No. 168,
The FASB Accounting Standards CodificationTM and the Hierarchy of Generally Accepted Accounting Principlesa replacement of FASB Statement No. 162, (SFAS 168). The FASB Accounting Standards Codification (the
Codification) will become the source of authoritative U.S. generally accepted accounting principles (U.S. GAAP) on July 1, 2009. The Codification, which changes the referencing of financial standards, is effective for interim or annual
financial periods ending after September 15, 2009. The Codification is not intended to change or alter existing U.S. GAAP. We have evaluated this new statement, and have determined that it will not have a significant impact on the determination
or reporting of our financial results.

In September 2009, the EITF reached final consensus on a new revenue recognition
standard, Issue No. 08-1, Revenue Arrangements with Multiple Deliverables, (EITF 08-1). EITF 08-1 addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, and how
the arrangement consideration should be allocated among the separate units of accounting. This Issue is effective for fiscal years beginning after June 15, 2010 and may be applied retrospectively or prospectively for new or materially modified
arrangements. In addition, early adoption is permitted. The Company is currently evaluating the potential impact of EITF 08-1 on its consolidated financial statements.

In September 2009, the EITF reached final consensus on a new revenue recognition standard, Issue No. 09-3, Applicability of AICPA Statement of Position 97-2 to Certain Arrangements That Contain
Software Elements (EITF 09-3). EITF 09-3 amends the scope of AICPA Statement of Position 97-2, Software Revenue Recognitionto exclude tangible products that include software and non-software components that function together to deliver
the products essential functionality. This Issue shall be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Earlier application is permitted as
of the beginning of a companys fiscal year provided the company has not previously issued financial statements for any period within that year. An entity shall not elect early application of this Issue unless it also elects early application
of Issue 08-1. The Company is currently evaluating the potential impact of EITF 09-3 on its consolidated financial statements.

|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, 2009, the fair value of the portfolio would decline by approximately $0.5 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 35% of total revenue in fiscal 2009. 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. at July 31,
2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period ended July 31, 2009 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, 2009, 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.

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.

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, 2009 and 2008, aggregate cash and cash equivalents and short
and long term investments consisted of (in thousands):

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 service providers 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 evolved, the software component of our product has become 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
applied 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 recognizes revenue when all of the following criteria are met: the Company has persuasive evidence of an arrangement with a customer; the Company delivers the
products; the fee is fixed or determinable 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. Collectability is assessed based on the creditworthiness of the customer as determined by credit checks and the customers payment history to the Company.

##### Table of Contents

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 was incidental to the functionality of the product, the Company 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 collectability 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 was determined in accordance with EITF 00-21, Revenue Arrangements with Multiple Deliverables. When an arrangement involved multiple elements, the entire fee from the arrangement was allocated to each respective element
based on its relative fair value and recognized when revenue recognition criteria for each element was met. Fair value for each element was established based on the sales price charged when the same element was sold separately. If fair value did not
exist for any undelivered element, revenue was not recognized until the earlier of (i) the delivery of the undelivered element or (ii) fair value of the undelivered element existed, unless the undelivered element was a service, in which
case revenue was recognized as the service was performed once the service was 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 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.

Goodwill

As a result of our acquisition of Eastern Research, Inc., the Company recorded goodwill in the amount of $20.3 million. Goodwill is the amount by which the cost of acquired net assets exceeds the fair
value of those net assets on the date of acquisition. The Company allocates goodwill to reporting units at the time of acquisition and bases that allocation on which reporting units will benefit from the acquired assets and liabilities. A reporting
unit is defined as an operating segment or one level below an operating segment, referred to as a component. The Company has determined that it operates as a single reporting unit. The Company assesses goodwill for impairment on an annual basis as
required under Statement of Financial Accounting Standards No. 142, Goodwill and Other Intangible Assets, (SFAS 142) on the last business day of June or more frequently when events and circumstances occur
indicating that the recorded goodwill may be impaired. If the book value of its reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds
the implied fair value, an impairment loss is recorded equal to that excess.

Intangible Assets

Intangible assets resulting from the acquisition of Eastern Research Inc. are accounted for using the purchase method of accounting and are
estimated by management based on the fair value of assets acquired. These intangible assets include acquired technology, customer relationships and trademark. Intangible assets are amortized from one to ten years on a straight-line basis which
represents the estimated periods of benefit.

Impairment of Long-Lived Assets

The Company evaluates the recoverability of its long-lived assets, in accordance with Statement of Financial Accounting Standards
No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS 144) whenever events and changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. This
periodic review may result in an adjustment of estimated depreciable lives or asset impairment. When indicators of impairment are present, the carrying values of the asset are evaluated in relation to its operating performance and future
undiscounted cash flows of the underlying business. If the future undiscounted cash flows are less than the book value, impairment exists. The impairment is measured as the difference between the book value and the fair value of the underlying
asset. Fair values are based on estimates of market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk.

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.

Research and Development and Software Development Costs

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 realization 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 complies with FASB Interpretation 48, Accounting for Uncertainty in Income Taxes (FIN48),
which 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.

Subsequent Event

The Company evaluated the events and transactions subsequent to its July 31, 2009 balance sheet date and in accordance
with SFAS 165 determined that there were no significant events to report through September 29, 2009, which is the date the Company issued its financial statements.

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, 2009, two customers accounted for 19% and 12% of the Companys revenue. 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. 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, 2009 more than 67% of the Companys accounts receivable balance was attributable to five customers. At July 31, 2008, more than 46% 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 Loss Per Share

Basic and diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period less unvested restricted stock. The
following table sets forth the computation of basic and diluted net loss per share (in thousands, except per share data):

Recent Accounting Pronouncements

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 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 FSP FAS 142-3 on its consolidated financial statements.

In April 2009, the Financial Accounting Standards Board (FASB) issued FASB Staff Position (FSP) FAS 107-1 and Accounting Pronouncement Board (APB) 28-1,
Interim Disclosures about Fair Value of Financial Instruments. This FSP amends Statement of Financial Accounting Standard (SFAS) No. 107, Disclosures About Fair Value of Financial Instruments, to require
disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. This FSP also amends APB Opinion No. 28, Interim Financial Reporting, to
require those disclosures in summarized financial information at interim reporting periods. This FSP is effective for interim reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15,
2009. The FSP does not require disclosures for earlier periods presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The
Company adopted this FSP in the fourth quarter of fiscal 2009 and it did not have a material impact.

In April 2009, the FASB
issued FSP FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments. This FSP amends the other-than-temporary impairment guidance for debt securities to make the guidance more operational and to improve
the presentation and disclosure of other-than-temporary impairments on debt and equity securities in the financial statements. This FSP does not amend existing recognition and measurement guidance related to other-than-temporary impairments of
equity securities. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods
presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The Company adopted this FSP in the fourth quarter of fiscal 2009
and it did not have a material impact.

In April 2009, the FASB issued FSP FAS 157-4, Determining Fair Value When the
Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly. This FSP provides additional guidance for estimating fair value in accordance with SFAS No. 157,
Fair Value Measurements, (SFAS 157), when the volume and level of activity for the asset or liability have significantly decreased. This FSP also includes guidance on identifying circumstances that indicate a transaction is
not orderly. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The FSP does not require disclosures for earlier periods
presented for comparative purposes at initial adoption. In periods after initial adoption, this FSP requires comparative disclosures only for periods ending after initial adoption. The Company adopted this FSP in the fourth quarter of fiscal 2009
and it did not have a material impact.

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



59

##### Table of Contents

business combinations. SFAS 141R requires the acquiring entity in a business combination to recognize all assets acquired and liabilities assumed in the transaction at fair value, 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 2009, the FASB issued FSP No. 141R-1, Accounting for Assets Acquired and Liabilities Assumed in a
Business Combination That Arise from Contingencies, (FSP 141R-1). FSP 141R-1 amends the provisions in SFAS No. 141(R), Business Combinations, (SFAS 141R) for the initial recognition and measurement,
subsequent measurement and accounting, and disclosures for assets and liabilities arising from contingencies in business combinations. The FSP eliminates the distinction between contractual and non-contractual contingencies, including the initial
recognition and measurement criteria in SFAS 141R and instead carries forward most of the provisions in SFAS No. 141, Business Combinations, (SFAS 141) for acquired contingencies. FSP 141R-1 is effective for contingent
assets and contingent liabilities acquired in 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 FSP 141R-1 on its consolidated financial statement.

On February 12, 2008, the FASB issued FSP No. 157-2, Effective Date of FASB Statement No 157, which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial
liabilities, except those that are recognized or disclosed at fair value in the financial statements on at least an annual basis until 2009. The Company adopted FAS 157 beginning August 1, 2008 and deferred the application of SFAS 157 to
nonfinancial assets and liabilities until August 1, 2009. The Company is currently evaluating the potential impact of SFAS 157 on its nonfinancial assets and liabilities.

In May 2009, the FASB issued statement No. 165, Subsequent Events, (SFAS 165). SFAS 165 modifies the definition
of what qualifies as a subsequent eventthose events or transactions that occur following the balance sheet date, but before the financial statements are issued, or are available to be issuedand requires companies to disclose the date
through which it has evaluated subsequent events and the basis for determining that date. We adopted the provisions of SFAS 165 for the fourth quarter of fiscal 2009 in accordance with the effective date.

In June 2009, the FASB issued SFAS No. 168, The FASB Accounting Standards CodificationTM and the Hierarchy of Generally Accepted
Accounting Principlesa replacement of FASB Statement No. 162, (SFAS 168). The FASB Accounting Standards Codification (the Codification) will become the source of authoritative U.S. generally accepted accounting
principles (U.S. GAAP) on July 1, 2009. The Codification, which changes the referencing of financial standards, is effective for interim or annual financial periods ending after September 15, 2009. The Codification is not intended to
change or alter existing U.S. GAAP. We have evaluated this new statement, and have determined that it will not have a significant impact on the determination or reporting of our financial results.

In September 2009, the EITF reached final consensus on a new revenue recognition standard, Issue No. 08-1, Revenue Arrangements
with Multiple Deliverables, (EITF 08-1). EITF 08-1 addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, and how the arrangement consideration should be allocated among the
separate units of accounting. This Issue is

effective for fiscal years beginning after June 15, 2010 and may be applied retrospectively or prospectively for new or materially modified arrangements. In addition, early adoption is
permitted. The Company is currently evaluating the potential impact of EITF 08-1 on its consolidated financial statements.

In
September 2009, the EITF reached final consensus on a new revenue recognition standard, Issue No. 09-3, Applicability of AICPA Statement of Position 97-2 to Certain Arrangements That Contain Software Elements (EITF 09-3). EITF 09-3
amends the scope of AICPA Statement of Position 97-2, Software Revenue Recognitionto exclude tangible products that include software and non-software components that function together to deliver the products essential functionality.
This Issue shall be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. Earlier application is permitted as of the beginning of a companys fiscal
year provided the company has not previously issued financial statements for any period within that year. An entity shall not elect early application of this Issue unless it also elects early application of Issue 08-1. The Company is currently
evaluating the potential impact of EITF 09-3 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.

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.

During the
fourth quarter of fiscal 2009, and in connection with the preparation of its revised plan for fiscal 2010 and its outlook beyond, the Company updated its estimates of future demand for its core and access products. The revised outlook resulted in a
projection of lower discounted cash flows. The combination of current business, economic and market conditions, together with our current estimate of future demand and the resultant cost reduction actions initiated during our fourth quarter,
combined to give rise to an impairment in the carrying value of the Companys goodwill and intangible assets during the fourth quarter of fiscal 2009. The Company recorded an impairment charge of $20.3 million for the entire carrying value of
goodwill and an impairment charge of $2.8 million for the remaining carrying value of identified 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

Massachusetts.

In accordance with the requirements of SFAS 144, the Company is required to test certain long-lived assets
when indicators of impairment are present. During the fourth quarter of fiscal 2009, and in connection with the preparation of its revised plan for fiscal 2010 and its outlook beyond, the Company updated its estimates of future demand for its core
and access products. The revised outlook resulted in a projection of lower discounted cash flows. The Company concluded an assessment for impairment should be conducted for its long-lived assets in the fourth quarter of fiscal 2009. The Company
determined that the carrying value of certain fixed assets exceeded their fair value. As a result, the Company recorded an impairment charge of $1.1 million in the fourth quarter of fiscal 2009 to write down certain fixed assets to their estimated
fair value.

|6. | Goodwill and Intangible Assets
|-- | ------------------------------

As a result of its acquisition of Eastern Research, Inc., the Company recorded goodwill in the amount of $20.3 million. This amount represented 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 our fiscal month June each year. The Company also tests
goodwill between annual tests if an event occurs or circumstances change that indicate that the fair value of the reporting unit may be below its carrying value. The Company also reviews other long-lived assets, including purchased intangibles, for
impairment whenever events or changes in circumstances indicate that the carrying amount of the assets or asset group may not be recoverable in accordance with SFAS 144.

Goodwill impairment is determined using a two-step process. The first step involves a comparison of the estimated fair value of a reporting
unit to its carrying amount, including goodwill. In performing the first step, the Company determines the fair value of a reporting unit using a discounted cash flow (DCF) analysis. Determining fair value requires the exercise of
significant judgment, including judgments about appropriate discount rates, perpetual growth rates, and the amount and timing of expected future cash flows. Discount rates are based on a weighted average cost of capital (WACC), which
represents the average rate a business must pay its providers of debt and equity. The WACC used to test goodwill is derived from a group of comparable companies. The cash flows employed in the DCF analysis are derived from internal earnings and
forecasts and external market forecasts. If the estimated fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not necessary. If the carrying
amount of the reporting unit exceeds its estimated fair value, then the second step of the goodwill impairment test must be performed. The second step of the goodwill impairment test compares the implied fair value of the reporting units
goodwill with its carrying amount of goodwill to measure the amount of impairment loss, if any. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination, whereby the estimated
fair value of the reporting unit is allocated to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value of the reporting
unit was the purchase price paid. If the carrying amount of the reporting units goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.

During the fourth quarter of fiscal 2009, and in connection with the preparation of its revised plan for fiscal 2010 and its outlook beyond,
the Company updated its estimates of future demand for its core and access products. The revised outlook resulted in a projection of lower discounted cash flows. The Company is continuing with its plan to streamline operations and to pace
development efforts with a more measured approach toward future offerings, while maintaining the resources to meet customer commitments and advance selective new opportunities. Accordingly, the Company determined that for its single reporting unit
the carrying amount of its net assets exceeded its fair value, indicating that a potential impairment existed. After completing the second step of the goodwill impairment test, the Company recorded a goodwill impairment charge during the fourth
quarter of 2009 of $20.3 million.

The changes in the carrying amount of goodwill during the year ended July 31, 2009 and
2008 were as follows:

Intangible Assets

In accordance with the requirements of SFAS 144, the Company is required to test certain long-lived assets when indicators of impairment are present. For the purposes of the SFAS 144 test, long-lived
assets are grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. During the fourth quarter of fiscal 2009, and in connection with
the preparation of its revised plan for fiscal 2010 and its outlook beyond, the Company updated its estimates of future demand for its core and access products. The revised outlook resulted in a projection of lower discounted cash flows. The Company
concluded an assessment for impairment should be conducted for its intangible assets in the fourth quarter of fiscal 2009. The Company tested the long-lived assets in question for recoverability by comparing the sum of the undiscounted cash flows
attributable to each respective asset group to their carrying amounts, and determined that the carrying amounts were not recoverable. Management then evaluated the fair values of each long-lived asset of the potentially impaired long-lived asset
group to determine the amount of the impairment, if any. The fair value of each intangible asset was based primarily on an income approach, which is a present value technique used to measure the fair value of future cash flows produced by the asset.
The Company estimated future cash flows over the remaining useful life of each intangible asset. As a result of this analysis, the Company determined that its intangible assets related to completed technology, and customer relationships, had
carrying values that exceeded their estimated fair values. As a result, an impairment charge of $2.8 million was recorded in fourth quarter of 2009.

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.

Components of the Companys acquired intangible assets are comprised of the following:

Substantially all of the income (loss) before income taxes as shown in the Consolidated
Statement of Operations for the years ended July 31, 2009, 2008 and 2007 is derived in the United States. Certain foreign wholly owned subsidiary companies are compensated on a cost plus basis resulting in the recognition of foreign taxable
income and tax expense.

During the years ended July 31, 2009, 2008 and 2007 the Company did not record a current tax
benefit for the net operating losses due to the Companys substantial losses.

At July 31, 2009, the Company had
federal and state net operating loss (NOL) carryforwards of approximately $768.1 million and $186.6 million, respectively. The federal and state net operating loss carryforwards will expire at various dates through 2029. The Company also
had federal and state research and development credit carryforwards of approximately $11.0 million and $10.5 million, respectively, which begin to expire in 2020 and 2014, respectively.

The occurrence of ownership changes, as defined in Section 382 of the Internal Revenue Code, as amended, is 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 realization of its deferred tax assets and has established a
valuation allowance of approximately $353.6 million for such assets, which are comprised principally of net operating loss carryforwards, research and development credits and stock based compensation. The Company recorded an increase to the
valuation allowance of $12.2 million and a decrease to the valuation allowance of $3.7 million for the years ended July 31, 2009 and July 31, 2008, respectively, which offset the change in the net deferred tax assets. The increase in the
valuation allowances for the year ended July 31, 2009 was the result of significant realized net operating losses, increased non deductible reserves and tax credits balances. 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.

In
accordance with SFAS 142 and as a result of the fiscal year 2007 acquisition of Eastern Research, the Company had recorded a valuation allowance in excess of its net deferred tax assets. The excess was computed based on the difference between the
book and tax basis of indefinite lived intangible assets that was not expected to reverse during the net operating loss carryforward period. For the fiscal year ended July 31, 2009, the Company wrote off its indefinite lived intangibles
resulting in a $0.3 million deferred tax benefit from the reversal of the accumulated deferred tax liability.

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, 2009, the Company had net operating loss carryforwards of approximately $5.9 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 $2.2 million will be credited to additional paid-in capital when the Company recognizes a cash savings.

At August 1, 2008, the Company had provided a liability of $1.2 million for unrecognized tax benefits related to various foreign income
tax matters. As of July 31, 2009, the total amount of unrecognized tax liability is $1.3 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.

As of July 31, 2009, the total amount of accrued interest and penalties is $0.3
million As of July 31, 2008, the Company had accrued $0.2 million of interest and penalties related to uncertain tax positions. The Company accounts for interest and penalties related to uncertain tax positions as part of its provision for
federal, international, and state income taxes.

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 2009, 2008 and 2007. Estimates of fair value are not intended to predict actual future events or the value ultimately
realized by persons who receive equity awards.

During fiscal year 2007 the Company modified the terms of certain equity
awards for a former executive to allow for continued vesting and approximately 75 employees to allow additional time to exercise the awards. As a result of these modifications, the Company recorded additional non-cash, stock-based compensation
expense of $2.3 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:



|                               |  |           |  |           |  |

|Risk-free interest rate (4)    |  | 2.2%      |  | 3.8%      |  | 4.7%     
|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 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 has outstanding equity awards issued under several legacy equity plans and equity plans assumed as result of previous acquisitions, including the 1998 Stock Incentive Plan (the 1998
Plan), the 1999 Stock Incentive Plan (the 1999 Plan), the Sirocco 1998 Stock Option Plan, the Eastern Research, Inc. Stock Option Plan, and the 1999 Non-employee Director Stock Option Plan (the 1999 Director Plan).
Although each of these equity incentive plans remains in effect and has awards outstanding, upon stockholder approval of the Companys 2009 Stock Incentive Plan (the 2009 Plan) and the Companys 2009 Non-employee Director Stock
Option Plan (the 2009 Director Plan), the Board has committed to make future equity awards exclusively from the 2009 Plan and the 2009 Director Plan, each as described below.

2009 Stock Incentive Plan

The 2009 Plan was approved by the Companys
Board on November 10, 2008 and became effective upon the approval of the Companys stockholders on January 6, 2009. The 2009 plan has a ten year term. The 2009 Plan reserves 28,000,000 shares of common stock for issuance of awards,
subject to increase by the number of shares granted under the Companys 1998 and 1999 Plans that are not exercised or are forfeited, lapse or expire to the extent such shares would otherwise again have been available for issuance under such
plans. In addition, any shares subject to an award granted under the 2009 Plan that are not exercised or are forfeited, lapse or expire also will be available for future grants of awards under the 2009 Plan. The number of shares available for
issuance under the 2009 Plan is subject to adjustment in the event of a merger, stock split, stock dividend, and certain other changes in capitalization.

The 2009 Plan authorizes grants of awards including incentive stock options, nonqualified
stock options, restricted stock, restricted stock units, performance awards and other awards to officers, directors, employees and consultants of the Company. Subject to certain restrictions, the Compensation Committee of the Board has broad
discretion to (i) interpret and construe the relevant provisions of the 2009 Plan, (ii) to determine which individuals are eligible to receive awards under the Plan and (iii) to determine the terms and conditions for awards under the
Plan, including the number of shares, vesting conditions and any required service criteria. Under the 2009 Plan, stock options may not be granted with an exercise price less than the fair market value of the underlying shares of commons stock on the
date of grant. Option awards have a maximum term of ten years and generally vest over a three to five year period. Certain change in control transactions may cause awards granted under the 2009 Plan to vest at an accelerated rate unless the awards
are assumed or substituted for in connection with the transaction. As of July 31, 2009 a total of 29,148,833 shares were available for grant under the 2009 Plan.

2009 Non-employee Director Stock Option Plan

On January 6, 2009, our
stockholders also approved the Companys 2009 Director Plan, which is a formula plan to provide stock options to the Companys non-employee directors. Each non-employee director, upon initial appointment as a director, is granted an option
to purchase 90,000 shares of common stock which vests over three years and, immediately following each annual meeting of stockholders, is automatically granted an option to purchase 30,000 shares of common stock which vests on the earlier of the
next annual meeting of stockholders or one year. These stock options are the only awards that may be granted to non-employee directors under the 2009 Director Plan.

The 2009 Director Plan reserves 1,200,000 shares of common stock for issuance of awards, subject to increase by the number of shares granted under the Companys 1999 Director Plan that are not
exercised, expire or otherwise terminate to the extent such shares would otherwise again be available for issuance under the 1999 Director Plan. In addition, shares subject to an option granted under the 2009 Director Plan that are not exercised,
expire or otherwise terminate without delivery of any common stock subject thereto also will be available for future grants of stock options under the 2009 Director Plan. Our Compensation Committee of the Board administers the 2009 Director Plan
and, subject to certain restrictions contained in the Plan, has the power to construe it and to adopt rules and regulations for the administration of the Plan. Stock options under the 2009 Director Plan have a maximum ten year term and may not be
granted with an exercise price less than the fair market value of the underlying shares of common stock on the date of grant. Certain change in control transactions will cause awards granted under the 2009 Plan to vest at an accelerated rate unless
the awards are assumed or substituted for in connection with the transaction. At July 31, 2009, 1,110,000 shares were available for grant under the 2009 Director Plan.

##### Table of Contents

The weighted average fair value of stock options granted on dates of grant was $1.25, $1.80
and $2.15 during fiscal years 2009, 2008 and 2007, respectively.

The intrinsic value of stock options exercised, calculated
as the difference between the market value of the shares on the exercise date and the exercise price of the option, was $0.7 million, $2.8 million and $1.7 million for fiscal years 2009, 2008 and 2007, respectively.

The total cash received from employees as a result of employee stock option exercises during fiscal years 2009, 2008 and 2007 was $0.6
million, $10.9 million and $2.7 million, respectively.

As of July 31, 2009, there was $7.4 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 2.6 years.

Restricted Stock

Restricted stock may be
issued to employees, officers, directors and consultants of the Company. 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, 2009 and 2007.

The following table summarizes the status of the Companys
nonvested restricted shares since July 31, 2008:

The total fair value of shares vested during fiscal 2009, 2008 and 2007 was
approximately $760 thousand, $553 thousand and $1 thousand, respectively.

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. At July 31, 2009 the Company held no shares of treasury stock and also repurchased 17,416
shares and retired 22,417 shares of treasury stock at its acquisition cost of $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 $0.7 million, $0.8 million and
$0.8 million were made to the plan during fiscal 2009, 2008 and 2007, respectively.

12.    Restructuring Charges

During fiscal 2009, the Company recorded restructuring charges of $4.0 million of which $3.6 million was charged to operating
expense and $0.4 million to cost of product revenue. The charges include workforce reductions primarily in sales, marketing, manufacturing and general administrative functions during the first and

second quarters of fiscal 2009 totaling $1.1 million ($0.8 million operating expense and $0.3 million cost of product revenue). In the fourth quarter of fiscal 2009, the Company announced further
workforce reductions. Certain of those actions, primarily affecting research and development, were completed during the fourth quarter of fiscal 2009 resulting in a charge of $2.3 million. The charge for workforce reductions primarily relates to
employee separation packages, which include severance pay, benefits continuation and outplacement costs. In addition, the Company revised its estimate of rent and other facility costs associated with the consolidation of its New Jersey facility
resulting in a charge of $0.6 million. The aggregate fourth quarter fiscal 2009 charge was $2.9 million ($2.8 million charged to operating expense and $0.1 million charged to cost of product revenue). As of July 31, 2009, remaining
restructuring payments associated with these actions were $2.5 million.

The remaining workforce reduction actions initiated
during the fourth quarter of fiscal 2009 were implemented in August 2009 and will result in a charge of approximately $3.3 million in the first quarter of fiscal 2010. This charge primarily relates to employee separation packages, which include
severance pay, benefits continuation and outplacement costs. In addition, in connection with a decision to exercise the early termination option with regard to our New Jersey facility lease, we agreed to turn the property back to the lessor in
advance of the early termination date in return for the cancellation of an early termination penalty and other consideration. Accordingly, we will also record a charge of approximately $2.0 million during the first quarter of fiscal 2010 to reflect
our non-cancellable lease obligation through the early termination date.

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 in conjunction with the decision in the fourth quarter of fiscal 2008 to reduce our workforce 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.

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.

We may need to take similar steps in the
future.

As of July 31, 2009, remaining future cash payments associated with these actions
approximated $2.5 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):

13.    Fair Value Measurements

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements, (SFAS 157), which is effective for fiscal years
beginning after November 15, 2007 and for interim periods within those years. This statement defines fair value, establishes a framework for measuring fair value and expands the related disclosure requirements. This statement applies under
other accounting pronouncements that require or permit fair value measurements. The statement indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal
market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. SFAS 157 defines fair value based upon an exit price model.

Relative to SFAS 157, the FASB issued FASB Staff Positions (FSP) 157-1 and 157-2. FSP 157-1 amends SFAS 157 to exclude SFAS No. 13,
Accounting for Leases, (SFAS 13) and its related interpretive accounting pronouncements that address leasing transactions, while FSP 157-2 delays the effective date of the application of SFAS 157 to fiscal years beginning after
November 15, 2008 for all non-financial assets and non-financial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis.

The Company adopted SFAS 157 as of August 1, 2008, with the exception of the application of the statement to non-recurring
non-financial assets and non-financial liabilities. Non-recurring non-financial assets and non-financial liabilities for which we have not applied the provision of SFAS 157 include those measured at fair value in goodwill impairment testing,
indefinite lived intangible assets measured at fair value for impairment testing, asset retirement obligations initially measured at fair value, and those initially measured at fair value in a business combination.

SFAS 157 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of
unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:



|        |  |                                                                                                                                                                                                                                                                                                       
|------- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 1 |  | Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset and liability occur in
sufficient frequency and volume to provide pricing information on an ongoing basis.                                 
|        | 
|Level 2 |  | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are
observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
|        | 
|Level 3 |  | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Cash Equivalents

Cash equivalents of $348 million consisting of money market funds and federal government and government agency obligations are classified
within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

Available-For-Sale Securities

Available-for-sale securities of $579 million consisting of federal government
and government agency obligations are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

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), which is effective for fiscal years beginning after November 15, 2007. 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. 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. On August 1, 2008, the Company adopted SFAS 159 and has elected not to measure any additional financial instruments and other items at fair value.

14.    Commitments and Contingencies

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. 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.

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. On October 10, 2008, the Court
granted Plaintiffs request to withdraw, without prejudice, their motion for class certification.

On April 3, 2009,
the Plaintiffs submitted to the Court a motion for preliminary approval of a settlement of the approximately 300 coordinated cases, which includes the Company, the underwriter defendants in its class action lawsuit, and the plaintiff class in its
class action lawsuit. The insurers for the issuer defendants in the coordinated cases will make the settlement payment on behalf of the issuers, including the Company. The settlement is subject to termination by the parties under certain
circumstances, and is subject to Court approval. The final settlement hearing was held on September 10, 2009. To date, the Court has not issued a ruling on the settlement.

Due to the inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of the matter. If the settlement
is not approved or the parties terminate the settlement, the litigation continues, 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 claimed, 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 sought 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. The Federal Action did
not seek affirmative relief from the Company. On May 1, 2009, the Massachusetts Court approved the plaintiffs voluntary dismissal of the Federal Action without prejudice, except as to demand futility, which was dismissed with prejudice.

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 (District Court) 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. The District Court found the motions appropriate for oral argument which was held on January 6, 2009. On March 16, 2009, the District Court issued an order dismissing the case. On March 31, 2009, the plaintiff
appealed, and the Appeals Court established a briefing schedule. The Company is named as a nominal defendant. No recovery is sought from the Company in this matter.

Other Matters

On June 29, 2006, a former employee of the Company
filed a complaint against the Company and the Companys Chief Executive Officer 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. Appellate briefing was completed on May 1, 2009. Oral argument has been scheduled for October 14, 2009.

From time to time the Company is a party to litigation and other disputes which we consider routine and incidental to our business. Management does not expect the results of any of these actions to have a material adverse effect on our
business, results of operations or financial condition.

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, 2009, 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, 2009 or July 31, 2008 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 $0.01 million, $2.1 million and $2.4 million for fiscal years 2009, 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, 2009 or July 31, 2008. The Company maintains insurance policies whereby certain payments may be recoverable subject to the terms
and conditions provided in such policies. During fiscal 2009, the Company received $3.7 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.

The following table summarizes the activity related to the product warranty
liability (in thousands):

|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, 2009. 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.

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, 2009. 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, 2009, our internal control over financial reporting was effective
based on those criteria.

The Companys independent registered public accounting firm, PricewaterhouseCoopers LLP, has
audited the effectiveness of the Companys internal control over financial reporting as of July 31, 2009, as stated in their report that appears on page 48 of this Form 10-K.

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.
