TO OUR SHAREHOLDERS


     Fiscal 2000 was a pivotal year for Vitesse Semiconductor Corporation. In
addition to posting record financial results for the sixth consecutive year, we
made excellent progress executing our strategy shift to position us as a leading
"complete solutions" provider of integrated circuits (ICs) for the optical
Internet infrastructure. In a year of notable accomplishments, other highlights
included:

     [_]  Revenues in our key communications business unit grew by 75% over
fiscal 1999. In fiscal 2000, this burgeoning segment represented 89% of our
total revenue compared to 81% in fiscal 1999.

     [_]  We improved gross profit margins by moving the Company toward a
higher complexity, high performance product line, as well as achieving greater
fabricating efficiencies.

     [_]  We made vitally important acquisitions - Orologic and SiTera - to
provide the backbone of our network processor strategy, as well as the WAN
products group of Philips Semiconductor to extend our core telecom product line.

     [_]  We expanded our customer base by nearly 50% while reducing our
dependence on any single customer. Our largest customer, Lucent Optical Network
Group, accounted for 15% of revenue in fiscal 2000, compared to 18% and 23% in
fiscal 1999 and 1998, respectively.

     [_]  We introduced comprehensive reference designs for high-speed
physical layer circuits, network processors and switch fabrics to support our
complete solutions strategy.

     [_]  We commenced full-scale production of our OC192 (10 Gb/s) product
line, and began development of a proprietary technology for OC768 (40 Gb/s)
physical layer products.

RECORD RESULTS, FINANCIAL STRENGTH

     Revenue in fiscal 2000 was a record $441.7 million, an increase of 57% from
prior year's revenue of $281.7 million. Over the past five years, our revenues
have grown at a compounded average rate of 60%. Gross margins improved from 63%
in fiscal 1999 to 66% in fiscal 2000 as a result of increased fab utilization in
Colorado Springs and improved manufacturing yields. Our operating income,
excluding the effects of acquisition costs and goodwill, grew to $153.6 million
in fiscal 2000 from $80.7 million in fiscal 1999, a 90% increase. Diluted
earnings per share, also excluding the effects of acquisition costs and
goodwill, increased from $0.34 per share in fiscal 1999 to $0.62 per share in
fiscal 2000 or an increase of 82%.

     Our financial condition remains extremely strong and liquid. In addition to
cash provided by operations, in March 2000, we raised net proceeds of $718
million through the issuance of $720 million of our 4% convertible subordinated
debentures due 2005. At fiscal year end, we had amassed cash and investments
totaling approximately $922 million. This balance sheet strength provides us
with the flexibility and financial resources to successfully execute the total
solutions strategy.

STRATEGY: COMPLETE SOLUTIONS

     Over the past 18 to 24 months, our management team has been tightly focused
on implementing a major realignment of our strategic direction. Now
substantially complete, this blueprint positions us to capitalize on the
fundamental change underway in the communications infrastructure equipment
market. Our strategy is based on the belief that shorter product life cycles and
ever more intense "time to market" pressures will require both established and
emerging optical infrastructure equipment suppliers to utilize complete chip
sets supplied and verified as a unit by a single component supplier. This is in
stark contrast with equipment manufacturers' historical practices - which
continue today - of purchasing individual components from multiple sources,
augmenting them with custom circuits and debugging each chip interface
internally. Competitive pressures will cause manufacturers to increasingly seek
a single source for complete solutions and we stand ready to supply their
requirements.

PRODUCTS

     In fiscal 2000, we devoted substantial resources to developing the circuits
needed to create complete reference designs in three areas of the network: the
transmission core, the intelligent edge, and the storage area network.

     The network core has been our traditional focus area. This market is
dominated by the need to transmit large amounts of optical data at very high
data rates for moderate to very long distances. In fiscal 2000, data rates in
the core increased from 2.5 Gb/s to 10 Gb/s. By the end of fiscal 2001, we
expect to see initial deployments of systems with 40 Gb/s data rates.

     To address the needs of the core we have developed a family of 10 Gb/s
physical layer products, framers, pointer processors, forward error correction
(FEC) circuits and switch fabrics. FEC circuits enable systems to improve their
performance by efficiently encoding signals and then recovering the signals
after they have been significantly degraded by the attenuation and

                                   page no. 09
                                               VITESSE SEMICONDUCTOR CORPORATION
                                       AR 2000
<PAGE>

dispersion of long distance fibers. The use of ever more efficient FEC circuits
dramatically reduces the cost of a system by eliminating or reducing costly
optical regeneration and amplification stations along the network. Under
development are more sophisticated FEC circuits using proprietary Vitesse
algorithms and circuits meeting the newly established "digital wrapper"protocols
that we believe will become the next generation long-haul transmission standard.

     Products that address the network core application accounted for 54% of
revenue and grew 65% compared to 1999. In 2001, we plan to extend our product
line further through the Philip WAN Products Group acquisition and continued
internal investment.

Significant among such new products are:

-------------------------------------------------------------------------------

  The VSC7990 - a 10.7 Gb/s Laser Diode Driver which by virtue of its
  superlative edge rates and drive current enables efficient design of an OC-192
  optical transmitter.

  The VSC8171/VSC8172 - a 10Gb/s SONET/SDH multiplexer/demultiplexer chip set
  that combines a clock generator and a clock recovery unit for use in OC-192
  systems.

  The VSC9116 - an OC-192 SONET/SDH transport overhead terminating transceiver
  that may be used to combine four OC-48 data streams into a single OC-192 data
  stream and also provide OC-192 overhead processing for performance monitoring
  applications.

  The VSC9142 - a dual mode OC-48 Packet/ATM framing device that can be used in
  equipment interconnecting IP data over public or private SONET/SDH networks or
  in equipment interconnecting enterprise ATM switches. This highly integrated
  0.18 micron CMOS device provides a complete low-power physical layer solution
  for Packet/ATM over SONET/SDH.

  The VSC9184 - a bidirectional OC-48 or quad OC-12 Pointer Processor and Frame
  Aligner. This device can be used in SONET/SDH applications such as large TSI
  switches, digital cross connects and add/drop multiplexers.

-------------------------------------------------------------------------------

     The intelligent edge of the network manages the data aggregation and
sorting with multiple protocols - including Ethernet, Asynchronous Transfer Mode
(ATM), and Internet Protocol (IP) - and quality of service needs (such as real-
time video). In this portion of the network, the system provider must be able to
reconfigure the network on an as-needed basis to meet rapidly changing needs.
Thus, flexible but powerful programmable processors that can analyze and
reconfigure individual data packets are essential in order to avoid either
multiple types of port cards or regular hardware upgrades. Traditionally, this
segment of the optical network has been dominated by large established suppliers
developing nearly all of the communication circuits as custom circuits.

     This situation is changing rapidly. Over the past year, as we and others
have developed numerous standard products, the market has seen the formation of
a multitude of startup companies to address this portion of the network. This
market segment has recently upgraded its speed requirements to 2.5 Gb/s and will
be moving to 10 Gb/s in early 2002. For two reasons we foresee this portion of
the network as our greatest growth potential. First, this market has moved to
data rates high enough to be in our "sweet spot" of existing products and
expertise. Second, we do not have to battle established suppliers because most
prior generation systems used customer designed ASICs. Time-to-market
requirements and a scarcity of qualified design engineers renders the full
custom approach ineffective.

     In the intelligent edge of the network, our "complete solution" approach of
physical layer, processor, and switch fabric has found fertile ground. As the
first complete supplier for this application, we have already won numerous total
solution wins among the startups. Moreover, among the established suppliers, the
need to reduce cycle times - along with the best of class performance of our
network processors and switch fabrics - has enabled us to win several
significant designs, even as they continue to design a portion of the solution
as custom circuits. We expect this segment of the market to be a significant
catalyst of growth by mid-2001.

Some of the new products include:

-------------------------------------------------------------------------------

  The PaceMaker 2.4 - a highly integrated cell/packet traffic management engine
  with state of the art Quality of Service features supporting full OC-48 data
  rates.

  The IQ2000 - a highly programmable and scalable family of network processors
  designed to deliver flexible, wire-speed deep-packet processing solutions at
  speeds up to 2.5 Gb/s. The programmability of these processors enables
  functional evolution with the emergence or revision of standards.

  The VSC9182 - a 64 x 64 STS-12 Time Slot Interchange Switch that grooms
  multiple SONET/SDH tributaries at the STS-1 level and provides 40 Gb/s of STS-
  1 connectivity.

-------------------------------------------------------------------------------

     Storage Area Networks (SAN), currently based on Fibre Channel, are rapidly
being upgraded from data rates of 1 Gb/s to 2 Gb/s. To enable this market, we
have introduced our initial 2 Gb/s products that provide complete disk chip set
solutions along with best-in-class signal quality. These products keep us in the
forefront of the burgeoning networked storage market. Our SAN solutions are used
by leading providers such as EMC, Sun Microsystems and

Hewlett Packard. Looking forward, the SAN product group will augment their
current market by expanding into Networked Attached Storage (NAS), Storage over
Ethernet (iSCSI) and InfiniBand. Some of the significant SAN products introduced
this year include:

-------------------------------------------------------------------------------

  The VSC7217 - a quad 8-bit parallel-to-serial and serial-to-parallel
  transceiver chip for high bandwidth interconnection between buses, backplanes,
  or other subsystems. Four Fibre Channel and Gigabit Ethernet compliant
  transceivers provide up to 8.32 Gb/s of duplex raw data transfer.

  The VSC7130 - a dual repeater/retimer for Fibre Channel (1.0625 Gb/s) and
  Gigabit Ethernet (1.25 Gb/s) systems to provide bi-directional Clock and Data
  Recovery (CDR).

  The VSC7148 - a device that contains all the functions needed to implement an
  entire daisy-chainable 1.0625 Gb/s Fibre Channel JBOD Loop for storage systems
  containing up to sixteen disk drives. This device is typically used in
  distributing Fibre Channel signals to an array of disk drives in managed and
  un-managed arrays.

-------------------------------------------------------------------------------

     During fiscal 2000, we continued to strengthen our market position by
introducing over 50 new standard products, establishing a formidable barrier to
entry by our competitors. These include products fabricated with a variety of
technologies matched to optimize the product's performance. These process
technologies include our proprietary H-GaAs process, as well as commercially
available "foundry" technologies such as CMOS and Silicon Germanium (SiGe). Our
product portfolio now consists of over 100 standard products with an anticipated
average production life span of four to five years with some products
approaching their tenth year of production.

TECHNOLOGY

     In the most recent year, we began shipping our initial H-GaAs V products
for 10 Gb/s applications. This process offers superior device performance
characteristics compared to current SiGe technology.

     In order to meet the needs of 40 Gb/s and 80 Gb/s products in 2001 and
beyond, we are developing an even higher performance process based on Indium
Phosphide (InP) Heterojunction Bipolar Transistor (HBT) technology. The InP HBT
technology will be established on our four-inch line in Camarillo, California,
with our six-inch line in Colorado Springs, Colorado supplying the bulk of our
GaAs production.

     The combination of two proprietary internally manufactured process
technologies combined with two commercial "foundry" processes (CMOS and SiGe)
places us in a unique position of utilizing the best technology for any
individual product. On a competitive basis, none of our competitors have a
process barrier that prevents us from competing with them, whereas in some of
our product lines we can supply either unique or superior products based on
process technology.

SUMMARY AND OUTLOOK

     We enter the new fiscal year with much anticipation. Our complete solutions
strategy - strengthened by acquisitions and internal product development - is
largely complete. We have the resources - both engineering talent and
financial -to capitalize on the fundamental shifts currently taking place among
systems manufacturers. With an extensive number of new products on the horizon,
which will augment what is already the industry's broadest line, the future
holds tremendous promise.

     In closing, let me thank our employees for their unflagging dedication, the
board of directors for its sound guidance and our customers for their loyalty
and support. To you, our shareholders, I express gratitude for your commitment
and support as we embark on an exciting new chapter in our corporate history.

MANAGEMENT'S DISCUSSION AND OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


The following discussion of the financial condition and results of operations of
Vitesse Semiconductors Corporation and subsidiaries ("Vitesse" or the "Company")
should be read in conjunction with the Consolidated Financial Statements and
Notes thereto included elsewhere in this Annual Report. All historical financial
information has been restated to reflect the acquisitions that were accounted
for as pooling-of-interests transactions (see Note 2 to the Consolidated
Financial Statements). The information set forth in "Management's Discussion and
Analysis of Financial Condition and Results of Operations" below includes
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933 as amended and Section 21E of the Exchange Act that involve risks
and uncertainties, including statements regarding amortization of intangible
assets, interest expense, research and development expense, profitability and
the ability to use net operating loss carryforwards and tax credits, and
liquidity and capital resources. Factors that realistically could cause results
to differ materially from those projected in the forward-looking statements are
set forth in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Factors Affecting Future Operating Results."

OVERVIEW

We are a leading supplier of high-performance integrated circuits ("ICs")
targeted principally at systems manufacturers in the communications markets.
Over the past few years, the proliferation of the Internet and the explosive
growth in the volume of data being sent over local and wide area networks has
placed a tremendous strain on the networking infrastructure. The demand for
increased bandwidth has resulted in a need for both faster as well as more
expansive networks. Additionally, there has also been a growing trend towards
the outsourcing of IC design and manufacture by systems companies to suppliers
of ICs such as Vitesse. These and other factors have led to an increasing demand
for high performance ICs.

We are also a supplier of ICs to other markets such as the automatic test
equipment ("ATE") market. In fiscal 2000, sales of communications and ATE
products represented 89% and 11%, respectively, of our total revenues.

We have focused our sales efforts on a relatively small number of systems
manufacturers who require high-performance ICs. Sales to our 10 largest
customers represented approximately 61%, 66% and 69% of total revenues in fiscal
2000, 1999 and 1998, respectively.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS


As of September 30, 2000, we had $101.5 million and $63.1 million of federal and
state net operating loss carryforwards, respectively, which will be recoverable
only if future taxable income is sufficient to utilize such tax loss
carryforwards. Based on historical results of operations, estimated future
taxable income and other factors, we believe that it is more likely than not
that the tax benefits associated with such loss carryforwards will be realized.
See Note 6 to the Consolidated Financial Statements.

     In fiscal 2000, we completed acquisitions of Orologic, Inc. ("Orologic") in
exchange for $450.0 million of our common stock, SiTera Incorporated ("SiTera")
in exchange for $750.0 million of our common stock and several other companies
for an aggregate of approximately $36.5 million in stock options assumed and
cash. With the exception of SiTera, all acquisitions in fiscal 2000 have been
accounted for using the purchase method of accounting. As a result, an aggregate
of $478.2 million in goodwill and other identifiable intangible assets will be
amortized over 2 to 7 years. In connection with the acquisitions in fiscal 2000,
we also recorded $23.0 million in unearned compensation on stock options which
will be amortized over the vesting period of the stock options.While we
frequently evaluate potential acquisitions of business, products or technologies
that we believe will contribute to our strategy, we do not currently have any
binding commitments with respect to any material acquisitions.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

YEAR ENDED SEPTEMBER 30, 2000, AS COMPARED TO YEAR ENDED SEPTEMBER 30, 1999

REVENUES  Revenues in fiscal 2000 were $441.7 million, a 57% increase over the
$281.7 million recorded in fiscal 1999. The increase in total revenues was due
to a unit growth in shipments of existing products as well as the introduction
of new products to customers in the communications markets.

COST OF REVENUES  Cost of revenues as a percentage of total revenues in fiscal
2000 was 34.1% compared to 37.2% in fiscal 1999. The decrease in cost of
revenues as a percentage of total revenues resulted primarily from a reduction
in per unit costs associated with increased utilization of our Colorado Springs
wafer fabrication facility as well as improved manufacturing yields at both the
Colorado Springs and Camarillo wafer fabrication facilities.

ENGINEERING, RESEARCH AND DEVELOPMENT  Engineering, research and development
expenses were $86.2 million in fiscal 2000 compared to $57.3 million in fiscal
1999. The increase was principally due to increased headcount, primarily from
acquisitions, and higher costs to support our continuing efforts to develop new
products. Our engineering, research and development costs are expensed as
incurred. We intend to continue to increase the absolute dollar amount of
engineering, research and development expenses in the future. As a percentage of
total revenues, engineering, research and development expenses were 19.5% in
fiscal 2000 and 20.4% in fiscal 1999.

SELLING, GENERAL AND ADMINISTRATIVE  Selling, general and administrative
expenses were $51.1 million in fiscal 2000 compared to $38.9 million in fiscal
1999. The increase was principally due to increased compensation and travel
costs resulting from recent acquisitions, and increased legal and accounting
fees. As a percentage of total revenues, selling, general and administrative
expenses declined to 11.6% in fiscal 2000 from 13.8% in fiscal 1999.

ACQUISITION RELATED COSTS  Acquisition related costs consists of amortization of
goodwill and other identifiable intangible assets, purchased in-process research
and development ("IPRD"), and amortization of unearned compensation and other
acquisition related costs. Amortization of goodwill and other identifiable
intangible assets was $39.9 million in fiscal 2000, compared with $1.2 million
in fiscal 1999. Amortization of goodwill and other identifiable intangible
assets primarily relates to various purchase acquisitions (see Note 2 to the
Consolidated Financial Statements). Amortization of goodwill and purchased
intangible assets will increase to the extent we acquire companies and
technologies.

Purchased IPRD of $45.6 million for fiscal 2000 arose from the purchase of
Orologic, completed in fiscal 2000 (see Note 2 to the Consolidated Financial
Statements). Purchased IPRD was expensed upon acquisition because technological
feasibility had not been established and no further alternative uses existed.
The estimated fair value of these projects was determined by use of a discounted
cash flow model. The value of the in-process technology was calculated by
identifying research projects in areas for which technological feasibility had
not been established, estimating the resulting net cash flows from such
products, discounting the net cash flow to present value, and applying the
reduced percentage completion of the projects thereto.

The estimated net cash flows span a three to six year period. These net cash
flows were discounted back to their present value using a factor that takes into
account the risks surrounding the successful development of the purchased in-
process technology. The discount rate used in calculating the present value of
the IPRD was 20% and was based on the risk profile of the acquired assets.

Key assumptions used in the analysis of the in-process projects primarily
consist of an expected completion date for the in-process projects, estimated
costs to complete the projects, and revenue and expense projections once the
products have entered the market.  Shipment volumes of products from the
acquired technologies are not material to our overall financial results at the
present time.  Therefore, it is difficult to determine the accuracy of overall
revenue projections early in the technology or product life cycle. Failure to
achieve the expected levels of revenue and net income from these products will
negatively impact the return on investment expected at the time that acquisition
was completed and potentially result in impairment of any other assets related
to the development activities.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

Included in acquisition related costs is the amortization of unearned
compensation and other acquisition related costs such as legal and accounting
fees of $4.0 million and $3.3 million, respectively, in fiscal 2000.

OTHER INCOME, NET.  Other income consists of interest income, net of interest
and other expenses.  Interest income increased to $39.4 million for the year
ended September 30, 2000, from $11.0 million in the prior year. Interest expense
was $18.5 million for the year ended September 30, 2000, compared to a minor
amount in the prior year. The increase in interest income is due to higher
average cash, short-term investments, long-term investments and long-term
deposit balances resulting from increased profitability and proceeds received
from the convertible debenture offering (see Note 4 to the Consolidated
Financial Statements). Increased interest expense relates to the debentures and
amortization of debt issue costs.  As a result of the convertible debenture
offering, we expect to record interest expense of approximately $8.1 million per
quarter in future periods.

INCOME TAXES.  We recorded a provision for income taxes in the amount of $53.8
million in fiscal 2000 and $29.3 million in fiscal 1999. The actual effective
tax rate for fiscal 2000 and 1999 was 66% and 32%, respectively. Excluding the
effects of the Orologic acquisition, the fiscal 2000 effective income tax rate
was 33%.

YEAR ENDED SEPTEMBER 30, 1999, AS COMPARED TO YEAR ENDED SEPTEMBER 30, 1998

REVENUES  Revenues in fiscal 1999 were $281.7 million, a 55% increase over the
$181.2 million recorded in fiscal 1998. The increase in total revenues was due
to a unit growth in shipments of existing products, as well as the introduction
of new products to customers in the communications and ATE markets.

COST OF REVENUES  Cost of revenues as a percentage of total revenues in fiscal
1999 was 37.2% compared to 39.4% in fiscal 1998. The decrease in cost of
revenues as a percentage of total revenues resulted primarily from a reduction
in per unit costs associated with increased utilization of our Colorado Springs
wafer fabrication facility, as well as improved manufacturing yields at both the
Colorado Springs and Camarillo wafer fabrication facilities.

ENGINEERING, RESEARCH AND DEVELOPMENT  Engineering, research and development
expenses were $57.3 million in fiscal 1999 compared to $37.0 million in fiscal
1998. The increase was principally due to increased headcount and higher costs
to support our continuing efforts to develop new products. As a percentage of
total revenues, engineering, research and development expenses were 20.4% in
fiscal 1999 and 1998.

SELLING, GENERAL AND ADMINISTRATIVE  Selling, general and administrative
expenses were $38.9 million in fiscal 1999 compared to $25.8 million in fiscal
1998. The increase was principally due to increased headcount, higher
commissions earned by sales representatives resulting from increased sales, and
increased advertising costs. As a percentage of total revenues, selling, general
and administrative expenses declined to 13.8% in fiscal 1999 from 14.3% in
fiscal 1998.

ACQUISITION RELATED COSTS  Acquisition related costs consists of amortization of
goodwill and other identifiable intangible assets of $1.2 million and $0 in
fiscal 1999 and 1998, respectively.  Amortization of goodwill and other
identifiable intangible assets primarily relates to various acquisitions (see
Note 2 to the Consolidated Financial Statements).

OTHER INCOME, NET  Other income consists of interest income, net of interest and
other expenses. Other income increased to $11.0 million in fiscal 1999 from $9.6
million in fiscal 1998 due to a higher average cash, short-term investments and
long-term deposit balances in fiscal 1999 as compared to fiscal 1998 resulting
primarily from positive cash flow and profitability.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

INCOME TAXES  We recorded a provision for income taxes in the amount of $29.3
million in fiscal 1999 and $7.9 million in fiscal 1998, representing effective
tax rates of 32% and 14%, respectively. The increase in the effective tax rate
is due to the full utilization in prior years of available net operating loss
carryforwards.

LIQUIDITY AND CAPITAL RESOURCES

OPERATING ACTIVITIES  We generated $152.4 million, $79.3 million and $41.5
million from operating activities in fiscal 2000, 1999 and 1998, respectively.
The increase in cash from operations was principally due to an improvement in
profitability, excluding the one time non-cash charge of $45.6 million relating
to purchased IPRD in fiscal 2000.

INVESTING ACTIVITIES  We used $719.3 million, $112.9 million and $87.3 million
in investing activities for the years ended September 30, 2000, 1999, and 1998,
respectively. The increase in cash used in investing activities for fiscal 2000
was primarily due to the net investment of $586.9 million in held to maturities
debt and equity securities, from the proceeds received from the convertible
subordinated debentures offering. Capital expenditures, primarily for
manufacturing and test equipment, were $90.0 million, $44.5 million and $32.0
million in fiscal 2000, 1999 and 1998, respectively. As further discussed in
Note 2 to the Consolidated Financial Statements, we also paid $34.0 million and
$13.0 million in cash for the purchase of companies during fiscal 2000 and 1999,
respectively.

As a result of increased demand for our products, we have been increasing
capacity at our Colorado Springs manufacturing facility.  The majority of the
costs associated with increasing capacity were financed through various
operating lease transactions (see Note 9 to the Consolidated Financial
Statements). We intend to continue investing in new manufacturing, test and
engineering equipment.

FINANCING ACTIVITIES  In fiscal 2000, we generated $734.0 million of cash from
financing activities. We received $702.0 million from convertible subordinated
debentures, net of issuance costs, $5.4 million of proceeds from term loans,
$28.8 million of proceeds from the issuance of common stock pursuant to our
stock option and stock purchase plans, $1.5 million from capital contributions
by minority interest limited partners and $1.5 million from the elimination of
duplicate period of pooled companies. This was partially offset by $5.1 million
in repayments of debt obligations. In fiscal 1999, we generated $38.3 million of
cash from financing activities consisting of $2.9 million of proceeds from term
loans, $37.5 million of proceeds from the issuance and sale of common stock, and
proceeds from the issuance of common stock pursuant to our stock option and
stock purchase plans, and $0.8 million from the elimination of duplicate period
of pooled companies. This was partially offset by $2.9 million in repayments of
debt obligations.

We have an agreement with a bank for a revolving line of credit which expires on
January 15, 2001. The maximum amount available under the revolving line of
credit is $12.5 million. The interest rate on the borrowings under this line of
credit is equal to the bank's prime rate (see Note 4 to the Consolidated
Financial Statements).

We believe that our cash and cash equivalents, short-term investments, cash flow
from operations and revolving line of credit agreement are adequate to finance
our planned  growth and operating needs for next 12 months.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

At September 30, 2000, our long-term debt consists of convertible subordinated
debentures with interest at a fixed rate. Consequently, we do not have
significant cash flow exposure on our long-term debt.

IMPACT OF RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No.133"). SFAS No. 133 will require recognition
of all derivatives as either assets or liabilities on the balance sheet at fair
value. We will adopt SFAS No. 133, as amended by SFAS No. 137, in the first
quarter of our fiscal year ending September 30, 2001. At this time we do not
expect the adoption of this standard will have a material effect on our
consolidated financial statements.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
101"). SAB 101, as amended, summarizes certain of the SEC's views of applying
generally accepted accounting principles to revenue recognition in financial
statements. At this time, we do not expect the adoption of SAB 101 to have a
material effect on our operations or financial position.  We are required to
adopt SAB 101 in the fourth quarter of fiscal 2001.

FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS
WE ARE DEPENDENT ON A SMALL NUMBER OF CUSTOMERS IN A FEW INDUSTRIES

We intend to continue focusing our sales effort on a small number of customers
in the communications and automatic test equipment markets that require high-
performance integrated circuits. Some of these customers are also our
competitors. For the fiscal year ended September 30, 2000, our largest customer
accounted for 15% of our total revenues and no other customer accounted for more
than 10% of our total revenues. If any of our major customers delays orders of
our products or stops buying our products, our business and financial condition
would be severely affected.

OUR OPERATING RESULTS MAY FLUCTUATE

Our quarterly revenues and expenses may fluctuate in the future. These
variations may be due to a number of factors, many of which are outside our
control. Factors that could affect our future operating results include the
following:

     .  The loss of major customers

     .  Variations, delays or cancellations of orders and shipments of our
        products

     .  Reduction in the selling prices of our products

     .  Significant changes in the type and mix of products being sold

     .  Delays in introducing new products

     .  Design changes made by our customers

     .  Our failure to manufacture and ship products on time

     .  Changes in manufacturing capacity, the utilization of this capacity and
        manufacturing yields

     .  Variations in product and process development costs

     .  Changes in inventory levels; and

     .  Expenses or operational disruptions resulting from acquisitions

In the past, we have recorded significant new product and process development
costs because our policy is to expense these costs at the time that they are
incurred. We may incur these types of expenses in the future. In future periods,
we expect a substantial increase in amortization of intangible assets resulting
from recent acquisitions and interest expense resulting from recent financing
activities. These additional expenses will have a material and adverse effect on
our earnings in future periods. The occurrence of any of the above mentioned
factors could have a material adverse effect on our business and on our
financial results.

WE HAVE LIMITED MANUFACTURING CAPACITY AND WE DEPEND ON A NEW PRODUCTION
FACILITY

During 1998, we started producing high-performance integrated circuits at our
new six-inch wafer fabrication factory in Colorado Springs, Colorado. We are
faced with several risks in the successful operation of this facility as well as
in our overall production operations. We had only produced finished four-inch
wafers until 1998 and therefore we have limited experience with the equipment
and processes involved in producing finished six-inch wafers. We do not have
excess production capacity at our Camarillo plant to offset failure of the new
Colorado facility to meet production goals. Further, some of our products have
been qualified for manufacture at only one of the two facilities. Consequently,
our failure to successfully operate the new facility could severely damage
financial results.

We also must now effectively coordinate and manage two facilities. We have
limited experience in managing production facilities located at two different
sites, and our failure to successfully do so could have a material adverse

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

HERE ARE RISKS ASSOCIATED WITH RECENT AND FUTURE ACQUISITIONS

In fiscal 2000, we made two significant strategic acquisitions. In March 2000,
we completed the acquisition of Orologic in exchange for approximately 4.6
million shares of our common stock. In May 2000, we completed the acquisition of
SiTera in exchange for approximately 14.7 million shares of our common stock.
Also in 2000, we have completed two smaller acquisitions for an aggregate of
approximately $36.5 million in stock options assumed and cash. These
acquisitions may result in the diversion of management's attention from the day-
to-day operations of the Company's business. Risks of making these acquisitions
include difficulties in the integration of acquired operations, products and
personnel. If we fail in our efforts to integrate recent and future
acquisitions, our business and operating results could be materially and
adversely affected.

In addition, acquisitions could result in dilutive issuances of equity
securities, substantial debt, and amortization expenses related to goodwill and
other intangible assets. In particular, in connection with our acquisition of
Orologic, we were required to expense in-process research and development of
$45.6 million in fiscal 2000. Further, we expect to amortize an aggregate of
approximately $441.0 million of goodwill and other identifiable intangible
assets over the next 2 to 6 years. We do not currently have any binding
obligations with respect to any particular material acquisition; however, our
management frequently evaluates strategic opportunities available. In the future
we may pursue additional acquisitions of complementary products, technologies or
businesses.

OUR INDUSTRY IS HIGHLY COMPETITIVE

The high-performance semiconductor market is extremely competitive and is
characterized by rapid technological change, price erosion and increased
international competition. We compete directly or indirectly with the following
categories of companies:

     .  High-performance integrated circuit suppliers such as Hewlett Packard,
        Broadcom, Conexant, Intel, Motorola, Lucent Technologies, PMC Sierra and
        Applied Micro Circuits Corporation

     .  Internal integrated circuit manufacturing units of systems companies
        such as Lucent Technologies, Fujitsu and Cisco Systems.

Our current and prospective competitors include many large companies that have
substantially greater marketing, financial, technical and manufacturing
resources than we do.

Competition in the markets that we serve is primarily based on prices,
performance, product quality and the ability to deliver products in a timely
fashion. Product qualification is typically a lengthy process and some
prospective customers may be unwilling to invest the time or expense necessary
to qualify suppliers such as Vitesse. Prospective customers may also have
concerns about the relative advantages of our products compared to more familiar
silicon-based semiconductors. Further, customers may also be concerned about
relying on a relatively small company for a critical sole-sourced component. To
the extent we fail to overcome these challenges, there could be material and
adverse effects on our business and financial results.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATONS


THERE IS RISK ASSOCIATED WITH DOING BUSINESS IN FOREIGN COUNTRIES

In fiscal 2000, international sales accounted for 24% of our total revenues, and
we expect international sales to constitute a substantial portion of our total
revenues for the foreseeable future. International sales involve a variety of
risks and uncertainties, including risks related to:

     .  Reliance on strategic alliance partners
     .  Compliance with foreign regulatory requirements
     .  Variability of foreign economic conditions
     .  Changing restrictions imposed by U.S. export laws, and
     .  Competition from U.S. based companies that have firmly established
significant international operations

Failure to successfully address these risks and uncertainties could adversely
affect our international sales, which could in turn have a material and adverse
effect on our results of operations and financial condition.

WE MUST KEEP PACE WITH PRODUCT AND PROCESS DEVELOPMENT AND TECHNOLOGICAL CHANGE

The market for our products is characterized by rapid changes in both product
and process technologies. We believe that our success to a large extent depends
on our ability to continue to improve our product and process technologies and
to develop new products and technologies in order to maintain our competitive
position. Further, we must adapt our products and processes to technological
changes and adopt emerging industry standards. Our failure to accomplish any of
the above could have a negative impact on our business and financial results.

WE ARE DEPENDENT ON KEY SUPPLIERS

We manufacture our products using a variety of components procured from third-
party suppliers. Most of our high-performance integrated circuits are packaged
by third parties. Other components and materials used in our manufacturing
process are available from only a limited number of sources. Any difficulty in
obtaining sole- or limited-sourced parts or services from third parties could
affect our ability to meet scheduled product deliveries to customers. This in
turn could have a material adverse effect on our customer relationships,
business and financial results.

OUR MANUFACTURING YIELDS ARE SUBJECT TO FLUCTUATION

Semiconductor fabrication is a highly complex and precise process. Defects in
masks, impurities in the materials used, contamination of the manufacturing
environment and equipment failures can cause a large percentage of wafers or die
to be rejected.  Manufacturing yields vary among products, depending on a
particular high-performance integrated circuit's complexity and on our
experience in manufacturing it. In the past, we have experienced difficulties in
achieving acceptable yields on some high-performance integrated circuits, which
has led to shipment delays. Our overall yields are lower than yields obtained in
a mature silicon process because we manufacture a large number of different
products in limited volume and our process technology is less developed.  We
anticipate that many of our current and future products may never be produced in
volume.

Since a majority of our manufacturing costs are relatively fixed, maintaining a
number of shippable die per wafer is critical to our operating results. Yield
decreases can result in higher unit costs and may lead to reduced gross profit
and net income. We use estimated yields for valuing work-in-process inventory.
If actual yields are materially different than these estimates, we may need to
revalue work-in-process inventory. Consequently, if any of our current or future
products experience yield problems, our financial results may be adversely
affected.

OUR BUSINESS IS SUBJECT TO ENVIRONMENTAL REGULATIONS

We are subject to various governmental regulations related to toxic, volatile
and other hazardous chemicals used in our manufacturing process. Our failure to
comply with these regulations could result in the imposition of fines or in the
suspension or cessation of our operations. Additionally, we may be restricted in
our ability to expand operations at our present locations or we may be required
to incur significant expenses to comply with these regulations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATONS


OUR FAILURE TO MANAGE GROWTH MAY ADVERSELY AFFECT US

The management of our growth requires qualified personnel, systems and other
resources. In particular, the continued operation of the new facility in
Colorado Springs and its integration with the Camarillo facility will require
significant management, technical and administrative resources. Additionally, we
have recently established several product design centers worldwide. Finally, we
acquired Vermont Scientific Technologies, Inc., ("VTEK"), in November 1998,
Serano Systems Corporation ("Serano") in January 1999, XaQti Corporation
("XaQti") in July 1999, Orologic in March 2000, SiTera in May 2000, certain
assets and liabilities of Kalman Saffran Associates, Inc., ("KSA") in June 2000
and certain assets and liabilities of Philips Semiconductors, Inc. ("Philips")
in August 2000, and we have only limited experience in integrating the
operations of acquired businesses. Failure to manage our growth or to
successfully integrate new and future facilities or newly acquired businesses
could have a material adverse effect on our business and financial results.

WE ARE DEPENDENT ON KEY PERSONNEL

Due to the specialized nature of our business, our success depends in part upon
attracting and retaining the services of qualified managerial and technical
personnel. The competition for qualified personnel is intense. The loss of any
of our key employees or the failure to hire additional skilled technical
personnel could have a material adverse effect on our business and financial
results.

OUR ABILITY TO REPURCHASE OUR DEBENTURES, IF REQUIRED, WITH CASH UPON A CHANGE
OF CONTROL MAY BE LIMITED

In certain circumstances involving a change of control or the termination of
public trading of our common stock, holders of the debentures may require us to
repurchase some or all of the debentures. We cannot assure you that we will have
sufficient financial resources at such time or will be able to arrange financing
to pay the repurchase price of the debentures.

Our ability to repurchase the debentures in such event may be limited by law, by
the indenture, by the terms of other agreements relating to our senior debt and
by such indebtedness and agreements as may be entered into, replaced,
supplemented or amended from time to time. We may be required to refinance our
senior debt in order to make such payments. We may not have the financial
ability to repurchase the debentures if payment of our senior debt is
accelerated.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS  Vitesse Semiconductor Corporation was incorporated
under the laws of Delaware on February 3, 1987. Vitesse Semiconductor
Corporation is a leader in the design, development, manufacturing and marketing
of high-performance integrated circuits.

PRINCIPLES OF CONSOLIDATION  The consolidated financial statements include the
accounts of Vitesse Semiconductor Corporation and its wholly owned subsidiaries
and its majority controlled joint venture (collectively, the "Company").
Minority interest represents the limited partners' proportionate share of the
equity of Vitesse Venture Fund, L.P. The minority interest impact is reflected
in minority interest in (income) loss of the joint venture and is the limited
partners' share of the majority controlled joint venture operations. As more
fully described in Note 2, the Company's acquisition of SiTera on May 31, 2000
was accounted for under the pooling-of-interests method, and accordingly, all
periods prior to the acquisitions have been restated to include the accounts and
results of operations of SiTera for all periods presented. All significant
intercompany accounts and transactions have been eliminated in consolidation.

REVENUE RECOGNITION  Production revenue is recognized when products are shipped
to customers. Revenue from development contracts is recognized upon attainment
of specific milestones established under customer contracts. Revenue from
products deliverable under development contracts, including design tools and
prototype products, is recognized upon delivery. Costs related to development
contracts are expensed as incurred.

CASH EQUIVALENTS AND INVESTMENTS  The Company considers all highly liquid
investments with original maturities of three months or less to be cash
equivalents. Cash equivalents and investments are principally composed of money
market accounts and obligations of the U.S. government and its agencies.
Pursuant to Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities" (SFAS No. 115), the Company
classifies its securities included under investments as held-to-maturity
securities, which are recorded at amortized cost, adjusted for the amortization
or accretion of premiums or discounts. As of September 30, 2000 and 1999,
carrying value was substantially the same as market value.

INVENTORIES  Inventories are stated at the lower of cost (determined by the
first-in, first-out method) or market (net realizable value). Costs associated
with the development of a new product are charged to engineering, research and
development expense as incurred until the product is proven through testing and
acceptance by the customer. Inventories are shown net of a valuation reserve of
$12.7 million and $6.7 million at September 30, 2000 and 1999, respectively.

DEPRECIATION AND AMORTIZATION  Property and equipment are stated at cost less
accumulated depreciation and are depreciated on a straight-line basis over the
estimated useful lives of the assets. Such lives vary from 3 to 5 years.
Goodwill and other intangibles are carried at cost less accumulated
amortization, which is being provided on a straight-line basis over the economic
useful lives of the respective assets, generally 5 to 15 years.

INCOME TAXES  The Company accounts for income taxes pursuant to the provisions
of Financial Accounting Standards Board Statement No. 109. Under the asset and
liability method of Statement No. 109, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases and operating loss and tax credit carryforwards.

RESEARCH AND DEVELOPMENT COSTS  The Company charges all research and development
costs to expense when incurred. Manufacturing costs associated with the
development of a new fabrication process or a new product are expensed until
such times as these processes or products are proven through final testing and
initial acceptance by the customer

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

COMPUTATION OF NET INCOME PER SHARE The reconciliation of shares used to
calculate basic and diluted income per share consists of the following (in
thousands):

                                                       2000      1999       1998
                                                  ------------------------------
Shares used in basic per share computations -
     weighted average shares outstanding            176,147   164,602    153,735
Net effect of dilutive common share equivalents
     based on treasury stock method                  13,681    13,710     13,112
                                                  ------------------------------
Shares used in diluted per share computations       189,828   178,312    166,847

Common stock equivalents to purchase 6,476,562, 165,364 and 53,490 shares that
were outstanding at September 30, 2000, 1999 and 1998, respectively, were not
included in the computation of diluted net income per share, as their effect
would have been antidilutive. The antidilutive common stock equivalents at
September 30, 2000 consist primarily of the convertible subordinated debentures
that are convertible into the Company's common stock at a conversion price of
$112.19.

FINANCIAL INSTRUMENTS  The Financial Accounting Standards Board's Statement of
Financial Accounting Standards No. 107, "Disclosures about Fair Value of
Financial Instruments," defines fair value of a financial instrument as the
amount at which the instrument could be exchanged in a current transaction
between willing parties. The Company's carrying value of cash equivalents,
short-term investments, restricted long-term deposits, accounts receivable,
long-term investments, accounts payable and term loans approximates fair value
because the instrument has a short-term maturity or because the applicable
interest rates are comparable to current borrowing rates of those instruments.

LONG-LIVED ASSETS  The Company reviews long-lived assets and certain
identifiable intangibles for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future undiscounted operating
cash flows expected to be generated by the asset. If such assets are considered
to be impaired, the impairment to be recognized is measured by the amount by
which the carrying amount of the assets exceeds the fair value of the assets.

ACCOUNTING FOR STOCK OPTIONS  The company applies the intrinsic value-based
method of accounting prescribed by Accounting Principles Board (APB) Opinion No.
25, "Accounting for Stock Issued to Employees," and related interpretations, in
accounting for employee stock options. As such, compensation expense would be
recorded on the date of grant only if the current market price of the underlying
stock exceeded the exercise price. Compensation expense related to stock options
granted to non-employees is accounted for under Statement of Financial
Accounting Standards (SFAS) No. 123, "Accounting for Stock-based Compensation,"
whereby compensation expense is recognized over the vesting period based on the
fair value of the options on the date of grant.

In March 2000, the Financial Accounting Standards Board issued FASB
Interpretation No. 44. "Accounting for Certain Transactions involving Stock
compensation" ("FIN 44"). FIN 44 provides guidance for issues arising in
applying APB Opinion No. 25, "Accounting for Stock Issued to Employees." FIN 44
applies specifically to new awards, exchanges of awards in a business
combination, modification to outstanding awards, and changes in grantee status
that occur on or after July 1, 2000, except for the provisions related to
repricings and the definition of an employee which apply to  award issued after
December 15, 1998. Application of FIN 44 did not have a material affect on the
Company's financial reporting.

COMPREHENSIVE INCOME  On October 1, 1998 the Company adopted Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income." This
statement establishes standards for reporting and display of comprehensive
income and its components in a full set of general-purpose financial statements.
The Company has no components of other comprehensive income. Therefore,
comprehensive income is the same as the reported net income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SEGMENT REPORTING  On October 1, 1998 the Company adopted Statement of Financial
Accounting Standards No. 131, "Disclosure about Segments of an Enterprise and
Related Information." This statement establishes standards for reporting
operating segment information in annual financial statements and interim reports
issued to stockholders. The Company operates in only one segment, as defined by
SFAS No. 131. Geographic information is included in Note 7.

USE OF ESTIMATES  Management of the Company has made a number of estimates and
assumptions relating to the reporting of assets and liabilities to prepare these
financial statements in conformity with generally accepted accounting
principles. Actual results could differ from those estimates.

RECLASSIFICATIONS AND RESTATEMENTS  Certain reclassifications have been made to
the prior year financial statements to conform to the current year presentation.

On September 15, 1999, the Company's Board of Directors announced a 2 for 1
stock split of common stock effected in the form of a stock dividend to
shareholders of record as of September 30, 1999. On April 22, 1998, the
Company's Board of Directors announced a 2 for 1 stock split of the common stock
effected in the form of a stock dividend to shareholders of record as of May 4,
1998.  Accordingly, historical share, per share, stock option amounts and share
prices have been restated to reflect retroactively the stock splits.

NOTE 2 - BUSINESS COMBINATIONS

POOLING-OF-INTERESTS BUSINESS COMBINATIONS
On May 31, 2000, the Company issued 14,698,288 shares of its common stock in
exchange for all of the outstanding shares of SiTera, a pioneer in intelligent
network processing for service provider, carrier edge, and large enterprise
markets.

On July 16, 1999 the Company issued 1,892,300 shares of its common stock in
exchange for all of the outstanding shares of XaQti, a provider of integrated
circuits for the data communication industry.

On January 21, 1999 the Company issued 655,256 shares of its common stock in
exchange for all of the outstanding shares of Serano, a provider of enclosure
platform management solutions for Fibre Channel and SCSI server and storage
subsystems.

These acquisitions were accounted for as poolings-of-interests in fiscal 2000
and 1999; therefore, all prior periods presented have been restated.

The results of operations previously reported by the separate enterprises, and
combined amounts presented in the accompanying consolidated financial
statements, are summarized below (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Additionally, there were significant other changes to shareholders' equity for
the separate entities for the periods before the combinations which include
SiTera's issuance of 4,677,683 shares of common stock for $14.0 million in 1999,
and SiTera's issuance of 5,323,970 shares of common stock for $10.0 million,
XaQti's issuance of 801,666 shares of common stock for $9.0 million, and
Serano's issuance of 117,786 shares of common stock for $1.2 million in 1998.

Certain reclassifications have been made to the financial statements of SiTera,
Serano and XaQti to conform to the Company's financial presentation.

Prior to the combination, both Serano's and XaQti's fiscal years ended on
December 31 and SiTera's fiscal year ended October 31. In recording the pooling-
of-interests combination, Serano's and XaQti's financial statements for the year
ended December 31, 1998 were combined with the Company's financial statements
for the year ended September 30, 1998. SiTera's financial statements for the
years ended October 31, 1999 and 1998, were combined with the Company's
financial statements for the years ended September 30, 1999, and 1998. For the
year ended September 30, 2000 the results of SiTera have been included herein,
resulting in a duplication of operations for the period from October 1, 1999 to
October 31, 1999. As a result, the Company has eliminated the related loss of
$1.5 million from retained earnings for fiscal 2000. For the year ended
September 30, 1999 the results of XaQti and Serano have been included herein,
resulting in a duplication of operations for the period from October 1, 1998 to
December 31, 1998. As a result, the Company has eliminated the related loss of
$0.8 million from retained earnings for fiscal 1999.

</TABLE>

In December 1999, the Company entered into a $5 million loan agreement with two
lenders, available for draw down in increments of $1 million through March 31,
2000. Interest is based on the three year U.S. Treasury rate plus a spread of
7.49%, with a maximum rate of 15% per annum, payable monthly. Principal payments
are due monthly in payments equal to 3.33% of the loan plus interest over a
period of 30 months, commencing June 2000. As of September 30, 2000, the Company
had drawn down the maximum funds under the loan agreement or approximately $5
million.

On December 23, 1998, the Company obtained a 1.5 million line of credit and a
1.75 million equipment financing facility. The line of credit became due and was
paid in full in July 1999. The interest rate on the equipment financing
facility, which is secured by equipment purchased by the Company under this
facility, is based on a variable interest rate that will have a lower and upper
cap ranging from 7.25% to 12.5% per annum. Principal and interest is payable
monthly on amounts borrowed by the Company under the equipment financing
facility. In connection with these agreements, warrants to purchase a total of
63,349 shares of common stock were issued to the lenders at an initial exercise
price of $1.89 per share. The warrants were valued using the Black-Scholes
option pricing model. As a result, the Company recorded approximately $85,000 of
debt issuance costs, which are being amortized to interest expense over the
corresponding term of the related line of credit and equipment financing
facility.

The Company has a $12.5 million revolving line of credit agreement with a bank,
which expires in January 2001. The agreement provides for interest to be paid
monthly at the bank's prime rate (9.50% on September 30, 2000). The Company must
adhere to certain requirements and provisions to be in compliance with the terms
of the agreement and is prohibited from paying dividends without the consent of
the bank. As of September 30, 2000 and 1999, no amounts were outstanding under
the line of credit.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 5 - SHAREHOLDERS' EQUITY
PREFERRED STOCK  In fiscal 1991, the Board of Directors authorized 10,000,000
shares of undesignated preferred stock.

COMMON STOCK  In 1999, the Company's shareholders approved an increase in the
number of authorized shares of common stock from 250,000,000 to 500,000,000. All
of the following data has been restated for the effects of all stock splits.

EMPLOYEE STOCK PURCHASE PLAN The Company has an employee stock purchase plan for
all eligible employees. Under the plan, employees may purchase shares of the
Company's common stock at six-month intervals at 85% of the lower of the fair
market value at the beginning and end of each interval. Employees purchase such
stock using payroll deductions and annual contributions which may not exceed 20%
of their compensation, including commissions and overtime, but excluding
bonuses. In fiscal 2000, 1999 and 1998, 179,786, 196,740 and 234,726 shares,
respectively, were issued under the plan at average prices of $32.08, $17.99,
and $9.55."At September 30, 2000, 1,165,628 shares were reserved for future
issuance.

STOCK OPTION PLANS  The Company has in effect several stock-based plans under
which non-qualified and incentive stock options have been granted to employees.
Options generally vest and become exercisable at the rate of 25% per year. The
exercise price of all stock options must be at least equal to the fair market
values of the shares of common stock on the date of grant. The term of options
is generally 10 years.

In August 1991, following shareholder approval, the Company adopted a stock
option plan for non-employee directors (the "Director's Plan"). Under the plan,
annually on January 1 each non-employee director will be granted a non-statutory
option to purchase 60,000 shares of common stock (except in the case of the
Chairman of the Board who shall receive an option to purchase 90,000 shares).
The options have a 10-year term and vest at the rate of 2% per month.

Pursuant to the Company's 1991 Stock Options Plan, the number of shares reserved
under the Plan automatically increases by a number of shares equal to 3.5% of
the Company's common stock outstanding at the end of each fiscal year. Under all
stock option plans, a total of 25,806,533 shares of common stock have been
reserved for issuance as of September 30, 2000 (which increased to 32,108,353
effective October 1, 2000 pursuant to the terms of the 1991 Plan) and 2,182,429
(which increased to 8,484,249 effective October 1, 2000 pursuant to the terms of
the 1991 Plan) remained available for future grant.

Activity under the employee stock option plans and Director's Plan for fiscal
2000, 1999 and 1998 is as follows:

The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123,"Accounting for Stock Based Compensation." The
Company used the Black-Scholes option pricing model to value stock options for
pro forma presentation. The assumptions used to estimate the value of options
granted under the various stock option plans and the shares under the Employee
Stock Purchase Plan are as follows:

The pro forma amounts reflect compensation expense related to 2000, 1999 and
1998 stock option grants and shares issued under the employees stock purchase
plan. Because the pro forma compensation cost for stock options is recognized
over the four-year vesting period, the foregoing pro forma reductions in the
Company's net income are not representative of the anticipated amounts in future
years.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

In assessing the realizability of deferred tax assets, management considered
whether it is more likely than not that some portions or all of the deferred tax
assets will be realized. The ultimate realization of deferred tax assets is
dependent on the generation of future taxable income during the periods in which
those temporary differences become deductible. Based on the level of historical
taxable income and projections for future taxable income over the periods in
which the deferred tax assets are deductible, management believes that it is
more likely than not that the results of future operations will generate
sufficient taxable income to realize the net deferred tax assets.

During fiscal 2000, the Company recognized tax benefits associated with employee
stock options aggregating $66.2 million. Such benefits have been recorded
directly to shareholders' equity.

During fiscal 2000, the Company recorded deferred tax assets of $2.4 million in
connection with its purchase of Orologic.

Consolidated U. S. income before taxes was $61.2 million, $75.4 million, $56.6
million for the years ended September 30, 2000, 1999 and 1998, respectively. The
corresponding income before taxes for non U. S. based operations was $20.5
million, $15.1 million and $0 for the years ended September 30, 2000, 1999, and
1998, respectively.

The Company does not provide U. S. federal income taxes on the undistributed
earnings of its foreign subsidiaries since the company intends to reinvest
indefinitely its earnings in such subsidiaries. It is not practical to determine
the U. S. federal income tax liability, if any, that would be payable if such
earnings were not reinvested indefinitely.

As of September 30, 2000, the Company had net operating loss carryforwards for
federal and state income tax purposes of $101.5 million and $63.1 million,
respectively, which are available to offset future taxable income through 2020
and 2005, respectively. Additionally the Company had research and development
tax credit carryforwards for federal and state income tax purposes of $9.8
million and $3.3 million, respectively, which are available to offset future
income taxes, if any, through 2015.

NOTE 7 - SIGNIFICANT CUSTOMERS, CONCENTRATION OF CREDIT RISK AND SEGMENT

NOTE 8 - RETIREMENT SAVINGS PLAN

The Company has a qualified retirement plan under the provisions of Section
401(k) of the Internal Revenue Code covering substantially all employees.
Participants in this plan may defer up to the maximum annual amount allowable
under IRS regulations. The contributions are fully vested and nonforfeitable at
all times. The Company does not make matching contributions under the plan.

NOTE 9 - COMMITMENTS AND CONTINGENCIES

The Company has entered into several agreements to lease land, a building and
equipment (collectively, the "property"). All of these leases have initial terms
of three to five years and options to renew for an additional one to three
years. The Company has the option to purchase the property at the end of each
initial lease term, and at the end of each renewal period for the lessor's
original cost, which is not less than the fair market value at each option date.
If the Company elects not to purchase the property at the end of each of the
leases, the Company would guarantee a residual value to the lessors equal to 84%
to 86% of the lessors' cost of the property equal to $79.8 million. As of
September 30, 2000, the lessors had advanced a total of $93.1 million under
these leases, and held $75.6 million as cash collateral, which amount is
included in restricted long-term deposits. Certain of these leases require the
Company to meet specific financial and other covenants, including restrictions
on the payment of cash dividends to its shareholders. As of September 30, 2000
the Company was in compliance with all covenants.

The Company also leases facilities and certain machinery and equipment under
noncancelable operating leases that expire through 2006.

Approximate minimum rental commitments under all noncancelable operating leases
as of September 30, 2000, are as follows (in thousands):

Rent expense totaled $6.0 million, $4.9 million and $4.1 million, for the years
ended September 30, 2000, 1999 and 1998, respectively.

The Company is a party to various investigations, lawsuits and claims arising in
the normal course of business. In the opinion of management, the ultimate
disposition of these matters will not have a material adverse effect on the
Company's consolidated financial position, results of operations or liquidity.

NOTE 10 - SUBSEQUENT EVENT (unaudited)

On October 2, 2000, the Company acquired all of the equity interests of First
Pass, Inc., in exchange for approximately $22.7 million in cash, common stock
and assumed stock options. This transaction will be recorded using the purchase
method of accounting.

GLOSSARY

ASIC (Application Specific Integrated Circuit) A semiconductor circuit
specifically designed to suit a customer's particular requirements, as opposed
to a DRAM or microcontroller, which are general purpose parts.

ATM (Asynchronous Transfer Mode) - A high-bandwidth, low-delay packet switching
and multiplexing technique used to transfer voice, images and character-based
data. ATM allows both voice and data to be transported over a shared circuit.

CMOS (Complementary Metal-Oxide-Silicon) Leading silicon-based technology
employed in the fabrication of integrated circuits that feature low power
consumption. CMOS also allows more transistors to be integrated on a single
circuit.

FEC (Forward Error Correction Circuits)  A technique of error detection and
correction in which the transmitting host computer includes some number of
redundant bits in the payload (data field) of a block or frame of data.

Framer - A device, which terminates various protocol and data rate streams to
provide client level information and connectivity to supporting layers.

Gigabit Ethernet - A local area network used for connecting computers, printers,
workstations, terminals, servers, etc. within the same building or campus.
Gigabit Ethernet operates over coaxial and fiber optic cable at speeds of 1.25
Gbps.

H-GaAs - A proprietary Gallium-Arsenide (GaAs) semiconductor technology
developed by Vitesse for large scale, high-speed, digital communication
applications.

InP HBT (Indium Phosphide Heterojunction Bipolar Transistor) - A process
technology based on the compound InP. Facilitates very powerful and cost-
effective solutions for implementing higher speeds.

IP (Internet Protocol) - A Layer 3 (network layer) protocol that contains
addressing information that allows packets to be routed.

LAN (Local Area Network) - A Short distance data communications network used to
link together computers and peripheral devices (such as printers) under some
form of standard control.

Network Processor - A class of processors architectured and optimized for
manipulating packetized data typical in communication protocols.

OC 192/OC 768 (Optical Carrier) - SONET channel of 10 billion bits per second
(10 Gbps) and 40 billion bits per second (40 Gbps), respectively.

Opto-electronic - The range of materials and devices associated with fiber optic
and infrared transmission systems.

Physical Layer - The OSI model defines Layer 1 as the physical layer and
includes all electrical and mechanical aspects relating to the connection of a
device to a transmission medium.

Pointer Processor - Pointer processors accommodate frequency differences by
adjusting the starting position of the payload within the frame. A pointer keeps
track of the starting position of the payload.

SAN (Storage Area Network) - A short-distance data communications network used
to link elements within a storage environment.

SiGe (Silicon Germanium) - A process technology that employs a Germanium-doped
silicon substrate upon which to fabricate circuits. This enables much higher
data rates than are possible with traditional silicon processes.

SONET (Synchronous Optical Network) A communications transmission technology,
carried on fiber optic networks, that greatly increases the efficiency and
reliability of local exchange and long-distance networks.

Switch Fabric - A device used to switch data among multiple ports in a
communications system. A switch fabric generally has a "crossbar" or "fabric"
architecture such that each of its multiple input data ports can be connected to
one or more of its output data ports simultaneously.

Telecommunications - The transmission, reception and the switching of signals,
such as electrical or optical, by wire, fiber or electromagnetic means.

TimeStream(R) - The Vitesse TimeStream product family provides a superior
solution for terminating, grooming, and mapping data into and out of SONET/SDH
interfaces. The products are designed to eliminate multiple devices by
integrating standard SONET/SDH backplane interfaces, working and protection
ports, and anticipating next generation system design requirements.

WAN (Wide Area Network) - A network that encompasses interconnectivity between
