                                PROXY STATEMENT

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

                         ANNUAL MEETING OF STOCKHOLDERS
                                January 29, 2002

   This Proxy Statement is furnished in connection with the solicitation by the
Board of Directors (the "Board") of Vitesse Semiconductor Corporation
("Vitesse" or the "Company") of proxies to be voted at the Annual Meeting of
Stockholders to be held on Tuesday, January 29, 2002, at 10:30 a.m., and at any
adjournments that may take place.

   The Annual Meeting will be held at the Renaissance Hotel located at 30100
Agoura Road, Agoura Hills, California 91301. Vitesse anticipates sending the
proxy materials to stockholders on or about December 19, 2001.

   The following is important information in a question-and-answer format
regarding the Annual Meeting and this Proxy Statement.

Q: What may I vote on?

A: (1) The election of six nominees to serve on our Board of Directors.

   (2) The amendment of our 1991 Employee Stock Purchase Plan to reserve an
       additional 5,500,000 shares of Common Stock for issuance thereunder.

   (3) The approval of the appointment of our independent auditors for fiscal
       2002.

   (4) Any other business properly presented at the meeting.

Q: How does the Board recommend I vote on the proposals?

A: The Board recommends a vote FOR each of the director nominees, FOR the
   amendment of the 1991 Employee Stock Purchase Plan, and FOR the appointment
   of KPMG LLP as independent auditors for fiscal 2002.

Q: Who is entitled to vote?

A: Stockholders as of the close of business on December 4, 2001 (the "Record
   Date") are entitled to vote at the Annual Meeting. Each stockholder is
   entitled to one vote for each share of common stock held on the Record Date.
   As of the Record Date, 199,936,864 shares of the Company's common stock were
   issued and outstanding.

Q: How do I vote?

A: There are three ways you can vote:

  (1) Sign and date each proxy card you receive and return it in the prepaid
      envelope.

  (2) Vote through the Internet or telephone voting system more fully
      described on your proxy card.

  (3) Vote in person at the Annual Meeting. If your shares are held of record
      by a broker, bank or other nominee and you wish to attend the Annual
      Meeting, you must notify your broker, bank or other nominee and obtain
      the proper documentation to vote your shares at the Annual Meeting.

                                       1


Q: How can I change my vote or revoke my proxy?

A: You have the right to revoke your proxy and change your vote at any time
   before the meeting by notifying the Company's Secretary, or returning a
   later-dated proxy card, or by internet or telephone as more fully described
   on your proxy card. You may also revoke your proxy and change your vote by
   voting in person at the meeting.

Q: What does it mean if I get more than one proxy card?

A: It means you hold shares registered in more than one account. Sign and
   return all proxies to ensure that all your shares are voted.

Q: Who will count the vote?

A: Representatives of EquiServe, the Company's transfer agent, will count the
   votes and act as the Inspector of Election. The Company believes that the
   procedures to be used by the Inspector to count the votes are consistent
   with Delaware law concerning voting of shares and determination of a quorum.

Q: What is a "quorum"?

A: A "quorum" is a majority of the outstanding shares. They may be present at
   the meeting or represented by proxy. There must be a quorum for the meeting
   to be held and action to be validly taken. If you submit a properly executed
   proxy card, even if you abstain from voting, then you will be considered
   part of the quorum. Abstentions are not counted in the tally of votes FOR or
   AGAINST a proposal. A withheld vote is the same as an abstention. If a
   broker indicates on a proxy that it does not have discretionary authority as
   to certain shares to vote on a particular matter (broker non-votes), those
   shares will not be counted as present with respect to that matter for
   purposes of establishing a quorum.

Q: Who can attend the Annual Meeting?

A: All stockholders as of the Record Date can attend. If your shares are held
   of record by a broker, bank or other nominee and you wish to attend the
   Annual Meeting, you must notify your broker, bank or other nominee and
   obtain the proper documentation to vote your shares at the Annual Meeting.

Q: How will voting on any other business be conducted?

A: We do not know of any business to be considered at the 2002 Annual Meeting
   other than the proposals described in this proxy statement. However, because
   the Company did not receive notice of any other proposals to be brought
   before the meeting by November 8, 2001 (45 days prior to the month and day
   of last year when proxy materials for the 2001 Annual Meeting were mailed to
   stockholders), if any other business is properly presented at the Annual
   Meeting, your signed proxy card gives authority to Pierre R. Lamond,
   Vitesse's Chairman, and Louis R. Tomasetta, Vitesse's President and Chief
   Executive Officer, to vote on such matters at their discretion.

Q: Who are the largest principal stockholders?

A: Fidelity Management and Research Corporation owned 19,780,244 shares, or
   9.9%, as of September 30, 2001, according to information provided by
   Fidelity Management and Research Corporation.

Q: How and when may I submit proposals for the 2003 Annual Meeting?

A: To have your proposal included in the Company's Proxy Statement for the 2003
   Annual Meeting, you must submit your proposal in writing by August 21, 2002,
   to the Company's Secretary, c/o Vitesse Semiconductor Corporation, 741 Calle
   Plano, Camarillo, California 93012.

                                       2


   If you submit a proposal for the 2003 Annual Meeting after November 4, 2002,
   the proxy for the 2003 Annual Meeting may confer upon management
   discretionary authority to vote on your proposal.

   You should also be aware of certain other requirements you must meet to have
   your proposal included in the Company's Proxy Statement for the 2003 Annual
   Meeting that are explained in Rule 14a-8 promulgated by the Securities and
   Exchange Commission under the Securities Exchange Act of 1934.

Q: How much did this proxy solicitation cost?

A: Georgeson Shareholder Communications, Inc. was hired to assist in the
   distribution of proxy materials and solicitation of votes for $6,000, plus
   certain out-of-pocket expenses. We also reimburse brokerage houses and
   persons representing beneficial owners of shares for their reasonable out-
   of-pocket expenses in forwarding solicitation materials to such beneficial
   owners. Certain of the Company's directors, officers or employees may also
   solicit proxies in person or by telephone, but they will not receive any
   additional compensation for doing so.

                                       3


                           PROPOSALS YOU MAY VOTE ON

Proposal 1: Election of Directors.

   The Company has nominated six (6) candidates for election to the Board this
year. Detailed information on each of the Company's nominees is provided on
page 7. All directors are elected annually and serve a one-year term until the
next Annual Meeting. If any director is unable to stand for re-election, the
Board may reduce the size of the Board, designate a substitute or leave a
vacancy unfilled. If a substitute is designated, proxies voting on the original
director candidate will be cast for the substituted candidate. We expect that
each nominee listed on page 7 will be able and will not decline to serve as a
director.

Vote Required; Recommendation of the Board of Directors

   With respect to the election of directors, the six candidates receiving the
highest number of FOR votes shall be elected to the Company's Board of
Directors. An abstention will have the same effect as a vote withheld for the
election of directors, and, pursuant to Delaware law, a broker non-vote will
not be treated as voting in person or by proxy on the proposal.

  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" PROPOSAL 1.

Proposal 2: Approval of Amendment to the Company's Employee Stock Purchase Plan

   The Vitesse Semiconductor Corporation 1991 Employee Stock Purchase Plan (the
"Purchase Plan") was adopted by the Board of Directors and approved by the
shareholders in August 1991 and has been amended from time to time. A total of
7,500,000 shares of Common Stock has been reserved for issuance under the
Purchase Plan. Of these reserved shares, 998,030 shares remained for future
grant under the Purchase Plan as of November 30, 2001. The Board of Directors
has adopted an amendment to the Purchase Plan (the "Purchase Plan Amendment"),
subject to approval by the shareholders, to increase the number of shares
reserved for issuance under the Purchase Plan by an additional 5,500,000 shares
to an aggregate total of 13,000,000 shares. The Board further amended the
Purchase Plan to change the length of the offering periods from six months to
twenty-four months. The shareholders are being asked to approve the Purchase
Plan Amendment to increase the number of shares available under the Purchase
Plan.

   The following is a summary of the material provisions of the Purchase Plan,
as amended and restated, a copy of which may be obtained from the Company or
its publicly filed documents. The Purchase Plan, which qualifies under Section
423 of the Internal Revenue Code, provides for eligible employees to purchase
shares of the Company's Common Stock during offering periods of overlapping
twenty-four months that commence on February 1 and August 1 of each year and
end twenty-four months later on January 31 and July 31, respectively, before
the next period commences. Each offering period will be comprised of four
successive six-month purchase periods. Deductions will be made from a
participating employee's salary during each purchase period, and if the
employee has not withdrawn by the last day of the purchase period, stock will
be purchased for the account of the employee at the end of the purchase period
at the price as set forth below.

   Employees are eligible to participate after one month of employment if they
are regularly employed by the Company for at least 20 hours per week and more
than five months per calendar year. Employees who would immediately after the
grant own 5% or more of the total combined voting power or value of the stock
of the Company or any subsidiary are not eligible to participate. As of
November 30, 2001, approximately 1,100 of the Company's employees were eligible
to participate in the Purchase Plan. Because participation in the Purchase Plan
is voluntary, the Company cannot now determine the number of shares of Common
Stock to be purchased by any particular individual or group of individuals.

                                       4


   The Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions, which may not exceed 20% of an employee's base
compensation, including commissions, but excluding overtime and bonuses, at a
price equal to 85% of the fair market value of the Common Stock at the
beginning of the offering period or at the end of each purchase period,
whichever is lower. In the event that the fair market value at the beginning of
the offering period in which the participating employee is enrolled is higher
than at the beginning of any immediately subsequent offering period, the
participating employee shall automatically be re-enrolled for such subsequent
offering period, which results in participating employees having the
opportunity to buy stock at the lower values. Employees may end their
participation in the Purchase Plan at any time, and participation ends
automatically on termination of employment with the Company. In no event shall
any employee be permitted to purchase shares of Common Stock under the Purchase
Plan at a rate which exceeds $25,000 in fair market value (as measured at the
time the option is granted) of such Common Stock for each calendar year. In the
event of a proposed sale of all or substantially all the assets of the Company
or a merger of the Company with or into another corporation, the Purchase Plan
provides that each option under the Purchase Plan be assumed or an equivalent
option be substituted by the successor or purchaser corporation, unless the
Board decides to shorten the offering period or purchase period.

   Unless terminated sooner, the Purchase Plan will terminate 20 years from its
effective date. The Board has authority to amend or terminate the Purchase
Plan, provided that no such action may adversely affect the rights of any
participant.

Vote Required; Recommendation of the Board of Directors

   Approval of the Purchase Plan Amendment requires the affirmative vote of a
majority of the shares represented by person or by proxy and voting at the
Annual Meeting. Abstentions and broker non-votes are not counted as affirmative
votes with respect to approval of proposals such as the Purchase Plan
Amendment.

   The Board of Directors believes that it is in the best interests of the
Company and its shareholders to be able to continue to offer its present and
prospective employees the option to participate in the Purchase Plan in order
to advance the interests of the Company shareholders. Absent the approval of
this Proposal Two, it is expected that the Purchase Plan would terminate in
August 2002 as a result of an absence of shares available for issuance under
the Purchase Plan.

  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" PROPOSAL 2.

Proposal 3: Approval of the Appointment of KPMG LLP as Independent Auditors

   The Audit Committee has recommended, and the Board has approved, the
appointment of KPMG LLP ("KPMG") as our independent auditors for fiscal 2002
subject to your approval. KPMG has served as our independent auditors since
1991. Representatives of KPMG will attend the Annual Meeting to answer
appropriate questions. They also may make a statement.

   Audit services provided by KPMG during fiscal 2001 included an audit of the
Company's consolidated financial statements, a review of the Company's Annual
Report and certain other filings with the Securities and Exchange Commission
("SEC") and certain other governmental agencies. In addition, KPMG provided
various non-audit services to the Company during 2001.

Audit Fees

   The aggregate fees billed for professional services rendered by KPMG LLP for
the audit of our annual financial statements for the year ended September 30,
2001, and the reviews of the condensed financial statements included in our
quarterly reports on Forms 10-Q for the year ended September 30, 2001, were
$241,000.

                                       5


Financial Information Systems Design and Implementation Fees

   The aggregate fees billed for information technology services rendered by
KPMG LLP during the year ended September 30, 2001, were $0.

All Other Fees

   The aggregate fees billed for all other services, exclusive of the fees
disclosed above relating to financial statement audit services and financial
information systems design and implementation, rendered by KPMG LLP during the
year ended September 30, 2001, were $1,500,000. These other services consisted
of the following:


                                                                  
   - Statutory and Employee Benefit Audits.......................... $   16,000
   - Tax Services................................................... $1,333,000
   - Due Diligence.................................................. $   85,000
   - SEC Filings.................................................... $   66,000


   The Audit Committee has determined that the provision of these other
services is compatible with maintaining the independence of KPMG LLP.

Vote Required; Recommendation of the Board of Directors

   The Board of Directors has conditioned its appointment of the Company's
independent auditors upon the receipt of the affirmative vote of a majority of
the shares represented, in person or by proxy, and voting at the Annual
Meeting, which shares voting affirmatively also constitute at least a majority
of the required quorum. In the event that the stockholders do not approve the
selection of KPMG, the appointment of the independent auditors will be
reconsidered by the Board of Directors.

  THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE "FOR" PROPOSAL 3.

                                       6

                         BOARD MEETINGS AND COMMITTEES

   The Company's Board usually meets five times a year in regularly scheduled
meetings, but will meet more often if necessary. The Board held eight meetings
during fiscal 2001 and all of the directors attended at least 75% of the Board
meetings of which they were members.

   The full Board considers all major decisions of the Company. However, the
Board has established the following two standing committees, each of which is
chaired by an outside director:

  . Compensation Committee

   The Compensation Committee reviews and approves officers' salaries and
   employee compensation programs. During fiscal 2001, the Committee, which
   currently consists of Vincent Chan, Alex Daly and Pierre R. Lamond, met
   five times during fiscal 2001 and all members attended at least 75% of
   the meetings.

  . The Audit Committee

   The Audit Committee reviews and evaluates the Company's accounting
   principles and its system of internal accounting controls. It also
   recommends the appointment of the Company's independent auditors and
   approves the services performed by the auditors. The Committee, which
   currently consists of James A. Cole, Pierre R. Lamond and John C. Lewis,
   met four times during fiscal 2001 and all members attended at least 75%
   of the meetings.

   The Board currently has no nominating committee or committee performing a
similar function.

                             DIRECTOR COMPENSATION

   Non-employee directors receive $2,000 for each Board meeting attended in
person and $1,000 for each meeting attended by telephone. Directors are also
reimbursed for customary and usual travel expenses.

   All non-employee directors participate in the 1991 Directors' Stock Option
Plan (the "Directors' Plan"). Under the Directors' Plan, upon first becoming a
director, each non-employee director receives non-statutory options to purchase
40,000 shares (except for the Chairman, who receives options to purchase 60,000
shares). Additionally, every year on January 1 each director receives options
to purchase 40,000 shares (except for the Chairman who receives options to
purchase 60,000 shares). The size of the foregoing option grants are adjusted
to reflect the effects of stock splits, stock dividends, stock combinations and
the like. These options are for a ten-year term and become available for
purchase in installments of two percent of the total number of shares granted
at the end of each month beginning January 31 after the date of grant. The
exercise price of the options must be at least 100% of the fair market value of
the common stock on the Nasdaq National Market on the date of grant of the
option. The options may be exercised only (1) while the individual is serving
as a director on the Board, (2) within six months after termination by death or
disability, or (3) within three months after the individual's term as director

   During fiscal 2001, Mr. Lamond was granted an option to purchase 60,000
shares of common stock and Messrs. Chan, Cole, Daly and Lewis each were granted
an option to purchase 40,000 shares of common stock at an exercise price of
$55.3125.

   The Directors' Plan will expire on January 1, 2002. Under the 2001 Stock
Incentive Plan approved by our stockholders on January 23, 2001, each year
beginning in 2002, each non-employee director shall receive nonstatutory
options to purchase 40,000 shares (except for the Chairman, who shall receive
options to purchase 60,000 shares). These options are for a ten-year term and
become available for purchase in installments of two percent of the total
number of shares granted at the end of each month beginning January 31 after
the date of grant. The exercise price of the options must be at least 100% of
the fair market value of the common stock on the Nasdaq National Market on the
date of grant of the option. The options may be exercised only (1) while the
individual is serving as a director on the Board, (2) within six months after
termination by death or disability, or (3) within three months after the
individual's term as director ends.

   Employee directors receive no other compensation for serving on the Board.

                    REPORT OF THE COMPENSATION COMMITTEE OF
                             THE BOARD OF DIRECTORS

   The Compensation Committee of the Board of Directors consists of three non-
employee directors. The Committee reviews and approves salaries, bonuses and
other benefits payable to the Company's executive officers. It also administers
the Company's employee stock option and employee stock purchase plans.

Compensation Goals

   The Compensation Committee establishes compensation for executive officers
to align with business objectives and performance and to attract, retain and
reward executive officers who contribute to the long-term success of the
Company. The Company's compensation programs, including those for executive
officers, share these characteristics:

  . The Company pays competitively. The Company offers a compensation
    program, including competitive base salaries and, where appropriate,
    relocation benefits, to attract and retain the best people in the
    industry. To ensure that pay is competitive, the Company reviews the
    compensation practices of other leading companies in the industry.

  . The Company pays for relative sustained performance. Executive officers
    are rewarded based upon corporate, departmental, and individual
    performance. Corporate and departmental performance are evaluated by
    reviewing whether strategic and business plan goals are met. Individual
    performance is evaluated by measuring organizational progress against set
    objectives.

  . The Company strives for fairness to achieve a balance in compensation
    paid to the executives within the Company and in comparable companies. It
    believes that the contributions of each member of the executive staff are
    vital to the success of the Company.

  . The Company believes that employees should understand the performance
    evaluation and compensation programs. At the beginning of the performance
    cycle, key quarterly and annual objectives are set for each officer. The
    chief executive officer gives ongoing feedback on performance to each
    officer. At the end of the performance cycle, the Compensation Committee
    evaluates the accomplishments of the key objectives in making its
    decisions on merit increases and stock option grants.

Compensation Components

   The Company's compensation program, which consists of cash- and equity-based
compensation, allows the Company to attract and retain highly skilled officers,
provide useful products and services to customers, enhance stockholder value,
motivate technological innovation, and reward executive officers and other
employees. The components are:

Cash-Based Compensation:

  . Salary The Committee sets base salary for officers by reviewing the
    compensation levels for similar positions in comparable companies in the
    industry.

  . Bonus Under the Company's bonus plan, bonuses for eligible executive
    officers are generally paid as a percentage of their base salary and on
    the basis of the achievement of certain individual and corporate
    financial goals. The bonuses actually earned by each individual during
    any fiscal year are to be paid in successive years. In fiscal 2001, no
    bonuses were earned under the officers' bonus plan.

                                       13


Equity-Based Compensation:

   Stock options provide additional incentives to officers to work to maximize
stockholder value. The options become available for purchase over a defined
period to encourage officers to continue their employment with the Company. In
line with its compensation philosophy, the Company grants stock options to
employees at all levels of the organization based on each individual's
contribution to the Company.

Chief Executive Officer Compensation

   Louis R. Tomasetta has been President and Chief Executive Officer of the
Company since its incorporation in 1987. His total compensation consists of
base salary, bonus and employee stock options. In determining Mr. Tomasetta's
compensation, the Committee evaluates:

  . Corporate performance, principally revenue and operating profit goals.

  . His individual performance

  . Compensation paid to other executive officers of the Company

  . Compensation paid to chief executive officers of comparable companies

   For fiscal year 2001, Mr. Tomasetta's salary was $316,827. For his
performance in the prior year, he received non-statutory options to purchase
1,200,000 shares of common stock under the Company's 1991 Stock Option Plan at
an exercise price of $17.4375. These options are for a ten-year term and become
available to purchase in annual installments of 20% of the total number of
shares granted beginning on January 1, 2002. Mr. Tomasetta's equity ownership
in the Company includes 510,983 shares of common stock and stock options to
purchase an additional 3,450,312 shares. He shares significantly in the success
of the Company's business with the other stockholders.

Audit Committee Report

   In accordance with the written charter (attached as Appendix A hereto)
adopted by the Board of Directors, the Audit Committee of the Board (the
"Committee") reviews and evaluates the Company's accounting principles and its
system of internal accounting controls. It also recommends the appointment of
the Company's independent auditors and approves the services performed by the
auditors. The members of the Committee have been determined to be independent
pursuant to Rule 4200(a)(15) of the National Association of Securities Dealers
("NASD") listing standards.

                                       14


   The Committee has received from the independent auditors a formal written
statement describing all relationships between the auditors and the Company
that might bear on the auditors' independence consistent with Independence
Standards Board Standard No. 1, "Independence Discussions with Audit
Committees," and has discussed with the auditors any relationships that may
impact their objectivity and independence, and satisfied itself as to the
auditors' independence. The Committee also discussed with management, the
internal auditors and the independent auditors the quality and adequacy of the
Company's internal controls and the internal audit function's organization,
responsibilities, budget and staffing. The Committee also reviewed with both
the independent and the internal auditors their audit plans, audit scope, and
identification of audit risks.

   The Committee has discussed and reviewed with the independent auditors all
communications required by generally accepted accounting standards, including
those described in Statement on Auditing Standards No. 61, as amended,
"Communication with Audit Committees" and, with and without management present,
discussed and reviewed the results of the independent auditors' examination of
the financial statements. The Committee also discussed the results of the
internal audit examinations.

   The Committee has reviewed and discussed the audited financial statements of
the Company as of and for the fiscal year ended September 30, 2001, with
management and the independent auditors. Management has the responsibility for
the preparation of the Company's financial statements and the independent
auditors have the responsibility for the examination of those statements.

   Based on the above review and discussions with management and the
independent auditors, the Committee recommended to the Board of Directors that
the Company's audited financial statements be included in its Annual Report on
Form 10-K for the last fiscal year for filing with the Securities and Exchange
Commission. The Committee also recommended the reappointment, subject to
stockholder approval, of the independent auditors, and the Board concurred in
such recommendation.

   Submitted by the Audit Committee of the Company's Board of Directors:

            (iii) When a Participant reaches the end of an Offering Period but
     his or her participation is to continue, then such Participant shall
     automatically be re-enrolled for the Offering Period that commences
     immediately after the end of the prior Offering Period.

                                       3


     5. Participation
        -------------

        (a) An eligible Employee may become a Participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office at
least ten (10) business days prior to the applicable Enrollment Date, unless a
later time for filing the subscription agreement is set by the Board for all
eligible Employees with respect to a given Offering Period.

        (b) Once enrolled in the Plan, a Participant shall continue to
participate in the Plan until he or she ceases to be an eligible Employee,
withdraws from the Plan under paragraph 10(a) or reaches the end of the Purchase
Period in which his or her employee contributions were discontinued under
paragraph 6(d). A Participant who withdrew from the Plan under paragraph 10(a)
may again become a Participant, if he or she then is an eligible employee, by
following the procedure described in paragraph 5(a) above. A Participant whose
employee contributions were discontinued automatically under paragraph 6(d)
shall automatically resume participation at the beginning of the earliest
Purchase Period ending in the next calendar year, if he or she then is an
eligible employee.

     6. Payroll Deductions
        ------------------

        (a) At the time a Participant files his or her subscription agreement,
he or she shall elect to have payroll deductions made on each pay day during the
Offering Period in an amount not exceeding twenty percent (20%) of the
Compensation which he or she receives on each pay day during the Offering
Period, and the aggregate of such payroll deductions during the Offering Period
shall not exceed twenty percent (20%) of the Participant's Compensation during
said Offering Period.

        (b) All payroll deductions made for a Participant shall be credited to
his or her account under the Plan and will be withheld in whole percentages
only. A Participant may not make any additional payments into such account.

        (c) A Participant may discontinue his or her participation in the Plan
as provided in paragraph 10. A Participant's subscription agreement shall remain
in effect for successive Offering Periods unless terminated as provided in
paragraph 10.

        (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and paragraph 3(b) herein, a Participant's
payroll deductions may be decreased to 0% at such time during any Offering
Period which is scheduled to end during the current calendar year (the "Current
Offering Period") that the aggregate of all payroll deductions which were
previously used to purchase stock under the Plan in a prior Offering Period
which ended during that calendar year plus all payroll deductions accumulated
with respect to the Current Offering Period equal $21,250. Payroll deductions
shall recommence at the rate provided in such Participant's subscription
agreement at the beginning of the first Offering Period which is scheduled to
end in the following calendar year, unless terminated by the Participant as
provided in paragraph 10.

        (e) At the time the option is exercised, in whole or in part, or at the
time some or all of the Company's Common Stock issued under the Plan is disposed
of, the Participant must make adequate provision for the Company's federal,
state, or other tax withholding obligations, if any, which arise upon the
exercise of the Option or the disposition of the Common Stock.  At any time,

                                       4


the Company may, but will not be obligated to, withhold from the Participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefit attributable to sale or early disposition of
Common Stock by the Employee.

     7. Grant of Option and Purchase Price
        ----------------------------------

        (a) On the Enrollment Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Exercise Date during such Offering Period (at the applicable
Purchase Price) up to a number of shares of the Company's Common Stock
determined by dividing such Employee's payroll deductions accumulated prior to
such Exercise Date and retained in the Participant's account as of the Exercise
Date by the applicable Purchase Price; provided that in no event shall an
Employee be permitted to purchase during any Purchase Period more than a number
of shares determined by dividing $12,500 by the fair market value of a share of
the Company's Common Stock on the Enrollment Date, and provided further that
such purchase shall be subject to the limitations set forth in paragraphs 3(b)
and 12 hereof. To the extent that the payroll deductions on behalf of an
Employee exceed the aggregate Purchase Price, the payroll deductions credited to
such Participant's account during the Offering Period may be returned to the
Employee or credited to a following Purchase Period. Exercise of the option
shall occur as provided in paragraph 8, unless the Participant has withdrawn
pursuant to paragraph 10, and such option shall expire on the last day of the
Offering Period.

          (b) The Purchase Price for each share of Stock purchased at the close
of a Purchase Period shall be the lower of:

              (i)  85% of the Fair Market Value of such share on the last
          Trading Day in such Purchase Period; or

              (ii) 85% of the Fair Market Value of such share on the last
          Trading Day before the commencement of the applicable Offering Period
          (as determined under Section 4(c)).

     8. Exercise of Option   Unless a Participant withdraws from the Plan as
        ------------------
provided in paragraph 10 below, his or her option for the purchase of shares
will be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such Participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account.  No fractional shares will be purchased; any payroll deductions
accumulated in a Participant's account which are not sufficient to purchase a
full share shall be retained in the Participant's account for the subsequent
Offering Period, subject to earlier withdrawal by the Participant as provided in
paragraph 10.  Any other monies left over in a Participant's account after the
Exercise Date shall be returned to the Participant.  During a Participant's
lifetime, a Participant's option to purchase shares hereunder is exercisable
only by him or her.

     9. Delivery   As promptly as practicable after each Exercise Date on which
        --------
a purchase of shares occurs, the Company shall arrange the delivery to each
Participant, as appropriate, of a certificate representing the shares purchased
upon exercise of his or her option.

                                       5


     10. Withdrawal; Termination of Employment
         -------------------------------------

         (a) A Participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan.  All of the Participant's payroll deductions
credited to his or her account will be paid to such Participant promptly after
receipt of notice of withdrawal and such Participant's option for the Offering
Period will be automatically terminated, and no further payroll deductions for
the purchase of shares will be made during the Offering Period.  If a
Participant withdraws from an Offering Period, payroll deductions will not
resume at the beginning of the succeeding Offering Period unless the Participant
delivers to the Company a new subscription agreement.

         (b) Upon a Participant's ceasing to be an Employee for any reason or
upon termination of a Participant's employment relationship (as described in
paragraph 2(h)), the payroll deductions credited to such Participant's account
during the Offering Period but not yet used to exercise the option will be
returned to such Participant or, in the case of his or her death, to the person
or persons entitled thereto under paragraph 14, and such Participant's option
will be automatically terminated.

         (c) In the event an Employee fails to remain an Employee of the Company
for at least twenty (20) hours per week during an Offering Period in which the
Employee is a Participant, he or she will be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to his or her account will be
returned to such Participant and such Participant's option terminated.

         (d) A Participant's withdrawal from an Offering Period will not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the Participant
withdraws.

     11. Interest   No interest shall accrue on the payroll deductions of a
         --------
Participant in the Plan.

     12. Stock
         -----

         (a) The maximum number of shares of the Company's Common Stock which
shall be made available for sale under the Plan shall be 13,000,000 shares,
subject to adjustment upon changes in capitalization of the Company as provided
in paragraph 18. If on a given Exercise Date the number of shares with respect
to which options are to be exercised exceeds the number of shares then available
under the Plan, the Company shall make a pro rata allocation of the shares
remaining available for purchase in as uniform a manner as shall be practicable
and as it shall determine to be equitable.

         (b) The Participant will have no interest or voting right in shares
covered by his option until such option has been exercised.

         (c) Shares to be delivered to a Participant under the Plan will be
registered in the name of the Participant or in the name of the Participant and
his or her spouse.


                                       6


     13. Administration  The Plan shall be administered by the Board of the
         --------------
Company or a committee of members of the Board appointed by the Board.  The
Board or its committee shall have full and exclusive discretionary authority to
construe, interpret and apply the terms of the Plan, to determine eligibility
and to adjudicate all disputed claims filed under the Plan.  Every finding,
decision and determination made by the Board or its committee shall, to the full
extent permitted by law, be final and binding upon all parties.  Members of the
Board who are eligible Employees are permitted to participate in the Plan,
provided that:

         (a) Members of the Board who are eligible to participate in the Plan
may not vote on any matter affecting the administration of the Plan or the grant
of any option pursuant to the Plan.

         (b) If a Committee is established to administer the Plan, no member of
the Board who is eligible to participate in the Plan may be a member of the
Committee.

     14. Designation of Beneficiary
         --------------------------

         (a) A Participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the Participant's account under
the Plan in the event of such Participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such Participant of
such shares and cash. In addition, a Participant may file a written designation
of a beneficiary who is to receive any cash from the Participant's account under
the Plan in the event of such Participant's death prior to exercise of the
option.

         (b) Such designation of beneficiary may be changed by the Participant
at any time by written notice. In the event of the death of a Participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such Participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the Participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
Participant, or if no spouse, dependent or relative known to the Company, then
to such other person as the Company may designate.

     15. Transferability   Neither payroll deductions credited to a
         ---------------
Participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in paragraph 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with paragraph 10.

     16. Use of Funds   All payroll deductions received or held by the Company
         ------------
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     17. Reports   Individual accounts will be maintained for each Participant
         -------
in the Plan.  Statements of account will be given to participating Employees at
least annually, which statements will set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

                                       7


     18. Adjustments Upon Changes in Capitalization, Dissolution, Merger, Asset
         ----------------------------------------------------------------------
Sale or Change of Control
- -------------------------

         (a) Changes in Capitalization   Subject to any required action by the
             -------------------------
stockholders of the Company, the Reserves, as well as the price per share of
Common Stock covered by each option under the Plan which has not yet been
exercised, shall be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of shares of Common Stock
effected without receipt of consideration by the Company; provided, however,
that conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration."  Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive.  Except as expressly provided herein, no issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an option.

         (b) Dissolution or Liquidation    In the event of the proposed
             ---------------------------
dissolution or liquidation of the Company, the Offering Period will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

         (c) Merger or Asset Sale   In the event of a proposed sale of all or
             --------------------
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each option under the Plan shall be assumed or
an equivalent option shall be substituted by such successor corporation or a
parent or subsidiary of such successor corporation, unless the Board determines,
in the exercise of its sole discretion and in lieu of such progress by setting a
new Exercise Date (the "New Exercise Date").  If the Board shortens the Offering
Period then in progress in lieu of assumption or substitution in the event of a
merger or sale of assets, the Board shall notify each Participant in writing, at
least ten (10) days prior to the New Exercise Date, that the Exercise Date for
his option has been changed to the New Exercise Date and that his option will be
exercised automatically on the New Exercise Date, unless prior to such date he
has withdrawn from the Offering Period as provided in paragraph 10.  For
purposes of this paragraph, an option granted under the Plan shall be deemed to
be assumed if, following the sale of assets or merger, the option confers the
right to purchase, for each share of option stock subject to the option
immediately prior to the sale of assets or merger, the consideration (whether
stock, cash or other securities or property) received in the sale of assets or
merger by holders of Common Stock for each share of Common Stock held on the
effective date of the transaction (and if such holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of
the outstanding shares of Common Stock); provided, however, that if such
consideration received in the sale of assets or merger was not solely common
stock of the successor corporation or its parent (as defined in Section 424(e)
of the Code), the Board may, with the consent of the successor corporation and
the Participant, provide for the consideration to be received upon exercise of
the option to be solely common stock of the successor corporation or its parent
equal in fair market value to the per share consideration received by holders of
Common Stock and the sale of assets or merger.

                                       8


      19. Amendment or Termination
          ------------------------

          (a) The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in paragraph 18, no such
termination can affect options previously granted, provided that an Offering
Period may be terminated by the Board of Directors on any Exercise Date if the
Board determines that the termination of the Plan is in the best interests of
the Company and its stockholders. Except as provided in paragraph 18, no
amendment may make any change in any option theretofore granted which adversely
affects the rights of any Participant. To the extent necessary to comply with
Rule 16b-3 under the Securities Exchange Act of 1934, as amended, or under
Section 423 of the Code (or any successor rule or provision or any other
applicable law or regulation), the Company shall obtain stockholder approval in
such a manner and to such a degree as required.

         (b) Without stockholder consent and without regard to whether any
Participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a Participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each Participant properly correspond with amounts withheld from the
Participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

     20. Notices  All notices or other communications by a Participant to the
         -------
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     21. Conditions Upon Issuance of Shares   Shares shall not be issued with
         ----------------------------------
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

     As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

     22. Term of Plan   The Plan shall become effective upon the earlier to
         ------------
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of twenty
(20) years unless sooner terminated under paragraph 19.

                       1991 EMPLOYEE STOCK PURCHASE PLAN

                             Subscription Agreement

1. I,                             , hereby elect to participate in the Vitesse
      ----------------------------
   Semiconductor Corporation (the "Company") 1991 Employee Stock Purchase Plan
   (the "Purchase Plan") and subscribe to purchase shares of the Company's
   Common Stock in accordance with this Subscription Agreement and the Purchase
   Plan.

2. I hereby authorize payroll deductions from each paycheck in the amount of
           % of my Compensation on each payday (not to exceed 20%) during the
   --------
   Offering Period in accordance with the Purchase Plan (no fractional
   percentages are permitted).

3. I understand that said payroll deductions shall be accumulated for the
   purchase of shares of Common Stock at the applicable Purchase Price
   determined in accordance with the Purchase Plan.  I understand that if I do
   not withdraw from an Offering Period, any accumulated payroll deductions will
   be used to automatically exercise my option.

4. I understand that my participation is in all respects subject to the terms of
   the Purchase Plan.

5. I understand that under the Purchase Plan shares are issued in the name of
   the Participant or in the name of the Participant and his or her spouse.

6. I understand that if I dispose of any shares received by me pursuant to the
   Purchase Plan within two (2) years after the Enrollment Date (the first day
   of the Offering Period during which I purchased such shares), I will be
   treated for Federal income tax purposes as having received ordinary income in
   the year of sale equal to the difference between the purchase price of the
   shares and the fair market value of the shares on the date of exercise
   (purchase).  Any additional gain (or loss) (measured using the fair market
   value of the shares on the date of exercise (purchase)) is a capital gain (or
   loss).    I agree to notify the Company in writing within 30 days after the
   date of any such disposition and I will make adequate provision for Federal,
   State or other tax withholding obligations, if any, which arise upon the
   disposition of the Common Stock.

   If I dispose of such shares after the expiration of the two-year holding
   period, I understand that I will be treated for Federal income tax purposes
   as having received ordinary income equal to the lesser of (i) the excess of
   the fair market value of the shares at the time of disposition over the
   amount paid for the shares or (ii) the excess of the fair market value of the
   shares on the date of grant (enrollment) over the exercise (purchase) price
   (determined as if the option were exercised on the date of grant). Any
   additional gain (or loss) is capital gain (or loss). The applicable capital
   gain rate will depend on the actual length of my holding period.

7. I hereby agree to be bound by the terms of the Purchase Plan. The
   effectiveness of this Subscription Agreement is dependent upon my eligibility

   beneficiary(ies) to receive all payments and shares due me under the Purchase
