                            CERTIFICATE OF AMENDMENT
                                       OF
                          CERTIFICATE OF INCORPORATION
                                       OF
                               EMULEX CORPORATION

         Emulex Corporation, a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware (the
"Corporation"), does hereby certify as follows:

         FIRST: That at a meeting of the Board of Directors of the Corporation,
resolutions were duly adopted setting forth a proposed amendment of the
Certificate of Incorporation, as amended, of the Corporation, declaring said
amendment to be advisable and to be presented to the stockholders at the annual
meeting of stockholders of the Corporation for consideration thereof. The
resolution setting forth the proposed amendment is as follows:

         "RESOLVED, that, Article IV of the Corporation's Certificate of
         Incorporation, as previously amended, be further amended, without
         effect upon any stock designation heretofore filed, to read as follows:

                                   ARTICLE IV
                            Authorized Capital Stock

                  The corporation is authorized to issue two classes of capital
         stock, designated Common Stock and Preferred Stock. The amount of total
         authorized capital stock of the corporation is 241,000,000 shares,
         divided into 240,000,000 shares of Common Stock, par value $0.10 per
         share, and 1,000,000 shares of Preferred Stock, par value $0.01 per
         share. Upon the effectiveness of this Amendment, each outstanding share
         of Common Stock, par value $0.10 per share, shall be split, converted
         and changed into two shares of Common Stock, par value $0.10 per share.
         The effective date of this Amendment shall be 11:59 p.m. (Eastern
         Standard Time) on November 30, 2000.

                  The shares of Preferred Stock may be issued from time to time
         in one or more series. The board of directors is hereby authorized to
         fix by resolution or resolutions the designations and the powers,
         preferences and relative, participating, optional or other special
         rights, and qualifications, limitations or restrictions of any series
         of shares of Preferred Stock, including without limitation the dividend
         rate, conversion rights, redemption price and liquidation preference,
         of any such series, and to fix the number of shares constituting such
         series, and to increase or decrease the number of shares of any such
         series (but not below the number of shares thereof then outstanding).
         In case the number of shares of any such series shall be so decreased,
         the shares constituting such decrease shall resume the status which
         they had prior to the adoption of the resolution or resolutions
         originally fixing the number of shares of such series."

<PAGE>   2

         SECOND: That thereafter, pursuant to resolutions of the Board of
Directors, the proposed amendment was presented to the stockholders at the
annual meeting of stockholders of the Corporation held on November 16, 2000,
upon notice in accordance with Section 222 of the General Corporation Law of the
State of Delaware, at which meeting the necessary number of shares as required
by statute were voted in favor of the amendment.

         THIRD: That said amendment was duly adopted in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware.

         IN WITNESS WHEREOF, the Corporation has caused this certificate to be
signed by Paul F. Folino, its President and Chief Executive Officer, and Michael
J. Rockenbach, its Vice President, Chief Financial Officer, Secretary and
Treasurer, as of this 16th day of November, 2000.

                                                                   EXHIBIT 10.32

                       COMMUNICATIONS & POWER INDUSTRIES
                             2000 STOCK OPTION PLAN

        1. Background; Purpose. Communications & Power Industries Holding
Corporation, a Delaware corporation (the "Company"), hereby adopts the
Communications & Power Industries 2000 Stock Option Plan (the "Plan"). The
purpose of the Plan is to provide an incentive for key employees, consultants,
advisors, and non-affiliate directors of the Company and its current and future
subsidiaries ("Subsidiaries") (a) to remain in the service of the Company and
its Subsidiaries, (b) to enhance the long-term performance of the Company and
its Subsidiaries, and (c) to acquire a proprietary interest in the Company and
its Subsidiaries.

        The Plan will provide a means whereby key employees, consultants,
advisors, and non-affiliate directors of the Company and its Subsidiaries may
purchase shares of Common Stock, par value $.01 per share, of the Company
("Common Stock") pursuant to "non-incentive" or "non-qualified" Stock Options
(as hereinafter defined). The Company intends that awards of Stock Options, and
the issuance of Common Stock upon exercise of Stock Options hereunder, shall
constitute the offer and sale of securities pursuant to a compensatory benefit
plan within the meaning of Rule 701 promulgated under the Securities Act of
1933, as amended (the "Securities Act"). The Stock Options granted pursuant to
this Plan shall not be "incentive stock option" within the meaning of Section
422 of the Internal Revenue Code, as amended

        2. Administration. The Plan shall be administered by the Board of
Directors of the Company (the "Board") or, in the discretion of the Board, a
Committee (in either case, the "Committee"), consisting of two or more directors
of the Company to whom administration of the Plan has been duly delegated.
Except as otherwise provided in the Company's Bylaws, any action of the
Committee with respect to administration of the Plan shall be taken by a
majority vote at a meeting at which a quorum is duly constituted or by unanimous
written consent of the Committee's members. The Committee may designate the
Secretary of the Company or other Company employees to assist the Committee in
the administration of the Plan, and may grant authority to such persons to
execute agreements or other documents evidencing Options awarded under this Plan
or other documents entered into under this Plan on behalf of the Committee or
the Company.

        Subject to the provisions of the Plan, the Committee shall have full,
unconditional, sole and final discretion and authority (i) to construe and
interpret the Plan and the Stock Option Agreements (as hereinafter defined),
(ii) to define the terms used herein, (iii) to prescribe, amend and rescind
rules and regulations relating to the Plan, (iv) to make awards of options to
purchase Common Stock ("Stock Options") hereunder, (v) to determine the
individuals to whom and the time or times at which awards of Stock Options shall
be made, the number of shares of Common Stock to be subject to such awards, the
vesting of such Stock Options, the time or times when vested Stock Options
become exercisable and the other terms of such Stock Options, (vi) to determine
the circumstances under which vesting or exercisability of any Stock Option may
be accelerated, (vii) to determine the exercise price (which shall not be less
than 85% of the fair market value per share of Common Stock on the date of the
award as determined by the Committee and, in the case of any person who owns
stock possessing more than 10% of the total combined voting power of all classes
of stock of the Company, shall not be less than 110% of the

<PAGE>   2

fair market value per share), and the duration of each Stock Option (which shall
not be more than ten years), (viii) to approve and determine the duration of
leaves of absence which may be granted to "Participants" (as hereinafter
defined) without constituting a termination of their employment or continuous
service for the purposes of the Plan or the relevant Stock Option Agreement,
(ix) to amend the terms of any outstanding Stock Option, with consent of the
holder (or as otherwise provided in this Plan), and (x) to make all other
determinations necessary or advisable for the administration of the Plan. All
determinations and interpretations made by the Committee shall be binding and
conclusive on all Participants in the Plan and their legal representatives and
beneficiaries.

        3. Shares Subject to the Plan. The shares to be sold upon the exercise
of Stock Options awarded under this Plan shall consist of the Company's
authorized but unissued Common Stock. Subject to adjustment as provided in
Section 6 hereof, the aggregate number of shares of Common Stock which may be
sold upon the exercise of Stock Options awarded to Participants pursuant to
Section 5 below shall not exceed 250,000 of such shares (the "Option Shares").
Option Shares subject to Stock Options that lapse or terminate without exercise
shall be available to be subject to newly issued Stock Options under the Plan. A
holder of Option Shares upon the exercise of his or her Stock Options shall be
entitled to all rights (including voting and dividend rights) of a holder of
Common Stock of the Company.

        4. Eligibility and Participation. All key employees, consultants,
advisors and non-affiliate directors of the Company and its Subsidiaries shall
be eligible for selection to participate in the Plan (each, a "Participant").

        5. Awards. A Participant may receive one or more awards hereunder, from
time to time, as determined by the Committee. Awards shall be in the form of
Stock Options. All awards of Stock Options shall be pursuant to, and shall be
subject to the terms and restrictions provided in, a Stock Option Agreement (a
"Stock Option Agreement") in a form determined by the Committee. Stock Options
shall not be transferable by a Participant either voluntarily or by operation of
law, other than by will or by the laws of descent and distribution, and shall be
exercisable during the Participant's lifetime only by the Participant. Subject
to the terms of the Plan, the Committee shall determine the exact terms and
restrictions included in each Stock Option Agreement with respect to each award
to a Participant.

        6. Adjustments. If the outstanding shares of the Common Stock of the
Company are increased, decreased, changed into or exchanged for a different
number of kind of shares or securities of the Company through:

                (i) a distribution or payment of a dividend on the Common Stock
        in shares of Common Stock;

                (ii) subdivision, recapitalization, reorganization or
        reclassification, in a stock split or similar transaction, of the
        outstanding shares of Common Stock into a greater number of shares;

                                      -2-
<PAGE>   3

                (iii) combination, recapitalization, reorganization or
        reclassification of, in a reverse stock split or similar transaction,
        the outstanding shares of Common Stock into a smaller number of shares;
        or

                (iv) issuance of any shares of capital stock by
        recapitalization, reorganization or reclassification of the Common Stock

then an appropriate and proportionate adjustment shall be made in the maximum
number and kind of shares which may be subject to Stock Options under this Plan
and to the number and kind of shares which are subject to outstanding Stock
Options.

        Adjustments under this Section 6 shall be made by the Committee, whose
determination as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

        7. Dissolution or Liquidation. In the event of the proposed dissolution
or liquidation of the Company, to the extent that a Stock Option had not been
previously exercised, it will terminate immediately prior to the consummation of
such proposed dissolution or liquidation. In such instance, the Committee may,
in the exercise of its sole discretion, declare that any Stock Option will
terminate as of a date fixed by the Committee and give each Participant the
right to exercise his or her Stock Option as to all or any part of the Option
Shares, including Option Shares as to which the Stock Option would not otherwise
be exercisable.

        8. Corporate Transaction. Upon the happening of a merger, reorganization
or sale of substantially all of the assets of the Company, the Committee, may,
in its discretion, do one or more of the following: (i) shorten the period
during which Stock Options are exercisable (provided they remain exercisable for
at least 30 days after the date notice of such shortening is given to the
Participants); (ii) accelerate any vesting schedule to which an Stock Option is
subject; (iii) arrange to have the surviving or successor entity assume the
Stock Options or grant replacement Stock Options with appropriate adjustments in
the exercise prices and adjustments in the number and kind of securities
issuable upon exercise or adjustments so that the Stock Options or their
replacements represent the right to purchase the shares of stock, securities or
other property (including cash) as may be issuable or payable as a result of
such transaction with respect to or in exchange for the number of Option Shares
purchasable and receivable upon exercise of the Stock Options had such exercise
occurred in full prior to such transaction; or (iv) cancel Stock Options upon
payment to the Participants in cash, with respect to each Stock Option to the
extent then exercisable (including any Stock Options as to which the exercise
has been accelerated as contemplated in clause (ii) above), of any amount that
is the equivalent of the excess of the fair market value of the Common Stock (at
the effective time of the merger, reorganization, sale or other event) over the
exercise price of the Stock Option. The Committee may also provide for one or
more of the foregoing alternatives in any particular Stock Option Agreement.

        9. Withholding Tax. The Company shall have the right to take whatever
steps the Committee deems necessary or appropriate to comply with all applicable
federal, state, local, and employment tax withholding requirements, and the
Company's obligations to deliver shares upon the exercise of Stock Options under
this Plan shall be conditioned upon compliance with all such

                                      -3-
<PAGE>   4

withholding tax requirements. Without limiting the generality of the foregoing,
upon the exercise of a Stock Option, the Company shall have the right to
withhold taxes from any other compensation or other amounts which it may owe to
the employee or to require such employee to pay to the Company the amount of any
taxes which the Company may be required to withhold with respect to such
exercise. Without limiting the generality of the foregoing, the Committee in its
discretion may, subject to compliance with applicable law and the Company's
contractual obligations, including without limitation, obligations under any
debt agreements to which the Company is a party, authorize a Participant to
satisfy all or part of any withholding tax liability by (A) having the Company
deduct from the shares which would otherwise be issued on the exercise of a
Stock Option that number of shares having a fair market value as of the date the
withholding tax liability arises equal to or less than the amount of the
withholding tax liability, or (B) by delivering to the Company previously-owned
and unencumbered shares of the Common Stock of the Company having a fair market
value as of the date the withholding tax liability arises equal to or less than
the amount of the withholding tax liability.

        10. Amendment and Termination of Plan. The Board may at any time suspend
or terminate the Plan. The Board may also at any time amend or revise the terms
of the Plan, provided that no such amendment or revision shall, unless
appropriate stockholder approval of such amendment or revision is obtained,
increase the maximum number of Option Shares, except as permitted under the
provisions of Section 6, or permit the granting of Stock Options to anyone other
than as provided in Section 4, or otherwise materially increase the benefits
accruing to Participants under the Plan.

        Notwithstanding the foregoing, no amendment, suspension or termination
of the Plan that would materially adversely affect any rights or obligations of
any Participant under any Stock Option Agreement shall be effective as to such
Participant unless there shall have been specific action of the Committee and
written consent of the Participant; provided, however, that the Board or the
Committee may unilaterally amend this Plan or any Stock Option Agreement,
without the consent of the Participant, if such amendment is necessary or
desirable to comply with the Securities Act, state blue sky laws, or applicable
requirements of any principal securities exchange or market on which shares of
the same class of securities are listed or traded.

        11. No Employment Rights. The selection of any person to receive an
award under the Plan shall not give such person any right to be retained in the
employment of, or to continue to render services to, the Company or any of its
Subsidiaries or any of their affiliates and the right and the power of the
Company or its Subsidiaries to discharge or terminate its relationship with any
such person shall not be affected by such award. No person shall have any right
or claim whatever, directly, indirectly or by implication, to receive an award,
nor any expectancy thereof, unless and until an award in fact shall have been
made to such person by the Committee as provided herein. The award to any person
hereunder at any time shall not create any right or implication that any other
or further award may or shall be made at another time. Each award hereunder
shall be separate and distinct from every other award and shall not be construed
as a part of any continuing series of awards or compensation.

        12. Compliance with Other Laws and Regulations. This Plan, the grant and
exercise of Stock Options thereunder, and the obligation of the Company to sell,
issue or deliver shares of Common Stock, shall be subject to all applicable
federal, state and foreign laws, rules and

                                      -4-
<PAGE>   5

regulations and to such approvals by any governmental or regulatory agency as
may be required. The Company shall not be required to register in a
Participant's name or deliver any shares of Common Stock prior to the completion
of any registration or qualification of such shares of Common Stock under any
federal, state or foreign law or any ruling or regulation of any government body
which the Committee shall determine to be necessary or advisable.

        Unless the Stock Options and the shares of Common Stock covered by this
Plan have been registered under the Securities Act or the Company has determined
that such registration is unnecessary, each person receiving a Stock Options
and/or Option Shares may be required by the Company to give a representation in
writing that such person is acquiring such shares for his or her own account for
investment and not with a view to, or for sale in connection with, the
distribution of any part thereof.

        13. Plan Not Exclusive. The Plan is not exclusive. The Company may have
other plans, programs and arrangements for compensation or the issuance of
shares of capital stock or options relating thereto. The Plan does not require
that Participants hereunder be precluded from participation in such other plans,
programs and arrangements.

        14. Effective Date and Term. This Plan shall be effective when it has
been adopted by the Board, provided that it is approved by the Holders of the
outstanding voting stock of the Company within 12 months thereafter. The term of
this Plan shall commence on the date of its adoption by the Board and shall
expire on the tenth (10th) anniversary of such date, unless earlier terminated.

Adopted by the Board of Directors of the Company on March 9, 2000.

Approved by the Stockholders of the Company on March 9, 2000.
