Exhibit 10.4

QLOGIC CORPORATION

CHANGE IN CONTROL SEVERANCE AGREEMENT

THIS CHANGE IN CONTROL SEVERANCE AGREEMENT (this “Agreement”) is made and
entered into as of [            , 20    ] by and between QLogic Corporation, a
Delaware corporation (the “Company”), and [                    ] (the
“Executive”).

RECITALS

A. The Board of Directors of the Company has approved the Company entering into
a severance agreement with the Executive.

B. The Executive is a key executive of the Company.

C. Should the possibility of a Change in Control of the Company arise, the Board
believes it is imperative that the Company and the Board be able to rely upon
the Executive to continue in his or her position, and that the Company should be
able to receive and rely upon the Executive’s advice, if requested, as to the
best interests of the Company and its stockholders without concern that the
Executive might be distracted by the personal uncertainties and risks created by
the possibility of a Change in Control.

D. Should the possibility of a Change in Control arise, in addition to his or
her regular duties, the Executive may be called upon to assist in the assessment
of such possible Change in Control, advise management and the Board as to
whether such Change in Control would be in the best interests of the Company and
its stockholders, and to take such other actions as the Board might determine to
be appropriate.

E. This Agreement provides the benefits the Executive will be entitled to
receive upon certain terminations of employment in connection with a Change in
Control from and after the Effective Date and supersedes and negates all
previous agreements with respect to such benefits.

NOW THEREFORE, to help assure the Company that it will have the continued
dedication of the Executive and the availability of his or her advice and
counsel notwithstanding the possibility, threat, or occurrence of a Change in
Control of the Company, and to induce the Executive to remain in the employ of
the Company in the face of these circumstances and for other good and valuable
consideration, the Company and the Executive agree as follows:

Article 1. Term

This Agreement shall be effective as of [            , 20    ] (the “Effective
Date”). This Agreement will continue in effect through [            , 20    ].
However, as of [            , 20    ] and each year thereafter, the term of this
Agreement shall be extended automatically for one (1) additional year (such that
on [            , 20    ] the term of this Agreement shall be extended through
[            , 20    ] and so on), unless the Committee delivers written notice
prior to such [                    ] to the Executive that this Agreement will
not be extended or further extended, as the case may be, and if such notice is
given this Agreement will terminate at the end of the term then in progress.

 

1

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

Notwithstanding the foregoing, in the event a Change in Control occurs during
the original or any extended term of this Agreement, this Agreement will remain
in effect for the longer of: (i) twenty-four (24) months beyond the month in
which such Change in Control occurred; or (ii) until all obligations of the
Company hereunder have been fulfilled, and until all benefits required hereunder
have been paid to the Executive. For purposes of clarity, subject to
Section 3.1, benefits shall be payable to the Executive under this Agreement
only with respect to a single Change in Control of the Company. Accordingly, no
Change in Control after the first Change in Control shall be considered for
purposes of this Agreement.

4

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

provided, however, that a transaction shall not constitute a Change in Control
unless it is a “change in the ownership or effective control” of the Company, or
a change “in the ownership of a substantial portion of the assets” of the
Company within the meaning of Section 409A of the Code. Notwithstanding the
foregoing, in no event shall a transaction or other event that occurred prior to
the Effective Date constitute a Change in Control.

 

  (i) “Code” means the United States Internal Revenue Code of 1986, as amended.

 

  (j) “Committee” means the Compensation Committee of the Board.

 

  (k) “Company” means QLogic Corporation, a Delaware corporation, or any
successor thereto as provided in Article 7.

 

  (l) “Disability” means disability as defined in the Company’s long-term
disability plan in which the Executive participates at the relevant time or, if
the Executive does not participate in a Company long-term disability plan at the

authorities, duties, and/or responsibilities (when such authorities, duties,
and/or responsibilities are viewed in the aggregate) from their level in effect
on the day immediately prior to the start of the Protected Period, other than an
insubstantial and inadvertent act that is remedied by the Company promptly after
receipt of notice thereof given by the Executive. The change in status of the
Company from a publicly-traded company to a company the securities of which are
not publicly-traded (including any related termination of the Company’s
reporting obligations under the Exchange Act) shall not, in and of itself,
constitute Good Reason or a material reduction in the nature or status of the
Executive’s authorities, duties, and/or responsibilities.

 

  (ii) A reduction by the Company in either the Executive’s Base Salary or the
Executive’s Annual Bonus opportunity as in effect immediately prior to the start

Executive’s level of coverage under all such programs must be at least as great
as is provided to other senior executives of the Company.

 

  (iv) The failure of the Company to obtain a satisfactory agreement from any

fifty (50) miles from his or her principal place of employment for the Company
at the start of the corresponding Protected Period.

 

  (vi) A repudiation or breach by the Company or any successor company of any of
the provisions of this Agreement.

The Executive’s right to terminate employment for Good Reason shall not be
affected by the Executive’s incapacity due to physical or mental illness. The
Executive’s continued employment shall not constitute a consent to, or a waiver
of rights with respect to, any circumstances constituting Good Reason herein;
provided, however, that if the Executive does not terminate employment and claim
Good Reason for such termination within ninety (90) days after the Executive has
knowledge of an event or circumstance that would constitute Good Reason, then
the Executive shall be deemed to have waived his or her right to claim Good
Reason as to that specific fact or circumstance (except that the event or
circumstance may be considered for purposes of determining whether any
subsequent, separate, event or circumstance constitutes Good Reason; for
example, and without limitation, a reduction in the Executive’s authorities that
is deemed waived by operation of this clause may be considered for purposes of
determining whether any subsequent reduction in the Executive’s authorities
(when taken into consideration with the first reduction) constitutes a “material
reduction” in the nature or status of the Executive’s authorities from their
level in effect on the day immediately prior to the start of the Protected
Period). In addition, any such event or circumstance shall not constitute “Good
Reason” unless both (x) the Executive provides written notice to the Company of
the event or circumstance claimed to constitute Good Reason within thirty
(30) days of the initial existence of such event or circumstance , and (y) the
Company fails to remedy such event or circumstance within thirty (30) days of
receiving such written notice thereof.

date of such Change in Control and ending on the date of such Change in Control.

 

  (r) “Qualifying Termination” has the meaning given to such term in
Section 3.2(a).

 

  (s) As used herein, a “Separation from Service” occurs when the Executive
dies, retires, or otherwise has a termination of employment with the Company
that constitutes a “separation from service” within the meaning of Treasury
Regulation Section 1.409A-1(h)(1), without regard to the optional alternative
definitions available thereunder.

 

  (t) “Severance Benefits” means the payments and/or benefits provided in
Section 3.3.

 

  (u) “Severance Date” means the date on which the Executive’s employment with
the Company and its subsidiaries terminates for any reason (whether or not as a
result of a Qualifying Termination).

 

  (v) “Subsidiary” means any corporation or other entity a majority of whose
outstanding voting stock or voting power is beneficially owned directly or
indirectly by the Company.

Article 3. Severance Benefits

3.1. Right to Severance Benefits. The Executive shall be entitled to receive
from the Company the Severance Benefits described in Section 3.3 if the
Executive has incurred a Qualifying Termination and satisfies the release
requirements set forth in Section 3.7.

The Executive shall not be entitled to receive Severance Benefits if his or her
employment terminates (regardless of the reason) before the Protected Period
corresponding to a Change in Control of the Company or more than twenty-four
(24) months after the date of a Change in Control of the Company.

3.2. Qualifying Termination.

 

  (a) Subject to Sections 3.2(c), 3.4, and 3.5, the occurrence of any one or
more of the following events within the Protected Period corresponding to a
Change in Control of the Company, or within twenty-four (24) calendar months
following the date of a Change in Control of the Company shall constitute a
“Qualifying Termination”:

 

  (i) An involuntary termination of the Executive’s employment by the Company
for reasons other than Cause; or

 

  (ii) A voluntary termination of employment by the Executive for Good Reason.

 

7

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

  (b) Notwithstanding anything else contained herein to the contrary, the
Executive’s termination of employment on account of reaching mandatory
retirement age, as such age may be defined from time to time in policies adopted
by the Company prior to the commencement of the Protected Period, and consistent
with applicable law, shall not be a Qualifying Termination.

 

  (c) Notwithstanding anything else contained herein to the contrary, the
Executive’s Severance Benefits under this Agreement shall be reduced by the
severance benefits (including, without limitation, any other change-in-control
severance benefits and any other severance benefits generally) that the
Executive may be entitled to under any other plan, program, agreement or other
arrangement with the Company (including, without limitation, any such benefits
provided for by an employment agreement). For purposes of the foregoing, any
cash severance benefits payable to the Executive under any other plan, program,
agreement or other arrangement with the Company shall offset the cash severance
benefits otherwise payable to the Executive under this Agreement on a
dollar-for-dollar basis. For purposes of the foregoing, non-cash severance
benefits to be provided to the Executive under any other plan, program,
agreement or other arrangement with the Company shall offset any corresponding
benefits otherwise to be provided to the Executive under this Agreement or, if
there are no corresponding benefits otherwise to be provided to the Executive
under this Agreement, the value of such benefits shall offset the cash severance
benefits otherwise payable to the Executive under this Agreement on a
dollar-for-dollar basis. If the amount of other benefits to be offset against
the cash severance benefits otherwise payable to the Executive under this
Agreement in accordance with the preceding two sentences exceeds the amount of
cash severance benefits otherwise payable to the Executive under this Agreement,
then the excess may be used to offset other non-cash severance benefits
otherwise to be provided to the Executive under this Agreement on a
dollar-for-dollar basis. For purposes of this paragraph, the Committee shall
reasonably determine the value of any non-cash benefits.

3.3. Description of Severance Benefits. In the event that the Executive becomes
entitled to receive Severance Benefits, as provided in Sections 3.1, 3.2 and
3.8, the Company shall pay and provide to the Executive (in addition to the
Accrued Obligations) the following:

 

  (a)

The Company will pay to the Executive an amount equal to one (1) times the sum
of (i) the Executive’s Base Salary and (ii) the Executive’s Annual Bonus. For
purposes of this Section 3.3(a), the Executive’s “Base Salary” shall be deemed
to be the Executive’s highest annualized rate of Base Salary in effect at any
time after the commencement of the Protected Period and on or before the
Executive’s Severance Date, and the Executive’s “Annual Bonus” shall be the
greater of (x) the Executive’s maximum Annual Bonus opportunity for the fiscal
year in which the Executive’s Severance Date occurs, and (y) the highest
aggregate bonus(es) paid by the Company to the Executive for any one of the
three (3) full fiscal years of the Company immediately preceding the Executive’s
Severance Date. Notwithstanding the foregoing provisions, if the Executive would
be entitled to a greater cash severance payment in the circumstances under the
terms of any employment agreement then in effect than the amount determined
under the first

 

8

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

  sentence of this Section 3.3(a), the Executive shall be entitled to such
greater cash severance payment only and no additional payment shall be made
under this Section 3.3(a).

 

  (b) The Company will pay or reimburse the Executive for his or her premiums
charged to continue medical coverage pursuant to the Consolidated Omnibus Budget
Reconciliation Act (“COBRA”), at the same or reasonably equivalent medical
coverage for the Executive (and, if applicable, the Executive’s eligible
dependents) as in effect immediately prior to the Severance Date, to the extent
that the Executive elects such continued coverage; provided that the Company’s
obligation to make any payment or reimbursement pursuant to this clause
(ii) shall cease upon the first to occur of (a) the first anniversary of the
Severance Date; (b) the Executive’s death; (c) the date the Executive becomes
eligible for coverage under the health plan of a future employer; or (d) the
date the Company or its affiliates ceases to offer any group medical coverage to
its active executive employees or the Company is otherwise under no obligation
to offer COBRA continuation coverage to the Executive. To the extent that the
payment of any COBRA premiums pursuant to this Section 3.3(b) is taxable to the
Executive, such payment shall be made on or before the last day of the
Executive’s taxable year following the taxable year in which the related expense
was incurred. The Executive’s right to payment of such premiums is not subject
to liquidation or exchange for another benefit and the amount of such benefits
that the Executive receives in one taxable year shall not affect the amount of
such benefits that the Executive receives in any other taxable year.

 

  (c) Notwithstanding any other provision herein or in any other document, any
stock option or other equity-based award granted by the Company to the
Executive, to the extent such award is outstanding and has not vested as of the
Executive’s Severance Date, shall automatically become fully vested as of the
Severance Date. In the event that the Executive has a Qualifying Termination
during the Protected Period related to a Change in Control, any stock option or
other equity-based award granted by the Company to the Executive, to the extent
such award had not vested and was cancelled or otherwise terminated upon or
prior to the date of the related Change in Control solely as a result of such
Qualifying Termination, shall be reinstated and shall automatically become fully
vested, and, in the case of stock options or similar awards, the Executive shall
be given a reasonable opportunity to exercise such accelerated portion of the
option or other award before it terminates.

3.4. Termination Due to Disability or Death. Termination of the Executive’s
employment due to the Executive’s death or Disability is not a Qualifying
Termination, and upon any such termination, the Executive shall be entitled to
payment only of the Accrued Obligations.

3.5. Termination for Cause or by the Executive Other Than for Good Reason
Termination of the Executive’s employment by the Company for Cause or by the
Executive other than for Good Reason does not constitute a Qualifying
Termination. Upon any such termination, the Executive shall be entitled to
payment only of the Accrued Obligations.

 

9

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

3.6. Notice of Termination. Any termination of the Executive’s employment by the
Company for Cause or by the Executive for Good Reason shall be communicated by a
Notice of Termination. For purposes of this Agreement, a “Notice of Termination”
shall mean a written notice which shall indicate the specific termination
provision in this Agreement relied upon, and shall set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Executive’s employment under the provision so indicated.

3.7. Release. This Section 3.7 shall apply notwithstanding anything else
contained in this Agreement to the contrary. As a condition precedent to any
Company obligation to the Executive pursuant to Section 3.3, the Executive (or,
in the event of the Executive’s death following a Qualifying Termination, the
Executive’s estate) shall, upon or promptly following (and in all events within
forty-five (45) days following) the Executive’s Severance Date (or, if later,
the date of the relevant Change in Control of the Company), provide the Company
with a valid, executed, written release of claims (in the form attached hereto
as Exhibit A or such similar form as the Company may reasonably require in the
circumstances) (the “Release”), and such Release shall have not been revoked by
the Executive (or the Executive’s estate, as applicable) pursuant to any
revocation rights afforded by applicable law. The Company shall provide the
final form of release agreement to the Executive not later than seven (7) days
following the Severance Date. The Company shall have no obligation to make any
payment or provide any benefit to the Executive pursuant to Section 3.3 unless
and until the Release contemplated by this Section 3.7 becomes irrevocable by
the Executive (or the Executive’s estate, as applicable) in accordance with all
applicable laws, rules and regulations.

3.8. Exclusive Remedy. The Executive agrees that the payments and benefits
contemplated by Section 3.3 shall, if the Release contemplated by Section 3.7 is
signed and the amounts paid, constitute the exclusive and sole remedy for any
termination of his or her employment and in such case the Executive covenants
not to assert or pursue any other remedies, at law or in equity, with respect to
any termination of employment. The Company and the Executive acknowledge and
agree that there is no duty of the Executive to mitigate damages under this
Agreement, and there shall be no offset against any amounts due to the Executive
under this Agreement on account of any remuneration attributable to any
subsequent employment that the Executive may obtain.

Article 4. Form and Timing of Severance Benefits; Tax Withholding

4.1. Form and Timing of Severance Benefits. Subject to Section 3.7, the
Severance Benefits described in Section 3.3(a) shall be paid in cash to the
Executive in a single lump sum as soon as practicable following (and in all
events within sixty (60) days following) the later of (i) the Executive’s
Separation from Service or (ii) in the case of a Separation from Service during
the Protected Period, the date of the corresponding Change in Control; provided,
however, that such payment shall be subject to the provisions of
Section 8.14(a); and, provided, further, that if the 60-day period following the
Executive’s Separation from Service (or Change in Control, as applicable) spans
two calendar years, the payment shall be made to Executive in the second of
those two calendar years.

 

10

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

4.2. Withholding of Taxes. Notwithstanding anything else herein to the contrary,
the Company may withhold (or cause there to be withheld, as the case may be)
from any amounts otherwise due or payable under or pursuant to this Agreement
such federal, state and local income, employment, or other taxes as may be
required to be withheld pursuant to any applicable law or regulation.

Article 5. Section 280G. Notwithstanding any other provision herein, the
Executive shall be covered by the provisions set forth in Exhibit B hereto,
incorporated herein by this reference.

Article 6. The Company’s Payment Obligation

6.1. Payment of Obligations Absolute. Except as provided in Sections 3.7, 4.2
and in Article 5, the Company’s obligation to make the payments and the
arrangements provided for herein shall be absolute and unconditional, and shall
not be affected by any circumstances, including, without limitation, any offset,
counterclaim, recoupment, defense, or other right which the Company may have
against the Executive or anyone else. All amounts payable by the Company
hereunder shall be paid without notice or demand. Each and every payment made
hereunder by the Company shall be final, and the Company shall not seek to
recover all or any part of such payment from the Executive or from whoever may
be entitled thereto, for any reasons whatsoever, except as otherwise provided in
Article 5; provided that the Executive does not revoke the Release or otherwise
take action to render the Release unenforceable.

6.2. Contractual Right to Benefits. This Agreement establishes and vests in the
Executive a contractual right to the benefits to which he or she is entitled
hereunder. The Company expressly waives any ability, if possible, to deny
liability for any breach of its contractual commitment hereunder upon the
grounds of lack of consideration, accord and satisfaction or any other defense.
In any dispute arising after a Change in Control as to whether the Executive is
entitled to benefits under this Agreement, there shall be a presumption that the
Executive is entitled to such benefits and the burden of proving otherwise shall
be on the Company. However, nothing herein contained shall require or be deemed
to require, or prohibit or be deemed to prohibit, the Company to segregate,
earmark, or otherwise set aside any funds or other assets, in trust or
otherwise, to provide for any payments to be made or required hereunder.

6.3. Pension Plans; Duplicate Benefits. All payments, benefits and amounts
provided under this Agreement shall be in addition to and not in substitution
for any pension rights under the Company’s tax-qualified pension plans,
supplemental retirement plans, nonqualified deferred compensation plans, bonus
plans, and any disability, workers’ compensation or other Company benefit plan
distribution that the Executive is entitled to as of his or her Severance Date.
Notwithstanding the foregoing, this Agreement shall not create an inference that
any duplicate payments shall be required. No payments made pursuant to this
Agreement shall be considered compensation for purposes of any such benefit
plan.

Article 7. Successors and Assignment

7.1. Successors to the Company. The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation, or otherwise) of all or
substantially all of the business and/or assets of the Company or of any
division or subsidiary thereof (the business

 

11

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

and/or assets of which constitute at least fifty percent (50%) of the total
business and/or assets of the Company) to expressly assume and agree to perform
the Company’s obligations under this Agreement in the same manner and to the
same extent that the Company would be required to perform them if such
succession had not taken place.

7.2. Assignment by the Executive. This Agreement shall inure to the benefit of
and be enforceable by the Executive’s personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees, and
legatees.

Article 8. Miscellaneous

8.1. Employment Status. Except as may be provided under any other written
agreement between the Executive and the Company, the employment of the Executive
by the Company is “at will,” and, prior to the effective date of a Change in
Control, may be terminated by either the Executive or the Company at any time,
subject to applicable law.

8.2. Beneficiaries. The Executive may designate one or more persons or entities
as the primary and/or contingent Beneficiaries of any Severance Benefits owing
to the Executive under this Agreement. If the Executive dies while any amount
would still be payable to him or her hereunder had he or she continued to live,
all such amounts, unless otherwise provided herein, shall be paid to the
Executive’s Beneficiary in accordance with the terms of this Agreement. If the
Executive has not named a Beneficiary, then such amounts shall be paid to the
Executive’s devisee, legatee, or other designee, or if there is no such
designee, to the Executive’s estate. The Executive may make or change such
designation at any time, provided that any designation or change thereto must be
in the form of a signed writing acceptable to and received by the Committee.

8.3. Gender and Number. Where the context requires herein, the singular shall
include the plural, the plural shall include the singular, and any gender shall
include all other genders.

8.4. Section Headings. The section headings of, and titles of paragraphs and
subparagraphs contained in, this Agreement are for the purpose of convenience
only, and they neither form a part of this Agreement nor are they to be used in
the construction or interpretation thereof.

8.5. Severability. If any provision of this Agreement or the application thereof
is held invalid, the invalidity shall not affect other provisions or
applications of this Agreement which can be given effect without the invalid
provisions or applications and to this end the provisions of this Agreement are
declared to be severable.

8.6. Entire Agreement. This Agreement, together with any employment agreement
and any written agreement evidencing any stock option or other equity-based
incentive award previously granted by the Company, embodies the entire agreement
of the parties hereto respecting the matters within its scope. As of the date
hereof, this Agreement shall supersede all other agreements of the parties
hereto that are prior to or contemporaneous with such date and that directly or
indirectly bear upon the subject matter hereof, other than any prior agreement
relating to any right to indemnification the Executive may have from the Company
or the

 

12

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

Executive’s right to be covered under any applicable insurance policy, with
respect to any liability the Executive incurred or may incur as an employee,
officer or director of the Company or its affiliates. Any negotiations,
correspondence, agreements, proposals or understandings prior to the date of
this Agreement relating to the subject matter hereof shall be deemed to have
been merged into this Agreement, and to the extent inconsistent herewith, such
negotiations, correspondence, agreements, proposals, or understandings shall be
deemed to be of no force or effect. There are no representations, warranties, or
agreements, whether express or implied, or oral or written, with respect to the
subject matter hereof, except as expressly set forth herein. This Agreement is
an integrated agreement.

8.7. Modification. This Agreement may not be amended, modified or changed (in
whole or in part), except by a formal, definitive written agreement expressly
referring to this Agreement, which agreement is executed by both of the parties
hereto.

8.8. Waiver. Neither the failure nor any delay on the part of a party to
exercise any right, remedy, power or privilege under this Agreement shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, remedy, power or privilege preclude any other or further exercise of the
same or of any right, remedy, power or privilege, nor shall any waiver of any
right, remedy, power or privilege with respect to any occurrence be construed as
a waiver of such right, remedy, power or privilege with respect to any other
occurrence. No waiver shall be effective unless it is in writing and is signed
by the party asserted to have granted such waiver.

8.9. Arbitration. Any controversy arising out of or relating to this Agreement,
its enforcement or interpretation, or because of an alleged breach, default, or
misrepresentation in connection with any of its provisions, or any other
controversy arising out of the Executive’s employment, including, but not
limited to, any state or federal statutory claims, shall be submitted to
arbitration in Orange County, California, before a sole arbitrator selected from
Judicial Arbitration and Mediation Services, Inc., Orange, California, or its
successor (“JAMS”), or if JAMS is no longer able to supply the arbitrator, such
arbitrator shall be selected from the American Arbitration Association, and
shall be conducted in accordance with the provisions of California Code of Civil
Procedure §§ 1280 et seq. as the exclusive forum for the resolution of such
dispute; provided, however, that provisional injunctive relief may, but need
not, be sought by either party to this Agreement in a court of law while
arbitration proceedings are pending, and any provisional injunctive relief
granted by such court shall remain effective until the matter is finally
determined by the Arbitrator. Final resolution of any dispute through
arbitration may include any remedy or relief which the Arbitrator deems just and
equitable, including any and all remedies provided by applicable state or
federal statutes. At the conclusion of the arbitration, the Arbitrator shall
issue a written decision that sets forth the essential findings and conclusions
upon which the Arbitrator’s award or decision is based. Any award or relief
granted by the Arbitrator hereunder shall be final and binding on the parties
hereto and may be enforced by any court of competent jurisdiction. The parties
hereto acknowledge and agree that they are hereby waiving any rights to trial by
jury in any action, proceeding or counterclaim brought by either of the parties
hereto against the other in connection with any matter whatsoever arising out of
or in any way connected with this Agreement or the Executive’s employment. The
parties agree hereto that the Company shall be responsible for payment of the
forum costs of any arbitration hereunder, including the Arbitrator’s fee. The
Executive and the Company further agree that in any proceeding to enforce the
terms of this Agreement, the prevailing party shall be entitled to its

 

13

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

or his or her reasonable attorneys’ fees and costs (other than forum costs
associated with the arbitration) incurred by it or him or her in connection with
resolution of the dispute in addition to any other relief granted.
Notwithstanding this provision, the parties hereto may mutually agree to mediate
any dispute prior to or following submission to arbitration.

8.10. Notices.

 

  (a) All notices, requests, demands and other communications required or
permitted under this Agreement shall be in writing and shall be deemed to have
been duly given and made if (i) delivered by hand, (ii) otherwise delivered
against receipt therefor, or (iii) sent by registered or certified mail, postage
prepaid, return receipt requested. Any notice shall be duly addressed to the
parties hereto as follows:

(i) if to the Company:

QLogic Corporation

26650 Aliso Viejo Parkway

Aliso Viejo, California 92656

Attn: General Counsel

with a copy to:

O’Melveny & Myers LLP

610 Newport Center Drive, Suite 1700

Newport Beach, California 92660

Attn: Gary Singer, Esq.

(ii) if to the Executive, at the last address of the Executive on the books of
the Company.

 

  (b) Any party may alter the address to which communications or copies are to
be sent by giving notice of such change of address in conformity with the
provisions of this Section 8.10 for the giving of notice. Any communication
shall be effective when delivered by hand, when otherwise delivered against
receipt therefor, or five (5) business days after being mailed in accordance
with the foregoing.

8.11. Legal Counsel; Mutual Drafting. Each party recognizes that this is a
legally binding contract and acknowledges and agrees that they have had the
opportunity to consult with legal counsel of their choice. Each party has
cooperated in the drafting, negotiation and preparation of this Agreement.
Hence, in any construction to be made of this Agreement, the same shall not be
construed against either party on the basis of that party being the drafter of
such language. The Executive agrees and acknowledges that he or she has read and
understands this Agreement completely, is entering into it freely and
voluntarily, and has been advised to seek counsel prior to entering into this
Agreement and has had ample opportunity to do so.

8.12. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original as against any party
whose signature appears thereon, and all of which together shall constitute one
and the same instrument. This Agreement shall

 

14

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

become binding when one or more counterparts hereof, individually or taken
together, shall bear the signatures of all of the parties hereto reflected
hereon as the signatories. Photographic copies of such signed counterparts may
be used in lieu of the originals for any purpose.

8.13. Governing Law. This Agreement, and all questions relating to its validity,
interpretation, performance and enforcement, as well as the legal relations
hereby created between the parties hereto, shall be governed by and construed
under, and interpreted and enforced in accordance with, the laws of the State of
California, notwithstanding any California or other conflict of law provision to
the contrary.

8.14. Section 409A.

 

  (a) Notwithstanding any provision of this Agreement to the contrary, if the
Executive is a “specified employee” within the meaning of Treasury Regulation
Section 1.409A-1(i) as of the date of the Executive’s Separation from Service,
the Executive shall not be entitled to any payment pursuant to Section 3.3 until
the earlier of (i) the date which is six (6) months after the Executive’s
Separation from Service for any reason other than death, or (ii) the date of the
Executive’s death. Any amounts otherwise payable to the Executive upon or in the
six (6) month period following the Executive’s Separation from Service that are
not so paid by reason of this Section 8.14(a) shall be paid (without interest)
as soon as practicable (and in all events within thirty (30) days) after the
date that is six (6) months after the Executive’s Separation from Service (or,
if earlier, as soon as practicable, and in all events within thirty (30) days,
after the date of the Executive’s death). The provisions of this Section 8.14(a)
shall only apply if, and to the extent, required to avoid the imputation of any
tax, penalty or interest pursuant to Section 409A of the Code.

 

  (b) It is intended that any amounts payable under this Agreement shall either
be exempt from or comply with Section 409A of the Code (including the Treasury
regulations and other published guidance relating thereto) so as not to subject
the Executive to payment of any additional tax, penalty or interest imposed
under Code Section 409A. The provisions of this Agreement shall be construed and
interpreted to avoid the imputation of any such additional tax, penalty or
interest under Code Section 409A yet preserve (to the nearest extent reasonably
possible) the intended benefit payable to the Executive.

8.15. Clawback Rules and Policy. Notwithstanding anything else contained in this
Agreement to the contrary, this Agreement and all forms of compensation referred
to in this Agreement are subject to the Company’s clawback policy, as well as
the “clawback” provisions of applicable law, rules and regulations, as each may
be adopted and in effect from time to time (collectively, the “Clawback
Policy”). Pursuant to the Clawback Policy, the Company may recoup payments under
this Agreement to the extent that any such payments were based on incorrect
financial results that require a restatement of the Company’s financial
statements from senior level employees whose fraud or misconduct was a material
contributing factor to the financial restatement. The provisions of the Clawback
Policy are in addition to (and not in lieu of) any rights to repayment the
Company may have under Section 304 of the Sarbanes-Oxley Act of 2002 and other
applicable laws.

EXHIBIT A

GENERAL RELEASE AGREEMENT

1. Release. [Name] (“Executive”), on his or her own behalf and on behalf of his
or her descendants, dependents, heirs, executors, administrators, assigns and
successors, and each of them, hereby acknowledges full and complete satisfaction
of and releases and discharges and covenants not to sue QLogic Corporation (the
“Company”), its divisions, subsidiaries, parents, or affiliated corporations,
past and present, and each of them, as well as its and their assignees,
successors, directors, officers, shareholders, partners, representatives,
attorneys, agents or employees, past or present, or any of them (individually
and collectively, “Releasees”), from and with respect to any and all claims,
agreements, obligations, demands and causes of action, known or unknown,
suspected or unsuspected, arising out of or in any way connected with
Executive’s employment or any other relationship with or interest in the Company
or the termination thereof, including without limiting the generality of the
foregoing, any claim for severance pay, profit sharing, bonus or similar
benefit, equity-based awards and/or dividend equivalents thereon, pension,
retirement, life insurance, health or medical insurance or any other fringe
benefit, or disability, or any other claims, agreements, obligations, demands
and causes of action, known or unknown, suspected or unsuspected resulting from
any act or omission by or on the part of Releasees committed or omitted prior to
the date of this Agreement, including, without limiting the generality of the
foregoing, any claim under Title VII of the Civil Rights Act of 1964, the
Americans with Disabilities Act, the California Fair Employment and Housing Act,
or the California Family Rights Act, or any other federal, state or local law,
regulation or ordinance (collectively, the “Claims”); provided, however, that
the foregoing release does not apply to any obligation of the Company to
Executive pursuant to any of the following: (1) Section 3 of the Change in
Control Severance Agreement dated as of [            , 2011] by and between the
Company and Executive (the “Change in Control Agreement”), or (2) any
equity-based awards previously granted by the Company to Executive (as amended
by the Change in Control Agreement). In addition, this release does not cover
any Claim that cannot be so released as a matter of applicable law. Executive
acknowledges and agrees that he or she has received any and all leave and other
benefits that he or she has been and is entitled to pursuant to the Family and
Medical Leave Act of 1993.

2. Acknowledgement of Payment of Wages. Executive acknowledges that he or she
has received all amounts owed for his or her regular and usual salary
(including, but not limited to, any bonus or other wages), and usual benefits
through the date of this Agreement.

3. Waiver of Civil Code Section 1542. This Agreement is intended to be effective
as a general release of and bar to each and every Claim hereinabove specified.
Accordingly, Executive hereby expressly waives any rights and benefits conferred
by Section 1542 of the California Civil Code as to the Claims. Section 1542 of
the California Civil Code provides:

“A GENERAL RELEASE DOES NOT EXTEND TO A CLAIM WHICH THE CREDITOR DOES NOT KNOW
OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE,
WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT
WITH THE DEBTOR.”

 

A-1

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

Executive acknowledges that he or she later may discover claims, demands, causes
of action or facts in addition to or different from those which Executive now
knows or believes to exist with respect to the subject matter of this Agreement
and which, if known or suspected at the time of executing this Agreement, may
have materially affected its terms. Nevertheless, Executive hereby waives, as to
the Claims, any claims, demands, and causes of action that might arise as a
result of such different or additional claims, demands, causes of action or
facts.

4. ADEA Waiver. Executive expressly acknowledges and agrees that by entering
into this Agreement, he or she is waiving any and all rights or claims that he
or she may have arising under the Age Discrimination in Employment Act of 1967,
as amended (“ADEA”), which have arisen on or before the date of execution of
this Agreement. Executive further expressly acknowledges and agrees that:

(a) In return for this Agreement, he or she will receive consideration beyond
that which he or she was already entitled to receive before entering into this
Agreement;

(b) He or she is hereby advised in writing by this Agreement to consult with an
attorney before signing this Agreement;

(c) He or she was given a copy of this Agreement on [            , 20    ] and
informed that he or she had twenty-one (21) days within which to consider the
Agreement and that if he or she wished to execute this Agreement prior to
expiration of such 21-day period, he or she should execute the Acknowledgement
and Waiver attached hereto as Exhibit A-1;

(d) Nothing in this Agreement prevents or precludes Executive from challenging
or seeking a determination in good faith of the validity of this waiver under
the ADEA, nor does it impose any condition precedent, penalties or costs from
doing so, unless specifically authorized by federal law; and

(e) He or she was informed that he or she has seven (7) days following the date
of execution of this Agreement in which to revoke this Agreement, and this
Agreement will become null and void if Executive elects revocation during that
time. Any revocation must be in writing and must be received by the Company
during the seven-day revocation period. In the event that Executive exercises
his or her right of revocation, neither the Company nor Executive will have any
obligations under this Agreement.

5. No Transferred Claims. Executive represents and warrants to the Company that
he or she has not heretofore assigned or transferred to any person not a party
to this Agreement any released matter or any part or portion thereof.

6. Miscellaneous. The following provisions shall apply for purposes of this
Agreement:

(a) Number and Gender. Where the context requires, the singular shall include
the plural, the plural shall include the singular, and any gender shall include
all other genders.

 

A-2

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

(b) Section Headings. The section headings of, and titles of paragraphs and
subparagraphs contained in, this Agreement are for the purpose of convenience
only, and they neither form a part of this Agreement nor are they to be used in
the construction or interpretation thereof.

(c) Governing Law. This Agreement, and all questions relating to its validity,
interpretation, performance and enforcement, as well as the legal relations
hereby created between the parties hereto, shall be governed by and construed
under, and interpreted and enforced in accordance with, the laws of the State of
California, notwithstanding any California or other conflict of law provision to
the contrary.

(d) Severability. If any provision of this Agreement or the application thereof
is held invalid, the invalidity shall not affect other provisions or
applications of this Agreement which can be given effect without the invalid
provisions or applications and to this end the provisions of this Agreement are
declared to be severable.

(e) Modifications. This Agreement may not be amended, modified or changed (in
whole or in part), except by a formal, definitive written agreement expressly
referring to this Agreement, which agreement is executed by both of the parties
hereto.

(f) Waiver. Neither the failure nor any delay on the part of a party to exercise
any right, remedy, power or privilege under this Agreement shall operate as a
waiver thereof, nor shall any single or partial exercise of any right, remedy,
power or privilege preclude any other or further exercise of the same or of any
right, remedy, power or privilege, nor shall any waiver of any right, remedy,
power or privilege with respect to any occurrence be construed as a waiver of
such right, remedy, power or privilege with respect to any other occurrence. No
waiver shall be effective unless it is in writing and is signed by the party
asserted to have granted such waiver.

(g) Arbitration. Any controversy arising out of or relating to this Agreement
shall be submitted to arbitration in accordance with the arbitration provisions
of the Change in Control Agreement.

(h) Counterparts. This Agreement may be executed in any number of counterparts,
each of which shall be deemed an original as against any party whose signature
appears thereon, and all of which together shall constitute one and the same
instrument. This Agreement shall become binding when one or more counterparts
hereof, individually or taken together, shall bear the signatures of all of the
parties reflected hereon as the signatories. Photographic copies of such signed
counterparts may be used in lieu of the originals for any purpose.

EXHIBIT B

SECTION 280G PROVISIONS

 

1.1 Limitation on Payments. If upon or following a Change of Control the tax
imposed by Section 4999 of the Code, or any similar or successor tax (the
“Excise Tax”) would apply absent this Section 1.1, because of the Change of
Control, to any payments, benefits and/or amounts received by Executive as
severance benefits or otherwise, including, without limitation, any amounts
received or deemed received, within the meaning of any provision of the Code, by
Executive as a result of (and not by way of limitation) any automatic vesting,
lapse of restrictions and/or accelerated target or performance achievement
provisions, or otherwise, applicable to outstanding grants or awards to
Executive under any of the Company’s equity incentive plans or agreements
(collectively, the “Total Payments”), then Executive’s benefits under this
Agreement shall be either (a) delivered in full, or (b) delivered as to such
lesser extent which would result in no portion of such benefits being subject to
the Excise Tax, whichever of the foregoing amounts, taking into account the
applicable federal, state and local income taxes and the Excise Tax, results in
the receipt by Executive on an after-tax basis, of the greatest amount of
benefits, notwithstanding that all or some portion of such benefits may be
taxable under Section 4999 of the Code. The Company shall reduce or eliminate
the Total Payments by first reducing or eliminating any cash severance benefits,
then by reducing or eliminating any accelerated vesting of stock options, then
by reducing or eliminating any accelerated vesting of other equity-based awards,
then by reducing or eliminating any other remaining Total Payments.

 

1.2 Determination. Any determination required under this section shall be made
in writing by PwC (or another national public accounting firm mutually
acceptable to the parties) (the “Accountants”), whose determination shall be
conclusive and binding upon the Executive and the Company for all purposes. For
purposes of making the calculations required by this section, the Accountants
may make reasonable assumptions and approximations concerning applicable taxes
and may rely on reasonable, good faith interpretations concerning the
application of Sections 280G and 4999 of the Code. The Company and the Executive
shall furnish to the Accountants such information and documents as the
Accountants may reasonably request in order to make a determination under this
section. The Company shall bear all costs the Accountants may reasonably incur
in connection with any calculations contemplated by this section.
