purpose of the Plan is to promote the long-term success of the Company and the creation of stockholder value by (a) encouraging Employees, Outside Directors and Consultants to focus on critical long-range objectives, (b) encouraging the attraction
and retention of Employees, Outside Directors and Consultants with exceptional qualifications and (c) linking Employees, Outside Directors and Consultants directly to stockholder interests through increased stock ownership. The Plan seeks to achieve
this purpose by providing for Awards in the form of restricted shares, stock units, options (which may constitute incentive stock options or nonstatutory stock options) or stock appreciation rights.

                 (B) Were elected, or nominated for election, to the Board of Directors with the affirmative votes of at least a majority of the aggregate of the

         (ii) Any “person”
(as defined below) who by the acquisition or aggregation of securities, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 50% or more

reduction in the aggregate number of outstanding shares of Base Capital Stock, and any decrease thereafter in such person’s ownership of securities, shall be disregarded until such person increases in any manner, directly or indirectly, such
person’s beneficial ownership of any securities of the Company; or 
  
         (iii) The consummation of a merger or consolidation of the Company with or into another entity or any other corporate reorganization, if persons who were not

 pursuant to such plan after the effective date of this Plan) and (y) an annual increase on the first day of each fiscal year during the term of the Plan, beginning
January 1, 2005, in each case in an amount equal to the lesser of (i) 3,750,000 Shares, (ii) 5% of the outstanding Shares on the last

day of the immediately preceding year, or (iii) an amount determined by the Board. The limitations of this Section 5(a) shall be subject to adjustment
pursuant to Section 11. The number of Shares that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of Shares which then remain available for issuance under the Plan. The Company, during the
term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. 
  
 (b) 
Option/SAR Limitation. Subject to the provisions of Section 11, no Participant may receive Options or SARs under the Plan in any calendar year that relate to more than 937,500 Shares, except that grants to a
Participant in the calendar year in which his or her service first commences shall not relate to more than 2,250,000 Shares. 
  
 (c) Additional Shares. If Restricted Shares or Shares issued upon the exercise of Options are forfeited, then such Shares shall again become
available for Awards under the Plan. If Stock Units, Options or SARs are forfeited or terminate for any other reason before being exercised, then the corresponding Shares shall again become available for Awards under the Plan. If Stock Units are
settled, then only the number of Shares (if any) actually issued in settlement of such Stock Units shall reduce the number available under Section 5(a) and the balance shall again become available for Awards under the Plan. If SARs are exercised,
then only the number of Shares (if any) actually issued in settlement of such SARs shall reduce the number available in Section 5(a) and the balance shall again become available for Awards under the Plan. 
  
 SECTION 6.
RESTRICTED SHARES 
  
 (a)

Restricted Stock Agreement. Each grant of Restricted Shares under the Plan shall be evidenced by a Restricted Stock Agreement between the recipient and the Company. Such Restricted Shares shall be subject to all
applicable terms of the Plan and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Restricted Stock Agreements entered into under the Plan need not be identical. 
  
 (b) 
Payment for Awards. Subject to the following sentence, Restricted Shares may be sold or awarded under the Plan for such consideration as the Committee may determine, including (without limitation) cash, cash
equivalents, full-recourse promissory notes, past services and future services. To the extent that an Award consists of newly issued Restricted Shares, the Award recipient shall furnish consideration with a value not less than the par value of such
Restricted Shares in the form of cash, cash equivalents, or past services rendered to the Company (or a Parent or Subsidiary), as the Committee may determine. 
  

(c) 
Vesting. Each Award of Restricted Shares may or may not be subject to vesting. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Restricted Stock Agreement. A
Restricted Stock Agreement may provide for accelerated vesting in the event of the Participant’s death, disability or retirement or other events. The Committee may determine, at the time of granting Restricted Shares of thereafter, that
all or part of such 

  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -9- 

 
Restricted Shares shall become vested in the event that a Change in Control occurs with respect to the Company. 
  
 (d) 
Voting and Dividend Rights. The holders of Restricted Shares awarded under the Plan shall have the same voting, dividend and other rights as the Company’s other stockholders. A Restricted Stock Agreement,
however, may require that the holders of Restricted Shares invest any cash dividends received in additional Restricted Shares. Such additional Restricted Shares shall be subject to the same conditions and restrictions as the Award with respect to
which the dividends were paid. 
  
 (e) 
Restrictions on Transfer of Shares. Restricted Shares shall be subject to such rights of repurchase, rights of first refusal or other restrictions as the Committee may determine. Such restrictions shall be set forth
in the applicable Restricted Stock Agreement and shall apply in addition to any general restrictions that may apply to all holders of Shares. 
  
 SECTION 7.
TERMS AND CONDITIONS OF OPTIONS 
  
 (a) 
Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms and conditions
of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Committee deems appropriate for inclusion in a Stock Option Agreement. The Stock Option Agreement shall specify whether the
Option is an ISO or an NSO. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. Options may be granted in consideration of a reduction in the Optionee’s other compensation. 
  
 (b) 
Number of Shares. Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 11. 
  
 (c) 
Exercise Price. Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the Fair Market Value of a Share on the date of grant, except as otherwise
provided in 4(c), and the Exercise Price of an NSO shall not be less 85% of the Fair Market Value of a Share on the date of grant. Notwithstanding the foregoing, a Stock Option Agreement may specify that the exercise price of an NSO may vary in
accordance with a predetermined formula. Subject to the foregoing in this Section 7(c), the Exercise Price under any Option shall be determined by the Committee at its sole discretion. The Exercise Price shall be payable in one of the forms
described in Section 8. 
  
 (d) 
Withholding Taxes. As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Committee may require for the satisfaction of any federal, state, local or foreign withholding tax
obligations that may arise in connection with such exercise. The Optionee shall also make such arrangements as the Committee may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in
connection with the disposition of Shares acquired by exercising an Option. 
  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -10- 

 (e) 
Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The Stock Option Agreement shall also specify the term of the Option;
provided that the term of an ISO shall in no event exceed 10 years from the date of grant (five years for Employees described in Section 4(c). A Stock Option Agreement may provide for accelerated exercisability in the event of the Optionee’s
death, disability, or retirement or other events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s Service. Options may be awarded in combination with SARs, and such an Award may
provide that the Options will not be exercisable unless the related SARs are forfeited. Subject to the foregoing in this Section 7(e), the Committee at its sole discretion shall determine when all or any installment of an Option is to become
exercisable and when an Option is to expire. 
  
 (f) 
Exercise of Options. Upon Termination of Service. Each Stock Option Agreement shall set forth the extent to which the Optionee shall have the right to exercise the Option following termination of the Optionee’s
Service with the Company and its Subsidiaries, and the right to exercise the Option of any executors or administrators of the Optionee’s estate or any person who has acquired such Option(s) directly from the Optionee by bequest or inheritance.
Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Options issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of Service. 
  
 (g) 
Effect of Change in Control. The Committee may determine, at the time of granting an Option or thereafter, that such Option shall become exercisable as to all or part of the Shares subject to such Option in the event
that a Change in Control occurs with respect to the Company. 
  
 (h) 
Leaves of Absence. An Employee’s Service shall cease when such Employee ceases to be actively employed by, or a Consultant to, the Company (or any subsidiary) as determined in the sole discretion of the Board of
Directors. For purposes of Options, Service does not terminate when an Employee goes on a bona fide leave of absence, that was approved by the Company in writing, if the terms of the leave provide for continued service crediting, or when continued
service crediting is required by applicable law. However, for purposes of determining whether an Option is entitled to ISO status, an Employee’s Service will be treated as terminating 90 days after such Employee went on leave, unless such
Employee’s right to return to active work is guaranteed by law or by a contract. Service terminates in any event when the approved leave ends, unless such Employee immediately returns to active work. The Company determines which leaves count
toward Service, and when Service terminates for all purposes under the Plan. 
  
 (i) 
No Rights as a Stockholder. An Optionee, or a transferee of an Optionee, shall have no rights as a stockholder with respect to any Shares covered by his Option until the date of the issuance of a stock certificate for
such Shares. No adjustments shall be made, except as provided in Section 11.

 (j) 
Modification, Extension and Renewal of Options. Within the limitations of the Plan, the Committee may modify, extend or renew outstanding options or may accept the cancellation of outstanding options (to the extent
not previously exercised), whether or not granted hereunder, in return for the grant of new Options for the same or a different number of Shares and at the same or a different exercise price, or in return for the grant of the same or a different
number of Shares. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, adversely affect his or her rights or obligations under such Option. 
  
 (k) 
Restrictions on Transfer of Shares. Any Shares issued upon exercise of an Option shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as
the Committee may determine. Such restrictions shall be set forth in the applicable Stock Option Agreement and shall apply in addition to any general restrictions that may apply to all holders of Shares. 
  
 (l) 
Buyout Provisions. The Committee may at any time (a) offer to buy out for a payment in cash or cash equivalents an Option previously granted or (b) authorize an Optionee to elect to cash out an Option previously
granted, in either case at such time and based upon such terms and conditions as the Committee shall establish. 
  
 SECTION 8.
PAYMENT FOR SHARES 
  
 (a) 
General Rule. The entire Exercise Price or Purchase Price of Shares issued under the Plan shall be payable in lawful money of the United States of America at the time when such Shares are purchased, except as provided
in Section 8(b) through Section 8(g) below. 
  
 (b) 
Surrender of Stock. To the extent that a Stock Option Agreement so provides, payment may be made all or in part by surrendering, or attesting to the ownership of, Shares which have already been owned by the Optionee
or his representative. Such Shares shall be valued at their Fair Market Value on the date when the new Shares are purchased under the Plan. The Optionee shall not surrender, or attest to the ownership of, Shares in payment of the Exercise Price if
such action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to the Option for financial reporting purposes. 
  
 (c) 
Services Rendered. At the discretion of the Committee, Shares may be awarded under the Plan in consideration of services rendered to the Company or a Subsidiary prior to the award. If Shares are awarded without the
payment of a Purchase Price in cash, the Committee shall make a determination (at the time of the award) of the value of the services rendered by the Offeree and the sufficiency of the consideration to meet the requirements of Section 6(b).

  
 (d) 
Cashless Exercise. To the extent that a Stock Option Agreement so provides, payment may be made all or in part by delivery (on a form prescribed by the Committee) of an irrevocable direction to a securities broker to
sell Shares and to deliver all or part of the sale proceeds to the Company in payment of the aggregate Exercise Price.  
  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -12- 

 (e) 
Exercise/Pledge. To the extent that a Stock Option Agreement so provides, payment may be made all or in part by delivery (on a form prescribed by the Committee) of an irrevocable direction to a securities broker or
lender to pledge Shares, as security for a loan, and to deliver all or part of the loan proceeds to the Company in payment of the aggregate Exercise Price. 
  
 (f) 
Promissory Note. To the extent that a Stock Option Agreement or Restricted Stock Agreement so provides, payment may be made all or in part by delivering (on a form prescribed by the Company) a full-recourse promissory
note. However, the par value of the Common Shares being purchased under the Plan, if newly issued, shall be paid in cash or cash equivalents. 
  
 (g) 
Other Forms of Payment. To the extent that a Stock Option Agreement or Restricted Stock Agreement so provides, payment may be made in any other form that is consistent with applicable laws, regulations and rules.

  
 (h) 
Limitations under Applicable Law. Notwithstanding anything herein or in a Stock Option Agreement or Restricted Stock Agreement to the contrary, payment may not be made in any form that is unlawful, as determined by
the Committee in its sole discretion. 
  
 SECTION 9.
STOCK APPRECIATION RIGHTS 
  
 (a) 
SAR Agreement. Each grant of a SAR under the Plan shall be evidenced by a SAR Agreement between the Optionee and the Company. Such SAR shall be subject to all applicable terms of the Plan and may be subject to any
other terms that are not inconsistent with the Plan. The provisions of the various SAR Agreements entered into under the Plan need not be identical. SARs may be granted in consideration of a reduction in the Optionee’s other compensation.

  
 (b) 
Number of Shares. Each SAR Agreement shall specify the number of Shares to which the SAR pertains and shall provide for the adjustment of such number in accordance with Section 11. 
  
 (c) 
Exercise Price. Each SAR Agreement shall specify the Exercise Price. A SAR Agreement may specify an Exercise Price that varies in accordance with a predetermined formula while the SAR is outstanding. 
  
 (d) 
Exercisability and Term. Each SAR Agreement shall specify the date when all or any installment of the SAR is to become exercisable. The SAR Agreement shall also specify the term of the SAR. A SAR Agreement may provide
for accelerated exercisability in the event of the Optionee’s death, disability or retirement or other events and may provide for expiration prior to the end of its term in the event of the termination of the Optionee’s service. SARs may
be awarded in combination with Options, and such an Award may provide that the SARs will not be exercisable unless the related Options are forfeited. A SAR may be included in an ISO only at the time of grant but may be included in an NSO at the time
of grant or thereafter. A SAR granted under the Plan may provide that it will be exercisable only in the event of a Change in Control. 
  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -13- 

 (e) 
Effect of Change in Control. The Committee may determine, at the time of granting a SAR or thereafter, that such SAR shall become fully exercisable as to all Common Shares subject to such SAR in the event that a
Change in Control occurs with respect to the Company. 
  
 (f)

Exercise of SARs. Upon exercise of a SAR, the Optionee (or any person having the right to exercise the SAR after his or her death) shall receive from the Company (a) Shares, (b) cash or (c) a combination of Shares and
cash, as the Committee shall determine. The amount of cash and/or the Fair Market Value of Shares received upon exercise of SARs shall, in the aggregate, be equal to the amount by which the Fair Market Value (on the date of surrender) of the Shares
subject to the SARs exceeds the Exercise Price. 
  
 (g)

Modification or Assumption of SARs. Within the limitations of the Plan, the Committee may modify, extend or assume outstanding SARs or may accept the cancellation of outstanding SARs (whether granted by the Company or
by another issuer) in return for the grant of new SARs for the same or a different number of shares and at the same or a different exercise price. The foregoing notwithstanding, no modification of a SAR shall, without the consent of the holder, may
alter or impair his or her rights or obligations under such SAR. 
  
 SECTION
10.
STOCK UNITS 
  
 (a) 
Stock Unit Agreement. Each grant of Stock Units under the Plan shall be evidenced by a Stock Unit Agreement between the recipient and the Company. Such Stock Units shall be subject to all applicable terms of the Plan
and may be subject to any other terms that are not inconsistent with the Plan. The provisions of the various Stock Unit Agreements entered into under the Plan need not be identical. Stock Units may be granted in consideration of a reduction in the
recipient’s other compensation. 
  
 (b) 
Payment for Awards. To the extent that an Award is granted in the form of Stock Units, no cash consideration shall be required of the Award recipients. 
  
 (c) 
Vesting Conditions. Each Award of Stock Units may or may not be subject to vesting. Vesting shall occur, in full or in installments, upon satisfaction of the conditions specified in the Stock Unit Agreement. A Stock
Unit Agreement may provide for accelerated vesting in the event of the Participant’s death, disability or retirement or other events. The Committee may determine, at the time of granting Stock Units or thereafter, that all or part of such Stock
Units shall become vested in the event that a Change in Control occurs with respect to the Company. 
  
 (d) 
Voting and Dividend Rights. The holders of Stock Units shall have no voting rights. Prior to settlement or forfeiture, any Stock Unit awarded under the Plan may, at the Committee’s discretion, carry with it a
right to dividend equivalents. Such right entitles the holder to be credited with an amount equal to all cash dividends paid on one Share while the Stock Unit is outstanding. Dividend equivalents may be converted into additional Stock Units.
Settlement of dividend equivalents may be made in the form of cash, in the form of Shares, or in 

  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -14- 

 
a combination of both. Prior to distribution, any dividend equivalents which are not paid shall be subject to the same conditions and restrictions (including
without limitation, any forfeiture conditions) as the Stock Units to which they attach. 
  
 (e) 
Form and Time of Settlement of Stock Units. Settlement of vested Stock Units may be made in the form of (a) cash, (b) Shares or (c) any combination of both, as determined by the Committee. The actual number of Stock
Units eligible for settlement may be larger or smaller than the number included in the original Award, based on predetermined performance factors. Methods of converting Stock Units into cash may include (without limitation) a method based on the
average Fair Market Value of Shares over a series of trading days. Vested Stock Units may be settled in a lump sum or in installments. The distribution may occur or commence when all vesting conditions applicable to the Stock Units have been
satisfied or have lapsed, or it may be deferred to any later date. The amount of a deferred distribution may be increased by an interest factor or by dividend equivalents. Until an Award of Stock Units is settled, the number of such Stock Units
shall be subject to adjustment pursuant to Section 11. 
  
 (f)

Death of Recipient. Any Stock Units Award that becomes payable after the recipient’s death shall be distributed to the recipient’s beneficiary or beneficiaries. Each recipient of a Stock Units Award under
the Plan shall designate one or more beneficiaries for this purpose by filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Award recipient’s
death. If no beneficiary was designated or if no designated beneficiary survives the Award recipient, then any Stock Units Award that becomes payable after the recipient’s death shall be distributed to the recipient’s estate. 

 
 (g) 
Creditors’ Rights. A holder of Stock Units shall have no rights other than those of a general creditor of the Company. Stock Units represent an unfunded and unsecured obligation of the Company, subject to the
terms and conditions of the applicable Stock Unit Agreement. 
  
 SECTION 11.
ADJUSTMENT OF SHARES 
  
 (a)

Adjustments. In the event of a subdivision of the outstanding Stock, a declaration of a dividend payable in Shares, a declaration of a dividend payable in a form other than Shares in an amount that has a material
effect on the price of Shares, a combination or consolidation of the outstanding Stock (by reclassification or otherwise) into a lesser number of Shares, a recapitalization, a spin-off or a similar occurrence, the Committee shall make such
adjustments as it, in its sole discretion, deems appropriate in one or more of: 
  
         (i) The number of Options, SARs, Restricted Shares and Stock Units available for future Awards under Section 5; 
  
         (ii) The limitations set
forth in Sections 5(a) and (b); 
  
         (iii) The number of NSOs to be granted to Outside Directors under Section 4(b); 
  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -15- 

         (iv) The number of Shares covered by each outstanding
Option and SAR; 
  
         (v) The Exercise Price under each outstanding Option and SAR; or 
  
         (vi) The number of Stock Units included in any prior Award which has not yet been settled. 
  
 Except as provided in this Section 11, a Participant shall have no rights by reason of any
issue by the Company of stock of any class or securities convertible into stock of any class, any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of
shares of stock of any class. 
  
 (b) 
Dissolution or Liquidation. To the extent not previously exercised or settled, Options, SARs and Stock Units shall terminate immediately prior to the dissolution or liquidation of the Company. 
  
 (c) 
Reorganizations. In the event that the Company is a party to a merger or other reorganization, outstanding Awards shall be subject to the agreement of merger or reorganization. Such agreement shall provide for:

  
         (i) The
continuation of the outstanding Awards by the Company, if the Company is a surviving corporation; 
  
         (ii) The assumption of the outstanding Awards by the surviving corporation or its parent or subsidiary;

  
         (iii) The
substitution by the surviving corporation or its parent or subsidiary of its own awards for the outstanding Awards; 
  
         (iv) Full exercisability or vesting and accelerated expiration of the outstanding Awards; or 

 
         (v) Settlement of the
full value of the outstanding Awards in cash or cash equivalents followed by cancellation of such Awards. 
  
 (d) 
Reservation of Rights. Except as provided in this Section 11, an Optionee or Offeree shall have no rights by reason of any subdivision or consolidation of shares of stock of any class, the payment of any dividend or
any other increase or decrease in the number of shares of stock of any class. Any issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

 SECTION 12.
DEFERRAL OF AWARDS 
  
 The
Committee (in its sole discretion) may permit or require a Participant to: 
  
 Have cash that otherwise would be paid to such Participant as a result of the exercise of a SAR or the settlement of Stock Units credited to a deferred compensation account established for such Participant by the
Committee as an entry on the Company’s books; 
  
 Have Shares
that otherwise would be delivered to such Participant as a result of the exercise of an Option or SAR converted into an equal number of Stock Units; or 
  
 Have Shares that otherwise would be delivered to such Participant as a result of the exercise of an Option or SAR or the settlement of Stock Units
converted into amounts credited to a deferred compensation account established for such Participant by the Committee as an entry on the Company’s books. Such amounts shall be determined by reference to the Fair Market Value of such Shares as of
the date when they otherwise would have been delivered to such Participant. 
  
 A deferred compensation account established under this Section 12 may be credited with interest or other forms of investment return, as determined by the Committee. A Participant for whom such an account is
established shall have no rights other than those of a general creditor of the Company. Such an account shall represent an unfunded and unsecured obligation of the Company and shall be subject to the terms and conditions of the applicable agreement
between such Participant and the Company. If the deferral or conversion of Awards is permitted or required, the Committee (in its sole discretion) may establish rules, procedures and forms pertaining to such Awards, including (without limitation)
the settlement of deferred compensation accounts established under this Section 12. 
  
 SECTION 13.
AWARDS UNDER OTHER PLANS 
  
 The
Company may grant awards under other plans or programs. Such awards may be settled in the form of Shares issued under this Plan. Such Shares shall be treated for all purposes under the Plan like Shares issued in settlement of Stock Units and shall,
when issued, reduce the number of Shares available under Section 5. 
  
 SECTION
14.
PAYMENT OF DIRECTOR’S FEES IN SECURITIES 
  
 (a) 
Effective Date. No provision of this Section 14 shall be effective unless and until the Board has determined to implement such provision. 
  
 (b) 
Elections to Receive NSOs, Restricted Shares or Stock Units. An Outside Director may elect to receive his or her annual retainer payments and/or meeting fees from the Company in the form of cash, NSOs, Restricted
Shares or Stock Units, or a combination thereof, as determined by the Board. Such NSOs, Restricted Shares and Stock Units shall be issued under the Plan. An election under this Section 14 shall be filed with the Company on the prescribed
form. 
  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -17- 

 (c) 
Number and Terms of NSOs, Restricted Shares or Stock Units. The number of NSOs, Restricted Shares or Stock Units to be granted to Outside Directors in lieu of annual retainers and meeting fees that would otherwise be
paid in cash shall be calculated in a manner determined by the Board. The terms of such NSOs, Restricted Shares or Stock Units shall also be determined by the Board. 
  
 SECTION 15.
LEGAL AND REGULATORY REQUIREMENTS 
  
 Shares shall not be issued under the Plan unless the issuance and delivery of such Shares complies with (or is exempt from) all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules
and regulations promulgated thereunder, state securities laws and regulations and the regulations of any stock exchange on which the Company’s securities may then be listed, and the Company has obtained the approval or favorable ruling from any
governmental agency which the Company determines is necessary or advisable. 
  
 SECTION 16.
WITHHOLDING TAXES 
  
 (a)

General. To the extent required by applicable federal, state, local or foreign law, a Participant or his or her successor shall make arrangements satisfactory to the Company for the satisfaction of any withholding
tax obligations that arise in connection with the Plan. The Company shall not be required to issue any Shares or make any cash payment under the Plan until such obligations are satisfied. 
  
 (b) 
Share Withholding. The Committee may permit a Participant to satisfy all or part of his or her withholding or income tax obligations by having the Company withhold all or a portion of any Shares that otherwise would
be issued to him or her or by surrendering all or a portion of any Shares that he or she previously acquired. Such Shares shall be valued at their Fair Market Value on the date when taxes otherwise would be withheld in cash. In no event may a
Participant have Shares withheld that would otherwise be issued to him or her in excess of the number necessary to satisfy the legally required minimum tax withholding. 
  
 SECTION 17.
LIMITATION ON PARACHUTE PAYMENTS 
  
 (a) 
Scope of Limitation. This Section 17 shall apply to an Award only if the independent auditors most recently selected by the Board (the “Auditors”) determine that the after-tax value of such Award to the
Optionee or Offeree, taking into account the effect of all federal, state and local income taxes, employment taxes and excise taxes applicable to the Optionee or Offeree (including the excise tax under section 4999 of the Code), will be greater
after the application of this Section 17 than it was before application of this Section 17. 
  
 (b) 
Basic Rule. In the event that the Auditors determine that any payment or transfer by the Company under the Plan to or for the benefit of a Participant (a “Payment”) would be nondeductible by the Company for
federal income tax purposes because of the provisions concerning “excess parachute payments” in Section 280G of the Code, then the aggregate present value of all Payments shall be reduced (but not below zero) to the Reduced Amount. For

  

 ATHEROS COMMUNICATIONS, INC. 
 2004 STOCK INCENTIVE PLAN 
  

 -18- 

 
purposes of this Section 17, the “Reduced Amount” shall be the amount, expressed as a present value, which maximizes the aggregate present value of
the Payments without causing any Payment to be nondeductible by the Company because of Section 280G of the Code. 
  
 (c) 
Reduction of Payments. If the Auditors determine that any Payment would be nondeductible by the Company because of Section 280G of the Code, then the Company shall promptly give the Participant notice to that effect
and a copy of the detailed calculation thereof and of the Reduced Amount, and the Participant may then elect, in his or her sole discretion, which and how much of the Payments shall be eliminated or reduced (as long as after such election the
aggregate present value of the Payments equals the Reduced Amount) and shall advise the Company in writing of his or her election within 10 days of receipt of notice. If no such election is made by the Participant within such 10-day period, then the
Company may elect which and how much of the Payments shall be eliminated or reduced (as long as after such election the aggregate present value of the Payments equals the Reduced Amount) and shall notify the Participant promptly of such election.
For purposes of this Section 17, present value shall be determined in accordance with Section 280G(d)(4) of the Code. All determinations made by the Auditors under this Section 17 shall be binding upon the Company and the Participant and shall be
made within 60 days of the date when a Payment becomes payable or transferable. As promptly as practicable following such determination and the elections hereunder, the Company shall pay or transfer to or for the benefit of the Participant such
amounts as are then due to him or her under the Plan and shall promptly pay or transfer to or for the benefit of the Participant in the future such amounts as become due to him or her under the Plan. 
  
 (d) 
Related Corporations. For purposes of this Section 17, the term “Company” shall include affiliated corporations to the extent determined by the Auditors in accordance with Section 280G(d)(5) of the Code.

  
 SECTION 18.
NO EMPLOYMENT RIGHTS 
  
 No
provision of the Plan, nor any right or Option granted under the Plan, shall be construed to give any person any right to become, to be treated as, or to remain an Employee. The Company and its Subsidiaries reserve the right to terminate any
person’s Service at any time and for any reason, with or without notice. 
  
 SECTION 19.
