enrollment form with the Company at the prescribed location at any time. Payroll withholding shall cease as soon as reasonably practicable after such form has been received by the Company. In addition, employee contributions may be discontinued

 SECTION 6 Withdrawal From The Plan. 
 (a) Withdrawal. A Participant may elect to withdraw from the Plan by filing the prescribed form with the Company at the prescribed location at any
time before the last day of an Offering Period. As soon as reasonably practicable thereafter, payroll deductions shall cease and the entire amount credited to the Participant’s Plan Account shall be refunded to him or her in cash, without
interest. No partial withdrawals shall be permitted. 
 (b) Re-enrollment After Withdrawal. A former Participant who has withdrawn
from the Plan shall not be a Participant until he or she re-enrolls in the Plan under Section 4(b). Re-enrollment may be effective only at the commencement of an Offering Period. 
 SECTION 7 Change In Employment Status. 
 (a) Termination of Employment. Termination of employment as an Eligible Employee for any reason, including death, shall be treated as an automatic withdrawal from the Plan under Section 6(a). A transfer
from one Participating Company to another shall not be treated as a termination of employment. 
 (b) Leave of Absence. For purposes
of the Plan, employment shall not be deemed to terminate when the Participant goes on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company in writing. Employment, however, shall be deemed to
terminate 90 days after the Participant goes on a leave, unless a contract or statute guarantees his or her right to return to work. Employment shall be deemed to terminate in any event when the approved leave ends, unless the Participant
immediately returns to work. 
 (c) Death. In the event of the Participant’s death, the amount credited to his or her Plan
Account shall be paid to a beneficiary designated by him or her for this purpose on the prescribed form or, if none, to the Participant’s estate. Such form shall be valid only if it was filed with the Company at the prescribed location before
the Participant’s death. 
 SECTION 8 Plan Accounts And Purchase Of Shares. 
 (a) Plan Accounts. The Company shall maintain a Plan Account on its books in the name of each Participant. Whenever an amount is deducted from the
Participant’s Compensation under the Plan, such amount shall be credited to the Participant’s Plan Account. Amounts credited to Plan Accounts shall not be trust funds and may be commingled with the Company’s general assets and applied
to general corporate purposes. No interest shall be credited to Plan Accounts. 
 (b) Purchase Price. 
 (i) The Purchase Price for each share of Stock purchased at the close of an Offering Period beginning on or after May 5, 2006, shall
be the lower of (a) 85% of the Fair Market Value of such share on the first trading day in such Offering Period; or (b) 85% of the Fair Market Value of such share on the last trading day in such Offering Period. 
 ATHEROS COMMUNICATIONS, INC. 
 2004 EMPLOYEE STOCK PURCHASE PLAN 
  

 -5- 

 (ii) The Purchase Price for each share of Stock purchased at the close of an Offering
Period (as previously defined under the Plan prior to this amendment and restatement of the Plan) beginning before May 5, 2006, shall be the lower of: (a) 85% of the Fair Market Value of such share on the first trading day in such Offering
Period; or (b) 85% of the Fair Market Value of such share on the last trading day of such Offering Period. 
 (c) Number of Shares
Purchased. As of the last day of each Offering Period, each Participant shall be deemed to have elected to purchase the number of shares of Stock calculated in accordance with this Subsection (c), unless the Participant has previously elected to
withdraw from the Plan in accordance with Section 6(a). The amount then in the Participant’s Plan Account shall be divided by the Purchase Price, and the number of shares that results shall be purchased from the Company with the funds in
the Participant’s Plan Account. The foregoing notwithstanding, no Participant shall purchase more than 1,875 shares of Stock with respect to any Offering Period commencing on or after May 5, 2006 (nor more than 1,875 shares of Stock with
respect to the six-month period ending May 4, 2006 for Offering Periods commencing prior to May 5, 2006), nor more than the amounts of Stock set forth in Section 9(b) and Section 14(a). Any fractional share, as calculated under
this Subsection (c), shall be rounded down to the next lower whole share. For each Offering Period, the Committee shall have the authority to establish additional limits on the number of shares purchasable by each Participant or by all Participants
in the aggregate. 
 (d) Available Shares Insufficient. In the event that the aggregate number of shares that all Participants elect
to purchase during an Offering Period exceeds the maximum number of shares remaining available for issuance under Section 14(a), then the number of shares to which each Participant is entitled shall be determined by multiplying the number of
shares available for issuance by a fraction, the numerator of which is the number of shares that such Participant has elected to purchase and the denominator of which is the number of shares that all Participants have elected to purchase.

 (e) Issuance of Stock. Certificates representing the shares of Stock purchased by a Participant under the Plan shall be issued to
him or her as soon as reasonably practicable after the close of the applicable Offering Period, except that the Committee may determine that such shares shall be held for each Participant’s benefit by a broker designated by the Committee
(unless the Participant has elected that certificates be issued to him or her). Shares may be registered in the name of the Participant or jointly in the name of the Participant and his or her spouse as joint tenants with right of survivorship or as
community property. 
 (f) Unused Cash Balances. An amount remaining in the Participant’s Plan Account that represents the
Purchase Price for any fractional share shall be carried over in the Participant’s Plan Account to the next Offering Period or refunded to the Participant in cash, without interest, if his or her participation is not continued. Any amount
remaining in the Participant’s Plan Account that represents the Purchase Price for whole shares that could not be purchased by reason of Subsection (c) above, Section 9(b) or Section 14(a) shall be refunded to the Participant in
cash, without interest.

 (g) Stockholder Approval. Any other provision of the Plan notwithstanding, no shares of Stock
shall be purchased under the Plan unless and until the Company’s stockholders have approved the adoption of the Plan. 
 SECTION 9 Limitations On Stock Ownership. 
 (a) Five Percent Limit. Any other provision of the Plan
notwithstanding, no Participant shall be granted a right to purchase Stock under the Plan if such Participant, immediately after his or her election to purchase such Stock, would own stock possessing 5% or more of the total combined voting power or
value of all classes of stock of the Company or any parent or Subsidiary of the Company. For purposes of this Subsection (a), the following rules shall apply: 
 (i) Ownership of stock shall be determined after applying the attribution rules of section 424(d) of the Code; 
 (ii) Each Participant shall be deemed to own any stock that he or she has a right or option to purchase under this or any other plan; and

 (iii) Each Participant shall be deemed to have the right to purchase up to the maximum number of shares of Stock that may
be purchased by a Participant under this Plan under the individual limit specified in Section 8(c). 
 (b) Dollar Limit. Any
other provision of the Plan notwithstanding, no Participant shall purchase Stock with a Fair Market Value in excess of the following limit: 
 (i) In the case of Stock purchased during an Offering Period that commenced in the current calendar year, the limit shall be equal to (A) $25,000 minus (B) the Fair Market Value of the Stock that the
Participant previously purchased in the current calendar year (under this Plan and all other employee stock purchase plans of the Company or any parent or Subsidiary of the Company). 
 (ii) In the case of Stock purchased during an Offering Period that commenced in the immediately preceding calendar year, the limit shall
be equal to (A) $50,000 minus (B) the Fair Market Value of the Stock that the Participant previously purchased (under this Plan and all other employee stock purchase plans of the Company or any parent or Subsidiary of the Company) in the
current calendar year and in the immediately preceding calendar year. 
 (iii) In the case of Stock purchased during an
Offering Period that commenced in the second preceding calendar year, the limit shall be equal to (A) $75,000 minus (B) the Fair Market Value of the Stock that the Participant previously purchased (under this Plan and all other employee
stock purchase plans of the Company or any parent or Subsidiary of the Company) in the current calendar year and in the two preceding calendar years.

 -7- 

 For purposes of this Subsection (b), the Fair Market Value of Stock shall be determined in each case as
of the beginning of the Offering Period in which such Stock is purchased. Employee stock purchase plans not described in section 423 of the Code shall be disregarded. If a Participant is precluded by this Subsection (b) from purchasing
additional Stock under the Plan, then his or her employee contributions shall automatically be discontinued and shall resume at the beginning of the earliest Offering Period ending in the next calendar year (if he or she then is an Eligible
Employee). 
 SECTION 10 Rights Not Transferable. 
 The rights of any Participant under the Plan, or any Participant’s interest in any Stock or moneys to which he or she may be entitled under the Plan,
shall not be transferable by voluntary or involuntary assignment or by operation of law, or in any other manner other than by beneficiary designation or the laws of descent and distribution. If a Participant in any manner attempts to transfer,
assign or otherwise encumber his or her rights or interest under the Plan, other than by beneficiary designation or the laws of descent and distribution, then such act shall be treated as an election by the Participant to withdraw from the Plan
under Section 6(a). 
 SECTION 11 No Rights As An Employee. 
 Nothing in the Plan or in any right granted under the Plan shall confer upon the Participant any right to continue in the employ of a Participating
Company for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Participating Companies or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her employment at
any time and for any reason, with or without cause. 
 SECTION 12 No Rights As A Stockholder. 
 A Participant shall have no rights as a stockholder with respect to any shares of Stock that he or she may have a right to purchase under the Plan until
such shares have been purchased on the last day of the applicable Offering Period. 
 SECTION 13 Securities
Law Requirements. 
 Shares of Stock shall not be issued under the Plan unless the issuance and delivery of such shares comply with (or
are 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 or other securities market on which the Company’s securities may then be traded. 
 SECTION 14
Stock Offered Under The Plan. 
 (a) Authorized Shares. The maximum aggregate number of shares of Stock available for purchase
under the Plan is 750,000 shares, plus an annual increase to be added on the first day of each fiscal year during the term of the Plan, beginning January 1, 2005, in an amount equal to the lesser of (i) 750,000 shares, (ii) 1.25% of
the outstanding shares of stock on the last day of the immediately preceding fiscal year, or (iii) an amount determined by the Board. The aggregate number of shares available for purchase under the Plan shall at all times be subject to
adjustment pursuant to Section 14.

 -8- 

 (b) Antidilution Adjustments. The aggregate number of shares of Stock offered under the Plan, the
individual Participant share limitation described in Section 8(c) and the price of shares that any Participant has elected to purchase shall be adjusted proportionately by the Committee for any increase or decrease in the number of outstanding
shares of Stock resulting from a subdivision or consolidation of shares or the payment of a stock dividend, any other increase or decrease in such shares effected without receipt or payment of consideration by the Company, the distribution of the
shares of a Subsidiary to the Company’s stockholders or a similar event. 
 (c) Reorganizations. Any other provision of the Plan
notwithstanding, immediately prior to the effective time of a Corporate Reorganization, the Offering Period then in progress shall terminate and shares shall be purchased pursuant to Section 8, unless the Plan is assumed by the surviving
corporation or its parent corporation pursuant to the plan of merger or consolidation. The Plan shall in no event be construed to restrict in any way the Company’s right to undertake a dissolution, liquidation, merger, consolidation or other
reorganization. 
 SECTION 15 Amendment Or Discontinuance. 
 The Board shall have the right to amend, suspend or terminate the Plan at any time and without notice. Unless earlier terminated by the Board, the Plan
shall terminate on January 13, 2014. Except as provided in Section 14, any increase in the aggregate number of shares of Stock to be issued under the Plan shall be subject to approval by a vote of the stockholders of the Company. In
addition, any other amendment of the Plan shall be subject to approval by a vote of the stockholders of the Company to the extent required by an applicable law or regulation. 
 SECTION 16 Execution. 
 To record the amendment and restatement of the Plan by the Board on April 19, 2006, the Company has caused its authorized officer to execute the same.

	 	(2)	the Company reduces your annual base salary or target incentive opportunity under the Company’s annual incentive plan, or reduces your target incentive opportunity under any

percentage corresponding to the Revenue levels set forth on the following Revenue Matrix: 

 FSL Performance Award Document
(RSUs) - 2006 
  

 -4- 

			
	 Revenue Levels
	 	 Percentage of Target Unit Earned

	 Threshold Revenue— $            
	 	75%
	 Target Revenue— $            -
	 	100%
	 Stretch 1 Revenue— $            
	 	133%
	 Stretch 2 Revenue— $            
	 	167%
	 Maximum Revenue— $            
	 	200%

  

	 	(B)	If Revenue is below the “Threshold Revenue” level, as set forth on the Revenue Matrix, you will not receive any Earned Units. If Revenue exceeds the “Maximum
Revenue,” as set forth on the Revenue Matrix, Earned Units will equal 200% of the Target Units. 

  

	 	(C)	If intermediate levels of Revenue are achieved between any of the Revenue Levels on the Revenue Matrix, the number of Earned Units will be calculated on a pro rata basis. For
example, if the number of Target Units is 1,000 and the Compensation Committee establishes a Threshold Revenue of $            , Target Revenue of
$            and the Revenue at the end of the Performance Period is $             billion, then the number of
Earned Units would be determined based upon a mathematical formula, as follows: 

  

			
	Revenue-Threshold =	 	X-Threshold Percentage
	Target-Threshold	 	Target Percentage- Threshold Percentage

  

			
	                    –                
    	 	= X-75
	                    –                
    	 	100-75

 X =          
         x 1,000 Target Units =
        Earned Units 
  

	 	(D)	Following the end of the Performance Period, the Compensation Committee will certify the Company’s Revenue and will determine the number of Earned Units based on the Revenue
Matrix and the terms of this Award Document. 

  

	8.	Adjustments. If the number of outstanding shares of Freescale Class A Common Stock (“Common Stock”) is changed as a result of stock dividend, stock
split or the like without additional consideration to the Company, the number of Units subject to this Award Document will be adjusted to correspond to the change in the outstanding shares of Common Stock. 

  

	9.	Delivery of Certificates or Equivalent. Upon the lapse of Restrictions applicable to the Units upon a Vesting Date or Vesting Event, the Company will:

  

	 	(A)	at its election, either deliver to you (or your executor or administrator) a certificate representing a number of shares of Common Stock equal to the number of Units upon which such
Restrictions have lapsed, or establish a brokerage account for you (or your executor or administrator) and credit to that account the number of shares of Common Stock of the Company equal to the number of Units upon which such Restrictions have
lapsed, and 

 FSL Performance Award Document (RSUs) - 2006 
  

 -5- 

	 	(B)	in either case, make a cash payment to you (or your executor or administrator) equal to the value of any fractional Unit then credited to your account; provided,
however, that in no event will the Company’s payment of the shares of Common Stock or any cash payment to you pursuant to 9(A) or 9(B) occur after two and a half months from the end of the Company’s fiscal year in which the
applicable Vesting Date or Vesting Event occurs. 

  

	10.	Withholding Taxes. 

  

	 	(A)	The Company is entitled to withhold an amount equal to Freescale’s required minimum statutory withholdings taxes for the respective tax jurisdiction attributable to any share
of Common Stock or property deliverable in connection with the Units. Unless you request otherwise in writing and that request is approved by the Company in accordance with its policies, the Company will satisfy the withholding obligation by
retaining shares of Common Stock deliverable in connection with the Units having a Fair Market Value on the date the Restrictions applicable to the Units lapse equal to the minimum amount required to be withheld. 

  

	 	(B)	For the purposes of this Award Document, “Fair Market Value” means the closing price for a share of Common Stock on the last trading day before the date the
Restrictions applicable to the Units lapse as reported for the New York Stock Exchange – Composite Transactions in the Wall Street Journal. 

  

	11.	Voting and Other Rights. 

  

	 	(A)	You have no rights as a stockholder of the Company in respect of the Units, including the right to vote and to receive dividends and other distributions, until delivery of
certificates representing, or other crediting to you of, shares of Common Stock in satisfaction of the Units. 

  

	 	(B)	The grant of Units does not confer upon you any right to continue in the employ of the Company or a Subsidiary or to interfere with the right of the Company or a Subsidiary, to
terminate your employment at any time. 

  

	 	(C)	The Plan is discretionary in nature and limited in duration, and may be amended, cancelled, or terminated by Freescale or a Subsidiary, in its sole discretion, at any time in
accordance with the terms of the Plan. The grant of awards under the Plan is a one-time benefit and does not create any contractual or other right to receive an award in the future. Future grants, if any, will be at the sole discretion of Freescale,
including, but not limited to, the timing of any grant, the amount of the award and vesting provisions. 

  

	12.	Funding. No assets or shares of Common Stock will be segregated or earmarked by the Company in respect of any Units awarded hereunder. The grant of Units hereunder does not
constitute a trust and is solely for the purpose of recording an unsecured contractual obligation of the Company. 

  

	13.	Compliance with Section 409A of the Internal Revenue Code. To the extent applicable, it is intended that this Award Document and the Plan comply with the provisions of
Section 409A of

 -6- 

 the Internal Revenue Code of 1986, as amended (the “Code”). This Award Document and the
Plan will be administered in a manner consistent with this intent, and any provision that would cause the Award Document or the Plan to fail to satisfy Section 409A of the Code will have no force and effect until amended to comply with
Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without your consent). In particular, to the extent Section 409A of the Code is
applicable, your right to the Units becomes non-forfeitable pursuant to Sections 4 or 5 and the event causing your right to become non-forfeitable is an event that does not constitute a permitted distribution event under Section 409A(a)(2) of
the Code, then notwithstanding anything to the contrary in Section 9 above, delivery under Section 9 will not be made until the earliest of (a) your “separation from service” with the Company (determined in accordance with
Section 409A); provided, however, that in the case where you are a “specified employee” (within the meaning of Section 409A), the date of delivery will be made on the date which is six months after the date of
separation from service with the Company; (b) the date payment would otherwise occur under this Award Document (to the extent it constitutes a permitted distribution event) or (c) your death. References to Section 409A of the Code
will also include any proposed, temporary or final regulations, or any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.
