WARRANT TO PURCHASE COMMON STOCK

THIS CERTIFIES THAT, for the purchase price of $                 paid and received,                                     (the “Purchaser”) is entitled to subscribe for and purchase from NetLogic Microsystems, Inc., a Delaware corporation (the “Company”), up to                              fully paid and nonassessable shares (the “Warrant Shares”) of Common Stock, $0.001 par value per share, of the Company (“Common Stock”) at an exercise price equal to $0.50 per share (the “Exercise Price”), subject to the provisions and upon the terms and conditions hereinafter set forth.

1. Method of Exercise; Payment.

(a) Exercise Period. The purchase rights represented by this Warrant may be exercised by the Purchaser during the term of this Warrant (as set forth in Section 10), in whole or in part, at any time after the Commencement Date (as defined in Section 10), by the surrender of this Warrant (with the notice of exercise form (the “Notice of Exercise”) attached hereto as Attachment 1 duly executed) at the principal office of the Company.

(b) Cash Exercise. This Warrant may be exercised by the payment to the Company of an amount equal to the Exercise Price multiplied by the number of Warrant Shares being purchased, at the election of the Purchaser, by wire transfer or certified check payable to the order of the Company. The person or persons in whose name(s) any certificate(s) representing Warrant Shares shall be issuable upon exercise of this Warrant shall be deemed to have become the holder(s) of record of, and shall be treated for all purposes as the record holder(s) of, the Warrant Shares represented thereby (and such Warrant Shares shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is exercised.

(c) Net Issue Exercise. In lieu of exercising this Warrant pursuant to Section 1(b) above, the Purchaser may elect to receive a number of Warrant Shares equal to the value (as determined below) of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with Notice of Exercise indicating the

1

method of exercise. In such event, the Company shall issue to the Purchaser that number of Warrant Shares computed using the following formula:

Where X = the number of Warrant Shares to be issued to the Purchaser;

    Y = the number of Warrant Shares subject to the Warrant (or the portion thereof being canceled);

    A = the fair market value of one Warrant Share (at the date of such calculation); and

    B = the Exercise Price (as adjusted to the date of such calculation).

(d) Fair Market Value. For purposes of this Section 1, the fair market value of one Warrant Share shall mean:

(i) The closing price for the Common Stock as reported on the NASDAQ Stock Market (or on any national securities exchange or other established market on which the Common Stock is then listed) for that date or, if no closing price is reported for that date, the closing price on the next preceding date for which a closing price was reported; or

(ii) If the Common Stock is not traded on the NASDAQ Stock Market (or on any national securities exchange or other established market), fair market value of a Warrant Share shall be agreed to by the parties hereto. If the parties cannot agree on the fair market value within five business days of delivery of the Notice of Exercise, the Board of Directors of the Company (the “Board”) shall determine in good faith the fair market value of a Warrant Share; provided, however, that the fair market value of a Warrant Share shall be no lower than the price at which the Company last sold its Common Stock or the exercise price of its last granted options, whichever occurs later. Receipt and formal acknowledgment by a duly authorized representative of the Purchaser of the Warrant Shares issued upon exercise of this Warrant by the Purchaser shall be conclusively deemed to be an acknowledgment and acceptance of any such fair market value determination by the Board as the final and binding determination of such value for purposes of this Warrant.

(e) Stock Certificates. In the event of any exercise of the rights represented by this Warrant, certificates for the Warrant Shares so purchased shall be delivered to the Purchaser within a reasonable time and, unless this Warrant has been fully exercised or has expired, a new Warrant representing the shares with respect to which this Warrant shall not have been exercised shall also be issued to the Purchaser within such time.

2. Stock Fully Paid; Reservation of Shares. All of the Warrant Shares issuable upon the exercise of the rights represented by this Warrant will, upon issuance and receipt of the aggregate Exercise Price therefor, be fully paid and nonassessable, and free from all preemptive rights, rights of first refusal or first offer, taxes, liens and charges with respect to the issuance thereof. During the period within which the rights represented by this Warrant may be exercised, the Company shall at all times have authorized and reserved for issuance sufficient shares of Common Stock to provide for the exercise of the rights represented by this Warrant.

3. Adjustment of Exercise Price and Number of Shares. Subject to the provisions of Section 10, the number and kind of Warrant Shares purchasable upon the exercise of this Warrant

2

and the Exercise Price therefor shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a) Reclassification. In case of any reclassification or capital reorganization of the Warrant Shares (other than a change in par value, or as a result of a subdivision or combination), the Company shall execute a new warrant, providing that the holder of this Warrant shall have the right to exercise such new warrant, and procure upon such exercise and payment of the same aggregate Exercise Price, in lieu of the Warrant Shares theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property as would be payable for the Warrant Shares issuable upon exercise of this Warrant as if such Warrant Shares were outstanding immediately prior to such reclassification or reorganization.

(b) Stock Splits, Dividends and Combinations. In the event that the Company shall at any time subdivide the outstanding shares of Warrant Shares, or shall issue a stock dividend on its outstanding shares of Warrant Shares, the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such subdivision or to the issuance of such stock dividend shall be proportionately increased, and the Exercise Price shall be proportionately decreased, and in the event that the Company shall at any time combine the outstanding shares of Warrant Shares, the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such combination shall be proportionately decreased, and the Exercise Price shall be proportionately increased, effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be.

4. Notices.

(a) Upon any adjustment of the Exercise Price and any increase or decrease in the number of Warrant Shares purchasable upon the exercise of this Warrant in accordance with Section 3, then, and in each such case, the Company, within 30 days thereafter, shall give written notice thereof to the Purchaser at the address of such Purchaser as shown on the books of the Company, which notice shall be signed by the Company’s Chief Financial Officer and state the Exercise Price as adjusted and, if applicable, the increased or decreased number of Warrant Shares purchasable upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation of each and the factors upon which such calculations are based.

(b) Any notice, demand, request or communication hereunder to any party shall be deemed to be sufficient if contained in a written instrument delivered in person or duly sent by first class registered, certified or overnight mail, postage prepaid, or facsimile or electronic transmission (with a confirmation copy by regular, certified or overnight mail), addressed or sent, as the case may be, (i) if to a Purchaser, to such Purchaser’s residence address, facsimile number or electronic mail address last filed with the Company and (ii) if to the Company, to 450 National Avenue, Mountain View, CA 94043, Attention: Mr. Ronald Jankov, Facsimile: (650) 961-1092, ***@***, or such other address as the Company shall have furnished to such Purchaser in writing.

3

consented to receive notice, provided, that such consent is deemed revoked if the sender is unable to deliver by electronic transmission two consecutive notices and such inability becomes known to the Company.

5. Other Notices. If at any time:

(a) the Company shall declare any cash dividend upon its Common Stock;

(b) the Company shall declare any dividend upon its Common Stock payable in stock or make any special dividend or other distribution to the holders of its Common Stock;

Any notice given in accordance with the foregoing sentence shall also specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Warrant Shares shall be entitled thereto.

This Warrant may only be transferred in compliance with federal and state securities laws and, except as provided below, may not be transferred except with the prior written consent of the Company, which shall not be unreasonably withheld or delayed, and any purported transfer without such prior written consent shall be null and void; provided, however, that the Company may withhold its consent to the transfer or assignment of this Warrant to any person or entity who is deemed to be a competitor or prospective competitor of the Company, such determination to be made in the reasonable judgment of the Board. Notwithstanding the foregoing, Purchaser may freely transfer this Warrant or portion thereof to (i) subsidiaries, affiliates, members
