THIS CERTIFIES THAT, for value received, (the “Holder”) is entitled to subscribe for a purchase from Turin Networks, Inc., a Delaware Corporation (the “Company”), fully paid and nonassessable shares (as adjusted pursuant to Section 2 hereof) (the “Warrant Shares”) of Series A-1 Preferred Stock of the Company (“Series A-1 Preferred Stock”) at the purchase price of $ per share (as adjusted pursuant to Section 2 hereof) (the “Exercise Price”), upon the terms and subject to the conditions hereinafter set forth:

1. EXERCISE RIGHTS.

(a) Cash Exercise. The purchase rights represented by this Warrant may be exercised by the Holder at any time and from time to time during the term hereof, in whole or in part, by delivery to the principal offices of the Company of this Warrant and a completed and duly executed Notice of Cash Exercise, in the form attached as Exhibit “A” hereto, accompanied by payment to the Company of an amount equal to the Exercise Price then in effect multiplied by the number of Warrant Shares to be purchased by the Holder in connection with such cash exercise of this Warrant, which amount may be paid, at the election of the Holder, by wire transfer to an account designated by the Company or delivery of a certified check payable to the order of the Company.

(b) Net Issue Exercise.

(i) In lieu of exercising the purchase rights represented by this Warrant on a cash basis pursuant to Section 1(a) hereof, the Holder may elect to exercise such rights represented by this Warrant at any time and from time to time during the term hereof, in whole or in part, on a net-issue basis (the “Net Exercise Right”) by electing to receive the number of Warrant Shares which are equal

in value to the value of this Warrant (or any portion thereof to be canceled in connection with such Net Exercise Right) at the time of any such exercise of the Net Exercise Right, by delivery to the principal offices of the Company of this Warrant and a completed and duly executed Notice of Net-Issue Exercise, in the form attached as Exhibit “B” hereto, properly marked to indicate (A) the number of Warrant Shares to be delivered to the Holder in connection with such exercise of the Net Exercise Right, (B) the number of Warrant Shares with respect to which the Warrant is being surrendered in payment of the aggregate Exercise Price for the Warrant Shares to be delivered to the Holder in connection with such net-issue exercise, and (C) the number of Warrant Shares which remain subject to the Warrant after such exercise of the Net Exercise Right, if any (each as determined in accordance with Section1(b)(ii) hereof).

(ii) In the event that the Holder shall elect to exercise the rights represented by this Warrant in whole or in part pursuant to the Net Exercise Rights Provided in this Section 1(b), the Company shall issue to the Holder the number of Warrant Shares determined in accordance with the following formula:

X = Y(A-B)

X = the number of Warrant Shares to be issued to the Holder in connection with such Net Exercise Right.

Y = the number of Warrant Shares subject to this Warrant and surrendered pursuant to the Net Exercise Right.

A = the Fair Market Value of one share of Series A-1 Preferred Stock or (if all shares of Series A-1 Preferred Stock have been converted into Common Stock or if this Warrant is being exercised in connection with the Company’s IPO (as hereinafter defined)) Common Stock.

B = the Exercise Price in effect as of the date of exercise of the Net Exercise Right (as adjusted pursuant to Section 2 hereof.)

(c) Fair Market Value. For purposes of this Section 1, the “Fair Market Value” of the Series A-1 Preferred Stock or Common Stock shall have the following meanings:

(i) If the Company’s Series A-1 Preferred Stock or its Common Stock is not listed for trading on a national securities exchange or admitted for trading on a national market system, then the Fair Market Value of the Series A-1 Preferred Stock or Common Stock shall be deemed to be the fair market value of Series A-1 Preferred Stock or Common Stock as determined in good faith and in the sole discretion of the Board of Directors of the Company (the “Board of Directors”) from time to time, and receipt and acknowledgment of this Warrant by the Holder shall be deemed to be an acknowledgment and acceptance of any such determination of the fair market value of Series A-1 Preferred Stock or Common Stock, as applicable, by the Board of Directors as the final and binding determination of such fair market value of purposes of this Warrant.

(ii) If the Company’s Series A-1 Preferred Stock or its Common Stock is listed for trading on a national securities exchange or admitted for trading on a national market system, then the per share Fair Market Value of the Series A-1 Preferred or Common Stock shall be deemed to be the closing price quoted on the NASDAQ National Market exchange on which the Company’s Series A-1 Preferred or Common Stock is listed for trading, or if not so listed, the average of the closing bid and asked prices for the Company’s Series A-1 Preferred or Common Stock quoted on the Over-the-Counter Summary, each as published in the Western Edition of The Wall Street Journal, for the ten (10) trading days prior to the date of determination of Fair Market Value in accordance herewith.

(iii) If the Net Exercise Right provided for in Section 1(b) is exercised in connection with and contingent upon the Company’s initial public offering pursuant to a firm commitment underwriting and a registration statement filed under the Securities Act of 1933, as amended, covering the offer and sale of the Company’s Common Stock for the account of the Company (the “IPO”), and if the Company’s registration statement relating to such offering has been declared effective by the Securities and Exchange Commission (the “SEC”), then the initial “Price to the Public” as specified in the final prospectus shall be deemed the “Fair Market Value” of such Common Stock.

(d) Additional Conditions to Exercise of Warrant. Unless there is a registration statement declared or ordered effective by the Securities and Exchange Commission (the “Commission”) under the Securities Act which includes the Warrant Shares to be issued upon the exercise of the rights represented by this Warrant, such rights may not be exercised unless and until:

(ii) each certificate evidencing the Warrant Shares to be issued upon the exercise of the rights represented by this Warrant shall be stamped or imprinted with a legend substantially in the following form:

SUCH SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE DISTRIBUTED EXCEPT (i) PURSUANT TO A REGISTRATION STATEMENT DECLARED OR ORDERED EFFECTIVE BY THE SECURITIES AND EXCHANGE COMMISSION UNDER THE SECURITIES ACT COVERING SUCH SECURITIES, OR (ii) IN COMPLIANCE WITH RULE 144, OR

(iii) PURSUANT TO AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF SUCH SECURITIES THAT SUCH REGISTRATION OR RULE 144 COMPLIANCE IS NOT REQUIRED UNDER THE SECURITIES ACT AS TO SUCH SALE, OFFER OF SALE, PLEDGE, HYPOTHECATION OR OTHER DISTRIBUTION. THIS CERTIFICATE MUST BE SURRENDERED TO THE ISSUER HEREOF OR ITS TRANSFER AGENT AS A CONDITION PRECEDENT TO THE TRANSFER OF ANY INTEREST IN THE SECURITIES REPRESENTED HEREBY.

(e) Fractional Shares. Upon the exercise of the rights represented by this Warrant, the Company shall not be obligated to issue fractional shares of Series A-1 Preferred Stock or Common Stock, as applicable, and in lieu thereof, the Company shall pay to the Holder an amount in cash equal to the Fair Market Value per share of such Series A-1 Preferred Stock or Common Stock, as applicable, immediately prior to such exercise multiplied by such fraction (rounded to the nearest cent).

(f) Record Ownership of Warrant Shares. The Warrant Shares shall be deemed to have been issued, and the person in whose name any certificate representing Warrant Shares shall be issuable upon the exercise of the rights represented by this Warrant (as indicated in the appropriate Notice of Exercise) shall be deemed to have become the holder of record of (and shall be treated for all purposes as the record holder of) the Warrant Shares represented thereby, immediately prior to the close of business on the date or dates upon which the rights represented by this Warrant are exercised in accordance with the terms hereof.

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

(h) Issue Taxes. The issuance of certificates for shares of Series A-1 Preferred Stock upon the exercise of the rights represented by this Warrant shall be made without charge to the Holder for any issuance tax in respect thereof, provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of the Holder of the Warrant, and no such issuance or delivery shall be made unless and until the person requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

2. ADJUSTMENT RIGHTS.

(a) Right to Adjustment. The number of Warrant Shares purchasable upon the exercise of the rights represented by this Warrant, and the Exercise Price therefor, shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(i) Reclassifications. In the event of a reclassification of the Series A-1 Preferred Stock other than a change in par value or from par value to no par value, by stock split, stock dividend, subdivision, reverse stock split, consolidation or combination thereof as provided by subsection (ii) below, the Company shall execute a new Warrant, the terms of which provide that the holder of this Warrant shall have the right to exercise the rights represented by such new Warrant, and procure upon such exercise and payment of the same aggregate Exercise Price then in effect, in lieu of the shares of Series A-1 Preferred Stock theretofore issuable upon exercise of the rights represented by this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such reclassification by a holder of an equivalent number of shares of Series A-1 Preferred Stock. Such new Warrant shall provide for adjustments, which are as equivalent as practicable to the adjustments provided for in this Section 2. Notwithstanding the foregoing, no adjustment of this Warrant or Issuance of any new warrant shall be required to the extent the number of Warrant Shares and Exercise Price of this Warrant have already been adjusted pursuant to any other subsection of this Section 2(a). The provisions of this Section 2(a)(i) shall apply with equal force and effect to all successive reclassifications of the Series A-1 Preferred Stock.

(ii) Stock Splits, Dividends, Combinations and Consolidations. In the event of a stock split, stock dividend or subdivision of or in respect of the outstanding shares of Series A-1 Preferred Stock, the number of Warrant Shares issuable upon the exercise of the rights represented by this warrant immediately prior to such stock split, stock dividend or subdivision shall be proportionately increased and the Exercise Price then in effect shall be proportionately decreased, effective at the close of business on the date of such stock split, stock dividend or subdivision, as the case may be. In the event of a reverse stock split, consolidation, combination or other similar event of or in respect of the outstanding shares of Series A-1 Preferred Stock, the number of Warrant Shares issuable upon the exercise of the rights represented by this Warrant immediately prior to such reverse stock split, consolidation, combination or other similar event shall be proportionately decreased and the Exercise Price shall be proportionately increased, effective at the close of business on the date of such reverse stock split, consolidation, combination or other similar event, as the case may be. Notwithstanding the foregoing, no adjustment of this Warrant shall be required to the extent the number of Warrant Shares and Exercise Price of this Warrant have already been adjusted pursuant to any other subsection of this Section 2(a). The provisions of this Section 2(a)(ii) shall apply with equal force and effect to all successive stock splits, stock dividends, subdivisions, reverse stock splits, consolidations, combinations or other similar events of the Series A-1 Preferred Stock.

(iii) Mergers and Consolidations; Sales of Assets or Stock. In the event of (1) a merger or consolidation of the Company with or into another corporation, limited liability company, general or limited partnership, joint venture, association or other legal entity (other than a merger or consolidation pursuant to which the Company is the surviving corporation and the stockholders of the Company immediately preceding such merger or consolidation continue to own at least fifty percent (50%) of the capital stock of the Company entitled to vote following the closing of such merger or consolidation and which does not result in any reclassification of the Warrant Shares issuable upon the exercise of the rights represented by this Warrant), or (2) the sale of all or substantially all of the assets or capital stock of the Company, the Company, or any successor corporation or other legal entity, as the case may be, shall execute a new Warrant, the terms of which provide that the holder of this Warrant shall have the right to exercise the rights

represented by such new Warrant, and procure upon such exercise and payment of the same aggregate Exercise Price then in effect, in lieu of the shares of Series A-1 Preferred Stock theretofore issuable upon exercise of the rights represented by this Warrant, the kind and amount of shares of stock, other securities, money and property receivable upon such merger, consolidation or sale of assets or capital stock by a holder of an equivalent number of shares of Series A-1 Preferred Stock. Such new Warrant shall provide for adjustments, which are as equivalent as practicable to the adjustments provided for In this Section 2. Notwithstanding the foregoing, no adjustment of this Warrant or issuance of any new warrant shall be required to the extent the number of Warrant Shares and Exercise Price of this Warrant have already been adjusted pursuant to any other subsection of this Section 2(a). The provisions of this Section 2(a)(iii) shall apply with equal force and effect to all successive mergers, consolidations and sales of assets and capital stock of the Series A-1 Preferred Stock.

(b) Adjustment Notices. Upon any adjustment of the Exercise Price, and any increase or decrease in the number of warrant shares subject to this Warrant, in accordance with this Section 2, the Company, within sixty (60) days thereafter, shall give written notice thereof to the Holder at the address of such Holder as shown on the books of the Company, which notice shall state the Exercise Price as adjusted and, if applicable, the increased or decreased number of Warrant Shares subject to this Warrant, setting forth in reasonable detail the method of calculation of each such adjustment.

(c) Conversion of Series A-1 Preferred Stock. In the event that all shares of Series A-1 Preferred Stock have converted into Common Stock and no shares of Series A-1 Preferred Stock are then outstanding, this Warrant shall thereafter (subject to the termination provisions contained in Section 8) entitle the Holder to purchase such number of shares of the Company’s Common Stock (the “Issuable Common Stock”) equal to the number of Warrant Shares remaining issuable upon exercise of this Warrant multiplied by the number of shares of Common Stock into which one share of the Company’s Series A-1 Preferred Stock was convertible as determined by the last such conversion to occur for the last share of Series A-1 Preferred previously outstanding. The Exercise Price then in effect shall be adjusted to equal the Exercise Price immediately prior to the conversion of the last share of Series A-1 Preferred Stock multiplied by a fraction, the numerator of which equals the number of Warrant Shares remaining issuable upon exercise of this Warrant and the denominator of which equals the number of shares of Common Stock issuable pursuant to this Warrant immediately after the last such conversion to occur for the last share of Series A-1 Preferred previously outstanding.

3. TRANSFER OF WARRANT.

SELLER:		Turin Networks, inc.

COMPANY:		Turin Networks, Inc.

SECURITY:		Series A-1 Preferred Stock or Common Stock, as applicable, issued Upon The Exercise Of Warrant No Issued On .

AMOUNT:		SHARES

DATE:

The undersigned hereby represent and warrants to Turin Networks, Inc., a Delaware corporation (the “Company”), as follows:

1. I am aware of the business affairs, financial condition and results of operations of the Company and have acquired sufficient information about the Company to reach an informed and knowledgeable investment decision to acquire the Securities. I am purchasing the Securities for my own account for investment purposes only and not with a view to, or for the resale in connection with, any “distribution” thereof for purposes of the Securities Act of 1933, as amended (the “Securities Act”).

2. I understand that the Securities have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of my investment intent as expressed herein. I understand that, in the view of the Securities and Exchange Commission (the “Commission”), the statutory basis for such exemption may be unavailable if my representation was predicated solely upon a present intention to hold the Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one year Or any other fixed period in the future.

3. I further understand that the Securities must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from registration is otherwise available. In addition, I understand that the certificate evidencing the Securities will be imprinted with a legend, which prohibits the transfer of the Securities unless they are registered or such registration is not required in the opinion of counsel for the Company.

4. I am familiar with the provisions of Rule 144, promulgated under the Securities Act, which, in substance, permits limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions.

5. I further understand that in the event all of the applicable requirements of Rule 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rule 144 is not exclusive, the Staff of the Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.
