representations or warranties by the indemnifying Party; or (ii) intentional misconduct or gross negligence by the indemnifying Party or its employees or agents in the course of performing under this Agreement.

(i) the indemnified Party promptly notifying the indemnifying Party in writing within a reasonable period of time of any and all claims for which the indemnified Party is entitled to indemnification, provided, however, that any failure
on the part of such indemnified Party to so notify the indemnifying Party shall not limit any of the indemnified Partys rights to indemnification under this Section 8 except to the extent such failure materially prejudices the defense of
such claim, (ii) giving the indemnifying Party sole control of the defense thereof and any related settlement negotiations, provided, however, that if an indemnified Party reasonably determines that a conflict of interest exists in
respect of such claim, such indemnified Party will have the right to employ separate counsel to represent such indemnified Party and in that event the reasonable fees and expenses of such separate counsel (but not more than one separate counsel and

not include a full general release of all the claims against all of such partys Indemnified Parties contemplated by the demand, claim or suit from all other parties to such matter or that requires such Party or any of its Affiliates to perform
any covenant or refrain from engaging in any activity.

9.4 Effects of Termination.

9.4.1 Upon termination of this Agreement for any reason or earlier as requested by AMCC, Company will deliver to AMCC any and all
documents, prototypes, samples, and other materials (including all copies thereof) in Companys possession or control that contain, summarize, or disclose any Work Product (in whatever stage of development or completion) or any AMCC Technology
provided by or on behalf of AMCC to Company.

9.4.2In the event of the Companys written allegation, made to AMCC
in good faith, that (Y) AMCC is in material breach of its obligations under this Agreement and failed to timely cure such breach within the time period(s) provided herein, or (Z) AMCC has failed to acquire the Company in breach of
AMCCs obligation under the Merger Agreement (either event, a Good Faith Allegation of Breach): (i) during the first ten (10) Calendar Quarters in the Quarterly Payment Period, AMCC shall
continue to make the Quarterly Payments in accordance with the schedule in Section 3.3 hereof for up to the two (2) Calendar Quarters immediately following the Calendar Quarter in which the Good Faith Allegation of Breach occurs;
(ii) in the eleventh (11th) Calendar Quarter in the Quarterly Payment Period, AMCC shall continue to make the Quarterly Payment in accordance with the schedule in Section 3.3 hereof for up to the last Calendar Quarter in the Quarterly
Payment Period and shall make a payment of up to $1.5 Million to Company for the first Calendar Quarter immediately following the Quarterly Payment Period within ten (10) days after the beginning of such Calendar Quarter; and (iii) in the
twelfth (12th) Calendar Quarter in the Quarterly Payment Period, AMCC shall make a payment of up to $1.5 Million to Company for each of the two (2) Calendar Quarters immediately following the Quarterly Payment Period within ten
(10) days after the beginning of each such Calendar Quarter (the last day of such period in which AMCC is required to make a payment to Company pursuant to this sentence, the Resolution Deadline); provided that,
notwithstanding the foregoing, AMCC shall not be required to make any payment to Company pursuant to this sentence at or after it is finally determined pursuant to the terms hereof that AMCC did not commit the material breach alleged by Company in
the Good Faith Allegation of Breach. Provided that Company has acted in good faith and in full compliance with the procedures for resolution set forth herein, in the event the matter subject to the Good Faith Allegation of Breach has not been
finally resolved pursuant to the procedures set forth in Section 9.4.4 by the Resolution Deadline solely as a result of the request by the arbitrator or other body selected by the parties to finally determine such matter, AMCC shall pay
Company an amount of up to $1.5 Million for the Calendar Quarter immediately following the Resolution Deadline, which payment shall be pro rated to equal (X) $1.5 Million multiplied by (Y) (I) the number of days elapsed between the
Resolution Deadline and the date it is finally determined pursuant to the terms hereof whether AMCC committed the material breach alleged by Company in the Good Faith Allegation of Breach (the Resolution Date) or, if the
Resolution Date does not occur within such Calendar Quarter, ninety-one (91), divided by (II) ninety-one (91), which shall be payable on the Resolution Date or the end of such Calendar Quarter, as applicable. Notwithstanding anything herein to the
contrary, AMCC shall not be required to make any payments to Company pursuant to Section 3.3 or this Section 9.4.2 unless during the full Calendar Quarter for which Company receives or is entitled to receive payment from AMCC, Company
performs its obligations under this Agreement. In the event Company fails to perform its obligations under this Agreement during any such Calendar Quarter, Company shall promptly return the payment made by AMCC corresponding to such Calendar Quarter
to AMCC in full.

9.4.3In the event it is finally determined in accordance with the procedures set
forth in Section 9.4.4 (the date of such final determination, the Determination Date) that AMCC committed a material breach of its obligations under this Agreement pursuant to Section 9.3 (a Breach),
AMCC shall, within ten (10) days following the Determination Date, pay Company $5 Million (the Breach Payment) and the Work Product License shall become effective; provided that such Breach Payment and Work Product

by AMCC in order to comply with a remedy of specific performance (as reasonably determined by AMCC), for such Breach (the Final Award) exceeds the amount of the Breach Payment, such Final Award shall be reduced by the full amount
of the Breach Payment. In the event that such Final Award is less than the amount of the Breach Payment, Company shall either (I) pay AMCC the amount equal to the Breach Payment less the Final Award within fifteen (15) days following the
date of determination of the Final Award, or (II) grant AMCC a non-exclusive, perpetual, worldwide, fully paid, royalty-free license under all of Companys Intellectual Property Rights in all Technologies, in any stage of development, that

Technologies, in each case developed on or after the Determination Date.

under this Agreement or (ii) AMCC has failed to acquire the Company in breach of AMCCs obligations under the Merger Agreement. Such arbitration shall be conducted pursuant to an arbitration procedure under which the Parties shall jointly
select within fifteen (15) days of the Demand (as defined below) an independent arbitrator with the relevant industry and technical background but with no prior, existing or potential business relationship with either Party or an entity
controlled by, controlling or under common control with either Party. If for whatever reason the Parties cannot mutually agree on an independent arbitrator within fifteen (15) days, Judicial Arbitration Mediation Services shall appoint an
arbitrator it deems to have reasonable relevant industry and technical background. The location of such arbitration shall be in the County of Santa Clara, California or as otherwise mutually agreed upon by the Parties. Upon the request of either
Party, the arbitrator will hear each Partys presentation within forty-five (45) days of such selection. The arbitrator will rule within thirty (30) days following the conclusion of such presentation by the Parties.

(b)Such arbitration shall be conducted according to the Commercial Arbitration Rules of the American Arbitration Association, as
such rules shall be in effect on the date of delivery of a written demand for arbitration (Demand), except to the extent that such rules are inconsistent with the provisions set forth in this Agreement.

jurisdiction. The Parties agree that the existence, conduct and content of any arbitration shall be kept confidential and no Party shall disclose to any person any information about such arbitration, except as may be required by law, including but

arbitration provision or any award hereunder or to obtain interim relief.

(d)Each Party shall pay the fees of its
own attorneys, expenses of witnesses and all other expenses and costs in connection with the presentation of such Partys case. The remaining costs of the arbitration, including without limitation, fees of the arbitrator, costs of records or
transcripts and administrative fees shall be borne equally by the Parties.

(e)The arbitrators role shall be
limited to determining whether (i) AMCC is in material breach of its obligations under this Agreement or (ii) AMCC has failed to acquire the Company in breach of AMCCs obligations under the Merger Agreement.

(f) Notwithstanding the dispute resolution procedure set forth in this Section, any Party may apply to a court as set forth in

Exercise; and

(2) With respect to Warrant Shares that are unvested upon such issuance by the Company, a certificate
for shares purchased hereunder shall be transmitted by the transfer agent of the Company to the Company, as escrow agent, to hold such unvested Warrant Shares in escrow pursuant to the terms and conditions of that certain Escrow Agreement, dated

Escrow, such Warrant Shares shall be immediately released from the Escrow to Veloce.

(b) As of the end of the
Termination Date, in the event any unvested Warrant Shares are held in Escrow, (i) all such unvested Warrant Shares shall be deemed immediately repurchased from Veloce by the Company and released to the Company from the Escrow, at which time
such Warrant Shares may be cancelled, terminated or held as treasury stock, in the Companys sole discretion, and (ii) the Company shall pay Veloce by cash or check an amount equal to the Exercise Price paid by Veloce (or, if exercised
pursuant to a cashless exercise, a repurchase price of $0.01 per share) for the Warrant Shares deemed repurchased under clause (i) hereof.

4. Reservation of Stock. The Company covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the Company will at all times have
authorized, and in reserve, a sufficient number of shares of its Common Stock to provide for the exercise of the rights represented by this Warrant.



| | 5. | Compliance with Securities Act.
| | -- | -------------------------------

(a) Veloce, by acceptance of this Warrant, agrees that this Warrant and the Warrant Shares to be issued upon exercise hereof are being acquired for investment for its own account and that Veloce
will not offer, sell or otherwise transfer any Warrant Shares to be issued upon exercise hereof, in whole or in part, except under circumstances that will not result in a violation of the Securities Act of 1933, as amended (the
Securities Act), or any state securities laws. The Warrant Shares shall be stamped or imprinted with legends in substantially the following forms:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE OFFERED, SOLD, ASSIGNED, PLEDGED, TRANSFERRED OR OTHERWISE
DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM REGISTRATION UNDER SAID ACT AND, IF REQUESTED BY THE COMPANY IN CONNECTION WITH SUCH A DISPOSITION PURSUANT TO AN
EXEMPTION.

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO FORFEITURE TO THE COMPANY PURSUANT TO
AN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER, OR SUCH HOLDERS PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE



4



---

PRINCIPAL OFFICE OF THIS COMPANY. ANY TRANSFER OR ATTEMPTED TRANSFER OF ANY SHARES SUBJECT
TO SUCH RISK OF FORFEITURE IS VOID WITHOUT THE PRIOR EXPRESS WRITTEN CONSENT OF THE COMPANY.

(b) By
acceptance of this Warrant, Veloce specifically represents and warrants to the Company as follows:

(i) Veloce
believes it has received all the information it considers necessary or appropriate for deciding whether to acquire this Warrant. Veloce further represents that it has had an opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the offering of the Warrant and the business, properties and financial condition of the Company.

(ii) Veloce understands that this Warrant is, and the Warrant Shares will be upon issuance, restricted securities
under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the
Securities Act only in certain limited circumstances. In addition, Veloce represents that it is familiar with Rule 144 promulgated under the Securities Act, and understands the resale limitations imposed thereby and by the Securities Act.

(iii) Veloce (a) is an accredited investor as defined in Regulation D under the Securities Act,
(b) can bear the economic risk of its investment in the Warrant and the Warrant Shares, and (c) has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in
the Warrant and the Warrant Shares.



| | 6. | Protection Against Dilution.
| | -- | ----------------------------

(a) Stock Dividends, Subdivisions and Combinations. In the event that after the initial date of issuance of this Warrant the Company shall:

(i) subdivide its outstanding shares of Common Stock into a larger number of shares of Common Stock or issue a stock dividend to
all the holders of Common Stock; or

(ii) combine its outstanding shares of Common Stock into a smaller number of
shares of Common Stock;

then (y) the Number of Warrant Shares shall be adjusted to that Number of Warrant Shares
determined by multiplying the Number of Warrant Shares that could be purchased hereunder immediately prior to such event by a fraction (A) the numerator of which shall be the total number of outstanding shares of Common Stock immediately after
such event and (B) the denominator of which shall be the total number of outstanding shares of Common Stock immediately prior to such event and (z) there shall be no adjustment to the Exercise Price.



5



---

(b) Notice of Adjustments. Whenever the Number of Warrant Shares purchasable
shall be required to be adjusted pursuant to Section 6(a) hereof, the Company shall prepare a certificate signed by the Secretary of the Company setting forth, in reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and shall provide a copy of such certificate to Veloce.

7. Notice of Extraordinary Dividends. If the Board of Directors of the Company shall declare any dividend or other
distribution on its Common Stock except out of earned surplus or by way of a stock dividend payable on its Common Stock, the Company shall mail notice thereof to Veloce not less than fifteen (15) days prior to the record date fixed for
determining stockholders entitled to participate in such dividend or other distribution and Veloce shall not participate in such dividend or other distribution or be entitled to any rights on account or as a result thereof unless and to the extent
the Warrant is exercised prior to such record date.

8. Fractional Shares. Fractional shares shall not be issued
upon the exercise of this Warrant but in any case where Veloce would, except for the provisions of this Section 8, be entitled under the terms hereof to receive a fractional share upon the complete exercise of this Warrant, the Company shall,
upon the exercise of this Warrant for the largest number of whole shares then called for, pay a sum in cash equal to the excess of the value of such fractional share (determined based on the closing price of the Common Stock, as reported on the
applicable market of the Nasdaq Stock Market, LLC, as of the trading day immediately prior to the date of such exercise) over the proportional part of the Exercise Price represented by such fractional share.

9. Fully Paid Stock; Authority; Taxes. The Company covenants and agrees that the shares of Common Stock issued upon
exercise of this Warrant in accordance with its terms shall, at the time of such delivery, be validly issued and outstanding and be fully paid and nonassessable. The Company represents and warrants that this Warrant has been duly authorized by all
necessary corporate action, has been duly executed and delivered and is a legal and binding obligation of the Company. Veloce covenants and agrees that it shall pay when due and payable any and all federal and state taxes (other than income taxes)
that may be payable in respect of this Warrant or any Common Stock or certificates therefor upon the exercise of this Warrant in accordance with its terms.

10. Restriction on Transferability of Warrant and Unvested Warrant Shares.In addition to any other limitation on transfer created by applicable securities laws: (a) this Warrant shall
not be transferable; and (b) Veloce shall not sell, assign, transfer, hypothecate, donate, encumber or otherwise dispose of any interest in any Warrant Shares that are deemed unvested pursuant to the terms of this Warrant.

11. Noncircumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its
Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant.

12. Mutilated, Lost, Stolen or Destroyed Warrant. In case this Warrant shall
be mutilated, lost, stolen or destroyed, the Company shall issue a new Warrant of like date, tenor and denomination and deliver the same in exchange and substitution for and upon surrender and cancellation of any mutilated Warrant, or in lieu of any
Warrant lost, stolen or destroyed, upon receipt of evidence satisfactory to the Company of the loss, theft or destruction of such Warrant, and upon receipt of indemnity satisfactory to the Company.

13. Warrant Holder Not Stockholder. This Warrant does not confer upon Veloce any right to vote or to consent as a
stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof as hereinbefore provided.

14. Severability. Should any part of this Warrant for any reason be declared invalid, such decision shall not affect the
validity of any remaining portion, which remaining portion shall remain in full force and effect as if this Warrant had been executed with the invalid portion thereof eliminated, and it is hereby declared the intention of the parties hereto that
they would have executed and accepted the remaining portion of this Warrant without including therein any such part, parts or portion which may, for any reason, be hereafter declared invalid.

15. Notices. Any notice or other communication required or permitted to be delivered to either party shall be in writing
and shall be deemed properly delivered, given and received (a) when received if hand delivered, (b) on confirmation by sender of receipt if sent by facsimile, or (c) on the first business day after being sent by registered overnight
mail, return receipt requested, by overnight courier or by overnight express delivery service, to the address or facsimile number set forth beneath the name of such party below (or to such other address or facsimile number as such party shall have
