1.1 Purposes of the Plan.

This Veloce Technologies, Inc. Employee Bonus Plan (the “Plan”) is established by the Board of Directors (the “Board”) of Veloce Technologies, Inc., a Delaware corporation (the “Company”), in connection with the Agreement and Plan of Merger, effective May 17, 2009 by and among Applied Micro Circuits Corporation, a Delaware corporation (“APM”), Espresso Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of APM (“Espresso”), the Company and Jeffrey Harrell, an individual, as representative of the stockholders of the Company, as amended on November 8, 2010 by Amendment No. 1 to Agreement and Plan of Merger (the “First Amendment”) and on April 5, 2012 by Amendment No. 2 to Agreement and Plan of Merger (the “Second Amendment”, together with the First Amendment, the “Merger Agreement”). The Plan is intended to (a) provide a bonus to certain of the Company’s employees and consultants who otherwise would have received stock option grants during the period between execution of the Merger Agreement and the Closing Date and (b) reward current and future employees and consultants of the Company and its Affiliates of outstanding ability and motivate such persons to exert their best efforts on behalf of the Company. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Merger Agreement.

1.2 Plan Administration.

(a) The authority to control and manage the operation and administration of this Plan shall be vested in the Board. The foregoing notwithstanding, the Board may expressly delegate to a subcommittee consisting of one or more officers and/or directors of the Company, the authority to administer the Plan, which subcommittee shall have all of the authority granted to the Board hereunder (the Board or a subcommittee to which authority has been delegated, the “Administrator”). Any such delegation of authority shall comply with the requirements of Section 157(c) of the General Corporation Law of the State of Delaware.

(b) Subject to the provisions hereof, (1) the Administrator shall have complete control of the administration of this Plan, with all powers necessary to enable it properly to carry out its duties; (2) the Administrator shall be authorized to interpret this Plan and shall have the discretion to determine all questions arising in the administration, construction and application of this Plan; and (3) the decisions of the Administrator upon all matters within the scope of its authority shall be conclusive and binding on all parties.

1.3 Definitions. The following terms shall have the following meanings when used in this Plan:

(a) “Affiliate” shall mean, with respect to any Person, any other Person that directly or indirectly through one or more intermediaries, controls, is controlled by or is under common control with, the Person in question.

(b) “Cause” shall mean any of the following: (i) the Participant’s refusal or failure to act in accordance with any specific, lawful direction or order of the Company or the surviving or acquiring entity following a change in control of the ownership of the Company (“Successor”); (ii) the unfitness or unavailability for service or unsatisfactory performance (other than as a result of death or Disability) of the Participant; (iii) the performance by Participant of any act or failure to perform any act in bad faith and to the detriment of the Company or a Successor; (iv) the Participant’s failure or inability to perform satisfactorily any reasonable assigned material duties of his or her position (other than as a result of his death or Disability); (v) the Participant’s dishonesty, intentional misconduct or material breach of any agreement with the Company or a Successor; or (vi) the Participant’s commission of a crime involving dishonesty, breach of trust, or physical or emotional harm to any person. Notwithstanding the foregoing, the definition of “Cause” in an individual written agreement between the Company and the Participant shall supersede the foregoing definition with respect to any Bonus Amount awarded to such Participant (it being understood, however, that if no definition of the term Cause is set forth in such an individual written agreement, the foregoing definition shall apply).

(c) “Consultant” shall mean an individual who is providing services as a consultant, adviser or other form of independent contractor eligible to receive an award under Rule 701 of the Securities Act of 1933, as amended, to the Company or an Affiliate of the Company.

3.3 Vesting, Other Performance Requirements and Forfeiture. In awarding any Bonus Amount, and subject to the process set forth in Section 3.1 hereof, the Administrator (i) may specify that the right to receive such Bonus Amount shall be conditional upon the fulfillment of specified conditions, including, without limitation, completion of specified periods of service in the service of the Company or an Affiliate, and the achievement of specified business and/or personal performance goals, and (ii) may provide for the forfeiture of all or any portion of any such Bonus Amount in specified circumstances. Subject to the process set forth in Section 3.1 hereof, the Administrator may also specify by whom and/or in what manner the accomplishment of any such performance goals shall be determined and may waive or modify any such required periods of service and/or performance goals or conditions.

3.4 Agreements. Any Bonus Amount awarded under the Plan may, in the Administrator’s discretion, be evidenced by an agreement at the time of grant of the Bonus Amount or thereafter, which, subject to the provisions of the Plan, may contain such terms and conditions as may be approved by the Administrator (subject to the process set forth in Section 3.1 hereof), and shall be executed by an officer of the Company on behalf of the Company or an Affiliate (an “Award Agreement”).

3.5 Bonus Payment. Each Participant’s Bonus Amount shall be paid by the Company in cash or shares of the Company’s stock as determined by the Board in its sole discretion, unless otherwise provided in an Award Agreement. The Company shall reserve out of its available authorized but unissued shares that number of shares of the Company’s common stock equal to the Carveout Units Amount in order to satisfy this liability in the event that the Bonus Pool is satisfied exclusively in shares of the Company’s common stock (“Bonus Plan Share Reserve”). Following the Closing Date, each Participant’s Bonus Amount shall be paid by APM in cash or shares of APM Common Stock as determined by APM in its sole discretion, unless otherwise provided in an Award Agreement. Subject to the satisfaction of any vesting requirements described in Section 3.3 above and other applicable requirements, any portion of a Participant’s Bonus Amount comprising a whole Unit shall be entitled to receive the same consideration as Company Restricted Shares as described under Section 1.9 of the Merger Agreement (provided, however, that subject to a Participant’s Award Agreement, such same consideration may be paid in the form of cash or shares of APM Common Stock, at APM’s option, as permitted by the Merger Agreement with respect to a Company Restricted Share, and such form of payment made in respect of a Unit need not be the same as the form of payment received by a Company Restricted Share pursuant to the Merger Agreement).

3.6 Termination. Unless otherwise provided in an Award Agreement, in the event of termination of Participant’s employment or other service, such Participant’s vested portion of the Bonus Amount shall be paid to the Participant in the same manner as Company Restricted Shares as set forth in Section 1.9 of the Merger Agreement. The unvested portion of the Bonus Amount shall be forfeited upon termination for any reason and the Participant shall have no further rights to payment with respect to such unvested portion.

3.7 Unallocated Portion of Aggregate Bonus Amount. Any distributable portion of the Bonus Pool that has not been allocated according to this Article III as of the Closing Date shall be retained by APM and may be allocated after the Closing Date subject to the terms of this Plan and Section 4.25 of the Merger Agreement.
