If (i) any payment of consideration is due and payable pursuant to any provision of this Agreement (including Section 1.8 or Section 1.9) or the Carveout Plan and the amount of such payment would, if Parent elected to pay the entire amount of such payment (together with all other payments due hereunder or under the Carveout Plan) in shares of Parent Common Stock pursuant to the terms of this Agreement or the Carveout Plan, as applicable, be subject to the approval of the holders of Parent Common Stock pursuant to NASDAQ Listing Rule 5635, and/or (ii) such shares of Parent Common Stock to be so paid shall not have been approved for listing on NASDAQ prior to the date of such issuance, then, in each of cases (i) and (ii), the date on which such payment is required to be made under this Agreement or the Carveout Plan, as applicable, shall, if so elected by Parent (which election shall be made in Parent’s sole and absolute discretion), be delayed by a period of time (not to exceed six (6) months) reasonably requested by Parent, in order to allow Parent to (x) obtain any such approval required under NASDAQ Listing Rule 5635 and/or (y) obtain such approval for listing on NASDAQ, as the case may be; provided, however, that if Parent seeks any such approval required under NASDAQ Listing Rule 5635 but fails to obtain such approval within such 6-month period, then such payment date shall, if so elected by Parent (which election shall be made in Parent’s sole and absolute discretion), be further delayed by an additional period of time (not to exceed three (3) months following the expiration of such prior 6-month period) reasonably requested by Parent, in order to allow Parent to raise any amount of capital or funds as may be necessary or advisable (in Parent’s sole and absolute discretion) prior to making such payment in cash. Parent shall at all times act in good faith in planning for and electing any such delay permitted by this Section 1.8(e) and shall, in good faith, seek to minimize the length of any such delay to extent commercially reasonable in Parent’s good faith judgment.

(f) Program Review.

(i) First Product Modifications. From and after the Amendment Date, Parent and the Company will meet yearly, to review and discuss the status of the Project, including without limitation the status of the “Veloce Minimum Requirements” (as set forth in the First Product Consideration Chart). In the event the Closing is effected, from and after the Effective Time such meetings will be held by the Veloce Steering Committee. In connection with each such meeting, Parent

Under 17 C.F.R. §§ 200.80(b)(4)

and 240.24b-2

and the Company, or the Veloce Steering Committee (as applicable), may solicit input from Vendor about the First Product with respect to the status of relevant Vendor deliverable releases, other similar products in the marketplace and evolving customer needs and requirements. Based upon such review and input, Parent and the Company, or the Veloce Steering Committee (as applicable), shall have the right to modify, by mutual written agreement, one or more of the Veloce Minimum Requirements and other performance features set forth in the First Product Consideration Chart, for the purpose of increasing the First Product’s competitive offering, accelerating its time to market or better conforming it to customer requirements. Such modifications may include raising or lowering particular Veloce Minimum Requirements or performance features, adding new requirements and features and eliminating existing requirements and features, and may or may not result in corresponding changes to the “Spin In Value Table” or “Performance Index Table” (as set forth in the First Product Consideration Chart). Notwithstanding the foregoing, nothing in this Section 1.8(f)(i) shall be deemed to require either party to agree to modify the Veloce Minimum Requirements or any other terms and provisions of the First Product Consideration Chart.

(ii) Second Product Performance Specifications and Modifications. From and after the Amendment Date, Parent and the Company will meet quarterly to review and discuss the status of the Second Product. In the event the Closing is effected, from and after the Effective Time such meetings will be held by the Veloce Steering Committee. In connection with each such meeting, Parent and the Company, or the Veloce Steering Committee (as applicable), may solicit input from prospective customers about the Second Product with respect to other similar products in the marketplace and evolving customer needs and requirements. Based upon such review and input, Parent and the Company, or the Veloce Steering Committee (as applicable), shall (A) timely establish the Second Product Performance Specifications and identify other Second Product structures (as contemplated in the definition of […***…] set forth in Exhibit A), and (B) have the right to modify, by mutual written agreement, one or more of the performance features of the Second Product and to approve and implement one or more additional enhancements, features or improvements to the Second Product processor core and/or fabric (each, a “Second Product Additional Feature”) for the purpose of increasing the Second Product’s competitive offering, accelerating its time to market or better conforming it to customer requirements. For so long as Xxxxxx Xxxxxxxxxxxxxxx (“Baktha”) serves on the Veloce Steering Committee and as chief executive officer of the Company or Merger Sub II, as applicable, each Second Product Additional Feature shall be mutually agreed upon by Baktha and the chief executive officer of Parent and, once the Merger has occurred, thereupon recommended by them to the Veloce Steering Committee for approval. In the event Baktha and Parent’s chief executive officer are unable to mutually agree upon a Second Product Additional Feature recommended by either of them, the matter shall be presented to and resolved by the Veloce Steering Committee. In the event the Veloce Steering Committee is unable to reach consensus in establishing the Second Product Performance Specifications or Second Product structures, or in approving a Second Product Additional Feature, the matter shall be resolved by the Governance and Nominating Committee of the Board of Directors of Parent, whose determination and approval shall be final and binding on all the parties. For the avoidance of doubt, any Second Product Additional Features the implementation of which would not reasonably be expected to cause the Second Product Milestone completion date to occur more than two quarters following completion of the […***…] Milestone shall be negotiated without the parties seeking any increase to the Adjusted Total Merger Consideration. Any disputes regarding whether one or more Second Product Additional Features would delay the Second Product Milestone completion date by more than two quarters beyond the completion of the […***…] Milestone shall be resolved in accordance with the dispute resolution procedure described above or, at the election of the Governance and Nominating Committee of the Board of Directors of Parent, by the dispute resolution procedures set forth in Section 9.2 of the Initial Agreement.

3 Certain Company Securities. Section 1.9 of the Initial Agreement is hereby amended and restated in its entirety as set forth below:

(a) Company Restricted Shares. In the event the Closing is effected, at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any securityholder of the Company, each Company Restricted Share (other than Dissenting Shares (as defined herein)) outstanding as of immediately prior to the Effective Time shall be converted into the right to receive, subject to Section 1.11 of the Agreement and Section 5 of this Amendment, the same consideration as a share of Company Common Stock as set forth under Section 1.8(a) above. Any vesting restrictions, forfeiture provisions or other contractual restrictions burdening a Company Restricted Share shall remain in effect and unaffected by the occurrence of the Merger or any event connected with the Merger, except as expressly provided for by the terms and conditions under which Company Restricted Shares were granted. In addition, all conditions and restrictions imposed on the determination of the consideration finally paid for a share of Company Common Stock under Section 1.8(a) (taking into account all other applicable sections of the Agreement, including without limitation, Section 1.8(d)) shall apply proportionally to the payments to be made under Section 1.8(a) in exchange for Company Restricted Shares. Parent shall make all required payments to former holders of Company Restricted Shares no later than the end of the calendar quarter during which such amounts shall become payable in accordance with this Section (provided that if such date shall fall within fifteen (15) days prior to the end of a calendar quarter, then Parent may, in its sole discretion, make such payment no later than the end of the next succeeding calendar quarter), and in Parent’s discretion may make such payments through a paying agent authorized by the Parent to administer such payments on the Parent’s behalf. All amounts payable pursuant to this Section 1.9(a) shall be subject to any required withholding of Taxes and shall be paid without interest.

(b) Company Stock Options. In the event the Closing is effected, at the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Company or any securityholder of the Company:

(i) each Vested Company Stock Option outstanding as of immediately prior to the Effective Time shall be automatically cancelled in exchange for the right to receive, subject to Section 5 of this Amendment, from Parent the same consideration (subject to Section 1.8(c)) as a share of Company Common Stock as set forth under Section 1.8(a) above, provided that such payments shall be reduced by the exercise price of such Vested Company Stock Option and no payments shall be made to the holder of a Vested Company Stock Option until such exercise price has been fully offset against the payments to be made hereunder. Any contractual restrictions burdening a Vested Company Stock Option shall remain in effect and unaffected by the occurrence of the Merger or any event connected with the Merger, except as expressly provided for by the terms and conditions under which such Vested Company Stock Options were granted. In addition, all conditions and restrictions imposed on the determination of the consideration finally paid for a share of Company Common Stock under Section 1.8(a) (taking into account all other applicable sections of the Agreement, including without limitation, Section 1.8(d)) shall apply proportionally to the payments made under Section 1.8(a) in exchange for Vested Company Stock Options. All amounts payable pursuant to this Section 1.9(b)(i) shall be paid without interest.

(ii) each Unvested Company Stock Option outstanding as of immediately prior to the Effective Time shall be automatically cancelled and shall thereafter be of no further force or effect.

(iii) All amounts payable pursuant to this Section 1.9(b) shall be subject to any required withholding of Taxes.

(c) Other Company Securities. Prior to the Effective Time, the board of directors of the Company shall approve all resolutions required in order to provide that, as of immediately prior to the Effective Time, (i) each then outstanding: (A) subscription, option, call, warrant or other right (whether or not currently exercisable) to acquire any shares of capital stock or other securities of the Company; (B) security, instrument or obligation that is or may become convertible into or exchangeable for any shares of capital stock or other securities of the Company; (C) Contract under which the Company is or may become obligated to sell or otherwise issue any shares of its capital stock or any other securities of the Company; and (D) share of restricted stock of the Company (clauses (A) through (D) above, collectively “Company Securities”) (other than Company Stock Options, Company Restricted Shares and Units (as defined in the Carveout Plan)), shall be accelerated in its and their entirety effective as of immediately prior to the Effective Time, and all forfeiture rights with respect thereto in favor of the Company shall lapse in their entirety as of such time, and (ii) that each Company Security that has not been exercised, or remains subject to a right of forfeiture in favor of the Company, in either case as of immediately prior to the Effective Time (but after giving effect to the acceleration, if any, provided under clause (i) hereof), shall terminate and be canceled as of the Effective Time and the holders thereof shall have no further rights with respect thereto, except as may be provided in Section 1.9(a) with respect to Company Restricted Shares or Section 1.9(b) with respect to Company Stock Options.

(d) Prior to the Closing Date, the Company shall take all actions reasonably necessary or advisable to allow for the treatment of the Company Securities contemplated by paragraphs (a), (b) and (c) of this Section under the terms of the Company Stock Option Plan and any and all other Contracts evidencing or governing Company Securities, including the amendment of any of the foregoing or the giving of any notice required under the Company Stock Option Plan or any such Contract relating to the Company Securities and, without limiting the generality of the foregoing, the Company shall pass all appropriate resolutions and give all consents, approvals and waivers that are reasonably necessary or advisable to allow for the treatment of the Company Securities as contemplated by paragraphs (a), (b) and (c) of this Section, and the Company shall use its reasonable best efforts to obtain from each holder of a Vested Company Stock Option an executed instrument pursuant to which each such holder acknowledges and agrees to its indemnification obligations hereunder and appoints of the Stockholders’ Representative as its agent and attorney in fact for the same purposes, and upon the same terms (mutatis mutandis), as such Stockholders’ Representative is appointed under Section 9.1 with respect to the stockholders of the Company. The Stockholders’ Representative hereby accepts such appointment by such holders of Vested Company Stock Options.

4 Exchange of Certificates. Section 1.11(a) of the Initial Agreement is hereby amended and restated in its entirety as set forth below:

As soon as practicable but in any event within seven (7) Business Days after the Effective Time, Parent will send to each of the registered holders of Company Stock Certificates a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify and instructions for use in effecting the surrender of Company Stock Certificates in exchange for the consideration due to each such holder calculated in accordance with Section 1.8(a). Upon surrender of a Company Stock Certificate to Parent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably requested by Parent, Parent shall deliver to the holder of such Company Stock Certificate, (A) that portion, if any, of the Accelerated Consideration Amount and Merger Per Share Consideration, as the case may be, that such holder has the right to receive at such time pursuant to Section 1.8(a) in cash, via wire transfer in immediately available funds, and (B) a certificate representing that number of shares of Parent Common Stock, if any, that such holder has the right to receive at such time pursuant to

*** Text Omitted and Filed Separately

Confidential Treatment Requested

Under 17 C.F.R. §§ 200.80(b)(4)

and 240.24b-2

Section 1.8(a), provided that any certificates representing Parent Common Stock to be delivered to the holder of a Company Stock Certificate pursuant to this Section shall, in each case, represent only whole shares of Parent Common Stock. In lieu of any fractional shares to which such holder would otherwise be entitled, after combining any fractional interests of such holder into as many whole shares as is possible, the holder of such Company Stock Certificate shall be entitled to receive cash in an amount equal to the dollar amount (rounded to the nearest whole cent) determined by multiplying the Applicable Parent Share Price by the fraction of a share of Parent Common Stock that would otherwise be deliverable to such holder pursuant to this Section. All Company Stock Certificates so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.11, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive the consideration due to such holder calculated in accordance with Section 1.8(a). If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the payment of any cash or issuance of any certificate representing Parent Common Stock or the payment of cash in lieu of fractional shares, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Stock Certificate.

5 Certain Indemnification-Related Matters.

(a) Elimination of Escrow. The Parties agree that the escrow arrangements relating to consideration to be paid to Entitled Holders under the Agreement shall cease to apply from and after the Amendment Date. Accordingly, (i) Section 1.13 of the Initial Agreement is hereby deleted in its entirety and shall be of no further force and effect, (ii) all references to the “Escrow Agreement” and the “Escrow Agent” in the Initial Agreement are hereby deleted therefrom, (iii) in each place where the term “Escrow Period” appears in the Initial Agreement, it shall be replaced with the term “Survival Period,” (iv) “Survival Period” shall mean the period beginning on the date of the Initial Agreement and ending at 11:59 p.m. Pacific Time on the date that is the first-year anniversary of the 10^th Business Day following the occurrence of the First Product […***…] Milestone, (v) where the term “Closing Date” appears in Section 8.1(a) of the Initial Agreement, it shall be replaced with “occurrence of the First Product […***…] Milestone” and (vi) in each place where the term “Escrow Fund” appears in the Initial Agreement, it shall be replaced with the term “Unpaid Consideration Fund”, (vi) “Unpaid Consideration” means, as of any given time, any and all consideration that would be due hereunder or under the Carveout Plan from Parent to the Entitled Holders and holders of Units under the Carveout Plan if all conditions to such payment were satisfied, but which consideration has yet to be paid by Parent (provided, however, that any consideration that has become payable to such a holder hereunder pursuant to Section 1.8(a)(i) or Section 1.9 but which has yet to be paid solely due to vesting restrictions continuing to apply to such holder with respect to such consideration shall not be deemed to be “Unpaid Consideration”) and (vii) “Unpaid Consideration Fund” means, as of any given time, an amount of Unpaid Consideration equal to the lesser of (I) the Unpaid Consideration as of such time and (II) the difference of (A) the product of (x) 0.1 multiplied by (y) the greater of (1) the Accelerated Consideration Amount and (2) the Adjusted Total Merger Consideration (if then known), minus (B) the amount of the Unpaid Consideration Fund that was previously used to offset Losses in accordance with Section 8.3.

Under 17 C.F.R. §§ 200.80(b)(4)

and 240.24b-2

(b) Offset Against Unpaid Consideration Fund. Section 8.3 of the Initial Agreement is hereby amended and restated in its entirety as set forth below:

(a) Notwithstanding anything to the contrary in Sections 1.8 or 1.9 or any other provision of this Agreement or any Related Agreement but subject to the limitations set forth in Section 5(a) of this Amendment and Section 8.4 of the Initial Agreement as amended hereby, in the event any Indemnified Party shall suffer any Losses for which such Indemnified Party is entitled to indemnification under this Section 8, such Indemnified Party shall be entitled to recover such Losses by offsetting the aggregate amount of such Losses against the Unpaid Consideration Fund by permanently retaining and withholding from payment to the Entitled Holders an amount of consideration otherwise due hereunder equal to the aggregate amount of the Losses. Any amount so permanently retained and withheld shall be permanently retained and withheld from payments otherwise due hereunder or under the Carveout Plan, as applicable, to Entitled Holders and holders of Units (as defined in the Carveout Plan) on a pro rata basis, assuming for these purposes that the full Carveout Units Amount has been issued and is vested under the Carveout Plan. Prior to effecting any such offset, Parent shall deliver a written claim notice (a “Claim Notice”). Each Claim Notice shall contain a reasonably detailed summary of the basis for the claim, the provision or provisions of the Agreement giving rise to the claim and, if known, the estimated amount of the Losses incurred or reasonably expected to be incurred by the Indemnified Party as a result of such inaccuracy or breach under which such indemnification is sought (the “Claimed Amount”). Following the delivery of such notice, to the fullest extent permitted by applicable Law, Parent shall be entitled to retain in the Unpaid Consideration Fund (and, notwithstanding anything to the contrary contained herein or in the Carveout Plan, shall not be obligated to pay to any Entitled Holder or holder of Units under the Carveout Plan) an amount equal to the Claimed Amount until any dispute in relation thereto is resolved in accordance with the process set forth in Section 8. For the avoidance of doubt, nothing contained in the Agreement or any Related Agreement shall be construed to require Parent to establish a separate fund or account or to otherwise hold separate or segregate any funds as part of the Unpaid Consideration Fund. Unless and until actually paid by Parent to the Entitled Holders hereunder or to holders of Units under the Carveout Plan, Parent shall be the owner of the Unpaid Consideration Fund for all purposes hereunder and under applicable Law, and no Entitled Holder or holder of Units under the Carveout Plan shall have any rights thereto, except to the extent expressly set forth in this Agreement or the Carveout Plan, as applicable.

(b) Within thirty (30) calendar days after receipt by the Stockholders’ Representative of a Claim Notice, the Stockholders’ Representative may deliver to Parent a written response (the “Response Notice”) in which the Stockholders’ Representative: (a) agrees that an amount equal to the full Claimed Amount may be offset against the Unpaid Consideration Fund; (b) agrees that an amount equal to part, but not all, of the Claimed Amount (the “Agreed Amount”) may be offset against the Unpaid Consideration Fund; or (c) indicates that no part of the Unpaid Consideration Fund may be offset in respect of the Claimed Amount. Any part of the Claimed Amount that is not agreed to be released to the Indemnified Party pursuant to the Response Notice, which determination shall be made in good faith by the Stockholders’ Representative, shall be the “Contested Amount.” If a Response Notice is not received by the Parent within such thirty (30)-day period, then the Stockholders’ Representative shall be conclusively deemed to have agreed that an offset to the Unpaid Consideration Fund equal to the full Claimed Amount may be used by Parent.

(c) If the Stockholders’ Representative delivers a Response Notice indicating that there is a Contested Amount, the Stockholders’ Representative and Parent shall attempt in good faith to resolve the dispute related to the Contested Amount within ten (10) Business Days of Parent’s receipt of such Response Notice (the “Negotiation Period”). If the Indemnified Party

and 240.24b-2

and the Stockholders’ Representative resolve such dispute, such written resolution shall be binding on all Entitled Holders and holders of Units under the Carveout Plan and such Indemnified Party, and a settlement agreement shall be signed by Parent (on behalf of such Indemnified Party) and the Stockholders’ Representative. If Parent and the Stockholders’ Representative fail to reach agreement by the end of the Negotiation Period, each party shall be entitled to its legal remedies in accordance with the Agreement.

(c) Limitations. Sections 8.4(b), (c) and (d) of the Initial Agreement are hereby amended and restated in their entirety as set forth below:

(b) The limits set forth in Section 8.4(a) shall not apply to breaches of the Company Special Representations. In the case of breaches of the Company Special Representations, after the Indemnified Parties have exhausted all amounts available from the Unpaid Consideration Fund, the Indemnified Parties shall be permitted to seek recovery for Losses suffered by the Indemnified Parties directly from the Entitled Holders or holders of Units under the Carveout Plan, provided that each Entitled Holder or holder of Units under the Carveout Plan shall be liable, on a several and not joint basis, solely for such Entitled Holder’s or Unit holders’ pro rata amount of any Losses resulting therefrom.

(c) In no event will an Entitled Holder or a holder of Units under the Carveout Plan be liable for any amount in respect of any Losses suffered by any of the Indemnified Parties pursuant to this Agreement in excess of the aggregate value of the consideration actually received by such Entitled Holder or Unit holder pursuant to this Agreement.

(d) Notwithstanding the foregoing, none of the limitations set forth in this Section 8.4 shall apply in the case of fraud or willful breach or intentional misrepresentation by the Company (or an Entitled Holder or holder of Units under the Carveout Plan, as applicable).

(d) Appointment of Stockholders’ Representative. Upon approval of the Agreement (including, for the avoidance of doubt, this Amendment) by the requisite majority of the Company’s stockholders, all such stockholders shall, without any further act of any Company stockholder, be deemed to have consented to and approved (i) the use of the Unpaid Consideration Fund as collateral to secure the rights of the Indemnified Parties under Section 8 in the manner set forth herein and in the Initial Agreement, and (ii) the appointment of the Stockholders’ Representative as the representative under the Agreement (including, for the avoidance of doubt, this Amendment) of the Persons receiving consideration hereunder and as the attorney-in-fact and agent for and on behalf of each such Person (other than holders of Dissenting Shares).

(e) Form of Escrow Agreement. The Form of Escrow Agreement attached as Exhibit 1.13 to the Initial Agreement is hereby deleted in its entirety and shall be of no further force and effect.

6 Termination Events.

(a) Section 7.1(e) of the Initial Agreement is hereby amended and restated in its entirety as set forth below:

by Parent, if this Agreement and the Merger shall not have been approved within twenty-four (24) hours from 11:59 p.m. Pacific Time on the date on which Section 6(a) of the Securityholder Agreement becomes effective by the vote of the stockholders of the Company holding seventy percent (70%) of the issued and outstanding shares of capital stock of the Company;

and 240.24b-2

(b) Section 7.1(g) of the Initial Agreement is hereby amended and restated in its entirety as set forth below:

by written notice by the Company to Parent or Parent to the Company, as the case may be, in the event the Closing has not occurred on or prior to November 30, 2014 (the “Final Termination Date”) for any reason other than delay or nonperformance of or breach by the party seeking such termination.

by written notice by Parent to the Company, in the event that the Company has not (i) adopted the Carveout Plan as set forth in Section 4.19, (ii) otherwise complied with the provisions of Section 4.19, or (iii) prior to the Closing Date, has not reserved sufficient available shares of the Company’s common stock such that in the event of the issuance of such shares in satisfaction of the Company’s liabilities under the Carveout Plan (assuming all Units permitted to be granted thereunder were granted and vested) the Company would not be required to deplete the reserve of the Company’s 2009 Stock Incentive Plan, it being understood and agreed that the shares reserved in connection with the Carveout Plan must be duly authorized, fully paid and non-assessable.

7 Treatment of the Merger. Section 1.15 of the Initial Agreement is hereby amended and restated in its entirety as follows:

Treatment of the Merger. The Parties intend that, for federal income tax purposes, (a) if the Second Merger occurs, the Merger and the Second Merger, taken together, constitute a “reorganization” within the meaning of Section 368(a) of the Code (a “Reorganization”), provided that all of the requirements for such treatment are otherwise satisfied, or (b) if the Second Merger does not occur, or if the Merger and the Second Merger, taken together, do not satisfy all requirements for treatment as a Reorganization, that (i) the Merger be treated as a taxable purchase of the stock of the Company by Parent and (ii) the Second Merger, if it occurs, be treated as a liquidation of the Company into Parent as described in Section 332 of the Code. To the extent the Merger and the Second Merger, taken together, otherwise constitute a Reorganization, the parties intend for federal income tax purposes that this Agreement constitute a “plan of reorganization” within the meaning of section 1.368-2(g) of the regulations promulgated under the Code.

8 Certain Covenants, Agreements, Etc. Section 4 of the Initial Agreement is hereby amended as follows:

(a) The following shall be added to the Initial Agreement as Section 4.18 thereof:

R&D/Engineering Organization. From and after the consummation of the Merger and until the achievement of the Second Product Milestone or (if earlier) the Second Product Deadline, Parent shall (i) maintain the Company or Merger Sub II, as applicable, as a separate legal entity and wholly-owned subsidiary of Parent, with Baktha as its chief executive officer, (ii) for so long as Baktha serves on the Veloce Steering Committee and as chief executive officer of the Company’s R&D/Engineering organization as existing immediately prior to the Closing, as the same may be subsequently changed by the Veloce Steering Committee (the “Veloce Organization”), substantially maintain intact the Veloce

*** Text Omitted and Filed Separately

Under 17 C.F.R. §§ 200.80(b)(4)

and 240.24b-2

Organization and reporting structure consistent with the normal corporate governance principles applicable to a wholly-owned subsidiary of Parent (provided however that, in no event shall voluntary departures or terminations for good cause be deemed to constitute a breach of this provision), (iii) for so long as Baktha serves on the Veloce Steering Committee and as chief executive officer of the Veloce Organization, continue to operate the Veloce Organization in the ordinary course of its business consistent with its past practices as the same may be subsequently changed by the Veloce Steering Committee (provided however that, neither the Merger nor the Second Merger shall be deemed to constitute a breach of this provision), and (iv) timely make available such resources as are reasonably required in order to achieve the First Product […***…] Milestone, […***…] Milestone and the Second Product Milestone on or prior to the Second Product Deadline. In the event of a material breach of this Section 4.18 which remains uncured and undisputed by Parent following thirty (30) days written notice from the Stockholders’ Representative of such breach, the First Product […***…] Milestone, the […***…] Milestone or the Second Product Milestone, as applicable, shall be deemed to be met by the Company; provided, however, that any such asserted breach that is disputed by Parent shall be resolved as follows: (A) disputes that are solely technical disputes as described in Section 9.2 of the Initial Agreement shall be resolved in accordance with the dispute resolution procedures set forth in Section 9.2 of the Initial Agreement and Parent’s 30-day cure period shall not commence unless and until a breach has been determined to have occurred by the Performance Arbitrator described in such Section 9.2, and (B) all other disputes shall be resolved in good faith by the Veloce Steering Committee, provided that any such disputes that the Veloce Steering Committee is unable to resolve shall be resolved by the Governance and Nominating Committee of the Board of Directors of Parent, with the Stockholders’ Representative having the right to appeal any adverse determination of such Committee to the full Board of Directors of Parent, whose determination of such appeal shall be final; Parent’s 30-day cure period shall not commence unless and until a breach has been finally determined to have occurred pursuant to the foregoing procedure. Nothing in this Section 4.18 shall be deemed to amend or modify that certain employment letter agreement by and between Parent and Baktha dated November 8, 2010.

(b) The following shall be added to the Initial Agreement as Section 4.19 thereof:

Carveout Plan. The Board of Directors of the Company shall, promptly following the Amendment Date (but in no event later than ten (10) Business Days thereafter), adopt the Carveout Plan and shall abide by the terms of the Carveout Plan from such date of adoption until the Effective Time. Between the Effective Time and the 10th Business Day following the satisfaction of the Second Target Reserve Consideration Conditions, Parent shall grant in accordance with the terms and conditions of the Carveout Plan, or shall cause to be granted in accordance with the terms and conditions of the Carveout Plan, to employees and/or former employees of the Company or replacement hires for such employees and/or former employees who have terminated their employment with the Company or Parent following the Effective Time an aggregate number of Units (as defined in the Carveout Plan) equal to the Carveout Units Amount minus the number of Units (including, for the avoidance of doubt, both vested or unvested Units) outstanding under the Carveout Plan immediately prior to the Effective Time. Parent shall consult with the Veloce Steering Committee with respect to such Carveout Plan grants, it being understood and agreed that, subject to such consultation, the date on which each such grant is made (so long as it occurs prior to the 10th Business Day following the satisfaction of the Second Target Reserve Consideration Conditions), the size of each such grant, the identity of such employee, former employee or replacement hire receiving each such grant, and the vesting schedule applicable to each such grant shall be as recommended by the Veloce Steering Committee, subject to customary review and approval of the Governance & Nominating Committee of the Board of Directors of Parent. Notwithstanding anything herein to the contrary, the Parties agree that, unless otherwise consented to by Parent in its sole and absolute discretion, neither Sheffield nor Baktha, nor any members of Baktha’ family, shall, directly or indirectly, be awarded, granted or permitted to otherwise beneficially own any Units (as defined in the Carveout Plan).

(f) The following shall be added to the Initial Agreement as Section 4.23 thereof (and shall, for the avoidance of doubt, be binding upon Merger Sub II):

Second Merger. Unless Parent determines that it is unlikely that the Merger and the Second Merger, taken together, will constitute a Reorganization, immediately following the Merger, Parent shall cause the Surviving Corporation to be merged with and into Merger Sub II, with Merger Sub II surviving the Merger (the “Second Merger” and, together with the Merger, the “Mergers”). The Second Merger, if it occurs, shall be effected by, among other things, adopting and causing the Surviving Corporation to adopt an agreement and plan of merger and reorganization pursuant to which the Surviving Corporation shall be merged with and into Merger Sub II, with Merger Sub II being the entity surviving the Second Merger as a wholly owned subsidiary of Parent. There shall be no conditions to the Second Merger, other than the consummation of the Merger and no determination by Parent as described above. Parent, Merger Sub and the Company agree that Merger Sub II shall be a disregarded entity for federal income tax purposes unless and until Parent determines otherwise. The Company hereby represents and warrants to Parent, Merger Sub and Merger Sub II that neither the Company nor, to the Company’s Knowledge, any of its Affiliates has taken or agreed to take action that would prevent the Merger and the Second Merger, taken together, from constituting a Reorganization (provided that compliance with the terms of this Agreement or any agreement contemplated by this Agreement shall not constitute a breach of this representation). Neither Parent nor any of its Affiliates or Representatives shall (a) have any obligation to cause the Second Merger to occur or to cause the Merger and the Second Merger, taken together, to constitute a Reorganization, or (y) be liable to the Company, any Entitled Holders or any other Person if for any reason the Second Merger does not occur or the Merger and the Second Merger, taken together, do not constitute a Reorganization. Each of the Parties hereby agrees (and hereby provides any necessary consents to effect such agreement) that if the Second Merger occurs, automatically and without any further action on the part of any Party, as a result of the Second Merger, all of the Surviving Corporation’s rights and obligations under this Agreement and any Related Agreement (including, for the avoidance of doubt, any rights to indemnification and any rights the Surviving Corporation has as a result of the Merger) shall be deemed to be assigned to Merger Sub II and any and all such rights may be exercised by, and any and all such obligations shall be performed by, Merger Sub II as though it were the Surviving Corporation.

(g) The following shall be added to the Initial Agreement as Section 4.24 thereof:

Parent shall consult with the Veloce Steering Committee with respect to such Parent Equity Grants, it being understood and agreed that, subject to such consultation, the date on which each such grant is made (so long as it occurs prior to the 30th day following the satisfaction of the Second Target Reserve Consideration Conditions), the size of each such grant, the identity of such employee, former employee, new hire, consultant or independent contractor receiving each such grant, and the vesting schedule applicable to each such grant, shall be as recommended by the Veloce Steering Committee, subject to customary review and approval of the Governance & Nominating Committee of the Board of Directors of Parent. Notwithstanding the foregoing, at any time and from time to time at the request of Parent, the Veloce Steering Committee may elect (subject to customary review and approval of the Governance & Nominating Committee of the Board of Directors of Parent) to satisfy all or a portion of a Parent Equity Grant by instead granting a cash award (which may be subject to vesting and other similar restrictions).

The Company shall use its commercially reasonable efforts to cause the Information Statement to comply in all material respects with applicable federal securities laws and state corporate and securities laws. Each of the Company and Parent shall provide promptly to the other party such information concerning its respective business and financial statements and affairs as, in the reasonable judgment of the requesting party or its counsel, may be required or appropriate for inclusion in the Permit Application (including, without limitation, the Information Statement to be provided by the Company), the Hearing Notice or the Information Statement, or in any amendments or supplements thereto, and to cause its counsel and auditors to cooperate with the other’s counsel and auditors in the preparation of the Permit Application, the Hearing Notice and the Information Statement.

(a) The authorized capital stock of the Company consists of: (i) 12,500,000 shares of Company Common Stock, of which 6,808,908 shares have been issued and are outstanding as of the Amendment Date. There are no authorized, issued or outstanding shares of capital stock of the Company other than Company Common Stock. All of the outstanding shares of Company Common Stock have been duly authorized and validly issued, and are fully paid and non assessable. All of the outstanding shares of Company Common Stock and all outstanding Company Securities have been issued and granted in compliance with (i) all applicable securities laws and other applicable Laws, and (ii) all requirements set forth in the Company Constituent Documents and applicable Contracts. Each of the Company’s stockholders is the record and beneficial owner of the shares of the Company Common Stock as set forth opposite such stockholder’s name on Part 2.5(a) of the Company Disclosure Schedule, and such shares are free and clear of all Encumbrances (other than those Encumbrances relating to applicable securities laws).

and 240.24b-2

extent) the vesting of such Company Security will be accelerated in any way by the transactions contemplated by this Agreement or by the termination of employment or engagement or change in position of any holder thereof following consummation of the Merger; and (G) whether such Company Security has been designated an “incentive stock option” as defined in Section 422 of the Code.

(e) The Company is not now, nor has it ever been, required to file with the SEC any periodic or other reports, or any registration statement, pursuant to the Securities Act or the Exchange Act.

12 Assumption of Company Stock Option Plan and Carveout Plan. A new Section 9.19 shall be added to the Initial Agreement as follows:

Assumption of Company Stock Option Plan and Carveout Plan. At the Effective Time, Parent shall assume each of the Company Stock Option Plan and the Carveout Plan and shall act as the sponsor of each such plan on and after the Effective Time in accordance with its terms (as adjusted to reflect the role of Parent as the sponsor of the such plan and, in the case of the Company Stock Option Plan, the issuance of shares of Parent Common Stock in connection with the grant of awards under such plan).

This Amendment amends, restates and replaces in its entirety the First Amendment, which shall be null and void and of no further force and effect from and as of the date hereof.
