 M/A-COM TECHNOLOGY SOLUTIONS HOLDINGS, INC. 

U.S. EMPLOYEE STOCK PURCHASE PLAN 
 SECTION 1. PURPOSE 
 The purpose of the Plan is to provide employees of the Company and its
Designated Subsidiaries with an opportunity to purchase Common Stock of the Company. It is the intention of the Company to have the Plan qualify as an “employee stock purchase plan” under Section 423 of the Code, but the Company makes
no representation of such status or undertaking to maintain such status. The provisions of the Plan, accordingly, shall be construed so as to extend and limit participation in a manner consistent with the requirements of Section 423 of the
Code. 
 SECTION 2. DEFINITIONS 
 Certain capitalized terms used in the Plan have the meanings set forth in Appendix A. 
 SECTION 3. ELIGIBILITY REQUIREMENTS 
  

	3.1	Initial Eligibility 

 Except as provided
in Section 3.2, each Employee shall become eligible to participate in the Plan in accordance with Section 4 on the first Enrollment Date on or following the later of (a) the date such Employee begins employment and (b) the
Effective Date. Participation in the Plan is entirely voluntary. 
  

	3.2	Limitations on Eligibility 

 The following
Employees are not eligible to participate in the Plan: 
 (a) Employees whose customary employment is twenty (20) hours or less per week;
and 
 (c) Employees who, immediately upon purchasing Shares under the Plan, would own directly or indirectly, an aggregate of five percent
(5%) or more of the total combined voting power or value of all outstanding shares of all classes of stock of the Company or any Subsidiary (and for purposes of this paragraph, the rules of Section 424(d) of the Code shall apply, and stock
which the Employee may purchase under outstanding options shall be treated as stock owned by the Employee). 
 SECTION 4.
ENROLLMENT 
  

	4.1	First Offering Period 

 Any Eligible
Employee immediately prior to the first Offering Period under the Plan will be automatically enrolled in the first Offering Period. An Eligible Employee will be eligible to 

  
 US-1

 
continue participation in the first Offering Period only if such individual completes and signs an enrollment election form (or completes such other enrollment procedure established by the
Committee) and submits such enrollment election to the Company (a) no earlier than the effective date of the Form S-8 registration statement with respect to the issuance of Shares under the 2012 Employee Stock Purchase Plan and (b) no
later than ten (10) business days following the effective date of such S-8 registration statement or such other period of time as the Committee may determine (the “Enrollment Window”). An Eligible Employee’s failure to
submit the enrollment election form (or complete such other enrollment procedure permitted by the Committee) during the Enrollment Window will result in the automatic termination of such individual’s participation in the first Offering Period.

  

	4.2	Subsequent Offering Periods 

 Subsequent
to commencement of the first Offering Period, any Eligible Employee may enroll in the Plan for an Offering Period by completing and signing an enrollment election form or by such other means as the Committee shall prescribe and submitting such
enrollment election to the Company in accordance with procedures established by the Committee on or before the Cut-Off Date with respect to such future Offering Period. 

 

	4.3	Continuing Effectiveness of Enrollment Election 

 Unless otherwise determined by the Committee, the enrollment election and the designated rate of payroll deduction shall continue for future Offering Periods unless the Participant changes or cancels, in
accordance with procedures established by the Committee, the enrollment election or designated rate of payroll deduction prior to the Cut-Off Date with respect to a future Offering Period or elects to withdraw from the Plan in accordance with
Section 8.1. 
 SECTION 5. GRANT OF OPTIONS ON ENROLLMENT 

 

	5.1	Option Grant 

 Enrollment by an Eligible
Employee in the Plan as of an Enrollment Date will constitute the grant by the Company to such Participant of an option on such Enrollment Date to purchase Shares from the Company pursuant to the Plan. 

 

	5.2	Option Expiration 

 An option granted to a
Participant pursuant to the Plan shall expire, if not terminated for any reason first, on the earliest to occur of: (a) the end of the Offering Period in which such option was granted; (b) the completion of the purchase of Shares under the
option under Section 7; or (c) the date on which participation of such Participant in the Plan terminates for any reason. 

  
 US-2

	5.3	Purchase of Shares 

 (a) An option granted
to a Participant under the Plan shall give the Participant a right to purchase on a Purchase Date the largest number of whole Shares, as determined by the Committee, which the funds accumulated in the Participant’s Account as of such Purchase
Date will purchase at the applicable Purchase Price; provided, however, that, unless the Committee determines otherwise for a future Offering Period or Purchase Period, no Participant may purchase during a Purchase Period more than 625 Shares,
subject to adjustment as provided in Section 9 of the Plan. 
 (b) Notwithstanding anything to the contrary herein, to the extent required
by Section 423 of the Code, no Employee shall be granted an option under the Plan (or any other plan of the Company or a Subsidiary intended to qualify under Section 423 of the Code) which would permit the Employee to purchase Shares under
the Plan (and such other plan) in any calendar year with a Fair Market Value (determined at the time such option is granted) in excess of $25,000. 
 (c) Any payments made by a Participant in excess of the limitations of this Section 5.3 shall be returned to the Participant in accordance with procedures established by the Committee. 

SECTION 6. PAYMENT 
 (a)
The Committee may designate the time and manner for payment of Shares to be purchased during the Purchase Period, including, but not limited to, through payroll deductions from Eligible Compensation, the terms and conditions of which are designated
by the Committee; provided, however, that unless the Committee determines otherwise for a future Purchase Period, any payroll deductions must be in one percent (1%) increments comprising not less than one percent (1%) and not more than
fifteen percent (15%) of a Participant’s Eligible Compensation received on each pay day during the Purchase Period. Payment amounts shall be credited on a bookkeeping basis to a Participant’s Account under the Plan. All payment
amounts may be used by the Company for any purpose and the Company shall have no obligation to segregate such funds. No interest accrues on payments by Participants. 
 (b) Any payroll deductions for a Participant shall commence on the first pay day following the Enrollment Date and will end on the last pay day prior to the Purchase Date; provided, however, that for the
first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window. 

SECTION 7. PURCHASE OF SHARES 
  

	7.1	Option Exercise 

 Any option held by a
Participant that was granted under the Plan and that remains outstanding as of a Purchase Date shall be deemed to have been exercised on such Purchase Date for the number of whole Shares, as determined by the Committee, that the funds

  
 US-3

 
accumulated in the Participant’s Account as of the Purchase Date will purchase at the applicable Purchase Price (but not in excess of the number of Shares for which options have been granted
to the Participant pursuant to Section 5.3). Options for other Shares for which options have been granted that are not purchased on the last Purchase Date during the Offering Period shall terminate. Shares shall not be issued with respect to an
option unless the exercise of such option and the issuance and delivery of such Shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended,
the Securities Exchange Act of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed. As a condition to the exercise of an option, the Committee may
require the person exercising such option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares. 

 

	7.2	Refund of Excess Amount 

 If, after a
Participant’s exercise of an option under Section 7.1, an amount remains credited to the Participant’s Account as of a Purchase Date (including after return of any amount pursuant to Section 5.3(c)), then the remaining amount
shall be (a) if no further Purchase Periods are immediately contemplated by the Committee, distributed to the Participant as soon as administratively feasible, or (b) if another Purchase Period is contemplated by the Committee, carried
forward in the Account for application to the purchase of Shares on the next following Purchase Date. 
  

	7.3	Employees of Subsidiary 

 In the case of
Participants employed by a Designated Subsidiary, the Committee may provide for Shares to be sold through the Subsidiary to such Participants, to the extent consistent with Section 423 of the Code. 

 

	7.4	Pro Rata Allocation 

 If the total number
of Shares for which options are or could be exercised on any Purchase Date in accordance with this Section 7, when aggregated with all Shares for which options have been previously exercised under the Plan, exceeds the maximum number of Shares
reserved in Section 12, the Company may, in accordance with Section 12, allocate the Shares available for delivery and distribution in the ratio that the balance in each Participant’s Account bears to the aggregate balances of all
Participants’ Accounts, and the remaining balance of the amount credited to the Account of each Participant under the Plan shall be returned to him or her as promptly as possible. 

 

	7.5	Notice of Disposition 

 If a Participant
or former Participant who is subject to United States federal income tax sells, transfers, or otherwise makes a disposition of Shares purchased pursuant to an option granted under the Plan, then such Participant or former Participant shall notify
the Company or the Employer in writing of such sale, transfer or other disposition within ten (10) days of the 

  
 US-4

 
consummation of such sale, transfer, or other disposition. Without limitation on the Participant’s or former Participant’s ability to sell, transfer or otherwise make a disposition of
Shares and without limitation on Section 11.2, Participants and former Participants must maintain any Shares purchased pursuant to an option granted under the Plan within two (2) years after the date such option is granted or within one
(1) year after the date such Shares were transferred to the Participant at the broker designated by the Committee, unless the Committee determines otherwise. 
 SECTION 8. WITHDRAWAL FROM THE PLAN, TERMINATION 
 OF EMPLOYMENT, AND
LEAVES OF ABSENCE 
  

	8.1	Withdrawal From the Plan 

 A Participant
may withdraw all funds accumulated in the Participant’s Account from the Plan during any Purchase Period by delivering a notice of withdrawal to the Company or the Employer (in a manner prescribed by the Committee) at any time up to but not
including the ten (10) days prior to the Purchase Date for such Purchase Period, or by such longer time period in advance of the Purchase Date as the Committee may require. If notice of complete withdrawal from the Plan as described in the
preceding sentence is timely received, the Company or the Employer will cease the Participant’s payroll withholding for the Plan and all funds then accumulated in the Participant’s Account shall not be used to purchase Shares, but shall
instead be distributed to the Participant as soon as administratively feasible. An Employee who has withdrawn from a Purchase Period may not return funds to the Company or the Employer during that Purchase Period and require the Company or the
Employer to apply those funds to the purchase of Shares. Any Eligible Employee who has withdrawn from the Plan may, however, re-enroll in the Plan as of the next subsequent Enrollment Date, if any, in accordance with Section 4.2. 

 

	8.2	Termination of Participation 

Participation in the Plan terminates immediately on the date on which a Participant ceases to be employed by the Company or the Employer for any reason
whatsoever or otherwise ceases to be an Eligible Employee, and all funds then accumulated in the Participant’s Account shall not be used to purchase Shares, but shall instead be distributed to the Participant as soon as administratively
feasible. 
  

	8.3	Leaves of Absence 

 If a Participant takes
a leave of absence, such Participant shall have the right, in accordance with procedures prescribed by the Committee, to elect to withdraw from the Plan in accordance with Section 8.1. To the extent determined by the Committee or required by
Section 423 of the Code, certain leaves of absence may be treated as cessations of employment for purposes of the Plan. 

  
 US-5

 SECTION 9. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, 

DISSOLUTION, LIQUIDATION, MERGER OR SALE OF ASSETS 
  

	9.1	Adjustments Upon Changes in Capitalization 

Subject to any required action by the stockholders of the Company, the right to purchase Shares covered by a current Offering Period and the number of
Shares which have been authorized for issuance under the Plan for any future Offering Period, the maximum number of Shares each Participant may purchase each Offering or Purchase Period (pursuant to Section 5.3 hereof), as well as the price per
Share and the number of Shares covered by each right under the Plan which have not yet been purchased shall be proportionately adjusted in the sole discretion of the Committee for any increase or decrease in the number of issued Shares resulting
from a stock split, reverse stock split, stock dividend, extraordinary cash dividend, combination or reclassification of the Common Stock, or recapitalization, reorganization, consolidation, split-up, spin-off, or any other increase or decrease in
the number of Shares effected without receipt of consideration by the Company. Except as expressly provided otherwise by the Committee, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares. 
  

	9.2	Adjustment Upon Dissolution, Liquidation, Merger or Sale of Assets 

 Without limitation on the preceding provisions, in the event of any dissolution, liquidation, merger, consolidation, sale of all or substantially all of the Company’s outstanding voting securities,
sale, lease, exchange or other transfer of all or substantially all of the Company’s assets, or any similar transaction as determined by the Committee in its sole discretion, the Committee may make such adjustment it deems appropriate to
prevent dilution or enlargement of rights in the number and class of Shares which may be delivered under Section 12, in the number, class of or price of Shares available for purchase under the Plan and in the number of Shares which a
Participant is entitled to purchase and any other adjustments it deems appropriate. Without limiting the Committee’s authority under the Plan, in the event of any such transaction, the Committee may elect to have the options hereunder assumed
or such options substituted by a successor entity, to terminate all outstanding options either prior to their expiration or upon completion of the purchase of Shares on the next Purchase Date, to shorten the Offering Period by setting a new Purchase
Date, or to take such other action deemed appropriate by the Committee. 
 SECTION 10. DESIGNATION OF BENEFICIARY

 Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or
successively) to whom the amount in his or her Account is to be paid in case of his or her death before he or she receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a
form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during the Participant’s lifetime. In the absence of any such designation, any Account balance remaining unpaid at the
Participant’s death shall be paid to the Participant’s estate. 

  
 US-6

 SECTION 11. ADMINISTRATION 

 

	11.1	Administration by Committee 

 The Plan
shall be administered by the Committee. The Committee shall have the authority to delegate duties to officers, directors or employees of the Company. 
  

	11.2	Authority of Committee 

 The Committee
shall have the full and exclusive discretionary authority to construe and interpret the Plan and options granted under it; to establish, amend, and revoke rules and regulations for administration of the Plan (including, without limitation, the
determination and change of Offering Periods, Purchase Periods and payment procedures, the requirement that Shares be held by a specified broker, and the establishment of the exchange ratio applicable to amounts withheld in a currency other than
U.S. dollars); to determine all questions of eligibility, disputed claims and policy that may arise in the administration of the Plan; to make any changes to the Plan or its operations to reduce or eliminate any unfavorable legal, accounting or
other consequences to the extent deemed appropriate by the Committee; and, generally, to exercise such powers and perform such acts as the Committee deems necessary or expedient to promote the best interests of the Company, including, but not
limited to, designating from time to time which Subsidiaries of the Company shall be part of the Employer. The Committee’s determinations as to the interpretation and operation of the Plan shall be final and conclusive and each action of the
Committee shall be binding on all persons. 
 In exercising the powers described in the foregoing paragraph, the Committee may adopt special or
different rules for the operation of the Plan including, but not limited to, rules which allow employees of any foreign Subsidiary to participate in, and enjoy the tax benefits offered by, the Plan; provided, however, that such rules shall not
result in any grantees of options having different rights and/or privileges under the Plan in violation of Section 423 of the Code nor otherwise cause the Plan to fail to satisfy the requirements of Section 423 of the Code and the
regulations thereunder. 
  

	11.3	Administrative Modifications 

 The Plan
provisions relating to the administration of the Plan may be modified by the Committee from time to time as may be desirable to satisfy any requirements of or under the federal securities and/or other applicable laws of the United States, to obtain
any exemption under such laws, or to reduce or eliminate any unfavorable legal, accounting or other consequences or for any other purpose deemed appropriate by the Committee. 

  
 US-7

 SECTION 12. NUMBER OF SHARES 
 Subject to adjustment as set forth in Section 9, the number of Shares reserved for sale and authorized for issuance pursuant to the 2012 Employee Stock Purchase Plan is: 

(a) 1 million shares; plus 
 (b) an
annual increase to be added as of the first day of each fiscal year of the Company equal to the least of (i) 1.25% of the outstanding Common Stock on a fully diluted basis (including the effect of shares of Common Stock issuable pursuant to
outstanding warrants, options and similar rights and conversion of any outstanding securities convertible into Common Stock as of the last day of the Company’s immediately preceding fiscal year, (ii) 550,000 shares of Common Stock, and
(iii) a lesser amount determined by the Board; provided that any shares from any such increases in previous years that are not actually issued shall continue to be available for issuance under the 2012 Employee Stock Purchase Plan. 

Accordingly, the number of Shares authorized for issuance pursuant to the Plan is the number of Shares specified above less the number of Shares issued
pursuant to the M/A-COM Technology Solutions Holdings, Inc. International Employee Stock Purchase Plan. If any option granted under the Plan shall for any reason terminate without having been exercised, the Shares not purchased under such option
shall again become available for issuance under the 2012 Employee Stock Purchase Plan. If on a given Purchase Date, the number of Shares with respect to which options are to be exercised exceeds the number of Shares then available under the Plan,
the Committee shall make a pro rata allocation of the Shares remaining available for purchase in as uniform a manner as shall be practical and as it shall determine to be equitable. 

SECTION 13. MISCELLANEOUS 
  

	13.1	Restrictions on Transfer 

 Options granted
under the Plan to a Participant may not be exercised during the Participant’s lifetime other than by the Participant. Neither amounts credited to a Participant’s Account nor any rights with respect to the exercise of an option or to
receive stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the Participant other than by will or the laws of descent and distribution or by a beneficiary designation as permitted by Section 10.
Any such attempted assignment, transfer, pledge, or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from the Plan in accordance with Section 8.1. 

 

	13.2	Administrative Assistance 

 If the
Committee in its discretion so elects, it may retain a brokerage firm, bank, or other financial institution to assist in the purchase of Shares, delivery of reports, or other administrative aspects of the Plan. If the Committee so elects, each
Participant shall (unless prohibited by applicable law) be deemed upon enrollment in the Plan to have authorized the 

  
 US-8

 
establishment of an account on his or her behalf at such institution. Shares purchased by a Participant under the Plan shall be held in the Account in the Participant’s name, or if the
Participant so indicates in the enrollment form, in the Participant’s name together with the name of his or her spouse in joint tenancy with right of survivorship or spousal community property, or in certain forms of trust approved by the
Committee. 
  

	13.3	Treatment of Non-U.S. Participants 

Participants who are employed by non-U.S. Designated Subsidiaries, who are paid in foreign currency, and who contribute foreign currency to the Plan
through contributions or payroll deductions will have such contributions converted to U.S. dollars. The exchange rate and method for such conversion will be determined as prescribed by the Committee. In no event will any procedure implemented for
dealing with exchange rate fluctuations that may occur during an Offering Period result in a purchase price below the Purchase Price permitted under the Plan. Each Participant shall bear the risk of any currency exchange fluctuations (if applicable)
between the date on which any Participant contributions are converted to U.S. dollars and the following Purchase Date. 
  

	13.4	Withholding 

 The Company or any Employer
shall have the power and the right to deduct or withhold, or require a Participant to remit to the Company or any member of the Employer, an amount sufficient to satisfy federal, state and local taxes, domestic or foreign, required by law or
regulation to be withheld with respect to any taxable event arising as a result of the Plan. 
  

	13.5	Equal Rights and Privileges 

 All Eligible
Employees shall have equal rights and privileges with respect to the Plan so that the Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 or any successor provision of the Code and the related
regulations. Notwithstanding the express terms of the Plan, any provision of the Plan which is inconsistent with Section 423 or any successor provision of the Code shall without further act or amendment by the Company or the Committee be
reformed to comply with the requirements of Section 423 of the Code. This Section 13.5 shall take precedence over all other provisions in the Plan. 
  

	13.6	Applicable Law 

 The Plan shall be
governed by the substantive laws (excluding the conflict of laws rules) of the State of Delaware. 
  

	13.7	Amendment and Termination 

 The Board may
amend, alter or terminate the Plan at any time; provided, however, that (a) the Plan may not be amended in a way that will cause rights issued under the Plan to fail to meet the requirements of Section 423 of the Code and (b) no
amendment that would amend or modify the Plan in a manner requiring stockholder approval under Section 423 of the Code or the requirements of any securities exchange on which the Shares are traded shall be effective unless such stockholder
approval is obtained. In addition, the Committee may amend the Plan as provided in Section 11.3, subject to the conditions set forth in this Section 13.7. 

  
 US-9

 If the Plan is terminated prior to the date set forth in Section 13.8, the Committee may elect to
terminate all outstanding options either prior to their expiration or upon completion of the purchase of Shares on the next Purchase Date, or may elect to permit options to expire in accordance with their terms (and participation to continue through
such expiration dates). If the options are terminated prior to expiration, all funds accumulated in Participants’ Accounts as of the date the options are terminated shall be returned to the Participants as soon as administratively feasible.

  

	13.8	Term of Plan 

 Unless sooner terminated by
the Board, the Plan shall automatically terminate on the tenth anniversary of the earlier of (a) the date the Board adopts the Plan and (b) the date the stockholders approve the Plan. After the Plan terminates in accordance with the
foregoing sentence, no future options may be granted under the Plan, but options previously granted shall remain outstanding in accordance with their terms and conditions and the Plan’s terms and conditions. 

 

	13.9	No Right of Employment 

 Neither the grant
nor the exercise of any rights to purchase Shares under the Plan nor anything in the Plan shall impose upon the Company or any member of the Employer any obligation to employ or continue to employ any Employee. The right of the Company or a member
of the Employer to terminate any Employee shall not be diminished or affected because any rights to purchase Shares have been granted to such Employee. 
  

	13.10	Rights as Stockholder 

 No Participant
shall have any rights as stockholder unless and until Shares have been issued to him or her. 
  

	13.11	Governmental Regulation 

 The
Company’s obligation to sell and deliver Shares under the Plan is subject to the approval of any governmental authority required in connection with the authorization, issuance, or sale of such Shares. 

 

	13.12	Gender 

 When used herein, masculine terms
shall be deemed to include the feminine, except when the context indicates to the contrary. 

  
 US-10

	13.13	Condition for Participation 

 As a
condition to participation in the Plan, Eligible Employees agree to be bound by the terms of the Plan (including, without limitation, the notification and holding requirements of Section 7.5) and the determinations of the Committee.

otherwise determined appropriate by the Committee, Employees whose customary employment is twenty (20) hours or less per week are not eligible to participate in the Plan. 
 SECTION 4. ENROLLMENT 
  

	4.1	First Offering Period 

 Any Eligible
Employee immediately prior to the first Offering Period under the Plan will be automatically enrolled in the first Offering Period. An Eligible Employee will be eligible to continue participation in the first Offering Period only if such individual
completes and signs an enrollment election form (or completes such other enrollment procedure established by the Committee) and submits such enrollment election to the Company (a) no earlier than the effective date of the Form S-8 registration
statement with respect to the issuance of Shares under the 2012 Employee Stock Purchase Plan and (b) no later than ten (10) business days following the effective date of such S-8 registration statement or such other period of time as the
Committee may determine (the “Enrollment Window”). An Eligible Employee’s failure to submit the enrollment election form (or complete such other enrollment procedure permitted by the Committee) during the Enrollment Window will
result in the automatic termination of such individual’s participation in the first Offering Period. 
  

	4.2	Subsequent Offering Periods 

 Subsequent
to commencement of the first Offering Period, any Eligible Employee may enroll in the Plan for an Offering Period by completing and signing an enrollment election form or 

  
 INT-1

 
by such other means as the Committee shall prescribe and submitting such enrollment election to the Company in accordance with procedures established by the Committee on or before the Cut-Off
Date with respect to such future Offering Period. 
  

	4.3	Continuing Effectiveness of Enrollment Election 

 Unless otherwise determined by the Committee, the enrollment election and the designated rate of payroll deduction shall continue for future Offering Periods unless the Participant changes or cancels, in
accordance with procedures established by the Committee, the enrollment election or designated rate of payroll deduction prior to the Cut-Off Date with respect to a future Offering Period or elects to withdraw from the Plan in accordance with
Section 8.1. 
 SECTION 5. GRANT OF OPTIONS ON ENROLLMENT 

 

	5.1	Option Grant 

 Enrollment by an Eligible
Employee in the Plan as of an Enrollment Date will constitute the grant by the Company to such Participant of an option on such Enrollment Date to purchase Shares from the Company pursuant to the Plan. 

 

	5.2	Option Expiration 

 An option granted to a
Participant pursuant to the Plan shall expire, if not terminated for any reason first, on the earliest to occur of: (a) the end of the Offering Period in which such option was granted; (b) the completion of the purchase of Shares under the
option under Section 7; or (c) the date on which participation of such Participant in the Plan terminates for any reason. 
  

	5.3	Purchase of Shares 

 An option granted to
a Participant under the Plan shall give the Participant a right to purchase on a Purchase Date the largest number of whole Shares, as determined by the Committee, which the funds accumulated in the Participant’s Account as of such Purchase Date
will purchase at the applicable Purchase Price; provided, however, that, unless the Committee determines otherwise for a future Offering Period or Purchase Period, no Participant may purchase during a Purchase Period more than 625 Shares, subject to
adjustment as provided in the Plan. Any payment made by a Participant in excess of the foregoing limitation shall be returned to the Participant in accordance with procedures established by the Committee. 

SECTION 6. PAYMENT 
 (a)
The Committee may designate the time and manner for payment of Shares to be purchased during the Purchase Period, including, but not limited to, through payroll deductions from Eligible Compensation, the terms and conditions of which are designated
by the Committee; provided, however, that unless the Committee determines otherwise for a future Purchase Period, any payroll deductions must be in one percent (1%) increments 

  
 INT-2

 
comprising not less than one percent (1%) and not more than fifteen percent (15%) of a Participant’s Eligible Compensation received on each pay day during the Purchase Period.
Payment amounts shall be credited on a bookkeeping basis to a Participant’s Account under the Plan. All payment amounts may be used by the Company for any purpose and the Company shall have no obligation to segregate such funds. No interest
accrues on payments by Participants. 
 (b) Any payroll deductions for a Participant shall commence on the first pay day following the
Enrollment Date and will end on the last pay day prior to the Purchase Date; provided, however, that for the first Offering Period, payroll deductions will commence on the first pay day on or following the end of the Enrollment Window. 

SECTION 7. PURCHASE OF SHARES 
  

	7.1	Option Exercise 

 Any option held by a
Participant that was granted under the Plan and that remains outstanding as of a Purchase Date shall be deemed to have been exercised on such Purchase Date for the number of whole Shares, as determined by the Committee, that the funds accumulated in
the Participant’s Account as of the Purchase Date will purchase at the applicable Purchase Price (but not in excess of the number of Shares for which options have been granted to the Participant pursuant to Section 5.3). Options for other
Shares for which options have been granted that are not purchased on the last Purchase Date during the Offering Period shall terminate. Shares shall not be issued with respect to an option unless the exercise of such option and the issuance and
delivery of such Shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the rules and
regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed. As a condition to the exercise of an option, the Committee may require the person exercising such option to represent and
warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares. 
  

	7.2	Refund of Excess Amount 

 If, after a
Participant’s exercise of an option under Section 7.1, an amount remains credited to the Participant’s Account as of a Purchase Date (including after return of any amount pursuant to Section 5.3), then the remaining amount shall
be (a) if no further Purchase Periods are immediately contemplated by the Committee, distributed to the Participant as soon as administratively feasible, or (b) if another Purchase Period is contemplated by the Committee, carried forward
in the Account for application to the purchase of Shares on the next following Purchase Date. 
  

	7.3	Employees of Subsidiary 

 In the case of
Participants employed by a Designated Subsidiary, the Committee may provide for Shares to be sold through the Subsidiary to such Participants. 

  
 INT-3

	7.4	Pro Rata Allocation 

 If the total number
of Shares for which options are or could be exercised on any Purchase Date in accordance with this Section 7, when aggregated with all Shares for which options have been previously exercised under the Plan, exceeds the maximum number of Shares
reserved in Section 12, the Company may, in accordance with Section 12, allocate the Shares available for delivery and distribution in the ratio that the balance in each Participant’s Account bears to the aggregate balances of all
Participants’ Accounts, and the remaining balance of the amount credited to the Account of each Participant under the Plan shall be returned to him or her as promptly as possible. 

SECTION 8. WITHDRAWAL FROM THE PLAN, TERMINATION 
 OF EMPLOYMENT, AND LEAVES OF ABSENCE 
  

	8.1	Withdrawal From the Plan 

 A Participant
may withdraw all funds accumulated in the Participant’s Account from the Plan during any Purchase Period by delivering a notice of withdrawal to the Company or the Employer (in a manner prescribed by the Committee) at any time up to but not
including the ten (10) days prior to the Purchase Date for such Purchase Period, or by such longer time period in advance of the Purchase Date as the Committee may require. If notice of complete withdrawal from the Plan as described in the
preceding sentence is timely received, the Company or the Employer will cease the Participant’s payroll withholding for the Plan and all funds then accumulated in the Participant’s Account shall not be used to purchase Shares, but shall
instead be distributed to the Participant as soon as administratively feasible. An Employee who has withdrawn from a Purchase Period may not return funds to the Company or the Employer during that Purchase Period and require the Company or the
Employer to apply those funds to the purchase of Shares. Any Eligible Employee who has withdrawn from the Plan may, however, re-enroll in the Plan as of the next subsequent Enrollment Date, if any, in accordance with Section 4.2. 

 

	8.2	Termination of Participation 

Participation in the Plan terminates immediately on the date on which a Participant ceases to be employed by the Company or the Employer for any reason
whatsoever or otherwise ceases to be an Eligible Employee, and all funds then accumulated in the Participant’s Account shall not be used to purchase Shares, but shall instead be distributed to the Participant as soon as administratively
feasible. 
  

	8.3	Leaves of Absence 

 If a Participant takes
a leave of absence, such Participant shall have the right, in accordance with procedures prescribed by the Committee, to elect to withdraw from the Plan in accordance with Section 8.1. To the extent determined by the Committee, certain leaves
of absence may be treated as cessations of employment for purposes of the Plan. 

  
 INT-4

 SECTION 9. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, 

DISSOLUTION, LIQUIDATION, MERGER OR SALE OF ASSETS 
  

	9.1	Adjustments Upon Changes in Capitalization 

Subject to any required action by the stockholders of the Company, the right to purchase Shares covered by a current Offering Period and the number of
Shares which have been authorized for issuance under the Plan for any future Offering Period, the maximum number of Shares each Participant may purchase each Offering or Purchase Period (pursuant to Section 5.3 hereof), as well as the price per
Share and the number of Shares covered by each right under the Plan which have not yet been purchased shall be proportionately adjusted in the sole discretion of the Committee for any increase or decrease in the number of issued Shares resulting
from a stock split, reverse stock split, stock dividend, extraordinary cash dividend, combination or reclassification of the Common Stock, or recapitalization, reorganization, consolidation, split-up, spin-off, or any other increase or decrease in
the number of Shares effected without receipt of consideration by the Company. Except as expressly provided otherwise by the Committee, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares. 
  

	9.2	Adjustment Upon Dissolution, Liquidation, Merger or Sale of Assets 

 Without limitation on the preceding provisions, in the event of any dissolution, liquidation, merger, consolidation, sale of all or substantially all of the Company’s outstanding voting securities,
sale, lease, exchange or other transfer of all or substantially all of the Company’s assets, or any similar transaction as determined by the Committee in its sole discretion, the Committee may make such adjustment it deems appropriate to
prevent dilution or enlargement of rights in the number and class of Shares which may be delivered under Section 12, in the number, class of or price of Shares available for purchase under the Plan and in the number of Shares which a
Participant is entitled to purchase and any other adjustments it deems appropriate. Without limiting the Committee’s authority under the Plan, in the event of any such transaction, the Committee may elect to have the options hereunder assumed
or such options substituted by a successor entity, to terminate all outstanding options either prior to their expiration or upon completion of the purchase of Shares on the next Purchase Date, to shorten the Offering Period by setting a new Purchase
Date, or to take such other action deemed appropriate by the Committee. 
 SECTION 10. DESIGNATION OF BENEFICIARY

 Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or
successively) to whom the amount in his or her Account is to be paid in case of his or her death before he or she receives any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a
form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during the Participant’s lifetime. In the absence of any such designation, any Account balance remaining unpaid at the
Participant’s death shall be paid to the Participant’s estate. 

  
 INT-5

 SECTION 11. ADMINISTRATION 

 

	11.1	Administration by Committee 

 The Plan
shall be administered by the Committee. The Committee shall have the authority to delegate duties to officers, directors or employees of the Company. 
  

	11.2	Authority of Committee 

 The Committee
shall have the full and exclusive discretionary authority to construe and interpret the Plan and options granted under it; to establish, amend, and revoke rules and regulations for administration of the Plan (including, without limitation, the
determination and change of Offering Periods, Purchase Periods and payment procedures, the requirement that Shares be held by a specified broker, and the establishment of the exchange ratio applicable to amounts withheld in a currency other than
U.S. dollars); to determine all questions of eligibility, disputed claims and policy that may arise in the administration of the Plan; to make any changes to the Plan or its operations to reduce or eliminate any unfavorable legal, accounting or
other consequences to the extent deemed appropriate by the Committee; and, generally, to exercise such powers and perform such acts as the Committee deems necessary or expedient to promote the best interests of the Company, including, but not
limited to, designating from time to time which Subsidiaries of the Company shall be part of the Employer. The Committee’s determinations as to the interpretation and operation of the Plan shall be final and conclusive and each action of the
Committee shall be binding on all persons. The Committee may adopt special or different rules for the operation of the Plan for different Participants, including, but not limited to, rules designed to accommodate the practices of the applicable
jurisdiction. 
  

	11.3	Administrative Modifications 

 The Plan
provisions relating to the administration of the Plan may be modified by the Committee from time to time as may be desirable to satisfy any requirements of or under the securities or other applicable laws of the United States or other jurisdiction,
to obtain any exemption under such laws, or to reduce or eliminate any unfavorable legal, accounting or other consequences or for any other purpose deemed appropriate by the Committee. 

SECTION 12. NUMBER OF SHARES 
 Subject to adjustment as set forth in Section 9, the number of Shares reserved for sale and authorized for issuance pursuant to the 2012 Employee Stock Purchase Plan is: 

(a) 1 million shares; plus 
 (b) an
annual increase to be added as of the first day of each fiscal year of the Company equal to the least of (i) 1.25% of the outstanding Common Stock on a fully diluted basis 

  
 INT-6

 
(including the effect of shares of Common Stock issuable pursuant to outstanding warrants, options and similar rights and conversion of any outstanding securities convertible into Common Stock as
of the last day of the Company’s immediately preceding fiscal year, (ii) 550,000 shares, and (iii) a lesser amount determined by the Board; provided that any shares from any such increases in previous years that are not actually
issued shall continue to be available for issuance under the 2012 Employee Stock Purchase Plan. 
 Accordingly, the number of Shares authorized
for issuance pursuant to the Plan is the number of Shares specified above less the number of Shares issued pursuant to the M/A-COM Technology Solutions Holdings, Inc. U.S. Employee Stock Purchase Plan. If any option granted under the Plan shall for
any reason terminate without having been exercised, the Shares not purchased under such option shall again become available for issuance under the 2012 Employee Stock Purchase Plan. If on a given Purchase Date, the number of Shares with respect to
which options are to be exercised exceeds the number of Shares then available under the Plan, the Committee shall make a pro rata allocation of the Shares remaining available for purchase in as uniform a manner as shall be practical and as it shall
determine to be equitable. 
 SECTION 13. MISCELLANEOUS 

 

	13.1	Restrictions on Transfer 

 Options granted
under the Plan to a Participant may not be exercised during the Participant’s lifetime other than by the Participant. Neither amounts credited to a Participant’s Account nor any rights with respect to the exercise of an option or to
receive stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way by the Participant other than by will or the laws of descent and distribution or by a beneficiary designation as permitted by Section 10.
Any such attempted assignment, transfer, pledge, or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw from the Plan in accordance with Section 8.1. 

 

	13.2	Administrative Assistance 

 If the
Committee in its discretion so elects, it may retain a brokerage firm, bank, or other financial institution to assist in the purchase of Shares, delivery of reports, or other administrative aspects of the Plan. If the Committee so elects, each
Participant shall (unless prohibited by applicable law) be deemed upon enrollment in the Plan to have authorized the establishment of an account on his or her behalf at such institution. Shares purchased by a Participant under the Plan shall be held
in the Account in the Participant’s name, or if the Participant so indicates in the enrollment form, in the Participant’s name together with the name of his or her spouse in joint tenancy with right of survivorship or spousal community
property, or in certain forms of trust approved by the Committee. 
  

	13.3	Treatment of Non-U.S. Participants 

Participants who are employed by non-U.S. Designated Subsidiaries, who are paid in foreign currency, and who contribute foreign currency to the Plan
through contributions or payroll 

  
 INT-7

 
deductions will have such contributions converted to U.S. dollars. The exchange rate and method for such conversion will be determined as prescribed by the Committee. In no event will any
procedure implemented for dealing with exchange rate fluctuations that may occur during an Offering Period result in a purchase price below the Purchase Price permitted under the Plan. Each Participant shall bear the risk of any currency exchange
fluctuations (if applicable) between the date on which any Participant contributions are converted to U.S. dollars and the following Purchase Date. 
  

	13.4	Withholding 

 The Company or any Employer
shall have the power and the right to deduct or withhold, or require a Participant to remit to the Company or any member of the Employer, an amount sufficient to satisfy taxes, domestic or foreign, required by law or regulation to be withheld with
respect to any taxable event arising as a result of the Plan. 
  

	13.5	Applicable Law 

 The Plan shall be
governed by the substantive laws (excluding the conflict of laws rules) of the State of Delaware. 
  

	13.6	Amendment and Termination 

 The Board may
amend, alter, or terminate the Plan at any time; provided, however, that no amendment which would amend or modify the Plan in a manner requiring stockholder approval under the requirements of any securities exchange on which the Shares are traded
shall be effective unless such stockholder approval is obtained. In addition, the Committee may amend the Plan as provided in Section 11.3, subject to the conditions set forth in this Section 13.6. 

If the Plan is terminated prior to the date set forth in Section 13.7, the Committee may elect to terminate all outstanding options either prior to
their expiration or upon completion of the purchase of Shares on the next Purchase Date, or may elect to permit options to expire in accordance with their terms (and participation to continue through such expiration dates). If the options are
terminated prior to expiration, all funds accumulated in Participants’ Accounts as of the date the options are terminated shall be returned to the Participants as soon as administratively feasible. 

 

	13.7	Term of Plan 

 Unless sooner terminated by
the Board, the Plan shall automatically terminate on the tenth anniversary of the earlier of (a) the date the Board adopts the Plan and (b) the date the stockholders approve the Plan. After the Plan terminates in accordance with the
foregoing sentence, no future options may be granted under the Plan, but options previously granted shall remain outstanding in accordance with their terms and conditions and the Plan’s terms and conditions. 

  
 INT-8

	13.8	No Right of Employment 

 Neither the grant
nor the exercise of any rights to purchase Shares under the Plan nor anything in the Plan shall impose upon the Company or any member of the Employer any obligation to employ or continue to employ any Employee. The right of the Company or a member
of the Employer to terminate any Employee shall not be diminished or affected because any rights to purchase Shares have been granted to such Employee. 
  

	13.9	Rights as Stockholder 

 No Participant
shall have any rights as stockholder unless and until Shares have been issued to him or her. 
  

	13.10	Governmental Regulation 

 The
Company’s obligation to sell and deliver Shares under the Plan is subject to the approval of any governmental authority required in connection with the authorization, issuance, or sale of such Shares. 

 

	13.11	Gender 

 When used herein, masculine terms
shall be deemed to include the feminine, except when the context indicates to the contrary. 
  

	13.12	Condition for Participation 

 As a
condition to participation in the Plan, Eligible Employees agree to be bound by the terms of the Plan and the determinations of the Committee.

 M/A-COM Technology Solutions Inc. 

100 Chelmsford Street 
 Lowell, MA 01851 
 July 16, 2009 
 Robert S. Donahue 
 Re: Offer of Employment with M/A-COM Technology Solutions
Inc. 
 Dear Bob: 

On behalf of M/A-COM Technology Solutions Inc., a Delaware corporation (the “Company”), I am pleased to invite you to
join the Company as its Chief Strategy Officer, reporting to me. This is an exempt position and you will be working out of our 100 Chelmsford St., Lowell MA Corporate Headquarters. Subject to the terms and conditions set forth in this letter, the
effective date of your employment will be mutually agreed to in writing at a later date. 
 The terms of this offer of
employment are as follows: 
 1. At-Will Employment. You should be aware that your employment with the Company is for no
specified period and constitutes “at-will” employment. As a result, you are free to terminate your employment at any time, for any reason or for no reason. Similarly, the Company is free to terminate your employment at any time, for any
reason or for no reason. We request that, in the event of a resignation, you give the Company at least two weeks’ notice. 

2. Compensation. The Company will pay you a salary at the rate of $26,041.67 per month payable in accordance with the
Company’s standard payroll policies, including compliance with applicable withholding. The first and last payment by the Company to you will be adjusted, if necessary, to reflect a commencement or termination date other than the first or last
working day of a pay period. You will also be eligible to participate in a Company bonus plan, with a maximum bonus participation potential of up to 50% of your annualized salary per year, based on Company and/or individual performance targets
determined by the Board of Directors from time to time. In addition, as an incentive to join the Company, the Company is pleased to offer you a one-time signing bonus in the amount of $35,000, subject to applicable withholding and payable
concurrently with your first regular paycheck following your start date with the Company in accordance with the Company’s standard payroll policies (the “Signing Bonus”). The Signing Bonus is being paid to you with the
expectation that you will be a long-term contributor to the Company’s success. To the extent that your employment with the 

 
Company terminates within twelve (12) months following your start date for any reason other than your death or the Company terminating your employment other than for “Cause” (as
defined below), you agree to reimburse the Company for the full amount of the Signing Bonus within fifteen (15) days following the date your employment terminates, and further agree that the Company in its sole discretion may (but shall not be
required to) elect to reduce the amount of any severance or other payment otherwise owed to you pursuant to this letter agreement on a dollar for dollar basis to offset in whole or in part the amount you are required to repay under this
Section 2. 
 3. Stock Options. As you may be aware, the Company’s parent, M/A-COM Technology Solutions
Holdings, Inc. (“Parent”), is in the process of setting up a stock option plan to provide certain employees and other service providers with employment incentives. Subject to the adoption of such plan and approval by the
Parent’s Board of Directors in accordance with applicable law, you will be granted: 
 (a) An option
under the plan to purchase six hundred thousand (600,000) shares of Parent’s Common Stock (the “First Option”). One-fifth (1/5th) of the shares subject to the First Option will vest and become exercisable on the first
anniversary of the option grant date and an additional one sixtieth (1/60th) of the total number of such shares will vest on the corresponding day of each month thereafter, or to the extent such a month does not have the corresponding day, on the last day of any such month,
until all the shares are vested, subject to your continued employment with the Company at each such date. 
 (b) An additional
option under the plan to purchase four hundred and fifty thousand (450,000) shares of Parent’s Common Stock (the “Second Option”). All of the shares subject to the Second Option shall vest and become exercisable if and
only if the consolidated annual revenue of Parent and all Parent’s subsidiaries (“Group Revenue”) (less any such revenue attributable to any products, technologies, assets or organizations acquired by Parent or its subsidiaries
after the date hereof, other than revenue attributable to any Included Acquisitions as defined below) meets or exceeds $370,000,000 (the “Revenue Threshold”) for any fiscal year of Parent ending after the date hereof and on or
before December 31, 2012. In the event that Parent divests any line of business between the date hereof and December 31, 2012, then for purposes of this Paragraph 3(b) only, for each fiscal year of Parent ending after the effective date of
such divestment and on or before December 31, 2012: (i) from and after the effective date of such divestment, the otherwise applicable Revenue Threshold shall be deemed to be reduced, dollar for dollar, by the amount of revenue such
business line contributed to Group Revenue for its most recently completed fiscal year prior to the effective date of such divestiture, and (ii) from and after the effective date of such divestment, in measuring the Group Revenue for any such
fiscal year for purposes of determining whether a vesting event occurs hereunder, the parties agree to exclude from such calculation (and reduce the otherwise applicable Group Revenue by the amount of) any and all revenue attributable to the line of
business so divested. Included Acquisitions as used herein means the next $25,000,000 of revenue attributable to acquisitions made by Parent or its subsidiaries following the date of this letter agreement, as measured by the trailing twelve month
revenues associated with each such acquired business or group of assets at the time each was acquired. In the event that the trailing twelve month revenue for any Included Acquisition, when aggregated with the trailing twelve month revenue for any
prior Included Acquisitions, would exceed the $25,000,000 limit noted above, then the amount of post-

 
acquisition revenue attributable to that Included Acquisition that may be counted toward achievement of the Revenue Threshold in any period in accordance with this paragraph shall be limited to
the percentage of such post-acquisition revenue attributable to such Included Acquisition that (A) the portion of the trailing twelve month revenue for such Included Acquisition which (considered together with the trailing twelve month revenue
for any prior Included Acquisitions) is not in excess of the $25,000,000 limit represents of (B) the total trailing twelve month revenue for such Included Acquisition. For the avoidance of doubt, the trailing twelve month revenue of any prior
Included Acquisitions shall not be included in the numerator of the above-described fraction, but rather used as a reference point for determining such numerator. 
 (c) An additional option under the plan to purchase four hundred and fifty thousand (450,000) shares of Parent’s Common Stock (the “Third Option”). All of the shares subject to
the Third Option shall vest and become exercisable if and only if the consolidated annual earnings before income tax of Parent and all Parent’s subsidiaries, calculated to exclude any (x) gains or losses from the sale, exchange, transfer
or other disposition of property or assets not in the ordinary course of business of Parent and such subsidiaries, and (y) other extraordinary gains or losses of Parent and such subsidiaries (“Group EBIT”) exceeds the greater
of (i) $70,000,000 (the “EBIT Dollar Threshold”) and (ii) twenty-five percent (25%) of Group Revenue for any fiscal year of Parent ending after the date hereof and on or before December 31, 2012. In the event
that Parent divests any line of business between the date hereof and December 31, 2012, then for purposes of this Paragraph 3(c) only, from and after the effective date of such divestment, (A) the otherwise applicable EBIT Dollar Threshold
shall be deemed to be, as applicable, either reduced, dollar for dollar, by any amount of Group EBIT such business line contributed to overall Group EBIT for Parent’s most recently completed fiscal year prior to the effective date of such
divestiture, or increased, dollar for dollar, by any amount of negative Group EBIT such business line contributed to overall Group EBIT for Parent’s most recently completed fiscal year prior to the effective date of such divestiture, and
(B) in measuring Parent’s performance against the EBIT Dollar Threshold for any fiscal year ending on or after the date of such divestment, the parties agree to exclude from such calculation any positive or negative Group EBIT contributed
by such business line during such fiscal year (and therefore to reduce the otherwise applicable Group EBIT for such purpose by the amount of any such positive contribution or increase the otherwise applicable Group EBIT by the amount of any such
negative contribution, as applicable). 
 Each of the three options will have a per share exercise price equal to the fair
market value of a share of Parent Common Stock on the date the option is granted, as determined by the Parent Board of Directors. Each option grant shall be subject to the terms and conditions of the Parent stock option plan and related stock option
agreement. No right to any stock is earned or accrued under any such option until such time as vesting occurs, nor does the grant confer any right to continued vesting or employment. 

4. Severance. 
 (a) Our at-will relationship notwithstanding, if the Company terminates your employment with the Company other than for “Cause” (as defined below) or you resign for “Good Reason” (as
defined below) (each an “Involuntary Termination”), and in either case you 

 
sign, deliver to the Company and do not revoke a general release of claims in the Company’s favor in a form and substance acceptable to the Company (the “Release”), then you
shall be entitled to receive as severance pay continuation of your monthly salary, as then in effect and payable in accordance with the Company’s standard payroll policies, including compliance with applicable withholding, for a period of six
(6) months (or alternatively, if such Involuntary Termination occurs within six (6) months following a Change in Control (as defined below), for a period of twelve (12) months) following the date your employment with the Company
terminated (either such period, as applicable, is hereinafter referred to as the “Severance Period”). 
 (b)
Subject to the same conditions applicable to the receipt of any severance payments otherwise payable during any Severance Period as set forth in Section 4(a), to the extent that you or any of your dependents may be covered under the terms of
any medical and dental plans of the Company immediately prior to the termination of your employment, the Company will provide you with reimbursement for premiums paid for the continuation of such benefits for you and those dependents for the same or
equivalent coverages through the end of the Severance Period. The Company is under no obligation to provide reimbursement for special coverages for you that would not be covered by the plans applicable to employees generally. The reimbursement
payable to you pursuant to this paragraph shall be reduced by the amount equal to the contributions required from time to time from other employees for equivalent coverages under the Company’s medical or dental plans. If and to the extent that
you or any of your dependents is or becomes eligible to participate in a medical, dental or other health insurance plan of another employer during the Severance Period, then the reimbursement benefit provided by this paragraph shall be eliminated or
commensurately diminished. 
 (c) Subject to the same conditions applicable to the receipt of any severance payments otherwise
payable during any Severance Period as set forth in Section 4(a), if such Involuntary Termination occurs within six (6) months following a Change in Control (as defined below), then effective as of immediately prior to the effectiveness of
such Involuntary Termination, you shall be given six (6) months’ accelerated vesting credit against your First Option only (meaning that your final total of vested shares as to this First Option shall be equivalent to the number of such
shares that would have been vested under the normal vesting schedule of the First Option had you remained employed with the Company through the date that is six (6) months following the effective date of such Involuntary Termination).

 (d) You hereby agree that the severance benefits provided for in this Section 4 are the only severance benefits to which
you may be entitled in the event of the termination of your employment with the Company, and that such benefits will be reduced dollar for dollar by any severance-related amount the Company is required to pay you by law, corporate policy or other
source that would otherwise duplicate any portion of the severance benefits provided herein. 
 As used herein,
“Cause” shall mean (i) an act of dishonesty made by you in connection with your responsibilities as an employee; (ii) your conviction of, or plea of nolo contendere to, a felony, or commission of an act of moral turpitude;
(iii) your gross misconduct; or (iv) your (a) material failure to discharge your employment duties or (b) a material breach of this offer letter or the ECIA (as defined below), in each case after you have received a written
demand for performance from the Company (or notice of misconduct, where applicable) specifying the breach of employment duties and your failure to cure such breach (where such breach is curable) within thirty (30) days of the date of such
notice from the Company. 

 As used herein, “Good Reason” shall mean your resignation within thirty
(30) days following the expiration of any Company cure period (discussed below) following the occurrence of one or more of the following, without your consent: (i) the assignment to you of any duties, or the reduction of your duties,
either of which results in a material diminution of your authority, duties, or responsibilities with the Company in effect immediately prior to such assignment, or the removal of you from such position and responsibilities; provided, however, that a
reduction in duties, position or responsibilities solely by virtue of the Company being acquired and made part of a larger entity, whether as a subsidiary, business unit or otherwise (as, for example, when the Chief Financial Officer of the Company
remains the Chief Financial Officer of the Company following a Change in Control where the Company becomes a wholly owned subsidiary of the acquiror, but is not made the Chief Financial Officer of the acquiring corporation) will not constitute
“Good Reason;” (ii) a material reduction of your base salary (in other words, a reduction of more than twenty percent of your base salary in any one year); (iii) a material change in the geographic location at which you must
perform services (in other words, the relocation of you to a facility that is more than fifty (50) miles from your current work location); and (iv) the failure of the Company to obtain assumption of this agreement by any successor. You
agree you will not resign for Good Reason without first providing the Company with written notice of the acts or omissions constituting the grounds for “Good Reason” within thirty (30) days of the initial existence of the grounds for
“Good Reason” and a reasonable cure period of not less than thirty (30) days following the date of such notice. 

As used herein, a “Change in Control” shall be deemed to occur if any of the following occur with respect to Parent
following the date we each execute this Agreement: 
 (1) Any person or entity first acquires securities of
Parent representing more than 50% of the combined voting power of Parent’s then outstanding securities entitled to vote generally in the election of directors (“Voting Securities”), provided, however, that the following shall not
constitute a Change in Control pursuant to this paragraph (g)(1): 
 (A) any acquisition or beneficial ownership
by Parent or a subsidiary or affiliate, 
 (B) any acquisition or beneficial ownership by any employee benefit
plan (or related trust) sponsored or maintained by Parent or one or more of its subsidiaries or affiliates, 

(C) any acquisition or beneficial ownership by any person or entity with respect to which, immediately following such
acquisition, more than 50% of the combined voting power of Parent’s then outstanding Voting Securities is then beneficially owned, directly or indirectly, by persons who beneficially owned more than 50% of the Voting Securities immediately
prior to such acquisition, or 
 (D) any sale of stock by Parent for capital raising purposes (including, without
limitation, any initial public offering of Parent’s securities); 

 (2) A majority of the members of the Board of Directors of Parent shall not
be Continuing Directors. “Continuing Directors” shall mean: (A) individuals who, on the date hereof, are directors of Parent, (B) individuals elected as directors of Parent subsequent to the date hereof for whose election proxies
shall have been solicited by the Board or who shall have been recommended for election by the Board, (C) individuals elected as directors of Parent subsequent to the date hereof pursuant to a nomination or board representation right of
preferred shareholders of Parent, or (D) any individual elected or appointed by the Board or stockholders to fill vacancies on the Board caused by death or resignation (but not by removal) or to fill newly created directorships; 

(3) Consummation of a reorganization, merger or consolidation of Parent or a statutory exchange of outstanding Voting
Securities, unless, immediately following such transaction, more than 50% of the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors of Parent or the corporation that is the issuer
of the securities held by the shareholders of Parent after such transaction is beneficially owned, directly or indirectly, by persons who beneficially owned more than 50% of the Voting Securities of Parent immediately prior to such transaction; or

 (4) Consummation of (x) a complete liquidation or dissolution of Parent or (y) the sale or other
disposition of all or substantially all of the assets of Parent (in one or a series of related transactions), other than to a subsidiary, affiliate or another entity with respect to which, immediately following such sale or other disposition, more
than 50% of the combined voting power of the then outstanding voting securities of such entity entitled to vote generally in the election of directors is then beneficially owned, directly or indirectly, by persons who were the beneficial owners of
more than 50% of the Voting Securities of Parent immediately prior to such sale or other disposition. 
 5. Post-Termination
Restrictions. 
 (a) Non-Competition. You acknowledge that, as an employee of the Company, you will
have access to valuable, proprietary trade secret and other confidential information of the Company in connection with this letter agreement. You acknowledge that such valuable proprietary and confidential information is developed and acquired by
the Company on an ongoing basis and you will receive the benefit of access to new and unique information on a continuing basis, and that such information is worthy of protection. To further ensure the confidentiality of the Company’s trade
secrets and other proprietary information, during the time you are employed by the Company and also during any Severance Period, you agree that you shall not directly or indirectly (whether for compensation or otherwise), alone or as a partner,
associate, agent, principal, trustee, consultant, co-venturer, creditor, owner (excepting not more than 1% passive stockholdings for investment purposes in securities of publicly held and traded companies), representative, or in any other capacity,
engage in, take any action constituting or in furtherance of, participate with or become interested in or associated with any person, firm, partnership, corporation or other entity which is or intends to be in competition with the Company in those
portions of the Company’s business in which you were involved during your tenure of employment with the Company. You further understand and agree to be bound by the provisions of this Section 5 because you are employed in a position of
trust and responsibility and have access and will have access to current as well as future confidential and proprietary information, and this covenant is necessary to prevent the inevitable disclosure of confidential and proprietary information
should you accept employment in violation of such provisions. 

 (b) Non-Solicitation. During the time you are employed by the Company
and also during any Severance Period, you agree that you shall not directly or indirectly (whether for compensation or otherwise), alone or together with others, influence or attempt to influence customers or suppliers of the Company or any of its
present or future subsidiaries or affiliates, either directly or indirectly, to divert their business to any individual, partnership, firm, corporation or other entity then in competition with the business of the Company or any subsidiary or
affiliate of the Company. 
 (c) Consideration; Tolling, Scope and Reasonableness. You agree that in
addition to the other good and valuable consideration you are receiving for the covenants contained in this Section 5 as recited above, any severance amount payable to you by the Company in respect of any Severance Period hereunder constitutes
further consideration for these covenants. You agree that the periods of time during which you are prohibited by Sections 5(b) and (c) hereof from engaging in such business practices shall be extended by any length of time during which you are
in breach of any of such covenants. The covenants contained in this Section 5 shall apply in any country or jurisdiction where the Company and its affiliates had offices or shipped product during the term of your employment with the Company.
You and the Company agree that the time, scope and geographic limitations and other particulars of the foregoing covenants are appropriate and reasonable when considered in light of the nature and extent of the business conducted by the Company and
your role in the Company. 
 (d) Remedies. If you commit a breach, or threaten to commit a breach, of any
of the provisions of this Section 5, the Company shall have the following rights and remedies, in addition to any and all others rights and remedies of law or in equity, each of which shall be independent of the other and severally enforceable:
(i) the right to have the provisions of this letter agreement specifically enforced by any court having equity jurisdiction, including the right to a restraining order, an injunction or other equitable relief, it being acknowledged and agreed
that any such breach or threatened breach will cause irreparable injury to the Company and that money damages will not provide an adequate remedy to it; and (ii) the right and remedy to require you to account for and pay over to the Company all
compensation, profits, monies, accruals, increments or other benefits (hereinafter collectively the “Benefits”) derived or received, directly or indirectly, by you as a result of any transactions constituting a breach of any of the
provisions of this letter agreement, and you hereby agree to account for and pay over any such Benefits to the Company. 
 6.
Benefits. During the term of your employment, you will be eligible, provided that you meet the eligibility requirements of the relevant plans and policies, for the Company’s standard employee benefits applicable to employees at your
level, including health, dental, vision, life, short and long-term disability insurance. The Company reserves the right to change the benefits it offers or the terms of such benefits from time to time. The Company will provide you with an initial
vacation day accrual rate based on service comparable to that of an existing employee with 10 years of prior service to the Company. 

 7. Immigration Laws. This offer of employment is contingent on your providing proper
documentation of your identity and authorization to work in the United States under applicable immigration laws, as required by Form I-9 of the US Department of Homeland Security. 

8. Employee Confidentiality and Invention Assignment Agreement. As a condition of this offer of employment, you will be required
to promptly complete, sign and return the Company’s standard form of employee confidentiality and invention assignment agreement (the “ECIA”). 
 9. No Conflicts. In this position, you will be expected to devote your full business time, attention and energies to the performance of your duties with the Company. We also ask that, before
signing this letter, you disclose to the Company any and all agreements relating to your prior employment that may affect your eligibility to be employed by the Company or limit the manner in which you may be employed. It is the Company’s
understanding that any such agreements will not prevent you from performing the duties of your position and you represent that such is the case. 
 10. General. This offer letter and the ECIA, when signed by you, set forth the terms of your employment with the Company and supersede any and all prior representations and agreements made to or
with you by the Company, any of its predecessors or affiliates, or any of their respective employees or agents, whether written or oral. As a Company employee, you will also be expected to abide by Company rules and regulations, whether set forth in
a Company-approved employee handbook or otherwise, that may be modified from time to time. In the event of a conflict between the terms and provisions of this offer letter and the ECIA, the terms and provisions of the ECIA will control. Any
amendment of this offer letter or any waiver of a right under this offer letter must be set forth in a writing signed by you and an authorized officer of the Company to be effective. The law of the state in which you are employed will govern this
offer letter. In the event of any dispute or claim relating to or arising out of our employment relationship, you and the Company agree that we are both waiving any and all rights to a jury trial in connection with such dispute or claim. 

Lastly, this offer of employment is contingent on the satisfactory completion of a background check. It is also contingent in part on
your submitting to a pre-employment drug-screening test for the presence of drugs. Human Resources will provide the necessary documents once you have returned your signed offer letter. 

We look forward to you joining the Company. If the foregoing terms are agreeable, please indicate your acceptance by signing this offer
letter in the space provided below and returning it to me, along with your completed and signed ECIA.

 AMENDMENT TO OFFER OF EMPLOYMENT 

This AMENDMENT (“Amendment”) to that certain Offer Letter of Employment with M/A-COM Technology Solutions Inc.
dated as of August 7, 2009 (the “Original Employment Agreement”) is made as of December 21, 2010, by and between M/A-COM Technology Solutions Inc., a Delaware corporation (the “Company”), and
Robert S. Donahue (the “Employee”). Capitalized terms used herein without definition shall have the respective meanings provided therefor in the Original Employment Agreement. 

RECITALS 

WHEREAS, the Company and the Employee entered into the Original Employment Agreement; 

WHEREAS, the parties now desire to amend the Original Employment Agreement to reflect certain changes to the terms and conditions
contained therein; 
 NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, and
other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the Company and the Employee hereby agree as follows: 
 AGREEMENT 
 11. Section 4(a) of the Original Employment Agreement is
hereby amended and restated in its entirety as follows: 
 “Our at-will relationship notwithstanding, if the Company
terminates your employment with the Company for any reason other than for “Cause” (as defined below) or you resign for “Good Reason” (as defined below) (each an “Involuntary Termination”), and in either case you
sign and deliver to the Company within 52 days after such termination of employment and do not revoke within any applicable 7-day revocation period (or other revocation period set forth by the Company ending prior to the 60th day after termination
of employment) a general release of claims in the Company’s favor in a form and substance acceptable to the Company (the “Release”), then you shall be entitled to receive as severance pay continuation of your monthly salary, as
in effect and payable in accordance with the Company’s standard payroll policies on the date of such termination (and in no event less frequently than monthly), including compliance with applicable withholding, for a period of six
(6) months (or alternatively, if such Involuntary Termination occurs within six (6) months following a Change of Control (as defined below), for a period twelve (12) months) following your date of employment with the Company (such
period is hereinafter referred to as the “Severance Period”). To the extent required to comply with or be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (“Code
Section 409A”), any payments that would otherwise have been made during the 60-day period following your termination of employment shall not be made and shall be accumulated and paid in a single lump sum after such Release is
signed and delivered to the Company and after the expiration of any applicable revocation period (as set forth in the preceding sentence) on or prior to the 60th day following your termination of employment; provided that if the period of 60 days
following your termination of employment spans two calendar years, such accumulated payment to the extent required by Code Section 409A shall be paid in the second such calendar year.” 

 12. A new Section 4(c) is hereby inserted into the Original Employment Agreement and
the prior Section 4(c) is renumbered as Section 4(d) and all references amended as necessary. The new Section 4(c) is as follows: 
 “Optional Severance. If your employment terminates for any reason other than an Involuntary Termination the Company may elect, in its sole discretion, to pay you severance pay and benefit
reimbursements in the amounts and on the terms set forth in Sections 4(a) and (b) for any period up to six (6) months if the Termination does not take place within six (6)months following a Change in Control and any period up to twelve
(12) months if the Termination does take place within six months following a Change in Control. If the Company makes such an election, the duration elected by the Company shall be deemed to be the “Severance Period” for all purposes
under this Agreement.” 
 13. Section 5(c) of the Original Employment Agreement is hereby amended by replacing the
phrase “prohibited by Sections 5(b) and (c)” in the second sentence with the phrase “prohibited by Sections 5(a) and (b)”. 
 14. A new Section 11 is hereby added to the Original Employment Agreement as follows: 
 “This offer of employment is intended to be interpreted and operated to the fullest extent possible so that the payments and benefits under this offer of employment either shall be exempt from the
requirements of Code Section 409A under Treasury Regulation section 1.409A-1(b)(9)(iii) or otherwise or shall comply with the requirements of Code Section 409A; provided, however, that notwithstanding anything to the contrary in this offer
of employment in no event shall the Company be liable to you for or with respect to any taxes, penalties or interest which may be imposed upon you pursuant to Code Section 409A. In accordance with the preceding sentence, the date on which a
“separation from service” pursuant to Code Section 409A occurs shall be treated as the termination of employment date for purposes of determining the timing of payments and benefits under this offer of employment to the extent
necessary to have such payments and benefits under this offer of employment be exempt from the requirements of Code Section 409A or comply with the requirements of Code Section 409A.” 

15. Except as expressly amended hereby, the Original Employment Agreement shall remain in full force and effect. This Amendment shall
not, except as expressly provided herein, be deemed to be a consent to any waiver or modification of any other terms or provisions of the Original Employment Agreement. 
 16. This Amendment may be signed in any number of counterparts, each of which shall be deemed an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

 [Remainder of page intentionally left blank.] 

 IN WITNESS WHEREOF, the parties have executed this Amendment as of the date first above
written.
