lapse. By electing to participate each participant agrees to the Holding Period. 
  

	7.	EMPLOYEE STOCK PURCHASE AGREEMENT. 

  
 An Employee Stock Purchase Account will be established for each Participant in the Plan for bookkeeping purposes, and payroll deductions made under
Section 6 will be credited to such Accounts. However, prior to the purchase of shares in accordance with Section 8 or withdrawal from or termination of the Plan in accordance with provisions hereof, the Company may use for any valid
corporate purpose all amounts deducted from a Participant’s wages under the Plan and credited for bookkeeping purposes to his Account. 
  
 The Company shall be under no obligation to pay interest on funds credited to a Participant’s Account, whether upon purchase of shares in accordance
with Section 8 or upon distribution in the event of withdrawal from or termination of the Plan as herein provided. 
  

	8.	PURCHASE OF SHARES. 

  
 Each Eligible Employee who is a Participant in the Plan automatically and without any act on his part will be deemed to have exercised his option on each
Exercise Date to the extent that the balance then in his Account under the Plan is sufficient to purchase at the Purchase Price whole shares of the Common Stock subject to his option, subject to the Share Limitations and the Section 423(b)(8)
limitation described in Section 3. Any balance remaining in the Participant’s Account shall be retained in the Participant’s Account and added to the aggregate payroll deductions during the next Purchase Period for purposes of
determining the number of shares which may be acquired by such Participant pursuant to Section 3, unless a refund is requested by the Participant. No interest shall be paid on the balance remaining in any Participant’s Account. 

 

	9.	WITHDRAWAL. 

  
 A Participant who has elected to authorize payroll deductions for the purchase of shares of Common Stock may cancel his election by written notice of
cancellation (“Cancellation”) delivered to the office or person designated by the Company to receive Stock Purchase Agreements, but any such notice of Cancellation must be so delivered not later than ten (10) days before the relevant
Exercise Date. 
  
 A Participant will receive in cash, as soon as
practicable after delivery of the notice of Cancellation, the amount credited to his Account. Any Participant who so withdraws from the Plan may again become a Participant at the start of the next Purchase Period in accordance with Section 6.

  
 Upon dissolution or liquidation of the Company every option
outstanding hereunder shall terminate, in which event each Participant shall be refunded the amount of cash then in his Account. If the Company shall at any time merge into or consolidate with another corporation, the holder of each option then
outstanding will thereafter be entitled to receive at the next Exercise Date, upon exercise of such option and for each share as to which such option was 

  

 4 

 
exercised, the securities or property which a holder of one share of Common Stock was entitled upon and at such time of such merger or consolidation. In
accordance with this paragraph and this Plan, the Board of Directors or Compensation Committee, if any, shall determine the kind or amount of such securities or property which such holder of an option shall be entitled to receive. A sale of all or
substantially all of the assets of the Company shall be deemed a merger or consolidation for the foregoing purposes. 
  

	10.	TRANSFER RESTRICTION/HOLDING PERIOD. 

  
 The shares of stock purchased may not be sold or transferred until the expiration of the Holding Period. All stock certificates issued pursuant to this
Plan shall be held in escrow by either the Company or the transfer agent and registrar of the Company’s Common Stock, as the Company shall in its sole discretion determine, until the expiration of the Holding Period. Effective July 1,
2005, the restrictions on transfer during the Holding Period shall no longer be applicable. 
  

	11.	ISSUANCE OF STOCK CERTIFICATES. 

  
 The shares of Common Stock purchased by a Participant shall, for all purposes, be deemed to have been issued and sold at the close of business on the
Exercise Date. Prior to that date none of the rights or privileges of a shareholder of the Company, including the right to vote or receive dividends, shall exist with respect to such shares. 
  
 Within a reasonable time after the Exercise Date, the Company shall notify
the transfer agent and registrar of the Common Stock of the Participant’s ownership of the number of shares of Common Stock purchased by a Participant for the Purchase Period, which shall be registered either in the Participant’s name or
jointly in the names of the Participant and his spouse with right of survivorship as the Participant shall designate in his Stock Purchase Agreement. Such designation may be changed at any time by filing notice thereof with the party designated by
the Company to receive such notices. 
  

	12.	TERMINATION OF EMPLOYMENT. 

  

	 	(a)	Upon a Participant’s termination of employment for any reason, other than death, no payroll deduction may be made from any compensation due him and the entire balance credited
to his Account shall be automatically refunded, and his rights under the Plan shall terminate. 

  

	 	(b)	Upon the death of a Participant, no payroll deduction shall be made from any compensation due him at time of death, the entire balance in the deceased Participant’s Account
shall be paid in cash to the Participant’s designated beneficiary, if any, under a group insurance plan of the Company covering such employee, or otherwise to his estate, and his rights under the Plan shall terminate. 

 

	13.	RIGHTS NOT TRANSFERABLE. 

  
 The right to purchase shares of Common Stock under this Plan is exercisable only by the Participant during his lifetime and is not transferable by him. If
a Participant attempts to transfer his right to purchase shares under the Plan, he shall be deemed to have requested withdrawal from the Plan and the provisions of Section 9 hereof shall apply with respect to such Participant. 
  

 5 

	14.	NO GUARANTEE OF CONTINUED EMPLOYMENT. 

  
 Granting of an option under this Plan shall imply no right of continued employment with the Company for any Eligible Employee. 
  

	15.	NOTICE. 

  
 Any notice which an Eligible Employee or Participant files pursuant to this Plan shall be in writing and shall be delivered personally or by mail
addressed to Mercury Computer Systems, Inc., 199 Riverneck Road, Chelmsford, MA 01824, Attn: James R. Bertelli. Any notice to a Participant or an Eligible Employee shall be conspicuously posted in the Company’s principal office or shall be
mailed addressed to the Participant or Eligible Employee at the address designated in the Stock Purchase Agreement or in a subsequent writing. 
  

	16.	APPLICATION OF FUNDS. 

  
 All funds deducted from a Participant’s wages in payment for shares purchased or to be purchased under this Plan may be used for any valid corporate
purpose provided that the Participant’s Account shall be credited with the amounts of all payroll deductions as provided in Section 7. 
  

	17.	GOVERNMENT APPROVALS OR CONSENTS. 

  
 This Plan and any offering and sales to Eligible Employees under it are subject to any governmental approvals or consents that may be or become applicable
in connection therewith. Subject to the provisions of Section 17, the Board of Directors of the Company may make such changes in the Plan and include such terms in any offering under this Plan as may be necessary or desirable, in the opinion of
counsel, to comply with the rules or regulations of any governmental authority, or to be eligible for tax benefits under the Code or the laws of any state. 
  

	18.	AMENDMENT OF THE PLAN. 

  
 The Board of Directors may, without the consent of the Participants, amend the Plan at any time, provided that no such action shall adversely affect
options theretofore granted hereunder, and provided that no such action by the Board of Directors without approval of the Company’s shareholders may (a) increase the total number of shares of Common Stock which may be purchased by all
Participants, (b) change the class of employees eligible to receive options under the Plan, or (c) make any changes to the Plan which require shareholder approval under applicable law or regulations, including Section 423 of the Code
and the regulations promulgated thereunder. 
  
 For purposes of
this Section 17, termination of the Plan by the Board of Directors pursuant to Section 18 shall not be deemed to be an action which adversely affects options theretofore granted hereunder. 
  

	19.	TERM OF THE PLAN. 

  
 The Plan shall become effective on the Effective Date, provided that it is approved within twelve months after adoption by the Board of Directors by the
affirmative vote of holders of a majority of the stock of the Company present or represented and entitled to vote at a duly held shareholders’ meeting. The Plan shall continue in effect through June 30, 2007, provided, however, that the
Board of Directors shall have the right to terminate the Plan at any time, but such termination shall not affect options then outstanding under the Plan. It will terminate in any 

  

 6 

 
case when all or substantially all of the unissued shares of stock reserved for the purposes of the Plan have been purchased. If at any time shares of stock
reserved for the purposes of the Plan remain available for purchase but not in sufficient number to satisfy all then unfilled purchase requirements, the available shares shall be apportioned among Participants in proportion to the amount of payroll
deductions accumulated on behalf of each Participant that would otherwise be used to purchase stock and the Plan shall terminate. Upon such termination or any other termination of the Plan, all payroll deductions not used to purchase stock will be
refunded, without interest. 
  

	20.	NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION. 

  
 By electing to participate in the Plan, each Participant agrees to notify the Company in writing immediately after the Participant transfers Common Stock
acquired under the Plan, if such transfer occurs within two years after the first business day of the Purchase Period in which such Common Stock was acquired. Each Participant further agrees to provide any information about such a transfer as may be
requested by the Company or any subsidiary corporation in order to assist it in complying with the tax laws. Such dispositions generally are treated as “disqualifying dispositions” under Sections 421 and 424 of the Code, which have certain
tax consequences to Participants and to the Company and its participating Subsidiaries. The Participant acknowledges that the Company may send a Form W-2, or substitute therefor, as appropriate, to the Participant with respect to any income
recognized by the Participant upon a disqualifying disposition of Common Stock. 
  

	21.	WITHHOLDING OF ADDITIONAL INCOME TAXES. 

  
 By electing to participate in the Plan, each Participant acknowledges that the Company and its participating Subsidiaries are required to withhold taxes
with respect to the amounts deducted from the Participant’s compensation and accumulated for the benefit of the Participant under the Plan and each Participant agrees that the Company and its participating Subsidiaries may deduct additional
amounts from the Participant’s compensation, when amounts are added to the Participant’s account, used to purchase Common Stock or refunded, in order to satisfy such withholding obligations. Each Participant further acknowledges that when
Common Stock is purchased under the Plan, the Company and its participating Subsidiaries may be required to withhold taxes with respect to all or a portion of the difference between the fair market value of the Common Stock purchased and its
purchase price, and each Participant agrees that such taxes may be withheld from compensation otherwise payable to such Participant. It is intended that tax withholding will be accomplished in such a manner that the full amount of payroll deductions
elected by the Participant under Section 6 will be used to purchase Common Stock. However, if amounts sufficient to satisfy applicable tax withholding obligations have not been withheld from compensation otherwise payable to any Participant,
then, notwithstanding any other provision of the Plan, the Company may withhold such taxes from the Participant’s accumulated payroll deductions and apply the net amount to the purchase of Common Stock, unless the Participant pays to the
Company, prior to the exercise date, an amount sufficient to satisfy such withholding obligations. Each Participant further acknowledges that the Company and its participating Subsidiaries may be required to withhold taxes in connection with the
disposition of stock acquired under the Plan and agrees that the Company or any participating subsidiary may take whatever action it considers appropriate to satisfy such withholding requirements, including deducting from compensation otherwise
payable to such Participant an amount sufficient to satisfy such withholding requirements or conditioning any disposition of Common Stock by the 

  

 7 

 
Participant upon the payment to the Company or such subsidiary of an amount sufficient to satisfy such withholding requirements. 
  

	22.	GENERAL. 

  
 Whenever the context of this Plan permits, the masculine gender shall include the feminine and neuter genders.
