 NETSCOUT SYSTEMS, INC. 
  
 FORM OF RESTRICTED STOCK UNIT
AGREEMENT – TERMS AND CONDITIONS 
  
 NetScout Systems, Inc. (the “Company”) agrees to award to the recipient specified on the cover page hereof (the
“Recipient”), and the Recipient agrees to accept from the Company, the number of restricted stock units (the “RSUs”) specified on the cover page hereof representing an equivalent number of shares of the
Company’s Common Stock (the “Underlying Shares”), on the following terms: 
  
 1. Grant Under Plan. This Restricted Stock Agreement (the “Agreement”) is made pursuant to and is governed by the Company’s
1999 Stock Option and Incentive Plan, as amended and in effect from time to time (the “Plan”), and, unless the context otherwise requires, capitalized terms used herein shall have the same meanings as in the Plan. 
  
 2. Vesting if Business Relationship Continues. 
  
 (a) Vesting Schedule. If the Recipient has maintained
continuously Business Relationship with the Company through each date specified on the cover page hereof, a portion of the RSUs shall vest on such date in such amounts as are set forth opposite the such date on the cover page hereof. If the
Recipient’s Business Relationship with the Company is terminated by the Company or by the Recipient for any reason, whether voluntarily or involuntarily, no additional RSUs shall become vested RSUs under any circumstances with respect to the
Recipient. Any determination under this Agreement as to Business Relationship status or other matters referred to above shall be made in good faith by the Board, whose decision shall be final and binding on all parties. 
  
 “Business Relationship” means service to
the Company or its successor in the capacity of an employee, officer, director, consultant, or advisor. 
  
 (b) Termination of Business Relationship. For purposes hereof, a Business Relationship shall not be considered as having terminated
during any military leave, sick leave, or other leave of absence if approved in writing by the Company and if such written approval, or applicable law, contractually obligates the Company to continue the Business Relationship of the Recipient after
the approved period of absence (an “Approved Leave of Absence”). In the event of an Approved Leave of Absence, vesting of RSUs shall be suspended (and all subsequent vesting dates shall be postponed by the length of the period of
the Approved Leave of Absence) unless otherwise provided in the Company’s written approval of the leave of absence that specifically refers to this Agreement. For purposes hereof, a Business Relationship shall include a consulting arrangement
between the Recipient and the Company that immediately follows termination of employment, but only if so stated in a written consulting agreement executed by the Company that specifically refers to this Agreement. 
  
 (c) Acceleration Upon Acquisition. If the Recipient
has maintained continuously a Business Relationship with the Company through the date an Acquisition of the Company is consummated, twenty-five percent (25%) of the RSUs awarded pursuant to this Agreement that have not vested as of immediately prior
to such date shall vest as of the date such Acquisition is consummated and the amount of Underlying Shares corresponding to such vested RSUs shall be issued to the Recipient in accordance with Section 3. 
  
 3. Issuance of Underlying Shares. With respect to any RSUs that become
vested RSUs pursuant to Section 2, subject to Section 5, the Company shall issue to the Recipient, as soon as practicable following the applicable vesting date specified on the cover page hereof, the number of Underlying Shares equal to
the number of RSUs vesting on such vesting date, provided that, if the vesting date of any portion of the RSUs shall occur during either a regularly scheduled or special “blackout period” of the Company wherein Recipient is precluded from
selling shares of the Company’s Common Stock, the receipt of the corresponding Underlying Shares issuable with respect to such vesting date pursuant to this Agreement shall be deferred until after the expiration of such blackout period. The
Underlying Shares the receipt of which was deferred as provided above shall be issued to Recipient as soon as practicable after the expiration of the blackout period. 
  
 4. Restrictions on Transfer. The Recipient shall not sell, assign, transfer, pledge, encumber or dispose of all or
any of his or her RSUs. 









 5. Withholding Taxes. All grants made pursuant to this Agreement shall be subject to withholding
of all applicable income and employment taxes resulting from the issuance or vesting of the RSUs or the delivery of the Underlying Shares (the “Tax Obligations”). The Company may, and the Recipient hereby agrees that and authorizes
the Company on its behalf to, withhold, sell, and/or arrange for the sale of such number of Underlying Shares otherwise issuable to the Recipient pursuant to this Agreement as deemed necessary by the Company, in its sole discretion, to ensure that
the Tax Obligations can be satisfied, including the right to sell shares having a fair market value greater than the Tax Obligations; provided, however, that for this purpose the Tax Obligations shall be computed based on the minimum
statutory withholding rates for federal, state, local, and foreign income and employment tax purposes; provided, further, however, that if the Company decides to satisfy the Tax Obligations by withholding shares otherwise
issuable hereunder (rather than by selling or arranging for the sale of shares on behalf of the Recipient), the Company shall not withhold shares having a fair market value greater than the Tax Obligations. The Recipient further agrees that, if the
Company elects not to withhold, sell, or arrange for the sale of the amount of Underlying Shares sufficient to satisfy the full amount of the Tax Obligations, the Company may withhold such shortfall in cash from wages or other remuneration or the
Recipient will deliver to the Company, in cash, the amount of such shortfall. The Recipient further agrees that the Recipient shall not sell any of the Underlying Shares during the period of time that the Company is acting on the Recipient’s
behalf to withhold, sell, and/or arrange for the sale of the number of Underlying Shares necessary to satisfy the Recipient’s Tax Obligations. Notwithstanding the preceding three sentences, the Recipient may, by written notice to the Company at
least ten business days before the applicable vesting date specified on the cover page hereof, elect to pay in cash the applicable Tax Obligations, or make other appropriate provisions acceptable to the Company for the payment of the applicable Tax
Obligations, including the withholding from any payroll or other amounts due to the Recipient. 
  
 Recipient further agrees to take any further actions and execute any additional documents as may be necessary to effectuate the provisions of this Section 5 and the Recipient hereby grants the Company a
irrevocable power of attorney to sign such additional documents on the Recipient’s behalf if the Company is unable after reasonable efforts to obtain Recipient’s signature on such additional documents. This power of attorney is coupled
with an interest and is irrevocable by the Recipient. 
  
 6.
Arbitration. Any dispute, controversy, or claim arising out of, in connection with, or relating to the performance of this Agreement or its termination shall be settled by arbitration in The Commonwealth of Massachusetts, pursuant to the
rules then obtaining of the American Arbitration Association. Any award shall be final, binding and conclusive upon the parties and a judgment rendered thereon may be entered in any court having jurisdiction thereof. 
  
 7. Provision of Documentation to Recipient. By signing the cover page
of this Agreement, the Recipient acknowledges receipt of a copy of this entire Agreement, a copy of the Plan, and a copy of the Plan’s related prospectus. 
  

8. Section 409A of the Internal Revenue Code. The RSUs granted hereunder are intended to avoid the potential adverse tax consequences to
the Recipient of Section 409A of the Internal Revenue Code of 1986, as amended, and the Board may make such modifications to this Agreement as it deems necessary or advisable to avoid such adverse tax consequences. 
  
 9. Rights as Stockholder. The Recipient shall have no rights as a
stockholder of the Company with respect to any RSUs covered by this Agreement until the issuance of the Underlying Shares. 
  
 10. Miscellaneous. 
  
 (a) Notices. All notices hereunder shall be in writing and shall be deemed given when sent by certified or registered mail, postage
prepaid, return receipt requested, if to the Recipient, to the address set forth on the cover page hereof or at the address shown on the records of the Company, and if to the Company, to the Company’s principal executive offices, attention of
the Corporate Secretary.

 (b) Entire Agreement; Modification. This Agreement constitutes the entire
agreement between the parties relative to the subject matter hereof, and supersedes all proposals, written or oral, and all other communications between the parties relating to the subject matter of this Agreement. This Agreement may be modified,
amended or rescinded only by a written agreement executed by both parties signatories to this Agreement. In the event of a conflict between the terms of this Agreement and the Plan, the terms of the Plan shall control. 
  
 (c) Fractional RSUs or Underlying Shares. All
fractional RSUs or Underlying Shares resulting from the adjustment provisions contained in the Plan shall be rounded down to the nearest whole unit or share. 
  

(d) Severability. The invalidity, illegality or unenforceability of any provision of this Agreement shall in no way affect the
validity, legality or enforceability of any other provision. 
  
 (e) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, subject to the limitations set forth herein.

  
 (f) Governing Law. This Agreement
shall be governed by and interpreted in accordance with the laws of Delaware without giving effect to the principles of the conflicts of laws thereof. 
  
 (g) No Obligation to Continue Business Relationship. Neither the Plan, nor this Agreement, nor any provision hereof imposes any
obligation on the Company to continue a Business Relationship with the Recipient. 
  
 (h) For purposes of Sections 2, 5 and 10(g), the “Company” shall mean the Company as defined in Section 8(a) of the Plan.
