 Exhibit 10.1 
 NETSCOUT SYSTEMS, INC. 
 2007 EQUITY INCENTIVE PLAN

 1    Purpose and Eligibility 
 The purpose of this 2007 Equity Incentive Plan (the “Plan”) of NetScout Systems, Inc. (the “Company”) is to provide restricted stock units, stock, stock options, and other equity interests in the Company (each an
“Award”) to employees, officers, directors, consultants and advisors of the Company and its Subsidiaries, all of whom are eligible to receive Awards under the Plan. Any person to whom an Award has been granted under the Plan is called a
“Participant”. Additional definitions are contained in Section 9. 
 2     Administration 
 2.1 Administration by Board of Directors. The Plan will be administered by the Board of Directors of the Company (the “Board”). The
Board, in its sole discretion, shall have the authority to grant and amend Awards, to adopt, amend and repeal rules relating to the Plan and to interpret and correct the provisions of the Plan and any Award. All decisions by the Board shall be final
and binding on all interested persons. Neither the Company nor any member of the Board shall be liable for any action or determination relating to the Plan. 
 2.2 Appointment of Committees. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board
(a “Committee”). All references in the Plan to the “Board” shall mean such Committee or the Board. 
 2.3
Delegation to Executive Officers. To the extent permitted by applicable law, the Board may delegate to one or more executive officers of the Company the power to grant Awards and exercise such other powers under the Plan as the Board may
determine, provided that the Board shall fix the maximum number of Awards to be granted and the maximum number of shares issuable to any one Participant pursuant to Awards granted by such executive officers. 
 3     Stock Available for Awards 
 3.1
Type of Security; Number of Shares. Subject to adjustment under Section 3.3, the aggregate number of shares of common stock of the Company (the “Common Stock”) that may be issued pursuant to the Plan is 5,000,000 shares. If any
Award expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued Common Stock covered by such Award shall again be available for the grant of Awards under the Plan. If shares of Common Stock issued pursuant to the Plan
are repurchased by, or are surrendered or forfeited to, the Company at no more than cost, such shares of Common Stock shall again be available for the grant of Awards under the Plan; provided, however, that the cumulative number of such
shares that may be so reissued under the Plan will not exceed 5,000,000 shares. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares. 
 3.2 Per-Participant Limit. Subject to adjustment under Section 3.3, no Participant may be granted Awards during any one fiscal year with
respect to more than 500,000 shares of Common Stock. 
 3.3 Adjustment to Common Stock. In the event of any stock split, stock
dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off, split-up, or other similar change in capitalization or event (an “Extraordinary Capitalization Event”), (i) the
number and class of securities available for Awards under the Plan and the per-Participant share limit, (ii) the number and class of securities, vesting schedule and exercise price per share subject to each outstanding Option, (iii) the
repurchase price per security subject to repurchase, and (iv) the terms of each other outstanding stock-based Award shall be adjusted (or substituted Awards may be made) by the Board in a proportionate and equitable manner to the extent that
such Extraordinary Capitalization Event increases or decreases the actual outstanding shares of Common Stock of the Company as of immediately prior to such Extraordinary Capitalization Event. 







 4     Stock Options 
 4.1 General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option
and the conditions and limitations applicable to the exercise of each Option and the Common Stock issued upon the exercise of each Option, including vesting provisions, repurchase provisions and restrictions relating to applicable federal or state
securities laws, as it considers advisable. 
 4.2 Incentive Stock Options. An Option that the Board intends to be an “incentive
stock option” as defined in Section 422 of the Code (an “Incentive Stock Option”) shall be granted only to employees of the Company or a Subsidiary and shall be subject to and shall be construed consistently with the requirements
of Section 422 of the Code. The Board and the Company shall have no liability if an Option or any part thereof that is intended to be an Incentive Stock Option does not qualify as such. An Option or any part thereof that does not qualify as an
Incentive Stock Option is referred to herein as a “Nonqualified Stock Option”. 
 4.3 Exercise Price. The Board shall
establish the exercise price (or determine the method by which the exercise price shall be determined) at the time each Option is granted and specify it in the applicable option agreement; provided that the exercise price shall not be less than the
fair market value of the Company’s Common Stock on the date of grant. The exercise price with respect to an Incentive Stock Option granted to an employee who at the time of grant owns (directly or under the attribution rules of
Section 424(d) of the Code) stock representing more than 10% of the voting power of all classes of stock of the Company or of any Subsidiary shall be at least 110% of the fair market value of the Company’s Common Stock on the date of
grant. 
 4.4 Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the
Board may specify in the applicable option agreement; provided that no Incentive Stock Option shall expire later than 10 years from its date of grant, and no Incentive Stock Option granted to an employee who owns (directly or under the attribution
rules of Section 424(d) of the Code) stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any Subsidiary shall expire later than 5 years from its date of grant. 
 4.5 Exercise of Option. Options may be exercised only by delivery to the Company of a written notice of exercise signed by the proper person
together with payment in full as specified in Section 4.6 for the number of shares for which the Option is exercised. 
 4.6 Payment
Upon Exercise. Common Stock purchased upon the exercise of an Option shall be paid for by one or any combination of the following forms of payment: 
 4.6.1 by check payable to the order of the Company; 
 4.6.2 except as otherwise explicitly
provided in the applicable option agreement, and only if the Common Stock is then publicly traded, delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the
exercise price, or delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price; or 
 4.6.3 to the extent explicitly provided in the applicable option agreement and not otherwise prohibited by applicable law, by
(x) delivery of shares of Common Stock owned by the Participant valued at fair market value (as determined by the Board or as determined pursuant to the applicable option agreement), (y) delivery of a promissory note of the Participant to
the Company (and delivery to the Company by the Participant of a check in an amount equal to the par value of the shares purchased), or (z) payment of such other lawful consideration as the Board may determine. 







 4.7 No Repricing. Other than in connection with a change in the Company’s capitalization (as
described in Section 3.3), without stockholder approval (i) the exercise price of an Option may not be reduced, and (ii) no Option may be amended or cancelled for the purpose of repricing, replacing or regranting such Option with an
exercise price that is less than the original exercise price of such Option. 
 5     Restricted Stock 
 5.1 Grants. The Board may grant Awards entitling recipients to acquire shares of Common Stock, subject to (i) delivery to the Company by the
Participant of a check in an amount at least equal to the par value of the shares purchased, and (ii) the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant
in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award (each, a “Restricted Stock Award”).

 5.2 Terms and Conditions. The Board shall determine the terms and conditions (or provide for no conditions) of any such Restricted
Stock Award. Any stock certificates issued in respect of a Restricted Stock Award shall be registered in the name of the Participant and, unless otherwise determined by the Board, deposited by the Participant, together with a stock power endorsed in
blank, with the Company (or its designee). After the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or, if the Participant has
died, to the beneficiary designated by a Participant, in a manner determined by the Board, to receive amounts due or exercise rights of the Participant in the event of the Participant’s death (the “Designated Beneficiary”). In the
absence of an effective designation by a Participant, Designated Beneficiary shall mean the Participant’s estate. 
 6
    Restricted Stock Units 
 The Board may grant Awards entitling recipients to receive shares of Common Stock (each, a
“Restricted Stock Unit Award”), subject to any terms and conditions established for such Awards. The Board shall determine the terms and conditions (or provide for no conditions) of any such Restricted Stock Unit Award and such terms and
conditions will be reflected in the applicable Restricted Stock Unit Award agreement. 
 7     Other Stock-Based Awards 
 The Board shall have the right to grant other Awards based upon the Common Stock having such terms and conditions as the Board may determine, including,
without limitation, the grant of shares based upon certain conditions, the grant of securities convertible into Common Stock and the grant of stock appreciation rights, phantom stock awards, or other stock units. 
 8     General Provisions Applicable to Awards 
 8.1 Transferability of Awards. 
 8.1.1 Except as the Board may otherwise determine or provide in an Award, Awards
shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, except as set forth in
Section 8.1.2 below, during the life of the Participant, shall be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees. 
 8.1.2 During the life of the Participant, an Option shall be exercisable only by him, by a conservator or guardian duly appointed for him
by reason of his incapacity or by the person appointed by the Participant in a durable power of attorney acceptable to the Company’s counsel. Notwithstanding anything to the contrary in this Section 8.1, the Board may in its discretion
permit a Participant who has received a Nonqualified 








 
Stock Option to transfer the Nonqualified Stock Option to a member of the Immediate Family (as hereinafter defined) of the Participant, to a trust solely for
the benefit of the Participant and the Participant’s Immediate Family or to a partnership or limited liability company whose only partners or members are the Participant and members of the Participant’s Immediate Family. “Immediate
Family” shall mean, with respect to any Participant, the Participant’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or
sister-in-law, and shall include adoptive relationships. 
 8.2 Documentation. Each Award under the Plan (other than a grant of stock
with no restrictions) shall be evidenced by a written instrument in such form as the Board shall determine or as executed by an officer of the Company pursuant to authority delegated by the Board. Each Award may contain terms and conditions in
addition to those set forth in the Plan provided that such terms and conditions do not contravene the provisions of the Plan. 
 8.3
Board Discretion. The terms of each type of Award need not be identical, and the Board need not treat Participants uniformly. 
 8.4
Termination of Status. The Board shall determine the effect on an Award of the disability, death, retirement, authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the
period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award. 
 8.5    Acquisition of the Company. 
 8.5.1 Consequences of an Acquisition. 
 8.5.1.A Unless otherwise expressly provided in the applicable Option or Award, upon the occurrence of an Acquisition, the Board or the
board of directors of the surviving or acquiring entity (as used in this Section 8.5.1.A, also the “Board”) shall, as to outstanding Awards (on the same basis or on different bases, as the Board shall specify), make appropriate
provision for the continuation of such Awards by the Company or the assumption of such Awards by the surviving or acquiring entity and by substituting on an equitable basis for the shares then subject to such Awards either (a) the consideration
payable with respect to the outstanding shares of Common Stock in connection with the Acquisition, (b) shares of stock of the surviving or acquiring corporation or (c) such other securities as the Board deems appropriate, the fair market
value of which (as determined by the Board in its sole discretion) shall not materially differ from the fair market value of the shares of Common Stock subject to such Awards immediately preceding the Acquisition. In addition to or in lieu of the
foregoing, with respect to outstanding Options, the Board may, upon written notice to the affected optionees, provide that one or more Options must be exercised, to the extent then exercisable or to become exercisable as a result of the Acquisition,
within a specified number of days of the date of such notice, at the end of which period such Options shall terminate; or terminate one or more Options in exchange for a cash payment equal to the excess of the fair market value (as determined by the
Board in its sole discretion) of the shares subject to such Options (to the extent then exercisable or to become exercisable as a result of the Acquisition) over the exercise price thereof. 
 8.5.1.B An “Acquisition” shall mean: (x) any merger or consolidation after which the voting securities of the Company
outstanding immediately prior thereto represent (either by remaining outstanding or by being converted into voting securities of the surviving or acquiring entity) less than 50% of the combined voting power of the voting securities of the Company or
such surviving or acquiring entity outstanding immediately after such event; or (y) any sale of all or substantially all of the assets or capital stock of the Company (other than in a spin-off or similar transaction) or (z) any other
acquisition of the business of the Company, as determined by the Board. 







 8.5.2 Assumption of Options Upon Certain Events. In connection with a merger or
consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Awards under the Plan in substitution for stock and stock-based awards issued by such entity or an affiliate
thereof. The substitute Awards shall be granted on such terms and conditions as the Board considers appropriate in the circumstances. 
 8.6
Withholding. Each Participant shall pay to the Company or an employing Subsidiary, or make provisions satisfactory to the Company or an employing Subsidiary for payment of, any taxes required by law to be withheld in connection with Awards to
such Participant no later than the date of the event creating the tax liability. The Board may allow Participants to satisfy such tax obligations in whole or in part by transferring shares of Common Stock, including shares retained from the Award
creating the tax obligation, valued at their fair market value (as determined by the Board or as determined pursuant to the applicable option agreement) to the extent permitted by law; provided, however, that payment of withholding obligation in the
form of shares shall not be made with respect to an amount in excess of the minimum required withholding. The Company or an employing Subsidiary may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind
otherwise due to a Participant. 
 8.7 Amendment of Awards. The Board may amend, modify or terminate any outstanding Award including,
but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonqualified Stock Option; provided that the Participant’s
consent to such action shall be required unless the Board determines that the action, taking into account any related action, would not materially and adversely affect the Participant. 
 8.8 Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in
connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered
to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations. 
 8.9 Acceleration. The Board may at any time provide that any Options shall become immediately exercisable in full or in part, that any Restricted Stock Awards shall be free of some or all restrictions, or that
any other stock-based Awards may become exercisable in full or in part or free of some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be, despite the fact that the foregoing actions may (i) cause
the application of Sections 280G and 4999 of the Code if a change in control of the Company occurs, or (ii) disqualify all or part of the Option as an Incentive Stock Option. 
 8.10 Awards to Non-United States Persons. Awards may be made to Participants who are foreign nationals or employed outside the United States on
such terms and conditions different from those specified in the Plan as the Board considers necessary or advisable to achieve the purposes of the Plan or to comply with applicable laws. The Board shall have the right to amend the Plan, consistent
with its authority to amend the Plan as set forth in Section 9.5, to obtain favorable tax treatment for such Participants, and any such amendments shall be evidenced by an Appendix to the Plan. The Board may delegate this authority to a
Committee thereof.

 9.2 No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award, and the grant of an Award shall not be

liability or claim under the Plan. 
 9.3 No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant

persons subject to Section 16 of the Exchange Act (“Insiders”), transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successor under the Exchange Act. To the extent any provision of
the Plan or action by the Board, or any Committee thereof, fails to so comply, it shall be deemed to be modified so as to be in compliance with such Rule or, if such modification is not possible, it shall be deemed to be null and void, to the extent
permitted by law and deemed advisable by the Board.
