 2.3 The obligations of the Agents are several and not joint. 
  

	3.	THE NOTES 

 3.1 The Notes shall be

	4.	PAYING AGENCY 

 4.1 The Issuer
shall remit the funds necessary for the payment of interest on and principal of the Notes to the Fiscal Agent, in NOK in same-day funds, to such account at the Fiscal Agent in London as the Fiscal Agent may from time to time specify (the
“Redemption Account”) by 11:00 am (London time) on the date on which such payment is due (or by such earlier time as may be determined by the Fiscal Agent in its absolute discretion). If the Fiscal Agent determines that payment in
accordance with this provision is required to be made earlier than as stated herein, the Fiscal Agent shall provide the Issuer with not less than 21 Business Day’s notice in writing of such requirement. Business Day shall mean a day on which
commercial banks and foreign exchange markets settle payments and are open for general business in each of London, Oslo and New York City. 

The Issuer hereby authorizes and directs the Fiscal Agent, from the amounts so paid to it, to make payment of the principal of, and interest on, the
Notes on the due date for payment set forth in the Conditions and this Agreement. The Fiscal Agent shall be entitled to make payments net of any taxes or other sums required to be withheld or deducted by any applicable law. 

The Issuer shall confirm to the Fiscal Agent not later than 10:00 a.m. (London time) on the second Business Day before the relevant date for such payment
that it has issued irrevocable payment instructions for such payment to be made. 
 4.2 If for any reason the Fiscal Agent does not receive
unconditionally the full amount payable by the Issuer on the relevant due date in respect of all the outstanding or maturing Notes, the Fiscal Agent shall as soon as reasonably practicable notify the Issuer by facsimile. The Fiscal Agent shall not
be bound to make any payment of principal or interest in respect of the Notes until the Fiscal Agent has received to its order the full amount of the monies then due and payable in respect of all outstanding or maturing Notes, provided, however,
that if the Fiscal Agent shall, in its discretion, make any payment of principal or interest on or after the due date therefor in respect of the Notes prior to its unconditional receipt of the full amount then due and payable in respect of all
outstanding Notes, the Issuer will promptly pay such amount to the Fiscal Agent and will compensate the Fiscal Agent at a rate equal to the Fiscal Agent’s cost of funding. 

  
 3 

 4.3 Out of the sums paid to the Fiscal Agent in respect of interest and principal on the Notes, the Fiscal
Agent will make payment free of charge to the registered holder of the International Global Note and the DTC Global Note as stipulated in Clause 9 below, in the amounts specified in the Conditions. The Fiscal Agent shall obtain from the Registrar,
and the Registrar shall supply, such details as are required for the Fiscal Agent to make payment as stated above. 
 4.4 In respect of the
monies paid to it relating to any Note, the Fiscal Agent 
 4.4.1 shall not be entitled to exercise any lien, right of set-off or
similar claim (including without limitation any claim arising from or relating to any other issue of securities by the Issuer), 

4.4.2 shall not be required to account for interest thereon and 
 4.4.3 money held by it need not be segregated except as may be required by applicable law. 
 Any
funds held by the Fiscal Agent are held as banker and shall not be subject to the UK FCA Client Money Rules 
  

	5.	DOCUMENTS FOR INSPECTION AND PUBLICATION OF NOTICES 

 5.1 On behalf and at the request and expense of the Issuer, the Fiscal Agent shall cause to be published any notices required to be given by the Issuer in accordance with the Conditions. 

5.2 The Issuer shall provide to the Fiscal Agent sufficient copies of all documents required by the Conditions to be available for issue or inspection,
and the Fiscal Agent shall make such copies available to Noteholders upon their request. 
 5.3 To the extent practicable, the Issuer shall
provide the Fiscal Agent with a copy (prior to publication) of all notices to be issued in connection with the Notes. 
  

	6.	CANCELLATION OF THE GLOBAL NOTES 

6.1 Subject to the terms of the Indenture, as soon as practicable upon the Issuer’s request, the Registrar shall take all measures necessary to
cancel any Notes which the Issuer has repurchased or whose maturity has been accelerated pursuant to the Conditions. The Registrar shall cause any such Notes (i) to the extent represented by the International Global Note, to be cancelled
resulting in a reduction in the aggregate amount of the Notes represented by the International Global Note by the aggregate amount of Notes so cancelled, and (ii) to the extent represented by the DTC Global Note, to be cancelled in accordance
with the procedures established for that purpose by DTC, resulting in a reduction in the aggregate amount of the Notes represented by the DTC Global Note by the aggregate amount of the Notes so cancelled. 

6.2 On the same day such cancellation is effected, the Registrar shall record such cancellation of Notes on the Register in such a way that the aggregate
principal amount of Notes cancelled at any time together with the aggregate principal amount of Notes outstanding and represented by the Global Notes shall equal the aggregate principal amount of Notes originally issued by the Issuer. 

6.3 The Registrar shall upon request furnish the Issuer with a notice of cancellation signed by an authorized officer of the Registrar confirming the
cancellation of such Notes and the corresponding reduction of the relevant Global Note(s). 
  

	7.	DUTIES OF THE REGISTRAR 

 7.1 The
Registrar shall maintain the Register in London in accordance with the Conditions. The Register shall show the aggregate amount of Notes represented by each Global Note at the date of issue and all subsequent transfers and exchanges involving a
change in such amounts and the names and 

  
 4 

 
addresses of the registered holders (each a “Payee”). On the first Business Day after the Record Date for any interest payment on the Notes, the Registrar shall send payment
details in respect of the Payees and the NOK accounts to which transfers should be made to the Fiscal Agent. 
 7.2 Transfers or exchanges of
Notes will be made in accordance with the Conditions, the procedures established for this purpose between Euroclear, Clearstream, DTC and the Registrar, and Euroclear, Clearstream and DTC’s regulations applicable to such transfers or exchanges.
Any such transfer or exchange which results in a change in the aggregate principal amount of Notes held by Euroclear, Clearstream and DTC shall be notified by Euroclear, Clearstream and DTC to the Registrar. The Registrar shall promptly enter
details of the transfer or exchange in the Register, which entry shall, without further action, cause the aggregate principal amount represented by each Global Note to be amended accordingly. 
 7.3 The Registrar shall at all reasonable times during office hours make the Register available to the Issuer and the Fiscal Agent or any person authorised by either of them for inspection and for the
taking of copies thereof or extracts therefrom, and the Registrar shall deliver to such persons such information contained in the Register or relating to the Notes as they may reasonably request. 

 

	8.	DUTIES OF THE TRANSFER AGENT 

 If
and to the extent so specified by the Conditions and in accordance therewith, or if otherwise requested by the Issuer, the Transfer Agent shall make available all relevant forms of transfer, inform the Registrar of the name and address of the
relevant person to be inserted in the Register and carry out such other acts as may be necessary to give effect to the Conditions and this Agreement. 
  

	9.	PAYMENTS TO DTC NOTEHOLDERS 

 9.1
All amounts of principal and interest due in respect of the Notes which are represented by the DTC Global Note (each a “DTC Amount”) shall be paid in U.S. dollars (each such payment being referred to herein as a “U.S. Dollar
Payment”), unless DTC has advised the Fiscal Agent that the relevant Noteholder has made an effective election to receive all or a portion of its payment in Norwegian krona outside DTC (each a “NOK Payment”). 

9.2 The Fiscal Agent shall, from each DTC Amount received by it, make U.S. Dollar Payments in accordance with the Conditions and NOK Payments in
accordance with the Conditions. 
  

	10.	DUTIES OF EXCHANGE AGENT 

 For the purposes of this Clause 10, a “payment date” shall be each date on which the Issuer is obligated to remit funds to the Fiscal Agent pursuant to Clause 4.1. 

The Exchange Agent shall: 
  

	(i)	accept NOK by remittance to an account maintained by the Exchange Agent of the total amount of interest or principal due on any payment date on Notes held by
Cede & Co. (as nominee of DTC) on the Record Date. The Exchange Agent shall be advised by DTC if any beneficial holders of the Notes held by Cede & Co. (as nominee of DTC) have elected to receive payment in NOK and, if so, the
amount of Notes held by such holders and the accounts to which such payments in NOK are to be wired. On the payment date, the Exchange Agent shall wire payment in the appropriate NOK amounts to the accounts indicated. The remainder on such payment
date shall be exchanged by the Exchange Agent pursuant to sub-clause (ii) below into U.S. dollars and, after deduction of any costs relating to such exchange, shall be paid to Cede & Co. (as nominee of DTC) on the payment date; and

  

	(ii)	 on the London business day preceding the applicable payment date, enter into a contract for the purchase of U.S. dollars with the Specified Amount of
NOK for settlement on such payment date. “Specified Amount” shall mean the aggregate amount of NOK payable to all Noteholders holding Notes through participants of DTC that have not elected to receive payments in NOK. The amount of
U.S. dollars payable in respect of a particular payment 

  
 5 

	 	
under the DTC Global Note will be equal to the amount of NOK otherwise payable exchanged into U.S. dollars at the NOK/U.S.$ exchange rate obtained on the London business day prior to the relevant
payment date, less any costs incurred by the Exchange Agent for such conversion (such costs to be shared pro rata among holders under the DTC Global Note accepting U.S. dollar payments in proportion of their respective holdings). If an exchange rate
bid quotation is not so available, the Exchange Agent shall obtain a bid quotation from a leading foreign exchange bank in London selected by the Exchange Agent after consultation with the Issuer. If no bid quotation is so available, payment will be
made in NOK to the account or accounts specified by DTC to the Exchange Agent. In this sub-clause (ii), the term “London business day” shall mean any day on which commercial banks and foreign exchange markets settle payments in London.

  

	11.	CONDITIONS OF APPOINTMENT 

 11.1
The Issuer will pay to the Agents a remuneration for all services rendered hereunder by the Agents in connection with the Notes together with any expenses incurred as separately agreed in a fee letter dated as at the date hereof and executed by the
Agents and the Issuer. 
 11.2 The Issuer will indemnify and hold harmless each of the Agents against any loss, liability or expense which it
may incur or any claim, action or demand which may be made against it arising out of or in connection with such Agent’s appointment or the exercise of its powers and duties hereunder without gross negligence or wilful misconduct on the part of
such Agent. 
 11.3 Each Agent will indemnify and hold harmless the Issuer against any loss, liability or expense incurred by the Issuer or any
claim, action or demand which may be made against the Issuer resulting from the gross negligence or wilful misconduct on the part of such Agent (or such Agent’s officers, employees or agents) and arising out of or in connection with such
Agent’s duties hereunder. Notwithstanding the foregoing, under no circumstances will any Agent be liable to the Issuer or any other person for any consequential loss (being loss of business, goodwill, opportunity or profit) even if advised to
the possibility of such loss or damages. 
 11.4 The indemnities above shall survive the termination or expiry of this Agreement. 

11.5 Each of the Agents shall be protected and shall incur no liability for or in respect of any action taken, omitted or suffered in reliance upon any
instruction or communication from the Issuer or any document reasonably believed by it to be genuine and to have been delivered, signed or sent by the proper party or parties in accordance with the provisions hereof, except such as may result from
its own gross negligence or wilful misconduct or that of its officers, employees or agents. Each of the Agents shall be entitled to do refrain from acting under any instruction, without liability, if the instructions received are conflicting,
unclear or equivocal. 
 11.6 In acting hereunder and in connection with the Notes, the Agents do not assume any relationship of agency and
trust for the Noteholders, and shall not have any obligation towards them except that all funds held by the Fiscal Agent for payment of principal of or interest on the Notes shall be held for payment to the Noteholders and shall be applied as set
forth herein and in the Conditions. Except as otherwise required by applicable law, no Agent will be required to segregate any funds held by it hereunder from any of its other funds. 
 11.7 Nothing herein shall be deemed to require any Agent to advance its own funds in the performance of its duties hereunder. 
 11.8 The Agents may consult with legal and other professional advisers selected in good faith and satisfactory to them and the opinion of such advisers shall be full and complete protection in respect of
any action taken, omitted or suffered hereunder in good faith and without negligence and in accordance with the opinion of such advisers. 

11.9 The Agents shall be obliged to perform such duties and only such duties as are herein specifically set forth, and no implied duties or obligations
shall be read into this Agreement against the Agents. No Agent shall be under any obligation to take any action hereunder which it expects will result in any expense or liability of such Agent, the payment of which within a reasonable time is not,
in its opinion, assured to it. The obligations of the Agents hereunder are several and not joint. 

  
 6 

 11.10 The Agents, their affiliates and their respective officers and employees, in their individual or any
other capacity, may become the owner of, or acquire any interest in, any Notes with the same rights that the Agents would have it they were not the Agents hereunder.

Fiscal Agent, Registrar, Exchange Agent and Transfer Agent in its capacity as such may be removed at any time by the giving to it of at least 30 days’ written notice to that effect signed on behalf of the Issuer specifying the date on which
such removal shall become effective. Each of the Fiscal Agent, Registrar, Exchange Agent and Transfer Agent may at any time resign by giving at least 30 days’ written notice (unless the Issuer agrees to accept less notice) to that effect to the
Issuer specifying the date on which such resignation shall become effective. Notwithstanding the foregoing, no such resignation or removal shall take effect within 30 days before or after any due date for payment of any Notes or before a new Fiscal
Agent, Registrar, Exchange Agent and Transfer Agent, as the case may be, shall have been appointed by the Issuer as hereinafter provided, and such new Agent shall have accepted such appointment. Any change in any Agent shall be notified by the
Issuer to the other Agent(s). 
 12.2 The Issuer agrees with the Fiscal Agent that if, by the day falling 10 days before the expiry of any
notice under Clause 12.1 above, the Issuer has not appointed a replacement Fiscal Agent, then the Fiscal Agent shall be entitled, on behalf of the Issuer, to appoint in its place any reputable financial institution of good standing and the Issuer
shall not unreasonably object to such appointment. 
 12.3 Upon the effectiveness of the appointment of any successor Fiscal Agent, Registrar,
Exchange Agent and Transfer Agent, as the case may be, pursuant to Clause 12.1, the Fiscal Agent, Registrar, Exchange Agent and Transfer Agent so removed shall cease to be a Fiscal Agent, Registrar, Exchange Agent and Transfer Agent, as the case may
be, hereunder. Prior to the effectiveness of such appointment, the Fiscal Agent, Registrar, Exchange Agent and Transfer Agent shall hold all moneys deposited with it or held by it hereunder in respect of the Notes to the order of the respective

 nn. “Shares” shall mean shares of the Common Stock, any shares into which such Shares may be converted in accordance with Section 15 of the Plan and, to the extent a Participant
would not become subject to the adverse tax consequences under Code Section 409A, such other securities or property as may become subject to Awards pursuant to this Plan. 
 oo. “Tandem SAR” means a SAR that is granted in connection with a related Option pursuant to Section 7 herein, the exercise of which shall require forfeiture of the right to purchase
a Share under the related Option (and when a Share is purchased under the Option, the Tandem SAR shall similarly be canceled). 

pp. “Termination for Cause” shall mean termination of employment or service as a result of (i) any act or acts by
the Participant constituting a felony under any federal, state or local law; (ii) the Participant’s willful and continued failure to perform the duties assigned to him or her as an Eligible Individual; (iii) any material breach by the

 3. Shares Reserved. 

a. Maximum Shares. The maximum number of Shares available for Awards pursuant to the Plan effective as of the Company’s 2013
Annual Meeting of Shareholders shall be 13,976,324 Shares (or the number of shares of stock to which such Shares shall be adjusted as provided in Section 15 of the Plan), adjusted as follows: (i) reduced by one Share for every Share that
was subject to an Option or SAR granted after December 31, 2012 and two Shares for every one Share that was subject to an Award other than an Option or SAR granted after December 31, 2012 (with the same ratios applying to new Awards
granted after the Plan becomes effective, as applicable), and (ii) increased by one Share for every Share that was subject to an Option or SAR that becomes available after December 31, 2012, and two Shares for every one Share that was
subject to an Award other than an Option or SAR that becomes available after December 31, 2012 (as described in Section 3(b)). The number of Shares reserved for issuance under the Plan may be set aside out of authorized but unissued Shares
not reserved for any other purpose, or (to the extent permitted under applicable law) out of issued Shares acquired for and held in the treasury of the Company from time to time. 

b. Unissued Shares. Shares subject to, but not sold or issued under, any Award terminating, expiring, forfeited, settled in cash
or canceled for any reason, or tendered (either actually or by attestation) or withheld to satisfy tax withholding obligations with respect to an Award other than an Option or a SAR, shall again become available for Awards thereafter granted under
the Plan. To the extent such Shares become available after December 31, 2012, they shall become available hereunder as one Share for each such Share subject to Options and SARs and two Shares for each such Share subject to Awards other than
Options or SARs. 
 c. Acquisitions and Combinations. Awards made in assumption of, or in substitution or exchange for,
awards previously granted, or the right or obligation to make future awards, in each case by a company acquired by the Company or an Affiliate or with which the Company or an Affiliate combines shall not reduce the Shares available for Awards under
the Plan, nor shall such Shares again be available for Awards under the Plan as provided in Section 3(b). Additionally, in the event that a company acquired by the Company or an Affiliate or with which the Company or an Affiliate combines has
shares available under a pre-existing plan approved by shareholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent
appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or
combination) may be used for Awards under the Plan and shall not reduce the Shares available for Awards under the Plan; provided, however, that Awards using such available Shares shall not be made after the date awards or grants could have been made
under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Eligible Individuals prior to such acquisition or combination. 

  
 5 

 d. Shares Not Available for Awards. Notwithstanding anything to the contrary
contained in the Plan, none of the following Shares shall be added to the Shares available for Awards under the Plan: (i) Shares tendered by a Participant or withheld by the Company after December 31, 2012 in payment of the exercise price
of an Option, or to satisfy any tax withholding obligation with respect to Options or SARs, (ii) Shares subject to a SAR that are not issued upon exercise in connection with the stock settlement of the SAR after December 31, 2012, and
(iii) Shares reacquired by the Company on the open market or otherwise after December 31, 2012 using cash proceeds from the exercise of Options. 
 4. Award Limits. 
 Subject to adjustment as provided in
Section 15, no Participant may be granted (i) Options or SARs during any calendar year with respect to more than 1,000,000 Shares and (ii) Restricted Stock Awards and Restricted Stock Unit Awards during any calendar year that are
intended to comply with the performance-based exception under Code Section 162(m) and are denominated in Shares under which more than 1,000,000 Shares may be earned for each 12 months in the vesting period or Performance Period. During any
calendar year no Participant may be granted performance-based awards that are intended to comply with the performance-based exception under Code Section 162(m) and are denominated in cash under which more than may $2,000,000 may be earned for
each 12 months in the Performance Period. If an Award is cancelled, the cancelled Award shall continue to be counted toward the applicable limitation in this Section. Notwithstanding any other provision of the Plan to the contrary, the aggregate
grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all Awards granted to any Non-Employee Director during any single calendar year shall not exceed $500,000. 

5. Administration of the Plan. 
 a. Committee. The Plan shall be administered by a Committee designated by the Board to administer the Plan and consisting of not less than three Directors and subject to such terms and conditions
as the Board may prescribe. Members of the Committee who are eligible for Awards or have been granted Awards may vote on any matters affecting the administration of the Plan or the grant of any Awards pursuant to the Plan, except that no such member
shall act upon the granting of an Award to himself or herself, but any such member may be counted in determining the existence of a quorum at any meeting of the Committee during which action is taken with respect to the granting of Awards to him or
her. Each member of the Committee shall be (i) an “outside director” as defined in the Treasury regulations issued pursuant to Section 162(m) of the Code, (ii) a “non-employee director” as defined in
Rule 16b-3 promulgated under the Exchange Act and (iii) an “independent director” as defined in the Marketplace Rules of The NASDAQ Stock Market LLC. Members of the Committee shall serve for such period of time as the Board may
determine. From time to time the Board may increase the size of the Committee and appoint additional members thereto, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies however caused or remove
all members of the Committee and thereafter provide for members of the Board who meet the foregoing requirements of the Code, Rule 16b-3 and the Marketplace Rules to directly administer the Plan. Members of the Committee shall serve for such period
of time as the Board may determine. Notwithstanding the foregoing, in administering this Plan with respect to Awards for Non-Employee Directors, the Board shall exercise the powers of the Committee after obtaining the recommendation of the
Committee. 

  
 6 

 b. Authority. Subject to the provisions of the Plan, the Committee shall have the
authority in its sole discretion to: (i) determine the type or types of Awards (i.e., Incentive Stock Options, Nonstatutory Stock Options, SARs, Restricted Stock Awards, Restricted Stock Units or Cash-Based Awards) to be granted to each
Participant in the Plan, (ii) determine the Fair Market Value per Share in accordance with the terms of the Plan, (iii) determine the exercise price of Options to be granted to Eligible Individuals in accordance with the terms of the Plan,
(iv) determine the Eligible Individuals to whom, and the time or times at which, Awards shall be granted and the number of Shares subject to each Award, (v) prescribe, amend and rescind rules and regulations relating to the Plan, subject
to the limitations set forth in Section 17 of the Plan, (vi) determine the terms and provisions of each Award granted to Participants under the Plan and each Award Agreement (which need not be identical with the terms of other Awards and
Award Agreements) and, with the consent of the Participant, to modify or amend an outstanding Award Agreement; provided, however, that the Committee shall not have the authority to amend or adjust the exercise price of any Options
previously granted to a Participant under the Plan, whether through amendment, cancellation, replacement grant or otherwise, without the approval of the shareholders of the Company obtained in the manner provided in Section 16 of the Plan,
(vii) accelerate the exercise date of any Option or SAR, the vesting of any Restricted Stock Award, Restricted Stock Unit or the payment of any Cash-Based Award, (viii) determine whether any Participant will be required to execute a stock
purchase agreement or other agreement as a condition to the issuance of Shares pursuant to an Award, and to determine the terms and provisions of any such agreement (which need not be identical with the terms of any other such agreement) and, with
the consent of the Participant, to amend any such agreement, (ix) interpret the Plan or any agreement entered into with respect to the grant of Awards and the issuance of Shares upon exercise of Options, the vesting of Restricted Stock Units or
the payment of Cash-Based Awards, (x) determine the eligibility of an Eligible Individual for benefits hereunder and the amount thereof, (xi) authorize any person to execute on behalf of the Company any instrument required to effectuate
the grant of an Award previously granted or to take such other actions as may be necessary or appropriate with respect to the Company’s rights pursuant to Awards or agreements relating to the grant or exercise thereof and (xii) make such
other determinations and establish such other procedures as it deems necessary or advisable for the administration of the Plan. Further, the Committee shall not have the authority to amend or adjust Options or SARs previously granted to a
Participant under the Plan to (a) reduce the exercise price or Grant Price, (b) cancel the Options or SARs when the exercise price or Grant Price exceeds the Fair Market Value of the Shares in exchange for cash or another Award (other than
in accordance with Section 15 of the Plan), or (c) take any other action that would be treated as a repricing under the rules and regulations of the principal U.S. national securities exchange on which the Shares are traded, without the
approval of the shareholders of the Company obtained in the manner provided in Section 16 of the Plan. 
 c.
Determinations Final. All decisions, determinations and interpretations of the Committee shall be final and binding on all Participants and any other holders of any Awards granted under the Plan. 

d. Governance. The Committee shall keep minutes of its meetings and of the actions taken by it without a meeting. A majority of
the Committee shall constitute a quorum and the actions of a majority at a meeting, including a telephone meeting, at which a quorum is present or acts approved in writing by a majority of the members of the Committee without a meeting shall
constitute acts of the Committee. 

  
 7 

 e. Taxes. The Company shall pay all original issue and transfer taxes with respect to
the grant of Awards and/or the issue and transfer of Shares pursuant to the exercise of Options or SARs, the vesting of Restricted Stock Awards or Restricted Stock Units or the payment of Cash-Based Awards and all other fees and expenses necessarily
incurred by the Company in connection therewith; provided, however, that the person exercising an Option or SAR or to whom an Award is granted or to whom Shares are otherwise issued pursuant to the Plan shall be responsible for all
payroll, withholding, income and other taxes incurred by such person on the date of exercise of the Option or of issuance or vesting of Shares, as applicable. 
 6. Eligibility. 
 Awards may be granted under the Plan only to
Eligible Individuals; provided, however, that Consultants and Non-Employee Directors shall not be eligible to receive Incentive Stock Options. An Eligible Individual, who has been granted Awards may, if he or she is otherwise eligible,
be granted additional Awards. References in this Plan to “employment” and related terms (except for references to “employee” in the definition of “Employee”) shall include the providing of services as a Consultant or
Director. 
 7. Terms and Conditions of Options. 

Options granted pursuant to the Plan by the Committee shall be either Incentive Stock Options or Nonstatutory Stock Options and shall be
evidenced by an Option Agreement providing, in addition to such other terms as the Board may deem advisable, the following terms and conditions: 
 a. Time of Granting Options. The date of grant of an Option shall for all purposes be the date on which the Committee makes the determination granting such Option; provided, however,
that if the Committee determines that such grant shall be made as of some future date, the date of grant shall be such future date. Notice of the determination shall be given to each Participant within a reasonable time after the date of such grant.

 b. Number of Shares. Each Option Agreement shall state the number of Shares to which it pertains and whether such
Option is intended to constitute an Incentive Stock Option or a Nonstatutory Stock Option. Notwithstanding any provision in this Plan to the contrary, an Option that is intended to constitute an Incentive Stock Option may only be granted to an
Employee. 
 c. Exercise Price. The exercise price per Share for the Shares to be issued pursuant to the exercise of an
Option shall be such price as is determined by the Board; provided, however, that, other than in connection with Awards described in Section 3(c), such price shall in no event be less than 100% of the Fair Market Value per Share
on the date of grant of an Option. 
 In the case of any Incentive Stock Option granted to an Employee who at the time of grant
owns or is deemed to own (by reason of the attribution rules applicable under Section 424(d) of the Code or otherwise) stock possessing more than ten percent of the total combined voting power of all classes of stock of the Company, the
exercise price per Share shall be no less than 110% of the Fair Market Value per Share on the date of grant. 

  
 8 

 d. Medium and Time of Payment. The consideration to be paid for the Shares to be
issued upon exercise of an Option shall consist entirely of cash or check payable to the Company or such other consideration and method of payment permitted under any laws to which the Company is subject and which is approved by the Committee,
including without limitation (i) in the case of an Eligible Individual other than an executive officer or a Director, by delivery of a promissory note, (ii) by tendering previously acquired Shares (valued at Fair Market Value as of
the date of tender) that have been owned for a period of at least six months (or such other period as is necessary to avoid accounting charges against the Company’s earnings), (iii) if Shares are traded on a national securities exchange or
NASDAQ, through the delivery of irrevocable instructions to a broker to deliver promptly to the Company an amount equal to the exercise price, (iv) by withholding Shares otherwise issuable in connection with the Option, or (v) any
combination of (i), (ii), (iii) and (iv). In connection with all exercises of Options and regardless of the medium of payment, the Participant shall pay in cash any amount necessary to satisfy the Company’s withholding obligations.

 e. Term of Options. The term of each Option may be up to seven years from the date of grant thereof; provided,
however, that the term of an Incentive Stock Option granted to an Employee who, at the time the Incentive Stock Option is granted, owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) stock
possessing more than ten percent of the total combined voting power of all classes of stock of the Company, shall be five years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. The term of any Option
may be less than the maximum term provided for herein as specified by the Committee upon grant of the Option and as set forth in the Option Agreement. Notwithstanding the foregoing, in the event that on the last business day of the term of an
Option, other than an Incentive Stock Option, (i) the exercise of the Option is prohibited by applicable law or (ii) Shares may not be purchased or sold by certain Eligible Individuals due to the “black-out period” of a Company
policy or a “lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Option shall be extended for a period of thirty (30) days following the end of the legal prohibition, black-out
period or lock-up agreement. 
 f. Form of Settlement. In its sole discretion, the Committee may provide that the Shares
to be issued upon an Option’s exercise shall be in the form of Restricted Stock or other similar securities. 
 g.
Maximum Amount of Incentive Stock Options. To the extent that the aggregate Fair Market Value (determined at the time an Incentive Stock Option is granted) of the Shares with respect to which Incentive Stock Options are exercisable for the
first time by a Participant during any calendar year under all incentive stock option plans of the Company exceeds $100,000, the Options in excess of such limit shall be treated as Nonstatutory Stock Options. 

h. Prohibition of Dividends and Dividend Equivalents. No Option may provide for the payment of dividends or Dividend Equivalents.

 8. Exercise of Option. 
 a. In General. Any Option granted hereunder to a Participant shall be exercisable at such times and under such conditions as may be determined by the Committee and as shall be permissible under the
terms of the Plan, including any performance criteria with respect to the Company and/or the Participant as may be determined by the Committee. 

  
 9 

 An Option may be exercised in accordance with the provisions of the Plan as to all or any
portion of the Shares then exercisable thereunder from time to time during the term of the Option. However, an Option may not be exercised for a fraction of a Share. 
 b. Procedure. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company at its principal business office in accordance with the terms of the
Option Agreement by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company, together with (i) any other agreements required by the terms of the
Plan and/or Option Agreement or as required by the Committee and (ii) payment by the Participant of all payroll, withholding or income taxes incurred in connection with such Option exercise (or arrangements for the collection or payment of such
tax satisfactory to the Board are made). 
 c. Exercise of Shareholder Rights. Until the Option is properly exercised in
accordance with the terms of this Section 8, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock. No adjustment shall be made for a dividend or other right for which the
record date is prior to the date the Option is exercised except as provided in Section 15 of the Plan. 
 d. Termination
of Eligibility; Non-Director Awards. If a Participant who is not a Director ceases to serve as an Employee or Consultant, as applicable, for any reason other than death or permanent and total disability (within the meaning of
Section 22(e)(3) of the Code) or Termination for Cause and thereby terminates his or her Continuous Status as an Eligible Individual, he or she may, but only within 90 days following the date he or she ceases his or her Continuous Status as an
Eligible Individual (subject to any earlier termination of the Option as provided by its terms), exercise his or her Option to the extent that he or she was entitled to exercise it at the date of such termination. To the extent that he or she was
not entitled to exercise the Option at the date of such termination, or if he or she does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. Notwithstanding anything to
the contrary herein, the Committee may at any time and from time to time prior to the termination of a Nonstatutory Stock Option, with the consent of the Participant, extend the period of time during which the Participant may exercise his or her
Nonstatutory Stock Option following the date he or she ceases his or her Continuous Status as an Eligible Individual; provided, however, that the maximum period of time during which a Nonstatutory Stock Option shall be exercisable
following the date on which a Participant terminates his or her Continuous Status as an Eligible Individual shall not exceed the original term of such Option as set forth in the Option Agreement and that notwithstanding any extension of time during
which a Nonstatutory Stock Option may be exercised, such Option, unless otherwise amended by the Committee, shall only be exercisable to the extent the Participant was entitled to exercise the Option on the date he or she ceased his or her
Continuous Status as an Eligible Individual; provided, further, that no extension shall be made at any time where the exercise price per Share of such Option is less than the Fair Market Value of one Share at the time of such proposed extension,
unless it is determined that such extension will not cause the Participant to incur additional tax and interest charges upon exercise of such Option under Section 409A of the Code. 

  
 10 

 e. Death or Disability of Participant; Non-Director Awards. If the Continuous Status
as an Eligible Individual of a Participant who is not a Director ceases due to death or permanent and total disability (within the meaning of Section 22(e)(3) of the Code) of the Participant, the Option may be exercised within 180 days (or such
other period of time not exceeding one year as is determined by the Committee at the time of granting the Option) following the date of death or termination of employment due to permanent or total disability (subject to any earlier termination of
the Option as provided by its terms), by the Participant in the case of permanent or total disability, or in the case of death by the Participant’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance,
but in any case (unless otherwise determined by the Committee at the time of granting the Option) only to the extent the Participant was entitled to exercise the Option at the date of his or her termination of employment by death or permanent and
total disability. To the extent that he or she was not entitled to exercise such Option at the date of his or her termination of employment by death or permanent and total disability, or if he or she does not exercise such Option (which he or she
was entitled to exercise) within the time specified herein, the Option shall terminate. Notwithstanding anything to the contrary herein, the Committee may at any time and from time to time prior to the termination of a Nonstatutory Stock Option,
with the consent of the Participant, extend the period of time during which the Participant may exercise his or her Nonstatutory Stock Option following the date he or she ceases his or her Continuous Status as an Eligible Individual;
provided, however, that the maximum period of time during which a Nonstatutory Stock Option shall be exercisable following the date on which a Participant terminates his or her Continuous Status as an Eligible Individual shall not
exceed the original term of such Option as set forth in the Option Agreement and that notwithstanding any extension of time during which a Nonstatutory Stock Option may be exercised, such Option, unless otherwise amended by the Committee, shall only
be exercisable to the extent the Participant was entitled to exercise the Option on the date he or she ceased his or her Continuous Status as an Eligible Individual; provided, further, that no extension shall be made at any time where the exercise
price per Share of such Option is less than the Fair Market Value of one Share at the time of such proposed extension, unless it is determined that such extension will not cause the Participant to incur additional tax and interest charges upon
exercise of such Option under Section 409A of the Code. 
 f. Termination of Eligibility; Director Awards. The
preceding Sections 8(d) and 8(e) shall not apply with respect to a Participant’s Awards to the extent such Awards were made to the Participant in his or her capacity as a Director. If a Participant ceases to be a Director for any reason other
than Termination for Cause, he or she (or his or her beneficiary or representative in the event of termination of service as a result of death or permanent and total disability) may exercise his or her Option through its original expiration date to
the extent that the Option was vested and he or she was entitled to exercise the Option on the date of such termination of service as a Director. To the extent that he or she was not entitled to exercise the Option at the date of such termination of
service, or if he or she (or his or her beneficiary or representative in the event of termination of service as a result of death or permanent and total disability) does not exercise the Option (which he or she was entitled to exercise) within the
time specified herein (i.e., prior to its expiration date), the Option shall terminate. 
 g. Termination for Cause. If a
Participant’s Continuous Status as an Eligible Individual with the Company terminates due to his or her Termination for Cause, he or she shall immediately forfeit all outstanding Options. 

  
 11 

 h. Expiration of Option. Notwithstanding any provision in the Plan, including but not
limited to the provisions set forth in Sections 8(d), 8(e) and 8(f), an Option may not be exercised, under any circumstances, after the expiration of its term. 
 i. Conditions on Exercise and Issuance. As soon as practicable after any proper exercise of an Option in accordance with the provisions of the Plan, the Company shall (i) deliver to the
Participant at the principal executive office of the Company or such other place as shall be mutually agreed upon between the Company and the Participant, a certificate or certificates representing the Shares for which the Option shall have been
exercised or (ii) otherwise arrange for such Shares to be issued to the Participant. The time of issuance and, if applicable, delivery of the certificate or certificates representing the Shares for which the Option shall have been exercised may
be postponed by the Company for such period as may be required by the Company, with reasonable diligence, to comply with any law or regulation applicable to the issuance or delivery of such Shares. 

Options granted under the Plan are conditioned upon the Company obtaining any required permit or order from the appropriate governmental
agencies authorizing the Company to issue such Options and Shares issuable upon exercise thereof. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares
pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act, the Exchange Act, applicable state law, the rules and regulations promulgated thereunder and the requirements of the Marketplace
Rules of The NASDAQ Stock Market LLC and any stock exchange upon which the Shares may then be listed. Any such issuance may be further subject to the approval of counsel for the Company with respect to such compliance. 

9. Terms and Conditions of Restricted Stock Awards. 

a. Grant. Restricted Stock Awards may be granted hereunder by the Committee to Eligible Individuals either alone or in addition to
other Awards granted under the Plan. A Restricted Stock Award shall be subject to such terms and conditions as may be determined by the Committee and may be subject to vesting conditioned upon the satisfaction of such requirements, conditions (such
as a condition that the Participant’s right to the Shares shall vest in installments over a period of time during which services are to be provided to the Company by the Eligible Individual), restrictions or performance criteria as shall be
established by the Committee and set forth in the Award Agreement. During any period during which Shares acquired pursuant to a Restricted Stock Award are subject to vesting conditions, such Shares may not be sold, exchanged, transferred, pledged,
assigned or otherwise disposed of by the Participant. The provisions of Restricted Stock Awards need not be the same with respect to each Participant receiving such awards. The Committee has absolute discretion to determine whether any consideration
is to be received by the Company as a condition precedent to the issuance of Restricted Stock Awards. The terms of any Restricted Stock Award granted under this Plan shall be set forth in an Award Agreement which shall contain provisions determined
by the Committee which are not inconsistent with the Plan. 
 b. Rights of Holders of Restricted Stock. Beginning on the
date of grant of a Restricted Stock Award and subject to execution of the Award Agreement, the Participant shall become a shareholder of the Company with respect to all Shares subject to the Restricted Stock Award and shall have all of the rights of
a shareholder, including the right to vote the Shares subject to the Restricted Stock Award and the right to receive distributions made with respect to such Shares; 

  
 12 

 
provided, however, that any Shares, any other property or cash distributed as a dividend or otherwise with respect to any such Shares as to which the restrictions have not yet
lapsed shall be subject to the same restrictions as the Shares subject to the Restricted Stock Award; provided further, that the provisions of Section 13(d) shall apply with respect to dividends on Restricted Stock which is
subject to performance-based vesting conditions. 
 c. Delivery of Shares. Shares issued upon the
grant of Restricted Stock Awards shall, unless otherwise determined by the Committee, be maintained in the custody of or on behalf of the Company until all applicable vesting conditions have been satisfied. Shares subject to Restricted Stock Awards
that are no longer subject to restrictions shall be delivered to the Participant promptly after the applicable restrictions lapse or are waived. Notwithstanding anything to the contrary set forth herein, but subject to Section 19(j) hereof,
delivery of Shares pursuant to a Restricted Stock Award shall be made no later than 2 1/2 months after the close of the Company’s first taxable year in which such Shares are no longer subject to a
substantial risk of forfeiture (within the meaning of Section 409A of the Code). 
 d. Termination of Continuous
Status as an Eligible Individual. Unless otherwise determined by the Committee or unless otherwise provided in the Award Agreement evidencing the Award, in the event of the termination of a Participant’s Continuous Status as an Eligible
Individual, Shares which are subject to a Participant’s Restricted Stock Award which are not vested as of the date of such termination shall be automatically forfeited by the Participant and cancelled by the Company for no value. 

e. Waiver of Forfeiture. The Committee may, when it finds that a waiver would be in the best interests of the Company and subject
to such terms and conditions as the Committee shall deem appropriate, waive in whole or in part any remaining vesting restrictions with respect to any Restricted Stock Award or any other conditions set forth in any Award Agreement, subject to the
limitations imposed under Section 162(m) of the Code and the regulations thereunder in the case of a Restricted Stock Award intended to comply with the performance-based compensation exception under Code Section 162(m) except as otherwise
determined by the Committee to be appropriate under the circumstances. 
 10. Terms and Conditions of Restricted Stock
Units. 
 a. Grant. Restricted Stock Units may be issued hereunder to Eligible Individuals either alone or in
addition to other Awards granted under the Plan. A Restricted Stock Unit is a bookkeeping entry that represents the right to receive one Share to be issued and delivered at the end of the applicable vesting period, subject to a risk of cancellation
and to the other terms and conditions set forth in the Plan and in any Award Agreement evidencing the Restricted Stock Unit and subject to any additional terms and conditions established by the Committee. The Company shall establish and maintain
accounts for Participants in which the Company shall record Restricted Stock Units and the transactions and events affecting such units. Restricted Stock Units and other items reflected in the account will represent only bookkeeping entries by the
Company to evidence the Company’s unfunded obligations. The provisions of Restricted Stock Units need not be the same with respect to each Participant receiving such Awards. The Committee has absolute discretion to determine whether any
consideration is to be received by the Company as a condition precedent to the grant of a Restricted Stock Unit. The terms of any Restricted Stock Unit granted under this Plan shall be set forth in an Award Agreement which shall contain provisions
determined by the Committee which are not inconsistent with the Plan. 

  
 13 

 b. Rights of Holders of Restricted Stock Units; Dividend Equivalents. Unless the
Committee otherwise provides in an Award Agreement for Restricted Stock Units, any Participant holding Restricted Stock Units shall have no rights as a shareholder of the Company with respect to such Restricted Stock Units. The Committee shall be
authorized to establish procedures pursuant to which the Company’s payment of any Restricted Stock Unit may be deferred in a manner that would not trigger the adverse tax consequences under Code Section 409A. Subject to the provisions of
the Plan and any Award Agreement, the recipient of a Restricted Stock Unit may, if so determined by the Committee, be entitled to receive, currently (or on a deferred basis, but in such a case subject to the same vesting restrictions as the
Restricted Stock Unit to which such dividend relates, with such deferral to last no longer than the vesting period to which such Restricted Stock Unit is subject) and with respect to the number of Shares covered by the Award, payments
(“Dividend Equivalents”) in amounts equivalent to cash, stock or other property paid by the Company as dividends on the Company’s Common Stock prior to the vesting of the Restricted Stock Units in a manner that would not trigger the
adverse tax consequences under Code Section 409A; provided, however, that the provisions of Section 13(d) shall apply with respect to Dividend Equivalents on Restricted Stock Units which are subject to performance-based
vesting conditions. 
 c. Delivery of Shares in Settlement of Restricted Stock Units. Restricted
Stock Units (if not previously cancelled) will be automatically settled on or about the vesting date or dates set forth in the Award Agreement evidencing the Award. The Company may make delivery of Shares in settlement of Restricted Stock Units by
either delivering one or more stock certificates representing such Shares to the Participant, registered in the name of the Participant, or by depositing such Shares into an account maintained for the Participant and established in connection with
any Company plan or arrangement providing for investment in Common Stock of the Company. Notwithstanding anything to the contrary set forth herein, but subject to Section 19(j), delivery of Shares pursuant to a Restricted Stock Unit shall be
made no later than 2 1/2 months after the close of the Company’s first taxable year in which such Shares are no longer subject to a substantial risk of forfeiture (within the meaning of Section 409A of the Code).

 d. Termination of Continuous Status as an Eligible Individual. Unless otherwise determined by the Committee or
unless otherwise provided in the Award Agreement evidencing the Award, in the event of the termination of a Participant’s Continuous Status as an Eligible Individual, the Participant’s Restricted Stock Units which are not vested as of the
date of such termination shall not vest and shall automatically be cancelled for no value and without issuance of any Shares. 

e. Waiver of Forfeiture. The Committee may, when it finds that a waiver would be in the best interests of the Company and subject
to such terms and conditions as the Committee shall deem appropriate, waive in whole or in part any remaining vesting restrictions with respect to any Restricted Stock Units or any other conditions set forth in any Award Agreement, subject to the
limitations imposed under Section 162(m) of the Code and the regulations thereunder in the case of a Restricted Stock Unit intended to comply with the performance-based compensation exception under Code Section 162(m) except as otherwise
determined by the Committee to be appropriate under the circumstances.

 11. Share Appreciation Rights. 

a. Grant of SARs. Subject to the terms and conditions of the Plan, SARs may be granted to Participants at any time and from time to
time as shall be determined by the Committee. The Committee may grant Freestanding SARs, Tandem SARs or any combination of Freestanding and Tandem SARs. 
 Subject to the terms and conditions of the Plan, the Committee shall have complete discretion in determining the number of SARs granted to each Participant and, consistent with the provisions of the Plan,
in determining the terms and conditions pertaining to such SARs. 
 The Grant Price for each SAR shall be determined by the
Committee and shall be specified in the SAR Award Agreement. The Grant Price shall not be less than 100% of the Fair Market Value per Share on the date of grant except in the case of Awards described in Section 3(c). 

b. SAR Award Agreement. Each SAR Award shall be evidenced by a SAR Award Agreement that shall specify the Grant Price, the term of
the SAR, and such other provisions as the Committee shall determine in its sole discretion and which are not inconsistent with this Plan. No SAR may provide for the payment of dividends or Dividend Equivalents. 

c. Term of SAR. The term of a SAR granted under the Plan may be up to seven years from the date of grant thereof. The term of any
SAR may be less than the maximum term provided for herein as specified by the Committee upon grant of the SAR and as set forth in the SAR Award Agreement. Notwithstanding the foregoing, in the event that on the last business day of the term of a SAR
(i) the exercise of the SAR is prohibited by applicable law or (ii) Shares may not be purchased or sold by certain Eligible Individuals due to the “black-out period” of a Company policy or a “lock-up” agreement
undertaken in connection with an issuance of securities by the Company, the term shall be extended for a period of thirty (30) days following the end of the legal prohibition, black-out period or lock-up agreement. 

d. Exercise of Freestanding SARs. Freestanding SARs may be exercised upon whatever terms and conditions the Committee, in its sole
discretion, imposes. 
 e. Exercise of Tandem SARs. Tandem SARs may be exercised for all or part of the Shares subject to
the related Option upon the surrender of the right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable. 

Notwithstanding any other provision of this Plan to the contrary, with respect to a Tandem SAR: (a) the Tandem SAR will expire no
later than the expiration of the underlying Option; (b) the exercise of the Tandem SAR may not have economic and tax consequences more favorable than the exercise of the Option followed by an immediate sale of the underlying Shares, and the
value of the payout with respect to the Tandem SAR may be for no more than 100% of the excess of the Fair Market Value of the Shares subject to the underlying Option at the time the Tandem SAR is exercised over the exercise price of the
underlying Option; (c) the Tandem SAR may be exercised only when the Fair Market Value of the Shares subject to the Option exceeds the exercise price of the Option; (d) the Tandem SAR may be exercised only when the underlying Option is
eligible to be exercised; and (e) the Tandem SAR is transferable only when the underlying Option is transferable, and under the same conditions. 

  
 15 

 f. Payment of SAR Amount. SARs granted under this Plan shall be payable in Shares,
cash or such other property as may be designated by the Committee. Upon the exercise of a SAR, a Participant shall be entitled to receive from the Company such number of Shares (or, in the case of SARs exercisable for cash or other property, cash or
property with a value equal to the fair market value of such number of Shares on the date of exercise) determined by multiplying: 
  

	 	(i)	The excess of the Fair Market Value of a Share on the date of exercise over the Grant Price; by 

 

	 	(ii)	The number of Shares with respect to which the SAR is exercised. 

 Such product shall then be divided by the Fair Market Value of a Share on the date of exercise. The resulting number (rounded down to the next whole number) is the number of Shares to be issued to the
Participant upon exercise of a SAR. 
 g. Termination of Continuous Status as an Eligible Individual. Each SAR Award
Agreement shall set forth the extent to which the Participant shall have the right to exercise the SAR following termination of the Participant’s employment with or provision of services to the Company. Such provisions shall be determined in
the sole discretion of the Committee, shall be included in the SAR Award Agreement entered into with Participants, need not be uniform among all SARs issued pursuant to this Plan, and may reflect distinctions based on the reasons for termination.

 h. Other Restrictions. The Committee shall impose such other conditions and/or restrictions on any Shares
received upon exercise of a SAR granted pursuant to the Plan as it may deem advisable or desirable. These restrictions may include, but shall not be limited to, a requirement that the Participant hold the Shares received upon exercise of a SAR for a
specified period of time. 
 12. Cash-Based Awards. 

Cash-Based Awards may be granted hereunder by the Committee to Eligible Individuals either alone or in addition to other Awards granted
under the Plan. A Cash-Based Award shall be subject to such terms and conditions as may be determined by the Committee, and shall be subject to the satisfaction of such requirements (such as a requirement that the Participant’s right to payment
of the Cash-Based Award shall be contingent on the provision of services for the Company over a specified period of time and/or employment on a specified date) and performance criteria (which may be based upon the criteria set forth in
Section 13(b)) as shall be established by the Committee and set forth in the Award Agreement (or, if applicable, in a resolution duly adopted by the Committee). Cash-Based Awards granted under this Plan shall be payable in cash or, if
designated by the Committee, Shares or such other property with a fair market value on the date of payment equal to the cash amount payable under Cash-Based Award. Notwithstanding anything to 

  
 16 

 
the contrary set forth herein, payment of a Cash-Based Award shall be made no later than 2 1/2 months after the close of the Company’s first taxable year in which such
Cash-Based Award is no longer subject to a substantial risk of forfeiture (within the meaning of Section 409A of the Code). 
 13. Code Section 162(m) Provisions. 
 a. Application
to Covered Employee. Notwithstanding any other provision of the Plan, if the Committee determines at the time Restricted Stock, a Restricted Stock Unit Award or a Cash-Based Award is granted to a Participant that such Participant is, or is
likely to be as of the end of the tax year in which the Company would claim a tax deduction in connection with such Award, a “covered employee” within the meaning of Section 162(m)(3) of the Code, then the Committee may qualify such
an Award as “performance-based compensation” pursuant to Section 162(m) of the Code. The Committee has complete discretion concerning whether a particular Award should be qualified as “performance-based compensation.” If the
Committee determines that a particular Award should qualify as “performance-based compensation,” the provisions of this Section 13, to the extent applicable, shall control over any contrary provision in the Plan. 

b. Performance Goals. Restricted Stock, Restricted Stock Unit Awards and Cash-Based Awards may be made subject to the achievement
of performance goals established by the Committee relating to one or more business criteria (the “Performance Criteria”) pursuant to Section 162(m) of the Code. Performance Criteria may be applied to the Company, an Affiliate,
division, business unit or individual or any combination thereof and may be measured in absolute levels or relative to another company or companies, a peer group, an index or indices or Company performance in a previous period. Performance may be
measured annually or cumulatively over a longer period of time. Performance Criteria that may be used to establish performance goals are: revenue; operating income or net operating income; orders, return on equity; return on assets or net assets;
cash flow; share price performance; return on capital; earnings; earnings per share; shareholder return and/or value (including but not limited to total shareholder return); economic value added; economic profit; ratio of operating earnings to
capital spending; EBITDA; EBIT; costs; operating earnings; gains; product development; client development; leadership; project progress; project completion; increase in total revenues; net income; operating cash flow; net cash flow; retained
earnings; budget achievement; return on capital employed; return on invested capital; cash available to Company from a subsidiary or subsidiaries; expense spending; gross margin; net margin; market capitalization; customer satisfaction; financial
return ratios; market share; operating profits (including earnings before or after income taxes, depreciation and amortization); net profits; earnings per share growth; profit returns and margins; stock price; working capital; business trends;
production cost; project milestones; capacity utilization; quality; economic value added; operating efficiency; diversity; debt; dividends; bond ratings; corporate governance; and health and safety. The Committee may provide for exclusion of the
impact of an event or occurrence which the Committee determines should appropriately be excluded, including (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (ii) an event either
not directly related to the operations of the Company, Affiliate, division, or business unit or not within the reasonable control of management, or (iii) the cumulative effects of tax or accounting changes in accordance with U.S. generally
accepted accounting principles. The performance goals for each Participant (including any exclusions described in the preceding sentence, if applicable) and the amount payable if those goals are met shall be established in writing for each specified
period of performance by the Committee no later than 90 days after the commencement of the period of 

  
 17 

 
service to which the performance goals relate and while the outcome of whether or not those goals will be achieved is substantially uncertain. However, in no event will such goals be established
after 25% of the period of service to which the goals relate has elapsed. The performance goals shall be objective. Such goals and the amount payable for each performance period if the goals are achieved shall be set forth in the applicable Award
Agreement. No amounts shall be payable to any Participant for any performance period unless and until the Committee certifies that the performance goals and any other material terms were in fact satisfied. 

c. Adjustment of Payment. Notwithstanding any provision of the Plan, with respect to any Award that is subject to this Section,
the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance goals except in the case of the death or disability of the Participant or
as otherwise determined by the Committee in special circumstances to the extent permitted under Section 162(m) of the Code and the Treasury regulations issued pursuant thereto. 

d. Dividends and Dividend Equivalents. Dividends and Dividend Equivalents on Restricted Stock and Restricted Stock Units that are
subject to performance-based vesting conditions and/or Section 13 shall, notwithstanding the provisions of Sections 9(b) and 10(b) of the Plan, either (i) not be paid or credited or (ii) if provided in the Award Agreement, be
accumulated and subject to achievement of the performance goals to the same extent as the Restricted Stock or Restricted Stock Units. 
 e. Other Restrictions. The Committee shall have the power to impose such other restrictions on Awards subject to this Section as it may deem necessary or appropriate to ensure that such Awards
satisfy all requirements for “performance-based compensation” within the meaning of Section 162(m)(4)(C) of the Code, or any successor provision thereto. 
 14. Nontransferability of Awards. 
 Except as otherwise
provided in a Participant’s Award Agreement or otherwise determined at any time by the Committee in accordance with this Section 14, no Awards granted under the Plan, and no Shares subject to any such Awards, that have not been issued or
as to which any applicable vesting restriction, performance or deferral period has not lapsed, may be sold, pledged, assigned, hypothecated, gifted, transferred or disposed of in any manner, either voluntarily or involuntarily by operation of law,
other than by will or by the laws of descent or distribution or transfers between spouses incident to a divorce. Furthermore, except as otherwise provided in a Participant’s Award Agreement or otherwise determined at any time by the Committee,
Options and SARs may be exercised during the life of the Participant only by the Participant or the Participant’s guardian or legal representative. Notwithstanding the foregoing, a Participant may assign or transfer an Award (other than an
Incentive Stock Option) with the consent of the Committee (each transferee thereof, a “Permitted Transferee”), which consent may be granted or withheld in the Committee’s sole discretion, provided that such Permitted Transferee shall
be bound by and subject to all of the terms and conditions of the Plan and the Award Agreement relating to the transferred Award and shall execute an agreement satisfactory to the Company evidencing such obligations; and, provided further, that such
Participant shall remain bound by the terms and conditions of the Plan. The Company shall cooperate with any Permitted Transferee and the Company’s transfer agent in effectuating any transfer permitted under this Section 14. With respect
to those Awards, if any, that 

  
 18 

 
are permitted to be transferred to another individual, references in the Plan to exercise of the Award by the Participant or payment of any amount or issuance of any Shares to the Participant
shall be deemed to include the Participant’s Permitted Transferee. In no event may an Award be transferred hereunder for consideration, and in no event may a Permitted Transferee be other than (i) the Participant’s spouse, children or
grandchildren (including any adopted and step children or grandchildren), parents, grandparents or siblings, (ii) a trust for the benefit of one or more of the Participant or the persons referred to in clause (i), (iii) a partnership,
limited liability company or corporation in which the Participant or the persons referred to in clause (i) are the only partners, members or shareholders or (iv) a charitable organization. 

15. Adjustment upon Change in Corporate Structure. 

a. Corporate Transaction. In the event of any stock split, reverse stock split, merger, reorganization, consolidation,
recapitalization, combination or distribution (whether in cash, Shares or other property, other than a regular cash dividend), spin-off or similar transaction or any other change in corporate structure affecting the Shares or value thereof, such
adjustment and other substitutions shall be made to the Plan and to Awards in a manner the Committee deems equitable or appropriate taking into consideration the accounting and tax consequences, including such adjustments in the aggregate number,
class and kind of securities that may be delivered under the Plan, the limitations in Section 4 (other than to Awards denominated in cash), the maximum number of Shares that may be issued pursuant to Incentive Stock Options and, in the
aggregate or to any Participant, in the number, class, kind and option or exercise price of securities subject to outstanding Awards granted under the Plan (including, if the Committee deems appropriate, the substitution of similar options to
purchase the shares of, or other awards denominated in the shares of, another company). Any such adjustment shall be determined in good faith by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential
benefits intended to be made available under the Plan, and the Committee’s determination in that respect shall be final, binding and conclusive. 
 b. Dissolutions/Liquidation. In the event of the dissolution or liquidation of the Company, or in the event of a sale of all or substantially all of the assets of the Company (other than in the
ordinary course of business), or the merger or consolidation of the Company with or into another corporation, as a result of which the Company is not the surviving and controlling corporation, the Board shall, to the extent such action would not
trigger the adverse tax consequences under Code Section 409A, (i) make provision for the assumption of outstanding Awards by the successor corporation, (ii) declare that any Option shall terminate as of a date fixed by the Board which
is at least 30 days after the notice thereof to the Participant and shall give each Participant the right to exercise his or her Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be
exercisable provided such exercise does not violate Section 8(i) of the Plan, (iii) accelerate the vesting of Restricted Stock Awards, Restricted Stock Units and the payment of Cash-Based Awards, or (iv) cause any Award outstanding as
of the effective date of any such event to be cancelled in consideration of a cash payment or grant of an alternative option or award (whether by the Company or any entity that is a party to the transaction), or a combination thereof, to the holder
of the cancelled Award, provided that such payment and/or grant are substantially equivalent in value to the fair market value of the cancelled Award as determined by the Committee. 

  
 19 

 c. Fractional Shares. No fractional shares of Common Stock shall be issuable on
account of any action aforesaid, and the aggregate number of shares into which Shares then covered by an Award, when changed as the result of such action, shall be reduced to the largest number of whole shares resulting from such action, unless the
Board, in its sole discretion, shall determine to issue scrip certificates in respect to any fractional shares, which scrip certificates shall be in a form and have such terms and conditions as the Board in its discretion shall prescribe.

 d. Tax Considerations. Any adjustment or action taken by the Board pursuant to this Section 15 shall be carried
out in accordance with Code Section 424, if applicable, and only if such action would not trigger the adverse consequences of Code Section 409A. 
 16. Shareholder Approval. 
 Effectiveness of this Plan is
subject to approval by the shareholders of the Company within 12 months before or after the date the Plan was initially adopted by the Board; provided, however, that Options may be granted pursuant to the Plan subject to subsequent
approval of the Plan by such shareholders. Any Option exercised before shareholder approval was obtained can be rescinded if shareholder approval is not obtained within 12 months before or after the Plan was adopted by the Board. Shareholder
approval of the Plan or any amendment thereto required to be approved by the shareholders of the Company shall be obtained (i) by the affirmative vote of the holders of a majority of the Shares present or represented and entitled to vote
thereon at a meeting of shareholders duly held in accordance with the laws of the State of California or (ii) by written consent of the holders of the outstanding Shares having not less than the minimum number of votes that would be necessary
to authorize the approval at a meeting of the shareholders duly held in accordance with the laws of the State of California. 

17. Amendment and Termination of the Plan. 
 a. Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable, subject to any requirement for shareholder approval
imposed by applicable law, including the rules and regulations of The NASDAQ Stock Market LLC or any stock exchange on which Shares are listed or quoted, and shall make any amendments which may be required so that Options intended to be Incentive
Stock Options shall at all times continue to be Incentive Stock Options for the purpose of Section 422 of the Code; provided, however, that the Board may not amend the Plan in any manner that would result in noncompliance with
Rule 16b-3 of the Exchange Act; provided, further, that without approval of the Company’s shareholders, no such revision or amendment shall (i) materially increase the benefits accruing to Participants under the Plan;
(ii) increase the number of Shares which may be issued under the Plan, other than in connection with an adjustment under Section 15 of the Plan; (iii) materially modify the requirements as to eligibility for participation in the Plan;
(iv) materially change the designation of the class of Eligible Individuals eligible to be granted Awards; (v) remove the administration of the Plan from the Board or its Committee; (vi) extend the term of the Plan beyond the maximum
term set forth in Section 20 hereunder; (vii) eliminate the requirements relating to minimum exercise price, minimum Grant Price and shareholder approval, (viii) increase the maximum permissible term of any Option, (ix) add
performance goals to Section 13(b) or (x) increase the limitation in Section 4. Further, no revision or amendment shall, without the approval of the Company’s shareholders, cancel Options or SARs in exchange for cash when the

  
 20 

 
exercise price or Grant Price per Share exceeds the Fair Market Value of the Shares or take any action with respect to Options or SARs that would be treated as a repricing under the rules and
regulations of the principal U.S. securities exchange on which the Shares are traded, including a reduction of the exercise price or Grant Price of Options or SARs and the exchange of Options or SARs for other Awards (or amend the provisions of
Section 5(b) relating to such actions by the Committee). 
 b. Effect of Amendment or Termination. Except as
otherwise provided in Section 15 of the Plan, and except to the extent necessary to avoid the imposition of additional tax and/or interest under Code Section 409A with respect to Awards that are treated as nonqualified deferred
compensation, any amendment or termination of the Plan shall not affect Awards already granted, and such Awards shall remain in full force and effect as if the Plan had not been amended or terminated, unless mutually agreed otherwise between the
Participant and the Company, which agreement must be in writing and signed by the Participant and the Company. Notwithstanding anything to the contrary herein, this Plan shall not adversely affect, unless mutually agreed in writing by the Company
and a Participant, the terms and provisions of any Award granted prior to the date the Plan was approved by shareholders as provided in Section 16 of the Plan. 
 18. Indemnification. 
 No member of the Board or its Committee
shall be liable for any act or action taken, whether of commission or omission, except in circumstances involving willful misconduct, or for any act or action taken, whether of commission or omission, by any other member or by any officer, agent or
Employee. In addition to such other rights of indemnification they may have as members of the Board, or as members of the Committee, the Board and the Committee shall be indemnified by the Company against reasonable expenses, including
attorneys’ fees actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken, by
commission or omission, in connection with the Plan or any Award granted thereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by
them in satisfaction of a judgment in any action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that a Board or Committee member is liable for willful misconduct in the
performance of his or her duties; provided that within 60 days after institution of any such action, suit or proceeding, such Board or Committee member shall in writing have offered the Company the opportunity, at its own expense, to handle and
defend the same. The payment of any amount in satisfaction of the indemnification right described in this Section 18 shall occur no later than the last day of the taxable year following the taxable year in which the expenses were incurred. Any
right to such indemnification shall not be subject to liquidation or exchange for another benefit, and no such indemnification in any taxable year shall in any way affect the expenses eligible for reimbursement or indemnification, or in-kind
benefits to be provided, in any other taxable year. 
 19. General Provisions. 

a. Withholding or Deduction for Taxes. The grant of Awards hereunder and the issuance of Shares and all payments and distributions
pursuant to this Plan are conditioned upon the Company’s reservation of the right to withhold, in accordance with any applicable law, from any 

  
 21 

 
compensation or other amounts payable to the Participant (or Permitted Assignee), any taxes required to be withheld under Federal, state or local law as a result of the: (i) grant of any
Award, (ii) exercise of any Option, (iii) sale of Shares issued upon exercise of Options, (iv) delivery of Shares, cash or other property, (v) lapse of restrictions in connection with any Award, or (vi) any other event
occurring pursuant to the Plan. To the extent that compensation and other amounts, if any, payable to the Participant (or Permitted Assignee) are insufficient to pay any taxes required to be so withheld, the Company may, in its sole discretion,
require the Participant (or Permitted Assignee), including without limitation, as a condition of the exercise of any Option, to pay in cash to the Company an amount sufficient to cover such tax liability or otherwise to make adequate provision for
the delivery to the Company of cash necessary to satisfy the Company’s withholding obligations under Federal and state law. The Committee shall be authorized to establish procedures for election by Participants (or Permitted Assignees) to
satisfy such obligations for the payment of such taxes by tendering previously acquired Shares (either actually or by attestation, valued at their then Fair Market Value) that have been owned for a period of at least six months (or such other period
as may be necessary to avoid accounting charges against the Company’s earnings), or by directing the Company to retain Shares (up to the Participant’s (or Permitted Assignee’s) minimum required tax withholding rate) otherwise
deliverable in connection with the Award. 
 b. Other Plans. Nothing contained in the Plan shall prohibit the Company
from establishing additional incentive compensation arrangements. 
 c. No Enlargement of Rights. Neither the Plan, nor
the granting of Awards, nor any other action taken pursuant to the Plan shall constitute or be evidence of any agreement or understanding, express or implied, that the Company will retain an Eligible Individual for any period of time, or at any
particular rate of compensation. Nothing in the Plan shall be deemed to limit or affect the right of the Company to discharge any Eligible Individual at any time for any reason or no reason. 

No Eligible Individual shall have any right to or interest in Awards authorized hereunder prior to the grant thereof to such eligible
person, and upon such grant he or she shall have only such rights and interests as are expressly provided herein and in the related Award Agreement, subject, however, to all applicable provisions of the Company’s Articles of Incorporation, as
the same may be amended from time to time. The Company shall not be liable for the loss of existing or potential profit from an Award in the event of termination of an employment or other relationship. 

d. Notice. Any notice to be given to the Company pursuant to the provisions of the Plan shall be addressed to the Company in care
of its Secretary (or such other person as the Company may designate from time to time) at its principal office, and any notice to be given to a Participant to whom an Award is granted hereunder shall be delivered personally or addressed to him or
her at the address given beneath his or her signature on his or her Award Agreement, or at such other address as such Participant or his or her transferee (upon any permitted transfer) may hereafter designate in writing to the Company. Any such
notice shall be deemed duly given when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, registered or certified, and deposited, postage and registry or certification fee prepaid, in a post office or branch post office
regularly maintained by the United States Postal Service. It shall be the obligation of each Participant holding Shares purchased upon exercise of an Option or otherwise issued pursuant to Awards hereunder to provide the Secretary of the Company, by
letter mailed as provided hereinabove, with written notice of his or her direct mailing address. 

  
 22 

 e. Applicable Law. To the extent that Federal laws do not otherwise control, the Plan
shall be governed by and construed in accordance with the laws of the State of California, without regard to the conflict of laws rules thereof. 
 f. Incentive Stock Options. The Company shall not be liable to a Participant or other person if it is determined for any reason by the Internal Revenue Service or any court having jurisdiction that
any Incentive Stock Options are not incentive stock options as defined in Section 422 of the Code. 
 g. Information to
Participants. The Company shall provide without charge to each Participant copies of its annual financial statements (which need not be audited), which may be included within such annual and periodic reports as are provided by the Company to its
shareholders generally. 
 h. Availability of Plan. A copy of the Plan shall be delivered to the Secretary of the Company
and shall be shown by him or her to any eligible person making reasonable inquiry concerning it. 
 i. Severability. In
the event that any provision of the Plan is found to be invalid or otherwise unenforceable under any applicable law, such provisions shall be deemed limited to the extent that a court of competent jurisdiction decrees it valid or enforceable and as
so limited shall remain in full force and effect. Any such provision shall not be construed as rendering any other provisions contained herein as invalid or unenforceable, and all such other provisions shall be given full force and effect to the
same extent as though the invalid or unenforceable provision was not contained herein. If the making of any payment or the provision of any other benefit required under the Plan shall be held unlawful or otherwise invalid or unenforceable by a court
of competent jurisdiction or any governmental regulatory agency, or impermissible under the rules of any stock exchange or quotation system on which the Shares are listed or quoted, such unlawfulness, invalidity, unenforceability or impermissibility
shall not prevent any other payment or benefit from being made or provided under the Plan, and if the making of any payment in full or the provision of any other benefit required under the Plan in full would be unlawful or otherwise invalid or
impermissible, then such unlawfulness, invalidity or impermissibility shall not prevent such payment or benefit from being made or provided in part, to the extent that it would not be unlawful, invalid or impermissible and the maximum payment or
benefit that would not be unlawful, invalid or impermissible shall be made or provided under the Plan. 
 j. Form of Shares
and Restricted Stock Awards; Stop Transfer Orders. Shares issued or delivered under the Plan, including Shares subject to any Restricted Stock Award, may be evidenced in such manner as the Committee in its sole discretion shall deem appropriate,
including, without limitation, book-entry registration or issuance of a stock certificate or certificates. In the event any stock certificate is issued in respect of a Restricted Stock Award, such certificate shall bear an appropriate legend
referring to the terms, conditions and restrictions applicable to such Award. All certificates for Shares delivered under the Plan pursuant to any Award shall be subject to such stop transfer orders and other restrictions as the Committee may deem
advisable under the rules, 

  
 23 

 
regulations and other requirements of the Securities and Exchange Commission, any stock exchange or quotation system upon which the Shares are then listed or quoted, and any applicable federal or
state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 
 k. Unfunded Status of the Plan. The Plan is intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant by the
Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company. In its sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet
the obligations created under the Plan to deliver the Shares or payments in lieu of or with respect to Awards hereunder; provided, however, that the existence of such trusts or other arrangements is consistent with the unfunded status
of the Plan. 
 l. Compliance with Code Section 409A/Taxes. It is intended that no Award granted under this Plan
shall be subject to any interest or additional tax under Section 409A of the Code. In the event Code Section 409A is amended after the date hereof, or regulations or other guidance is promulgated after the date hereof that would make an
Award under the Plan subject to the provisions of Code Section 409A, then the terms and conditions of this Plan shall be interpreted and applied, to the extent possible, in a manner to avoid the imposition of the provisions of Code
Section 409A. Notwithstanding the preceding, the Participant shall be responsible for any and all tax liabilities, including liability under 409A (but excluding the employer’s share of employment taxes) with respect to an Award.

 m. Performance Conditions. The Committee may require the satisfaction of certain performance goals as a condition to
the grant or vesting of any Award provided under the Plan. 
 n. Substitute Awards. Notwithstanding any other provision
of the Plan, the terms of awards described in Section 3(c) may vary from the terms set forth in the Plan to the extent the Committee deems appropriate to conform, in whole or in part, to the provisions of the awards in substitution for which
they are granted. 
 o. Cancellation of Award; Forfeiture of Gain. Notwithstanding anything to the contrary contained
herein, an Award Agreement may provide that: 
  

	 	(i)	In the event of an accounting restatement due to material noncompliance by the Company with any financial reporting requirement under the securities laws which reduces
the amount of the Award that would have been earned had the financial results been properly reported (as determined by the Committee), the following adjustments shall be made to the extent the amount of the Award was over-stated as a result of such
noncompliance (A) the Award will be cancelled and (B) the Participant will forfeit (I) the Shares received or payable on the vesting or exercise of the Award and (II) the amount of the proceeds of the sale or gain realized on the
vesting or exercise of the Award (and the Participant may be required to return or pay such Shares or amount to the Company). The provisions of this Section 19(o)(i) will continue to apply as may be amended to comply with final regulations
issued under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

	 	(ii)	If the Participant, without the consent of the Company, while employed by or providing services to the Company or any Affiliate or after termination of such employment
or service, violates a noncompetition, nonsolicitation or nondisclosure covenant or agreement or otherwise engages in activity that is in conflict with or adverse to the interest of the Company or any Affiliate, as determined by the Committee in its
sole discretion, then (A) any outstanding, vested or unvested, earned or unearned portion of the Award may, at the Committee’s discretion, be canceled and (B) the Committee, in its discretion, may require the Participant or other

recipients may be located in the Participant’s country, or elsewhere, and that the recipient’s country may have different data privacy laws and protections than the Participant’s country. The Participant understands that he or she may
request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. The Participant, through participation in the Plan and acceptance of an Award under the Plan,
authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing the Participant’s participation in the Plan, including any requisite
transfer of such Data as may be required to a broker or other third party with whom the Participant may elect to deposit any Shares. The Participant understands that the Data will be held only as long as is necessary to implement, manage, and
administer the Participant’s participation in the Plan. The Participant understands that he or she may, at any time, view the Data, request additional information about the storage and processing of the Data, require any necessary amendments to
the Data, or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources representative. The Participant understands that refusal or

  
 25 

 
withdrawal of consent may affect the Participant’s ability to participate in the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the
Participant understands that he or she may contact his or her local human resources representative. 
 20. Effective
Date and Term of Plan. 
 The original Plan became effective upon shareholder approval at the 2008 Annual Meeting of
Shareholders of the Company in accordance with the shareholder approval provisions of Section 16. The Amended and Restated Plan became effective upon shareholder approval at the 2010 Annual Meeting of Shareholders of the Company in accordance

	 	(b)	Cashless Exercise. Through a special sale and remittance procedure commonly referred to as a “cashless exercise” or “sell to cover”
transaction pursuant to which the Participant (or any other person(s) entitled to exercise the Option) shall concurrently provide irrevocable written instructions: 

 

	 	(i)	to such third party service provider as may be designated by the Company, including without limitation E*Trade (through your on-line account) or such other brokerage
firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment in Common Stock of the Company to effect the immediate sale of a sufficient number of the Shares purchased upon the exercise of the
Option to enable such third-party (e.g., E*Trade or other designated third party) to remit, out of the sales proceeds available upon the settlement date, sufficient funds to the Company to cover the aggregate exercise price payable for the purchased
Shares plus all applicable federal, state and local income and employment taxes required to be withheld by the Company by reason of such exercise and/or sale; and 

 

	 	(ii)	to the Company to deliver any certificate(s) or other evidence of ownership for the purchased Shares directly to such third party (e.g., E*Trade or other designated

	4.	Exercise of Option. This Option shall be exercisable during its term only in accordance with the terms and provisions of the Plan and this Option as follows:

  

	 	(a)	This Option shall vest and be exercisable cumulatively as set forth on the first page of the Stock Option Agreement. A Participant who has maintained his or her
Continuous Status as an Eligible Individual since the grant of this Option may exercise the exercisable portion of his or her Option in whole or in part at any time during his or her employment; provided, however, that an Option may
not be exercised for a fraction of a Share. In the event that a Participant terminates employment with the Company, is disabled or dies, the provisions of Sections 6 or 7 below shall apply to the right of the Participant to exercise the Option
except as otherwise provided in the Plan,. 

  

	 	(b)	This Option shall be exercisable by following such procedures as may from time to time be prescribed by the Company, E*Trade (in connection with the OptionsLink online

Company. 

  

	 	(c)	No rights of a shareholder shall exist with respect to the Shares under this Option as a result of the mere grant of this Option or the exercise of this Option. Such
rights shall exist only after issuance of a stock certificate or electronic transfer of the shares to the Participant’s brokerage account in accordance with the Plan. 

 

	5.	Restrictions on Exercise. This Option may not be exercised if the issuance of Shares upon Participant’s exercise or the method of payment of consideration
for such Shares would constitute a violation of any applicable Federal or state securities law or other applicable law or regulation. As a condition to the exercise of this Option, the Company may require the Participant to make any representation
and warranty to the Company as may be required by any applicable law or regulation. 

  

	6.	Termination of Employment. If the Participant ceases to serve as an Employee or Consultant for any reason other than death or permanent and total disability
(within the meaning of Section 22(e)(3) of the Code) or Termination for Cause and thereby terminates his or her Continuous Status as an Eligible Individual, the Participant shall have the right to exercise this Option at any time within 90 days
after the date of such termination to the extent that the Participant was entitled to exercise this Option at the date of such termination. To the extent that the Participant was not entitled to exercise this Option at the date of termination, or to
the extent this Option is not exercised within the time specified herein, this Option shall terminate. Notwithstanding the foregoing, this Option shall not be exercisable as to any vested installment after the expiration of its term as described in
Section 8 hereof. If the Participant ceases to serve as an Employee or Consultant due to his or her Termination for Cause and thereby terminates his or her Continuous Status as an Eligible Individual, the Participant shall immediately forfeit
the Option subject to this Agreement. This provision does not apply to an Award made to a Participant in his or her capacity as a Director. 

  
 29 

	7.	Death or Disability. If the Participant ceases to serve as an Employee or Consultant due to death or permanent and total disability (within the meaning of
Section 22(e)(3) of the Code), this Option may be exercised at any time within 180 days after the date of death or termination of employment or service due to disability, in the case of death, by the Participant’s estate or by a person who
acquired the right to exercise this Option by bequest or inheritance, or, in the case of disability, by the Participant, but in any case only to the extent the Participant was entitled to exercise this Option at the date of such termination. To the
extent that the Participant was not entitled to exercise this Option at the date of termination, or to the extent this Option is not exercised within the time specified herein, this Option shall terminate. Notwithstanding the foregoing, this Option
shall not be exercisable as to any vested installment after the expiration of its term as described in Section 8 hereof. This provision does not apply to an Award made to a Participant in his or her capacity as a Director.

  

	8.	Term of Option. This Option shall expire and terminate for all purposes at 5:00 p.m., Pacific Time, on the expiration date set forth on the first page of
the Stock Option Agreement. To the extent that this Option is not exercised prior to such time and date, this Option shall expire and terminate. This Option shall be subject to earlier termination as provided in Sections 6 and 7 above. This
Option may be exercised only in accordance with the Plan and these Terms and Conditions. Notwithstanding any provision in the Plan or in these Terms and Conditions with respect to the post-employment exercise of this Option, this Option may
not be exercised with respect to any Shares subject to any vested installment after expiration of the term of this Option. 

  

	9.	Withholding upon Exercise of Option. The Company reserves the right to withhold, in accordance with any applicable laws, from any consideration payable to
Participant any taxes required to be withheld by Federal, state or local law as a result of the grant or exercise of this Option or the sale or other disposition of the Shares issued upon exercise of this Option; provided, however, that such
withholding shall not exceed the minimum required tax withholding rate for the Participant or such other rate that will not cause an adverse accounting consequence or cost. If the amount of any consideration payable to the Participant is
insufficient to pay such taxes or if no consideration is payable to the Participant, upon the request of the Company, the Participant shall pay to the Company in cash an amount sufficient for the Company to satisfy any Federal, state or local tax
withholding requirements it may incur as a result of the grant or exercise of this Option or the sale or other disposition of the Shares issued upon the exercise of this Option. 

 

	10.	Nontransferability of Option. This Option may not be sold, pledged, assigned, hypothecated, gifted, transferred or disposed of in any manner either voluntarily
or involuntarily by operation of law, other than by will or by the laws of descent or distribution. Subject to the foregoing and the terms of the Plan, the terms of this Option shall be binding upon the executors, administrators, heirs, successors
and assigns of the Participant. 

  

	11.	No Right of Employment. Neither the Plan nor this Option shall confer upon the Participant any right to continue in the employment or service of the Company or
limit in any respect the right of the Company to discharge the Participant at any time, with or without cause and with or without notice. 

  
 30 

	12.	Miscellaneous. 

  

	 	(a)	Successors and Assigns. This Option Agreement shall bind and inure only to the benefit of the parties to this Option Agreement (the “Parties”) and
their respective successors and assigns. 

  

	 	(b)	No Third-Party Beneficiaries. Nothing in this Option Agreement is intended to confer any rights or remedies on any persons other than the Parties and their
respective successors or assigns. Nothing in this Option Agreement is intended to relieve or discharge the obligation or liability of third persons to either Party. No provision of this Option Agreement shall give any third person any right of
subrogation or action over or against either Party. 

  

	 	(c)	Amendments. 

  

	 	(i)	The Committee reserves the right to amend the terms and provisions of this Option without the Participant’s consent to comply with any Federal or state securities
law. 

  

	 	(ii)	Except as specifically provided in subsection 12(c)(i) above, this Option Agreement and these Terms and Conditions shall not be changed or modified, in whole or in
part, except by supplemental agreement signed by the Parties. Either Party may waive compliance by the other Party with any of the covenants or conditions of this Option Agreement, but no waiver shall be binding unless executed in writing by the
Party making the waiver. No waiver or any provision of this Option Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver. Any consent under this
Option Agreement shall be in writing and shall be effective only to the extent specifically set forth in such writing. 

  

	 	(d)	Governing Law. To the extent that Federal laws do not otherwise control, the Plan and all determinations made or actions taken pursuant hereto shall be governed
by the laws of the State of California, without regard to the conflict of laws rules thereof. 

  

	 	(e)	Severability. If any provision of this Option Agreement or the application of such provision to any person or circumstances is held invalid or unenforceable, the
remainder of this Option Agreement, or the application of such provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby.

 SECOND AMENDED AND RESTATED IXIA 2008 EQUITY INCENTIVE PLAN 

Restricted Stock Award Agreement—Terms and Conditions 
 The following Terms and Conditions apply to the Restricted Stock granted by Ixia (“Company”) to the Participant whose name appears on the Restricted Stock Award Agreement to which these Terms
and Conditions are attached (the “Restricted Stock”). 
 1. Award Subject to Plan. This Award is made under and is expressly
subject to all the terms and provisions of the Second Amended and Restated Ixia 2008 Equity Incentive Plan (the “Plan”) adopted by the Company and incorporated herein by reference. The terms defined in the Plan shall have the same meanings
herein 
 2. Vesting of Restricted Stock. 
  

	 	(a)	 [e.g., Upon each vesting date for the Restricted Stock Award (each, a “Vesting Date”), one share of Common Stock shall be deliverable for
each Restricted Stock that vests on such date, subject to the terms and provisions of the Plan and this Restricted Stock Award Agreement.][e.g., Following the end of the Performance Period, provided you remain employed by the Company during such
period and the Performance Goals are achieved at the end of the Performance Period, one share of Common Stock shall be deliverable for each Restricted Stock, subject to the terms and provisions of the Plan and this Restricted Stock Award Agreement.]
Following vesting, the Company will deliver such Shares to the Participant as soon as administratively feasible and following satisfaction of any required withholding tax obligations as provided in Section 4 below. Notwithstanding anything to
the contrary set forth herein, delivery of Shares pursuant to a Restricted Stock Award shall be made no later than 2  1/2 months after the close of Company’s first taxable year in which such Shares are no longer subject to a
substantial risk of forfeiture (within the meaning of Section 409A of the Code). 

  

	 	(b)	To the extent the Restricted Stock vests and Shares are delivered to the Participant, such Shares will be free of the terms and conditions of this Restricted Stock
Award Agreement. 

  

	 	(c)	All rights of a shareholder shall exist with respect to the Restricted Stock as a result of the grant of the Restricted Stock. Such rights shall exist beginning on the
date of grant of the Restricted Stock Award and subject to execution of this Restricted Stock Award Agreement; however, any Shares or any other property (other than cash) distributed as a dividend or otherwise with respect to any such Shares as to
which the restrictions have not yet lapsed shall be subject to the same restrictions as the Shares subject to the Restricted Stock Award. 

 3. Delivery of Shares. The Shares of Restricted Stock described herein shall be granted in the form of Shares registered in the name of the Participant but held by the Company until the
restrictions on the award lapse, subject to forfeiture as provided herein. 
 4. Taxes. The Participant is responsible for any federal,
state, local or other income, employment or other applicable taxes required to be withheld under Federal, state, local or other law in connection with: (i) the vesting of the Restricted Stock Award and the issuance and delivery of Shares to the
Participant, or (iii) any other event occurring pursuant to this Restricted Stock Award Agreement or the Plan (collectively, “Taxes”). The Participant acknowledges that in connection with the issuance of Shares upon the vesting of
Restricted Stock, the Company is required to withhold from the Participant an amount that is sufficient to satisfy the Company’s Tax withholding obligations. 

  
 34 

 
Notwithstanding any contrary provision of this Restricted Stock Award Agreement or the Plan, no Shares will be issued to the Participant (or his or her estate, if applicable) upon vesting of
Restricted Stock unless and until satisfactory arrangements (as determined by the Committee) have been made by the Participant with respect to the withholding and payment of Taxes which the Company determines must be withheld with respect to such
Shares. Notwithstanding any contrary provision of this Restricted Stock Award Agreement or the Plan, no Shares will be issued to the participant upon vesting of any Restricted Stock following the fifteenth day of the third month of the calendar year
following the calendar year in which such Restricted Stock vests. The Committee, in its sole discretion and pursuant to such procedures as it may specify from time to time, may (but is not required to) permit the Participant to satisfy such Tax
withholding obligations in any of the following ways: 
  

	 	(a)	Payment in Cash. The Participant may elect to pay to the Company an amount sufficient to cover such Taxes by delivering to the Company a check or by making a
cash deposit in the Participant’s brokerage account with E*Trade Securities LLC (“E*Trade”) or such other brokerage firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment
in Common Stock of the Company. 

  

	 	(b)	Cashless Exercise. Through a special sale and remittance procedure commonly referred to as a “cashless exercise” or “sell to cover”
transaction pursuant to which the Participant (or any other person(s) entitled to receive such Shares upon vesting) shall concurrently provide irrevocable written instructions: 

 

	 	(i)	to such third party service provider as may be designated by Company, including without limitation E*Trade (through your on-line account) or such other brokerage firm
as may be designated by the Company in connection with any Company plan or arrangement providing for investment in Common Stock of the Company to effect the immediate sale of a sufficient number of the Shares delivered upon the vesting of the Shares
to enable such brokerage firm to remit, out of the sales proceeds available upon the settlement date, sufficient funds to the Company to cover the aggregate exercise price payable for the purchased Shares plus all applicable federal, state and local
income and employment taxes required to be withheld by the Company by reason of such exercise and/or sale; and 

  

	 	(ii)	to the Company to deliver any certificate(s) or other evidence of ownership for such sold Shares directly to such third party (e.g., E*Trade or other designated third
party) in order to complete the sales transaction. 

  

	 	(c)	Payment by Withholding of Shares. In the Company’s sole discretion and in lieu of the Participant’s election under Section 4(b), the Company may
elect to retain that number of whole Shares which would otherwise be deliverable in connection with the Restricted Stock Award upon vesting and which have a Fair Market Value sufficient to satisfy the amount of the Taxes required to be withheld;
provided, however, that the number of Shares retained by the Company shall not exceed the minimum number required based on the tax withholding rate for the Participant or such other rate that will not cause an adverse accounting consequence or cost.
“Fair Market Value” for this purpose shall be as determined in the Plan as of the applicable date. 

  
 35 

	 	(d)	Company Rights. Any elections permitted to be made pursuant to this Section 4 shall be made in writing or via electronic transmission on such form as shall
be prescribed by the Company for such purpose. The Company also reserves the right to withhold Taxes, in accordance with any applicable law, from any compensation or other amounts payable to the Participant and/or, in accordance with
Section 4(c), from the Shares otherwise deliverable to the Participant upon the vesting of the Restricted Stock. 

 5.
Termination of Employment. [e.g., If the Participant ceases to serve as an Employee, Consultant or Director, as applicable, for any reason prior to the time restrictions on the Shares of Restricted Stock awarded pursuant to this Restricted
Stock Award Agreement lapse and thereby terminates his or her Continuous Status as an Eligible Individual, the Participant shall forfeit any Shares of Restricted Stock which are still subject to the restrictions at the time of termination of such
employment.][e.g., If the Participant ceases to serve as an Employee, Consultant or Director, as applicable, for any reason prior to the end of the Performance Period and thereby terminates his or her Continuous Status as an Eligible Individual, the
Participant shall forfeit any Shares of Restricted Stock which are still subject to the restrictions at the time of termination of such employment.] 
 6. Nontransferability. The Shares awarded pursuant to this Restricted Stock Award are nontransferable by the Participant until vested as set forth on the first page of this Restricted Stock
Award Agreement. Prior to the time such Shares become transferable, the Shares of Restricted Stock shall bear a legend indicating their nontransferability. 
 7. No Right of Employment. Neither the Plan nor this Restricted Stock Award shall confer upon the Participant any right to continue in the employment or service of the Company or limit in any
respect the right of the Company to discharge the Participant at any time, with or without cause and with or without notice. 
 8.
Amendments. 
  

	 	(a)	The Committee reserves the right to amend the terms and provisions of this Restricted Stock Award without the Participant’s consent to comply with any Federal or
state securities law. 

  

	 	(b)	Except as specifically provided in subsection (i) above, this Restricted Stock Award Agreement shall not be changed or modified, in whole or in part, except by
supplemental agreement signed by the Parties. Either Party may waive compliance by the other Party with any of the covenants or conditions of this Restricted Stock Award Agreement, but no waiver shall be binding unless executed in writing by the
Party making the waiver. No waiver or any provision of this Restricted Stock Award Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver. Any
consent under this Restricted Stock Award Agreement shall be in writing and shall be effective only to the extent specifically set forth in such writing. 

 9. Miscellaneous. 
  

	 	(a)	Successors and Assigns. This Restricted Stock Award Agreement shall bind and inure only to the benefit of the parties to this Restricted Stock Award Agreement
(the “Parties”) and their respective permitted successors and assigns. 

  
 36 

	 	(b)	No Third-Party Beneficiaries. Nothing in this Restricted Stock Award Agreement is intended to confer any rights or remedies on any persons other than the Parties
and their respective permitted successors or assigns. Nothing in this Restricted Stock Award Agreement is intended to relieve or discharge the obligation or liability of third persons to any Party. No provision of this Restricted Stock Award
Agreement shall give any third person any right of subrogation or action over or against any Party. 

  

	 	(c)	Governing Law. To the extent that Federal laws do not otherwise control, the Plan and all determinations made or actions taken pursuant hereto shall be governed
by the laws of the state of California, without regard to the conflict of laws rules thereof. 

 10. Severability. If any
provision of this Restricted Stock Award Agreement or the application of such provision to any person or circumstances is held invalid or unenforceable, the remainder of this Restricted Stock Award Agreement, or the application of such provision to
persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby.

 SECOND AMENDED AND RESTATED IXIA 2008 EQUITY INCENTIVE PLAN 

Restricted Stock Unit Award Agreement—Restricted Stock Unit Terms and Conditions 

The following Restricted Stock Unit Terms and Conditions apply to the Restricted Stock Unit Award granted by Ixia (“Company”) to the
Participant whose name appears on the Restricted Stock Unit Award Agreement cover page to which these Restricted Stock Unit Terms and Conditions are attached. 
  

	1.	Second Amended and Restated Ixia 2008 Equity Incentive Plan. This Restricted Stock Unit Award is in all respects subject to the terms, definitions and provisions
of the Second Amended and Restated Ixia 2008 Equity Incentive Plan (the “Plan”) adopted by Ixia and incorporated herein by reference. Capitalized terms defined in the Plan but not defined in this Restricted Stock Unit Award
Agreement shall have the meanings given to them in the Plan. 

  

	2.	Vesting of Restricted Stock Units Awards. 

  

	 	(a)	 [e.g., Upon each vesting date for the Restricted Stock Unit Award (each, a “Vesting Date”), one share of Company Common Stock shall be
issuable for each Restricted Stock Unit that vests on such date, subject to the terms and provision of the Plan and this Restricted Stock Unit Award Agreement.] [e.g., Following the end of the Performance Period, provided you remain employed by the
Company during such period and the Performance Goals are achieved at the end of the Performance Period, one share of Company Common Stock shall be issuable for each Restricted Stock Unit, subject to the terms and provisions of the Plan and this
Restricted Stock Unit Award Agreement.] Following vesting, the Company will issue and transfer such Shares to the Participant as soon as administratively feasible and following satisfaction of any required withholding tax obligations as provided in
Section 4 below. Notwithstanding anything to the contrary set forth herein, delivery of Shares pursuant to a Restricted Stock Unit Award shall be made no later than 2  1/2 months after the close of the Company’s first taxable year in which such Shares are no longer subject to a substantial risk of forfeiture (within the meaning of Section 409A of the Code).

  

	 	(b)	To the extent the Restricted Stock Units vest and Shares are issued and delivered to the Participant, such Shares will be free of the terms and conditions of this
Restricted Stock Unit Award Agreement. 

  

	 	(c)	No rights of a shareholder shall exist with respect to the Restricted Stock Units as a result of the mere grant of the Restricted Stock Units. Such rights shall exist
only after issuance of the Shares following the applicable Vesting Date. 

  

	3.	 Delivery of Shares upon Vesting of Restricted Stock Units. Restricted Stock Units (if not previously forfeited) will automatically be settled
[e.g., on or about the Vesting Date or Vesting Dates set forth on the cover page of this Restricted Stock Unit Award Agreement][e.g., following the end of the Performance Period set forth on the cover page of this Restricted Unit Award Agreement,
provided that the Performance Goals are achieved at the end of the Performance Period and the Participant remains employed with the Company through such date]. The Company may make delivery of Shares upon vesting of Restricted Stock Units either by
(i) delivering one or more stock certificates representing such Shares to the Participant, registered in the name of the Participant, or (ii) electronically depositing such Shares into an online securities account maintained for the
Participant as an Employee, 

  
 40 

	 	
Consultant or Director, as applicable, of the Company with E*Trade Securities LLC (“E*Trade”) or such other brokerage firm as may be designated by the Company in connection with any
Company plan or arrangement providing for investment in Common Stock of the Company. All certificates for Shares and all Shares shall be subject to such stop transfer orders and other restrictions as the Company may deem advisable under the rules,
regulations and other requirements of the Securities and Exchange Commission, any stock exchange or quotation system upon which the Shares are then listed or quoted, and any applicable Federal or state securities law, and the Company may cause a
legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

  

	4.	Taxes. The Participant is responsible for any federal, state, local or other income, employment or other applicable taxes required to be withheld under Federal,
state, local or other law in connection with: (i) the vesting of the Restricted Stock Unit Award and the issuance and delivery of Shares to the Participant, or (iii) any other event occurring pursuant to this Restricted Stock Unit Award
Agreement or the Plan (collectively, “Taxes”). The Participant acknowledges that in connection with the issuance of Shares upon the vesting of Restricted Stock Units, the Company is required to withhold from the Participant an
amount that is sufficient to satisfy the Company’s Tax withholding obligations. Notwithstanding any contrary provision of this Restricted Stock Unit Award Agreement or the Plan, no Shares will be issued to the Participant (or his or her estate,
if applicable) upon vesting of Restricted Stock Units unless and until satisfactory arrangements (as determined by the Committee) have been made by the Participant with respect to the withholding and payment of Taxes which the Company determines
must be withheld with respect to such Shares. Notwithstanding any contrary provision of this Restricted Stock Unit Award Agreement or the Plan, no Shares will be issued to the participant upon vesting of any Restricted Stock Unit following the
fifteenth day of the third month of the calendar year following the calendar year in which such Restricted Stock Unit vests. The Committee, in its sole discretion and pursuant to such procedures as it may specify from time to time, may (but is not
required to) permit the Participant to satisfy such Tax withholding obligations in any of the following ways: 

  

	 	(a)	Payment in Cash. The Participant may elect to pay to the Company an amount sufficient to cover such Taxes by delivering to the Company a check or by making a
cash deposit in the Participant’s brokerage account with E*Trade Securities LLC (“E*Trade”) or such other brokerage firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment
in Common Stock of the Company. 

  

	 	(b)	Cashless Exercise. Through a special sale and remittance procedure commonly referred to as a “cashless exercise” or “sell to cover”
transaction pursuant to which the Participant (or any other person(s) entitled to receive the Shares upon vesting) shall concurrently provide irrevocable written instructions: 

 

	 	(i)	to such third party service provider as may be designated by the Company, including without limitation E*Trade (through the Participant’s on-line account) or such
other brokerage firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment in Common Stock of the Company to effect the immediate sale of a sufficient number of the Shares acquired upon the
vesting of the Shares to enable such brokerage firm to remit, out of the sales proceeds available upon the settlement date, sufficient funds to the Company to cover all applicable federal, state and local income and employment taxes required to be
withheld by the Company by reason of such exercise and/or sale; and 

  
 41 

	 	(ii)	to the Company to deliver any certificate(s) or other evidence of ownership for such sold Shares directly to such third party (e.g., E*Trade or other designated third
party) in order to complete the sales transaction. 

  

	 	(c)	Payment by Withholding of Shares. In the Company’s sole discretion and in lieu of the Participant’s election under Section 4(b), the Company may
elect to retain that number of whole Shares which would otherwise be deliverable in connection with the Restricted Stock Unit Award upon vesting and which have a Fair Market Value sufficient to satisfy the amount of the Taxes required to be
withheld; provided, however, that the number of Shares retained by the Company shall not exceed the minimum number required based on the tax withholding rate for the Participant or such other rate that will not cause an adverse accounting
consequence or cost. “Fair Market Value” for this purpose shall be as determined in the Plan as of the applicable Vesting Date. 

  

	 	(d)	Company Rights. Any elections permitted to be made pursuant to this Section 4 shall be made in writing or via electronic transmission on such form as shall
be prescribed by the Company for such purpose. The Company also reserves the right to withhold Taxes, in accordance with any applicable law, from any compensation or other amounts payable to the Participant and/or (ii) in accordance with
Section 4(c), the Shares otherwise issuable to the Participant. 

  

	5.	Termination of Employment. [e.g., If the Participant ceases to serve as an Employee, Consultant or Director, as applicable, for any reason and thereby terminates
his or her Continuous Status as an Eligible Individual, the Participant’s Restricted Stock Units which are not vested as of the date of such termination shall not vest and shall automatically be cancelled and forfeited for no value and without
any issuance of Shares.][e.g., If the Participant ceases to serve as an Employee, Consultant or Director, as applicable, for any reason and thereby terminates his or her Continuous Status as an Eligible Individual prior to the end of the Performance
Period, the Participant’s Restricted Stock Units shall not vest and shall automatically be cancelled and forfeited for no value and without any issuance of Shares.] 

 

	6.	Nontransferability of Restricted Stock Units. This Restricted Stock Unit Award may not be sold, pledged, assigned, hypothecated, gifted, transferred or disposed
of in any manner either voluntarily or involuntarily by operation of law, other than transfers between spouses incident to a divorce. Subject to the foregoing and the terms of the Plan, the terms of this Restricted Stock Unit Award shall be binding
upon the executors, administrators, heirs, successors and assigns of the Participant. The Shares issued upon vesting of the Restricted Stock Unit Award will not be subject to restrictions on transfer under this Section 6.

  

	7.	No Dividend Equivalents. The Participant shall not be entitled to receive, currently or on a deferred basis, any payments (i.e., “dividend
equivalents”) equivalent to cash, stock or other property paid by the Company as dividends on the Company’s Common Stock prior to the vesting of the Restricted Stock Units. 

 

	8.	No Right of Employment. Neither the Plan nor this Restricted Stock Unit Award shall confer upon the Participant any right to continue in the employment or
service of the Company or limit in any respect the right of the Company to discharge the Participant at any time, with or without cause and with or without notice. 

  
 42 

	9.	Restrictions on Issuance. Shares shall not be issued with respect to this Restricted Stock Unit Award if the issuance of Shares would constitute a violation of
any applicable Federal or state securities law or other applicable law or regulation. As a condition to the issuance of Shares pursuant to this Restricted Stock Unit Award, the Company may require the Participant to make any representation and
warranty to the Company as may be required by any applicable law or regulation. 

  

	10.	Miscellaneous. 

  

	 	(a)	Successors and Assigns. This Restricted Stock Unit Award Agreement shall bind and inure only to the benefit of the parties to this Restricted Stock Unit Award
Agreement (the “Parties”) and their respective permitted successors and assigns. 

  

	 	(b)	No Third-Party Beneficiaries. Nothing in this Restricted Stock Unit Award Agreement is intended to confer any rights or remedies on any persons other than the
Parties and their respective permitted successors or assigns. Nothing in this Restricted Stock Unit Award Agreement is intended to relieve or discharge the obligation or liability of third persons to any Party. No provision of this Restricted Stock
Unit Award Agreement shall give any third person any right of subrogation or action over or against any Party. 

  

	 	(c)	Amendments. 

  

	 	(i)	The Committee reserves the right to amend the terms and provisions of this Restricted Stock Unit Award without the Participant’s consent to comply with any Federal
or state securities law. 

  

	 	(ii)	Except as specifically provided in subsection (i) above, this Restricted Stock Unit Award Agreement shall not be changed or modified, in whole or in part, except
by supplemental agreement signed by the Parties. Either Party may waive compliance by the other Party with any of the covenants or conditions of this Restricted Stock Unit Award Agreement, but no waiver shall be binding unless executed in writing by
the Party making the waiver. No waiver or any provision of this Restricted Stock Unit Award Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver.
Any consent under this Restricted Stock Unit Award Agreement shall be in writing and shall be effective only to the extent specifically set forth in such writing. 

 

	 	(d)	Governing Law. To the extent that Federal laws do not otherwise control, the Plan and all determinations made or actions taken pursuant hereto shall be governed
by the laws of the state of California, without regard to the conflict of laws rules thereof. 

  

	 	(e)	Severability. If any provision of this Restricted Stock Unit Award Agreement or the application of such provision to any person or circumstances is held invalid
or unenforceable, the remainder of this Restricted Stock Unit Award Agreement, or the application of such provision to persons or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby.

 Second Amended and Restated Ixia 2008 Equity Incentive Plan 

SAR Award Agreement – Terms and Conditions 
 The following Terms and Conditions apply to the SARs granted by Ixia (“Company”) to the Participant whose name appears on the SAR Award Agreement to which these Terms and Conditions are attached
(the “SARs”). 
  

	1.	Second Amended and Restated Ixia 2008 Equity Incentive Plan. The SARs are in all respects subject to the terms, definitions and provisions of the Second Amended
and Restated Ixia 2008 Equity Incentive Plan (the “Plan”) adopted by Ixia and incorporated herein by reference. The terms defined in the Plan shall have the same meanings herein. 

 

	2.	Payment of SAR Amount. The SARS shall be payable in shares of the Company’s Common Stock and, upon exercise of the SARs, in whole or in part, the
Participant shall be entitled to receive from the Company such number of Shares as is determined by multiplying (x) the excess of the Fair Market Value of a Share on the date of exercise over the Grant Price times (y) the number of Shares
with respect to which the SAR Award is exercised, and dividing such product by (z) the Fair Market Value of a Share on the date of exercise. The resulting number (rounded down to the nearest whole number) shall be the number of Shares to be
issued to the Participant upon the exercise of the SARs. The Participant shall not be entitled to receive any fractional Share or cash for any fractional Share as a result of any such rounding down upon exercise of the SARs.

  

	3.	Exercise of SARs. The SARs shall be exercisable during their term only in accordance with the terms and provisions of the Plan and these Terms and Conditions as
follows: 

  

	 	(a)	Vesting. The SARs shall vest and be exercisable cumulatively as set forth on the first page of this SAR Award Agreement. Provided the Participant has maintained
his or her Continuous Status as an Eligible Individual since the grant of these SARs, the Participant may exercise the exercisable (i.e., vested) portion of his or her SARs in whole or in part at any time during his or her employment;
provided, however, that the SARs may not be exercised for a fraction of a Share. In the event of the Participant’s termination of employment or service with the Company or the Participant’s disability or death, the provisions
of Sections 7 or 8 below shall apply to the right of the Participant to exercise the SARs. 

  

	 	(b)	Manner of Exercise. The SARs shall be exercisable by following such procedures as may from time to time be prescribed by the Company or by any third party
service provider designated by the Company, including without limitation, E*Trade Securities LLC (“E*Trade”) in connection with the OptionsLink online securities account maintained by the Participant with E*Trade as an Employee, Consultant
or Director, as applicable, of the Company or such other brokerage firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment in Common Stock of the Company. 

 

	 	(c)	No Shareholder Rights. No rights of a shareholder shall exist with respect to the Shares under the SARs as a result of the mere grant of the SARs or the exercise
of the SARs. Such rights shall exist only after issuance of a stock certificate or electronic transfer of the Shares to the Participant’s brokerage account in accordance with the Plan. 

  
 45 

	 	(d)	Tandem SARs. Any of the SARs which are Tandem SARs may be exercised by the Participant for all or part of the Shares subject to the related Option upon the
surrender of the right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable. 

 

	4.	Delivery of Shares upon Exercise of SARs. The Company may make delivery of Shares upon exercise of the SARs either by (i) delivering one or more stock
certificates representing such Shares to the Participant, registered in the name of the Participant, or (ii) depositing such Shares into an account maintained for the Participant and established in connection with any Company plan or
arrangement providing for investment in Common Stock of the Company, including without limitation any on-line securities account maintained by the Participant with E*Trade in connection with is or her employment or service with the Company. All
certificates for Shares and all Shares shall be subject to such stop transfer orders and other restrictions as the Company may deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any stock
exchange or quotation system upon which the Shares are then listed or quoted, and any applicable Federal or state securities law, and the Company may cause a legend or legends to be put on any such certificates (or other appropriate restrictions
and/or notations to be associated with any accounts in which such Shares are held) to make appropriate reference to such restrictions. 

  

	5.	Taxes. The Participant is responsible for any taxes required to be withheld under Federal, state or local law in connection with: (i) the exercise of the
SARs and the issuance and delivery of Shares to the Participant, or (ii) any other event occurring pursuant to this SAR Award Agreement or the Plan (collectively, “Taxes”). Any election pursuant to this Section 5 shall be made in
writing on such form or electronically in such manner shall be prescribed by the Company for such purpose. 

  

	 	(a)	Payment in Cash. The Participant may elect to pay to the Company an amount sufficient to cover such Taxes by delivering to the Company a check or by such other
means as the Company may establish or permit. 

  

	 	(b)	Cashless Exercise. The Participant may elect to pay the Company his or her obligations for the payment of such Taxes through a special sale and remittance
procedure commonly referred to as a “cashless exercise” or “sell to cover” transaction pursuant to which the Participant (or any other person(s) entitled to exercise the SARs) shall concurrently provide irrevocable written
instructions: 

  

	 	(i)	to such third party service provider as may be designated by the Company, including without limitation E*Trade (through the Participant’s on-line account) or such
other brokerage firm as may be designated by the Company in connection with any Company plan or arrangement providing for investment in Common Stock of the Company to effect the immediate sale of a sufficient number of the Shares acquired upon the
exercise of the SARs to enable such third party (e.g., E*Trade or other designated third party) to remit, out of the sales proceeds available upon the settlement date, sufficient funds to the Company to cover all applicable federal, state and local
income and employment taxes required to be withheld by the Company by reason of such exercise and/or sale; and 

  
 46 

	 	(ii)	to the Company to deliver any certificate(s) or other evidence of ownership for such sold Shares directly to such third party (e.g., E*Trade or other designated third
party) in order to complete the sales transaction. 

  

	 	(c)	[If Applicable] [Payment by Withholding of Shares. Subject to approval by Company management and compliance with any applicable legal conditions or restrictions,
the Participant may also elect to satisfy his or her obligations for the payment of such Taxes by having the Company retain that number of whole Shares which would otherwise be deliverable in connection with the exercise of the SARs and which have a
Fair Market Value sufficient to satisfy the amount of the Taxes required to be withheld; provided, however, that the number of Shares retained by the Company shall not exceed the minimum number required based on the tax withholding rate for the
Participant or such other rate that will not cause an adverse accounting consequence or cost. “Fair Market Value” for this purpose shall be as determined in the Plan as of the applicable exercise date.] 

 

	 	(d)	Company Rights. The Company also reserves the right, and the Participant authorizes the Company, to withhold Taxes, in accordance with any applicable law, from
(i) any compensation or other amounts payable to the Participant and/or (ii) in accordance with Section 4(c), the Shares otherwise issuable to the Participant upon exercise of the SARs. 

 

	6.	Restrictions on Exercise. The SARs may not be exercised if the issuance of Shares upon Participant’s exercise or the method of payment of consideration for
such Shares would constitute a violation of any applicable Federal or state securities law or other applicable law or regulation. As a condition to the exercise of the SARs, the Company may require the Participant to make any representation and
warranty to the Company as may be required by any applicable law or regulation. 

  

	7.	Termination of Employment. If the Participant ceases to serve as an Employee or Consultant for any reason other than death or permanent and total disability
(within the meaning of Section 22(e)(3) of the Code) and thereby terminates his or her Continuous Status as an Eligible Individual, the Participant shall have the right to exercise the SARs at any time within 90 days after the date of such
termination to the extent that the Participant was entitled to exercise the SARs at the date of such termination. To the extent that the Participant was not entitled to exercise the SARs at the date of termination, or to the extent the SARs are not
exercised within the time specified herein, the SARs shall terminate. Notwithstanding the foregoing, the SARs shall not be exercisable after the expiration of the term set forth in Section 9 hereof. This provision does not apply to an Award
made to a Participant in his or her capacity as a Director. 

  

	8.	 Death or Disability. If the Participant ceases to serve as an Employee or Consultant due to death or permanent and total disability (within the
meaning of Section 22(e)(3) of the Code), the SARs may be exercised at any time within 180 days after the date of death or termination of employment due to disability, in the case of death, by the Participant’s estate

  
 47 

	 	
or by a person who acquired the right to exercise the SARs by bequest or inheritance, or, in the case of disability, by the Participant, but in any case only to the extent the Participant was
entitled to exercise the SARs at the date of such termination. To the extent that the Participant was not entitled to exercise the SARs at the date of termination, or to the extent the SARs are not exercised within the time specified herein, the
SARs shall terminate. Notwithstanding the foregoing, the SARs shall not be exercisable after the expiration of the term set forth in Section 9 hereof. This provision does not apply to an Award made to a Participant in his or her capacity as a
Director. 

  

	9.	Term of SARs. The SARs shall expire and terminate for all purposes on [_________, 20__], and may be exercised during such term only in accordance with the Plan
and the terms of this SAR Award Agreement. To the extent that the SARs are not exercised prior to such time and date, the SARs shall expire and terminate. Such exercise period shall be subject to earlier termination as provided in Sections 7
and 8 above. Notwithstanding any provision in the Plan with respect to the post-employment exercise of the SARs, the SARs may not be exercised after the expiration of the term of the SARs. 

 

	10.	Nontransferability of SARs. No SAR may be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of
descent and distribution or transfer between spouses incident to a divorce. Subject to the foregoing and the terms of the Plan, the terms of this SAR Award Agreement shall be binding upon the executors, administrators, heirs, successors and assigns
of the Participant. 

  

	11.	No Right of Employment. Neither the Plan nor the SARs shall confer upon the Participant any right to continue in the employment or service of the Company or
limit in any respect the right of the Company to discharge the Participant at any time, with or without cause and with or without notice. 

  

	12.	Miscellaneous.
