on the one hand, nor the Sellers, on the other hand, shall seek to recover any amounts from the other in respect of Section 5.28(c) of the Asset Sale Agreement if the severance costs actually incurred by the Sellers in connection with the
termination of employment by the Sellers of the Employees are, respectively, less than or greater than the amounts paid by the Purchaser at Closing pursuant to clauses (iv) and (v) of Section 2.3.2(a) of the Asset Sale Agreement.

 SECTION 5 Certain Specified UK Patents. The Parties hereby agree that, pursuant to Section 5.23 of the Asset Sale
Agreement, those Specified UK Patents set forth on Exhibit IV {Redacted Exhibit IV containing list of patents} attached hereto (the “Excluded Specified UK Patents”) shall be excluded from the Assets and shall not be
transferred to the Purchaser at the Closing; provided, however, that from and after the Closing Date and for a period of twelve (12) months thereafter (or such longer period as the Purchaser and the Primary Seller Parties agree in writing) (the
“Excluded Specified UK Patents’ Period”), the Sellers hereby covenant to cooperate with the Purchaser in contacting the relevant U.K. and U.S. Government agencies (including by means of engaging counsel at the Purchaser’s
expense), for the purpose of (to the extent permissible under applicable Law), modifying or removing, any security or disclosure restriction affecting the Excluded Specified UK Patents. During the Excluded Specified UK Patents’ Period, the
Purchaser shall pay all related fees, costs and expenses of outside counsel retained in respect of the Excluded Specified UK Patents (including for the avoidance of doubt any fees, costs and expenses incurred in providing secure storage for the
Excluded Specified UK Patents necessary to comply with applicable Law). If at any time from and after the Closing Date and for a period of twelve (12) months thereafter (or such longer period as the Purchaser and the Primary Seller Parties
agree in writing) the Purchaser notifies the Primary Seller Parties in writing that it or one or more of its limited partners as of the date hereof wishes to acquire any Excluded Specified UK Patents, the relevant Sellers shall, as soon as
practicable, execute an agreement, on terms the Purchaser, or as the case may be one or more of its limited partners as of the date hereof, shall reasonably deem necessary or appropriate to assign and transfer, to the extent permitted by applicable
Law, to the Purchaser or such limited partners, all of the Sellers’ right, title and interest in and to such Excluded Specified UK Patents and any Patent Related Documentation related thereto (including for the avoidance of doubt all documents
related to such Excluded Specified UK Patents currently held in secure storage) (the “Purchased Documentation”) to the Purchaser or such limited partners for nil consideration and in respect of which assignment agreement each Party will
bear its own costs. The Purchaser or such limited partner agrees to take permanent possession of all Purchased Documentation as soon as practicable after they are assigned. 
 SECTION 6 Miscellaneous Provisions. Sections 10.2 through 10.7, Section 10.9 through 10.11, Section 10.13 through Section 10.15, and Sections 10.18 through 10.23 of the Asset Sale
Agreement are hereby incorporated by reference and shall apply mutatis mutandis to this Amendment.

 Exhibit I 
 Amendments to Section 5.27(b)(ii)(C) 
 (C) (x) the Purchaser will
pay, or cause to be paid, the Optioned License Fees to the Sellers, Joint Administrators and the French Liquidator free and clear of and without deduction or withholding for withholding
Taxes or any other amounts; provided that if the Purchaser or, if relevant, any of the Purchaser’s limited partners shall be required under applicable Law to deduct or withhold any
amount from the Optioned Licenses Fees, then (i) the amount payable shall be increased as necessary so that, after making all required deductions or withholdings (including deductions or withholdings applicable to additional amounts payable),
the Sellers, Joint Administrators and the French Liquidator receive an amount equal to the sum they would have received had no such deduction or withholding been made, (ii) the Purchaser shall make
or shall cause to be made such deduction or withholding, and (iii) the Purchaser shall pay or shall cause to be paid
to the relevant Tax Authority in accordance with applicable Law the full amount deducted or withheld; provided, further, that Purchaser shall have no obligation to pay additional amounts pursuant to clause (i) of the preceding proviso to
the extent that the withholding Taxes are attributable to a Seller’s failure to comply with the requirements of Section 5.27(b)(ii)(C)(y) unless such failure is due to the Purchaser’s failure to cooperate fully with any Seller for the
purposes of obtaining any exemption or reduction referred to in Section 5.27(b)(ii)(C)(y). The Purchaser shall promptly furnish the Sellers, Joint Administrators and the French Liquidator with such evidence as may be required by the applicable
Tax Authorities to establish that any such Tax has been paid, and shall indemnify and hold harmless the Sellers, Joint Administrators and French Liquidator on an after-Tax basis from any liability for penalties or interest due to the payor’s
failure to timely withhold and remit amounts in respect of Taxes to the applicable Tax Authority; 

 Exhibit II 
 Amendments to Section 6.1 
 SECTION 6.1 Transfer Taxes.

 (a) The Parties agree that the Purchase Price
isand any Optioned License Fees are exclusive of any Transfer Taxes. The Purchaser shall promptly pay or
cause to be paid directly to the appropriate Tax Authority all applicable Transfer Taxes that may be imposed upon or payable or collectible or incurred in connection with this Agreement or the transactions contemplated herein, or that may be
imposed upon or payable or collectible or incurred in connection with the execution of any other Transaction Document; provided, that if any such Transfer Taxes are required to be collected, remitted or paid by a Seller, the Joint
Administrators, or the French Liquidator or any Subsidiary, Affiliate, representative or agent thereof, such Transfer Taxes shall be paid by the Purchaser or caused to be paid by the
Purchaser to such Seller, Joint Administrators, French Liquidator, Subsidiary, Affiliate or agent, as applicable, at the Closing or thereafter, as requested of or by the applicable Seller, Joint Administrators or French Liquidator. Upon request from
a Seller, the Joint Administrators or the French Liquidator, the Purchaser shall provide to such Seller, Joint Administrators or French Liquidator an original receipt (or such other evidence as shall be reasonably satisfactory to such Seller, Joint
Administrator or French Liquidator) evidencing the payment of Transfer Taxes by the Purchaser or, if relevant, any of the Purchaser’s limited partners to the applicable Tax
Authority under this Section 6.1. For the avoidance of doubt, the Purchaser shall remain liable in respect of any Transfer Taxes regardless of the date that the Assets are removed from the premises of a Seller or any Seller’s supplier. All
other Closing expenses will be paid by the Party incurring such expenses. 
 (b) If the
Purchaser or, if relevant, any of the Purchaser’s limited partners wishes to claim any exemption relating to, or a reduced rate of, or make an election with the effect of reducing,
or engage in any other transaction designed to reduce, Transfer Taxes, in connection with this Agreement or the transactions contemplated herein, or in connection with the execution of any other Transaction Document, the Purchaser shall be solely
responsible for ensuring that such exemption, reduction or election applies and, in that regard, shall provide the Sellers, Joint Administrators or French Liquidator (as applicable) prior to Closing with its permit number, GST/HST, VAT, provincial
sales taxes or other similar registration numbers or, if relevant, those of any of the Purchaser’s limited partners and/or any appropriate certificate of exemption, election and/or
other document or evidence to support the claimed entitlement to such exemption or reduction by the Purchaser or, if relevant, any of the Purchaser’s limited partners. All parties
shall make commercially reasonable efforts to cooperate to the extent necessary to obtain any such exemption or reduction. Notwithstanding the foregoing, any such cooperation to be provided in this Section 6.1(b) shall not include or extend to
(i) a liquidation or restructuring of a Seller or any business of a Seller, including the transfer of any assets or Assets or liabilities or Assumed Liabilities between the Sellers or their Affiliates, unless the Seller or the relevant
Affiliate is indemnified (prior to such liquidation or restructuring) against any cost or expense of such liquidation or restructuring to its satisfaction (acting at all times reasonably and in good faith); (ii) any action or omission that
would result in the imposition on any Seller or any Affiliate of any Seller of any additional Tax liability or making any additional payment to any Tax Authority or Government Entity in respect of Tax which is an Excluded Liability, unless

 
such Seller or Affiliate is (prior to the relevant action or omission) indemnified against such additional Tax liability or payment; (iii) any action or omission that would result in any
material out of pocket cost or expense for any Seller or any Affiliate of any Seller, unless such Seller or Affiliate is (prior to the relevant action or omission), indemnified against such cost or expense to their satisfaction (acting at all times
reasonably and in good faith) by the Purchaser; (iv) any action or omission which would cause the Sellers or any Affiliates of the Sellers to be in contravention of any applicable Law (including Bankruptcy Law) or published practice of a Tax
Authority; (v) changing the identity or Tax residence of any Sellers, the location of any Assets or Assumed Liabilities, the nature or extent of any Assets or Assumed Liabilities, the Assets or Assumed Liabilities to be transferred by any
particular Seller or the structure of the transaction as an asset sale rather than the sale of any form of entity, unless the Seller or the relevant Affiliate is indemnified (prior to such action) against any cost or expense of such action to its
satisfaction (acting at all times reasonably and in good faith); or (vi) any reduction in the obligations of the Purchaser or rights of the Sellers. 
 It is agreed and acknowledged that for the purposes of this Section 6.1, “Transfer Taxes” do not include VAT in respect of any supply (or deemed supply) of goods and services pursuant to
this Agreement, for which the provisions of Section 6.9 shall apply instead. 

 Exhibit III 
 Amendments to Section 6.9 
 SECTION 6.9. VAT. 

(a) All sums payable by the Purchaser under this Agreement
and/or which the Purchaser is required to pay or cause to be paid under Section 5.27(a) in respect of the Optioned Licenses shall be exclusive of VAT and, except
to the extent Section 6.9(d) applies, where a sum is paid by the Purchaser pursuant to this Agreement and/or paid or caused to be paid by the Purchaser under
Section 5.27(a) in respect of the Optioned Licenses in consideration for any supply (or deemed supply) of goods or services by any of the EMEA Sellers the Purchaser shall, in addition to the consideration payable for such supply,
pay or cause to be paid to the relevant EMEA Seller, on receipt of an appropriate VAT invoice, an amount equal to the VAT (if any) determined in accordance with Section 2.2.3(b)
as, or (as appropriate) determined by the relevant EMEA Seller(s) as arising in respect of such supply together with all interest and penalties thereon (except to the extent that such interest or penalties arise other than as a result of a failure
of the Purchaser to comply with any of its obligations pursuant to this Section 6.9), with payment to be made or caused to be made by the Purchaser within five (5) Business
Days of receipt of an appropriate valid VAT invoice or Closing (whichever is the later), provided that, no payment shall be due fromrequired to be made (or
caused to be made) by the Purchaser in respect of VAT pursuant to this Section 6.9(a) or Section 6.9(e) in circumstances where the EMEA Seller, the Joint Administrator or French Liquidator issues a VAT invoice to the Purchaser
or, if relevant, any of the Purchaser’s limited partners outside of any applicable time limits within which the Purchaser
(oror Purchaser’s limited partner (or in either case a member of its VAT group) can claim credit for the relevant input tax, and provided further
that, for the avoidance of doubt, any amount payable pursuant to this Section 6.9(a) in respect of any Optioned Licenses shall be an amount determined by the relevant EMEA Seller(s). 

(b) For the avoidance of doubt, and without prejudice to the generality of this Section 6.9, if the relevant EMEA Seller or Joint
Administrators or French Liquidator forms the view, acting reasonably, that the supply by the EMEA Sellers of any Assets or assumption from the EMEA Sellers of any Assumed Liabilities (if relevant) is subject to VAT, or that any other amounts
payable by the Purchaser or which the Purchaser is required to cause to be paid or any other supplies made to the Purchaser
or to any of the Purchaser’s limited partners (if relevant) in each case pursuant to this Agreement and/or in respect of the Optioned Licenses are subject to VAT, then, except to the extent Section 6.9(d) applies, the relevant EMEA
Seller(s) or the Joint Administrators or the French Liquidator shall be entitled to provide the Purchaser or any of the Purchaser’s limited partners (if relevant) with a VAT
invoice in respect of the supply in question. 
 (c) Subject to any contrary provision of this Agreement, a VAT invoice served
by any EMEA Seller or the Joint Administrators or the French Liquidator in good faith and in accordance with applicable VAT laws, absent manifest error, shall be accepted by the Purchaser
and the Purchaser’s limited partners (if relevant) as valid, including in relation to amounts of VAT stated in such invoice, except to the extent the Purchaser or any of the
Purchaser’s limited partners (if relevant) has paid the applicable VAT by virtue of Section 6.9(d) below. 

 (d) Where the liability for VAT in respect of any supply is a liability of the Purchaser
or any of the Purchaser’s limited partners (if relevant) (whether under Section 8 of the Value Added Tax Act 1994 or similar or equivalent provisions in any member of the
European Union) the Purchaser shall account for such VAT or shall cause such VAT to be accounted to the relevant Tax Authority within any applicable time limits. 

(e) In the event that an amount in respect of VAT is payable under the terms of this Agreement and/or in respect of the Optioned Licenses
in respect of a supply and: (1) the consideration amount as indicated on the relevant VAT invoice in respect of such supply differs from the actual consideration amount for that supply for VAT purposes (including, but not limited to, situations
where the Purchase Price is adjusted in accordance with any provision of this Agreement, and/or the allocation of the Purchase Price to any Assets or Assumed Liabilities is amended, whether pursuant to Section 2.2.3 or otherwise); (2) a
Tax Authority determines in writing that a supply by any EMEA Seller in respect of which the Purchaser has paid or has caused to be paid VAT should properly be characterized as a supply
on which VAT does not arise; or (3) for any reason the rate of VAT applicable to the supply in question is changed, then the relevant EMEA Seller(s) and the Purchaser agree to co-operate in good faith to
correct or cause to be corrected all relevant VAT invoices and VAT returns and (without prejudice to the generality of the foregoing): 

(i) where the purchase price for any Assets and/or Assumed Liabilities (if relevant) is increased, or VAT otherwise
becomes due, the Purchaser shall pay or shall cause to be paid to the relevant EMEA Seller (or relevant Tax Authority, where applicable) an amount equal to any additional VAT
that becomes due as a result of such increase with payment to be made or caused to be made by the Purchaser within five (5) Business Days of receipt of an appropriate valid VAT
invoice or Closing, whichever is the later; and 
 (ii) where the purchase price for any Assets and/or Assumed
Liabilities (if relevant) is decreased, or to the extent that a relevant Tax Authority determines in writing that a supply by any EMEA Seller in respect of which the Purchaser
has paid or caused to be paid an amount in respect of VAT should properly be characterised as a supply on which
VAT does not arise, or where the rate of VAT applicable to the supply in question is decreased, or where the Purchaser has
otherwise paid or caused to be paid an amount in respect of VAT to an EMEA Seller under Section 6.9(a)
that was not due, the relevant EMEA Seller shall, without unreasonable delay, issue an appropriate and valid VAT credit note or equivalent to the Purchaser or the Purchaser’s limited
partner (if relevant) and shall use its reasonable endeavors to recover the Excess VAT and, to the extent the Excess VAT is actually recovered and retained by it (or by any member of its VAT group) or is creditable by any EMEA Seller against any
VAT liability of an EMEA Seller (or is so creditable by any member of its VAT group), the relevant EMEA Seller shall, without unreasonable delay, pay such Excess VAT to the Purchaser, and for the purposes of this Section 6.9(e)(ii),
“Excess VAT” means the amount in respect of VAT actually paid (after deducting any previous refund under this Section 6.9(e)(ii)) or caused to be paid by
the Purchaser that should not have been paid or caused to be paid, taking into account the decrease in purchase 

 
price, the incorrect characterization of a supply, the decrease in the VAT rate or the amount in respect of VAT that was paid to an EMEA Seller that was otherwise not due. 

(f) The EMEA Sellers, Joint Administrators, French Liquidator and the Purchaser agree to act in good faith in accordance with
Section 2.2.3 for all purposes relating to VAT (including the preparation and filing of any VAT invoices or Tax Returns with respect to VAT). 
 (g) If it is not possible for the EMEA Sellers, Joint Administrators, French Liquidator and the Purchaser in accordance with Section 2.2.3 to determine before the date falling five (5) Business
Days prior to Closing an amount of consideration for the purposes of VAT invoicing (notwithstanding that the Purchaser has not by such date delivered a proposed Partial Allocation pursuant to Section 2.2.3(b)) and in all cases in respect of all
sums payable in respect of any Optioned Licenses, then: 
 (i) where any of the EMEA Sellers, the Joint
Administrators or the French Liquidator are required to account to a Tax Authority for VAT in respect of the supply of any goods or services under this Agreement and/or in respect of the Optioned Licenses, subject to Section 6.9(e), the
determination of the relevant EMEA Seller or the Joint Administrators or the French Liquidator (in each case, acting reasonably) shall be accepted by the parties for VAT purposes in respect of such goods or services until and unless replaced
pursuant to Section 6.9(e); and 
 (ii) where the Purchaser is required to
account or to cause to be accounted to a Tax Authority for VAT in respect of the supply of any goods or services under this Agreement and/or in respect of the Optioned Licenses, subject
to Section 6.9(e), the determination of the Purchaser (acting reasonably) shall be accepted by the parties for VAT purposes in respect of such goods or services unless and until replaced pursuant to Section 6.9(e).2010 Employee Stock Purchase Plan, as amended

 6. Payroll Deductions. 

(a) Payroll deductions for a Participant shall commence on the first payroll following the Enrollment Date and shall end on the last
payroll in the Offering Period as to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10 hereof. 
 (b) At the time a Participant files his or her Subscription Agreement with the Company, he or she shall elect to have payroll deductions made on each payday during the next Offering Period at a percentage
rate equal to a positive whole number not exceeding 15%, or such other maximum rate as may be determined from time to time by the Board subject to the provisions of Section 19 hereof, of the Compensation which would otherwise be payable to such
Participant on each such payday. 
 (c) Payroll deductions for a Participant shall commence on the first payday following the
date on which a Participant’s payroll deduction authorization becomes effective and shall automatically continue from Offering Period to Offering Period until changed or terminated by the Participant in accordance with the terms hereof.

 (d) All payroll deductions authorized by a Participant pursuant to a Subscription Agreement, as modified pursuant to
Section 5, shall be credited to the Participant’s individual account under the Plan. A Participant may not make any additional payments into such account. 
 (e) A Participant may change the rate of his or her payroll deduction during an Offering Period only as follows: 
 (i) A Participant may decrease the rate of payroll deductions for a future Purchase Period within an existing Offering Period or for a future Offering Period only by completing and submitting, by the
specified administrative deadline prior to the commencement of such future Purchase Period or Offering Period, a signed Payroll Deduction Authorization Change or Withdrawal Form. 

(ii) A Participant may increase the rate of payroll deductions for a future Offering Period only by completing and submitting, by the
specified administrative deadline prior to the commencement of such Offering Period, a signed Payroll Deduction Authorization Change or Withdrawal Form. An election to increase the rate of payroll deductions may be made for new Offering Periods that
will begin for any reason, including new Offering Periods that will begin as a result of (i) enrollment in a new Offering Period following the end of the final Purchase Period in an existing Offering Period or (ii) an employee’s
voluntary election to withdraw from a current Offering Period and to enroll in a new Offering Period. 
 (iii) A Participant
may not increase the rate of payroll deductions for a future Purchase Period within an existing Offering Period. In order for such a Participant to increase the rate of payroll deductions prior to a future Offering Period that follows the

  
 -5-

 
expiration of his or her existing Offering Period, the Participant must terminate his or her participation in the existing Offering Period and then enroll in a new Offering Period, subject to the
limitations set forth in Section 5 above. In no event may a Participant increase the rate of payroll deductions for a future Purchase Period by completing a Purchase Period within an existing Offering Period that is not otherwise expiring and
then immediately participating in a new Offering Period. 
 7. Grant of Option. On the Enrollment Date of each Offering
Period, each Participant in such Offering Period shall automatically be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of shares of the Company’s Common Stock
determined by dividing such Employee’s payroll deductions accumulated prior to such Exercise Date and retained in the Participant’s account as of the Exercise Date by the applicable Purchase Price; provided, however, that in
no event shall an Employee be permitted to purchase during each Purchase Period more than a number of shares determined by dividing $12,500 by the Fair Market Value of a share of the Company’s Common Stock (subject to any adjustment pursuant to
Section 19) on the Enrollment Date; and provided further that such grant of options and purchase shall be subject to the limitations set forth in Sections 3(b) and 12 hereof. The preceding limitation (multiplied by four)
shall also apply with respect to each Offering Period. The Board may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of the Company’s Common Stock an Employee may purchase during each
Purchase Period of an Offering Period. Exercise of the option shall occur as provided in Section 8 hereof, unless the Participant has withdrawn pursuant to Section 10 hereof. The option shall expire on the last day of the Offering Period.

 8. Exercise of Option. 
 (a) Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of shares shall be exercised automatically on each Exercise Date of the Offering Period,
and the accumulated payroll deductions credited to a Participant’s account on the Exercise Date will be applied to purchase whole shares of the Company’s Common Stock (up to the maximum number subject to option as determined in
Section 7(a) hereof) at the Purchase Price. Any amount credited to a Participant’s account and not applied to the purchase of Common Stock by reason of the limitation on the number of shares subject to option shall be refunded promptly to
such Participant after the Exercise Date, provided that any amount remaining in a Participant’s account and representing a fractional share shall be carried over and applied to the purchase of shares in the subsequent Purchase Period or
Offering Period if the Participant participates in the subsequent offering. During his or her lifetime, a Participant’s option to purchase shares hereunder is exercisable only by the Participant. 

(b) If the Board determines that, on a given Exercise Date, the number of shares with respect to which options are to be exercised may
exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of shares available for sale under the Plan on such

  
 -6-

 
Exercise Date, the Board may in its sole discretion (x) provide that the Company shall make a pro rata allocation of the shares of Common Stock available for purchase on such Enrollment Date
or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue
all Offering Periods then in effect, or (y) provide that the Company shall make a pro rata allocation of the shares available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable
and as it shall determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 19 hereof.
The Company may make a pro rata allocation of the shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the
Company’s shareholders subsequent to such Enrollment Date. In the event of any pro rata allocation of shares, the Company shall give written notice of such allocation to each Participant affected thereby and shall reduce the rate of payroll
deductions, if necessary. 
 9. Delivery. As promptly as practicable after each Exercise Date on which a purchase of
shares occurs, the Company shall arrange for the issuance and delivery to, or credit to the account of, each Participant, as appropriate, of the shares purchased upon exercise of his or her option. At the election of the Company, the issuance and
delivery of the shares purchased upon exercise of a Participant’s option may be effected by transfer (electronic or otherwise in the discretion of the Company) of such shares to a securities account maintained in the Participant’s name.

 10. Withdrawal; Termination of Employment. 
 (a) A Participant may terminate his or her participation in the Plan and withdraw from an Offering by completing and submitting, by the specified administrative deadline prior to the end of a Purchase
Period, a signed Payroll Deduction Authorization Change or Withdrawal Form. Any such termination and withdrawal may be made effective (i) immediately, in which case all withheld amounts will be refunded to the Participant, or (ii) as of
the first day of the next Purchase Period, in which case withheld amounts will be applied to the purchase of shares at the end of the Purchase Period in which the election is made and any excess funds not so applied will be refunded to the
Participant following the purchase. If a Participant terminates his or her participation in the Plan pursuant to this Section 10(a), payroll deductions shall not resume at the beginning of a succeeding Offering Period unless the Participant
delivers a new Subscription Agreement in accordance with Section 5 hereof. 
 (b) Upon termination of a Participant’s
employment for any reason, including retirement or death, as soon as practicable after such termination, the payroll deductions credited to his or her account shall be returned to him or her or, in the case of his or her death, to the person or
persons entitled thereto under Section 14, and his or her option shall be automatically canceled. 

  
 -7-

 (c) In the event an Employee fails to remain in the continuous employ of the Company or its
Subsidiaries for more than 20 hours per week during the Offering Period in which the Employee is a Participant, he or she will be deemed to have elected to withdraw from the Plan and the payroll deductions credited to his or her account
will be returned to him or her and his or her option will be canceled. 
 (d) A Participant’s withdrawal from an offering
shall not have any effect upon his or her eligibility to participate in a subsequent offering or in any similar plan which may hereafter be adopted by the Company. 
 11. Interest. No interest shall accrue on the payroll deductions of a Participant in the Plan. 
 12. Stock. 
 (a) The maximum number of shares of the Company’s Common
Stock which shall be made available for sale under the Plan shall be 500,000 shares, subject to adjustment upon changes in capitalization of the Company as provided in Section 18(a) hereof, together with a cumulative annual increase to the
number of shares reserved for issuance thereunder on May 1, 2010 and each May 1 thereafter equal to the lesser of (i) 500,000 shares, (ii) 1% of the outstanding shares of the Company on the last day of the prior fiscal year or
(iii) such amount as may be determined by the Board. The shares to be sold to Participants in the Plan will be authorized but unissued shares. Upon the cancellation of any option granted under the Plan, the shares subject thereto shall return
to the Plan and become available for options thereafter granted under the Plan. 
 (b) A Participant will have no interest or
voting right in shares covered by his or her option until such option has been exercised. 
 (c) Shares to be delivered to a
Participant under the Plan shall, as specified in the Participant’s Subscription Agreement, be registered in the name of the Participant or in the name of the Participant and his or her spouse. 

13. Administration. The Plan shall be administered by the Board or a committee of members of the Board appointed by the Board. The
Board or its committee shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the fullest extent permitted by law, be final and binding upon all parties. 
 14. Designation of Beneficiary. 
 (a) A Participant may file a written
designation of a beneficiary who is to receive any shares and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to the Exercise Date on which an option is exercised but prior to
delivery to him or her of such shares and cash. In addition, a Participant may file a 

  
 -8-

 
written designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option.
If a Participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. 
 (b) Such designation of beneficiary may be changed by the Participant at any time by written notice. In the event of the death of a Participant and in the absence of a valid designation of a beneficiary
who is living at the time of such Participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the Participant; or if no such executor or administrator has been appointed (to the
knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant; or if no spouse, dependent or relative is known to the Company, then to
such other person as the Company may designate. 
 15. Transferability. Neither payroll deductions credited to a
Participant’s account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and
distribution, pursuant to a qualified domestic relations order as defined by the Code or Title I of the Employee Retirement Income Security Act, or the rules thereunder, or as provided in Section 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof. 

16. Use of Funds. All payroll deductions received or held by the Company on behalf of a Participant under the Plan may be used by
the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 
 17.
Reports. Individual accounts will be maintained for each Participant in the Plan. Individual statements of account will be given to participating Employees at least annually, which statements shall set forth the amounts of payroll deductions,
the Purchase Price, the number of shares purchased and the remaining cash balance, if any, in a Participant’s account. 

18. Adjustments upon Changes in Capitalization or Control. 

(a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of shares of Common
Stock covered by each option under the Plan which has not yet been exercised and the number of shares of Common Stock which has been authorized for issuance under the Plan but has not yet been placed under option or which has been returned to the
Plan upon the cancellation of an option, as well as the option price per share of Common Stock covered by each option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination of the Common Stock, or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been 

  
 -9-

 
“effected without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of
Common Stock subject to option. 
 (b) Dissolution or Liquidation. In the event of the proposed dissolution or
liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the consummation of such proposed dissolution or
liquidation, unless provided otherwise by the Board. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Board shall notify each Participant in writing, at least ten business days prior to
the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option shall be exercised automatically on the New Exercise Date, unless prior to such date the
Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 
 (c) Merger or Asset Sale. In
the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding option shall be assumed or an equivalent option substituted by the successor
corporation or a parent or subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, any Purchase Periods then in progress shall be shortened by setting a new Exercise Date
(the “New Exercise Date”) and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date of the Company’s proposed sale or merger. The Board shall notify each Participant
in writing, at least ten business days prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option shall be exercised automatically on the
New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof. 
 (d) No fractional shares of Common Stock shall be issuable on account of any adjustment described herein, and the aggregate number of shares into which shares then covered by an option, when changed as
the result of such adjustment, shall be reduced to the largest number of whole shares resulting from such adjustment, unless the Board, in its sole discretion, shall determine to issue scrip certificates in respect to any fractional shares, which
scrip certificates, in such event, shall be in a form and have such terms and conditions as the Board in its discretion shall prescribe. 
 19. Amendment or Termination. The Board of Directors of the Company may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18 hereof, no such termination
can affect options previously granted, provided that an Offering Period may be terminated by the Board of Directors on any Exercise Date if the Board determines that the termination of the Offering Period or the Plan is in the best interests of the
Company and its shareholders. Except as provided in Section 18 and this Section 19, no amendment may make 

  
 -10-

 
any change in any option theretofore granted which adversely affects the rights of any Participant without the prior written consent of such Participant: 

(a) To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law,
regulation or stock exchange rule), the Company shall obtain shareholder approval of any amendment to the Plan in such a manner and to such a degree as is required. 
 (b) Without shareholder approval and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Board (or its committee) shall be entitled to
change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding
in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and
crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as
the Board (or its committee) determines in its sole discretion advisable which are consistent with the Plan. 
 (c) In the event
the Board determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Board may, in its discretion and to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such
accounting consequence including, but not limited to: 
 (i) altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase Price; 
 (ii) shortening any
Offering Period so that Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the Board action; and 
 (iii) allocating shares. 
 Such modifications or amendments shall not require
shareholder approval or the consent of any Plan Participants. 
 20. Term of Plan. The Plan shall become effective upon
the earlier to occur of its adoption by the Board or its approval by vote of a majority of the outstanding shares of the Company entitled to vote on the adoption of the Plan. The Plan shall continue in effect for a term of ten years unless sooner
terminated under Sections 19 or 22 hereof. 
 21. Notices. All notices or other communications (i) by a
Participant to the Company in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the

  
 -11-

 
receipt thereof and (ii) by the Company to a Participant in connection with the Plan shall be deemed to have been duly given when received by the Participant or, if earlier, five days after
deposit in the United States mail by certified or registered mail, return receipt requested, first class postage prepaid, addressed to the Participant at his or her address as shown on the records of the Company or as such Participant may request by
written notice to the Company hereunder. 
 22. Shareholder Approval. Notwithstanding anything to the contrary herein,
the effectiveness of the Plan shall be expressly subject to approval by the Company’s shareholders prior to November 1, 2010 by the affirmative vote of the holders of a majority of the outstanding shares of stock of the Company present or
represented and entitled to vote thereon at a shareholder meeting duly held or by written consent in accordance with applicable law. 
 23. No Enlargement of Employee Rights. The Plan is purely voluntary on the part of the Company, and the continuance of the Plan shall not be deemed to constitute a contract between the Company and
any Employee, or to be consideration for or a condition of the employment of any Employee. Nothing contained in this Plan shall be deemed to give any Employee the right to be retained in the employ of the Company, its parent, Subsidiary or a
successor corporation, or to interfere with the right of the Company or any such corporations to discharge or retire any Employee thereof at any time. No Employee shall have any right to or interest in options authorized hereunder prior to the grant
of an option to such Employee, and upon such grant he or she shall have only such rights and interests as are expressly provided herein, subject, however, to all applicable provisions of the Company’s Articles of Incorporation, as the same may
be amended from time to time. 
 24. Information to Participants. The Company shall provide without charge to each
Participant in the Plan copies of such annual and periodic reports as are provided by the Company to its shareholders generally. 
 25. 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 conflicts of laws rules thereof. 
 26. Tax Withholding. If at any time the Company or
any Subsidiary is required, under applicable laws and regulations, to withhold, or to make any deduction of, any taxes or take any other action in connection with any exercise of an option granted hereunder or any disposition of shares of Common
Stock issued hereunder, the Participant must make adequate provision for the Company’s federal, state or other tax withholding obligations which arise from such exercise or disposition. The Company or such Subsidiary shall have the right to
deduct or withhold from the Participant’s compensation the amount necessary for the Company to meet applicable withholding obligations. 
 27. Securities Law Compliance. No shares of Common Stock may be issued upon the exercise of any option under the Plan until all requirements of applicable Federal, state, foreign or other
securities laws with respect to the purchase, sale and issuance of shares of Common Stock shall have been satisfied. If any action must be taken because of such requirements, then 

  
 -12-

 
the purchase, sale and issuance of shares shall be postponed until such action can reasonably be taken. Upon request by the Company, an Employee shall deliver to the Company such information,
representations or undertakings as the Company may reasonably request in order to comply with any registration requirements or exemptions therefrom of applicable securities laws. The Company may require any securities so issued to bear a legend, may
give its transfer agent instructions, and may take such other steps as in its judgment are reasonably required to prevent any violation of applicable securities laws.
