 IQ ENGINES, INC. 

2008 STOCK OPTION PLAN 

STOCK OPTION AGREEMENT – NSO 

1. Grant of Option. IQ Engines, Inc., a Delaware corporation (the “Company”), hereby grants to Name of
Consultant (“Optionee”), an option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”) set forth in the Notice of Stock Option Grant (the “Notice”),
at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions and provisions of the IQ Engines, Inc. 2008 Stock Option Plan (the “Plan”) adopted by the Company,
which is incorporated in this Agreement by reference. Unless otherwise defined in this Agreement, the terms used in this Agreement shall have the meanings defined in the Plan. 

2. Designation of Option. This Option is intended to be an Incentive Stock Option as defined in Section 422 of the
Code only to the extent so designated in the Notice, and to the extent it is not so designated or to the extent this Option does not qualify as an Incentive Stock Option, it is intended to be a Nonstatutory Stock Option. 

Notwithstanding the above, if designated as an Incentive Stock Option, in the event that the Shares subject to this Option (and all other
Incentive Stock Options granted to Optionee by the Company or any Parent or Subsidiary, including under other plans of the Company) that first become exercisable in any calendar year have an aggregate Fair Market Value (determined for each Share as
of the date of grant of the option covering such Share) in excess of $100,000, the Shares in excess of $100,000 shall be treated as subject to a Nonstatutory Stock Option, in accordance with Section 5(c) of the Plan. 

3. Exercise of Option. This Option shall be exercisable during its term in accordance with the Vesting/Exercise Schedule
set out in the Notice and with the provisions of Section 10 of the Plan as follows: 
 (a) Right to Exercise. 

(i) This Option may not be exercised for a fraction of a share. 

(ii) In the event of Optionee’s death, Disability or other termination of Continuous Service Status, the exercisability of this Option
is governed by Section 5 below, subject to the limitations contained in this Section 3. 
 (iii) In no event may this Option be
exercised after the Expiration Date set forth in the Notice. 
 (b) Method of Exercise. 

(i) This Option shall be exercisable by execution and delivery of the Exercise Agreement attached hereto as Exhibit A or of any
other form of written notice approved 

 
for such purpose by the Company which shall state Optionee’s election to exercise this Option, the number of Shares in respect of which this Option is being exercised, and such other
representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be delivered to
the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written notice shall be accompanied by payment of the aggregate Exercise Price for the purchased Shares. 

(ii) As a condition to the exercise of this Option and as further set forth in Section 12 of the Plan, Optionee agrees to make adequate
provision for federal, state or other tax withholding obligations, if any, which arise upon the grant, vesting or exercise of this Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise. 

(iii) The Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise of this Option
unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised until such time as the Plan has been approved by the
holders of capital stock of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such Shares would constitute a violation of any Applicable Laws, including any applicable U.S. federal or
state securities laws or any other law or regulation, including any rule under Part 221 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company
may require Optionee to make any representation and warranty to the Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which this
Option is exercised with respect to such Shares. 
 (iv) Subject to compliance with Applicable Laws, this Option shall be deemed to be
exercised upon receipt by the Company of the appropriate written notice of exercise accompanied by the Exercise Price and the satisfaction of any applicable withholding obligations. 

4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination of the following,
at the election of Optionee: 
 (a) cash or check; 

(b) cancellation of indebtedness; 

(c) at the discretion of the Plan Administrator on a case by case basis, by surrender of other shares of Common Stock of the Company (either
directly or by stock attestation) that Optionee previously acquired and that have an aggregate Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which this Option is being exercised; or 

(d) at the discretion of the Plan Administrator on a case by case basis, by Cashless Exercise.

 5. Termination of Relationship. Following the date of termination of
Optionee’s Continuous Service Status for any reason (the “Termination Date”), Optionee may exercise this Option only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise
this Option as of the Termination Date, or if Optionee does not exercise this Option within the Termination Period set forth in the Notice or the termination periods set forth below, this Option shall terminate in its entirety. In no event, may any
Option be exercised after the Expiration Date of this Option as set forth in the Notice. 
 (a) Termination. In the
event of termination of Optionee’s Continuous Service Status other than as a result of Optionee’s Disability or death, Optionee may, to the extent Optionee is vested in the Option Shares at the date of such termination (the
“Termination Date”), exercise this Option during the Termination Period set forth in the Notice. 
 (b) Other
Terminations. In connection with any termination other than a termination covered by Section 5(a), Optionee may exercise this Option only as described below: 

(i) Termination upon Disability of Optionee. In the event of termination of Optionee’s Continuous Service Status as a
result of Optionee’s Disability, Optionee may, but only within twelve (12) months following the Termination Date, exercise this Option to the extent Optionee was vested in the Option Shares as of such Termination Date. 

(ii) Death of Optionee. In the event of termination of Optionee’s Continuous Service Status as a result of Optionee’s
death, or in the event of Optionee’s death within twelve (12) months following Optionee’s Termination Date, this Option may be exercised at any time within twelve (12) months following the date of death (or, if earlier, the date
Optionee’s Continuous Service Status terminated) by Optionee’s estate or by a person who acquired the right to exercise this Option by bequest or inheritance, but only to the extent Optionee was vested in this Option as of the Termination
Date. 
 (iii) Termination for Cause. In the event of termination of Optionee’s Continuous Service Status for Cause,
this Option (including any vested portion thereof) shall immediately terminate in its entirety upon first notification to Optionee of such termination for Cause. If Optionee’s Continuous Service Status is suspended pending an investigation of
whether Optionee’s Continuous Service Status will be terminated for Cause, all Optionee’s rights under this Option, including the right to exercise this Option, shall be suspended during the investigation period. 

(c) Right of Repurchase. Following termination of your Continuous Service Status for any reason, the Company shall have the
right to purchase all of those Shares that you have or will acquire under this Option. If the Company exercises its right to purchase such Shares, the purchase price shall be the Fair Market Value of those Shares on the date of purchase as
determined in good faith by the Board and shall be paid in cash. The Company will notify you of its intention to purchase such Shares, and will consummate the purchase within the period established by applicable law. The Company’s
right of repurchase shall terminate in the event that the Shares are listed on an established stock exchange or quoted regularly on the NASDAQ National Market. 

  
 3 

 6. Non-Transferability of Option. This Option may not be transferred in any
manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and
assigns of Optionee. 
 7. Lock-Up Agreement. In connection with the initial public offering of the
Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby agrees not to sell, make any short sale of, loan, grant any option for the purchase
of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of
time (not to exceed 180 days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of
the public offering. 
 8. Corporate Transaction. Notwithstanding the above, one hundred percent (100%) of
the Shares subject to this Option shall become fully exercisable in the event that: (a) your employment is terminated by an acquiring company in connection with, or as a result of, a Change in Control (as defined below) or (b) you resign
due to the fact that an acquiring company in connection with, or as a result of, a Change in Control relocates your place of employment more than one hundred miles from the city limits of Berkeley, CA which relocation is not agreed to by you. In the
event that the acquiring company terminates your employment as of or after the effective date of a Change of Control and the stated reason for such termination is for reasons unrelated to such Change of Control, this Option shall not accelerate and
become fully exercisable unless you can show by clear and convincing evidence that such termination was in connection with, or as a result of, a Change of Control. The foregoing provisions shall not restrict in any way the Company’s or any
acquiring company’s right to discharge you for any reason.  
 For purposes of this Option, “Change in
Control” shall be defined as the occurrence of any of the following events: 
 (a) the consummation of a merger, consolidation
or other reorganization of the Company (other than a reincorporation of the Company), if after giving effect to such merger, consolidation or other reorganization of the Company, the shareholders of the Company immediately prior to such merger,
consolidation or other reorganization do not represent a majority in interest of the holders of voting securities (on a fully diluted basis) with the ordinary voting power to elect directors of the surviving or resulting entity after such merger,
consolidation or other reorganization; 
 (b) the sale, lease or other disposition of all or substantially all of the assets of the Company
to a third party who is not an affiliate (including a Parent or Subsidiary) of the Company; 
 (c) the dissolution of the Company pursuant
to action validly taken by the shareholders of the Company in accordance with applicable state law; or 
 (d) the occurrence of any other
tender offer, merger, consolidation, sale, reorganization, dissolution or other such event or series of events, which in the opinion of a majority of the Board (as reflected in a written resolution of the Board) has resulted in a change of control
of the Company. 

  
 4 

 9. Effect of Agreement. Optionee acknowledges receipt of a copy of the Plan
and represents that he or she is familiar with the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be bound by its contractual terms as set forth
herein and in the Plan. Optionee hereby agrees to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to this Option. In the event of a conflict between the terms and
provisions of the Plan and the terms and provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. 

10. Miscellaneous. 

(a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law. 

(b) Entire Agreement; Enforcement of Rights. This Agreement, together with the Notice of Stock Option Grant to which this
Agreement is attached and the Plan, sets forth the entire agreement and understanding of the parties relating to the subject matter herein and therein and merges all prior discussions between the parties. Except as contemplated under the Plan, no
modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement
shall not be construed as a waiver of any rights of such party. 
 (c) Severability. If one or more provisions of this
Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of this Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of this Agreement shall be enforceable in accordance with
its terms. 
 (d) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed
sufficient when delivered personally or sent by telegram or fax or forty-eight (48) hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such
party’s address as set forth below or as subsequently modified by written notice. 
 (e) Counterparts. This Option may be
executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument.

 EXHIBIT A 

IQ ENGINES, INC. 
 2008
STOCK OPTION PLAN 
 EXERCISE AGREEMENT 

This Exercise Agreement (this “Agreement”) is made as of
                    , by and between IQ Engines, Inc., a Delaware corporation (the “Company”), and Name of Consultant
(“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the Company’s 2008 Stock Option Plan (the “Plan”). 

1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to exercise his or her option
to purchase          shares of the Common Stock (the “Shares”) of the Company under and pursuant to the Plan and the Stock Option Agreement granted
                     (the “Option Agreement”). The purchase price for the Shares shall be
$         per Share for a total purchase price of $        . The term “Shares” refers to the purchased Shares and all securities received as stock
dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other property to which Purchaser is entitled by
reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of
the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of this Agreement, the payment of the aggregate exercise price by any method listed in Section 4 of the Option
Agreement, and the satisfaction of any applicable tax withholding obligations, all in accordance with the provisions of Section 3(b) of the Option Agreement. The Company shall issue the Shares to Purchaser by entering such Shares in
Purchaser’s name as of such date in the books and records of the Company or, if applicable, a duly authorized transfer agent of the Company, against payment of the exercise price therefor by Purchaser. If applicable, the Company will deliver to
Purchaser a certificate representing the Shares as soon as practicable following such date. 
 3. Limitations on
Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the provisions below and applicable
securities laws. 
 (a) Right of First Refusal. Before any Shares held by Purchaser or any transferee of Purchaser
(either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the
Shares on the terms and conditions set forth in this Section 3(a) (the “Right of First Refusal”). 
 (i) Notice
of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser or 

 
other transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed
sale or transfer. The Holder shall offer the Shares at the same price (the “Purchase Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 

(ii) Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company
and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the Purchase Price. If the Purchase Price
includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board in good faith. 

(iii) Payment. Payment of the Purchase Price shall be made, at the election of the Company or its assignee(s), in cash (by
check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within sixty (60) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 

(iv) Holder’s Right to Transfer. If all of the Shares proposed in the Notice to be transferred to a given Proposed
Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3(a), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Purchase Price or at a higher price, provided
that such sale or other transfer is consummated within one hundred twenty (120) days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable securities laws and the
Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee
within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the
Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (v) Exception for Certain Family
Transfers. Anything to the contrary contained in this Section 3(a) notwithstanding, and provided that such transfer complies with applicable securities laws, the transfer of any or all of the Shares during Purchaser’s lifetime or
on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of Purchaser’s Immediate Family shall be exempt from the provisions of this Section 3(a). “Immediate Family” as
used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 3, and
there shall be no further transfer of such Shares except in accordance with the terms of this Section 3. 
 (b) Company’s
Right to Purchase upon Involuntary Transfer. In the event of any transfer by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(a)(v) above)
of all or a portion of the Shares by the record holder thereof, the Company shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of
the Shares on the date of transfer (as 

  
 2 

 
determined by the Board). Upon such a transfer, the person acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be
provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by the person acquiring the Shares. 

(c) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or in part to any holder or
holders of capital stock of the Company or other persons or organizations. 
 (d) Restrictions Binding on Transferees. All
transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions of this Agreement are
satisfied. 
 (e) Termination of Rights. The right of first refusal granted the Company by Section 3(a) above and the
option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon the first sale of Common Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in Section 3(a) above the
Company will remove any stop-transfer notices referred to in Section 5(b) below and related to the restrictions in this Section 3 and, if certificates are issued, a new certificate or certificates representing the Shares not repurchased
shall be issued, on request, without the legend referred to in Section 5(a)(ii) below and delivered to Purchaser. 
 4.
Investment and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the following: 

(a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the
Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in connection with, any
“distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 

(b) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (c) Purchaser
further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands
that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or
such registration is not required in the opinion of counsel for the Company. 

  
 3 

 (d) Purchaser is familiar with the provisions of Rules 144 and 701, each promulgated under
the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to
the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require, among other things,
that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under
certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph
(e) below. 
 (e) Purchaser further understands that in the event all of the applicable requirements of Rule 144 or 701 are not
satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities
and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 

(f) Purchaser understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or disposition of the
Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax advice. 

5. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. The certificate or certificates representing the Shares shall bear the following legends (as well as any legends
required by applicable state and federal corporate and securities laws): 
  

	 	(i)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION
THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933. 

  
 4 

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE HOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

 (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure compliance with the restrictions
referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own
records. 
 (c) Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have
been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall
have been so transferred. 
 6. No Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever
the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 

7. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of
the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the
Company however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one hundred eighty
(180) days) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public
offering. 
 8. Miscellaneous. 

(a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties
hereto shall be governed, construed and interpreted in accordance with the laws of the State of California without giving effect to principles of conflicts of law. 

(b) Entire Agreement; Enforcement of Rights. This Agreement sets forth the entire agreement and understanding of the parties
relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to
this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

  
 5

 Exhibit 4.4 

IQ ENGINES, INC. 

OPTION HOLDER NOTICE AND ACKNOWLEDGEMENT 

As you know, IQ Engines, Inc. (the “Company”) has entered into an Agreement and Plan of Merger with Yahoo! Inc. (“Parent”)
and certain other parties thereto, dated August 21, 2013 (the “Merger Agreement”), which will result in the Company becoming a wholly-owned subsidiary of Parent (the “Merger”). The Merger is expected to close
as early as August 23, 2013, subject to customary closing conditions (the actual time for consummation of the Merger, the “Effective Time”). 

What follows is a description of the treatment in the Merger of outstanding options to purchase Company common stock (“Company Options”)
granted under the Company’s 2008 Stock Option Plan, as in effect from time to time (the “Plan”). Please read this notice carefully. Additionally, and in order to timely process and deliver any cash payments or substituted
Parent stock options to which you might become entitled with respect to your Company Options following the Effective Time, please sign and return this Notice and Acknowledgement to the Company by Thursday, August 22, 2013. 

General Background on the Merger Consideration and Indemnification Obligations 

Based on an estimated closing date of Friday, August 23, 2013, holders of Company common stock will receive approximately $0.92731 per share in
consideration for their shares in the Merger (the “Per Share Amount”); however, this number is only an estimate and the actual per share consideration received by holders of Company common stock could be higher or lower. 

Not all of the Per Share Consideration will be distributed to the holders of Company common stock on or immediately following the Effective Time. A portion of
the aggregate Merger consideration will be withheld by Parent (the “Indemnity Holdback Amount”) in order to secure Parent’s rights of indemnification for, among other things, breach of the representations, warranties, covenants
and agreements in the Merger Agreement. An additional portion of the aggregate Merger consideration will be withheld by Parent (the “Expense Holdback Amount”) in order to fund the expenses of the representative of the Company’s
stockholders in connection with the performance of its duties under Article 9 of the Merger Agreement. Holders of vested Company Options who become entitled to receive a cash-out payment in connection with the cancellation of their options (as
discussed below) will contribute to the Indemnity Holdback Amount and Expense Holdback Amount pro-rata based on the amount of the aggregate Merger consideration that such individual is otherwise entitled to receive relative to all other holders.
Each holder’s pro-rata share of the Indemnity Holdback Amount and Expense Holdback Amount will be paid to him or her (less applicable withholding taxes) if and to the extent such amounts are released and not otherwise withheld by Parent or used
by the stockholder representative, as applicable, at the same time that such holdback amounts are released to all holders of Company equity interests subject to the holdback. The term of the indemnity holdback is generally 12 months. 

  
 1 

 In certain circumstances, the Merger Agreement provides that Parent may be able to seek indemnification from
holders of Company common stock and vested Company Options in excess of the Indemnity Holdback Amount. In these circumstances, the maximum amount payable by any such holder would be equal to the amount of the total Merger consideration received by
such holder; provided, that, there is no limit on the damages Parent can seek to recover from any holder in connection with such holder’s own fraud, willful breach or intentional misrepresentation or fraud, willful breach or intentional
misrepresentation by or on behalf of the Company that such holder participated in or had actual knowledge of. These provisions are described in detail in Article 9 of the Merger Agreement. 

Treatment of Company Options 
 Vested Company
Options 
 If You Do Not Wish to Exercise Your Vested Company Options Prior to Effective Time 

Parent will not assume any Company Options that are vested as of the Effective Time (“Vested Options”). The Merger Agreement provides that
each unexercised Vested Option outstanding as of the Effective Time will be cancelled and converted into the right to receive (less all applicable withholding taxes): 
  

	 	•	 	Promptly After the Effective Time: an amount in cash equal to the Per Share Amount multiplied by the number of shares of Company common stock subject to such Vested Options minus (a) the aggregate
exercise price of all shares subject to such Vested Options and (b) the pro rata share of the Indemnity Holdback Amount and Expense Holdback Amount, to be paid as soon as reasonably practicable after the Effective Time, and 

 

	 	•	 	Twelve Months or More After the Effective Time: an additional cash amount equal to any portion of the pro rata share of the Indemnity Holdback Amount and Expense Holdback Amount required to be made from the
holdback funds, as and when such disbursements are required to be made in accordance with the Merger Agreement. 

 No payment shall be made
with respect to any Vested Option with a per share exercise price that equals or exceeds the amount of the Per Share Amount. 
 You may be requested to
complete a letter of transmittal and other ancillary documents to facilitate the payments in respect of your Vested Options. All payments in respect of Vested Options will be reduced by all applicable withholding taxes. Tax withholding will apply
only when payments are made to you, either at, or shortly after the Effective Time, or when such funds are released to you from the holdback funds. For U.S. taxpayers, please note that payments received in exchange for the cancellation of Vested
Options constitute ordinary income (in the case of current and former employees, subject to income and employment tax withholding) regardless of whether the Vested Option was an incentive stock option or nonstatutory stock option under federal tax
laws.

 By timely signing and returning this Notice and Acknowledgement, you understand, acknowledge and agree to the
treatment of your Vested Options as described above, and as further specified in the Merger Agreement. Copies of the Merger Agreement are on file with Gerry Pesavento at the Company and are available for your review upon request should you desire to
understand in greater detail the specific terms and conditions that apply, in particular to Indemnity Holdback Amount and Expense Holdback Amount, under the Merger Agreement. 

If You Wish to Exercise Your Vested Company Options Prior to the Effective Time 

You may also choose to exercise your Vested Options prior to the Effective Time. If you wish to so exercise, please contact Gerry Pesavento at
the Company no later than August 22, 2013. No exercises of Company Options will be permitted after August 22, 2013. To exercise, you must provide a completed exercise notice to the Company and pay the aggregate
exercise price (including any applicable withholding taxes) applicable to the Vested Options you are exercising by the above date. As a stockholder of the Company at the Effective Time, a portion of the Merger consideration that you receive for your
shares will be held back as described above. 
 Exercising Incentive Stock Options: If you exercise Vested Options that qualify as
“incentive stock options” (“Vested ISOs”) under federal tax law, the aggregate amount of the Per Share Amount payable for the underlying shares minus the aggregate exercise price applicable to those shares (such
difference, the “Vested Spread”) will be reported as ordinary income to you for U.S. federal income tax purposes. The amount of Vested Spread reported to you as ordinary income will include the amount payable with respect to your
Vested Options that are held back as part of the Indemnity Holdback Amount or Expense Holdback Amount. None of the Vested Spread reported to you as ordinary income in connection with your exercise of Vested ISOs will be subject to income or
employment tax withholdings under applicable U.S. federal tax law. Please note that you should consider consulting your own tax adviser to understand the amount of employment taxes that will otherwise apply if you choose not to exercise your Vested
ISOs. 
 Exercising Nonstatutory Stock Options: If you exercise Vested Options that do not qualify as incentive stock options and are
considered to be “nonstatutory stock options” (“Vested NSOs”), the Vested Spread will be reported to you as ordinary income. The amount of Vested Spread reported to you as ordinary income will include the amount payable
with respect to your Vested NSOs that are held back as part of the Indemnity Holdback Amount and Expense Holdback Amount, and the full amount so reported will be subject to all applicable income and employment tax withholdings.  

Please note that, if your Vested Options remain outstanding at the Effective Time and you have signed and returned this Notice and Acknowledgement where
indicated below, they will automatically be cancelled and converted into the right to receive the cash amounts described above. EXCEPT AS NOTED IN THE NEXT PARAGRAPH, YOU DO NOT NEED TO EXERCISE YOUR VESTED OPTIONS IN ORDER TO RECEIVE THE CASH
AMOUNTS DESCRIBED ABOVE. 

  
 3 

 However, if your Vested Options will expire prior to the Effective Time or you otherwise want to exercise your
Vested Options prior to the Effective Time, please contact Gerry Pesavento by phone or via email as soon as possible to make the appropriate arrangements. The Company will not process option exercises after August 22, 2013. 

Unvested Company Options 
 Parent will assume all
Company Options that are outstanding and unvested as of the Effective Time and are held by a Continuing Employee (each, an “Assumed Option”). A “Continuing Employee” is someone who is an employee of the Company who
continues as an employee of Parent or its subsidiaries immediately following the Effective Time. Each Assumed Option will become an option to purchase a number of shares of Parent common stock equal to the product (rounded down to the next whole
number of shares of Parent common stock) of (A) the number of shares of Company common stock that would have been issuable upon exercise of the unvested Company Options immediately prior to the Effective Time and (B) the Equity Exchange
Ratio. Each Assumed Option will have a per share exercise price for the shares of Parent common stock payable upon exercise of the Assumed Option equal to the quotient (rounded up to the nearest whole cent) obtained by dividing the exercise price
per share of Company common stock at which such unvested Company Options was exercisable immediately prior to the Effective Time by the Equity Exchange Ratio. For these purposes, the “Equity Exchange Ratio” is defined in the Merger
Agreement and is calculated by dividing the Per Share Amount by the average per share closing trading price for Parent’s common stock for the twenty consecutive trading days ending on the date that was two trading days prior to the closing date
of the Merger. 
 Please note that any Assumed Options will otherwise continue to have and be subject to the same terms and conditions
(including if applicable the vesting arrangements and other terms set forth in the Plan and applicable option agreement) as are in place immediately prior to the Effective Time, except that the Assumed Options will be administered by Parent, will
not have an “early exercise feature” (meaning you would no longer be able to exercise to purchase unvested shares) and will be treated for tax purposes as nonstatutory stock options (and will be taxed upon exercise as described above for
Vested NSOs). In addition, if the terms of your Assumed Option include any rights to accelerated vesting of the option in connection with a termination of your employment after the Effective Time, you hereby agree to waive your rights to any such
accelerated vesting as a condition to Parent’s assumption of your option. 
 Parent will not assume any Company Options that are
outstanding and unvested as of the Effective Time and are held by a Non-Continuing Employee. A “Non-Continuing Employee” includes anyone who will not remain employed by Parent or its subsidiaries after the Effective Time, as well as
all consultants and independent contractors of the Company, even if they continue to provide services to Parent or its subsidiaries after the Effective Time. Unvested Company Options held by Non-Continuing Employees will be cancelled at the
Effective Time without consideration pursuant to the terms of the Plan.
