Form of Option Exercise and Repurchase Agreements

 Exhibit 10.10 
 LINKEDIN CORPORATION 
 OPTION EXERCISE AND REPURCHASE AGREEMENT

 This OPTION EXERCISE AND REPURCHASE AGREEMENT (this “Agreement”) is made and entered into as of
[            ], 20[    ] (the “Effective Date”), by and between LinkedIn Corporation, a Delaware corporation (the
“Company”), and [            ], an executive of the Company (the “Purchaser”). Capitalized terms not defined herein shall have the meanings ascribed
to them in the Company’s Amended and Restated 2003 Stock Incentive Plan, as may be further amended and/or restated from time to time (the “Plan”). 
 RECITALS 
 A.        Pursuant to
the Plan, the Company has granted to the Purchaser an option (“Option”) to purchase [            ] shares of common stock of the Company (the
“Option Shares”). Such Option is exercisable at the Exercise Price Per Share specified in the Notice of Stock Option Grant entered into between the Company and the Purchaser and dated as of
[            ] (the “Notice of Grant”) and setting forth the terms and conditions of the Option. 

B.        As of the Effective Date, none of the Option Shares are vested (“Vested
Shares”) and all of the Option Shares are unvested (“Unvested Shares”) in accordance with the Vesting Schedule set forth in the Notice of Grant. 

C.        The Purchaser desires to exercise the Option to purchase
[            ] shares (the “Shares”), consisting of [            ] Unvested Shares and no
Vested Shares, for an aggregate purchase price of $[            ] (the “Purchase Price”), payable to the Company by delivery of certain promissory notes as
set forth herein. 
 D.        The Company is willing to permit Purchaser to exercise
the Option on the terms set forth herein, under an Executive Loan Program approved by the Company’s Board of Directors (“the “Loan Program”). Under the Loan Program, certain executives of the Company have been
offered the right to exercise options to purchase Common Stock of the Company granted to them under the Plan by executing promissory notes payable to the Company in an aggregate amount not to exceed $750,000 principal amount per participating
executive. Of the total principal amount of the notes, 55% will be evidenced by a full recourse promissory note and 45% will be evidenced by a non-recourse promissory note. Both notes will be secured by the shares of Common Stock so purchased, will
be due as set forth in such notes (including provisions for the acceleration of the due date upon the occurrence of various events, such as termination of employment under certain circumstances or the Company filing a registration statement under
the Securities Act of 1933). In order to ensure compliance with provisions of the federal securities laws prohibiting companies from extending or maintaining credit to certain executives, the Loan Program also contemplates that the Company will have
the right to repurchase some or all of the shares so purchased by cancellation of the notes in advance of filing such a registration statement. The price at which the Company will have the right to repurchase the shares will be the fair market value
of the Company’s Common Stock, as 

 
determined by the Board of Directors of the Company at a time prior to the Company’s filing of a registration statement. Purchaser shall have no say in the Board’s establishment of the
repurchase price and Purchaser specifically acknowledges that such repurchase price may be lower or higher than the price per share Purchaser paid to exercise his or her option or lower or higher than the price per share in the Company’s
initial public offering, if any. Each participating employee will receive advance notice of the Company’s intent to exercise its right to repurchase shares, in order to make arrangements to pay the amounts outstanding on the notes. 

E.           These recitals are included for informative purposes only, and shall
not be deemed to modify or change any provision of this Agreement. If there is any conflict between the descriptions set forth in these recitals and any other provision of this Agreement, such other provision shall control. 

AGREEMENT 

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows: 
 1.           VESTING OF
SHARES.  For purposes of determining vesting of the Unvested Shares under this Agreement, all Unvested Shares shall continue to vest in accordance with the Vesting Schedules set forth in the Notice of Grant and become Vested Shares at
the time of such vesting. For purposes of determining the order of vesting of the Unvested Shares purchased hereunder and the vesting of any remaining Unvested Shares as to which the Option is not being exercised, all Unvested Shares purchased
hereunder shall vest before any Unvested Shares remaining under the Notice of Grant shall vest. 

2.           CLOSING. 

2.1        Deliveries by the Purchaser.  The Purchaser hereby delivers to the
Company: (i) the Purchase Price payable by two Secured Promissory Notes, one of which is a full recourse promissory note in the form of Exhibit 1 attached hereto for the principal amount of
$[            ] (the “Full Recourse Note”) and the second of which is a non-recourse promissory note in the form of Exhibit 2 attached hereto for
the principal amount of $[            ] (the “Non-Recourse Note” and, together with the Full Recourse Note, the “Notes”), attached
hereto; (ii) a duly executed copy of this Agreement; (iii) three (3) copies of a blank Stock Power and Assignment Separate from Stock Certificate in the form of Exhibit 3 attached hereto (the “Stock
Powers”), both executed by the Purchaser (and the Purchaser’s spouse or domestic partner, if any); and (iv) if the Purchaser is married or has a domestic partner, a Spouse/Domestic Partner Consent in the form of
Exhibit 4 attached hereto (the “Spouse/Domestic Partner Consent”) duly executed by the Purchaser’s spouse or domestic partner. 
 2.2        Deliveries by the Company.  Upon its receipt of all the documents to be executed and delivered by the Purchaser to the Company under
Section 2.1, the Company will issue a duly executed stock certificate evidencing the Shares in the name of the Purchaser, registered in the Purchaser’s name, with such certificate to be pledged to, and held by, the Company as provided in
Section 8 until (i) expiration or termination of the Repurchase Option described in Section 4, the 

  
 -2-

 
First Refusal Right described in Section 5 and the Call Option Right described in Section 6 and (ii) full payment of the Notes. 

3.           REPRESENTATIONS AND WARRANTIES OF THE
PURCHASER.  The Purchaser represents and warrants to the Company that: 

3.1        Securities for Own Account for Investment.  The Purchaser is
purchasing the Shares for the Purchaser’s own account for investment purposes only and not with a view to, or for sale in connection with, a distribution of the Shares within the meaning of the U.S. Securities Act of 1933, as amended (the
“Securities Act”). The Purchaser has no present intention of selling or otherwise disposing of all or any portion of the Shares and no one other than the Purchaser has any beneficial ownership of any of the Shares.

 3.2        Access to Information.  The Purchaser has had access to
all information regarding the Company and its present and prospective business, assets, liabilities and financial condition that the Purchaser reasonably considers important in making the decision to accept the Shares, and the Purchaser has had
ample opportunity to ask questions of the Company’s representatives concerning such matters and this investment. 

3.3        Understanding of Risks.  The Purchaser is fully aware of:
(i) the highly speculative nature of the investment in the Shares; (ii) the financial hazards involved; (iii) the lack of liquidity of the Shares and the restrictions on transferability of the Shares (e.g., that the Purchaser may not
be able to sell or dispose of the Shares or use them as collateral for loans); (iv) the qualifications and backgrounds of the management of the Company; and (v) the tax consequences (known or unknown) of accepting and holding the Shares,
including potential changes to tax laws that may be enacted (and which could be effective retroactively). 

3.4        Compliance with Securities Laws.  The Purchaser understands and
acknowledges that, in reliance upon the representations and warranties made by the Purchaser herein, the Shares are not being registered with the U.S. Securities and Exchange Commission (“SEC”) under the Securities Act or
being qualified under the California Corporate Securities Law of 1968, as amended (the “Law”), or being registered under any other applicable U.S. state or foreign securities laws or listing requirements or regulations, but
instead are being issued under an exemption or exemptions from the registration and qualification requirements of the Securities Act and the Law, which impose certain restrictions on the Purchaser’s ability to transfer the Shares. 

3.5        Restrictions on Transfer.  The Purchaser understands that the
Purchaser may not transfer any Shares unless such Shares are (i) registered under the Securities Act and qualified under the Law and/or such other applicable U.S. state securities law, (ii) registered under such other applicable foreign
securities laws or listing requirements or regulations or (iii) in the opinion of counsel to the Company, exemptions from such registration, qualification or listing requirements are available. 

4.           COMPANY’S REPURCHASE OPTION FOR UNVESTED SHARES.

  
 -3-

 4.1        Repurchase Option.  The
Company, or its assignee, shall have the option to repurchase all or any portion of the Unvested Shares on the terms and conditions set forth in this Section 4 (the “Repurchase Option”) if the Purchaser is Terminated (as
defined in Section 4.3 hereunder). 
 4.2        Release of Unvested Shares
from Repurchase Option.  As Unvested Shares become Vested Shares in accordance with the Vesting Schedules set forth in the Notice of Grant and in accordance with Section 1, such Shares shall be released from the Repurchase Option
(but the certificates for such Shares shall continue to be held by the Company until all the conditions in Section 2.2 have been satisfied). 
 4.3        Definitions.  For the purpose of this Agreement, the following terms shall have the meaning indicated below: 

“Cause” shall mean the Purchaser being convicted of, or entering a plea of nolo contendere to, any felony or a
misdemeanor involving an act of moral turpitude, dishonesty or fraud; 
 “Change of Control” shall mean
(A) the closing of the sale, transfer or other disposition of all or substantially all of the Company’s assets, (B) the consummation of a merger, reorganization, consolidation or share transfer which results in the voting securities
of the Company outstanding immediately prior thereto or the voting securities issued with respect to the voting securities of the Company outstanding immediately prior thereto representing immediately thereafter less than a majority of the combined
voting power of the voting securities of the Company or the surviving or acquiring entity outstanding immediately after such merger, reorganization, consolidation or share transfer or (C) the closing of the transfer (whether by merger,
consolidation or otherwise), in one transaction or a series of related transactions, to a person or group of affiliated person (other than an underwriter of the Company’s securities), of the Company’s securities if, after such closing,
such person or group of affiliated persons would hold 50% or more of the outstanding voting stock of the Company (or the surviving or acquiring entity). 
 4.4        Termination and Termination Date.  For purposes of this Agreement, “Termination” or
“Terminated” means that the Purchaser’s Service with the Company or its Subsidiaries has terminated, including without limitation the Purchaser’s death, disability, voluntary resignation or termination by the
Company with or without Cause (as defined in section 4.3 of this Agreement). The date on which a Termination becomes effective is referred to herein as the “Termination Date.” The Purchaser will not be deemed to have been
Terminated while the Purchaser is on a bona fide leave of absence, to the extent required by applicable law or approved by the Administrator under the Plan. 
 4.5        Exercise of Repurchase Option.  At any time within 90 days after the Purchaser’s Termination Date, the Company, or its assignee,
may elect to repurchase all or any portion of the Unvested Shares by giving the Purchaser written notice of exercise of the Repurchase Option (the “Repurchase Notice”). The Repurchase Notice shall indicate the number of
Unvested Shares to be repurchased and the date on which the repurchase is to be effected (the “Repurchase Date”), such date to be not more than 30 days after the date of the Repurchase Notice. The

  
 -4-

 
certificates representing the Unvested Shares to be repurchased shall be delivered to the Company or its assignee on the closing date specified for the repurchase in the Repurchase Notice.

 4.6        Calculation of Repurchase Price for Unvested
Shares.  The Company or its assignee shall have the option to repurchase from the Purchaser (or from the Purchaser’s personal representative as the case may be) all or any portion of the Unvested Shares at an aggregate repurchase
price (the “Repurchase Price”) equal to the sum of (i) the Exercise Price Per Share applicable to such Unvested Shares multiplied by the number of Unvested Shares to be repurchased plus (ii) interest on such amount
from the Effective Date to the date of repurchase at the rate of [      ] % per annum, compounded annually. 
 4.7        Payment of Repurchase Price.  The Repurchase Price shall be payable by cancellation of all or a portion of any outstanding indebtedness
of the Purchaser to the Company if the Company repurchases the Unvested Shares. If the Company assigns the Repurchase Option, the assignee shall pay the Repurchase Price by cash or check. If, on the Repurchase Date, the Purchaser owes any money to
the Company (whether then due or not), the assignee shall pay the Repurchase Price to the Company, and the Company will apply such Repurchase Price against outstanding debt from the Purchaser. To the extent that any amounts remain unpaid on the
Notes on the Repurchase Date, any such cancellation of indebtedness, or payment of the Repurchase Price by an assignee to the Company, shall be applied first against the Notes, ratably between the outstanding balance of the Full Recourse Note and
the Non-Recourse Note. To the extent that the Repurchase Price exceeds the amount of all outstanding indebtedness of the Purchaser to the Company, such excess shall be paid by the Company or its assignee by check made payable to the Purchaser. The
Repurchase Price shall be paid on the Repurchase Date, upon the Company’s or its assignee’s receipt of the stock certificates representing the Unvested Shares to be repurchased. 

4.8        Right of Termination Unaffected.  Nothing in this Agreement shall be
construed to limit or otherwise affect or amend the at-will nature of Purchaser’s employment with the Company (or any Parent or Subsidiary of the Company), meaning that the Company or Purchaser can terminate Purchaser’s employment with the
Company (or any such Parent or Subsidiary) at any time, with or without notice, and for any reason or no reason, with or without Cause. 
 5.           COMPANY’S FIRST REFUSAL RIGHT.  The Shares held by the Purchaser or any transferee of such Shares (either being
referred to herein as the “Holder”) shall be subject to the First Refusal Right on the terms and conditions set forth in the Plan. 
 6.           COMPANY’S CALL OPTION RIGHT. 
 6.1        Call Option Right.  If at any time the Company determines to file a registration statement under the Securities Act of 1933, as amended,
with the SEC, the Company shall have the right (the “Call Option Right”) to purchase from Purchaser sufficient Vested Shares to completely retire all outstanding indebtedness from the Purchaser to the Company, whether
pursuant to the Notes or otherwise. To exercise the Call Option Right, the Company shall send to Purchaser written notice of its intent to file such a registration statement (the “Call Option Exercise Notice”), which notice
shall specify the number of Vested Shares to be purchased by the Company (including sufficient information on how the Company determined such number in accordance with 

  
 -5-

 
Section 6.2), the price at which such Vested Shares will be purchased and a statement as to the date on which the purchase will occur (the “Call Option Closing
Date”), which date shall be at least 31 days after the Call Option Exercise Notice is delivered to the Purchaser in accordance with Section 10.3 
 6.2         Determination of Shares Subject to Call Option.  The number of Vested Shares that the Company shall have the right to purchase from
Purchaser pursuant to the Call Option Right shall be determined by dividing (i) the aggregate amount of all outstanding indebtedness to the Company (which amount shall include all principal and accrued interest through the Call Option Closing
Date) by (ii) the Call Option Exercise Price. The “Call Option Exercise Price” shall be the Board’s good faith estimate of the fair market value of one share of the Company’s Common Stock as of the Call Option
Closing Date (which estimate shall be made not more than 45 days prior to the Call Option Closing Date). The Board may, but is not required to, include in its determination of the Call Option Exercise Price a mechanism by which such Call Option
Exercise Price will be adjusted (upward or downward) as of a later date (such as the effective time of the registration statement to be filed with the SEC or the pricing of the public offering covered by such registration statement), based upon such
adjustment mechanism as the Board may determine (which mechanism shall comply with all applicable laws and regulations, including Section 409A of the Internal Revenue Code). Upon any such adjustment of the Call Option Exercise Price,
(i) in the event of an upward adjustment, the Company shall pay the amount of such upward adjustment by check to Purchaser or (ii) in the event of a downward adjustment, the Company shall repurchase and cancel such number of additional
Vested Shares as is necessary to fully cancel all outstanding indebtedness of Purchaser to the Company as of the Call Option Closing Date based upon the adjusted Call Option Exercise Price. 

6.3         Effect of Payment of Outstanding Indebtedness.  At any time after
delivery of the Call Option Exercise Notice until one day prior to the Call Option Closing Date, Purchaser may pay off all or any portion of his or her outstanding indebtedness to the Company by cash or check, and the number of Vested Shares to be
purchased by the Company shall be reduced commensurately, so that the number of Vested Shares purchased at the Call Option Closing Date will be the minimum number required to completely retire all then outstanding indebtedness from the Purchaser to
the Company. 
 6.4         Closing.   On the Call Option Closing
Date, the Company will cancel the stock certificates representing the number of Vested Shares to be purchased by the Company to retire all outstanding indebtedness from the Purchaser to the Company, and issue a new certificate in the name of
Purchaser for the balance of the Shares not purchased. The Company will issue a new certificate and hold it until the expiration or termination of the Repurchase Option and the First Refusal Right, as set forth in Section 2.2. All outstanding
indebtedness from the Purchaser to the Company will be cancelled, and the Notes or other evidence of indebtedness will also be cancelled and delivered back to Purchaser by the Company. 

6.5         Assignment.   The Company may assign the Call Option Right to such
assignee as the Company chooses, in whole or in part. In the event of such an assignment, the purchase price for the Vested Shares to be purchased shall be paid directly to the Company, and the Company shall, upon receipt of such payment, cancel all
outstanding indebtedness from the 

  
 -6-

 
Purchaser to the Company (or, in the event of a partial assignment, an amount of such indebtedness equal to the amount of the purchase price paid by such assignee). 

6.6         Taxes.  Purchaser acknowledges that the purchase of Vested Shares
by the Company upon exercise of the Call Option Right may result in Purchaser recognizing taxable income, and that Purchaser is wholly responsible for paying taxes on any such taxable income. 

7.            RIGHTS AS STOCKHOLDER.  Subject to the terms and
conditions of this Agreement, the Purchaser will have all of the rights of a stockholder of the Company with respect to the Shares from and after the date that Shares are issued to the Purchaser until such time as the Purchaser disposes of the
Shares or the Company and/or its assignee(s) exercise(s) the Repurchase Option, the First Refusal Right or the Call Option Right. Upon an exercise of the Repurchase Option, the First Refusal Right or the Call Option Right, the Purchaser will have no
further rights as a holder of the Shares so purchased upon such exercise, except the right to receive payment for the Shares so purchased in accordance with the provisions of this Agreement, and the Purchaser will promptly surrender the stock
certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 

8.            SECURITY INTEREST AND PLEDGE.  As security for the
Purchaser’s faithful performance of this Agreement and to perfect the security interest in the Shares granted by Purchaser to the Company under the Notes, the Purchaser pledges the Shares to the Company and further agrees that the Company shall
hold the certificates representing the Shares, together with the pledged stock powers executed by the Purchaser and by the Purchaser’s spouse or domestic partner, if any (with the date and number of Shares left blank), to the Company. Purchaser
authorizes the Company to take all such actions and to effectuate all such transfers and/or releases of such Shares as are in accordance with the terms of this Agreement. 
 9.            TAX CONSEQUENCES. 
 9.1         Representations.  THE PURCHASER UNDERSTANDS THAT THE PURCHASER MAY SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF THE PURCHASER’S
PURCHASE OR DISPOSITION OF THE SHARES. THE PURCHASER REPRESENTS (I) THAT THE PURCHASER HAS BEEN ADVISED TO CONSULT WITH A TAX ADVISOR IN CONNECTION WITH THE PURCHASE OR DISPOSITION OF THE SHARES AND (II) THAT THE PURCHASER IS NOT RELYING ON THE
COMPANY, THE COMPANY’S COUNSEL OR ANY OFFICER, DIRECTOR, EMPLOYEE OR AGENT OF THE COMPANY FOR ANY TAX OR LEGAL ADVICE IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY. IN PARTICULAR, IF ANY SHARES ARE SUBJECT TO
REPURCHASE BY THE COMPANY, THE PURCHASER REPRESENTS THAT THE PURCHASER HAS CONSULTED WITH THE PURCHASER’S TAX ADVISOR CONCERNING THE ADVISABILITY OF FILING AN 83(B) ELECTION WITH THE INTERNAL REVENUE SERVICE. 

9.2         Section 83(b) Election for Unvested Shares.  Unless an
election is filed by the Purchaser with the Internal Revenue Service (and, if necessary, the proper state taxing authorities), within 30 days after the purchase of the Unvested Shares, electing pursuant to Section 83(b) of the

  
 -7-

 
Code (and similar state tax provisions, if applicable) to be taxed currently on any difference between the Exercise Price Per Share and the fair market value of the Common Stock on the Effective
Date, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to the Purchaser, measured by the excess, if any, of the fair market value of the Unvested Shares at the time they cease to be
Unvested Shares, over the Exercise Price Per Share. 
 10.         GENERAL
PROVISIONS. 
 10.1         Assignments: Successors and Assigns.
  The Company may assign any of its rights and obligations under this Agreement, including its rights to repurchase Shares under the Repurchase Right, the First Refusal Right and the Call Option Right; provided, that any such assignment
shall require approval of the Board. Any assignment of rights and obligations by any other party to this Agreement requires the Company’s prior written consent. This Agreement, and the rights and obligations of the parties hereunder, will be
binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives. 
 10.2         Governing Law; Severability.   This Agreement shall be governed by and construed in accordance with the internal laws of the State of
Delaware, without regard to principles of conflicts of laws. The Company and the Purchaser each hereby (i) submits to the exclusive jurisdiction of the Delaware Chancery Court for any action, suit or proceeding arising out of or relating to
this Agreement, (ii) agrees that no such action, suit or proceeding shall be brought by it except in such court, and (iii) irrevocably waives, and agrees not to assert (by way of motion, defense or otherwise), in any such action, suit or
proceeding, any claim that it is not subject personally to the jurisdiction of the Delaware Chancery Court, that its property is exempt or immune from attachment or execution, that such action, suit or proceeding is brought in an inconvenient forum,
that the venue of such action, suit or proceeding is improper or that this Agreement may not be enforced in or by the Delaware Chancery Court. 
 10.3         Notices.   Any notice required to be given to the Company shall be in writing and addressed to the Secretary of the Company at its
principal corporate offices. Any notice required to be given to the Purchaser shall be in writing and addressed to the Purchaser at the address indicated on the signature page to this Agreement or to such other address as the Purchaser may designate
in writing from time to time to the Company. All notices shall be deemed effectively given upon personal delivery, or one business day after its deposit with any return receipt express overnight courier (prepaid). 

10.4         Further Assurances.   The parties agree to execute such further
documents and instruments and to take such further actions as may be reasonably necessary to carry out the purposes and intent of this Agreement. 
 10.5         Titles and Headings.   The titles, captions and headings of this Agreement are included for ease of reference only and will be
disregarded in interpreting or construing this Agreement. Unless otherwise specifically stated, all references herein to “sections” and “exhibits” will mean “sections” and “exhibits” to this Agreement.

  
 -8-

 10.6     Counterparts.   This Agreement may be
executed in any number of counterparts, each of which when so executed and delivered will be deemed an original, and all of which together shall constitute one and the same agreement. 

10.7     Severability.   If any provision of this Agreement is determined by any court or
arbitrator of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced,
such provision shall be stricken from this Agreement and the remainder of this Agreement shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Agreement.
Notwithstanding the foregoing, if the value of this Agreement based upon the substantial benefit of the bargain for any party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be
binding, then both parties agree to substitute such provision(s) through good faith negotiations. 

10.8     Amendment and Waivers.   This Agreement may be amended only by a written agreement
executed by each of the parties hereto. No amendment of or waiver of, or modification of any obligation under this Agreement will be enforceable unless set forth in a writing signed by the party against which enforcement is sought. Any amendment
effected in accordance with this section will be binding upon all parties hereto and each of their respective successors and assigns. No delay or failure to require performance of any provision of this Agreement shall constitute a waiver of that
provision as to that or any other instance. No waiver granted under this Agreement as to anyone provision herein shall constitute a subsequent waiver of such provision or of any other provision herein, nor shall it constitute the waiver of any
performance other than the actual performance specifically waived. 
 10.9     Entire Agreement.
  This Agreement, the documents referred to herein, the Plan, the Notice of Grant and the Company’s Amended and Restated Stock Option Agreements, entered into between the Company and the Purchaser, constitute the entire agreement and
understanding of the parties with respect to the subject matter of this Agreement, and supersede all prior understandings and agreements, whether oral or written, between or among the parties hereto with respect to the specific subject matter
hereof.

	$[            ]	 	[            ], 20[    ]

FOR VALUE RECEIVED, the undersigned promises to pay to LinkedIn Corporation, a Delaware corporation (the
“Company”), or order, at its principal office, the principal amount of $[            ], plus accrued interest thereon, upon the earlier of (i) the
seventh anniversary of the date of this Note, (ii) the closing of a Change of Control in which the proceeds to the stockholders of the Company include cash or freely marketable securities, assuming such Change of Control is done with the
Company’s consent, (iii) 30 days following the Termination of the undersigned’s Service with the Company if such Termination is (A) by the Company for Cause or (B) voluntarily by the undersigned, unless the Board elects, in
its sole discretion, to have subsection (i) of this section apply to such voluntary Termination, (iv) the closing of any private sale of the Pledged Stock (as defined below), or (v) 30 days following the Company’s delivery of the
Call Option Exercise Notice in accordance with the Option Exercise Agreement (as defined below) (the “Due Date”). This Note shall bear interest at the rate per annum of
[        ]%, compounded annually. Payment of such interest shall be deferred until the Due Date, provided that the undersigned shall submit to the Company payment in full of all such interest on the Due
Date. For purposes of this Note and for clarification purposes, the undersigned’s death or disability shall not be deemed a Termination for Cause or a voluntary Termination by the undersigned. 

Capitalized terms not defined herein shall have the meanings ascribed to them in that certain Option Exercise and Repurchase Agreement
between the Company and the undersigned dated the same date as this Note (the “Option Exercise Agreement”) or in the Company’s Amended and Restated 2003 Stock Incentive Plan (the “Plan”).

 As security for the full and timely payment of this Note, the undersigned hereunder pledges and grants to the Company a
security interest in [            ] shares of the Company’s common stock exercised by the undersigned pursuant to the Option Exercise Agreement (the “Pledged
Stock”), together with any stock subscription rights, liquidating dividends, stock dividends, new securities of any type whatsoever, or any other property which the undersigned is or may be entitled to receive as a result of the
undersigned’s ownership of the Pledged Stock. The undersigned shall, upon execution of this Note, deliver (or authorize the Company to retain) all certificates representing the Pledged Stock to the Company. The Company shall hold the Pledged
Stock to perfect the security interest granted hereunder. 
 If the undersigned’s Service is Terminated and any shares of
the Pledged Stock are Unvested Shares and remain subject to the Repurchase Option, that portion of the principal amount of this Note (and any interest accrued thereon from the date hereof) equal to the number of Unvested Shares multiplied by the
Exercise Price Per Share shall become immediately due and payable. In such event, the Company may elect to repurchase such Unvested Shares from the undersigned by cancelling such portion of the principal amount of this Note (and any interest accrued
thereon) and extinguishing the undersigned’s payment obligations for such portion hereunder. 

 The undersigned may prepay any amount due hereunder at any time, without premium or penalty.

oral understanding to which Hoffman is a party or by which Hoffman is bound. 

(e)         Consents.   No consent, approval or authorization of any individual

The Company hereby represents and warrants to Hoffman as follows: 

(a)         Authority.   The Company is duly organized, validly existing, and
in good standing under the law of every jurisdiction in which it conducts business. All necessary actions have been taken to authorize the Company to execute this Agreement and perform the Company’s obligations hereunder. The Company’s
authorization, execution, delivery and performance of this Agreement do no conflict with or violate any law applicable to the Company or any other agreement or arrangement to which the Company is a party or by which the Company or its assets are
bound. 
 (b)         Investment.   The Company is acquiring the
Interests for the Company’s own account, not as a nominee or agent, for investment purposes only and not with a view to or for the resale or distribution thereof, and has no agreement or arrangement or plan of any kind with any person to sell,
transfer or pledge to any person any part of the Interests. 
 (c)        
Knowledge.   The Company has sufficient knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of its investment in Degrees LLC, is able to bear the economic risks of the
Company’s investment and participation in Degrees LLC, and is financially able to hold the Interests for an indefinite period of time and to suffer a complete loss of such investment. The Company has acquired all information it has requested

 -3-

 (d)         Restrictions on
Transfer.  The Company understands that the Interests have not been registered under the Securities Act of 1933, as amended or any state securities laws, and under such laws, may not be resold or transferred by the Company without
appropriate registration or the availability of an exemption from such requirements. 

5.            Acquisition of Six Degrees Patent.  If the Company,
directly or indirectly, acquires sole ownership of the Six Degrees Patent (whether by purchase of all other membership units of Degrees LLC or otherwise), then: 
 (i)         in the event the Company and/or its affiliates sell the Six Degrees Patent to any individual or entity (other than the Company or any of its affiliates)
as a discrete, stand alone asset sold separately from other assets or businesses of the Company and/or its affiliates, the Company shall, within thirty (30) days after receiving any cash payment arising from such sale, pay to Hoffman an amount
of cash equal to the product of (A) 0.80 and (B) (x) the aggregate sales price for the Six Degrees Patent in such sale, minus (y) the Purchase Price, minus (z) the aggregate amount paid or payable by the Company
and/or its affiliates to acquire sole ownership of the Six Degrees Patent (other than the Purchase Price); 

(ii)       in the event the Company and/or its affiliates sell the Six Degrees Patent to any individual or
entity (other than the Company or any of its affiliates) with other assets or businesses of the Company and/or its affiliates, otherwise than pursuant to a Change of Control Transaction (as defined below), (A) prior to such sale, the Company
and Hoffman shall mutually agree on the portion of the aggregate sales price in such sale that is attributable to only the Six Degrees Patent and (B) the Company shall, within thirty (30) days after receiving any cash payment arising from
such sale, pay to Hoffman an amount of cash equal to the product of (A) 0.80 and (B) (x) the portion of the aggregate sales price in such sale that the Company and Hoffman mutually agreed is attributable to only the Six Degrees Patent,
minus (y) the Purchase Price, minus (z) the aggregate amount paid or payable by the Company and/or its affiliates to acquire sole ownership of the Six Degrees Patent (other than the Purchase Price); and 

(iii)       in the event the Company and/or its affiliates grants any rights with respect to the Six
Degrees Patent to any individual or entity (other than the Company or any of its affiliates), otherwise than pursuant to a Change of Control Transaction (as defined below) or to the sale of the Six Degrees Patent, the Company shall, or shall cause
its applicable affiliates to, promptly thereafter grant such rights to Hoffman on terms no less favorable to Hoffman in the aggregate as the terms given to such other individual or entity with respect to such rights. 

The provisions contained in this Section 5 shall terminate and have no further force or effect upon the consummation of a Change of
Control Transaction. For purposes of this Agreement, the term “Change of Control Transaction” means the acquisition of the Company (whether by merger or otherwise) or the sale of all or substantially all of the assets of the
Company. 
 6.         Further Assurances.  Subsequent to the execution
and delivery of this Agreement and without any additional consideration, each party hereto, at the written request of the other party hereto, will execute and deliver any further legal instruments, and take all such other actions, which are or may
become reasonably necessary or helpful to effectuate the purposes of this Agreement.

 7.         Governing Law.   This
Agreement and the relationship between the parties hereto shall be governed by and construed and enforced in accordance with the laws of the State of California without regard to its principles of conflicts of law. 

8.         Entire Agreement.   This Agreement constitutes and contains the
entire agreement and understanding of the parties hereto with respect to the subject matter hereof and supersedes any and all prior and contemporaneous negotiations, correspondences, agreements, understandings, duties or obligations between the
parties respecting the subject matter hereof. 
 9.         Counterparts.
  This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or
otherwise) by facsimile or by electronic delivery in PDF format shall be sufficient to bind the parties to the terms and conditions of this Agreement. 
 10.       Severability.   In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto shall use their
reasonable best efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable
provision. 
 11.       Specific Performance.   The parties hereto hereby
acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each of the
parties hereto, in addition to any other available rights or remedies, shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United
States or any state having jurisdiction, and each party hereto hereby expressly waives the defense that a remedy in damages will be adequate. 
 12.       Assignment; Successors.   The rights and obligations of Hoffman under this Agreement may not be assigned or delegated, in whole or in part, by
operation of law or otherwise, without the prior written consent of the Company. Subject to the immediately preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their
respective successors and assigns. 
 13.       Amendment; Waiver.   No term or
provision of this Agreement may be amended or waived except in writing signed by the party against whom enforcement of such amendment or waiver is sought.
