This Option shall be exercisable, in whole or in part, according to the following vesting schedule: 

[Twenty-five percent (25%) of the Shares subject to the Option shall vest on the one (1) year anniversary of the Vesting
Commencement Date, and one forty-eighth (1/48th) of the Shares subject to the Option shall vest each month thereafter][ One forty-eighth
(1/48th) of the Shares subject to the Option shall vest each month] on the same day of the month as the Vesting Commencement Date (and if there is no corresponding day, on the last day of the
month), subject to Participant continuing to be a Service Provider through each such date. 

 Termination Period: 

This Option shall be exercisable for three (3) months after Participant ceases to be a Service Provider, unless such termination is due

after the Term/Expiration Date as provided above and this Option may be subject to earlier termination as provided in Section 13(c) of the Plan. 
  

	II.	AGREEMENT 

 1. Grant of Option. The Administrator of the Company hereby
grants to the Participant named in the Notice of Stock Option Grant in Part I of this Agreement (“Participant”), an option (the “Option”) to purchase the number of Shares set forth in the Notice of Stock Option Grant, at the
exercise price per Share set forth in the Notice of Stock Option Grant (the “Exercise Price”), and subject to the terms and conditions of the Plan, which is incorporated herein by reference. Subject to Section 18(c) of the Plan, in
the event of a conflict between the terms and conditions of the Plan and this Option Agreement, the terms and conditions of the Plan shall prevail. 

If designated in the Notice of Stock Option Grant as an Incentive Stock Option (“ISO”), this Option is intended to qualify as an
Incentive Stock Option as defined in Section 422 of the Code. Nevertheless, to the extent that it exceeds the $100,000 rule of Code Section 422(d), this Option shall be treated as a Nonstatutory Stock Option (“NSO”). Further, if
for any reason this Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event shall the Administrator, the
Company or any Parent or Subsidiary or any of their respective employees or directors have any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 

2. Exercise of Option. 

(a) Right to Exercise. This Option shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice
of Stock Option Grant and with the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise. This
Option shall be exercisable by delivery of an exercise notice in the form attached as Exhibit A (the “Exercise Notice”) or in a manner and pursuant to such procedures as the Administrator may determine, which shall state the
election to exercise the Option, the number of Shares with respect to which the Option is being exercised, and such other representations and agreements as may be required by the Company. The Exercise Notice shall be accompanied by payment of the
aggregate Exercise Price as to all Exercised Shares, together with any applicable tax withholding. This Option shall be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise
Price, together with any applicable tax withholding. 

 No Shares shall be issued pursuant to the exercise of an Option unless such issuance and such
exercise comply with Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Participant on the date on which the Option is exercised with respect to such Shares. 

3. Participant’s Representations. In the event the Shares have not been registered under the Securities Act of 1933, as amended,
at the time this Option is exercised, Participant shall, if required by the Company, concurrently with the exercise of all or any portion of this Option, deliver to the Company his or her Investment Representation Statement in the form attached
hereto as Exhibit B. 
 4. Lock-Up Period. Participant hereby agrees that Participant shall not offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Stock (or other
securities) of the Company or enter into any swap, hedging or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) of the Company held by
Participant (other than those included in the registration) for a period specified by the representative of the underwriters of Common Stock (or other securities) of the Company not to exceed one hundred and eighty (180) days following the
effective date of any registration statement of the Company filed under the Securities Act (or such other period as may be requested by the Company or the underwriters to accommodate regulatory restrictions on (i) the publication or other
distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments
thereto). 
 Participant agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the
underwriter which are consistent with the foregoing or which are necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company,
Participant shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a
registration statement filed under the Securities Act. The obligations described in this Section 4 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in
the future, or a registration relating solely to a Commission Rule 145 transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or
other securities) subject to the foregoing restriction until the end of said one hundred and eighty (180) day (or other) period. Participant agrees that any transferee of the Option or shares acquired pursuant to the Option shall be bound by
this Section 4. 
 5. Method of Payment. Payment of the aggregate Exercise Price shall be by any of the following, or a
combination thereof, at the election of the Participant: 
 (a) cash; 

(b) check; 

 (c) consideration received by the Company under a formal cashless exercise program adopted by the
Company in connection with the Plan; or 
 (d) surrender of other Shares which (i) shall be valued at its Fair Market Value on the date
of exercise, and (ii) must be owned free and clear of any liens, claims, encumbrances or security interests, if accepting such Shares, in the sole discretion of the Administrator, shall not result in any adverse accounting consequences to the
Company. 
 6. Restrictions on Exercise. This Option may not be exercised until such time as the Plan has been approved by the
stockholders 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 Law. 

7. Non-Transferability of Option. 

(a) 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 Participant only by Participant. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of Participant. 

(b) Further, until the Company becomes subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, or after the
Administrator determines that it is, will, or may no longer be relying upon the exemption from registration of Options under the Exchange Act as set forth in Rule 12h-1(f) promulgated under the Exchange Act (the “Reliance End Date”),
Participant shall not transfer this Option or, prior to exercise, the Shares subject to this Option, in any manner other than (i) to persons who are “family members” (as defined in Rule 701(c)(3) of the Securities Act of 1933, as
amended) through gifts or domestic relations orders, or (ii) to an executor or guardian of Participant upon the death or disability of Participant. Until the Reliance End Date, the Options and, prior to exercise, the Shares subject to this
Option, may not be pledged, hypothecated or otherwise transferred or disposed of, including by entering into any short position, any “put equivalent position” or any “call equivalent position” (as defined in Rule 16a-1(h) and
Rule 16a-1(b) of the Exchange Act, respectively), other than as permitted in clauses (i) and (ii) of this paragraph. 
 8. Term
of Option. This Option may be exercised only within the term set out in the Notice of Stock Option Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. 

 9. Tax Obligations. 

(a) Tax Withholding. Participant agrees to make appropriate arrangements with the Company (or the Parent or Subsidiary employing or
retaining Participant) for the satisfaction of all Federal, state, local and foreign income and employment tax withholding requirements applicable to the Option exercise. Participant acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver the Shares if such withholding amounts are not delivered at the time of exercise. 
 (b) Notice of
Disqualifying Disposition of ISO Shares. If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two
(2) years after the Date of Grant, or (ii) the date one (1) year after the date of exercise, Participant shall immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income
tax withholding by the Company on the compensation income recognized by Participant. 
 (c) Code Section 409A. Under Code
Section 409A, an Option that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per Share exercise price that is determined by the
Internal Revenue Service (the “IRS”) to be less than the Fair Market Value of a Share on the date of grant (a “discount option”) may be considered “deferred compensation.” An Option that is a “discount option”
may result in (i) income recognition by Participant prior to the exercise of the Option, (ii) an additional twenty percent (20%) federal income tax, and (iii) potential penalty and interest charges. The “discount
option” may also result in additional state income, penalty and interest tax to the Participant. Participant acknowledges that the Company cannot and has not guaranteed that the IRS will agree that the per Share exercise price of this Option
equals or exceeds the Fair Market Value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was granted with a per Share exercise price that was less than the Fair Market Value of a
Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 
 10.
Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan and this Option Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all
prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. This
Agreement is governed by the internal substantive laws but not the choice of law rules of California. 
 11. No Guarantee of Continued
Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING
PARTICIPANT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH
HEREIN DO 

 
NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE IN ANY WAY WITH
PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE PARENT OR SUBSIDIARY EMPLOYING OR RETAINING PARTICIPANT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE. 

Participant acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms and provisions thereof, and
hereby accepts this Option subject to all of the terms and provisions thereof. Participant has reviewed the Plan and this Option in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Option and fully
understands all provisions of the Option. Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan or this Option. Participant further agrees
to notify the Company upon any change in the residence address indicated below.

2009 EQUITY INCENTIVE PLAN 

EXERCISE NOTICE 
 Lexity, Inc. 

1625 Pala Ranch Circle 
 San Jose, CA 95133 

Attention: Secretary 
 1. Exercise of
Option. Effective as of today,                     ,     , the undersigned (“Participant”) hereby elects to
exercise Participant’s option (the “Option”) to purchase                  shares of the Common Stock (the “Shares”) of Lexity, Inc. (the
“Company”) under and pursuant to the 2009 Equity Incentive Plan (the “Plan”) and the Stock Option Agreement dated
                    ,      (the “Option Agreement”). 

2. Delivery of Payment. Participant herewith delivers to the Company the full purchase price of the Shares, as set forth in the Option
Agreement, and any and all withholding taxes due in connection with the exercise of the Option. 
 3. Representations of Participant.
Participant acknowledges that Participant has received, read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. 

4. Rights as Stockholder. Until the issuance of the Shares (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Common Stock subject to an Award, notwithstanding the exercise of the Option. The Shares shall
be issued to Participant as soon as practicable after the Option is exercised in accordance with the Option Agreement. No adjustment shall be made for a dividend or other right for which the record date is prior to the date of issuance except as
provided in Section 13 of the Plan. 
 5. Company’s Right of First Refusal. Before any Shares held by Participant or any
transferee (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 5 (the “Right of First Refusal”). 
 (a) 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 bona fide cash price or other consideration for which the Holder proposes to
transfer the Shares (the “Offered Price”), and the Holder shall offer the Shares at the Offered Price to the Company or its assignee(s). 

 (b) 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 determined in accordance with subsection (c) below. 
 (c) Purchase Price. The purchase price (“Purchase
Price”) for the Shares purchased by the Company or its assignee(s) under this Section 5 shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall
be determined by the Board of Directors of the Company in good faith. 
 (d) Payment. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or, in the case of repurchase by an assignee, to the assignee), or by any combination
thereof within thirty (30) days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (e)
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 5, then the Holder may sell
or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other transfer is consummated within one hundred and twenty (120) days after the date of the Notice, that
any such sale or other transfer is effected in accordance with any applicable securities laws and that the Proposed Transferee agrees in writing that the provisions of this Section 5 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, 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. 
 (f) Exception for Certain Family Transfers.
Anything to the contrary contained in this Section 5 notwithstanding, the transfer of any or all of the Shares during the Participant’s lifetime or on the Participant’s death by will or intestacy to the Participant’s immediate
family or a trust for the benefit of the Participant’s immediate family shall be exempt from the provisions of this Section 5. “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 5, and there shall be no further transfer of such Shares except in accordance with the
terms of this Section 5. 
 (g) Termination of Right of First Refusal. The Right of First Refusal shall terminate as to any
Shares upon the earlier of (i) the first sale of Common Stock of the Company to the general public, or (ii) a Change in Control in which the successor corporation has equity securities that are publicly traded. 

 6. Tax Consultation. Participant understands that Participant may suffer adverse tax
consequences as a result of Participant’s purchase or disposition of the Shares. Participant represents that Participant has consulted with any tax consultants Participant deems advisable in connection with the purchase or disposition of the
Shares and that Participant is not relying on the Company for any tax advice. 
 7. Restrictive Legends and Stop-Transfer Orders.

 (a) Legends. Participant understands and agrees that the Company shall cause the legends set forth below or legends substantially
equivalent thereto, to be placed upon any certificate(s) evidencing ownership of the Shares together with any other legends that may be required by the Company or by state or federal securities laws: 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD
OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
THEREWITH. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY
THE ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN THE EXERCISE NOTICE BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER RESTRICTIONS AND RIGHT OF FIRST
REFUSAL ARE BINDING ON TRANSFEREES OF THESE SHARES. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER FOR
A PERIOD OF TIME FOLLOWING THE EFFECTIVE DATE OF THE UNDERWRITTEN PUBLIC OFFERING OF THE COMPANY’S SECURITIES SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF BY
THE HOLDER PRIOR TO THE EXPIRATION OF SUCH PERIOD WITHOUT THE CONSENT OF THE COMPANY OR THE MANAGING UNDERWRITER. 
 (b) Stop-Transfer
Notices. Participant 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 Exercise Notice 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. 

 8. Successors and Assigns. The Company may assign any of its rights under this Exercise
Notice to single or multiple assignees, and this Exercise Notice shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Exercise Notice shall be binding upon
Participant and his or her heirs, executors, administrators, successors and assigns. 
 9. Interpretation. Any dispute regarding the
interpretation of this Exercise Notice shall be submitted by Participant or by the Company forthwith to the Administrator, which shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator shall be
final and binding on all parties. 
 10. Governing Law; Severability. This Exercise Notice is governed by the internal substantive
laws, but not the choice of law rules, of California. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Exercise Notice shall continue in full force and
effect. 
 11. Entire Agreement. The Plan and Option Agreement are incorporated herein by reference. This Exercise Notice, the Plan,
the Option Agreement and the Investment Representation Statement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and
Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant.

	SECURITY	  	:	 	COMMON STOCK
			
	AMOUNT	  	:	 	
			
	DATE	  	:	 	

 In connection with the purchase of the above-listed Securities, the undersigned Participant represents to the
Company the following: 
 (a) Participant 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 Securities. Participant is acquiring these Securities for investment for Participant’s 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 of 1933, as amended (the “Securities Act”). 

(b) Participant acknowledges and understands that the Securities constitute “restricted securities” under the Securities Act and
have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Participant’s investment intent as expressed herein. In this
connection, Participant understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Participant’s representation was predicated solely upon a present intention to hold
these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market price of the Securities, or for a period of one (1) year or any other fixed period in
the future. Participant further 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. Participant further acknowledges and
understands that the Company is under no obligation to register the Securities. Participant understands that the certificate evidencing the Securities shall be imprinted with any legend required under applicable state securities laws. 

(c) Participant is familiar with the provisions of Rule 701 and Rule 144, each promulgated under the Securities Act, which, in
substance, permit limited public resale of “restricted securities” acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule 701 provides that if the
issuer qualifies under Rule 701 at the time of the grant of the Option to Participant, the exercise shall be exempt from registration under the Securities Act. In the event the Company becomes subject to the reporting requirements

 
of Section 13 or 15(d) of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of the applicable conditions specified by Rule 144, including in the case of affiliates (1) the availability of certain public information about the Company, (2) the
amount of Securities being sold during any three (3) month period not exceeding specified limitations, (3) the resale being made in an unsolicited “broker’s transaction”, transactions directly with a “market maker”
or “riskless principal transactions” (as those terms are defined under the Securities Exchange Act of 1934) and (4) the timely filing of a Form 144, if applicable. 

In the event that the Company does not qualify under Rule 701 at the time of grant of the Option, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which may require (i) the availability of current public information about the Company; (ii) the resale to occur more than a specified period after the purchase and
full payment (within the meaning of Rule 144) for the Securities; and (iii) in the case of the sale of Securities by an affiliate, the satisfaction of the conditions set forth in sections (2), (3) and (4) of the paragraph
immediately above. 
 (d) Participant further understands that in the event all of the applicable requirements of Rule 701 or 144 are
not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption shall 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 Rules 144 or 701 shall 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. Participant understands that no assurances can
be given that any such other registration exemption shall be available in such event.

 Exhibit 4.3 

LEXITY, INC. 
 OPTION
HOLDER NOTICE AND ACKNOWLEDGEMENT 
 As you know, Lexity, Inc. (the “Company”) has entered into an Agreement and Plan of Merger with
Yahoo! Inc. (“Parent”) and certain other parties thereto, dated July 27, 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 on or around July 31, 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 2009 Equity Incentive Plan, as has been in effect from time to time (the “Plan”). Please read this Option Holder Notice and Acknowledgment (the “Notice”) carefully. Additionally, and in order to
timely process and deliver any 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 to the Company by
July 29, 2013. 
 General Background on the Merger Consideration and Indemnification Obligations 

Based on an estimated closing date of July 31, 2013, holders of Company common stock will receive approximately $0.71 per share in consideration for their
shares in the Merger (the “Per Share Common 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 Common Amount 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 placed in escrow 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. 

 Treatment of Company Options 

Vested Company Options 
 If You
Do Not Wish to Exercise Your Vested Company Options Prior to the Effective Time 
 Parent will not assume any Company Options that are vested as of the
Effective Time (including any Company Options that become vested as a result of vesting acceleration immediately prior to 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 a cash payment equal to the product of (x) the number of shares of Company common stock issuable upon the exercise of such Vested Option immediately
prior to the Effective Time multiplied by (y) an amount equal to (1) the Per Share Common Amount minus (2) the per share exercise price for the shares of Company common stock that would have been issuable upon exercise of such
Vested Option immediately prior to the Effective Time, to be paid as promptly as practicable after the Effective Time, less all applicable withholding taxes. 

No payment shall be made with respect to any Option (whether vested or unvested) with a per share exercise price that equals or exceeds the amount of the Per
Share Common Amount. 
 You may be requested to complete a letter of transmittal and other exchange documentation 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. For U.S. taxpayers, please note that payments received in exchange for the cancellation of Vested Options constitute ordinary income
(in the case of employees 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, you understand, acknowledge and agree to the treatment of your Vested Options as described above, and as further
specified in the Merger Agreement. A copy of the Merger Agreement is on file with Amit Kumar at the Company and is available for your review upon request should you desire to understand in greater detail the specific terms and conditions that apply
under the Merger Agreement. 
 If You Wish to Exercise Your Vested Company Options Prior to the Effective Time 

Unless you have previously agreed not to exercise your Vested Options, you may also choose to exercise your Vested Options prior to the
Effective Time. If you wish to so exercise, please contact Amit Kumar at the Company no later than July 29, 2013. No exercises of Company Options will be permitted after July 29, 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 in escrow as noted 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 Common 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 

  
 2 

 
reported to you as ordinary income will include the amount payable with respect to your Vested Options that are held back as Escrow Amounts. 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 Escrow Amounts, 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. 
 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 Amit Kumar by phone or via email as soon as possible to make the appropriate arrangements. The Company will not process option exercises after July 29,
2013. 
 Unvested Company Options 
 Parent
will assume all of your Company Options that are outstanding and unvested as of the Effective Time if you are 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 the Company (or Parent or one of its other 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 (as defined in the Merger Agreement). 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.

 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 applicable 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). 
 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 the Company, Parent or one of its other 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. Pursuant to the terms of the Plan, Company Options that are not assumed will fully vest contingent on the
completion of the Merger and will be treated as discussed above under “Vested Company Options”. If you wish to exercise such Company Options prior to the completion of the Merger, please see “If You Wish to Exercise
Your Vested Company Options Prior to the Effective Time” above. Company Options held by Non-Continuing Employees that remain outstanding at the Effective Time will be treated as discussed above under “If You Do Not Wish to Exercise
Your Vested Company Options Prior to the Effective Time”. 
 The tax information in this Notice is summary information only and is given for
your reference. You agree that the Company and its affiliates and successors are not providing and have not provided you with any tax or financial advice with respect to these matters and that you are relying solely on your own tax and other
advisers in making any decisions regarding your Company Options. We encourage you to timely consult your own tax and financial advisers on these matters. 

* * * 
 Please indicate your acceptance of the
terms and conditions described above by signing and returning this Notice to Amit Kumar no later than the close of business on July 29, 2013. It is important that you take this action to receive payments related to your Vested Options and
receive Assumed Options with respect to your unvested Company Options. If you do not timely sign and return this Notice, your unvested Company Options will not be assumed by Parent and will instead be cancelled at the Effective Time in exchange for
the cash payment discussed above. You will not have any further rights with respect to or in respect of any Company Options that are so cancelled.
