Shares subject to the Award issued in book entry form that have vested or deliver to Participant a certificate or certificates evidencing the number of Shares subject to the Award that have vested in accordance with Joint Escrow Instructions set
forth on Exhibit E to the Grant Notice. Participant (or the beneficiary or personal representative of Participant in the event of Participant’s death or incapacity, as the case may be) shall deliver to the Company any representations or
other documents or assurances required by the Company. The Shares so delivered shall no longer be subject to the Restrictions hereunder. 
 2.2 Conditions.

avoidance of doubt, the Right of Repurchase shall only lapse as set forth in Section 2.2(c).

fully vested and the Restrictions thereupon shall lapse. For purposes of this Section 2.2(c), “Earned Shares” shall be the number of Shares equal to (x) the “Target Shares” (as defined in Exhibit B) before the

order with a broker with respect to Shares for which the Restrictions are then subject to lapse, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale
to the Company in satisfaction of its withholding obligations; provided, that payment of such proceeds is then made to the Company upon settlement of such sale). 
 (e) Conditions to Delivery of Shares. Subject to Section 2.1, the Shares deliverable under this Award may be either previously authorized but unissued Shares or issued Shares that have then
been reacquired by the Company. Such Shares shall be fully paid and nonassessable. The Company shall not be required to issue or deliver any Shares under this Award prior to fulfillment of all of the following conditions: 

(i) The admission of such Shares to listing on all stock exchanges on which the Shares are then listed; 

(ii) The completion of any registration or other qualification of such Shares under any state or federal law or under rulings or
regulations of the Securities and Exchange Commission or of any other governmental regulatory body, which the Administrator shall, in its absolute discretion, deem necessary or advisable; 

(iii) The obtaining of any approval or other clearance from any state or federal governmental agency that the Administrator shall, in
its absolute discretion, determine to be necessary or advisable; 
 (iv) The receipt by the Company of full payment for such
Shares, including payment of any applicable withholding tax; and 
 (v) The lapse of such reasonable period of time following
the grant of this Award as the Administrator may from time to time establish for reasons of administrative convenience. 
 2.3
Consideration to the Company. In consideration of the grant of the Award by the Company, Participant agrees to render faithful and efficient services to the Company or any Affiliate. Nothing in the Plan or this Agreement shall confer upon
Participant any right to continue in the employ or service of the Company or any Affiliate or shall interfere with or restrict in any way the rights of the Company and its Affiliates, which rights are hereby expressly reserved, to discharge or
terminate the services of Participant at any time for any reason whatsoever, with or without cause, except to the extent expressly provided otherwise in a written agreement between the Company or an Affiliate and Participant. 

2.4 General Restrictions on Transfer of Shares. 
 (a) Permitted Transfers of Shares. Subject to compliance with the restrictions and conditions set forth in this Section 2.4, with the consent of the Administrator, Participant may
Transfer vested Shares subject to the Award (i) by the laws of descent and distribution, or (ii) by gift or domestic relations order to a “family member” (as defined in Rule 701 under the Securities Act) (any such Transfer shall
be referred to as a “Permitted Transfer”). No Permitted Transferee of Participant shall be permitted to Transfer Shares to any Person to whom Participant would not be permitted to Transfer Shares pursuant to the terms of this
Agreement. 
 (b) Conditions to Transfer. No Transfer (including a Permitted Transfer) of any Shares may occur unless and
until (i) the Company shall have received prior written notice of the proposed Transfer, setting forth the proposed Transferee and the circumstance and details thereof (the 

  
 A-5

 
“Notice”); (ii) the Company shall (at its option) have received a written opinion, from an attorney and in a form reasonably satisfactory to the Company, specifying
the nature and circumstances of the proposed Transfer, and stating that the proposed Transfer will not be in violation of any Applicable Law; (iii) if such Transfer occurs prior to the Conversion Date, the Company shall have received from the
Transferee (and the Transferee’s spouse, if such spouse will have a community property interest in the Shares) a written consent to be bound by all of the terms and conditions of this Agreement; and (iv) the Transfer complies with all
other applicable requirements of this Agreement. 
 (c) No Transfers of Unvested Shares. In no event shall Participant
Transfer any Shares that are not vested (or any right or interest therein) to any Person in any manner whatsoever, whether voluntarily or by operation of law or otherwise. Any Transfer of any unvested Shares shall be null and void and of no force or
effect. 
 (d) Transferee Bound by Agreement. Prior to the Conversion Date, the Shares subject to the Award that are
owned or controlled by a Transferee (including a Permitted Transferee) shall for all purposes be subject to the terms of this Agreement (as if the Transferee were Participant), whether or not such Transferee has executed a consent to be bound by
this Agreement. 
 (e) Invalid Sales. Notwithstanding any provision in this Agreement to the contrary, any Transfer under
this Section 2.4 shall be subject to the Company’s Right to Repurchase in Section 2.5. Any purported Transfer of Shares made without fully complying with all of the provisions of this Agreement shall be null and void and
without force or effect. 
 (f) Termination of Transfer Restrictions. The restrictions set forth in this
Section 2.4 shall terminate upon the earliest of the following: (i) written agreement of the Company and Participant, or (ii) the Initial Public Offering. 

2.5 Company’s Right to Repurchase Shares. 
 (a) Events Giving Rise to Right to Repurchase. In the event (i) there is filed by or against Participant (x) a petition to have Participant adjudged a bankrupt or (y) a petition for
reorganization or arrangement or other relief under any law relating to bankruptcy, unless in the case of a petition filed against Participant the same is dismissed within thirty (30) days, (ii) Participant experiences a Termination of
Services by himself or herself without Good Reason, or (iii) Participant experiences a Termination of Services for Cause, the Company shall have, in addition to, and not in lieu of, any other rights hereunder, the right to repurchase the vested
Shares owned by Participant and by his Permitted Transferees, at the price specified in Section 2.5(c) and on the other terms set forth in Section 2.5(d). Participant agrees to give written notice to the Company of the
occurrence, with respect to himself, of an event of the type described in clause (i) of this Section 2.5(a) within ten (10) days after the occurrence of any such event (the “Participant’s Notice”).
[Notwithstanding the foregoing, in no event shall the Company’s right to repurchase be exercised if the Participant experiences a Termination of Services due to the Company’s failure to renew the Participant’s employment agreement
following the expiration of its term.] 
 (b) Manner of Exercise. 

(i) The Company shall exercise its right to repurchase under this Section 2.5 by providing written notice to Participant and
his Permitted Transferees stating that any or all of the vested Shares owned by Participant and by his or her Permitted Transferees are being purchased and specifying the event giving rise to the right to repurchase, which notice shall be delivered
to Participant or his or her Permitted Transferees within sixty (60) days after the later of (A) the occurrence of the event 

  
 A-6

 
giving rise to the right of repurchase or (B) receipt by the Company of Participant’s Notice. Upon delivery of such written notice, the Company shall be obligated to purchase from
Participant, and Participant shall be obligated to sell to the Company, the number of vested Shares set forth in the Company’s notice on the terms and conditions set forth in this Section 2.5. 

(ii) If the Company fails to exercise its right to repurchase within such sixty (60)-day period, the remaining vested Shares that were
subject to such right to repurchase shall remain subject to all of the terms and conditions of this Agreement, excluding only such right to repurchase in this instance and with respect to the specific event that occurred. 

(c) Purchase Price. In the case of any purchase pursuant to clauses (i) or (ii) of Section 2.5(a), the
purchase price shall be equal to the Fair Market Value of the Shares repurchased as of the date of the event giving rise to the Company’s right to repurchase. In the case of any purchase pursuant to Section 2.5(a)(iii), the purchase
price shall be equal to the lower of (i) the Fair Market Value of the Shares to be repurchased as of the date of the event giving rise to the right to repurchase or (ii) the purchase price paid, if any, by Participant to the Company for
the Shares to be repurchased. 
 (d) Payments; Closing. With respect to any Shares purchased by the Company pursuant to
this Section 2.5, the purchase price shall be paid in cash. Subject to Section 2.6, the closing of any purchase and sale made pursuant to this Section 2.5 shall be held at a time specified by the Company within
forty-five (45) days following the exercise of the Company’s right to repurchase at the then principal offices of the Company, or such other place as is agreed upon by the parties thereto. At the closing, (i) Participant shall deliver
to the Company the Shares, free and clear of all liens and encumbrances, and duly endorsed for transfer or accompanied by duly executed stock powers, and (ii) the Company shall deliver to Participant the purchase price in the form of cash.

 (e) Termination of Repurchase Right. The repurchase right set forth in this Section 2.5 shall terminate
upon the earliest of the following: (i) the written agreement of the Company and Participant, or (ii) the Initial Public Offering. 
 2.6 Limitations on Repurchases. The Company shall not exercise any right under this Agreement to purchase more Shares than it is permitted to purchase under the terms of Applicable Law or under the
terms of any indenture or loan or credit agreement. In the event a purchase of the Shares by the Company pursuant to Section 2.5 shall be prohibited by Applicable Law or would cause a default under the terms of any indenture or loan or
credit agreement to which the Company or its Affiliates may be a party, the Company shall so notify Participant. In such event, the obligation of Participant to sell such Shares to the Company and the obligation of the Company to purchase such
Shares from Participant shall be suspended until such time as such prohibition first lapses or is waived and no such default would be caused; provided, however, that the purchase price to be paid by the Company for the Shares shall
accrue interest at the applicable federal rate under the Internal Revenue Code of 1986, as amended. 
 ARTICLE III.

 OTHER PROVISIONS 
 3.1 Tax Withholding and Section 83(b) Election. The Company shall be entitled to require a cash payment by or on behalf of Participant and/or to deduct from other compensation payable to
Participant any sums required by federal, state or local tax law to be withheld with respect to the grant or vesting of the Award or the lapse of the Restrictions hereunder. Participant understands that Section 83(a) of the Internal Revenue
Code taxes as ordinary income the difference between the amount, if any, paid for the Shares and the Fair Market Value of such Shares at the time the Restrictions on such Shares lapse. Participant understands that, notwithstanding the preceding
sentence, Participant may elect 

  
 A-7

 
to be taxed at the time of the Grant Date, rather than at the time the Restrictions lapse, by filing an election under Section 83(b) of the Code (an “83(b) Election”)
with the Internal Revenue Service within 30 days of the Grant Date, a sample of which is set forth as Exhibit F to the Grant Notice. In the event Participant files an 83(b) Election, Participant shall provide the Company a copy thereof prior
to the expiration of such 30 day period. Participant understands that in the event an 83(b) Election is filed with the Internal Revenue Service within such time period, Participant will recognize ordinary income in an amount equal to the difference
between the amount, if any, paid for the Shares and the Fair Market Value of such Shares as of the Grant Date. Participant further understands that an additional copy of such 83(b) Election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls. Participant acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to the Award hereunder, and does not purport to
be complete. 
 PARTICIPANT FURTHER ACKNOWLEDGES THAT THE COMPANY IS NOT RESPONSIBLE FOR FILING PARTICIPANT’S 83(b) ELECTION, AND THE
COMPANY HAS DIRECTED PARTICIPANT TO SEEK INDEPENDENT ADVICE REGARDING THE APPLICABLE PROVISIONS OF THE INTERNAL REVENUE CODE, THE INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH PARTICIPANT MAY RESIDE, AND THE TAX CONSEQUENCES
OF PARTICIPANT’S DEATH. 
 PARTICIPANT HEREBY ASSUMES ALL RESPONSIBILITY FOR FILING PARTICIPANT’S 83(b) ELECTION AND PAYING ANY TAXES
RESULTING FROM SUCH ELECTION OR FROM FAILURE TO FILE THE ELECTION AND PAYING TAXES RESULTING FROM THE LAPSE OF THE RESTRICTIONS ON THE UNVESTED SHARES. 
 PARTICIPANT UNDERSTANDS THAT PARTICIPANT MAY SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF PARTICIPANT’S PURCHASE OR DISPOSITION OF THE SHARES AND PARTICIPANT REPRESENTS THAT PARTICIPANT IS NOT
RELYING ON THE COMPANY FOR ANY TAX ADVICE. 
 3.2 Rights as Stockholder. Except as otherwise provided herein, upon the
Grant Date Participant shall have all the rights of a stockholder with respect to the Shares, subject to the Restrictions herein, including the right to vote the Shares; provided, however, that any distributions or dividends with respect to
unvested Shares shall be held by the Company and shall be released to Participant only as the underlying Shares vest; provided, further, that at the discretion of the Company, and prior to the delivery of Shares, Participant may be required
to execute a stockholders agreement in such form as shall be determined by the Company. 
 3.3 Not a Contract of
Employment. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue to serve as an employee or other service provider of the Company or any of its Affiliates. 

3.4 Nonsolicitation. As a condition of being granted the Shares subject to the Award, Participant agrees
that, during the period beginning on the date of Participant’s Termination of Services and ending on the second
(2nd) anniversary thereof, Participant will not, and
will not assist any other Person to, hire, solicit or recruit the employment or services of (whether as an employee, officer or director) any individual who, at the time of such hiring, solicitation or recruitment or at any time during the six
(6) months preceding such Termination of Services, was an executive employee or officer of the Company or any Affiliate; provided, however, that if Participant is party to an employment agreement with the Company or its Affiliate,
any nonsolicitation provision in such agreement shall govern. 

  
 A-8

 3.5 Market Stand Off. Participant agrees not to sell, make any short sale of, loan,
grant any option for the purchase of, or otherwise dispose of (including by means of sales pursuant to Rule 144), any Shares of the Company’s capital stock during the 180-day period beginning on the effective date of the registration statement
for an Initial Public Offering and during the 90-day period beginning on the effective date of the registration statement for any other underwritten offering (except as part of such underwritten registration), unless the managing underwriters for
the registered public offering otherwise agree. 
 3.6 Conversion of Shares. Immediately upon the Conversion Date, each
Share held by Participant hereunder (whether vested or unvested) shall automatically convert to one share of Class A Common Stock, and such shares of Class A Common Stock shall otherwise remain subject to the provisions of this Agreement.

 3.7 Governing Law. The laws of the State of Delaware shall govern the interpretation, validity, administration,
enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws. 
 3.8 Conformity to Securities Laws. Participant acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of the Securities Act and the
Exchange Act, and any and all regulations and rules promulgated thereunder by the Securities and Exchange Commission. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Award is granted, only in such a manner as
to conform to such laws, rules and regulations. To the extent permitted by Applicable Law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations. 

3.9 Amendment, Suspension and Termination. To the extent permitted by the Plan, this Agreement may be wholly or partially amended
or otherwise modified, suspended or terminated at any time or from time to time by the Committee or the Board, provided, that, except as may otherwise be provided by the Plan, no amendment, modification, suspension or termination of this
Agreement shall adversely affect the Award in any material way without the prior written consent of Participant. 
 3.10
Notices. Notices required or permitted hereunder shall be given in writing and shall be deemed effectively given upon personal delivery or upon deposit in the United States mail by certified mail, with postage and fees prepaid, addressed to
Participant to his or her address shown in the Company records, and to the Company at its principal executive office. 
 3.11
Application to Other Stock. In the event any capital stock of the Company or any other corporation shall be distributed on, with respect to, or in exchange for, the Shares subject to the Award as a stock dividend, stock split,
reclassification or recapitalization in connection with any merger or reorganization or otherwise, all restrictions, rights and obligations set forth in this Agreement shall apply with respect to such other capital stock to the same extent as they
are, or would have been applicable, to the Shares subject to the Award on or with respect to which such other capital stock was distributed. 
 3.12 Additional Documents. Each party agrees to execute any and all further documents and writings, and to perform such other actions, that may be or become reasonably necessary or expedient to be
made effective and carry out this Agreement. 
 3.13 No Third-Party Benefits. Except as otherwise expressly provided in
this Agreement, none of the provisions of this Agreement shall be for the benefit of, or enforceable by, any third-party beneficiary. 

  
 A-9

 3.14 Successors and Assigns. The Company may assign any of its rights under this
Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement shall be binding upon Participant and his
or her heirs, executors, administrators, successors and assigns. 
 3.15 Severability. The validity, legality or
enforceability of the remainder of this Agreement shall not be affected even if one or more of the provisions of this Agreement shall be held to be invalid, illegal or unenforceable in any respect. 

3.16 Equitable Relief. Participant acknowledges that, in the event of a threatened or actual breach of any of the provisions of
this Agreement, damages alone will be an inadequate remedy, and such breach will cause the Company great, immediate and irreparable injury and damage. Accordingly, Participant agrees that the Company shall be entitled to injunctive and other
equitable relief, and that such relief shall be in addition to, and not in lieu of, any remedies it may have at law or under this Agreement. 
 3.17 Arbitration. 
 (a) General. Any controversy, dispute, or claim
between the parties to this Agreement, including any claim arising out of, in connection with, or in relation to, the formation, interpretation, performance or breach of this Agreement shall be settled exclusively by arbitration, before a single
arbitrator, in accordance with this Section 3.17 and the then-applicable JAMS Employment Arbitration Rules and Procedures (“JAMS Rules”). Judgment upon any award rendered by the arbitrator may be entered by any
state or federal court having jurisdiction thereof. Such arbitration shall be administered by JAMS. Arbitration shall be the exclusive remedy for determining any such dispute, regardless of its nature. Notwithstanding the foregoing, either party may
in an appropriate matter apply to a court for provisional relief, including a temporary restraining order or a preliminary injunction, on the ground that the award to which the applicant may be entitled in arbitration may be rendered ineffectual
without provisional relief. Unless mutually agreed by the parties otherwise, any arbitration shall take place in Orange County, California. 
 (b) Selection of Arbitrator. In the event the parties are unable to agree upon an arbitrator, the arbitrator shall be selected in accordance with the JAMS Rules. 

(c) Applicability of Arbitration; Remedial Authority. This agreement to resolve any disputes by binding arbitration shall extend
to claims against any parent, subsidiary or affiliate of each party, and, when acting within such capacity, any officer, director, shareholder, employee or agent of each party, or of any of the above, and shall apply as well to claims arising out of
state and federal statutes and local ordinances as well as to claims arising under the common law. In the event of a dispute subject to this paragraph, the parties to the arbitration shall be entitled to reasonable discovery subject to the
discretion of the arbitrator. The remedial authority of the arbitrator (which shall include the right to grant injunctive or other equitable relief) shall be the same as, but no greater than, would be the remedial power of a court having
jurisdiction over the parties and their dispute. The arbitrator shall, upon an appropriate motion, dismiss any claim without an evidentiary hearing if the party bringing the motion establishes that he or it would be entitled to summary judgment if
the matter had been pursued in court litigation. In the event of a conflict between the JAMS Rules and these procedures, the provisions of these procedures shall govern. 
 (d) Fees and Costs. Any filing or administrative fees shall be borne initially by the party requesting arbitration. The Company shall be responsible for the costs and fees of the arbitration.
Notwithstanding the foregoing, each Party shall be responsible for and pay their own attoneys’ fees and costs incurred in connection with such arbitration, except as may be awarded to a prevailing party under Applicable Law. 

  
 A-10

 (e) Award Final and Binding. The arbitrator shall render an award and written
opinion, and the award shall be final and binding upon the parties. If any of the provisions of this paragraph, or of this Agreement, are determined to be unlawful or otherwise unenforceable, in whole or in part, such determination shall not affect
the validity of the remainder of this Agreement, and this Agreement shall be reformed to the extent necessary to carry out its provisions to the greatest extent possible and to insure that the resolution of all conflicts between the parties,
including those arising out of statutory claims, shall be resolved by neutral, binding arbitration. If a court should find that the arbitration provisions of this Agreement are not absolutely binding, then the parties intend any arbitration decision
and award to be fully admissible in evidence in any subsequent action, given great weight by any finder of fact, and treated as determinative to the maximum extent permitted by law. 

3.18 Headings. The section headings in this Agreement are inserted only as a matter of convenience, and in no way define, limit,
extend or interpret the scope of this Agreement or of any particular section. 
 3.19 Number and Gender. Throughout this
Agreement, as the context may require, (a) the masculine gender includes the feminine and the neuter gender includes the masculine and the feminine; (b) the singular tense and number includes the plural, and the plural tense and number
includes the singular; (c) the past tense includes the present, and the present tense includes the past; (d) references to parties, sections, paragraphs and exhibits mean the parties, sections, paragraphs and exhibits of and to this
Agreement; and (e) periods of days, weeks or months mean calendar days, weeks or months. 
 3.20 Limitations Applicable
to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the Award and this Agreement shall be subject to any additional
limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by
Applicable Law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule. 

3.21 Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein
provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets.
Participant shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Shares issuable hereunder. 

3.22 Entire Agreement. The Plan, the Grant Notice and this Agreement (including all Exhibits thereto) constitute the entire
agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof. 
 3.23 Counterparts. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original, but all of which, together, shall constitute one and the
same instrument.

Secretary 
 William Lyon Homes 

4695 MacArthur Court 
 8th Floor 

Newport Beach, CA 92660 
 Ladies and Gentlemen:

 As escrow agent (the “Escrow Agent”) for both William Lyon Homes, a Delaware corporation (the
“Company”), and the undersigned recipient of shares of common stock of the Company (the “Participant”), you are hereby authorized and directed to hold in escrow the documents delivered to you pursuant
to the terms of that certain Restricted Stock Award Agreement (“Agreement”) between the Company and the undersigned (the “Escrow”), including the stock certificate and the Assignment Separate from
Certificate, in accordance with the following instructions: 
 1. In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the “Company”) exercises the Company’s right to repurchase Participant’s vested shares pursuant to Section 2.5 of the Agreement (the “Repurchase
Option”), the Company shall give to Participant and you a written notice specifying the number of shares of stock to be purchased, the purchase price and the time for a closing hereunder at the principal office of the Company. Participant and
the Company hereby irrevocably authorize and direct you to close the transaction contemplated by such notice in accordance with the terms of said notice. 
 2. As of the date of closing of the repurchase indicated in such notice, you are directed (a) to date the Assignment Separate from Certificate necessary for the repurchase and transfer in question,
(b) to fill in the number of shares being repurchased and transferred, and (c) to deliver the same, together with the certificate evidencing the shares of stock to be repurchased and transferred, to the Company or its assignee. 

3. Participant irrevocably authorizes the Company to deposit with you any certificates evidencing shares of stock to be held by you
hereunder and any additions and substitutions to said shares as set forth in the Agreement. Participant does hereby irrevocably constitute and appoint you as Participant’s attorney-in-fact and agent for the term of this escrow to execute with
respect to such securities all documents necessary or appropriate to make such securities negotiable and to complete any transaction herein contemplated, including but not limited to the filing with any applicable state blue sky authority of any
required applications for consent to, or notice of transfer of, the securities. Subject to the provisions of this paragraph 3 and the Agreement, Participant shall exercise all rights and privileges of a stockholder of the Company while the
stock is held by you. 
 4. Upon written request of Participant, but no more than once per calendar year, unless the
Company’s Repurchase Option has been exercised, you will deliver to Participant a certificate or certificates representing so many shares of stock as are not then subject to the Repurchase Option. Within

  
 E-1

 
60 days after the termination of the Company’s Repurchase Option in accordance with the terms of the Agreement, you will deliver to Participant a certificate or certificates representing the
aggregate number of shares held or issued pursuant to the Agreement and not repurchased pursuant to the Repurchase Option. 
 5.
If at the time of termination of this escrow you should have in your possession any documents, securities, or other property belonging to Participant, you shall deliver all of the same to Participant and shall be discharged of all further
obligations hereunder. 
 6. Your duties hereunder may be altered, amended, modified or revoked only by a writing signed by all
of the parties hereto. 
 7. You shall be obligated only for the performance of such duties as are specifically set forth herein
and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed by you to be genuine and to have been signed or presented by the proper party or parties. You shall not be personally liable for any act
you may do or omit to do hereunder as Escrow Agent or as attorney-in-fact for Participant while acting in good faith, and any act done or omitted by you pursuant to the advice of your own attorneys shall be conclusive evidence of such good faith.
