 VISTO CORPORATION 1996 STOCK
PLAN 
 SECTION 1. ESTABLISHMENT AND PURPOSE. 
 The purpose of the Plan is to offer selected persons an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by purchasing Shares of the
Company’s Stock. The Plan provides both for the direct award or sale of Shares and for the grant of Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well as ISOs intended to qualify under
Section 422 of the Code. 
 Capitalized terms are defined in Section 12. 

SECTION 2. ADMINISTRATION. 
 (a) Committees of the Board of Directors. The Plan may be administered by one or more Committees. Each Committee shall consist of one or more members of the Board of Directors who have been
appointed by the Board of Directors. Each Committee shall have such authority and be responsible for such functions as the Board of Directors has assigned to it. If no Committee has been appointed, the entire Board of Directors shall administer the
Plan. Any reference to the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function. 

(b) Authority of the Board of Directors. Subject to the provisions of the Plan, the Board of Directors shall have full authority
and discretion to take any actions it deems necessary or advisable for the administration of the Plan. All decisions, interpretations and other actions of the Board of Directors shall be final and binding on all Purchasers, all Optionees and all
persons deriving their rights from a Purchaser or Optionee. 
 SECTION 3. ELIGIBILITY. 

(a) General Rule. Only Employees, Outside Directors and Consultants shall be eligible for the grant of Options or the direct award
or sale of Shares. Only Employees shall be eligible for the grant of ISOs. 
 (b) Ten-Percent Stockholders. A person who
owns more than 10% of the total combined voting power of all classes of outstanding stock of the Company, its Parent or any of its Subsidiaries shall not be eligible for designation as an Optionee or Purchaser unless (i) the Exercise Price is
at least 110% of the Fair Market Value of a Share on the date of grant, (ii) the Purchase Price (if any) is at least 100% of the Fair Market Value of a Share and (iii) in the case of an ISO, such ISO by its terms is not exercisable after
the expiration of five years from the date of grant. For purposes of this Subsection (b), in determining stock ownership, the attribution rules of Section 424(d) of the Code shall be applied.

 SECTION 4. STOCK SUBJECT TO PLAN. 

(a) Basic Limitation. Shares offered under the Plan may be authorized but unissued Shares or treasury Shares. The aggregate number
of Shares that may be issued under the Plan (upon exercise of Options or other rights to acquire Shares) shall not exceed 31,554,8251 Shares, subject to Subsection (b) below and Section 8. All of these Shares may be issued upon the exercise of
ISOs. The number of Shares that are subject to Options or other rights outstanding at any time under the Plan shall not exceed the number of Shares that then remain available for issuance under the Plan. The Company, during the term of the Plan,
shall at all times reserve and keep available sufficient Shares to satisfy the requirements of the Plan. 
 (b) Additional
Shares. In the event that any outstanding Option or other right for any reason expires or is canceled or otherwise terminated, the Shares allocable to the unexercised portion of such Option or other right shall again be available for the
purposes of the Plan. In the event that Shares issued under the Plan are reacquired by the Company, such Shares shall again be available for the purposes of the Plan. 
 SECTION 5. TERMS AND CONDITIONS OF AWARDS OR SALES. 
 (a) Stock Purchase
Agreement. Each award or sale of Shares under the Plan (other than upon exercise of an Option) shall be evidenced by a Stock Purchase Agreement between the Purchaser and the Company. Such award or sale shall be subject to all applicable terms
and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Stock Purchase Agreement. The provisions of the various
Stock Purchase Agreements entered into under the Plan need not be identical.

 (b) Duration of Offers and Nontransferability of Rights. Any right to acquire Shares
under the Plan (other than an Option) shall automatically expire if not exercised by the Purchaser within 30 days after the grant of such right was communicated to the Purchaser by the Company. Such right shall not be transferable and shall be
exercisable only by the Purchaser to whom such right was granted. 
 (c) Purchase Price. The Purchase Price of Shares to
be offered under the Plan shall not be less than 85% of the Fair Market Value of such Shares, and a higher percentage may be required by Section 3(b). Subject to the preceding sentence, the Purchase Price shall be determined by the Board of
Directors at its sole discretion. The Purchase Price shall be payable in a form described in Section 7. 
 (d)
Withholding Taxes. As a condition to the purchase of Shares, the Purchaser shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may
arise in connection with such purchase. 
 (e) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares awarded
or sold under the Plan shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the
applicable Stock Purchase Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of a Purchaser who is not an officer of the Company, an Outside Director or a Consultant, any right to
repurchase a Purchaser’s Shares at the original Purchase Price (if any) upon termination of the Purchaser’s Service shall lapse at least as rapidly as the following schedule: 

 

					
	 Anniversary of Date of Sale or Award
	  	Percentage of
Shares Vested	 
		
	 First
	  	 	20	% 
	 Second
	  	 	40	% 
	 Third
	  	 	60	% 
	 Fourth
	  	 	80	% 
	 Fifth
	  	 	100	% 

 Any such repurchase right may be exercised only within 90 days after the termination of the Purchaser’s Service for
cash or for cancellation of indebtedness incurred in purchasing the Shares. 
 SECTION 6. TERMS AND CONDITIONS OF OPTIONS. 

(a) Stock Option Agreement. Each grant of an Option under the Plan shall be evidenced by a Stock Option Agreement between the
Optionee and the Company. Such Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems
appropriate for inclusion in a Stock Option Agreement. The provisions of the various Stock Option Agreements entered into under the Plan need not be identical. 

  
 3 








 (b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares
that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 8. The Stock Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option. 

(c) Exercise Price. Each Stock Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less
than 100% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b). The Exercise Price of a Nonstatutory Option shall not be less than 85% of the Fair Market Value of a Share on the date
of grant, and a higher percentage may be required by Section 3(b). Subject to the preceding two sentences, the Exercise Price under any Option shall be determined by the Board of Directors at its sole discretion. The Exercise Price shall be
payable in a form described in Section 7. 
 (d) Withholding Taxes. As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with such exercise. The Optionee shall also make such
arrangements as the Board of Directors may require for the satisfaction of any federal, state, local or foreign withholding tax obligations that may arise in connection with the disposition of Shares acquired by exercising an Option. 

(e) Exercisability. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become
exercisable. In the case of an Option granted to an Optionee who is not an officer of the Company, an Outside Director or a Consultant, the Option shall become exercisable at least as rapidly as set forth in the following schedule: 

 

					
	 Anniversary of Date of Option Grant
	  	Percentage of Shares
Exercisable	 
		
	 First
	  	 	20	% 
	 Second
	  	 	40	% 
	 Third
	  	 	60	% 
	 Fourth
	  	 	80	% 
	 Fifth
	  	 	100	% 

 Subject to the preceding sentence, the exercisability provisions of any Stock Option Agreement shall be determined by the
Board of Directors at its sole discretion. 
 (f) Basic Term. The Stock Option Agreement shall specify the term of the
Option. The term shall not exceed 10 years from the date of grant, and a shorter term may be required by Section 3(b). Subject to the preceding sentence, the Board of Directors at its sole discretion shall determine when an Option is to expire.


  
 4 








 (g) Nontransferability. No Option shall be transferable by the Optionee other than by
beneficiary designation, will or the laws of descent and distribution. An Option may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative. No Option or interest therein may
be transferred, assigned, pledged or hypothecated by the Optionee during the Optionee’s lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process. 

(h) Termination of Service (Except by Death). If an Optionee’s Service terminates for any reason other than the
Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following occasions: 

(i) The expiration date determined pursuant to Subsection (f) above; 

(ii) The date three months after the termination of the Optionee’s Service for any reason other than Disability, or
such later date as the Board of Directors may determine; or 
 (iii) The date six months after the termination of
the Optionee’s Service by reason of Disability, or such later date as the Board of Directors may determine. 
 The Optionee may exercise
all or part of the Optionee’s Options at any time before the expiration of such Options under the preceding sentence, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became
exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). The balance of such Options shall lapse when the Optionee’s Service
terminates. In the event that the Optionee dies after the termination of the Optionee’s Service but before the expiration of the Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the executors or
administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that such Options had become exercisable before the
Optionee’s Service terminated (or became exercisable as a result of the termination) and the underlying Shares had vested before the Optionee’s Service terminated (or vested as a result of the termination). 

(i) Leaves of Absence. For purposes of Subsection (h) above, Service shall be deemed to continue while the Optionee is on a
bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company). 

(j) Death of Optionee. If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire on the
earlier of the following dates: 
 (i) The expiration date determined pursuant to Subsection (f) above; or

 (ii) The date 12 months after the Optionee’s death, or such later date as the Board of Directors may
determine. 

  
 5 








 All or part of the Optionee’s Options may be exercised at any time before the expiration of such
Options under the preceding sentence by the executors or administrators of the Optionee’s estate or by any person who has acquired such Options directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the
extent that such Options had become exercisable before the Optionee’s death or became exercisable as a result of the death and the underlying Shares had vested before the Optionee’s Service death (or vested as a result of the death). The
balance of such Options shall lapse when the Optionee dies. 
 (k) No Rights as a Stockholder. An Optionee, or a
transferee of an Optionee, shall have no rights as a stockholder with respect to any Shares covered by the Optionee’s Option until such person becomes entitled to receive such Shares by filing a notice of exercise and paying the Exercise Price
pursuant to the terms of such Option. 
 (l) Modification, Extension and Assumption of Options. Within the limitations of
the Plan, the Board of Directors may modify, extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for the same or a
different number of Shares and at the same or a different Exercise Price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s rights or increase the Optionee’s
obligations under such Option. 
 (m) Restrictions on Transfer of Shares and Minimum Vesting. Any Shares issued upon
exercise of an Option shall be subject to such special forfeiture conditions, rights of repurchase, rights of first refusal and other transfer restrictions as the Board of Directors may determine. Such restrictions shall be set forth in the
applicable Stock Option Agreement and shall apply in addition to any restrictions that may apply to holders of Shares generally. In the case of an Optionee who is not an officer of the Company, an Outside Director or a Consultant, any right to
repurchase an Optionee’s Shares at the original Exercise Price upon termination of the Optionee’s Service shall lapse at least as rapidly as 20% per year over the five-year period commencing on the date of the option grant. Any such
repurchase right may be exercised for cash or for cancellation of indebtedness incurred in purchasing the Shares only within 90 days after the later of (A) the termination of the Optionee’s Service or (B) the date of the option
exercise. 
 SECTION 7. PAYMENT FOR SHARES. 
 (a) General Rule. The entire Purchase Price or Exercise Price of Shares issued under the Plan shall be payable in cash or cash equivalents at the time when such Shares are purchased, except as
otherwise provided in this Section 7. 
 (b) Surrender of Stock. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part with Shares owned by the Optionee or the Optionee’s representative. Such Shares shall be surrendered to the Company in good form for transfer and


  
 6 








 
shall be valued at their Fair Market Value on the date when the Option is exercised. This Subsection (b) shall not apply to the extent that acceptance of Shares in payment of the Exercise
Price would cause the Company to recognize compensation expense with respect to the Option for financial reporting purposes. 

(c) Services Rendered. At the discretion of the Board of Directors, Shares may be awarded under the Plan in consideration of
services rendered to the Company, a Parent or a Subsidiary prior to the award. 
 (d) Promissory Note. To the extent that
a Stock Option Agreement or Stock Purchase Agreement so provides, all or a portion of the Exercise Price or Purchase Price (as the case may be) of Shares issued under the Plan may be paid with a full-recourse promissory note. The Shares shall be
pledged as security for payment of the principal amount of the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate, if any, required to avoid (i) the
imputation of additional interest under the Code and (ii) variable accounting under the applicable guidelines issued by the Financial Accounting Standards Board. Subject to the foregoing, the Board of Directors (at its sole discretion) shall
specify the term, interest rate, amortization requirements, if any, and other provisions of such note. 
 (e)
Exercise/Sale. To the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made all or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities
broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company in payment of all or part of the Exercise Price and any withholding taxes. 

(f) Exercise/Pledge. To the extent that a Stock Option Agreement so provides, and if Stock is publicly traded, payment may be made
all or in part by the delivery (on a form prescribed by the Company) of an irrevocable direction to pledge Shares to a securities broker or lender approved by the Company, as security for a loan, and to deliver all or part of the loan proceeds to
the Company in payment of all or part of the Exercise Price and any withholding taxes. 
 (g) Other Forms of Payment. At
the discretion of the Board of Directors, the Purchase Price or Exercise Price of Shares issued under the Plan may be paid in any other form permitted by the Delaware General Corporation Law, as amended. 

SECTION 8. ADJUSTMENT OF SHARES. 
 (a) General. In the event of a subdivision of the outstanding Stock, a declaration of a dividend payable in Shares or a combination or consolidation of the outstanding Stock into a lesser number of
Shares, corresponding adjustments shall automatically be made in each of (i) the number of Shares available for future grants under Section 4, (ii) the number of Shares covered by each outstanding Option and (iii) the Exercise
Price under each outstanding Option. In the event of a declaration of an extraordinary dividend payable in a form other than Shares in an amount that has a material effect on the Fair Market Value of the Stock, a recapitalization, a


  
 7 








 
spin-off, a reclassification or a similar occurrence, the Board of Directors at its sole discretion may make appropriate adjustments in one or more of (i) the number of Shares available for
future grants under Section 4, (ii) the number of Shares covered by each outstanding Option or (iii) the Exercise Price under each outstanding Option. 
 (b) Mergers and Consolidations. In the event that the Company is a party to a merger or consolidation, all outstanding Options shall be subject to the agreement of merger or consolidation, which
does not have to provide that all outstanding Options (or a portion thereof) be treated in an identical manner. Such agreement, without the Optionees’ consent, may provide for one or more of the following: 

(i) The continuation of any outstanding Options by the Company (if the Company is the surviving corporation). 

(ii) The assumption of the Plan and any outstanding Options by the surviving corporation or its parent in a manner that
complies with Section 424(a) of the Code (whether or not such Options are ISOs). 
 (iii) The substitution
by the surviving corporation or its parent of new options for any outstanding Options in a manner that complies with Section 424(a) of the Code (whether or not such Options are ISOs). 

(iv) Full exercisability of any outstanding Options and full vesting of the Shares subject to such Options, followed by
the cancellation of such Options. The full exercisability of any Options and full vesting of the Shares subject to such Options may be contingent on the closing of such merger or consolidation. The Optionees shall be able to exercise such Options
during a period of not less than five full business days preceding the closing date of such merger or consolidation, unless (A) a shorter period is required to permit a timely closing of such merger or consolidation and (B) such shorter
period still offers the Optionees a reasonable opportunity to exercise such Options. Any exercise of such Options during such period may be contingent on the closing of such merger or consolidation. 

(v) The cancellation of any outstanding Options and a payment to the Optionees equal to the excess of (A) the Fair
Market Value of the Shares subject to such Options (whether or not such Options are then exercisable or such Shares are then vested) as of the closing date of such merger or consolidation over (B) their Exercise Price. Such payment shall be
made in the form of cash, cash equivalents, or securities of the surviving corporation or its parent with a Fair Market Value equal to the required amount. Such payment may be made in installments and may be deferred until the date or dates when
such Options would have become exercisable or such Shares would have vested. Such payment may be subject to vesting based on the Optionee’s continuing Service, provided that the vesting schedule shall not be less favorable to the Optionee than
the schedule under which such Options would have become exercisable or such Shares would have vested. If the Exercise Price of the Shares subject to such Options exceeds 

  
 8 








 
the Fair Market Value of such Shares, then such Options may be cancelled without making a payment to the Optionees. For purposes of this Paragraph (v), the Fair Market Value of any security
shall be determined without regard to any vesting conditions that may apply to such security. 
 (c) Reservation of
Rights. Except as provided in this Section 8, an Optionee or Purchaser shall have no rights by reason of (i) any subdivision or consolidation of shares of stock of any class, (ii) the payment of any dividend or (iii) any
other increase or decrease in the number of shares of stock of any class. Any issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

17,303,880 to 31,954,825 shares (the formula produced a share increase of 17,281,366 shares but 2,030,421 of such shares were transferred on the same date to the Company’s 2003 U.K. Stock Plan and 600,000 of such shares were transferred on the
same date to the Company’s International Stock Plan). On October 5, 2005, the Board of Directors amended and restated the Plan to update its terms. On February 1, 2006 the Board of Directors authorized a decrease in the number of
shares issuable over the term of the Plan by 400,000 shares from 31,954,825 shares to 31,554,825 shares for the transfer of such shares to the Company’s International Stock Plan. The Plan shall terminate automatically 10 years after the later
of (i) its adoption by the Board of Directors or (ii) the most recent increase in the number of Shares reserved under Section 4 that was approved by the Company’s stockholders. The Plan may be terminated on any earlier date
pursuant to Subsection (b) below. 
 (b) Right to Amend or Terminate the Plan. The Board of Directors may amend,
suspend or terminate the Plan at any time and for any reason; provided, however, that any amendment of the Plan which increases the number of Shares available for issuance under the Plan (except as provided in Section 8), or which materially
changes the class of persons who are eligible for the grant of ISOs, shall be subject to the approval of the Company’s stockholders. Stockholder approval shall not be required for any other amendment of the Plan. If the stockholders fail to
approve an increase in the number of Shares reserved under Section 4 within 12 months after its adoption by the Board of Directors, then any grants, exercises or sales that have already occurred in reliance on such increase shall be rescinded
and no additional grants, exercises or sales shall thereafter be made in reliance on such increase. 
 (c) Effect of
Amendment or Termination. No Shares shall be issued or sold under the Plan after the termination thereof, except upon exercise of an Option granted prior to such termination. The termination of the Plan, or any amendment thereof, shall not

 VISTO CORPORATION 1996 STOCK
PLAN: 
 STOCK OPTION AGREEMENT 

SECTION 1. GRANT OF OPTION. 
 (a) Option. On the terms and conditions set forth in the Notice of Stock Option Grant and this Agreement, the Company grants to the Optionee on the Date of Grant the option to purchase at the
Exercise Price the number of Shares set forth in the Notice of Stock Option Grant. The Exercise Price is agreed to be at least 100% of the Fair Market Value per Share on the Date of Grant (110% of Fair Market Value if Section 3(b) of the Plan
applies). This option is intended to be an ISO or a Nonstatutory Option, as provided in the Notice of Stock Option Grant. 
 (b)
Stock Plan and Defined Terms. This option is granted pursuant to the Plan, a copy of which the Optionee acknowledges having received. The provisions of the Plan are incorporated into this Agreement by this reference. Capitalized terms are
defined in Section 14 of this Agreement. 
 SECTION 2. RIGHT TO EXERCISE. 

(a) Exercisability. Subject to Subsections (b) and (c) below and the other conditions set forth in this Agreement, all or
part of this option may be exercised prior to its expiration at the time or times set forth in the Notice of Stock Option Grant. Shares purchased by exercising this option may be subject to the Right of Repurchase under Section 7. 

(b) $100,000 Limitation. If this Option is designated as an ISO in the Notice of Stock Option Grant, then the Optionee’s
right to exercise this option shall be deferred to the extent (and only to the extent) that this option otherwise would not be treated as an ISO by reason of the $100,000 annual limitation under Section 422(d) of the Code, except that:

 (i) The Optionee’s right to exercise this option shall not be deferred with respect to that portion of
the Shares subject to this option whose Fair Market Value as of the Date of Grant exceeds $500,000; and 
 (ii)
The Optionee’s right to exercise this option shall no longer be deferred in the event that (A) a Change in Control occurs, (B) this option is not assumed 







 
by the surviving corporation or its parent and (C) the surviving corporation or its parent does not substitute its own option for this option. 

(c) Stockholder Approval. Any other provision of this Agreement notwithstanding, no portion of this option shall be exercisable at
any time prior to the approval of the Plan by the Company’s stockholders. 
 SECTION 3. NO TRANSFER OR ASSIGNMENT OF OPTION.

 Except as otherwise provided in this Agreement, this option and the rights and privileges conferred hereby shall not be
sold, pledged or otherwise transferred (whether by operation of law or otherwise) and shall not be subject to sale under execution, attachment, levy or similar process. 
 SECTION 4. EXERCISE PROCEDURES. 
 (a) Notice of Exercise. The
Optionee or the Optionee’s representative may exercise this option by giving written notice to the Company pursuant to Section 13(c). The notice shall specify the election to exercise this option, the number of Shares for which it is being
exercised and the form of payment. The notice shall be signed by the person exercising this option. In the event that this option is being exercised by the representative of the Optionee, the notice shall be accompanied by proof (satisfactory to the
Company) of the representative’s right to exercise this option. The Optionee or the Optionee’s representative shall deliver to the Company, at the time of giving the notice, payment in a form permissible under Section 5 for the full
amount of the Purchase Price. 
 (b) Issuance of Shares. After receiving a proper notice of exercise, the Company shall
cause to be issued a certificate or certificates for the Shares as to which this option has been exercised, registered in the name of the person exercising this option (or in the names of such person and his or her spouse as community property or as
joint tenants with right of survivorship). The Company shall cause such certificate or certificates to be deposited in escrow or delivered to or upon the order of the person exercising this option. 

(c) Withholding Taxes. In the event that the Company determines that it is required to withhold any tax as a result of the
exercise of this option, the Optionee, as a condition to the exercise of this option, shall make arrangements satisfactory to the Company to enable it to satisfy all withholding requirements. The Optionee shall also make arrangements satisfactory to
the Company to enable it to satisfy any withholding requirements that may arise in connection with the vesting or disposition of Shares purchased by exercising this option. 
 SECTION 5. PAYMENT FOR STOCK. 
 (a) Cash. All or part of the Purchase
Price may be paid in cash or cash equivalents. 
 (b) Surrender of Stock. All or part of the Purchase Price may be paid
by the surrender of Shares in good form for transfer. Such Shares must have a fair market value (as determined by the Board of Directors) on the date of exercise of this option which, together with any


  
 2 








 
amount paid in another form permissible under this Section 5, is equal to the Purchase Price. The Optionee shall not surrender Shares in payment of the Exercise Price if such surrender would
cause the Company to recognize compensation expense with respect to the option for financial reporting purposes. 
 (c)
Exercise/Sale. If Stock is publicly traded, all or part of the Purchase Price and any withholding taxes may be paid by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the
Company to sell Shares and to deliver all or part of the sales proceeds to the Company. 
 (d) Exercise/Pledge. If Stock
is publicly traded, all or part of the Purchase Price and any withholding taxes may be paid by the delivery (on a form prescribed by the Company) of an irrevocable direction to pledge Shares to a securities broker or lender approved by the Company,
as security for a loan, and to deliver all or part of the loan proceeds to the Company. 
 SECTION 6. TERM AND EXPIRATION. 

(a) Basic Term. This option shall in any event expire on the expiration date set forth in the Notice of Stock Option Grant, which
date is 10 years after the Date of Grant (five years after the Date of Grant if this option is designated as an ISO in the Notice of Stock Option Grant and Section 3(b) of the Plan applies),

 (ii) The date three months after the termination of the Optionee’s Service
for any reason other than Disability; or 
 (iii) The date six months after the termination of the
Optionee’s Service by reason of Disability. 
 The Optionee may exercise all or part of this option at any time before its expiration under
the preceding sentence, but only to the extent that this option had become exercisable before the Optionee’s Service terminated. When the Optionee’s Service terminates, this option shall expire immediately with respect to the number of
Shares for which this option is not yet exercisable and with respect to any Restricted Shares. In the event that the Optionee dies after termination of Service but before the expiration of this option, all or part of this option may be exercised
(prior to expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired this option directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that this
option had become exercisable before the Optionee’s Service terminated. 
 (c) Death of the Optionee. If the
Optionee dies while in Service, then this option shall expire on the earlier of the following dates: 

  
 3 








 (i) The expiration date determined pursuant to Subsection (a) above;
or 
 (ii) The date 12 months after the Optionee’s death. 

All or part of this option may be exercised at any time before its expiration under the preceding sentence by the executors or administrators of the
Optionee’s estate or by any person who has acquired this option directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that this option had become exercisable before the Optionee’s death. When
the Optionee dies, this option shall expire immediately with respect to the number of Shares for which this option is not yet exercisable and with respect to any Restricted Shares. 

(d) Leaves of Absence. For any purpose under this Agreement, Service shall be deemed to continue while the Optionee is on a bona
fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for such purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company). 

(e) Notice Concerning ISO Treatment. If this option is designated as an ISO in the Notice of Stock Option Grant, it ceases to
qualify for favorable tax treatment as an ISO to the extent it is exercised (i) more than three months after the date the Optionee ceases to be an Employee for any reason other than death or permanent and total disability (as defined in
Section 22(e)(3) of the Code), (ii) more than 12 months after the date the Optionee ceases to be an Employee by reason of such permanent and total disability or (iii) after the Optionee has been on a leave of absence for more than 90 days,
unless the Optionee’s reemployment rights are guaranteed by statute or by contract. 
 SECTION 7. RIGHT OF REPURCHASE. 

(a) Scope of Repurchase Right. Unless they have become vested in accordance with the Notice of Stock Option Grant and Subsection
(c) below, the Shares acquired under this Agreement initially shall be Restricted Shares and shall be subject to a right (but not an obligation) of repurchase by the Company. The Optionee shall not transfer, assign, encumber or otherwise
dispose of any Restricted Shares, except as provided in the following sentence. The Optionee may transfer Restricted Shares (i) by beneficiary designation, will or intestate succession or (ii) to the Optionee’s spouse, children or
grandchildren or to a trust established by the Optionee for the benefit of the Optionee or the Optionee’s spouse, children or grandchildren, provided in either case that the Transferee agrees in writing on a form prescribed by the Company to be
bound by all provisions of this Agreement. If the Optionee transfers any Restricted Shares, then this Section 7 shall apply to the Transferee to the same extent as to the Optionee. 

(b) Condition Precedent to Exercise. The Right of Repurchase shall be exercisable only during the 60-day period next following the
later of: 
 (i) The date when the Optionee’s Service terminates for any reason, with or without cause,
including (without limitation) death or disability; or 
 (ii) The date when this option was exercised by the
Optionee, the executors or administrators of the Optionee’s estate or any person who has acquired this option directly from the Optionee by bequest, inheritance or beneficiary designation. 

  
 4 








 (c) Lapse of Repurchase Right. The Right of Repurchase shall lapse with respect to
the Shares subject to this option in accordance with the vesting schedule set forth in the Notice of Stock Option Grant. The Right of Repurchase shall lapse and all of the remaining Restricted Shares shall become vested if (i) the Company is
subject to a Change in Control and (ii) the Right of Repurchase is not assigned to the entity that employs the Optionee immediately after the Change in Control or to its parent or subsidiary. Notwithstanding the foregoing, at a minimum, in the
event of a Change in Control, the Right of Repurchase shall lapse with respect to an additional number of Shares subject to this option, as if the Optionee served for an additional six (6) months of Service; in addition, at a minimum, in the
event that the Optionee is terminated from Service without Cause within six (6) months following a Change in Control, the Right of Repurchase shall lapse with respect to an additional number of Shares subject to this option, as if the Optionee
served an additional six (6) months of Service. 
 (d) Repurchase Cost. If the Company exercises the Right of
Repurchase, it shall pay the Optionee an amount equal to the Exercise Price for each of the Restricted Shares being repurchased. 
 (e) Exercise of Repurchase Right. The Right of Repurchase shall be exercisable only by written notice delivered to the Optionee prior to the expiration of the 60-day period specified in Subsection
(b) above. The notice shall set forth the date on which the repurchase is to be effected. Such date shall not be more than 30 days after the date of the notice. The certificate(s) representing the Restricted Shares to be repurchased shall,
prior to the close of business on the date specified for the repurchase, be delivered to the Company properly endorsed for transfer. The Company shall, concurrently with the receipt of such certificate(s), pay to the Optionee the purchase price
determined according to Subsection (d) above. Payment shall be made in cash or cash equivalents or by canceling indebtedness to the Company incurred by the Optionee in the purchase of the Restricted Shares. The Right of Repurchase shall
terminate with respect to any Restricted Shares for which it has not been timely exercised pursuant to this Subsection (e). 

(f) Additional Shares or Substituted Securities. In the event of the declaration of a stock dividend, the declaration of an
extraordinary dividend payable in a form other than stock, a spin-off, a stock split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities without receipt of
consideration, any new, substituted or additional securities or other property (including money paid other than as an ordinary cash dividend) which are by reason of such transaction distributed with respect to any Restricted Shares or into which
such Restricted Shares thereby become convertible shall immediately be subject to the Right of Repurchase. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number and/or class of the Restricted
Shares. Appropriate adjustments shall also, after each such transaction, be made to the price per share to be paid upon the exercise of the Right of Repurchase in order to reflect any change in the Company’s outstanding securities effected
without receipt of consideration therefor; provided, however, that the aggregate purchase price payable for the Restricted Shares shall remain the same. 
 (g) Termination of Rights as Stockholder. If the Company makes available, at the time and place and in the amount and form provided in this Agreement, the consideration for the Restricted Shares to
be repurchased in accordance with this Section 7, then after such time the 

  
 5 








 
person from whom such Restricted Shares are to be repurchased shall no longer have any rights as a holder of such Restricted Shares (other than the right to receive payment of such consideration
in accordance with this Agreement). Such Restricted Shares shall be deemed to have been repurchased in accordance with the applicable provisions hereof, whether or not the certificate(s) therefor have been delivered as required by this Agreement.

 (h) Escrow. Upon issuance, the certificates for Restricted Shares shall be deposited in escrow with the Company to be
held in accordance with the provisions of this Agreement. Any new, substituted or additional securities or other property described in Subsection (f) above shall immediately be delivered to the Company to be held in escrow, but only to the
extent the Shares are at the time Restricted Shares. All regular cash dividends on Restricted Shares (or other securities at the time held in escrow) shall be paid directly to the Optionee and shall not be held in escrow. Restricted Shares, together
with any other assets or securities held in escrow hereunder, shall be (i) surrendered to the Company for repurchase and cancellation upon the Company’s exercise of its Right of Repurchase or Right of First Refusal or (ii) released to
the Optionee upon the Optionee’s request to the extent the Shares are no longer Restricted Shares (but not more frequently than once every six months). In any event, all Shares which have vested (and any other vested assets and securities
attributable thereto) shall be released within 60 days after the earlier of (i) the Optionee’s cessation of Service or (ii) the lapse of the Right of First Refusal. 
 SECTION 8. RIGHT OF FIRST REFUSAL. 
 Optionee or Transferee hereby agrees
that the Shares acquired pursuant to this Agreement are subject to the Company’s Right of First Refusal, as set forth in the Company’s Bylaws. 
 SECTION 9. LEGALITY OF INITIAL ISSUANCE. 
 No Shares shall be issued upon
the exercise of this option unless and until the Company has determined that: 
 (a) It and the Optionee have taken any actions
required to register the Shares under the Securities Act or to perfect an exemption from the registration requirements thereof; 

(b) Any applicable listing requirement of any stock exchange on which Stock is listed has been satisfied; and 

(c) Any other applicable provision of state or federal law has been satisfied. 
 SECTION 10. NO REGISTRATION RIGHTS. 
 The Company may, but shall not be
obligated to, register or qualify the sale of Shares under the Securities Act or any other applicable law. The Company shall not be obligated to take any affirmative action in order to cause the sale of Shares under this Agreement to comply with any
law.

 SECTION 11. RESTRICTIONS ON TRANSFER. 

(a) Securities Law Restrictions. Regardless of whether the offering and sale of Shares under the Plan have been registered under
the Securities Act or have been registered or qualified under the securities laws of any state, the Company at its discretion may impose restrictions upon the sale, pledge or other transfer of such Shares (including the placement of appropriate
legends on stock certificates or the imposition of stop-transfer instructions) if, in the judgment of the Company, such restrictions are necessary or desirable in order to achieve compliance with the Securities Act, the securities laws of any state
or any other law, 
 (b) Market Stand-Off. In connection with any underwritten public offering by the Company of its
equity securities pursuant to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, the Optionee shall not directly or indirectly sell, make any short sale of, loan, hypothecate,
pledge, offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the sale of, or otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with respect to, any
Shares acquired under this Agreement without the prior written consent of the Company or its underwriters. Such restriction (the “Market Stand-Off’) shall be in effect for such period of time following the date of the final prospectus for

 VISTO CORPORATION 1996 STOCK
PLAN: 
 STOCK OPTION AGREEMENT 

SECTION 1. GRANT OF OPTION. 
 (a) Option. On the terms and conditions set forth in the Notice of Stock Option Grant and this Agreement, the Company grants to the Optionee on the Date of Grant the option to purchase at the
Exercise Price the number of Shares set forth in the Notice of Stock Option Grant. The Exercise Price is agreed to be at least 100% of the Fair Market Value per Share on the Date of Grant (110% of Fair Market Value if Section 3(b) of the Plan
applies). This option is intended to be an ISO or a Nonstatutory Option, as provided in the Notice of Stock Option Grant. 
 (b)
Stock Plan and Defined Terms. This option is granted pursuant to the Plan, a copy of which the Optionee acknowledges having received. The provisions of the Plan are incorporated into this Agreement by this reference. Capitalized terms are
defined in Section 14 of this Agreement. 
 SECTION 2. RIGHT TO EXERCISE. 

(a) Exercisability. Subject to Subsections (b) and (c) below and the other conditions set forth in this Agreement, all or
part of this option may be exercised prior to its expiration at the time or times set forth in the Notice of Stock Option Grant. Shares purchased by exercising this option may be subject to the Right of Repurchase under Section 7. 

(b) $100,000 Limitation. If this Option is designated as an ISO in the Notice of Stock Option Grant, then the Optionee’s
right to exercise this option shall be deferred to the extent (and only to the extent) that this option otherwise would not be treated as an ISO by reason of the $100,000 annual limitation under Section 422(d) of the Code, except that:

 (i) The Optionee’s right to exercise this option shall not be deferred with respect to that portion of
the Shares subject to this option whose Fair Market Value as of the Date of Grant exceeds $500,000; and 
 (ii)
The Optionee’s right to exercise this option shall no longer be deferred in the event that (A) a Change in Control occurs, (B) this option is not assumed 

  
 1 








 
by the surviving corporation or its parent and (C) the surviving corporation or its parent does not substitute its own option for this option. 

(c) Stockholder Approval. Any other provision of this Agreement notwithstanding, no portion of this option shall be exercisable at
any time prior to the approval of the Plan by the Company’s stockholders. 
 SECTION 3. NO TRANSFER OR ASSIGNMENT OF OPTION.

 Except as otherwise provided in this Agreement, this option and the rights and privileges conferred hereby shall not be
sold, pledged or otherwise transferred (whether by operation of law or otherwise) and shall not be subject to sale under execution, attachment, levy or similar process. 
 SECTION 4. EXERCISE PROCEDURES. 
 (a) Notice of Exercise. The
Optionee or the Optionee’s representative may exercise this option by giving written notice to the Company pursuant to Section 13(c). The notice shall specify the election to exercise this option, the number of Shares for which it is being
exercised and the form of payment. The notice shall be signed by the person exercising this option. In the event that this option is being exercised by the representative of the Optionee, the notice shall be accompanied by proof (satisfactory to the
Company) of the representative’s right to exercise this option. The Optionee or the Optionee’s representative shall deliver to the Company, at the time of giving the notice, payment in a form permissible under Section 5 for the full
amount of the Purchase Price. 
 (b) Issuance of Shares. After receiving a proper notice of exercise, the Company shall
cause to be issued a certificate or certificates for the Shares as to which this option has been exercised, registered in the name of the person exercising this option (or in the names of such person and his or her spouse as community property or as
joint tenants with right of survivorship). The Company shall cause such certificate or certificates to be deposited in escrow or delivered to or upon the order of the person exercising this option. 

(c) Withholding Taxes. In the event that the Company determines that it is required to withhold any tax as a result of the
exercise of this option, the Optionee, as a condition to the exercise of this option, shall make arrangements satisfactory to the Company to enable it to satisfy all withholding requirements. The Optionee shall also make arrangements satisfactory to
the Company to enable it to satisfy any withholding requirements that may arise in connection with the vesting or disposition of Shares purchased by exercising this option. 
 SECTION 5. PAYMENT FOR STOCK. 
 (a) Cash. All or part of the Purchase
Price may be paid in cash or cash equivalents. 

  
 2 








 (b) Surrender of Stock. All or part of the Purchase Price may be paid by the
surrender of Shares in good form for transfer. Such Shares must have a fair market value (as determined by the Board of Directors) on the date of exercise of this option which, together with any amount paid in another form permissible under this
Section 5, is equal to the Purchase Price. The Optionee shall not surrender Shares in payment of the Exercise Price if such surrender would cause the Company to recognize compensation expense with respect to the option for financial reporting
purposes. 
 (c) Promissory Note. All or a portion of the Purchase Price may be paid with a full-recourse promissory
note. The par value of the Shares, if newly issued, shall be paid in cash or cash equivalents. The Shares acquired by exercising this option shall be pledged as security for payment of the principal amount of the promissory note and interest
thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate, if any, required to avoid (i) the imputation of additional interest under the Code and (ii) variable accounting under the
applicable guidelines issued by the Financial Accounting Standards Board. Subject to the foregoing, the Board of Directors (at its sole discretion) shall specify the term, interest rate, amortization requirements, if any, and other provisions of
such note. 
 (d) Exercise/Sale. If Stock is publicly traded, all or part of the Purchase Price and any withholding taxes
may be paid by the delivery (on a form prescribed by the Company) of an irrevocable direction to a securities broker approved by the Company to sell Shares and to deliver all or part of the sales proceeds to the Company. 

(e) Exercise/Pledge. If Stock is publicly traded, all or part of the Purchase Price and any withholding taxes may be paid by the
delivery (on a form prescribed by the Company) of an irrevocable direction to pledge Shares to a securities broker or lender approved by the Company, as security for a loan, and to deliver all or part of the loan proceeds to the Company. 

SECTION 6. TERM AND EXPIRATION. 
 (a) Basic Term. This option shall in any event expire on the expiration date set forth in the Notice of Stock Option Grant, which date is 10 years after the Date of Grant (five years after the Date
of Grant if this option is designated as an ISO in the Notice of Stock Option Grant and Section 3(b) of the Plan applies). 

(b) Termination of Service (Except by Death). If the Optionee’s Service terminates for any reason other than death, then this
option shall expire on the earliest of the following occasions: 
 (i) The expiration date determined pursuant
to Subsection (a) above; 
 (ii) The date three months after the termination of the Optionee’s Service
for any reason other than Disability; or 
 (iii) The date six months after the termination of the
Optionee’s Service by reason of Disability. 

  
 3 








 The Optionee may exercise all or part of this option at any time before its expiration under the preceding
sentence, but only to the extent that this option had become exercisable before the Optionee’s Service terminated. When the Optionee’s Service terminates, this option shall expire immediately with respect to the number of Shares for which
this option is not yet exercisable and with respect to any Restricted Shares. In the event that the Optionee dies after termination of Service but before the expiration of this option, all or part of this option may be exercised (prior to
expiration) by the executors or administrators of the Optionee’s estate or by any person who has acquired this option directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that this option had
become exercisable before the Optionee’s Service terminated. 
 (c) Death of the Optionee. If the Optionee dies
while in Service, then this option shall expire on the earlier of the following dates: 
 (i) The expiration
date determined pursuant to Subsection (a) above; or 
 (ii) The date 12 months after the Optionee’s
death. 
 All or part of this option may be exercised at any time before its expiration under the preceding sentence by the executors or
administrators of the Optionee’s estate or by any person who has acquired this option directly from the Optionee by beneficiary designation, bequest or inheritance, but only to the extent that this option had become exercisable before the
Optionee’s death. When the Optionee dies, this option shall expire immediately with respect to the number of Shares for which this option is not yet exercisable and with respect to any Restricted Shares. 

(d) Leaves of Absence. For any purpose under this Agreement, Service shall be deemed to continue while the Optionee is on a bona
fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for such purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company). 

(e) Notice Concerning ISO Treatment. If this option is designated as an ISO in the Notice of Stock Option Grant, it ceases to
qualify for favorable tax treatment as an ISO to the extent it is exercised (i) more than three months after the date the Optionee ceases to be an Employee for any reason other than death or permanent and total disability (as defined in
Section 22(e)(3) of the Code), (ii) more than 12 months after the date the Optionee ceases to be an Employee by reason of such permanent and total disability or (iii) after the Optionee has been on a leave of absence for more than 90
days, unless the Optionee’s reemployment rights are guaranteed by statute or by contract. 
 SECTION 7. RIGHT OF REPURCHASE.

 (a) Scope of Repurchase Right. Unless they have become vested in accordance with the Notice of Stock Option Grant
and Subsection (c) below, the Shares acquired under this Agreement initially shall be Restricted Shares and shall be subject to a right (but not an obligation) of repurchase by the Company. The Optionee shall not transfer, assign, encumber or


  
 4 








 
otherwise dispose of any Restricted Shares, except as provided in the following sentence. The Optionee may transfer Restricted Shares (i) by beneficiary designation, will or intestate
succession or (ii) to the Optionee’s spouse, children or grandchildren or to a trust established by the Optionee for the benefit of the Optionee or the Optionee’s spouse, children or grandchildren, provided in either case that the
Transferee agrees in writing on a form prescribed by the Company to be bound by all provisions of this Agreement. If the Optionee transfers any Restricted Shares, then this Section 7 shall apply to the Transferee to the same extent as to the
Optionee. 
 (b) Condition Precedent to Exercise. The Right of Repurchase shall be exercisable only during the 60-day
period next following the later of: 
 (i) The date when the Optionee’s Service terminates for any reason,
with or without cause, including (without limitation) death or disability; or 
 (ii) The date when this option
was exercised by the Optionee, the executors or administrators of the Optionee’s estate or any person who has acquired this option directly from the Optionee by bequest, inheritance or beneficiary designation. 

(c) Lapse of Repurchase Right. The Right of Repurchase shall lapse with respect to the Shares subject to this option in accordance
with the vesting schedule set forth in the Notice of Stock Option Grant. The Right of Repurchase shall lapse and all of the remaining Restricted Shares shall become vested if (i) the Company is subject to a Change in Control before the
Optionee’s Service terminates and (ii) the Right of Repurchase is not assigned to the entity that employs the Optionee immediately after the Change in Control or to its parent or subsidiary or (iii) the Optionee is subject to an
Involuntary Termination within twelve (12) months following the Change in Control. 
 (d) Repurchase Cost. If the
Company exercises the Right of Repurchase, it shall pay the Optionee an amount equal to the Exercise Price for each of the Restricted Shares being repurchased. 
 (e) Exercise of Repurchase Right. The Right of Repurchase shall be exercisable only by written notice delivered to the Optionee prior to the expiration of the 60-day period specified in Subsection
(b) above. The notice shall set forth the date on which the repurchase is to be effected. Such date shall not be more than 30 days after the date of the notice. The certificate(s) representing the Restricted Shares to be repurchased shall,
prior to the close of business on the date specified for the repurchase, be delivered to the Company properly endorsed for transfer. The Company shall, concurrently with the receipt of such certificate(s), pay to the Optionee the purchase price
determined according to Subsection (d) above. Payment shall be made in cash or cash equivalents or by canceling indebtedness to the Company incurred by the Optionee in the purchase of the Restricted Shares. The Right of Repurchase shall
terminate with respect to any Restricted Shares for which it has not been timely exercised pursuant to this Subsection (e). 

  
 5 








 (f) Additional Shares or Substituted Securities. In the event of the declaration of a
stock dividend, the declaration of an extraordinary dividend payable in a form other than stock, a spin-off, a stock split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding
securities without receipt of consideration, any new, substituted or additional securities or other property (including money paid other than as an ordinary cash dividend) which are by reason of such transaction distributed with respect to any
Restricted Shares or into which such Restricted Shares thereby become convertible shall immediately be subject to the Right of Repurchase. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number
and/or class of the Restricted Shares. Appropriate adjustments shall also, after each such transaction, be made to the price per share to be paid upon the exercise of the Right of Repurchase in order to reflect any change in the Company’s
outstanding securities effected without receipt of consideration therefor; provided, however, that the aggregate purchase price payable for the Restricted Shares shall remain the same. 

(g) Termination of Rights as Stockholder. If the Company makes available, at the time and place and in the amount and form
provided in this Agreement, the consideration for the Restricted Shares to be repurchased in accordance with this Section 7, then after such time the person from whom such Restricted Shares are to be repurchased shall no longer have any rights
as a holder of such Restricted Shares (other than the right to receive payment of such consideration in accordance with this Agreement). Such Restricted Shares shall be deemed to have been repurchased in accordance with the applicable provisions
hereof, whether or not the certificate(s) therefor have been delivered as required by this Agreement. 
 (h) Escrow. Upon
issuance, the certificates for Restricted Shares shall be deposited in escrow with the Company to be held in accordance with the provisions of this Agreement. Any new, substituted or additional securities or other property described in Subsection
(f) above shall immediately be delivered to the Company to be held in escrow, but only to the extent the Shares are at the time Restricted Shares. All regular cash dividends on Restricted Shares (or other securities at the time held in escrow)
shall be paid directly to the Optionee and shall not be held in escrow. Restricted Shares, together with any other assets or securities held in escrow hereunder, shall be (i) surrendered to the Company for repurchase and cancellation upon the
Company’s exercise of its Right of Repurchase or Right of First Refusal or (ii) released to the Optionee upon the Optionee’s request to the extent the Shares are no longer Restricted Shares (but not more frequently than once every six
months). In any event, all Shares which have vested (and any other vested assets and securities attributable thereto) shall be released within 60 days after the earlier of (i) the Optionee’s cessation of Service or (ii) the lapse of
the Right of First Refusal. 
 SECTION 8. RIGHT OF FIRST REFUSAL. 

Optionee or Transferee hereby agrees that the Shares acquired pursuant to this Agreement are subject to the Company’s Right of First
Refusal, as set forth in the Company’s Bylaws.

the registration requirements thereof; 
 (b) Any applicable listing requirement of any stock exchange on which Stock is listed
has been satisfied; and

action in order to cause the sale of Shares under this Agreement to comply with any law. 
 SECTION 11. RESTRICTIONS ON TRANSFER.

 (a) Securities Law Restrictions. Regardless of whether the offering and sale of Shares under the Plan have been
registered under the Securities Act or have been registered or qualified under the securities laws of any state, the Company at its discretion may impose restrictions upon the sale, pledge or other transfer of such Shares (including the placement of
appropriate legends on stock certificates or the imposition of stop-transfer instructions) if, in the judgment of the Company, such restrictions are necessary or desirable in order to achieve compliance with the Securities Act, the securities laws
of any state or any other law. 
 (b) Market Stand-Off. In connection with any underwritten public offering by the
Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, the Optionee shall not directly or indirectly sell, make any short sale of, loan,
hypothecate, pledge, offer, grant or sell any option or other contract for the purchase of, purchase any option or other contract for the sale of, or otherwise dispose of or transfer, or agree to engage in any of the foregoing transactions with
respect to, any Shares acquired under this Agreement without the prior written consent of the Company or its underwriters. Such restriction (the “Market Stand-Off”) shall be in effect for such period of time following the date of the final
prospectus for the offering as may be requested by the Company or such underwriters. In no event, however, shall such period exceed 180 days. The Market Stand-Off shall in any event terminate two years after the date of the Company’s initial
public offering. In the event of the declaration of a stock dividend, a spin-off, a stock split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding securities without receipt of
consideration, any new, substituted or additional securities which are by reason of such transaction distributed with respect to any Shares subject to the Market Stand-Off, or into which such Shares thereby become


  
 7 








 
convertible, shall immediately be subject to the Market Stand-Off. In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with respect to the Shares acquired
under this Agreement until the end of the applicable stand-off period. The Company’s underwriters shall be beneficiaries of the agreement set forth in this Subsection (b). This Subsection (b) shall not apply to Shares registered in the
public offering under the Securities Act, and the Optionee shall be subject to this Subsection (b) only if the directors and officers of the Company are subject to similar arrangements. 

(c) Investment Intent at Grant. The Optionee represents and agrees that the Shares to be acquired upon exercising this option will
be acquired for investment, and not with a view to the sale or distribution thereof. 
 (d) Investment Intent at
Exercise. In the event that the sale of Shares under the Plan is not registered under the Securities Act but an exemption is available which requires an investment representation or other representation, the Optionee shall represent and agree at
the time of exercise that the Shares being acquired upon exercising this option are being acquired for investment, and not with a view to the sale or distribution thereof, and shall make such other representations as are deemed necessary or
appropriate by the Company and its counsel. 
 (e) Legends. All certificates evidencing Shares purchased under this
Agreement shall bear the following legend: 
 “THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED, TRANSFERRED,
ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN COMPLIANCE WITH THE TERMS OF A WRITTEN AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR THE PREDECESSOR IN INTEREST TO THE SHARES). SUCH AGREEMENT GRANTS TO THE COMPANY
CERTAIN RIGHTS OF FIRST REFUSAL UPON AN ATTEMPTED TRANSFER OF THE SHARES AND CERTAIN REPURCHASE RIGHTS UPON TERMINATION OF SERVICE WITH THE COMPANY. THE SECRETARY OF THE COMPANY WILL UPON WRITTEN REQUEST FURNISH A COPY OF SUCH AGREEMENT TO THE
HOLDER HEREOF WITHOUT CHARGE.” 
 All certificates evidencing Shares purchased under this Agreement in an unregistered transaction shall
bear the following legend (and such other restrictive legends as are required or deemed advisable under the provisions of any applicable law): 
 “THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF
UNDER SUCH ACT OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.” 

  
 8 








 (f) Removal of Legends. If, in the opinion of the Company and its counsel, any legend
placed on a stock certificate representing Shares sold under this Agreement is no longer required, the holder of such certificate shall be entitled to exchange such certificate for a certificate representing the same number of Shares but without
such legend. 
 (g) Administration. Any determination by the Company and its counsel in connection with any of the
matters set forth in this Section 11 shall be conclusive and binding on the Optionee and all other persons. 
 SECTION 12. ADJUSTMENT OF
SHARES. 
 In the event of any transaction described in Section 8(a) of the Plan, the terms of this option (including,
without limitation, the number and kind of Shares subject to this option and the Exercise Price) shall be adjusted as set forth in Section 8(a) of the Plan, In the event that the Company is a party to a merger or consolidation, this option
shall be subject to the agreement of merger or consolidation, as provided in Section 8(b) of the Plan. 
 SECTION 13. MISCELLANEOUS
PROVISIONS.
