 EXHIBIT 4.6 
 CALLVISION, INC. 1999 STOCK PLAN 
 SECTION 1. ESTABLISHMENT AND PURPOSE. 
 The purpose of the Plan is to offer selected individuals 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
Shareholders. An individual 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 the grant of an ISO unless (i) the
Exercise Price is at least 110% of the Fair Market Value of a Share on the date of grant and (ii) 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. 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 4,000,000 Shares, subject to adjustment pursuant to Section 8. 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 pursuant to any forfeiture provision, right of repurchase or right of first refusal, such Shares shall again be available for the purposes of the Plan, except that the aggregate number of Shares which may be issued upon the exercise of ISOs
shall in no event exceed 4,000,000 Shares (subject to adjustment pursuant to Section 8). 
 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 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. 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. 
 (f) Accelerated Vesting. Unless the applicable Stock Purchase Agreement provides otherwise,
and except as set forth below, any right to repurchase a Purchaser’s Shares at the original Purchase Price (if any) upon termination of the Purchaser’s Service shall lapse and all of such Shares shall become vested if: 
 (i) The Company is subject to a Change in Control before the Purchaser’s Service terminates; and 
 (ii) Either (A) the repurchase right is not assigned to the entity that employs the Purchaser immediately after the Change in Control
or to its parent or subsidiary or (B) the Purchaser is subject to an Involuntary Termination within 12 months following such Change in Control. 

 A Stock Purchase Agreement may also provide for accelerated vesting in the event of the Optionee’s
death or disability or other events. 
 Notwithstanding the above, if the Company and the other party to the transaction constituting a
Change in Control agree that such transaction is to be treated as a “pooling of interests” for financial reporting purposes, and if such transaction in fact is so treated, then the acceleration of vesting shall not occur to the extent that
the Company’s independent public accountants and such other party’s independent public accountants separately determine in good faith that such acceleration would preclude the use of “pooling of interests” accounting. 

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. 
 (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). Subject to the preceding sentence, the Exercise Price under an 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. The exercisability provisions of a Stock Option Agreement shall be determined by the Board of Directors at its sole discretion. 
 (f) Accelerated Exercisability. Unless the applicable Stock Option Agreement provides otherwise, all of an Optionee’s Options shall become exercisable in full if: 
 (i) The Company is subject to a Change in Control before the Optionee’s Service terminates; and 
 (ii) Either (A) such Options do not remain outstanding, such Options are not assumed by the surviving corporation or its parent, and
the surviving corporation or its parent does not substitute options with substantially the same terms for such Options or (B) the Optionee is subject to an Involuntary Termination within 12 months following such Change in Control. 

 Notwithstanding the above, if the Company and the other party to the transaction constituting a Change in Control agree
that such transaction is to be treated as a “pooling of interests” for financial reporting purposes, and if such transaction in fact is so treated, then the acceleration of exercisability shall not occur to the extent that the
Company’s independent public accountants and such other party’s independent public accountants separately determine in good faith that such acceleration would preclude the use of “pooling of interests” accounting. 
 (g) 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 in
the case of an ISO 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. A Stock Option Agreement may provide for expiration
prior to the end of its term in the event of the termination of the Optionee’s Service or death. 
 (h) 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. 
 (i) No Rights as a Shareholder. An Optionee, or a transferee of an Optionee, shall have no rights as a
shareholder 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. 
 (j) 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. 
 (k) Restrictions on Transfer of Shares. Any Shares issued upon exercise of an Option shall be subject to such special forfeiture conditions,
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. 
 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, all or any part
of the Exercise Price may be paid by surrendering, or attesting to the ownership of, Shares that are already owned by the Optionee. Such Shares shall be surrendered to the Company in good form for transfer and shall be valued at their Fair Market
Value on the date when the Option is exercised. The Optionee shall not surrender, or attest to the ownership of, Shares in payment of the Exercise Price if such action would cause the Company to recognize compensation expense (or additional
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. At the discretion of the Board of Directors, Shares may also be awarded under the Plan in consideration of services to be rendered to the
Company, a Parent or a Subsidiary after the award, except that the par value of such Shares, if newly issued, shall be paid in cash or cash equivalents. 
 (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. However, the par value of the Shares shall be paid in cash or cash equivalents. 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 the imputation of additional interest under the Code. 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. 
 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, 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 combination or consolidation of the outstanding Stock into a lesser number of Shares, a recapitalization, a
spin-off, a reclassification or a similar occurrence, the Board of Directors shall 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, outstanding Options shall be subject to the agreement of merger or consolidation. Such agreement, without the Optionees’ consent, may provide for: 
 (i) The continuation of such outstanding Options by the Company (if the Company is the surviving corporation); 
 (ii) The assumption of the Plan and such outstanding Options by the surviving corporation or its parent; 
 (iii) The substitution by the surviving corporation or its parent of options with substantially the same terms for such outstanding
Options; or 

 (iv) The cancellation of each outstanding Option after payment to the Optionee of an
amount in cash or cash equivalents equal to (A) the Fair Market Value of the Shares subject to such Option at the time of the merger or consolidation minus (B) the Exercise Price of the Shares subject to such Option. 
 (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. 
 SECTION 9. SECURITIES LAW REQUIREMENTS. 
 Shares shall not be issued under the Plan unless the issuance and delivery of such Shares comply with (or are exempt from) all applicable requirements of
law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state securities laws and regulations, and the regulations of any stock exchange or other securities market on which the
Company’s securities may then be traded. 
 SECTION 10. No Retention Rights. 
 Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Purchaser or Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are hereby
expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause. 
 SECTION 11. DURATION AND AMENDMENTS.

 (a) Term of the Plan. The Plan, as set forth herein, shall become effective on the date of its adoption by the Board of
Directors, subject to the approval of the Company’s shareholders. In the event that the shareholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, any grants of Options or sales or awards of Shares that
have already occurred shall be rescinded, and no additional grants, sales or awards shall be made thereafter under the Plan. The Plan shall terminate automatically 10 years after its adoption by the Board of Directors and 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 shareholders. Shareholder approval shall not be required for any other amendment of the Plan. 
 (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 affect any Share previously issued or any Option previously granted under the Plan.

 EXHIBIT 4.7 
 RETAIL SOLUTIONS INTERNATIONAL, INC. 
 2001 STOCK PLAN 
 1. Purpose.  
 The purpose of the Retail Solutions
International, Inc. 2001 Stock Plan (the “Plan”) is to encourage key employees of Retail Solutions International, Inc., a Delaware corporation (the “Company”), and of any present or future parent or subsidiary of the Company
(collectively, “Related Corporations”) and other individuals who render services to the Company or a Related Corporation, by providing opportunities to participate in the ownership of the Company and its future growth through (a) the
grant of options which qualify as “incentive stock options” (“ISOs”) under Section 422(b) of the Internal Revenue Code of 1986, as amended (the “Code”); (b) the grant of options which do not qualify as ISOs
(“Non-Qualified Options”); (c) awards of stock in the Company (“Awards”); and (d) opportunities to make direct purchases of stock in the Company (“Purchases”). Both ISOs and Non-Qualified Options are referred
to hereafter individually as an “Option” and collectively as “Options.” Options, Awards and authorizations to make Purchases are referred to hereafter collectively as “Stock Rights.” As used herein, the terms
“parent” and “subsidiary” mean “parent corporation” and “subsidiary corporation”, respectively, as those terms are defined in Section 424 of the Code. 
 2. Administration of the Plan. 
 A. Board or
Committee Administration. The Plan shall be administered by the Board of Directors of the Company (the “Board”) or, subject to paragraph 2(C) (relating to compliance with Section 162(m) of the Code), by a committee appointed by
the Board (the “Committee”). Hereinafter, all references in this Plan to the “Committee” shall mean the Board if no Committee has been appointed. Subject to ratification of the grant or authorization of each Stock Right by the
Board (if so required by applicable state law), and subject to the terms of the Plan, the Committee shall have the authority to (i) determine to whom (from among the class of employees eligible under paragraph 3 to receive ISOs) ISOs shall be
granted, and to whom (from among the class of individuals and entities eligible under paragraph 3 to receive Non-Qualified Options and Awards and to make Purchases) Non-Qualified Options, Awards and authorizations to make Purchases may be granted;
(ii) determine the time or times at which Options or Awards shall be granted or Purchases made; (iii) determine the purchase price of shares subject to each Option or Purchase, which prices shall not be less than the minimum price
specified in paragraph 6 in the case of ISOs; (iv) determine whether each Option granted shall be an ISO or a Non-Qualified Option; (v) determine (subject to paragraph 7) the time or times when each Option shall become exercisable and the
duration of the exercise period; (vi) extend the period during which outstanding Options may be exercised; (vii) determine whether restrictions such as repurchase options are to be imposed on shares subject to Options, Awards and Purchases
and the nature of such restrictions, if any, and (viii) interpret the Plan and prescribe and rescind rules and regulations relating to it. If the Committee determines to issue a Non-Qualified Option, it shall take whatever actions it deems
necessary, under Section 422 of the Code and the regulations promulgated thereunder, to ensure that such Option is not treated as an ISO. The interpretation and construction by the Committee of any provisions of the Plan or of any Stock Right
granted under it shall be final unless otherwise determined by the Board. The Committee may from time to time adopt such rules and regulations for carrying out the Plan as it may deem advisable. No member of the Board or the Committee shall be
liable for any action or determination made in good faith with respect to the Plan or any Stock Right granted under it. 
 B. Committee
Actions. The Committee may select one of its members as its chairman, and shall hold meetings at such time and places as it may determine. A majority of the Committee shall constitute a quorum and acts of a majority of the members of the
Committee at a meeting at which a quorum is present, or acts reduced to or approved in writing by all the members of the Committee (if consistent with applicable state law), shall be the valid acts of the Committee. From time to time the 

 Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without
cause) and appoint new members in substitution therefor, fill vacancies however caused, or remove all members of the Committee and thereafter directly administer the Plan. 
 C. Performance-Based Compensation. The Board, in its discretion, may take such action as may be necessary to ensure that Stock Rights granted
under the Plan qualify as “qualified performance-based compensation” within the meaning of Section 162(m) of the Code and applicable regulations promulgated thereunder (“Performance-Based Compensation”). Such action may
include, in the Board’s discretion, some or all of the following (i) if the Board determines that Stock Rights granted under the Plan generally shall constitute Performance-Based Compensation, the Plan shall be administered, to the extent
required for such Stock Rights to constitute Performance-Based Compensation, by a Committee consisting solely of two or more “outside directors” (as defined in applicable regulations promulgated under Section 162(m) of the Code),
(ii) if any Non-Qualified Options with an exercise price less than the fair market value per share of the Common Stock are granted under the Plan and the Board determines that such Options should constitute Performance Based Compensation, such
options shall be made exercisable only upon the attainment of a pre-established, objective performance goal established by the Committee, and such grant shall be submitted for, and shall be contingent upon shareholder approval and (iii) Stock
Rights granted under the Plan may be subject to such other terms and conditions as are necessary for compensation recognized in connection with the exercise or disposition of such Stock Right or the disposition of Common Stock acquired pursuant to
such Stock Right, to constitute Performance-Based Compensation. 
 3. Eligible Employees and Others. 
 ISOs may be granted only to employees of the Company or any Related Corporation. Non-Qualified Options, Awards and authorizations to make Purchases may be
granted to any employee, director or consultant of the Company or any Related Corporation. The Committee may also take into consideration a recipient’s individual circumstances in determining whether to grant a Stock Right. The granting of any
Stock Right to any individual or entity shall neither entitle that individual or entity to, nor disqualify such individual or entity from, participation in any other grant of Stock Rights. 
 4. Stock. 
 The stock subject to Stock Rights shall be
authorized but unissued shares of the Company’s Common Stock, par value $0.001 per share (“Common Stock”), or shares of Common Stock reacquired by the Company in any manner. The aggregate number of shares which may be issued pursuant
to the Plan is 150,000 shares of Common Stock, subject to adjustment as provided in paragraph 13. No employee of the Company or any Related Corporation may be granted Options to acquire, in the aggregate, more than 125,000 shares of Common Stock
under the Plan, subject to adjustment as provided in paragraph 13. If any Option granted under the Plan shall expire or terminate for any reason without having been exercised in full or shall cease for any reason to be exercisable in whole or in
part or shall be repurchased by the Company, the unpurchased shares of Common Stock subject to such Option shall again be available for grants of Stock Rights under the Plan. 
 5. Granting of Stock Rights. 
 Stock Rights may be granted under the Plan at any time on or after
December 12, 2001 and prior to December 12, 2011. The date of grant of a Stock Right under the Plan will be the date specified by the Committee at the time it grants the Stock Right; provided, however, that such date shall not be prior to
the date on which the Committee acts to approve the grant. 

 6. Minimum Option Price; ISO Limitations. 
 A. Price For Non-Qualified Options, Awards and Purchases. Subject to paragraph 2(C) (relating to compliance with Section 162(m) of the Code),
the exercise price per share specified in the agreement relating to each Non-Qualified Option granted, and the purchase price per share of stock granted in any Award or authorized as a Purchase, under the Plan shall be determined by the Committee.

 B. Price For ISOs. The exercise price per share specified in the agreement relating to each ISO granted under the Plan shall not be
less than the fair market value per share of the Common Stock on the date of such grant. In the case of an ISO to be granted to an employee owning stock possessing more than ten percent (10%) of the total combined voting power of all classes of
stock of the Company or any Related Corporation, the price per share specified in the agreement relating to such ISO shall not be less than one hundred ten percent (110%) of the fair market value per share of the Common Stock on the date of
grant. For purposes of determining stock ownership under this paragraph, the rules of Section 424(d) of the Code shall apply. 
 C.
$100,000 Annual Limitation On ISO Vesting. Each eligible employee may be granted Options treated as ISOs only to the extent that, in the aggregate under this Plan and all incentive stock option plans of the Company and any Related
Corporation, ISOs do not become exercisable for the first time by such employee during any calendar year with respect to stock having a fair market value (determined at the time the ISOs were granted) in excess of $100,000. The Company intends to
designate any Options granted in excess of such limitation as Non-Qualified Options, and the Company shall issue separate certificates to the optionee with respect to Options that are Non-Qualified Options and Options that are ISOs. 
 D. Determination of Fair Market Value. If, at the time an Option is granted under the Plan, the Company’s Common Stock is publicly traded,
“fair market value” shall be determined as of the date of grant or, if the prices or quotes discussed in this sentence are unavailable for such date, the last business day for which such prices or quotes are available prior to the date of
grant and shall mean (i) the average (on that date) of the high and low prices of the Common Stock on the principal national securities exchange on which the Common Stock is traded, if the Common Stock is then traded on a national securities
exchange; or (ii) the last reported sale price (on that date) of the Common Stock on the Nasdaq National Market, if the Common Stock is not then traded on a national securities exchange; or (iii) the closing bid price (or average of bid
prices) last quoted (on that date) by an established quotation service for over-the-counter securities, if the Common Stock is not reported on the Nasdaq National Market. If the Common Stock is not publicly traded at the time an Option is granted
under the Plan, “fair market value” shall mean the fair value of the Common Stock as determined by the Committee after taking into consideration all factors which it deems appropriate, including, without limitation, recent sale and offer
prices of the Common Stock in private transactions negotiated at arm’s length. 
 7. Option Duration. 
 Subject to earlier termination as provided in paragraphs 9 and 10 or in the agreement relating to such Option, each Option shall expire on the date
specified by the Committee, but not more than (i) ten years from the date of grant in the case of Options generally and (ii) five years from the date of grant in the case of ISOs granted to an employee owning stock possessing more than ten
percent (10%) of the total combined voting power of all classes of stock of the Company or any Related Corporation, as determined under paragraph 6(B). Subject to earlier termination as provided in paragraphs 9 and 10, the term of each ISO
shall be the term set forth in the original instrument granting such ISO, except with respect to any part of such ISO that is converted into a Non-Qualified Option pursuant to paragraph 16. 

 8. Exercise of Option. 
 Subject to the provisions of paragraphs 9 through 12, each Option granted under the Plan shall be exercisable as follows: 
 A. Vesting. The Option shall either be fully exercisable on the date of grant or shall become exercisable thereafter in such installments as the Committee may specify. 
 B. Full Vesting Of Installments. Once an installment becomes exercisable, it shall remain exercisable until expiration or termination of the
Option, unless otherwise specified by the Committee. 
 C. Partial Exercise. Each Option or installment may be exercised at any time
or from time to time, in whole or in part, for up to the total number of shares with respect to which it is then exercisable. 
 D.
Acceleration of Vesting. The Committee shall have the right to accelerate the date that any installment of any Option becomes exercisable; provided that the Committee shall not, without the consent of an optionee, accelerate the permitted
exercise date of any installment of any Option granted to any employee as an ISO (and not previously converted into a Non-Qualified Option pursuant to paragraph 16) if such acceleration would violate the annual vesting limitation contained in
Section 422(d) of the Code, as described in paragraph 6(C). 
 9. Termination Of Employment. 
 Unless otherwise specified in the agreement relating to such ISO, if an ISO optionee ceases to be employed by the Company and all Related Corporations
other than by reason of death or disability as defined in paragraph 10, no further installments of his or her ISOs shall become exercisable, and his or her ISOs shall terminate on the earlier of (a) ninety (90) days after the (date of
termination of his or her employment, or (b) their specified expiration dates, except to the extent that such ISOs (or unexercised installments thereof) have been converted into Non-Qualified Options pursuant to paragraph 16. For purposes of
this paragraph 9, employment shall be considered as continuing uninterrupted during any bona fide leave of absence (such as those attributable to illness, military obligations or governmental service) provided that the period of such leave does not
exceed ninety (90) days or, if longer, any period during which such optionee’s right to reemployment is guaranteed by statute or by contract. A bona fide leave of absence with the written approval of the Committee shall not be considered
an interruption of employment under this paragraph 9, provided that such written approval contractually obligates the Company or any Related Corporation to continue the employment of the optionee after the approved period of absence. ISOs granted
under the Plan shall not be affected by any change of employment within or among the Company and Related Corporations, so long as the optionee continues to be an employee of the Company or any Related Corporation. Nothing in the Plan shall be deemed
to give any grantee of any Stock Right the right to be retained in employment or other service by the Company or any Related Corporation for any period of time. 
 10. Death; Disability. 
 A. Death. If an ISO optionee ceases to be employed by the Company and all Related
Corporations by reason of his or her death, any ISO owned by such optionee may be exercised, to the extent otherwise exercisable on the date of death, by the estate, personal representative or beneficiary who has acquired the ISO by will or by the
laws of descent and distribution, until the earlier of (i) the specified expiration date of the ISO or (ii) one hundred eighty (180) days from the date of the optionee’s death. 
 B. Disability. If an ISO optionee ceases to be employed by the Company and all Related Corporations by reason of his or her disability, such
optionee shall have the right to exercise any ISO held by him or her on the date of termination of employment, for the number of shares for which he or she 

 could have exercised it on that date, until the earlier of (i) the specified expiration date of the ISO or
(ii) one hundred eighty (180) days from the date of the termination of the optionee’s employment. For the purposes of the Plan, the term “disability” shall mean “permanent and total disability” as defined in
Section 22(e)(3) of the Code or any successor statute. 
 11. Assignability. 
 No ISO shall be assignable or transferable by the optionee except by will or by the laws of descent and distribution, and during the lifetime of the
optionee shall be exercisable only by such optionee. Stock Rights other than ISOs shall be transferable to the extent set forth in the agreement relating to such Stock Right. 
 12. Terms and Conditions Of Options. 
 Options shall be evidenced by instruments (which need not be
identical) in such forms as the Committee may from time to time approve. Such instruments shall conform to the terms and conditions set forth in paragraphs 6 through 11 hereof and may contain such other provisions as the Committee deems advisable
which are not inconsistent with the Plan, including restrictions applicable to shares of Common Stock issuable upon exercise of Options. The Committee may specify that any Non-Qualified Option shall be subject to the restrictions set forth herein
with respect to ISOs, or to such other termination and cancellation provisions as the Committee may determine. The Committee may from time to time confer authority and responsibility on one or more of its own members and/or one or more officers of
the Company to execute and deliver such instruments. The proper officers of the Company are authorized and directed to take any and all action necessary or advisable from time to time to carry out the terms of such instruments. 
 13. Adjustments. 
 Upon the occurrence of any of the
following events, an optionee’s rights with respect to Options granted to such optionee hereunder shall be adjusted as hereinafter provided, unless otherwise specifically provided in the written agreement between the optionee and the Company
relating to such Option: 
 13.1. Stock Dividends And Stock Splits. If the Common Stock shall be subdivided or combined into a greater
or smaller number of shares or if the Company shall issue any shares of Common Stock as a stock dividend on its outstanding Common Stock, the number of shares of Common Stock deliverable upon the exercise of Options shall be appropriately increased
or decreased proportionately, and appropriate adjustments shall be made in the purchase price per share to reflect such subdivision, combination or stock dividend. 
 13.2. Consolidations or Mergers. If the Company is to be consolidated with or acquired by another entity in a merger or other reorganization in which the holders of the outstanding voting stock of the Company
immediately preceding the consummation of such event, shall, immediately following such event, hold, as a group, less than a majority of the voting securities of the surviving or successor entity, or in the event of a sale of all or substantially
all of the Company’s assets or otherwise (each, an “Acquisition”), the Committee or the board of directors of any entity assuming the obligations of the Company hereunder (the “Successor Board”), shall, as to outstanding
Options, either (i) make appropriate provision for the continuation of such Options by substituting on an equitable basis for the shares then subject to such Options either (a) the consideration payable with respect to the outstanding
shares of Common Stock in connection with the Acquisition, (b) shares of stock of the surviving or successor corporation or (c) such other securities as the Successor Board deems appropriate, the fair market value of which shall not
materially exceed the fair market value of the shares of Common Stock subject to such Options immediately preceding the Acquisition; or (ii) upon written notice to the optionees, provide that all Options must be exercised, to the extent then
exercisable or to be exercisable as a result of the Acquisition, within a specified number of days of the date of such notice, at the end of which period the 

 Options shall terminate; or (iii) terminate all Options in exchange for a cash payment equal to the excess of the
fair market value of the shares subject to such Options (to the extent then exercisable or to be exercisable as a result of the Acquisition) over the exercise price thereof. 
 13.3. Recapitalization or Reorganization. In the event of a recapitalization or reorganization of the Company (other than a transaction described
in subparagraph 13.2 above) pursuant to which securities of the Company or of another corporation are issued with respect to the outstanding shares of Common Stock, an optionee upon exercising an Option shall be entitled to receive for the purchase
price paid upon such exercise the securities he or she would have received if he or she had exercised such Option prior to such recapitalization or reorganization. 
 13.4. Modification of ISOs. Notwithstanding the foregoing, any adjustments made pursuant to subparagraphs 13.1, 13.2 or 13.3 with respect to ISOs shall be made only after the Committee, after consulting with
counsel for the Company, determines whether such adjustments would constitute a “modification” of such ISOs (as that term is defined in Section 424 of the Code) or would cause any adverse tax consequences for the holders of such ISOs.
If the Committee determines that such adjustments made with respect to ISOs would constitute a modification of such ISOs or would cause adverse tax consequences to the holders, it may refrain from making such adjustments. 
 13.5. Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, then the Committee shall, as to
outstanding Options, at its discretion provide, upon written notice to the optionees, (i) that all Options must be exercised, to the extent then exercisable, within a specified number of days of the date of such notice, at the end of which
period, the Options shall terminate or (ii) that such Options (including those which have not yet vested) shall be exercisable within a specified number of days of such notice, at the end of which period the Options shall terminate. 

13.6. Issuances of Securities. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares subject to Options. No adjustments shall be made for dividends paid in cash or in property
other than securities of the Company. 
 13.7. Fractional Shares. No fractional shares shall be issued under the Plan and the optionee
shall receive from the Company cash in lieu of such fractional shares. 
 13.8. Adjustments. Upon the happening of any of the events
described in subparagraphs 13.1, 13.2 or 13.3 above, the class and aggregate number of shares set forth in paragraph 4 hereof that are subject to Stock Rights which previously have been or subsequently may be granted under the Plan shall also be
appropriately adjusted to reflect the events described in such subparagraphs. The Committee or the Successor Board shall determine the specific adjustments to be made under this paragraph 13 and, subject to paragraph 2, its determination shall be
conclusive. 
  

	14.	Means Of Exercising Options. 

 An Option (or any
part or installment thereof) shall be exercised by giving written notice to the Company at its principal office address, or to such transfer agent as the Company shall designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, accompanied by full payment of the purchase price therefor either (a) in United States dollars in cash or by check, (b) at the discretion of the Committee, through delivery of
shares of Common Stock having a fair market value equal as of the date of the exercise to the cash exercise price of the Option provided that such shares have been held by the optionee for at least six (6) months, (c) at the discretion of
the Committee, by delivery of the grantee’s personal recourse note bearing interest payable not less than annually at no less than 100% of the lowest applicable Federal rate, as defined in Section 1274(d) of the Code, (d) at the
discretion of the Committee and consistent with applicable law, through 

 the delivery of an assignment to the Company of a sufficient amount of the proceeds from the sale of the Common Stock
acquired upon exercise of the Option and an authorization to the broker or selling agent to pay that amount to the Company, which sale shall be at the participant’s direction at the time of exercise, or (e) at the discretion of the
Committee, by any combination of (a), (b), (c) and (d) above. If the Committee exercises its discretion to permit payment of the exercise price of an ISO by means of the methods set forth in clauses (b), (c), (d) or (e) of the
preceding sentence, such discretion shall be exercised in writing at the time of the grant of the ISO in question. The holder of an Option shall not have the rights of a shareholder with respect to the shares covered by such Option until the date of
issuance of a stock certificate to such holder for such shares. Except as expressly provided above in paragraph 13 with respect to changes in capitalization and stock dividends, no adjustment shall be made for dividends or similar rights for which
the record date is before the date such stock certificate is issued. 
 15. Term And Amendment Of Plan. 
 This Plan was adopted by the Board on December 12, 2001, subject, with respect to the validation of ISOs granted under the Plan, to approval of the
Plan by the stockholders of the Company at the next Meeting of Stockholders (the “Stockholder Approval”). If Stockholder Approval is not obtained prior to December 12, 2002, ISOs granted under the Plan prior to such date shall be
treated as Non-Qualified Options. The Plan shall expire at the end of the day on December 12, 2011 (except as to Options outstanding on that date). Subject to the provisions of paragraph 5 above, Options may be granted under the Plan prior to
the date of Stockholder Approval. The Board may terminate or amend the Plan in any respect at any time, except that, if Stockholder Approval has been obtained, then the Board must obtain the approval of the stockholders within twelve
(12) months before or after the Board adopts a resolution authorizing any of the following actions: (a) to increase the total number of shares that may be issued under the Plan (except by adjustment pursuant to paragraph 13); (b) to
modify the provisions of paragraph 3 regarding eligibility for grants of ISOs; (c) to modify the provisions of paragraph 6(B) regarding the exercise price at which shares may be offered pursuant to ISOs (except by adjustment pursuant to
paragraph 13); and (d) to extend the expiration date of the Plan. Except as otherwise provided in this paragraph 15, in no event may action of the Board or stockholders alter or impair the rights of a grantee, without such grantee’s
consent, under any Stock Right previously granted to such grantee. 
 16. Modifications Of ISOs; Conversion Of ISOs Into Non-Qualified Options.

 Subject to paragraph 13(D), without the prior written consent of the holder of an ISO, the Committee shall not alter the terms of such ISO
(including the means of exercising such ISO) if such alteration would constitute a modification (within the meaning of Section 424(h)(3) of the Code). The Committee, at the written request or with the written consent of any optionee, may in its
discretion take such actions as may be necessary to convert such optionee’s ISOs (or any installments or portions of installments thereof) that have not been exercised on the date of conversion into Non-Qualified Options at any time prior to
the expiration of such ISOs, regardless of whether the optionee is an employee of the Company or a Related Corporation at the time of such conversion. Such actions may include, but shall not be limited to, extending the exercise period or reducing
the exercise price of the appropriate installments of such ISOs. At the time of such conversion, the Committee (with the consent of the optionee) may impose such conditions on the exercise of the resulting Non-Qualified Options as the Committee in
its discretion may determine, provided that such conditions shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to give any optionee the right to have such optionee’s ISOs converted into Non-Qualified Options, and no
such conversion shall occur until and unless the Committee takes appropriate action. Upon the taking of such action, the Company shall issue separate certificates to the optionee with respect to Options that are Non-Qualified Options and Options
that are ISOs. 

 17. Repricing. 
 Without the prior approval of the Company’s stockholders obtained in the manner stated in Section 15, Options issued under the Plan will not be repriced, replaced or regranted through cancellation or by
lowering the Option exercise price of a previously granted Option. 
 18. Application of Funds. 
 The proceeds received by the Company from the sale of shares pursuant to Options granted and Purchases authorized under the Plan shall be used for general
corporate purposes. 
 19. Notice To Company of Disqualifying Disposition. 
 By accepting an ISO granted under the Plan, each optionee agrees to notify the Company in writing immediately after such optionee makes a Disqualifying
Disposition (as described in Sections 421, 422 and 424 of the Code and regulations thereunder) of any stock acquired pursuant to the exercise of ISOs granted under the Plan. A Disqualifying Disposition is generally any disposition occurring on or
before the later of (a) the date two (2) years following the date the ISO was granted or (b) the date one (1) year following the date the ISO was exercised. 
 20. Withholding of Additional Taxes. 
 Upon the exercise of a Non-Qualified Option, the transfer of a
Non-Qualified Stock Option pursuant to an arm’s length transaction, the grant of an Award, the making of a Purchase of Common Stock for less than its fair market value, the making of a Disqualifying Disposition (as defined in paragraph 19), the
vesting or transfer of restricted stock or securities acquired on the exercise of an Option hereunder, or the making of a distribution or other payment with respect to such stock or securities, the Company may withhold taxes in respect of amounts
that constitute compensation includible in gross income. The Committee in its discretion may condition (i) the exercise of an Option, (ii) the transfer of a Non-Qualified Stock Option, (iii) the grant of an Award, (iv) the making
of a Purchase of Common Stock for less than its fair market value, or (v) the vesting or transferability of restricted stock or securities acquired by exercising an Option, on the grantee’s making satisfactory arrangement for such
withholding. Such arrangement may include payment by the grantee in cash or by check of the amount of the withholding taxes or, at the discretion of the Committee, by the grantee’s delivery of previously held shares of Common Stock or the
withholding from the shares of Common Stock otherwise deliverable upon exercise of a Option shares having an aggregate fair market value equal to the amount of such withholding taxes. 
 21. Restrictions on Transfer of Shares. 
 Except as otherwise determined by the Committee, any shares
issued upon exercise of Options or in respect of other Stock Rights hereunder shall be subject to the following transfer restrictions. 
 21.1. Right of First Refusal. The transfer of any shares of common stock of the Company acquired upon exercise of an Option or as a result of Awards or Purchases under this Plan is subject to the Company’s right of first refusal
set forth in Article VIII of the Company’s bylaws. A copy of Article VIII is attached hereto as Exhibit A and incorporated herein. 
 21.2. Call Rights. 
 (a) In the event that a Plan participant’s employment by the Company or any Affiliate (as such term
is defined in Rule 405 promulgated under the Securities Act of 1933, as amended (the “Act”)) shall be terminated by the Company or an Affiliate “for cause” (as defined below), any Common Stock held by such participant as a result
of the grant or exercise of any Stock Right under the Plan shall be subject to a call by the Company such that the Company shall be entitled to purchase any or 

 all of such Common Stock at the lesser of (i) book value (as determined by the Company’s accountants)
(“Book Value”), or (ii) the exercise/purchase price per share for which such Common Stock was acquired by the original holder thereof from the Company (“Exercise Price”). For purposes hereof, “for cause” shall mean
(i) in the case of any Plan participant whose employment with the Company is governed by an employment agreement, the meaning given to such term in such employment agreement, and (ii) for all other participants, as determined in good faith
by the Committee: (1) failure to perform material duties and responsibilities; (2) willful dishonesty, fraud or material misconduct with respect to the business or affairs of the Company; (3) the commission of a felony crime;
(4) chronic absenteeism; (5) chronic alcohol abuse or illegal drug abuse; or (6) violation of any non-competition, proprietary rights, confidentiality, or other similar agreements or covenants in favor of the Company. 
 (b) In the event that (i) a Plan participant dies, (ii) is permanently and totally disabled and his/her employment is terminated,
(iii) the participant’s employment by the Company or any of its Affiliates shall be terminated by the Company or an Affiliate without Cause or (iv) the participant resigns his/her employment, any Common Stock held by such participant
as a result of any grant or exercise of Stock Right under the Plan shall be subject to a call by the Company such that the Company shall be entitled to purchase any or all such Common Stock at the “Fair Market Value” of such shares. For
purposes hereof, “Fair Market Value” shall have the meaning set forth in Section 6(D) above. 
 (c) The Company’s rights
under subsections (a) and (b) above shall be exercisable for a period of six (6) months from the date of termination of the participant’s employment or other service. In the event the Company purchases any Common Stock pursuant
to this Section 21.2, payment may be made by the Company, at its option by either (i) a lump sum cash payment or (ii) pursuant to a promissory note made by the Company to the shareholder as payee which note shall bear interest at the
Internal Revenue Service published applicable federal rate per annum and be payable over a period not to exceed sixty (60) months in equal monthly installments of principal and interest. 
 21.3 Lock-Up. No Plan participant shall, without the prior written consent of the Company, sell, assign, transfer, grant a proxy to any person to
vote or otherwise act in respect of, grant a participation in, grant a security interest in, pledge, encumber or otherwise dispose of, whether by operation of law or otherwise (any of the foregoing being referred to hereinafter as a
“Disposition”), any shares of Common Stock or any other equity interest in the Company, now owned or hereafter acquired by such shareholder as a result of the grant or exercise of any Stock Right, to any competitor or Affiliate of any
competitor of the Company. 
 21.4 Transfers in Violation; Legend. The Company shall not be required to transfer any shares of Common
Stock on its books which shall have been sold, assigned or otherwise transferred in violation of the Plan, or to accord the right to vote as such owner or to pay dividends to, any person or organization to which any such shares shall have been sold,
assigned or otherwise transferred in violation hereof. All certificates representing the shares to be issued to participants in the Plan as a result of the grant or exercise of any Stock Right shall have endorsed thereon a legend substantially as
follows: “THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS SET FORTH IN ARTICLE VIII OF THE COMPANY’S BYLAWS AND IN A STOCK AWARD AGREEMENT DATED
                    , COPIES OF WHICH ARE ON FILE WITH THE SECRETARY OF THE COMPANY. NO TRANSFER, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION
OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF THE STOCK AWARD AGREEMENT. THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF
THE STOCK AWARD AGREEMENT. 
 21.5 Termination upon IPO. The provisions of Section 21.1-21.4 shall terminate upon the
consummation of a public offering of any of the Company’s securities pursuant to a registration statement filed with the Securities and Exchange Commission pursuant to the Act. 

 22. Purchase for Investment.  
 Unless the offering and sale of shares to be issued upon exercise of an Option or as a result of a Purchase shall have been effectively registered under the Act, the Company shall be under no obligation to issue such
shares unless and until the following conditions have been fulfilled: Such person(s), prior to the receipt of the shares, shall warrant to the Company that such person(s) are acquiring the shares for their own account, for investment, and not with a
view to, or in connection with, the distribution of any such shares. Such person(s) shall also be bound by the following legend which shall be endorsed upon the share certificate(s): THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR CERTAIN STATE SECURITIES LAWS AND MAY NOT BE SOLD, OFFERED FOR SALE, ASSIGNED, TRANSFERRED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SHARES
UNDER THE SECURITIES ACT OF 1933, AS AMENDED AND SUCH STATE LAWS AS MAY BE APPLICABLE, OR DELIVERY OF AN OPINION OF COUNSEL TO THE COMPANY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED. 
 23. Governmental Regulation. 
 The Company’s
obligation to sell and deliver shares of the Common Stock under this Plan is subject to the approval of any governmental authority required in connection with the authorization, issuance or sale of such shares. Government regulations may impose
reporting or other obligations on the Company with respect to the Plan. For example, the Company may be required to send tax information statements to employees and former employees that exercise ISOs under the Plan, and the Company may be required
to file tax information returns reporting the income received by grantees of Options in connection with the Plan. 
  

	24.	Governing Law. 

 The validity and construction of
the Plan and the instruments evidencing Stock Rights shall be governed by the laws of the State of Delaware, or the laws of any jurisdiction in which the Company or its successors in interest may be organized.
