Committee shall, in addition to rights they may have as directors of the Company, be fully protected by the Company with respect to any such action, determination or interpretation. 

(f) It is the further intent of the Plan that it conform in all respects with (i) the requirements of Rule 16b-3 of Securities
Exchange Act of 1934 (“Rule 16b-3”) and (ii) the Code. To the extent that any aspect of the Plan or its administration is at any time viewed as inconsistent with the requirements of Rule 16b-3 or the Code, that aspect shall be
deemed to be modified, deleted, or otherwise changed as necessary to ensure continued compliance with Rule 16b-3 or Code requirements. 
 4. Number of Shares. The Board is authorized to appropriate, issue and sell for the purposes of the Plan, and the Governing Committee is authorized to grant Options or Restricted Stock with respect

qualify as ISOs will be granted only to Key Employees. Key Employees and other Employees may hold more than one Option Agreement under the Plan and may hold Stock Awards under the Plan and options or awards granted pursuant to other plans or
otherwise. 
 6. Options. The Governing Committee may grant Options pursuant to this Plan. 

(a) Option Price. The Governing Committee shall determine the purchase price for the Option Shares, provided that the purchase
price to be paid by Optionees for the 

  
 -4-

 
Option Shares shall not be less than 100 percent of the Fair Market Value of the Option Shares at the time the Option is granted. The purchase price for the Option Shares shall be a fixed,
non-fluctuating, price. 
 (b) Duration and Exercise of Options. 

(i) Each Option granted under the Plan shall be exercisable on such date or dates and during such period and for such number of shares
as shall be determined pursuant to the provisions of the Option Agreement. The Governing Committee shall have the right to accelerate the date of exercise of any Option, provided that the Governing Committee shall not accelerate the exercise of any
ISO granted if such acceleration would violate the annual vesting limitation contained in Section 422(d)(1) of the Code. In no event shall the Governing Committee have the discretion to extend an Option beyond the earlier of the last date that
the Option could have been exercised under the initial term of the Option and the date that is 10 years after the initial Date of Grant, unless said extension is granted at a time when the exercise price of the Option does not equal or exceed the
Fair Market Value of the stock that could be purchased pursuant to the Option. 
 (ii) Except as otherwise permitted under
Subsection (d) of this Section 6, during the lifetime of the Optionee, the Option shall be exercisable only by the Optionee; provided, that in the event of the legal disability of an Optionee, the guardian or personal representative
of the Optionee may exercise the Option. However, if the Option is an ISO it may be exercised by the guardian or personal representative of the Optionee only if such guardian or personal representative obtains a ruling from the Internal Revenue
Service or an opinion of counsel to the effect that neither the grant nor the exercise of such power is violative of Section 422(b)(5) of the Code. Any opinion of counsel must be both from counsel and in a form acceptable to the Governing
Committee. 
 (iii) The Governing Committee may determine whether any Option shall be exercisable as provided in item
(i) of this Subsection (b) or whether the Options shall be exercisable in installments only; if the Governing Committee determines the latter, it shall determine the number of installments and the percentage of the Option exercisable at
each installment date. All such installments shall be cumulative. 
 (iv) If the Optionee ceases to be employed by either the
Company or a Related Company because of the death or permanent and total disability (as defined in Section 22(e)(3) of the Code) of the Optionee, any Option held by the Optionee at the time his employment ceases may be exercised within 90 days
after the date his employment ceased, but only to the extent that the Option was exercisable according to its terms on the date the Optionee’s employment ceased. After such 90-day period, any unexercised portion of an Option shall expire.

 (v) Notwithstanding the provisions of item (iv) of this Subsection (d), if an Optionee’s employment by the Company
or a Related Company ceases for any reason other than the Optionee’s death or permanent and total disability, any unexercised portion of any Option held by the Optionee at the time his employment ceases may be exercised within 30 days after the
date his employment ceased, but only to the extent that the Option was exercisable 

  
 -5-

 
according to its terms on the date the Optionee’s employment ceased. After such date, any unexercised portion of an Option shall expire. 

(vi) Each Option may be exercised in whole or part by delivering to the Chief Financial Officer of the Company written notice of the
number of shares with respect to which the Option is to be exercised and by paying in full the purchase price for the Option Shares purchased as set forth in Subsection (c) of this Section 6; provided, that an Option may not be
exercised in part unless the purchase price for the Option Shares purchased is at least $2,000. 
 (vii) To the extent required
to qualify for the exemption provided by Rule 16b-3 under the Exchange Act, and any successor provision, at least six months must elapse from the date of acquisition of an Option by any person who is subject to the reporting requirements of
Section 16(a) of the Exchange Act to the date of exercise of such Option or disposition of the Option Shares. 
 (c)
Payment for Option Shares. If the purchase price of the Option Shares purchased by any Optionee at one time exceeds $2,000, the Governing Committee may permit all or part of the purchase price for the Option Shares to be paid by the Optionee
by (a) delivering to the Company shares of the Company’s Common Stock previously owned by the Optionee with a Fair Market Value as of the date of payment equal to the portion of the purchase price for the Option Shares that the Optionee
does not pay in cash, (b) having shares withheld from the amount of shares to be received by the Optionee, or (c) complying with any other payment mechanisms as the Governing Committee may approve from time to time. As a condition to the
exercise of any Option granted under this Plan, the Optionee shall make such arrangements as the Governing Committee may require for the satisfaction of any federal, state or withholding tax obligations which may arise in connection with such
exercise. The issuance, transfer or delivery of certificates of shares of Common Stock pursuant to the exercise or Options may be delayed, at the discretion of the Governing Committee, until the Governing Committee is satisfied that the applicable
requirements of federal and state securities laws and the withholding provisions of the Code have been met. Until such person has been issued a certificate or certificates for the Option Shares so purchased, he or she shall possess no rights of a
recordholder with respect to any of such shares. 
 (d) Nontransferability of Option. No Option granted under the Plan
shall be transferable by the Optionee, either voluntarily or involuntarily, except by will or the laws of descent and distribution, pursuant to a qualified domestic relations order as defined in the Code, or pursuant to the Employee Retirement
Income Security Act or rules promulgated thereunder; except that (a) Optionees who are not subject to Section 16(b) of the Exchange Act may upon written notice transfer a Non-ISO (i) to an Optionee’s spouse, parents, siblings, or
lineal descendants, or (ii) to a trust for the benefit of the Optionee or any of the Optionee’s spouse, parents, siblings, or lineal descendants, or (iii) to any corporation or partnership controlled by the Optionee; and
(b) Optionees who are subject to Section 16(b) of the Exchange Act may transfer Non-ISOs to immediate family members and family trusts. No Option shall be subject to execution, attachment or similar process. Except as specifically provided
herein, any attempt to transfer the Option shall void the Option. 

  
 -6-

 (e) Limitation on Amount of Option. The aggregate Fair Market Value (determined at
the time any ISO is granted) of the Common Stock with respect to which an Optionee’s ISOs, together with incentive stock options granted under any other plan of the Company and any parent, are exercisable for the first time by such Optionee
during any calendar year shall not exceed $100,000. If an Optionee holds ISOs that become first exercisable (including as a result of acceleration of exercisability under the Plan) in any one year for shares having a Fair Market Value at the date of
grant in excess of $100,000, then the most recently granted of the ISOs, to the extent that they are exercisable for shares having an aggregate Fair Market Value in excess of the limit, shall be deemed to be Non-ISOs. 

(f) Ten Percent Shareholder Rule. With respect to ISOs, no Option may be granted to a Key Employee who, at the time the Option is
granted, owns stock possessing more than 10 percent of the total combined voting power of all classes of stock of the Company or of any “parent corporation” or “subsidiary corporation” as those terms are defined in
Section 424 of the Code, unless at the time the Option is granted the purchase price for the Option shares is at least 110 percent of the Fair Market Value of the Option Shares at the time the ISO is granted and such Option by its terms is not
exercisable after the expiration of five years from the Date of Grant. For purposes of the preceding sentence, stock ownership shall be determined as provided in Section 424 of the Code. 

7. Restricted Stock: The Governing Committee may grant shares of Restricted Stock pursuant to this Plan. To the extent consistent
with the Company’s Bylaws, at the Governing Committee’s election, shares of Restricted Stock may be (i) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock lapse,
or (ii) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Governing Committee and shall contain an appropriate legend clearly stating that the transferability of the Restricted Stock
represented by the certificate is restricted by the Restricted Stock Agreement and this Plan. The Restricted Stock Agreements shall be in such form and shall contain such terms and conditions as the Governing Committee shall deem appropriate from
time to time and the terms and conditions of separate Restricted Stock Agreements need not be identical; provided, however, that each Restricted Stock Agreement shall include (through incorporation of the provisions hereof by reference
in the agreement or otherwise) the substance of each of the following provisions: 
 (a) Consideration. Restricted Stock
may be awarded in consideration for (A) past or future services actually or to be rendered to the Company or a Related Company, or (B) any other form of legal consideration that may be acceptable to the Governing Committee in its sole
discretion and permissible under applicable law. 
 (b) Vesting. Shares of Restricted Stock may be subject to forfeiture
to the Company in accordance with a vesting schedule to be determined by the Governing Committee in its sole discretion and set forth in the Restricted Stock Agreement. 
 (c) Termination of Service. In the event a Restricted Stock holder ceases to be employed by either the Company or a Related Company, the Company may receive pursuant to a forfeiture provision to be
determined by the Governing Committee in its sole discretion and set 

  
 -7-

 
forth in the Restricted Stock Agreement, any or all Restricted Shares that have not vested as of the date of termination. 
 (d) Transferability. Rights to acquire shares of Common Stock under a Restricted Stock Agreement shall be transferable by the holder only upon such terms and conditions as are set forth in the
Restricted Stock Agreement, as the Governing Committee shall determine in its sole discretion, so long as such Common Stock remains subject to the terms and conditions of the Restricted Stock Agreement. 

8. Changes in Stock, Adjustments, Etc. 
 (a) In the event that each of the outstanding shares of Common Stock (other than shares held by dissenting shareholders which are not changed or exchanged) should be changed into, or exchanged for, a
different number or kind of shares of stock or other securities of the Company, or, if further changes or exchanges of any stock or other securities into which the Common Stock shall have been changed, or for which it shall have been exchanged,
shall be made (whether by reason of merger, consolidation reorganization, recapitalization, stock dividends, reclassification, split-up, combination or shares or otherwise), then there shall be substituted for each share of Common Stock that is
subject to the Plan but not subject to an outstanding Option or Restricted Stock thereunder, the number and kind of shares of stock or other securities into which each outstanding share of Common Stock (other than shares held by dissenting
shareholders which are not changed or exchanged) shall be so changed or for which each outstanding share of Common Stock (other than shares held by dissenting shareholders) shall be exchanged, provided, in the event that the Optionee is providing
direct services to the Company at the time the shares are substituted, such shares shall constitute “service recipient stock” as that term is defined by the IRS for purposes of Section 409A of the Code. Any securities so substituted
shall be subject to similar successive adjustments. 
 (b) In the event of any such changes or exchanges, the Governing
Committee shall determine whether, in order to prevent dilution or enlargement of rights, an adjustment should be made in the number, or kind, or Option price of the shares or other securities then subject to an Option or Restricted Stock granted
pursuant to the Plan and the Governing Committee shall make any such adjustment, and such adjustments shall be made and shall be effective and binding for all purposes of the Plan. 

9. Relationship to Employment. Nothing contained in the Plan, or in any Stock Award granted pursuant to the Plan, shall confer
upon any recipient or holder of a Stock Award any right with respect to continuance of employment by the Company or any Related Company, or interfere in any way with the right of the Company or any Related Company to terminate the employment of a
Stock Award recipient or holder at any time. 
 10. Rights as a Shareholder. No person shall have any rights as a
shareholder with respect to any shares covered by an Stock Award until that person shall become the holder of record of such shares (whether or not subject to forfeiture) and, except as provided in Section 8, no adjustments shall be made
for dividends or other distributions or other rights as to which there is an earlier record date. 

  
 -8-

 11. Securities Laws Requirements. No Award Shares shall be issued unless and until,
in the opinion of the Company, any applicable registration requirements of the Securities Act of 1933, as amended (“Securities Act”), any applicable listing requirements of any securities exchange on which stock of the same class is
then listed, and any other requirements of law or of any regulatory bodies having jurisdiction over such issuance and delivery, have been fully complied with. Each Option, each Restricted Stock certificate and each Award Share certificate may be
imprinted with legends reflecting federal and state securities laws, restrictions and conditions, and the Company may comply therewith and issue “stop transfer” instructions to its transfer agent and registrar in good faith without
liability. 
 12. Disposition of Shares. Each Optionee, as a condition of exercise, and each Restricted Stock holder, as
a condition to the Restricted Stock grant, shall represent, warrant and agree, in a form of written certificate approved by the Company, as follows: (a) that all Award Shares are being acquired solely for his own account and not on behalf of
any other person or entity; (b) that no Award Shares will be sold or otherwise distributed in violation of the Securities Act, or any other applicable federal or state securities laws; (c) that if he is subject to reporting requirements
under Section 16(a) of the Exchange Act, he will (i) not violate Section 16(b) of the Exchange Act, (ii) furnish the Company with a copy of each Form 4 and Form 5 filed by him, and (iii) timely file all reports required
under the federal securities laws; and (d) that he will report all sales of Award Shares to the Company in writing on a form prescribed by the Company. 
 13. Effective Date of Plan; Termination Date of Plan. The Plan shall be effective on the date the Plan has been approved by the Board and the shareholders of the Company. The Plan was adopted,
subject to shareholder approval, by the Board as of September 12, 2011. The Plan shall terminate on September 12, 2021, except as to Stock Awards previously granted and outstanding under the Plan at that time. No Stock Awards shall be
granted after the date on which the Plan terminates. In no event may the Option period exceed ten years from the date on which the Option is granted. The Plan may be abandoned or terminated at any earlier time by the Board, except with respect to
any Stock Awards then outstanding under the Plan. 
 14. Withholding Taxes. The Company, or any Related Company, may take
such steps as it may deem necessary or appropriate for the withholding of any taxes which the Company, or any Related Company, is required by any law or regulation or any governmental authority, whether federal, state or local, domestic or foreign,
to withhold in connection with any Stock Award including, but not limited to, the withholding of all or any portion of any payment or the withholding of issuance of Option Shares to be issued upon the exercise of any Option. 

15. Change in Control, Stock Dividends, Reorganization and Other Extraordinary Actions. 

(a) If (i) the Company shall at any time be involved in a transaction described in Section 424(a) of the Code (or any successor
provision) or any “corporate transaction” described in the regulations thereunder; (ii) the Company shall declare dividends payable in, or shall subdivide or combine, its Common Stock or (iii) any other event with substantially
the same effect shall occur, the Governing Committee shall, with respect to each outstanding Option, proportionately adjust the number of Option Shares and/or the exercise price per share so as to

  
 -9-

 
preserve the rights of the Optionee substantially proportionate to the rights of the Optionee prior to such event, and to the extent that such action shall include an increase or decrease in the
number of Option Shares subject to outstanding Options, the number of shares available under this Plan shall automatically be increased or decreased, as this case may be, proportionately, without further action on the part of the Governing
Committee, the Company or the Company’s shareholders. 
 (b) If the Company is liquidated or dissolved, the Governing
Committee may allow the holders of any outstanding Options to exercise all or any part of the unvested portion of the Options held by them; provided, however, that such Options must be exercised prior to the effective date of such liquidation or
dissolution. If the Option Holders do not exercise their Options prior to such effective date, each outstanding Option shall terminate as of the effective date of the liquidation or dissolution. 

(c) The grant of a Stock Award 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, consolidate or dissolve, to liquidate or to sell or transfer all or part of its business or assets. 
 (d) In the event of a Change in Control (as defined below) of the Company, the Governing Committee may, in its discretion, accelerate all outstanding Options and Restricted Stock so that (i) Options
immediately become exercisable for the duration of the term of the Option and (ii) Restricted Stock immediately becomes fully vested. For purposes of this Subsection (d), “Change in Control” shall mean the occurrence of any of
the following events: (i) any “person” or “group” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the “beneficial owner” (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the Company’s then outstanding voting securities; (ii) a
change in the composition of the Board of the Company occurring within a one-year period, resulting in the change of sixty percent or more of the directors serving on the Board from the beginning of the of the one-year period to the end of the
one-year period; (iii) there is a merger or consolidation of the Company in which the Company does not survive as an independent public company; or (iv) the acquisition of all or substantially all the Company’s assets in a transaction
or series of related transactions with a third-party purchaser. 
 (e) If at any time the Company declares an Extraordinary
Dividend, as defined below, all (i) Options shall accelerate and thereupon become immediately exercisable for the duration of the term of the Option and (ii) Restricted Stock shall become immediately fully vested. For purposes of this
Subsection (e), “Extraordinary Dividend” shall mean a cash dividend payable to holders of record of the Common Stock in an amount in excess of 10% of the then Fair Market Value of the Company’s Common Stock. 

16. Restrictions. The Company may impose such restrictions on Options and Restricted Stock granted hereunder, or the Award Shares
underlying such grants, as it may deem advisable, including without limitation restrictions under the federal securities laws, the requirements of any stock exchange or similar organization and any blue sky, state or foreign securities laws
applicable to such securities.

administering the Plan shall be borne by the Company. 
 (c) This Plan shall be construed to be in addition to any and all other
compensation plans or programs. Neither the adoption of the Plan by the Board nor the submission of the Plan to the shareholders of the Company shall be construed as creating any limitations on the power of authority of the Board to adopt such other
additional incentive or other compensation arrangements as the Board may deem necessary or desirable. 
 (d) The corporate laws
of the State of Colorado shall govern all issues concerning the relative rights of the Company and its shareholders under the Plan. All other questions and obligations under the Plan shall be construed and enforced in accordance with the internal
laws of the State of California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of California or any other jurisdiction) that would cause the application of the laws of any jurisdiction other
than the State of California. 
 (e) Notwithstanding anything to the contrary contained in this Plan, this Plan is intended to
comply with the California Corporate Securities Law of 1968 and the rules and regulations promulgated thereunder. 
 (f) If any
provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been
included. 
 (g) Headings are given to the sections of this Plan solely as a convenience to facilitate reference. The reference
to any statute, regulation or other provision of law shall be construed to refer to any amendment to or successor of such provision of law.

 2. Purpose and Scope. 

(a) The purpose of this Plan is to advance the interests of the Company and its shareholders by affording Nonemployee Directors, whose
participation and guidance contribute to the successful operation of the Company, an opportunity for investment in the Company and the incentive advantages inherent in stock ownership in this Company. The Plan is also intended to further the efforts
of the company to attract and retain qualified Non-Employee Directors. 
 (b) This Plan authorizes that Options be granted to
Nonemployee Directors according to the formula set forth in Section 3 of this Plan. 
 (c) It is the further intent
of the Plan that it conform in all respects with (i) the requirements of Rule 16b-3 of the Securities Exchange Act of 1934 (“Rule 16b-3”) and (ii) the Code. To the extent that any aspect of the Plan or its administration
is at any time viewed as inconsistent with the requirements of Rule 16b-3 or the Code, that aspect shall be deemed to be modified, deleted, or otherwise changed as necessary to ensure continued compliance with Rule 16b-3 or Code requirements.

 (d) Notwithstanding any other provision in the Plan or an Option Agreement to the contrary, if and to the extent that Code
Section 409A is deemed to apply to the Plan or any 

  
 -2-

 
Option granted under the Plan, it is the general intention of the Company that the Plan and all such Options shall, to the extent practicable, comply with Code Section 409A, and the Plan and
any such Option shall, to the extent practicable, be construed in accordance therewith. Without in any way limiting the effect of the foregoing, in the event that Code Section 409A requires that any special terms, provisions or conditions be
included in the Plan or any Option, then such terms, provisions and conditions shall, to the extent practicable, be deemed to be made a part of the Plan or Option, as applicable. Further, in the event that the Plan or any Option shall be deemed not
to comply with Code Section 409A, then neither the Corporation nor the Board shall be liable to any Optionee or other person for actions, decisions or determinations made in good faith. 

3. Operation of the Plan. 
 (a) Grant of Options; Amount and Timing. The Board may grant Options to Nonemployee Directors in such amounts and subject to such terms and conditions as set forth in any Director Compensation
Program of the Company adopted by the Board, subject to the provisions of the Plan. All Options shall be exercisable only as set forth in Sections 3(c) and 6 below and shall be subject to the other terms and conditions set forth in this Plan
or otherwise established by the Company. 
 (b) Option Purchase Price. The exercise price for each Option Share shall be
the Fair Market Value of the Company’s Common Stock on the Date of Grant. 
 (c) Term. Each Option shall expire ten
years after the Date of Grant, except that an Option will expire, if not exercised, 90 days after the Optionee ceases to be a Non-Employee Director of the Company. 
 (d) Amendments. This Plan may be changed or modified from time to time provided, however, that, (i) no such change or modification shall impair any Option previously granted under the Plan;
(ii) the provisions relating to the amount, price and timing of the Options shall not be amended more than once every six months other than to comport with changes in the Code, the Employee Retirement Income Security Act, or rules promulgated
thereunder, or other applicable law; and (iii) the approval by the affirmative vote of the holders of a majority of shares of the Company’s securities present, or represented, and entitled to vote at a meeting duly held in accordance with
the applicable laws of the State of Colorado, shall be required for any amendment which would do any of the following: 
  

	 	(i)	materially modify the eligibility requirements for receiving Options under the Plan; 

 

	 	(ii)	except as provided in Section 8 relative to capital changes, increase the number of shares purchasable pursuant to the granting of any Option hereunder or
the exercise price of each Option; 

  

	 	(iii)	increase the maximum term of Options granted; 

  

	 	(iv)	decrease the minimum price at which Options may be granted; 

  
 -3-

	 	(v)	change the dollar amount pursuant to which Options may be granted at any one time; 

 

	 	(vi)	change the timing of Option Grants; or 

  

	 	(vii)	increase the term of the Plan. 

4. Number of Shares. The Board is authorized to appropriate, issue and sell for the purposes of the Plan, an aggregate maximum of
(i) the sum of (A) 100,000 shares of Common Stock, plus (B) any shares of Common Stock remaining available for issuance under the Prior Plan as of the Effective Date of the Plan, plus (C) any shares of Common Stock subject to an
Option granted under the Prior Plan or the Plan, which Option at any time is forfeited, cancelled, terminated, expires or lapses for any reason without the issuance of shares pursuant to the Option or (ii) the number and kind of shares of stock
or other securities which in accordance with Section 8 may be substituted for the shares authorized under sub-section (i) or into which such shares shall be adjusted. 

5. Eligibility. Options shall be granted under the Plan only to Nonemployee Directors provided that any Nonemployee Director may
waive his right to participate in the Plan. 
 6. Exercise of Options. 

(a) Each Option granted pursuant to this Plan shall be exercisable in full commencing six months after the Date of Grant, except as
otherwise determined by the Board. 
 (b) Each Option may be exercised in whole or in part by delivering to the Chief Financial
Officer of the Company written notice of the number of shares with respect to which the Option is to be exercised and by paying in full the purchase price for the Option Shares as set forth in Section 7 herein; provided, that an Option
may not be exercised in part unless the purchase price for the Option Shares purchased is at least $2,000. 
 (c) No Option may
be exercised, and no Option Shares may be sold, transferred or otherwise disposed of for a period of at least six months following the Date of Grant of the Option. 

  
 -4-

 7. Payment for Option Shares. Upon exercise of any Option, the aggregate exercise
price shall be paid to the Company in cash or by certified or cashier’s check. For any single purchase by an Optionee of Option Shares at a total purchase price in excess of $2,000, the Company, in its sole discretion, upon request by the
Optionee, may permit all or part of the purchase price for the Option Shares to be paid by (a) delivery to the Company for cancellation shares of the Common Stock previously owned by the Optionee (“Previously Owned Shares”)
with a Fair Market Value as of the date of the payment equal to the portion of the purchase price for the Option Shares that the Optionee does not pay in cash; (b) having shares withheld from the amount of shares to be received by the Optionee;
or (c) complying with any other payment mechanism as the Company may approve from time to time. Notwithstanding the above, an Optionee shall be permitted to exercise his Option by delivering Previously Owned Shares only if he has held, and
provides appropriate evidence of such, the Previously Owned Shares for more than six months prior to the date of exercise. This period (the “Holding Period”) may be extended by the Company acting in its sole discretion as is
necessary, in the opinion of the Company, so that, under generally accepted accounting principles, no compensation shall be considered to have been or to be paid to the Optionee as a result of the exercise of the Option in this manner. At the time
the Option is exercised, the Optionee shall provide an affidavit, and such other evidence and documents as the Company shall request, to establish the Optionee’s Holding Period. As indicated above, an Optionee may deliver shares of Common Stock
as part of the purchase price only if the Company, in its sole discretion agrees, on a case by case basis, to permit this form of payment. 
 8. Change in Stock, Adjustments, Etc. 
 (a) In the event that each of the
outstanding shares of Common Stock (other than shares held by dissenting shareholders which are not changed or exchanged) should be changed into, or exchanged for, a different number or kind of shares of stock or other securities of the Company, or
if further changes or exchanges of any stock or other securities into which the Common Stock shall have been changed, or for which it shall have been exchanged, shall be made (whether by reason of merger, consolidation, reorganization,
recapitalization, stock dividends, reclassification, split-up, combination of shares or otherwise) then there shall be substituted for each share of Common Stock that is subject to the Plan but not subject to an outstanding Option hereunder, the
number and kind of shares of stock or other securities into which each outstanding shares of Common Stock (other than shares held by dissenting shareholders which are not changed or exchanged) shall be so changed or for which each outstanding share
of Common Stock (other than shares held by dissenting shareholders) shall be so changed or for which each such share shall be exchanged. Any securities so substituted shall be subject to similar successive adjustments. 

(b) In the event of any such changes or exchanges, (i) the number, or kind, or exercise price of the Option Shares or other
securities that are then subject to an Option or Options granted pursuant to the Plan shall be deemed automatically adjusted in order to prevent dilution or enlargement of rights and (ii) such adjustments shall be effective and binding for all
purposes or the Plan. 
 9. Nontransferability of Option. Except as herein provided, no Option granted under the Plan
shall be transferable by the Optionee, either voluntarily or involuntarily, except by will, 

  
 -5-

 
by the laws of descent and distribution, or pursuant to a qualified domestic relations order as defined in the Code or the Employee Retirement Income Security Act or rules promulgated thereunder;
and no Option shall be subject to execution, attachment or similar process. Except as may be permitted by the preceding sentence, an Option shall be exercisable during the Optionee’s lifetime only by him or by his guardian or legal
representative. Any attempt to transfer an Option except as otherwise herein provided shall void the Option. Notwithstanding anything herein to the contrary, an Option may be transferred to an immediate family member or a family trust if such
transfer is then permitted by the rules adopted under Section 16(b) of the Securities Exchange Act of 1934, as amended. 

10. Rights as a Shareholder. No person shall have any rights as a shareholder with respect to any shares covered by an Option
until that person becomes the holder of record of such shares and, except as provided in Section 8, no adjustments shall be made for dividends or other distributions or other rights as to which there is an earlier record date.

 11. Securities Laws Requirements. No Option Shares shall be issued unless and until, in the opinion of the Company,
any applicable registration requirements of the Securities Act of 1933, as amended (“Securities Act”), any applicable listing requirements of any securities exchange on which stock of the same class is then listed, and any other
requirement of law or of any regulatory bodies having jurisdiction over such issuance and delivery, have been fully complied with. Each Option Agreement and each Option Share certificate may be imprinted with legends reflecting federal and state
securities laws restrictions and conditions, and the Company may comply therewith and issue “stop transfer” instructions to its transfer agent and registrar in good faith without liability. 

12. Disposition of Shares. To the extent reasonably requested by the Company, each Optionee, as a condition of exercise, shall
represent, warrant and agree, in a form of written certificate approved by the Company, as follows: (a) that all Option Shares are being acquired solely for his/her own account and not on behalf of any other person or entity; (b) that no
Option Shares will be sold or otherwise distributed in violation of the Securities Act or any other applicable federal or state securities laws; (c) that he/she will report all sales of Option Shares to the Company in writing on a form
prescribed by the Company; and (d) that if he/she is subject to the reporting requirements under Section 16(a) of the Exchange Act (i) he will not violate Section 16(b) of the Exchange Act, (ii) he will furnish the Company
with a copy of each Form 4 and Form 5 filed by him, and (iii) he will timely file all reports required under the federal securities laws. 
 13. Effective Date of Plan; Termination Date of Plan. The Plan shall be effective on the date the Plan has been approved by the Board and the shareholders of the Company. The Plan was adopted,
subject to shareholder approval, by the Board as of September 12, 2011. The Plan shall terminate on September 12, 2021, except as to Options previously granted and outstanding under the Plan at that time. No Options shall be granted after
the date on which the Plan terminates. In no event may the Option period exceed ten years from the date on which the Option is granted. The Plan may be abandoned or terminated at any earlier time by the affirmative vote of the holders of a majority
of the shares of Common Stock present, or represented, and entitled to vote at a meeting duly held in accordance with the applicable laws of the State of Colorado, except with respect to any Options then outstanding under the Plan. 

  
 -6-

 14. Withholding Taxes. The Option Agreement shall provide that the Company may take
such steps as it may deem necessary or appropriate for the withholding of any taxes which the Company is required by any law or regulation or any governmental authority, whether federal, state or local, domestic or foreign, to withhold in connection
with any Option including, but riot limited to, the withholding of all or any portion of any payment or the withholding of issuance of Option Shares upon the exercise of any Option. 

15. Change of Control. 
 (a) Notwithstanding any other provision of the Plan to the contrary, and unless and Option Agreement provides otherwise (or as may otherwise be required under Code Section 409A), in the event of a
Change of Control, all Options outstanding as of the date of such Change of Control shall become fully vested and exercisable, whether or not then otherwise vested and exercisable. 

(b) Notwithstanding the foregoing, in the event of a merger, share exchange, reorganization or other business combination affecting the
Company, the Board may, in its sole and absolute discretion, determine that any or all Options granted pursuant to the Plan shall not vest or become exercisable on an accelerated basis, if the Company or the surviving or acquiring corporation, as
the case may be, shall have taken such action, including but not limited to the assumption of Options granted under the Plan or the grant of substitute options (in either case, with substantially similar terms or equivalent economic benefits as
Options granted under the Plan), as in the opinion of the Board is equitable or appropriate to protect the rights and interests of participants under the Plan. 
 16. Restrictions. The Company may impose such restrictions on Options, shares and any other benefits underlying Options hereunder as it may deem advisable, including without limitation restrictions
under the federal securities laws, the requirements of any stock exchange or similar organization and any blue sky, state or foreign securities laws applicable to such securities. 

17. Other Provisions. The following provisions are also in effect under the Plan: 

(a) The use of a masculine gender in the Plan shall also include within its meaning the feminine, and the singular may include the
plural, and the plural may include the singular, unless the context clearly indicates to the contrary. 
 (b) Any expenses of
administering the plan shall be borne by the Company. 
 (c) This Plan shall be construed to be in addition to any and all other
compensation plans or programs. The adoption of the Plan by the shareholders of the Company shall not be construed as creating any limitations on the power or authority of the Board to adopt such other additional incentive or other compensation
arrangements as the Board may deem necessary or desirable. 
 (d) The corporate laws of the State of Colorado shall govern all
issues concerning the relative rights of the Company and its shareholders under the Plan. All other questions and obligations under the Plan shall be construed and enforced in accordance with the

  
 -7-

 
internal laws of the State of California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of California or any other jurisdiction) that would
cause the application of the laws of any jurisdiction other than the State of California. 
 (e) Notwithstanding anything to the
contrary contained in this Plan, this Plan is intended to comply with the California Corporate Securities Law of 1968 and the rules and regulations promulgated thereunder. 
 (f) If any provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and
enforced as if the illegal or invalid provision had not been included. 
 (g) Headings are given to the sections of this Plan
solely as a convenience to facilitate reference. The reference to any statute, regulation or other provision of law shall be construed to refer to any amendment to or successor of such provision of law. 

(h) The Plan shall be binding upon the Company, its successors and assigns, and Optionees, their executors, administrators and permitted
transferees and beneficiaries.
