 (1) PURPOSES. 
 (a) Eligible Option
Recipients.    The persons eligible to receive Options are the Non-Employee Directors of the Company. 
 (b)
Available Options.    The purpose of the Plan is to provide a means by which Non-Employee Directors may be given an opportunity to benefit from increases in value of the Common Stock through the granting of Nonstatutory Stock
Options. 
 (c) General Purpose.    The Company, by means of the Plan, seeks to retain the services of its
Non-Employee Directors, to secure and retain the services of new Non-Employee Directors and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Affiliates. 
 (2) DEFINITIONS. 
 (a)
“Affiliate” means any parent corporation or subsidiary corporation of the Company, whether now or hereafter existing, as those terms are defined in Sections 424(e) and (f), respectively, of the Code. 
 (b) “Annual Grant” means an Option granted annually to all Non-Employee Directors who meet the specified criteria
specified in subsection 6(b) of the Plan. 
 (c) “Annual Meeting” means the annual meeting of the stockholders
of the Company. 
 (d) “Board” means the Board of Directors of the Company. 
 (e) “Code” means the Internal Revenue Code of 1986, as amended. 
 (f) “Common Stock” means the common stock of the Company. 
 (g) “Company” means Telik, Inc., a Delaware corporation. 
 (h) “Consultant” means any person, including an advisor, (i) engaged by the Company or an Affiliate to render
consulting or advisory services and who is compensated for such services or (ii) who is a member of the Board of Directors of an Affiliate. However, the term “Consultant” shall not include either Directors of the Company who are not
compensated by the Company for their services as Directors or Directors of the Company who are merely paid a director’s fee by the Company for their services as Directors. 

 (i) “Continuous Service” means that the Optionholder’s service with
the Company or an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. The Optionholder’s Continuous Service shall not be deemed to have terminated merely because of a change in the capacity in which the
Optionholder renders service to the Company or an Affiliate as an Employee, Consultant or Director or a change in the entity for which the Optionholder renders such service, provided that there is no interruption or termination of the
Optionholder’s Continuous Service. For example, a change in status from a Non-Employee Director of the Company to a Consultant of an Affiliate or an Employee of the Company will not constitute an interruption of Continuous Service. The Board or
the Chief Executive Officer of the Company, in that party’s sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of any leave of absence approved by that party, including sick leave, military
leave or any other personal leave. 
 (j) “Director” means a member of the Board of Directors of the Company.

 (k) “Disability” means the permanent and total disability of a person within the meaning of
Section 22(e)(3) of the Code. 
 (l) “Employee” means any person employed by the Company or an Affiliate.
Mere service as a Director or payment of a director’s fee by the Company or an Affiliate shall not be sufficient to constitute “employment” by the Company or an Affiliate. 
 (m) “Exchange Act” means the Securities Exchange Act of 1934, as amended. 
 (n) “Fair Market Value” means, as of any date, the value of the Common Stock determined as follows: 
 (i) If the Common Stock is listed on any established stock exchange or traded on the Nasdaq National Market or the Nasdaq SmallCap
Market, the Fair Market Value of a share of Common Stock, unless otherwise determined by the Board, shall be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such exchange or market (or the exchange
or market with the greatest volume of trading in the Common Stock) on the day of determination (or if such day of determination does not fall on a market trading day, then the last market trading day prior to the day of determination), as reported
in The Wall Street Journal or such other source as the Board deems reliable. 
 (ii) In the absence of such
markets for the Common Stock, the Fair Market Value shall be determined in good faith by the Board. 
 (o) “Initial
Grant” means an Option granted to a Non-Employee Director who meets the criteria specified in subsection 6(a) of the Plan.

 (t) “Option” means a Nonstatutory Stock Option
granted pursuant to the Plan.

Optionholder evidencing the terms and conditions of an individual Option grant. Each Option Agreement shall be subject to the terms and conditions of the Plan. 

 (v) “Optionholder” means a person to whom an Option is granted pursuant to
the Plan or, if applicable, such other person who holds an outstanding Option. 
 (w) “Plan” means this Telik,
Inc. 2000 Non-Employee Directors’ Stock Option Plan. 
 (x) “Rule 16b-3” means Rule 16b-3 promulgated
under the Exchange Act or any successor to Rule 16b-3, as in effect from time to time. 
 (y) “Securities Act”
means the Securities Act of 1933, as amended. 
 (3) ADMINISTRATION. 
 (a) Administration by Board.    The Board shall administer the Plan. The Board may not delegate administration of the Plan to a
committee. 
 (b) Powers of Board.    The Board shall have the power, subject to, and within the limitations of,
the express provisions of the Plan: 
 (i) To determine the provisions of each Option to the extent not specified in
the Plan. 
 (ii) To construe and interpret the Plan and Options granted under it, and to establish, amend and revoke
rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Option Agreement, in a manner and to the extent it shall deem necessary or expedient to
make the Plan fully effective. 
 (iii) To amend the Plan or an Option as provided in Section 12. 
 (iv) Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best
interests of the Company that are not in conflict with the provisions of the Plan. 
 (c) Effect of Board’s
Decision.    All determinations, interpretations and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons. 
 (4) SHARES SUBJECT TO THE PLAN. 
 (a) Share Reserve.    Subject to the provisions of Section 11 relating to adjustments upon changes in the Common Stock,
the Common Stock that may be issued pursuant to Options shall not exceed in the aggregate six hundred thousand (600,000) shares of Common Stock. 
 (b) Reversion of Shares to the Share Reserve.    If any Option shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, the shares of
Common Stock not acquired under such Option shall revert to and again become available for issuance under the Plan. 
 (c) Source of
Shares.    The shares of Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 
 (5) ELIGIBILITY. 
 The Options as set forth in section 6 automatically shall be granted under the Plan to all
Non-Employee Directors. 
 (6) NON-DISCRETIONARY GRANTS. 
 (a) Initial Grants.    Without any further action of the Board, each Non-Employee Director shall be granted an Initial Grant as
follows: 
 (i) On the IPO Date, each person who is then a Non-Employee Director automatically shall be granted an
Initial Grant to purchase twenty thousand (20,000) shares of Common Stock on the terms and conditions set forth herein. 

 (ii) After the IPO Date, each person who is elected or appointed for the first
time to be a Non-Employee Director automatically shall, upon the date of his or her initial election or appointment to be a Non-Employee Director by the Board or stockholders of the Company, be granted an Initial Grant to purchase twenty thousand
(20,000) shares of Common Stock on the terms and conditions set forth herein. 
 (b) Annual
Grants.    Without any further action of the Board, on the day following each Annual Meeting commencing with the first Annual Meeting following the IPO Date, each person who is then a Non-Employee Director automatically shall
be granted an Annual Grant to purchase ten thousand (10,000) shares of Common Stock on the terms and conditions set forth herein; provided, however, that if the person has not been serving as a Non-Employee Director for the entire period
since the preceding Annual Meeting, then the number of shares subject to the Annual Grant shall be reduced pro rata for each full quarter prior to the date of grant during which such person did not serve as a Non-Employee Director. 
 (7) OPTION PROVISIONS. 
 Each Option shall be in such form and shall contain such terms and conditions as required by the Plan. Each Option shall contain such additional terms and conditions, not inconsistent with the Plan, as the Board shall deem appropriate. Each
Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 
 (a) Term.    No Option shall be exercisable after the expiration of ten (10) years from the date it was granted. 
 (b) Exercise Price.    The exercise price of each Option shall be one hundred percent (100%) of the Fair Market Value of
the stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption
or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code. 
 (c)
Consideration.    The purchase price of stock acquired pursuant to an Option may be paid, to the extent permitted by applicable statutes and regulations, in any combination of the following methods: 
 (i) By cash or check. 
 (ii) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery of already-owned shares of Common Stock either that the
Optionholder has held for the period required to avoid a charge to the Company’s reported earnings (generally six months) or that the Optionholder did not acquire, directly or indirectly from the Company, that are owned free and clear of any
liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. “Delivery” for these purposes shall include delivery to the Company of the Optionholder’s attestation of ownership of
such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, the Optionholder may not exercise the Option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law,
regulation or agreement restricting the redemption of the Company’s stock. 
 (iii) Provided that at the time of
exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results
in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. 
 (d) Transferability.    Each Option shall be transferable by will or by the laws of descent and distribution and, during the
lifetime of the Optionholder, only as described in the Option Agreement. However, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the
Optionholder, shall thereafter be entitled to exercise the Option. 

 (e) Exercise Schedule.    The Option shall be exercisable as the shares of
Common Stock subject to the Option vest. 
 (f) Vesting
Schedule.    Options shall vest as follows: (i) one fourth (1/4th) of the shares of Common Stock subject to the
Option shall vest one year after the date of the grant of the Option, and (ii) one forty-eighth (1/48th) of the shares of Common Stock
subject to the Option shall vest monthly thereafter over a period of three (3) years. 
 (g) Termination of Continuous
Service.    In the event an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder
was entitled to exercise it as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 
 (h) Extension of Termination Date.    If the exercise of the Option following the termination of the Optionholder’s
Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited at any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall
terminate on the earlier of (i) the expiration of the term of the Option set forth in subsection 7(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during
which the exercise of the Option would not be in violation of such registration requirements. 
 (i) Disability of
Optionholder.    In the event an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was
entitled to exercise it as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve (12) months following such termination or (ii) the expiration of the term of the Option as set
forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate. 
 (j) Death of Optionholder.    In the event (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies
within the three-month period after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise the Option as of the date of
death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on
the earlier of (1) the date eighteen (18) months following the date of death or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified
herein, the Option shall terminate. 
 (8) COVENANTS OF THE COMPANY. 
 (a) Availability of Shares.    During the terms of the Options, the Company shall keep available at all times the number of
shares of Common Stock required to satisfy such Options. 
 (b) Securities Law Compliance.    The Company shall
seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Options and to issue and sell shares of Common Stock upon exercise of the Options; provided, however, that this
undertaking shall not require the Company to register under the Securities Act the Plan, any Option or any stock issued or issuable pursuant to any such Option. If, after reasonable efforts, the Company is unable to obtain from any such regulatory
commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such
Options unless and until such authority is obtained. 

 (9) USE OF PROCEEDS FROM STOCK.

 Proceeds from the sale of stock pursuant to Options shall constitute general funds of the Company. 
 (10) MISCELLANEOUS. 
 (a)
Shareholder Rights.    No Optionholder shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to such Option unless and until such Optionholder has satisfied all
requirements for exercise of the Option pursuant to its terms. 
 (b) No Service Rights.    Nothing in the Plan or
any instrument executed or Option granted pursuant thereto shall confer upon any Optionholder any right to continue to serve the Company as a Non-Employee Director or shall affect the right of the Company or an Affiliate to terminate (i) the
employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (iii) the service of a Director
pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be. 
 (c) Investment Assurances.    The Company may require an Optionholder, as a condition of exercising or acquiring stock under
any Option, (i) to give written assurances satisfactory to the Company as to the Optionholder’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company
who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Option; and (ii) to give written
assurances satisfactory to the Company stating that the Optionholder is acquiring the stock subject to the Option for the Optionholder’s own account and not with any present intention of selling or otherwise distributing the stock. The
foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (iii) the issuance of the shares upon the exercise or acquisition of stock under the Option has been registered under a then currently
effective registration statement under the Securities Act or (iv) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable
securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not
limited to, legends restricting the transfer of the stock. 
 (d) Withholding Obligations.    The Optionholder may
satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of stock under an Option by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the
Optionholder by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold shares from the shares of the Common Stock otherwise issuable to the Optionholder as a result of the
exercise or acquisition of stock under the Option, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the Company owned and
unencumbered shares of the Common Stock. 
 (11) ADJUSTMENTS UPON CHANGES IN
STOCK. 
 (a) Capitalization Adjustments.    If any change is made in the stock subject to the
Plan, or subject to any Option, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the class(es) and maximum number of
securities subject both to the Plan pursuant to subsection 4(a) and to the nondiscretionary Options specified in Section 5, and the outstanding Options will be appropriately adjusted in the class(es) and number of securities and price per share
of stock subject to such outstanding Options. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction
“without receipt of consideration” by the Company.) 

 (b) Dissolution or Liquidation.    In the event of a dissolution or
liquidation of the Company, then all outstanding Options shall terminate immediately prior to such event. 
 (c) Change in
Control.    In the event of (i) a sale, lease or other disposition of all or substantially all of the securities or assets of the Company, (ii) a merger or consolidation in which the Company is not the surviving
corporation or (iii) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form
of securities, cash or otherwise, then any surviving corporation or acquiring corporation may assume any Options outstanding under the Plan or substitute similar Options (including an option to acquire the same consideration paid to the stockholders
in the transaction described in this subsection 11(c)) for those outstanding under the Plan. In the event any surviving corporation or acquiring corporation does not assume such Options or substitute similar Options for those outstanding under the
Plan, then with respect to Options held by Optionholders whose Continuous Service has not terminated, the vesting of such Options (and the time during which such Options may be exercised) shall be accelerated in full, and the Options shall terminate
if not exercised at or prior to such event. With respect to any other Options outstanding under the Plan, such Options shall terminate if not exercised prior to such event. 
 (12) AMENDMENT OF THE PLAN AND OPTIONS. 
 (a) Amendment of Plan.    The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 11 relating to adjustments upon changes in stock, no
amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of Rule 16b-3 or any Nasdaq or securities exchange listing requirements. 
 (b) Shareholder Approval.    The Board may, in its sole discretion, submit any other amendment to the Plan for stockholder
approval. 
 (c) No Impairment of Rights.    Rights under any Option granted before amendment of the Plan shall
not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing. 
 (d) Amendment of Options.    The Board at any time, and from time to time, may amend the terms of any one or more Options; provided, however, that the rights under any Option shall not be
impaired by any such amendment unless (i) the Company requests the consent of the Optionholder and (ii) the Optionholder consents in writing. 
 (13) TERMINATION OR SUSPENSION OF THE PLAN. 
 (a) Plan Term.    The Board may suspend or terminate the Plan at any
time. Unless sooner terminated, the Plan shall terminate on the day before the tenth (10th) anniversary of its adoption by the Board. No
Options may be granted under the Plan while the Plan is suspended or after it is terminated. 
 (b) No Impairment of
Rights.    Suspension or termination of the Plan shall not impair rights and obligations under any Option granted while the Plan is in effect except with the written consent of the Optionholder. 
 (14) EFFECTIVE DATE OF PLAN. 
 The Plan shall become effective on the IPO Date, but no Option shall be exercised unless and until the Plan has been approved by the stockholders of the
Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 
 (15) CHOICE
OF LAW. 
 All questions concerning the construction, validity and interpretation of this Plan shall be
governed by the law of the State of Delaware, without regard to such state’s conflict of laws rules.Amended and Restated 2004 Equity Incentive Plan

Rights, Restricted Stock Bonuses, Performance Shares, Performance Units, Restricted Stock Units and Deferred Compensation Awards. 
 1.3
Term of Plan. The Plan shall continue in effect until the earlier of its termination by the Board or the date on which all of the shares of Stock available for issuance under the Plan have been issued and all restrictions on such shares under
the terms of the Plan and the agreements evidencing Awards granted under the Plan have lapsed. However, all Awards shall be granted, if at all, within ten (10) years from the Effective Date.

 3.5 Powers of the Committee. In addition to any other powers set forth in the Plan and subject to
the provisions of the Plan, the Committee shall have the full and final power and authority, in its discretion: 
 (a) to
determine the persons to whom, and the time or times at which, Awards shall be granted and the number of shares of Stock or units to be subject to each Award; 
 (b) to determine the type of Award granted and to designate Options as Incentive Stock Options, Nonstatutory Stock Options or Indexed
Options;

 (d) to determine the terms, conditions and restrictions applicable to each Award (which need not be identical) and any shares acquired
pursuant thereto, including, without limitation, (i) the exercise or purchase price of shares purchased pursuant to any Award, (ii) the method of payment for shares purchased pursuant to any Award, (iii) the method for satisfaction of
any tax withholding obligation arising in connection with Award, including by the withholding or delivery of shares of Stock, (iv) the timing, terms and conditions of the exercisability or vesting of any Award or any shares acquired pursuant
thereto, (v) the Performance Award Formula and Performance Goals applicable to any Award and the extent to which such Performance Goals have been attained, (vi) the time of the expiration of any Award, (vii) the effect of the
Participant’s termination of Service on any of the foregoing, and (viii) all other terms, conditions and restrictions applicable to any Award or shares acquired pursuant thereto not inconsistent with the terms of the Plan;

combination thereof;

 (g) to amend, modify, extend, cancel or renew any Award or to waive any restrictions or conditions applicable to any Award or any shares
acquired pursuant thereto; 
 (h) to accelerate, continue, extend or defer the exercisability or vesting of any Award or any
shares acquired pursuant thereto, including with respect to the period following a Participant’s termination of Service; 
 (i) without the consent of the affected Participant and notwithstanding the provisions of any Award Agreement to the contrary, to unilaterally substitute at any time a Stock Appreciation Right providing for settlement solely in shares of
Stock in place of any outstanding Option, provided that such Stock Appreciation Right covers the same number of shares of Stock and provides for the same exercise price (subject in each case to adjustment in accordance with Section 4.4) as the
replaced Option and otherwise provides substantially equivalent terms and conditions as the replaced Option, as determined by the Committee; 
 (j) to prescribe, amend or rescind rules, guidelines and policies relating to the Plan, or to adopt sub-plans or supplements to, or alternative versions of, the Plan, including, without limitation, as the Committee
deems necessary or desirable to comply with the laws or 

  

 9 

 
regulations of or to accommodate the tax policy, accounting principles or custom of, foreign jurisdictions whose citizens may be granted Awards; and

 (k) to correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award Agreement and to
make all other determinations and take such other actions with respect to the Plan or any Award as the Committee may deem advisable to the extent not inconsistent with the provisions of the Plan or applicable law. 
 3.6 No Repricing. Without the affirmative vote of holders of a majority of the shares of Stock cast in person or by proxy at a meeting of the
stockholders of the Company at which a quorum representing a majority of all outstanding shares of Stock is present or represented by proxy, the Board shall not approve a program providing for the amendment of outstanding Options and/or SARs to
reduce the exercise price thereof. This paragraph shall not be construed to apply to (i) “issuing or assuming a stock option in a transaction to which section 424(a) applies,” within the meaning of Section 424 of the Code or
(ii) to any Option Exchange Program.

the Committee or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in
connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement
thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged
in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such
person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 
  

	4.	SHARES SUBJECT TO PLAN. 

 4.1 Maximum Number of Shares Issuable. Subject to adjustment as provided in Section 4.2 and Section 4.4, the maximum aggregate number of
shares of Stock that may be issued under the Plan shall be Sixteen Million (16,000,000), reduced at any time by the number of shares subject to the Prior Plan Options. Such shares shall consist of authorized but unissued or reacquired shares of
Stock or any combination thereof. If any outstanding Award, including any Prior Plan Options, for any reason, expires or is terminated or canceled without having been exercised or settled in full, or if shares of Stock acquired pursuant to an Award
subject to forfeiture or repurchase, including any Prior Plan Options, are forfeited or repurchased by the Company, the shares of Stock allocable to the terminated portion of such Award, including any Prior Plan Options, or such forfeited or
repurchased shares of Stock shall again be available for grant under the Plan. Notwithstanding anything in the Plan, or any Award Agreement to the contrary, shares underlying Options transferred under any Option Exchange Program described 

  

 10 

 
in Section 2.1(z)(i) shall not be again available for grant under the Plan. Shares of Stock shall not be deemed to have been issued pursuant to the Plan
(a) with respect to any portion of an Award that is settled in cash or (b) to the extent such shares are withheld or reacquired by the Company in satisfaction of tax withholding obligations pursuant to Section 16.2. Upon payment in
shares of Stock pursuant to the exercise of an SAR, the number of shares available for issuance under the Plan shall be reduced only by the number of shares actually issued in such payment. If the exercise price of an Option is paid by tender to the
Company, or attestation to the ownership, of shares of Stock owned by the Participant, the number of shares available for issuance under the Plan shall be reduced by the net number of shares for which the Option is exercised. 
 4.2 Annual Increase in Maximum Number of Shares Issuable. The maximum aggregate number of shares of Stock that may be issued under the Plan as set
forth in Section 4.1 shall be cumulatively increased on January 1, 2005 and on each subsequent January 1st, through and including January 1, 2013, by a number of shares (the “Annual Increase”) equal to the
smallest of (i) one and a half percent (1.5%) of the number of shares of Stock issued and outstanding on the immediately preceding December 31st, (ii) Seven Hundred and Fifty Thousand (750,000) shares or (iii) an amount
determined by the Board. 
 4.3 Maximum Number of Shares Issuable Pursuant to Incentive Stock Options. Subject to adjustment as
provided in Section 4.4, the maximum aggregate number of shares of Stock that may be issued under the Plan pursuant to the exercise of Incentive Stock Options (the “ISO Share Limit”) shall not exceed Sixteen Million
(16,000,000), cumulatively increased on January 1, 2005 and on each subsequent January 1st, through and including January 1, 2013, by a number of shares equal to the applicable Annual Increase. The maximum aggregate number of shares
of Stock that may be issued under the Plan pursuant to all Awards other than Incentive Stock Options shall be the number of shares determined in accordance with Section 4.1, subject to adjustment as provided in Section 4.2 and
Section 4.4. 
 4.4 Adjustments for Changes in Capital Structure. Subject to any required action by the stockholders of the
Company, in the event of any change in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of the Company in
a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of shares of Stock, appropriate adjustments shall be made in the number and kind of shares subject to the Plan and to any outstanding
Awards, in the ISO Share Limit set forth in Section 4.3, in the Nonemployee Director Options to be granted automatically pursuant to Section 7, the per-person annual Award limits set forth in Sections 6.6, 8.8, 9.9, 10.8 and 11.9, and in
the exercise or purchase price per share under any outstanding Award in order to prevent dilution or enlargement of Participants’ rights under the Plan. For purposes of the foregoing, conversion of any convertible securities of the Company
shall not be treated as “effected without receipt of consideration by the Company.” Any fractional share resulting from an adjustment pursuant to this Section 4.4 shall be rounded down to the nearest whole number, and in no event may
the exercise or purchase price under any Award be decreased to an amount less than the par value, if any, of the stock subject to such Award. The 

  

 11 

 
Committee in its sole discretion, may also make such adjustments in the terms of any Award to reflect, or related to, such changes in the capital structure
of the Company or distributions as it deems appropriate, including modification of Performance Goals, Performance Award Formulas and Performance Periods. The adjustments determined by the Committee pursuant to this Section 4.4 shall be final,
binding and conclusive. 
  

	5.	ELIGIBILITY AND AWARD LIMITATIONS. 

 5.1 Persons Eligible for Awards. Awards may be granted only to Employees, Consultants and Directors. For purposes of the foregoing sentence,
“Employees,” “Consultants” and “Directors” shall include prospective Employees, prospective Consultants and prospective Directors to whom Awards are granted in connection with written offers of an employment or other
service relationship with the Participating Company Group; provided, however, that no Stock subject to any such Award shall vest, become exercisable or be issued prior to the date on which such person commences Service. A Nonemployee Director Option
may be granted only to a person who, at the time of grant, is a Nonemployee Director. 
 5.2 Participation. Awards other than
Nonemployee Director Options are granted solely at the discretion of the Committee. Eligible persons may be granted more than one Award. However, excepting Nonemployee Director Options, eligibility in accordance with this Section shall not entitle
any person to be granted an Award, or, having been granted an Award, to be granted an additional Award. 
 5.3 Incentive Stock Option
Limitations. 
 (a) Persons Eligible. An Incentive Stock Option may be granted only to a person who, on the
effective date of grant, is an Employee of the Company, a Parent Corporation or a Subsidiary Corporation (each being an “ISO-Qualifying Corporation”). Any person who is not an Employee of an ISO-Qualifying Corporation on the
effective date of the grant of an Option to such person may be granted only a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective Employee upon the condition that such person become an Employee of an ISO-Qualifying
Corporation shall be deemed granted effective on the date such person commences Service with an ISO-Qualifying Corporation, with an exercise price determined as of such date in accordance with Section 6.1. 
 (b) Fair Market Value Limitation. To the extent that options designated as Incentive Stock Options (granted under all stock
option plans of the Participating Company Group, including the Plan) become exercisable by a Participant for the first time during any calendar year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the
portion of such options which exceeds such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section, options designated as Incentive Stock Options shall be taken into account in the order in which they were granted, and
the Fair Market Value of stock shall be determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a limitation different from that set forth in this Section, such different limitation shall be
deemed incorporated herein effective as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by
reason 

  

 12 

 
of the limitation set forth in this Section, the Participant may designate which portion of such Option the Participant is exercising. In the absence of such
designation, the Participant shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Upon exercise, shares issued pursuant to each such portion shall be separately identified. 
  

	6.	TERMS AND CONDITIONS OF OPTIONS. 

 Options shall be evidenced by Award Agreements specifying the number of shares of Stock covered thereby, in such form as the Committee shall from time to
time establish. No Option or purported Option shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Options may incorporate all or any of the terms of the Plan by
reference and, except as otherwise set forth in Section 7 with respect to Nonemployee Director Options, shall comply with and be subject to the following terms and conditions: 
 6.1 Exercise Price. The exercise price for each Option shall be established in the discretion of the Committee; provided, however, that
(a) the exercise price per share shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option, (b) no Incentive Stock Option granted to a Ten Percent Owner shall have an exercise price per
share less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option, and (c) notwithstanding anything to the contrary in this Section 6.1, in the case of an Indexed
Option, the Committee shall determine the exercise price of such Indexed Option and the terms and conditions that affect, if any, any adjustments to the exercise price of such Indexed Option; provided, however, that in no event shall the exercise
price of an Indexed Option be less than one hundred percent (100%) of the Fair Market Value of a share of Stock on the effective date of the grant of such Indexed Option. Notwithstanding the foregoing, an Option may be granted with an exercise
price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a manner qualifying under the provisions of Section 424(a) of the Code. 
 6.2 Exercisability and Term of Options. Options shall be exercisable at such time or times, or upon such event or events, and subject to such
terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award Agreement evidencing such Option; provided, however, that (a) no Option shall be exercisable after the expiration of ten
(10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Owner shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option,
and (c) no Option granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service. Subject to the foregoing, unless otherwise specified by the
Committee in the grant of an Option, any Option granted hereunder shall terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated in accordance with its provisions. 
 6.3 Payment of Exercise Price. 
 (a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of shares of Stock being purchased pursuant 

  

 13 

 
to any Option shall be made (i) in cash, by check or in cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of shares
of Stock owned by the Participant having a Fair Market Value not less than the exercise price, (iii) by delivery of a properly executed notice of exercise together with irrevocable instructions to a broker providing for the assignment to the
Company of the proceeds of a sale or loan with respect to some or all of the shares being acquired upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from
time to time by the Board of Governors of the Federal Reserve System) (a “Cashless Exercise”), (iv) by such other consideration as may be approved by the Committee from time to time to the extent permitted by applicable
law, or (v) by any combination thereof. The Committee may at any time or from time to time grant Options which do not permit all of the foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one
or more forms of consideration. 
 (b) Limitations on Forms of Consideration. 
 (i) Tender of Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company, or attestation to the
ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. Unless otherwise provided by the
Committee, an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Participant for more than six (6) months (and not used for another Option
exercise by attestation during such period) or were not acquired, directly or indirectly, from the Company. 
 (ii)
Cashless Exercise. The Company reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to establish, decline to approve or terminate any program or procedures for the exercise of Options by means of a
Cashless Exercise, including with respect to one or more Participants specified by the Company notwithstanding that such program or procedures may be available to other Participants. 
 6.4 Effect of Termination of Service. 
 (a) Option Exercisability. Subject to earlier termination of the Option as otherwise provided herein and unless otherwise provided by the Committee in the grant of an Option and set forth in the Award
Agreement, an Option shall be exercisable after a Participant’s termination of Service only during the applicable time period determined in accordance with this Section and thereafter shall terminate: 
 (i) Disability. If the Participant’s Service terminates because of the Disability of the Participant, the Option, to the
extent unexercised and exercisable on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of twelve
(12) months after the date on which the Participant’s Service terminated, but in any event no later than the date of expiration of the Option’s term as set forth in the Award Agreement evidencing such Option (the “Option
Expiration Date”). 
  

 14 

 (ii) Death. If the Participant’s Service terminates because of the death of
the Participant, the Option, to the extent unexercised and exercisable on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal representative or other person who acquired the right to exercise
the Option by reason of the Participant’s death at any time prior to the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. The
Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant’s termination of Service. 
 (iii) Termination for Cause. Notwithstanding any other provision of the Plan to the contrary, if the Participant’s Service is
terminated for Cause, the Option shall terminate and cease to be exercisable immediately upon such termination of Service. 
 (iv) Other Termination of Service. If the Participant’s Service terminates for any reason, except Disability, death or Cause, the Option, to the extent unexercised and exercisable by the Participant on the date on which the
Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of three (3) months after the date on which the Participant’s Service terminated, but in any event no later than the Option
Expiration Date. 
 (b) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, other than
termination of Service for Cause, if the exercise of an Option within the applicable time periods set forth in Section 6.4(a) is prevented by the provisions of Section 15 below, the Option shall remain exercisable until three
(3) months (or such longer period of time as determined by the Committee, in its discretion) after the date the Participant is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date.

 (c) Extension if Participant Subject to Section16(b). Notwithstanding the foregoing, other than termination
of Service for Cause, if a sale within the applicable time periods set forth in Section 6.4(a) of shares acquired upon the exercise of the Option would subject the Participant to suit under Section 16(b) of the Exchange Act, the Option
shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Participant would no longer be subject to such suit, (ii) the one hundred and ninetieth
(190th) day after the Participant’s termination of Service, or (iii) the Option Expiration Date. 
 6.5 Transferability of
Options. During the lifetime of the Participant, an Option shall be exercisable only by the Participant or the Participant’s guardian or legal representative. Prior to the issuance of shares of Stock upon the exercise of an Option, the
Option shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the
laws of descent and distribution. 
 Notwithstanding the foregoing, to the extent permitted by the Committee, in its discretion, an Option shall be
assignable or transferable subject to the applicable limitations, if any, described in the General Instructions to Form S-8 Registration Statement under the Securities Act. 

  

 15 

 
Notwithstanding any of the foregoing, the Committee may permit further transferability of any Option, on a general or specific basis, to third parties in
connection with an Option Exchange Program established and approved by the Committee pursuant to which Participant’s may receive a cash payment, or other consideration, in exchange for the transfer of such Option, and the Committee may impose
any conditions and limitations on any permitted transferability and may amend, without Participant consent, any outstanding Option as may be necessary to facilitate the transfer of such Option under any Option Exchange Program. 
 6.6 Individual Limit for Options. The maximum number of shares of Stock with respect to which Options may be granted to a Participant in any
calendar year shall be sixteen million (16,000,000) shares of Stock. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 4.4 above. To the extent
required by Section 162(m) of the Code or the regulations thereunder, in applying the foregoing limitation with respect to a Participant, if any Option is canceled, the canceled Option shall continue to count against the maximum number of
shares of Stock with respect to which Options may be granted to the Participant. For this purpose, the repricing of an Option shall be treated as the cancellation of the existing Option and the grant of a new Option. 
  

	7.	TERMS AND CONDITIONS OF NONEMPLOYEE DIRECTOR
OPTIONS. 

 Nonemployee Director Options shall be evidenced by Award Agreements specifying
the number of shares of Stock covered thereby, in such form as the Committee shall from time to time establish. Such Award Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the terms
and conditions of Section 6 to the extent not inconsistent with this Section and the following terms and conditions. 
 7.1 Grant of
Nonemployee Director Options. 
 (a) Initial Option. Subject to the execution by the Nonemployee Director of an
appropriate Award Agreement, each person who first becomes a Nonemployee Director on or after the Effective Date shall be granted automatically and without further action of the Committee on the date such person first becomes a Nonemployee Director
an Option (an “Initial Option”) to purchase Forty Thousand (40,000) shares of Stock. 
 (b)
Annual Option. Subject to the execution by the Nonemployee Director of an appropriate Award Agreement, each Nonemployee Director (including any Director who previously did not qualify as a Nonemployee Director but who subsequently
becomes a Nonemployee Director) shall be granted automatically and without further action of the Committee on the date of each annual meeting of the stockholders of the Company (the “Annual Meeting”), commencing with the
Annual Meeting held in 2005 and continuing for each Annual Meeting held thereafter during the term of the Plan, immediately following which such person remains a Nonemployee Director, an Option to purchase Ten Thousand (10,000) shares of Stock
(an “Annual Option”); provided, however, that a Nonemployee Director granted an Initial Option on, or within a period of six (6) months prior to, the date of an Annual Meeting shall not be granted an Annual Option
pursuant to this Section 7.1(b) with respect to the same Annual Meeting. 
  

 16 

 (c) Right to Decline Nonemployee Director Option. Notwithstanding the
foregoing, any person may elect not to receive a Nonemployee Director Option by delivering written notice of such election to the Board no later than the day prior to the date such Nonemployee Director Option would otherwise be granted. A person so
declining a Nonemployee Director Option shall receive no payment or other consideration in lieu of such declined Nonemployee Director Option. A person who has declined a Nonemployee Director Option may revoke such election by delivering written
notice of such revocation to the Board no later than the day prior to the date such Nonemployee Director Option would be granted pursuant to Section 7.1(a)or (b), as the case may be. 
 7.2 Exercise Price. The exercise price per share of Stock subject to a Nonemployee Director Option shall be the Fair Market Value of a share of
Stock on the date of grant of the Nonemployee Director Option. 
 7.3 Exercisability and Term of Nonemployee Director Options. Except
as otherwise provided in the Plan or in the Award Agreement evidencing a Nonemployee Director Option and provided that the Participant’s Service has not terminated prior to the relevant date, each Nonemployee Director Option shall vest and
become exercisable as set forth below and shall terminate and cease to be exercisable on the tenth (10th) anniversary of the date of grant of the Nonemployee Director Option, unless earlier terminated in accordance with the terms of the Plan or
the Award Agreement evidencing such Option. 
 (a) Initial Options. Twenty-five percent (25%) of each
Initial Option shall vest and become exercisable on the date one (1) year after the date of the Initial Option grant, and the remaining portion of the Initial Option shall vest and become exercisable quarterly thereafter at the rate of 6.25% of
the Initial Option for each quarter, provided that the Participant’s Service has not terminated prior to the relevant date. 
 (b) Annual Options. Twenty-five percent (25%) of each Annual Option shall vest and become exercisable on the date one (1) year after the date of the Annual l Option grant, and the remaining portion of the Annual
Option shall vest and become exercisable quarterly thereafter at the rate of 6.25% of the Annual Option for each quarter, provided that the Participant’s Service has not terminated prior to the relevant date. 
 7.4 Effect of Termination of Service. 
 (a) Option Exercisability. Subject to earlier termination of the Nonemployee Director Option as otherwise provided herein, a Nonemployee Director Option shall be exercisable after the Participant’s
termination of Service only during the applicable time period determined in accordance with this Section and thereafter shall terminate: 
 (i) Disability. If the Participant’s Service terminates because of the Disability of the Participant, the Nonemployee Director Option, to the extent unexercised and exercisable on the date on which the
Participant’s Service terminated, may be exercised by the Participant (or the Participant’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date on which the Participant’s
Service terminated, but in any event no later than the Option Expiration Date. 
  

 17 

 (ii) Death. If the Participant’s Service terminates because of the death of
the Participant, the Nonemployee Director Option, to the extent unexercised and exercisable on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal representative or other person who acquired
the right to exercise the Nonemployee Director Option by reason of the Participant’s death at any time prior to the expiration of twelve (12) months after the date on which the Participant’s Service terminated, but in any event no
later than the Option Expiration Date. The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies within three (3) months after the Participant’s termination of Service. 
 (iii) Other Termination of Service. If the Participant’s Service terminates for any reason, except Disability or death, the
Nonemployee Director Option, to the extent unexercised and exercisable by the Participant on the date on which the Participant’s Service terminated, may be exercised by the Participant at any time prior to the expiration of six (6) months
after the date on which the Participant’s Service terminated, but in any event no later than the Option Expiration Date. 
 (b) Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of a Nonemployee Director Option within the applicable time periods set forth in Section 7.4(a) is prevented by the provisions of
Section 15 below, the Nonemployee Director Option shall remain exercisable until three (3) months after the date the Participant is notified by the Company that the Nonemployee Director Option is exercisable, but in any event no later than
the Option Expiration Date. 
 (c) Extension if Participant Subject to Section16(b). Notwithstanding the
foregoing, if a sale within the applicable time periods set forth in Section 7.4(a) of shares acquired upon the exercise of the Nonemployee Director Option would subject the Participant to suit under Section 16(b) of the Exchange Act, the
Nonemployee Director Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Participant would no longer be subject to such suit, (ii) the one
hundred and ninetieth (190th) day after the Participant’s termination of Service, or (iii) the Option Expiration Date. 
  

	8.	TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS.

 Stock Appreciation Rights shall be evidenced by Award Agreements specifying the number of shares of Stock subject to the
Award, in such form as the Committee shall from time to time establish. No SAR or purported SAR shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing SARs may
incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 
 8.1 Types of SARs Authorized. SARs may be granted in tandem with all or any portion of a related Option (a “Tandem SAR”) or may be granted independently of any Option (a “Freestanding
SAR”). A Tandem SAR may be granted either concurrently with the grant of the related Option or at any time thereafter prior to the complete exercise, termination, expiration or cancellation of such related Option. 
  

 18 

 8.2 Base Appreciation Amount. The base appreciation amount for each SAR shall be established in
the discretion of the Committee; provided, however, that (a) the base appreciation amount per share subject to a Tandem SAR shall be the exercise price per share under the related Option and (b) the base appreciation amount per share
subject to a Freestanding SAR shall be not less than the Fair Market Value of a share of Stock on the effective date of grant of the SAR. 
 8.3 Exercisability and Term of SARs. 
 (a) Tandem SARs. Tandem SARs shall be exercisable only at the
time and to the extent, and only to the extent, that the related Option is exercisable, subject to such provisions as the Committee may specify where the Tandem SAR is granted with respect to less than the full number of shares of Stock subject to
the related Option. The Committee may, in its discretion, provide in any Award Agreement evidencing a Tandem SAR that such SAR may not be exercised without the advance approval of the Company and, if such approval is not given, then the Option shall
nevertheless remain exercisable in accordance with its terms. A Tandem SAR shall terminate and cease to be exercisable no later than the date on which the related Option expires or is terminated or canceled. Upon the exercise of a Tandem SAR with
respect to some or all of the shares subject to such SAR, the related Option shall be canceled automatically as to the number of shares with respect to which the Tandem SAR was exercised. Upon the exercise of an Option related to a Tandem SAR as to
some or all of the shares subject to such Option, the related Tandem SAR shall be canceled automatically as to the number of shares with respect to which the related Option was exercised. 
 (b) Freestanding SARs. Freestanding SARs shall be exercisable at such time or times, or upon such event or events, and
subject to such terms, conditions, performance criteria and restrictions as shall be determined by the Committee and set forth in the Award Agreement evidencing such SAR; provided, however, that no Freestanding SAR shall be exercisable after the
expiration of ten (10) years after the effective date of grant of such SAR. 
 8.4 Exercise of SARs. Upon the exercise (or deemed
exercise pursuant to Section 8.5) of an SAR, the Participant (or the Participant’s legal representative or other person who acquired the right to exercise the SAR by reason of the Participant’s death) shall be entitled to receive
payment of an amount for each share with respect to which the SAR is exercised equal to the excess, if any, of the Fair Market Value of a share of Stock on the date of exercise of the SAR over the base appreciation amount. Payment of such amount
shall be made in cash, shares of Stock, or any combination thereof as determined by the Committee. Unless otherwise provided in the Award Agreement evidencing such SAR, payment shall be made in a lump sum as soon as practicable following the date of
exercise of the SAR. The Award Agreement evidencing any SAR may provide for deferred payment in a lump sum or in installments. When payment is to be made in shares of Stock, the number of shares to be issued shall be determined on the basis of the
Fair Market Value of a share of Stock on the date of exercise of the SAR. For purposes of Section 8, an SAR shall be deemed exercised on the date on which the Company receives notice of exercise from the Participant or as otherwise provided in
Section 8.5. 
 8.5 Deemed Exercise of SARs. If, on the date on which an SAR would otherwise terminate or expire, the SAR by its
terms remains exercisable immediately prior to such 

  

 19 

 
termination or expiration and, if so exercised, would result in a payment to the holder of such SAR, then any portion of such SAR which has not previously
been exercised shall automatically be deemed to be exercised as of such date with respect to such portion. 
 8.6 Effect of Termination of
Service. Subject to earlier termination of the SAR as otherwise provided herein and unless otherwise provided by the Committee in the grant of an SAR and set forth in the Award Agreement, an SAR shall be exercisable after a Participant’s
termination of Service only during the applicable time period determined in accordance with Section 6.4 (treating the SAR as if it were an Option) and thereafter shall terminate. 
 8.7 Nontransferability of SARs. During the lifetime of the Participant, a SAR shall be exercisable only by the Participant or the
Participant’s guardian or legal representative. Prior to the exercise of a SAR, the SAR shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of
the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. Notwithstanding any of the foregoing, the Board may permit further transferability of any SAR, on a general or specific basis,
and may impose conditions and limitations on any permitted transferability. 
 8.8 Individual Limit for SARs. The maximum number of
shares of Stock with respect to which SARs may be granted to a Participant in any calendar year shall be sixteen million (16,000,000) shares of Stock. The foregoing limitation shall be adjusted proportionately in connection with any change in
the Company’s capitalization pursuant to Section 4.4 above. To the extent required by Section 162(m) of the Code or the regulations thereunder, in applying the foregoing limitation with respect to a Participant, if any SAR is
canceled, the canceled SAR shall continue to count against the maximum number of shares of Stock with respect to which SARs may be granted to the Participant. For this purpose, the base amount on which the stock appreciation is calculated is reduced
to reflect a reduction in the Fair Market Value of the Common Stock shall be treated as the cancellation of the existing SAR and the grant of a new SAR. 
  

	9.	TERMS AND CONDITIONS OF RESTRICTED STOCK AWARDS.

 Restricted Stock Awards shall be evidenced by Award Agreements specifying whether the Award is a Restricted Stock Bonus or a
Restricted Stock Purchase Right and the number of shares of Stock subject to the Award, in such form as the Committee shall from time to time establish. No Restricted Stock Award or purported Restricted Stock Award shall be a valid and binding
obligation of the Company unless evidenced by a fully executed Award Agreement. Award Agreements evidencing Restricted Stock Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the
following terms and conditions: 
 9.1 Types of Restricted Stock Awards Authorized. Restricted Stock Awards may be in the form of
either a Restricted Stock Bonus or a Restricted Stock Purchase Right. Restricted Stock Awards may be granted upon such conditions as the Committee shall determine, including, without limitation, upon the attainment of one or more Performance Goals
described in Section 11.4. If either the grant of a Restricted Stock Award or the lapsing of the Restriction 

  

 20 

 
Period is to be contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures substantially equivalent to those set
forth in Sections 11.3 through 11.5(a). 
 9.2 Purchase Price. The purchase price for shares of Stock issuable under each Restricted
Stock Purchase Right shall be established by the Committee in its discretion. No monetary payment (other than applicable tax withholding) shall be required as a condition of receiving shares of Stock pursuant to a Restricted Stock Bonus, the
consideration for which shall be services actually rendered to a Participating Company or for its benefit. Notwithstanding the foregoing, the Participant shall furnish consideration in the form of cash or past services rendered to a Participating
Company or for its benefit having a value not less than the par value of the shares of Stock subject to such Restricted Stock Award. 
 9.3
Purchase Period. A Restricted Stock Purchase Right shall be exercisable within a period established by the Committee, which shall in no event exceed thirty (30) days from the effective date of the grant of the Restricted Stock Purchase
Right; provided, however, that no Restricted Stock Purchase Right granted to a prospective Employee, prospective Consultant or prospective Director may become exercisable prior to the date on which such person commences Service. 
 9.4 Payment of Purchase Price. Except as otherwise provided below, payment of the purchase price for the number of shares of Stock being purchased
pursuant to any Restricted Stock Purchase Right shall be made (a) in cash, by check, or in cash equivalent, (b) by such other consideration as may be approved by the Committee from time to time to the extent permitted by applicable law, or
(iii) by any combination thereof. The Committee may at any time or from time to time grant Restricted Stock Purchase Rights which do not permit all of the foregoing forms of consideration to be used in payment of the purchase price or which
otherwise restrict one or more forms of consideration. Restricted Stock Bonuses shall be issued in consideration for past services actually rendered to a Participating Company or for its benefit. 
 9.5 Vesting and Restrictions on Transfer. Shares issued pursuant to any Restricted Stock Award may or may not be made subject to Vesting
Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including, without limitation, Performance Goals as described in Section 11.4, as shall be established by the Committee and
set forth in the Award Agreement evidencing such Award. During any Restriction Period in which shares acquired pursuant to a Restricted Stock Award remain subject to Vesting Conditions, such shares may not be sold, exchanged, transferred, pledged,
assigned or otherwise disposed of other than pursuant to an Ownership Change Event, as defined in Section 2.1(aa), or as provided in Section 9.8. Upon request by the Company, each Participant shall execute any agreement evidencing such
transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends
evidencing any such transfer restrictions. 
 9.6 Voting Rights; Dividends and Distributions. Except as provided in this Section,
Section 9.5 and any Award Agreement, during the Restriction Period applicable to shares subject to a Restricted Stock Award, the Participant shall have all of the rights of a 

  

 21 

 
stockholder of the Company holding shares of Stock, including the right to vote such shares and to receive all dividends and other distributions paid with
respect to such shares. However, in the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.4, any and all new, substituted or
additional securities or other property (other than normal cash dividends) to which the Participant is entitled by reason of the Participant’s Restricted Stock Award shall be immediately subject to the same Vesting Conditions as the shares
subject to the Restricted Stock Award with respect to which such dividends or distributions were paid or adjustments were made. 
 9.7
Effect of Termination of Service. Unless otherwise provided by the Committee in the grant of a Restricted Stock Award and set forth in the Award Agreement, if a Participant’s Service terminates for any reason, whether voluntary or
involuntary (including the Participant’s death or disability), then (a) the Company shall have the option to repurchase for the purchase price paid by the Participant any shares acquired by the Participant pursuant to a Restricted Stock
Purchase Right which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service and (b) the Participant shall forfeit to the Company any shares acquired by the Participant pursuant to a Restricted Stock
Bonus which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable,
to one or more persons as may be selected by the Company. 
 9.8 Nontransferability of Restricted Stock Award Rights. Prior to the
issuance of shares of Stock pursuant to a Restricted Stock Award, rights to acquire such shares shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance or garnishment by creditors of
the Participant or the Participant’s beneficiary, except transfer by will or the laws of descent and distribution. All rights with respect to a Restricted Stock Award granted to a Participant hereunder shall be exercisable during his or her
lifetime only by such Participant or the Participant’s guardian or legal representative. 
 9.9 Individual Limit for Restricted
Stock. For Restricted Stock Awards subject to Vesting Conditions based on the attainment of Performance Goals, the maximum number of shares of Stock with respect to which such Awards may be granted to a Participant in any calendar year shall be
sixteen million (16,000,000) shares of Stock. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 4.4 above. 
  

 22 

	10.	TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT
AWARDS. 

 Restricted Stock Unit Awards shall be evidenced by Award Agreements specifying the number of
Restricted Stock Units subject to the Award, in such form as the Committee shall from time to time establish. No Restricted Stock Unit Award or purported Restricted Stock Unit Award shall be a valid and binding obligation of the Company unless
evidenced by a fully executed Award Agreement. Award Agreements evidencing Restricted Stock Units may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

 10.1 Grant of Restricted Stock Unit Awards. Restricted Stock Unit Awards may be granted upon such conditions as the Committee shall
determine, including, without limitation, upon the attainment of one or more Performance Goals described in Section 11.4. If either the grant of a Restricted Stock Unit Award or the Vesting Conditions with respect to such Award is to be
contingent upon the attainment of one or more Performance Goals, the Committee shall follow procedures substantially equivalent to those set forth in Sections 11.3 through 11.5(a). 
 10.2 Purchase Price. No monetary payment (other than applicable tax withholding, if any) shall be required as a condition of receiving a
Restricted Stock Unit Award, the consideration for which shall be services actually rendered to a Participating Company or for its benefit. 
 10.3 Vesting. Restricted Stock Units may or may not be made subject to Vesting Conditions based upon the satisfaction of such Service requirements, conditions, restrictions or performance criteria, including, without limitation,
Performance Goals as described in Section 11.4, as shall be established by the Committee and set forth in the Award Agreement evidencing such Award. 
 10.4 Voting Rights, Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of Stock represented by Restricted Stock Units until the date of the issuance of
such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). However, the Committee, in its discretion, may provide in the Award Agreement evidencing any Restricted Stock Unit
Award that the Participant shall be entitled to receive Dividend Equivalents with respect to the payment of cash dividends on Stock having a record date prior to date on which Restricted Stock Units held by such Participant are settled. Such
Dividend Equivalents, if any, shall be paid by crediting the Participant with additional whole Restricted Stock Units as of the date of payment of such cash dividends on Stock. The number of additional Restricted Stock Units (rounded to the nearest
whole number) to be so credited shall be determined by dividing (a) the amount of cash dividends paid on such date with respect to the number of shares of Stock represented by the Restricted Stock Units previously credited to the Participant by
(b) the Fair Market Value per share of Stock on such date. Such additional Restricted Stock Units shall be subject to the same terms and conditions and shall be settled in the same manner and at the same time (or as soon thereafter as
practicable) as the Restricted Stock Units originally subject to the Restricted Stock Unit Award. In the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company
as described in Section 4.4, appropriate adjustments shall be made in the Participant’s Restricted Stock Unit 

  

 23 

 
Award so that it represents the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal
cash dividends) to which the Participant would entitled by reason of the shares of Stock issuable upon settlement of the Award, and all such new, substituted or additional securities or other property shall be immediately subject to the same Vesting
Conditions as are applicable to the Award. 
 10.5 Effect of Termination of Service. Unless otherwise provided by the Committee in the
grant of a Restricted Stock Unit Award and set forth in the Award Agreement, if a Participant’s Service terminates for any reason, whether voluntary or involuntary (including the Participant’s death or disability), then the Participant
shall forfeit to the Company any Restricted Stock Units pursuant to the Award which remain subject to Vesting Conditions as of the date of the Participant’s termination of Service. 
 10.6 Settlement of Restricted Stock Unit Awards. The Company shall issue to a Participant on the date on which Restricted Stock Units subject to
the Participant’s Restricted Stock Unit Award vest or on such other date determined by the Committee, in its discretion, and set forth in the Award Agreement one (1) share of Stock (and/or any other new, substituted or additional
securities or other property pursuant to an adjustment described in Section 10.4) for each Restricted Stock Unit then becoming vested or otherwise to be settled on such date, subject to the withholding of applicable taxes. Notwithstanding the
foregoing, if permitted by the Committee and set forth in the Award Agreement, the Participant may elect in accordance with terms specified in the Award Agreement to defer receipt of all or any portion of the shares of Stock or other property
otherwise issuable to the Participant pursuant to this Section. 
 10.7 Nontransferability of Restricted Stock Unit Awards. Prior to
the issuance of shares of Stock in settlement of a Restricted Stock Unit Award, the Award shall not be subject in any manner to anticipation, alienation, sale, exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the
Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to a Restricted Stock Unit Award granted to a Participant hereunder shall be exercisable during his or her
lifetime only by such Participant or the Participant’s guardian or legal representative. 
 10.8 Individual Limit for Restricted
Stock Unit Awards. For Restricted Stock Unit Awards subject to Vesting Conditions based on the attainment of Performance Goals, the maximum number of shares of Stock with respect to which such Awards may be granted to a Participant in any
calendar year shall be sixteen million (16,000,000) shares of Stock. The foregoing limitation shall be adjusted proportionately in connection with any change in the Company’s capitalization pursuant to Section 4.4 above. 

 

	11.	TERMS AND CONDITIONS OF PERFORMANCE
AWARDS. 

 Performance Awards shall be evidenced by Award
Agreements in such form as the Committee shall from time to time establish. No Performance Award or purported Performance Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement. Award
Agreements evidencing Performance Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions: 
  

 24 

 11.1 Types of Performance Awards Authorized. Performance Awards may be in the form of either
Performance Shares or Performance Units. Each Award Agreement evidencing a Performance Award shall specify the number of Performance Shares or Performance Units subject thereto, the Performance Award Formula, the Performance Goal(s) and Performance
Period applicable to the Award, and the other terms, conditions and restrictions of the Award. 
 11.2 Initial Value of Performance Shares
and Performance Units. Unless otherwise provided by the Committee in granting a Performance Award, each Performance Share shall have an initial value equal to the Fair Market Value of one (1) share of Stock, subject to adjustment as
provided in Section 4.4, on the effective date of grant of the Performance Share, and each Performance Unit shall have an initial value of one hundred dollars ($100). The final value payable to the Participant in settlement of a Performance
Award determined on the basis of the applicable Performance Award Formula will depend on the extent to which Performance Goals established by the Committee are attained within the applicable Performance Period established by the Committee.

 11.3 Establishment of Performance Period, Performance Goals and Performance Award Formula. In granting each Performance Award, the
Committee shall establish in writing the applicable Performance Period, Performance Award Formula and one or more Performance Goals which, when measured at the end of the Performance Period, shall determine on the basis of the Performance Award
Formula the final value of the Performance Award to be paid to the Participant. Unless otherwise permitted in compliance with the requirements under Section 162(m) with respect to “performance-based compensation,” the Committee shall
establish the Performance Goal(s) and Performance Award Formula applicable to each Performance Award no later than the earlier of (a) the date ninety (90) days after the commencement of the applicable Performance Period or (b) the
date on which 25% of the Performance Period has elapsed, and, in any event, at a time when the outcome of the Performance Goals remains substantially uncertain. Once established, the Performance Goals and Performance Award Formula shall not be
changed during the Performance Period. The Company shall notify each Participant granted a Performance Award of the terms of such Award, including the Performance Period, Performance Goal(s) and Performance Award Formula. 
 11.4 Measurement of Performance Goals. Performance Goals shall be established by the Committee on the basis of targets to be attained
(“Performance Targets”) with respect to one or more measures of business or financial performance (each, a “Performance Measure”), subject to the following: 
 (a) Performance Measures. Performance Measures shall have the same meanings as used in the Company’s financial
statements, or, if such terms are not used in the Company’s financial statements, they shall have the meaning applied pursuant to generally accepted accounting principles, or as used generally in the Company’s industry. Performance
Measures shall be calculated with respect to the Company and each Subsidiary Corporation consolidated therewith for financial reporting purposes or such division or other business unit as may be selected by the Committee. For purposes of the Plan,
the Performance Measures applicable to a Performance Award shall be calculated in accordance with generally accepted accounting principles, but prior to the accrual or payment of any Performance Award for the same Performance Period and excluding
the effect (whether positive or negative) of any change 

  

 25 

 
in accounting standards or any extraordinary, unusual or nonrecurring item, as determined by the Committee, occurring after the establishment of the
Performance Goals applicable to the Performance Award. Each such adjustment, if any, shall be made solely for the purpose of providing a consistent basis from period to period for the calculation of Performance Measures in order to prevent the
dilution or enlargement of the Participant’s rights with respect to a Performance Award. Performance Measures may be one or more of the following, as determined by the Committee: 
 (i) sales revenue; 
 (ii) gross margin;

 (iii) operating margin; 
 (iv)
operating income; 
 (v) pre-tax profit; 
 (vi) earnings before interest, taxes and depreciation, and amortization; 
 (vii) net income; 
 (viii) expenses; 
 (ix) the market price of
the Stock; 
 (x) earnings per share; 
 (xi) return on stockholder equity; 
 (xii) return on capital; 
 (xiii) return on net assets; 
 (xiv) economic
value added; 
 (xv) number of customers; and 
 (xvi) market share. 
 (b) Performance Targets. Performance Targets may include
a minimum, maximum, target level and intermediate levels of performance, with the final value of a Performance Award determined under the applicable Performance Award Formula by the level attained during the applicable Performance Period. A
Performance Target may be stated as an absolute value or as a value determined relative to a standard selected by the Committee. 
 11.5
Settlement of Performance Awards. 
  

 26 

 (a) Determination of Final Value. As soon as practicable following the
completion of the Performance Period applicable to a Performance Award, the Committee shall certify in writing the extent to which the applicable Performance Goals have been attained and the resulting final value of the Award earned by the
Participant and to be paid upon its settlement in accordance with the applicable Performance Award Formula. 
 (b)
Discretionary Adjustment of Award Formula. In its discretion, the Committee may, either at the time it grants a Performance Award or at any time thereafter, provide for the positive or negative adjustment of the Performance Award
Formula applicable to a Performance Award granted to any Participant who is not a “covered employee” within the meaning of Section 162(m) (a “Covered Employee”) to reflect such Participant’s individual
performance in his or her position with the Company or such other factors as the Committee may determine. The Committee shall have the discretion, on the basis of such criteria as may be established by the Committee, to reduce some or all of the
value of the Performance Award that would otherwise be paid to the Covered Employee upon its settlement notwithstanding the attainment of any Performance Goal and the resulting value of the Performance Award determined in accordance with the
Performance Award Formula. No such reduction may result in an increase in the amount payable upon settlement of another Participant’s Performance Award. 
 (c) Effect of Leaves of Absence. Unless otherwise required by law, payment of the final value, if any, of a Performance
Award held by a Participant who has taken in excess of thirty (30) days in leaves of absence during a Performance Period shall be prorated on the basis of the number of days of the Participant’s Service during the Performance Period during
which the Participant was not on a leave of absence. 
 (d) Notice to Participants. As soon as practicable
following the Committee’s determination and certification in accordance with Sections 11.5(a) and (b), the Company shall notify each Participant of the determination of the Committee. 
 (e) Payment in Settlement of Performance Awards. As soon as practicable following the Committee’s determination and
certification in accordance with Sections 11.5(a) and (b), payment shall be made to each eligible Participant (or such Participant’s legal representative or other person who acquired the right to receive such payment by reason of the
Participant’s death) of the final value of the Participant’s Performance Award. Payment of such amount shall be made in cash, shares of Stock, or a combination thereof as determined by the Committee. Unless otherwise provided in the Award
Agreement evidencing a Performance Award, payment shall be made in a lump sum. An Award Agreement may provide for deferred payment in a lump sum or in installments. If any payment is to be made on a deferred basis, the Committee may, but shall not
be obligated to, provide for the payment during the deferral period of Dividend Equivalents or interest. 
 (f)
Provisions Applicable to Payment in Shares. If payment is to be made in shares of Stock, the number of such shares shall be determined by dividing the final value of the Performance Award by the value of a share of Stock determined by
the method specified in the Award Agreement. Such methods may include, without limitation, the closing market price on a specified date (such as the settlement date) or an average of market prices over a series of trading 

  

 27 

 
days. Shares of Stock issued in payment of any Performance Award may be fully vested and freely transferable shares or may be shares of Stock subject to
Vesting Conditions as provided in Section 9.5. Any shares subject to Vesting Conditions shall be evidenced by an appropriate Award Agreement and shall be subject to the provisions of Sections 9.5 through 9.8 above. 
 11.6 Voting Rights; Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of Stock
represented by Performance Share Awards until the date of the issuance of such shares, if any (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). However, the Committee, in its
discretion, may provide in the Award Agreement evidencing any Performance Share Award that the Participant shall be entitled to receive Dividend Equivalents with respect to the payment of cash dividends on Stock having a record date prior to the
date on which the Performance Shares are settled or forfeited. Such Dividend Equivalents, if any, shall be credited to the Participant in the form of additional whole Performance Shares as of the date of payment of such cash dividends on Stock. The
number of additional Performance Shares (rounded to the nearest whole number) to be so credited shall be determined by dividing (a) the amount of cash dividends paid on such date with respect to the number of shares of Stock represented by the
Performance Shares previously credited to the Participant by (b) the Fair Market Value per share of Stock on such date. Dividend Equivalents may be paid currently or may be accumulated and paid to the extent that Performance Shares become
nonforfeitable, as determined by the Committee. Settlement of Dividend Equivalents may be made in cash, shares of Stock, or a combination thereof as determined by the Committee, and may be paid on the same basis as settlement of the related
Performance Share as provided in Section 11.5. Dividend Equivalents shall not be paid with respect to Performance Units. In the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the
capital structure of the Company as described in Section 4.4, appropriate adjustments shall be made in the Participant’s Performance Share Award so that it represents the right to receive upon settlement any and all new, substituted or
additional securities or other property (other than normal cash dividends) to which the Participant would entitled by reason of the shares of Stock issuable upon settlement of the Performance Share Award, and all such new, substituted or additional
securities or other property shall be immediately subject to the same Performance Goals as are applicable to the Award. 
 11.7 Effect of
Termination of Service. Unless otherwise provided by the Committee in the grant of a Performance Award and set forth in the Award Agreement, the effect of a Participant’s termination of Service on the Performance Award shall be as follows:

 (a) Death or Disability. If the Participant’s Service terminates because of the death or Disability of
the Participant before the completion of the Performance Period applicable to the Performance Award, the final value of the Participant’s Performance Award shall be determined by the extent to which the applicable Performance Goals have been
attained with respect to the entire Performance Period and shall be prorated based on the number of months of the Participant’s Service during the Performance Period. Payment shall be made following the end of the Performance Period in any
manner permitted by Section 11.5. 
  

 28 

 (b) Other Termination of Service. If the Participant’s Service
terminates for any reason except death or Disability before the completion of the Performance Period applicable to the Performance Award, such Award shall be forfeited in its entirety; provided, however, that in the event of an involuntary
termination of the Participant’s Service, the Committee, in its sole discretion, may waive the automatic forfeiture of all or any portion of any such Award. 
 11.8 Nontransferability of Performance Awards. Prior to settlement in accordance with the provisions of the Plan, no Performance Award shall be subject in any manner to anticipation, alienation, sale, exchange,
transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to a Performance Award
granted to a Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal representative. 
 11.9 Limits on Performance Shares and Performance Units. Subject to adjustment as provided in Section 4.4, no Participant shall be granted (i) Performance Shares which could result in such Participant
receiving more than sixteen million (16,000,000) shares of Stock for each calendar year of the Company contained in the Performance Period for such Award, or (ii) Performance Units which could result in such Participant receiving more than
$5,000,000 for each calendar year of the Company contained in the Performance Period for such Award. No Participant may be granted more than one Performance Award for the same Performance Period. 
  

	12.	DEFERRED COMPENSATION AWARDS. 

 12.1 Establishment of Deferred Compensation Award Programs. This Section 12 shall not be effective unless and until the Committee determines to establish a program pursuant to this Section. The Committee,
in its discretion and upon such terms and conditions as it may determine, may establish one or more programs pursuant to the Plan under which: 
 (a) Participants designated by the Committee who are Insiders or otherwise among a select group of highly compensated Employees may irrevocably elect, prior to a date specified by the Committee, to reduce such
Participant’s compensation otherwise payable in cash (subject to any minimum or maximum reductions imposed by the Committee) and to be granted automatically at such time or times as specified by the Committee one or more Awards of Stock Units
with respect to such numbers of shares of Stock as determined in accordance with the rules of the program established by the Committee and having such other terms and conditions as established by the Committee. 
 (b) Participants designated by the Committee who are Insiders or otherwise among a select group of highly compensated Employees may
irrevocably elect, prior to a date specified by the Committee, to be granted automatically an Award of Stock Units with respect to such number of shares of Stock and upon such other terms and conditions as established by the Committee in lieu of:

 (i) shares of Stock otherwise issuable to such Participant upon the exercise of an Option; 
  

 29 

 (ii) cash or shares of Stock otherwise issuable to such Participant upon the exercise of
an SAR; or 
 (iii) cash or shares of Stock otherwise issuable to such Participant upon the settlement of a Performance Award.

 12.2 Terms and Conditions of Deferred Compensation Awards. Deferred Compensation Awards granted pursuant to this Section 12
shall be evidenced by Award Agreements in such form as the Committee shall from time to time establish. No such Deferred Compensation Award or purported Deferred Compensation Award shall be a valid and binding obligation of the Company unless
evidenced by a fully executed Award Agreement. Award Agreements evidencing Deferred Compensation Awards may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

 (a) Vesting Conditions. Deferred Compensation Awards shall not be subject to any vesting conditions.

 (b) Terms and Conditions of Stock Units. 
 (i) Voting Rights; Dividend Equivalent Rights and Distributions. Participants shall have no voting rights with respect to shares of
Stock represented by Stock Units until the date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). However, a Participant shall be entitled to
receive Dividend Equivalents with respect to the payment of cash dividends on Stock having a record date prior to date on which Stock Units held by such Participant are settled. Such Dividend Equivalents shall be paid by crediting the Participant
with additional whole and/or fractional Stock Units as of the date of payment of such cash dividends on Stock. The method of determining the number of additional Stock Units to be so credited shall be specified by the Committee and set forth in the
Award Agreement. Such additional Stock Units shall be subject to the same terms and conditions and shall be settled in the same manner and at the same time (or as soon thereafter as practicable) as the Stock Units originally subject to the Stock
Unit Award. In the event of a dividend or distribution paid in shares of Stock or any other adjustment made upon a change in the capital structure of the Company as described in Section 4.4, appropriate adjustments shall be made in the
Participant’s Stock Unit Award so that it represent the right to receive upon settlement any and all new, substituted or additional securities or other property (other than normal cash dividends) to which the Participant would entitled by
reason of the shares of Stock issuable upon settlement of the Award. 
 (ii) Settlement of Stock Unit Awards. A
Participant electing to receive an Award of Stock Units pursuant to this Section 12, shall specify at the time of such election a settlement date with respect to such Award. The Company shall issue to the Participant as soon as practicable
following the earlier of the settlement date elected by the Participant or the date of termination of the Participant’s Service, a number of whole shares of Stock equal to the number of whole Stock Units subject to the Stock Unit Award. Such
shares of Stock shall be fully vested, and the Participant shall not be required to pay any additional 

  

 30 

 
consideration (other than applicable tax withholding) to acquire such shares. Any fractional Stock Unit subject to the Stock Unit Award shall be settled by
the Company by payment in cash of an amount equal to the Fair Market Value as of the payment date of such fractional share. 
 (iii) Nontransferability of Stock Unit Awards. Prior to their settlement in accordance with the provision of the Plan, no Stock Unit Award shall be subject in any manner to anticipation, alienation, sale, exchange, transfer,
assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except transfer by will or by the laws of descent and distribution. All rights with respect to a Stock Unit Award granted to a
Participant hereunder shall be exercisable during his or her lifetime only by such Participant or the Participant’s guardian or legal representative. 
  

	13.	STANDARD FORMS OF AWARD AGREEMENT. 

 13.1 Award Agreements. Each Award shall comply with and be subject to the terms and conditions set forth in the appropriate form of Award Agreement
approved by the Committee and as amended from time to time. Any Award Agreement may consist of an appropriate form of Notice of Grant and a form of Agreement incorporated therein by reference, or such other form or forms as the Committee may approve
from time to time. 
 13.2 Authority to Vary Terms. The Committee shall have the authority from time to time to vary the terms of any
standard form of Award Agreement either in connection with the grant or amendment of an individual Award or in connection with the authorization of a new standard form or forms; provided, however, that the terms and conditions of any such new,
revised or amended standard form or forms of Award Agreement are not inconsistent with the terms of the Plan. 
  

	14.	CHANGE IN CONTROL. 

 14.1 Effect of Change in Control on Options and SARs. 
 (a) Accelerated Vesting. Notwithstanding any other provision of the Plan to the contrary except as provided in this Section 14.1(a), the Committee, in its sole discretion, may provide in any Award
Agreement or, in the event of a Change in Control, may take such actions as it deems appropriate to provide for the acceleration of the exercisability and vesting in connection with such Change in Control of any or all outstanding Options and SARs
and shares acquired upon the exercise of such Options and SARs upon such conditions and to such extent as the Committee shall determine. Any unexercisable or unvested portion of each outstanding Nonemployee Director Option and any shares acquired
upon the exercise thereof shall be immediately exercisable and vested in full as of the date ten (10) days prior to the date of the Change in Control but conditioned upon the consummation of the Change in Control. 
 (b) Assumption or Substitution. In the event of a Change in Control, the surviving, continuing, successor, or purchasing
entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of any Participant, either assume the Company’s rights and obligations under outstanding Options and SARs or substitute for
outstanding Options and SARs substantially equivalent options and SARs (as the case may be) for the Acquiror’s stock. Any Options or SARs which are not assumed by the Acquiror in connection with the Change in 

  

 31 

 
Control nor exercised as of the time of consummation of the Change in Control shall terminate and cease to be outstanding effective as of the time of
consummation of the Change in Control. 
 (c) Cash-Out of Options. The Committee may, in its sole discretion and
without the consent of any Participant, determine that, upon the occurrence of a Change in Control, each or any Option or SAR outstanding immediately prior to the Change in Control shall be canceled in exchange for a payment with respect to each
vested share of Stock subject to such canceled Option or SAR in (i) cash, (ii) stock of the Company or of a corporation or other business entity a party to the Change in Control, or (iii) other property which, in any such case, shall
be in an amount having a Fair Market Value equal to the excess of the Fair Market Value of the consideration to be paid per share of Stock in the Change in Control over the exercise price per share under such Option or SAR (the
“Spread”). In the event such determination is made by the Committee, the Spread (reduced by applicable withholding taxes, if any) shall be paid to Participants in respect of their canceled Options and SARs as soon as
practicable following the date of the Change in Control. 
 14.2 Effect of Change in Control on Restricted Stock Awards. The Committee
may, in its discretion, provide in any Award Agreement evidencing a Restricted Stock Award that, in the event of a Change in Control, the lapsing of the Restriction Period applicable to the shares subject to the Restricted Stock Award held by a
Participant whose Service has not terminated prior to the Change in Control shall be accelerated effective immediately prior to the consummation of the Change in Control to such extent as specified in such Award Agreement. Any acceleration of the
lapsing of the Restriction Period that was permissible solely by reason of this Section 14.2 and the provisions of such Award Agreement shall be conditioned upon the consummation of the Change in Control. 
 14.3 Effect of Change in Control on Performance Awards. The Committee may, in its discretion, provide in any Award Agreement evidencing a
Performance Award that, in the event of a Change in Control, the Performance Award held by a Participant whose Service has not terminated prior to the Change in Control or whose Service terminated by reason of the Participant’s death or
Disability shall become payable effective as of the date of the Change in Control to such extent as specified in such Award Agreement. 
 14.4 Effect of Change in Control on Restricted Stock Unit Awards. The Committee may, in its discretion, provide in any Award Agreement evidencing a Restricted Stock Unit Award that, in the event of a Change in Control, the Restricted
Stock Unit Award held by a Participant whose Service has not terminated prior to such date shall be settled effective as of the date of the Change in Control to such extent as specified in such Award Agreement. 
 14.5 Effect of Change in Control on Deferred Compensation Awards. The Committee may, in its discretion, provide in any Award Agreement evidencing
a Deferred Compensation Award that, in the event of a Change in Control, the Stock Units pursuant to such Award shall be settled effective as of the date of the Change in Control to such extent as specified in such Award Agreement. 
  

 32 

	15.	COMPLIANCE WITH SECURITIES LAW. 

 The grant of Awards and the issuance of shares of Stock pursuant to any Award shall be subject to compliance with all applicable requirements of federal,
state and foreign law with respect to such securities and the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, no Award may be exercised or shares issued pursuant to an Award unless (a) a
registration statement under the Securities Act shall at the time of such exercise or issuance be in effect with respect to the shares issuable pursuant to the Award or (b) in the opinion of legal counsel to the Company, the shares issuable
pursuant to the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority,
if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite
authority shall not have been obtained. As a condition to issuance of any Stock, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation
and to make any representation or warranty with respect thereto as may be requested by the Company. 
  

	16.	TAX WITHHOLDING. 

 16.1 Tax Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan, or to require the Participant, through payroll withholding, cash payment or otherwise,
including by means of a Cashless Exercise of an Option, to make adequate provision for, the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating Company Group with respect to an Award or the shares
acquired pursuant thereto. The Company shall have no obligation to deliver shares of Stock, to release shares of Stock from an escrow established pursuant to an Award Agreement, or to make any payment in cash under the Plan until the Participating
Company Group’s tax withholding obligations have been satisfied by the Participant. 
 16.2 Withholding in Shares. The Company
shall have the right, but not the obligation, to deduct from the shares of Stock issuable to a Participant upon the exercise or settlement of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair
Market Value, as determined by the Company, equal to all or any part of the tax withholding obligations of the Participating Company Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding
obligations shall not exceed the amount determined by the applicable minimum statutory withholding rates. 
  

	17.	AMENDMENT OR TERMINATION OF PLAN.

 The Committee may amend, suspend or terminate the Plan at any time. However, without the approval of the Company’s
stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except by operation of the provisions of Section 4.4), (b) no change in the class of persons eligible
to receive Incentive Stock Options, (c) no Option and/or SAR repricing as described in Section 3.6, and (d) no other amendment of the Plan that would require approval of the Company’s 

  

 33 

 
stockholders under any applicable law, regulation or rule. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless
expressly provided by the Committee. In any event, no amendment, suspension or termination of the Plan may adversely affect any then outstanding Award without the consent of the Participant unless necessary to comply with any applicable law,
regulation or rule. 
  

	18.	MISCELLANEOUS PROVISIONS. 

 18.1 Repurchase Rights. Shares issued under the Plan may be subject to one or more repurchase options, or other conditions and restrictions as determined by the Committee in its discretion at the time the Award
is granted. The Company shall have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as may be selected by the Company. Upon request by the Company, each
Participant shall execute any agreement evidencing such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates representing shares of Stock acquired hereunder for
the placement on such certificates of appropriate legends evidencing any such transfer restrictions. 
 18.2 Provision of Information.
Each Participant shall be given access to information concerning the Company equivalent to that information generally made available to the Company’s common stockholders. 
 18.3 Rights as Employee, Consultant or Director. No person, even though eligible pursuant to Section 5, shall have a right to be selected as
a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any Award granted under the Plan shall confer on any Participant a right to remain an Employee, Consultant or Director or interfere with or
limit in any way any right of a Participating Company to terminate the Participant’s Service at any time. To the extent that an Employee of a Participating Company other than the Company receives an Award under the Plan, that Award shall in no
event be understood or interpreted to mean that the Company is the Employee’s employer or that the Employee has an employment relationship with the Company. 
 18.4 Rights as a Stockholder. A Participant shall have no rights as a stockholder with respect to any shares covered by an Award until the date of the issuance of such shares (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such shares are issued, except as
provided in Section 4.4 or another provision of the Plan. 
 18.5 Fractional Shares. The Company shall not be required to issue
fractional shares upon the exercise or settlement of any Award. 
 18.6 Severability. If any one or more of the provisions (or any
part thereof) of this Plan shall be held invalid, illegal or unenforceable in any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions (or
any part thereof) of the Plan shall not in any way be affected or impaired thereby. 
  

 34 

 18.7 Beneficiary Designation. Subject to local laws and procedures, each Participant may file with
the Company a written designation of a beneficiary who is to receive any benefit under the Plan to which the Participant is entitled in the event of such Participant’s death before he or she receives any or all of such benefit. Each designation
will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. If a married
Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse. If a Participant dies without an effective designation of a
beneficiary who is living at the time of the Participant’s death, the Company will pay any remaining unpaid benefits to the Participant’s legal representative. 
 18.8 Unfunded Obligation. Participants shall have the status of general unsecured creditors of the Company. Any amounts payable to Participants pursuant to the Plan shall be unfunded and unsecured obligations
for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974. No Participating Company shall be required to segregate any monies from its general funds, or to create any trusts, or establish any
special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations hereunder. Any investments
or the creation or maintenance of any trust or any Participant account shall not create or constitute a trust or fiduciary relationship between the Committee or any Participating Company and a Participant, or otherwise create any vested or
beneficial interest in any Participant or the Participant’s creditors in any assets of any Participating Company. The Participants shall have no claim against any Participating Company for any changes in the value of any assets which may be
invested or reinvested by the Company with respect to the Plan. 
 18.9 Choice of Law. Except to the extent governed by applicable
federal law, the validity, interpretation, construction and performance of the Plan and each Award Agreement shall be governed by the laws of the State of California, without regard to its conflict of law rules.

 PLAN HISTORY AND NOTES TO COMPANY 
  

			
	May 11, 2004	  	Board adopts Plan with a reserve of 16,000,000 shares, reduced at any time by the number of shares subject to the Prior Plan Options, and cumulatively increased (a) on January 1, 2005 and
each subsequent January 1st, through and including January 1, 2013, by a number of shares equal to the smallest of (i) 1.5% of the number of shares of Stock issued and outstanding on the immediately preceding December 31, (ii) 750,000
shares or (iii) an amount determined by the Board.
		
	May 11, 2004	  	Stockholders approve Plan.
		
	IMPORTANT NOTE: At first annual stockholders meeting following close of 3rd calendar year
following the calendar year of IPO (unless plan is materially amended at an earlier date), obtain public company stockholder approval of amendment to plan to add Section 162(m) grant limits and to approve the material terms of the performance
goals as required by Treas. Reg. 1.162-27(e)(4). See Treas. Reg. 1.162-27(f) (private to public company transition rule).	  	See amendment and restatement of the Plan as of  June 14, 2007.

  

			
	IMPORTANT NOTE: Implementation of Section 12—Deferred Compensation Awards or Section 11.6 - deferral of RSU settlement	  	Upon establishment of a Deferred Compensation Award program pursuant to Section 12 or deferral of settlement of RSUs pursuant to Section 11.6, determine whether such program will constitute a
“top-hat” pension plan under ERISA. If so, file notice with Dept. of Labor under ER1SA Reg. 2520.104-23 within 120 days of adoption of resolutions by the Committee to establish the program to obtain exemption from reporting and disclosure
requirements of ERISA. In addition, the program should be reviewed for compliance with Section 409A of the Code.
		
	IMPORTANT NOTE: IRC 162(m) 5 year reapproval of performance goals	  	Because the Committee may change the targets under performance goals, Section 162(m) requires stockholder reapproval of the material terms of performance goals no later than the annual meeting
in the 5th year following the year in which the public company stockholders initially approved such material terms. See Treas. Reg. 1.162-27(e)(4)(vi).
		
	IMPORTANT NOTE: Nasdaq/NYSE evergreen formula plan term limited to 10 years	  	Because the Plan has an evergreen share reserve and share add-back features, the Nasdaq and NYSE stockholder approval rules require that the plan term not exceed 10 years without stockholder
reapproval. See NASD Rule 4350(i)(1)(A) and IM-4320-5; NYSE Listed Company Manual Sec. 303A(8) and FAQs Regarding New Rules on Stockholder Approval for Equity Compensation Plans posted on NYSE website, dated 12/16/2003.

			
		
	June 14, 2007	  	Board adopts an amendment and restatement of the Plan, subject to stockholder approval, to provide (i) a per-person annual limit on the maximum number of shares of Stock subject to Options or
SARs that may be granted to a participant; (ii)a per-person annual limit on the maximum number of shares of Stock subject to awards of Restricted Stock or Restricted Stock Units intended to be Performance-Based Compensation that may be granted to a
participant; (iii) a per-person annual limit on the maximum number of shares of Stock subject to Performance Shares that may be granted to a participant; (iv) an annual dollar limit for each participant with respect to which Performance Units may be
awarded and (v) such other administrative changes with respect to the operation of the Plan.

 COGENT, INC. 
 STOCK OPTION AGREEMENT 
 (Standard Agreement) 
 Cogent, Inc. has granted to the individual (the “Optionee”) named in the Notice of Grant of Stock Option (the
“Notice”) to which this Stock Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase certain shares of Stock upon the terms and conditions
set forth in the Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Cogent, Inc. 2004 Equity Incentive Plan (the “Plan”), as
amended to the Date of Option Grant, the provisions of which are incorporated herein by reference. By signing the Notice, the Optionee: (a) represents that the Optionee has read and is familiar with the terms and conditions of the Notice, the
Plan and this Option Agreement, including the Effect of Termination of Service set forth in Section 7, (b) accepts the Option subject to all of the terms and conditions of the Notice, the Plan and this Option Agreement, (c) agrees to
accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the Notice, the Plan or this Option Agreement, and (d) acknowledges receipt of a copy of the Notice, the Plan and this Option
Agreement. 
  

	1.	DEFINITIONS AND CONSTRUCTION. 

 1.1
Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Notice or the Plan. 
 1.2 Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the
singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise. 
  

	2.	TAX CONSEQUENCES. 

 2.1 Tax Status of
Option. This Option is intended to have the tax status designated in the Notice. 
 (a) Incentive Stock
Option. If the Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The
Optionee should consult with the Optionee’s own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to,
holding period requirements. (NOTE TO OPTIONEE: If the Option is exercised more than three (3) months after the date on which you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in
Section 22(e)(3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an Incentive Stock Option to the extent required by Section 422 of the Code.) 
  

 1 

 (b) Nonstatutory Stock Option. If the Notice so designates, this Option is
intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code. 
 2.2 ISO Fair Market Value Limitation. If the Notice designates this Option as an Incentive Stock Option, then to the extent that the Option (together with all Incentive Stock Options granted to the
Optionee under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any calendar year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000),
the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. For purposes of this Section 2.2, options designated as Incentive Stock Options are taken into account in the order in which they were granted,
and the Fair Market Value of stock is determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation from that set forth in this Section 2.2, such different limitation
shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation
set forth in this Section 2.2, the Optionee may designate which portion of such Option the Optionee is exercising. In the absence of such designation, the Optionee shall be deemed to have exercised the Incentive Stock Option portion of the
Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. (NOTE TO OPTIONEE: If the aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option
Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock option plan of the Participating Company Group) is greater than $100,000, you should contact the Chief
Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.) 
  

	3.	ADMINISTRATION. 

 All questions of
interpretation concerning this Option Agreement shall be determined by the Board. All determinations by the Board shall be final and binding upon all persons having an interest in the Option. Any officer of a Participating Company shall have the
authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the officer has apparent authority with respect to such matter,
right, obligation, or election. 
  

	4.	EXERCISE OF THE OPTION. 

 4.1 Right to
Exercise. Except as otherwise provided herein, the Option shall be exercisable on and after the Date of Option Grant (or if later, the Optionee’s Service commencement date) and prior to the termination of the Option (as provided in
Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option. 
 4.2 Method of Exercise. Exercise of the Option shall be by written notice to the Company which must state the election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other
representations and agreements as 

  

 2 

 
to the Optionee’s investment intent with respect to such shares as may be required pursuant to the provisions of this Option Agreement. The written
notice must be signed by the Optionee and must be delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Company may permit, to the Chief Financial Officer
of the Company, or other authorized representative of the Participating Company Group, prior to the termination of the Option as set forth in Section 6, accompanied by full payment of the aggregate Exercise Price for the number of shares of
Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such written notice and the aggregate Exercise Price. 
 4.3 Payment of Exercise Price. 
 (a) Forms of Consideration Authorized.
Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check, or cash equivalent, (ii) by tender to the Company,
or attestation to the ownership, of whole shares of Stock owned by the Optionee having a Fair Market Value (as determined by the Company without regard to any restrictions on transferability applicable to such stock by reason of federal or state
securities laws or agreements with an underwriter for the Company) not less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as defined in Section 4.3(b), or (iv) by any combination of the foregoing.

 (b) Limitations on Forms of Consideration. 
 (i) Tender of Stock. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company, or attestation to the
ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock. The Option may not be exercised by
tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly, from the Company. 
 (ii) Cashless Exercise. A “Cashless Exercise” means the delivery of a properly executed notice together
with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option
pursuant to a program or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board of Governors of the Federal Reserve System).
The Company reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to decline to approve or terminate any such program or procedure. 
 4.4 Tax Withholding. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, the Optionee
hereby authorizes withholding from payroll and any other amounts payable to the Optionee, and otherwise agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), any sums required to
satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the 

  

 3 

 
Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole
or in part, of any shares acquired upon exercise of the Option, (iii) the operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired upon exercise
of the Option. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Participating Company Group have been satisfied by the Optionee. 
 4.5 Certificate Registration. Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the shares as to
which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the names of the heirs of the Optionee. 
 4.6 Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares of Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state
or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or
the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the
Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an
applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE
OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and
sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the
Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect thereto as may be
requested by the Company. 
 4.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of
the Option. 
  

	5.	TRANSFERABILITY OF THE OPTION. 

 The Option
may generally only be exercised during the lifetime of the Optionee only by the Optionee or the Optionee’s guardian or legal representative and may not be exercised, assigned or transferred in any manner except by will, by the laws of descent
and distribution, or as otherwise provided in the Plan. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person 

  

 4 

 
empowered to do so under the deceased Optionee’s will or under the then applicable laws of descent and distribution. 
  

	6.	TERMINATION OF THE OPTION. 

 The Option shall
terminate and may no longer be exercised on the first to occur of (a) the Option Expiration Date, (b) the last date for exercising the Option following termination of the Optionee’s Service as described in Section 7, or
(c) a Change in Control to the extent provided in Section 8. 
  

	7.	EFFECT OF TERMINATION OF SERVICE. 

 7.1
Option Exercisability. 
 (a) Disability. If the Optionee’s Service with the Participating Company
Group terminates because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal
representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 
 (b) Death. If the Optionee’s Service with the Participating Company Group terminates because of the death of the
Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to exercise the Option
by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. The Optionee’s
Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee’s termination of Service. 
 (c) Other Termination of Service. If the Optionee’s Service with the Participating Company Group terminates for any
reason, except Disability or death, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee’s Service terminated, may be exercised by the Optionee at any time prior to the expiration of three
(3) months (or such other longer period of time as determined by the Board, in its discretion) after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 
 7.2 Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of the Option within the applicable time periods set
forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until three (3) months after the date the Optionee is notified by the Company that the Option is exercisable, but in any event no
later than the Option Expiration Date. 
 7.3 Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a
sale within the applicable time periods set forth in Section 7.1 of shares acquired upon the exercise of the Option would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the
earliest to occur of (i) the tenth (10th) day 

  

 5 

 
following the date on which a sale of such shares by the Optionee would no longer be subject to such suit, (ii) the one hundred and ninetieth
(190th) day after the Optionee’s termination of Service, or (iii) the Option Expiration Date. 
 7.4 Certain
Definitions. 
 (a) “Termination After Change in Control” shall mean either of the following
events occurring within twenty-four (24) months after a Change in Control: 
 (i) termination by the Participating
Company Group of the Optionee’s Service with the Participating Company Group for any reason other than for Cause (as defined in 7.4(b) below); or 
 (ii) the Optionee’s resignation for Good Reason (as defined in 7.4(c) below) from all capacities in which the Optionee is then rendering Service to the Participating Company Group within a reasonable period of
time following the event constituting Good Reason. 
 Notwithstanding any provision herein to the contrary, Termination After Change in Control shall not
include any termination of the Optionee’s Service with the Participating Company Group which (1) is for Cause (as defined below); (2) is a result of the Optionee’s death or disability; (3) is a result of the Optionee’s
voluntary termination of Service other than for Good Reason; or (4) occurs prior to the effectiveness of a Change in Control. 
 (b) “Cause” shall mean any of the following: (i) the Optionee’s theft, dishonesty, or falsification of any Participating Company documents or records; (ii) the Optionee’s improper use or
disclosure of a Participating Company’s confidential or proprietary information; (iii) any action by the Optionee which has a detrimental effect on a Participating Company’s reputation or business; (iv) the Optionee’s
failure or inability to perform adequately any reasonable assigned duties as determined by a Participating Company; (v) any violation by the Optionee of any material agreement between the Optionee and a Participating Company, which breach is
not cured pursuant to the terms of such agreement or any breach of any material statutory duty to a Participating Company; or (vi) the Optionee’s conviction (including any plea of guilty or nolo contendere) of any felony or crime involving
moral turpitude or dishonesty. 
 (c) “Good Reason” shall mean any one or more of the following:

 (i) without the Optionee’s express written consent, the relocating of the principal place of the Optionee’s
Service to a location that is more than fifty (50) miles from the Optionee’s principal place of Service immediately prior to the date of the Change in Control; 
 (ii) any failure by the Participating Company Group to pay, or any reduction by the Participating Company Group of the Optionee’s
base salary in effect immediately prior to the date of the Change in Control; or 
 (iii) any failure by the Participating
Company Group to pay, or (1) continue to provide to the Optionee a package of walefare benefit plans, including, but not profit sharing and retirement plans, that, taken as a whole, provide substantially similar benefits 

  

 6 

 
to those to which the Optionee was entitled immediately prior to to the Change in Control (except that the Optionee’s contributions may be increased to
the extent of any cost increases imposed by third parties) or (2) provide the Optionee with all other fringe benefits (or their equivalent) from time to time in effect for the benefit of any employee of the Participating Company Group.

  

	8.	CHANGE IN CONTROL. 

 In the event of a Change
in Control, the Acquiring Corporation may either assume the Company’s rights and obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation’s stock. In the event that the
Acquiring Corporation elects not to assume or substitute for outstanding Options in connection with a Change in Control, the exercisability and vesting of each such outstanding Option held by the Optionee, provided the Optionee’s Service has
not terminated prior to such date shall be 100% accelerated, effective as of the date ten (10) days prior to the date of the Change in Control. The Option shall terminate and cease to be outstanding effective as of the date of the Change in
Control to the extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control. Notwithstanding the foregoing, shares acquired
upon exercise of the Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as
otherwise provided herein. 
  

	9.	ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. 

 In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise
Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an
Ownership Change Event) shares of another corporation (the “New Shares”), the Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option Shares
and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be rounded
down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. The adjustments determined by the Board pursuant to this Section 9 shall be
final, binding and conclusive. 
  

	10.	RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT. 

 The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, 

  

 7 

 
except as provided in Section 9. If the Optionee is an Employee, the Optionee understands and acknowledges that, except as otherwise provided in a
separate, written employment agreement between a Participating Company and the Optionee, the Optionee’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Optionee any right to
continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company Group to terminate the Optionee’s Service as an Employee or Consultant, as the case may be, at any time. 
  

	11.	NOTICE OF SALES UPON DISQUALIFYING DISPOSITION. 

 The Optionee shall dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In addition, if the Notice designates this Option as an Incentive Stock Option, the Optionee shall
(a) promptly notify the Chief Financial Officer of the Company if the Optionee disposes of any of the shares acquired pursuant to the Option within one (1) year after the date the Optionee exercises all or part of the Option or within two
(2) years after the Date of Option Grant and (b) provide the Company with a description of the circumstances of such disposition. Until such time as the Optionee disposes of such shares in a manner consistent with the provisions of this
Option Agreement, unless otherwise expressly authorized by the Company, the Optionee shall hold all shares acquired pursuant to the Option in the Optionee’s name (and not in the name of any nominee) for the one-year period immediately after the
exercise of the Option and the two-year period immediately after Date of Option Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing shares acquired pursuant to
the Option requesting the transfer agent for the Company’s stock to notify the Company of any such transfers. The obligation of the Optionee to notify the Company of any such transfer shall continue notwithstanding that a legend has been placed
on the certificate pursuant to the preceding sentence. 
  

	12.	LEGENDS. 

 The Company may at any time place
legends referencing any applicable federal, state or foreign securities law restrictions, and, if applicable, that the shares were acquired upon exercise of an Incentive Stock Option on all certificates representing shares of stock subject to the
provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry
out the provisions of this Section. 
  

	13.	LOCK-UP AGREEMENT. 

 The Optionee hereby
agrees that in the event of any underwritten public offering of stock, including an initial public offering of stock, made by the Company pursuant to an effective registration statement filed under the Securities Act, the Optionee shall not offer,
sell, contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the
effective date of such registration statement as may be established by the underwriter for such public offering; provided, however, that such period of 

  

 8 

 
time shall not exceed one hundred eighty (180) days from the effective date of the registration statement to be filed in connection with such public
offering. The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act. 
  

	14.	RESTRICTIONS ON TRANSFER OF SHARES. 

 No
shares acquired upon exercise of the Option may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Optionee), assigned, pledged, hypothecated or otherwise disposed of, including by operation of
law, in any manner which violates any of the provisions of this Option Agreement, and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books any shares which will have been transferred in
violation of any of the provisions set forth in this Option Agreement or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares will have been so transferred.

  

	15.	MISCELLANEOUS PROVISIONS. 

 15.1 Binding

 COGENT, INC. 
 STOCK OPTION AGREEMENT 
 (Double Trigger Acceleration) 
 Cogent, Inc. has granted to the individual (the “Optionee”) named in the Notice of Grant of Stock Option (the
“Notice”) to which this Stock Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase certain shares of Stock upon the terms and conditions
set forth in the Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Cogent, Inc. 2004 Equity Incentive Plan (the “Plan”), as
amended to the Date of Option Grant, the provisions of which are incorporated herein by reference. By signing the Notice, the Optionee: (a) represents that the Optionee has read and is familiar with the terms and conditions of the Notice, the
Plan and this Option Agreement, including the Effect of Termination of Service set forth in Section 7, (b) accepts the Option subject to all of the terms and conditions of the Notice, the Plan and this Option Agreement, (c) agrees to
accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the Notice, the Plan or this Option Agreement, and (d) acknowledges receipt of a copy of the Notice, the Plan and this Option
Agreement. 
  

	1.	DEFINITIONS AND CONSTRUCTION. 

 1.1 Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Notice or the Plan. 
 1.2 Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation
of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the
context clearly requires otherwise. 
  

	2.	TAX CONSEQUENCES. 

 2.1 Tax Status of
Option. This Option is intended to have the tax status designated in the Notice. 
 (a) Incentive Stock
Option. If the Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The
Optionee should consult with the Optionee’s own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to,
holding period requirements. (NOTE TO OPTIONEE: If the Option is exercised more than three (3) months after the date on which you cease to be an Employee (other than by reason of your death or permanent and total disability as defined in
Section 22(e)(3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an Incentive Stock Option to the extent required by Section 422 of the Code.) 
  

 13 

 (b) Nonstatutory Stock Option. If the Notice so designates, this Option is
intended to be a Nonstatutory Stock Option and shall not be treated as an Incentive Stock Option within the meaning of Section 422(b) of the Code. 
 2.2 ISO Fair Market Value Limitation. If the Notice designates this Option as an Incentive Stock Option, then to the extent that the Option (together with all Incentive Stock Options granted to the
Optionee under all stock option plans of the Participating Company Group, including the Plan) becomes exercisable for the first time during any calendar year for shares having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000),
the portion of such options which exceeds such amount will be treated as Nonstatutory Stock Options. For purposes of this Section 2.2, options designated as Incentive Stock Options are taken into account in the order in which they were granted,
and the Fair Market Value of stock is determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation from that set forth in this Section 2.2, such different limitation
shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation
set forth in this Section 2.2, the Optionee may designate which portion of such Option the Optionee is exercising. In the absence of such designation, the Optionee shall be deemed to have exercised the Incentive Stock Option portion of the
Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. (NOTE TO OPTIONEE: If the aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option
Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or any other stock option plan of the Participating Company Group) is greater than $100,000, you should contact the Chief
Financial Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.) 
  

	3.	ADMINISTRATION. 

 All questions of
interpretation concerning this Option Agreement shall be determined by the Board. All determinations by the Board shall be final and binding upon all persons having an interest in the Option. Any officer of a Participating Company shall have the
authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the officer has apparent authority with respect to such matter,
right, obligation, or election. 
  

	4.	EXERCISE OF THE OPTION. 

 4.1 Right to
Exercise. Except as otherwise provided herein, the Option shall be exercisable on and after the Date of Option Grant (or if later, the Optionee’s Service commencement date) and prior to the termination of the Option (as provided in
Section 6) in an amount not to exceed the number of Vested Shares less the number of shares previously acquired upon exercise of the Option. 
  

 14 

 4.2 Method of Exercise. Exercise of the Option shall be by written notice to the Company which
must state the election to exercise the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements as to the Optionee’s investment intent with respect to such shares as may
be required pursuant to the provisions of this Option Agreement. The written notice must be signed by the Optionee and must be delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by
such other means as the Company may permit, to the Chief Financial Officer of the Company, or other authorized representative of the Participating Company Group, prior to the termination of the Option as set forth in Section 6, accompanied by
full payment of the aggregate Exercise Price for the number of shares of Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such written notice and the aggregate Exercise Price. 
 4.3 Payment of Exercise Price. 
 (a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise Price for the number of shares of Stock for which the Option is being exercised shall be made
(i) in cash, by check, or cash equivalent, (ii) by tender to the Company, or attestation to the ownership, of whole shares of Stock owned by the Optionee having a Fair Market Value (as determined by the Company without regard to any
restrictions on transferability applicable to such stock by reason of federal or state securities laws or agreements with an underwriter for the Company) not less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as
defined in Section 4.3(b), or (iv) by any combination of the foregoing. 
 (b) Limitations on Forms of
Consideration. 
 (i) Tender of Stock. Notwithstanding the foregoing, the Option may not be exercised by tender
to the Company, or attestation to the ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.
The Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the Optionee for more than six (6) months or were not acquired, directly or indirectly,
from the Company. 
 (ii) Cashless Exercise. A “Cashless Exercise” means the delivery of a
properly executed notice together with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares of Stock acquired
upon the exercise of the Option pursuant to a program or procedure approved by the Company (including, without limitation, through an exercise complying with the provisions of Regulation T as promulgated from time to time by the Board 

  

 15 

 
of Governors of the Federal Reserve System). The Company reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to
decline to approve or terminate any such program or procedure. 
 4.4 Tax Withholding. At the time the Option is exercised, in whole
or in part, or at any time thereafter as requested by the Company, the Optionee hereby authorizes withholding from payroll and any other amounts payable to the Optionee, and otherwise agrees to make adequate provision for (including by means of a
Cashless Exercise to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any, which arise in connection with the Option,
including, without limitation, obligations arising upon (i) the exercise, in whole or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option, (iii) the operation of any law
or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect to any shares acquired upon exercise of the Option. The Company shall have no obligation to deliver shares of Stock until the tax
withholding obligations of the Participating Company Group have been satisfied by the Optionee. 
 4.5 Certificate Registration.
Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the shares as to which the Option is exercised shall be registered in the name of the Optionee, or, if applicable, in the names of the heirs of the
Optionee. 
 4.6 Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares of
Stock upon exercise of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. The Option may not be exercised if the issuance of shares of Stock upon exercise
would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system upon which the Stock may then be listed. In addition, the Option may not
be exercised unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to
the Company, the shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. THE OPTIONEE IS CAUTIONED THAT THE OPTION MAY NOT BE
EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having
jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell
such shares as to which such requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require the Optionee to satisfy any qualifications that may be necessary or appropriate, to evidence
compliance 

  

 16 

 
with any applicable law or regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 
 4.7 Fractional Shares. The Company shall not be required to issue fractional shares upon the exercise of the Option. 
  

	5.	TRANSFERABILITY OF THE OPTION. 

 The Option
may generally only be exercised during the lifetime of the Optionee only by the Optionee or the Optionee’s guardian or legal representative and may not be exercised, assigned or transferred in any manner except by will, by the laws of descent
and distribution, or as otherwise provided in the Plan. Following the death of the Optionee, the Option, to the extent provided in Section 7, may be exercised by the Optionee’s legal representative or by any person empowered to do so under
the deceased Optionee’s will or under the then applicable laws of descent and distribution. 
  

	6.	TERMINATION OF THE OPTION. 

 The Option shall
terminate and may no longer be exercised on the first to occur of (a) the Option Expiration Date, (b) the last date for exercising the Option following termination of the Optionee’s Service as described in Section 7, or
(c) a Change in Control to the extent provided in Section 8. 
  

	7.	EFFECT OF TERMINATION OF SERVICE. 

 7.1
Option Exercisability. 
 (a) Disability. If the Optionee’s Service with the Participating Company
Group terminates because of the Disability of the Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee (or the Optionee’s guardian or legal
representative) at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. 
 (b) Death. If the Optionee’s Service with the Participating Company Group terminates because of the death of the
Optionee, the Option, to the extent unexercised and exercisable on the date on which the Optionee’s Service terminated, may be exercised by the Optionee’s legal representative or other person who acquired the right to exercise the Option
by reason of the Optionee’s death at any time prior to the expiration of twelve (12) months after the date on which the Optionee’s Service terminated, but in any event no later than the Option Expiration Date. The Optionee’s
Service shall be deemed to have terminated on account of death if the Optionee dies within three (3) months after the Optionee’s termination of Service. 
 (c) Other Termination of Service. If the Optionee’s Service with the Participating Company Group terminates for any
reason, except Disability, death 

  

 17 

 
or Termination After Change in Control, the Option, to the extent unexercised and exercisable by the Optionee on the date on which the Optionee’s
Service terminated, may be exercised by the Optionee at any time prior to the expiration of three (3) months (or such other longer period of time as determined by the Board, in its discretion) after the date on which the Optionee’s Service
terminated, but in any event no later than the Option Expiration Date. 
 7.2 Extension if Exercise Prevented by Law. Notwithstanding
the foregoing, if the exercise of the Option within the applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until three (3) months after the date the
Optionee is notified by the Company that the Option is exercisable, but in any event no later than the Option Expiration Date. 
 7.3
Extension if Optionee Subject to Section 16(b). Notwithstanding the foregoing, if a sale within the applicable time periods set forth in Section 7.1 of shares acquired upon the exercise of the Option would subject the Optionee to
suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Optionee would no longer be subject to
such suit, (ii) the one hundred and ninetieth (190th) day after the Optionee’s termination of Service, or (iii) the Option Expiration Date. 
  

	8.	CHANGE IN CONTROL. 

 In the event of a Change
in Control, the Acquiring Corporation may either assume the Company’s rights and obligations under the Option or substitute for the Option a substantially equivalent option for the Acquiring Corporation’s stock. In the event that the
Acquiring Corporation elects not to assume or substitute for outstanding Options in connection with a Change in Control, the exercisability and vesting of each such outstanding Option held by the Optionee, provided the Optionee’s Service has
not terminated prior to such date shall be 100% accelerated, effective as of the date ten (10) days prior to the date of the Change in Control. The Option shall terminate and cease to be outstanding effective as of the date of the Change in
Control to the extent that the Option is neither assumed or substituted for by the Acquiring Corporation in connection with the Change in Control nor exercised as of the date of the Change in Control. Notwithstanding the foregoing, shares acquired
upon exercise of the Option prior to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall continue to be subject to all applicable provisions of this Option Agreement except as
otherwise provided herein. 
  

	9.	ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. 

 In the event of any stock dividend, stock split, reverse stock split, recapitalization, combination, reclassification, or similar change in the capital structure of the Company, appropriate adjustments shall be made in the number, Exercise
Price and class of shares of stock subject to the Option. If a majority of the shares which are of the same class as the shares that are subject to the Option are exchanged for, converted into, or otherwise become (whether or not pursuant to an
Ownership Change Event) shares of another corporation (the “New Shares”), the 

  

 18 

 
Board may unilaterally amend the Option to provide that the Option is exercisable for New Shares. In the event of any such amendment, the Number of Option
Shares and the Exercise Price shall be adjusted in a fair and equitable manner, as determined by the Board, in its discretion. Notwithstanding the foregoing, any fractional share resulting from an adjustment pursuant to this Section 9 shall be
rounded down to the nearest whole number, and in no event may the Exercise Price be decreased to an amount less than the par value, if any, of the stock subject to the Option. The adjustments determined by the Board pursuant to this Section 9
shall be final, binding and conclusive. 
  

	10.	RIGHTS AS A STOCKHOLDER, EMPLOYEE OR CONSULTANT. 

 The Optionee shall have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate for the shares for which the Option has been exercised (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as
provided in Section 9. If the Optionee is an Employee, the Optionee understands and acknowledges that, except as otherwise provided in a separate, written employment agreement between a Participating Company and the Optionee, the
Optionee’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Optionee any right to continue in the Service of a Participating Company or interfere in any way with any right of
the Participating Company Group to terminate the Optionee’s Service as an Employee or Consultant, as the case may be, at any time. 
  

	11.	NOTICE OF SALES UPON DISQUALIFYING DISPOSITION. 

 The Optionee shall dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In addition, if the Notice designates this Option as an Incentive Stock Option, the Optionee
shall (a) promptly notify the Chief Financial Officer of the Company if the Optionee disposes of any of the shares acquired pursuant to the Option within one (1) year after the date the Optionee exercises all or part of the Option or
within two (2) years after the Date of Option Grant and (b) provide the Company with a description of the circumstances of such disposition. Until such time as the Optionee disposes of such shares in a manner consistent with the provisions
of this Option Agreement, unless otherwise expressly authorized by the Company, the Optionee shall hold all shares acquired pursuant to the Option in the Optionee’s name (and not in the name of any nominee) for the one-year period immediately
after the exercise of the Option and the two-year period immediately after Date of Option Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing shares acquired
pursuant to the Option requesting the transfer agent for the Company’s stock to notify the Company of any such transfers. The obligation of the Optionee to notify the Company of any such transfer shall continue notwithstanding that a legend has
been placed on the certificate pursuant to the preceding sentence. 
  

 19 

	12.	LEGENDS. 

 The Company may at any time place
legends referencing any applicable federal, state or foreign securities law restrictions, and, if applicable, that the shares were acquired upon exercise of an Incentive Stock Option on all certificates representing shares of stock subject to the
provisions of this Option Agreement. The Optionee shall, at the request of the Company, promptly present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Optionee in order to carry
out the provisions of this Section. 
  

	13.	LOCK-UP AGREEMENT. 

 The Optionee hereby
agrees that in the event of any underwritten public offering of stock, including an initial public offering of stock, made by the Company pursuant to an effective registration statement filed under the Securities Act, the Optionee shall not offer,
sell, contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any shares of stock of the Company or any rights to acquire stock of the Company for such period of time from and after the
effective date of such registration statement as may be established by the underwriter for such public offering; provided, however, that such period of time shall not exceed one hundred eighty (180) days from the effective date of the
registration statement to be filed in connection with such public offering. The foregoing limitation shall not apply to shares registered in the public offering under the Securities Act. 
  

	14.	RESTRICTIONS ON TRANSFER OF SHARES. 

 No
shares acquired upon exercise of the Option may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of the Optionee), assigned, pledged, hypothecated or otherwise disposed of, including by operation of
law, in any manner which violates any of the provisions of this Option Agreement, and any such attempted disposition shall be void. The Company shall not be required (a) to transfer on its books any shares which will have been transferred in
violation of any of the provisions set forth in this Option Agreement or (b) to treat as owner of such shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such shares will have been so transferred.

  

	15.	MISCELLANEOUS PROVISIONS. 

 15.1 Binding
Effect. Subject to the restrictions on transfer set forth herein, this Option Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns.

 15.2 Termination or Amendment. The Board may terminate or amend the Plan or the Option at any time; provided, however, that except
as provided in Section 8 in connection with a Change in Control, no such termination or amendment may adversely affect the Option or any unexercised portion hereof without the consent of the Optionee unless such termination or amendment is
necessary to comply with any applicable law or government regulation or is required to enable the Option, if designated an Incentive Stock Option in the Notice, to qualify as an Incentive Stock Option. No amendment or addition to this Option
Agreement shall be effective unless in writing. 
  

 20 

 15.3 Notices. Any notice required or permitted hereunder shall be given in writing and shall be
deemed effectively given (except to the extent that this Option Agreement provides for effectiveness only upon actual receipt of such notice) upon personal delivery or upon deposit in the United States Post Office, by registered or certified mail,
with postage and fees prepaid, addressed to the other party at the address shown below that party’s signature on the Notice or at such other address as such party may designate in writing from time to time to the other party. 
 15.4 Integrated Agreement. The Notice, this Option Agreement and the Plan constitute the entire understanding and agreement of the Optionee and
the Participating Company Group with respect to the subject matter contained herein or therein and supersedes any prior agreements, understandings, restrictions, representations, or warranties among the Optionee and the Participating Company Group
with respect to such subject matter other than those as set forth or provided for herein or therein. To the extent contemplated herein or therein, the provisions of the Notice and the Option Agreement shall survive any exercise of the Option and
shall remain in full force and effect. 
 15.5 Applicable Law. This Option Agreement shall be governed by the laws of the State of
California as such laws are applied to agreements between California residents entered into and to be performed entirely within the State of California. 
 15.6 Counterparts. The Notice may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
