as it may consider necessary or appropriate for such purposes without thereby affecting the terms of the Plan as in effect for any other purpose; provided, however, that no such supplements, amendments, restatements, or alternative versions
shall increase the share limitations contained in Section 3.1 of the Plan.

 (c) PAYMENT. The Committee shall determine the methods by which the exercise price of an Option may be paid, the form of payment, including, without limitation, cash, promissory note bearing interest at no less than
such rate as shall then preclude the imputation of interest under the Code, shares of Stock held for longer than six months having a Fair Market Value on the date of delivery equal to the aggregate exercise price of the Option or exercised portion

 6 








 
delivery of a notice that the Participant has placed a market sell order with a broker with respect to shares of Stock then issuable upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in satisfaction of the Option exercise price, provided that payment of such proceeds is then made to the Company upon
settlement of such sale), and the methods by which shares of Stock shall be delivered or deemed to be delivered to Participants. Notwithstanding any other provision of the Plan to the contrary, no Participant who is a member of the Board or an
“executive officer” of the Company within the meaning of Section 13(k) of the Exchange Act shall be permitted to pay the exercise price of an Option in any method which would violate Section 13(k).

forfeiture conditions relating to Restricted Stock.

 ARTICLE 7 
 STOCK APPRECIATION RIGHTS 
 7.1 GRANT OF STOCK APPRECIATION RIGHTS. A Stock
Appreciation Right may be granted to any Eligible Participant selected by the Committee. A Stock Appreciation Right may be granted (a) in connection and simultaneously with the grant of an Option, (b) with respect to a previously granted
Option, or (c) independent of an Option. A Stock Appreciation Right shall be subject to such terms and conditions not inconsistent with the Plan as the Committee shall impose and shall be evidenced by an Award Agreement. 
 7.2 COUPLED STOCK APPRECIATION RIGHTS. 
 (a) A Coupled Stock Appreciation Right (“CSAR”) shall be related to a particular Option and shall be exercisable only when and to the extent the related Option is exercisable. 
 (b) A CSAR may be granted to a Participant for no more than the number of shares subject to the simultaneously or previously granted Option to which it
is coupled. 
 (c) A CSAR shall entitle the Participant (or other person entitled to exercise the Option pursuant to the Plan) to surrender
to the Company unexercised a portion of the Option to which the CSAR relates (to the extent then exercisable pursuant to its terms) and to receive from the Company in exchange therefor an amount determined by multiplying the difference obtained by
subtracting the Option exercise price from the Fair Market Value of a share of Stock on the date of exercise of the CSAR by the number of shares of Stock with respect to which the CSAR shall have been exercised, subject to any limitations the
Committee may impose. 
 7.3 INDEPENDENT STOCK APPRECIATION RIGHTS. 
 (a) An Independent Stock Appreciation Right (“ISAR”) shall be unrelated to any Option and shall have a term set by the Committee. An ISAR
shall be exercisable in such installments as the Committee may determine. An ISAR shall cover such number of shares of Stock as the Committee may determine. The exercise price per share of Stock subject to each ISAR shall be set by the Committee;
provided, however, that, the Committee in its sole and absolute discretion may provide that the ISAR may be exercised subsequent to a termination of employment or service, as applicable, or following a Change of Control, or because of the
Participant’s retirement, death or Disability, or otherwise. 
 (b) An ISAR shall entitle the Participant (or other person entitled to
exercise the ISAR pursuant to the Plan) to exercise all or a specified portion of the ISAR (to the extent then exercisable pursuant to its terms) and to receive from the Company an amount determined by multiplying the difference obtained by
subtracting the exercise price per share of the ISAR from the Fair Market Value of a share of Stock on the date of exercise of the ISAR by the number of shares of Stock with respect to which the ISAR shall have been exercised, subject to any
limitations the Committee may impose. 
 7.4 PAYMENT AND LIMITATIONS ON EXERCISE. 
 (a) Payment of the amounts determined under Section 7.2(c) and 7.3(b) above shall be in cash, in Stock (based on its Fair Market Value as of the date

 8 








 (b) To the extent any payment under Section 7.2(c) or 7.3(b) is effected in Stock it shall be made
subject to satisfaction of all provisions of Article 5 above pertaining to Options. 
 ARTICLE 8 
 OTHER TYPES OF AWARDS 
 8.1
PERFORMANCE SHARE AWARDS. Any Eligible Participant selected by the Committee may be granted one or more Performance Share awards which may be denominated in a number of shares of Stock or in a dollar value of shares of Stock and which
may be linked to any one or more specific performance criteria determined appropriate by the Committee, in each case on a specified date or dates or over any period or periods determined by the Committee. In making such determinations, the Committee
shall consider (among such other factors as it deems relevant in light of the specific type of award) the contributions, responsibilities and other compensation of the particular Participant. 
 8.2 DIVIDEND EQUIVALENTS. 
 (a)
Any Eligible Participant selected by the Committee may be granted Dividend Equivalents based on the dividends declared on the shares of Stock that are subject to any Award, to be credited as of dividend payment dates, during the period between the
date the Award is granted and the date the Award is exercised, vests or expires, as determined by the Committee. Such Dividend Equivalents shall be converted to cash or additional shares of Stock by such formula and at such time and subject to such
limitations as may be determined by the Committee. 
 8.3 STOCK PAYMENTS. Any Eligible Participant selected by the Committee

the Committee may be granted an award of Deferred Stock in the manner determined from time to time by the Committee. The number of shares of Deferred Stock shall be determined by the Committee and may be linked to specific performance criteria
determined to be appropriate by the Committee, in each case on a specified date or dates or over any period or periods determined by the Committee. Stock underlying a Deferred Stock award will not be issued until the Deferred Stock award has vested,
pursuant to a vesting schedule or performance criteria set by the Committee. Unless otherwise provided by the Committee, a Participant awarded Deferred Stock shall have no rights as a Company stockholder with respect to such Deferred Stock until
such time as the Deferred Stock Award has vested and the Stock underlying the Deferred Stock Award has been issued. 
 8.5

 9

of any Award of Performance Shares, Deferred Stock or Stock Payments; provided, however, that such price shall not be less than the par value of a share of Stock, unless otherwise permitted by applicable state law. 
 8.7 EXERCISE UPON TERMINATION OF EMPLOYMENT OR SERVICE. An Award of Performance Shares, Dividend Equivalents, Deferred Stock and Stock
Payments shall only be exercisable or payable while the Participant is an Employee of the Company; provided, however, that the Committee in its sole and absolute discretion may provide that an Award of Performance Shares, Dividend Equivalents, Stock
Payments or Deferred Stock may be exercised or paid subsequent to a termination of employment or service, as applicable, or following a Change of Control, or because of the Participant’s retirement, death or Disability, or otherwise.

 ARTICLE 9

 PROVISIONS APPLICABLE TO AWARDS 
 9.1 STAND-ALONE AND TANDEM AWARDS. Awards granted pursuant to the Plan may, in the discretion of the Committee, be granted either alone, in addition to, or in tandem with, any other Award granted
pursuant to the Plan. Awards granted in addition to or in tandem with other Awards may be granted either at the same time as or at a different time from the grant of such other Awards. 
 9.2 AWARD AGREEMENT. Awards under the Plan shall be evidenced by Award Agreements that set forth the terms, conditions and limitations for
each Award which may include the term of an Award, the provisions applicable in the event the Participant’s employment or service terminates, and the Company’s authority to unilaterally or bilaterally amend, modify, suspend, cancel or
rescind an Award. 
 9.3 LIMITS ON TRANSFER. No right or interest of a Participant in any Award may be pledged, encumbered, or
hypothecated to or in favor of any party other than the Company or a Subsidiary, or shall be subject to any lien, obligation, or liability of such Participant to any other party other than the Company or a Subsidiary. No Award shall be assigned,
transferred, or otherwise disposed of by a Participant other than by will or the laws of descent and distribution. 
 9.4
BENEFICIARIES. Notwithstanding Section 9.3, a Participant may, in the 

  

 10 








 
manner determined by the Committee, designate a beneficiary to exercise the rights of the Participant and to receive any distribution with respect to any
Award upon the Participant’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights pursuant to the Plan is subject to all terms and conditions of the Plan and any Award Agreement applicable to the
Participant, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Committee. If the Participant is married and resides in a community property state, a
designation of a person other than the Participant’s spouse as his beneficiary with respect to more than 50% of the Participant’s interest in the Award shall not be effective without the prior written consent of the Participant’s
spouse. If no beneficiary has been designated or survives the Participant, payment shall be made to the person entitled thereto pursuant to the Participant’s will or the laws of descent and distribution. Subject to the foregoing, a beneficiary
designation may be changed or revoked by a Participant at any time provided the change or revocation is filed with the Committee. 
 9.5
STOCK CERTIFICATES. Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Award, unless and until the Board
has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares
of Stock are listed or traded. All Stock certificates delivered pursuant to the Plan are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal, state, or foreign jurisdiction,
securities or other laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate to reference
restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Board may require that a Participant make such reasonable covenants, agreements, and representations as the Board, in its discretion, deems advisable
in order to comply with any such laws, regulations, or requirements. The Committee shall have the right to require any Participant to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a
window-period limitation, as may be imposed in the discretion of the Committee. 
 ARTICLE 10 
 CHANGES IN CAPITAL STRUCTURE 
 10.1
ADJUSTMENTS. 
 (a) EQUITY RESTRUCTURING. In connection with the occurrence of any Equity Restructuring, and notwithstanding
anything to the contrary in Section 10.1(b): 
 (1) The number and type of securities subject to each outstanding Award and the exercise
price or grant price per share thereof, as well as any other applicable terms and conditions of each outstanding Award (including, without limitation, any performance targets or criteria with respect thereto), will be proportionately adjusted. The
adjustments provided under this Section 10.1(a)(1) shall be nondiscretionary and shall be final and binding on the affected Participant and the Company. 
  

 11 








 (2) The Committee shall make such proportionate adjustments, if any, as the Committee in its discretion
may deem appropriate to reflect such Equity Restructuring with respect to the aggregate number and kind of shares that may be issued under the Plan (including, but not limited to, adjustments of the limitation in Section 3.1). 
 (b) OTHER CHANGES IN CAPITAL STRUCTURE. In the event that the Committee determines that other than an Equity Restructuring, any dividend or other
distribution (whether in the form of cash, Stock, other securities or other property), reorganization, merger, consolidation, combination, repurchase, liquidation, dissolution, or sale transfer, exchange or other disposition of all or substantially
all of the assets of the Company, or exchange of Stock or other securities of the Company, issuance or warrants or other rights to purchase Stock or other securities of the Company or other similar corporate transaction or event, in the
Committee’s sole discretion, affects the Stock such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the
Plan or with respect to an Award, then the Committee shall, in such manner as it may deem equitable, adjust any or all of: 
 (1) The number
and kind of shares of Stock (or other securities or property) with respect to which Awards may be granted or awarded (including, but not limited to, adjustments of the limitation in Section 3.1 on the maximum number and kind of shares which may
be issued); 
 (2) The number and kind of shares of Stock (or other securities or property) subject to outstanding Awards; and 

(3) The grant or exercise price per share with respect to any outstanding Award, as well as any other applicable terms and conditions of each
outstanding Award (including, without limitation, any performance targets or criteria with respect thereto). 
 10.2 ACCELERATION UPON
A CHANGE OF CONTROL. If a Change of Control occurs and a Participant’s Awards are not converted, assumed, or replaced by a successor, such Awards shall become fully exercisable and all forfeiture restrictions on such Awards shall lapse.
Upon, or in anticipation of, a Change of Control, the Committee may cause any and all Awards outstanding hereunder to terminate at a specific time in the future and shall give each Participant the right to exercise such Awards during a period of
time as the Committee, in its sole and absolute discretion, shall determine. In the event that the terms of any agreement between the Company or any Subsidiary or affiliate and a Participant contains provisions that conflict with and are more
restrictive than the provisions of this Section 10.2, this Section 10.2 shall prevail and control and the more restrictive terms of such agreement (and only such terms) shall be of no force or effect. 
 10.3 OUTSTANDING AWARDS – CERTAIN MERGERS. Subject to any required action by the stockholders of the Company, in the event that the
Company shall be the surviving corporation in any merger or consolidation (except a merger or consolidation as a result of which the holders of shares of Stock receive securities of another corporation), each Award outstanding on the date of such
merger or consolidation shall pertain to and apply to the securities that a holder of the number of shares of Stock subject to such Award would have received in such merger or consolidation. 
  

 12 








 10.4 OUTSTANDING AWARDS – OTHER CHANGES. In the event of any other change in the
capitalization of the Company or corporate change other than those specifically referred to in this Article 10, the Committee may, in its absolute discretion, make such adjustments in the number and class of shares subject to Awards outstanding on
the date on which such change occurs and in the per share grant or exercise price of each Award as the Committee may consider appropriate to prevent dilution or enlargement of rights. 
 10.5 NO OTHER RIGHTS. Except as expressly provided in the Plan, no Participant shall have any rights by reason of any subdivision or
consolidation of shares of stock of any class, the payment of any dividend, any increase or decrease in the number of shares of stock of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other corporation.
Except as expressly provided in the Plan or pursuant to action of the Committee under the Plan, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number of shares of Stock subject to an Award or the grant or exercise price of any Award. 
 ARTICLE 11 
 ADMINISTRATION 
 11.1 COMMITTEE. Unless and until the Board delegates administration to the Committee as set forth below, the Plan shall be administered by the Board, which shall, in such event, constitute the
“Committee” for the purposes of this Plan. Any action taken by the Board in connection with the administration of the Plan shall not be deemed approved by the Board unless such actions are approved by a majority of the Independent
Directors. The Board may delegate administration of the Plan to the Committee, and the term “Committee” shall apply to any person or persons to whom such authority has been delegated; provided, however, that such Committee be
comprised of a majority of or solely two or more Independent Directors. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board,
including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. 
 The Board may abolish the
Committee at any time and revest in the Board the administration of the Plan. Any action taken by the Board in connection with the administration of the Plan shall continue to not be deemed approved by the Board unless such actions are approved by a
majority of the Independent Directors. Appointment of Committee members shall be effective upon acceptance of appointment. Committee members may resign at any time by delivering written notice to the Board. Vacancies in the Committee may only be
filled by the Board. 
 11.2 ACTION BY THE COMMITTEE. A majority of the Committee shall constitute a quorum. The acts of a
majority of the members present at any meeting at which a 

  

 13 








 
quorum is present, and acts approved in writing by a majority of the Committee in lieu of a meeting, shall be deemed the acts of the Committee. Each member
of the Committee is entitled to, in good faith, rely or act upon any report or other information furnished to that member by any officer or other employee of the Company or any Subsidiary, the Company’s independent certified public accountants,
or any executive compensation consultant or other professional retained by the Company to assist in the administration of the Plan. 
 11.3
AUTHORITY OF COMMITTEE. Subject to any specific designation in the Plan, the Committee has the exclusive power, authority and discretion to: 
 (a) Adopt procedures from time to time in the Committee’s discretion to ensure that an Employee is eligible to participate in the Plan prior to the granting of any Awards to such Employee under the Plan
(including, without limitation, a requirement, if any, that each such Employee certify to the Company prior to the receipt of an Award under the Plan that he or she has not been previously employed by the Company or a Subsidiary, or if previously
employed, has had a bona-fide period of non-employment, and that the grant of Awards under the Plan is an inducement material to his or her agreement to enter into employment with the Company or a Subsidiary). 
 (b) Designate Participants to receive Awards; 
 (c) Determine the type or types of Awards to be granted to each Participant; 
 (d) Determine the number of Awards to be granted and
the number of shares of Stock to which an Award will relate; 
 (e) Determine the terms and conditions of any Award granted pursuant to the
Plan, including, but not limited to, the exercise price, grant price, or purchase price, any reload provision, any restrictions or limitations on the Award, any schedule for lapse of forfeiture restrictions or restrictions on the exercisability of
an Award, and accelerations or waivers thereof, any provisions related to non-competition and recapture of gain on an Award, based in each case on such considerations as the Committee in its sole discretion determines; 
 (f) Determine whether, to what extent, and pursuant to what circumstances an Award may be settled in, or the exercise price of an Award may be paid in,
cash, Stock, other Awards, or other property, or an Award may be canceled, forfeited, or surrendered; 
 (g) Prescribe the form of each Award
Agreement, which need not be identical for each Participant; 
 (h) Decide all other matters that must be determined in connection with an
Award; 
 (i) Establish, adopt, or revise any rules and regulations as it may deem necessary or advisable to administer the Plan; 

(j) Interpret the terms of, and any matter arising pursuant to, the Plan or any Award Agreement; and 
  

 14 








 (k) Make all other decisions and determinations that may be required pursuant to the Plan or as the
Committee deems necessary or advisable to administer the Plan. 
 12.4 DECISIONS BINDING. The Committee’s interpretation
of the Plan, any Awards granted pursuant to the Plan, any Award Agreement and all decisions and determinations by the Committee with respect to the Plan are final, binding, and conclusive on all parties. 
 ARTICLE 12 
 EFFECTIVE AND EXPIRATION
DATE 
 12.1 EFFECTIVE DATE. The Plan is effective as of the date of its adoption by the Board (the “Effective
Date”). 
 12.2 EXPIRATION DATE. The Plan will expire on, and no Award may be granted pursuant to the Plan after
December 31, 2005 (the “Expiration Date”). Any Awards that are outstanding on the Expiration Date shall remain in force according to the terms of the Plan and the applicable Award Agreement. Each Award Agreement shall provide
that it will expire on the tenth anniversary of the date of grant of the Award to which it relates. 
 ARTICLE 13 
 AMENDMENT, MODIFICATION, AND TERMINATION 
 13.1 AMENDMENT, MODIFICATION, AND TERMINATION. With the approval of the Board, at any time and from time to time, the Committee may terminate, amend or modify the Plan; provided, however, that to the extent necessary
and desirable to comply with any applicable law, regulation, or stock exchange rule, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. 
 13.2 AWARDS PREVIOUSLY GRANTED. No termination, amendment, or modification of the Plan shall adversely affect in any material way any Award
previously granted pursuant to the Plan without the prior written consent of the Participant. 
 ARTICLE 14 
 GENERAL PROVISIONS 
 14.1 NO
RIGHTS TO AWARDS. No Participant, employee, or other person shall have any claim to be granted any Award pursuant to the Plan, and neither the Company nor the Committee is obligated to treat Participants, employees, and other persons
uniformly. 
 14.2 NO STOCKHOLDERS RIGHTS. No Award gives the Participant any of the rights of a stockholder of the Company
unless and until shares of Stock are in fact issued to such person in connection with such Award. 
 14.3 WITHHOLDING. The
Company or any Subsidiary shall have the authority and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, local and foreign taxes (including the Participant’s FICA
obligation) required by law to be withheld with respect to any taxable event concerning a Participant arising as a result of this Plan. The Committee may in its discretion and in 

  

 15 








 
satisfaction of the foregoing requirement allow a Participant to elect to have the Company withhold shares of Stock otherwise issuable under an Award (or
allow the return of shares of Stock) having a Fair Market Value equal to the sums required to be withheld. Notwithstanding any other provision of the Plan, the number of shares of Stock which may be withheld with respect to the issuance, vesting,
exercise or payment of any Award (or which may be repurchased from the Participant of such Award within six months after such shares of Stock were acquired by the Participant from the Company) in order to satisfy the Participant’s federal,
state, local and foreign income and payroll tax liabilities with respect to the issuance, vesting, exercise or payment of the Award shall be limited to the number of shares which have a Fair Market Value on the date of withholding or repurchase
equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes that are applicable to such supplemental taxable income. 
 14.4 NO RIGHT TO EMPLOYMENT OR SERVICES. Nothing in the Plan or any Award Agreement shall interfere with or limit in any way the right of
the Company or any Subsidiary to terminate any Participant’s employment at any time, nor confer upon any Participant any right to continue in the employ of the Company or any Subsidiary. 
 14.5 UNFUNDED STATUS OF AWARDS. The Plan is intended to be an “unfunded” plan for incentive compensation. With respect to any
payments not yet made to a Participant pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Participant any rights that are greater than those of a general creditor of the Company or any Subsidiary. 

14.6 INDEMNIFICATION. To the extent allowable pursuant to applicable law, each member of the Committee or of the Board shall be
indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he or she may
be a party or in which he or she may be involved by reason of any action or failure to act pursuant to the Plan and against and from any and all amounts paid by him or her in satisfaction of judgment in such action, suit, or proceeding against him
or her, provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be
exclusive of any other rights of indemnification to which such persons may be entitled pursuant to the Company’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them
or hold them harmless. 
 14.7 RELATIONSHIP TO OTHER BENEFITS. No payment pursuant to the Plan shall be taken into account in
determining any benefits pursuant to any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except to the extent otherwise expressly provided in writing in such other plan or
an agreement thereunder. 
 14.8 EXPENSES. The expenses of administering the Plan shall be borne by the Company and its
Subsidiaries. 
  

 16 








 14.9 TITLES AND HEADINGS. The titles and headings of the Sections in the Plan are for
convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. 
 14.10 FRACTIONAL SHARES. No fractional shares of Stock shall be issued and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be
eliminated by rounding up or down as appropriate. 
 14.11 LIMITATIONS APPLICABLE TO SECTION 16 PERSONS. Notwithstanding any
other provision of the Plan, the Plan, and any Award granted or awarded to any Participant who is then subject to Section 16 of the Exchange Act, shall be subject to any additional limitations set forth in any applicable exemptive rule under
Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, the Plan and Awards granted or awarded
hereunder shall be deemed amended to the extent necessary to conform to such applicable exemptive rule. 
 14.12 GOVERNMENT AND OTHER
REGULATIONS. The obligation of the Company to make payment of awards in Stock or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by government agencies as may be required. The Company shall be
under no obligation to register pursuant to the Securities Act of 1933, as amended, any of the shares of Stock paid pursuant to the Plan. If the shares paid pursuant to the Plan may in certain circumstances be exempt from registration pursuant to
the Securities Act of 1933, as amended, the Company may restrict the transfer of such shares in such manner as it deems advisable to ensure the availability of any such exemption. 
 14.13 GOVERNING LAW. The Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of
Delaware. 
 ARTICLE 15 
 GENERAL PROVISIONS 
 15.1 STOCKHOLDER APPROVAL NOT REQUIRED. It is expressly intended that approval of the
Company’s stockholders not be required as a condition of the effectiveness of the Plan, and the Plan’s provisions shall be interpreted in a manner consistent with such intent for all purposes. Specifically, Rule 4350(i) promulgated by the
NASD generally requires stockholder approval for stock option plans or other equity compensation arrangements adopted by companies whose securities are listed on the Nasdaq National Market pursuant to which stock awards or stock may be acquired by
officers, directors, employees, or consultants of such companies. NASD Rule 4350(i)(1)(A)(iv) provides an exception to this requirement for issuances of securities to a person not previously an employee or director of the issuer, or following a bona
fide period of non-employment, as an inducement material to the individual’s entering into employment with the issuer, provided such issuances are approved by either the issuer’s compensation committee comprised of a majority of
independent directors or a majority 

  

 17 








 
of the issuer’s independent directors. Awards under this Plan may only be made to Eligible Participants who have not previously been an Employee or
director of the Company or a Subsidiary, or following a bona fide period of non-employment by the Company or a Subsidiary, as an inducement material to the Eligible Participant’s entering into employment with the Company or a Subsidiary. Awards
under the Plan will be approved by (i) the Company’s Compensation Committee comprised of a majority of the Company’s Independent Directors or (ii) a majority of the Company’s Independent Directors. Accordingly, pursuant to
NASD Rule 4350(i)(1)(A)(iv), the issuance of Awards and the shares of Common Stock issuable upon exercise or vesting of such Awards pursuant to this Plan are not subject to the approval of the Company’s stockholders.

 STOCK OPTION AGREEMENT PAGE 2 








 ARTICLE IV 
 EXERCISE OF OPTION 
 4.1 Person Eligible to Exercise. Except as provided in Sections 5.2(b)
and 5.2(c), during the lifetime of the Optionee, only the Optionee may exercise the Option or any portion thereof. After the death of the Optionee, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable
under Section 3.3, be exercised by the Optionee’s beneficiary designated in accordance with Section 9.4 of the Plan. If no beneficiary has been designated or survives the Optionee, the Option may be exercised by the person entitled to
such exercise pursuant to the Optionee’s will or the laws of descent and distribution. 
 4.2 Partial Exercise. Any exercisable
portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes unexercisable under Section 3.3. 
 4.3 Manner of Exercise. The Option, or any exercisable portion thereof, may be exercised solely by delivery to the Secretary of the Company or the
Secretary’s office of all of the following prior to the time when the Option or such portion thereof becomes unexercisable under Section 3.3: 
 (a) An Exercise Notice in writing signed by the Optionee or the other person then entitled to exercise the Option or portion thereof, stating that the Option or portion thereof is thereby exercised, such notice
complying with all applicable rules established by the Committee. Such notice shall be substantially in the form attached as Exhibit A (or such other form as is prescribed by the Committee); and 
 (b)    (i) Full payment (in cash or by check) for the shares with respect to which the Option or portion thereof is
exercised, to the extent permitted under applicable laws; or 
 (ii) To the extent permitted under applicable laws, through
the delivery of a notice that the Optionee has placed a market sell order with a broker with respect to shares of Stock then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds
of the sale to the Company in satisfaction of the Option exercise price, provided, that payment of such proceeds is made to the Company upon settlement of such sale; or 
 (iii) With the consent of the Committee, any combination of the consideration provided in the foregoing subparagraphs (i) and (ii);
and 
 (c) A bona fide written representation and agreement, in such form as is prescribed by the Committee, signed by the Optionee or other
person then entitled to exercise such Option or portion thereof, stating that the shares of Stock are being acquired for the Optionee’s own account, for investment and without any present intention of distributing or reselling said shares or
any of them except as may be permitted under the Securities Act of 1933, as amended (the “Securities Act”), and then applicable rules and regulations thereunder, and that the Optionee or other person then entitled to exercise
such Option or portion thereof will indemnify the Company against and hold it free and harmless from any loss, damage, expense or liability resulting to the Company if any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Committee may, in its absolute discretion, take whatever additional actions it deems appropriate to ensure the observance and performance of such representation and agreement and to effect
compliance with the Securities Act and 

  

 STOCK OPTION AGREEMENT PAGE 3 








 
any other federal or state securities laws or regulations. Without limiting the generality of the foregoing, the Committee may require an opinion of counsel
acceptable to it to the effect that any subsequent transfer of shares acquired on an Option exercise does not violate the Securities Act, and may issue stop-transfer orders covering such shares. Share certificates evidencing Stock issued on exercise
of the Option shall bear an appropriate legend referring to the provisions of this subsection (c) and the agreements herein. The written representation and agreement referred to in the first sentence of this subsection (c) shall, however,
not be required if the shares to be issued pursuant to such exercise have been registered under the Securities Act, and such registration is then effective in respect of such shares; and 
 (d) Full payment to the Company (or other employer corporation) of all amounts which, under federal, state, local or foreign tax law, it is required to
withhold upon exercise of the Option. With the consent of the Committee, shares of Stock issuable to the Optionee upon exercise of the Option, having a Fair Market Value at the date of Option exercise equal to the statutory minimum sums required to
be withheld, may be used to make all or part of such payment; and 
 (e) In the event the Option or portion thereof shall be exercised
pursuant to Section 4.1 by any person or persons other than the Optionee, appropriate proof of the right of such person or persons to exercise the Option. 
 4.4 Conditions to Issuance of Stock Certificates. The shares of Stock deliverable upon the exercise of the Option, or any portion thereof, shall be fully paid and nonassessable. The Company shall not be
required to issue or deliver any certificate or certificates for shares of Stock purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the following conditions: 
 (a) The admission of such shares to listing on all stock exchanges on which such Stock is then listed; and 
 (b) The completion of any registration or other qualification of such shares under any state or federal law or under rulings or regulations of the
Securities and Exchange Commission or of any other governmental regulatory body, which the Committee shall, in its absolute discretion, deem necessary or advisable; and 
 (c) The obtaining of any approval or other clearance from any state or federal governmental agency which the Committee shall, in its absolute discretion, determine to be necessary or advisable; and 
 (d) The receipt by the Company of full payment for such shares, including payment of all amounts which, under federal, state or local tax law, the
Company (or other employer corporation) is required to withhold upon exercise of the Option; and 
 (e) The lapse of such reasonable period
of time following the exercise of the Option as the Committee may from time to time establish for reasons of administrative convenience. 
 4.5 Rights as Stockholder. The holder of the Option shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any shares purchasable upon the exercise of any part of the Option unless and
until certificates representing such shares shall have been issued by the Company to such holder. 
  

 STOCK OPTION AGREEMENT PAGE 4 








 ARTICLE V 
 OTHER PROVISIONS 
 5.1 Administration. The Committee shall have the power to interpret the
Plan and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules. All actions taken and all interpretations and
determinations made by the Committee in good faith shall be final and binding upon the Optionee, the Company and all other interested persons. No member of the Committee shall be personally liable for any action, determination or interpretation made
in good faith with respect to the Plan, this Agreement or the Option. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement; provided,
however, any action taken by the Board in connection with the administration of the Plan shall not be deemed approved by the Board unless such actions are approved by a majority of the Independent Directors. 
 5.2 Option Not Transferable. 
 (a)
Subject to Section 5.2(b), the Option may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution unless and until the Option has been exercised, or the shares underlying such
Option have been issued, and all restrictions applicable to such shares have lapsed. Neither the Option nor any interest or right therein shall be liable for the debts, contracts or engagements of the Optionee or his or her successors in interest or
shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any
other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect, except to the extent that such disposition is permitted by the preceding sentence. 
 (b) Notwithstanding any other provision in this Agreement, with the consent of the Committee, the Option may be transferred to, exercised by and paid to
certain persons or entities related to the Optionee, including but not limited to members of the Optionee’s family, charitable institutes or trusts or other entities whose beneficiaries or beneficial owners are members of the Optionee’s
family or to such other persons or entities as may be expressly approved by the Committee (each a “Permitted Transferee”), pursuant to such conditions and procedures as the Committee may require. 
 (c) Unless transferred to a Permitted Transferee in accordance with Section 5.2(b), during the lifetime of the Optionee, only the Optionee may
exercise the Option or any portion thereof. Subject to such conditions and procedures as the Committee may require, a Permitted Transferee may exercise the Option or any portion thereof during the Optionee’s lifetime. After the death of the
Optionee, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.3, be exercised by the Optionee’s beneficiary designated in accordance with Section 9.4 of the Plan. If no
beneficiary has been designated or survives the Optionee, the Option may be exercised by the person entitled to such exercise pursuant to the Optionee’s will or the laws of descent and distribution. 
  

 STOCK OPTION AGREEMENT PAGE 5 








 5.3 Restrictive Legends and Stop-Transfer Orders. 
 (a) The share certificate or certificates evidencing the shares of Stock purchased hereunder shall be endorsed with any legends that may be required by
state or federal securities laws. 
 (b) The Optionee agrees that, in order to ensure compliance with the restrictions referred to herein,
the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 
 (c) The Company shall not be required: (i) to transfer on its books any shares of Stock that have been sold or otherwise transferred in violation of
any of the provisions of this Agreement, or (ii) to treat as owner of such shares of Stock or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such shares shall have been so transferred. 
 5.4 Shares to Be Reserved. The Company shall at all times during the term of the Option reserve and keep available such number of shares of Stock
as will be sufficient to satisfy the requirements of this Agreement.

Agreement to the Company shall be addressed to the Company in care of the Secretary, and any notice to be given to the Optionee shall be addressed to the Optionee at the address given beneath the Optionee’s signature on the Grant Notice. By a
notice given pursuant to this Section 5.5, either party may hereafter designate a different address for notices to be given to that party. Any notice which is required to be given to the Optionee shall, if the Optionee is then deceased, be
given to the Optionee’s designated beneficiary if any, or the person otherwise entitled to exercise his or her Option pursuant to Section 4.1 by written notice under this Section 5.5. Any notice shall be deemed duly given when
sent via email or enclosed in a properly sealed envelope or wrapper addressed as aforesaid and deposited (with postage prepaid) in a post office or branch post office regularly maintained by the United States Postal Service. 
 5.6 Titles. Titles are provided herein for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

 5.7 Stockholder Approval Not Required. The Plan will not be submitted for approval by the Company’s stockholders. As more
particularly described in Section 15.1 of the Plan, pursuant to NASD Rule 4350(i)(1)(A)(iv), the issuance of this Option and the shares of Common Stock issuable upon exercise or vesting of such Option pursuant to the Plan are not subject to the
approval of the Company’s stockholders. 
 5.8 Construction. This Agreement shall be administered, interpreted and enforced under
