(c) Delegation. The Committee may delegate to the Chief Executive Officer and to other senior officers of the Company its duties

SECTION 4. Shares Available for Awards. 

(a) Shares Available. Subject to adjustment as provided in Section 8, the aggregate number of Shares with respect to which
Awards may be granted under the Plan shall be up to 86,301 Shares. If any Award is exercised, paid, forfeited, terminated or canceled without the delivery of Shares to the Participant, then the Shares covered by such Award, to the extent of such

original purchase price shall become available for future grant under the Plan. Notwithstanding the provisions of this Section 4, no Shares may again be optioned, granted or awarded if such action would cause an Incentive Stock Option to fail
to qualify as an incentive stock option under Section 422 of the Code. Awards will not reduce the number of Shares that may be issued pursuant to the Plan if the settlement of the Award will not require the issuance of Shares, as, for example,
an Other Stock-Based Award that can be satisfied only by the payment of cash.

 (b) Sources of Shares Deliverable Under Awards. Any Shares delivered pursuant to an
Award may consist, in whole or in part, of authorized and unissued Shares or of treasury Shares and shall be fully paid and nonassessable.

terms and conditions, as the Committee shall determine, that are not inconsistent with the provisions of the Plan, which shall be set forth in an applicable Award Agreement. 

(i) Exercise Price & Grant Date. Except as provided in Section 8, the exercise price per Share for
the Shares to be issued upon exercise of an Option shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. Notwithstanding the foregoing, an Option may be granted with a per Share exercise price

year (under all plans of the Company and its parent and subsidiary corporations) exceeds $100,000, such Shares in excess of $100,000 shall be classified as nonqualified stock options. No Option that is an incentive stock option shall be exercisable
after the expiration of 10 years from its date of grant. Notwithstanding anything herein to the contrary, in no event shall any person owning stock possessing more than 10% of the total combined voting power of the Company and its Affiliates be
granted an incentive stock option hereunder unless (1) the Option exercise price shall be at least 110% of the Fair Market Value of the Shares subject to such Option at the time the Option is granted and (2) the term during which such
Option is exercisable does not exceed five years from its date of grant.

applicable Award Agreement. 
 (i) Dividends. Dividends paid on Restricted Stock may be paid directly to
the Participant, may be subject to risk of forfeiture and/or transfer restrictions during any period established by the Committee or sequestered and held in a bookkeeping cash account (with or without interest) or reinvested in additional shares of
Common Stock, which account or shares may be subject to the same restrictions as the underlying Award or such other restrictions, all as determined by the Committee in its discretion. 

(ii) Registration. Any Restricted Stock may be evidenced in such manner as the Committee shall deem appropriate,
including, without limitation, book-entry registration or issuance of a stock certificate or certificates. In the event any stock certificate is issued in respect of Restricted Stock granted under the Plan, such certificate shall be registered in
the name of the Participant and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Stock.

 (iii) Forfeiture and Restrictions Lapse. Except as otherwise
determined by the Committee or the terms of the Award Agreement, upon termination of a Participant’s employment (as determined under criteria established by the Committee) for any reason during the applicable Restricted Period, all Restricted

purchase price for Shares repurchased by the Company pursuant to such repurchase right and the rate at which such repurchase right shall lapse shall be determined by the Committee in its sole discretion, and shall be set forth in the Award
Agreement. 
 (c) Performance Awards. The Committee shall have the authority to determine the Participants who shall
receive a Performance Award, which shall be denominated as a cash amount (e.g., $100 per award unit) at the time of grant and confer on the Participant the right to receive payment of such Award, in whole or in part, upon the achievement of such
Performance Objectives during such performance periods as the Committee shall establish with respect to the Award. 

(i) Terms and Conditions. Subject to the terms of the Plan and any applicable Award Agreement, the Committee shall
determine the Performance Objectives to be achieved during any performance period, the length of any performance period, the amount of any Performance Award and the amount of any payment or transfer to be made pursuant to any Performance Award. In
the case of any Performance Award granted to a Covered Person in any calendar year, Performance Objectives shall be designed to be objective and shall otherwise meet the requirements of Section 162(m) of the Code and regulations issued
thereunder (including Treasury Regulation Section 1.162-27 and any successor regulation thereto), including the requirement that the level or levels of performance targeted by the Committee are such that the achievement of Performance
Objectives is “substantially uncertain” at the time of grant. In addition, achievement of Performance Objectives in respect of Performance Awards shall be measured over a performance period of not less than six (6) months and not more
than one year, as specified by the Committee. Performance Objectives in the case of any Performance Award granted to a Covered Person shall be established not later than ninety (90) days after the beginning of any performance period applicable
to such Performance Award, or at such other date as may be required or permitted for “performance-based compensation” under Section 162(m) of the Code. Subject to Section 8, the Committee shall not exercise
discretion to increase any amount payable in respect of a Performance Award which is intended to comply with Section 162(m) of the Code.

Awards, to the extent earned, shall be paid (in cash and/or in Shares, in the sole discretion of the Committee) in a lump sum following the close of the performance period. Except as may otherwise be required under Section 409A of the Code,
payment described in the immediately preceding sentence shall be made no later than the date that is 2 1/2
 months after the end of the year in which the Performance Award is earned and vested under the Plan, and such payment shall not be subject to any election by the Participant to defer the
payment to a later period. To the extent that settlement is to be made in Shares, the amount payable under a Performance Award shall be divided by the Fair Market Value per Share of Common Stock on the determination date and a stock certificate
evidencing the resulting shares of Common Stock (to the nearest full share) shall be delivered to the Participant, or his personal representative, and the value of any fractional shares will be paid in cash. 

(d) Bonus Shares. The Committee shall have the authority, in its discretion, to grant Bonus Shares to Participants upon such terms
and conditions as set forth in an applicable Award Agreement. Each Bonus Share shall constitute a transfer of an unrestricted Share to the Participant, without other payment therefor, as additional compensation for the Participant’s services to
the Company. 
 (e) Phantom Shares. The Committee shall have the authority to grant Awards of Phantom Shares to
Participants upon such terms and conditions as the Committee may determine as set forth in an applicable Award Agreement. 

(i) Terms and Conditions. Each Phantom Share Award shall constitute an agreement by the Company to issue or
transfer a specified number of Shares or pay an amount of cash equal to a specified number of Shares, or a combination thereof to the Participant in the future, subject to the fulfillment during the Restricted Period of such conditions, including
Performance Objectives, if any, as the Committee may specify at the date of grant. During the Restricted Period, the Participant shall not have any right to transfer any rights under the subject Award, shall not have any rights of ownership in the
Phantom Shares and shall not have any right to vote such shares. 
 (f) Cash Awards. The Committee shall have the
authority to determine the Participants to whom Cash Awards shall be granted, the amount, and the terms or conditions, if any, as additional compensation for the Participant’s services to the Company or its Affiliates. If granted, a Cash Award
shall be granted (simultaneously or subsequently) in tandem with another Award and shall entitle a Participant to receive a specified amount of cash from the Company upon such other Award becoming taxable to the Participant, which cash amount may be
based on a formula relating to the anticipated taxable income associated with such other Award and the payment of the Cash Award.

 (g) Other Stock-Based Awards. The Committee may also grant to Participants an Other
Stock-Based Award, which shall consist of a right which is an Award denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares as is deemed by the Committee to be consistent with the purposes
of the Plan. Subject to the terms of the Plan, including the Performance Objectives, if any, applicable to such Award, the Committee shall determine the terms and conditions of any such Other Stock-Based Award as set forth in an applicable Award
Agreement. 
 (h) General. 

(i) Limits on Transfer of Awards. 

(A) Except as provided in (C) below, each Award, and each right under any Award, shall be exercisable as specified in
the terms of the Award Agreement only by the Participant during the Participant’s lifetime, or by the person to whom the Participant’s rights shall pass by will or the laws of descent and distribution. 

(B) Except as provided in (C) below, no Award and no right under any such Award may be assigned, alienated, pledged,
attached, sold or otherwise transferred or encumbered by a Participant otherwise than by will or by the laws of descent and distribution (or, in the case of Restricted Stock, to the Company, except as otherwise determined by the Committee as set
forth in an applicable Award Agreement). Any such attempted or purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void, ineffective and unenforceable against the Company or any Affiliate, and shall give no
right to the purported transferee, and shall at the sole discretion of the Committee result in the forfeiture of the Award with respect to the Award involved in such attempted or perpetual transfer or encumbrance. 

(C) Notwithstanding anything in the Plan to the contrary, to the extent specifically provided by the Committee with
respect to a grant, (1) a nonqualified stock option may be transferred to immediate family members or related family trusts, or similar entities on such terms and conditions as the Committee may establish, and (2) an Award other than an
Incentive Stock Option may be transferred pursuant to a qualified domestic relations order described in Section 414(p) of the Code. 

(D) Awards may be subject to such other limits on transfer as set forth in the Stockholders’ Agreement. 

(ii) Term of Awards. Subject to the terms of the Plan, the term of each Award shall be for such period as may be
determined by the Committee; provided, that in no event shall the term of any Award exceed a period of 10 years from the date of its grant. 

(iii) Share Certificates. All certificates for Shares or other securities of the Company delivered under the Plan
pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange
upon which such Shares or other securities are then listed, and any applicable federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

 

 -10- 








 (iv) Consideration for Grants. Awards may be granted for no cash
consideration or for such consideration as the Committee determines including, without limitation, such minimal cash consideration as may be required by applicable law. 

(v) Delivery of Shares or other Securities upon Payment by Participant of Consideration. No Shares or other
securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement is received by the Company. 

(vi) Section 409A Considerations. To the extent that the Committee determines that any Award granted under the
Plan is subject to Section 409A of the Code, the Award Agreement shall incorporate the terms and conditions required by Section 409A of the Code. To the extent applicable, the Plan and the Award Agreement evidencing such Award shall be
interpreted in accordance with Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of the Plan to the contrary, in the event that the Committee
determines that any Award may be subject to Section 409A of the Code and related Department of Treasury regulations and other interpretive guidance issued thereunder, the Committee may adopt such amendments to the Plan and the Award Agreement
or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Committee determines are necessary or appropriate to (a) exempt the Award from Section 409A
of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury regulations and other
interpretive guidance thereunder and thereby avoid the application of any penalty taxes under such Section.

Termination. 
 Subject to Section 11, except to the extent prohibited by applicable law and unless otherwise
expressly provided in an Award Agreement or in the Plan: 
 (a) Amendments to the Plan. Except as required by applicable
law or the rules of the principal securities exchange or market on which the shares are traded and subject to Section 7(b) below, the Board may amend, alter, suspend, discontinue, or terminate the Plan without the consent of any stockholder,
Participant, other holder or beneficiary of an Award, or other Person. Provided, however, no amendment to the Plan shall be made without the approval of the shareholders given within twelve months before or after action by the Board, that would
increase the total number of shares available for award under the Plan or extend the term of the Plan (except by operation of Section 8 of the Plan). Termination of the Plan shall not affect the Committee’s ability to exercise the powers
granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 
  

 -11- 








 (b) Amendments to Awards. Subject to Section 7(c) below, the Committee may waive
any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided no change, other than pursuant to Section 8, in any Award shall reduce the benefit to Participant without the consent of such Participant. In
no event shall the Committee, if not the Board, take action without the approval of the Board that constitutes a “repricing” of an Option for financial accounting purposes, and any Board-approved repricing shall be
inoperative and ineffective unless and until approved by the stockholders. 
 (c) Unilateral Amendments. The Committee,
in its sole discretion and without the consent of the Participant, may amend (i) any stock-based Award to reflect (1) a change in corporate capitalization, such as a stock split or dividend, (2) a corporate transaction, such as a
corporate merger, a corporate consolidation, any corporate separation (including a spinoff or other distribution of stock or property by a corporation), any corporate reorganization (whether or not such reorganization comes within the definition of
such term in Section 368 of the Code), (3) any partial or complete corporate liquidation, or (4) a change in accounting rules required by the Financial Accounting Standards Board and (ii) any Award that is not intended to meet
the requirements of the performance based compensation exception to Section 162(m) of the Code, to reflect a significant event that the Committee, in its sole discretion, believes to be appropriate to reflect the original intent in the grant of
the Award. 
 (d) Stockholder Approval. The Board shall obtain stockholder approval of any Plan amendment to the extent
necessary and desirable to comply with applicable laws.

(a) In the event that the Committee determines that other than an Equity Restructuring any dividend or other distribution (whether in the
form of cash, Common 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 Common Stock or other securities of the Company, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, or other similar corporate transaction or event, in the Committee’s
sole discretion, affects the Common 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 by the Company to be made available under
the Plan or with respect to any Award, then the Committee shall, in such manner as it may deem equitable, adjust any or all of: 

(i) the number and kind of shares of Common Stock (or other securities or property) with respect to which Awards may be
granted or awarded (including, but not limited to, adjustments of the limitations in Section 4 hereof on the maximum number and kind of shares which may be issued); 

(ii) the number and kind of shares of Common Stock (or other securities or property) subject to outstanding Awards; and

 (iii) the grant or exercise price with respect to any Award. 

 

 -12- 








 (b) In the event of any transaction or event described in Section 8(a) hereof, the
Committee, in its sole discretion, and on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event and either automatically or upon the
Participant’s request, is hereby authorized to take any one or more of the following actions whenever the Committee determines that such action is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits
intended by the Company to be made available under the Plan or with respect to any Award granted or issued under the Plan or to facilitate such transaction or event: 

(i) To provide for either the purchase of any such Award for an amount of cash equal to the amount that could have been
obtained upon the exercise of such Award or realization of the Participant’s rights had such Award been currently exercisable or payable or fully vested or the replacement of such Award with other rights or property selected by the Committee in
its sole discretion; 
 (ii) To provide that such Award shall be exercisable as to all shares covered thereby,
notwithstanding anything to the contrary in the Plan or the provisions of such Award; 
 (iii) To provide that
such Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or
subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices; 
 (iv) To make
adjustments in the number and type of shares of Common Stock (or other securities or property) subject to outstanding Awards, and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding
Awards or Awards which may be granted in the future; and/or 
 (v) To provide that immediately upon the
consummation of such event, such Award shall not be exercisable and shall terminate; provided, that for a specified period of time prior to such event, such Award shall be exercisable as to all Shares covered thereby, and the restrictions
imposed under an Award Agreement upon some or all Shares may be terminated and, in the case of Restricted Stock, some or all shares of such Restricted Stock may cease to be subject to repurchase, notwithstanding anything to the contrary in the Plan
or the provisions of such Award Agreement. 
 (c) In connection with the occurrence of any Equity Restructuring, and
notwithstanding anything to the contrary in Section 8(a) and 8(b) hereof: 
 (i) The number and type of
securities subject to each outstanding Award and the exercise price or grant price thereof, if applicable, will be proportionately adjusted. The adjustments provided under this Section 8(c)(i) shall be nondiscretionary and shall be final and
binding on the affected Participant and the Company. 
 (ii) 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 limitations in Section 4 hereof). 
  

 -13- 








 (d) Subject to Section 4 hereof, the Committee may, in its sole discretion, include
such further provisions and limitations in any Award Agreement or certificate, as it may deem equitable and in the best interests of the Company. 

(e) The existence of the Plan, any Award Agreement and the Awards granted hereunder shall not affect or restrict in any way the right or
power of the Company or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any
issue of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or which are convertible into or
exchangeable for Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. 

SECTION 9. General Provisions. 

(a) No Rights to Awards. No director, Employee, Consultant or other Person shall have any claim to be granted any Award. There is
no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards, and the terms and conditions of Awards need not be the same with respect to each recipient. 

(b) Withholding. The Company or any Affiliate is authorized to withhold from any Award, from any payment due or transfer made
under any Award or under the Plan or from any compensation or other amount owing to a Participant the amount (in cash, Shares, other securities, Shares that would otherwise be issued pursuant to such Award, other Awards or other property) of any
applicable taxes payable in respect of an Award, its exercise, the lapse of restrictions thereon, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Company to satisfy
all obligations for the payment of such taxes. In addition, the Committee may provide, in an Award Agreement, that the Participant shall have the right to direct the Company to satisfy the Company’s tax withholding obligation through the
“constructive” tender of already-owned Shares or the withholding of Shares otherwise to be acquired upon the exercise or payment of such Award. 

(c) No Right to Employment or other Service Relationship. The grant of an Award shall not be construed as giving a Participant the
right to be retained in the employ or service of the Company or any Affiliate. Further, the Company or an Affiliate may at any time dismiss a Participant from employment or other service relationship at any time, free from any liability or any claim
under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement. 
 (d) Governing Law. The
validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be governed by and construed in accordance with the laws of the State of Delaware and applicable federal law. 

 

 -14- 








 (e) Severability. If any provision of the Plan or any Award is or becomes or is
deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to
conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person
or Award and the remainder of the Plan and any such Award shall remain in full force and effect. 
 (f) Other Laws. The
Committee may refuse to issue or transfer any Shares or other consideration under an Award if, acting in its sole discretion, it determines that the issuance of transfer or such Shares or such other consideration might violate any applicable law or
regulation or entitle the Company to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly
refunded to the relevant Participant, holder or beneficiary. 
 (g) Unfunded Plan. Neither the Plan nor the Award shall
create or be construed to create a trust or separate fund or funds. Neither the Plan nor any Award shall establish any kind of a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that
any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or any Affiliate. 

(h) No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee
shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Shares or whether such fractional Shares or any rights thereto shall be canceled, terminated or otherwise eliminated.

 (i) Shareholder Agreements. The Committee may condition the grant, exercise or payment of any Award upon such person
entering into a stockholders’ agreement or repurchase agreement in such form as approved from time to time by the Board. 

(j) Gender, Tense and Headings. Whenever the context requires, words of the masculine gender used herein shall include the
feminine and neuter and words used in the singular shall include the plural. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or
relevant to the construction or interpretation of the Plan or any provision thereof. 
 (k) No Guarantee of Tax
Consequences. None of the Board, the Company nor the Committee makes any commitment or guarantee that any federal, state or local tax treatment will apply or be available to any person participating or eligible to participate hereunder.

 (l) Section 162(m) Special Transition Rule. Should any class of Common Stock be registered under
Section 12(g) of the Exchange Act, the Plan is intended to qualify for the transition relief provided under Treasury Regulation §1.162-27(f). Accordingly, all compensation realized by Participants in connection with Awards granted under
the Plan within the reliance period described therein is intended to be exempt from the limitation on tax deductibility under Section 162(m) of the Code. For purposes of the Plan, the reliance period will expire on the earlier of (i) the
expiration of the Plan, (ii) a “material modification” of the Plan (within the meaning of Treasury Regulation §1.162-27(h)(1)(iii)), (iii) the issuance of all Common Stock that has been allocated under the Plan, or
(iv) the first meeting of stockholders of the Company at which non-employee Directors are to be elected that occurs after the close of the third calendar year following the calendar year in which the Common Stock is first registered under
Section 12(g) of the Exchange Act. 
  

 -15- 








 (m) Repurchase Provisions. The Committee in its sole discretion may provide that the
Company may repurchase Shares acquired upon exercise of an Award upon the occurrence of certain specified events, including, without limitation, a Participant’s termination of service as an Employee, Director or Consultant, divorce, bankruptcy
or insolvency; provided, however, that any such repurchase right shall be set forth in the applicable Award Agreement or in another agreement referred to in such agreement. 

(n) Reservation of Shares. The Company, during the term of the Plan, shall at all times reserve and keep available such number of
Shares as shall be sufficient to satisfy the requirements of the Plan. 
 (o) Investment Intent. The Company may require
a Participant, as a condition of exercising or acquiring Shares under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’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 Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring the Shares subject to the Award for the Participant’s own account and not with any present intention
of selling or otherwise distributing the Shares. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (A) the issuance of the Shares upon the exercise or acquisition of stock under the
applicable Award has been registered under a then currently effective registration statement under the Securities Act or (B) 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 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. 
 SECTION 10. Effective Date of
the Plan. 
 The Plan shall become effective upon its initial adoption by the Board and shall continue in effect until it
is terminated under Section 11. The Plan will be submitted for the approval of the Company’s stockholders within twelve months after the date of the Board’s initial adoption of the Plan. Awards may be granted prior to such stockholder
approval, provided that such Awards shall not be exercisable, shall not vest and the restrictions thereon shall not lapse prior to the time when the Plan is approved by the stockholders, and provided further that if such approval has not been
obtained at the end of said twelve-month period, all Awards previously granted under the Plan shall thereupon be canceled and become null and void.

 (b) No Award granted under the Plan may be materially amended, materially altered or terminated without the prior written
consent of CCMP;

(d) Neither the Board nor the Committee may take any action under Section 3 with respect to senior executive officers without the
prior written consent of CCMP; and 
 (e) CCMP shall be an intended third party beneficiary of, and shall have standing to
enforce the terms of, this Section 11 as if it were a party hereto. 
 SECTION 12. Term of the Plan. 

No Award shall be granted under the Plan after the 10th anniversary of the earlier of the date this Plan is adopted by the Board or the
date the Plan is approved by the stockholders of the Company. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted prior to such termination, and the authority of the Board or the Committee
to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award, shall extend beyond such termination date.
