minutes of its meetings. The Committee shall have all of the powers necessary to enable it to carry out its duties under the Plan
properly, including the power and duty to construe and interpret the Plan and to determine all questions arising under it. The
Committee may correct any defect, supply any omission, or reconcile any inconsistency in the Plan or in any Option in the manner
and to the extent it deems necessary to carry out the intent of the Plan. The Committee’s interpretations and determinations
shall be final, binding and conclusive upon all Persons. The Committee may also establish, from time to time, such regulations,
provisions, procedures, and conditions regarding the Options and granting of Options, which in its opinion may be advisable in
administering the Plan. The acts of a majority of the total membership of the Committee at any meeting, or the acts approved in
writing by all of its members, shall be the acts of the Committee.

Subject to the express terms and conditions set forth herein, the Committee shall have the power from time to time to:

respect to the Plan.

 

3.4     Non-Uniform
Determinations. The Committee’s determinations under the Plan need not be uniform and may be made by it selectively among
Persons who receive, or are eligible to receive Options (whether or not such Persons are similarly situated). Without limiting
the generality of the foregoing, the Committee shall be entitled, among other things, to make non-uniform and selective determinations,
and to enter into non-uniform and selective Option Agreements, as to the Eligible Individuals to receive Options under the Plan
and the terms and provision of Options under the Plan. All decisions and determinations by the Committee in the exercise of the
above powers shall be final, binding and conclusive upon the Company, its Subsidiaries, the Participants and all other persons
having any interest therein. Notwithstanding anything herein to the contrary, with respect to Participants working outside the
United States, the Committee may determine the terms and conditions of Options and make such adjustments to the terms thereof as
are necessary or advisable to fulfill the purposes of the Plan taking into account matters of local law or practice, including
tax and securities laws of jurisdictions outside the United States.

 

3.5     Indemnification.
No member of the Committee shall be liable for any action, failure to act, determination or interpretation made in good faith with
respect to the Plan or any transaction hereunder. The Company hereby agrees to indemnify each member of the Committee for all costs
and expenses and, to the extent permitted by applicable law, any liability incurred in connection with defending against, responding
to, negotiating for the settlement of or otherwise dealing with any claim, cause of action or dispute of any kind arising in connection

held by it as treasury shares. The aggregate number of Shares that may be made the subject of Options granted under the Plan shall
not exceed 59,238.

 

    	-5-

    	 

    

4.2     Calculating
Shares Available. The Committee shall determine the appropriate method for determining the number of Shares available for grant
under the Plan, subject to the following:

 

(a)     Except
as provided in Section 4.2(b), the number of Shares available under this Section 4 for the granting of further Options shall be
reduced by the number of Shares in respect of which the Option is granted or denominated.

 

(b)     Any
Shares related to an Option granted under this Plan that terminates by expiration, forfeiture, cancellation or otherwise without
the issuance of the Shares shall again be available for award under this Plan.

 

5.             Stock
Options.

 

5.1     Authority of Committee.
The Committee may grant Options to Eligible Individuals in accordance with the Plan, and the terms and conditions of the grant
of which shall be set forth in an Option Agreement.

 

5.2     Option Price.
The Option Price or the manner in which the exercise price is to be determined for Shares under each Option shall be determined
by the Committee and set forth in the Option Agreement.

 

5.3     Maximum Duration.
Options granted hereunder shall be for such term as the Committee shall determine; provided that an Option shall not be
exercisable after the expiration of 10 years from the date it is granted; provided, further, however, that unless the Committee
provides otherwise, an Option may, upon the death of the Participant prior to the expiration of the Option, be exercised for up
to 180 days following the date of the Participant’s death, even if such period extends beyond 10 years from the date the
Option is granted. The Committee may, subsequent to the granting of any Option, extend the period within which the Option may be
exercised (including following a Participant’s Termination), but in no event shall the period be extended to a date that
is later than the earlier of the latest date on which the Option could have been exercised and the 10th anniversary
of the date of grant of the Option.

 

5.4     Vesting.
The Committee shall determine and set forth in the applicable Option Agreement the time or times at which an Option shall become
vested and exercisable. To the extent not exercised, vested installments shall accumulate and be exercisable, in whole or in part,
at any time after becoming exercisable, but not later than the date the Option expires. The Committee may accelerate the exercisability
of any Option or portion thereof at any time.

 

5.5     Method of Exercise.
The exercise of an Option shall be made only by giving notice in the form and to the Person designated by the Company, specifying
the number of Shares to be exercised and, to the extent applicable, accompanied by payment therefor and otherwise in accordance
with the Option Agreement pursuant to which the Option was granted. The Option Price shall be paid in any combination of the following
forms: (a) cash or its equivalent (e.g., a check) or (b) other property as determined by the Committee. Any Shares transferred
to or withheld by the Company as payment of the exercise price under an Option shall be valued at their Fair Market Value on the
last business day preceding the date of exercise of such Option. If requested by the Committee, the Participant shall deliver the
Option Agreement evidencing the Option to the Company, which shall endorse thereon a notation of such exercise and return such
Agreement to the Participant.

 

    	-6-

    	 

    

5.6     Rights of Participants.
No Participant shall be deemed for any purpose to be the owner of any Shares subject to any Option unless and until (a) the Option
shall have been exercised pursuant to the terms thereof, (b) the Company shall have issued and delivered Shares (whether or not
certificated) to the Participant, (c) the Participant’s name, or the name of his or her broker or other nominee, shall
have been entered as a shareholder of record on the books of the Company and (d) the Participant shall have entered into the Stockholders’
Agreement. Thereupon, the Participant shall have full voting, dividend and other ownership rights with respect to such Shares,
subject to such terms and conditions as may be set forth in the applicable Option Agreement.

 

6.             Effect
of a Termination; Transferability. 

 

6.1     Termination.
The Option Agreement evidencing the grant of each Option shall set forth the terms and conditions applicable to such Option upon
Termination, which shall be as the Committee may, in its discretion, determine at the time the Option is granted or at anytime
thereafter, and which terms and conditions may include provisions regarding the treatment of an Option in the event of a Termination
by reason of a divestiture of any Subsidiary or Division or other assets of the Company or any Subsidiary.

 

6.2     Transferability of Options and Shares.

 

(a)     Non-Transferability
of Options. Except as set forth in Section 6.2(c) or (d) or as otherwise permitted by the Committee and as set forth in the
applicable Option Agreement, either at the time of grant or at anytime thereafter, no Option shall be (i) sold, transferred or
otherwise disposed of, (ii) pledged or otherwise hypothecated or (iii) subject to attachment, execution or levy of any kind; and
any purported transfer, pledge, hypothecation, attachment, execution or levy in violation of this Section 6.2 shall be null and
void.

 

(b)     Restrictions
on Shares. The Committee may impose such restrictions on any Shares acquired by a Participant under the Plan as it may deem
advisable, including, without limitation, minimum holding period requirements, restrictions under applicable federal securities
laws, restrictions under the requirements of any stock exchange or market upon which such Shares are then listed or traded and
restrictions under any blue sky or state securities laws applicable to such Shares.

 

(c)     Transfers
By Will or by Laws of Descent or Distribution. Any Option may be transferred by will or by the laws of descent or distribution;
provided, however, that (i) any transferred Option will be subject to all of the same terms and conditions as provided in
the Plan and the applicable Option Agreement; and (ii) the Participant’s estate or beneficiary appointed in accordance with
this Section 6.2(c) will remain liable for any withholding tax that may be imposed by any federal, state or local tax authority.

 

(d)     Beneficiary
Designation. Each Participant may, from time to time, name one or more individuals (each, a “Beneficiary”) to whom
any benefit under the Plan is to be paid or who may exercise any rights of the Participant under any Option granted under the Plan
in the event of the Participant’s death before he or she receives any or all of such benefit or exercises such Option. Each
such designation shall 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. In the
absence of any such designation, benefits under Option Agreements remaining unpaid at the Participant’s death and rights
to be exercised following the Participant’s death shall be paid to or exercised by the Participant’s estate.

 

    	-7-

    	 

    

7.             Adjustment
upon Changes in Capitalization.

 

7.1     In the event of
a Change in Capitalization, the Committee shall conclusively determine the appropriate adjustments, if any, to (a) the maximum
number and class of Shares with respect to which Options may be granted under the Plan and (b) the number and class of Shares or
other stock or securities (of the Company or any other corporation or entity), cash or other property which are subject to outstanding
Options granted under the Plan and the exercise price therefor, if applicable.

 

7.2     If, by reason
of a Change in Capitalization, pursuant to an Option Agreement, a Participant shall be entitled to, or shall be entitled to exercise
an Option with respect to, new, additional or different shares of stock or securities of the Company or any other corporation,
such new, additional or different shares shall thereupon be subject to all of the conditions and restrictions which were applicable
to the Shares subject to the Option prior to such Change in Capitalization.

 

8.             Effect
of Certain Transactions. 

 

8.1     Except as otherwise
provided in the applicable Option Agreement, in the event of a Corporate Transaction, all outstanding Options shall terminate upon
the consummation of the Corporate Transaction, unless provision is made in connection with such transaction, in the sole discretion
of the Committee or the parties to the Corporate Transaction, for the assumption or continuation of such Options by, or the substitution
for such Options with new awards of stock options, stock appreciation rights or other equity based compensation of the surviving,
or successor or resulting entity, or a parent or subsidiary thereof, with such adjustments as to the number and kind of shares
or other securities or property subject to such new awards, option and stock appreciation right exercise or base prices, and other
terms of such new awards as the Committee or the parties to the Corporate Transaction shall agree. In the event that provision
is made in writing as aforesaid in connection with a Corporate Transaction, the Plan and the unexercised Options theretofore granted
or the new awards substituted therefor shall continue in the manner and under the terms provided in such writing. Notwithstanding
the foregoing, vested Options (including those Options that would become vested upon the consummation of the Corporate Transaction)
shall not be terminated upon the consummation of the Corporate Transaction unless holders of affected Options are provided either
(a) a period of at least 15 calendar days prior to the date of the consummation of the Corporate Transaction to exercise the Options,
or (b) payment (in cash or other consideration upon or following the consummation of the Corporate Transaction, or, to the extent
permitted by Section 409A of the Code, on a deferred basis) in respect of each Share covered by the Option being cancelled
in an amount equal to the excess, if any, of the per Share price to be paid or distributed to stockholders in the Corporate Transaction
(the value of any non-cash consideration to be determined by the Committee in good faith) over the Option Price of the Option.
For the avoidance of doubt, if the amount determined pursuant to the foregoing is zero or less, the affected Option may be cancelled
without any payment therefor.

 

8.2     Without limiting
the generality of the foregoing or being construed as requiring any such action, in connection with any such Corporate Transaction
the Committee may, in its sole and absolute discretion, cause any of the following actions to be taken effective upon or at any
time prior to any Corporate Transaction (and any such action may be made contingent upon the occurrence of the Corporate Transaction):

 

(a)     cause
any or all unvested Options to become fully vested and immediately exercisable (as applicable) and/or provide the holders of such
Options a reasonable period of time prior to the date of the consummation of the Corporate Transaction to exercise the Options;

 

    	-8-

    	 

    

(b)     with
respect to unvested Options that are terminated in connection with the Corporation Transaction, provide the holders thereof a payment
(in cash and/or other consideration) in respect of each Share covered by the Option being terminated in an amount equal to all
or a portion of the excess, if any, of the per Share price to be paid or distributed to stockholders in the Corporate Transaction
(the value of any non-cash consideration to be determined by the Committee in good faith) over the Option Price of the Option,
which may be paid in accordance with the vesting schedule of the Option as set forth in the applicable Option Agreement, upon
the consummation of the Corporate Transaction or, to the extent permitted by Section 409A of the Code, at such other time
or times as the Committee may determine.

 

8.3     In addition, in
connection with any Corporate Transaction:

 

(a)     Notwithstanding
anything to the contrary, the Committee may, in its sole discretion, provide in the transaction agreement or otherwise for different
treatment for Options held by different Participants and, where alternative treatment is available for a Participant’s Options,
may allow the Participant to choose which treatment shall apply to such Participant’s Options;

 

(b)     Any
action permitted under this Section 8 may be taken without the need for the consent of any Participant. To the extent a Corporate
Transaction also constitutes a Change in Capitalization and action is taken pursuant to this Section 8 with respect to an
outstanding Option, such action shall conclusively determine the treatment of such Option in connection with such Corporate Transaction
notwithstanding any provision of the Plan to the contrary (including Section 7); and

 

(c)     The
Committee may require a Participant to return a letter of transmittal or similar acknowledgment as a condition to receiving any
payment in respect of his or her Options in connection with a Corporate Transaction, in which case any Participant who has not
returned any such letter or similar acknowledgment within the time period established by the Committee for returning any such letter
or similar acknowledgement shall forfeit his or her right to any payment and his or her associated Options may be cancelled without
any payment therefor.

 

9.             Interpretation.
All Options granted under the Plan are intended either not to be subject to Section 409A of the Code or, if subject to Section 409A
of the Code, to be administered, operated and construed in compliance with Section 409A of the Code and all regulations and
other guidance issued thereunder. Notwithstanding this or any other provision of the Plan to the contrary, the Committee may amend
the Plan or any Option granted hereunder in any manner or take any other action that it determines, in its sole discretion, is
necessary, appropriate or advisable (including replacing any Option) to cause the Plan or any Option granted hereunder to comply
with Section 409A of the Code and all regulations and other guidance issued thereunder or to not be subject to Section 409A
of the Code. Any such action, once taken, shall be deemed to be effective from the earliest date necessary to avoid a violation
of Section 409A of the Code and shall be final, binding and conclusive on all Eligible Individuals and other individuals having
or claiming any right or interest under the Plan.

 

10.            Termination
and Amendment of the Plan or Modification of Options.

 

10.1     Effective
Date and Duration of the Plan. The Plan shall be effective on the Effective Date. The Plan shall terminate on the Plan Termination
Date and no Option shall be granted after that date. The applicable terms of the Plan and any terms and conditions applicable to
Options granted prior to the Plan Termination Date shall survive the termination of the Plan and continue to apply to such Options.

 

    	-9-

    	 

    

10.2     Plan Amendment
or Plan Termination. The Board may earlier terminate the Plan and the Board may at any time and from time to time amend, modify
or suspend the Plan; provided, however, that:

 

(a)     no
such amendment, modification, suspension or termination shall impair or adversely alter any Options theretofore granted under the
Plan, except with the consent of the Participant, nor shall any amendment, modification, suspension or termination deprive any
Participant of any Shares which he or she may have acquired through or as a result of the Plan; and

 

(b)     to
the extent necessary under any applicable law, regulation or exchange requirement, no other amendment shall be effective unless
approved by the shareholders of the Company in accordance with applicable law, regulation or exchange requirement.

 

10.3     Modification
of Options. No modification of an Option shall adversely alter or impair any rights or obligations under the Option without
the consent of the Participant.

 

11.            Non-Exclusivity
of the Plan.

 

The adoption of the Plan
by the Board shall not be construed as amending, modifying or rescinding any previously approved incentive arrangement or as creating
any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without
limitation, the granting of stock options otherwise than under the Plan, and such arrangements may be either applicable generally
or only in specific cases.

 

12.            Limitation
of Liability. 

 

As illustrative of the
limitations of liability of the Company, but not intended to be exhaustive thereof, nothing in the Plan shall be construed to:

 

(a)     give
any Person any right to be granted an Option other than at the sole discretion of the Committee;

 

(b)     give
any Person any rights whatsoever with respect to Shares except as specifically provided in the Plan;

 

(c)     limit
in any way the right of the Company or any of its Subsidiaries to terminate the employment of or the provision of services by any
Person at any time; or

 

(d)     be
evidence of any agreement or understanding, express or implied, that the Company will pay any Person at any particular rate of
compensation or for any particular period of time.

 

13.            Regulations
and Other Approvals; Governing Law.

    	-10-

    	 

    

13.2     Compliance
with Law.

 

(a)     The
obligation of the Company to sell or deliver Shares with respect to Options granted under the Plan shall be subject to all applicable
laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals
by governmental agencies as may be deemed necessary or appropriate by the Committee.

 

(b)     The
Board may make such changes as may be necessary or appropriate to comply with the rules and regulations of any government authority.

 

(c)     Each
grant of an Option and the issuance of Shares in settlement of the Option is subject to compliance with all applicable federal,
state and foreign law. Further, if at any time the Committee determines, in its discretion, that the listing, registration or qualification
of Shares issuable pursuant to the Plan is required by any securities exchange or under any federal, state or foreign law, or that
the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with,
the grant of an Option or the issuance of Shares, no Options shall be or shall be deemed to be granted or payment made or Shares
issued, in whole or in part, unless listing, registration, qualification, consent or approval has been effected or obtained free
of any conditions that are not acceptable to the Committee. Any Person exercising an Option shall make such representations and
agreements and furnish such information as the Board or Committee may request to assure compliance with the foregoing or any other
applicable legal requirements.

 

13.3     Transfers
of Plan Acquired Shares. Notwithstanding anything contained in the Plan or any Option Agreement to the contrary, in the event
that the disposition of Shares acquired pursuant to the Plan is not covered by a then current registration statement under the
Securities Act and is not otherwise exempt from such registration, such Shares shall be restricted against transfer to the extent
required by the Securities Act and Rule 144 or other regulations promulgated thereunder. The Committee may require any individual
receiving Shares pursuant to an Option granted under the Plan, as a condition precedent to receipt of such Shares, to represent
and warrant to the Company in writing that the Shares acquired by such individual are acquired without a view to any distribution
thereof and will not be sold or transferred other than pursuant to an effective registration thereof under the Securities Act or
pursuant to an exemption applicable under the Securities Act or the rules and regulations promulgated thereunder. The certificates
evidencing any of such Shares shall be appropriately amended or have an appropriate legend placed thereon to reflect their status
as restricted securities as aforesaid.

 

14.            Miscellaneous.

 

14.1     Forfeiture
Events; Clawback. The Committee may specify in an Option Agreement that the Participant’s rights, payments and benefits
with respect to an Option shall be subject to reduction, cancellation, forfeiture, clawback or recoupment upon the occurrence of
certain specified events or as required by law, in addition to any otherwise applicable forfeiture provisions that apply to the
Option.

 

14.2     Multiple Agreements.
The terms of each Option may differ from other Options granted under the Plan at the same time, or at some other time. The Committee
may also grant more than one Option to a given Eligible Individual during the term of the Plan, either in addition to, or in substitution
for, one or more Options previously granted to that Eligible Individual.

 

    	-11-

    	 

    

14.3     Withholding
of Taxes. The Company or any of its Subsidiaries may withhold from any payment of cash or Shares to a Participant or other
Person under the Plan an amount sufficient to cover any withholding taxes which may become required with respect to such payment
or shall take any other action as it deems necessary to satisfy any income or other tax withholding requirements as a result of
the grant or exercise of any Option under the Plan. The Company or any of its Subsidiaries shall have the right to require the
payment of any such taxes and require that any Person furnish information deemed necessary by the Company or any of its Subsidiaries
to meet any tax reporting obligation as a condition to exercise or before making any payment pursuant to an Option. In addition,
if approved by the Committee, a Participant may elect to (a) have withheld a portion of the Shares then issuable to him or her,
or (b) surrender Shares owned by the Participant prior to the exercise, vesting or other settlement of an Option, in each case
having an aggregate Fair Market Value equal to the withholding taxes.

 

14.4     Plan Unfunded.
The Plan shall be unfunded. Except for reserving a sufficient number of authorized Shares to the extent required by law to meet
the requirements of the Plan, the Company shall not be required to establish any special or separate fund or to make any other
segregation of assets to assure payment of any Option granted under the Plan.

by Section 5.2 of this Agreement, the Optionee’s exercise shall not be given effect and the Shares shall not be issued to
the Optionee.

 

5.4.     Shareholder Rights.

any lien, pledge, exchange or otherwise dispose of the Option or any portion thereof other than to the extent permitted by Section
6.2 of the Plan or the Stockholders’ Agreement.

 

7.2.     Proprietary

Information to any Person other than the Company or executives thereof at the time of such disclosure who, in the reasonable judgment
of the Optionee, need to know such Proprietary Information or such other Persons to whom the Optionee has been specifically instructed
to make disclosure by the Board and in all such cases only to the extent required in the course of the Optionee’s service
to the Company or (b) use any Proprietary Information, directly or indirectly, for the Optionee’s own benefit
or for the benefit of any other Person. Upon the Optionee’s Termination, the Optionee will immediately deliver to the Company
all notes, letters, documents and records which may contain Proprietary Information which are then in the Optionee’s possession
or control and will not retain any copies and summaries thereof. All notes, letters, documents, records, tapes and other media
of every kind and description relating to the business, present or otherwise, of the Company or its Affiliates and any copies,
in whole or in part, thereof (collectively, the “Documents”), whether or not prepared by the Optionee, shall
be the sole and exclusive property of the Company. The Optionee will safeguard all Documents and will surrender to the Company
at the time the Optionee’s employment Terminates, or at such earlier time or times as the Board may specify, all Documents
then in the Optionee’s possession or control.

 

7.3.     Non-Competition
and Non-Solicitation. The Optionee agrees that during employment and for the Restricted Period (as defined below), the Optionee
shall not:

 

(a)     whether for compensation

in the stocks, bonds or other securities of, or otherwise become financially interested in, any business, enterprise or other entity
engaged directly or indirectly within the Territory (as defined below) in any Competitive Business (as defined below) activity;
provided, however, that the Optionee shall be permitted to acquire a passive stock or equity interest in such a Competitive
Business provided the stock or other equity interest acquired is not more than one percent of the outstanding interest in such
business. Nothing herein shall prevent the Optionee from engaging in any activity with, or holding a financial interest in, a non-competitive
division, subsidiary or affiliate of a Competitive Business; and

 

    	-3-

    	 

    

(b)     directly or indirectly
through any officer, director, employee, representative or other agent or otherwise, (i) solicit or do business with any customer
or supplier of the Company of whose names he was aware during his employment term (X) in any manner that interferes with such Person’s
financial relationship with the Company, or (Y) in an effort to obtain such Person as a customer, supplier, consultant, salesman,
agent or representative to any other business; or (ii) solicit or interfere with or endeavor to entice away any employee, consultant,
officer, director or executive of the Company who was engaged in such relationship with the Company at any time during the Optionee’s
employment term, (X) in any manner that interferes with such Person’s employment or consulting relationship with the Company
or (Y) in an effort to obtain such Person as a customer, supplier, consultant, salesman, agent or representative to any Competitive
Business.

 

7.4.     Non-Disparagement.
The Optionee shall not at any time make (or cause to be made) to any Person any knowingly disparaging, derogatory or other negative
statement about the Company or its Affiliates. The foregoing shall not be violated by (a) truthful statements in response to legal
process, required governmental testimony or filings, or administrative or arbitral proceedings (including, without limitation,
depositions in connection with such proceedings), or (b) statements that the Optionee in good faith believes are necessary or appropriate
to make in connection with his or her good faith performance of their duties to the Company.

 

7.5.     Right to Terminate
Option. The Optionee understands and agrees that the Company has granted this Option to the Optionee to reward the Optionee
for the Optionee’s future efforts and loyalty to the Company and its Affiliates by giving the Optionee the opportunity to
participate in the potential future appreciation of the Company. Accordingly, if the Optionee (a) engages in any activity prohibited
by Section 7 of this Agreement, (b) breaches or violates any obligations under any Restrictive Agreement to which the Optionee
is a party or (c) is convicted of a felony against the Company or any of its Affiliates, then, in addition to any other rights
and remedies available to the Company, the Company shall be entitled, at its option, exercisable by written notice, to terminate
the Option (including the Vested Portion of the Option), or any unexercised portion thereof, which shall be of no further force
and effect.

 

7.6.     Remedies.
The Optionee specifically acknowledges and agrees that (a) the time, geographic and activity restrictions (as applicable) set forth
in this Section 7 are reasonable and properly required for the protection of the Company and (b) the Company’s remedies under
this Section 7 shall not prevent the Company or any Subsidiary from seeking injunctive or other equitable relief in connection
with the Optionee’s breach of any Restrictive Agreement. In the event that the provisions of this Section 7 should ever be
deemed to exceed the limitation provided by applicable law, then the Optionee and the Company agree that such provisions shall
be reformed to set forth the maximum limitations permitted.

 

7.7.     Severance
Payments. If the Optionee’s employment is Terminated at any time by the Company or a Subsidiary other than for Cause,
the Company shall pay, or shall cause a Subsidiary to pay, to the Optionee, an amount equal to one times the Optionee’s base
salary at the rate in effect immediately prior to the Termination (the “Severance Amount”). The Company’s
obligation to pay the Severance Amount shall be conditioned upon the Optionee’s execution, delivery and non-revocation of
a valid and enforceable general release of claims (the “Release”) within 45 days after the Optionee’s
Termination. The Severance Amount shall be paid in equal installments on the Company’s regular payroll dates occurring during
the 12-month period beginning on the first payroll date following the date on which the Release has become effective; provided,
however, that if the 45-day period discussed in the previous sentence spans two calendar years, payment of the Severance
Amount shall commence to be paid in the second year.

9.3.     Governing
Law; Submission to Jurisdiction; Waiver of Jury Trial.

 

(a)     Governing Law.
This Agreement shall in all respects be governed by, and construed in accordance with, the laws (excluding conflict of laws rules
and principles) of the State of Delaware applicable to agreements made and to be performed entirely within such State, including
all matters of construction, validity and performance.

 

(b)     Submission
to Jurisdiction; Waiver of Jury Trial. Any litigation against any party to this Agreement arising out of or in any way relating
to this Agreement shall be brought in any federal or state court located in the State of New York in New York County and each of
the parties hereby submits to the exclusive jurisdiction of such courts for the purpose of any such litigation; provided, that
a final judgment in any such litigation shall be conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law. Each party irrevocably and unconditionally agrees not to assert (i) any objection
which it may ever have to the laying of venue of any such litigation in any federal or state court located in the State of New
York in New York County, (ii) any claim that any such litigation brought in any such court has been brought in an inconvenient
forum and (iii) any claim that such court does not have jurisdiction with respect to such litigation. To the extent that service
of process by mail is permitted by applicable law, each party irrevocably consents to the service of process in any such litigation
in such courts by the mailing of such process by registered or certified mail, postage prepaid, at its address for notices provided
for herein. Each party hereto irrevocably and unconditionally waives any right to a trial by jury and agrees that either of
them may file a copy of this paragraph with any court as written evidence of the knowing, voluntary and bargained-for agreement
among the parties irrevocably to waive its right to trial by jury in any litigation.

 

9.4.     Specific Performance.
Each of the parties agrees that any breach of the terms of this Agreement will result in irreparable injury and damage to the other
parties, for which there is no adequate remedy at law. Each of the parties therefore agrees that in the event of a breach or any
threat of breach, the other parties shall be entitled to an immediate injunction and restraining order to prevent such breach,
threatened breach or continued breach, and/or compelling specific performance of the Agreement, without having to prove the inadequacy
of money damages as a remedy or balancing the equities between the parties. Such remedies shall be in addition to any other remedies
(including monetary damages) to which the other parties may be entitled at law or in equity. Each party hereby waives any requirement
for the securing or posting of any bond in connection with any such equitable remedy.

 

9.5.     Severability.
Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law and if the rights or obligations
of any party hereto under this Agreement will not be materially and adversely affected thereby, (a) such provision will be
fully severable, (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a part hereof, (c) the remaining provisions of this Agreement will remain in full force and effect and
will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and (d) in lieu of such
illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

Exhibit A

 

Expo
event holdco, inc. 

NOTICE OF
OPTION EXERCISE

 

Subject to
the terms and conditions hereof, the undersigned (the “Purchaser”) hereby elects to exercise his or her option
to purchase __________ shares (the “Shares”) of Expo Event Holdco, Inc. (the “Company”) under
the Expo Event Holdco, Inc. 2013 Stock Option Plan (the “Plan”) and the Stock Option Agreement dated as of _______________,
(the “Option Agreement”). The purchase price for the Shares shall be $______ per Share for a total purchase
price of $__________ (subject to applicable withholding taxes). The Purchaser tenders herewith payment of the full Option Price
in the form of cash, by check or by wire transfer or, if the Purchaser is permitted pursuant to the Option Agreement, by reducing
the number of Shares to be issued to him hereby by that number of Shares having an aggregate Fair Market Value on the date hereof
equal to the aggregate purchase price of the Shares.

 

In connection with the purchase
of Shares, Purchaser represents and covenants the following:

 

1.     Knowledge
and Representation. If the Purchaser is not an “Accredited
Investor” as that term is defined in Rule 501(a)
of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), the Purchaser acknowledges that as soon as reasonably practicable following its delivery of
this notice, the Company will deliver to the Purchaser disclosures intended to satisfy the applicable requirements of Rule 701
of the Securities Act (the “Rule 701 Disclosure”) (to the extent then applicable), in which case the Purchaser understands
that he or she may revoke this Notice of Option Exercise by written notice to the Company until the eighth day following the receipt
of the Rule 701 Disclosure. The Purchaser is relying on his or her own business judgment and knowledge and the advice
of his or her own counsel, tax advisors and other advisors, regarding the risks of an investment in the Company, in making the
decision to purchase the Shares. The Purchaser, either alone or with his or her advisors, has sufficient knowledge and experience
in business and financial matters to evaluate the merits and risks of the purchase of the Shares and has the capacity to protect
his or her own interests in connection with such purchase. In furtherance of the foregoing, the Purchaser represents and warrants
that (i) no representation or warranty, express or implied, whether written or oral, as to the financial condition, results
of operations, prospects, properties or business of the Company or as to the desirability or value of an investment in the Company
has been made to the Purchaser by or on behalf of the Company, and (ii) the Purchaser will continue to bear sole responsibility
for making his or her own independent evaluation and monitoring of the risks of his or her investment in the Company.

 

2.     Investment
Intent. The Purchaser is purchasing the Shares for investment for his or her own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act, or under any applicable
provision of state securities laws. The Purchaser does not have any present intention to transfer the Shares to any person or entity.

 

3.     Securities
Laws; Transfer Restrictions. The Purchaser understands that the Shares have not been registered under the Securities Act by
reason of a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Purchaser’s
investment intent as expressed herein. The Purchaser acknowledges and understands that the Shares must be held indefinitely unless
(i) they are subsequently registered under the Securities Act or any applicable provision of state securities laws or (ii) an exemption
from such registration is available. The Purchaser further acknowledges and understands that the Company is under no obligation
to register the Shares. In addition, the Purchaser acknowledges and understands that there are substantial restrictions on the
transferability of the Shares under the Company’s Stockholders Agreement, dated as of July 19, 2013, as amended from time
to time (the “Stockholders Agreement”). The Purchaser understands that the certificate or certificates evidencing
the Shares will be imprinted with a legend which prohibits the transfer of the Shares except in compliance with the Securities
Act or applicable state securities laws and except in accordance with the provisions of the Stockholders Agreement, and that the
Company will retain physical possession of the Shares as provided in the Stockholders Agreement.

 

    	 

    	 

    

4.     Tax. The
Purchaser understands that he or she may suffer adverse tax consequences as a result of his or her purchase or disposition of the
Shares. The Purchaser represents that he or she has consulted any tax consultants he or she deems advisable in connection with
the purchase or disposition of the Shares and that he or she is not relying on the Company for any tax advice. Purchaser understands
that, prior to the issuance of any Shares, Purchaser will have to make satisfactory arrangements with the Company to satisfy any
withholding requirements applicable to the exercise of the option.

 

5.     Speculative
Investment. The Purchaser understands that an investment in the Shares is a speculative investment which involves a high degree
of risk of loss of the Purchaser’s investment therein. The Purchaser is able to bear the economic risk of such investment
for an indefinite period of time, including the risk of a complete loss of the Purchaser’s investment in such securities.

 

6.     Underwriter
Lock-Up. The Purchaser agrees (i) to the extent requested in writing by a managing underwriter, if any, of any underwritten
public offering pursuant to a registration or offering of equity securities of the Company not to sell, transfer or otherwise dispose
of, including any sale pursuant to Rule 144 under the Securities Act, the Shares, or any other equity security of the Company or
any security convertible into or exchangeable or exercisable for any equity security of the Company (other than as part of such
underwritten public offering) during the time period reasonably requested by the managing underwriter, not to exceed 180 days or
such shorter period as the Company or any executive officer or director of the Company shall agree to and (ii) to the extent requested
in writing by a managing underwriter of any underwritten public offering effected by the Company for its own account, not to sell
the Shares or any other equity securities of the Company (other than as part of such underwritten public offering) during the time
period reasonably requested by the managing underwriter, which period shall not exceed 180 days or such shorter period as the Company
or any executive officer or director of the Company shall agree to.iii

 

 

 

iii
In addition, the Stockholders Agreement will provide that, during the three-year period following an Initial Public Offering, the
Purchaser shall be prohibited from selling a number of Shares that at the time of sale is in excess of the greater of (i) 15% of
the total number of Shares held by Purchaser immediately following the IPO, multiplied by the number of 12-month periods that have
elapsed since the IPO, and (ii) a number of Shares determined by multiplying the number of Shares held by the Purchaser immediately
following the IPO by a percentage determined by subtracting from the number one a fraction, the numerator of which is the number
of Shares held by Onex on the date of the Purchaser’s proposed sale of Shares and the denominator of which is the number
of Shares held by Onex immediately following the IPO.
