made with respect to the Plan or any Award hereunder (unless constituting fraud or a willful criminal act or omission). Each
Indemnifiable Person shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or
expense (including attorneys’ fees) that may be imposed upon or incurred by such Indemnifiable Person in connection
with or resulting from any action, suit or proceeding to which such Indemnifiable Person may be a party or in which such
Indemnifiable Person may be involved by reason of any action taken or omitted to be taken or determination made with respect
to the Plan or any Award hereunder and against and from any and all amounts paid by such Indemnifiable Person with the
Company’s approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any
such action, suit or proceeding against such Indemnifiable Person, and the Company shall advance to such Indemnifiable Person
any such expenses promptly upon written request (which request shall include an undertaking by the Indemnifiable Person to
repay the amount of such advance if it shall ultimately be determined, as provided below, that the Indemnifiable Person is
not entitled to be indemnified); provided, that the Company shall have the right, at its own expense, to assume and
defend any such action, suit or proceeding and once the Company gives notice of its intent to assume the defense, the Company
shall have sole control over such defense with counsel of the Company’s choice. The foregoing right of indemnification
shall not be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either
case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts, omissions or
determinations of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable
Person’s fraud or willful criminal act or omission or that such right of indemnification is otherwise prohibited by
Applicable Law or by the organizational documents of any member of the Company Group. The foregoing right of indemnification
shall not be exclusive of or otherwise supersede any other rights of indemnification to which such Indemnifiable Persons may
be entitled under (i) the organizational documents of any member of the Company Group, (ii) pursuant to Applicable Law, (iii)
an individual indemnification agreement or contract or otherwise, or (iv) any other power that the Company may have to
indemnify such Indemnifiable Persons or hold such Indemnifiable Persons harmless.

to one or more Eligible Persons. Participation in the Plan shall be limited to Eligible Persons.

 

6.            
Shares Subject to the Plan; Limitations.

 

(a)           
Share Reserve. Subject to Section 11 of the Plan, 20,000,000 shares of Common Stock (the “Plan Share
Reserve”) shall be available for Awards under the Plan. Each Award granted under the Plan will reduce the Plan Share
Reserve by the number of shares of Common Stock underlying the Award. Notwithstanding the foregoing, the Plan Share Reserve shall
be automatically increased on the first day of each fiscal year following the fiscal year in which the Effective Date falls by
a number of shares of Common Stock equal to the lesser of (i) the positive difference, if any, between (A) 4% of the Outstanding
Common Stock on the last day of the immediately preceding fiscal year, and (B) the Plan Share Reserve on the last day of the immediately
preceding fiscal year, and (ii) the number of shares of Common Stock as may be determined by the Board.

 

(b)            Additional
Limits. Subject to Section 11 of the Plan, (i) no more than the number of shares of Common Stock equal to the Plan Share
Reserve may be issued in the aggregate pursuant to the exercise of Incentive Stock Options granted under the Plan; and (ii)
during a single fiscal year, the number of Awards eligible to be made to a Non-Employee Director, taken together with any
cash fees paid to such Non-Employee Director during such fiscal year in respect of such Director’s service as a member
of the Board during such fiscal year, shall not exceed a total value of $1,000,000 (calculating the value of any such Awards
based on the grant date fair value of such Awards for financial reporting purposes); provided, that the Committee, or
a separate committee of Non-Employee Directors may make exceptions to this limit for a non- executive chair of the Board,
provided that the Non-Employee Director receiving such additional compensation does not participate in the decision to award
such compensation.

 

     

    11

    

 

(c)           
Share Counting. Other than with respect to Substitute Awards, to the extent that an Award expires or is canceled,
forfeited, or terminated without issuance to the Participant of the full number of shares of Common Stock to which the Award related,
the unissued shares underlying such Award will be returned to the Plan Share Reserve and again be available for grant under the
Plan. No Shares shall be deemed to have been issued in settlement of a SAR, Other Equity-Based Award or Restricted Stock Unit that
only provides for settlement in, and settles only in, cash, or in respect of any Cash-Based Incentive Award. Shares of Common Stock
withheld in payment of the Exercise Price or taxes relating to an Award and shares equal to the number of shares of Common Stock
surrendered in payment of any Exercise Price, SAR Base Price, or taxes relating to an Award shall constitute shares of Common Stock
issued to the Participant and shall reduce the Plan Share Reserve.

 

(d)          
Source of Shares. Shares of Common Stock issued by the Company in settlement of Awards may be authorized and
unissued shares, shares of Common Stock held in the treasury of the Company, shares of Common Stock purchased on the open market
or by private purchase or a combination of the foregoing.

 

(e)           
Substitute Awards. Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption
of, or in substitution for, outstanding awards previously granted by an entity directly or indirectly acquired by the Company or
with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the Plan
Share Reserve; provided, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding
options intended to qualify as “incentive stock options” within the meaning of Section 422 of the Code shall be counted
against the aggregate number of shares of Common Stock available for Awards of Incentive Stock Options under the Plan. Subject
to applicable stock exchange requirements, available shares under a stockholder-approved plan of an entity directly or indirectly
acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination
transaction) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock available for issuance
under the Plan.

 

7.            
Options.

 

(a)            General.
Each Option granted under the Plan shall be evidenced by an Award Agreement, which agreement need not be the same for each
Participant. Each Option so granted shall be subject to the conditions set forth in this Section 7, and to such other
conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted under
the Plan shall be Nonqualified Stock Options unless the applicable Award Agreement expressly states that the Option is
intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees
of a member of the Company Group, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to
receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has
been approved by the stockholders of the Company in a manner intended to comply with the stockholder approval requirements of
Section 422(b)(1) of the Code; provided, that any Option intended to be an Incentive Stock Option shall not fail to be
effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified
Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions
of such grant shall be subject to, and comply with, such rules as may be prescribed by Section 422 of the Code. If for any
reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an Incentive Stock
Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified
Stock Option appropriately granted under the Plan.

 

     

    12

    

 

(b)           
Exercise Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise
price (“Exercise Price”) per share of Common Stock for each Option shall not be less than 100% of the Grant
Date Fair Market Value of such share; provided, however, that in the case of an Incentive Stock Option granted to an employee
who, at the time of the grant of such Option, owns stock representing more than 10% of the voting power of all classes of stock
of any member of the Company Group, the Exercise Price per share shall be no less than 110% of the Grant Date Fair Market Value
per share.

 

(c)           
Vesting and Expiration; Termination.

 

(i)               
Options shall vest and become exercisable in such manner and on such date or dates or upon such event or events as
determined by the Committee, including, without limitation, satisfaction of Performance Conditions; provided, however, that
notwithstanding any such vesting dates or events, the Committee may in its sole discretion accelerate the vesting of any Options
at any time and for any reason.

 

(ii)              
Options shall expire upon a date determined by the Committee, not to exceed 10 years from the Date of Grant (the
 “Option Period”); provided, that if the Option Period (other than in the case of an Incentive Stock Option)
would expire on a date when trading in the shares of Common Stock is prohibited by the Company’s insider trading policy (or
Company-imposed “blackout period”) and the Fair Market Value of the Common Stock exceeds the per-share Exercise Price
of the Options on the date of expiration, then the Option Period shall be automatically extended until the 30th day
following the expiration of such prohibition. Notwithstanding the foregoing, in no event shall the Option Period exceed five years
from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns stock representing
more than 10% of the voting power of all classes of stock of any member of the Company Group.

 

(iii)              Unless
otherwise provided by the Committee, whether in an Award Agreement or otherwise, in the event of: (A) a Participant’s
Termination by the Service Recipient for Cause, all outstanding Options granted to such Participant shall immediately
terminate and expire; (B) a Participant’s Termination due to death or Disability, each outstanding unvested Option
granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain
exercisable for one year thereafter (but in no event beyond the expiration of the Option Period); and (C) a
Participant’s Termination for any other reason, each outstanding unvested Option granted to such Participant shall
immediately terminate and expire, and each outstanding vested Option shall remain exercisable for 90 days thereafter (but in
no event beyond the expiration of the Option Period).

 

     

    13

    

 

(d)           
Method of Exercise and Form of Payment. No shares of Common Stock shall be issued pursuant to any exercise
of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the
Company an amount equal to any Federal, state, local and non-U.S. income, employment and any other applicable taxes that are statutorily
required to be withheld as determined in accordance with Section 13(d) hereof. Options which have become exercisable may be exercised
by delivery of written or electronic notice of exercise to the Company (or telephonic instructions to the extent provided by the
Committee) in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be
payable: (i) in cash, check, cash equivalent and/or shares of Common Stock valued at the Fair Market Value at the time the Option
is exercised (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient
number of shares of Common Stock in lieu of actual issuance of such shares to the Company); provided, that such shares of
Common Stock are not subject to any pledge or other security interest and have been held by the Participant for at least six months
(or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment applying
generally accepted accounting principles (“GAAP”)); or (ii) by such other method as the Committee may permit,
in its sole discretion, including, without limitation (A) in other property having a fair market value on the date of exercise
equal to the Exercise Price; (B) if there is a public market for the shares of Common Stock at such time, by means of a broker-assisted
 “cashless exercise” pursuant to which the Company is delivered (including telephonically to the extent permitted by
the Committee) a copy of irrevocable instructions to a stockbroker to sell the shares of Common Stock otherwise issuable upon the
exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price; or (C) a “net exercise”
procedure effected by withholding the minimum number of shares of Common Stock otherwise issuable in respect of an Option that
are needed to pay the Exercise Price and any Federal, state, local and non-U.S. income, employment and any other applicable taxes
that are statutorily required to be withheld as determined in accordance with Section 13(d) hereof. Unless otherwise determined
by the Committee, any fractional shares of Common Stock shall be settled in cash.

 

(e)           
Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive
Stock Option under the Plan shall notify the Company in writing immediately after the date the Participant makes a disqualifying
disposition of any shares of Common Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition
is any disposition (including, without limitation, any sale) of such shares of Common Stock before the later of (i) the date that
is two years after the Date of Grant of the Incentive Stock Option or (ii) the date that is one year after the date of exercise
of the Incentive Stock Option. The Company may, if determined by the Committee and in accordance with procedures established by
the Committee, retain possession, as agent for the applicable Participant, of any shares of Common Stock acquired pursuant to the
exercise of an Incentive Stock Option until the end of the period described in the preceding sentence, subject to complying with
any instructions from such Participant as to the sale of such shares of Common Stock.

 

     

    14

    

 

(f)            Compliance With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to
exercise an Option in a manner which the Committee determines would violate the Sarbanes-Oxley Act of 2002, as it may be amended
from time to time, or any other Applicable Law.

 

8.             Restricted
Stock and Restricted Stock Units.

 

(a)            General.
Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award Agreement. Each Restricted Stock and
Restricted Stock Unit so granted shall be subject to the conditions set forth in this Section 8, and to such other conditions
not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

 

(b)           Stock
Certificates and Book-Entry; Escrow or Similar Arrangement. Upon the grant of Restricted Stock, the Committee shall cause
a stock certificate registered in the name of the Participant to be issued or shall cause share(s) of Common Stock to be registered
in the name of the Participant and held in book-entry form subject to the Company’s directions and, if the Committee determines
that the Restricted Stock shall be held by the Company or in escrow rather than issued to the Participant pending the release
of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i)
an escrow agreement satisfactory to the Committee, if applicable and (ii) the appropriate stock power (endorsed in blank) with
respect to the Restricted Stock covered by such agreement. Subject to the restrictions set forth in this Section 8, Section 13(b)
of the Plan and the applicable Award Agreement, a Participant generally shall have the rights and privileges of a stockholder
as to shares of Restricted Stock, including, without limitation, the right to vote such Restricted Stock. To the extent shares
of Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to
the Company, and all rights of the Participant to such shares and as a stockholder with respect thereto shall terminate without
further obligation on the part of the Company. A Participant shall have no rights or privileges as a stockholder as to Restricted
Stock Units.

 

(c)            Vesting;
Termination.

 

(i)               
Restricted Stock and Restricted Stock Units shall vest, and any applicable Restricted Period shall lapse, in such
manner and on such date or dates or upon such event or events as determined by the Committee, including, without limitation, satisfaction
of Performance Conditions; provided, however, that, notwithstanding any such dates or events, the Committee may, in its
sole discretion, accelerate the vesting of any Restricted Stock or Restricted Stock Unit or the lapsing of any applicable Restricted
Period at any time and for any reason.

 

(ii)              
Unless otherwise provided by the Committee, whether in an Award Agreement or otherwise,
in the event of a Participant’s Termination for any reason prior to the time that such Participant’s Restricted Stock
or Restricted Stock Units, as applicable, have vested, (A) all vesting with respect to such Participant’s Restricted Stock
or Restricted Stock Units, as applicable, shall cease and (B) unvested shares of Restricted Stock and unvested Restricted Stock
Units, as applicable, shall be forfeited to the Company by the Participant for no consideration as of the date of such Termination.

 

     

    15

    

 

(d)          
 Issuance of Restricted Stock and Settlement of Restricted Stock Units.

 

(i)               
Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set
forth in the applicable Award Agreement shall be of no further force or effect with respect to such shares, except as set forth
in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration, the Company shall issue to the Participant,
or the Participant’s beneficiary, without charge, the stock certificate (or, if applicable, a notice evidencing a book-entry
notation) evidencing the shares of Restricted Stock which have not then been forfeited and with respect to which the Restricted
Period has expired (rounded down to the nearest full share).

 

(ii)              
Unless otherwise provided by the Committee in an Award Agreement or otherwise, upon the expiration of the Restricted
Period with respect to any outstanding Restricted Stock Units, the Company shall issue to the Participant or the Participant’s
beneficiary, without charge, one share of Common Stock (or other securities or other property, as applicable) for each such outstanding
Restricted Stock Unit; provided, however, that the Committee may, in its sole discretion, elect to (A) pay cash or part
cash and part shares of Common Stock in lieu of issuing only shares of Common Stock in respect of such Restricted Stock Units;
or (B) defer the issuance of shares of Common Stock (or cash or part cash and part shares of Common Stock, as the case may be)
beyond the expiration of the Restricted Period if such extension would not cause adverse tax consequences under Section 409A of
the Code. If a cash payment is made in lieu of issuing shares of Common Stock in respect of such Restricted Stock Units, the amount
of such payment shall be equal to the Fair Market Value per share of the Common Stock as of the date on which the Restricted Period
lapsed with respect to such Restricted Stock Units.

 

(e)           
Legends on Restricted Stock. Each certificate, if any, or book entry representing Restricted Stock awarded
under the Plan, if any, shall bear a legend or book entry notation substantially in the form of the following, in addition to any
other information the Company deems appropriate, until the lapse of all restrictions with respect to such shares of Common Stock:

 

TRANSFER
OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE Certara, Inc. 2020 INCENTIVE PLAN
AND A RESTRICTED STOCK AWARD AGREEMENT BETWEEN Certara, Inc. AND THE PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON
FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF Certara, Inc.

 

     

    16

    

 

9.            
Other Equity-Based Awards. The Committee may grant Other Equity-Based Awards under
the Plan to Eligible Persons, alone or in tandem with other Awards, in such amounts and dependent on such conditions as the Committee
shall from time to time in its sole discretion determine, including, without limitation, satisfaction of Performance Conditions.
Each Other Equity-Based Award granted under the Plan shall be evidenced by an Award Agreement
and shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

 

10.           Cash-Based
Incentive Awards. The Committee may grant Cash-Based Incentive Awards under the Plan to any
Eligible Person, in such amounts and dependent on such conditions as the Committee shall from time to time in its sole discretion
determine, including, without limitation, satisfaction of Performance Conditions. Each Cash-Based Incentive Award granted under
the Plan shall be evidenced in such form as the Committee may determine from time to time.

 

11.           Changes
in Capital Structure and Similar Events. Notwithstanding any other provision in the Plan to
the contrary, the following provisions shall apply to all Awards granted hereunder (other than Cash-Based Incentive Awards):

 

(a)            General. In the event of (i) any dividend (other than regular cash dividends) or other distribution (whether
in the form of cash, shares of Common Stock, other securities or other property), recapitalization, stock split, reverse stock
split, reorganization, merger, consolidation, split-up, split-off, spin-off, combination, repurchase or exchange of shares of Common
Stock or other securities of the Company, issuance of warrants or other rights to acquire shares of Common Stock or other securities
of the Company, or other similar corporate transaction or event that affects the shares of Common Stock (including a Change in
Control); or (ii) unusual or nonrecurring events affecting the Company, including changes in applicable rules, rulings, regulations
or other requirements, that the Committee determines, in its sole discretion, could result in substantial dilution or enlargement
of the rights intended to be granted to, or available for, Participants (any event in (i) or (ii), an “Adjustment Event”),
the Committee shall, in respect of any such Adjustment Event, make such proportionate substitution or adjustment, if any, as it
deems equitable, to any or all of (A) the Plan Share Reserve, or any other limit applicable under the Plan with respect to the
number of Awards which may be granted hereunder; (B) the number of shares of Common Stock or other securities of the Company (or
number and kind of other securities or other property) which may be issued in respect of Awards or with respect to which Awards
may be granted under the Plan or any Sub-Plan; and (C) the terms of any outstanding Award, including, without limitation, (I) the
number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property)
subject to outstanding Awards or to which outstanding Awards relate; (II) the Exercise Price or SAR Base Price with respect to
any Option or SAR, as applicable, or any amount payable as a condition of issuance of shares of Common Stock (in the case of any
other Award); or (III) any applicable performance measures; provided, that in the case of any “equity restructuring”
(within the meaning of the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor pronouncement
thereto)), the Committee shall make an equitable or proportionate adjustment to outstanding Awards to reflect such equity restructuring.

 

     

    17

    

 

(b)           Change
in Control. Without limiting the foregoing, in connection with any Adjustment Event that is a Change in Control, the Committee
may, in its sole discretion, provide for any one or more of the following:

 

(i)              
 substitution or assumption of, acceleration of the vesting of, exercisability of, or lapse of restrictions on, any
one or more outstanding Awards; and

 

(ii)              
cancellation of any one or more outstanding Awards and payment to the holders of such Awards that are vested as of
such cancellation (including, without limitation, any Awards that would vest as a result of the occurrence of such event but for
such cancellation or for which vesting is accelerated by the Committee in connection with such event pursuant to clause (i) above),
the value of such Awards, if any, as determined by the Committee (which value, if applicable, may be based upon the price per share
of Common Stock received or to be received by other stockholders of the Company in such event), including, without limitation,
in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value
(as of a date specified by the Committee) of the shares of Common Stock subject to such Option or SAR over the aggregate Exercise
Price or SAR Base Price of such Option or SAR (it being understood that, in such event, any Option or SAR having a per share Exercise
Price or SAR Base Price equal to, or in excess of, the Fair Market Value of a share of Common Stock subject thereto may be canceled
and terminated without any payment or consideration therefor).

 

For purposes
of clause (i) above, an award will be considered granted in substitution of an Award if it has an equivalent value (as determined
consistent with clause (ii) above) with the original Award, whether designated in securities of the acquiror in such Change in
Control transaction (or an Affiliate thereof), or in cash or other property (including in the same consideration that other stockholders
of the Company receive in connection with such Change in Control transaction), and retains the vesting schedule applicable to the
original Award.

 

Payments
to holders pursuant to clause (ii) above shall be made in cash or, in the sole discretion of the Committee, in the form of such
other consideration necessary for a Participant to receive property, cash, or securities (or combination thereof) as such Participant
would have been entitled to receive upon the occurrence of the transaction if the Participant had been, immediately prior to such
transaction, the holder of the number of shares of Common Stock covered by the Award at such time (less any applicable Exercise
Price or SAR Base Price).

 

(c)           
Other Requirements. Prior to any payment or adjustment contemplated under this Section 11, the Committee may
require a Participant to (i) represent and warrant as to the unencumbered title to the Participant’s Awards; (ii) bear such
Participant’s pro rata share of any post-closing indemnity obligations, and be subject to the same post-closing purchase
price adjustments, escrow terms, offset rights, holdback terms, and similar conditions as the other holders of Common Stock, subject
to any limitations or reductions as may be necessary to comply with Section 409A of the Code; and (iii) deliver customary transfer
documentation as reasonably determined by the Committee.

 

(d)          
Fractional Shares. Any adjustment provided under this Section 11 may provide for the elimination of any fractional
share that might otherwise become subject to an Award.

 

     

    18

    

 

(e)           
Binding Effect. Any adjustment, substitution, determination of value or other action taken by the Committee
under this Section 11 shall be conclusive and binding for all purposes.

 

12.          
Amendments and Termination.

 

(a)           
Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate the
Plan or any portion thereof at any time; provided, that no such amendment, alteration, suspension, discontinuance or termination
shall be made without stockholder approval if (i) such approval is required under Applicable Law; (ii) it would materially
increase the number of securities which may be issued under the Plan (except for increases pursuant to Section 6 or 11 of the Plan);
or (iii) it would materially modify the requirements for participation in the Plan; provided, further, that any such amendment,
alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant
or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the
affected Participant, holder or beneficiary. Notwithstanding the foregoing, no amendment shall be made to Section 12(c) of the
Plan without stockholder approval.

 

(b)          
Amendment of Award Agreements. The Committee may, to the extent consistent with the terms of the Plan and
any applicable Award Agreement, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel
or terminate, any Award theretofore granted or the associated Award Agreement, prospectively or retroactively (including after
a Participant’s Termination); provided, that, other than pursuant to Section 11, any such waiver, amendment, alteration,
suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant
with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant.

 

(c)           
No Repricing. Notwithstanding anything in the Plan to the contrary, without stockholder approval, except as
otherwise permitted under Section 11 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option
or the SAR Base Price of any SAR; (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option
or SAR (with a lower Exercise Price or SAR Base Price, as the case may be) or other Award or cash payment that is greater than
the intrinsic value (if any) of the cancelled Option or SAR; and (iii) the Committee may not take any other action which is considered
a “repricing” for purposes of the stockholder approval rules of any securities exchange or inter-dealer quotation system
on which the securities of the Company are listed or quoted.

 

13.          
General. 

 

(a)            Award
Agreements. Each Award (other than a Cash-Based Incentive Award) under the Plan shall be evidenced by an Award Agreement,
which shall be delivered to the Participant to whom such Award was granted and shall specify the terms and conditions of the
Award and any rules applicable thereto, including, without limitation, the effect on such Award of the death, Disability or
Termination of a Participant, or of such other events as may be determined by the Committee. For purposes of the Plan, an
Award Agreement may be in any such form (written or electronic) as determined by the Committee (including, without
limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate or a letter) evidencing the
Award. The Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative
of the Company.

 

     

    19

    

 

(b)          
Nontransferability.

 

(i)               
Each Award shall be exercisable only by such Participant to whom such Award was granted during the Participant’s
lifetime, or, if permissible under Applicable Law, by the Participant’s legal guardian or representative. No Award may be
assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant (unless such transfer is specifically
required pursuant to a domestic relations order or by Applicable Law) other than by will or by the laws of descent and distribution
and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable
against any member of the Company Group; provided, that the designation of a beneficiary shall not constitute an assignment,
alienation, pledge, attachment, sale, transfer or encumbrance.

 

(ii)              
Notwithstanding the foregoing, the Committee may (after giving due consideration to any applicable non-U.S. laws),
in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without consideration,
subject to such rules as the Committee may adopt consistent with any applicable Award Agreement to preserve the purposes of the
Plan, to (A) any person who is a “family member” of the Participant, as such term is used in the instructions to Form
S-8 under the Securities Act or any successor form of registration statement promulgated by the Securities and Exchange Commission
(collectively, the “Immediate Family Members”); (B) a trust solely for the benefit of the Participant and the
Participant’s Immediate Family Members; (C) a partnership or limited liability company whose only partners or stockholders
are the Participant and the Participant’s Immediate Family Members; or (D) a beneficiary to whom donations are eligible to
be treated as “charitable contributions” for federal income tax purposes (each transferee described in clauses (A),
(B), (C) and (D) above is hereinafter referred to as a “Permitted Transferee”); provided, that the Participant
gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies
the Participant in writing that such a transfer would comply with the requirements of the Plan.

 

(iii)              The
terms of any Award transferred in accordance with clause (ii) above shall apply to the Permitted Transferee and any reference
in the Plan, or in any applicable Award Agreement, to a Participant shall be deemed to refer to the Permitted Transferee,
except that (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent
and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in
effect a registration statement on an appropriate form covering the shares of Common Stock to be acquired pursuant to the
exercise of such Option if the Committee determines, consistent with any applicable Award Agreement, that such a registration
statement is necessary or appropriate; (C) neither the Committee nor the Company shall be required to provide any notice to a
Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant
under the Plan or otherwise; and (D) the consequences of a Participant’s Termination under the terms of the Plan and
the applicable Award Agreement shall continue to be applied with respect to the Participant, including, without limitation,
that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the
Plan and the applicable Award Agreement.

(c)           
Dividends and Dividend Equivalents.

 

(i)                The
Committee may, in its sole discretion, provide a Participant as part of an Award with dividends, dividend equivalents, or similar
payments in respect of Awards, payable in cash, shares of Common Stock, other securities, other Awards or other property, on a
current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole discretion, including,
without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the
Award or reinvestment in additional shares of Common Stock, Restricted Stock or other Awards.

 

(ii)              
Without limiting the foregoing, unless otherwise provided in the Award Agreement, any dividend otherwise payable
in respect of any share of Restricted Stock that remains subject to vesting conditions at the time of payment of such dividend
shall be retained by the Company and remain subject to the same vesting conditions as the share of Restricted Stock to which the
dividend relates and shall be delivered (without interest) to the Participant within 15 days following the date on which such restrictions
on such Restricted Stock lapse (and the right to any such accumulated dividends shall be forfeited upon the forfeiture of the Restricted
Stock to which such dividends relate).

 

(iii)             
To the extent provided in an Award Agreement, the holder of outstanding Restricted Stock Units shall be entitled
to be credited with dividend equivalent payments (upon the payment by the Company of dividends on shares of Common Stock) either
in cash or, in the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of
such dividends (and interest may, in the sole discretion of the Committee, be credited on the amount of cash dividend equivalents
at a rate and subject to such terms as determined by the Committee), which accumulated dividend equivalents (and interest thereon,
if applicable) shall be payable at the same time as the underlying Restricted Stock Units are settled following the date on which
the Restricted Period lapses with respect to such Restricted Stock Units, and if such Restricted Stock Units are forfeited, the
Participant shall have no right to such dividend equivalent payments (or interest thereon, if applicable).

 

(d)          
Tax Withholding.

 

(i)                 A
Participant shall be required to pay to the Company or one or more of its Subsidiaries, as applicable, an amount in cash (by
check or wire transfer) equal to the aggregate amount of any income, employment and/or other applicable taxes that are
statutorily required to be withheld in respect of an Award. Alternatively, the Company or any of its Subsidiaries may elect,
in its sole discretion, to satisfy this requirement by withholding such amount from any cash compensation or other cash
amounts owing to a Participant.

 

     

    21

    

 

(ii)              
Without limiting the foregoing, the Committee may (but is not obligated to), in its sole discretion, permit or require
a Participant to satisfy, all or any portion of the minimum income, employment and/or other applicable taxes that are statutorily
required to be withheld with respect to an Award by (A) the delivery of shares of Common Stock (which are not subject to any pledge
or other security interest) that have been both held by the Participant and vested for at least six months (or such other period
as established from time to time by the Committee in order to avoid adverse accounting treatment under applicable accounting standards)
having an aggregate Fair Market Value equal to such minimum statutorily required withholding liability (or portion thereof); or
(B) having the Company withhold from the shares of Common Stock otherwise issuable or deliverable to, or that would otherwise be
retained by, the Participant upon the grant, exercise, vesting or settlement of the Award, as applicable, a number of shares of
Common Stock with an aggregate Fair Market Value equal to an amount, subject to clause (iii) below, not in excess of such minimum
statutorily required withholding liability (or portion thereof).

 

(iii)            
 The Committee, subject to its having considered the applicable accounting impact of any such determination, has
full discretion to allow Participants to satisfy, in whole or in part, any additional income, employment and/or other applicable
taxes payable by them with respect to an Award by electing to have the Company withhold from the shares of Common Stock otherwise
issuable or deliverable to, or that would otherwise be retained by, a Participant upon the grant, exercise, vesting or settlement
of the Award, as applicable, shares of Common Stock having an aggregate Fair Market Value that is greater than the applicable minimum
required statutory withholding liability (but such withholding may in no event be in excess of the maximum statutory withholding
amount(s) in a Participant’s relevant tax jurisdictions).

 

(e)            No
Claim to Awards; No Rights to Continued Employment; Waiver. No employee of any member of the Company Group, or other
Person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an
Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or
holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and
interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among
Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall
be construed as giving any Participant any right to be retained in the employ or service of the Service Recipient or any
other member of the Company Group, nor shall it be construed as giving any Participant any rights to continued service on the
Board. The Service Recipient or any other member of the Company Group may at any time dismiss a Participant from employment
or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly
provided in the Plan or any Award Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to
have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to
non-continuation of the Award beyond the period provided under the Plan or any Award Agreement, except to the extent of any
provision to the contrary in any written employment contract or other agreement between the Service Recipient and/or any
member of the Company Group and the Participant, whether any such agreement is executed before, on or after the Date of
Grant.

 

     

    22

    

 

(f)           
International Participants. With respect to Participants who reside or work outside of the United States of
America, the Committee may, in its sole discretion, amend the terms of the Plan and create or amend Sub-Plans or amend outstanding
Awards with respect to such Participants in order to permit or facilitate participation in the Plan by such Participants, conform
such terms with the requirements of Applicable Law or to obtain more favorable tax or other treatment for a Participant or any
member of the Company Group.

 

(g)           
Designation and Change of Beneficiary. To the extent allowed under Applicable Law and permitted by the Company,
each Participant may file with the Committee a written designation of one or more Persons as the beneficiary(ies) who shall be
entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon the Participant’s death.
However, the Company may prohibit designation of a beneficiary at any time and for any reason, including due to any conclusion
by the Company that such designation would be inconsistent with the provisions of Applicable Law. A Participant may, from time
to time, revoke or change the Participant’s beneficiary designation without the consent of any prior beneficiary by filing
a new designation with the Committee. The last such designation received by the Committee shall be controlling; provided, however,
that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant’s
death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant
or in the event the Company determines that any such designation does not comply with Applicable Law, the beneficiary shall be
deemed to be the Participant’s estate.

 

(h)          
Termination. Except as otherwise provided in an Award Agreement, unless determined otherwise by the Committee
at any point following such event: (i) neither a temporary absence from employment or service due to illness, vacation or leave
of absence (including, without limitation, a call to active duty for military service through a Reserve or National Guard unit)
nor a transfer from employment or service with one Service Recipient to employment or service with another Service Recipient (or
vice-versa) shall be considered a Termination; and (ii) if a Participant undergoes a Termination, but such Participant continues
to provide services to the Company Group in a non-employee capacity, such change in status shall not be considered a Termination
for purposes of the Plan. Further, unless otherwise determined by the Committee, in the event that any Service Recipient ceases
to be a member of the Company Group (by reason of sale, divestiture, spin-off or other similar transaction), unless a Participant’s
employment or service is transferred to another entity that would constitute a Service Recipient immediately following such transaction,
such Participant shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such transaction.

 

(i)            
No Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award Agreement,
no Person shall be entitled to the privileges of ownership in respect of shares of Common Stock which are subject to Awards hereunder
until such shares have been issued or delivered to such Person.

 

     

    23

    

 

(j)           
  Government and Other Regulations.

 

(i)                The
obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to all Applicable
Law. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to
sell or to sell, and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless
such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission
or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company,
that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and
conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under
the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have the authority
to provide that all shares of Common Stock or other securities of any member of the Company Group issued under the Plan shall
be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable
Award Agreement and Applicable Law, and, without limiting the generality of Section 8 of the Plan, the Committee may cause a legend
or legends to be put on certificates representing shares of Common Stock or other securities of any member of the Company Group
issued under the Plan to make appropriate reference to such restrictions or may cause such Common Stock or other securities of
any member of the Company Group issued under the Plan in book-entry form to be held subject to the Company’s instructions
or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves
the right to add, at any time, any additional terms or provisions to any Award granted under the Plan that the Committee, in its
sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any governmental
entity to whose jurisdiction the Award is subject.

 

(ii)               The
Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual
restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of shares of
Common Stock from the public markets, the Company’s issuance of Common Stock to the Participant, the
Participant’s acquisition of Common Stock from the Company and/or the Participant’s sale of Common Stock to the
public markets, illegal, impracticable or inadvisable. If the Committee determines to cancel all or any portion of an Award
in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply
with Section 409A of the Code, (A) in the case of Options, SARs or other Awards subject to exercise, pay to the Participant
an amount equal to the excess of (I) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or
portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested
or issued, as applicable); over (II) the aggregate Exercise Price or SAR Base Price (in the case of an Option or SAR,
respectively) or any amount payable as a condition of issuance of shares of Common Stock (in the case of any other Award
subject to exercise), or (B) in the case of Restricted Stock, Restricted Stock Units or Other Equity-Based Awards, provide
the Participant with a cash payment or equity subject to deferred vesting and delivery consistent with the vesting
restrictions applicable to such Restricted Stock, Restricted Stock Units or Other Equity-Based Awards, or the underlying
shares in respect thereof. Any applicable amounts shall be delivered to the Participant as soon as practicable following the
cancellation of such Award or portion thereof.

 

     

    24

    

 

(k)           
No Section 83(b) Elections Without Consent of Company. No election under Section 83(b) of the Code or under
a similar provision of law may be made unless expressly permitted by the terms of the applicable Award Agreement or by action of
the Committee in writing prior to the making of such election. If a Participant, in connection with the acquisition of shares of
Common Stock under the Plan or otherwise, is expressly permitted to make such election and the Participant makes the election,
the Participant shall notify the Company of such election within 10 days after filing notice of the election with the Internal
Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to Section 83(b)
of the Code or other applicable provision.

 

(l)            
Payments to Persons Other Than Participants. If the Committee shall find that any Person to whom any amount
is payable under the Plan is unable to care for the Participant’s affairs because of illness or accident, or is a minor,
or has died, then any payment due to such Person or the Participant’s estate (unless a prior claim therefor has been made
by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to the Participant’s spouse,
child, relative, an institution maintaining or having custody of such Person, or any other Person deemed by the Committee to be
a proper recipient on behalf of such Person otherwise entitled to payment. Any such payment shall be a complete discharge of the
liability of the Committee and the Company therefor.

 

(m)          
Nonexclusivity of the Plan. Neither the adoption of the Plan by the Board nor the submission of the Plan to
the stockholders of the Company for approval shall be construed 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 equity-based awards
otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

 

(n)           
No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or
separate fund of any kind or a fiduciary relationship between any member of the Company Group, on the one hand, and a Participant
or other Person, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying
any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made
or otherwise to segregate any assets, nor shall the Company be obligated to maintain separate bank accounts, books, records or
other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall
have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as they may have become
entitled to payment of additional compensation by performance of services, they shall have the same rights as other service providers
under general law.

 

     

    25

    

 

(o)           Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in
acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance
upon any report made by the independent public accountant of any member of the Company Group and/or any other information furnished
in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself or herself.

 

(p)          
Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits
under any pension, retirement, profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically
provided in such other plan or as required by Applicable Law.

 

(q)          
Governing Law. The Plan shall be governed by and construed in accordance with the internal laws of the State
of Delaware applicable to contracts made and performed wholly within the State of Delaware, without giving effect to the conflict
of laws provisions thereof. EACH PARTICIPANT WHO ACCEPTS AN AWARD IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY SUIT,
ACTION, OR OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PARTICIPANT IN RESPECT OF THE PARTICIPANT’S RIGHTS OR OBLIGATIONS
HEREUNDER.

 

(r)           
Severability. If any provision of the Plan or any Award or Award Agreement 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 construed or deemed 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.

 

(s)           
Obligations Binding on Successors. The obligations of the Company under the Plan shall be binding upon any
successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon
any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

 

(t)           
Section 409A of the Code.

 

(i)                 Notwithstanding
any provision of the Plan to the contrary, it is intended that the provisions of the Plan comply with Section 409A of the
Code, and all provisions of the Plan shall be construed and interpreted in a manner consistent with the requirements for
avoiding taxes or penalties under Section 409A of the Code. Each Participant is solely responsible and liable for the
satisfaction of all taxes and penalties that may be imposed on or in respect of such Participant in connection with the Plan
(including any taxes and penalties under Section 409A of the Code), and neither the Service Recipient nor any other member of
the Company Group shall have any obligation to indemnify or otherwise hold such Participant (or any beneficiary) harmless
from any or all of such taxes or penalties. With respect to any Award that is considered “deferred compensation”
subject to Section 409A of the Code, references in the Plan to “termination of employment” (and substantially
similar phrases) shall mean “separation from service” within the meaning of Section 409A of the Code. For
purposes of Section 409A of the Code, each of the payments that may be made in respect of any Award granted under the Plan is
designated as separate payments.

 

     

    26

    

 

(ii)              
Notwithstanding anything in the Plan to the contrary, if a Participant is a “specified employee” within
the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments in respect of any Awards that are “deferred compensation”
subject to Section 409A of the Code and which would otherwise be payable upon the Participant’s “separation from service”
(as defined in Section 409A of the Code) shall be made to such Participant prior to the date that is six months after the date
of such Participant’s “separation from service” or, if earlier, the date of the Participant’s death. Following
any applicable six month delay, all such delayed payments will be paid in a single lump sum on the earliest date permitted under
Section 409A of the Code that is also a business day.

 

(iii)             
Unless otherwise provided by the Committee in an Award Agreement or otherwise, in the event that the timing of payments
in respect of any Award (that would otherwise be considered “deferred compensation” subject to Section 409A of the
Code) would be accelerated upon the occurrence of (A) a Change in Control, no such acceleration shall be permitted unless the event
giving rise to the Change in Control satisfies the definition of a change in the ownership or effective control of a corporation,
or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section 409A of the Code; or (B)
a Disability, no such acceleration shall be permitted unless the Disability also satisfies the definition of “Disability”
pursuant to Section 409A of the Code.

 

(u)           Clawback/Repayment. All Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the
extent necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or the Committee and
as in effect from time to time; and (ii) Applicable Law. Further, unless otherwise determined by the Committee, to the extent that
the Participant receives any amount in excess of the amount that the Participant should otherwise have received under the terms
of the Award for any reason (including, without limitation, by reason of a financial restatement, mistake in calculations or other
administrative error), the Participant shall be required to repay any such excess amount to the Company.

 

(v)           Detrimental
Activity. Notwithstanding anything to the contrary contained herein, if a Participant has engaged in any Detrimental Activity,
as determined by the Committee, the Committee may, in its sole discretion, provide for one or more of the following:

 

(i)                
cancellation of any or all of such Participant’s outstanding Awards; or

 

(ii)               
forfeiture by the Participant of any gain realized in respect of Awards, and repayment of any such gain promptly
to the Company.

 

     

    27

    

 

(w)           Right
of Offset. The Company will have the right to offset against its obligation to deliver shares of Common Stock (or other
property or cash) under the Plan or any Award Agreement any outstanding amounts (including, without limitation, travel and
entertainment or advance account balances, loans, repayment obligations under any Awards, or amounts repayable to the Company
pursuant to tax equalization, housing, automobile or other employee programs) that the Participant then owes to any member of
the Company Group and any amounts the Committee otherwise deems appropriate pursuant to any tax equalization policy or
agreement. Notwithstanding the foregoing, if an Award is “deferred compensation” subject to Section 409A of the
Code, the Committee will have no right to offset against its obligation to deliver shares of Common Stock (or other property
or cash) under the Plan or any Award Agreement if such offset could subject the Participant to the additional tax imposed
under Section 409A of the Code in respect of an outstanding Award.

 

(x)            
Expenses; Titles and Headings. The expenses of administering the Plan shall be borne by the Company Group.
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.Exhibit 10.21

 

CERTARA, INC.

2020 EMPLOYEE STOCK PURCHASE PLAN

 

1.                 
Purpose. The purpose of the Plan is to provide a means by which Eligible Employees may purchase Common Stock, thereby
strengthening their commitment to the welfare of the Company and its Designated Companies and aligning their interests with those
of the Company’s stockholders. The Company intends for offerings under the Plan to qualify as an “employee stock purchase
plan” under Section 423 of the Code (each, a “Section 423 Offering”); provided, however, that the Committee may
also authorize the grant of rights under offerings of the Plan that are not intended to comply with the requirements of Section
423 of the Code, pursuant to any rules, procedures, agreements, appendices, or sub-plans adopted by the Committee for such purpose
(each, a “Non-423 Offering”).

 

2.                 
Definitions. The following definitions shall be applicable throughout the Plan.

 

(a)              
“Affiliate” means any Person that directly or indirectly controls, is controlled by or is under common
control with the Company. The term “control” (including, with correlative meaning, the terms “controlled by”
and “under common control with”), as applied to any Person, means the possession, directly or indirectly, of the power
to direct or cause the direction of the management and policies of such Person, whether through the ownership of voting or other
securities, by contract or otherwise.

 

(b)              
 “Applicable Percentage” means, with respect to any Offering Period, [●]%; provided, however,
that prior to the Offering Commencement Date applicable to any such Offering Period, the Committee may determine a higher or lower
Applicable Percentage so long as such percentage remains eighty five percent (85%) or greater.

 

(c)              
“Base Compensation” means regular base straight-time gross earnings paid by the Company or any Subsidiary
or Affiliate to the Eligible Employee (other than amounts paid after termination of employment, even if such amounts are paid for
pre-termination date services) as base salary or wages (including 13th/14th month payments or similar concepts under local law),
excluding payments, if any, for overtime, incentive compensation, commissions, incentive payments, premiums, bonuses, and
any other special remuneration of a Participant during an Offering Period. Notwithstanding the foregoing, the Committee may, in
its discretion, on a uniform and nondiscriminatory basis, establish a different definition of “Base Compensation” for
a subsequent Offering Period prior to the Offering Commencement Date of such subsequent Offering Period. Further, the Committee
will have discretion to determine the application of this definition to Eligible Employees outside the United States.

 

(d)              
“Board” means the Board of Directors of the Company.

 

(e)              
“Change in Control” means:

 

(i)                 the

beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of more than 50% (on a fully
diluted basis) of either (A) the Outstanding Common Stock; or (B) the Outstanding Company Voting Securities; provided,
however, that for purposes of the Plan, the following acquisitions shall not constitute a Change in Control: (I) any
acquisition by the Company or any Affiliate; (II) any acquisition by any employee benefit plan sponsored or maintained by the
Company or any Affiliate; or (III) in respect of an Award held by a particular Participant, any acquisition by the
Participant or any group of Persons including the Participant (or any entity controlled by the Participant or any group of
Persons including the Participant);

 

     

    2

    

 

(ii)             
during any period of 24 months, individuals who, at the beginning of such period, constitute the Board (the “Incumbent
Directors”) cease for any reason to constitute at least a majority of the Board, provided that any person becoming a
director subsequent to the Effective Date, whose election or nomination for election was approved by a vote of at least two-thirds
of the Incumbent Directors then on the Board (either by a specific vote or by approval of the proxy statement of the Company in
which such person is named as a nominee for director, without written objection to such nomination) shall be an Incumbent Director;
provided, however, that no individual initially elected or nominated as a director of the Company as a result of an actual
or threatened election contest, as such terms are used in Rule 14a-12 of Regulation 14A promulgated under the Exchange Act, with
respect to directors or as a result of any other actual or threatened solicitation of proxies or consents by or on behalf of any
person other than the Board shall be deemed to be an Incumbent Director;

 

(iii)           
the consummation of a reorganization, recapitalization, merger, consolidation, or similar corporate transaction involving
the Company that requires the approval of the Company’s stockholders (a “Business Combination”), unless
immediately following such Business Combination: more than 50% of the total voting power of (A) the entity resulting from such
Business Combination (the “Surviving Company”), or (B) if applicable, the ultimate parent entity that directly
or indirectly has beneficial ownership of sufficient voting securities eligible to elect a majority of the board of directors (or
the analogous governing body) of the Surviving Company, is represented by the Outstanding Company Voting Securities that were outstanding
immediately prior to such Business Combination (or, if applicable, is represented by shares into which the Outstanding Company
Voting Securities were converted pursuant to such Business Combination); or

 

(iv)            
the sale, transfer or other disposition of all or substantially all of the assets of the Company Group (taken as a whole)
to any Person that is not an Affiliate of the Company.

 

For the avoidance of doubt, a registered public
offering of the Common Stock will not constitute a Change in Control.

 

(f)               
“Code” means the U.S. Internal Revenue Code of 1986, as amended, and any successor thereto. Reference
in the Plan to any section of the Code shall be deemed to include any regulations or other interpretative guidance under such section,
and any amendments or successor provisions to such section, regulations or guidance.

 

     

    3

    

 

(g)

or, if no such Compensation Committee or subcommittee thereof exists, the Board.

 

(h)              
“Common Stock” means the common stock of the Company, par value $0.01 per share (and any stock or other
securities into which such Common Stock may be converted or into which it may be exchanged).

 

(i)                
“Company” means Certara, Inc., a Delaware corporation, and any successor thereto.

 

(j)                
“Company Group” means, collectively, the Company and its Subsidiaries.

 

(k)              
“Designated Company” means any Subsidiary or Affiliate, whether now existing or existing in the future,
that has been designated by the Committee from time to time in its sole discretion as eligible to participate in the Plan. The
Committee may designate any Subsidiary or Affiliate as a Designated Company in a Non-423 Offering. For purposes of a Section 423
Offering, only the Company and any Subsidiary may be Designated Companies; provided, however, that at any given time, a Subsidiary
that is a Designated Company under a Section 423 Offering will not be a Designated Company under a Non-423 Offering.

 

(l)                
“Effective Date” means the date the Plan is approved by the Board, subject to stockholder approval as
provided in Section 11(d) hereof.

 

(m)            
“Eligible Employees” means, subject to the limitations set forth in Section 4(b) hereof, any individual
employed by the Company or a Designated Company except (i) employees who are not employed by the Company or a Designated Company
prior to the beginning of an Offering Period or prior to such other time period specified by the Committee; (ii) individuals who

3.                 
Shares of Common Stock.

 

(a)               
Shares of Common Stock Reserved For the Plan. Subject to adjustment upon changes in capitalization of the
Company as provided in Section 9(a) hereof, the maximum number of shares of Common Stock which may be issued under the Plan shall
be one million seven hundred thousand (1,700,000). Such shares of Common Stock may be authorized but unissued shares of Common Stock, treasury shares or shares of Common
Stock purchased in the open market. For avoidance of doubt, up to the maximum number of shares of Common Stock reserved under this
Section 3 may be used to satisfy purchases of shares of Common Stock under Section 423 Offerings and any remaining portion of such
maximum number of shares of Common Stock may be used to satisfy purchases of shares of Common Stock under Non-423 Offerings. If
the total number of shares of Common Stock to be issued on any Purchase Date exceeds the maximum number of shares of Common Stock
available for issuance under the Plan, the Company shall (i) make a pro-rata allocation of the shares of Common Stock available
for delivery and distribution in as nearly a uniform manner as shall be practicable and the Committee determines to be equitable,
(ii) return the balance of payroll deductions credited to the account of each Participant under the Plan as promptly as practicable,
and (iii) have the discretion to terminate any or all Offering Periods then in effect pursuant to Section 5(a) hereof. If any rights
granted under the Plan terminate for any reason without having been exercised, the shares of Common Stock not purchased under such
rights shall again become available for issuance under the Plan.

 

(b)              
Participant’s Interest in Rights to Purchase Common Stock.

 

(i)              
Until the applicable shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company),
a Participant shall only have the rights of an unsecured creditor with respect to such shares of Common Stock, and no right to
vote or receive dividends or any other rights as a stockholder shall exist with respect to such shares of Common Stock.

 

(ii)             
The Participant shall have no interest in the shares of Common Stock covered by a right to purchase such shares of Common
Stock under the Plan until such right has been exercised.

 

4.                 
Eligibility and Participation.

 

(a)              
Enrollment and Participation.

 

(i)              
Any individual who, on the day preceding an Offering Commencement Date, qualifies as an Eligible Employee, may elect to
become a Participant in the Plan for such Offering Period by completing a Subscription through the online enrollment process through
the Company’s designated Plan broker or, if permitted by the Company, submitting a Subscription, in the form prescribed for
this purpose by the Company. The Subscription shall be filed with the Company in accordance with the procedures as established
by the Company. Eligible Employees may not have more than one (1) Subscription in effect with respect to any Offering Period.

 

(ii)             
 Once enrolled in the Plan, a Participant shall continue to participate in the Plan until such Participant ceases to be
an Eligible Employee or withdraws from the Plan in accordance with Section 6(c) hereof. Under the foregoing automatic enrollment
provisions, payroll deductions will continue at the level in effect immediately prior to any new Offering Commencement Date, unless
changed in advance by the Participant in accordance with Section 6(c) hereof. A Participant who withdraws from the Plan in accordance
with Section 6(c) hereof may again become a Participant if such person is then an Eligible Employee, by following the procedure
described in Section 4(a)(i) hereof.

 

     

    7

    

 

(b)              
Limitations on Participation.

 

(i)              
Notwithstanding any provisions of the Plan to the contrary, no Eligible Employee shall be granted a right to purchase shares
of Common Stock pursuant to the Plan:

 

(A)            
if, immediately after the option is granted, such Eligible Employee owns shares of Common Stock possessing five percent
(5%) or more of the total combined voting power or value of all classes of Common Stock (for purposes of this Section 4(b)(i)(A),
the rules of Section 424 of the Code shall apply in determining stock ownership of any Eligible Employee), pursuant to the requirements
of Section 423(b)(3) of the Code; or

 

(B)            
which right permits such Eligible Employee to purchase shares of Common Stock under all employee stock purchase plans of
the Company and its Affiliates that shall accrue at a rate which exceeds $25,000 in Fair Market Value of the Common Stock (determined
at the time such right to purchase Common Stock is granted) for each calendar year in which such right is outstanding, pursuant
to the requirements of Section 423(b)(8) of the Code. When applying the limitations of this Section 4.02(a)(ii), the right to purchase
Common Stock under an option accrues when the option (or any portion thereof) first becomes exercisable during the calendar year,
the right to purchase Common Stock under an option accrues at the rate provided in the option, but in no case may such rate exceed
$25,000 of Fair Market Value of such Common Stock (determined at the time such option is granted) for any one (1) calendar year,
and a right to purchase Common Stock which has accrued under one option granted pursuant to the Plan may not be carried over to
any other option to purchase Common Stock.

 

(C)            
Prior to any Offering Commencement Date, the Company shall specify, with respect to the Purchase Date for the relevant Offering
Period, a maximum number of shares of Common Stock that may be purchased by any Participant.

 

(D)             Prior
to any Offering Commencement Date, the Committee may specify, with respect to the Purchase Date for the relevant Offering
Period, a maximum aggregate number of shares of Common Stock that may be purchased by all Participants. If the aggregate
purchase of shares of Common Stock issuable on such Purchase Date would exceed any such maximum aggregate number, then, in
the absence of any Committee action otherwise, a pro-rata (based on each Participant’s accumulated payroll deductions)
allocation of the shares of Common Stock available will be made in as nearly a uniform manner as will be practicable and
equitable.

 

     

    8

    

 

5.                 
Offering Periods.

 

(a)              
Offering Periods.

 

(i)              
The Plan shall be implemented by consecutive Offering Periods with new Offering Commencement Dates commencing on the first
Trading Day on or after January 1 and July 1 of each year (or at such other times as may be determined by the Committee). Each
Offering Period shall comply with the requirements of Section 423(b)(5) of the Code. The Committee shall have the power to terminate
or change the duration and/or frequency of the Offering Periods (including the Offering Commencement Date) with respect to future
Offering Periods without shareholder approval. Any such changes shall be announced prior to the scheduled beginning of the affected
Offering Period.

 

(ii)             
A Subscription that is in effect on an Offering End Date will automatically be deemed to be a Subscription for the Offering
Period that commences immediately following such Offering End Date, provided that the Participant is still an Eligible Employee
and has not withdrawn such Participant’s Subscription in accordance with Section 6(c) hereof. Payroll deductions will continue
at the level in effect immediately prior to the new Offering Commencement Date, unless changed in advance by the Participant in
accordance with Section 6(c) hereof.

 

(b)              
Grant of Option. On each Offering Commencement Date, each Participant shall be automatically granted an option to
purchase as many shares of Common Stock (rounded down to the nearest whole share of Common Stock) as may be purchased with such
Participant’s payroll deductions during the related Offering Period at the Purchase Price, subject to the limitations set
forth in Sections 3(a) and 4(b) hereof.

 

6.                 
Payroll Deductions.

 

(a)              
Amount of Payroll Deductions. An Eligible Employee’s Subscription shall authorize payroll deductions at a rate,
in whole percentages, of no less than one percent (1%) and no more than fifteen percent (15%) of such Participant’s Base
Compensation on each payroll date that the Subscription is in effect. Payroll deductions shall commence on the first payroll date
following the Offering Commencement Date and shall continue until the Participant changes the rate of such Participant’s
payroll deductions or terminates such Participant’s participation in the Plan, in each case, as provided in Section 6(c)
hereof.

 

     

    9

    

 

(b)               Participant’s
Account. All payroll deductions made with respect to a Participant shall be credited to such Participant’s
recordkeeping account under the Plan. A Participant may not make any separate cash payment into such account; provided, however,
the Committee may, in its sole discretion, allow Eligible Employees to participate in the Plan via cash contributions instead
of payroll deductions if (i) payroll deductions are not permitted under applicable local law or (ii) the Committee
determines, in its sole discretion, that cash contributions are permissible under Section 423 of the Code. No interest shall
accrue or be paid on any amount withheld from a Participant’s pay under the Plan or credited to the Participant’s
account, unless required by law. Except as provided in this Section 6(b) hereof all amounts in a Participant’s account
shall be used to purchase whole shares of Common Stock and no cash refunds shall be made from such account. Any amounts that
are insufficient to purchase whole shares shall be credited to the Participant’s account, and added to any fractional
amounts resulting on subsequent Purchase Dates. Upon liquidation or other closing of a Participant’s account, any
fractional amounts shall be paid in cash to the Participant based on the then-current Fair Market Value of the Common Stock.
In addition, any amounts that are withheld but unable to be applied to the purchase of Common Stock because of the
limitations of Section 4(b) hereof shall be returned to the Participant without interest and shall not be used to purchase
shares of Common Stock with respect to any other Offering Period under the Plan.

 

(c)              
No Changes in Payroll Deductions; Termination of Subscription.

 

(i)              
Subject to such restrictions, prohibitions and procedures established by the Committee, in its sole discretion, following
the Offering Commencement Date associated with an Offering Period, a Participant may terminate such Participant’s Subscription
for the Offering Period (but may not otherwise increase or decrease such Participant’s level of elected payroll deductions
under the Subscription with respect to such Offering Period) at any time prior to the Purchase Date.

 

(ii)             
Any termination of a Subscription shall only be deemed effective if such termination is executed pursuant to procedures
established by the Company. If a Participant terminates such Participant’s Subscription with respect to an Offering Period,
the accumulated payroll deductions in such Participant’s account at the time the Subscription is withdrawn shall be paid
without interest to such Participant as soon as practicable after receipt of such Participant’s notice of withdrawal and
such Participant’s Subscription for the current Offering Period will be automatically terminated, and no further contributions
for the purchase of shares of Common Stock will be made during the Offering Period or subsequent Offering Periods until such Participant
re-enrolls in the Plan pursuant to Section 4(a)(i) hereof. Any re-enrollment in the Plan shall be effective only at the commencement
of a subsequent Offering Period.

 

7.                 
Termination of Employment.

 

(a)               General.
Termination of a Participant’s employment for any reason, including retirement, death or the failure of such
Participant to remain an Eligible Employee of the Company or an Affiliate, shall immediately terminate such
Participant’s participation in the Plan. In such event, the accumulated payroll deductions in such Participant’s
account at the termination of such Participant’s employment shall be paid without interest to such Participant (or in
the case of his or her death, to the persons entitled thereto under Section 11(e) hereof) as soon as practicable after such
termination of such Participant’s employment and such Participant’s Subscription for the current Offering Period
will be automatically terminated, and no further contributions for the purchase of shares of Common Stock will be made during
the Offering Period or subsequent Offering Periods. For purposes of this Section 7, an Eligible Employee shall not be deemed
to have terminated employment or failed to remain in the continuous employ of the Company or an Affiliate in the case of sick
leave, military leave, or any other leave of absence approved by the Company; provided, however, that such
leave of absence is for a period of not more than ninety (90) days or re-employment upon the expiration of such leave is
guaranteed by contract or statute.

 

     

    10

    

 

(b)              
Transfer of Employment. Unless otherwise determined by the Committee, a Participant whose employment transfers or
whose employment terminates with an immediate rehire (with no break in service) by or between the Company or a Designated Company
will not be treated as having terminated employment for purposes of participating in the Plan or an Offering; however, if a Participant
transfers from a Section 423 Offering to a Non-423 Offering, the exercise of the Participant’s option will be qualified under
the Section 423 Offering only to the extent that such exercise complies with Section 423 of the Code. If a Participant transfers
from a Non-423 Offering to a Section 423 Offering, the exercise of the Participant’s option will remain non-qualified under
the Non-423 Offering.

 

 

8.                 
Exercise of Rights to Purchase Common Stock.

 

(a)              
Automatic Exercise.

 

(i)              
Unless a Participant terminates such Participant’s Subscription as provided in Section 6(c) hereof, a Participant’s
right to purchase shares of Common Stock will be automatically exercised on each Purchase Date for the applicable Offering Period.
The right to purchase shares of Common Stock will be exercised by using the accumulated payroll deductions in such Participant’s
account as of each such Purchase Date to purchase the maximum number of whole shares of Common Stock that may be purchased at the
Purchase Price (rounded down to the nearest whole share). The number of shares of Common Stock that will be purchased for each
Participant on the Purchase Date shall be determined by dividing (i) such Participant’s accumulated payroll deductions in
such Participant’s account as of the Purchase Date by (ii) the Purchase Price.

 

(ii)              At
the time an option granted under the Plan is exercised, in whole or in part, or at the time some or all of the shares of
Common Stock issued to a Participant under the Plan are disposed of, the Participant must make adequate provisions for any
applicable federal, state or any other tax liability payable to any authority including taxes imposed by jurisdictions
outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the
Purchase Date or the disposition of the shares of Common Stock. In their sole discretion, and except as otherwise determined
by the Committee, the Company or the Designated Company that employs the Participant may satisfy their withholding
obligations by (a) withholding from the Participant’s wages or other compensation, (b) withholding a sufficient whole
number of shares of Common Stock otherwise issuable following purchase having an aggregate fair market value sufficient to
pay the withholding obligations required to be withheld with respect to the shares of Common Stock, or (c) withholding from
proceeds from the sale of shares of Common Stock issued upon purchase, either through a voluntary sale or a mandatory sale
arranged by the Company.

 

     

    11

    

 

(b)              
Delivery of Common Stock.

 

(i)              
As promptly as practicable after each Purchase Date, the number of shares of Common Stock purchased by each Participant
pursuant to Section 8(a) hereof shall be deposited into an account established in the Participant’s name with the broker
designated by the Company for such purpose.

 

(ii)             
Shares of Common Stock that are purchased under the Plan will be held in an account in the Participant’s name in uncertificated
form. Furthermore, shares of Common Stock to be delivered to a Participant under the Plan will be registered in the “street
name” of such Participant.

 

9.                 
Changes in Capitalization; Adjustments Upon Dissolution, Liquidation or Change in Control.

 

(a)              
Changes in Capitalization. Subject to any required action by the stockholders of the Company, (i) the number of shares
of Common Stock covered by each option under the Plan that has not yet been exercised, (ii) the number of shares of Common Stock
that have been authorized for issuance under the Plan but have not yet been placed under option (collectively, the “Reserves”),
(iii) the number of shares of Common Stock set forth in Section 3(a), (iv) the Purchase Price per share and (v) the maximum number
of shares of Common Stock that may be purchased by any Participant on any Purchase Date during an Offering Period, shall, if applicable,
be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, subdivision, combination or reclassification of the Common Stock (including any such
change in the number of shares of Common Stock effected in connection with a change in domicile of the Company), or any other increase
or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company, or any increase or
decrease in the value of a share of Common Stock resulting from a spinoff or split-up; provided, however, that conversion
of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.”
Such adjustment shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive. Except
as expressly provided herein, 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 or price of
shares of Common Stock subject to an option.

 

(b)              
Adjustments Upon Dissolution, Liquidation or Change in Control.

 

(i)                
In the event of a dissolution or liquidation of the Company, any Offering Period then in progress will terminate immediately
prior to the consummation of such action, unless otherwise provided by the Committee.

 

     

    12

    

 

(ii)             
 Unless otherwise provided in the applicable agreement, the consummation of which will result in a Change in Control, in
the event of a Change in Control, the applicable Offering Period will be shortened by setting a New Purchase Date on which such
Offering Period shall end; provided, that such New Purchase Date may be no later than the date of the consummation of the
Company’s proposed Change in Control. Prior to the New Purchase Date, the Committee will notify each Participant, in writing
or electronically, that the applicable Purchase Date has been changed to the New Purchase Date and that the Participant’s
option will be exercised automatically on the New Purchase Date, unless such Participant has withdrawn from the Offering Period
prior to the New Purchase Date as provided in Section 6(c) hereof. Alternatively, the Committee and the successor corporation may
provide that each outstanding option under the Plan will be assumed or an equivalent option will be substituted by the successor
corporation or a parent or subsidiary of the successor corporation. For purposes of this Section 9(b)(ii) hereof, an option granted
under the Plan shall be deemed to be assumed, without limitation, if, at the time of issuance of the stock or other consideration
upon a Change in Control, each holder of an option under the Plan would be entitled to receive the same number and kind of shares
of stock or the same amount of property, cash or securities as such holder would have been entitled to receive upon the occurrence
of the transaction if the holder had been, immediately prior to the transaction, the holder of the number of shares of Common Stock
covered by the option at such time (after giving effect to any adjustments in the number of shares of Common Stock covered by the
option as provided for in Section 9(a) hereof; provided, however, that if the consideration received in the transaction
is not solely common stock of the successor corporation or its parent (as defined in Section 424(e) of the Code), the Committee
may, with the consent of the successor corporation, provide for the consideration to be received upon exercise of the option to
be solely common stock of the successor corporation or its parent equal in Fair Market Value to the per share consideration received
by holders of shares of Common Stock in the transaction.

 

10.             
Administration.

 

(a)              
Committee to Administer the Plan. The Committee shall be responsible for the administration of the Plan.

 

(b)               Authority
of Committee. The Committee (or its designee) shall have full and plenary authority, subject to the provisions of the
Plan, to (i) promulgate such rules and regulations as it deems necessary for the proper administration of the Plan, (ii)
interpret the provisions and supervise the administration of the Plan (including, without limitation, to adopt such
procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign
nationals or employed outside the U.S., the terms of which sub-plans may take precedence over other provisions of this Plan,
with the exception of Section 3 hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of this
Plan shall govern the operation of such sub-plan), (iii) determine eligibility and adjudicate all disputed claims filed under
the Plan, including whether Eligible Employees will participate in a Section 423 Offering or a Non-423 Offering and which
Subsidiaries and Affiliates of the Company will be Designated Companies participating in either a Section 423 Offering or a
Non-423 Offering, and (iv) take all action in connection therewith or in relation thereto as it deems advisable. All
determinations by the Committee under the Plan shall, to the full extent permitted by law, be final and binding on upon all
parties. The Company shall pay all expenses incurred in the administration of the Plan. No
member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with
respect to the Plan, and all members of the Committee shall be fully indemnified by the Company with respect to any such
action, determination or interpretation.

11.             
Miscellaneous.

 

(a)              
Amendment and Termination.

 

(i)                
The Board or the Committee may at any time and for any reason terminate the Plan. Except as provided in Section 9 hereof,
no such termination of the Plan may affect options previously granted, provided that the Plan or an Offering Period may be terminated
by the Committee on a Purchase Date or by the Board’s setting a new Purchase Date with respect to an Offering Period then
in progress if the Board determines that termination of the Plan and/or the Offering Period is in the best interests of the Company
and the stockholders or if continuation of the Plan and/or the Offering Period would cause the Company to incur adverse accounting
charges as a result of a change after the Effective Date of the Plan in the generally accepted accounting principles applicable
to the Plan. Either the Board or the Committee may amend the Plan. Except as provided in Section 9(a) and in this Section 11(a),
no amendment to the Plan shall make any change in any option previously granted that adversely affects the rights of any Participant.
In addition, to the extent necessary to comply with Rule 16b-3 or Section 423 of the Code (or any successor rule or provision or
any applicable law or regulation), the Company shall obtain stockholder approval in such a manner and to such a degree as so required.

 

(ii)             
Without stockholder consent and without regard to whether any Participant’s rights may be considered to have been
adversely affected, the Board or the Committee shall be entitled to change the Offering Period, limit the frequency and/or number
of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency
other than U.S. dollars, permit payroll tax withholding in excess of the amount designated by a Participant in order to adjust
for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting
and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common
Stock for each Participant properly correspond with amounts withheld from the Participant’s compensation, and establish such
other limitations or procedures as the Board or the Committee determines, in its sole discretion, are advisable and consistent
with the Plan.

 

(iii)           
In the event the Committee determines that the ongoing operation of the Plan may result in unfavorable financial accounting
consequences, the Committee may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan
to reduce or eliminate such accounting consequence including, but not limited to:

 

     

    14

    

 

(A)            
 amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting
Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;

 

(B)             
altering the Purchase Price for any Offering Period;

 

(C)             
shortening any Offering Period by setting a new Purchase Date, including an Offering Period underway at the time of the
Committee action; and

 

(D)            
reducing the maximum percentage of Base Compensation a Participant may elect to have deducted from payroll.

 

Such modifications or amendments
will not require stockholder approval or the consent of any Plan Participants.

 

(iv)            
Upon termination of the Plan, the date of termination shall be considered a Purchase Date, and any cash remaining in Participant
accounts will be applied to the purchase of Common Stock, unless determined otherwise by the Board. Upon termination of the Plan,
the Board shall have authority to establish administrative procedures regarding the exercise of outstanding rights to purchase
shares of Common Stock or to determine that such rights shall not be exercised.

 

(b)              
Use of Funds. All payroll deductions received or held by the Company or any Affiliate under this Plan may be used
by the Company or such Affiliate for any corporate purpose and neither the Company nor such Affiliate shall be obligated to segregate
such payroll deductions.

 

(c)              
Transferability; Restrictions on Disposition.

 

(i)                
Neither payroll deductions credited to a Participant’s account nor any rights with regard to the exercise of a right
to purchase Common Stock or to receive shares of Common Stock under the Plan may be assigned, transferred, pledged, or otherwise
disposed of in any way by the Participant other than by will or the laws of descent and distribution or as provided in Sections
7(a) or 11(e) hereof. Any such attempted assignment, transfer, pledge, or other disposition shall be void ab initio. During a Participant’s
lifetime, rights to purchase shares of Common Stock that are held by such Participant shall be exercisable only by such Participant.

 

(ii)              The
Committee may, in its sole discretion, place restrictions on the sale or transfer of shares of Common Stock purchased under
the Plan by notice to all Participants of the nature of such restrictions given in advance of the Offering Commencement Date
of such Offering Period. Any certificates issued for shares that are restricted pursuant to this Section 11(c)(ii) hereof,
shall, in the discretion of the Committee, contain a legend disclosing the nature and duration of the restriction (including
a description of the restricted period). Any such restrictions and exceptions determined by the Committee shall be applicable
equally to all shares of Common Stock purchased during the Offering Period for which the restrictions are first applicable.
In addition, any restrictions and exceptions applicable to the Common Stock shall remain applicable during subsequent
Offering Periods unless otherwise determined by the Committee. If the Committee should change or eliminate any restrictions
for a subsequent Offering Period, notice of such action shall be given to all Participants.

 

     

    15

    

 

(d)              
Term; Stockholder Approval of the Plan. The Plan shall be effective upon its approval by the Board and shall be approved
by the stockholders of the Company, in any manner permitted by applicable corporate law, within twelve (12) months before or after
the Plan is adopted by the Board. No purchase of shares of Common Stock pursuant to the Plan shall occur prior to such stockholder
approval. The Plan shall terminate on the earliest of (i) termination of the Plan by the Board or the Committee (which termination
may be effected by the Board or the Committee at any time), (ii) the tenth (10th) anniversary of the approval of the
Plan by the stockholders or (iii) issuance of all of the shares of Common Stock available for issuance under the Plan.

 

(e)              
Designation of a Beneficiary.

 

(i)              
If permitted by the Company, a Participant may file a designation of a beneficiary who is to receive any shares of Common
Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent
to a Purchase Date on which the option is exercised but prior to delivery to such Participant of such shares and cash. In addition,
if permitted by the Company, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s
account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married
and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

 

(ii)             
Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Company.
In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living
at the time of such Participant’s death, the Company will deliver such shares and/or cash to the executor or administrator
of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives
of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may
designate.

 

(iii)            
All beneficiary designations will be in such form and manner as the Company may designate from time to time. Notwithstanding
Sections 11(e)(i) and (ii) above, the Company and/or the Committee may decide not to permit such designations by Participants in
non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

 

     

    16

    

 

(f)               
No Employment Rights; Effect of the Plan.

 

(i)              
 The Plan does not, directly or indirectly, create in any employee or class of employees, any right with respect to continuation
of employment with the Company or any of its Affiliates, and it shall not be deemed to interfere in any way with the right of the
Company or any Affiliate employing such person to terminate, or otherwise modify, an employee’s employment at any time.

 

(ii)             
The provisions of the Plan shall, in accordance with its terms, be binding upon, and inure to the benefit of, all successors
of each Participant, including, without limitation, such Participant’s estate and the executors, administrators or trustees
thereof, heirs and legatees, and any receiver, trustee in bankruptcy or representative of creditors of such Participant.

 

(g)              
Governing Law; Jurisdiction; Waiver of Jury Trial.

 

(i)               
The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to
contracts made and performed wholly within the State of Delaware, without giving effect to the conflict of laws provisions thereof.

 

(ii)             
Any suit, action or proceeding with respect to the Plan, or any judgment entered by any court of competent jurisdiction
in respect of any thereof, shall be resolved only in the courts of the State of Delaware and the appellate courts having jurisdiction
of appeals in such courts. In that context, and without limiting the generality of the foregoing, the Company and each Participant
shall irrevocably and unconditionally (A) submit in any proceeding relating to the Plan or any option, or for the recognition and
enforcement of any judgment in respect thereof (a “Proceeding”), to the exclusive jurisdiction of the courts
of the State of Delaware, the court of the United States of America for the District of Delaware, and appellate courts having jurisdiction
of appeals from any of the foregoing, and agree that all claims in respect of any such Proceeding shall be heard and determined
in such Delaware State court or, to the extent permitted by law, in such federal court, (B) consent that any such Proceeding may
and shall be brought in such courts and waives any objection that the Company and each Participant may now or thereafter have to
the venue or jurisdiction of any such Proceeding in any such court or that such Proceeding was brought in an inconvenient court
and agree not to plead or claim the same, (C) waive all right to trial by jury in any Proceeding (whether based on contract, tort
or otherwise) arising out of or relating to the Plan or any option, (D) agree that service of process in any such Proceeding may
be effected by mailing a copy of such process by registered or certified mail (or any substantially similar form of mail), postage
prepaid, to such party, in the case of a Participant, at the Participant’s address shown in the books and records of the
Company or, in the case of the Company, at the Company’s principal offices, attention General Counsel, and (E) agree that
nothing in the Plan shall affect the right to effect service of process in any other manner permitted by the laws of the State
of Delaware.

 

     

    17

    

 

(h)               Code
Section 409A. Options granted under a Section 423 Offering are exempt from the application of Section 409A of the Code
and any ambiguities herein will be interpreted to so be exempt from Section 409A of the Code. Options granted under a Non-423
Offering are intended to be exempt from Section 409A of the Code pursuant to Treasury Regulation §409A-1(b)(5)(i)(A). In
furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Committee determines that
an option granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an
option under the Plan to be subject to Section 409A of the Code, the Committee may amend the terms of the Plan and/or of an
outstanding option granted under the Plan, or take such other action the Committee determines is necessary or appropriate, in
each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted
under the Plan from or to allow any such options to comply with Section 409A of the Code, but only to the extent any such
amendments or action by the Committee would not violate Section 409A of the Code. Notwithstanding the foregoing, the Company
shall have no liability to a Participant or any other party if the option to purchase Common Stock under the Plan that is
intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken
by the Committee with respect thereto. The Company makes no representation that the option to purchase Common Stock under the
Plan is compliant with Section 409A of the Code.

 

(i)                
Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan
shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated
by the Company for the receipt thereof.

 

(j)                
Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for
any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability shall not affect the remaining
parts of the Plan, and the Plan shall be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal
or unenforceable provision had not been included.

 

     

    18

    

 

12.             
 Conditions Upon Issuance of Shares of Stock. Shares of Common Stock shall not be issued with respect to an option
unless the exercise of such option and the issuance and delivery of such shares of Common Stock pursuant thereto shall comply with
all applicable provisions of law, including, without limitation, the Securities Act, the Exchange Act, applicable state securities
laws and the requirements of any stock exchange upon which the shares of Common Stock may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to such compliance. Further, all shares of Common Stock acquired
pursuant to the Plan shall be subject to the Company’s policies concerning compliance with securities or exchange control
laws and regulations, as such policies may be amended from time to time. The issuance of shares of Common Stock under the Plan
shall be subject to compliance with all applicable requirements of federal, state or non-U.S. law with respect to such securities.
The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s
legal counsel to be necessary to the lawful issuance and sale of any shares of Common Stock under the Plan shall relieve the Company
of any liability in respect of the failure to issue or sell such shares of Common Stock as to which such requisite authority shall
not have been obtained. As a condition to the exercise of an option, the Company may require the person exercising such option
to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation
and to represent and warrant at the time of any such exercise that the shares of Common Stock are being purchased only for investment
and without any present intention to sell or distribute such Common Stock if, in the opinion of counsel for the Company, such a
representation is required by any of the aforementioned applicable provisions of law.
