MEDICINE LLC (“D3 Medicine”), has entered into the Membership Interest Purchase Agreement, dated as of September 2,
2016 (the “Purchase Agreement”) among Certara USA, Inc. and the Sellers listed on Exhibit A to the
Purchase Agreement; and


 


WHEREAS, contingent on the Closing (as defined
in the Purchase Agreement), the Company has offered the Executive employment on the terms of this Agreement:


 


1.            Employment
Duties and Acceptance.


 


1.1            Employment
by the Company. Subject to Closing and effective as of September 2, 2016 (“Start Date”), the Company
shall employ the Executive to render exclusive and full-time services in the capacity of President of the Company, or such other
role or capacity as the Company may reasonable consider appropriate on the terms and conditions of this Agreement.


 


1.2            Duties
and Responsibilities. The Executive shall have duties and responsibilities consistent with his position, subject to the oversight
and direction by the Chief Executive Officer and the board of directors of the Company or its direct or indirect parent entity,
or their respective designee (each, the “Board”). The Executive shall devote all of the Executive’s working
time and efforts to the business and affairs of the Company. Executive shall not, without the prior approval of the Board, whether
for compensation or otherwise, directly or indirectly, alone or as a member or an employee of any partnership or other organization,
be actively engaged in or concerned with, any other business duties or personal pursuits which interfere with the performance of
the Executive’s responsibilities under this Agreement. The terms set out in this Agreement will continue to govern the Executive’s
employment with the Company despite any changes from time to time to the Executive’s position, duties and responsibilities,
Salary, working hours or place of employment unless otherwise agreed in writing.


 


1.3            Acceptance
of Employment by the Executive. The Executive accepts such employment and shall render the services described above. Subject
to appointment by the Board as such, the Executive may also serve as an officer of any other entity controlled by, or under common
control with, the Company, and as a director of the Company and of any other entity controlled by or under common control with
the Company, in each case without any compensation therefor other than that specified in this Agreement. Upon request, or upon
termination of employment with Company hereunder for any reason, the Executive shall, upon request, resign as a director or officer
of the Company and of any other entity controlled by, or under common control with, the Company.




    	 	 	 



     


    

 


1.4            Place
of Employment. The Executive’s principal place of employment shall be Melbourne, Australia (the “Employment
Location”). The Executive will undertake travel both within and outside Australia as may be necessary for the proper
performance of the Executive’s duties. The Executive will not be entitled to additional compensation for such travel, but
travel expenses for approved travel will be paid for by the Company in accordance with the Company’s policy.


 


2.            Term
of Employment. The stated term of employment under this Agreement (the “Term”) shall commence
on the Start Date and shall continue until Executive ceases to be employed by the Company for any reason.


 


3.            Compensation.


 


3.1            Salary.
As compensation for all services to be rendered pursuant to this Agreement, the Company shall pay the Executive during the Term
initially a total compensation package of US $250,000.00 per annum, payable not less frequently than monthly, less such taxes and
deductions as shall be required to be withheld by applicable laws and regulations (the “Salary”). The Executive’s
Salary is comprised of base salary and superannuation contributions in accordance with Section 3.2. The Executive’s
Salary is inclusive of all entitlements the Executive may have under an award, industrial instrument or at law. As this Agreement
undertakes to provide the Executive with a guarantee of the Executive’s Salary over the period of the Executive’s employment,
and the Executive’s guaranteed Salary exceeds the high income threshold under applicable laws, no industrial award (including
any modern award) will apply to the Executive during the Executive’s employment with the Company. The Board may, in its sole
discretion, determine to provide additional benefits or incentives to the Executive from time to time. Executive’s Salary
shall be reviewed once per year. A review does not necessarily mean an increase in Salary. Whether or not the Executive’s
Salary is increased after any such review is in the sole discretion of the Company. Any Salary increase is neither indicative or
determinative of the Executive’s right to a Salary increase in any subsequent year.


 


3.2            Superannuation
Contributions. As part of the Salary referred to in Section 3.1, the Company will contribute the minimum amount required
to avoid any charge under applicable superannuation laws, to a complying superannuation fund nominated by the Executive in writing.
If the Executive does not nominate such a fund, the Company will make contributions into the Employer’s default complying
superannuation fund.


 


3.3            Incentive
Bonus. In addition to his Salary, Executive shall be eligible to be considered for an annual discretionary incentive bonus
in an amount up to 30% of Executive’s year to date base salary for the relevant year (the “Incentive Bonus”).
Executive shall maintain the same eligibility to receive an Incentive Bonus, for a period of two (2) years after Closing,
as the Executive did prior to Closing. In addition, following such two (2) year period, the Company will evaluate adjusting
the Incentive Bonus but shall not materially reduce the bonus opportunity for the Executive. The applicable criteria for receiving
an Incentive Bonus payment shall be established by the Board and communicated to Executive annually at its sole discretion. Any
earned Incentive Bonus will be paid at such time that bonuses are generally paid and as determined by the Board. Any Incentive
Bonus payment will be inclusive of superannuation contributions required to be paid with respect to that Incentive Bonus for the
Company to avoid a charge under applicable superannuation laws. Subject to the Executive’s rights to maintain eligibility
to an Incentive Bonus as set out above, the Company may amend, replace or terminate this discretionary incentive bonus plan at
any time in its sole discretion. Without prejudice to such sole discretion of the Company and to the specific rules of such
discretionary incentive bonus plan as may from time to time be operated by the Company, the following general principles shall
apply to the payment of any Incentive Bonus by the Company to the Executive:


 


(a)            the
level of Incentive Bonus paid (if any) by the Company to the Executive in any given year shall be neither indicative nor determinative
of the Executive’s right to a bonus, or the level of any bonus payable, in any subsequent year;


 






    	 	 	 



     


    

 


(b)            no
payment or part payment of any Incentive Bonus, whether calculated on a pro rata basis or on any other basis, shall be paid to
the Executive if, as at the relevant payment date, the Executive has ceased to be an employee of the Company or is serving notice
of termination of employment regardless of the reasons for such termination and the Executive will not be entitled to receive any
compensation in lieu thereof; and


 


(c)            Incentive
Bonuses shall not form part of the Executive’s normal compensation package and, therefore, will not be taken into account
with respect to calculating any payment in lieu of notice, termination payment, or redundancy or severance pay, if any. Incentive
Bonuses shall also not form part of the Executive’s compensation for the purposes of any Company or Group benefit plan.


 


3.4            Expenses.
Subject to policies applicable to executives of the Company generally, as may from time to time be established by the Board, the
Company shall pay or reimburse the Executive for reasonable travel, entertainment and other business expenses actually incurred
or paid by the Executive during the Term in the performance of the Executive’s services under this Agreement, and which expenses
are consistent with the Company’s policies in effect from time to time with respect to such travel, entertainment and other
business expenses, upon presentation of expense statements or vouchers or such other supporting information as the Company may
require.


 


3.5            Annual
Leave. The Executive shall be entitled to paid annual leave in accordance with Company policy as in place from time to time
and applicable laws. Executive understands that it is the Company’s intention to provide an unlimited annual leave policy,
provided, however, the Company reserves the right to modify its annual leave policy at any time in its discretion. On taking annual
leave, you will be deemed to take your accrued statutory entitlement to annual leave prior to any discretionary annual leave entitlement
under the Company’s leave policy. On cessation of employment, you will be paid out any accrued but untaken annual leave in
accordance with your entitlements under the the Fair Work Act 2009 (Cth) (“FW Act”). Only statutory minimum
leave entitlements will accrue and accumulate under the FW Act, any discretionary leave entitlement provided under the Company’s
policy will be forfeited if not used by the employee at the end of the calendar year.


 






    	 	- 3 -	 



     


    

 


3.6            Personal/Carer’s
Leave. The Executive shall be entitled to accrue 10 days’ personal/carer’s leave per year of service in accordance
with applicable laws. The Executive will, where practicable, ensure that the Executive notifies the Company of any proposed absence
due to personal illness or injury or carer’s responsibilities and the expected date of the Executive’s return to work.
The Company requires the Executive to produce a medical certificate for any sick leave in excess of one day and a statutory declaration
for any carer’s leave taken. Personal/carer’s leave (including sick leave) will accrue from year to year in accordance
with applicable laws but will not be paid out on cessation of the Executive’s employment.


 


3.7            Other
leave entitlements. The Executive is entitled to other forms of leave including long service leave, compassionate leave, community
service leave and parental leave in accordance with applicable law.


 


4.            Suspension
and Termination.


 


4.1            Suspension.
The Company has the right to suspend the Executive from duties, with pay, where the Company considers it necessary to adequately
investigate allegations of misconduct or impropriety against or involving the Executive.


 


4.2            Termination
with Notice. The Executive’s employment may be terminated by either party by giving six month’s written notice
to the other party, or in the case of the Company, the Company may elect at its sole discretion to pay the Executive a payment
in lieu of all or part of the notice period. For the avoidance of doubt, the payment in lieu of notice will be calculated on the
Executive’s Salary only.


 


4.3            Termination
upon Death. If the Executive dies while employed by the Company, this Agreement shall automatically terminate and the Executive
or the Executive’s estate shall be entitled only to receive the Accrued Obligations payable through the date of such death.


 


4.4            Termination
upon Permanent Illness or Injury. If the Executive becomes ill (whether physically or mentally) or injured while employed by
the Company (whether totally or partially) so that the Executive is unable substantially to perform the inherent requirements of
the Executive’s role hereunder with or without reasonable accommodation as determined, in good faith, by the Board following
consultation with medical advisors selected by the Board for (a) a period of more than three consecutive months, or (b) for
shorter periods aggregating three months during any 12 month period (in each of clauses (a) and (b), such time periods shall
exclude any period that the Executive is on paid personal/carer’s leave), the Company may, except as prohibited by law, by
written notice to the Executive, terminate the Executive’s employment with immediate effect. In the event of termination
of the Executive’s employment by the Company pursuant to this Section 4.4, the Executive shall be entitled only to receive
the Accrued Obligations payable through the date of termination.


 






    	 	- 4 -	 



     


    

 


4.5            Termination
without Notice. Notwithstanding any of the other provisions of this Agreement, the Company may at any time terminate the Executive’s
employment without notice and without any obligation to make a payment in lieu of notice if the Executive commits any misconduct
that would justify summary dismissal including, but not limited to, any of the following:


 


(a)            the
Executive commits any act of dishonesty, fraud or falsification of documentation;




 


(b)            the
Executive commits a serious or persistent breach of any of the provisions of this Agreement;

opinion of the Company, is likely to bring the Executive or the Company or any Company Group into serious disrepute;


 


(i)             the
Executive commits any act of bankruptcy or compounds with creditors; or


 


(j)             the
Executive is precluded by the Corporations Act from taking part in the management of a corporation, or is disqualified from holding
office as a director of any company by virtue of any legislation.

Agreement:


 


“Accrued Obligations” means
as of the date of Executive’s termination, (a) Executive’s earned but unpaid Salary, if any, through such date,

hereof may be waived, only by a written instrument signed by the parties making specific reference to this Agreement, or, in the
case of a waiver, by the party waiving compliance. No delay on the part of any party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof, nor shall any waiver on the part of any party of any right, power or privilege hereunder,

the exercise of any other right, power or privilege hereunder.

assignee or transferee assumes by operation of law or in a writing duly executed by the assignee or transferee all of the liabilities,
obligations and duties of the Company, as contained in this Agreement, either contractually or as a matter of law, as if no such
