Re:      Separation
Agreement


 


Dear Jill,


 


This letter sets forth the substance of the separation
agreement (the “Agreement”) which ISPECIMEN INC. (the “Company”)
is offering to you to aid in your employment transition.


 


Separation.
Your last day of work with the Company and your employment termination date will be October 24, 2022 (the “Separation
Date”).


 


The Company shall take steps to report your removal
as an officer and manager of the Company, or any related business entity, including removing references to you as an officer or manager
of the Company, on all applicable Company filings and registries.


 


You shall remain a non-executive director of the
Company for so long as you remain elected to the Board. As a non-executive director of the Company, you shall be eligible for director
compensation, in accordance with the Company’s by-laws and its Non-Employee Director Compensation Policy in effect as of October 1,
2022 (as may be amended), in a form and amount that is no less than the director compensation afforded to other non-executive directors
of the Company, and treating you as an Eligible Director with an initial Election Date of October 25, 2022 (with capitalized terms
defined in the aforementioned policy), subject further to the express understanding and agreement that you are not and will not be eligible
for the Initial Option Grant set forth in said policy.


 


1.            Accrued
Salary. On the Separation Date, the Company will pay you all accrued salary earned through the
Separation Date, subject to standard payroll deductions and withholdings. You will receive these payments regardless of whether or not
you sign this Agreement. You acknowledge that the Company has adopted an unlimited paid time off policy, and that, as of your Separation
Date, you have no accrued paid time off that requires reimbursement.


 


2.            Severance
Benefits. You are eligible for severance pursuant to Section 5(C) of your Employment
Agreement. If you execute, do not revoke, and return this Agreement within the timeframe specified herein (but no earlier than the Separation
Date) and comply fully with your obligations under this Agreement and Section 5(C) of the Employment Agreement, the Company
will provide you with the following severance benefits, in full satisfaction of the obligations under the Employment Agreement:


 


(a)            Severance.
Pursuant to Section 5(C)(i) of the Employment Agreement, the Company will pay you, as severance, the equivalent of twelve
(12) months of your base salary in effect as of the Separation Date (which equals a gross total of $325,000)
(the “Severance”). The Severance Payment shall be paid in equal instalments commencing on the Company’s first regular
payroll date after the Effective Date of this Agreement, as defined below, and ending on the twelve (12) month anniversary of the Effective
Date (“The Severance Pay Period”).

(b)            COBRA
Premiums. As an additional severance benefit, pursuant to Section 5(C)(iii) of the
Employment Agreement, if you are eligible for and timely elect to continue your health and dental insurance coverage under the Consolidated
Omnibus Budget Reconciliation Act of 1985 (“COBRA”), the Company will pay, as and when due to the insurance carrier or COBRA
administrator (as applicable), the full COBRA health and dental insurance premiums for you and your eligible dependents, if any, until
the expiration of your eligibility for the continuation coverage under COBRA. In the event you become covered under another employer’s
group health plan or otherwise cease to be eligible for COBRA coverage, you must immediately notify the Company, and the Company’s
obligation to pay COBRA premiums shall cease.


 


(c)            Partial
Acceleration. In accordance with Section 2.2 of the Restricted Stock Unit Agreement between
you and the Company dated June 21, 2021 (the “Restricted Stock Agreement”), the Company will accelerate vesting of the
shares subject to your equity awards, as detailed in Section 5 below.


 


(d)            Equity
Reporting. The Company acknowledges that, in an SEC Form S-8 form filing, the Company under-reported
the number of Company securities registered to you. The Company shall correct such reporting through the filing of an amended SEC Form S-8
on or before December 31, 2022.


 


3.            Benefit
Plans.


 


If you are currently participating in the Company’s
group health insurance plans, your participation as an employee will end on your Separation Date. Thereafter, to the extent provided by
the federal COBRA law or, if applicable, state insurance laws, and by the Company’s current group health and dental insurance policies,
you will be eligible to continue your group health and dental insurance benefits at your own expense, with the potential for certain payments
to be made by the Company as described in Section 2(b) above. Later, you may be able to convert to an individual policy through
the provider of the Company’s health insurance, if you wish.


 


Your participation in Employer-Sponsored Group
Life Insurance and Short and Long Term Disability Insurance will cease as of your last day of employment; however, you may elect to convert
your insurance by contacting The Standard within 31 days of your last day worked.


 


Deductions for the 401(k) Plan will end with
your last regular paycheck. You will receive information by mail concerning 401(k) plan rollover procedures should you be a participant
in this program.

You have the right to continue your current Health
Care Spending Account if you are participating in this program. Enclosed is the information concerning how to continue this benefit. Dependent
Care Spending Accounts cannot be continued. Your last full Spending Account payroll deductions will be processed in the last pay period
in October. Unless you elect to continue your Health Care Spending Account, you will only be eligible to claim expenses that you incurred
prior to the Separation Date.


 


You may be eligible for unemployment insurance benefits after
the Separation Date. Your state or commonwealth’s department of unemployment assistance, not the Company, will determine your eligibility
for such benefits. Please refer to Exhibit A for more information.


 


4.            Equity.


 


(a)            You
were awarded 52,084 restricted stock units (the “RSUs”) pursuant to the Company’s 2021 Amended and Restated Equity
Incentive Plan (the “Plan”) and the RSU Agreement. As of the Separation Date, 20,834 shares of the Company’s
common stock (“Common Stock”) have been delivered to you upon the settlement of your vested RSUs. Consistent with Section 2.2
of the RSU Agreement, and contingent upon your execution of this Agreement, the Company’s Board of Directors will modify and accelerate
your vesting schedule such that a certain portion of you unvested RSUs that would have vested after your Separation Date, had you remained
employed by the Company, shall be considered vested as of your Separation Date (the “Accelerated RSUs”). As a result of such
acceleration, 13,021 shares of Common Stock will be delivered to you upon the settlement of the Accelerated RSUs. You acknowledge
that this Section 5(a) of the Agreement fully satisfies the Company’s obligations set forth in Section 2.2 of the
Restricted Unit Agreement. With respect to the exercise of your vested RUSs, you shall have the option to either: (a) make a cash
payment to the Company for the aggregate exercise price; or (b) instruct the Company to withhold a number of RSUs then exercisable
with an aggregate fair market value as of the exercise date equal to the aggregate exercise price (a/k/a cashless exercise).


 


(b)            You
were awarded 13,021 performance share units (the “PSUs”) pursuant to the Plan and Performance Share Unit Agreement
between you and the Company dated June 21, 2021 (the “PSU” Agreement. As of the Separation Date, you are vested with
respect to 0 PSUs. Consistent with Section 5 of the PSU Agreement, your unvested PSUs are forfeit, and, as of your Separation
Date the Company has no further obligations to you under the PSU Agreement.


 


(c)            Other
Compensation or Benefits. You acknowledge that, except as expressly provided in this Agreement,
you will not receive any additional compensation, severance or benefits after the Separation Date.


 


5.            Expense
Reimbursements. You agree that, within ten (10) days of the Separation Date, you will submit
your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any,
for which you seek reimbursement. The Company will reimburse you for reasonable business expenses pursuant to its regular business practice.

6.            Return
of Company Property. Except with respect to such Company Property (as defined below) that you
possess that you reasonably need to fulfill your role as a director of the Company, including but not limited to any Company-issued laptop
computers currently within your possession, within three (3) days following the Separation Date, you agree to either: (1) return
to the Company all Company documents (and all copies thereof) and other Company property that you have had in your possession at any time,
including, but not limited to, Company files, notes, drawings, records, business plans and forecasts, financial information, specifications,
computer-recorded information, tangible property (including, but not limited to, computers), credit cards, entry cards, identification
badges and keys; and, any materials of any kind that contain or embody any proprietary or confidential information of the Company (and
all reproductions thereof) (“Company Property”); or (2) destroy any such Company Property in your possession and certify
the destruction of the same to the Company’s Board in writing. In connection with your obligations under this Section 6, on
your Separation Date, you shall deliver your Company-issued laptop computer to the Company’s Chief Information Officer for inspection
and data cataloguing. No data shall be “scrubbed” from such lap-top computer, however. After that process is completed, such
lap-top computer shall be promptly returned to you. Receipt of the severance benefits described in Section 2 of this Agreement is
expressly conditioned upon return of all Company Property except as otherwise noted in this Section 6.


 


7.      Confidential
Information and Post-Termination Obligations. Both during and after your employment you acknowledge
your continuing obligations, to the extent applicable, under your Noncompetition, Nonsolicitation, Nondisclosure and Inventions Agreement
(the “NNNIA”) a copy of which is attached hereto as Exhibit B. As you know, the Company will enforce its contract
rights. Please familiarize yourself with the enclosed agreement which you signed. Confidential information that is also a “trade
secret,” as defined by law, may be disclosed (A) if it is made (i) in confidence to a federal, state, or local government
official, either directly or indirectly, or to an attorney and (ii) solely for the purpose of reporting or investigating a suspected
violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made
under seal. In addition, in the event that you file a lawsuit for retaliation by the Company for reporting a suspected violation of law,
you may disclose the trade secret to your attorney and use the trade secret information in the court proceeding, if you: (A) file
any document containing the trade secret under seal; and (B) do not disclose the trade secret, except pursuant to court order.


 


8.            Non-Disparagement.
Both you and the Company agree not to disparage the other party, and the other party’s officers, directors, employees, shareholders
and agents, in any manner likely to be harmful to them or their business, business reputation or personal reputation; provided that both
you and the Company will respond accurately and fully to any question, inquiry or request for information when required by legal process.
The Company’s obligations under this Section are limited to Company representatives with knowledge of this provision, including,
but not limited to, the President and other “C-Suite” executives of the Company and all members of the Company’s Board
of Directors. Notwithstanding the foregoing, nothing in this Agreement shall (i) limit your right to voluntarily communicate with
the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Securities and
Exchange Commission, other federal government agency or similar state or local agency or to discuss the terms and conditions of your employment
with others to the extent expressly permitted by Section 7 of the National Labor Relations Act; or (ii) prevent either you or
the Company from responding truthfully to requests for information by any government agency.

11.      Notwithstanding
the foregoing, other than events expressly contemplated by this Agreement you do not waive or release rights or Claims that may arise
from events that occur after the date this waiver is executed or your right to enforce this Agreement and you are not releasing any right
of indemnification you may have for any liabilities arising from your actions within the course and scope of your employment with the
Company or within the course and scope of your role as an officer of the Company. Also excluded from this Agreement are any Claims which
cannot be waived by law, including, without limitation, any rights you may have under applicable workers’ compensation laws and
your right, if applicable, to file or participate in an investigative proceeding of any federal, state or local governmental agency.
Nothing in this Agreement shall prevent you from filing, cooperating with, or participating in any proceeding or investigation before
the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Occupational
Safety and Health Administration, the Securities and Exchange Commission or any other federal government agency, or similar state or
local agency (“Government Agencies”), or exercising any rights pursuant to Section 7 of the National Labor Relations
Act. You further understand this Agreement does not limit your ability to voluntarily communicate with any Government Agencies or otherwise
participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other
information, without notice to the Company. While this Agreement does not limit your right to receive an award for information provided
to the Securities and Exchange Commission, you understand and agree that, you are otherwise waiving, to the fullest extent permitted
by law, any and all rights you may have to individual relief based on any Claims that you have released and any rights you have waived
by signing this Agreement. If any Claim is not subject to release, to the extent permitted by law, you waive any right or ability to
be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party
action or proceeding based on such a Claim in which any of the Company Parties is a party. This Agreement does not abrogate your existing
rights under any Company benefit plan or any plan or agreement related to equity ownership in the Company; however, it does waive, release
and forever discharge Claims existing as of the date you execute this Agreement pursuant to any such plan or agreement.


 


12.            Indemnification.
The Company hereby confirms its obligation, and otherwise agrees, to hold you harmless and indemnify
you in respect of your serving or having served as an officer, director, employee or agent of the Company, or one or more of its subsidiaries,
or at the request of the Company as an officer, director, employee or agent of another company, corporation, partnership, limited liability
company, joint venture, trust or other enterprise, to the fullest extent authorized or permitted by applicable law in effect on the date
hereof and as may be amended from time to time, but not for fraudulent or dishonest acts or omissions.

13.            Your
Acknowledgments and Affirmations / Effective Date of Agreement. You acknowledge that you are
knowingly and voluntarily waiving and releasing any and all rights you may have under the ADEA, as amended. You also acknowledge and agree
that you have been paid for all time worked, have received all the leave, leaves of absence and leave benefits and protections for which
you are eligible, and have not suffered any on-the-job injury for which you have not already filed a Claim. You affirm that all of the
decisions of the Company Parties regarding your pay and benefits through the date of your execution of this Agreement were not discriminatory
based on age, disability, race, color, sex, religion, national origin or any other classification protected by law. You affirm that you
have not filed or caused to be filed, and are not presently a party to, a Claim against any of the Company Parties. You further affirm
that you have no known workplace injuries or occupational diseases. You acknowledge and affirm that you have not been retaliated against
for reporting any allegation of corporate fraud or other wrongdoing by any of the Company Parties, or for exercising any rights protected
by law, including any rights protected by the Fair Labor Standards Act, the Family Medical Leave Act, or any related statute or local
leave or disability accommodation laws, or any applicable state workers’ compensation law. You further acknowledge and affirm that
you have been advised by this writing that: (a) your waiver and release do not apply to any rights or Claims that may arise after
the execution date of this Agreement; (b) you have been advised hereby that you have the right to consult with an attorney prior
to executing this Agreement; (c) you have been given twenty-one (21) days to consider this Agreement (although you may choose to
voluntarily execute this Agreement earlier and if you do you will sign the Consideration Period waiver below); (d) you have seven
(7) days following your execution of this Agreement to revoke this Agreement; and (e) this Agreement shall not be effective
until the date upon which the revocation period has expired unexercised (the “Effective Date”), which shall be the eighth
day after this Agreement is executed by you.


 


14.      No
Admission. This Agreement does not constitute an admission by the Company or by you of any wrongful
action or violation of any federal, state, or local statute, or common law rights, including those relating to the provisions of any
law or statute concerning employment actions, or of any other possible or claimed violation of law or rights.


 


15.            Breach.
You agree that upon any material and uncured breach by you of this Agreement, as determined by a court of competent jurisdiction, you
will forfeit all amounts paid or owing to you under this Agreement. The Company agrees that upon any material and uncured breach by the
Company of this Agreement, as determined by a court of competent jurisdiction, this Agreement shall be deemed null, void and unenforceable
by the Company. Notwithstanding the foregoing, and for the avoidance of doubt, all parties expressly reserve the right to seek specific
performance of the other party’s obligations under this Agreement. Further, you acknowledge that it may be impossible to fully assess
the damages caused by your violation of the terms of Sections 7 and 8 of this Agreement and further agree that any threatened or actual
violation or breach of those Sections of this Agreement may constitute immediate and irreparable injury to the Company. The Company acknowledges
that it may be impossible to fully assess the damages caused by its violation of the terms of Section 8 and further agree that any
threatened or actual violation or breach of this Section of this Agreement may constitute immediate and irreparable injury to you.
Accordingly, the parties therefore agree that any such breach of this Agreement is a material breach of this Agreement, and, in addition
to any and all other damages and remedies available to the non-breaching party upon a breach of this Agreement, the non-breaching party
shall be entitled to an injunction to prevent further violations or breaches of this Agreement. The parties further agree that if one
party is successful in whole or part in any legal or equitable action against the other under this Agreement, the failing party agrees
to pay all of the costs, including reasonable attorneys’ fees, incurred by the prevailing party in enforcing the terms of this Agreement.
