WAIVER AGREEMENT

This Waiver Agreement (this “Agreement”) is entered into this 29^th day of April, 2022 by and between WESTERN ALLIANCE BANK, an Arizona corporation (“Bank”), and ISPECIMEN INC., a Delaware corporation (“Borrower”) whose address is 450 Bedford Street, Lexington, Massachusetts 02420.

Recitals

A.            Among other indebtedness which may be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to, among other documents, that certain Loan and Security Agreement, dated as of August 13, 2021 by and between Borrower and Bank (as may be amended, modified, supplemented, or restated from time to time, the “Loan and Security Agreement”). Hereinafter, all indebtedness owing by Borrower to Bank shall be referred to as the “Indebtedness” and the Loan and Security Agreement and any and all other documents executed by Borrower in favor of Bank shall be referred to as the “Existing Documents.”

B.            Borrower has requested that Bank waive the Stated Event of Default (as defined below).

C.            Bank has agreed to waive the Stated Event of Default (as defined below), subject to the conditions and in reliance upon the representations and warranties set forth below.

Agreement

NOw, Therefore, in consideration of the foregoing recitals and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows:

1.            DEFINITIONS. Capitalized terms used but not defined in this Agreement shall have the meanings given to them in the Loan and Security Agreement.

2.            WAIVER. Bank hereby waives Borrower’s existing default under the Loan and Security Agreement by virtue of Borrower’s failure to comply with the Maximum Trailing Three- Month EBDA Deviation covenant set forth in Section 6.8(a) thereof for the trailing three (3) month period ending March 31, 2022 (the “Stated Event of Default”). Bank’s waiver of the Stated Event of Default shall apply only to the foregoing specific period. Borrower hereby acknowledges and agrees that except as specifically provided herein, nothing in this section or anywhere in this Agreement shall be deemed or otherwise construed as a waiver by Bank of any of its rights and remedies pursuant to the Loan Documents, applicable law or otherwise.

3.            CONSISTENT CHANGES. The Existing Documents are each hereby amended wherever necessary to reflect the changes described above.

4.            CONTINUING VALIDITY. Borrower understands and agrees that in modifying the existing Indebtedness, Bank is relying upon Borrower’s representations, warranties, and agreements, as set forth in the Existing Documents. Except as expressly modified pursuant to this Agreement, the terms of the Existing Documents remain unchanged and in full force and effect. Bank’s agreement to modifications to the existing Indebtedness pursuant to this Agreement in no way shall obligate Bank to make any future modifications to the Indebtedness. Nothing in this Agreement shall constitute a satisfaction of the Indebtedness. It is the intention of Bank and Borrower to retain as liable parties all makers and endorsers of Existing Documents, unless the party is expressly released by Bank in writing. No maker, endorser, or guarantor will be released by virtue of this Agreement. The terms of this paragraph apply not only to this Agreement, but also to any subsequent loan and security modification agreements.

5.             RELEASE BY BORROWER:

5.1            FOR GOOD AND VALUABLE CONSIDERATION, Borrower hereby forever relieves, releases, and discharges Bank and its present or former employees, officers, directors, agents, representatives, attorneys, and each of them, from any and all claims, debts, liabilities, demands, obligations, promises, acts, agreements, costs and expenses, actions and causes of action, of every type, kind, nature, description or character whatsoever, whether known or unknown, suspected or unsuspected, absolute or contingent, arising out of or in any manner whatsoever connected with or related to facts, circumstances, issues, controversies or claims existing or arising from the beginning of time through and including the date of execution of this Agreement (collectively “Released Claims”). Without limiting the foregoing, the Released Claims shall include any and all liabilities or claims arising out of or in any manner whatsoever connected with or related to the Loan Documents, the recitals hereto, any instruments, agreements or documents executed in connection with any of the foregoing or the origination, negotiation, administration, servicing and/or enforcement of any of the foregoing.

5.2            In furtherance of this release, Borrower expressly acknowledges and waives any and all rights under Section 1542 of the California Civil Code, which provides as follows:

“A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.” (Emphasis added.)

5.3            By entering into this release, Borrower recognizes that no facts or representations are ever absolutely certain and it may hereafter discover facts in addition to or different from those which it presently knows or believes to be true, but that it is the intention of Borrower hereby to fully, finally and forever settle and release all matters, disputes and differences, known or unknown, suspected or unsuspected; accordingly, if Borrower should subsequently discover that any fact that it relied upon in entering into this release was untrue, or that any understanding of the facts was incorrect, Borrower shall not be entitled to set aside this release by reason thereof, regardless of any claim of mistake of fact or law or any other circumstances whatsoever. Borrower acknowledges that it is not relying upon and has not relied upon any representation or statement made by Bank with respect to the facts underlying this release or with regard to any of such party’s rights or asserted rights.

5.4            This release may be pleaded as a full and complete defense and/or as a cross-complaint or counterclaim against any action, suit, or other proceeding that may be instituted, prosecuted or attempted in breach of this release. Borrower acknowledges that the release contained herein constitutes a material inducement to Bank to enter into this Agreement, and that Bank would not have done so but for Bank’s expectation that such release is valid and enforceable in all events.

5.5            Borrower hereby represents and warrants to Bank, and Bank is relying thereon, as follows:

(a)            Except as expressly stated in this Agreement, neither Bank nor any agent, employee or representative of Bank has made any statement or representation to Borrower regarding any fact relied upon by Borrower in entering into this Agreement.

(b)            Borrower has made such investigation of the facts pertaining to this Agreement and all of the matters appertaining thereto, as it deems necessary.

(c)            The terms of this Agreement are contractual and not a mere recital.

(d)            This Agreement has been carefully read by Borrower, the contents hereof are known and understood by Borrower, and this Agreement is signed freely, and without duress, by Borrower.

(e)            Borrower represents and warrants that it is the sole and lawful owner of all right, title and interest in and to every claim and every other matter which it releases herein, and that it has not heretofore assigned or transferred, or purported to assign or transfer, to any person, firm or entity any claims or other matters herein released. Borrower shall indemnify Bank, defend and hold it harmless from and against all claims based upon or arising in connection with prior assignments or purported assignments or transfers of any claims or matters released herein.

6.            CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER; REFERENCE PROVISION.
