Exhibit 10.3

SURETY AGREEMENT

THIS SURETY AGREEMENT (“Surety Agreement”) is made effective as of April 10, 2020 by AMBRELL CORPORATION, a Delaware corporation, INTEST SILICON VALLEY CORPORATION, a Delaware corporation, INTEST EMS, LLC, a Delaware limited liability company, and Temptronic Corporation, a Delaware corporation (individually and collectively, jointly and severally, the “Guarantor”) in favor of M&T Bank (together with its successors and assigns, “Bank”).

BACKGROUND

A.     Bank is entering into that certain Loan and Security Agreement dated of even date herewith with Guarantor, INTEST CORPORATION, a Delaware corporation (the “Borrower”) (as it may be further amended, supplemented or restated from time to time, the “Loan Agreement”).

B.     Bank is willing to extend the Loans to Borrower under the Loan Agreement, only if Guarantor agrees to guarantee and become surety for the full, prompt, complete and faithful payment and performance of all Obligations of Borrower subject to the terms and conditions of this Surety Agreement, and to execute and deliver this Surety Agreement.

C.     Guarantor will benefit directly and indirectly from the extension or continuation of such credit facilities to Borrower.

D.     Capitalized terms not otherwise defined in this Surety Agreement will have the meanings set forth in the Loan Agreement.

NOW, THEREFORE, for good and valuable consideration, and intending to be legally bound hereby, Guarantor irrevocably and unconditionally agrees as follows:

1.     Unlimited Continuing Guaranty and Suretyship Obligation. Guarantor guarantees to Bank and becomes a surety to Bank, for the Obligations. The liability of Guarantor hereunder is unlimited. THIS SURETY AGREEMENT IS A CONTINUING GUARANTY AND SURETYSHIP AGREEMENT AND SHALL CONTINUE IN FORCE UNTIL ALL OBLIGATIONS HAVE BEEN PAID OR SATISFIED IN FULL AS DETERMINED BY BANK AND BANK HAS NO FURTHER OBLIGATION OR COMMITMENT TO ADVANCE SUMS OR EXTEND ANY CREDIT FACILITY TO BORROWER. GUARANTOR EXPRESSLY AGREES THAT BORROWER MAY CREATE OR INCUR OBLIGATIONS AND MAY REPAY AND SUBSEQUENTLY CREATE OR INCUR OBLIGATIONS, ALL WITHOUT NOTICE TO GUARANTOR, AND GUARANTOR SHALL BE BOUND THEREBY. ALL ADVANCES TO AND BORROWINGS OF BORROWER FROM BANK SHALL CONSTITUTE ONE SINGLE OBLIGATION GUARANTEED BY GUARANTOR PURSUANT TO THE TERMS HEREOF.

2.     Costs and Expenses. Guarantor shall pay upon demand all costs and expenses incurred by Bank in connection with Bank interpreting, enforcing, protecting and/or preserving its rights or remedies hereunder and any amount thereof not paid promptly following demand therefor shall be added to the sum payable hereunder and shall bear interest at the Default Rate from the date of such demand until paid in full. If Bank employs counsel to enforce this Surety Agreement by suit or otherwise, Guarantor will reimburse Bank upon demand for all costs of suit and other expenses in connection therewith, whether or not suit is actually instituted, together with Bank’s reasonable attorney’s fees together with interest on any judgment obtained by Bank at such Default Rate, including interest at such Default Rate from and after the date of execution, judicial or foreclosure sale until actual payment is made to Bank of the full amount due Bank hereunder.

3.     Scope and Duration of Liability.

3.1     Primary Liability. The obligations of Guarantor hereunder are primary, absolute, independent, irrevocable and unconditional. Guarantor’s obligation to pay any of the Obligations is a guaranty of payment, not of collection. This agreement is an agreement of suretyship as well as of guaranty and without being required to proceed first against Borrower or any other person or entity, or against any other security for the Obligations, Bank may proceed directly against Guarantor upon the occurrence of an Event of Default.

3.2     Duration. This Surety Agreement shall remain in full force and effect until all of the Obligations are fully, finally and irrevocably paid, complied with and performed and until all sums received by Bank thereunder are no longer subject to rescission or repayment upon Bankruptcy, insolvency or reorganization of Borrower or Guarantor. If at any time a payment or payments by Borrower or Guarantor on any of the Obligations, or any part thereof, are subsequently invalidated, declared to be fraudulent or preferential, set aside or are required to be repaid to a trustee, receiver or any other person or entity under any bankruptcy act, state or federal law, common law or equitable cause, then to the extent of such payment or payments, the Obligations intended to be satisfied shall be revived and continued in full force and effect as if such payment or payments had not been made.

3.3     Remedies. Upon the occurrence of an Event of Default, Guarantor shall immediately pay, comply with and perform such of the Obligations as Bank shall direct, irrespective of whether the Obligations directed by Bank to be paid, complied with and performed by Guarantor are those which gave rise to the Event of Default.

4.    Unconditional Enforceability.

4.1     Enforceability. The obligations of Guarantor under this Surety Agreement shall be unconditional and irrevocable, irrespective of:

(A)     the genuineness, validity or enforceability of any of the Loan Documents;

(B)     any limitation of liability of Borrower or any other person or entity contained in the Loan Documents;

(C)     the existence of any security given to secure the Loan Documents;

(D)     any change in Borrower’s financial condition, operations, loan status or collateral position, or the impossibility or illegality of performance on the part of Borrower obligations under the Loan Documents;

-2-

(E)     any defense that may arise by reason of the incapacity or lack of authority of Borrower, any other guarantor or other person or entity or the failure of Bank to file or enforce a claim against the estate of Borrower in any bankruptcy or other proceedings; or

(F)     any other circumstances, occurrences or conditions, whether similar or dissimilar to any of the foregoing, which might otherwise constitute a legal or equitable defense, discharge or release of a guarantor or surety.

4.2     Acceleration. If Borrower or any other person or entity defaults under the Loan Documents and Bank is prevented from accelerating payment thereunder, either by operation of any bankruptcy laws or otherwise, Bank shall be entitled to receive from Guarantor, upon demand by Bank, the sums which would have otherwise been due and payable had such acceleration occurred.

5.     Consideration. Guarantor acknowledges and agrees (a) that it has received good and valuable consideration for guaranteeing the obligations of Borrower under this Surety Agreement, and (b) based upon Guarantor’s financial condition, Borrowers’ financial consideration and the reasonable likelihood that Borrower might default under its obligations to Bank and Guarantor would be compelled to perform under this Surety Agreement, Guarantor is not rendered insolvent by the execution of this Surety Agreement. Guarantor represents and warrants to Bank that, based upon Guarantor’s knowledge of and familiarity with, the financial condition and business operations of Borrower, Borrower’s business and operations are financially viable and Borrowers should be able to pay their debts and obligations as and when due in the ordinary course of business.

6.     Release/Modification/Information. Bank may at any time and from time to time, with or without consideration, release or discharge Guarantor, Borrower or any one or more other guarantors of or sureties for any or all of the Obligations, agree to the substitution, exchange or release of all or any part of the collateral securing the Obligations, obtain or receive any additional collateral or suretyship obligations securing the Loan Documents, and/or modify, amend, increase, extend, renew or supplement any of the Obligations or the Loan Documents, all without notice to or further consent from Guarantor. Except as may be expressly agreed to by Bank in writing, none of the foregoing actions shall in any way affect or diminish the liability of Guarantor under this Surety Agreement. Bank has no obligation or commitment of any kind to inform or advise Guarantor of any information, occurrences or events regarding Borrower or its financial condition, operations, loan status or collateral position, including, without limitation, any material adverse change in such financial condition, operations, loan status or collateral position. Guarantor acknowledges that it shall be solely responsible for keeping itself informed as to any of the foregoing matters.

7.     Subrogation. Guarantor hereby agrees that:

7.1     Subordination. Any and all rights of subrogation that Guarantor may have against Borrower or against any collateral or security for any of the Obligations, and any and all rights of contribution, indemnity and/or substitution that Guarantor may have against Borrower or any other guarantor or surety, shall be junior and subordinate to the Obligations, to any rights that Bank may have against Borrower, to all right, title and interest that Bank may have in any such collateral or security for the Obligations, and to any right Bank may have against such other guarantor or surety. Bank may use, sell or dispose of any item of collateral or security for the Obligations as it sees fit without regard to any subrogation rights Guarantor may have, and upon any such disposition or sale of such collateral or security any rights of subrogation that Guarantor may have with respect to such collateral or security shall terminate.

-3-

7.2     Limitations. Until the Obligations shall have been indefeasibly paid in full, Guarantor shall not take, or permit to be taken, any action to exercise (a) any right of subrogation arising in respect of the Obligations, (b) any right of contribution arising in respect of the Obligations that Guarantor may have against any other guarantor or surety of the Obligations, (c) any right to enforce any remedy which Bank now has or may hereafter have against Borrower, or (d) any benefit of, and any right to participate in, any security now or hereafter held by Bank. If any amount shall be paid to Guarantor on account of such subrogation or contribution rights at any time when all Obligations shall not have been paid in full, such amount shall be held in trust for Bank and shall forthwith be paid over to Bank to be credited and applied against the Obligations, whether matured or unmatured, in accordance with the terms of the Loan Documents.

8.     Representations. Guarantor represents and warrants to Bank that:

8.1     Valid Organization, Good Standing and Qualification.

8.2     Due Authorization; No Legal Restrictions.
