PROMISSORY NOTE

$1,000,000.00 Worcester, Massachusetts

June 19, 2015

FOR VALUE RECEIVED Arrhythmia Research Technology, Inc., a corporation duly organized and validly existing under the laws of the State of Delaware having a principal place of business at 00 Xxxxxx Xxxxxxx, Xxxxxxxxx, Xxxxxxxxxxxxx 00000 and Micron Products Inc., a corporation duly organized and validly existing under the laws of the Commonwealth of Massachusetts having a principal place of business at 00 Xxxxxx Xxxxxxx, Xxxxxxxxx, Xxxxxxxxxxxxx 00000 (each and collectively, the “Borrower”) jointly and severally promise to pay to the order of UniBank for Savings (with its successors, assigns and any future holder or holders of this Note being the “Lender”) at its offices at 00 Xxxxxx Xxxxxx, Xxxxxxxxxxxx, Xxxxxxxxxxxxx 00000 or at such other place as the Lender may from time to time designate in writing, the principal sum of One Million and 00/100 Dollars ($1,000,000.00), or the aggregate unpaid principal amount of all advances made by the Lender to the Borrower under terms hereinafter set forth, whichever is less, in lawful money of the United States, to pay interest on each advance at a variable per annum rate equal to the Interest Rate (as hereafter defined), unless the Default Rate is in effect in which event the Interest Rate shall be the Default Rate. All advances shall be due and payable as set forth herein, but if not sooner paid, this Note and all amounts due hereunder shall be due and payable on June 19, 2021 (said date as the same may be extended from time to time in the Lender’s discretion, being the “Maturity Date”), without notice or demand.

This Note evidences the Borrower’s indebtedness under the $1,000,000 Equipment Line of Credit made by the Bank to the Borrower of even date herewith as defined in the Loan and Security Agreement among the Borrower and the Bank dated March 29, 2013 (as the same may be amended or modified from time to time, the “Loan Agreement”), incorporated herein by reference (the “2015 Equipment Line of Credit”).

Subject to the terms and conditions set forth herein and in the Loan Agreement, the Borrower may request advances and borrow funds under the 2015 Equipment Line of Credit during the period from the date hereof until the earlier of: (i) June 19, 2016 or (ii) the date upon which the amount of all advances under this Note are equal to the face amount of this Note (such date as it may be extended in writing from time to time, in the Bank’s sole discretion, being referred to herein as the “2015 Equipment Conversion Date”). The Borrower’s privilege to

-14-

Exhibit 10.61

request advances and borrow funds under the 2015 Equipment Line of Credit shall terminate on the 2015 Equipment Conversion Date or, at the Bank’s option, an earlier Default or Event of Default. The aggregate amount of all advances advanced under the 2015 Equipment Line of Credit shall not exceed $1,000,000.00. Advances which are repaid may not be reborrowed. Should the amount of said advances at any time exceed the maximum amount permitted herein, the Borrower shall be obligated to immediately pay to the Bank the amount of such excess together with accrued and unpaid interest.

Interest on the outstanding principal of all advances hereunder shall be due and payable commencing one month from the date hereof and continuing monthly thereafter on the same day or last day, whichever shall first occur, of each succeeding month (each a “Payment Date”) until the 2015 Equipment Conversion Date.

Commencing with the first Payment Date after the 2015 Equipment Conversion Date, principal and interest shall be due and payable in consecutive monthly installments the number of which shall be equal to the number of months remaining between the 2015 Equipment Conversion Date and the Maturity Date and of which all but the last (the “Final Payment”) shall be in such amount as is necessary to amortize the outstanding principal balance of this Note with interest thereon at the rate applicable from time to time hereunder based upon an assumed direct reduction amortization schedule equal to six (6) years from the date of this Note. Each such monthly installment of principal and interest shall be subject to adjustment by the Lender from time to time in order to insure that payments are sufficient to properly amortize the then outstanding principal balance of this Note with interest thereon based upon the applicable assumed amortization schedule and changes in the rate of interest applicable from time to time to the principal balance of this Note. The Lender may adjust any monthly installment upon written notice to the Borrower if a failure to so adjust would result in less than the total amount of all accrued interest due being paid on any Payment Date (as hereafter defined).

The first of said consecutive monthly payments of principal and interest shall be due and payable on the first Payment Date after the 2015 Equipment Conversion Date and the remainder of said monthly payments shall be due on the same day or last day, whichever shall first occur, of each succeeding month thereafter (each a “Payment Date”). The Final Payment shall be in an amount equal to the then outstanding principal balance of this Note plus all accrued and unpaid interest and all other amounts owing hereunder. The Final Payment, unless sooner paid, shall be due and payable on the Maturity Date, without notice or demand.

This Note has been executed and delivered subject to the following additional terms and conditions:

1. Definitions. For purposes of this Note, the following terms shall have the following meanings:

1.1 “Banking Day” means any day other than a Saturday or Sunday, or other day on which commercial banks in the Commonwealth of Massachusetts are authorized or required to close under the laws of the Commonwealth of Massachusetts.

-15-

Exhibit 10.61

2. Interest Rate. Except as hereinafter provided, the outstanding principal balance of this Note shall bear interest at a fluctuating per annum rate of interest equal to the Prime Rate plus one quarter of one percent (0.25%) until the 2015 Equipment Conversion Date.

For all purposes of this Note, the Lender’s written notice or

-17-

Exhibit 10.61

statement to the Borrower of the applicable rate of interest shall be conclusive and binding absent manifest error.

3. Advances, Notice Of Borrowing.

3.1 When the Borrower desires to borrow hereunder, it shall give the Lender notice specifying the date of the proposed borrowing (which shall be a Banking Day) and the amount to be borrowed. If any advance is made, the Lender shall record on the books and records of the Lender an appropriate notation evidencing such advance, each repayment on account of the principal thereof and the amount of interest paid; and the Borrower authorizes the Lender to maintain such records or make such notations and agrees that the amount shown on the books and records as outstanding from time to time shall constitute the amount owing to the Lender pursuant to this Note, absent manifest error. Amounts borrowed under this Note may not be reborrowed. Unless a Default or an Event of Default occurs, the Borrower may borrow and repay under this Note; provided, however, that: (i) each request by the Borrower for an advance hereunder shall be accompanied by an invoice evidencing the price and specifications of the equipment being purchased; (ii) at no time shall the outstanding principal balance of this Note exceed an amount equal to the face amount of this Note minus the aggregate amount of all Open Credits (the “2015 Equipment Maximum Availability”); (iii) at no time shall advances be requested which would cause the outstanding principal balance of this Note to exceed the 2015 Equipment Maximum Availability; (iv) all outstanding principal plus accrued and unpaid interest shall be paid in full on the Maturity Date; and (v) any privilege to request advances hereunder shall terminate on the 2015 Equipment Conversion Date.

3.2 [Intentionally omitted].

3.3 Any advance hereunder shall not exceed eighty percent (80%) of the invoice amount of the equipment being purchased with the proceeds of the 2015 Equipment Line of Credit.

3.4 The making of any advances by the Lender to the Borrower under the 2015 Equipment Line of Credit in excess of the 2015 Equipment Maximum Availability is for the Borrower’s benefit and does not in any way effect the unconditional obligation of the Borrower to repay such advances under the terms of this Note and the other applicable Loan Documents. Without limiting any other rights available to the Lender under the Loan Documents, the Borrower agrees to pay to the Lender upon DEMAND (whether or not an Event of Default exists) the principal balance of the 2015 Equipment Line of Credit outstanding in excess of the 2015 Equipment Maximum Availability together with all accrued and unpaid interest.

4. Interest Rate/Payments.

-18-

Exhibit 10.61

4.1. Interest Rate, Payment of Interest. So long as no Event of Default has occurred and subject to the terms hereof, each advance hereunder shall bear interest at the interest rate called for and calculated pursuant to the terms of this Note.

4.2. Accounts; Records. The Lender is authorized (but not required) to charge principal and interest and all other amounts due under this Note to any account of any Borrower with the Lender when and as it becomes due. All advances made by the Lender to the Borrower shall be evidenced by an appropriate notation on the books and records of the Lender, which records shall reflect each repayment on account of the principal thereof, and the amount of interest paid; and the Borrower authorizes the Lender to maintain such records or make such notations and agrees that the amount shown on the books and records of the Lender, as outstanding from time to time shall constitute the amount owing to the Lender pursuant to this Note, absent manifest error; provided, however, that the failure by the Lender to make any such notation with respect to any advance or payment shall not limit or otherwise affect the obligations of the Borrower hereunder.

4.3 Additional Payments. If the Lender in its reasonable judgment determines that the effect of an applicable law or government regulation, guideline or order or the interpretation thereof by any governmental authority charged with the administration thereof (such as, for example, a change in official reserve requirements which the Lender is required to maintain in respect of loans or deposits or other funds procured for funding such loans) is to increase the cost to the Lender of making or continuing a Loan hereunder or to reduce the amount of any payment of principal or interest receivable by the Lender thereon, then the Borrower shall pay to the Lender on demand such additional amounts as the Lender may determine in its sole and absolute discretion, to be required to compensate the Lender for such additional costs or reduction. Any additional payment under this section will be computed from the effective date at which such additional costs have to be borne by the Lender. A certificate as to any additional amounts payable pursuant to this section setting forth the basis and method of determining such amounts shall be conclusive, absent manifest error, as to the determination by the Lender set forth therein if made reasonably and in good faith. The Borrower shall pay any and all amounts so certified to it by the Lender within ten (10) days of receipt of such certificate.

5. 360 Day Year / Default Rate. All computations of interest under this Note shall be made on the basis of a three hundred sixty (360) day year and the actual number of days elapsed. To the extent allowed by applicable law, after the occurrence of any Event of Default, after the Maturity Date or after judgment has been rendered on this Note, all outstanding principal and unpaid interest shall bear, until paid, interest at a rate per annum equal to four (4.000) percentage points greater than the Interest Rate called for and calculated pursuant to the terms of this Note (the “Default Rate”).

6. Late Charge. If a regularly scheduled payment is fifteen (15) days or more late, Borrower will be charged five percent (5.000%) of the unpaid portion of the regularly scheduled payment or twenty five dollars ($25.00), whichever is greater. If the Lender demands payment of

-19-

Exhibit 10.61

the Loan and the Borrower does not pay the Loan within fifteen (15) days after the Lender’s demand, the Borrower will be charged either five percent (5.000%) of the unpaid principal plus accrued unpaid interest or twenty five dollars ($25.00), whichever is greater.

7. Expenses. The Borrower further promises to pay to the Lender, as incurred, and as an additional part of the unpaid principal balance, all costs, expenses and reasonable attorneys’ fees (which may include, without limitation, the allocable cost of the Lender’s internal legal counsel) incurred: (a) in the protection, modification, collection, defense or enforcement of all or part of this Note or any guaranty hereof or any other Loan Document; (b) in the foreclosure or enforcement of any mortgage or security interest which may now or hereafter secure either the debt hereunder or any guaranty thereof; (c) with respect to any action taken to protect, defend, modify or sustain the lien of any such mortgage or security agreement; (d) with respect to any litigation or controversy arising from or connected with this Note or any mortgage or security agreement or collateral which may now or hereafter secure this Note; or (e) with respect to any act to protect defend, modify, enforce or release any of its rights or remedies with regard to, or otherwise effect collection of, any collateral which may now or in the future secure this Note or with regard to or against the Borrower or any endorser, guarantor or surety of this Note.

8. Prepayment. The Borrower may prepay this Note in whole or in part, at any time, without penalty or premium.

9. Mandatory Prepayment / Application of Payments.

9.1. The Borrower shall be required to prepay ON DEMAND all advances made under this Note to the extent the aggregate of all such advances exceeds the amounts permitted hereunder. In addition the Borrower shall pay, if applicable, charges incurred pursuant to the terms hereof.

9.2. All payments, including any prepayments shall, at the option of the Lender, be applied first to interest on the unpaid principal of all advances due under this Note, and then to the payment of all fees, costs, and expenses incurred by the Lender or owing to the Lender by the Borrower arising out of the loan transaction evidenced by this Note which have not been paid or reimbursed to the Lender, and then to the balance on account of the principal due under this Note.

Prepayments of principal (whether voluntary or involuntary) shall be applied to unpaid principal installments under this Note in inverse order of their maturity and shall not affect the obligation to pay regular installments due hereunder until the entire indebtedness is paid in full.

10. Loan Agreement. This Note has been executed and delivered in accordance with the Loan Agreement which sets forth further terms and conditions upon which the entire unpaid principal hereof and all interest hereon may become due and payable prior to the Maturity Date, and generally as to further rights of the Lender and duties of the Borrower with respect hereto. Capitalized terms not defined herein which are defined terms in the Loan Agreement shall have

-20-

Exhibit 10.61

the meanings set forth therein. No reference to the Loan Agreement or other Loan Documents or to any provision thereof shall affect or impair the absolute and unconditional obligation of the Borrower to pay principal or interest or other amounts owing under this Note.

11.1. The happening of any of the following events or conditions shall constitute an “Event of Default” under this Note:

11.1.1. Failure to make any payment of principal or interest or any sum due under this Note or any other promissory note or instrument made by the Borrower or any one or more of them in favor of the Lender; or

11.1.2. Failure by any Borrower to observe or perform any covenant contained herein; or

11.1.3 A default or the occurrence of an event of default in any other Loan Document including, without limitation, an Event of Default as defined in the Loan Agreement.

11.2. Upon and after the occurrence of a Default or an Event of Default, the availability of advances hereunder shall, at the option of the Lender, be deemed to be automatically terminated. Upon and after an Event of Default, at the option of the Lender, the whole of the indebtedness evidenced by this Note, including principal and interest, and all other amounts which may be or become due or owing by the Borrower to the Lender shall, at the option of the Lender, immediately become due and payable without presentment, demand, protest, notice of protest, or other notice of dishonor of any kind, all of which are hereby expressly waived by the Borrower.

12. Waivers, Consent to Jurisdiction. Each Borrower agrees that no delay or failure on the part of the Lender in exercising any power, privilege, remedy, option or right hereunder shall operate as a waiver thereof or of any other power, privilege, remedy or right; nor shall any single or partial exercise of any power, privilege, remedy, option or right hereunder preclude any other or future exercise thereof or the exercise of any other power, privilege, remedy, option or right. The rights and remedies expressed herein are cumulative, and may be enforced successively, alternately, or concurrently and are not exclusive of any rights or remedies which holder may or would otherwise have under the provisions of all applicable laws, and under the provisions of all agreements between the Borrower and the Lender.

Each Borrower hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note.

Each Borrower hereby waives such rights as it may have to notice and/or hearing under any applicable federal or state laws pertaining to the exercise by Lender of such rights as the Lender may have regarding the right to seek prejudgment remedies and/or deprive Borrower of or affect the use of or possession or enjoyment of Borrower’s property prior to the rendition of a final judgment against the Borrower. Each Borrower further waives any right it may have to require Lender to provide a bond or other security as a precondition to or in connection with any prejudgment remedy sought by Lender, and waives any objection to the issuance of such prejudgment remedy based on any offsets, claims, defenses or counterclaims to any action brought by the Lender.

EACH BORROWER AND LENDER MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR ANY OTHER DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR LENDER TO MAKE THE LOAN AND ACCEPT THIS NOTE.

Each Borrower hereby agrees that the following courts: State Court - Any state or local court of the Governing State; Federal Court - United States District Court for the District of the Governing State; or at the option of Lender, any court in which Lender shall initiate legal or equitable proceedings and which has subject matter jurisdiction over the matter in controversy, shall have exclusive jurisdiction to hear and determine any claims or disputes between Borrower and Lender pertaining directly or indirectly to this Note or to any matter arising in connection with this Note. Each Borrower expressly submits and consents in advance to such jurisdiction in any action or proceeding commenced in such courts, hereby waiving personal service of the summons and complaint, or other process or papers issued therein, and agreeing that service of such summons and complaint, or other process or papers, may be made by registered or certified mail addressed to Borrower at the address set forth herein.

Exhibit 10.61

13. Maximum Permissible Interest Rate. The Borrower shall not be obligated to pay and the Lender shall not collect interest at a rate higher than the maximum permitted by law or the maximum that will not subject the Lender to any civil or criminal penalties. If, because of the acceleration of maturity the payment of interest in advance or any other reason, the Borrower is required, under the provisions of any Loan Document or otherwise, to pay interest at a rate in excess of such maximum rate, the rate of interest under such provisions shall immediately and automatically be reduced to such maximum rate and any payment made in excess of such maximum rate, together with interest thereon at the rate provided herein from the date of such payment, shall be immediately and automatically applied to the reduction of the unpaid principal balance of this Note as of the date on which such excess payment was made. If the amount to be so applied to reduction of the unpaid principal balance exceeds the unpaid principal balance, the amount of such excess shall be refunded by the Lender to the Borrower.

Section 341. No such pledge or enforcement thereof shall release the Lender from its obligations under any of the Loan Documents.

15.2. The Lender shall have the unrestricted right at any time or from time to time, and without any Borrower’s consent, to sell, assign, endorse, or transfer all or any portion of its rights and obligations hereunder to one or more lenders or other entities (each an “Assignee”), and each Borrower agrees that it shall execute, or cause to be executed such documents including without limitation, amendments to this Note and to any other documents, instruments, and agreements executed in connection herewith as the Lender shall deem necessary to effect the foregoing. In addition, at the request of the Lender or any such Assignee, the Borrower shall issue one or more new promissory notes, as applicable, to any such Assignee and, if the Lender has retained any of its rights and obligations hereunder following such assignment, to the Lender, which new promissory notes shall be issued in replacement of, but not in discharge of, the liability evidenced by the note held by the Lender prior to such assignment and shall reflect the amount of the respective commitments and loans held by such Assignee and the Lender after giving effect to such assignment. Upon the execution and delivery of appropriate assignment documentation, amendments, and any other documentation required by the Lender in connection with such assignment, and the payment by such Assignee of the purchase price agreed to by Lender and such Assignee, such Assignee shall be a party to this Note and shall have all of the rights and obligations of the Lender hereunder (and under any and all other guaranties, documents, instruments and agreements executed in connection herewith) to the extent that such rights and obligations have been assigned by the Lender pursuant to the assignment documentation between the Lender and such Assignee, and the Lender shall be released from its obligation hereunder and thereunder to a corresponding extent.

16. Setoff. Each Borrower hereby grants to the Lender a lien, security interest, and a right of setoff as security for all of the Obligations, upon and against all deposits, credits, collateral, and property of any Borrower, now or hereafter in the possession, custody, safekeeping, or control of the Lender or any entity under the control of the Lender, or in transit to any of them. At any time, without demand or notice, the Lender may set off the same or any part thereof and apply the same to any liability or obligation of the Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE THE LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS, OR OTHER PROPERTY OF EACH BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY, AND IRREVOCABLY WAIVED. The Lender shall not be required to marshal any present or future security for, or guarantees of, the Obligations or to resort to any such security or guarantee in any particular order and each Borrower waives, to the fullest extent that it lawfully can: (a) any right it might have to require the Lender to pursue any particular remedy before proceeding against them; and (b) any right to the benefit of, or to direct the application of the proceeds of any collateral until the Obligations are paid in full.

17. Security. This Note and all other Obligations are secured by all assets of each Borrower whenever arising or created in accordance with the terms of the Loan Agreement and all other documents which create or perfect security interests in assets or properties of any Borrower. This Note and all other Obligations are further secured by that certain specific equipment of the Borrower to be purchased with the proceeds of the Loan.

18. Extension of Relevant Dates. In the event that any relevant date upon which a payment is due and payable under this Note or which affects any interest rate option of the Borrower shall fall on a date which is not a Banking Day, then any such relevant date may be extended by the Lender in accordance with the Modified Following Banking Day Convention and interest shall continue to accrue, and the relevant due dates shall also be extended, for the period of that extension at the interest rate or rates then in effect. For purposes hereof, the “Modified Following Banking Day Convention” shall mean the convention for adjusting any relevant date if it would otherwise fall on a day that is not a Banking Day. When used in conjunction with the term, “Modified Following Banking Day Convention”, and a date, such term shall mean that an adjustment will be made if that date would otherwise fall on a day that is not a Banking Day so that the date will be the first following day that is a Banking Day.

Notwithstanding anything to the contrary hereinabove contained, if application of the Modified Following Banking Day Convention would cause any payment due under the terms of this Note to be due and payable in a calendar month which differs from the month in which the payment would otherwise have been due, then, at the Lender’s option, the Modified Following Banking Day Convention shall not apply and such payment shall be due and payable on the immediately preceding Banking Day.

19. Joint and Several Obligations; Miscellaneous. This Note and all representations and covenants of the Borrower herein shall be the joint and several obligation of the Borrower
