			US $_______October_____, 2016
		

		
			Subject to the terms and conditions of this Amended and Restated Subordinated Promissory Note (this “Note”), for value received, the undersigned Arrhythmia Research Technology, Inc., a Delaware corporation (the “Company”) with an address of 25 Sawyer Passway, Fitchburg, MA 01420, hereby promises to pay ________________________________________________ (the “Holder”), the principal amount of _______________________________________, with interest thereon, as provided herein.  This Note supersedes and replaces that certain note dated December 19, 2013 by the undersigned to the Holder.
		

		
			This Note is one of a series of Subordinated Notes issued by the Company pursuant to a private placement conducted in accordance with Regulation D under the Securities Act of 1933, as amended, issued as of December 19, 2013 (the “Original Issue Date” and, in the case of any Note issued after the Original Issue Date, the “Issue Date”) all of like tenor, except as to the principal amount and holder thereof.  The following is a statement of the rights of the Holder of this Note and the terms and conditions to which this Note is subject, and to which the Holder, by acceptance of this Note, agrees:
		

		
			1.Principal Repayment.  The outstanding principal amount of this Note shall be due and payable on the Maturity Date (as hereinafter defined), unless this Note has been prepaid in accordance with the terms set forth below.
		

		
			2.Interest.  As of the Original Issue Date through December 18, 2014, interest accrued on the unpaid principal of this Note at a simple interest rate equal to ten percent (10%) per annum.  From December 19, 2014 through December 18, 2016, interest accrued on the unpaid principal of this Note at a simple interest rate equal to twelve percent (12%) per annum.  From December 19, 2016 through the Maturity Date,  interest shall accrue on the unpaid principal of this Note at a simple interest rate equal to ten percent (10%) per annum, and until the interest and principal hereunder shall have been repaid in full. Interest only shall be payable in cash on a quarterly basis on or before the fifth business day following the end of each calendar quarter (or portion thereof) hereafter (the “Quarterly Payment Date”) unless the Company shall have, prior to the Quarterly Payment Date, received written notice from the Senior Lender (as defined below) deferring such quarterly interest payment (the “Deferral Notice”).  In the event the Company receives a Deferral Notice it shall provide a copy thereof to the Holder and such quarterly interest payment (and any subsequent quarterly interest payment which may occur) shall be deferred, and no default hereunder shall be deemed to occur hereunder, until the Company’s receipt from the Senior Lender of a notice releasing such quarterly interest payment (and, if applicable, any subsequent quarterly interest payment also released) (the “Release Notice”). Upon the Company’s receipt of a Release Notice, the Company shall pay to the Holder the quarterly interest payment(s) so released on or before the fifth business day thereafter.  All computations of interest hereunder shall be made on the basis of a year of 365 days based on the actual number of days elapsed (including the first day but excluding the last day) and only on the principal amount hereof or of any such portion which is outstanding.  Should the rate of interest as calculated under this Note exceed that allowed by law, the applicable rate of interest will be the maximum rate of interest allowed by applicable law.
		

		
			3.Maturity Date.  The principal amount of this Note, together with all interest accrued thereon, shall be due and payable by 5:00 p.m. Eastern Standard Time on December 31, 2018 (the “Maturity Date”).

			5.Subordination.  By acceptance of this Note, the Holder, for itself and its successors and permitted assigns, acknowledges and agrees for the benefit of the Company and its senior lender, UniBank for Savings (together with its successors and assigns, the “Senior Lender”) that, notwithstanding any provision of this Note to the contrary, the payment of any interest, principal or any other amounts under this Note, and the performance by the Company of its obligations hereunder, is and shall be expressly subordinated and junior in right of payment to the prior indefeasible payment in full of all Senior Indebtedness (as hereinafter defined), whether now existing or hereafter arising, and is hereby subordinated as a claim against the Company or any of the assets of the Company, whether such claim be in the event of any distribution of the assets of the Company, upon any reorganization or composition or bankruptcy, insolvency, receivership or other statutory or common law proceedings or arrangements involving the Company or the readjustment of its liabilities or any assignment for the benefit of creditors or any marshaling of its assets or liabilities or any general failure of the Company to pay its debts as they become due.

			6.Payment.  All payments with respect to this Note shall be made in lawful money of the United States of America at the address of the Holder set forth hereinabove or such other place as the Holder hereof may reasonably designate in writing to the Company.  Payment shall be credited first to the accrued interest then due and payable and the remainder applied to principal.
		

		
			7.No Security.  This Note is unsecured.
		

		
			8.Defaults and Remedies.  The entire unpaid principal of this Note shall become and be immediately due and payable upon written demand by the Holder, without any other notice or demand of any kind or any presentment or protest, if any one of the following events (each, an “Event of Default”) shall occur and be continuing at the time of such demand, whether voluntarily or involuntarily, or, without limitation, occurring or brought about by operation of law or pursuant to or in compliance with any judgment, decree or order of any court or any order, rule or regulation of any governmental body:
