 FOR
VALUE RECEIVED, AutoGenomics, Inc., a Delaware corporation (“Maker” or the “Company”), hereby promises to pay to the order of Tregale Group Ltd or registered assigns (“Holder”), the principal amount
of One Million Five Hundred Seventy One Thousand Fourteen Dollars, together with interest thereon at the rate of thirteen percent (13%) per annum (this “Note”), on or before July 9, 2011 (the “Maturity
Date”), subject to the terms and conditions set forth hereinbelow. This Note has been issued pursuant to, and is entitled to the benefits of, that certain Subscription Agreement with respect to this Note to which Maker and Holder are
parties (the “Agreement”). Capitalized terms not defined herein have the meaning assigned to them in the Agreement. 

This is one of a series of Subordinated Promissory Notes (collectively referred to herein as the “Subordinated Notes”),
all of like tenor, except as to the identifying number, principal amount and holder thereof. 
 1. Subordination.

 (a) Subordination to Senior Indebtedness. The indebtedness evidenced by this Note, and the payment of the principal
hereof and interest hereon, is wholly subordinated, junior and subject in right of payment, to the extent and in the manner hereinafter provided, to the prior payment of all Senior Indebtedness of the Company now outstanding or hereinafter incurred
as hereinafter provided. “Indebtedness” means the principal of, and premium, if any, and interest on (i) all indebtedness of the Company for monies borrowed from banks, trust companies, insurance companies and other financial
institutions, including commercial paper, letters of credit and accounts receivable sold or assigned by the Company to such institutions, (ii) all indebtedness of the Company for monies borrowed by the Company from other persons or entities
(excluding accrued expenses, trade payables, workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance, hedging obligations and surety bonds in the ordinary course of business), (iii) obligations of
the Company as lessee under leases of real or personal property, (iv) principal of, and premium, if any, and interest on any indebtedness or obligations of others of the kinds described above assumed or guaranteed in any manner by the Company,
(v) deferrals, renewals, extensions and refundings of any such indebtedness or 
  

 Page 1 

 
obligations described above, (vi) any balance deferred and unpaid of the purchase price of any property or services due more than six months after such property is acquired or such services
are completed, and (vii) any other indebtedness of the Company which the Company and the holders of more than 50% of the unpaid principal amount of the Subordinated Notes then outstanding may hereafter from time to time expressly and
specifically agree in writing shall constitute Indebtedness, if and to the extent any of the preceding items (other than letters of credit and hedging obligations) would appear as a liability upon a balance sheet of the specified person prepared in
accordance with GAAP. “Senior Indebtedness” means any Indebtedness designated by the Company as ranking senior to the Subordinated Notes, but not to exceed at any one time outstanding the sum of $4.0 million plus the aggregate
amount of Indebtedness outstanding as of the date hereof. Notwithstanding the foregoing, “Senior Indebtedness” shall not include indebtedness of the Company evidenced by the other Subordinated Notes, which shall rank equally and ratably
with this Note. 
 (b) Approval Required to Incur Additional Indebtedness. The incurrence by the Company of any
additional Indebtedness must be approved by the holders representing 75% of the aggregate principal amount of the then outstanding Notes; provided, however, that without the consent of any of the holders of the Notes, the Company may
incur (i) equipment financing, receivables-based financing and other unsecured Indebtedness, in an aggregate amount and/or aggregate borrowing capacity not to exceed $4.0 million at any one time outstanding, including any refinancings or
replacements thereof, and (ii) refinancings of all Indebtedness now outstanding. 
 (c) Rights of Holders
Unimpaired. The provisions of this Section 1 are, and are intended solely, for the purposes of defining the relative rights of the holders of the Subordinated Notes and the holders of Senior Indebtedness and nothing in this Section 1
shall impair, as between the Company and any holders of the Subordinated Notes, the obligation of the Company, which is unconditional and absolute, to pay to the holders of the Subordinated Notes the principal thereof, in accordance with the terms
of the Subordinated Notes, nor shall anything herein prevent any holders of the Subordinated Notes from exercising all remedies otherwise permitted by applicable law or hereunder upon default, subject to the rights set forth above of holders of
Senior Indebtedness to receive cash, property or securities otherwise payable or deliverable to the holders of the Subordinated Notes. 

2. Repayment of the Subordinated Notes. 

(a) Repayment at the Maturity Date. On the Maturity Date, the Company shall repay all, but not less than all, of the outstanding
principal amount of the Subordinated Notes, and all accrued and unpaid interest thereon, by mailing a corporate check in such amount payable to each Holder at such Holder’s address of record as contained herein or on file with the Company
pursuant to notice given as provided herein no later than ten (10) business days after the Maturity Date.
