 Exhibit 10.13 
 UNSECURED SUBORDINATED PROMISSORY NOTE 
  

			
	$400,000.00 – Principal Amount	 	Issue Date – December 29, 2006

 1. Principal and Interest. For value received, IRVINE SENSORS CORPORATION, a Delaware
corporation (“Maker”), hereby promises to pay to the order of TIMOTHY LOONEY, an individual (“Payee”), whose address is 4306 Savannah, Parker, Texas, 75002, or such other address as the holder of this
Unsecured Subordinated Promissory Note (this “Note”) may designate in writing, the principal sum of $400,000.00, together with interest on the unpaid principal balance from time to time remaining at a rate per annum
(calculated on the basis of actual days elapsed, but computed as if each calendar year consisted of 360 days) which shall from day to day be equal to 11%. 
 2. Payment. The principal of and accrued interest on this Note shall be due and payable in full on the earlier of December 29, 2007, and the date the Senior Debt (hereinafter defined) is indefeasibly paid
in full. Payment shall be deemed made at the time the holder of this Note receives such payment, subject to the condition subsequent that any check or similar instrument is honored as drawn on sufficient funds. All amounts paid hereunder shall be
applied first to accrued and unpaid interest and then to principal. 
 3. Representations and Warranties. Maker represents and
warrants to Payee as follows: 
 (a) Existence, Etc. Maker is a corporation duly organized validly existing and in good standing under
the laws of the state of its organization and is duly qualified to do business and is in good standing in each other state where the failure to be so qualified and in good standing could reasonably be expected to have a material adverse effect on
the business, operations or condition (financial or otherwise) of Maker or on the ability of Maker to perform or comply with the terms and conditions of this note (such a material adverse effect being herein called a “Material Adverse
Effect”). 
 (b) Power and Authority. Maker has all requisite power and authority to own or lease its properties, to
conduct its business as now conducted and to execute, deliver and perform the Note. 
 (c) Authorization and Enforceability. The
execution, delivery and performance of the Note has been duly authorized by all necessary corporate action of Maker and requires no consent of any person or entity that has not been obtained, and the Note constitutes a valid and binding obligation
of Maker, enforceable in accordance with its terms, except as such enforceability may be limited by Debtor Relief Laws (hereinafter defined) and by general principles of equity. 
 (d) No Violation. The execution, delivery and performance of the Note does not and will not violate Maker’s charter, bylaws, or other
organizational documents, any laws applicable to Maker or any agreement to which Maker is a party or by which Maker is bound, except for violations of laws or agreements that could not reasonably be expected to have a 
  

 1 








 Material Adverse Effect. No consent or approval of any person or entity is required in connection with such execution,
delivery and performance, except as has been obtained and is in full force and effect. 
 (e) General. All financial statements,
reports and other information heretofore delivered by Maker to Payee, taken as a whole, do not contain any untrue statements of a material fact or omit to state any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. 
 4. Prepayment. Maker shall have the right to prepay all or any portion of
the principal hereof at any time without premium or penalty; provided, however, that with any prepayment Maker shall also pay all accrued but unpaid interest on the principal being prepaid. 
 5. Late Charge. If any payment of principal or interest hereunder is not paid when due, including upon acceleration hereof, interest under this
Note shall accrue from the date of the default until paid at a rate equal to the lesser of 18% per annum or the highest interest rate permitted by law (“Default Rate”). All payments of such late charges shall be made in
lawful money of the United States of America. 
 6. Subordination. Notwithstanding anything contained herein that may be to the
contrary, the payment of this Note and the rights and remedies of Payee and any other holder of this Note under this Note are subordinate to the payment of the Senior Debt, as defined in that certain Subordination Agreement of even date herewith,
among Payee, Longview Fund L.P. and Alpha Capital Anstalt, and are otherwise subject to such Subordination Agreement. 
 7. Event of
Default. Any one or more of the following events or occurrences shall constitute an event of default under this Note (“Event of Default”): 
 (a) Maker’s failure to pay any amount owed hereunder at the time and in the manner such payment is due, and such failure is not cured within ten (10) days after notice of such failure is given in accordance
with Paragraph 12 below. 
 (b) A breach by Maker of any other provision of this Note, and such breach is not cured within twenty
(20) days after notice of such breach is given in accordance with Paragraph 12 below. 
 (c) Maker shall (i) admit in writing its
inability to pay or otherwise fail to pay its debts generally as they become due, (ii) voluntarily seek consent to, or acquiesce in the benefit or benefits of any Debtor Relief Law, or (iii) be made the subject of any proceeding provided
for by any Debtor Relief Law that could suspend or otherwise affect any of the rights of the holder hereof and such proceeding should continue for sixty (60) days without dismissal or discharge. As used herein, “Debtor Relief
Laws” means the United States Bankruptcy Code, 11 U.S.C.§§ 101, et seq., and all other applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement, receivership, insolvency, reorganization or similar
debtor relief laws from time to time in effect affecting the rights of creditors generally. 
 (d) The nonpayment when due of any material
indebtedness exceeding $250,000 owed by Maker (including the Senior Debt), or the occurrence of any event under any document or instrument evidencing, securing, or executed in connection with any such indebtedness which could give the holder thereof
the right to declare such indebtedness or any part thereof due prior to its scheduled maturity.

 UPON THE OCCURRENCE OF AN EVENT OF DEFAULT, PAYEE MAY, SUBJECT TO THE SUBORDINATION PROVISIONS SET FORTH IN
PARAGRAPH 6, (A) BY WRITTEN NOTICE TO MAKER, DECLARE THE ENTIRE UNPAID PRINCIPAL BALANCE OF THIS NOTE, TOGETHER WITH ANY ACCRUED AND UNPAID INTEREST, IMMEDIATELY DUE AND PAYABLE, AND (B) PROCEED TO PROTECT AND ENFORCE ITS RIGHTS
EITHER BY SUIT IN EQUITY AND/OR BY ACTION AT LAW, OR BY OTHER APPROPRIATE PROCEEDINGS, WHETHER FOR THE SPECIFIC PERFORMANCE OF ANY AGREEMENT CONTAINED IN THIS NOTE OR IN AID OF THE EXERCISE OF ANY POWER OR RIGHT GRANTED BY THIS NOTE OR TO ENFORCE
ANY OTHER LEGAL OR EQUITABLE RIGHT OF THE PAYEE UNDER THIS NOTE. 
 8. Cumulative Rights. No delay on the part of Payee in the
exercise of any power or right under this Note shall operate as a waiver thereof, nor shall a single or partial exercise of any other power or right. Enforcement by the Payee of any right or remedy for the payment hereof shall not constitute any
election by it of remedies so as to preclude the exercise of any other remedy available to it. 
 9. Waivers. Maker, for itself and
its legal representatives, successors and assigns, expressly waives presentment, protest, demand, notice of dishonor, notice of nonpayment, notice of maturity, notice of protest, presentment for the purpose of accelerating maturity, and diligence in
collection. 
 10. Fees and Expenses. Maker shall pay all expenses and costs, including reasonable fees and out-of-pocket expenses of
attorneys (including Payee’s attorneys) and expert witnesses and costs of investigation, incurred by Payee (a) in connection with the negotiation of this Note and the related agreements between Payee and Maker, which are being executed
contemporaneously herewith, or (b) in connection with efforts to collect any amount due under this Note, including those incurred in post-judgment collection efforts and in any bankruptcy proceeding (including any action for relief from the
automatic stay of any bankruptcy proceeding). For purposes of this Paragraph, attorney’s out-of-pocket expenses shall include, but are not limited to, support staff costs, costs of preparing for litigation, computerized research, telephone and
facsimile transmission expenses, mileage, deposition costs, postage, duplicating, process service, videotaping and similar costs and expenses. 
 11. Modifications in Writing. No waiver or modification of any of the terms or provisions of this Note shall be valid or binding unless set forth in a writing signed by Maker and Payee, and then only to the extent therein
specifically set forth. 
 12. Notices. All notices required or permitted hereunder shall be in writing and shall be deemed
effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by confirmed facsimile if sent during the normal business hours of the recipient, if not, then on the next business day; (iii) one
(1) business day after deposit with a nationally recognized overnight courier designating next business day delivery; or (iv) five (5) days after having been sent by registered or certified mail, return receipt requested, postage
prepaid. All 
  

 3 








 communications shall be sent to the address or facsimile number as set forth on the signature page hereof or at such
other address as such party may designate by ten (10) days’ advance written notice to the other parties. 
 13. Entire
Agreement; Severability. This Note constitutes the full and entire understanding, promise and agreement between Maker and Payee with respect to the subject matter hereof, and it supersedes, merges and renders void every other prior written
and/or oral understanding, promise or agreement between Maker and Payee. If one or more provisions of this Note are held to be unenforceable under applicable law, such provision shall be excluded from this Note, the balance of the Note shall be
interpreted as if such provision were so excluded and shall be enforceable in accordance with its terms, and the parties shall use good faith to negotiate a substitute, valid and enforceable provision that replaces the excluded provision and that
most nearly effects the parties’ intent in entering into this Note. 
 THIS NOTE REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS OF THE PARTIES. 
 14. Governing Law; Jurisdiction; Waiver of Jury Trial. This Note is being executed and delivered and is intended to be performed, in the State of Texas, and the laws of such state shall govern the construction,
validity, enforcement and interpretation hereof, except to the extent federal laws otherwise govern the validity, construction, enforcement and interpretation hereof. Maker hereby irrevocably (a) submits to the non-exclusive jurisdiction of any
United States Federal or State court sitting in Dallas County, Texas in any action or proceeding arising out of or relating to this Note, and (b) waives to the fullest extent permitted by law, any defense asserting an inconvenient forum in
connection therewith. TO THE EXTENT ALLOWED BY LAW, MAKER AND PAYEE EACH WAIVE JURY TRIAL IN ANY ACTION OR PROCEEDING RELATING TO THIS NOTE. 
 15. Headings. The headings of the paragraphs of this Note are inserted for convenience only and shall not be deemed to constitute a part hereof. 
 16. Successors and Assigns. All of the promises and agreements in this Note contained by or on behalf of Maker shall bind its successors and assigns, whether so expressed or not; provided, however, that Maker
may not, without the prior written consent of Payee, assign any rights, duties, or obligations under this Note. 
 17. Maximum Interest
Rate. Regardless of any provision contained herein, or in any other document executed in connection herewith, Payee shall never be entitled to receive, collect or apply, as interest hereon, any amount in excess of the maximum rate of interest
permitted to be charged from time to time by applicable law, and in the event Payee ever receives, collects or applies, as interest, any such excess, such amount which would be excessive interest shall be deemed a partial prepayment of the principal
hereof and treated hereunder as such; and, if the principal hereof is paid in full, any remaining excess shall forthwith be paid to Maker. In determining whether or not the interest paid or payable, under any specified contingency, exceeds the
highest lawful rate, Maker and Payee shall, to the maximum extent permitted under 
  

 4 








 applicable law, (a) characterize any non-principal payment as an expense, fee, or premium rather than as interest,
(b) exclude voluntary prepayments and the effects thereof, and (c) spread the total amount of interest throughout the entire contemplated term hereof; provided that if the indebtedness evidenced hereby is paid and performed in full prior
to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the maximum lawful rate, Payee shall refund to Maker the amount of such excess or credit the amount of such excess
against the principal hereof, and in such event, Payee shall not be subject to any penalties provided by any laws for contracting for, charging, or receiving interest in excess of the maximum lawful rate.
