The foregoing shall not apply to trade payables incurred in the ordinary course of business or professional fees.

ARTICLE III

SECURITY INTEREST

     3. Security Interest/Waiver of Automatic Stay. This Note is secured by a security interest granted to the Holder pursuant to an Omnibus Security Interest Acknowledgement executed and delivered by Borrower in favor of Holder, on or about July 19, 2007 and other agreements referred to therein, as delivered by Borrower to Holder. Furthermore, this Note shall be deemed to be a New Loan as defined in the aforesaid Omnibus Security Interest acknowledgement. The Borrower acknowledges and agrees that should a proceeding under any bankruptcy or insolvency law be commenced by or against the Borrower, or if any of the Collateral (as defined in the an Omnibus Security Interest Acknowledgement and other agreements referred to therein) should become the subject of any bankruptcy or insolvency proceeding, then the Holder should be entitled to, among other relief to which the Holder may be entitled under this Note, the an Omnibus Security Interest Acknowledgement and other agreements referred to therein and any other agreement to which the Borrower and Holder are parties (collectively, “Loan Documents”) and/or applicable law, an order from the court granting immediate relief from the automatic stay pursuant to 11 U.S.C. Section 362 to permit the Holder to exercise all of its rights and remedies pursuant to the Loan Documents and/or applicable law. THE BORROWER EXPRESSLY WAIVES THE BENEFIT OF THE AUTOMATIC STAY IMPOSED BY 11 U.S.C. SECTION 362. FURTHERMORE, THE BORROWER EXPRESSLY ACKNOWLEDGES AND AGREES THAT NEITHER 11 U.S.C. SECTION 362 NOR ANY OTHER SECTION OF THE BANKRUPTCY CODE OR OTHER STATUTE OR RULE (INCLUDING, WITHOUT LIMITATION, 11 U.S.C. SECTION 105) SHALL STAY, INTERDICT, CONDITION, REDUCE OR INHIBIT IN ANY WAY THE ABILITY OF THE HOLDER TO ENFORCE ANY OF ITS RIGHTS AND REMEDIES UNDER THE LOAN DOCUMENTS AND/OR APPLICABLE LAW. The Borrower hereby consents to any motion for relief from stay that may be filed by the Holder in any bankruptcy or insolvency proceeding initiated by or against the Borrower and, further, agrees not to file any opposition to any motion for relief from stay filed by the Holder. The Borrower represents, acknowledges and agrees that this provision is a specific and material aspect of the Loan Documents, and that the Holder would not agree to the terms of the Loan Documents if this waiver were not a part of this Note. The Borrower further represents, acknowledges and agrees that this waiver is knowingly, intelligently and voluntarily made, that neither the Holder nor any person acting on behalf of the Holder has made any representations to induce this waiver, that the Borrower has been represented (or has had the opportunity to he represented) in the signing of the Loan Documents and in the making of this waiver by independent legal counsel selected by the Borrower and that the Borrower has discussed this waiver with counsel.

     4.6 Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of New York, without regard to its conflict of laws principles. Any action brought by either party against the other concerning the transactions contemplated by this Agreement shall be brought only in the civil or state courts of New York or in the federal courts located in the State and county of New York. Both parties and the individual signing this Agreement on behalf of the Borrower agree to submit to the jurisdiction of such courts. The prevailing party shall be entitled to recover from the other party its reasonable attorney’s fees and costs. In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or unenforceability of any other provision of this Note. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Borrower in any other jurisdiction to collect on the Borrower’s obligations to Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other decision in favor of the Holder. This Note shall be deemed an unconditional obligation of Borrower for the payment of money and, without limitation to any other remedies of Holder, may be enforced against Borrower by summary proceeding pursuant to New York Civil Procedure Law and Rules Section 3213 or any similar rule or statute in the jurisdiction where enforcement is sought. For purposes of such rule or statute, any other document or agreement to which Holder and Borrower are parties or which Borrower delivered to Holder, which may be convenient or necessary to determine Holder’s rights hereunder or Borrower’s obligations to Holder are deemed a part of this Note, whether or not such other document or agreement was delivered together herewith or was executed apart from this Note.

     4.7 Limitation on Interest. All agreements between Borrower and Holder are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration of maturity of the indebtedness evidenced hereby or otherwise, shall the amount paid or agreed to be paid to lender for the use or the forbearance of the indebtedness evidenced hereby exceed the maximum permissible under applicable law. As used herein, the term “applicable law” shall mean the law in effect as of the date hereof, provided, however that in the event there is a

change in the law which results in a higher permissible rate of interest, then this Agreement shall be governed by such new law as of its effective date. In this regard, it is expressly agreed that it is the intent of Borrower and Holder in the execution, delivery and acceptance of the Note to comply in strict compliance with the laws of the State of New York and any other applicable state from time to time in effect. If, under or from any circumstances whatsoever, fulfillment of any provision hereof or of any of the Loan Documents at the time of performance of such provision shall be due, shall involve transcending the limit of such validity prescribed by applicable law, then the obligation to be fulfilled shall automatically be reduced to the limits of such validity, and if under or from circumstances whatsoever Lender should ever receive as interest an amount which would exceed the then highest lawful rate, such amount which would be excessive interest shall be applied to the reduction of the principal balance evidenced hereby and not to the payment of interest. This provision shall control every other provision of all agreements between Borrower and Holder.

     IN WITNESS WHEREOF, Borrower has caused this Note to be signed in its name by an authorized officer as of the 28 day of November, 2007.

     Re: Restructuring Fee

Dear Wayne:

The purpose is to set forth Irvine’s agreement to pay certain fees to Longview in connection with Longview’s assistance in restructure of its debt obligations over the past year.

Specifically, Longview has assisted in the original transfer and restructure of the various Notes with the Pequot Funds in December 2006 and the subsequent restructure of the transferred notes in September 2007. Additionally, Longview has structured and assisted with funding the December 2006 Term Loan Agreement, July 2007 Secured Note, and November 2007 Debt Restructuring. Lastly, Longview has previously worked with Irvine to coordinate certain subordination arrangements with other Irvine Lenders, as well as worked out waivers of certain obligations of Irvine under certain of its agreements with its Lenders during the same time period. Collectively, the services described in this paragraph are the “Services”.

In consideration for provision of the Services, Irvine agrees to pay Longview the sum of One Million Dollars ($1,000,000), which are deemed to be fully earned as of the date of this letter. Irvine is delivering to Longview simultaneously with this letter a fully executed Secured Promissory Note (Restructuring), in the amount of One Million Dollars ($1,000,000) as consideration for payment of the amounts due hereunder for Services. Terms of payment are as set forth in the Secured Promissory Note.

Very truly yours,

IRVINE SENSORS CORPORATION
