FOR VALUE RECEIVED, the undersigned, LUCID, INC., a New York corporation (the “Borrower”), hereby promises to pay, on demand, to NORTHEAST LCD CAPITAL, LLC (“NE”), at such place or places as may be specified by NE, in legal tender of the United States of America, the aggregate unpaid principal amount of TWO MILLION THREE HUNDRED FORTY THOUSAND SEVEN HUNDRED NINETY TWO DOLLARS and EIGHTY-FIVE CENTS($2,340,792.85), or such lesser amount as shall then equal the outstanding principal amount hereunder (the “Principal Amount”), together with interest on the unpaid principal balance to accrue at the Applicable Rate, computed on the basis of the actual number of days elapsed and a year of 365 days, from the date of this Note until the Principal Amount and all interest accrued thereon and all other amounts owed hereunder are paid.  The unpaid Principal Amount, together with any then unpaid accrued interest and all other amounts owed hereunder (the “Outstanding Balance”), shall be due and payable on written demand of NE at any time after the date hereof.

1.                                      Payment of Principal and Interest.  Subject to Section 5 below, this Note will bear simple interest on the amount of the unpaid principal balance from the date hereof until paid in full at an interest rate of 7%, per annum (the “Applicable Rate”).

1.1.                            Application of Payments.  Any payment of this Note shall be deemed to be applied first to the payment of accrued interest and then to the repayment of the Principal Amount.

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

2.                                      Security Interest.

2.1.                            Grant of Security Interest Pursuant to Security Agreement.  Pursuant to that certain Security Agreement dated as of the date hereof (as amended, amended and restated, supplemented or otherwise modified from time to time the “Security Agreement”) and executed by and among the Borrower and NE, the Borrower has granted a security interest in the Collateral (as defined therein) to NE as security for the full and punctual payment of principal and interest when due and payable hereunder (whether upon demand, or otherwise), and any other amounts owing hereunder.

2.2.                            Protective Action.  The Borrower will defend NE’s right, title and interest in and to the Collateral against the claims and demands of all other persons.

2.3.                            Events of Default.  The failure by the Borrower to pay any principal, interest or other amount due under this Note on or before the date the same is due shall be an “Event of Default” for all purposes of this Note.  Upon the occurrence of an Event of Default and so long as such Event of Default shall be continuing, NE may exercise any rights or remedies available to it under the terms of this Note, the Security Agreement, the Maine Uniform Commercial Code and at common law.

2.4.                            Rights and Remedies of NE in an Event of Default.  NE shall have and may exercise any and all rights and remedies afforded to a secured party under the Uniform Commercial Code in effect in the State of

Maine and shall have the right to retain the Collateral in partial or full satisfaction of the Borrower’s obligations under this Note in accordance with the provisions of, and to the extent permitted under, the Maine Uniform Commercial Code.  With respect to the preceding sentence, NE shall, in its sole discretion, to the extent permitted under the Maine Uniform Commercial Code, determine the order in which all or any portion of the assets comprising the Collateral shall be applied in satisfaction of the Borrower’s obligations under this Note.  The remedies of NE as provided herein, or any one or more of them, in law or at equity, shall be cumulative and concurrent, and may be pursued singularly, successively or together at NE’s sole discretion, and may be exercised as often as occasion therefor shall occur.

2.5.                            Annulment of Event of Default.  An Event of Default shall not be deemed to be in existence or to be continuing for any purpose under this Note if NE shall have waived such Event of Default in writing or stated in writing that the same has been cured to its reasonable satisfaction, but no such waiver shall extend to or affect any subsequent Event of Default or impair any rights of NE upon the occurrence thereof.

2.6.                            Borrower Waivers.  The Borrower, and all endorsers, sureties, guarantors and accommodation parties of this Note, and all other persons liable or to become liable for all or any part of the indebtedness evidenced hereby, hereby waive, jointly and severally, to the extent not prohibited by applicable law (i) all presentments, demands for performance, notices of nonperformance (except to the extent required by the provisions hereof), protests, notices of protest and notices of dishonor, (ii) any requirement of diligence or promptness on the part of NE in the enforcement of its rights under the provisions of this Note, (iii) any and all notices of every kind and description which may be required to be given by any statute or rule of law and (iv) any defense of any kind (other than payment) which it may not or hereafter have with respect to its liability under this Note.

2.7.                            Course of Dealing.  No course of dealing between the Borrower and NE shall operate as a waiver of any of the rights under this Note.  No delay or omission on the part of NE in exercising any right under this Note shall operate as a waiver of such right or any other right hereunder.  A waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.  No waiver or consent shall be binding unless it is in writing and signed by NE.

3.                                      Further Assurances.  The Borrower agrees that at any time and from time to time upon the written request of NE, the Borrower will execute and deliver such further documents and do or cause to be done such further acts and things as NE may reasonably request in order to effect the purposes of this Note.
