WARRANT AGREEMENT (“Agreement”), dated as of July 9, 2009, by and between Suspect Detection Systems Inc., a Delaware corporation (the “Company”), and NG-The Northern Group LP (the "Warrantholder"). Certain capitalized terms used herein are defined in Section 15 hereof.

In consideration of the mutual terms, conditions, representations, warranties and agreements herein set forth, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:

Section 1. Issuance of Warrants.

A.           The Company hereby issues and grants to Warrantholder Two Million Two Hundred Fifty Thousand (2,250,000) stock purchase warrants (hereinafter referred to as “Warrants”).

B.           Each Warrant shall grant to the holder thereof the right to purchase one (1) share of common stock of the Company (the “Common Stock”).  Commencing on the date hereof (the “Warrant Commencement Date”), and terminating on July 8, 2011 (the “Warrant Expiration Date”), the holder shall have the right, subject to the satisfaction of the conditions to exercise set forth in Section 7 of this Agreement, to purchase one (1) share of Common Stock per each Warrant (the shares of Common Stock issuable upon exercise of the Warrants being collectively referred to herein as the “Warrant Shares”) at an exercise price of $0.15 per Warrant Share (the “Exercise Price”).  The number of Warrant Shares issuable on exercise of each Warrant and the Exercise Price are all subject to adjustment pursuant to Section 8 of this Agreement.

Section 2. Form of Warrant Certificates.

Promptly after the execution and delivery of this Agreement by the parties hereto, the Company may, in its sole and absolute discretion, cause to be executed and delivered to Warrantholder one or more certificates evidencing the Warrants (the “Warrant Certificates”).  Each Warrant Certificate delivered hereunder shall be substantially in the form set forth in Exhibit Warrant Form attached hereto and may have such letters, numbers or other identification marks and legends, summaries or endorsements printed thereon as the Company may deem appropriate and that are not inconsistent with the terms of this Agreement or as may be required by applicable law, rule or regulation.  Each Warrant Certificate shall be dated the date of execution by the Company.

Section 3. Execution of Warrant Certificates.

Each Warrant Certificate delivered hereunder shall be signed on behalf of the Company by at least one of the following: its Chief Executive Officer, President, Vice President, Secretary or Assistant Secretary.  Each such signature may be in the form of a facsimile thereof and may be imprinted or otherwise reproduced on the Warrant Certificates.

If any officer of the Company who signed any Warrant Certificate ceases to be an officer of the Company before the Warrant Certificate so signed shall have been delivered by the Company, such Warrant Certificate nevertheless may be delivered as though such person had not ceased to be such officer of the Company.

Section 4. Registration of Ownership and Transfer.

Warrant Certificates shall be issued in registered form only.  The Company will keep or cause to be kept books for registration of ownership and transfer of each Warrant Certificate issued pursuant to this Agreement.  Each Warrant Certificate issued pursuant to this Agreement shall be numbered by the Company and shall be registered by the Company in the name of the holder thereof (initially the Warrantholder).  The Company may deem and treat the registered holder of any Warrant Certificate as the absolute owner thereof (notwithstanding any notation of ownership or other writing thereon made by anyone) for the purpose of any exercise thereof and for all other purposes, and the Company shall not be affected by any notice to the contrary.

Section 5. No Transfers.

No Warrant may be sold, pledged, hypothecated, assigned, conveyed, transferred or otherwise disposed of without the agreement of the Company, which will not be unreasonably withheld.

Section 6. Mutilated or Missing Warrant Certificates.

If any Warrant Certificate is mutilated, lost, stolen or destroyed, the Company shall issue, upon surrender and cancellation of any mutilated Warrant Certificate, or in lieu of and substitution for any lost, stolen or destroyed Warrant Certificate, a new Warrant Certificate of like tenor and representing an equal number of Warrants.  In the case of a lost, stolen or destroyed Warrant Certificate, a new Warrant Certificate shall be issued by the Company only upon the Company’s receipt of reasonably satisfactory evidence of such loss, theft or destruction and, if requested, an indemnity or bond reasonably satisfactory to the Company.

Section 7. Exercise of Warrants.

A.           Exercise.  Subject to the terms and conditions set forth in this Section 7, Warrants may be exercised, in whole or in part (but not as to any fractional part of a Warrant), at any time or from time to time on and after the Warrant Commencement Date and on or prior to 5:00 p.m., Eastern time, on the Warrant Expiration Date.

In order to exercise any Warrant, Warrantholder shall deliver to the Company at its office referred to in Section 16 the following: (i) a written notice in the form of the Election to Purchase appearing at the end of the form of Warrant Certificate attached as Exhibit Warrant Form hereto of such Warrantholder’s election to exercise the Warrants, which notice shall specify the number of such Warrantholder’s Warrants being exercised; (ii) the Warrant Certificate or Warrant Certificates, if any, evidencing the Warrants being exercised; and (iii) payment of the aggregate Exercise Price.

All rights of Warrantholder with respect to any Warrant that has not been exercised, on or prior to 5:00 p.m., Eastern time, on the Warrant Expiration Date shall immediately cease and such Warrants shall be automatically cancelled and void.

B.           Payment of Exercise Price.  Payment of the Exercise Price with respect to Warrants being exercised hereunder shall be made by the payment to the Company, in cash, by check or wire transfer, of an amount equal to the Exercise Price multiplied by the number of Warrants then being exercised.

- 2 -

C.           Payment of Taxes.  The Company shall be responsible for paying any and all issue, documentary, stamp or other taxes that may be payable in respect of any issuance or delivery of Warrant Shares on exercise of a Warrant. Notwithstanding anything contained herein to the contrary, the Warrantholder shall be responsible for all taxes that may be due and payable by the Warrantholder as a result of the issuance of this Warrant to the Warrantholder or as a result of the issuance of the Warrant Shares upon due exercise hereof.

D.           Delivery of Warrant Shares.  Upon receipt of the items referred to in Section 7A, the Company shall, as promptly as practicable, execute and deliver or cause to be executed and delivered, to or upon the written order of Warrantholder, and in the name of Warrantholder or Warrantholder’s designee, a stock certificate or stock certificates representing the number of Warrant Shares to be issued on exercise of the Warrant(s).  If the Warrant Shares shall in accordance with the terms thereof have become automatically convertible into shares of the Company’s Common Stock prior to the time a Warrant is exercised, the Company shall in lieu of issuing shares of Common Stock, issue to the Warrantholder or its designee on exercise of such Warrant, a stock certificate or stock certificates representing the number of shares of Common Stock into which the Warrant Shares issuable on exercise of such Warrant are convertible.  The certificates issued to Warrantholder or its designee shall bear any restrictive legend required under applicable law, rule or regulation.  The stock certificate or certificates so delivered shall be registered in the name of Warrantholder or such other name as shall be designated in said notice.  A Warrant shall be deemed to have been exercised and such stock certificate or stock certificates shall be deemed to have been issued, and such holder or any other Person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date that such notice, together with payment of the aggregate Exercise Price and the Warrant Certificate or Warrant Certificates evidencing the Warrants to be exercised, is received by the Company as aforesaid.  If the Warrants evidenced by any Warrant Certificate are exercised in part, the Company shall, at the time of delivery of the stock certificates, deliver to the holder thereof a new Warrant Certificate evidencing the Warrants that were not exercised or surrendered, which shall in all respects (other than as to the number of Warrants evidenced thereby) be identical to the Warrant Certificate being exercised.  Any Warrant Certificates surrendered upon exercise of Warrants shall be canceled by the Company.

Section 8. Adjustment of Number of Warrant Shares Issuable Upon Exercise of a Warrant and Adjustment of Exercise Price.

A.           Adjustment for Stock Splits, Stock Dividends, Recapitalizations.  The number of Warrant Shares issuable upon exercise of each Warrant and the Exercise Price shall each be proportionately adjusted to reflect any stock dividend, stock split, reverse stock split, recapitalization or the like affecting the number of outstanding shares of Common Stock that occurs after the date hereof.

B.           Adjustments for Reorganization, Consolidation, Merger.  If after the date hereof, the Company (or any other entity, the stock or other securities of which are at the time receivable on the exercise of the Warrants), consolidates with or merges into another entity or conveys all or substantially all of its assets to another entity, then, in each such case, Warrantholder, upon any permitted exercise of a Warrant (as provided in Section 7), at any time after the consummation of such reorganization, consolidation, merger or conveyance, shall be entitled to receive, in lieu of the stock or other securities and property receivable upon the exercise of the Warrant prior to such consummation, the stock or other securities or property to which such Warrantholder would have been entitled upon the consummation of such reorganization, consolidation, merger or conveyance if such Warrantholder had exercised the Warrant immediately prior thereto, all subject to further adjustment as provided in this Section 8.  The successor or purchasing entity in any such reorganization, consolidation, merger or conveyance (if other than the Company) shall duly execute and deliver to Warrantholder a written acknowledgment of such entity’s obligations under the Warrants and this Agreement.

C.           Notice of Certain Events.

Upon the occurrence of any event resulting in an adjustment in the number of Warrant Shares (or other stock or securities or property) receivable upon the exercise of the Warrants or the Exercise Price, the Company shall promptly thereafter (i) compute such adjustment in accordance with the terms of the Warrants, (ii) prepare a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based, and (iii) mail copies of such certificate to Warrantholder.

Section 9. Reservation of Shares.

The Company shall at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Common Stock, or its authorized and issued Common Stock held in its treasury, the aggregate number of the Warrant Shares deliverable upon the exercise of all outstanding Warrants, for the purpose of enabling it to satisfy any obligation to issue the Warrant Shares upon the due and punctual exercise of the Warrants, through 5:00 p.m., Eastern time, on the Warrant Expiration Date.

Section 10. No Impairment.

The Company shall not, by amendment of its certificate of incorporation or bylaws, or through reorganization, consolidation, merger, dissolution, issuance or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid the observance or performance of any of the terms of the Warrants or this Agreement, and shall at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate in order to protect the rights of Warrantholder under the Warrants and this Agreement against wrongful impairment.  Without limiting the generality of the foregoing, the Company:  (i) shall not set or increase the par value of any Warrant Shares above the amount payable therefor upon exercise, and (ii) shall take all actions that are necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of the Warrants.
