As soon as practicable, but in no event later than the Shareholder Meeting Date Deadline, hold an annual meeting of its shareholders (the “Meeting”) to obtain the Shareholder Approval. In connection therewith, the Borrower shall use its best efforts to obtain the Shareholder Approval at the Meeting.

(n) Payment of Principal, Interest and Other Amounts Due. Pay when due all Obligations to the Lender and all other amounts payable by it hereunder and under the Notes; provided, however, that notwithstanding the respective Maturity Dates of the Notes, the Borrower covenants to make partial principal payments under the Notes from time to time after June 30, 2010 upon the Borrower’s reasonable determination, upon consultation with the Lender, that the Borrower has more working capital than it reasonably projects that it will require to cover its expenses over a rolling ninety (90) day period, and the Borrower does not have any other foreseeable longer term obligations that it projects it would not otherwise be able to repay through cash flow generated from operations or other available sources of capital without the use of such excess working capital; provided, further, that the making of any such partial payments does not violate the terms of the Subordination Agreement as then in effect, or if any such payments would result in such violation, the Senior Lender shall have waived such violation or consented to the payments.

(o) Filing of Series E Preferred Stock Statement With Respect to Shares and Conversion and Exchange of the 2003 Note, Series B Preferred Stock and Series C Preferred Stock into Series E Preferred Stock. As soon as practicable following the receipt by the Borrower of the Shareholder Approval, but in no event later than two (2) business days thereafter, the Borrower shall file the Series E Preferred Stock Statement With Respect to Shares in substantially the form of Exhibit C hereto with the Department of State of the Commonwealth of Pennsylvania and shall effect the conversion and exchange of the 2003 Note, Series B Preferred Stock and Series C Preferred Stock into Series E Preferred Stock as contemplated by Section 3.5 hereof.

or in connection with any of the Transaction Documents, shall survive the execution and delivery of all of the Transaction Documents, and the issuance, sale and delivery of the Notes and the Warrants. For the avoidance of doubt, no payment shall be deemed to have been indefeasibly paid in full, whether made by the Borrower or the Guarantor or any other person, which is required to be refunded pursuant to any bankruptcy or insolvency law; it being understood that no payment so refunded shall be considered as a payment of any portion of the Credit Facility, nor shall it have the effect of reducing the obligation or the liability of the Borrower or the Guarantor hereunder or any Transaction Document.

9.2 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that (i) the Borrower may not assign or transfer its rights or obligations hereunder or any interest herein or delegate their duties hereunder and (ii) the Lender shall have the right to assign his rights hereunder and under the Securities in accordance with Article 6.

The rights and remedies hereunder are cumulative and not exclusive of any rights or remedies that the Lender would otherwise have. Any waiver, permit, consent or approval of any kind or character of any breach or default under this Agreement or any such waiver of any provision or condition of this Agreement must be in writing and shall be effective only to the extent in such writing specifically set forth.

This Warrant is subject to the following terms, provisions and conditions:

1. Number of Shares. During the Exercise Period, the Holder shall be entitled to purchase shares of Common Stock under this Warrant, which number of shares of Common Stock was determined by multiplying the principal amount of the applicable Note to which this Warrant relates by 10% and dividing that number by the Market Price (as hereinafter defined) as of the Issue Date (as hereinafter defined); provided, however, that if the Shareholder Approval is not obtained by the Shareholder Approval Date, the Holder shall be entitled to purchase shares of Common Stock, which number of shares was determined by multiplying the principal amount of the applicable Note to which this Warrant relates by 50% and dividing by the Market Price as of the Issue Date for the Company’s Common Stock for which this Note and this Warrant relate.

2. Exercise Price. The exercise price of this Warrant (the “Exercise Price”) shall be a price per share equal to $ , which is the Market Price as of the Issue Date; provided,

however, that if the Shareholder Approval is not obtained by the Shareholder Approval Date, the Exercise Price shall be $ , which is 50% of the foregoing Market Price.

3. Period of Exercise. This Warrant is exercisable at any time or from time to time beginning on the date of issuance (the “Issue Date”) and ending at 5:00 p.m., Philadelphia, Pennsylvania time on the seventh (7^th) anniversary of the Issue Date (the “Exercise Period”).

4. Manner of Exercise; Issuance of Certificates; Payment for Shares. Subject to the provisions hereof, this Warrant may be exercised by the Holder hereof, in whole or in part, by the surrender of this Warrant, together with a completed exercise agreement in the form attached hereto (the “Exercise Agreement”), to the Company during normal business hours on any business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the Holder hereof), and upon payment to the Company in cash, by certified or official bank check or by wire transfer for the account of the Company of the Exercise Price for the Warrant Shares specified in the Exercise Agreement. The Warrant Shares so purchased shall be deemed to be issued to the Holder hereof or such Holder’s designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered, the completed Exercise Agreement shall have been delivered and payment shall have been made for such shares as set forth above. Certificates for the Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the Holder hereof within fifteen (15) business days after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the Holder hereof and shall be registered in the name of such Holder or such other name as shall be designated by such Holder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, as soon as practicable after the date of exercise, deliver to the Holder a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised.

5. Certain Agreements of the Company. The Company hereby covenants and agrees as follows:

(d) Certain Actions Prohibited. The Company will not, by amendment of its charter or through any reorganization, transfer of assets, consolidation, merger, dissolution,

issue or sale of securities, or any other voluntary action, directly or indirectly, by operation of law or otherwise, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder of this Warrant in order to protect the exercise privilege of the Holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

(e) Successors and Assigns. This Warrant will be binding upon any entity succeeding to the Company or its assets.

6. Antidilution Provisions. During the Exercise Period, the Exercise Price and the number of Warrant Shares shall be subject to adjustment from time to time as provided in this Section 6.

(a) Sale of Securities Below Current Exercise Price. Except as otherwise provided in Sections 6(b) and 6(d), if at any time the Company shall issue or, pursuant to the provisions hereof, be deemed to have issued (other than as set forth in Section 6(a)(vi) hereof) any shares of Common Stock, Convertible Securities (as hereinafter defined), Rights (as hereinafter defined) or Related Rights (as hereinafter defined) (collectively, “Securities”) without consideration or for a consideration per share less than the Exercise Price in effect immediately prior to the issuance of such Securities, then the Exercise Price in effect immediately prior to each such issuance shall forthwith be reduced to a price determined in accordance with the following formula:

EP₂ = EP₁* (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(a) “EP₂” shall mean the Exercise Price for the Common Stock in effect immediately after such issuance of Securities;

(b) “EP₁” shall mean the Exercise Price of the Common Stock in effect immediately prior to such issuance of Securities;

(c) “A” shall mean the number of shares of Common Stock actually outstanding immediately prior to such issuance of Securities (excluding shares of Common Stock issuable on conversion or exercise of preferred stock, convertible promissory notes, options, warrants and other options to purchase or rights to subscribe for such convertible or exchangeable securities);

(d) “B” shall mean the number of additional shares of Common Stock that would have been issued if such Securities had been issued at a price per share equal to EP₁ (determined by dividing the aggregate consideration received by the Company in respect of such issue by EP₁); and

(e) “C” shall mean the number of such Securities issued in such transaction.

For the purpose of this Section 6(a), the following definitions, procedures and exceptions shall be applicable:

(i) Rights. In the case of the issuance of options, warrants or other rights to purchase or otherwise acquire shares of Common Stock, whether or not at the time exercisable (collectively, “Rights”), the total number of shares of Common Stock issuable upon exercise of such Rights shall be deemed to have been issued at the time such Rights are issued, for a consideration equal to the sum of the consideration, if any, received by the Company upon the issuance of such Rights and the minimum purchase or exercise price payable upon the exercise of such Rights for the Common Stock to be issued upon the exercise thereof; and the consideration per share shall be determined by dividing (i) the aggregate consideration so received by and payable to the Company, by (ii) the number of shares of Common Stock issuable upon exercise of such Rights.

(ii) Convertible Securities and Related Rights. In the case of the issuance of any class or series of stock or any bonds, debentures, notes or other securities or obligations convertible into or exchangeable for Common Stock, whether or not then convertible or exchangeable (collectively, “Convertible Securities”), or options, warrants or other rights to purchase or otherwise acquire Convertible Securities (collectively, “Related Rights”), the total number of shares of Common Stock issuable upon the conversion or exchange of such Convertible Securities or exercise of such Related Rights shall be deemed to have been issued at the time such Convertible Securities or Related Rights are issued, for a consideration equal to the sum of (A) the consideration, if any, received by the Company upon issuance of such Convertible Securities or Related Rights (excluding any cash received on account of accrued interest or dividends) and (B)(1) in the case of Convertible Securities, the minimum additional consideration, if any, to be received by the Company upon the conversion or exchange of such Convertible Securities or (2) in the case of Related Rights, the sum of (x) the minimum purchase or exercise price payable upon the exercise of such Related Rights for Convertible Securities and (y) the minimum additional consideration, if any, to be received by the Company upon the conversion or exchange of the Convertible Securities issued upon the exercise of such Related Rights; and the consideration per share shall be determined by dividing (i) the aggregate consideration so received by and payable to the Company, by (ii) the number of shares of Common Stock issuable upon conversion or exchange of such Convertible Securities or exercise of such Related Rights.

(iii) Changes. On any change in the number of shares of Common Stock issuable upon the exercise of Rights or Related Rights or upon the conversion or exchange of Convertible Securities or on any change in the minimum purchase or exercise price of Rights, Related Rights or Convertible Securities, including, but not limited to, a change resulting from the anti-dilution provisions of such Rights, Related Rights or Convertible Securities, the Exercise Price to the extent in any way affected by such Rights, Related Rights or Convertible Securities shall forthwith be readjusted to be thereafter the Exercise Price that would have been obtained had the adjustment which was made upon the issuance of such Rights, Related Rights or Convertible Securities been made after giving effect to such change. No further adjustment shall be made in respect of such change upon the actual issuance of Common Stock or any payment of

consideration upon the exercise of such Rights or Related Rights or the conversion or exchange of such Convertible Securities.

(iv) Expiration or Cancellation. On the expiration or cancellation of any such Rights, Related Rights or Convertible Securities, if the Exercise Price shall have been adjusted upon the issuance thereof, the Exercise Price shall forthwith be readjusted to such Exercise Price as would have been obtained had the adjustment made upon the issuance of such Rights, Related Rights or Convertible Securities been made upon the basis of the issuance of only the number of shares of Common Stock actually issued upon the exercise of such Rights or Related Rights or the conversion or exchange of such Convertible Securities.

(v) Cash. In the case of the issuance of such Securities for cash, the amount of consideration received by the Company shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof. In the case of the issuance of such Securities for consideration other than cash, the amount of consideration received by the Company shall be determined in good faith by the Company’s Board of Directors.

(vi) Exceptions to Adjustment of Exercise Price. No adjustment to the Exercise Price will be made (i) upon the exercise of any warrants, options or convertible securities issued and outstanding on the Issue Date that are set forth on Schedule 5.1(f) of the Purchase Agreement in accordance with the terms of such securities as of such date; (ii) upon exercise of any stock or options which may hereafter be exercised under any employee benefit plan of the Company now existing or to be implemented in the future, so long as the issuance of such stock or options is approved by a majority of the non-employee members of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose; (iii) upon the issuance of the Warrants issued or issuable in accordance with the terms of the Purchase Agreement; (iv) upon exercise of the Warrants; (v) upon the issuance of any shares of Series E Preferred Stock in exchange for existing series of Preferred Stock of the Company as provided in the Purchase Agreement or the issuance of Common Stock in conversion thereof; (vi) upon the issuance of any shares of Series D Preferred Stock in payment of fees and/or interest on the Notes as provided in the Purchase Agreement or the issuance of Common Stock in conversion thereof; or (vi) upon the issuance of securities in connection with a strategic transaction that is approved by the Board of Directors of the Company, including the Holder if then a director.

(b) Subdivision or Combination of Common Stock. If the Company at any time subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable hereunder into a greater number of shares, then, after the date of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) the shares of Common Stock acquirable hereunder into a smaller number of shares, then, after the date of record for effecting such combination, the Exercise Price in effect immediately prior to such combination will be proportionately increased.

(c) Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to the provisions of this Section 6, the number of shares of Common Stock issuable upon exercise of this Warrant shall be adjusted by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of this Warrant immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price.

(d) Consolidation, Merger or Sale. In case of any consolidation of the Company with, or merger of the Company into any other company, or in case of any sale or conveyance of all or substantially all of the assets of the Company other than in connection with a plan of complete liquidation of the Company, then as a condition of such consolidation, merger or sale or conveyance, adequate provision will be made whereby the Holder of this Warrant will have the right to acquire and receive upon exercise of this Warrant in lieu of the shares of Common Stock immediately theretofore acquirable upon the exercise of this Warrant, such shares of stock, securities or assets as the Holders of the Warrants would have received had the Warrants been exercised immediately prior to such consolidation, merger or sale or conveyance. In any such case, the Company will make appropriate provision to insure that the provisions of this Section 6 hereof will thereafter be applicable as nearly as may be in relation to any shares of stock or securities thereafter deliverable upon the exercise of this Warrant. The Company will not effect any consolidation, merger or sale or conveyance unless prior to the consummation thereof, the successor or acquiring entity (if other than the Company) and, if an entity different from the successor or acquiring entity, the entity whose capital stock or assets the holders of the Common Stock of the Company are entitled to receive as a result of such consolidation, merger or sale or conveyance assumes by written instrument the obligations of the Company under this Warrant (including under this Section 6) and the obligations to deliver to the Holder of this Warrant such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to acquire. This Section 6(d) shall apply to any successive consolidations, mergers, sales or conveyances.

(e) Distribution of Assets. In case the Company shall declare or make any distribution of its assets (including cash) to holders of Common Stock as a partial liquidating dividend, by way of return of capital or otherwise, then, after the date of record for determining stockholders entitled to such distribution, but prior to the date of distribution, the Holder of this Warrant shall be entitled upon exercise of this Warrant for the purchase of any or all of the shares of Common Stock subject hereto, to receive the amount of such assets which would have been payable to the Holder had such Holder been the holder of such shares of Common Stock on the record date for the determination of stockholders entitled to such distribution.

(f) Notice of Adjustment. Upon the occurrence of any event which requires any adjustment of the Exercise Price, then, and in each such case, the Company shall give notice thereof to the Holder of this Warrant, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease in the number of Warrant Shares purchasable at such price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Such calculation shall be certified by the chief financial officer of the Company.

forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to not less than 1% of such Exercise Price.

(h) No Fractional Shares. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but the Company shall pay a cash adjustment in respect of any fractional share which would otherwise be issuable in an amount equal to the same fraction of the Market Price of a share of Common Stock on the date of such exercise.

(i) Other Notices. In case at any time:

(i) the Company shall declare any dividend upon the Common Stock payable in shares of stock of any class or make any other distribution (including dividends or distributions payable in cash out of retained earnings) to the holders of the Common Stock;

(ii) there shall be any capital reorganization of the Company, or reclassification of the Common Stock, or consolidation or merger of the Company with or into, or sale of all, substantially all or a material portion of its assets to, another Company or entity; or

(iii) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Company;

then, in each such case, the Company shall give to the Holder of this Warrant (a) notice of the date on which the books of the Company shall close or a record shall be taken for determining the holders of Common Stock entitled to receive any such dividend or distribution or for determining the holders of Common Stock entitled to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, notice of the date (or, if not then known, a reasonable approximation thereof by the Company) when the same shall take place. Such notice shall also specify the date on which the holders of Common Stock shall be entitled to receive such dividend, distribution, or subscription rights or to exchange their Common Stock for stock or other securities or property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding-up, as the case may be. Such notice shall be given at least ten (10) business days prior to the record date or the date on which the Company’s books are closed in respect thereto. Failure to give any such notice or any defect therein shall not affect the validity of the proceedings referred to in clauses (i), (ii) and (iii) above; provided that if notice is not given in accordance with this Section 4(i), the Company will use its best efforts to insure that the Holder of this Warrant shall nevertheless receive the same rights and benefits received by other holders of securities of the Company from the proceedings referred to in clauses (i), (ii) and (iii) above, unless the Holder of this Warrant chooses not to receive such rights and benefits.

(j) Certain Events. If any event occurs of the type contemplated by the adjustment provisions of this Section 6 but not expressly provided for by such provisions, the Company will give notice of such event as provided in Section 6(i) hereof, and the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and the number of

shares of Common Stock acquirable upon exercise of this Warrant so that the rights of the Holder shall be neither enhanced nor diminished by such event.

(k) Definition of Market Price. “Market Price,” as of any date, (i) means the closing sale price for the shares of Common Stock as reported on the American Stock Exchange (“AMEX”) by Bloomberg Financial Markets (“Bloomberg”) for the trading day immediately preceding such date, or (ii) if the AMEX is not the principal trading market for the shares of Common Stock, the average of the reported closing sale prices reported by Bloomberg on the principal trading market for the Common Stock during the one hundred twenty (120) day period immediately preceding such date, (iii) if market value cannot be calculated as of such date on any of the foregoing bases, the Market Price shall be determined in good faith by the Board of Directors.

7. Issue Tax. The issuance of certificates for Warrant Shares upon the exercise of this Warrant shall be made without charge to the Holder of this Warrant or such shares for any issuance tax or other costs in respect thereof.

8. No Rights or Liabilities as a Shareholder. This Warrant shall not entitle the Holder hereof to any voting rights, rights to dividends, or other rights as a shareholder of the Company. No provision of this Warrant, in the absence of affirmative action by the Holder hereof to purchase Warrant Shares, and no mere enumeration herein of the rights or privileges of the Holder hereof, shall give rise to any liability of such Holder for the Exercise Price or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

9. Transfer, Exchange and Replacement of Warrant.

(a) Restriction on Transfer. This Warrant and the rights granted to the Holder hereof are transferable, in whole or in part, upon surrender of this Warrant, together with a properly executed assignment in the form attached hereto, at the office or agency of the Company referred to in Section 9(e) below; provided, however, that any transfer or assignment shall be subject to the conditions set forth in Section 9(f). Notwithstanding the foregoing, this Warrant, the shares of Common Stock issuable upon exercise hereof, and the rights granted hereunder may not be transferred to a competitor of the Company or any Subsidiary or affiliate of the Company.

(b) Warrant Exchangeable for Different Denominations. This Warrant is exchangeable, upon the surrender hereof by the Holder hereof at the office or agency of the Company referred to in Section 9(e) below, for new Warrants of like tenor representing in the aggregate the right to purchase the number of shares of Common Stock which may be purchased hereunder, each of such new Warrants to represent the right to purchase such number of shares as shall be designated by the Holder hereof at the time of such surrender.

(c) Replacement of Warrant. Upon receipt of evidence of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company, at its expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

(d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant in connection with any transfer, exchange or replacement as provided in this Section 9, this Warrant shall be promptly canceled by the Company. The Company shall pay all taxes (other than securities transfer taxes) and all other expenses (other than legal expenses, if any, incurred by the Holder or transferees) and charges payable in connection with the preparation, execution, and delivery of Warrants pursuant to this Section 9.

(e) Register. The Company shall maintain, at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the Holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee and each prior owner of this Warrant.

(f) Exercise or Transfer Without Registration. If, at the time of the surrender of this Warrant in connection with any exercise, transfer, or exchange of this Warrant, this Warrant (or, in the case of any exercise, the Warrant Shares issuable hereunder), shall not be registered under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such exercise, transfer, or exchange, that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel to the effect that such exercise, transfer, or exchange may be made without registration under the Securities Act and under applicable state securities or blue sky laws; provided however, that no legal opinion shall be required in connection with a transfer pursuant to Rule 144 under the Securities Act unless in the opinion of counsel to the Company, such transfer does not comply with the provisions of Rule 144. Notwithstanding the foregoing, the initial Holder of this Warrant, by taking and holding the same, represents to the Company that such Holder is acquiring this Warrant for investment and not with a present view to the distribution thereof.

10. Notices. Any notice which is required or provided to be given under this Warrant shall be deemed to have been sufficiently given and received for all purposes when delivered by hand, telecopy (if a copy of such confirmed telecopy transmission shall be contemporaneously sent by first class mail), or nationally recognized overnight courier, or five days after being sent by certified or registered mail, postage and charges prepaid, return receipt requested, to the following addresses:

Exhibit C

Statement With Respect to Shares
of
Series E Convertible Preferred Stock
of
Environmental Tectonics Corporation

Pursuant to Section 1522(b) of the
Business Corporation Law of the Commonwealth of Pennsylvania

In compliance with the requirements of 15 Pa.C.S. § 1522(b) (relating to statements with respect to shares), Environmental Tectonics Corporation, a Pennsylvania corporation (the “Corporation”), desiring to state the designation and voting rights, preferences, limitations, and special rights, if any, of a class or series of its shares, hereby states that:

FIRST: The name of the Corporation is Environmental Tectonics Corporation.

SECOND: The resolution amending the Articles of Incorporation of the Corporation under 15 Pa. C.S. § 1522(b) (relating to divisions and determinations by the board), set forth in full, is as follows:

WHEREAS, the Articles of Incorporation of the Corporation authorizes Preferred Stock consisting of 1,000,000 shares issuable from time to time in one or more series; and

WHEREAS, the Board of Directors of the Corporation (or an authorized committee thereof) is authorized, subject to limitations prescribed by law and by the Articles of Incorporation to establish and fix the number of shares to be included in any series of Preferred Stock and the par value, designation, rights, preferences and limitations of the shares of such series; and

WHEREAS, the Board of Directors, acting through its Audit Committee, intends to establish a new series of Preferred Stock, called Series E Convertible Preferred Stock.

NOW, THEREFORE, BE IT RESOLVED, that pursuant to Article 6 of the Corporation’s Articles of Incorporation, the designation, rights, preferences, powers, restrictions and limitations applicable to the Series E Preferred Stock be and hereby are set forth below:

1. Designation. The designation of this series, which consists of 25,000 shares of Preferred Stock, $0.05 par value per share, is the Series E Convertible Preferred Stock (the “Series E Preferred Stock”) and the stated value shall be One Thousand U.S. Dollars ($1,000.00) per share (the “Stated Value”).

2. Certain Definitions. For purposes of this Statement With Respect to Shares, the following terms shall have the following meanings:

“Common Stock” means the common stock of the Corporation, $0.05 par value per share.

“Conversion Date” means, for any Optional Conversion (as defined below), the date specified in the notice of conversion in the form attached hereto (the “Notice of Conversion”), so long as a copy of the Notice of Conversion is faxed (or delivered by other means resulting in notice) to the Corporation before 4:59 p.m., Philadelphia, Pennsylvania time, on the Conversion Date indicated in the Notice of Conversion; provided, however, that if the Notice of Conversion is not so faxed or otherwise delivered before such time, then the Conversion Date shall be the date the Holder faxes or otherwise delivers the Notice of Conversion to the Corporation.

“Conversion Price” means, with respect to each share of Series E Preferred Stock, $2.00, provided that such Conversion Price shall be subject to adjustment as provided herein.

3. Dividends.

(a) Accruing Dividends. From and after the date any shares of Series E Preferred Stock are issued, the holder of any issued and outstanding shares of Series E Preferred Stock (each a “Holder” and collectively, the “Holders”) shall be entitled to receive, out of funds legally available therefor, cumulative dividends at a rate of ten percent (10%) per annum of the Stated Value on each share of Series E Preferred Stock (the “Accruing Dividends”) in preference to the holders of Common Stock or any other series of Preferred Stock issued by the Corporation after the date hereof and pari passu to the holders of the Series D Preferred Stock of the Corporation (the “Series D Preferred Stock”). The Accruing Dividends shall accrue on each issued and outstanding share of Series E Preferred Stock from the date such share was issued, from day to day, whether or not earned or declared, and shall compound annually and be cumulative. The Corporation shall only pay the Holder the Accruing Dividends upon a Liquidation Event (as hereinafter defined) or when otherwise declared by the Board of Directors of the Corporation.

(b) The Corporation shall not declare, pay or set aside any dividends on shares of any other class or series of capital stock of the Corporation (other than dividends on shares of Common Stock payable in shares of Common Stock) unless (in addition to the obtaining of any consents required elsewhere in the Articles of Incorporation) the holders of the Series E Preferred Stock then outstanding shall first receive a dividend on each outstanding share of Series E Preferred Stock in an amount at least equal to the amount of the aggregate Accruing Dividends then accrued on such share of Series E Preferred Stock and not previously paid.

(c) The Holders shall be entitled to receive, if and when declared by the Board of Directors and paid by the Corporation, any dividends paid with respect to the Common Stock (other than any dividends paid in additional shares of Common Stock). In the case of any such dividend, each Holder shall be entitled to receive an amount per share of Series E Preferred Stock held by such Holder as of the record date for such dividend equal to the product of: (i) the amount of the dividend payable with respect to one share of Common Stock and (ii) the number of shares of Common Stock that would be issued to a Holder if one share of Series E Preferred Stock were converted by the Holder on the record date.

4. Conversion.

(a) Conversion at the Option of the Holder. Each Holder may, at any time and from time to time, convert (an “Optional Conversion”) each of its shares of Series E Preferred Stock plus all accrued but unpaid Accruing Dividends into a number of fully paid and nonassessable shares of the Common Stock determined by dividing the Stated Value plus the aggregate amount of the Accruing Dividends by the Conversion Price for such shares of Series E Preferred Stock.

(b) Mechanics of Conversion. In order to effect an Optional Conversion, a Holder shall: (x) fax (or otherwise deliver) a copy of the fully executed Notice of Conversion to the Corporation or the transfer agent for the Common Stock and (y) surrender or cause to be surrendered the original certificates representing the Series E Preferred Stock being converted (the “Series E Preferred Stock Certificates”), duly endorsed, along with a copy of the Notice of Conversion as soon as practicable thereafter to the Corporation or the transfer agent. Upon receipt by the Corporation of a facsimile copy of a Notice of Conversion from a Holder, the Corporation shall promptly send, via facsimile, a confirmation to such Holder stating that the Notice of Conversion has been received, the date upon which the Corporation expects to deliver the Common Stock issuable upon such conversion and the name and telephone number of a contact person at the Corporation regarding the conversion. The Corporation shall not be obligated to issue shares of Common Stock upon a conversion unless either the Series E Preferred Stock Certificates are delivered to the Corporation or the transfer agent as provided above, or the Holder notifies the Corporation or the transfer agent that such Series E Preferred Stock Certificates have been lost, stolen or destroyed and delivers the documentation to the Corporation required by Section 10(b) hereof.

(i) Delivery of Common Stock Upon Conversion. Upon the surrender of Series E Preferred Stock Certificates accompanied by a Notice of Conversion, the Corporation shall, no later than the later of (a) the third (3^rd) business day following the Conversion Date and (b) the (2^nd) second business day following the date of such surrender (or, in the case of lost, stolen or destroyed certificates, after provision of indemnity pursuant to Section 10(b)) (the “Delivery Period”), issue and deliver to the Holder or its nominee (x) that number of shares of Common Stock issuable upon conversion of such shares of Series E Preferred Stock and Accruing Dividends being converted and (y) a certificate representing the number of shares of Series E Preferred Stock not being converted, if any. If the Corporation’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend and the Holder thereof is not then required to return such certificate for the placement of a legend thereon, the Corporation shall cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Holder by crediting the account of the Holder or its nominee with DTC through its Deposit Withdrawal Agent Commission system (“DTC Transfer”). If the aforementioned conditions to a DTC Transfer are not satisfied, the Corporation shall deliver to the Holder physical certificates representing the Common Stock issuable upon conversion. Further, a Holder may instruct the Corporation to deliver to the Holder physical certificates representing the Common Stock issuable upon conversion in lieu of delivering such shares by way of DTC Transfer.

(ii) No Fractional Shares. If any conversion of Series E Preferred Stock would result in the issuance of a fractional share of Common Stock, such fractional share shall be disregarded, and the number of shares of Common Stock issuable upon conversion of the Series E Preferred Stock shall be rounded off to the nearest whole number of shares.

(iii) Conversion Disputes. In the case of any dispute with respect to a conversion, the Corporation shall promptly issue such number of shares of Common Stock as are not disputed in accordance with subparagraph (i) above. If such dispute involves the calculation of the Conversion Price, the Corporation shall submit the disputed calculations to an independent outside accountant within two (2) business days of receipt of the Notice of Conversion. The accountant, at the Corporation’s expense, shall review the calculations and notify the Corporation and the Holder of the results. The accountant’s calculation shall be deemed conclusive, absent manifest error. The Corporation shall then issue the appropriate number of shares of Common Stock in accordance with subparagraph (i) above no later than two (2) business days from the date it receives the determination from the independent outside accountant.

5. Rank. The Series E Preferred Stock shall rank (i) prior to the Common Stock; (ii) prior to the Series B Preferred Stock; (iii) prior to the Series C Preferred Stock; (iv) prior to any class or series of capital stock of the Corporation hereafter created that does not, by its terms, rank senior to or pari passu with the Series E Preferred Stock (collectively with the Common Stock, the Series B Preferred Stock and the Series C Preferred Stock, “Junior Securities”); (v) pari passu with the Series D Preferred Stock and any class or series of capital stock of the Corporation hereafter created that, by its terms, ranks on parity with the Series D Preferred Stock and Series E Preferred Stock (the “Pari Passu Securities”); and (vi) junior to any class or series of capital stock of the Corporation hereafter created that, by its terms, ranks senior to the Series E Preferred Stock (collectively, the “Senior Securities”), in each case as to distribution of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary.

6. Liquidation Preference.

E Preferred Stock then outstanding. Any acquisition of the Corporation by means of a merger or other form of corporate reorganization approved by the Board of Directors of the Corporation in which all outstanding shares of Common Stock are exchanged for securities or other consideration issued by the acquiring corporation or its subsidiary or the effectuation by the Corporation of a transaction or series of related transactions approved by the Board of Directors of the Corporation in which more than 50% of the voting power is disposed of or the sale, lease or other disposition of all or substantially all of the assets of the Corporation, shall be deemed a Liquidation Event unless the holders of a majority of the outstanding shares of Series E Preferred Stock elect to the contrary; such election to be made by giving written notice thereof to the Corporation at least three (3) days before the closing of such event. For clarification, none of the transactions described in the preceding sentence shall be deemed a Liquidation Event unless any such transaction is approved by the Board of Directors of the Corporation. In such event, the Holders will be entitled to receive in preference to the holders of Junior Securities, the Liquidation Preference with respect to shares of Series E Preferred Stock in the form of cash, securities or other property as is payable in connection with the transaction deemed to be a Liquidation Event. In the event that the Corporation sells, conveys or disposes of all or substantially all of its assets, the Holders will be entitled to receive, prior to the holders of the Junior Securities, if and when the Board of Directors declares a distribution of the consideration received by the Corporation in such asset sale, the Liquidation Preference with respect to the shares of Series E Preferred Stock. If, upon the occurrence of a Liquidation Event, the assets and funds available for distribution among the Holders and holders of Pari Passu Securities shall be insufficient to permit the payment to such holders of the preferential amounts payable thereon, then the entire assets and funds of the Corporation legally available for distribution to the Series E Preferred Stock and the Pari Passu Securities, if any, shall be distributed ratably among such shares in proportion to the ratio that the Liquidation Preference payable on each such share bears to the aggregate Liquidation Preference payable on all such shares. Following payments of preferences to all holders of preferred stock of the Corporation, all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably to the holders of Common Stock, Series E Preferred Stock (on an as-if converted to Common Stock basis) and any other capital stock of the Corporation entitled to share in such distribution.

(b) The “Liquidation Preference” with respect to a share of Series E Preferred Stock means an amount equal to the Stated Value thereof plus any accrued and unpaid dividends thereon, including the Accruing Dividends. The Liquidation Preference with respect to any Pari Passu Securities shall be as set forth in the Statement With Respect to Shares filed in respect thereof.

7. Adjustments to the Conversion Price. The Conversion Price shall be subject to adjustment from time to time as follows:

(a) Stock Splits, Stock Dividends, Etc. If, at any time on or after the date hereof, the number of outstanding shares of Common Stock is increased by a stock split, stock dividend, combination, reclassification or other similar event, the Conversion Price for each share of Series E Preferred Stock shall be proportionately reduced, or if the number of outstanding shares of Common Stock is decreased by a reverse stock split, combination or reclassification of shares, or other similar event, the Conversion Price for each share of Series E Preferred Stock shall be proportionately increased.

(b) Adjustment Due to Merger, Consolidation, Etc. If, at any time after the date hereof, there shall be (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation or merger of the Corporation with any other entity (other than a merger in which the Corporation is the surviving or continuing entity and its capital stock is unchanged), (iii) any sale or transfer of all or substantially all of the assets of the Corporation or (iv) any share exchange pursuant to which all of the outstanding shares of Common Stock are converted into other securities or property (each of (i) - (iv) above being a “Corporate Change”), and, if such Corporate Change is not a Liquidation Event pursuant to the terms of Section 6(a), then the Holders shall thereafter have the right to receive upon conversion, in lieu of the shares of Common Stock otherwise issuable, such shares of stock, securities and/or other property as would have been issued or payable in such Corporate Change with respect to or in exchange for the number of shares of Common Stock which would have been issuable upon conversion had such Corporate Change not taken place, and in any such case, appropriate provisions (in form and substance reasonably satisfactory to the Holders of a majority of the Series E Preferred Stock then outstanding) shall be made with respect to the rights and interests of the Holders to the end that the economic value of the shares of Series E Preferred Stock are in no way diminished by such Corporate Change and that the provisions hereof (including, without limitation, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is not the Corporation, an immediate adjustment of the Conversion Price for each share of Series E Preferred Stock so that the Conversion Price immediately after the Corporate Change reflects the same relative value as compared to the value of the surviving entity’s common stock that existed between the Conversion Price and the value of the Common Stock immediately prior to such Corporate Change).

(i) Weighted Average Anti-Dilution Formula.

(A) If the Corporation issues, after the date hereof (the “Effective Date”), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price for the Series E Preferred Stock in effect immediately prior to the issuance of such Additional Stock, the Conversion Price for the Series E Preferred Stock in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this Section 7(c)(i)) be reduced to a price determined in accordance with the following formula:

CP2 = CP1 * (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(1) “CP2” shall mean the Conversion Price for the Series E Preferred Stock in effect immediately after such issue of Additional Stock

(2) “CP1” shall mean the Conversion Price of the Series E Preferred Stock in effect immediately prior to such issue of Additional Stock;

(3) “A” shall mean the number of shares of Common Stock actually outstanding immediately prior to such issuance of Additional Stock (excluding shares of Common Stock issuable on conversion or exercise of preferred stock, convertible promissory notes, options, warrants and other options to purchase or rights to subscribe for such convertible or exchangeable securities);

(4) “B” shall mean the number of additional shares of Common Stock that would have been issued if such Additional Stock had been issued at a price per share equal to CP1 (determined by dividing the aggregate consideration received by the Corporation in respect of such issue by CP1); and

(5) “C” shall mean the number of such Additional Stock issued in such transaction.

(B) No adjustment of the Conversion Price for any series of Series E Preferred Stock will be made in an amount less than one cent per share, provided that any adjustments that are not required to be made by reason of this sentence will be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the event giving rise to the adjustment being carried forward, or will be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in Sections 7(c)(i)(E)(3) and 7(c)(i)(E)(4), no adjustment of such Conversion Price pursuant to this Section 7(c)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

(C) In the case of the issuance of Common Stock for cash, the consideration will be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed, paid or incurred by the Corporation for any underwriting or otherwise in connection with the issuance and sale thereof.

(D) In the case of the issuance of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash will be deemed to be the fair value thereof as determined in good faith by the Board of Directors irrespective of any accounting treatment.

(E) In the case of the issuance (whether before, on or after the Effective Date) of warrants, options to purchase or rights to subscribe for Common Stock, securities by their terms convertible into or exchangeable for Common Stock or warrants, options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions will apply for all purposes of this Section 7(c)(i) and Section 7(c)(ii):

consideration (determined in the manner provided in Sections 7(c)(i)(C) and 7(c)(i)(D)), if any, received by the Corporation upon the issuance of such warrants, options or rights plus the minimum exercise price provided in such warrants, options or rights the Common Stock covered thereby.

(2) The aggregate maximum number of shares of Common Stock deliverable upon conversion of, or in exchange (to the extent then convertible or exchangeable) assuming the satisfaction of any conditions to convertibility or exchangeability, including, without limitation, the passage of time, for any such convertible or exchangeable securities or upon the exercise of options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof will be deemed to have been issued at the time such securities were issued or such options or rights were issued and for a consideration equal to the consideration, if any, received by the Corporation for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum additional consideration, if any, to be received by the Corporation upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration in each case to be determined in the manner provided in Sections 7(c)(i)(C) and 7(c)(i)(D)).

(3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price of the Series E Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, will be recomputed to reflect such change, but no further adjustment will be made for the actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities.

(4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series E Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, will be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities.

(5) The number of shares of Common Stock deemed issued and the consideration deemed paid therefor pursuant to Sections 7(c)(i)(E)(1) and 7(c)(i)(E)(2) will be appropriately adjusted to reflect any change, termination or expiration of the type described in either Section 7(c)(i)(E)(3) or 7(c)(i)(E)(4).

(ii) Definition of Additional Stock. “Additional Stock” means any shares of Common Stock issued (or deemed to have been issued pursuant to Section 7(c)(i)(E)) by the Corporation after the date hereof other than:

(a) shares of Common Stock issued pursuant to a transaction described in Section 7(a) hereof;

(b) shares of Common Stock issued or issuable to any employee, officer, director, consultant or advisor of the Corporation for services provided to the Corporation directly or pursuant to any employee benefit plan which has been approved by the Board of Directors of the Corporation, so long as the total number of shares of Common Stock so issued or issuable (and not repurchased at cost by the Corporation in connection with the termination of employment or other provision of services to the Corporation and not subject to options that expire unexercised) does not exceed 1,366,890 shares;

(c) shares of Common Stock issued or issuable pursuant to a bona fide firm commitment underwritten public offering with a nationally recognized underwriter that generates gross proceeds in excess of $30,000,000 and that is approved by the Board of Directors of the Corporation, including the Series E Director Nominee;

(d) shares of Common Stock issued pursuant to the conversion, exchange or exercise of convertible or exercisable securities outstanding as of the date hereof or subsequently issued pursuant to this Section 7(c)(ii);

(e) shares of Common Stock issued or issuable in connection with a bona fide business acquisition of or by the Corporation, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise that is approved by the Board of Directors of the Corporation, including the Series E Director Nominee;

(f) shares of Common Stock issuable upon conversion of any shares of Series E Preferred Stock;

(g) shares of Common Stock issuable upon conversion of any shares of any sub-series of Series D Preferred Stock issued in payment of fees or interest under that certain Secured Credit Facility and Warrant Purchase Agreement dated as of April ___, 2009, by and between the Corporation and H.F. Lenfest (the “Purchase Agreement”);

(h) shares of Common Stock issuable upon exercise of those certain warrants to purchase common stock issued or issuable in connection with the transactions contemplated by the Purchase Agreement; or

(i) shares of Common Stock issued pursuant to a transaction in which the Conversion Price adjustments set forth in this Section 7(c) are waived by the holders of at least a majority of the then outstanding shares of Series E Preferred Stock.

(d) Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this Section 7, the Corporation shall promptly compute such adjustment or readjustment and prepare and furnish to each Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based.

8. Voting Rights.

(a) General. The Holders shall be entitled to vote with the holders of Common Stock, voting together as one class, on all matters submitted to a vote of the holders of Common Stock, and each share of Series E Preferred Stock shall be entitled to a number of votes equal to the number of shares of Common Stock into which each such share is convertible as of the record date for the applicable vote. To the extent that under the Pennsylvania Business Corporation Law the vote of the Holders, voting separately as a class or series, as applicable, is required to authorize a given action of the Corporation, the affirmative vote or consent of the Holders of at least a majority of the then outstanding shares of the Series E Preferred Stock represented at a duly held meeting at which a quorum is present or by written consent of the Holders of at least a majority of the then outstanding shares of Series E Preferred Stock shall constitute the approval of such action by the class.

(b) Election of Directors. So long as any shares of Series E Preferred Stock remain outstanding, the Board of Directors will consist of five (5) members, one of which shall be the Chief Executive Officer, or similar position, of the Corporation and one of which shall be nominated by the holders of shares of Series E Preferred Stock, voting separately as a single class (the “Series E Director Nominee”), which director may be removed from office, and any vacancy caused by the resignation, death or removal of the Series E Director Nominee shall be filled by the holders of a majority of the then outstanding shares of Series E Preferred Stock.

9. Protective Provisions. So long as any of the shares of Series E Preferred Stock are outstanding, the Corporation shall not, without first obtaining the approval (by vote or written consent) of the Holders of a majority of the then outstanding shares of Series E Preferred Stock (i) amend the rights, preferences or privileges of the Series E Preferred Stock set forth in this Statement With Respect to Shares; (ii) create any new class or series of capital stock that would constitute Senior Securities or Pari Passu Securities; (iii) redeem, or declare or pay any dividend or other distribution on account of, any shares of Common Stock or Junior Securities (other than pursuant to the terms of any stock option plan for directors, officers, employees, advisors or consultants approved by the Board of Directors); (iv) amend, alter or repeal any provision of the Articles of Incorporation or Bylaws of the Corporation; (v) effect any transaction that would be deemed a Liquidation Event (as defined in Section 6(a)) or Corporate Change (as defined in Section 7(b) hereof); (vi) authorize or enter into any transaction or series or related transactions in which the holder or holders of capital stock of the Corporation immediately prior to such transaction or series of transactions will hold, immediately after such transaction or series of transactions, less than a majority of the aggregate voting power of the outstanding capital stock of the surviving entity; (vii) increase or decrease the authorized number of directors constituting the Board of Directors; (viii) decrease the number of authorized shares of Preferred Stock; (ix) redeem or offer to redeem any shares of Series E Preferred Stock; (x) authorize or effect a transaction in which the Corporation would incur any debt secured by the assets of the Corporation or amend its current secured debt facility; or (xi) enter into any transaction, other than employment or consulting agreements in the ordinary course of business on a basis consistent with past practices, with any officer, director or beneficial owner of five percent (5%) or more of the Common Stock or any affiliate of the foregoing. Notwithstanding the foregoing, no consent or approval of the Holders will be required for, and the Board of Directors is expressly authorized to provide for, the issuance of shares of Preferred Stock if such series would constitute Junior Securities, by filing a certificate pursuant to the applicable law of the

Commonwealth of Pennsylvania, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereon.

10. Miscellaneous.

(a) Cancellation of Series E Preferred Stock. If any shares of Series E Preferred Stock are converted pursuant to Section 4, the shares so converted shall be canceled, shall return to the status of authorized, but unissued Preferred Stock of no designated series, and shall not be issuable by the Corporation as Series E Preferred Stock.

(b) Lost or Stolen Certificates. Upon receipt by the Corporation of (i) evidence of the loss, theft, destruction or mutilation of any Series E Preferred Stock Certificate(s) and (ii) (y) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to the Corporation, or (z) in the case of mutilation, upon surrender and cancellation of the Series E Preferred Stock Certificate(s), the Corporation shall execute and deliver new Series E Preferred Stock Certificate(s) of like tenor and date.

Exhibit D

Statement With Respect to Shares
of
Series D Convertible Preferred Stock
of
Environmental Tectonics Corporation

Pursuant to Section 1522(b) of the
Business Corporation Law of the Commonwealth of Pennsylvania

FIRST: The name of the Corporation is Environmental Tectonics Corporation.

WHEREAS, the Articles of Incorporation of the Corporation authorizes Preferred Stock consisting of 1,000,000 shares issuable from time to time in one or more series; and

WHEREAS, the Board of Directors, acting through its Audit Committee, intends to establish a new series of Preferred Stock, called Series D Convertible Preferred Stock.

NOW, THEREFORE, BE IT RESOLVED, that pursuant to Article 6 of the Corporation’s Articles of Incorporation, the designation, rights, preferences, powers, restrictions and limitations applicable to the Series D Preferred Stock be and hereby are set forth below:

1. Designation. The designation of this series, which consists of 11,000 shares of Preferred Stock, $0.05 par value per share, is the Series D Convertible Preferred Stock (the “Series D Preferred Stock”) and the stated value shall be One Thousand U.S. Dollars ($1,000.00) per share (the “Stated Value”). The Series D Preferred Stock may be issued in one or more sub-series of Series D Preferred Stock to be designated: Series D-1 Preferred Stock, Series D-2 Preferred Stock, Series D-3 Preferred Stock, and so on and so forth, the number of shares of each such series to be determined by resolution of the Board of Directors of the Corporation, including the Series D Director Nominee (as hereinafter defined). Each sub-series of Series D Preferred Stock shall have all of the same rights, preferences and privileges as each other sub-series of Series D Preferred Stock, except that the Conversion Price (as hereinafter

defined) shall differ based on the Market Price (as hereinafter defined) on the date of issuance of such sub-series of Series D Preferred Stock.

2. Certain Definitions. For purposes of this Statement With Respect to Shares, the following terms shall have the following meanings:

“Common Stock” means the common stock of the Corporation, $0.05 par value per share.

“Conversion Price” means, with respect to each share of Series D Preferred Stock, the Market Price as of the date of issuance of such shares of Series D Preferred Stock, provided that such Conversion Price shall be subject to adjustment as provided herein.

“Market Price” means, as of any date, (i) the closing sale price for the shares of Common Stock as reported on NYSE AMEX LLC, the successor to the American Stock Exchange (“AMEX”) by Bloomberg Financial Markets (“Bloomberg”) for the trading day immediately preceding such date, or (ii) if AMEX is not the principal trading market for the shares of Common Stock, the average of the reported closing sale prices reported by Bloomberg on the principal trading market for the Common Stock during the one hundred twenty (120) day period immediately preceding such date, or (iii) if market value cannot be calculated as of such date on any of the foregoing bases, the Market Price shall be determined in good faith by the Board of Directors of the Corporation.

3. Dividends.

(a) Accruing Dividends. From and after the date a share of Series D Preferred Stock is issued (the “Applicable Issue Date”), the holder of such issued and outstanding share of Series D Preferred Stock (each a “Holder” and collectively, the “Holders”) shall be entitled to receive, out of funds legally available therefor, cumulative dividends at a rate of ten percent (10%) per annum of the Stated Value on each such share of Series D Preferred Stock (the “Accruing Dividends”) in preference to the holders of Common Stock or any other series of Preferred Stock issued by the Corporation after the date hereof which does not, by its terms, provide that it is senior to or pari passu with the Series D Preferred Stock with respect to dividends. The Accruing Dividends shall accrue on each issued and outstanding share of Series D Preferred Stock from the Applicable Issue Date, from day to day, whether or not earned or declared, and shall compound annually and be cumulative. The Corporation shall only pay the Holder the Accruing Dividends upon a Liquidation Event (as hereinafter defined) or when otherwise declared by the Board of Directors of the Corporation.

(b) The Corporation shall not declare, pay or set aside any dividends on shares of any other class or series of capital stock of the Corporation (other than dividends on shares of Common Stock payable in shares of Common Stock) unless (in addition to the obtaining of any consents required elsewhere in the Articles of Incorporation) the holders of the Series D Preferred Stock then outstanding shall first receive a dividend on each outstanding share of Series D Preferred Stock in an amount at least equal to the amount of the aggregate Accruing Dividends then accrued on such share of Series D Preferred Stock and not previously paid.

(c) The Holders shall be entitled to receive, if and when declared by the Board of Directors and paid by the Corporation, any dividends paid with respect to the Common Stock (other than any dividends paid in additional shares of Common Stock). In the case of any such dividend, each Holder shall be entitled to receive an amount per share of Series D Preferred Stock held by such Holder as of the record date for such dividend equal to the product of: (i) the amount of the dividend payable with respect to one share of Common Stock and (ii) the number of shares of Common Stock that would be issued to a Holder if one share of Series D Preferred Stock were converted by the Holder on the record date.

4. Conversion.

(a) Conversion at the Option of the Holder. Each Holder may, at any time and from time to time, convert (an “Optional Conversion”) each of its shares of Series D Preferred Stock plus all accrued but unpaid Accruing Dividends into a number of fully paid and nonassessable shares of the Common Stock determined by dividing the Stated Value plus the aggregate amount of the Accruing Dividends by the Conversion Price for such shares of Series D Preferred Stock.

(b) Mechanics of Conversion. In order to effect an Optional Conversion, a Holder shall: (x) fax (or otherwise deliver) a copy of the fully executed Notice of Conversion to the Corporation or the transfer agent for the Common Stock and (y) surrender or cause to be surrendered the original certificates representing the Series D Preferred Stock being converted (the “Series D Preferred Stock Certificates”), duly endorsed, along with a copy of the Notice of Conversion as soon as practicable thereafter to the Corporation or the transfer agent. Upon receipt by the Corporation of a facsimile copy of a Notice of Conversion from a Holder, the Corporation shall promptly send, via facsimile, a confirmation to such Holder stating that the Notice of Conversion has been received, the date upon which the Corporation expects to deliver the Common Stock issuable upon such conversion and the name and telephone number of a contact person at the Corporation regarding the conversion. The Corporation shall not be obligated to issue shares of Common Stock upon a conversion unless either the Series D Preferred Stock Certificates are delivered to the Corporation or the transfer agent as provided above, or the Holder notifies the Corporation or the transfer agent that such Series D Preferred Stock Certificates have been lost, stolen or destroyed and delivers the documentation to the Corporation required by Section 10(b) hereof.

(i) Delivery of Common Stock Upon Conversion. Upon the surrender of Series D Preferred Stock Certificates accompanied by a Notice of Conversion, the Corporation shall, no later than the later of (a) the third (3^rd) business day following the Conversion Date and (b) the (2^nd) second business day following the date of such surrender (or, in the case of lost,

stolen or destroyed certificates, after provision of indemnity pursuant to Section 10(b)) (the “Delivery Period”), issue and deliver to the Holder or its nominee (x) that number of shares of Common Stock issuable upon conversion of such shares of Series D Preferred Stock and Accruing Dividends being converted and (y) a certificate representing the number of shares of Series D Preferred Stock not being converted, if any. If the Corporation’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend and the Holder thereof is not then required to return such certificate for the placement of a legend thereon, the Corporation shall cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Holder by crediting the account of the Holder or its nominee with DTC through its Deposit Withdrawal Agent Commission system (“DTC Transfer”). If the aforementioned conditions to a DTC Transfer are not satisfied, the Corporation shall deliver to the Holder physical certificates representing the Common Stock issuable upon conversion. Further, a Holder may instruct the Corporation to deliver to the Holder physical certificates representing the Common Stock issuable upon conversion in lieu of delivering such shares by way of DTC Transfer.

(ii) No Fractional Shares. If any conversion of Series D Preferred Stock would result in the issuance of a fractional share of Common Stock, such fractional share shall be disregarded, and the number of shares of Common Stock issuable upon conversion of the Series D Preferred Stock shall be rounded off to the nearest whole number of shares.

5. Rank. The Series D Preferred Stock shall rank (i) prior to the Common Stock; (ii) prior to the Series B Preferred Stock; (iii) prior to the Series C Preferred Stock; (iv) prior to any class or series of capital stock of the Corporation hereafter created that does not, by its terms, rank senior to or pari passu with the Series D Preferred Stock (collectively with the Common Stock, the Series B Preferred Stock and the Series C Preferred Stock, “Junior Securities”); (v) pari passu with any class or series of capital stock of the Corporation hereafter created that, by its terms, ranks on parity with the Series D Preferred Stock (the “Pari Passu Securities”); and (vi) junior to any class or series of capital stock of the Corporation hereafter created that, by its terms, ranks senior to the Series D Preferred Stock (collectively, the “Senior Securities”), in each case as to distribution of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary.

6. Liquidation Preference.

(a) If the Corporation shall commence a voluntary case under the U.S. federal bankruptcy laws or any other applicable bankruptcy, insolvency or similar law, or consent to the entry of an order for relief in an involuntary case under any law or to the appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or other similar official) of the Corporation or of any substantial part of its property, or make an assignment for the benefit of its creditors, or admit in writing its inability to pay its debts generally as they become due, or if a decree or order for relief in respect of the Corporation shall be entered by a court having jurisdiction in the premises in an involuntary case under the U.S. federal bankruptcy laws or any other applicable bankruptcy, insolvency or similar law resulting in the appointment of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or other similar official) of the Corporation or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and any such decree or order shall be unstayed and in effect for a period of ninety (90) consecutive days and, on account of any such event, the Corporation shall liquidate, dissolve or wind up, or if the Corporation shall otherwise liquidate, dissolve or wind up (a “Liquidation Event”), no distribution shall be made to the holders of any shares of Junior Securities upon liquidation, dissolution or winding up of the Corporation unless prior thereto the Holders shall have received the Liquidation Preference (as defined below) with respect to each share of Series D Preferred Stock then outstanding. Any acquisition of the Corporation by means of a merger or other form of corporate reorganization approved by the Board of Directors of the Corporation in which all outstanding shares of Common Stock are exchanged for securities or other consideration issued by the acquiring corporation or its subsidiary or the effectuation by the Corporation of a transaction or series of related transactions approved by the Board of Directors of the Corporation in which more than 50% of the voting power is disposed of or the sale, lease or other disposition of all or substantially all of the assets of the Corporation, shall be deemed a Liquidation Event unless the holders of a majority of the outstanding shares of Series D Preferred Stock elect to the contrary; such election to be made by giving written notice thereof to the Corporation at least three (3) days before the closing of such event. For clarification, none of the transactions described in the preceding sentence shall be deemed a Liquidation Event unless any such transaction is approved by the Board of Directors of the Corporation. In such event, the Holders will be entitled to receive in preference to the holders of Junior Securities, the Liquidation Preference with respect to shares of Series D Preferred Stock in the form of cash, securities or other property as is payable in connection with the transaction deemed to be a Liquidation Event. In the event that the Corporation sells, conveys or disposes of all or substantially all of its assets, the Holders will be entitled to receive, prior to the holders of the Junior Securities, if and when the Board of Directors declares a distribution of the consideration received by the Corporation in such asset sale, the Liquidation Preference with respect to the shares of Series D Preferred Stock. If, upon the occurrence of a Liquidation Event, the assets and funds available for distribution among the Holders and holders of Pari Passu Securities shall be insufficient to permit the payment to such holders of the preferential amounts payable thereon, then the entire assets and funds of the Corporation legally available for distribution to the Series D Preferred Stock and the Pari Passu Securities, if any, shall be distributed ratably among such shares in proportion to the ratio that the Liquidation Preference payable on each such share bears to the aggregate Liquidation Preference payable on all such shares. Following payments of preferences to all holders of preferred stock of the Corporation, all remaining assets and funds of the Corporation legally available for distribution shall be distributed ratably to the

holders of Common Stock, Series D Preferred Stock (on an as-if converted to Common Stock basis) and any other capital stock of the Corporation entitled to share in such distribution.

(b) The “Liquidation Preference” with respect to a share of Series D Preferred Stock means an amount equal to the Stated Value thereof plus any accrued and unpaid dividends thereon, including the Accruing Dividends. The Liquidation Preference with respect to any Pari Passu Securities shall be as set forth in the Statement With Respect to Shares filed in respect thereof.

7. Adjustments to the Conversion Price. The Conversion Price shall be subject to adjustment from time to time as follows:

(a) Stock Splits, Stock Dividends, Etc. If, at any time on or after the date hereof, the number of outstanding shares of Common Stock is increased by a stock split, stock dividend, combination, reclassification or other similar event, the Conversion Price for each share of Series D Preferred Stock shall be proportionately reduced, or if the number of outstanding shares of Common Stock is decreased by a reverse stock split, combination or reclassification of shares, or other similar event, the Conversion Price for each share of Series D Preferred Stock shall be proportionately increased.

(b) Adjustment Due to Merger, Consolidation, Etc. If, at any time after the date hereof, there shall be (i) any reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) any consolidation or merger of the Corporation with any other entity (other than a merger in which the Corporation is the surviving or continuing entity and its capital stock is unchanged), (iii) any sale or transfer of all or substantially all of the assets of the Corporation or (iv) any share exchange pursuant to which all of the outstanding shares of Common Stock are converted into other securities or property (each of (i) - (iv) above being a “Corporate Change”), and, if such Corporate Change is not a Liquidation Event pursuant to the terms of Section 6(a), then the Holders shall thereafter have the right to receive upon conversion, in lieu of the shares of Common Stock otherwise issuable, such shares of stock, securities and/or other property as would have been issued or payable in such Corporate Change with respect to or in exchange for the number of shares of Common Stock which would have been issuable upon conversion had such Corporate Change not taken place, and in any such case, appropriate provisions (in form and substance reasonably satisfactory to the Holders of a majority of the Series D Preferred Stock then outstanding) shall be made with respect to the rights and interests of the Holders to the end that the economic value of the shares of Series D Preferred Stock are in no way diminished by such Corporate Change and that the provisions hereof (including, without limitation, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is not the Corporation, an immediate adjustment of the Conversion Price for each share of Series D Preferred Stock so that the Conversion Price immediately after the Corporate Change reflects the same relative value as compared to the value of the surviving entity’s common stock that existed between the Conversion Price and the value of the Common Stock immediately prior to such Corporate Change).

(i) Weighted Average Anti-Dilution Formula.

(A) If the Corporation issues, after the date hereof (the “Effective Date”), any Additional Stock (as defined below) without consideration or for a consideration per share less than the Conversion Price for any sub-series of the Series D Preferred Stock in effect immediately prior to the issuance of such Additional Stock, the Conversion Price for such sub-series of the Series D Preferred Stock in effect immediately prior to each such issuance shall forthwith (except as otherwise provided in this Section 7(c)(i)) be reduced to a price determined in accordance with the following formula:

CP2 = CP1 * (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(1) “CP2” shall mean the Conversion Price for the Series D Preferred Stock in effect immediately after such issue of Additional Stock

(2) “CP1” shall mean the Conversion Price of the Series D Preferred Stock in effect immediately prior to such issue of Additional Stock;

(5) “C” shall mean the number of such Additional Stock issued in such transaction.

(B) No adjustment of the Conversion Price for any series of Series D Preferred Stock will be made in an amount less than one cent per share, provided that any adjustments that are not required to be made by reason of this sentence will be carried forward and shall be either taken into account in any subsequent adjustment made prior to three (3) years from the date of the event giving rise to the adjustment being carried forward, or will be made at the end of three (3) years from the date of the event giving rise to the adjustment being carried forward. Except to the limited extent provided for in Sections 7(c)(i)(E)(3) and 7(c)(i)(E)(4), no adjustment of such Conversion Price pursuant to this Section 7(c)(i) shall have the effect of increasing the Conversion Price above the Conversion Price in effect immediately prior to such adjustment.

(1) The aggregate maximum number of shares of Common Stock deliverable upon exercise (to the extent then exercisable) of such warrants, options to purchase or rights to subscribe for Common Stock will be deemed to have been issued at the time such warrants, options or rights were issued and for a consideration equal to the consideration (determined in the manner provided in Sections 7(c)(i)(C) and 7(c)(i)(D)), if any, received by the Corporation upon the issuance of such warrants, options or rights plus the minimum exercise price provided in such warrants, options or rights the Common Stock covered thereby.

(3) In the event of any change in the number of shares of Common Stock deliverable or in the consideration payable to the Corporation upon exercise of such options or rights or upon conversion of or in exchange for such convertible or exchangeable securities, including, but not limited to, a change resulting from the antidilution provisions thereof, the Conversion Price of the Series D Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities, will be recomputed to reflect such change, but no further adjustment will be made for the

actual issuance of Common Stock or any payment of such consideration upon the exercise of any such options or rights or the conversion or exchange of such securities.

(4) Upon the expiration of any such options or rights, the termination of any such rights to convert or exchange or the expiration of any options or rights related to such convertible or exchangeable securities, the Conversion Price of the Series D Preferred Stock, to the extent in any way affected by or computed using such options, rights or securities or options or rights related to such securities, will be recomputed to reflect the issuance of only the number of shares of Common Stock (and convertible or exchangeable securities that remain in effect) actually issued upon the exercise of such options or rights, upon the conversion or exchange of such securities or upon the exercise of the options or rights related to such securities.

(a) shares of Common Stock issued pursuant to a transaction described in Section 7(a) hereof;

(f) shares of Common Stock issuable upon conversion of any shares of any sub-series of Series D Preferred Stock;

(g) shares of Common Stock issuable upon exercise of those certain warrants to purchase common stock issued or issuable in connection with the transactions contemplated by that certain Secured Credit Facility and Warrant Purchase Agreement dated as of April ___, 2009 by and between the Corporation and H.F. Lenfest ) (the “2009 Purchase Agreement”);

(h) shares of Preferred Stock issued to H.F. Lenfest (or his designee) pursuant to the terms of the 2009 Purchase Agreement; or

8. Voting Rights.

(a) General. The Holders shall be entitled to vote with the holders of Common Stock, voting together as one class, on all matters submitted to a vote of the holders of Common Stock, and each share of Series D Preferred Stock shall be entitled to a number of votes equal to the number of shares of Common Stock into which each such share is convertible as of the record date for the applicable vote. To the extent that under the Pennsylvania Business Corporation Law the vote of the Holders, voting separately as a class or series, as applicable, is required to authorize a given action of the Corporation, the affirmative vote or consent of the Holders of at least a majority of the then outstanding shares of Series D Preferred Stock represented at a duly held meeting at which a quorum is present or by written consent of the Holders of at least a majority of the then outstanding shares of Series D Preferred Stock shall constitute the approval of such action by the class. On all matters submitted to vote or consent of the holders of Series D Preferred Stock, all sub-series of Series D Preferred Stock shall vote together as one class.

(b) Election of Directors. So long as any shares of Series D Preferred Stock remain outstanding, the Board of Directors will consist of five (5) members, one of which shall be the Chief Executive Officer, or similar position, of the Corporation and one of which shall be nominated by the holders of shares of Series D Preferred Stock, voting separately as a single class (the “Series D Director Nominee”), which director may be removed from office, and any vacancy caused by the resignation, death or removal of the Series D Director Nominee shall be filled by the holders of a majority of the then outstanding shares of Series D Preferred Stock.

9. Protective Provisions. So long as any of the shares of Series D Preferred Stock are outstanding, the Corporation shall not, without first obtaining the approval (by vote or written

consent) of the Holders of a majority of the then outstanding shares of Series D Preferred Stock (i) amend the rights, preferences or privileges of the Series D Preferred Stock set forth in this Statement With Respect to Shares; (ii) create any new class or series of capital stock that would constitute Senior Securities or Pari Passu Securities (except as contemplated under the terms of the 2009 Purchase Agreement); (iii) redeem, or declare or pay any dividend or other distribution on account of, any shares of Common Stock or Junior Securities (other than pursuant to the terms of any stock option plan for directors, officers, employees, advisors or consultants approved by the Board of Directors); (iv) amend, alter or repeal any provision of the Articles of Incorporation or Bylaws of the Corporation; (v) effect any transaction that would be deemed a Liquidation Event (as defined in Section 6(a)) or Corporate Change (as defined in Section 7(b) hereof); (vi) authorize or enter into any transaction or series or related transactions in which the holder or holders of capital stock of the Corporation immediately prior to such transaction or series of transactions will hold, immediately after such transaction or series of transactions, less than a majority of the aggregate voting power of the outstanding capital stock of the surviving entity; (vii) increase or decrease the authorized number of directors constituting the Board of Directors; (viii) decrease the number of authorized shares of Preferred Stock; (ix) redeem or offer to redeem any shares of Series D Preferred Stock; (x) authorize or effect a transaction in which the Corporation would incur any debt secured by the assets of the Corporation or amend its current secured debt facility; or (xi) enter into any transaction, other than employment or consulting agreements in the ordinary course of business on a basis consistent with past practices, with any officer, director or beneficial owner of five percent (5%) or more of the Common Stock or any affiliate of the foregoing. Notwithstanding the foregoing, no consent or approval of the Holders will be required for, and the Board of Directors is expressly authorized to provide for, the issuance of shares of Preferred Stock if such series would constitute Junior Securities, by filing a certificate pursuant to the applicable law of the Commonwealth of Pennsylvania, to establish from time to time the number of shares to be included in each such series, and to fix the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereon.

10. Miscellaneous.

(a) Cancellation of Series D Preferred Stock. If any shares of Series D Preferred Stock are converted pursuant to Section 4, the shares so converted shall be canceled, shall return to the status of authorized, but unissued Preferred Stock of no designated series, and shall not be issuable by the Corporation as Series D Preferred Stock.

(b) Lost or Stolen Certificates. Upon receipt by the Corporation of (i) evidence of the loss, theft, destruction or mutilation of any Series D Preferred Stock Certificate(s) and (ii) (y) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to the Corporation, or (z) in the case of mutilation, upon surrender and cancellation of the Series D Preferred Stock Certificate(s), the Corporation shall execute and deliver new Series D Preferred Stock Certificate(s) of like tenor and date. However, the Corporation shall not be obligated to reissue such lost or stolen Series D Preferred Stock Certificate(s) if the Holder contemporaneously requests the Corporation to convert such Series D Preferred Stock.

(c) Status as Shareholder. Upon submission of a Notice of Conversion by a Holder, (i) the shares covered thereby and any accrued and unpaid Accruing Dividends thereon

shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a holder of such converted shares of Series D Preferred Stock shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Corporation to comply with the terms of this Statement With Respect to Shares.

THIRD: With respect to the Series D Preferred Stock, the aggregate number of shares of such class or Series established and designated by (a) such resolutions, (b) all prior statements, if any, filed under 15 Pa.

The Lender shall have no obligation or liability under any Account (or any agreement giving rise thereto) or under any Contract by reason of or arising out of this Agreement or the receipt by the Lender of any payment relating to such Account or Contract pursuant hereto, nor shall the Lender be obligated in any manner to perform any of the obligations of the Debtors under or pursuant to any Account (or any agreement giving rise thereto) or under or pursuant to any Contract, to make any payment, to make any inquiry as to the nature or the sufficiency of any payment received by it or as to the sufficiency of any performance by any party under any Account (or any agreement giving rise thereto) or under any Contract, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to it or to which it may be entitled at any time or times.

(b) Notice to Account Debtors and Contracting Parties. Upon the request of the Lender at any time after the occurrence and during the continuance of an Event of Default, the Debtors shall notify account debtors on the Accounts and parties to the Contracts that the Accounts and the Contracts have been assigned to the Lender and shall indicate on all billings that payments in respect thereof shall be made directly to the Lender. The Lender may in the name of the Debtors or in the name of others communicate with account debtors on the Accounts and parties to the Contracts to verify with them to its satisfaction the existence, amount and terms of any Accounts or Contracts.

(c) Analysis of Accounts. The Lender shall have the right to make test verifications of the Accounts through periodic site visits as provided in Section 7.1(i) of the Purchase Agreement, and the Debtors shall furnish all such assistance and information as the

Lender may reasonably require in connection therewith. At any time, and from time to time, but in no event more than twice in any given twelve month period, upon the Lender’s request and at the expense of the Debtors, the Debtors shall cause independent public accountants or others satisfactory to the Lender to furnish to the Lender reports showing reconciliations, aging and test verifications of, and trial balances for, the Accounts; provided that any such reconciliation, aging or test verification performed at the request of PNC Bank, National Association (“PNC”) and delivered to the Lender shall satisfy a like request from the Lender if made within six (6) months of the request from PNC.

(d) Collections on Accounts. Subject to the further provisions of this Section 3(d), the Lender hereby authorizes the Debtors to collect the Accounts from the account debtors. Prior to the occurrence of an Event of Default, the Proceeds of Accounts so collected by the Debtors shall be received and held by the Debtors in trust for the Lender but may be applied by the Debtors in their discretion towards payment of the Obligations or other corporate purposes. Upon the occurrence of an Event of Default which has not been waived by or cured to the satisfaction of the Lender and subject to the direction of the Lender, (i) the authority hereby given to the Debtors to collect the Proceeds of Accounts may be terminated by the Lender at any time and after being notified of such termination, the Debtors shall deliver to the Lender on the date of receipt thereof by the Debtors all Proceeds in the form of cash, checks, drafts, notes and other remittances received in payment of or on account of the Debtors’ Accounts; (ii) following receipt by the Lender any such Proceeds shall be deposited in a special bank account (the “Cash Collateral Account”) of the Debtors maintained at a commercial bank chosen by the Lender over which the Lender alone shall have power of withdrawal; (iii) all Proceeds other than cash shall be deposited in precisely the form in which received, except for the addition thereto of the endorsement of the Debtors when necessary to permit collection of the items, which endorsement the Debtors agree to make; and (iv) the Debtors will not commingle any such Proceeds with any of the Debtors’ other funds or property but will hold them separate and apart from any other funds or property and upon an express trust for the Lender until deposit thereof is made in the Cash Collateral Account.

4. Representations and Warranties. The Debtors hereby jointly and severally represent and warrant that:

(a) Title; No Other Liens. Except for the Liens granted hereby, the Liens granted to PNC pursuant to the PNC Security Agreement and any other Permitted Liens, one or more of the Debtors own each item of the Collateral free and clear of any and all Liens or claims of others. No security agreement, financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except such as may have been filed in favor of the Lender, pursuant to this Agreement or as may be permitted pursuant to the Purchase Agreement.

(b) Perfected Second Priority Liens. Upon the Lender taking all action necessary under the UCC to perfect its security interest in and to the Collateral, the Liens granted pursuant to this Agreement constitute perfected Liens on the Collateral in favor of the Lender, which are prior to all other Liens on the Collateral in existence on the date hereof (other than Permitted Liens) and are enforceable as such against all creditors of and purchasers from the

Debtors and against any owner or purchaser of the real property where any of the Equipment is located and any present or future creditor obtaining a Lien on such real property.

(c) Accounts. The amount represented by the Debtors to the Lender in any accounts receivable aging and in other reports requested by or furnished to the Lender as owing by each account debtor or by all account debtors in respect of the Accounts will at such time be the correct amount actually owing by such account debtor or debtors thereunder except for normal cash discounts and allowances where applicable. No amount payable to the Debtors under or in connection with any Account is evidenced by any Instrument or Chattel Paper which has not been delivered to the Lender. The Debtors keep their records concerning the Accounts at the location or locations set forth in Schedule IV.

(d) Contracts. Except as contemplated hereby, no consent of any party (other than the Debtors) to any material Contract is required, or purports to be required, in connection with the execution, delivery and performance of this Agreement. Each material Contract is in full force and effect and constitutes a valid and legally enforceable obligation of the parties thereto, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditor’s rights generally. No consent or authorization of, filing with or other act by or in respect of any Governmental Authority is required in connection with the execution, delivery, performance, validity or enforceability of any of the Contracts by any party thereto other than those which have been duly obtained, made or performed, are in full force and effect and do not subject the scope of any such Contract to any material adverse limitation, either specific or general in nature. Neither the Debtors nor (to the best of the Debtors’ knowledge) any other party to any Contract are in default of any material provision thereof or are likely to become in default in the performance or observance of any of the material provisions thereof. The Debtors have fully performed all their material obligations under each Contract. The right, title and interest of each Debtor in, to and under each Contract to which such Debtor is a party are not subject to any defense, offset, counterclaim or claim which would materially adversely affect the value of such Contract as Collateral, nor have any of the foregoing been asserted or alleged against the Debtors as to any Contract. No amount payable to the Debtors under or in connection with any Contract is evidenced by any Instrument or Chattel Paper which has not been delivered to the Lender.

(e) Inventory. The types, amounts and valuations of the Inventory or any other information regarding the same represented by the Debtors in any reports requested by or furnished to the Lender, or any other holders of the Obligations will at such time be accurate to the best of the Debtors’ knowledge. The Debtors keep records concerning the Inventory at the location or locations listed on Schedule V.

Schedule II hereto includes all Patents and Patent Licenses owned by each of the Debtors in its own name as of the date hereof. Schedule III hereto includes all Trademarks and Trademark Licenses owned by each of the Debtors in its own name as of the date hereof. To the best of the Debtors’ knowledge, each Copyright, Patent and Trademark is valid, subsisting, unexpired, enforceable and has not been abandoned. Except as set forth in any such Schedule, none of such Copyrights, Patents or Trademarks is the subject of any licensing or franchise agreement. No holding, decision or judgment has been rendered by any Governmental Authority which would limit, cancel or question the validity of any Copyright, Patent or Trademark. Except as set forth in any such Schedule, no action or proceeding is pending (i) seeking to limit, cancel or question the validity of any Copyright, Patent or Trademark, or (ii) which, if adversely determined, would have a material adverse effect on the value of any Copyright, Patent or Trademark.

(j) Power and Authority; Authorization. The Debtors have the corporate or other power and authority and the legal right to execute and deliver, to perform their obligations under, and to grant the Liens on the Collateral pursuant to, this Agreement and have taken all necessary corporate or other action to authorize its execution, delivery and performance of, and grant of the Liens on the Collateral pursuant to, this Agreement.

This Agreement constitutes a legal, valid and binding obligation of each of the Debtors enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally.

(l) No Conflict. The execution, delivery and performance of this Agreement will not violate any provision of any Law or any obligation under any agreement, instrument, document or contract to which any of the Debtors is a party (each, a “Contractual Obligation”) and will not result in the creation or imposition of any Lien on any of the properties or revenues of any of the Debtors pursuant to any Law or Contractual Obligation of any of the Debtors, except as contemplated hereby.

(m) No Consents, etc. Except as contemplated hereby, no consent or authorization of, filing with, or other act by or in respect of, any arbitrator or Governmental Authority and no consent of any other Person (including, without limitation, any stockholder or creditor of any of the Debtors), is required in connection with the execution, delivery, performance, validity or enforceability of this Agreement (except for the filing of the UCC financing statements).

(n) No Litigation. Except as set forth on Schedule 5.1(j) to the Purchase Agreement, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Debtors, threatened by or against any of the

Debtors or against any of its properties or revenues with respect to this Agreement or any of the transactions contemplated hereby.

5. Covenants. Each of the Debtors covenants and agrees with the Lender that, from and after the date of this Agreement until the Obligations are paid in full and the Credit Facility is terminated, it will:

(a) Notices; Further Documentation; Authorization to File Financing Statements. Notify the Lender in writing at any time that it opens, acquires, obtains, or becomes the beneficiary of any type of Collateral (or rights therein) to the extent the Lender will not at that time have, and continuously thereafter (subject to the filing of continuation statements, if necessary) maintain, a perfected priority security interest in (subject to solely Permitted Liens) such Collateral, including but not limited to: all Deposit Accounts, Securities Accounts and Commodity Accounts and other Investment Property; all Commercial Tort Claims; all Instruments, Documents, Tangible Chattel Paper and Electronic Chattel Paper; all other Collateral in the possession of a third party; and all Letter-of-Credit Rights and other Supporting Obligations.

The Debtors will mark all Chattel Paper with a legend indicating that the Lender has a security interest in the Chattel Paper.

The Debtors also hereby authorize the Lender to file any Uniform Commercial Code financing or continuation statement without the signature of the Debtors to the extent permitted by applicable law. The Debtors hereby ratify any filing by the Lender of financing statements prior to the date hereof with respect to the Collateral. A carbon, photographic, facsimile or other reproduction of this Agreement shall be sufficient as a financing statement for filing in any jurisdiction.

(b) Indemnification. Pay, and save the Lender and any other holders of the Obligations harmless from, any and all liabilities, reasonable costs and expenses (including, without limitation, reasonable legal fees and expenses) (i) with respect to, or resulting from, any delay in paying any and all excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral, (ii) with respect to, or resulting from, any delay in complying with any Law applicable to any of the Collateral or (iii) in connection with protecting, storing, warehousing, appraising, insuring, handling, maintaining and shipping the Collateral, all reasonable costs, fees and expenses of creating, perfecting, maintaining and enforcing the security interests created by this Agreement, and any and all excise, property, sales and use taxes imposed by any federal, state, local or foreign authority on any of the Collateral, or with respect

to periodic appraisals and inspections of the Collateral, or with respect to the sale or other disposition thereof. In any suit, proceeding or action brought by the Lender under any Account or Contract for any sum owing thereunder, or to enforce any provisions of any Account or Contract, the Debtors will save, indemnify and keep the Lender harmless from and against all expense, loss or damage suffered by reason of any defense, setoff, counterclaim, recoupment or reduction of liability whatsoever of the account debtor or obligor thereunder, arising out of a breach by the Debtors of any obligation thereunder or arising out of any other agreement, indebtedness or liability at any time owing to or in favor of such account debtor or obligor or its successors from the Debtors; provided, however, that such expense, loss or damage does not arise from the gross negligence or willful misconduct of the Lender.

(c) Maintenance of Records. Keep and maintain at its own cost and expense true, correct and complete records of the Collateral, including, without limitation, a record of all payments received and all credits granted with respect to the Accounts. For the Lender’s further security, the Lender shall have a security interest in the Debtors’ books and records pertaining to the Collateral, and the Debtors shall turn over copies of any such books and records to the Lender or to its representatives during normal business hours at the request of the Lender.

(d) Right of Inspection and Audit. Give to the Lender, no more than two (2) times during any twelve (12) month period, upon reasonable prior notice full and free access during normal business hours (or following the occurrence and during the continuance of an Event of Default, at any time) to all of its books, correspondence and records and the Lender and its respective representatives may examine, inspect or audit the same, take extracts therefrom and make photocopies thereof, and the Debtors agree to render to the Lender, at the Debtors’ cost and expense, such clerical and other assistance as may be reasonably requested with regard thereto. The Lender and its respective representatives shall at all times during normal business hours (or following the occurrence of an Event of Default, at any time) also have the right without breach of the peace to enter into and upon any premises where any of the Inventory or Equipment is located for the purpose of examining, inspecting or auditing the same, observing its use or otherwise protecting their interests therein.

(e) Compliance with Laws, etc. Comply in all material respects with all Laws applicable to the Collateral or any part thereof or to the operation of its business; provided, however, that the Debtors may contest any Law in any reasonable manner which shall not, in the sole opinion of the Lender, adversely affect the Lender’s rights or the priority of his Liens on the Collateral.

(f) Compliance with Terms of Contracts, etc. Perform and comply in all material respects with all of its material obligations under the Contracts and all of its other Contractual Obligations relating to the Collateral.

(g) Payment of Obligations. Pay promptly when due all taxes, assessments and governmental charges or levies imposed upon the Collateral or in respect of its income or profits therefrom, as well as all claims of any kind (including, without limitation, claims for labor, materials and supplies) against or with respect to the Collateral, except that no such charge need be paid if (i) the validity thereof is being contested in good faith by appropriate proceedings, (ii) such proceedings do not involve any material danger of the sale, forfeiture or

loss of any of the Collateral or any interest therein and (iii) such charge is adequately reserved against on the Debtors’ books in accordance with GAAP.

(h) Limitation on Liens on Collateral. Not create, incur or permit to exist, will defend the Collateral against, and take such other action as is necessary to remove, any Lien or claim on or to the Collateral, other than the Permitted Liens, and will defend the right, title and interest of the Lender in and to any of the Collateral against the claims and demands of all Persons whomsoever.

Not adjust, settle or compromise the amount or payment of any Account, or release wholly or partly any customer or obligor thereof, or allow any credit or discount thereon (other than adjustments, settlements, compromises, releases, credits and discounts in the ordinary course of business and in amounts which are not material to the Debtors) without the prior consent of the Lender.

(k) Further Identification of Collateral. Furnish to the Lender, from time to time, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as the Lender may reasonably request, all in reasonable detail.

(l) Notices. Advise the Lender promptly, in reasonable detail, at its address set forth in the Purchase Agreement, (i) of any Lien (other than Permitted Liens) on, or claim asserted against, any of the Collateral and (ii) of the occurrence of any other event which could reasonably be expected to have a material adverse effect on the aggregate value of the Collateral or on the Liens created hereunder.

(m) Changes in Locations, Name, Place of Organization, etc. Unless it shall have given the Lender at least 30 days prior written notice thereof, none of the Debtors will (i) change the location of its chief executive office or chief place of business from that specified in Schedule VIII attached hereto or remove its books and records from the location specified in Section 4(g), (ii) permit any of the Inventory or Equipment to be kept at a location other than those listed on Schedule VI and Schedule VII hereto, (iii) change its name, identity or corporate structure to such an extent that any financing statement filed by the Lender in connection with this Agreement would become seriously misleading or (iv) change the state of its organization.

(n) Patents, Trademarks and Copyrights.

(i) Unless any of the Debtors deems it appropriate in the exercise of its reasonable business judgment to do otherwise and, if after the occurrence of an Event of Default which has not been waived or cured to the satisfaction of the Lender with the prior written consent of the Lender, (i) continue to use each Trademark on each and every trademark class of goods applicable to its current line as reflected in its current catalogs, brochures and price lists in order to maintain such Trademark in full force free from any claim of abandonment

for non-use, (ii) maintain as in the past the quality of products and services offered under such Trademark, (iii) employ such Trademark or Copyright with the appropriate notice of registration, (iv) not adopt or use any mark which is confusingly similar or a colorable imitation of such Trademark unless the Lender shall obtain a perfected security interest in such mark pursuant to this Agreement, and (v) not (and not permit any licensee or sublicensee thereof to) do any act or knowingly omit to do any act whereby any Trademark or Copyright may become invalidated.

(ii) Not, unless any of the Debtors deems it appropriate in the exercise of its reasonable business judgment to do otherwise and, if after the occurrence of an Event of Default which has not been waived by or cured to the satisfaction of the Lender with the prior written consent of the Lender, do any act, or omit to do any act, whereby any Patent may become abandoned or dedicated.

(iii) Notify the Lender immediately if it knows, or has reason to know, that any application or registration relating to any Patent, Trademark or Copyright may become abandoned or dedicated, or of any adverse determination or development (including, without limitation, the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any court or tribunal in any country) regarding its ownership of any Patent, Trademark or Copyright or its right to register the same or to keep and maintain the same.

(iv) Whenever any of the Debtors, either by itself or through any agent, employee, licensee or designee, shall file an application for the registration of any Patent, Trademark or Copyright with the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency in any other country or any political subdivision thereof, report such filing to the Lender within five (5) Business Days after the last day of the fiscal quarter in which such filing occurs. Upon request of the Lender, the Debtors shall execute and deliver any and all agreements, instruments, documents, and papers as the Lender may request to evidence the Lender’s security interest in any Patent, Trademark or Copyright and the goodwill and general intangibles of the Debtors relating thereto or represented thereby, and the Debtors hereby constitute the Lender, its attorney-in-fact to execute and file all such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power being coupled with an interest is irrevocable until the Obligations are paid in full and the Credit Facility is terminated.

(v) Take all reasonable and necessary steps, including, without limitation, in any proceeding before the United States Patent and Trademark Office, the United States Copyright Office or any similar office or agency in any other country or any political subdivision thereof, to maintain and pursue each application (and to obtain the relevant registration) and to maintain each registration of the Patents, Trademarks and Copyrights, including, without limitation, filing of applications for renewal, affidavits of use and affidavits of incontestability.

(vi) In the event that any Patent, Trademark or Copyright included in the Collateral is materially infringed, misappropriated or diluted by a third party, promptly notify the Lender after it learns thereof and shall, unless it shall reasonably determine that such Patent, Trademark or Copyright is of negligible economic value to it, which determination it shall

promptly report to the Lender, promptly sue for infringement, misappropriation or dilution, to seek injunctive relief where appropriate and to recover any and all damages for such infringement, misappropriation or dilution, or take such other actions as it shall reasonably deem appropriate under the circumstances to protect such Patent, Trademark or Copyright.

6. Lender’s Appointment as Attorney-in-Fact.

(a) Powers. The Debtors hereby irrevocably constitute and appoint the Lender and any agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Debtors and in the name of the Debtors or in its own name, from time to time in the Lender’s discretion, for the purpose of carrying out the terms of this Agreement, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, the Debtors hereby give the Lender the power and right, on behalf of the Debtors, without notice to or assent by the Debtors, to do the following:

(i) in the case of any Account, at any time when the authority of the Debtors to collect the Accounts has been curtailed or terminated pursuant to Section 3(d) hereof, or in the case of any other Collateral, at any time when any Event of Default shall have occurred and is continuing, in the name of the Debtors or its own name, or otherwise, to take possession of and indorse and collect any checks, drafts, notes, acceptances or other instruments for the payment of moneys due under any Account, Instrument, General Intangible or Contract or with respect to any other Collateral and to file any claim or to take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Lender for the purpose of collecting any and all such moneys due under any Account, Instrument, General Intangible or Contract or with respect to any other Collateral whenever payable;

(ii) to pay or discharge taxes and Liens levied or placed on or threatened against the Collateral (other than Permitted Liens), to effect any repairs or procure any insurance called for by the terms of this Agreement and to pay all or any part of the premiums therefor and the costs thereof;

(iii) upon the occurrence and during the continuance of any Event of Default, (A) to direct any party liable for any payment under any of the Collateral to make payment of any and all moneys due or to become due thereunder directly to the Lender or as the Lender shall direct; (B) to ask or demand for, collect, receive payment of and receipt for, any and all moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral; (C) to sign and indorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts, drafts against debtors, assignments, verifications, notices and other documents in connection with any of the Collateral; (D) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any proceeds thereof and to enforce any other right in respect of any Collateral; (E) to defend any suit, action or proceeding brought against the Debtors or any of them with respect to any Collateral; (F) to settle, compromise or adjust any suit, action or proceeding described in clause (E) above and, in connection therewith, to give such discharges or releases as the Lender may deem appropriate; (G) to assign any Patent or Trademark (along with the

goodwill of the business to which any such Trademark pertains), throughout the world for such term or terms, on such conditions, and in such manner, as the Lender shall in its sole discretion determine; and (H) subject to the terms of Section 19, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral as fully and completely as though the Lender were the absolute owner thereof for all purposes, and to do, at the Lender’s option and the Debtors’ expense, at any time, or from time to time, all acts and things which the Lender deems necessary to protect, preserve or realize upon the Collateral and the Lender’s Liens thereon and to effect the intent of this Agreement, all as fully and effectively as the Debtors might do; and

(iv) execute in its own name or on behalf of the Debtors such UCC financing Statements forms and similar instruments as the Lender may from time to time deem reasonably necessary or desirable to protect the security interests of the Lender and any other holders of the Obligations.

The Debtors hereby ratify all that said attorneys shall lawfully do or cause to be done by virtue hereof. This power of attorney is a power coupled with an interest and shall be irrevocable.

(b) Other Powers. The Debtors also authorize the Lender, and any other holders of the Obligations, at any time and from time to time, to execute, in connection with the sale provided for in Section 8 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral.

(c) No Duty on the Lender’s Part. The powers conferred on the Lender hereunder are solely to protect the Lender’s interests in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. The Lender shall be accountable only for amounts that Lender actually receives as a result of the exercise of such powers, and neither they nor any of their officers, directors, employees or agents shall be responsible to the Debtors for any act or failure to act hereunder, except for their own gross negligence or willful misconduct.

7. Performance by the Lender of Debtors’ Obligations. If any of the Debtors fails to perform or comply with any of its agreements contained herein and the Lender, as provided for by the terms of this Agreement, shall itself perform or comply, or otherwise cause performance or compliance, with such agreement, the expenses of the Lender incurred in connection with such performance or compliance shall be payable by the Debtors to the Lender on demand and shall constitute Obligations secured hereby, and if not promptly repaid to the Lender shall bear interest thereon at a rate per annum equal to the Default Rate (as defined in the Notes).

8. Remedies.

(a) If an Event of Default shall occur and be continuing and all applicable notice and cure periods shall have expired, the Lender may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Obligations, all rights and remedies of a secured party under the Code. Without limiting the generality of the foregoing, the Lender, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon the Debtors or any other Person (all and

each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon the Collateral, or any part thereof, and/or may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver the Collateral or any part thereof (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Lender shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption in the Debtors, which right or equity is hereby waived or released. The Debtors further agree, at the Lender’s request, to assemble the Collateral and make it available to the Lender at places which the Lender shall reasonably select, whether at the Debtors’ premises or elsewhere. The Lender shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable costs and expenses of every kind incurred therein or incidental to the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of the Lender hereunder, including, without limitation, reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Obligations, in such order as the Lender may elect, and only after such application and after the payment by the Lender of any other amount required by any provision of law, including, without limitation, Section 9615 of the Code, need the Lender account for the surplus, if any, to the Debtors. To the extent permitted by applicable law, each of the Debtors waives all claims, damages and demands it may acquire against the Lender arising out of the exercise by it of any rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition. The Debtors shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations and the fees and disbursements of any attorneys employed by the Lender to collect such deficiency.

(b) The Debtors agree, upon the occurrence and during the continuation of an Event of Default, to take any actions that the Lender may request in order to enable the Lender to obtain and enjoy the full rights and benefits granted to the Lender under this Agreement and any other Transaction Documents. Without limiting the generality of the foregoing, the Debtors shall upon the occurrence and during the continuation of an Event of Default, at the Debtors’ sole cost and expense, assist in obtaining all approvals which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the Uniform Commercial Code as in effect in any applicable jurisdiction.

9. Limitation on Duties Regarding Preservation of Collateral. The Lender’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession, under Section 9207 of the Code or otherwise, shall be to deal with it in the same manner as the Lender deals with similar property for its own account. No holder of any Obligation, nor any of their respective directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of the Debtors or otherwise.

10. Powers Coupled with an Interest. All authorizations and agencies herein contained with respect to the Collateral are irrevocable and powers coupled with an interest.

11. Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12. Paragraph Headings. The paragraph headings used in this Agreement are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

13. No Waiver; Cumulative Remedies. No holder of any Obligation shall by any act (except by a written instrument pursuant to Section 14 hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default or in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising, on the part of the any holder of the Obligations, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by any holder of any Obligations of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which such holder would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

14. Waivers and Amendments; Parties Bound; Governing Law. None of the terms or provisions of this Agreement may be waived, amended, supplemented or otherwise modified except by a written instrument executed by the Debtors and the Lender; provided that any provision of this Agreement may be waived by the Lender in a written letter or agreement executed by the Lender or by telex or facsimile transmission from the Lender. This Agreement shall be the joint and several obligation of the Debtors; each of the Debtors shall have made all of the representations, warranties, covenants and agreements contained herein. This Agreement shall be binding upon the respective successors and permitted assigns of the Debtors and shall inure to the benefit of the Lender and its successors and assigns. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE SUBSTANTIVE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA.

15. Notices. All notices hereunder to the Debtors or the Lender to be effective shall be in writing (including by telecopy), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered or sent in the manner and to the respective addresses as provided in Section 9.7 of the Purchase Agreement.

Agreement, the Uniform Commercial Code as in effect in any applicable jurisdiction, or other applicable law. The parties further acknowledge and agree that, in the event of any change in law or governmental policy occurring subsequent to the date hereof that affects in any manner the Lender’s rights of access to, or use or sale of, the Collateral, or the procedures necessary to enable the Lender to obtain such rights of access, use or sale, the Lender and the Debtors shall amend this Agreement in such manner as the Lender shall request, in order to provide to the Lender such rights to the greatest extent possible consistent with all Laws and governmental policy.

19. Release. This Agreement and related instruments delivered to the Lender hereunder shall be released by the Lender upon the date on which the Obligations are paid in full and the Credit Facility is terminated.

1. DEFINITIONS. As used in this Agreement, the following terms shall have the following meanings:

(a) “Investors” means Lenfest and any transferees or assignees who agree to become bound by the provisions of this Agreement in accordance with Section 9 hereof.

(b) “register,” “registered,” and “registration” refer to a registration effected by preparing and filing a Registration Statement or Registration Statements in compliance with the Securities Act and pursuant to Rule 415 under the Securities Act or any successor rule providing for offering securities on a continuous basis (“Rule 415”), and the declaration or

ordering of effectiveness of such Registration Statement by the United States Securities and Exchange Commission (the “SEC”).

(c) “Registrable Securities” means (i) the Common Stock issuable upon conversion of the Subordinated Notes, the Series B Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and/or the Series E Preferred Stock, as the case may be (collectively, the “Preferred Stock”); (ii) any Common Stock issued or issuable upon exercise of the 2003 Warrants and/or the 2009 Warrants; and (iii) any Common Stock, or any Common Stock issued or issuable (directly or indirectly) upon conversion and/or exercise of any other securities of the Company, acquired by the Investors after the date hereof.

(d) “Registration Statement” means a registration statement of the Company under the Securities Act.

2. REGISTRATION.

(a) Demand Registration. Upon receipt of a written request (a “Demand Request”) from Investors holding a majority of the Registrable Securities, which Demand Request shall set forth the number of Registrable Securities the Investors are seeking to have registered, the Company shall prepare and file with the SEC as soon as practicable, but in no event later than sixty (60) days from the date of its receipt of a Demand Request, a Registration Statement on Form S-3 (or, if Form S-3 is not then available, on such form of Registration Statement as is then available to effect a registration of all of the Registrable Securities) covering the resale of the Registrable Securities which are the subject of the Demand Request. The Registration Statement filed hereunder, to the extent allowable under the Securities Act and the rules promulgated thereunder (including Rule 416), shall state that such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may become issuable to prevent dilution resulting from stock splits, stock dividends or similar transactions. The Investors shall not be entitled to make more than six (6) Demand Requests pursuant to this Agreement; provided, however, the Investors shall not be entitled to make more than two (2) Demand Requests during any twelve (12) month period. A registration request pursuant to this Section 2(a) shall not be deemed to have been effected and shall not be considered a demand registration which may be requested pursuant to this Section 2(a) unless a registration statement filed pursuant to this Section 2(a) has been declared effective by the SEC.

(b) Piggy-Back Registrations. If at any time prior to the expiration of the Registration Period (as hereinafter defined), the Company shall file with the SEC a Registration Statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities (other than the amendment of a registration statement now on file, registration statements on Form S-4 or Form S-8 or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans), the Company shall send to each Investor written notice of such filing and, if within fifteen (15) days after the receipt of such notice, an Investor shall so request in writing, the Company shall include in such Registration Statement all or any part of the Registrable Securities such Investor requests to be registered, except that if, in connection with any underwritten public offering, the

managing underwriter(s) thereof shall impose a limitation on the number of shares of Common Stock which may be included in the Registration Statement because, in such underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then the Company shall be obligated to include in such Registration Statement only such limited portion of the Registrable Securities with respect to which such Investor has requested inclusion hereunder as the underwriter shall permit. Any exclusion of Registrable Securities shall be made pro rata among the Investors seeking to include Registrable Securities, in proportion to the number of Registrable Securities sought to be included by such Investors; provided, however, that the Company shall not exclude any Registrable Securities unless the Company has first excluded all outstanding securities, the holders of which are not contractually entitled to inclusion of such securities in such Registration Statement or are not contractually entitled to pro rata inclusion with the Registrable Securities; and provided, further, however, that, after giving effect to the immediately preceding proviso, any exclusion of Registrable Securities shall be made pro rata with holders of other securities having the contractual right to include such securities in the Registration Statement other than holders of securities contractually entitled to inclusion of their securities in such Registration Statement by reason of demand registration rights. If an offering in connection with which an Investor is entitled to registration under this Section 2(b) is an underwritten offering, then each Investor whose Registrable Securities are included in such Registration Statement shall offer and sell such Registrable Securities in an underwritten offering using the same underwriter or underwriters and, subject to the provisions of this Agreement, on the same terms and conditions as other shares of Common Stock included in such underwritten offering.

(c) Registrations on Form S-3. Upon receipt of a written request (an “S-3 Request”) from Investors holding a majority of the Registrable Securities, which S-3 Request shall set forth the number of Registrable Securities the Investors are seeking to have registered, if the Company is eligible at the time of such request to use Form S-3, the Company shall prepare and file with the SEC as soon as practicable, but in no event later than sixty (60) days from the date of its receipt of an S-3 Request, a Registration Statement on Form S-3 covering the resale of the Registrable Securities which are the subject of the S-3 Request. The Registration Statement filed hereunder, to the extent allowable under the Securities Act and the rules promulgated thereunder (including Rule 416), shall state that such Registration Statement also covers such indeterminate number of additional shares of Common Stock as may become issuable to prevent dilution resulting from stock splits, stock dividends or similar transactions. The Investors shall not be entitled to make more than two (2) S-3 Requests during any twelve (12) month period.

3. OBLIGATIONS OF THE COMPANY.

In connection with the registration of the Registrable Securities, the Company shall have the following obligations:

(a) The Company shall prepare and file with the SEC the Registration Statement in accordance with Section 2, and cause such Registration Statement relating to Registrable Securities to become effective as soon as practicable after such filing, and keep such Registration Statement effective pursuant to Rule 415 at all times until such date as is the earlier of (i) the date on which all of the Registrable Securities have been sold and (ii) the date on which

all of the Registrable Securities (in the opinion of counsel to the Investors, which shall be sought upon the request of the Company) may be immediately sold to the public without registration or restriction pursuant to Rule 144(k) under the Securities Act or any successor provision (the “Registration Period”), which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein and all documents incorporated by reference therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading, and (iii) shall comply in all material respects with the requirements of the Securities Act and the rules and regulations of the SEC promulgated thereunder. The financial statements of the Company included in the Registration Statement or incorporated by reference therein will comply in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC applicable with respect thereto. Such financial statements will be prepared in accordance with U.S. generally accepted accounting principles, consistently applied, during the periods involved (except in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed on summary statements) and fairly present in all material respects the consolidated financial position of the Company and its consolidated subsidiaries as of the dates thereof and the consolidated results of their operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to immaterial year-end adjustments).

(b) The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to keep the Registration Statement effective at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until the earlier of (i) such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statement or (ii) the expiration of the Registration Period.

(c) The Company shall furnish to each Investor whose Registrable Securities are included in the Registration Statement and its legal counsel (i) promptly after the same is prepared and publicly distributed, filed with the SEC, or received by the Company, one copy of the Registration Statement and any amendment thereto, each preliminary prospectus and prospectus and each amendment or supplement thereto, and, in the case of the Registration Statement referred to in Section 2(a), each letter written by or on behalf of the Company to the SEC or the staff of the SEC (including, without limitation, any request to accelerate the effectiveness of the Registration Statement or amendment thereto), and each item of correspondence from the SEC or the staff of the SEC, in each case relating to the Registration Statement (other than any portion, if any, thereof which contains information for which the Company has sought confidential treatment), (ii) on the date of effectiveness of the Registration Statement or any amendment thereto, a notice stating that the Registration Statement or amendment has been declared effective, and (iii) such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents as such Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor.

(d) The Company shall (i) register and qualify the Registrable Securities covered by the Registration Statement under such other securities or “blue sky” laws of such jurisdictions in the United States as each Investor who holds Registrable Securities being offered reasonably requests, (ii) prepare and file in those jurisdictions such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (A) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (B) subject itself to general taxation in any such jurisdiction, (C) file a general consent to service of process in any such jurisdiction, (D) provide any undertakings that cause the Company undue expense or burden, or (E) make any change in its charter or bylaws, which in each case the Board of Directors of the Company determines to be contrary to the best interests of the Company and its shareholders.

(e) As promptly as practicable after becoming aware of such event, the Company shall notify each Investor of the happening of any event, of which the Company has knowledge, as a result of which the prospectus included in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and, promptly prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to each Investor as such Investor may reasonably request.

(f) The Company shall use reasonable best efforts (i) to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement, and, if such an order is issued, to obtain the withdrawal of such order at the earliest practicable moment (including in each case by amending or supplementing such Registration Statement) and (ii) to notify each Investor who holds Registrable Securities being sold (or, in the event of an underwritten offering, the managing underwriters) of the issuance of such order and the resolution thereof (and if such Registration Statement is supplemented or amended, deliver such number of copies of such supplement or amendment to each Investor as such Investor may reasonably request).

(g) The Company shall permit a single firm of counsel designated by the Investors to review the Registration Statement and all amendments and supplements thereto a reasonable period of time prior to its filing with the SEC, and not file any document in a form to which such counsel reasonably objects.

(h) At the request of an Investor in the case of an underwritten public offering, the Company shall furnish, on the date of effectiveness of the Registration Statement (i) an opinion, dated as of such date, from counsel representing the Company addressed to each Investor and in form, scope and substance as is customarily given in an underwritten public offering and (ii) a letter, dated such date, from the Company’s independent certified public

accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and each Investor.

(i) The Company shall hold in confidence and not make any disclosure of information concerning an Investor provided to the Company unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, (iv) such information has been made generally available to the public other than by the Company or disclosure in violation of this or any other agreement, or (v) such Investor consents to the form and content of any such disclosure. The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to such Investor prior to making such disclosure, and allow the Investor, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information.

(j) The Company shall, prior to the declaration of effectiveness of any registration statement covering Registrable Securities, cause all of the Registrable Securities covered by the Registration Statement to be listed, at its option, on any national securities exchange on which securities of the same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange.

(k) The Company shall provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities.

(l) The Company shall cooperate with the Investors who hold Registrable Securities being offered and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to the Registration Statement and enable such certificates to be in such denominations or amounts, as the case may be, as the managing underwriter or underwriters, if any, or the Investors may reasonably request and registered in such names as the managing underwriter or underwriters, if any, or the Investors may request, and, within five (5) business days after the Registration Statement which includes Registrable Securities is ordered effective by the SEC, the Company shall deliver, and shall cause legal counsel selected by the Company to deliver, to the transfer agent for the Registrable Securities (with copies to the Investors whose Registrable Securities are included in such Registration Statement), an opinion of such counsel in the form reasonably satisfactory to the transfer agent.

4. OBLIGATIONS OF THE INVESTOR.

In connection with the registration of the Registrable Securities, each Investor shall have the following obligations:

(a) It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of a particular Investor that such Investor shall furnish to the Company such information regarding himself or itself, the Registrable Securities held by him or it and the intended method of disposition of the Registrable Securities held by him or it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. At least ten (10) days prior to the anticipated filing date of the Registration Statement, the Company shall notify each Investor of the information the Company requires from each such Investor.

(b) Each Investor, by such Investor’s acceptance of the Registrable Securities, agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of the Registration Statement hereunder. The Company shall not be required to include in any Registration Statement the Registrable Securities of any Investor who fails to cooperate with the Company as reasonably requested in connection with the preparation and filing of the Registration Statement.

(c) Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3(e) or 3(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Investor’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(e) or 3(f) and, if so directed by the Company, such Investor shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction at the Company’s request) all copies in such Investor’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

(d) No Investor may participate in any underwritten distribution hereunder unless such Investor (i) agrees to sell such Investor’s Registrable Securities on the basis provided in any underwriting arrangements in usual and customary form entered into by the Company, (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under underwritten offerings for selling shareholders, (iii) agrees to pay its pro rata share of all underwriting discounts and commissions and any expenses in excess of those payable by the Company pursuant to Section 5 below, and (iv) complies with all applicable laws in connection therewith.

(e) In the event that in the judgment of the Company, it is advisable to suspend the use of a prospectus included in the Registration Statement due to pending material developments or other events which have not yet been publicly disclosed and as to which the Company believes public disclosure would be detrimental to the Company, the Company shall notify each Investor to such effect, and, upon receipt of such notice, each Investor shall immediately discontinue any sales of Registrable Securities pursuant to the Registration Statement until such Investor receives copies of a supplemental or amended prospectus or until such Investor is advised in writing by the Company that the then current prospectus may be used and have received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus (a “Disclosure Delay Period”).

Notwithstanding the foregoing, there shall not be more than an aggregate of ninety (90) days in any twelve (12) month period during which the Company is in a Disclosure Delay Period.

5. EXPENSES OF REGISTRATION. All reasonable expenses incurred by the Company or the Investors in connection with registrations, filings or qualifications pursuant to Sections 2 and 3 above, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, and the reasonable fees and disbursements of counsel for the Investors shall be borne by the Company.

6. INDEMNIFICATION. In the event any Registrable Securities are included in a Registration Statement under this Agreement:

(a) To the extent permitted by law, the Company will indemnify, hold harmless and defend (i) each Investor who holds such Registrable Securities, and (ii) the directors, officers, partners, members, employees and agents of such Investor and each person who controls any Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), if any, (each, an “Indemnified Person”), against any joint or several losses, claims, damages, liabilities or expenses (collectively, together with actions, proceedings or inquiries by any regulatory or self-regulatory organization, whether commenced or threatened, in respect thereof, “Claims”) to which any of them may become subject insofar as such Claims arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in a Registration Statement or the omission or alleged omission to state therein a material fact required to be stated or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities (the matters in the foregoing clauses (i) through (iii) being, collectively, “Violations”). The Company shall reimburse the Investors and each other Indemnified Person, promptly as such expenses are incurred and are due and payable, for any reasonable legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a) shall not apply to a Claim arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person for use in the Registration Statement or any such amendment thereof or supplement thereto. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by any Investor pursuant to Section 9 hereof.

(b) In connection with any Registration Statement in which an Investor is participating, each such Investor agrees severally and not jointly to indemnify, hold harmless and

defend, to the same extent and in the same manner set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement, its employees, agents and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any other shareholder selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such shareholder within the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an “Indemnified Party”), against any Claim to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and, subject to Section 6(c), such Investor will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld; provided, further, however, that the Investor shall be liable in the aggregate to all Indemnified Parties under this Agreement (including this Section 6(b) and Section 7) for only that amount as does not exceed the net proceeds actually received by such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented.

(c) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that such indemnifying party shall not be entitled to assume such defense and an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential conflicts of interest between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding or the actual or potential defendants in, or targets of, any such action include both the Indemnified Person or the Indemnified Party and the indemnifying party and any such Indemnified Person or Indemnified Party reasonably determines that there may be legal defenses available to such Indemnified Person or Indemnified Party which are in conflict with those available to such indemnifying party. The indemnifying party shall pay for only one separate legal counsel for the

Indemnified Person or the Indemnified Parties, as applicable, and such legal counsel shall be selected by Investors holding a majority-in-interest of the Registrable Securities included in the Registration Statement to which the Claim relates (with the approval of the initial Investor if it holds Registrable Securities included in such Registration Statement), if the Investors are entitled to indemnification hereunder, or by the Company, if the Company is entitled to indemnification hereunder, as applicable. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is actually prejudiced in its ability to defend such action. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable.

7. CONTRIBUTION. To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the Indemnified Person or Indemnified Party, as the case may be, on the other hand, with respect to the Violation giving rise to the applicable Claim; provided, however, that (i) no contribution shall be made under circumstances where the party would not have been liable for indemnification under the fault standards set forth in Section 6, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation, and (iii) contribution (together with any indemnification or other obligations under this Agreement) by any seller of Registrable Securities shall be limited in the aggregate amount to the net amount of proceeds actually received by such seller from the sale of such Registrable Securities.

8. REPORTS UNDER THE EXCHANGE ACT.

EXHIBIT G
FORM OF GUARANTY AGREEMENT

GUARANTY

THIS GUARANTY (this “Guaranty”), dated as of April 24, 2009, is made by ENTERTAINMENT TECHNOLOGY CORPORATION, a Pennsylvania corporation, and each other subsidiary of the Borrower (as hereinafter defined) that at any time hereafter is formed, created or acquired, or has any assets or operations if formed prior to the date hereof, and their respective successors and permitted assigns (collectively, the “Guarantors”), in favor of H.F. LENFEST (the “Lender”).

WITNESSETH

WHEREAS, Environmental Tectonics Corporation (the “Borrower”) and the Lender are parties to a Secured Credit Facility and Warrant Purchase Agreement, dated as of the date hereof (as amended, supplemented or otherwise modified from time to time, the “Purchase Agreement”);

WHEREAS, the Purchase Agreement provides that, as a condition precedent to the making of one or more advances thereunder by the Lender to the Borrower (the “Credit Facility”), the Guarantors must execute a guaranty in favor of the Lender;

WHEREAS, the Guarantors will derive substantial benefits from the Purchase Agreement and the Credit Facility; and

WHEREAS, the rights granted to the Lender herein shall be subject to the terms and conditions of the Subordination Agreement (as defined in the Purchase Agreement).

NOW, THEREFORE, in consideration of the premises and to induce the Lender to provide the Credit Facility, the Guarantors, intending to be legally bound, hereby agree with the Lender as follows:

1. Defined Terms. Capitalized terms which are not defined herein have the meaning given to such terms in the Purchase Agreement. As used herein, “Obligations” shall mean the unpaid principal of (which such term shall include any payments of principal the Lender is compelled to surrender or disgorge) and interest on (including, without limitation, interest accruing after the maturity of the Credit Facility and interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to the Borrower, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) the Credit Facility, and all other obligations and liabilities of the Borrower to the Lender whether direct or indirect, absolute or contingent, liquidated or unliquidated, due or to become due, or now existing or hereafter incurred, which may arise under, out of, or in connection with, the Purchase Agreement, the Notes, the other Transaction Documents and any other document made, delivered or given in connection therewith or herewith, whether on account of principal, interest, reimbursement obligations, fees, indemnities, costs, expenses (including, without limitation, all fees and disbursements of

counsel to the Lender that are required to be paid by the Borrower pursuant to the terms of the Purchase Agreement or any other Transaction Document) or otherwise.

2. Guaranty. This is a Guaranty of payment and not of collectability. The Guarantors hereby jointly and severally, unconditionally and irrevocably guarantee to the Lender, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Obligations. The Guarantors further agree to pay any and all reasonable expenses (including, without limitation, all reasonable fees and disbursements of counsel), which may be paid or incurred by the Lender in enforcing, or obtaining advice of counsel in respect of, any of its rights under this Guaranty. This Guaranty shall remain in full force and effect until the Obligations are paid in full and the Credit Facility is terminated, notwithstanding that from time to time prior thereto the Borrower may be free from any Obligations.

The Guarantors agree that whenever, at any time or from time to time, either shall make any payment to the Lender on account of its liability hereunder, it will notify the Lender in writing that such payment is made under this Guaranty for such purpose. No payment or payments made by the Borrower or any other Person or received or collected by the Lender from the Borrower or any other Person by virtue of any action or proceeding or any set-off or appropriation or application, at any time or from time to time, in reduction of or in payment of the Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the Guarantors hereunder which liability shall, notwithstanding any such payment or payments, remain in full force and effect until the Obligations are paid in full and the Credit Facility is terminated.

3. Right of Set-off. Upon the occurrence and during the continuance of any Event of Default, the Lender is hereby irrevocably authorized at any time and from time to time, without notice to the Guarantors, any such notice being hereby waived by the Guarantors, to set off and appropriate and apply any and all deposits (general or special, time or demand, provisional or final), and any other credits, indebtedness or claims, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by the Lender to or for the credit or the account of the Guarantors, in such amounts as the Lender may elect, on account of the liabilities of the Guarantors hereunder and claims of every nature and description of the Lender against the Guarantors, whether arising hereunder, under the Purchase Agreement, the Notes, or otherwise, as the Lender may elect, whether or not the Lender has made any demand for payment and although such liabilities and claims may be contingent or unmatured. The Lender shall notify the Guarantors promptly of any such set-off made by it and the application made by it of the proceeds thereof, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Lender under this Section 3 are in addition to other rights and remedies (including, without limitation, other rights of set-off), which the Lender may have.

4. No Subrogation. Notwithstanding any payment or payments made by the Guarantors hereunder, or any set-off or application of funds of the Guarantors by the Lender, the Guarantors shall not be entitled to be subrogated to any of the rights of the Lender against the Borrower or against any collateral security or guaranty or right of offset held by the Lender for the payment of the Obligations, nor shall the Guarantors seek any reimbursement or indemnification from the Borrower in respect of payments made by the Guarantors

hereunder, until all amounts owing to the Lender by the Borrower on account of the Obligations are paid in full and the Credit Facility is terminated. If any amount shall be paid to the Guarantors on account of such subrogation or other rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by the Guarantors in trust for the Lender segregated from other assets of the Guarantors, and shall forthwith upon receipt by the Guarantors, be turned over to the Lender in the exact form received by the Guarantors (duly indorsed by the Guarantors to the Lender, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Lender may determine.

5. No Marshalling. Lender has no obligation to marshal any assets in favor of either Guarantor, or against or in payment of (i) the Notes, or (ii) any other obligation owed to Lender by Borrower or either Guarantor.

6. Waivers; Amendments, etc. with respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation of rights against each Guarantor, and without notice to or further assent by each Guarantor, any demand for payment of any of the Obligations made by the Lender may be rescinded by the Lender, and any of the Obligations continued, and the Obligations, the liability of any other party upon or for any part thereof, or any collateral security or guaranty therefor or right of offset with respect thereto may from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Lender, and the Purchase Agreement, the Notes, the other Transaction Documents and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Lender may deem advisable from time to time, and any collateral security, guaranty or right of offset at any time held by the Lender for the payment of the Obligations may, be sold, exchanged, waived, surrendered or released. The Lender shall not have any obligation to protect, secure, perfect or insure any lien at any time held by it as security for the Obligations or for this Guaranty or any property subject thereto.

7. Guaranty Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Lender upon this Guaranty or acceptance of this Guaranty; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this Guaranty; and all dealings between the Borrower or the Guarantors, on the one hand, and the Lender, on the other, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guaranty, waives notice of acceptance of this Guaranty, notice of extensions of credit to the Borrower from time to time, notice of default, diligence, presentment, notice of dishonor, protest and demand for payment. This Guaranty is and shall be construed as a continuing, absolute and unconditional Guaranty of payment without regard to (a) the validity or enforceability of the Purchase Agreement, the Notes, any of the other Transaction Documents, any of the Obligations or any collateral security therefor or guaranty or right of offset with respect thereto at any time or from time to time held by or for the benefit of the Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Borrower against the Lender, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Borrower or the Guarantors) which constitutes, or

might be construed to constitute, an equitable or legal discharge of the Borrower for the Obligations, or of the Guarantors under this Guaranty, in bankruptcy or in any other instance. This Guaranty is intended to be a surety of each Guarantor on behalf of Lender. When the Lender is pursuing its rights and remedies hereunder against the Guarantors, the Lender may, but shall be under no obligation to, pursue such rights and remedies as it may have against the Borrower or any other Person or against any collateral security or guaranty for the Obligations or any right of offset with respect thereto, and any failure by the Lender to pursue such other rights or remedies or to collect any payments from the Borrower or any such other Person or to realize upon such collateral security or guaranty or to exercise any such right of offset, or any release of the Borrower or any such other Person or of any such collateral security, Guaranty or right of offset, shall not relieve the Guarantors of any joint and several liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Lender against the Guarantors.

8. Reinstatement. This Guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for the Borrower or any substantial part of its property, or for any other reason, all as though such payments had not been made.

9. Payments. Each Guarantor hereby agrees that the Obligations will be paid to the order of the Lender without set-off or counterclaim in United States dollars in immediately available funds at the office of the Lender set forth in Section 14 hereof.

10. POWER TO CONFESS JUDGMENT. THIS SECTION 10 SETS FORTH A WARRANT OF AUTHORITY FOR ANY ATTORNEY TO CONFESS JUDGMENT AGAINST THE UNDERSIGNED GUARANTORS.

EACH GUARANTOR HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY OF RECORD, OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF PENNSYLVANIA OR ELSEWHERE, TO APPEAR FOR SUCH GUARANTOR AT ANY TIME OR TIMES, AFTER THE OCCURRENCE OF AN EVENT OF DEFAULT HEREUNDER, IN ANY SUCH COURT IN ANY ACTION BROUGHT AGAINST SUCH GUARANTOR BY THE LENDER WITH RESPECT TO THE AGGREGATE AMOUNTS PAYABLE HEREUNDER, WITH OR WITHOUT DECLARATION FILED, AS OF ANY TERM,

11. Severability. Any provision of this Guaranty which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12. Paragraph Headings. The paragraph headings used in this Guaranty are for convenience of reference only and are not to affect the construction hereof or be taken into consideration in the interpretation hereof.

13. No Waiver; Cumulative Remedies.

No failure to exercise, nor any delay in exercising, on the part of the Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Lender of any right or remedy

hereunder on anyone occasion shall not be construed as a bar to any right or remedy which the Lender would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

14. Waivers and Amendments: Successors and Assigns; Governing Law.

(c) All rents, issues and profits arising or issuing from the Land and the Improvements (the “Rents”) including the Rents arising or issuing from all leases and subleases now or hereafter entered into covering all or any part of the Land and Improvements (the “Leases”), all of which Leases and Rents are hereby assigned to Mortgagee by Mortgagor. The foregoing assignment shall include all cash or securities deposited under Leases to secure performance of lessees of their obligations thereunder, whether such cash or securities are to be held until the expiration of the terms of such leases or applied to one or more installments of rent coming due prior to the expiration of such terms. The foregoing assignment extends to Rents arising both before and after the commencement by or against Mortgagor of any case or proceeding under any Federal or State bankruptcy, insolvency or similar law, and is intended as an absolute assignment and not merely the granting of a security interest. Mortgagor, however, shall have a license to collect, retain and use the Rents so long as no Event of Default shall have occurred and be continuing or shall exist. Mortgagor will execute and deliver to Mortgagee, on demand, such additional assignments and instruments as Mortgagee may require to implement, confirm, maintain and continue the assignment of Rents hereunder;

(d) All proceeds of the conversion, voluntary or involuntary, of any of the foregoing into cash or liquidated claims;

(e) And without limiting any of the other provisions of this Mortgage, Mortgagor, as debtor, expressly grants unto Mortgagee, as secured party, a security interest in all those portions of the Property which may be subject to the Uniform Commercial Code provisions applicable to secured transactions under the laws of the state in which the Property is located (the “UCC”), and Mortgagor will execute and deliver to Mortgagee on demand such financing statements and other instruments as Mortgagee may require in order to perfect and maintain such security interest under the UCC on the aforesaid collateral.

To have and to hold the same unto Mortgagee, its successors and assigns, forever, under and subject to the terms of the Senior Credit Agreement and related documents (collectively, the “Senior Credit Documents”). All of the duties and obligations of Mortgagor and the rights and remedies of Mortgagee hereunder are under and subject in all respects to performance of the duties and obligations of Mortgagor to Senior Lender and to the rights and remedies of Senior Lender under the Senior Credit Documents. The failure by Mortgagor to perform or comply with any of the provisions of this Mortgage shall not be an Event of Default hereunder if such failure arises solely from Mortgagor’s performance or compliance with comparable obligations under the Senior Credit Documents and performance or compliance with both the Senior Credit Documents and this Mortgage is impossible.

Provided, however, that if Mortgagor shall pay to Mortgagee the Obligations, and if Mortgagor shall keep and perform each of its other covenants, conditions and agreements set forth herein and in the other Loan Documents, then, upon the termination of all obligations, duties and commitments of Mortgagor under the Obligations and this Mortgage, and subject to the provisions of the paragraph entitled “Survival; Successors and Assigns”, the estate hereby granted and conveyed shall become null and void.

This Mortgage is an “Open-End Mortgage” as set forth in 42 Pa. C.S.A. §8143 and secures obligations up to a maximum principal amount of Thirty-Seven Million Five Hundred

Thousand Dollars ($37,500,000), plus accrued and unpaid interest outstanding at any time under the Loan Documents, including advances for the payment of taxes and municipal assessments, maintenance charges, insurance premiums, costs incurred for the protection of the Property or the lien of this Mortgage, expenses incurred by Mortgagee by reason of default by Mortgagor under this Mortgage and advances for construction, alteration or renovation on the Property or for any other purpose, together with all other sums due hereunder or secured hereby. All notices to be given to Mortgagee pursuant to 42 Pa. C.S.A. §8143 shall be given as set forth in Section 18.

1. Representations and Warranties. Mortgagor represents and warrants to Mortgagee that Mortgagor has good and marketable title to an estate in fee simple absolute in the Land and Improvements and has all right, title and interest in all other property constituting a part of the Property, in each case free and clear of all liens and encumbrances, except as may otherwise be set forth on an Exhibit B hereto. This Mortgage is a valid and enforceable lien on the Property (except as set forth on Exhibit B). Mortgagor shall preserve such title as it warrants herein and the validity and priority of the lien hereof and shall forever warrant and defend the same to Mortgagee against the claims of all persons claiming by, through or under Mortgagor.

2. Affirmative Covenants. Until all of the Obligations shall have been fully paid, satisfied and discharged Mortgagor shall:

(a) Payment and Performance of Obligations. Pay or cause to be paid and perform all Obligations when due as provided in the Loan Documents.

(b) Legal Requirements. Promptly comply with and conform in all material respects to all present and future laws, statutes, codes, ordinances, orders and regulations and all covenants, restrictions and conditions which may be applicable to Mortgagor or to any of the Property (the “Legal Requirements”).

(c) Impositions. Before interest or penalties are due thereon and otherwise when due, Mortgagor shall pay all taxes of every kind and nature, all charges for any easement or agreement maintained for the benefit of any of the Property, all general and special assessments (including any condominium or planned unit development assessments, if any), levies, permits, inspection and license fees, all water and sewer rents and charges, and all other charges and liens, whether of a like or different nature, imposed upon or assessed against Mortgagor or any of the Property (the “Impositions”) unless the amount thereof is being contested in good faith by Mortgagor by appropriate proceedings with adequate reserves made for the payment thereof. Within thirty (30) days after the payment of any Imposition if requested by Mortgagee, Mortgagor shall deliver to Mortgagee evidence acceptable to Mortgagee of such payment. Mortgagor’s obligations to pay the Impositions shall survive Mortgagee’s taking title to the Property through foreclosure, deed-in-lieu or otherwise.

(d) Maintenance of Security. Use, and permit others to use, the Property only for its present use or such other uses as permitted by applicable Legal Requirements and approved in writing by Mortgagee. Mortgagor shall keep the Property in good condition and order and in a rentable and tenantable state of repair and will make or cause to be made, as and when necessary, all repairs, renewals, and replacements, structural and nonstructural, exterior

and interior, foreseen and unforeseen, ordinary and extraordinary, provided, however, that no structural repairs, renewals or replacements in excess of $100,000 shall be made without Mortgagee’s prior written consent, not to be unreasonably withheld, conditioned or delayed. Mortgagor shall not remove, demolish or alter any material portion of the Property or any of the Property in a manner that materially adversely affects the same, nor commit or suffer waste with respect thereto, nor permit the Property to become deserted or abandoned. Mortgagor covenants and agrees not to take or permit any action with respect to the Property which will in any manner materially impair the security of this Mortgage.

3. Leases. Except as permitted by the Loan Documents, Mortgagor shall not (a) execute an assignment or pledge of the Rents or the Leases other than in favor of Mortgagee; (b) accept any prepayment of an installment of any Rents more than 30 days prior to the due date of such installment; or (c) enter into or amend any of the terms of any of the Leases without Mortgagee’s prior written consent, not to be unreasonably withheld, conditioned or delayed. Any or all leases or subleases of all or any part of the Property shall be subject in all respects to Mortgagee’s prior written consent, not to be unreasonably withheld, conditioned or delayed, shall be subordinated to this Mortgage and to Mortgagee’s rights and, together with any and all rents, issues or profits relating thereto, shall be assigned at the time of execution to Mortgagee as additional collateral security for the Obligations, all in such form, substance and detail as is satisfactory to Mortgagee in its reasonable discretion.

4. Due on Sale Clause. Mortgagor shall not sell, convey or otherwise transfer any interest in the Property (whether voluntarily or by operation of law), or agree to do so, without Mortgagee’s prior written consent, including (a) any sale, conveyance, assignment, or other transfer of (including installment land sale contracts), or the grant of a security interest in, all or any part of the legal or equitable title to the Property, except as otherwise permitted hereunder; or (b) any lease of all or any portion of the Property. Any default under this Section shall cause an immediate acceleration of the Obligations without any demand by Mortgagee.

5. Insurance. Mortgagor shall keep the Improvements continuously insured, in an amount not less than the cost to replace the Improvements or an amount not less than eighty percent (80%) of the full insurable value of the Property, whichever is greater, against loss or damage by fire, with extended coverage and against other hazards as Mortgagee may from time to time require. With respect to any property under construction or reconstruction, Mortgagor shall maintain builder’s risk insurance. Mortgagor shall also maintain comprehensive general public liability insurance, in an amount of not less than One Million Dollars ($1,000,000) per occurrence and Two Million Dollars ($2,000,000) general aggregate per location, which includes contractual liability insurance for Mortgagor’s obligations under the Leases, and worker’s compensation insurance. All property and builder’s risk insurance shall include protection for continuation of income for a period of twelve (12) months, in the event of any damage caused by the perils referred to above. All policies, including policies for any amounts carried in excess of the required minimum and policies not specifically required by Mortgagee, shall be with an insurance company or companies satisfactory to Mortgagee, shall be in form satisfactory to Mortgagee, shall meet all coinsurance requirements of Mortgagee, shall be maintained in full force and effect, with premiums satisfied as collateral security for payment of the Obligations, shall be endorsed with a standard mortgagee clause in favor of Mortgagee and shall provide for at least thirty (30) days notice of cancellation to Mortgagee. Such insurance

shall also name Mortgagee as an additional insured under the comprehensive general public liability policy and Mortgagor shall also deliver to Mortgagee a copy of the replacement cost coverage endorsement. If the Property is located in an area which has been identified by any governmental agency, authority or body as a flood hazard area or the like, then Mortgagor shall maintain a flood insurance policy covering the Improvements in an amount not less than the appraised value of the Property or the maximum limit of coverage available under the federal program, whichever amount is less.

6. Rights of Mortgagee to Insurance Proceeds. In the event of loss, Mortgagee shall have the exclusive right to adjust, collect and compromise all Material Insurance Claims (as defined below), and Mortgagor shall not adjust, collect or compromise any Material Insurance Claims under said policies without Mortgagee’s prior written consent, not to be unreasonably withheld, conditioned or delayed. Each insurer is hereby authorized and directed to make payment under said policies, including return of unearned premiums, directly to Mortgagee instead of to Mortgagor and Mortgagee jointly, and Mortgagor appoints Mortgagee as Mortgagor’s attorney-in-fact to endorse any draft therefor. All Material Insurance Claims proceeds may, at Mortgagee’s sole option, be applied to all or any part of the Obligations and in any order (notwithstanding that such Obligations may not then otherwise be due and payable) or to the repair and restoration of any of the Property under such terms and conditions as Mortgagee may reasonably impose; provided, however, that so long as no Event of Default has occurred and is continuing, such proceeds shall be applied to the repair and restoration of the Property. All other insurance claim proceeds must be applied to the repair and restoration of the Property under terms and conditions satisfactory to Mortgagee. For purposes of this paragraph 6, the term “Material Insurance Claim” means any insurance claim in excess of $500,000.

7. Installments for Insurance, Taxes and Other Charges. Upon Mortgagee’s request at any time following the occurrence and during the continuance of an Event of Default, Mortgagor shall pay to Mortgagee monthly, an amount equal to one-twelfth (1/12) of the annual premiums for the insurance policies referred to hereinabove and the annual Impositions and any other item which at any time may be or become a lien upon the Property (the “Escrow Charges”). The amounts so paid shall be used in payment of the Escrow Charges so long as no Event of Default shall have occurred and is continuing. No amount so paid to Mortgagee shall be deemed to be trust funds, nor shall any sums paid bear interest. Mortgagee shall have no obligation to pay any insurance premium or Imposition if at any time the funds being held by Mortgagee for such premium or Imposition are insufficient to make such payments. If, at any time, the funds being held by Mortgagee for any insurance premium or Imposition are exhausted, or if Mortgagee determines, in its reasonable discretion, that such funds will be insufficient to pay in full any insurance premium or Imposition when due, Mortgagor shall promptly pay to Mortgagee, upon demand, an amount which Mortgagee shall estimate as sufficient to make up the deficiency. Upon the occurrence and during the continuance of an Event of Default, Mortgagee shall have the right, at its election, to apply any amount so held against the Obligations due and payable in such order as Mortgagee may deem fit, and Mortgagor hereby grants to Mortgagee a lien upon and security interest in such amounts for such purpose.

8. Condemnation. Mortgagor, immediately upon obtaining knowledge of the institution of any proceedings for the condemnation or taking by eminent domain of any of the Property, shall notify Mortgagee of the pendency of such proceedings. Mortgagee may

participate in any such proceedings and Mortgagor shall deliver to Mortgagee all instruments requested by it to permit such participation. Any award or compensation for property taken or for damage to property not taken in excess of $500,000, whether as a result of such proceedings or in lieu thereof, is hereby assigned to and shall be received and collected directly by Mortgagee, and any award or compensation shall be applied, at Mortgagee’s option, to any part of the Obligations and in any order (notwithstanding that any of such Obligations may not then be due and payable) or to the repair and restoration of any of the Property under such terms and conditions as Mortgagee may reasonably impose provided, however, that so long as no Event of Default has occurred and is continuing, such proceeds shall be applied to the repair and restoration of the Property.

9. Environmental Matters. (a) For purposes of this Section 9, the term “Environmental Laws” shall mean all federal, state and local laws, regulations and orders, whether now or in the future enacted or issued, pertaining to the protection of land, water, air, health, safety or the environment. The term “Regulated Substances” shall mean all substances regulated by Environmental Laws, or which are known or considered to be harmful to the health or safety of persons, or the presence of which may require investigation, notification or remediation under the Environmental Laws. The term “Contamination” shall mean the discharge, release, emission, disposal or escape of any Regulated Substances into the environment other than as permitted under applicable Environmental Laws.

(b) Mortgagor represents and warrants except as provided in the Loan Documents or otherwise disclosed to Lender in writing (i) that no Contamination is present at, on or under the Property and that no Contamination is being or, to the best of Mortgagor’s knowledge, has been emitted onto any surrounding property other than as permitted under applicable Environmental Laws; (ii) all operations and activities on the Property have been and are being conducted in accordance with all Environmental Laws, and Mortgagor has all permits and licenses required under the Environmental Laws; (iii) no underground or aboveground storage tanks are or have been located on or under the Property; and (iv) no legal or administrative proceeding is pending or, to the best of Mortgagor’s knowledge, threatened relating to any environmental condition, operation or activity on the Property regulated under any applicable Environmental Laws, or any violation or alleged violation of Environmental Laws. These representations and warranties shall be true as of the date hereof, and shall be deemed to be continuing representations and warranties which must remain true, correct and accurate during the entire duration of the term of this Mortgage.

(c) Mortgagor shall ensure, at its sole cost and expense, that the Property and the conduct of all operations and activities thereon comply and continue to comply with all Environmental Laws. Mortgagor shall notify Mortgagee promptly and in reasonable detail in the event that Mortgagor becomes aware of any violation of any Environmental Laws, the presence or release of any Contamination with respect to the Property, or any governmental or third party claims under applicable Environmental Laws relating to the environmental condition of the Property or the conduct of operations or activities thereon. Mortgagor also agrees not to permit or allow the presence of Regulated Substances on any part of the Property, except (i) to the extent such Regulated Substances are used without violating any Environmental Laws; and (ii) those Regulated Substances which are naturally occurring on the Property. Mortgagor agrees not to cause, allow or permit the presence of any Contamination on the Property except

to the extent such Contamination is in compliance with all applicable Environmental Laws.

(d) Mortgagee shall not be liable for, and Mortgagor shall indemnify, defend and hold Mortgagee and all of its officers, directors, employees and agents, and all of their respective successors and assigns harmless from and against all losses, costs, liabilities, damages, fines, claims, penalties and expenses (including reasonable attorneys’, consultants’ and contractors’ fees, costs incurred in the investigation, defense and settlement of claims, as well as costs incurred in connection with the investigation, remediation or monitoring of any Regulated Substances or Contamination) that Mortgagee may suffer or incur (including as holder of the Mortgage, as mortgagee in possession or as successor in interest to Mortgagor as owner of the Property by virtue of a foreclosure or acceptance of a deed in lieu of foreclosure) as a result of or in connection with (i) any Environmental Laws (including the assertion that any lien existing or arising pursuant to any Environmental Laws takes priority over the lien of the Mortgage); (ii) the breach in any material respect of any representation, warranty, covenant or undertaking by Mortgagor in this Section 9; (iii) the presence on or the migration of any Contamination or Regulated Substances on, under or through the Property; or (iv) any litigation or claim by the government or by any third party in connection with the environmental condition of the Property or the presence or migration of any Regulated Substances or Contamination on, under, to or from the Property; provided, however, that Mortgagor shall not be liable under this Section (d) for any damages caused by Mortgagee’s gross negligence or willful misconduct.

(e) Upon Mortgagee’s request, Mortgagor shall execute and deliver an Environmental Indemnity Agreement satisfactory in form and substance to Mortgagee, to more fully reflect Mortgagor’s representations, warranties, covenants and indemnities with respect to the Environmental Laws.

10. Inspection of Property. Mortgagee shall have the right to enter the Property upon reasonable prior notice at any reasonable hour for the purpose of inspecting the order, condition and repair of the buildings and improvements erected thereon, as well as the conduct of operations and activities on the Property. Mortgagee may enter the Property (and cause Mortgagee’s employees, agents and consultants to enter the Property), upon reasonable prior written notice to Mortgagor, to conduct any and all environmental testing deemed appropriate by Mortgagee in his reasonable discretion. The environmental testing shall be accomplished by whatever means Mortgagee may deem appropriate, including the taking of soil samples and the installation of ground water monitoring wells or other intrusive environmental tests. Mortgagor shall provide Mortgagee (and Mortgagee’s employees, agents and consultants) reasonable rights of access to the Property as well as such information about the Property and the past or present conduct of operations and activities thereon as Mortgagee shall reasonably request.

11. Events of Default. The occurrence of any one or more of the following events shall constitute an “Event of Default” hereunder: (a) any Event of Default (as defined in the Credit Facility Agreement); (b) the failure by Mortgagor to perform any of its other obligations under this Mortgage or under any Environmental Indemnity Agreement executed and delivered pursuant to Section 9(e) for a period of fifteen (15) days or more after written notice thereof is delivered to Mortgagor; (c) falsity, inaccuracy or material breach by Mortgagor of any written warranty, representation or statement made herein by Mortgagor; (d) any lien against or the

making of any levy, seizure or attachment of or on the Property not dismissed or adequately bonded within ninety (90) days; (e) the failure of Mortgagee to have a mortgage lien on the Property; (f) foreclosure proceedings are instituted against the Property upon any other lien or claim, whether alleged to be superior or junior to the lien of this Mortgage which is not dismissed within ninety (90) days; (g) the failure by Mortgagor to pay any Impositions as required under Section 2(c), or to maintain in full force and effect any insurance required under Section 5; or (h) Mortgagor or any other obligor or guarantor of any of the Obligations, shall at any time deliver or cause to be delivered to Mortgagee a notice pursuant to 42 Pa. C.S.A. §8143 electing to limit the indebtedness secured by this Mortgage.

12. Rights and Remedies of Mortgagee. If an Event of Default occurs, Mortgagee may, at its option and without demand, notice or delay, do one or more of the following:

(a) Mortgagee may declare the entire unpaid principal balance of the Obligations, together with all interest thereon, to be due and payable immediately.

(b) Mortgagee may (i) institute and maintain an action of mortgage foreclosure against the Property and the interests of Mortgagor therein, (ii) institute and maintain an action on any instruments evidencing the Obligations or any portion thereof, and (iii) take such other action at law or in equity for the enforcement of any of the Loan Documents as the law may allow, and in each such action Mortgagee shall be entitled to all costs of suit and attorneys fees.

(c) Mortgagee may, in his sole and absolute discretion: (i) collect any or all of the Rents, including any Rents past due and unpaid, (ii) perform any obligation or exercise any right or remedy of Mortgagor under any Lease, or (iii) enforce any obligation of any tenant of any of the Property. Mortgagee may exercise any right under this subsection (c), whether or not Mortgagee shall have entered into possession of any of the Property, and nothing herein contained shall be construed as constituting Mortgagee a “mortgagee in possession”, unless Mortgagee shall have entered into and shall continue to be in actual possession of the Property. Mortgagor hereby authorizes and directs each and every present and future tenant of any of the Property to pay all Rents directly to Mortgagee and to perform all other obligations of that tenant for the direct benefit of Mortgagee, as if Mortgagee were the landlord under the Lease with that tenant, immediately upon receipt of a demand by Mortgagee to make such payment or perform such obligations. Mortgagor hereby waives any right, claim or demand it may now or hereafter have against any such tenant by reason of such payment of Rents or performance of obligations to Mortgagee, and any such payment or performance to Mortgagee shall discharge the obligations of the tenant to make such payment or performance to Mortgagor.

(d) Mortgagee shall have the right, in connection with the exercise of its remedies hereunder, to the appointment of a receiver to take possession and control of the Property or to collect the Rents, without notice and without regard to the adequacy of the Property to secure the Obligations. A receiver while in possession of the Property shall have the right to make repairs and to make improvements necessary or advisable in its or his opinion to preserve the Property, or to make and keep it rentable to the best advantage, and Mortgagee may advance moneys to a receiver for such purposes. Any moneys so expended or advanced by Mortgagee or by a receiver shall be added to and become a part of the Obligations secured by

this Mortgage.

13. Application of Proceeds. Mortgagee shall apply the proceeds of any foreclosure sale of, or other disposition or realization upon, or Rents or profits from, the Property to satisfy the Obligations in such order of application as Mortgagee shall determine in its exclusive discretion.

14. Confession of Judgment in Ejectment. At any time after the occurrence and during the continuance of an Event of Default, without further notice, regardless of whether Mortgagee has asserted any other right or exercised any other remedy under this Mortgage or any of the other Loan Documents, he shall be lawful for any attorney of any court of record as attorney for Mortgagor to confess judgment in ejectment against Mortgagor and all persons claiming under Mortgagor for the recovery by Mortgagee of possession of all or any part of the Property, for which this Mortgage shall be sufficient warrant. If for any reason after such action shall have commenced the same shall be discontinued and the possession of the Property shall remain in or be restored to Mortgagor, Mortgagee shall have the right upon any subsequent default or defaults to bring one or more amicable action or actions as hereinbefore set forth to recover possession of all or any part of the Property.

15. Mortgagee’s Right to Protect Security. Mortgagee is hereby authorized to do any one or more of the following, irrespective of whether an Event of Default has occurred: (a) appear in and defend any action or proceeding purporting to affect the security hereof or Mortgagee’s rights or powers hereunder if Mortgagor fails to so defend such action or proceeding to the satisfaction of Mortgagee; (b) purchase such insurance policies covering the Property as he may elect if Mortgagor fails to maintain the insurance coverage required hereunder; and (c) take such action as Mortgagee may determine to pay, perform or comply with any Impositions or Legal Requirements, to cure any Events of Default and to protect its security in the Property.

16. Appointment of Mortgagee as Attorney-in-Fact. Mortgagee, or any of his officers, is hereby irrevocably appointed attorney-in-fact for Mortgagor (without requiring any of them to act as such), such appointment being coupled with an interest, to do any or all of the following: (a) collect the Rents after the occurrence and during the continuance of an Event of Default; (b) settle for, collect and receive any awards payable under Section 8 from the authorities making the same; and (c) execute, deliver and file such financing statements and other instruments as Mortgagee may require in order to perfect and maintain his security interest under the Uniform Commercial Code on any portion of the Property.

17. Certain Waivers. Mortgagor hereby waives and releases all benefit that might accrue to Mortgagor by virtue of any present or future law exempting the Property, or any part of the proceeds arising from any sale thereof, from attachment, levy or sale on execution, or providing for any stay of execution, exemption from civil process or extension of time for payment or any rights of marshalling in the event of any sale hereunder of the Property, and, unless specifically required herein, all notices of Mortgagor’s default or of Mortgagee’s election to exercise, or Mortgagee’s actual exercise of any option under this Mortgage or any other Loan Document.

18. Notices. All notices, demands, requests, consents, approvals and other communications required or permitted hereunder must be in writing and will be effective upon receipt by Mortgagor or Mortgagee. Such notices and other communications may be hand-delivered, sent by facsimile transmission with confirmation of delivery and a copy sent by first-class mail, or sent by nationally recognized overnight courier service, to a party’s address set forth above or to such other address as Mortgagor or Mortgagee may give to the other in writing for such purpose.

19. Further Acts. Mortgagor will, at the cost of Mortgagor, and without expense to Mortgagee, do, execute, acknowledge and deliver all further acts, deeds, conveyances, mortgages, assignments, notices of assignment, transfers and assurances as Mortgagee shall, from time to time, reasonably require for the better assuring, conveying, assigning, transferring or confirming unto Mortgagee the property and rights hereby mortgaged, or which Mortgagor may be or may hereafter become bound to convey or assign to Mortgagee, or for carrying out the intent of or facilitating the performance of the terms of this Mortgage or for filing, registering or recording this Mortgage. Mortgagor grants to Mortgagee an irrevocable power of attorney coupled with an interest for the purpose of exercising and perfecting any and all rights and remedies available to Mortgagee under the Note, this Mortgage, the other Loan Documents, at law or in equity, including, without limitation, the rights and remedies described in this paragraph.

20. Changes in the Laws Regarding Taxation. If any law is enacted or adopted or amended after the date of this Mortgage which deducts the Obligations from the value of the Property for the purpose of taxation or which imposes a tax, either directly or indirectly, on Mortgagor or Mortgagee’s interest in the Property, Mortgagor will pay such tax, with interest and penalties thereon, if any. If Mortgagee determines that the payment of such tax or interest and penalties by Mortgagor would be unlawful or taxable to Mortgagee or unenforceable or provide the basis for a defense of usury, then Mortgagee shall have the option, by written notice of not less than one hundred twenty (120) days, to declare the entire Obligations immediately due and payable.

21. Documentary Stamps. If at any time the United States of America, any State thereof or any subdivision of any such State shall require revenue or other stamps to be affixed to the Note or this Mortgage, or impose any other tax or charge on the same, Mortgagor will pay for the same, with interest and penalties thereon, if any.

22. Preservation of Rights. No delay or omission on Mortgagee’s part to exercise any right or power arising hereunder will impair any such right or power or be considered a waiver of any such right or power, nor will Mortgagee’s action or inaction impair any such right or power. Mortgagee’s rights and remedies hereunder are cumulative and not exclusive of any other rights or remedies which Mortgagee may have under other agreements, at law or in equity. Mortgagee may exercise any one or more of its rights and remedies without regard to the adequacy of its security.

23. Illegality. In case any one or more of the provisions contained in this Mortgage should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability

of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

24. Changes in Writing. No modification, amendment or waiver of any provision of this Mortgage nor consent to any departure by Mortgagor therefrom will be effective unless made in a writing signed by Mortgagee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on Mortgagor in any case will entitle Mortgagor to any other or further notice or demand in the same, similar or other circumstance.

25. Entire Agreement. This Mortgage (including the documents and instruments referred to herein) constitutes the entire agreement and supersedes all other prior agreements and understandings, both written and oral, between Mortgagor and Mortgagee with respect to the subject matter hereof.

26. Survival; Successors and Assigns. This Mortgage will be binding upon and inure to the benefit of Mortgagor and Mortgagee and their respective heirs, executors, administrators, successors and assigns; provided, however, that Mortgagor may not assign this Mortgage in whole or in part without Mortgagee’s prior written consent and Mortgagee at any time may assign this Mortgage in whole or in part; and provided, further, that the rights and benefits under the Paragraphs entitled “Environmental Matters”, “Inspection of Property” and “Indemnity” shall also inure to the benefit of any persons or entities who acquire title or ownership of the Property from or through Mortgagee or through action of Mortgagee (including a foreclosure, sheriff’s or judicial sale). The provisions of Paragraphs entitled “Environmental Matters”, “Inspection of Property” and “Indemnity” shall survive the termination, satisfaction or release of this Mortgage, the foreclosure of this Mortgage or the delivery of a deed in lieu of foreclosure.

27. Interpretation. In this Mortgage, the singular includes the plural and the plural the singular; references to statutes are to be construed as including all statutory provisions consolidating, amending or replacing the statute referred to; the word “or” shall be deemed to include “and/or”, the words “including”, “includes” and “include” shall be deemed to be followed by the words “without limitation” and references to sections or exhibits are to those of this Mortgage unless otherwise indicated. Section headings in this Mortgage are included for convenience of reference only and shall not constitute a part of this Mortgage for any other purpose. If this Mortgage is executed by more than one party as Mortgagor, the obligations of such persons or entities will be joint and several.

28. Indemnity. Mortgagor agrees to indemnify each of Mortgagee, his affiliated companies, directors, officers and employees and Mortgagee’s holding company, if any (the “Indemnified Parties”), and to hold each Indemnified Party harmless from and against any and all claims, damages, losses, liabilities and expenses (including all reasonable fees and charges of internal or external counsel with whom any Indemnified Party may consult and all reasonable expenses of litigation or preparation therefor) which any Indemnified Party may incur or which may be asserted against any Indemnified Party in connection with or arising out of the matters referred to in this Mortgage or in the other Loan Documents by any person, entity or governmental authority (including any person or entity claiming derivatively on behalf of

Mortgagor), whether (a) arising from or incurred in connection with any breach of a representation, warranty or covenant by Mortgagor, or (b) arising out of or resulting from any suit, action, claim, proceeding or governmental investigation, pending or threatened, whether based on statute, regulation or order, or tort, or contract or otherwise, before any court or governmental authority, which arises out of or relates to this Mortgage, any other Loan Document, or the use of the proceeds of the Loan; provided, however, that the foregoing indemnity agreement shall not apply to claims, damages, losses, liabilities and expenses attributable to an Indemnified Party’s gross negligence or willful misconduct. The indemnity agreement contained in this Section shall survive the termination of this Mortgage, payment of any Loan and assignment of any rights hereunder. Mortgagor may participate at its expense in the defense of any such action or claim.

SECURITY AGREEMENT

This SECURITY AGREEMENT (this “Agreement”) is made and entered into as of February 18, 2009, by ENVIRONMENTAL TECTONICS CORPORATION (“Debtor”), in favor of H.F. LENFEST (“Secured Party”).

RECITALS

WHEREAS, Debtor has executed a Secured Promissory Note, dated the date hereof, pursuant to which Debtor has borrowed $2,000,000 from Secured Party (the “Note”). The parties intend that Debtor’s obligation to repay the Note be secured by all of the assets of Debtor. Any capitalized terms not otherwise defined herein shall have the meanings set forth in the Note.

In consideration of the purchase of the Note by Secured Party and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, Debtor hereby agrees with Secured Party as follows:

1. Grant of Security Interest. To secure Debtor’s full and timely performance of all of Debtor’s obligations and liabilities to Secured Party pursuant to the Note (including, without limitation, Debtor’s obligation to timely pay the principal amount of, and accrued interest on, the Note), and any amendments, modifications or reissuance of the Note and all other debt owed by Debtor to Secured Party, and all other amounts payable hereunder, including all costs and expenses incurred by Secured Party to enforce Secured Party’s rights hereunder (the “Obligations”), Debtor hereby grants to Secured Party a continuing security interest (the “Security Interest”) in and to all of the property described on Exhibit A to this Agreement (the “Collateral”) and all proceeds and products thereof. Debtor will not grant any other security interests in the Collateral without the written consent of Secured Party.

2. Events of Default. For purposes of this Agreement, “Event of Default” means any of the following:

(b) default by Debtor in punctual performance of any of the non-monetary obligations, covenants, terms or provisions contained or referred to in this Agreement, or the Note secured hereby, each as amended, replaced or modified, if such default shall continue unremedied for a period of ten (10) days following written notice of default by Secured Party to Debtor;

(c) any use of the proceeds of the Note for any purpose other than working capital necessary for the performance of the Government Contract;

(d) any warranty, representation or statement contained in this Agreement or the Note proves to have been false;

(e) loss, theft, substantial damage, destruction, sale (except as authorized in this Agreement) or encumbrance to or of any portion of the Collateral (except such encumbrances and liens which arise in the ordinary course of business and both (A) do not materially impair Debtor’s ownership or use of the Collateral and (B) are junior to and do not adversely affect the security interest granted hereunder to Secured Party), or the making of any levy, seizure or attachment thereof or thereon;

(f) a default by Debtor in the performance of any covenant, condition or provision of any loan documents between Debtor and Secured Party, or any document related thereto, that are currently in effect or will be entered into, and such default shall not be remedied for a period of thirty (30) days after the earlier of (i) written notice from Secured Party of such default or (ii) actual knowledge by Debtor of such default;

(g) a default by Debtor under any agreement with PNC Bank or any successor commercial lender;

(h) (i) Debtor’s dissolution or termination or (ii) the commencement of any proceeding under any bankruptcy or insolvency laws by Debtor or (iii) the commencement of any proceeding under any bankruptcy or insolvency laws against Debtor or by or against any guarantor, surety or endorser for Debtor that results in the entry of an order for relief or which remains undismissed, undischarged or unbonded for a period of sixty (60) days or more or (iv) Debtor shall make a general assignment for the benefit of its creditors; or (v) Debtor shall fail generally to pay its debts as they become due, or shall take any action in furtherance of any of the foregoing;

(i) any statement of the financial condition of Debtor or of any guarantor, surety or endorser of any liability of Debtor to Secured Party submitted to Secured Party by Debtor or any such guarantor, surety or endorser proves to be false in any material respect.

Debtor shall provide Secured Party with immediate written notice upon the occurrence of any Event of Default and of the circumstances relating to such Event of Default.

3. Payment Obligations of Debtor.

(a) Debtor shall pay to Secured Party any sum or sums due or which may become due pursuant to the Note in accordance with the terms of the Note and the terms of this Agreement and any and all renewals, rearrangements or extensions of the Note.

(b) Debtor shall account fully and faithfully to Secured Party for proceeds from disposition of the Collateral in any manner and, following an Event of Default, shall pay or turn over promptly in cash, negotiable instruments, drafts, assigned accounts or chattel paper all the proceeds from each sale to be applied to Debtor’s Obligations to Secured Party, subject, if other than cash, to final payment or collection.

(c) Following an Event of Default hereunder or under the Note, Debtor shall pay to Secured Party on demand all reasonable expenses and expenditures (including, but not limited to, reasonable fees and expenses of legal counsel) incurred or paid by Secured Party in exercising or protecting its interests, rights and remedies under this Agreement, plus interest thereon at the Default Rate.

(d) Debtor shall pay immediately, in accordance with the terms of the Note, the entire unpaid balance of the Obligations of Debtor to Secured Party whether created or incurred pursuant to this Agreement or otherwise, upon an Event of Default.

4. Representations, Warranties and Covenants of Debtor.

(a) Other Liens. Except for the Security Interest, Debtor is the owner of the Collateral and its proceeds and will be the owner of the Collateral and its proceeds hereafter acquired free from unpaid charges, including taxes and free from any adverse lien, security interest or encumbrance (other than purchase money security interests that will be discharged upon Debtor’s payment of the purchase price for the applicable property), and Debtor will defend the Collateral against the claims and demands of all persons at any time claiming the same or any interest therein. No financing statements covering any Collateral or any proceeds thereof are on file in any public office and no third party is holding any Collateral to perfect its interest therein.

(b) Further Documentation. At any time and from time to time, upon the written request of Secured Party, and at the sole expense of Debtor, Debtor will promptly and duly execute and deliver such further instruments and documents and take such further action as Secured Party may reasonably request for the purpose of obtaining or preserving the full benefits of this Agreement and of the rights, remedies and powers herein granted, including, without limitation, filing any financing or continuation statements under the Uniform Commercial Code (the “UCC”) in effect in any jurisdiction with respect to the liens created hereby or taking any other action necessary to perfect the Security Interest. Debtor also hereby authorizes Secured Party to file any such financing or continuation statement without the signature of Debtor to the extent permitted by applicable law. A reproduction of this Agreement shall be sufficient as a financing statement (or as an exhibit to a financing statement on form UCC-1) for filing in any jurisdiction.

(c) Indemnification. Debtor agrees to defend, indemnify and hold harmless Secured Party against any and all liabilities, costs and expenses (including, without limitation, legal fees and expenses): (i) with respect to, or resulting from, any delay in paying, any and all excise, sales or other taxes which may be payable or determined to be payable with respect to any of the Collateral, (ii) with respect to, or resulting from, any delay in complying with any law, rule, regulation or order of any governmental authority applicable to any of the Collateral, or (iii) in connection with any of the transactions contemplated by this Agreement.

(d) Maintenance of Records. Debtor will keep and maintain at its own cost and expense accurate and complete records of the Collateral and its proceeds.

(e) Inspection Rights. Secured Party may enter Debtor’s premises at any reasonable time without interruption of Debtor’s business and without any breach of the peace to inspect the Collateral and all the books, correspondence and other records of Debtor relating to the Collateral, and Secured Party or its representatives may examine such records and make photocopies or otherwise take extracts from such records. Debtor agrees to render to Secured Party, at Debtor’s expense, such clerical and other assistance as may be reasonably requested with regard to the exercise of its rights pursuant to this paragraph.

(f) Compliance with Laws, etc. Debtor will comply in all material respects with all laws, rules, regulations and orders of any governmental authority applicable to any part of the Collateral or to the operation of Debtor’s business; provided, however, that Debtor may in good faith contest any non-compliance with such law, rule, regulation or order in any reasonable manner which does not and could not be reasonably deemed to, adversely affect Secured Party’s rights or the priority of its liens on the Collateral.

(g) Payment of Obligations. Debtor will pay promptly when due all taxes, assessments, charges, liens or levies imposed upon the Collateral or with respect to any of its income or profits derived from the Collateral, as well as all claims of any kind (including, without limitation, claims for labor, materials and supplies) against or with respect to the Collateral, except that no such charge need be paid if (i) the validity of such charge is being contested in good faith by appropriate proceedings, (ii) such proceedings do not involve any material danger of the sale, forfeiture or loss of any of the Collateral or any interest in the Collateral and (iii) such charge is adequately reserved against on Debtor’s books in accordance with generally accepted accounting principles.

(h) Limitation on Liens on Collateral. Debtor will not create, incur or permit to exist, will defend the Collateral against, and will take such other action as is necessary to remove, any lien or claim on or to the Collateral, other than the Security Interest, and will defend the right, title and interest of Secured Party in and to any of the Collateral against the claims and demands of all other persons.

(i) Limitations on Dispositions of Collateral. Debtor will not sell, transfer, lend, license, lease or otherwise dispose of any of the Collateral or any interest therein, or attempt, offer or contract to do so; provided, however, that Debtor will be allowed to grant licenses to its products and related documentation in the ordinary course of business and to establish or provide for escrows of related intellectual property in connection therewith. The Collateral shall remain in Debtor’s possession or control at all times at Debtor’s risk of loss until (i) sold, licensed or otherwise disposed of in the ordinary course of business, provided that Secured Party shall be granted a security interest in the proceeds and other consideration received for such Collateral, or (ii) as authorized in writing by Secured Party.

(j) Further Identification of Collateral. Debtor will furnish to Secured Party from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Secured Party may reasonably request, all in reasonable detail.

(k) Chief Executive Office. The location where Debtor maintains its chief executive office is County Line Industrial Park, 125 James Way, Southampton, PA ###-###-####. Debtor will promptly notify Secured Party in writing of any change in the location of its chief executive office. Substantially all of the tangible assets of Debtor will be held at its chief executive office.

(l) Insurance. Debtor will have and maintain adequate insurance at all times with respect to all Collateral against risks of fire, theft and such other risks as Secured Party may reasonably request. Within ten (10) days after the date hereof, Debtor shall amend such insurance policies, if necessary, to contain a standard mortgagee’s endorsement providing for payment of any loss to Secured Party and to provide for ten (10) days’ written minimum cancellation notice to Secured Party. Debtor shall furnish Secured Party evidence of compliance with the foregoing insurance provisions before February 28, 2009.

(m) Information. All information in any financial, credit or accounting statement (and any statement by Debtor related thereto) provided to Secured Party prior to, contemporaneously with or subsequent to the execution of this Agreement is and shall be true, correct, complete, valid and genuine in all material respects.

(n) Accounts. As to that portion of the Collateral which is accounts, Debtor represents, warrants and agrees with respect to each such account that:

(i) The account arose from the performance of services (including without limitation the granting of any licenses or sales of databases and/or information derived therefrom) which have been fully and satisfactorily performed or from the lease or the absolute sale of goods, if any, by Debtor in which Debtor had the sole and complete ownership, and the goods have been shipped or delivered to the account debtor.

(ii) The account is not subject to any prior or subsequent assignment, claim, lien or security interest other than that of Secured Party.

(iii) The account is not subject to set-off, counterclaim, defense, allowance or adjustment other than discounts for prompt payment shown on the invoice, or to dispute, objection or complaint by the account debtor concerning his liability on the account, and the goods, the sale or lease of which gave rise to the account, have not been returned, rejected, lost or damaged.

(iv) The account arose in the ordinary course of Debtor’s business, and no notice of bankruptcy, insolvency or financial embarrassment of the account debtor has been received by Debtor.

5. Secured Party’s Appointment as Attorney-in-Fact.

(a) Powers. Debtor hereby appoints Secured Party, and any officer or agent of Secured Party, with full power of substitution, as its attorney-in-fact with full irrevocable power and authority in the place of Debtor and in the name of Debtor or in its own name, from time to time in Secured Party’s discretion so long as an Event of Default has occurred and is continuing, for the purpose of carrying out the terms of this Agreement, to take any and all

appropriate action and to execute any instrument which may be necessary or desirable to accomplish the purposes of this Agreement. Without limiting the foregoing, so long as an Event of Default has occurred and is continuing, Secured Party shall have the right, without notice to, or the consent of, Debtor, to do any of the following on Debtor’s behalf:

(i) to pay or discharge any taxes, assessments, charges, liens or levies levied or placed on or threatened against the Collateral;

(ii) to direct any party liable for any payment under any of the Collateral to make payment of any and all amounts due or to become due thereunder directly to Secured Party or as Secured Party directs;

(iii) to ask for or demand, collect, and receive payment of and receipt for, any payments due or to become due at any time in respect of or arising out of any Collateral;

(iv) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to enforce any right in respect of any Collateral;

(v) to defend any suit, action or proceeding brought against Debtor with respect to any Collateral;

(vi) to settle, compromise or adjust any suit, action or proceeding described in subsection (v) above and, to give such discharges or releases in connection therewith as Secured Party may deem appropriate;

(vii) to assign any patent, trademark or copyright included in the Collateral of Debtor (along with the goodwill of the business to which any such patent, trademark or copyright pertains), throughout the world for such term or terms, on such conditions, and in such manner, as Secured Party shall in his sole discretion determine;

(viii) generally, to sell, transfer, pledge and make any agreement with respect to or otherwise deal with any of the Collateral, and to take, at Secured Party’s option and Debtor’s expense, any actions which Secured Party shall deem necessary to protect, preserve or realize upon the Collateral and Secured Party’s lien on the Collateral and to carry out the intent of this Agreement, in each case to the same extent as if Secured Party were the absolute owner of the Collateral for all purposes; and

(ix) to obtain, adjust, settle and cancel such insurance and endorsing any drafts drawn by insurers of the Collateral. Secured Party may apply any proceeds of such insurance which may be received by them in payment on account of the obligations secured hereby, whether due or not.

Debtor hereby ratifies whatever actions Secured Party shall lawfully do or cause to be done in accordance with this Section 5. This power of attorney shall be a power coupled with an interest and shall be irrevocable.

(b) No Duty on Secured Party’s Part. The powers conferred on Secured Party by this Section 5 are solely to protect Secured Party’s interests in the Collateral and shall

not impose any duty upon it to exercise any such powers. Secured Party shall be accountable only for amounts that he actually receives as a result of the exercise of such powers, and neither Secured Party nor any of his employees or agents shall, in the absence of willful misconduct or gross negligence, be responsible to Debtor for any act or failure to act pursuant to this Section 5.

6. Performance by Secured Party of Debtor’s Obligations. If Debtor fails to perform or comply with any of its agreements or covenants contained in this Agreement and Secured Party performs or complies, or otherwise causes performance or compliance, with such agreement or covenant in accordance with the terms of this Agreement, then the reasonable expenses of Secured Party incurred in connection with such performance or compliance shall be payable by Debtor to Secured Party on demand with interest thereon at the rate specified in Section 3(c) and shall constitute Obligations secured by this Agreement.

7. Remedies. If an Event of Default has occurred and is continuing, Secured Party may exercise, in addition to all other rights and remedies granted to him in this Agreement and in any other instrument or agreement relating to the Obligations, all rights and remedies of a secured party under the UCC in effect in the local jurisdiction where the Collateral is located. Without limiting the foregoing, Secured Party, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice which may not be waived by law) to or upon Debtor or any other person (all of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances collect, receive, appropriate and realize upon any or all of the Collateral, and/or may sell, lease, assign, give an option or options to purchase, or otherwise dispose of and deliver any or all of the Collateral (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of Secured Party or elsewhere upon such terms and conditions as Secured Party may deem advisable, for cash or on credit or for future delivery without assumption of any credit risk. Secured Party shall have the right upon any such public sale or sales, and, to the extent permitted by law, upon any such private sale or sales, to purchase all or any part of the Collateral so sold, free of any right or equity of redemption in Debtor, which right or equity is hereby waived or released. Secured Party shall apply the net proceeds of any such collection, recovery, receipt, appropriation, realization or sale, after deducting all reasonable expenses incurred therein or in connection with the care or safekeeping of any of the Collateral or in any way relating to the Collateral or the rights of Secured Party under this Agreement (including, without limitation, reasonable attorneys’ fees and expenses), to the payment in whole or in part of the Obligations, in such order as Secured Party may elect, and only after such application and after the payment by Secured Party of any other amount required by any provision of law, if any surplus remains, to Debtor or whoever may be lawfully entitled thereto. To the extent permitted by applicable law, Debtor waives all claims, damages and demands it may acquire against Secured Party arising out of the exercise by Secured Party of any of its rights hereunder. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least five (5) days before such sale or other disposition, unless the Collateral is perishable or threatens to decline quickly in value or is of a type customarily sold on a recognized market, in which case notice need not be given. Debtor shall remain liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Obligations, including without limitation the fees and disbursements of any attorneys employed by Secured Party to collect such deficiency.

8. Limitation on Duties Regarding Preservation of Collateral. The sole duty of Secured Party with respect to the custody, safekeeping and preservation of the Collateral, under the Pennsylvania Uniform Commercial Code or otherwise, shall be to deal with it in good faith. Neither Secured Party nor any of his employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of Debtor or otherwise.

9. Powers Coupled with an Interest. All authorizations and agencies contained in this Agreement with respect to the Collateral are irrevocable and powers coupled with an interest.

10. No Waiver; Cumulative Remedies. Secured Party shall not by any act (except by a written instrument pursuant to Section 11(a) hereof), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default under the Note or in any breach of any of the terms and conditions of this Agreement. No failure to exercise, nor any delay in exercising, on the part of Secured Party, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by Secured Party of any right or remedy under this Agreement on any one occasion shall not be construed as a bar to any right or remedy which Secured Party would otherwise have on any subsequent occasion. The rights and remedies provided in this Agreement are cumulative, may be exercised singly or concurrently and are not exclusive of any rights or remedies provided by law.

11. Miscellaneous.

(a) Amendments and Waivers. Any term of this Agreement may be amended or waived only with the written consent of Debtor and Secured Party. Any amendment or waiver effected in accordance with this Section 11(a) shall be binding upon the parties hereto and their respective successors and assigns.

(b) Transfer; Successors and Assigns. The rights and obligations of Secured Party and Debtor hereunder may not be transferred or assigned by any party without the prior written consent of the other parties hereto, except Secured Party may transfer or assign his rights and obligations under this Agreement to any corporation, partnership, limited liability company or limited liability partnership owned or controlled by Secured Party, or any shareholders, directors, executive officers, affiliates, partners or limited partners thereof or of Secured Party or a registered investment company with a common advisor and in such case the assignee shall be entitled to all of the rights, privileges and remedies granted in this Agreement to Secured Party provided that the transfer does not violate applicable securities laws; and is in connection with a concurrent assignment or transfer of the Note held by Secured Party to such assignee or transferee; and in such event Debtor will assert no claims or defenses, other than a defense that it has performed its obligations under the Note and this Agreement, it may have against Secured Party against the assignee, except those granted in this Agreement. Any permitted assignee of Debtor or Secured Party shall agree in writing prior to the effectiveness of such assignment to be bound by the provisions hereof. All of the stipulations, promises and

agreements in this Agreement made by or on behalf of Debtor shall bind the successors and permitted assigns of Debtor, whether so expressed or not, and inure to the benefit of the successors and permitted assigns of Debtor and Secured Party.

(c) Governing Law; Consent to Jurisdiction. This Agreement shall be governed by the laws of the Commonwealth of Pennsylvania without regard to the conflict of law provisions thereof. Debtor irrevocably and unconditionally agrees that any suit, action or other legal proceeding arising out of this Agreement may be brought in the courts of record in Montgomery County, Commonwealth of Pennsylvania, or the United States District Court for the Eastern District of Pennsylvania; consents to personal jurisdiction in each such court in any such suit, action or proceeding; and waives any objection concerning venue with respect to any suit, action or proceeding in any of such courts.

(d) WAIVER OF JURY TRIAL. DEBTOR IRREVOCABLY WAIVES ANY AND ALL RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR CLAIM OF ANY NATURE RELATING TO THIS AGREEMENT, ANY DOCUMENTS EXECUTED IN CONNECTION WITH THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED IN ANY OF SUCH DOCUMENTS. DEBTOR ACKNOWLEDGES THAT THE FOREGOING WAIVER IS KNOWING AND VOLUNTARY.

(e) CONFESSION OF JUDGMENT. DEBTOR HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY OF RECORD, OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF PENNSYLVANIA OR ELSEWHERE, TO APPEAR FOR DEBTOR AT ANY TIME OR TIMES, AFTER THE OCCURRENCE OF AN EVENT OF DEFAULT UNDER THIS AGREEMENT, OR THE NOTE, IN ANY SUCH COURT IN ANY ACTION BROUGHT AGAINST DEBTOR BY SECURED PARTY WITH RESPECT TO THE AGGREGATE AMOUNTS PAYABLE HEREUNDER, WITH OR WITHOUT DECLARATION FILED, AS OF ANY TERM, AND THEREIN TO CONFESS OR ENTER JUDGMENT AGAINST DEBTOR FOR ALL SUMS PAYABLE BY DEBTOR TO SECURED PARTY HEREUNDER, AS EVIDENCED BY AN AFFIDAVIT SIGNED BY A DULY AUTHORIZED DESIGNEE OF SECURED PARTY SETTING FORTH SUCH AMOUNT THEN DUE FROM DEBTOR TO SECURED PARTY, PLUS AN ATTORNEY’S COMMISSION EQUAL TO TEN PERCENT (10%) OF THE SUMS THEN OUTSTANDING UNDER THIS NOTE, BUT IN NO EVENT LESS THAN $10,000, WITH COSTS OF SUIT, RELEASE OF PROCEDURAL ERRORS, OTHER THAN NOTICES THAT MAY BE REQUIRED HEREUNDER, AND WITHOUT RIGHT OF APPEAL. IF A COPY OF THIS NOTE, VERIFIED BY AN AFFIDAVIT, SHALL HAVE BEEN FILED IN SUCH ACTION, IT SHALL NOT BE NECESSARY TO FILE THE ORIGINAL AS A WARRANT OF ATTORNEY. DEBTOR WAIVES THE RIGHT TO ANY STAY OF EXECUTION, THE BENEFIT OF ALL EXEMPTION LAWS NOW OR HEREAFTER IN EFFECT AND ANY AND ALL RIGHTS TO PRIOR NOTICE AND HEARING WITH RESPECT TO THE GARNISHMENT OR ATTACHMENT OF ANY PROPERTY PURSUANT TO A JUDGMENT ENTERED HEREUNDER.

April 23, 2009 (Original Warrant Date: February 20, 2009)		Warrant to Purchase Shares of Common Stock

ENVIRONMENTAL TECTONICS CORPORATION
AMENDED AND RESTATED COMMON STOCK WARRANT

THIS CERTIFIES THAT, for value received, H.F.

This Amended and Restated Common Stock Warrant (this “Warrant”) amends and restates in its entirety and replaces the Common Stock Warrant issued to the Holder by the Company on February 20, 2009. This Warrant has been issued pursuant to, and subject to the terms of, that certain Secured Promissory Note, dated as of February 20, 2009, issued by the Company to the Holder (the “Note”). The term “Warrant Shares”, as used herein, refers to the shares of Common Stock purchasable hereunder. The term “Warrants” means this Warrant and any warrants issued as a result of the transfer, exchange or replacement of such warrants. Capitalized terms not otherwise defined herein shall have the meanings given to such terms in the Note.

This Warrant is subject to the following terms, provisions and conditions:

During the Exercise Period, the Holder shall be entitled to purchase 143,885 shares of Common Stock under this Warrant; provided, however, that if the Shareholder Approval (as hereinafter defined) is not obtained by the Shareholder Approval Date (as hereinafter defined), the Holder shall be entitled to purchase 719,424 shares of Common Stock under this Warrant, unless the Company repays in full all principal, accrued interest and all other amounts payable under the Note on or before the Shareholder Approval Date.

2. Exercise Price. The exercise price of this Warrant (the “Exercise Price”) shall be a price per share equal to $1.39; provided, however, that if the Shareholder Approval is not obtained by the Shareholder Approval Date, the Exercise Price shall be $0.69 per share, unless the Company repays in full all principal, accrued interest and all other amounts payable under the Note on or before the Shareholder Approval Date.

5. Certain Agreements of the Company. The Company hereby covenants and agrees as follows:

law or otherwise, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the Holder of this Warrant in order to protect the exercise privilege of the Holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant.

(e) Successors and Assigns. This Warrant will be binding upon any entity succeeding to the Company or its assets.

EP₂ = EP₁* (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

(b) “EP₁” shall mean the Exercise Price of the Common Stock in effect immediately prior to such issuance of Securities;

Such notice shall also specify the date on which the holders of Common Stock shall be entitled to receive such dividend, distribution, or subscription rights or to exchange their Common Stock for stock or other securities or property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding-up, as the case may be. Such notice shall be given at least ten (10) business days prior to the record date or the date on which the Company’s books are closed in respect thereto. Failure to give any such notice or any defect therein shall not affect the validity of the proceedings referred to in clauses (i), (ii) and (iii) above; provided that if notice is not given in accordance with this Section 6(i), the Company will use its best efforts to insure that the Holder of this Warrant shall nevertheless receive the same rights and benefits received by other holders of securities of the Company from the proceedings referred to in clauses (i), (ii) and (iii) above, unless the Holder of this Warrant chooses not to receive such rights and benefits.
