Secured Party shall have no obligation to inquire as to the sufficiency of any payment received by it on account of any of Debtor’s accounts receivable or to take any action to collect or enforce the payment of any account receivable.

4. Insurance. Debtor shall, at all times, maintain with financially sound and reputable insurers adequate insurance with respect to the Collateral. In addition to such requirements:

(c) Debtor shall cause Secured Party to be named as a loss payee and an additional insured (but without any liability for any premiums) under such insurance policies and Debtor shall obtain non-contributory lender’s loss payable endorsements to all insurance policies in form and substance satisfactory to Secured Party (such lender’s loss payable endorsements shall specify that the proceeds of such insurance shall be payable to Secured Party as its interests may appear and further specify that Secured Party shall be paid regardless of any act or omission by Debtor or any of its affiliates).

At its option, Secured Party may apply any insurance proceeds received by Secured Party at any time to the cost of repairs or replacement of Collateral and/or to payment of the Obligations, whether or not then due, in any order and in such manner as Secured Party may determine or hold such proceeds as cash collateral to secure the Obligations.

5. Further Assurances. At Secured Party’s request from time to time, the Debtor will execute and deliver or cause to be executed and delivered any and all such further agreements, instruments and documents and take such further actions as Secured Party may reasonably deem desirable to evidence, perfect, maintain and enforce the Secured Party’s security interests and the priority thereof in the Collateral and to otherwise effectuate the provisions or purposes of this Security Agreement and the other Loan Documents.

(a) occurrence of any Event of Default as defined in the Loan Agreement; and

(b) any failure of Debtor in the performance in any material respect of any of the terms or conditions of, or any breach of any material representation, covenant or warranty under, or any other material default under this Agreement.

7. Remedies Upon Default.

(a) Upon the occurrence and during the continuance of any Event of Default, and subject to (and without limitation of) the terms of the Loan Agreement (including, without limitation, the cure periods (if any) with respect to such Events of Default set forth therein):

(i) Secured Party may declare all Obligations secured hereby immediately due and payable and shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as now in effect in the Commonwealth of Massachusetts or under other applicable law.

(ii) Secured Party may notify Debtor’s account or contract debtors (or other obligors whose obligations to Debtor secure this agreement) of Secured Party’s security interest and that such account or contract debtors are to make payments directly to Secured Party. Secured Party may send this notice in Debtor’s name or in Secured Party’s name, and at Secured Party’s request Debtor will join in Secured Party’s notice, provide written confirmation of Secured Party’s security interest and request that payment be sent to Secured Party. Secured Party may enforce this obligation by specific performance. Secured Party may collect all amounts due on the accounts and accounts receivable. Upon and after notification by Secured Party to Debtor, Debtor shall hold any proceeds and collections of any of the collateral in trust for Secured Party and shall not commingle such proceeds or collections with any other of Debtor’s funds, and Debtor shall deliver all such proceeds to Secured Party immediately upon Debtor’s receipt thereof in the identical form received and duly endorsed or assigned to Secured Party.

(iii) with or without judicial process or the aid or assistance of others, Secured Party may enter upon any premises on or in which any of the Collateral may be located and take possession of the Collateral or complete processing, manufacturing and repair of all or any portion of the Collateral.

(iv) Secured Party may collect, foreclose, receive, appropriate, setoff and realize upon any and all Collateral.

(v) Secured Party may remove any or all of the Collateral from any premises on or in which the same may be located for the purpose of effecting the sale, foreclosure or other disposition thereof or for any other purpose.

(vi) Secured Party may sell, lease, transfer, assign, deliver or otherwise dispose of any and all Collateral (including entering into contracts with respect thereto, public or private sales at any exchange, broker’s board, at any office of Secured Party or elsewhere) at such prices or terms as Secured Party may deem reasonable, for cash, upon credit or for future delivery, with the Secured Party having the right to purchase the whole or any part of the Collateral at any such public sale, all of the foregoing being free from any right or equity of redemption of Debtor, which right or equity of redemption is hereby expressly waived and released by Debtor.

(vii) At the request of Secured Party, the Debtor shall cause the Collateral, or such portion of the Collateral as Secured Party may direct, to be assembled for Secured Party at such location (including, without limitation, Debtor’s business address) as Secured Party may request.

(viii) Secured Party may exercise any other rights and remedies that it may have under the other Loan Documents.

(b) If any of the Collateral is sold or leased by Secured Party upon credit terms or for future delivery, the Obligations shall not be reduced as a result thereof until payment therefor is finally collected by Secured Party. If notice of disposition of Collateral is required by law, ten (10) days prior notice by Secured Party to Debtor designating the time and place of any public sale or the time after which any private sale or other intended disposition of Collateral is to be made, shall be deemed to be reasonable notice thereof and Debtor waives any other notice. In the event Secured Party institutes an action to recover any Collateral or seeks recovery of any Collateral by way of prejudgment remedy, Debtor waives the posting of any bond which might otherwise be required. Any such sale may take place from Debtor’s location or such other location as Secured Party may designate.

(c) Debtor hereby irrevocably appoints Secured Party as its true and lawful attorney-in-fact with full power of substitution, effective upon the occurrence and continuation of an Event of Default, to take any of the foregoing actions set forth in this Section in the name of the Debtor or Secured Party to carry out the terms of this Agreement and to protect, enforce, preserve or perfect Secured Party’s rights hereunder and under the other Loan Documents. Such power of attorney is irrevocable and shall be deemed to be coupled with an interest.

(d) For the purpose of enabling Secured Party to exercise the rights and remedies hereunder, Debtor hereby grants to Secured Party, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to Debtor) to use, assign, license or sublicense any of the trademarks, service-marks, trade names, business names, trade styles, designs, logos and other source of business identifiers and other Intellectual Property and general intangibles now owned or hereafter acquired by Debtor, wherever the same maybe located, including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout thereof.

(e) Secured Party may apply the cash proceeds of Collateral actually received by Secured Party from any sale, lease, foreclosure or other disposition of the Collateral to payment of the Obligations, in whole or in part and in such order as Secured Party may elect, whether or not then due. Debtor shall remain liable to Secured Party for the payment of any deficiency with interest at the highest rate provided for in the Loan Agreement and, subject to the provisions of the Asset Purchase Agreement, all costs and expenses of collection or enforcement, including attorneys’ fees and legal expenses.

8. Waiver of Counterclaims. Debtor waives all rights to interpose any claims, deductions, setoffs or counterclaims of any nature (other then compulsory counterclaims) in any action or proceeding with respect to this Security Agreement, the other Loan Documents, the Obligations, the Collateral or any matter arising therefrom or relating hereto or thereto.

9. Miscellaneous. Subject to the provisions of the Asset Purchase Agreement, expenses of enforcing Secured Party’s rights hereunder including, but not limited to, Secured

Party’s reasonable attorneys’ fees and other expenses shall be payable by Debtor on demand and shall constitute Obligations hereunder. None of the terms or provisions of this Agreement may be waived, altered, modified or amended except by an instrument in writing, duly executed by Secured Party and Debtor. Secured Party’s rights and remedies hereunder or under any other agreement or instrument shall be cumulative, may be exercised singly or concurrently and are not exclusive of any other rights or remedies provided by law. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts. This Agreement shall be assignable by Secured Party without Debtor’s consent and shall be binding upon and shall inure to the benefit of Debtor and Secured Party and their respective successors and assigns; PROVIDED THAT Debtor may not assign or transfer any rights or obligations hereunder without Secured Party’s prior written consent. This Security Agreement is supplemental to the Loan Agreement (the terms of which, including, without limitation, the notice and governing law provisions, no waiver provisions and waiver of jury trial provisions, the Debtor expressly accepts, confirms and acknowledges are incorporated herein by reference). In the event of any irreconcilable conflict between the provisions of this Security Agreement and the Loan Agreement the provisions of the Loan Agreement shall control.
