4.2. Deposit Accounts. For each deposit account (each, a “Deposit Account”) that any Grantor at any time opens or maintains at any depository bank (each, a “Depository Bank”), the Grantor shall, at the Purchasers’ request and option, pursuant to an agreement in form and substance satisfactory to the Purchasers (each, a “Deposit Account Control Agreement”), upon an Event of Default either (a) cause the Depositary Bank to agree to comply at any time with instructions from the Purchasers to such Depositary Bank directing the disposition of funds from time to time credited to such Deposit Account, without further

consent of the Grantor, or (b) arrange for the Purchasers to become the customers of the Depositary Bank with respect to the Deposit Account, with the Grantors being permitted, only with the consent of the Purchasers, to exercise rights to withdraw funds from such Deposit Account. The Purchasers agree with the Grantors that the Purchasers shall not give any such instructions or withhold any withdrawal rights from the Grantors, unless an Event of Default has occurred and is continuing, or, after giving effect to any withdrawal not otherwise permitted by the Transaction Documents, would occur. The provisions of this paragraph shall not apply to (i) any Deposit Account for which the Grantors, the Depositary Bank and the Purchasers have entered into a cash collateral agreement specially negotiated among any Grantor, the Depositary Bank and the Purchasers for the specific purpose set forth therein (ii) Deposit Accounts for which any Purchaser is the depositary, and (iii) any Deposit Account which holds exclusively sales tax and/or withholding remittances.

If any Grantor shall at any time hold or acquire any certificated securities, the Grantor shall forthwith endorse, pledge and deliver the same to the Purchasers, accompanied by such instruments of transfer or assignment duly executed in blank as the Purchasers may from time to time specify. If any securities now or hereafter acquired by any Grantor are uncertificated and are issued to the Grantor or its nominee directly by the issuer thereof, the Grantor shall immediately notify the Purchasers thereof and, at the Purchasers’ request and option, pursuant to an agreement in form and substance satisfactory to the Purchasers, either (a) cause the issuer to agree to comply with instructions from the Purchasers as to such securities, without further consent of the Grantor or such nominee, or (b) arrange for the Purchasers to become the registered owners of the securities. If any securities, whether certificated or uncertificated, or other investment property now or hereafter acquired by any Grantor are held by the Grantor or its nominee through a securities intermediary or commodity intermediary, the Grantor shall immediately notify the Purchasers thereof and, at the Purchasers’ request and option, pursuant to an agreement in form and substance satisfactory to the Purchasers, either (i) cause such securities intermediary or (as the case may be) commodity intermediary to agree to comply with entitlement orders or other instructions from the Purchasers to such securities intermediary as to such securities or other investment property, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Purchasers to such commodity intermediary, in each case without further consent of the Grantor or such nominee, or (ii) in the case of financial assets or other investment property held through a securities intermediary, arrange for the Purchasers to become the entitlement holders with respect to such investment property, with the Grantor being permitted, only with the consent of the Purchasers, to exercise rights to withdraw or otherwise deal with such investment property. The Purchasers agree with the Grantors that the Purchasers shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by the Grantors,

unless an Event of Default has occurred and is continuing, or, after giving effect to any such investment and withdrawal rights not otherwise permitted by the Transaction Documents, would occur.

The Purchasers agree with the Grantors that the Purchasers will arrange, pursuant to procedures satisfactory to the Purchasers and so long as such procedures will not result in the Purchasers’ loss of control, for the Grantors to make alterations to the electronic chattel paper or transferable record permitted under UCC §9-105, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by the Grantors with respect to such electronic chattel paper or transferable record.

4.6. Letter-of-credit Rights. If any Grantor is at any time a beneficiary under a letter of credit now or hereafter issued in favor of the Grantor, the Grantor shall promptly notify the Purchasers thereof and, at the request and option of the Purchasers, the Grantor shall, pursuant to an agreement in form and substance satisfactory to the Purchasers, either (i) use commercially reasonable efforts (including, but not limited to, the payment of customary transfer and assignment fees) to have the issuer and any confirmer of such letter of credit to consent to an assignment to the Purchasers of the proceeds of any drawing under the letter of credit or (ii) use commercially reasonable efforts (including, but not limited to, the payment of customary transfer and assignment fees) to have the Purchasers become the transferee beneficiaries of the letter of credit, with the Purchasers agreeing, in each case, that the proceeds of any drawing under the letter to credit are to be applied as provided in the Note.

11. Insurance.

11.1. Maintenance of Insurance. Each Grantor will maintain with financially sound and reputable insurers insurance with respect to its properties and business against such casualties and contingencies as shall be in accordance with general practices of businesses engaged in similar activities in similar geographic areas; provided, however, that the Borrower shall at all times maintain with financially sound and reputable insurers such insurance in amounts not less than the insurance maintained by the Borrower as of the date hereof, except with the Purchasers’ prior written consent (which will not be unreasonably withheld or delayed). Such insurance shall be in such minimum amounts that the Grantor will not be deemed a coinsurer under applicable insurance laws, regulations and policies and otherwise shall be in such amounts, contain such terms, be in such forms and be for such periods as may be reasonably satisfactory to the Purchasers. In addition, all such insurance shall be payable to the Purchasers as loss payee.

11.2. Insurance Proceeds. The proceeds of any casualty insurance in respect of any casualty loss of any of the Collateral shall, subject to the rights, if any, of other parties with a prior interest in the property covered thereby, (i) so long as no Default or Event of Default has occurred and is continuing and to the extent that the amount of such proceeds is less than $150,000, be disbursed to the Grantor for direct application by the Grantor solely to the repair or replacement of the Grantor’s property so damaged or destroyed and (ii) in all other circumstances, be held by the Purchasers as cash collateral for the Obligations and (except to the extent disbursed pursuant to the next sentence) may be applied to the Obligations. The Purchasers may, at their sole option, disburse from time to time all or any part of such proceeds so held as cash collateral (in an interest-bearing account, provided that the Grantor shall execute and deliver to the Purchasers a properly completed Form W-9), upon such terms and conditions as the Purchasers may reasonably prescribe, for direct application by the Grantor solely to the repair or replacement of the Grantor’s property so damaged or destroyed, or the Purchasers may apply all or any part of such proceeds to the Obligations.

11.3. Notice of Cancellation etc. All policies of insurance shall provide for at least 30 days prior written cancellation notice to the Purchasers, unless a shorter period is mandated under applicable law. In the event of failure by any Grantor to provide and maintain insurance as herein provided, the Purchasers may, at their option, provide such insurance and charge the amount thereof to the Grantor. Each Grantor shall furnish the Purchasers with certificates of insurance and policies evidencing compliance with the foregoing insurance provision.

12. Collateral Protection Expenses; Preservation of Collateral.

12.1. Expenses Incurred by Purchasers. In their discretion, the Purchasers may discharge encumbrances at any time levied or placed on any of the Collateral (other than to the extent constituting Permitted Liens), make repairs thereto and pay any necessary filing fees or, if any Grantor fails to do so, insurance premiums. Each Grantor agrees to reimburse the Purchasers on demand for any and all expenditures so made. The Purchasers shall have no obligation to the Grantors to make any such expenditures, nor shall the making thereof relieve the Grantor of any default. Any expenses incurred under this Section 12 shall constitute Obligations.

12.2. Purchasers’ Obligations and Duties. Anything herein to the contrary notwithstanding, each Grantor shall remain liable under each contract or agreement comprised in the Collateral to be observed or performed by the Grantor thereunder. The Purchasers shall not have any obligation or liability under any such contract or agreement by reason of or arising out of this Agreement or the receipt by the Purchasers of any payment relating to any of the Collateral, nor shall the Purchasers be obligated in any manner to perform any of the obligations of the Grantor under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment received by the Purchasers in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, 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 the Purchasers or to which the Purchasers may be entitled at any time or times. The Purchasers’ sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in their possession, under §9-207 of the Uniform Commercial Code of the State or otherwise, shall be to deal with such Collateral in the same manner as the Purchasers deal with similar property for their own accounts.

13. Securities and Deposits. The Purchasers may at any time following and during the continuance of an Event of Default, at their option, transfer to themselves or any nominee any securities constituting Collateral, receive any income thereon and hold such income as additional Collateral or apply it to the Obligations. Whether or not any

Obligations are due, the Purchasers may following and during the continuance of an Event of Default demand, xxx for, collect, or make any settlement or compromise which it deems desirable with respect to the Collateral. Regardless of the adequacy of Collateral or any other security for the Obligations, any deposits or other sums at any time credited by or due from the Purchasers to the Grantors may at any time be applied to or set off against any of the Obligations then due and owing.

14. Notification to Account Debtors and Other Persons Obligated on Collateral. If an Event of Default shall have occurred and be continuing, the Grantors shall, at the request of the Purchasers, notify account debtors and other persons obligated on any of the Collateral of the security interest of the Purchasers in any account, chattel paper, general intangible, instrument or other Collateral and that payment thereof is to be made directly to the Purchasers or to any financial institution designated by the Purchasers as their agent therefor, and the Purchasers may themselves, if an Event of Default shall have occurred and be continuing, without notice to or demand upon the Grantor, so notify account debtors and other persons obligated on Collateral. After the making of such a request or the giving of any such notification, the Grantors shall hold any proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by the Grantor as trustee for the Purchasers without commingling the same with other funds of the Grantor and shall turn the same over to the Purchasers in the identical form received, together with any necessary endorsements or assignments. The Purchasers shall apply the proceeds of collection of accounts, chattel paper, general intangibles, instruments and other Collateral received by the Purchasers to the Obligations, such proceeds to be immediately entered after final payment in cash or other immediately available funds of the items giving rise to them.

15. Investment Property. (i) The Grantors, at their cost and expense (including the cost and expense of any of the following referenced consents, approvals etc.) will promptly execute and deliver or cause the execution and delivery of all applications, certificates, instruments, registration statements, and all other documents and papers the Purchasers may request during the continuance of an Event of Default in connection with the obtaining of any consent, approval, registration, qualification, permit, license, accreditation, or authorization of any other official body or other Person necessary or appropriate for the effective exercise of any rights hereunder or under the other Transaction Documents. Without limiting the generality of the foregoing, the Grantors agree that in the event the Purchasers shall exercise their rights hereunder or pursuant to the other Transaction Documents during the continuance of an Event of Default, to sell, transfer, or otherwise dispose of, or vote, consent, operate, or take any other action in connection with any of the Collateral, the Grantors shall execute and deliver (or cause to be executed and delivered) all applications, certificates, assignments and other documents that the Purchasers request to facilitate such actions and shall otherwise promptly, fully, and diligently cooperate with the Purchasers and any other Persons in making any application for the prior consent or approval of any official body or any other Person to the exercise by the Purchasers of any such rights relating to all or any of the Collateral.

(ii) The Grantors agree promptly upon the occurrence and continuance of an Event of Default and without any request therefor by the Purchasers, so long as such Event of Default shall continue, to deliver (properly endorsed where required hereby or requested by Purchasers) to the Purchasers all Dividends and Distributions with respect to Investment Property and all proceeds of the Collateral, in each case thereafter received by the Grantor, all of which shall be held by Purchasers as additional Collateral.

(iii) Except when an Event of Default has occurred and is continuing, the Grantors may continue to vote all Investment Property included in the Collateral except in a manner which is inconsistent or in violation of the Transaction Documents. The Grantors agree promptly upon the occurrence and during the continuance of an Event of Default, (i) that Purchasers may exercise (to the exclusion of the Grantor) the voting power and all other incidental rights of ownership with respect to any Collateral constituting Investment Property of the Grantor and the Grantor hereby grants Purchasers an irrevocable proxy, exercisable under such circumstances, to vote such Investment Property; and (ii) that it shall promptly deliver to the Purchasers such additional proxies and other documents as may be necessary to allow the Purchasers to exercise such voting power.

(iv) All Dividends, Distributions, interest, principal, cash payments, payment intangibles and proceeds which may at any time and from time to time be held by any Grantor but which the Grantor is then obligated to deliver to the Purchasers, shall, until delivery to the Purchasers, be held by the Grantor separate and apart from its other property in trust for the Purchasers. The Purchasers agree that unless an Event of Default shall have occurred and be continuing, the Grantors will have the exclusive voting power with respect to any Investment Property constituting the Grantor’s Collateral and the Purchasers will, upon the written request of any Grantor, promptly deliver such proxies and other documents, if any, as shall be reasonably requested by the Grantor which are necessary to allow the Grantor to exercise that voting power; provided that no vote shall be cast, or consent, waiver, or ratification given, or action taken by the Grantor that would violate any provision of any Transaction Document.

The Grantors hereby acknowledge that the sale by Purchasers of any Investment Property pursuant to the terms hereof in compliance with the Securities Act, as well as applicable “Blue Sky” or other state securities laws may require strict limitations as to the manner in which Purchasers or any subsequent transferee of the Investment Property may dispose thereof. The Grantors acknowledge and agree that, to protect Purchasers’ interests, it may be necessary to sell the Investment Property at a price less than the maximum price attainable if a sale were delayed or made in another manner, such as a public offering under the Securities Act. The Grantors do not have an objection to a sale in such manner and the Grantors agree that Purchasers do not have an obligation to obtain the maximum possible price for all or any part of the Investment Property. Without limiting the generality of the foregoing, the Grantors agree that Purchasers may, pursuant to the terms hereof and subject to applicable law, from time to time attempt to sell all or any part of the Investment Property by a private placement, restricting the bidders and prospective purchasers to those Persons who will represent and agree that they are

purchasing for investment only and not for distribution. In so doing, Purchasers may solicit offers to buy the Investment Property or any part thereof for cash from a limited number of investors deemed by Purchasers, in their reasonable judgment, to be institutional investors or other responsible Persons who might be interested in purchasing the Investment Property. If Purchasers shall solicit such offers, then acceptance by Purchasers of one of the offers shall be deemed to be a commercially reasonable method of disposition of the Collateral.

16. Power of Attorney.

16.1. Appointment and Powers of Purchasers. The Grantors hereby irrevocably constitute and appoint the Purchasers and any officer or 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 Grantors or in the Purchasers’ own name, 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 that may be necessary or desirable to accomplish the purposes of this Agreement and, without limiting the generality of the foregoing, hereby gives said attorney the power and right, on behalf of the Grantors, without notice to or assent by the Grantors, to do the following:

(a) upon the occurrence and during the continuance of an Event of Default, generally to sell, transfer, pledge, make any agreement with respect to or otherwise deal with any of the Collateral in such manner as is consistent with the Uniform Commercial Code of the State and as fully and completely as though the Purchasers were the absolute owners thereof for all purposes, and to do at the Grantors’ expense, at any time, or from time to time, all acts and things which the Purchasers deem necessary to protect, preserve or realize upon the Collateral and the Purchasers’ security interest therein, in order to effect the intent of this Agreement, all as fully and effectively as the Grantor might do, including, without limitation, (i) the filing and prosecuting of registration and transfer applications with the appropriate federal or local agencies or authorities with respect to trademarks, copyrights and patentable inventions and processes, (ii) upon written notice to the Grantors, the exercise of voting rights with respect to voting securities, which rights may be exercised, if the Purchasers so elect, with a view to causing the liquidation in a commercially reasonable manner of assets of the issuer of any such securities and (iii) the execution, delivery and recording, in connection with any sale or other disposition of any Collateral, of the endorsements, assignments or other instruments of conveyance or transfer with respect to such Collateral; and

(b) to the extent that the Grantors’ authorization given in §3 is not sufficient, to file such financing statements with respect hereto, with or without the Grantor’ signature, as the Purchasers may deem appropriate and to execute in the Grantor’s name such financing statements and amendments thereto and continuation statements which may require the Grantor’s signature.

16.2. Ratification by Grantors. To the extent permitted by law, the Grantors hereby ratify all that said attorney 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.

16.3. No Duty on Purchasers. The powers conferred on the Purchasers hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Purchasers shall be accountable only for the amounts that they actually receive as a result of the exercise of such powers and neither any Purchaser nor any of its officers, directors, employees or agents shall be responsible to the Grantor for any act or failure to act, except for such Purchaser’s own gross negligence or willful misconduct.

16.4. Purchasers hereby agree that they will not exercise any rights conferred by this Section 16 absent the occurrence of an Event of Default.

17. Remedies. If an Event of Default shall have occurred and be continuing, the Purchasers may, without notice to or demand upon the Grantors, declare this Agreement to be in default, and the Purchasers shall thereafter have in any jurisdiction in which enforcement hereof is sought, in addition to all other rights and remedies, the rights and remedies of a purchaser under the Uniform Commercial Code of the State or of any jurisdiction in which Collateral is located, including, without limitation, the right to take possession of the Collateral, and for that purpose the Purchasers may, so far as the Grantors can give authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom. The Purchasers may in their discretion require the Grantors to assemble all or any part of the Collateral at such location or locations within the jurisdiction(s) of the Grantors’ principal office(s) or at such other locations as the Purchasers may reasonably designate. Unless the Collateral is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market, the Purchasers shall give to the Grantors at least ten Business Days prior written notice of the time and place of any public sale of Collateral or of the time after which any private sale or any other intended disposition is to be made. The Grantors hereby acknowledge that ten Business Days prior written notice of such sale or sales shall be reasonable notice. In addition, the Grantors waive any and all rights that it may have to a judicial hearing in advance of the enforcement of any of the Purchasers’ rights hereunder, including, without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its rights with respect thereto.

18. Standards for Exercising Remedies. To the extent that applicable law imposes duties on the Purchasers to exercise remedies in a commercially reasonable manner, the Grantors acknowledge and agree that it is not commercially unreasonable for the Purchasers (a) to fail to incur expenses reasonably deemed significant by the

Purchasers to prepare Collateral for disposition or otherwise to complete raw material or work in process into finished goods or other finished products for disposition, (b) to fail to obtain third party consents for access to Collateral to be disposed of, or to obtain or, if not required by other law, to fail to obtain governmental or third party consents for the collection or disposition of Collateral to be collected or disposed of, (c) to fail to exercise collection remedies against account debtors or other persons obligated on Collateral or to remove liens or encumbrances on or any adverse claims against Collateral, (d) to exercise collection remedies against account debtors and other persons obligated on Collateral directly or through the use of collection agencies and other collection specialists, (e) to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, (f) to contact other persons, whether or not in the same business as the Grantor, for expressions of interest in acquiring all or any portion of the Collateral, (g) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the collateral is of a specialized nature, (h) to dispose of Collateral by utilizing Internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capability of doing so, or that match buyers and sellers of assets, (i) to dispose of assets in wholesale rather than retail markets, (j) to disclaim disposition warranties, (k) to purchase insurance or credit enhancements to insure the Purchasers against risks of loss, collection or disposition of Collateral or to provide to the Purchasers a guaranteed return from the collection or disposition of Collateral, or (1) to the extent deemed appropriate by the Purchasers, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Purchasers in the collection or disposition of any of the Collateral. The Grantors acknowledge that the purpose of this §18 is to provide non-exhaustive indications of what actions or omissions by the Purchasers would not be commercially unreasonable in the Purchasers’ exercise of remedies against the Collateral and that other actions or omissions by the Purchasers shall not be deemed commercially unreasonable solely on account of not being indicated in this §18. Without limitation upon the foregoing, nothing contained in this §18 shall be construed to grant any rights to the Grantors or to impose any duties on the Purchasers that would not have been granted or imposed by this Agreement or by applicable law in the absence of this §18.

19. No Oral Change; Amendments; Security Agreement Supplements for Additional Grantors. No amendment of any provision of this Agreement shall be effective unless it is in writing and signed by the Grantors and the Purchasers, and no waiver of any provision of this Agreement, and no consent to any departure by the Grantors therefrom, shall be effective unless it is in writing and signed by the Purchasers, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Notwithstanding the foregoing, additional Persons may become Grantors under this Agreement without consent of any other Grantor through execution and delivery to the Purchasers of an Assumption Agreement in the form of Annex 1 hereto or any other form of supplement acceptable to the Purchasers. Nothing in this Section 19 shall be construed to permit any Grantor to form a Subsidiary unless expressly permitted to do so under the Note.

20. Suretyship Waivers by Grantors. Each Grantor waives demand, notice, protest, notice of acceptance of this Agreement, notice of loans made, credit extended, Collateral received or delivered or other action taken in reliance hereon and all other demands and notices of any description. With respect to both the Obligations and the Collateral, the Grantors assent to any extension or postponement of the time of payment or any other indulgence, to any substitution, exchange or release of or failure to perfect any security interest in any Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement, compromising or adjusting of any thereof, all in such manner and at such time or times as the Purchasers may deem advisable. The Purchasers shall have no duty as to the collection or protection of the Collateral or any income thereon, nor as to the preservation of rights against prior parties, nor as to the preservation of any rights pertaining thereto beyond the safe custody thereof as set forth in §11.2. The Grantors further waive any and all other suretyship defenses.

21. Marshalling. The Purchasers shall not be required to marshal any present or future collateral security (including but not limited to this Agreement and the Collateral) for, or other assurances of payment of, the Obligations or any of them or to resort to such collateral security or other assurances of payment in any particular order, and all of its rights hereunder and in respect of such collateral security and other assurances of payment shall be cumulative and in addition to all other rights, however existing or arising. To the extent that it lawfully may, each Grantors hereby agrees that it will not invoke any law relating to the marshalling of collateral which might cause delay in or impede the enforcement of the Purchasers’ rights under this Agreement or under any other instrument creating or evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or payment thereof is otherwise assured, and, to the extent that it lawfully may, each Grantor hereby irrevocably waives the benefits of all such laws.

22. Proceeds of Dispositions; Expenses. The Grantors shall pay to the Purchasers on demand any and all expenses, including reasonable attorneys’ fees and disbursements, incurred or paid by the Purchasers in protecting, preserving or enforcing the Purchasers’ rights under or in respect of any of the Obligations or any of the Collateral. After deducting all of said expenses, the residue of any proceeds of collection or sale of the Obligations or Collateral shall, to the extent actually received in cash, be applied to the payment of the Obligations in such order or preference as the Purchasers may determine, proper allowance and provision being made for any Obligations not then due. Upon the final payment and satisfaction in full of all of the Obligations (other than indemnification obligations which have not matured as of the date thereof) and after making any payments required by Sections 9-608(a)(1)(C) or 9615(a)(3) of the Uniform Commercial Code of the State, any excess shall be returned to the Grantors, and the Grantors shall remain liable for any deficiency in the payment of the Obligations.

23. Overdue Amounts. Until paid, all amounts due and payable by the Grantors hereunder shall be a debt secured by the Collateral and shall bear, whether before or after judgment, interest at the rate of interest set forth in the Note.
