Notwithstanding anything to the contrary contained herein, the requirement of the Debtors to grant any liens or security interests shall remain subject

-5-

in all respects to the provisions of Section 4.1 of the Credit Agreement. All terms which are used herein which are defined in the Uniform Commercial Code of the State of New York as in effect from time to time (“UCC”) shall have the same meanings herein as such terms are defined in the UCC, unless this Agreement shall otherwise specifically provide. For purposes of this Agreement, the term “Receivables” means all rights to the payment of a monetary obligation, whether or not earned by performance, and whether evidenced by an Account, Chattel Paper, Instrument, General Intangible, or otherwise.

(b) This Agreement is made and given to secure, and shall secure, the prompt payment and performance of (i) all “Obligations,” and all “Hedging Liability,” as such terms are defined in the Credit Agreement, including, without limitation, all obligations with respect to Loans made and to be made under the Credit Agreement (whether or not evidenced by Notes issued thereunder), all obligations of the Borrowers, or any of them individually, to reimburse the Secured Creditors for the amount of all drawings on all Letters of Credit issued pursuant to the Credit Agreement and all other obligations of the Borrowers, or any of them individually, under all Applications for Letters of Credit, all other obligations of the Borrowers and the other Debtors under the Loan Documents, all obligations of the Debtors, and of any of them individually, with respect to any Hedging Liability and the agreements relating thereto, and all obligations of the Debtors, and of any of them individually, arising under any guaranty issued by it relating to the foregoing or any part thereof, in each case whether now existing or hereafter arising (and whether arising before or after the filing of a petition in bankruptcy and including all interest, costs, fees, and charges after the entry of an order for relief against a Debtor in a case under Title 11 of the United States Bankruptcy Code or any similar proceeding, whether or not such interest, costs, fees and charges would be an allowed claim against such Debtor in such proceeding), due or to become due, direct or indirect, absolute or contingent, and howsoever evidenced, held or acquired, and owing in any currency and (ii) any and all expenses and charges, legal or otherwise, suffered or incurred by the Secured Creditors, and any of them individually, in collecting or enforcing any of such indebtedness, obligations, and liabilities or in realizing on or protecting or preserving any security therefor, including, without limitation, the lien and security interest granted hereby (all of the indebtedness, obligations, liabilities, expenses, and charges described above being hereinafter referred to as the “Obligations”). Notwithstanding anything in this Agreement to the contrary, the right of recovery against any Debtor under this Agreement (other than the Company to which this limitation shall not apply) shall not exceed $1.00 less than the lowest amount that would render such Debtor’s obligations under this Agreement void or voidable under applicable law, including fraudulent conveyance law.

Section 3. Covenants, Agreements, Representations and Warranties. Each Debtor hereby covenants and agrees with, and represents and warrants to, the Agent and each Secured Creditor that:

(a) Each Debtor is duly organized and validly existing in good standing under the laws of the state of its organization. No Debtor shall change its state of organization without first providing the Agent 15 days prior written notice. Each Debtor’s chief executive office and principal place of business is at the location listed opposite such Debtor’s name under column 2 on Schedule A attached hereto; and such Debtor has no other executive offices or places of business (other than operating job sites in the ordinary course of such Debtor’s business) other than those listed opposite such Debtor’s name under column 3 on Schedule A attached hereto. Each Debtor’s organizational

-6-

identification number is set forth under its name in column 1 on Schedule A attached hereto. The Collateral owned or leased by each Debtor is and shall remain in such Debtor’s possession or control at the locations listed opposite such Debtor’s name under column 4 on Schedule A attached hereto opposite such Debtors’ name, or is or shall be located at such Debtor’s then operating job sites in the ordinary course of its business, or is or shall be in transit to or between any of the foregoing locations (collectively, the “Permitted Collateral Locations”) in the ordinary course of business. If for any reason any Collateral is at any time kept or located at a location other than a Permitted Collateral Location, the Agent shall nevertheless have and retain a lien on and security interest in such Collateral. No Debtor shall move its chief executive office or maintain a place of business at a location other than those specified under columns 2 and/or 3 on Schedule A attached hereto other than temporarily in the ordinary course of business or permit any Collateral in excess of $50,000,000 to be located at a location other than a Permitted Collateral Location other than temporarily in the ordinary course of business or at a job site, in each case without first providing the Agent 15 days prior written notice of such Debtor’s intent to do so; provided, however, that each Debtor shall at all times maintain its chief executive office and places of business in the United States of America and, with respect to any new chief executive office or place of business or location of Collateral, such Debtor shall have taken all action reasonably requested by the Agent or any Secured Creditor to maintain the lien and security interest of the Agent in the Collateral at all times fully perfected and in full force and effect. The execution and delivery of this Agreement, and the observance and performance of each of the matters and things herein set forth, will not (i) contravene or constitute a default under any provision of law or any judgment, injunction, order or decree binding upon any Debtor or any provision of any Debtor’s organizational documents (e.g. certificate of incorporation, articles of incorporation, by‑laws, certificate of formation, limited liability company operating agreement or partnership agreement, as applicable) or any covenant, indenture or agreement of or affecting any Debtor or any of its property or (ii) result in the creation or imposition of any lien or encumbrance on any property of any Debtor except for the lien and security interest granted to the Agent in the Collateral hereunder. Each Debtor’s organizational registration number (if any) is set forth on Schedule A attached hereto.

(b) The Collateral and every part thereof is and shall be free and clear of all security interests, liens (including, without limitation, mechanics’, laborers’ and statutory liens), attachments, levies and encumbrances of every kind, nature and description and whether voluntary or involuntary, except for the lien and security interest of the Agent therein and other liens permitted by the Credit Agreement (herein, the “Permitted Encumbrances”).

(c) Subject to Sections 4(a), 6(c) and 7(a) hereof, no Debtor shall without the Agent’s prior written consent, sell, assign, mortgage, lease or otherwise dispose of the Collateral or any interest therein, except that (i) until an Event of Default has occurred and is continuing and thereafter until notified by the Agent that it intends to foreclose or otherwise realize upon such Collateral, each Debtor may use and lease its Collateral to the extent not prohibited by the terms of the Credit Agreement (including, without limitation, Section 7.13 of the Credit Agreement), and (ii) until an Event of Default has occurred and is continuing, the Debtor may sell or otherwise dispose of Collateral

-7-

to the extent not prohibited by the terms of the Credit Agreement (including, without limitation, Sections 7.13 and 7.14 of the Credit Agreement), and may grant liens on Collateral to the extent permitted by Sections 4.1 and/or 7.11 of the Credit Agreement, provided that a sale, lease or other disposition in the ordinary course of business shall not under any circumstance include a transfer, sale or lease in satisfaction, partial or complete, of a debt owing by such Debtor unless the debt so satisfied is secured with a lien on or ownership right in the goods in question which is prior to the security interest of the Agent therein and is a Permitted Encumbrance.

(d) Each Debtor shall at all times insure the Collateral consisting of tangible personal property against such risks and hazards as other persons or entities similarly situated insure against, and including in any event loss or damage by fire, theft, burglary, pilferage, loss in transit and such other hazards as the Agent may reasonably specify, in amounts and under policies containing lenders loss payable clauses to the Agent as its interest may appear (and, if the Agent requests, naming the Agent and the Secured Creditors as additional insureds therein) and by insurers reasonably acceptable to the Agent, it being agreed that the foregoing shall not preclude any Debtor from directly or indirectly self insuring risks as and to the extent prudent and customary for companies similarly situated and then to the extent permitted by the Credit Agreement. All premiums on such insurance shall be paid by the Debtors and, upon the Agent’s request, the policies of such insurance (or certificates therefor) shall be delivered by the Debtors to the Agent. All insurance required hereby shall provide to the extent commercially reasonably available that any loss shall be payable notwithstanding any act or negligence of the relevant Debtor, shall provide that no cancellation thereof shall be effective until at least 30 days after receipt by the relevant Debtor and the Agent of written notice thereof, and shall be reasonably satisfactory to the Agent in all other respects. Each Debtor may retain any proceeds of such insurance arising out of the loss, damage or destruction of the Collateral owned or leased by such Debtor so long as no Event of Default shall have occurred and be continuing or shall arise and be continuing after giving effect to such loss, damage or destruction. After the occurrence and during the continuance of any Event of Default, each Debtor will immediately pay over such proceeds of insurance to the Agent which shall thereafter be applied to the reduction of the Obligations (whether or not then due) or held as collateral security therefore, as the Agent may then determine. All insurance proceeds shall be subject to the lien and security interest of the Agent in the Collateral. Each Debtor hereby authorizes the Agent, at the Agent’s option, to adjust, compromise and settle any losses under any insurance afforded at any time after the occurrence and during the continuance of any Event of Default, and such Debtor does hereby irrevocably constitute the Agent, its officers, agents and attorneys, in such case as such Debtor’s attorneys-in-fact, with full power and authority to effect such adjustment, compromise and/or settlement and to endorse any drafts drawn by an insurer of the Collateral or any part thereof and to do everything necessary to carry out such purposes and to receive and receipt for any unearned premiums due under policies of such insurance.

(e) Each Debtor shall, at all reasonable times upon reasonable prior notice, allow the Agent, any Secured Creditor, and their respective representatives free access to and right of inspection of the Collateral during such Debtor’s normal business hours. Upon the occurrence and during the

-8-

continuance of any Event of Default, the Agent shall have the right to verify all or any part of the Collateral in any manner, and through any medium, which the Agent considers appropriate, and each Debtor agrees to furnish all assistance and information, and perform any acts, which the Agent may reasonably require in connection therewith.

(f) Each Debtor’s legal name and state of organization is correctly set forth in Schedule A attached hereto. No Debtor has transacted business at any time during the immediately preceding five‑year period, and does not currently transact business, under any other legal names or trade names other than the prior legal names and trade names (if any) set forth on Schedule B attached hereto. No Debtor shall change its legal name or transact business under any other trade name without first giving 15 days’ prior written notice of its intent to do so to the Agent.

(g) Schedule C attached hereto contains a true, complete, and current listing of all copyrights, copyright applications, trademarks, trademark rights, tradenames, patents, patent rights and licenses, patent applications and other intellectual property rights that are owned by the Debtors and are registered with any governmental authority. The relevant Debtor shall promptly notify the Agent in writing of any such additional intellectual property rights acquired or arising after the date hereof, and shall submit to the Agent a supplement to Schedule C attached hereto to reflect such additional rights (provided such Debtor’s failure to do so shall not impair the Agent’s security interest therein). The Debtors own or possess rights to use all franchises, licenses, copyrights, copyright applications, patents, patent rights and licenses, patent applications, trademarks, trademark rights, trade names, trade name rights, copyrights and rights with respect to the foregoing which are required to conduct their business. To the best of the Debtors’ knowledge, no event has occurred which permits, or after notice or lapse of time or both would permit, the revocation or termination of any such rights, and no Debtor is liable to any person for infringement under applicable law with respect to any such rights as a result of its business operations.

(h) Schedule E attached hereto contains a true, complete and current listing of all Commercial Tort Claims held or maintained by the Debtors as of the date hereof for an amount equal to or greater than $25,000,000, each described by reference to the specific incident giving rise to the applicable claim. Each Debtor agrees to execute and deliver to the Agent a supplement to this Agreement in the form attached hereto as Schedule F, or in such other form reasonably acceptable to the Agent, promptly upon becoming aware of any other Commercial Tort Claim in an amount equal to or greater than $25,000,000 held or maintained by any Debtor arising after the date hereof.

(i) Each Debtor agrees to execute and deliver to the Agent such further agreements, assignments, instruments and documents, and to do all such other things, as the Agent may reasonably deem necessary or appropriate to assure the lien and security interest of the Agent in the Collateral granted hereby, including, without limitation, (i) the execution and delivery of such financing statements and amendments thereof and supplements thereto or other instruments and documents as the Agent may from time to time reasonably require to comply with the UCC and any other applicable law, (ii) the execution and delivery of such patent, trademark and copyright assignment

-9-

agreements as the Agent may from time to time reasonably require to comply with the filing requirements of the United States Patent and Trademark Office and the United States Copyright Office, and (iii) the execution and delivery of and the use of commercially reasonable efforts to cause the relevant depository institutions, financial intermediaries and letter of credit issuers to execute and deliver such control agreements with respect to all Letter-of-Credit Rights and electronic Chattel Paper as the Agent may from time to time reasonably require in accordance with the terms hereof. Each Debtor hereby agrees that a carbon, photographic or other reproduction of this Agreement or any such financing statement is sufficient for filing as a financing statement by the Agent without notice thereof to such Debtor wherever the Agent in its sole discretion desires to file the same. Each Debtor hereby authorizes the Agent to file any and all financing statements covering the Collateral or any part thereof as the Agent may require, including financing statements describing the Collateral as “all assets” or “all personal property” or words of like meaning. The Agent may order lien searches from time to time against any Debtor and the Collateral, and the Debtors shall promptly reimburse the Agent for all reasonable costs and expenses incurred in connection with such lien searches; provided, however, that prior to the occurrence of any Event of Default the Debtors shall not have any obligation to reimburse the Agent for the reasonable costs and expenses of more than one lien search during any calendar year. In the event for any reason the law of any jurisdiction other than New York becomes or is applicable to the Collateral or any part thereof, or to any of the Obligations, each Debtor agrees to execute and deliver all such instruments and documents and to do all such other things as the Agent reasonably deems necessary or appropriate to preserve, protect and enforce the security interest of the Agent under the law of such other jurisdiction.

(j) Upon the occurrence and during the continuance of any Event of Default, on failure of any Debtor to perform any of its covenants and agreements herein contained, the Agent may at its option perform the same and in so doing may expend such sums as the Agent may reasonably deem advisable in the performance thereof, including, without limitation, (i) payment of any insurance premiums, (ii) payment of any taxes, liens and encumbrances, (iii) expenditures made in defending against any adverse claims, and (iv) all other expenditures which the Agent may be compelled to make by operation of law or which the Agent may make by agreement or otherwise for the protection of the Collateral. All such sums and amounts so expended shall be repayable by such Debtor immediately without notice or demand, shall constitute additional Obligations secured hereunder, and shall bear interest from the date said amounts are expended at the rate per annum (computed on the basis of a 360-day year for the actual number of days elapsed) equal to the sum of 2% plus the rate otherwise applicable to Domestic Rate Loans under the Revolving Facility in effect from time to time (such rate per annum as so determined being hereinafter referred to as the “Reimbursement Rate”). No such performance of any covenant or agreement by the Agent on behalf of any Debtor, and no such advancement or expenditure therefor, shall relieve any Debtor of any default under the terms of this Agreement or in any way obligate the Agent or any Secured Creditor to take any further or future action with respect thereto. The Agent is hereby authorized to charge any depository or other account of any Debtor maintained with the Agent for the amount of such sums and amounts so expended.

Section 4. Special Provisions Re: Receivables.

(a) So long as no Event of Default shall have occurred and be continuing, any merchandise or other goods which are returned by a customer or account debtor to any Debtor or are otherwise recovered by such Debtor, may be resold by such Debtor in the ordinary course of its business in accordance with Section 3(c) hereof; and after the occurrence and during the continuance of any Event of Default, at the request of the Agent, such merchandise and other goods shall be set aside and held by such Debtor as trustee for the Agent and the Secured Creditors and shall remain part of the Collateral. So long as no Event of Default shall have occurred and be continuing, each Debtor may settle and adjust disputes and claims with its customers and account debtors, handle returns and recoveries and grant discounts, credits and allowances, in each case in the ordinary course of its business and otherwise for amounts and on terms which such Debtor considers advisable. However, after the occurrence and during the continuance of any Event of Default, at the request of the Agent, each Debtor shall notify the Agent promptly of all returns and recoveries and shall deliver the merchandise or other returned goods to the Agent. After the occurrence and during the continuance of any Event of Default, at the request of the Agent each Debtor shall also notify the Agent promptly of all disputes and claims and settle or adjust them at no expense to the Agent or the Secured Creditors, but no discount, credit or allowance other than on normal trade terms in the ordinary course of business shall be granted to any customer or account debtor and no returns of merchandise or other goods shall be accepted by any Debtor without the Agent’s consent. The Agent may, at all times after the occurrence and during the continuance of any Event of Default, settle or adjust disputes and claims directly with customers or account debtors for amounts and upon terms which the Agent considers advisable.

(b) If any Receivable arises out of a contract with the United States of America or any of its departments, agencies or instrumentalities, upon the Agent’s request after the occurrence and during the continuance of an Event of Default, each Debtor agrees to so notify the Agent and execute whatever instruments and documents are reasonably required by the Agent in order that such Receivable shall be assigned to the Agent and that proper notice of such assignment shall be given under the federal Assignment of Claims Act (or any successor statute).

Section 5. Special Provisions Re: Instrument or Chattel Paper.

(a) To the extent any Pledged Note or other item of Collateral is evidenced by an Instrument or Chattel Paper, the applicable Debtor shall cause such Instrument or Chattel Paper to be pledged and delivered to the Agent; provided, however, that, unless (i) an Event of Default shall have occurred and be continuing and (ii) the Agent or the Required Lenders shall have otherwise required, a Debtor shall not be required to deliver any such Instrument or Chattel Paper if and only so long as (A) the fair market value of any such Instrument or Chattel Paper held by such Debtor is less than $5,000,000 and (B) the aggregate fair market value of all such Instruments or Chattel Paper held by the Borrowers, the Debtors and the other Guarantors and not delivered to the Agent under the Collateral Documents is less than $40,000,000 at any one time outstanding.

-11-

(b) To the extent required to be delivered under Section 5(a) above, the relevant Debtor shall endorse all Instruments and Chattel Paper or other item of Collateral in blank and deliver the same to the Agent in a form sufficient to transfer title thereto and shall also duly execute and deliver such other Instruments and Chattel Paper of transfer or assignment as to any other Collateral granted pursuant hereto, all in form and substance reasonably satisfactory to the Agent. To the extent required to be delivered under Section 5(a) above, the relevant Debtor shall deliver to the Agent true and correct copies of all Instruments and Chattel Paper and documents securing each item of Collateral or setting forth terms and conditions applicable thereto. After the occurrence and during the continuance of an Event of Default, upon request by the Agent, all tangible Chattel Paper and Instruments shall, unless delivered to the Agent or its agent, contain a legend reasonably acceptable to the Agent indicating that such Chattel Paper or Instrument is subject to the security interest of the Agent contemplated by this Agreement; provided, however, that unless the Agent or the Required Lenders shall have required otherwise, a Debtor shall not be required to so legend any such Instrument or Chattel Paper if and only so long as (i) the fair market value of any such Instrument or Chattel Paper held by such Debtor is less than $5,000,000 and (ii) the aggregate fair market value of all such Instruments or Chattel Paper held by the Borrowers, the Debtors and the other Guarantors and not delivered to the Agent under the Collateral Documents is less than $40,000,000 at any one time outstanding.

(c) After the occurrence and during the continuance of any Event of Default, no Debtor shall, without the prior written consent of the Agent, release any collateral or guarantors of the Instruments or Chattel Paper or amend, modify, waive or otherwise take any action which would materially impair the value or collectability of all or any part thereof. At the request of the Agent, each Debtor further agrees to promptly deliver to the Agent copies of all statements, reports and other information and data submitted by any obligor of an Instrument or Chattel Paper to such Debtor.

(d) Each Debtor hereby authorizes and directs each obligor of an Instrument or Chattel Paper, upon receipt of notice from the Agent that an Event of Default has occurred and is continuing, to make all distributions and payments now due or hereafter to become due to such Debtor in respect of such Instrument or Chattel Paper directly to the Agent, and such Debtor agrees that such payments or distributions to the Agent as aforesaid shall be a good receipt and acquittance to such Debtor to the extent so made.

Section 6. Special Provisions Re: Investment Property and Deposits.

(a) Unless and until an Event of Default has occurred and is continuing and thereafter until notified to the contrary by the Agent pursuant to Section 10(e) hereof:

(i) each Debtor shall be entitled to exercise all voting and/or consensual powers pertaining to the Investment Property or any part thereof owned or held by it, for all purposes not inconsistent with the terms of this Agreement, the Credit Agreement, or any other document evidencing or otherwise relating to any Obligations; and

(ii) each Debtor shall be entitled to receive and retain all cash dividends paid upon or in respect of the Investment Property owned or held by it.

-12-

(b) Except for equity interests in direct or indirect Subsidiaries, all Investment Property of each Debtor (including all securities, certificated or uncertificated, securities accounts, and commodity accounts but excluding any split-dollar insurance policies) having a fair market value of $5,000,000 or more maintained by such Debtor on the date hereof is listed and identified on Schedule D attached hereto. Each Debtor shall promptly notify the Agent of any other such Investment Property with a fair market value of $5,000,000 or more acquired or maintained by such Debtor after the date hereof, and shall submit to the Agent a supplement to Schedule D attached hereto to reflect such additional Investment Property (provided such Debtor’s failure to do so shall not impair the Agent’s security interest therein). Certificates for all certificated securities now or at any time constituting such Investment Property hereunder shall be promptly delivered by the relevant Debtor to the Agent duly endorsed in blank for transfer or accompanied by an appropriate assignment or assignments or an appropriate undated stock power or powers, in every case sufficient to transfer title thereto, and, with respect to any such uncertificated securities or any such Investment Property held by a securities issuer or intermediary, commodity issuer or intermediary, or other issuer or financial intermediary of any kind, the relevant Debtor shall execute and deliver, and shall cause any such issuer or intermediary to execute and deliver, an agreement among such Debtor, the Agent and such issuer or intermediary in form and substance satisfactory to the Agent which provides, among other things, for the issuer’s or intermediary’s agreement that it will comply with such entitlement orders, and apply any value distributed on account of any such Investment Property, as directed by the Agent without further consent by such Debtor at any time after the occurrence and during the continuance of any Event of Default; provided, however, that, unless (i) an Event of Default shall have occurred and be continuing and (ii) the Agent or the Required Lenders shall have otherwise required, a Debtor shall not be required to deliver any such certificates or cause any such agreement to be entered into with the relevant issuer or financial intermediary with respect to (A) Investment Property having a final maturity date not in excess of 90 days from the date the relevant Debtor obtains such Investment Property or (B) other Investment Property if and so long as (x) the fair market value of any such other Investment Property held by such Debtor is less than $5,000,000 and (y) the aggregate fair market value of all such other Investment Property held by the Borrowers, the Debtors and the other Guarantors and not subject to the control (as such term is defined in the UCC) of the Agent under the Collateral Documents is less than $40,000,000 at any one time outstanding. The Agent may at any time after the occurrence and during the continuance of an Event of Default cause to be transferred into its name or the name of its nominee or nominees any and all of the Investment Property hereunder.

(c) Unless and until an Event of Default has occurred and is continuing, each Debtor may sell or otherwise dispose of any Investment Property to the extent permitted by the Credit Agreement. During the existence of any Event of Default, no Debtor shall sell or otherwise dispose of all or any part of the Investment Property without the prior written consent of the Agent.

(d) Each Debtor represents that on the date of this Agreement, to the best of its knowledge, none of the Investment Property consists of margin stock (as such term is defined in Regulation U of the Board of Governors of the Federal Reserve System) except to the extent such Debtor has delivered to the Agent a duly executed and completed Form U‑1 with respect to such margin stock. If at any time the Investment Property or any part thereof consists of margin stock and the relevant Debtor has knowledge of the same, such Debtor shall promptly so notify the Agent and deliver to the Agent a duly executed and completed

-13-

Form U‑1 and such other instruments and documents as (i) are necessary to satisfy the applicable requirements of Regulations T, U and X of the Board of Governors of the Federal Reserve System with respect to such margin stock and (ii) are reasonably requested by the Agent in form and substance reasonably satisfactory to the Agent.

(e) Notwithstanding anything to the contrary contained herein, in the event any Investment Property is subject to the terms of a separate security agreement (including, without limitation, the Sixth Amended and Restated Pledge Agreement bearing even date herewith relating to the stock of certain of the Debtors hereunder) in favor of the Agent, the terms of such separate security agreement shall govern and control unless otherwise agreed to in writing by the Agent and the Secured Creditors.

Section 7. Collection of Receivables Instruments and Chattel Paper.

(a) Except as otherwise provided in this Agreement, each Debtor shall make collection of all Receivables, Instruments and Chattel Paper and may use the same to carry on its business in accordance with sound business practice and otherwise subject to the terms hereof.

(b) If any Event of Default has occurred and is continuing, in the event the Agent requests a Debtor to do so: (i) all Instruments and Chattel Paper at any time constituting part of the Collateral (including any postdated checks) shall, upon receipt by the relevant Debtor, be immediately endorsed to and deposited with Agent; and/or (ii) such Debtor shall instruct all customers and account debtors and any other obligor of any of the Collateral to remit all payments in respect of the Collateral to a lockbox or lockboxes under the sole custody and control of Agent and which are maintained at post offices selected by the Agent.

(c) If any Event of Default has occurred and is continuing, the Agent or its designee may notify each Debtor’s customers or account debtors or any other obligor at any time that the Collateral has been assigned to the Agent or that the Agent has a security interest therein, and either in its own name, or such Debtor’s name, or both, demand, collect (including, without limitation, through a lockbox analogous to that described in Section 7(b)(ii) hereof), receive, receipt for, ▇▇▇ for, compound and give acquittance for any or all amounts due or to become due on the Collateral, and in the Agent’s discretion file any claim or take any other action or proceeding which the Agent may deem reasonably necessary or appropriate to protect and realize upon the security interest of the Agent in the Collateral or any part thereof.

(d) Any proceeds of Collateral transmitted to or otherwise received by the Agent pursuant to any of the provisions of Sections 7(b) or 7(c) hereof may be handled and administered by the Agent in and through a remittance account or accounts maintained at the Agent or by the Agent at a commercial bank or banks selected by the Agent (each a “Depositary Bank”), and each Debtor acknowledges that the maintenance of such remittance accounts by the Agent is solely for the Agent’s convenience. The Agent need not apply or give credit for any item included in proceeds of Receivables, Instruments, Chattel Paper or other Collateral until the relevant Depositary Bank has received final payment therefor at its office in cash or final solvent credits current at the site of deposit acceptable to the Agent and the relevant Depositary Bank as such. However, if the Agent does permit credit to be given for any item prior to a Depositary Bank receiving final payment therefor and such Depositary Bank fails to receive such final payment or an item is charged back

-14-

to the Agent or any Depositary Bank for any reason, the Agent may at its election in either instance charge the amount of such item back against any such remittance account or any depository account of a Debtor maintained with the Agent. Each Debtor hereby indemnifies the Agent and the Secured Creditors from and against all liabilities, damages, losses, actions, claims, judgments, costs, expenses, charges and attorneys’ fees suffered or incurred by the Agent or any Secured Creditor because of the maintenance of the foregoing arrangements; provided, however, that no Debtor shall be required to indemnify the Agent or any Secured Creditor for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the person seeking to be indemnified. The Agent and the Secured Creditors shall have no liability or responsibility to any Debtor for the Agent or any other Depositary Bank accepting any check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement whatsoever or be responsible for determining the correctness of any remittance.

Section 8. Special Provisions Re: Inventory and Equipment.

(a) Each Debtor shall at its own cost and expense maintain, keep and preserve all material portions of the Inventory in good and merchantable condition and keep and preserve all material portions of the Equipment in good repair, working order and condition, ordinary wear and tear excepted, and, without limiting the foregoing, will from time to time make all necessary and proper repairs, replacements and additions to the Equipment so that the overall efficiency of the Equipment taken as a whole shall be fully preserved and maintained.

(b) Each Debtor warrants and agrees that no Inventory is or will be consigned to any other person or entity without the Agent’s prior written consent.

(c) At the Agent’s request, each Debtor shall at its own cost and expense cause the lien of the Agent in and to any portion of the Collateral subject to a certificate of title law to be duly noted on such certificate of title or to be otherwise filed in such manner as is prescribed by law in order to perfect such lien and will cause all such certificates of title and evidences of lien to be deposited with the Agent.

(d) In the event the Equipment, or any part thereof, is or may be attached to real estate in such a manner that the same may become a fixture, at the Agent’s request after the occurrence and during the continuance of an Event of Default, the relevant Debtor shall take all action reasonably requested by the Agent to maintain the lien and security interest of the Agent in such Collateral at all times fully perfected and in full force and effect, including, without limitation, such fixture financing statements as the Agent may require and, in the event any other person has any right, title or interest in, or lien upon, any such real estate, such Debtor shall use commercially reasonable efforts to cause such person to enter an agreement (i) pursuant to which such person disclaims any right, title and interest in, or lien on, such Equipment, (ii) which allows for the removal of such Equipment by the Agent and (iii) which is otherwise in form and substance reasonably satisfactory to the Agent.

-15-

(e) If any of the Inventory is at any time evidenced by a negotiable document of title, at the Agent’s request after the occurrence and during the continuance of an Event of Default, such document shall be promptly delivered by the relevant Debtor to the Agent.

Section 9. Power of Attorney. In addition to any other powers of attorney contained herein, each Debtor hereby appoints the Agent, its nominee, or any other person whom the Agent may designate as such Debtor’s attorney-in-fact, with full power after the occurrence and during the continuance of any Event of Default: (i) to sign such Debtor’s name on verifications of Receivables and other Collateral; (ii) to send requests for verification of Collateral to such Debtor’s customers, account debtors and other obligors; (iii) to endorse such Debtor’s name on any checks, notes, acceptances, money orders, drafts and any other forms of payment or security that may come into the Agent’s possession; (iv) to endorse the Collateral in blank or to the order of the Agent or its nominee; (v) to sign such Debtor’s name on any invoice or ▇▇▇▇ of lading relating to any Collateral, on claims to enforce collection of any Collateral, on notices to and drafts against customers and account debtors and other obligors, on schedules and assignments of Collateral, on notices of assignment and on public records; (vi) to notify the post office authorities to change the address for delivery of such Debtor’s mail to an address designated by the Agent; (vii) to receive and open all mail addressed to such Debtor; and (viii) to do all things necessary to carry out this Agreement. Each Debtor hereby ratifies and approves all acts of any such attorney and agrees that neither the Agent nor any such attorney will be liable for any acts or omissions nor for any error of judgment or mistake of fact or law other than such person’s gross negligence or willful misconduct. The Agent may file one or more financing statements disclosing its security interest in any or all of the Collateral without any Debtor’s signature appearing thereon. Each Debtor also hereby grants the Agent a power of attorney to execute any such financing statements, or amendments and supplements to financing statements, on behalf of such Debtor without prior notice thereof to any Debtor. The foregoing powers of attorney, being coupled with an interest, are irrevocable until the Obligations have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit to or for the account of the Borrowers have expired or otherwise been terminated (including Cash Collateralization of Letters of Credit).

Section 10. Defaults and Remedies.

(a) The occurrence of any event or the existence of any condition specified as an “Event of Default” under the Credit Agreement shall constitute an “Event of Default” hereunder.

(b) During the existence of any Event of Default, the Agent shall have, in addition to all other rights provided herein or by law, the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights or remedies are asserted and regardless of whether the UCC applies to the affected Collateral), and further the Agent may, without demand and without advertisement, notice, hearing or process of law to the extent permitted by law, all of which each Debtor hereby waives to the extent permitted by law, at any time or times, sell and deliver any or all Collateral held by or for it at public or private sale, at any securities exchange or broker’s board or at any of the Agent’s offices or elsewhere, for cash, upon credit or otherwise, at such prices and upon such terms as the Agent deems advisable, in its sole discretion. Also, if less than all the Collateral is sold, the Agent shall have no

-16-

duty to ▇▇▇▇▇▇▇▇ or apportion the part of the Collateral sold as between the Debtors, or any of them, but may sell and deliver any or all of the Collateral without regard to which of the Debtors are the owners thereof. In the exercise of any such remedies, the Agent may sell all the Collateral as a unit even though the sales price thereof may be in excess of the amount remaining unpaid on the Obligations. The Agent is authorized at any sale or other disposition of the Collateral or any part thereof, if it deems it advisable so to do, to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing for their own account for investment, and not with a view to the distribution or resale of any of the Collateral. In addition to all other sums due the Agent or any Secured Creditor hereunder, each Debtor shall pay the Agent and the Secured Creditors all reasonable costs and expenses incurred by the Agent and such Secured Creditors, including reasonable attorneys’ fees and court costs, in obtaining, liquidating or enforcing payment of Collateral or the Obligations or in the prosecution or defense of any action or proceeding by or against the Agent, such Secured Creditor or any Debtor concerning any matter arising out of or connected with this Agreement or the Collateral or the Obligations, including, without limitation, any of the foregoing arising in, arising under or related to a case under the United States Bankruptcy Code (or any successor statute). Any requirement of reasonable notice shall be met if such notice is personally served on or mailed, postage prepaid, to the Debtors in accordance with Section 16(b) hereof at least 10 days before the time of sale or other event giving rise to the requirement of such notice; provided however, that during the existence of any Event of Default, no notification need be given to a Debtor if such Debtor has signed, after the occurrence of such Event of Default, a statement renouncing any right to notification of sale or other intended disposition. The Agent shall not be obligated to make any sale or other disposition of the Collateral regardless of notice having been given. The Agent or any Secured Creditor may be the purchaser at any such sale. Each Debtor hereby waives to the extent permitted by law all of its rights of redemption from any such sale. The Agent may postpone or cause the postponement of the sale of all or any portion of the Collateral by announcement at the time and place of such sale, and such sale may, without further notice, be made at the time and place to which the sale was postponed or the Agent may further postpone such sale by announcement made at such time and place. The Agent has no obligation to prepare the Collateral for sale. The Agent may sell or otherwise dispose of the Collateral without giving any warranties as to the Collateral or any part thereof, including disclaimers of any warranties of title or the like, and each Debtor acknowledges and agrees that the absence of such warranties shall not render the disposition commercially unreasonable.

(c) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, the Agent shall have the right, in addition to all other rights provided herein or by law, to take physical possession of any and all of the Collateral and anything found therein, the right for that purpose to enter without legal process any premises where the Collateral may be found (provided such entry be done lawfully), and the right to maintain such possession on each Debtor’s premises (the Debtors hereby agreeing to lease such premises without cost or expense to the Agent or its designee if the Agent so requests) or to remove the Collateral or any part thereof to such other places as the Agent may desire. If any Event of Default has occurred and is continuing, the Agent shall have the right to exercise any and all rights with respect to all Deposit Accounts of each Debtor, the right to direct the disposition of the funds in each Deposit Account and to collect, withdraw and receive all amounts due or to become due or payable under each such Deposit Account. If any Event of Default has occurred and is continuing, each Debtor shall, upon the Agent’s demand, assemble the Collateral and make it available to the Agent at a place designated by the Agent. If

-17-

the Agent exercises its right to take possession of the Collateral, each Debtor shall also at its expense perform any and all other steps requested by the Agent to preserve and protect the security interest hereby granted in the Collateral, such as placing and maintaining signs indicating the security interest of the Agent, appointing overseers for the Collateral and maintaining Collateral records.

(d) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, each Debtor hereby grants to the Agent and the Secured Creditors a royalty-free irrevocable license and right to use all of such Debtor’s patents, patent applications, patent licenses, trademarks, trademark registrations, trademark licenses, trade names, trade styles, and similar intangibles in connection with any foreclosure or other realization by the Agent or the Secured Creditors on all or any part of the Collateral, provided that the license granted hereunder shall not include any rights in any license agreement under which the relevant Debtor is licensee which, by its terms, prohibits the license contemplated by this Section 10(d). The license and right granted the Agent and the Secured Creditors hereby shall be without any royalty or fee or charge whatsoever.

(e) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, all rights of a Debtor to exercise the voting and/or consensual powers which it is entitled to exercise pursuant to Section 6(a)(i) hereof and/or to receive and retain the distributions which it is entitled to receive and retain pursuant to Section 6(a)(ii) hereof, shall, at the option of the Agent, cease and thereupon become vested in the Agent, which, in addition to all other rights provided herein or by law, shall then be entitled solely and exclusively to exercise all voting and other consensual powers pertaining to the Investment Property (including, without limitation, the right to deliver notice of control with respect to any Investment Property held in a securities account or commodity account and deliver all entitlement orders with respect thereto) and/or to receive and retain the distributions which such Debtor would otherwise have been authorized to retain pursuant to Section 6(a)(ii) hereof and shall then be entitled solely and exclusively to exercise any and all rights of conversion, exchange or subscription or any other rights, privileges or options pertaining to any Investment Property as if the Agent were the absolute owner thereof including, without limitation, the rights to exchange, at its discretion, any and all of the Investment Property upon the merger, consolidation, reorganization, recapitalization or other readjustment of the respective issuer thereof or upon the exercise by or on behalf of any such issuer or the Agent of any right, privilege or option pertaining to any Investment Property and, in connection therewith, to deposit and deliver any and all of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Agent may determine. In the event any of the Collateral shall constitute restricted securities within the meaning of any applicable securities laws, any disposition thereof in compliance with such laws shall not render the disposition commercially unreasonable.

(f) The powers conferred upon the Agent hereunder are solely to protect its interest in the Collateral and shall not impose on it any duty to exercise such powers. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control if such Collateral is accorded treatment substantially equivalent to that which the Agent accords its own property, consisting of similar type assets, it being understood, however, that the Agent shall have no responsibility for ascertaining or taking any action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating

-18-

to any such Collateral, whether or not the Agent has or is deemed to have knowledge of such matters. This Agreement constitutes an assignment of rights only and not an assignment of any duties or obligations of the Debtors in any way related to the Collateral, and the Agent shall have no duty or obligation to discharge any such duty or obligation. The Agent shall have no responsibility for taking any necessary steps to preserve rights against any parties with respect to any Collateral or initiating any action to protect the Collateral against the possibility of a decline in market value. Neither the Agent nor any party acting as attorney for the Agent shall be liable for any acts or omissions or for any error of judgment or mistake of fact or law other than their gross negligence or willful misconduct, as determined by a non‑appealable court of competent jurisdiction.

(g) Failure by the Agent to exercise any right, remedy or option under this Agreement or any other agreement between any Debtor and the Agent or provided by law, or delay by the Agent in exercising the same, shall not operate as a waiver; and no waiver shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and then only to the extent specifically stated. Neither the Agent or any Secured Creditor, nor any party acting as attorney for the Agent or any Secured Creditor, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than such person’s gross negligence or willful misconduct, as determined by a non‑appealable court of competent jurisdiction. The rights and remedies of the Agent and the Secured Creditors under this Agreement shall be cumulative and not exclusive of any other right or remedy which the Agent or the Secured Creditors may have. For purposes of this Agreement, an Event of Default shall be construed as continuing after its occurrence until the same is waived or cured in writing by the Required Lenders in accordance with the Credit Agreement.

Section 11. Application of Proceeds. The proceeds and avails of the Collateral at any time received by the Agent during the existence of any Event of Default hereunder shall, when received by the Agent in cash or its equivalent, be applied by the Agent in reduction of, or as collateral security for, the Obligations in accordance with the terms of the Credit Agreement. Each Debtor shall remain liable to the Agent and the Secured Creditors for any deficiency. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Debtors or to whomsoever the Agent reasonably determines is lawfully entitled thereto.

Section 12. Continuing Agreement. This Agreement shall be a continuing agreement in every respect and shall remain in full force and effect until all of the Obligations, both for principal and interest, have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit or otherwise make financial accommodations available to the Borrowers under the Credit Agreement have expired or otherwise been terminated (including Cash Collateralization of Letters of Credit). Upon each such termination of this Agreement, the Agent shall, upon the request and at the expense of the Debtors, forthwith release its security interest hereunder.

Section 13. Primary Security; Obligations Absolute. The lien and security herein created and provided for stand as direct and primary security for the Obligations. No application of any sums received by the Agent in respect of the Collateral or any disposition thereof to the reduction of the Obligations or any

-19-

portion thereof shall in any manner entitle any Debtor to any right, title or interest in or to the Obligations or any collateral security therefor, whether by subrogation or otherwise, unless and until all Obligations have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit or otherwise make financial accommodations available to the Borrowers, or any one of them, under the Credit Agreement have expired or otherwise have been terminated (including Cash Collateralization of Letters of Credit). Each Debtor acknowledges and agrees that the lien and security hereby created and provided for are absolute and unconditional and shall not in any manner be affected or impaired by any acts or omissions whatsoever of the Agent, any Secured Creditor or any other holder of any of the Obligations, and without limiting the generality of the foregoing, the lien and security hereof shall not be impaired by any acceptance by the Agent, any Secured Creditor or any holder of any of the Obligations of any other security for or guarantors upon any of the Obligations or by any failure, neglect or omission on the part of the Agent, any Secured Creditor or any other holder of any of the Obligations to realize upon or protect any of the Obligations or any collateral security therefor. The lien and security hereof shall not in any manner be impaired or affected by (and the Agent and the Secured Creditors, without notice to anyone, are hereby authorized to make from time to time) any sale, pledge, surrender, compromise, settlement, release, renewal, extension, indulgence, alteration, substitution, exchange, change in, modification or disposition of any of the Obligations, or of any collateral security therefor, or of any guaranty thereof or of any obligor thereon. The Secured Creditors may at their discretion at any time grant credit to the Borrowers, or any of them individually, without notice to any Debtor in such amounts and on such terms as the Secured Creditors may elect without in any manner impairing the lien and security hereby created and provided for. No release, compromise or discharge of any Debtor hereunder or with respect to any of the Obligations or any Collateral provided by such Debtor shall release or discharge, or impair the agreements of, any other Debtor hereunder or in any manner impair the liens and security interests granted by any other Debtor hereunder; and the Agent may proceed against the Collateral provided hereunder by any one or more of the Debtors without proceeding against the other Debtors, their respective properties or any other security or guaranty whatsoever. Without limiting the generality of the foregoing, the requisite number of Secured Creditors (as determined in accordance with the terms of the Credit Agreement) may at any time or from time to time release any Debtor from its obligations hereunder or release any Collateral or effect any compromise with any Debtor, and no such release or compromise shall in any manner impair or otherwise effect the liens granted by, or the obligations of, the other Debtors hereunder. In order to foreclose or otherwise realize hereon and to exercise the rights granted the Agent hereunder and under applicable law, there shall be no obligation on the part of the Agent, any Secured Creditor or any other holder of any of the Obligations at any time to first resort for payment to any Borrower or any other obligor on any of the Obligations or to any guaranty of the Obligations or any portion thereof or to resort to any other collateral security, property, liens or any other rights or remedies whatsoever, and the Agent shall have the right to enforce this instrument irrespective of whether or not other proceedings or steps are pending seeking resort to or realization upon or from any of the foregoing.

Section 14. The Agent. In acting under or by virtue of this Agreement, the Agent shall be entitled to all the rights, authority, privileges and immunities provided in the Credit Agreement, all of which provisions of the Credit Agreement (including, without limitation, Section 10 of the Credit Agreement) are incorporated by reference herein with the same force and effect as if set forth herein in their entirety. The Agent hereby

-20-

disclaims any representation or warranty to the Secured Creditors concerning the perfection of the security interest granted hereunder or in the value of any of the Collateral.

SECTION 15. PERSONAL JURISDICTION.

(a) EXCLUSIVE JURISDICTION. EXCEPT AS PROVIDED IN SECTION 15(b), THE AGENT, THE SECURED CREDITORS AND THE DEBTORS AGREE THAT ALL DISPUTES AMONG THEM ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN NEW YORK COUNTY, NEW YORK, BUT EACH OF THE AGENT, THE SECURED CREDITORS AND THE DEBTORS ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF NEW YORK COUNTY, NEW YORK. EACH OF THE DEBTORS WAIVES IN ALL DISPUTES ANY OBJECTION THAT SUCH DEBTOR MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE OR ANY OBJECTION THAT SUCH DEBTOR MAY HAVE THAT ANY OTHER PARTY HAS NOT BEEN JOINED IN SUCH PROCEEDING.

(b) OTHER JURISDICTIONS. EACH OF THE DEBTORS AGREES THAT THE AGENT AND THE SECURED CREDITORS SHALL HAVE THE RIGHT TO PROCEED AGAINST EACH OF THE DEBTORS OR THEIR COLLATERAL IN A COURT IN ANY LOCATION TO ENABLE THE AGENT OR ANY SECURED CREDITOR TO REALIZE ON THE COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE AGENT OR ANY SECURED CREDITOR, WHETHER OR NOT PROCEEDING SEPARATELY AGAINST ANY DEBTOR AND ITS PROPERTY OR JOINTLY AGAINST ANY BORROWER AND ANY ONE OR MORE OF THE DEBTORS AND THEIR PROPERTY. EACH OF THE DEBTORS AGREES THAT IT WILL NOT ASSERT ANY PERMISSIVE COUNTERCLAIMS IN ANY PROCEEDING BROUGHT IN ACCORDANCE WITH THIS PROVISION BY THE AGENT OR ANY SECURED CREDITOR TO REALIZE ON COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE AGENT OR ANY SECURED CREDITOR. EACH OF THE DEBTORS WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE AGENT OR ANY SECURED CREDITOR HAS COMMENCED A PROCEEDING DESCRIBED IN THIS SUBSECTION.

Section 16. Miscellaneous.

(a) This Agreement cannot be changed or terminated orally. This Agreement shall create a continuing lien on and security interest in the Collateral to the extent set forth herein and shall be binding upon each Debtor and its successors and assigns and shall inure, together with the rights and remedies of the Agent and the Secured Creditors hereunder, to the benefit of the Agent, the Secured Creditors and their successors and assigns; provided, however, that no Debtor may assign its rights or delegate its duties hereunder without the prior written consent of the Agent and the Secured Creditors. Without limiting the generality of the foregoing, and subject to the provisions of the Credit Agreement any Secured Creditor as a lender may

-21-

assign or otherwise transfer any indebtedness held by it secured by this Agreement to any other person or entity, and such other person or entity shall thereupon become vested with all the benefits in respect thereof granted to such Secured Creditor herein or otherwise.

(b) Except as otherwise specified herein, all notices hereunder shall be in writing (including, without limitation, notice by telecopy) and shall be given to the relevant party, and shall be deemed to have been made when given to the relevant party, in accordance with Section 11.9 of the Credit Agreement. All notices to the Debtors hereunder shall be made to the Company, as their agent, in accordance with Section 11.9 of the Credit Agreement.

(c) No Secured Creditor shall have the right to institute any suit, action or proceeding in equity or at law for the foreclosure or other realization upon any Collateral subject to this Agreement or for the execution of any trust or power hereof or for the appointment of a receiver, or for the enforcement of any other remedy under or upon this Agreement; it being understood and intended that no one or more of the Secured Creditors shall have any right in any manner whatsoever to affect, disturb or prejudice the lien and security interest of this Agreement by its or their action or to enforce any right hereunder, and that all proceedings at law or in equity shall be instituted, had and maintained by the Agent in the manner herein provided for the benefit of the Secured Creditors.

(d) In the event that any provision hereof shall be deemed to be invalid or unenforceable by reason of the operation of any law or by reason of the interpretation placed thereon by any court, this Agreement shall be construed as not containing such provision, but only as to such jurisdictions where such law or interpretation is operative, and the invalidity or unenforceability of such provision shall not affect the validity of any remaining provisions hereof, and any and all other provisions hereof which are otherwise lawful and valid shall remain in full force and effect.

(e) This Agreement shall be deemed to have been made in the State of New York and shall be governed by, and construed in accordance with, the laws of the State of New York (including Section 5‑1401 and Section 5‑1402 of the General Obligations law of the State of New York) without regard to principles of conflicts of law. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning of any provision hereof.

(f) This Agreement constitutes an assignment of rights only and not an assignment of any duties or obligations of any Debtor in any way related to the Collateral and that the Agent and the Secured Creditors shall have no duty or obligation to perform or discharge any such duty or obligation.

(g) In the event the Secured Creditors shall at any time in their discretion permit a substitution of Debtors hereunder or a party shall wish to become Debtor hereunder, such substituted or additional Debtor shall, upon executing an agreement in the form attached hereto as Schedule G, become a party hereto and be bound by all the terms and conditions hereof to the same extent as though such Debtor had originally executed this Agreement and in the case of a substitution, in lieu of the Debtor being replaced. No such substitution shall be effective absent the written consent of the Secured Creditors nor shall it in any manner affect the obligations of the other Debtors hereunder.
