ARTICLE 2. CREDIT FACILITIES.

2.1 Revolving Line of Credit.

(a) Advances and Letters of Credit. Subject to and upon the provisions of this Agreement and relying upon the representations and warranties herein set forth, the Lender agrees at any time and from time to time to make Advances to the Borrowers and issue Letters of Credit for the account of the Borrowers from the date hereof until the earlier of the Revolving Loan Ending Date or the date on which this Revolving Loan is terminated pursuant to Section 7 hereof, in an aggregate principal amount at any time outstanding not to exceed the Allowed Amount of Revolving Advances; provided however, that in no event shall the total Letter of Credit Exposure exceed $2,000,000.

In no event shall the Lender be obligated to make an Advance or issue a Letter of Credit hereunder if a Default shall have occurred and be continuing. Unless sooner terminated pursuant to other provisions of this Agreement, this Revolving Loan and the obligation of the Lender to make Advances and issue Letters of Credit hereunder shall automatically terminate on the Revolving Loan Ending Date without further action by, or notice of any kind from, the Lender. Within the limitations set forth herein and subject to the provisions of this Agreement, the Borrowers may borrow, repay and reborrow under this Revolving Loan. The fact that there may be no Advances or Letters of Credit outstanding at any particular time shall not affect the continuing validity of this Agreement.

(b) Deposit of Advances. Each Advance will be advanced by the Lender not later than the Business Day following the day (which shall be a Business Day) of the Borrowers’ request therefor. The proceeds of each Advances will be deposited by the Lender in the Borrowers’ Operating Account with the Lender.

(c) Liability of Lender. Lender shall in no event be responsible or liable to any person other than Borrowers for the disbursement of or failure to disburse Advances or any part thereof, and no other party shall have any right or claim against Lender under this Agreement or the other Financing Documents.

(d) Mandatory Prepayments. If the principal outstanding under the

ESSEX – Amended and Restated Credit Agreement 19

Revolving Loan plus the outstanding Letter of Credit Exposure, at any time exceeds the Allowed Amount, then Borrowers shall make an immediate payment of principal under the Revolving Loan in an amount sufficient that the principal outstanding under the Revolving Loan plus the outstanding Letter of Credit Exposure will no longer exceed the Allowed Amount.

(e) Procedure for Advances. Unless Borrowers have previously entered into a separate auto borrow or similar cash management service with Lender, Borrowers may request Advances by telephone through its employees or agents, as hereinafter provided. Each Advance request must be received by Lender not later than 1:00 p.m. (Eastern Standard time) on the date the Advance is to be made and must specify the amount of the Advance. Lender shall deposit the Advance into Borrowers’ Operating Account if Borrowers are entitled to the Advance, subject to the terms and conditions of this Agreement. If Borrowers have entered into a separate auto borrow or similar cash management service with Lender, then the provisions of such service shall control with respect to the procedures for making Advances to Borrowers. Lender shall have the right to terminate such auto borrow or similar cash management service at any time, as determined in Lender’s sole and absolute discretion.

Notwithstanding anything contained herein to the contrary, so long as the Borrowers opt to use the Lender’s “AutoBorrow” program and have executed and delivered to the Lender an AutoBorrow Service Agreement (which AutoBorrow Service Agreement remains in full force and effect), all Advances to be made hereunder shall be made in accordance with, and all interest accrued on such Advances and all repayments of such Advances shall be payable at the times and in the manner provided for in the AutoBorrow Service Agreement. To the extent that any of the provisions hereof are inconsistent with provisions of the AutoBorrow Service Agreement, the provisions of the AutoBorrow Service Agreement shall govern. Any Advances made to the Borrowers under the AutoBorrow Service Agreement shall nonetheless be deemed to be an Advance hereunder, subject to all other terms hereof.

(f) Interest on and Repayment of Revolving Loan; Auto Debit. Except for any period during which an Event of Default shall have occurred and be continuing, the Borrowers shall pay interest (calculated on a daily basis) on the unpaid principal balance of the Advances until maturity (whether by acceleration, extension or otherwise) at a per annum rate of interest equal at all times to the Libor-Based Rate in effect from time to time. After maturity, or during any period in which an Event of Default exists and remains continuing, the unpaid principal balance of the Advances shall bear interest at a rate equal to the Default Rate. Until the maturity of the Revolving Loan, all accrued and unpaid interest on all Advances shall be paid monthly on the first day of each month (each, an “Interest Payment Date”).

ESSEX – Amended and Restated Credit Agreement 20

Notwithstanding any other provision of this Agreement, if the Lender determines (which determination shall be conclusive) (i) that any applicable law, rule, or regulation, or any change in the interpretation of any such law, rule, or regulation shall make it unlawful or impossible for the Lender to charge or collect interest at the Libor-Based Rate, or (ii) that quotations of interest rates for the relevant deposits referred to in the definition of the Libor-Based Rate are not being provided in the relevant amounts or for the relevant maturities, then upon notice from the Lender to the Borrowers, the entire outstanding principal balance of the Revolving Loan shall bear interest at the Prime-Based Rate.

If not sooner paid, the entire outstanding principal balance of the Advances, together with all accrued and unpaid interest thereon, shall be due and payable on the Revolving Loan Ending Date.

(g) Use of Revolving Loan Proceeds. The proceeds of the Revolving Loan shall be used for working capital, to finance Permitted Acquisitions, and for general corporate purposes not inconsistent with this Agreement.

(h) Revolving Loan Fees. Borrowers jointly and severally promise to pay Lender the following fees in consideration of entering into this Agreement. These fees are in addition to interest payable under the Revolving Note:

a. During the period from the date hereof until the earlier of the Revolving Loan Ending Date or the date on which the Revolving Loan is terminated pursuant to the provisions hereof, the Borrowers shall pay to the Lender an availability fee in a per annum amount equal to the Unused Commitment Fee Percentage times the average daily unused portion of the Maximum Revolving Credit Commitment. Such availability fee shall commence to accrue on the date hereof and shall be due and payable by the Borrowers quarterly, in arrears, commencing on September 30, 2005, and, on the last Business Day of each third month thereafter, and on the earlier of the Revolving Loan Ending Date or on the date on which the Revolving Loan is terminated pursuant to the terms hereof.

b. Lender shall have the right to perform field examinations at any time, in its sole discretion. Borrowers shall pay to Lender, on demand, the fees and costs associated with a field examination performed prior to the closing of the Credit Facilities and for one field examination to be performed each calendar year provided, however, that the Lender does not intend to perform a field examination in the first year following closing unless the Borrowers close an acquisition exceeding $5,000,000 during such time, and with respect to which the Original Borrowers shall be excluded. Any additional field examinations will be at Lender’s own expense if no Event of Default has occurred and remains uncured at the time of the additional field examination, but shall be at the Borrowers’ expense if an Event of Default has occurred and remains uncured at the time of the additional field examination.

ESSEX – Amended and Restated Credit Agreement 21

(i) Voluntary Prepayments. Within the limitations set forth herein and subject to the provisions of this Agreement, the Borrowers may prepay any Advance in whole or in part, from time to time without premium or penalty. Any permitted prepayment need not be accompanied by payment of interest on the amount prepaid except, that any prepayment of Advances which constitutes a final payment of all Advances shall be accompanied by payment of all interest thereon accrued through the date of prepayment.

(j) Terms of Letters of Credit.

All powers, right, remedies and provisions set forth in any Letter of Credit Agreement shall be in addition to those set forth herein. In the event of any conflict between the provisions of this Agreement and the provisions of any Letter of Credit Agreement, the provisions of this Agreement shall prevail and control unless expressly provided otherwise herein or in the Letter of Credit Agreement.

(k) Procedures for Letters of Credit. The Borrowers shall give the Lender written notice of its request for a Letter of Credit at least three (3) Business Days prior to the date on which the Letter of Credit is to be opened by delivering to the Lender a duly executed Letter of Credit Agreement in form and content acceptable to the Lender setting forth (i) the face amount of the Letter of Credit, (ii) the name and address of the beneficiary of the Letter of Credit, (iii) whether the Letter of Credit is irrevocable or revocable, (iv) whether the Letter of Credit requested is a standby or commercial Letter of Credit, (v) the date the Letter of Credit is to be opened and the date the Letter of Credit is to expire, (vi) the purpose of the Letter of Credit, (vii) the terms and conditions for any draws under the Letter of Credit, and (viii) such other information as the Lender may reasonably deem to be necessary or desirable.

(l) Letter of Credit Fees. With respect to each Letter of Credit issued hereunder, the Borrowers shall pay to the Lender a letter of credit fee (the “Letter of Credit Fee”) set forth in the table attached hereto as Attachment I, payable in advance on or before the date of issuance and on each anniversary thereof plus the Lender’s then standard fee for the issuance, negotiation, processing and administration of letters of credit of the same type as the Letter of Credit. The amount of the Letter of Credit Fee

ESSEX – Amended and Restated Credit Agreement 22

payable on any date shall be a percentage of the face amount of such Letter of Credit, calculated on the basis of the table included as Attachment I hereto, based upon the Borrowers’ ratio of Total Funded Debt to EBTIDA as of the end of the immediately preceding calendar quarter.

(m) Agreement to Pay Letter of Credit Obligations. The Borrowers shall pay to the Lender the Letter of Credit Obligations when due; provided, however, that so long as the Borrowers have availability under the Revolving Loan, the Lender may, and is hereby authorized to, make Advances to itself to pay when due any or all Letter of Credit Obligations incurred in connection with Letters of Credit. The Lender may maintain on its books a letter of credit account (the “Letter of Credit Account”) with respect to the Letter of Credit Obligations paid and payable from time to time hereunder. Except for demonstrable error, the Letter of Credit Account shall be conclusive as to all amounts owing by the Borrowers to the Lender in connection with and on account of the Letter of Credit Obligations. From the date due until paid in full, all Letter of Credit Obligations shall bear interest at the Default Rate.

(n) Agreement to Pay Absolute. The obligation of the Borrowers to pay Letter of Credit Obligations set forth above shall be absolute and unconditional and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, (ii) the existence of any claim, setoff, defense or other right which the Borrowers may at any time have against the beneficiary under any Letter of Credit or the Lender, (iii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue provided that payment by the Lender under such Letter of Credit against presentation of such draft shall not have constituted gross negligence or willful misconduct, and (v) any other events or circumstances whatsoever, whether or not similar to any of the foregoing provided that the payment by the Lender under the Letter of Credit shall not have constituted gross negligence or willful misconduct of the Lender.

2.2 Guidance Line Facility. Subject to the terms and conditions of this Agreement (including, without limitation, all of the conditions precedent to the making of Advances set forth herein), from the date hereof until the earlier of the Revolving Loan Ending Date or the date on which this facility is otherwise terminated pursuant to the provisions of Section 7, the Lender may, in its sole and absolute discretion, from time to time make Advances to the Borrowers in an amount greater than the difference between the then-current Maximum Revolving Credit Commitment and the then-current Revolving Credit Exposure (each such Advance being hereinafter called a “Guidance Line Advance”); provided, however, that (a) the aggregate principal amount of all Guidance Line Advances shall not exceed $20,000,000, and (b) in no event shall the Lender make a new Guidance Line Advance hereunder if an Event of Default shall have occurred and be continuing. Once a Guidance Line Advance has been made

ESSEX – Amended and Restated Credit Agreement 23

hereunder, it shall be considered an Advance for all purposes under this Agreement (including, without limitation the calculation of the Revolving Credit Exposure) and shall be repaid in accordance with the terms and conditions hereof. Each time the Lender makes a Guidance Line Advance, the Maximum Revolving Credit Commitment shall automatically be increased to an amount equal to the Revolving Credit Exposure (after giving effect to such Guidance Line Advance).

Such 15-day period shall not be construed in any way to extend the due date of any such payment. Late charges are imposed for the purpose of defraying the Lender’s expenses incident to the handling of delinquent payments, and are in addition to, and not in lieu of, the exercise by the Lender of any rights and remedies hereunder or under applicable laws and any fees and expenses of any agents or attorneys which the Lender may employ upon the occurrence of an Event of Default.

(c) Payments. Whenever any payment to be made by the Borrowers under the provisions of this Agreement, the Notes or the Letter of Credit Agreements is due on a day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, in the case of any payment which bears interest, such extension of time shall be included in computing interest on such payment.

If necessary, Borrowers immediately will xxxx all books and records with an entry showing the absolute assignment of and granting of a security interest in all Collateral (other than classified Government Contracts) to Lender, and hereby grants the Lender the right to audit the books and records of Borrowers relating to Collateral at any time and from time to time. Borrowers shall (with respect to non-classified Collateral) (i) promptly furnish the Lender with any information with respect to Collateral requested by Lender; (ii) allow the Lender or its representatives to inspect the Collateral, at any time and wherever located and in whomever’s possession the Collateral may be, and to inspect and copy, or furnish the Lender or its representatives with copies of all records relating to the Collateral; (iii) furnish the Lender or its representatives such information as the Lender may request to identify the Collateral, at the time and in the form requested by Lender; and (iv) deliver upon request to Lender shipping and delivery receipts evidencing the shipment of goods and invoices evidencing the receipt of the Collateral and payment for the Collateral.

4.6 No Release. No injury to the Collateral, loss or destruction of the Collateral, failure to perfect or to continue the perfection of Lender’s security interest in the Collateral, or release of Lender’s security interest in the Collateral, or any part of it, shall relieve Borrowers of any obligation under this Agreement or under any of the other Loan Documents. Borrowers expressly waive all defenses based on suretyship or impairment of collateral, and shall not be released or discharged of any obligation under the Loan Documents, in whole or in part, by Lender’s failure to protect or preserve the Collateral provided, that such waiver shall not apply to any loss resulting

ESSEX – Amended and Restated Credit Agreement 30

from Lender’s gross negligence or willful misconduct.. No Person, in deciding to enter into this Loan Agreement, has relied on the execution of this Loan Agreement or the granting of a security interest in Collateral by any other Person. Each waives notice of any change in financial condition of any Person liable for the Credit Facilities or any part thereof, and agrees that maturity of the Credit Facilities or any part thereof may be accelerated, extended or renewed one or more times by Lender in its discretion, without notice to the Person and without affecting Lender’s security interest in the Collateral. Lender shall not be required to bring any action against any other Person or to resort to any other security or to any balance of any deposit account as a condition of enforcing its rights against any of the Collateral.

4.7 Assignment of Payments Under Certain Government Contracts and Government Accounts. On the Closing Date, and thereafter upon the creation of any Government Contract or Government Account other than classified accounts, Borrowers shall, at Lender’s option, execute and deliver to the Lender specific Assignments of Payments due or to become due with respect to any Government Account designated by Lender. Borrowers shall execute and deliver any and all documents and take any and all steps necessary to provide the Lender with an Assignment. The separate Assignment to the Lender of a right to payment under specific Government Contracts, as contemplated under this Section, shall not be deemed to limit the Lender’s security interest to Payments under those particular Government Contracts and the related Government Accounts, but rather the Lender’s security interest, as stated above, shall extend to Payments under any and all Government Contracts and the related Government Accounts and proceeds thereof, now or hereafter owned or acquired by any or all of the Borrowers. Anything in the foregoing notwithstanding, at its sole option, the Lender may exclude from this requirement, contracts of less than $500,000 in remaining value or contracts of less than six months in remaining duration and that such exclusion, if granted, will not release the Borrowers from the requirement to provide such assignments at such time in the future, as the Lender desires.

4.8 Additional Remedy for Failure to Assign Payments. Borrowers acknowledge that the Lender will be irreparably harmed if Borrowers fail to assign Payments due or to become due under any Government Contract when required by this Agreement, and that the Lender shall have no adequate remedy at law. Therefore, the Borrowers agree that the Lender shall be entitled to the following remedies, in addition to all other remedies allowed by law or under this Agreement,

a. an injunction compelling Borrowers’ compliance with the provisions of this Agreement requiring the Borrowers to assign Payments due or to become due under any Government Contract; and

ESSEX – Amended and Restated Credit Agreement 31

b. such other or further equitable relief as may be necessary or desirable to secure to Lender the benefits of the rights of an assignee under the Assignment of Claims Act.

4.9 Indemnification; Risk of Loss. In any suit, proceeding or action brought by or against the Lender relating to the Collateral, the Borrowers will jointly and severally defend, indemnify and keep the Lender harmless from and against all expense, loss or damage (including reasonable attorneys’ fees) suffered by reason of any defense, set-off, counterclaim, recoupment or reduction of liability whatsoever of account debtor or other obligor of the Borrowers. The foregoing obligation of the Borrowers to indemnify the Lender shall survive the payment of the Credit Facilities and the termination of this Agreement, but shall not extend to any suit, proceeding or action arising out of the Lender’s gross negligence or willful misconduct.

In addition, the risk of any loss or damage associated with the Collateral, including without limitation, any Collateral in the possession of Lender shall be borne by the Borrowers; provided, that Lender shall be responsible for any loss resulting from Lender’s gross negligence or willful misconduct. In the event that Lender is in possession of Collateral, (a) Borrower shall be jointly and severally liable to Lender and shall pay to Lender, upon demand, all reasonable expenses, including the cost of insurance and payment of taxes or other charges, incurred in the custody, preservation, use or operation of the Collateral, and all such expenses shall be secured by the Collateral; and (b) Lender may use and operate the Collateral, as determined in its discretion, (i) to preserve the Collateral or its value, (ii) as permitted by an order of a court having competent jurisdiction, or (iii) as otherwise set forth herein or as previously or hereafter agreed to by Borrowers. Notwithstanding anything in this Agreement to the contrary, Lender shall have no duty and be under no obligation to collect any income accruing on the Collateral or to preserve any rights relating to the Collateral.

This power, being coupled with an interest and given to secure an obligation, is irrevocable so long as the Revolving Loan remains unsatisfied, or any Loan Document remains effective, as solely determined by the Lender. Lender shall have no obligation or duty to pursue any Person other than Borrowers for the amounts owing under or in connection with the Revolving Loan, this Agreement or the other Loan Documents, including without limitation any Guarantors or Persons pledging property to secure the Credit Facilities. To the extent such rights may now or hereafter exist, each Borrower waives the right to require Lender to pursue any Persons other than Borrowers to pay the amounts owing under the Revolving Note, Loan Agreement or other Loan Documents;

File any legal action or lawsuit and obtain a judgment for any and all amounts owing under the Revolving Note, this Agreement or the other Loan Documents, and in conjunction with any such action, Lender may pursue any ancillary remedies provided by law, including without limitation, attachment, garnishment, execution and levy;

j. Borrowers acknowledge that any failure to comply with their obligation regarding the Collateral, including (without limiting the generality of the foregoing) granting of Assignments and collection of the Accounts, shall cause irreparable harm to the Lender for which the Lender has no adequate remedy at law, and agrees that the Lender shall be entitled to specific performance, an injunction or other equitable relief to enforce the Borrowers’ obligations under this Agreement;

k. Require the Borrowers at any time and from time to time during the continuance of such Event of Default upon demand of the Lender deliver to the Lender cash or U.S. Treasury Bills with maturities of not more than thirty (30) days in an amount equal to the amount of issued or pending Letters of Credit as of such time.

ESSEX – Amended and Restated Credit Agreement 56

at any time and from time to time held by the Lender in the Default Collateral Account and any interest, income, earnings and proceeds thereof, all of which shall be a part of the Collateral hereunder. If any Event of Default shall occur and be continuing, the Lender is irrevocably authorized to make such withdrawals from the Default Collateral Account at any time and from time to time and apply the same to any of the Obligations (including, without limitation, Letter of Credit Obligations) in such order and manner as the Lender in its sole discretion may determine. After all Obligations have been indefeasibly paid in full and there are no Letters of Credit outstanding or any commitment on the part of the Lender to open and issue Letters of Credit, any cash, monies, funds, U.S. Treasury Bills or other securities and instruments held by the Lender in the Default Collateral Account will be turned over to the Borrowers or to such other person who may be entitled to the same under applicable laws.

l. In addition to the foregoing, and not in substitution therefor, exercise any one or more of the rights and remedies exercisable by the Lender under other provisions of this Agreement, under any of the other Loan Documents, or provided by applicable law (including, without limiting the generality of the foregoing, the Uniform Commercial Code), including without limitation, generally enforcing any or all of Borrowers’ rights and remedies against any Customers, provided that Lender shall be under no obligation to do so.

9.3 Application of Proceeds. Any proceeds from the collection or sale or other disposition of the Collateral shall be applied in the following order of priority:

First, to the payment of all expenses of collecting, storing, leasing, operating, managing, selling or disposing of the Collateral, and to the payment of all sums which the Lender may be required or may elect to pay, if any, for taxes, assessments, insurance and other charges upon such Collateral or any part thereof, and of all other payments which the Lender may be required or authorized to make under any provision of this Agreement or of any other Loan Document (including in each such case legal costs and attorneys’ fees and expenses);

Second, to the payment of all obligations on the Revolving Loan under this Agreement, and under the other Loan Documents, and to the payment of any other obligations due to the Lender, in such order as the Lender may determine in its sole discretion; and

Third, to the payment of any surplus then remaining to Borrowers, unless otherwise provided by law or directed by a court of competent jurisdiction; provided that Borrowers shall be liable for any deficiency if the proceeds of the Collateral are insufficient to satisfy all obligations due to the Lender.

ESSEX – Amended and Restated Credit Agreement 57

9.4 Collection/Enforcement Costs. Borrowers shall pay all costs and expenses incurred by Lender in connection with the enforcement of its rights under this Agreement and the other Loan Documents, including without limitation, legal costs and attorneys’ fees (whether or not suit is instituted), paralegal and expert witness fees and costs, and arbitration fees and costs, and in connection with the collection of any sums from Borrowers.

ARTICLE 10. MISCELLANEOUS PROVISIONS.

10.1 Additional Actions and Documents. Borrowers shall take or cause to be taken such further actions, shall execute, deliver and file or cause to be executed, delivered and filed such further documents and instruments, and shall obtain such consents as may be necessary or as the Lender may reasonably request in order fully to effectuate the purposes, terms and conditions of this Agreement and the other Loan Documents, whether before, at or after the closing of transactions contemplated hereby and thereby or the occurrence of an Event of Default hereunder, including without limitation, executing such documents and taking such further actions as requested by Lender to evidence or perfect the security interest(s) granted in accordance with this Agreement, to maintain a first priority security interest in the Collateral for the benefit of Lender, or to effectuate the rights of Lender hereunder.

10.2 Expenses. Borrowers shall, whether or not the transactions contemplated hereby are consummated, (i) reimburse the Lender and save the Lender harmless against liability for the payment of all out-of-pocket expenses arising in connection with: (a) the preparation, execution, delivery or filing of this Agreement or any of the Loan Documents (including the Lender’s attorneys’ fees, which the parties agree shall be capped at $12,000 for the initial documentation of the transactions set forth in this Agreement); or (b) the administration or enforcement of this Agreement or any of the Loan Documents; or (c) the preservation or exercise of any rights (including the right to collect and dispose of the Collateral) under this Agreement or any of the other Loan Documents; and (ii) pay and hold the Lender and each subsequent holder of the Note harmless from and against, any and all present and future stamp taxes or similar document taxes or recording taxes and any and all charges with respect to or resulting from any delay in paying, or failure to pay, such taxes. Without limiting the generality of the foregoing, the expenses covered by this paragraph include the Lender’s legal fees, the costs of audits or examinations conducted by the Lender’s employees and any arbitration fees or court costs.

10.3 Notices.

Any notices required under the Uniform Commercial Code with respect to the sale or other disposition of the Collateral shall be deemed reasonable if mailed by the Lender to the Persons entitled thereto at their last known address at least ten (10) days prior to disposition of the Collateral.

10.4 Severability. If fulfillment of any provision of the Loan Documents or performance of any transaction related thereto, at the time such fulfillment or performance shall be due, shall involve transcending the limit of validity prescribed by law, then the obligation to be fulfilled or performed shall be reduced to the limit of such validity; and if any clause or provision contained in any Loan Document operates or would operate prospectively to invalidate any Loan Document, in whole or in part, then such clause or provision only shall be held ineffective, as though not herein or therein contained, and the remainder of the Loan Documents shall remain operative and in full force and effect.

10.5 Survival. It is the express intention and agreement of the parties hereto that all covenants, agreements, statements, representations, warranties and indemnities made by Borrower in the Loan Documents shall survive the execution and delivery of the Loan Documents and the making of all Advances and extensions of credit thereunder.

10.6 Waivers. No waiver by the Lender of, or consent by the Lender to, a variation from the requirements of any provision of the Loan Documents shall be effective unless made in a written instrument duly executed on behalf of the Lender by its duly authorized officer, and any such waiver shall be limited solely to those rights or conditions expressly waived.

10.7 Rights Cumulative. The rights and remedies of the Lender described in any of the Loan Documents are cumulative and not exclusive of any other rights or remedies which the Lender or the then holder of the Revolving Note otherwise would have at law or in equity or otherwise.

All terms of this Agreement and of the other Loan Documents shall be binding upon, and shall inure to the benefit of and be enforceable by, the parties hereto and their respective successors and assigns; however, Borrower may not assign or transfer any of its rights or obligations hereunder without the prior written consent of the Lender. In the event of any conflict between the terms of this Agreement and the terms of the other Loan Documents, the terms of this Agreement shall control.

10.9 Setoff. In addition to any rights or remedies of the Lender provided by law, upon the occurrence of any Event of Default hereunder, or any event or circumstance which, with the giving of notice or the passage of time or both, would constitute an Event of Default hereunder, the Lender is irrevocably authorized, at any time or times without prior notice to Borrower, to set off, appropriate and apply any and all deposits, credits, indebtedness or claims at any time held or owing by the Lender to or for the credit or the account of Borrower, in such amounts as the Lender may elect, against and on account of the obligations and liabilities of Borrower to the Lender hereunder or under any of the other Loan Documents, whether or not the Lender has made any demand for payment, and although such obligations and liabilities may be contingent or unmatured.

10.10 Construction. This Agreement and the other Loan Documents, the rights and obligations of the parties hereto, and any claims or disputes relating thereto shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia (excluding the choice of law rules thereof) except to the extent that the UCC provides for either (a) the application of the laws of the state in which Borrower maintains its chief executive office, (b) the application of the laws of the state in which the collateral is located, (c) the application of the laws of the state in which the Debtor is located or (d) otherwise mandates the application of the laws of another state or jurisdiction..

10.12 Headings. Article, section and subsection headings contained in this Agreement are inserted for convenience of reference only, shall not be deemed to be a part of this Agreement for any purpose, and shall not in any way define or affect the meaning, construction or scope of any of the provisions hereof.

10.13 Payments.

10.15 Service of Process. The Borrower consents to process being served in any suit, action or proceeding by mailing a copy thereof by registered or certified mail postage prepaid, return receipt requested, to the Borrower’s address specified in or designated in this Agreement. The Borrower agrees that such service (i) shall be deemed in every respect effective service of process upon the Borrower in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by law, be taken and held to be valid personal service upon and personal delivery to the Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner permitted by law, or limit any right that the Lender may have to bring proceedings against the Borrower in the courts of any jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction.

10.16 Sale of Loan Documents; Disclosure of Information. Borrower hereby consents to and agrees that Lender may disclose to any Person in conjunction with an assignment or sale of Lender’s rights or interests in the Loan Documents, any and all

10.17 WAIVER OF JURY TRIAL. BY AGREEING TO BINDING ARBITRATION, BORROWERS AND LENDER IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF A CLAIM. FURTHERMORE, WITHOUT INTENDING IN ANY WAY TO LIMIT THIS AGREEMENT TO ARBITRATE, TO THE EXTENT ANY CLAIM IS NOT ARBITRATED, THE PARTIES IRREVOCABLY AND VOLUNTARILY WAIVE ANY RIGHT THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF SUCH CLAIM. THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES ENTERING THIS AGREEMENT.

10.18 ARBITRATION.

(a) This paragraph concerns the resolution of any controversies or claims between the parties, whether arising in contract, tort or by statute, including but not limited to controversies or claims that arise out of or relate to: (i) this Agreement (including any renewals, extensions or modifications); or (ii) any document related to this Agreement (collectively a “Claim”). For the purposes of this arbitration provision only, the term “parties” shall include any parent corporation, subsidiary or affiliate of the Lender involved in the servicing, management or administration of any obligation described or evidenced by this Agreement.

(b) At the request of any party to this Agreement, any Claim shall be resolved by binding arbitration in accordance with the Federal Arbitration Act (Title 9, U.S. Code) (the “Act”). The Act will apply even though this Agreement provides that it is governed by the law of a specified state. The arbitration will take place on an individual basis without resort to any form of class action.

(c) Arbitration proceedings will be determined in accordance with the Act, the then-current rules and procedures for the arbitration of financial services disputes of the American Arbitration Association or any successor thereof (“AAA”), and the terms of this paragraph. In the event of any inconsistency, the terms of this paragraph shall control. If AAA is unwilling or unable to (i) serve as the provider of arbitration or (ii) enforce any provision of this arbitration clause, any party to this agreement may substitute another arbitration organization with similar procedures to serve as the provider of arbitration.

ESSEX – Amended and Restated Credit Agreement 63

(d) The arbitration shall be administered by AAA and conducted in Washington, D.C. All Claims shall be determined by one arbitrator; however, if Claims exceed Five Million Dollars ($5,000,000), upon the request of any party, the Claims shall be decided by three arbitrators. All arbitration hearings shall commence within ninety (90) days of the demand for arbitration and close within ninety (90) days of commencement and the award of the arbitrator(s) shall be issued within thirty (30) days of the close of the hearing. However, the arbitrator(s), upon a showing of good cause, may extend the commencement of the hearing for up to an additional sixty (60) days. The arbitrator(s) shall provide a concise written statement of reasons for the award. The arbitration award may be submitted to any court having jurisdiction to be confirmed, judgment entered and enforced.

(e) The arbitrator(s) will give effect to statutes of limitation in determining any Claim and may dismiss the arbitration on the basis that the Claim is barred. For purposes of the application of the statute of limitations, the service on AAA under applicable AAA rules of a notice of Claim is the equivalent of the filing of a lawsuit. Any dispute concerning this arbitration provision or whether a Claim is arbitrable shall be determined by the arbitrator(s). The arbitrator(s) shall have the power to award reasonable legal fees pursuant to the terms of this Agreement.

(f) This paragraph does not limit the right of any party to: (i) exercise self-help remedies, such as but not limited to, setoff; (ii) initiate judicial or non-judicial foreclosure against any real or personal property collateral; (iii) exercise any judicial or power of sale rights, or (iv) act in a court of law to obtain an interim remedy, such as but not limited to, injunctive relief, writ of possession or appointment of a receiver, or additional or supplementary remedies.

(g) The filing of a court action is not intended to constitute a waiver of the right of any party, including the suing party, thereafter to require submittal of the Claim to arbitration.

ESSEX – Amended and Restated Credit Agreement 64

(h) By agreeing to binding arbitration, the parties irrevocably and voluntarily waive any right they may have to a trial by jury in respect of any Claim. Furthermore, without intending in any way to limit this agreement to arbitrate, to the extent any Claim is not arbitrated, the parties irrevocably and voluntarily waive any right they may have to a trial by jury in respect of such Claim. This provision is a material inducement for the parties entering into this Agreement.

10.19. No Novation. This Agreement is an agreement entirely amending and restating the provisions of the Original Loan Agreement. All of the provisions of the Original Loan Agreement are incorporated herein by reference and shall continue in full force an effect, as entirely amended and restated hereby. The Borrowers hereby ratify and confirm all of their obligations under the Original Loan Agreement, as entirely amended and restated hereby. The Borrowers agrees that it is their intention that nothing in this Agreement shall be construed to extinguish, release or discharge, or constitute, create or effect a novation of or an agreement to extinguish any of the obligations, under the Original Loan Agreement. In the event of any conflict between the provisions of this Agreement and the Original Loan Agreement, the provisions of this Loan Agreement shall take precedence and govern.

10.20. Termination of Security Interest. Upon (i) payment in full of the outstanding Obligations and (ii) the termination of the Credit Facilities (whether by the Lender pursuant to the provisions of this Agreement or upon the request of the Borrowers) the security interest granted hereby shall terminate and all rights to the Collateral shall revert to the Borrowers. Upon any such termination, the Lender will execute and deliver to the Borrowers such documents as the Borrowers shall reasonably request to evidence such termination.
