In the event that the principal balance outstanding under the LOAN ever exceeds the MAXIMUM LOAN AMOUNT or such other limitations, the BORROWERS shall immediately, upon the demand of the LENDER, reduce the principal balance of the LOAN to an amount which is not in excess of the MAXIMUM LOAN AMOUNT or such limitations. Any termination of the LOAN by the LENDER shall relieve the LENDER of the LENDER’S obligation to lend money or to make financial accommodations to or for any or all of the BORROWERS and the BORROWERS’ accounts, and shall in no way release, terminate, discharge or excuse any of the BORROWERS from its absolute duty to pay or perform the OBLIGATIONS.

Section 2.1.1. Revolving Loan Promissory Note. The obligations of the BORROWERS to repay the LOAN to the LENDER shall be further evidenced by the REVOLVING LOAN PROMISSORY NOTE.

Section 2.1.2. Procedure For Revolving Loan Borrowings. The BORROWERS may borrow proceeds of the LOAN until (but not including) the MATURITY DATE, provided, that the BORROWERS deliver to the LENDER an irrevocable notice (which notice must be received by the LENDER prior to 10:00 a.m. Baltimore, Maryland time on the requested BORROWING DATE) specifying: (i) the amount to be borrowed, (ii) the requested BORROWING DATE, (iii) whether the borrowing is to be a LIBOR BORROWING, a BASE RATE BORROWING, or a combination thereof, and (iv) if the borrowing is to be entirely or partly a LIBOR BORROWING, the notice of election described in Section 2.2.2 of this AGREEMENT.

Section 2.2. Interest Terms Applicable To The Loan. Interest shall accrue upon the unpaid principal balance of the LOAN until the LOAN has been repaid in full at the rate or rates described below in this Section 2.2.

Section 2.2.1. Adjusted Base Rate. Except as otherwise provided by the terms of this AGREEMENT, the LOAN shall bear interest on the unpaid principal balance at the fluctuating ADJUSTED BASE RATE. Absent a timely election by the BORROWERS in accordance with Section 2.2.2 of this AGREEMENT, the unpaid balance of the LOAN, including any balance of any LIBOR BORROWING for which the applicable INTEREST PERIOD has expired, automatically shall be deemed to bear interest at the ADJUSTED BASE RATE. Changes in the interest rate shall be made when and as changes in the BASE RATE occur. For each BASE RATE BORROWING, all accrued and unpaid interest shall be payable monthly in arrears on each consecutive PAYMENT DATE. Each election by the BORROWERS of a BASE RATE BORROWING shall be in the MINIMUM BORROWING AMOUNT, or any multiple thereof.

Section 2.2.2. Adjusted LIBOR Rate Option. Subject to the terms of this Section, interest may accrue at the election of the BORROWERS for INTEREST PERIODS selected by the BORROWERS, at the ADJUSTED LIBOR RATE on portions of the unpaid principal balance of the LOAN. Any LIBOR BORROWING or election for a LIBOR BORROWING pursuant to the provisions of this Section shall be subject to the following terms and conditions:

a. Payments. For each of the LIBOR BORROWINGS, accrued interest shall be paid to the LENDER in arrears on each consecutive PAYMENT DATE during each INTEREST PERIOD and on the last day of each applicable INTEREST PERIOD.

b. Notice Of Election. By 10:00 a.m. Baltimore, Maryland time on the BUSINESS DAY on which the BORROWERS desire that an INTEREST PERIOD commence, the BORROWERS shall deliver a written election to the LENDER specifying: (1) the commencement date of the relevant INTEREST PERIOD; and (2) the dollar amount of that portion of the total aggregate principal amount of the applicable LOAN which is to bear interest at the ADJUSTED LIBOR RATE, which amount shall not be less than the MINIMUM BORROWING AMOUNT or any multiple thereof.

c. Effect Of Election. Interest shall accrue from and including the first day of each INTEREST PERIOD selected by the BORROWERS to (but not including) the last day of such INTEREST PERIOD at the ADJUSTED LIBOR RATE determined as applicable to such INTEREST PERIOD upon the amount of the unpaid principal balance of the LOAN identified by the BORROWERS in the BORROWERS’ written election.

(i) Interest Periods. There shall be no more than one (1) INTEREST PERIOD outstanding at any one time. No INTEREST PERIOD may expire after the MATURITY DATE.

(ii) Availability. If the LENDER determines at any time that a REGULATORY CHANGE or a change in market conditions has made it impractical for the LENDER to offer pricing based on the ADJUSTED LIBOR RATE, the LENDER may give notice of such determination to the BORROWERS, and all advances which are then accruing interest at an ADJUSTED LIBOR RATE shall, on the last day(s) of the then applicable current INTEREST PERIOD(S) automatically and without further notice, begin to accrue interest at the ADJUSTED BASE RATE. Until such time as the LENDER determines that a REGULATORY CHANGE or a change in market conditions has again made it practical for the LENDER to offer pricing at the ADJUSTED LIBOR RATE, the LENDER will not be obligated to further offer pricing based upon the ADJUSTED LIBOR RATE, and any notice from the BORROWERS requesting such a rate option will be ineffective.

(iii) Breakage Costs. Each of the BORROWERS, jointly and severally, agrees to compensate the LENDER from time to time, upon demand from the LENDER, for all losses, expenses, lost earnings, costs and liabilities (including, without limitation, all interest paid to lenders of funds

borrowed by the LENDER to carry LIBOR BORROWINGS) which the LENDER sustains if: (a) any repayment or prepayment of any LIBOR BORROWINGS (including, without limitation, any payment resulting from the acceleration of the LOAN in accordance with the terms of this AGREEMENT) or any conversion of a LIBOR BORROWING for any reason occurs on a date which is not the last day of the applicable INTEREST PERIOD; or (b) any failure by the BORROWERS to borrow a LIBOR BORROWING or convert a BASE RATE BORROWING to a LIBOR BORROWING on the date for such borrowing or conversion specified in the relevant notice of election given by the BORROWERS to the LENDER in accordance with the terms of this AGREEMENT.

(iv) Termination Of Right To Elect LIBOR Borrowings. Notwithstanding anything to the contrary set forth in this AGREEMENT, and without limiting any other rights and remedies of the LENDER, the LENDER during any continuing DEFAULT may suspend the right of the BORROWERS to convert any BASE RATE BORROWING into a LIBOR BORROWING or to permit any LIBOR BORROWING to be renewed as a LIBOR BORROWING, in which case the LOAN shall be converted (on the last days of the respective INTEREST PERIODS therefor) or continued, as the case may be, as a BASE RATE BORROWING.

Section 2.2.3. Calculation Of Interest. Interest shall be calculated upon LIBOR BORROWINGS on the basis of a 365 or 366 days per year factor applied to the actual days on which there exists an unpaid balance of the LIBOR BORROWINGS. Interest shall be calculated upon BASE RATE BORROWINGS on the basis of a 360 day per year factor applied to the actual days on which there exists an unpaid balance of the BASE RATE BORROWINGS.

Section 2.2.4. Default Interest. The interest rates payable upon the LOAN may be increased during any continuing EVENT OF DEFAULT by the LENDER to that rate (the “DEFAULT RATE”) equal to the BASE RATE plus four hundred (400) BASIS POINTS until the EVENT OF DEFAULT has been cured to the satisfaction of the LENDER.

Section 2.2.5. Maximum Rate Of Interest. Any provision contained in the LOAN DOCUMENTS to the contrary notwithstanding, the LENDER shall not be entitled to receive or collect, nor shall the BORROWERS be obligated to pay, interest, fees, or charges thereunder in excess of the maximum rate of interest permitted by any applicable LAW, and if any provision of this AGREEMENT, the NOTE or any of the other LOAN DOCUMENTS is construed or held by any court of law or GOVERNMENTAL BODY having jurisdiction to permit or require the charging, collection or payment of any amount of interest in excess of that permitted by such LAWS, the provisions of this Section shall control and shall override any contrary or inconsistent provision. The intention of the parties is to at all times conform strictly with all applicable usury requirements and other LAWS limiting the maximum rates of interest which may be lawfully charged upon the LOAN. The interest to be paid pursuant to the NOTE shall be held subject to reduction to the amount allowed under said usury or other laws as now or hereafter construed by the courts having jurisdiction, and any sums of money paid in excess of the interest rate allowed by applicable law shall be applied in reduction of the principal amount owing pursuant to the NOTE. Each of the BORROWERS acknowledges and irrevocably stipulates for all purposes that it has been contemplated at all times by the parties that the LAWS of the State of Maryland will govern the maximum rate of interest that it is permissible for the LENDERS to charge the BORROWERS.

Section 2.3. Late Payment Charges. Any payment of principal, interest or fees due upon the LOAN (including any final payment) which is received by the LENDER more than fifteen (15) calendar days after its due date shall incur a late payment charge equal to five percent (5%) of the amount of the payment due. All late payment charges shall be payable upon the demand of the LENDER. The existence of the right by the LENDER to receive a late payment charge shall not be deemed to constitute a grace period or provide any right to the BORROWERS to make a payment other than on such payment’s scheduled due date.

Section 2.4. Voluntary Prepayments. Any principal balance of the LOAN accruing interest at the ADJUSTED LIBOR RATE may be prepaid in whole or in part at any time without penalty or premium upon notice to the LENDER not less than two (2) BUSINESS DAYS prior to the date of repayment, provided that the LENDER is compensated for any breakage costs incurred by the LENDER as a result of any such repayment in accordance with the

provisions of Section 2.2.2 (d) of this AGREEMENT. Any principal balance of the LOAN bearing interest at the BASE RATE may be prepaid in whole or in part at any time without penalty or premium.

Section 2.5. Yield Protection. If the adoption or change of any LAW, rule, or any change in the interpretation or administration thereof by any GOVERNMENTAL AUTHORITY, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by the LENDER with any request or directive (whether or not having the force of law) of any such GOVERNMENTAL AUTHORITY, central bank, or comparable agency or any REGULATORY CHANGE after the date of CLOSING: (a) subjects the LENDER to any tax, duty, or other charge with respect to the LOAN, or changes the basis of taxation of any amounts payable to the LENDER under this AGREEMENT or otherwise with respect to any OBLIGATIONS (other than taxes imposed on the overall net income of the LENDER by the jurisdiction in which the LENDER has its principal office); (b) imposes, modifies, or deems applicable any reserve, special deposit, assessment, compulsory loan, or similar requirement (other than the RESERVE REQUIREMENT utilized in the determination of the ADJUSTED LIBOR RATE) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, the LENDER, including the LOAN, extended by the LENDER hereunder or any other OBLIGATIONS owing to the LENDER; or (c) imposes on the LENDER or the applicable interbank market any other condition affecting this AGREEMENT or any OBLIGATION or any of such extensions of credit or liabilities or commitments or the costs of deposits maintained by the LENDER in obtaining funds to carry the LOAN or any of the other OBLIGATIONS; and the result of any of the foregoing is to increase the cost to the LENDER of the making, converting into, continuing, or maintaining or participating in the LOAN or other OBLIGATIONS or to reduce any yield or sum received or receivable by the LENDER under this AGREEMENT with respect to any LOAN or other OBLIGATION, then the BORROWERS, jointly and severally, agree to pay to the LENDER on demand such amount or amounts as will compensate the LENDER for such increased cost or reduction. If the LENDER claims compensation under this Section, the LENDER shall furnish to the BORROWERS a statement setting forth the reason and the additional amount or amounts to be paid to the LENDER hereunder which shall be conclusive in the absence of manifest error. In determining such amount, the LENDER may use any reasonable averaging and attribution methods.

Section 2.6. Lender’s Records. The date and amounts of each advance made by the LENDER and each payment made by any of the BORROWERS shall be recorded by the LENDER on the books and records of the LENDER, but any failure to record such dates or amounts shall not relieve any of the BORROWERS of its duties and obligations under the LOAN DOCUMENTS. Interest accrued upon the LOAN shall be computed on outstanding balances as reflected on the LENDER’S books and records.

Section 2.7. Commitment Fee. For each calendar quarter or portion thereof during which the LOAN is in existence and has not been terminated, until the termination of the LOAN, the BORROWERS shall pay to the LENDER a commitment fee of one-quarter of one percent (1/4%) per annum on that sum obtained by subtracting the average daily disbursed principal balance of the LOAN during such calendar quarter or portion thereof from the DOLLAR CAP, less One Million Dollars ($1,000,000.00). The commitment fee shall be payable quarterly in arrears, on the first day of each succeeding quarter or on the last day of a portion of a quarter commencing with the first of such payments to be made on January 1, 2006. The commitment fee is not to be considered a fee being paid by the BORROWERS to the LENDER as an inducement to the LENDER to make advances, nor shall it be considered to modify or limit the ability of the LENDER to terminate in accordance with the provisions of this AGREEMENT the ability of the BORROWERS to borrow under the LOAN, but is instead intended as part of the compensation which is earned by the LENDER for agreeing to provide the LOAN in accordance with the terms of the LOAN DOCUMENTS.

Section 2.8. Conditions Precedent To Each Advance. The obligation of the LENDER to make any advances under the LOAN, including the initial advance, shall be subject to the procedures set forth in Sections 2.1.2 and 2.2 below and to each of the following conditions precedent:

Section 2.8.1. No Defaults Or Events Of Default. No event shall have occurred on or prior to such date and be continuing on such date, and no condition shall exist on such date, which constitutes a DEFAULT or EVENT OF DEFAULT.

Section 2.8.2. Continuing Accuracy Of Representations And Warranties. Each of the representations and warranties made by or on behalf of the BORROWERS or by the GUARANTOR to the LENDER in

the LOAN DOCUMENTS shall be true and correct in all material respects when made and shall be deemed to be repeated as true, accurate and complete as of the date of the BORROWERS’ request for each advance.

Section 2.8.3. Receipt Of Reports. The LENDER shall be in receipt of all reports, financial statements, financial information and financial disclosures required by the LOAN DOCUMENTS, except to the extent that the LENDER has waived the receipt thereof.

Section 2.8.4. Subordination Agreements. The HINDMAN NOTE, and any security interest securing same, shall be subordinated to the OBLIGATIONS and to the liens and security interests of the LENDER on terms and conditions satisfactory to the LENDER.

No LETTER OF CREDIT shall have an expiry date which occurs after the stated maturity date or termination date of the LOAN. Any amounts paid by the LENDER in connection with any LETTER OF CREDIT shall be treated as an advance of proceeds of the LOAN, shall be secured by all of the COLLATERAL, and shall bear interest (including the default rate of interest) and be payable at the same rate and in the same manner as the LOAN.

Section 2.9.2. Rights And Remedies Of The Lender. In the event that, coincident with or subsequent to the occurrence of, and during the continuance of, a DEFAULT or an EVENT OF DEFAULT, the LENDER becomes aware of the possibility of a draw, or enforcement of the LENDER’S obligations, under a LETTER OF CREDIT, the LENDER, at its option, may, but shall not be required to, pay the obligations to the beneficiary or holder of such LETTER OF CREDIT directly to such beneficiary or holder, and, in such event, the amount of any such payment made by the LENDER shall be treated for all purposes and shall have the same force and effect as if such amount had been loaned by the LENDER to the BORROWERS as an advance of proceeds of the LOAN, shall be secured by all of the COLLATERAL and shall bear interest and be payable at the same rate (including the default rate of interest) and in the same manner as the LOAN. If any LETTER OF CREDIT is drawn upon to discharge any obligation of any of the BORROWERS to the beneficiary of such LETTER OF CREDIT, in whole or in part, the LENDER shall be fully subrogated to the rights of such beneficiary with respect to the obligations owed by such BORROWER to such beneficiary discharged with the proceeds of the LETTER OF CREDIT.

Section 2.9.3. Indemnification. The BORROWERS jointly and severally and unconditionally and irrevocably agree to indemnify the LENDER and to hold the LENDER harmless from any and all losses, claims or liabilities arising from any transactions or occurrences relating to LETTERS OF CREDIT issued, established, opened or accepted for the account of any of the BORROWERS, and any drafts or acceptances thereunder, and all OBLIGATIONS incurred in connection therewith, other than losses, claims or liabilities arising from the gross negligence or wanton misconduct of the LENDER.

of the payment of the presented draft by the LENDER) upon any LETTER OF CREDIT (either with the proceeds of the LOAN obtained hereunder or otherwise) in same day funds in the amount of the drawing. If the BORROWERS fail to reimburse the LENDER as provided herein or as provided in any separate letter of credit application agreements or other LOAN DOCUMENTS, the unreimbursed amount of such drawing shall bear interest at a per annum rate equal to the highest interest rate (including the default rate of interest) applicable to the LOAN. The BORROWERS’ reimbursement obligations hereunder shall be absolute and unconditional under all circumstances irrespective of any rights of set-off, counterclaim or defense to payment any of the BORROWERS may claim or have against the LENDER, the beneficiary of the LETTER OF CREDIT or any other PERSON, including, without limitation, any defense based on any failure of any of the BORROWERS to receive consideration or the legality, validity, regularity or unenforceability of the LETTER OF CREDIT or any irregularities in the presentment of the draft presented upon the LETTER OF CREDIT.

Section 2.9.5. Fees, Charges And Other Terms. The BORROWERS jointly and severally agree to pay to the LENDER such issuance, amendment, extension and other fees as the LENDER quotes from time to time with respect to each LETTER OF CREDIT, and shall execute such applications, reimbursement agreements, or other documents as the LENDER requires from time to time with respect to the issuance, extension, amendment, or any other requested or required action concerning a LETTER OF CREDIT.

Section 2.10. Capital Adequacy. If the LENDER determines at any time that the adoption or implementation of any CAPITAL ADEQUACY REQUIREMENT, or the compliance therewith by the LENDER or any corporation or other PERSON controlling the LENDER, affects the amount of capital to be maintained by the LENDER or any PERSON controlling the LENDER as a result of its obligations hereunder, or reduces the effective rate of return on the LENDER’S or such controlling PERSON’S capital to a level below that which the LENDER or such controlling PERSON would have achieved but for such CAPITAL ADEQUACY REQUIREMENT as a consequence of its obligations hereunder (taking into consideration the LENDER’S or such controlling PERSON’S policies with respect to capital adequacy), then after submission by the LENDER to the BORROWERS of a written request therefor and a statement of the basis for such determination, the BORROWERS shall pay to the LENDER such additional amounts as will compensate the LENDER or the controlling PERSON for the cost of maintaining the increased capital or for the reduction in the rate of return on capital, together with interest thereon at the highest rate of interest then in effect under the NOTE from the date the LENDER requests such additional amounts until those amounts are paid in full.

Section 2.11. Payments. All payments received by the LENDER which are to be applied to reduce the OBLIGATIONS shall be credited to the balances due from any or all of the BORROWERS pursuant to the normal and customary practices of the LENDER, but shall be provisional and shall not be considered final unless and until such payment is not subject to avoidance under any provision of the United States Bankruptcy Code, as amended, including Sections 547 and 550, or any state law governing insolvency or creditors’ rights. If any payment is avoided or set aside under any provision of the United States Bankruptcy Code, including Sections 547 and 550, or any state law governing insolvency or creditors’ rights, the payment shall be considered not to have been made for all purposes of this AGREEMENT and the LENDER shall adjust its records to reflect the fact that the avoided payment was not made and has not been credited against the OBLIGATIONS.

Section 2.12. Advancements. If any of the BORROWERS fails to perform any of its agreements or covenants contained in this AGREEMENT or if any of the BORROWERS fails to protect or preserve the COLLATERAL or the status and priority of the security interest of the LENDER in the COLLATERAL, the LENDER may make advances to perform the same on behalf of such BORROWER to protect or preserve the COLLATERAL or the status and priority of the security interest of the LENDER in the COLLATERAL, and all sums so advanced shall immediately upon advance become secured by the security interests granted in this AGREEMENT, and shall become part of the principal amount owed to the LENDER with interest to be assessed at the applicable rate thereon and subject to the terms and provisions of this AGREEMENT and all of the LOAN DOCUMENTS. The BORROWERS shall repay on demand all sums so advanced on any BORROWER’S behalf, plus all expenses or costs incurred by the LENDER, including reasonable legal fees, with interest thereon at the highest rate authorized in the NOTE. The provisions of this Section shall not be construed to prevent the institution of the rights and remedies of the LENDER upon the occurrence of an EVENT OF DEFAULT. The authorization contained in this Section is not intended to impose any duty or obligation on the LENDER to perform any action or make any advancement on behalf of any or all of the BORROWERS and is intended to be for the sole benefit and protection of the LENDER.

Section 2.13.1. Cross-Guaranty.

The liability of each BORROWER hereunder is direct and unconditional as to all of the OBLIGATIONS, and may be enforced without requiring the LENDER first to resort to any other right, remedy or security.

Section 2.13.2. Postponement Of Subrogation. Until all of the OBLIGATIONS are paid in full, no BORROWER shall have any right of subrogation, reimbursement or indemnity whatsoever, nor any right of recourse to security for any of the OBLIGATIONS, and nothing shall discharge or satisfy the liability of a BORROWER hereunder, until the full, final and absolute payment and performance of all of the OBLIGATIONS at any time after all commitments of the LENDER under this AGREEMENT are terminated. Any and all present and future debts and obligations of each BORROWER to each other BORROWER are hereby waived and postponed in favor of and subordinated to the full payment and performance of all present and future OBLIGATIONS.

Section 2.13.3. Subordination. Each BORROWER hereby subordinates any claims (other than claims evidenced by notes which have been assigned and delivered to the LENDER), including, without limitation, any other right of payment, subrogation, contribution and indemnity that it may have from or against the other BORROWERS, and any successor or assign of the other BORROWER, including, without limitation, any trustee, receiver or debtor-in-possession, howsoever arising, due or owing and whether heretofore, now or hereafter existing, to all of the OBLIGATIONS of the other BORROWERS to the LENDER.

Section 2.14. Joint And Several Liability; Appointment Of Agent. Notwithstanding anything to the contrary contained herein, the BORROWERS shall be jointly and severally liable to the LENDER for all OBLIGATIONS, regardless of whether such OBLIGATIONS arise as a result of credit extensions to one BORROWER, it being stipulated and agreed that the LOAN, the LETTERS OF CREDIT, and all of the credit extensions hereunder to one BORROWER inure to the benefit of all BORROWERS, and that the LENDER is relying on the joint and several liability of the BORROWERS in extending the LOAN and in issuing any of the LETTERS OF CREDIT and in providing credit hereunder.

ARTICLE 8.

RIGHTS AND REMEDIES ON THE

OCCURRENCE OF AN EVENT OF DEFAULT

Section 8.1. Lender’s Specific Rights And Remedies. In addition to all other rights and remedies provided by LAW and the LOAN DOCUMENTS, upon the occurrence of any EVENT OF DEFAULT, the LENDER may: (a) accelerate and call immediately due and payable all or any part of the OBLIGATIONS; (b) seek specific performance or injunctive relief to enforce performance of the undertakings, duties, and agreements provided in the LOAN DOCUMENTS, whether or not a remedy at law exists or is adequate; and (c) exercise any rights of a secured creditor under the Uniform Commercial Code, as adopted and amended in Maryland, including the right to take possession of the COLLATERAL without the use of judicial process or hearing of any kind and the right to require any or all of the BORROWERS to assemble the COLLATERAL at such place as the LENDER may specify.

Section 8.2. Automatic Acceleration. Upon the occurrence of an EVENT OF DEFAULT as described in Sections 7.9 or 7.10 of this AGREEMENT, the OBLIGATIONS shall be automatically accelerated and due and payable without any notice, demand or action of any type on the part of the LENDER.

Section 8.3. Sale Of Collateral. In addition to any other remedy provided herein, upon the occurrence of an EVENT OF DEFAULT, the LENDER, in a commercially reasonable fashion, may sell at public or private sale or otherwise realize upon, in Baltimore, Maryland, or elsewhere, the whole or, from time to time, any part of all COLLATERAL which is personal property, or any interest which any of the BORROWERS may have therein. Pending any such action, the LENDER may collect and liquidate the COLLATERAL. After deducting from the proceeds of sale or other disposition of such COLLATERAL all expenses, including all expenses for legal services, the LENDER shall apply such proceeds toward the satisfaction of the OBLIGATIONS. Any remainder of the proceeds after satisfaction in full of the OBLIGATIONS shall be distributed as required by applicable LAW. Notice of any sale or other disposition (other than sales or other dispositions of COLLATERAL which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market) shall be given to the BORROWERS not less than ten (10) calendar days before the time of any intended public sale or of the time after which any intended private sale or other disposition of the COLLATERAL is to be made, which each of the BORROWERS hereby agrees shall be commercially reasonable notice of such sale or other disposition. The BORROWERS shall assemble, or shall cause to be assembled, at the BORROWERS’ own expense, the COLLATERAL at such place or places as the LENDER shall designate. At any such sale or other disposition, the LENDER may, to the extent permissible under applicable law, purchase the whole or any part of the COLLATERAL, free from any right of redemption on the part of any of the BORROWERS, which right is hereby waived and released to the extent lawfully permitted. Without limiting the generality of any of the rights and remedies conferred upon the LENDER under this Section, the LENDER may, to the full extent permitted by applicable law: (a) enter upon the premises of any of the BORROWERS, exclude therefrom any of the BORROWERS or any PERSON connected therewith, and take immediate possession of the COLLATERAL, either personally or by means of a receiver appointed by a court of competent jurisdiction, using all necessary force to do so; (b) at the LENDER’S option,

use, operate, manage, and control the COLLATERAL in any lawful manner; (c) collect and receive all income, revenue, earnings, issues, and profits therefrom; and (d) maintain, alter or remove the COLLATERAL as the LENDER may determine in the LENDER’S discretion.

Section 8.4. Letters Of Credit. Upon the request of the LENDER, at any time after the occurrence of an EVENT OF DEFAULT, the BORROWERS shall immediately deposit in a cash collateral account at the LENDER, over which the LENDER has sole access, an amount equal to the aggregate then undrawn and unexpired amount of all LETTERS OF CREDIT. Amounts held in such cash collateral account shall be applied by the LENDER to the payment of drafts drawn under LETTERS OF CREDIT, and the unused portion thereof after all LETTERS OF CREDIT shall have expired or been fully drawn upon shall be applied to repay the other OBLIGATIONS. After all LETTERS OF CREDIT shall have expired or have been fully drawn upon and all other OBLIGATIONS shall have been paid in full, the balance, if any, in such cash collateral account shall be returned to the BORROWERS. In the event the BORROWERS fail to deposit into the cash collateral account an amount equal to the then undrawn and unexpired amount of all LETTERS OF CREDIT, the LENDER shall be authorized to deposit into such cash collateral account proceeds from the liquidation of the COLLATERAL until the balance in such account equals the aggregate then undrawn and unexpired amount of all LETTERS OF CREDIT.

Section 8.5. Remedies Cumulative. The rights and remedies provided in this AGREEMENT and in the other LOAN DOCUMENTS or otherwise under applicable LAWS shall be cumulative and the exercise of any particular right or remedy shall not preclude the exercise of any other rights or remedies in addition to, or as an alternative of, such right or remedy.

ARTICLE 9.

GENERAL CONDITIONS AND TERMS

Section 9.1. Obligations Are Unconditional. The payment and performance of the OBLIGATIONS shall be the absolute and unconditional joint and several duty and obligation of each of the BORROWERS, and shall be independent of any defense or any rights of set-off, recoupment or counterclaim which any of the BORROWERS might otherwise have against the LENDER. The BORROWERS shall pay the payments of the principal and interest to be made upon the OBLIGATIONS, free of any deductions and without abatement, diminution or set-off other than those herein expressly provided. Until such time as the OBLIGATIONS have been fully paid and performed, none of the BORROWERS shall: (a) suspend or discontinue any payments required by the LOAN DOCUMENTS; and (b) fail to perform and observe all of each BORROWER’S covenants and agreements set forth in the LOAN DOCUMENTS.

Section 9.2. Indemnity. Each of the BORROWERS agrees to defend, indemnify and hold harmless the LENDER and the entities affiliated with the LENDER and all of the LENDER’S and its affiliated entities’ employees, agents, officers and directors, from and against any losses, penalties, fines, liabilities, settlements, damages, costs and expenses, suffered in connection with any claim, investigation, litigation or other proceeding (whether or not the LENDER or an affiliated entity is a party thereto) and the prosecution and defense thereof, arising out of or in any way connected with any LOAN DOCUMENT, including without limitation reasonable attorneys’ and consultant’s fees, except to the extent that any of the foregoing directly result from the gross negligence or willful misconduct of the party seeking indemnification therefor. Notwithstanding any termination of this AGREEMENT or payment and performance of the OBLIGATIONS, the indemnities provided for herein shall continue in full force and effect and shall protect all of the above-described PERSONS against events arising after such termination, payment or performance as well as before.

Section 9.3. Lender Expenses. All LENDER EXPENSES shall be paid by the BORROWERS, whether incurred prior to or after CLOSING, such that the subject transactions shall at all times be cost free to the LENDER.

Section 9.4. Authorization To Obtain Financial Information. Each of the BORROWERS hereby irrevocably authorizes its accounting firm to provide the LENDER from time to time with such information as may be requested by the LENDER, and hereby authorizes the LENDER to contact directly such accounting firm in order to obtain such information.

Section 9.5. Incorporation; Construction Of Inconsistent Provisions. The terms and conditions of the LOAN DOCUMENTS are incorporated by reference and made a part hereof, as if fully set forth herein. In the event of any inconsistency between this AGREEMENT and any other LOAN DOCUMENT, such inconsistency shall be construed, interpreted, and resolved so as to benefit the LENDER, independent of whether this AGREEMENT or another LOAN DOCUMENT controls, and the LENDER’S election of which interpretation or construction is for the LENDER’S benefit shall govern.

Section 9.6. Waivers. The LENDER at any time or from time to time may waive all or any rights under this AGREEMENT or any other LOAN DOCUMENT, but any waiver or indulgence by the LENDER at any time or from time to time shall not constitute a future waiver of performance or exact performance by any of the BORROWERS.

Section 9.7. Continuing Obligation Of Borrowers. The terms, conditions, and covenants set forth herein and in the LOAN DOCUMENTS shall survive CLOSING and shall constitute a continuing obligation of each of the BORROWERS during the course of the transactions contemplated herein. The security interests, liens and other security provided by this AGREEMENT shall remain in effect so long as any OBLIGATION, whether direct or contingent, is outstanding, unpaid or unsatisfied.

Section 9.8. Choice Of Law. The laws of the State of Maryland (excluding, however, conflict of law principles) shall govern and be applied to determine all issues relating to this AGREEMENT and the rights and obligations of the parties hereto, including the validity, construction, interpretation, and enforceability of this AGREEMENT and its various provisions and the consequences and legal effect of all transactions and events which resulted in the execution of this AGREEMENT or which occurred or were to occur as a direct or indirect result of this AGREEMENT having been executed.

Section 9.9. Submission To Jurisdiction; Venue; Actions Against Lender. For purposes of any action, in law or in equity, which is based directly or indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter related to this AGREEMENT or any other LOAN DOCUMENT, including any action for recognition or enforcement of any of the LENDER’S rights under the LOAN DOCUMENTS or any judgment obtained by the LENDER in respect thereof, each of the BORROWERS hereby:

Section 9.9.1. Jurisdiction. Irrevocably submits to the non-exclusive general jurisdiction of the courts of the State of Maryland and, if a basis for federal jurisdiction exists at any time, the courts of the United States of America for the District of Maryland.

Section 9.9.2. Venue. Agrees that venue shall be proper in the Circuit Court for Baltimore City, Maryland, the Circuit Court for any county in the state of Maryland, as selected by the LENDER, and, if a basis for federal jurisdiction exists, the courts of the United States of America for the District of Maryland.

Section 9.9.3. Waiver Of Objections To Venue. Waives any right to object to the maintenance of any suit in any of the courts specified in Section 9.9.2 above on the basis of improper venue or convenience of forum. Each of the BORROWERS further agrees that it shall not institute any suit or other action against the LENDER, in law or in equity, which is based directly or indirectly on this AGREEMENT, any other LOAN DOCUMENT or any matter related to this AGREEMENT or any other LOAN DOCUMENT, in any court other than a court specified in Section 9.9.2 above; provided, that in any instance in which there is then pending a suit instituted by the LENDER against any of the BORROWERS in a court other than a court specified in Section 9.9.2 above, each of the BORROWERS may file in such suit any counterclaim which it has against the LENDER but only if such counterclaim is a compulsory counterclaim and would be barred if not filed as a counterclaim in such suit. Each of the BORROWERS agrees that any suit brought by it against the LENDER not in accordance with this paragraph should be forthwith dismissed or transferred to a court specified in Section 9.9.2 above.

Section 9.10. Notices. Any notice required or permitted by or in connection with this AGREEMENT shall be in writing and shall be made by facsimile (confirmed on the date the facsimile is sent by one of the other methods of giving notice provided for in this Section) or by hand delivery, by Federal Express, or other similar overnight delivery service, or by certified mail, unrestricted delivery, return receipt requested, postage prepaid, addressed to the LENDER or the BORROWERS at the appropriate address set forth below or to such other address as may be hereafter specified by

written notice by the LENDER or the BORROWERS. Notice shall be considered given as of the date of the facsimile or the hand delivery, one (1) calendar day after delivery to Federal Express or similar overnight delivery service, or three (3) calendar days after the date of mailing, independent of the date of actual delivery or whether delivery is ever in fact made, as the case may be, provided the giver of notice can establish the fact that notice was given as provided herein. If notice is tendered pursuant to the provisions of this Section and is refused by the intended recipient thereof, the notice, nevertheless, shall be considered to have been given and shall be effective as of the date herein provided.
