Section 3.2             Late Charge.  The Borrower shall pay a “late charge” equal to five percent (5%) of any installment of principal or interest, or of any other amount due to the Lender under this Agreement which is not paid within ten (10) days of the due date thereof to defray the extra expense involved in handling such delinquent payment, provided that the “late charge” shall not be applicable upon any acceleration of the Obligations.  The minimum late charge shall be thirty-five Dollars ($35.00).

Section 3.3             Manner of Payment.  Each payment by the Borrower to Lender pursuant to this Agreement or the Revolving Credit Note shall be made not later than 1:00 p.m. (Hartford time) on the date specified for payment under this Agreement to the Lender by wire to the account designated from time to time by the Lender in writing to the Borrower, for the account of the Lender (except as specified below), in Dollars, in immediately available funds and shall be made without any set-off, counterclaim or deduction whatsoever.  Any payment received after such time but before 2:00 p.m. (Hartford time) on such day shall be deemed a payment on such date for the purposes of Section 10.1, but for all other purposes shall be deemed to have been made on the next succeeding Business Day.  Any payment received after 2:00 p.m. (Hartford time) shall be deemed to have been made on the next succeeding Business Day for all purposes.  If any payment under this Agreement or the Revolving Credit Note shall be specified to be made upon a day which is not a Business Day, it shall be made on the next succeeding day which is a Business Day, and such extension of time shall in such case be included in computing any interest if payable along with such payment and for all other purposes and calculations hereunder.

Section 3.4             Intentionally Deleted.

Section 3.5             Voluntary Prepayment of the Revolving Credit Loan.  The Revolving Credit Loan may be prepaid at any time, without premium or penalty.  Any interest accrued on the amounts so prepaid to the date of such payment must be paid at the time of any such payment.

Section 3.6             Increased Capital Costs.  If, after the date of this Agreement, any change in Applicable Law affects the amount of capital required to be maintained by the Lender with respect to the Obligations and the LOC Obligations and the Lender determines (in its sole and absolute discretion) that the rate of return on its capital as a consequence of such change in Applicable Law is reduced to a level below that which the Lender could have achieved but for the occurrence of such change in Applicable

11

Law, then, in such case upon notice from time to time by the Lender to the Borrower, the Borrower shall, within five (5) Business Days after receipt of notice from the Lender, pay directly to the Lender additional amounts sufficient to compensate the Lender for such reduction in rate of return with respect to the Obligations and LOC Obligations; provided, however, that the Lender shall use reasonable efforts to mitigate or limit the effect on the Borrower of any change in Applicable Law subject to this Section 3.6, including, if applicable, transferring or assigning the LOC Documents and LOC Commitment to a different office or branch of the Lender.  A statement of the Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the Borrower.  In determining such amount, the Lender may use any method of averaging and attribution, in accordance with GAAP, that it (in its sole and absolute discretion) shall deem applicable.

Section 3.7             Taxes.  All payments by the Borrower of principal of, and interest on, Revolving Credit Loans and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes, taxes imposed on or measured by the Lender’s net income, receipts or capital, and any branch profits taxes (such non-excluded items being called “Taxes”).  In the event that any withholding or deduction from any payment to be made by the Borrower hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrower will:

(a)           pay directly to the relevant authority the full amount required to be so withheld or deducted;

(b)           promptly forward to the Lender an official receipt or other documentation satisfactory to the Lender evidencing such payment to such authority; and

(c)           pay to the Lender such additional amount or amounts, if any, as is necessary to ensure that the net amount actually received by the Lender will equal the full amount the Lender would have received had no such withholding or deduction been required.

Moreover, if any Taxes are directly asserted against the Lender with respect to any payment received by the Lender hereunder, the Lender may pay such Taxes and the Borrower will within five (5) Business Days after receipt from the Lender of notice of such direct assertion (accompanied by reasonable documentation of such assertion) pay such additional amount (including any penalties, interest or expenses) as is necessary in order that the net amount received by the Lender after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount the Lender would have received had not such Taxes been asserted.

If the Borrower fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Lender the required receipts or other required documentary evidence, the Borrower shall indemnify the Lender for any incremental Taxes, interest or penalties that may become payable by the Lender as a result of any such failure.

Section 3.8             Security.  The Obligations of the Borrower shall be secured by the Collateral as provided in the Security Documents.

Section 3.9             Fees.

(a)           Letter of Credit Fees.  In consideration of the LOC Commitment, the Borrower agrees to pay to the Lender a fee (the “Letter of Credit Fee”) equal to one percent (1%) of (i) the face amount of

12

each Letter of Credit upon the date of issuance and any renewal thereof (except that the fee upon issuance shall not apply to Existing Letters of Credit, other than as to any renewal thereof), or (ii) the amount of any increase in the face value of any Letter of Credit.

(b)           Lender Fees.  In addition to the Letter of Credit Fees payable pursuant to subsection (a) hereof, the Borrower shall pay to the Lender the following fees: (i) a Letter of Credit application fee (provided that such application fee shall not apply to Existing Letters of Credit other than as to any renewal thereof); (ii) a Letter of Credit amendment fee; and (iii) courier fees, for each instance in which the Lender reasonably requires the use of courier services to perform its obligations pursuant hereto; provided, however, that the amount charged by the Lender with respect to the foregoing fees shall not exceed the reasonable and customary amounts that the Lender charges to its other customers for the same services.

(c)           Existing Fees.  Any fees which have accrued in respect of any Existing Letters of Credit and remain unpaid as of the Closing Date shall be payable upon the Closing Date.

Section 11.2           Lender’s Office.  The Lender hereby designates its office located at the address set forth in Section 11.1, or any subsequent office which shall have been specified for such purpose by written notice to the Borrower, as the Lender’s Office referred to herein.

Section 11.3           Expenses; Indemnity; Release of Claims.

(a)           Except as otherwise provided in this Agreement, the Borrower will (a) pay all reasonable out-of-pocket expenses of the Lender in connection with (i) the preparation, execution and delivery of this Agreement and each other Loan Document, whenever the same shall be executed and delivered, and (ii) the preparation, execution and delivery of any waiver, amendment or consent by the Lender relating to this Agreement or any other Loan Document or in connection with any field audit, including reasonable fees and disbursements of  legal counsel to the Lender, (b) pay all reasonable out-of-pocket expenses of the Lender actually incurred in connection with any enforcement of any rights and remedies of the Lender under this Agreement after a Default, including consulting with appraisers, accountants, attorneys and other Persons concerning the nature, scope or value of any right or remedy of the Lender hereunder or under any other Loan Document or any factual matters in connection therewith, which expenses shall include the reasonable fees and disbursements of such Persons, provided, however, that while no Event of

27

Default exists, the Borrower shall not be required to reimburse the Lender for the costs and expenses of any appraisers, accountants, attorneys and other Persons, unless the Borrower was given notice by the Lender prior to retaining such appraiser, accountant, engineer, attorney or other Persons, and (c) defend, indemnify and hold harmless the Lender, and its Affiliates, employees, agents, officers and directors, from and against any losses, penalties, fines, liabilities, settlements, damages, costs and expenses, suffered by any such Person in connection with any claim, investigation, litigation or other proceeding (whether or not the Lender is a party thereto) and the prosecution and defense thereof, arising out of or in any way connected with the Agreement, any other Loan Document or the Revolving Credit Loan, including reasonable attorneys’ and consultants’ 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.  The Borrower does hereby (i) waive any claim in tort, contract or otherwise which the Borrower may have against the Lender or any of its Affiliates or their officers, directors, agents, or employees (collectively, “Lender Agents”) arising in connection with the transactions contemplated hereby and out of the relationship between the Borrower and or any such Person prior to the Closing Date; and (ii) absolutely and unconditionally releases and discharges the Lender, each of its Affiliates and the Lender Agents from any and all claims, causes of action, losses, damages or expenses arising in connection with the transactions contemplated hereby and out of any relationship between it and the Lender, any such Affiliate or the Lender Agents which the Borrower may have as of the Closing Date; provided, however, that the foregoing waiver, release and discharge shall not apply with respect to any claim against the Lender or the Lender Agents arising out of the gross negligence, fraud or willful misconduct of the Lender or the Lender Agents.  Borrower acknowledges that it makes this waiver and release knowingly, voluntarily and only after considering the ramifications of this waiver and release with its legal counsel.

(b)           The Lender shall promptly notify the Borrower of any claim under this Section 11.3.  The Borrower may elect to assume the defense of any action, proceeding or dispute with a third party in respect of which a claim is to be made under this Section 11.3; provided, however, that if the Borrower assumes control of the defense of any such action, proceeding or dispute, the Borrower shall not agree or conclude any settlement that affects the Lender in any material respect without the prior written approval of the Lender (such approval not to be unreasonably withheld or delayed).  In the event the Borrower assumes control of the defense of any such action, proceeding or dispute, the Borrower shall not be liable to the Lender for any legal fees and expenses of additional counsel incurred by the Lender in connection with such defense; provided, however, that the Lender shall (at its own expense) have the right to employ its own counsel whose reasonable legal fees and expenses shall be indemnified by the Borrower if (i) there is or could reasonably be expected to be a conflict of interest between the Lender and the Borrower in connection with the defense of such action, proceeding or dispute, or (ii) there is a specific defense available to the Lender that is different from or additional to those available to the Borrower.

Section 11.4           Set-off.  In addition to any rights now or hereafter granted under Applicable Law, and not by way of limitation of any such rights, the Lender is hereby authorized by the Borrower at any time or from time to time, with notice to the Borrower, to set off and to appropriate and to apply any and all deposits (general or special, time or demand, including indebtedness evidenced by certificates of deposit, whether matured or unmatured) and any other indebtedness at any time held or owing by the Lender, or any such assignee to or for the credit or the account of the Borrower against and on account of the Obligations.

Section 11.5           Governing Law.  This Agreement, the Revolving Credit Note and the other Loan Documents, unless otherwise expressly set forth herein or therein, shall be governed by and construed and enforced in accordance with the laws of the State of Connecticut, without reference to the conflicts or choice of law principles thereof.

28

Section 11.6           Consent to Jurisdiction; Service of Process.

(a)           Borrower hereby irrevocably consents to the personal jurisdiction of the state and federal courts located in the State of Connecticut, in any action, claim or other proceeding arising out of any dispute in connection with this Agreement, the Revolving Credit Note and the other Loan Documents, any rights or obligations hereunder or thereunder, or the performance of such rights and obligations.  The Borrower hereby irrevocably appoints any Responsible Officer of the Borrower as its attorney upon whom may be served any summons, complaint or other process or pleading in any action, claim or proceeding brought by the Lender in connection with this Agreement, the Revolving Credit Note or the other Loan Documents, any rights or obligations hereunder or thereunder, or the performance of such rights and obligations, on behalf of itself or its property, in the manner specified in Section 11.1.  Nothing in this Section 11.6 shall affect the right of the Lender to serve legal process in any other manner permitted by Applicable Law or affect the right of the Lender to bring any action or proceeding against Borrower or its properties in the courts of any other jurisdictions.

(b)           To the extent that Borrower has or hereafter may acquire:  (i) any immunity from jurisdiction of the state or federal courts located in the State of Connecticut or from any legal process out of any such court (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, or (ii) any objection to the laying of the venue or of an inconvenient forum or any suit, action or proceeding brought in a state or federal court located in the State of Connecticut under process served in accordance with this Agreement or any Loan Document, Borrower hereby irrevocably waives such immunity or objection in respect of any suit, action or proceeding arising out of or relating to this Agreement or any Loan Document.

Section 11.7           Waiver of Jury Trial; Commercial Waiver; Preservation of Remedies.

(a)           WAIVER OF JURY TRIAL.  THE BORROWER IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING HEREAFTER INSTITUTED BY OR AGAINST BORROWER IN RESPECT OF ANY LETTER OF CREDIT, THIS AGREEMENT, ANY OTHER LOAN DOCUMENTS, OR ANY COLLATERAL.

(c)           Preservation of Certain Remedies.  The parties hereto and to the other Loan Documents preserve, without diminution, certain remedies that such Persons may employ or exercise freely, either alone, in conjunction with or during any dispute, claim or controversy arising out of, connected with or relating to the Revolving Credit Note or any other Loan Documents (“Dispute”) between or among parties to the Revolving Credit Note or any other Loan Document.  Each such Person shall have and hereby reserves the right to proceed in any court of proper jurisdiction or by self help to exercise or

29

prosecute the following remedies: (i) all rights to foreclose against any real or personal property or other security by exercising a power of sale granted in the Loan Documents or under applicable law or by judicial foreclosure and sale, (ii) all rights of self help including peaceful occupation of property and collection of rents, set off, and peaceful possession of property, (iii) obtaining provisional or ancillary remedies including injunctive relief, sequestration, garnishment, attachment, appointment of receiver and in filing an involuntary bankruptcy proceeding, and (iv) when applicable, a judgment by confession of judgment.  Preservation of these remedies does not limit the power of any court of proper jurisdiction to grant similar remedies that may be requested by a party in a Dispute.

Section 11.8           Reversal of Payments.  To the extent the Borrower makes a payment or payments to the Lender or the Lender receives any payment or proceeds of the Collateral which payments or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any Debtor Relief Law, state or federal law, common law or equitable cause, then, to the extent of such payment or proceeds repaid, the Obligations or part thereof intended to be satisfied shall be revived and continued in full force and effect as if such payment or proceeds had not been received by the Lender.

Section 11.9           Punitive Damages.  The Borrower recognizes that, in the event the Borrower fail to perform, observe or the Lender and the Borrower hereby agrees that no such Person shall have a remedy of punitive or exemplary damages against any other party to a Loan Document and each such Person hereby waives any right or claim to punitive or exemplary damages that it may now have or may arise in the future in connection with any Dispute, whether such Dispute is resolved through arbitration or judicially.

Section 11.10         Amendments, Waivers and Consents.  No amendment, modification or supplement to any provision of this Agreement or the other Loan Documents shall be effective unless the same shall be in writing and signed by the Borrower and the Lender.  No consent or waiver required to be granted by the Lender shall be effective unless in writing signed by the Lender.

Section 11.11         Agreement Controls.  In the event there is a conflict or inconsistency between this Agreement and any other Loan Document, the terms of this Agreement shall control; provided, that any provision of the Security Documents which imposes additional burdens on the Borrower or further restrict the rights of the Borrower or gives the Lender or Lenders additional rights shall not be deemed to be in conflict or inconsistent with this Agreement and shall be given full force and effect.

Section 11.12         Survival.  Notwithstanding any termination of this Agreement, the indemnities to which the Lender are entitled under the provisions of this Article X and any other provisions of this Agreement and the Loan Documents shall continue in full force and effect and shall protect the Lender against events arising after such termination as well as before.

Section 11.13         Counterparts.  This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and shall be binding upon all parties, their successors and assigns, and all of which taken together shall constitute one and the same agreement.

Section 11.14         Headings.  Titles and captions of Articles, Sections and subsections in this Agreement are for convenience only, and neither limit nor amplify the provisions of this Agreement.

Section 11.15         Severability.  Any provision of this Agreement or any other Loan Document which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remainder of such provision

30

or the remaining provisions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

Section 11.16         Entirety.  This Agreement together with the other Loan Documents represents the entire agreement of the parties hereto with respect to the subject matter hereof, and supersedes all prior agreements and understandings, oral and written, if any, including the Interim Agreement and any commitment letters or correspondence relating  to the Loan Documents or the transactions contemplated herein or therein.
