2. THE REVOLVING CREDIT FACILITY.

Subject to the terms and conditions set forth in this Credit Agreement, the Lender agrees to lend to the Borrower and the Borrower may borrow, repay, and reborrow from time to time from the Closing Date up to but not including the Loan Maturity Date upon notice by the Borrower to the Lender given in accordance with §2.6, such sums as are requested by the Borrower up to a maximum aggregate principal amount outstanding (after giving effect to all amounts requested) at any one time equal to the Total Commitment, minus the Maximum Drawing Amount and all Unpaid Reimbursement Obligations, provided that the sum of the outstanding amount of the Loans (after giving effect to all amounts requested) plus the Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not at any time exceed the Total Commitment. Each request for a Loan hereunder shall constitute a representation and warranty by the Borrower that the conditions set forth in §11 and §12, in the case of the initial Loans to be made on the Closing Date, and §12, in the case of all other Loans, have been satisfied on the date of such request.

2.2. Commitment Fee. The Borrower agrees to pay to the Lender a commitment fee (the “Commitment Fee”) calculated as set forth below on the average daily amount during each calendar

13

quarter or portion thereof from the date hereof to the Loan Maturity Date by which the Total Commitment minus the sum of the Maximum Drawing Amount and all Unpaid Reimbursement Obligations exceeds the outstanding amount of Loans during such calendar quarter. The Commitment Fee shall be calculated at the rate set forth below opposite the Borrower’s Funded Debt to EBITDA Ratio as of the last day of such calendar quarter:

Funded Debt to EBITDA Ratio	Commitment Fee
> 1.75:1.00	0.300	%
1.25:1.00 to < 1.75:1.00	0.250	%
0.75:1.00 to < 1.25:1.00	0.200	%
< .75:1.00	0.150	%

The Commitment Fee shall be payable quarterly in arrears on the 45th day of each calendar quarter for the immediately preceding calendar quarter commencing on the first such date following the date hereof, with a final payment on the Loan Maturity Date or any earlier date on which the Total Commitment shall terminate.

2.3. Reduction of Total Commitment. The Borrower shall have the right at any time and from time to time upon five (5) days prior written notice to the Lender, without any penalty or premium, to reduce by $5,000,000 or any integral multiple of $1,000,000 in excess thereof or terminate entirely the Total Commitment. Upon the effective date of any such reduction or termination, the Borrower shall pay to the Lender the full amount of any Commitment Fee then accrued on the amount of the reduction. No reduction or termination of the Total Commitment may be reinstated.

2.4. The Revolving Credit Note. The Loans shall be evidenced by a promissory note of the Borrower in substantially the form of Exhibit A hereto (the “Revolving Credit Note”), dated as of the Closing Date and completed with appropriate insertions. The Revolving Credit Note shall be payable to the order of the Lender in a principal amount equal to the Total Commitment or, if less, the outstanding amount of all Loans made by the Lender, plus interest accrued thereon, as set forth below. The Borrower irrevocably authorizes the Lender to make or cause to be made, at or about the time of the Drawdown Date of any Loan or at the time of receipt of any payment of principal on the Revolving Credit Note, an appropriate notation reflecting the making of such Loan or (as the case may be) the receipt of such payment.

2.5. Interest on Loans. Except as otherwise provided in §5.10, interest on the outstanding principal amount of any Loan when classified as a: (i) LIBOR Rate Loan shall accrue during each Interest Period at a rate equal to the sum of the LIBOR Lending Rate for such Interest Period plus the Applicable Margin thereto and be payable on each Interest Payment Date, (ii) LIBOR-Reference Banks Rate Loan shall accrue during each Interest Period at a rate equal to the sum of the LIBOR-Reference Banks Lending Rate for such Interest Period plus the Applicable Margin thereto and be payable on each Interest Payment Date, (iii) LIBOR Advantage Loan shall accrue during each Interest Period at a rate equal to the sum of the LIBOR Rate for such Interest Period plus the Applicable Margin thereto and be payable on each Interest Payment Date and (iv) Prime Rate Loan shall accrue during each Interest Period at a rate equal to the Prime Rate and be payable on each Interest Payment Date. The Borrower promises to pay interest on each Loan in arrears on each Interest Payment Date with respect thereto.

2.6. Requests for Loans. The Borrower shall give to the Lender written notice (or telephonic notice confirmed in writing) of each Loan requested hereunder no less than one (1) Business Day prior to the proposed Drawdown Date of any Prime Rate Loan. Each such notice shall specify (i)

14

the principal amount of the Prime Rate Loan requested, (ii) the proposed Drawdown Date of such Prime Rate Loan and (iii) the Interest Period for such Loan. By delivering a borrowing request to the Lender on or before 10:00 a.m., New York time, on a Business Day, the Borrower may from time to time irrevocably request, on not less than two nor more than five Business Days’ notice, that a LIBOR Rate Loan or a LIBOR Advantage Loan be made in a minimum amount of $500,000 and integral multiples of $100,000, with an Interest Period of 30 days. On the terms and subject to the conditions of this Agreement, each LIBOR Rate Loan or LIBOR Advantage Loan shall be made available to the Borrower no later than 11:00 a.m. New York time on the first day of the applicable Interest Period by deposit to the account of the Borrower as shall have been specified in its borrowing request. The definitions of certain terms set forth on Schedule 1 hereto shall apply in lieu of the definitions set forth in §1.1 to any LIBOR Advantage Loan made hereunder. Each request for a Loan shall be irrevocable and binding on the Borrower and shall obligate the Borrower to accept the Loan requested from the Lender on the proposed Drawdown Date.

2.7. Conversion Options.

2.7.1. Continuation and Conversion Elections as to existing LIBOR Rate Loans. By delivering a continuation/conversion notice to the Lender on or before 10:00 a.m., New York time, on a Business Day, the Borrower may from time to time irrevocably elect, on not less than two nor more than five Business Days’ notice, that all, or any portion in an aggregate minimum amount of $500,000 and integral multiples of $100,000, of any LIBOR Rate Loan be converted on the last day of an Interest Period into a LIBOR Rate Loan with a different Interest Period, or continued on the last day of an Interest Period as a LIBOR Rate Loan with a similar Interest Period, or converted on the last day of an Interest Period into a Prime Rate Loan, provided, however, that no portion of the outstanding principal amount of any LIBOR Rate Loans may be converted to LIBOR Rate Loans when any Default or Event of Default shall have occurred and be continuing, and no portion of the outstanding principal amount of any LIBOR Rate Loans may be converted to LIBOR Rate Loans of a different duration if such LIBOR Rate Loans relate to any Hedging Obligations. If any Default or Event of Default shall have occurred and be continuing (if the Lender does not otherwise elect to exercise any right to accelerated the Loans that it is granted hereunder), or in the absence of delivery of a continuation/conversion notice with respect to any LIBOR Rate Loan at least two Business Days before the last day of the then current Interest Period with respect thereto, each maturing LIBOR Rate Loan shall automatically be continued as a Prime Rate Loan. On the date on which such conversion is being made the Lender shall take such action as is necessary to transfer such Loans to its Domestic Lending Office or its LIBOR Lending Office, as the case may be. Each request relating to the conversion of a Loan to a LIBOR Rate Loan or the continuation of a LIBOR Rate Loan shall be irrevocable by the Borrower.

2.7.2. Continuation and Conversion Elections regarding Prime Rate Loans. By delivering a conversion notice to the Lender on or before 10:00 a.m., New York time, on a Business Day, the Borrower may from time to time irrevocably elect, on not less than two nor more than five Business Days’ notice, that all, or any portion in an aggregate minimum amount of $500,000 and integral multiples of $100,000, of any Prime Rate Loan be converted on the last day of an Interest Period into a LIBOR Rate Loan, provided, however, that no portion of the outstanding principal amount of any Prime Rate Loans may be converted to LIBOR Rate Loans when any Default or Event of Default shall have occurred and be continuing.

15

2.8. Funds for Loans. Upon receipt of the documents required by §§11 and 12 and the satisfaction of the other conditions set forth therein, to the extent applicable, the Lender will make available to the Borrower the aggregate amount of such Loans.

3. REPAYMENT OF THE LOANS.

3.1. Maturity. The Borrower promises to pay on the Loan Maturity Date, and there shall become absolutely due and payable on the Loan Maturity Date, all of the Loans outstanding on such date, together with any and all accrued and unpaid interest thereon.

3.2. Mandatory Repayments of Loan. If at any time the sum of the outstanding amount of the Loans, the Maximum Drawing Amount and all Unpaid Reimbursement Obligations exceeds the Total Commitment at such time, then the Borrower shall immediately pay the amount of such excess to the Lender for application: first, to any Unpaid Reimbursement Obligations; second, to the Loans; and third, to provide to the Lender cash collateral for Reimbursement Obligations as contemplated by §4.2(b) and (c).

3.3. Optional Repayments of Loans.

3.3.1. General. The Borrower shall have the right, at its election, to repay the outstanding amount of the Loans, as a whole or in part, at any time without penalty or premium, provided that any full or partial prepayment of the outstanding amount of any LIBOR Rate Loans pursuant to this §3.3 must comply with the provisions of §3.3.2 hereof, but any LIBOR Advantage Loan may be prepaid, in whole or in part, at any time without penalty or premium. The Borrower shall give the Lender, no later than 10:00 a.m. (Boston time), on the Business Day on which the Borrower wishes to effect repayment pursuant to this §3.3 of Prime Rate Loans, specifying the proposed date of payment of such Loans and the principal amount to be paid. Each such partial prepayment of Prime Rate Loans shall be in a minimum principal amount of $500,000 and, if in excess of such amount, in an integral multiple of $100,000 in excess thereof, shall be accompanied by the payment of accrued interest on the principal repaid to the date of payment.

3.3.2. LIBOR Rate Loans. LIBOR Rate Loans may be prepaid upon the terms and conditions set forth herein. For LIBOR Rate Loans in connection with which the Borrower has or may incur Hedging Obligations, additional obligations may be associated with prepayment, in accordance with the terms and conditions of the applicable Hedging Contracts. The Borrower shall give the Lender, no later than 10:00 a.m., New York City time, at least two (2) Business Days notice of any proposed prepayment of any LIBOR Rate Loans, specifying the proposed date of payment of such LIBOR Rate Loans, and the principal amount to be paid. Each partial prepayment of the principal amount of LIBOR Rate Loans shall be in an integral multiple of $100,000 and accompanied by the payment of all charges outstanding on such LIBOR Rate Loans and of all accrued interest on the principal repaid to the date of payment. Borrower acknowledges that prepayment or acceleration of a LIBOR Rate Loan during an Interest Period may result in the Lender’s incurring additional costs, expenses and/or liabilities and that it is extremely difficult and impractical to ascertain the extent of such costs, expenses and/or liabilities. Therefore, all full or partial prepayments of LIBOR Rate Loans shall be accompanied by, and the Borrower hereby promises to pay, on each date a LIBOR Rate Loan is prepaid or the date all sums payable hereunder become due and payable, by acceleration or otherwise, in addition to all other sums then owing, an amount (“LIBOR Rate Loan Prepayment Fee”) determined by the Lender pursuant to the following formula:

(a) the then current rate for United States Treasury securities (bills on a discounted basis shall be converted to a bond equivalent) with a maturity date closest to the end of the Interest Period as to which prepayment is made, subtracted from

16

(b) the LIBOR Lending Rate plus the Applicable Margin applicable to the LIBOR Rate Loan being prepaid.

If the result of this calculation is zero or a negative number, then there shall be no LIBOR Rate Loan Prepayment Fee. If the result of this calculation is a positive number, then the resulting percentage shall be multiplied by the amount of the LIBOR Rate Loan being prepaid. The resulting amount shall be divided by:

(x) 360

and multiplied by:

(y) the number of days remaining in the Interest Period as to which the prepayment is being made.

Said amount shall be reduced to present value calculated by using the referenced United States Treasury securities rate and the number of days remaining on the Interest Period for the LIBOR Rate Loan being prepaid. The resulting amount of these calculations shall be the LIBOR Rate Loan Prepayment Fee.

4. LETTERS OF CREDIT.

4.1. Letter of Credit Commitments.

4.1.1. Commitment to Issue Letters of Credit. Subject to the terms and conditions hereof and the execution and delivery by the Borrower of a letter of credit application on the Lender’s customary form (a “Letter of Credit Application”), the Lender in reliance upon the representations and warranties of the Borrower contained herein, agrees to issue, extend and renew for the account of the Borrower one or more standby or documentary letters of credit (individually, a “Letter of Credit”), in such form as may be requested from time to time by the Borrower and agreed to by the Lender; provided, however, that, after giving effect to such request, (a) the sum of the aggregate Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not exceed $10,000,000 at any one time and (b) the Total Outstanding shall not exceed the Total Commitment at such time.

4.1.2. Letter of Credit Applications. Each Letter of Credit Application shall be completed to the reasonable satisfaction of the Lender.

4.1.3. Terms of Letters of Credit. Each Letter of Credit issued, extended or renewed hereunder shall, among other things, (a) provide for the payment of sight drafts for honor thereunder when presented in accordance with the terms thereof and when accompanied by the documents described therein, and (b) have an expiry date no later than the date which is fourteen (14) days prior to the Loan Maturity Date. Each Letter of Credit so issued, extended or renewed shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision),

17

International Chamber of Commerce Publication No. 500 or any successor version thereto adopted by the Lender in the ordinary course of its business as a letter of credit issuer and in effect at the time of issuance of such Letter of Credit (the “Uniform Customs”) or, in the case of a standby Letter of Credit, either the Uniform Customs or the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, or any successor code of standby letter of credit practices among banks adopted by the Lender in the ordinary course of its business as a standby letter of credit issuer and in effect at the time of issuance of such Letter of Credit.

4.2. Reimbursement Obligation of the Borrower. In order to induce the Lender to issue, extend and renew each Letter of Credit, the Borrower hereby agrees to reimburse or pay to the Lender, for the account of the Lender, with respect to each Letter of Credit issued, extended or renewed by the Lender hereunder, (a) except as otherwise expressly provided in §4.2(b) and (c), on each date that any draft presented under such Letter of Credit is honored by the Lender, or the Lender otherwise makes a payment with respect thereto, (i) the amount paid by the Lender under or with respect to such Letter of Credit, and (ii) the amount of any taxes, fees, charges or other costs and expenses whatsoever incurred by the Lender in connection with any payment made by the Lender under, or with respect to, such Letter of Credit, with each drawing under any Letter of Credit, unless otherwise directly reimbursed or paid by the Borrower, to constitute, automatically and without further action by the Borrower a request by the Borrower to the Lender for a borrowing pursuant to §2.6 of a Prime Rate Loan in the amount of such drawing, with the Drawdown Date with respect to such borrowing being the date of such drawing; (b) upon the reduction (but not termination) of the Total Commitment to an amount less than the Maximum Drawing Amount, an amount equal to such difference, which amount shall be held by the Lender as cash collateral for all Reimbursement Obligations, and (c) upon the termination of the Total Commitment, or the acceleration of the Reimbursement Obligations with respect to all Letters of Credit in accordance with §13, an amount equal to the then Maximum Drawing Amount on all Letters of Credit, which amount shall be held by the Lender in an interest bearing account as cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Lender at the Lender’s Office in immediately available funds. Interest on any and all amounts remaining unpaid by the Borrower under this §4.2 at any time from the date such amounts become due and payable (whether as stated in this §4.2, by acceleration or otherwise) until payment in full (whether before or after judgment) shall be payable to the Lender on demand at the rate specified in §5.10 for overdue principal on the Loans.

4.4. Obligations Absolute. The Borrower’s obligations under this §4 shall be absolute and unconditional under any and all circumstances and irrespective of the occurrence of any Default or Event of Default or any condition precedent whatsoever or any setoff, counterclaim or defense to payment which the Borrower may have or have had against the Lender or any beneficiary of a Letter of Credit. The Borrower further agrees with the Lender that the Lender shall not be responsible for, and the Borrower’s Reimbursement Obligations under §4.2 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, the beneficiary of any Letter of Credit or any financing institution or other party to which any Letter of Credit may be transferred or any claims or defenses whatsoever of the Borrower against the

18

beneficiary of any Letter of Credit or any such transferee. The Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit. The Borrower agrees that any action taken or omitted by the Lender under or in connection with each Letter of Credit and the related drafts and documents, if done in good faith, shall be binding upon the Borrower and shall not result in any liability on the part of the Lender to the Borrower. Nothing contained in this §4.4 or §4.5 shall in any manner limit or otherwise affect any claims the Borrower may have against the Lender arising from the gross negligence or willful misconduct of the Lender as the issuer of any Letter of Credit.

4.5. Reliance by Issuer. To the extent not inconsistent with §4.4, the Lender shall be entitled to rely, and shall be fully protected in relying upon, any Letter of Credit, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel, independent accountants and other experts selected by the Lender.

4.6. Letter of Credit Fee. The Borrower shall pay a fee (in each case, a “Letter of Credit Fee”) to the Lender in respect of each Letter of Credit in an amount equal to one and one-quarter percent (1.25%) per annum of the face amount of such Letter of Credit. Such Letter of Credit Fees shall be payable quarterly in arrears on the first day of the calendar quarter for the calendar quarter most recently ended. In respect of each Letter of Credit, the Borrower shall also pay to the Lender at such other time or times as such charges are customarily made by the Lender, the Lender’s customary issuance, amendment, negotiation or document examination and other administrative fees as in effect from time to time.

5. CERTAIN GENERAL PROVISIONS.

5.1. Closing Fee. The Borrower agrees to pay to the Lender on the Closing Date a closing fee of $100,000 (the “Closing Fee”).

5.2. Payments to Lender. All payments of principal, interest, Fees and any other amounts due hereunder or under any of the other Loan Documents shall be made on the due date thereof to the Lender in Dollars at the Lender’s Office or at such other place that the Lender may from time to time designate, in each case at or about 11:00 a.m. (Boston, Massachusetts, time or other local time at the place of payment) and in immediately available funds.

5.3. Computations. All computations of interest on the Loans and of Fees shall be based on a 360-day year and paid for the actual number of days elapsed. Except as otherwise provided in the definition of the term “Interest Period” with respect to LIBOR Rate Loans, whenever a payment hereunder or under any of the other Loan Documents becomes due on a day that is not a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and interest shall accrue during such extension. The outstanding amount of the Loans as reflected on the Records from time to time shall be prima facie evidence of the amounts owing thereunder.

5.4. LIBOR Rate Lending Unlawful. If the Lender shall determine (which determination shall, upon notice thereof to the Borrower be conclusive and binding on the Borrower) that the introduction of or any change in or in the interpretation of any law, rule, regulation or guideline, (whether or not having the force of law) makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for the Lender to make, continue or maintain any LIBOR Rate Loan as, or to convert any Loan into, a LIBOR Rate Loan of a certain duration, all LIBOR Rate Loans of such

19

type shall automatically convert into LIBOR-Reference Banks Loans at the end of the then current Interest Periods with respect thereto or sooner, if required by such law or assertion. For purposes of this Agreement, in the event of such a conversion, all LIBOR-Reference Banks Rate Loans shall be treated (except as to interest rate) as equivalent to a LIBOR Rate Loan of similar amount and Interest Period. For greater certainty, all provisions of this Agreement relating to LIBOR Rate Loans shall apply equally to LIBOR-Reference Banks Loans, including, but not limited to the manner in which LIBOR-Reference Banks For the avoidance of doubt, in the event of such conversion, all provisions under this Agreement relating to LIBOR Rate Loans shall apply to LIBOR-Reference Banks Loans, including, but not limited to the manner in which LIBOR Rate Loans are requested, continued, converted, the manner in which interest accrues, is payable, principal payments are made, whether voluntary or involuntary, as well as any penalties, increased costs or taxes associated with any of the foregoing.

5.5. Substitute Rate. If the Lender shall have determined that

(a) US dollar deposits in the relevant amount and for the relevant Interest Period are not available to the Lender in the London interbank market;

(b) by reason of circumstances affecting the Lender in the London interbank, adequate means do not exist for ascertaining the LIBOR Rate applicable hereunder to LIBOR Rate Loans of any duration, or

(c) LIBOR no longer adequately reflects the Lender’s cost of funding Loans,

then, upon notice from the Lender to the Borrower, all LIBOR Rate Loans shall automatically convert to LIBOR-Reference Banks Loans.

5.6. Indemnities. In addition to the LIBOR Rate Loan Prepayment Fee, the Borrower agrees to reimburse the Lender (without duplication) for any increase in the cost to the Lender, or reduction in the amount of any sum receivable by the Lender, in respect, or as a result of:

(a) any conversion or repayment or prepayment of the principal amount of any LIBOR Rate Loans on a date other than the scheduled last day of the Interest Period applicable thereto, whether pursuant to Section 5.6 or otherwise;

(b) any Loans not being made as LIBOR Rate Loans in accordance with the borrowing request thereof;

(c) any LIBOR Rate Loans not being continued as, or converted into, LIBOR Rate Loans in accordance with the continuation/conversion notice thereof, or

(d) any costs associated with marking to market any Hedging Obligations that (in the reasonable determination of the Lender) are required to be terminated as a result of any conversion, repayment or prepayment of the principal amount of any LIBOR Rate Loan on a date other than the scheduled last day of the Interest Period applicable thereto, whether pursuant to Section 3.3.2 or otherwise;

The Lender shall promptly notify the Borrower in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required fully to compensate the Lender for such increased cost or reduced amount. Such additional amounts shall be payable by the Borrower to the Lender within five days of its receipt of such notice, and such notice shall, in the absence of manifest error, be conclusive and binding on the Borrower. The Borrower understands, agrees and

20

acknowledges the following: (i) the Lender does not have any obligation to purchase, sell and/or match funds in connection with the use of LIBOR Rate as a basis for calculating the rate of interest on a LIBOR Rate Loan, (ii) the LIBOR Rate may be used merely as a reference in determining such rate, and (iii) the Borrower has accepted the LIBOR Rate as a reasonable and fair basis for calculating such rate, the LIBOR Rate Prepayment Fee, and other funding losses incurred by the Lender. Borrower further agrees to pay the LIBOR Rate Prepayment Fee and other funding losses, if any, whether or not the Lender elects to purchase, sell and/or match funds.

5.7. Increased Costs. If on or after the date hereof the adoption of any applicable law, rule or regulation or guideline (whether or not having the force of law), or any change therein, 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 authority, central bank or comparable agency:

(a) shall subject the Lender to any tax, duty or other charge with respect to its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans, or shall change the basis of taxation of payments to the Lender of the principal of or interest on its LIBOR Rate Loans or any other amounts due under this agreement in respect of its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans (except for the introduction of, or change in the rate of, tax on the overall net income of the Lender or franchise taxes, imposed by the jurisdiction (or any political subdivision or taxing authority thereof) under the laws of which the Lender is organized or in which the Lender’s principal executive offices are located); or

(b) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System of the United States) against assets of, deposits with or for the account of, or credit extended by, the Lender or shall impose on the Lender or on the London interbank market any other condition affecting its LIBOR Rate Loans or its obligation to make LIBOR Rate Loans;

and the result of any of the foregoing is to increase the cost to the Lender of making or maintaining any LIBOR Rate Loan, or to reduce the amount of any sum received or receivable by the Lender under this Agreement with respect thereto, by an amount deemed by the Lender to be material, then, within 15 days after demand by the Lender, the Borrower shall pay to the Lender such additional amount or amounts as will compensate the Lender for such increased cost or reduction; provided that the Borrower shall be liable for such costs with respect to a period prior to the date of notice from the Lender of the likely incurrence of such costs of no more than sixty (60) days. 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.

5.8. Increased Capital Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by the Lender, or persons controlling the Lender, and the Lender determines (in its sole and absolute discretion) that the rate of return on its or such controlling person’s capital as a consequence of its commitments to make Loans hereunder or the Loans made by the Lender are reduced to a level below that which the Lender or such controlling persons could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by the Lender to the Borrower, the Borrower shall immediately pay directly to the Lender additional amounts sufficient to compensate the Lender or such controlling persons for such reduction in rate of return; provided that the Borrower

21

shall be liable for such costs with respect to a period prior to the date of notice from the Lender of the likely incurrence of such costs of no more than sixty (60) days. 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 that it (in its sole and absolute discretion) shall deem applicable.

5.9. Taxes. All payments by the Borrower of principal of, and interest on, the LIBOR Rate 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 and taxes imposed on or measured by the Lender’s net income or receipts (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 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 promptly 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. 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.

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.

5.10. Interest After Default. During the continuance of an Event of Default the principal of the Loans shall, until such Event of Default has been cured or remedied or such Event of Default has been waived by the Lender, bear interest at a rate per annum equal to four percent (4%) above the rate of interest otherwise applicable to such Loans pursuant to §2.5 (or if no rate of interest is then applicable thereto, the Prime Rate).

6. SECURITY ARRANGEMENTS.

6.1. Equity Pledge. The payment and performance of the Obligations shall be secured by the pledge by Borrower of all equity securities of each Domestic Subsidiary and 65% of the equity securities of each Foreign Subsidiary that is or becomes a Material Subsidiary.

22

6.2. Guarantees of Subsidiaries. The payment and performance of the Obligations shall be guaranteed by each Guarantor pursuant to the terms of the Guarantees.

7.15. Employee Benefit Plans.

7.15.1. In General. Each Employee Benefit Plan and each Guaranteed Pension Plan has been maintained and operated in compliance in all material respects with the provisions of ERISA and all Applicable Pension Legislation and, to the extent applicable, the Code, including but not limited to the provisions thereunder respecting prohibited transactions and the bonding of fiduciaries and other persons handling plan funds as required by §412 of ERISA. The Borrower has heretofore delivered to the Lender the most recently completed annual report, Form 5500, with all required attachments, and actuarial statement required to be submitted under §103(d) of ERISA, with respect to each Guaranteed Pension Plan.

7.15.2. Terminability of Welfare Plans. No Employee Benefit Plan, which is an employee welfare benefit plan within the meaning of §3(1) or §3(2)(B) of ERISA, provides benefit coverage subsequent to termination of employment, except as required by Title I, Part 6 of ERISA or the applicable state insurance laws and except for continuing medical benefits provided under any severance policy of the Borrower and/or any Subsidiary. The Borrower may terminate each such Plan at any time (or at any time subsequent to the expiration of any applicable bargaining agreement) in the discretion of the Borrower without liability to any Person other than for claims arising prior to termination.

7.15.3. Guaranteed Pension Plans. Each contribution required to be made to a Guaranteed Pension Plan, whether required to be made to avoid the incurrence of an accumulated funding deficiency, the notice or lien provisions of §302(f) of ERISA, or otherwise, has been timely made. No waiver of an accumulated funding deficiency or extension of amortization periods has been received with respect to any Guaranteed Pension Plan, and neither the Borrower nor any ERISA Affiliate is obligated to or has posted security in connection with an amendment to a Guaranteed Pension Plan pursuant to §307 of ERISA or §401(a)(29) of the Code. No liability to the PBGC (other than required insurance premiums, all of which have been paid) has been incurred by the Borrower or any ERISA Affiliate with respect to any Guaranteed Pension Plan and there has not been any ERISA Reportable Event (other than an ERISA Reportable Event as to which the requirement of thirty (30) days notice has been waived), or any other event or condition which presents a material risk of termination of any Guaranteed Pension Plan by the PBGC. Based on the latest valuation of each Guaranteed Pension Plan (which in each case occurred within twelve months of the date of this representation), and on the actuarial methods and assumptions employed for that valuation, the aggregate benefit liabilities of all such Guaranteed Pension Plans within the meaning of §4001 of ERISA did not exceed the aggregate value of the assets of all such Guaranteed Pension Plans, disregarding for this purpose the benefit liabilities and assets of any Guaranteed Pension Plan with assets in excess of benefit liabilities.

7.15.4. Multiemployer Plans. Neither the Borrower nor any ERISA Affiliate has incurred any material liability (including secondary liability) to any Multiemployer Plan as a result of a complete or partial withdrawal from such Multiemployer Plan under §4201 of ERISA or as a result of a sale of assets described in §4204 of ERISA. Neither the Borrower nor any ERISA Affiliate has been notified that any Multiemployer Plan is in reorganization or insolvent under and within the meaning of §4241 or §4245 of ERISA or is at risk of entering reorganization

26

or becoming insolvent, or that any Multiemployer Plan intends to terminate or has been terminated under §4041A of ERISA.

7.16. Use of Proceeds.

7.16.1. General. The proceeds of the Loans shall be used for working capital and general corporate purposes, including, without limitation, financing all or a portion of a Standard Permitted Acquisition, a Special Permitted Acquisition and other Investments permitted by §9.3 hereof other than the purchase or carrying of any “margin security” or “margin stock” as defined in §7.16.2 hereof in violation of law. The Borrower will obtain Letters of Credit solely for working capital and general corporate purposes.

7.16.2. Regulations U and X. No portion of any Loans is to be used, and no portion of any Letter of Credit is to be obtained, for the purpose of purchasing or carrying any “margin security” or “margin stock” (as such terms are used in Regulations U and X of the Board of Governors of the Federal Reserve System, 12 C.F.R. Parts 221 and 224) in violation of law.

7.17. Environmental Compliance. As to the past and present condition and usage of the Real Estate owned by the Borrower or its Subsidiaries (the “Owned Real Estate”) and the operations conducted thereon and as to the condition and usage of the Real Estate leased by the Borrower or its Subsidiaries (the “Leased Real Estate”) and the operations conducted thereon, the Borrower represents and warrants that:

(a) None of the Borrower and its Subsidiaries, any operator of the Owned Real Estate or any operator of the Leased Real Estate (but, in the case of Leased Real Estate, only if the Borrower or any Subsidiary could reasonably be expected to have any liability as a result of leasing such Real Estate) or any operations thereon is in violation, or alleged violation, of any judgment, decree, order, law, license, rule or regulation pertaining to environmental matters, including without limitation, those arising under the Resource Conservation and Recovery Act (“RCRA”), the Comprehensive Environmental Response, Compensation and Liability Act of 1980 as amended (“CERCLA”), the Superfund Amendments and Reauthorization Act of 1986 (“SARA”), the Federal Clean Water Act, the Federal Clean Air Act, the Toxic Substances Control Act, or any state, local or foreign law, statute, regulation, ordinance, order or decree relating to health, safety or the environment (hereinafter “Environmental Laws”), which violation in each case would have a Material Adverse Effect;

(b) Neither the Borrower nor any of its Subsidiaries has received written notice from any third party including, without limitation, any Governmental Authority, (i) that any one of them has been identified by the United States Environmental Protection Agency (“EPA”) as a potentially responsible party under CERCLA with respect to a site listed on the National Priorities List, 40 C.F.R. Part 300 Appendix B; (ii) that any hazardous waste, as defined by 42 U.S.C. §6903(5), any hazardous substances as defined by 42 U.S.C. §9601(14), any pollutant or contaminant as defined by 42 U.S.C. §9601(33) and any toxic substances, oil or hazardous materials or other chemicals or substances regulated by any Environmental Laws (“Hazardous Substances”) which any one of them has generated, transported or disposed of has been found at any site at which a Governmental Authority has conducted or has ordered that the Borrower or any of its Subsidiaries conduct a remedial investigation, removal or other response action pursuant to any Environmental Law; or (iii) that it is or shall be a named party to any claim, action, cause of action, complaint, or legal or administrative proceeding (in each case, contingent or otherwise) arising out of any third party’s incurrence of costs, expenses, losses or damages of

The foregoing notwithstanding, the Borrower’s aggregate Investments in New Domestic Subsidiaries that shall not individually be deemed Special Material Subsidiaries shall not exceed $20,000,000 (the “Special Limit”), provided, that if such Investments shall exceed the Special Limit, the Borrower shall promptly designate such additional New Domestic Subsidiaries to be deemed “Special Material Subsidiaries” as necessary in order to adhere to the Special Limit.

48

COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF THE LENDER RELATING TO THE ADMINISTRATION OF THE LOANS OR ENFORCEMENT OF THE LOAN DOCUMENTS AND AGREES THAT IT WILL NOT SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.

This Note evidences borrowings under and has been issued by the Borrower in accordance with the terms of the Credit Agreement. The Lender and any holder hereof is entitled to the benefits of the Credit Agreement and the other Loan Documents, and may enforce the agreements of the Borrower contained therein, and any holder hereof may exercise the remedies provided for thereby or otherwise available in respect thereof, all in accordance with the terms thereof.

The outstanding amount of the Revolving Credit Loans set forth in such record, including computer records, maintained by the Lender with respect to any Revolving Credit Loans shall be prima facie evidence of the principal amount thereof owing and unpaid to the Lender, but the failure to record, or any error in so recording, any such amount in any such record shall not limit or otherwise affect the obligation of the Borrower hereunder or under the Credit Agreement to make payments of principal of and interest on this Revolving Credit Note when due.

The Borrower has the right in certain circumstances and the obligation under certain other circumstances to prepay the whole or part of the principal of this Resolving Credit Note on the terms and conditions specified in the Credit Agreement.

If any one or more Events of Default shall occur, the entire unpaid principal amount of this Note and all of the unpaid interest accrued thereon may become or be declared due and payable in the manner and with the effect provided in the Credit Agreement.

The Borrower will pay on demand all attorneys’ reasonable fees and out-of-pocket expenses incurred by the Lender in the administration of all liabilities and obligations of the Borrower to the Lender, including, without limitation, costs and expenses associated with travel on behalf of the Lender. The Borrower will also pay on demand, without limitation, all

attorneys’ reasonable fees, out-of-pocket expenses incurred by the Lender’s attorneys and all costs incurred by the Lender, including, without limitation costs and expenses associated with travel on behalf of the Lender, which costs and expenses are directly or indirectly related to the protection or enforcement of any of the Lender’s rights against the Borrower or any such endorser or guarantor to the Lender (whether or not suit is instituted by or against the Lender).

No delay or omission on the part of the Lender in exercising any right hereunder shall operate as a waiver of such right or of any other right of the Lender, nor shall any delay, omission or waiver on any one occasion be deemed a bar to or waiver of the same or any other right on any future occasion.

Except as required by law or as otherwise provided in the Credit Agreement or any other Loan Document, the Borrower and each endorser and guarantor of this Note waive presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement hereof and also waive any delay on the part of the Lender. Each assents to any extension or other indulgence (including, without limitation, the release or substitution of collateral) permitted the Borrower or any such endorser or guarantor by the Lender with respect to this Note and/or any collateral given to secure this Note and/or any other liability of the Borrower or such endorser or guarantor to the Lender, and no such discharge or release of any other party primarily or secondarily liable hereon shall discharge or otherwise affect the liability of the Borrower or any such endorser or guarantor to the Lender.

None of the terms or provisions of this Note may be excluded, modified, or amended except by a written instrument duly executed on behalf of the Borrower expressly referring hereto and setting forth the provision so excluded, modified or amended.

This Note shall be binding upon the Borrower and each endorser and guarantor hereof and upon their heirs, successors and representatives, and shall inure to the benefit of the Lender and its successors, endorsees and assigns.

The liabilities of the Borrower and any endorser or guarantor of this Note are joint and several. No person obligated on account of this Note may seek contribution from any other person also obligated unless and until all liabilities to the Lender of the person from whom contribution is sought have been satisfied in full.

THIS NOTE IS DELIVERED TO THE LENDER AT ITS PRINCIPAL OFFICE IN BOSTON, MASSACHUSETTS, SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS, WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAWS AND SHALL TAKE EFFECT AS A SEALED INSTRUMENT. THE BORROWER AND EACH ENDORSER AND GUARANTOR OF THIS NOTE SUBMIT TO THE JURISDICTION OF THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS AND OF THE UNITED STATES DISTRICT COURTS SITUATED THEREIN FOR ALL PURPOSES WITH RESPECT TO THIS NOTE, ANY COLLATERAL GIVEN TO SECURE THEIR RESPECTIVE LIABILITIES TO THE LENDER, AND THEIR RESPECTIVE RELATIONSHIPS WITH THE LENDER.

EXHIBIT D

SUBSIDIARY GUARANTY

This Subsidiary Guaranty (the “Guaranty”) is made as of the              day of June, 2006, by                         , a                      corporation (the “Guarantor”), to Citizens Bank of Massachusetts (the “Lender”) with respect to obligations of Kronos Incorporated, a Massachusetts corporation and the ultimate parent of the Guarantor (the “Borrower”).

Whereas, the Lender has extended credit to the Borrower under the terms of the Revolving Credit Agreement, dated as of the date hereof, between the Borrower and the Lender (as amended, the “Credit Agreement”);

Whereas, the Borrower and the Guarantor are members of a group of related corporations, the success of any one of which is dependent in part on the success of the other members of such group;

Whereas, the Guarantor expects to receive substantial direct benefits from the extensions of credit to the Borrower by the Lender pursuant to the Credit Agreement;

Whereas, the Borrower has covenanted under the Credit Agreement to cause any Material Subsidiary to execute and deliver a guaranty of the Borrower’s obligations to the Lender under the Credit Agreement and the Guarantor is a Material Subsidiary; and

Whereas, the Guarantor wishes to guaranty the Borrower’s obligations to the Lender under the Credit Agreement as provided herein;

Now therefore, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Guarantor covenants and agrees as follows:

1. Guaranty of Payment and Performance. The Guarantor hereby guarantees to the Lender the full and punctual payment when due (whether at maturity, by required pre-payment, by acceleration or otherwise), as well as the performance, of all of the Obligations (as defined in the Credit Agreement), including all such that would become due but for the operation of the automatic stay pursuant to Section 362(a) of the Federal Bankruptcy Code and the operation of Sections 502(b) and 506(b) of the Federal Bankruptcy Code, together with all costs of collection, compromise or enforcement, including without limitation reasonable attorneys’ fees, incurred with respect to the Obligations or this Guaranty, or with respect to a proceeding under the federal bankruptcy laws or any insolvency, receivership, arrangement or reorganization law or an assignment for the benefit of creditors concerning Borrower or Guarantor, together with interest on all such costs of collection, compromise or enforcement from the date arising at the rate of interest for overdue principal set forth in the Credit Agreement (all the foregoing, collectively, the “Guaranty Obligations”). This Guaranty is an absolute, unconditional and continuing guaranty of the full and punctual payment and performance of the Guaranty Obligations and not of their collectibility only and is in no way conditioned upon any requirement that the Lender first attempt to collect any of the Guaranty Obligations from the Borrower or resort to any security or other means of obtaining their payment. Should the Borrower default in the payment or performance of any of the Obligations, the obligations of the Guarantor hereunder shall become immediately due and payable to the Lender, without demand or notice of any nature, all

of which are expressly waived by the Guarantor. Payments by the Guarantor hereunder may be required by the Lender on any number of occasions. All payments by the Guarantor hereunder shall be made to the Lender in the manner and at the place of payment specified therefor in the Credit Agreement.

2. Guarantor’s Agreement to Pay Enforcement Costs. The Guarantor further agrees, as the principal obligor and not as a guarantor only, to pay to the Lender, on demand, all reasonable costs and expenses (including court costs and legal expenses) incurred or expended by the Lender in connection with the Guaranty Obligations, this Guaranty and the enforcement thereof, together with interest on amounts recoverable under this Section 2 from the time when such amounts become due until payment, whether before or after judgment, at the rate of interest for overdue principal set forth in the Credit Agreement.

3. Waivers by Guarantor; Lender’s Freedom To Act. The Guarantor agrees that the Guaranty Obligations will be paid and performed strictly in accordance with their respective terms regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Lender with respect thereto. Except as specifically provided herein, the Guarantor waives promptness, diligence, presentment, demand, protest, notice of acceptance, notice of any Guaranty Obligations incurred and all other notices of any kind, all defenses that may be available by virtue of any valuation, stay, moratorium law or other similar law now or hereafter in effect, any right to require the marshalling of assets of the Borrower or any other entity or other person primarily or secondarily liable with respect to any of the Guaranty Obligations, and all suretyship defenses generally. Without limiting the generality of the foregoing, the Guarantor agrees, to the fullest extent permitted by law, that the obligations of the Guarantor hereunder shall not be released or discharged, in whole or in part, or otherwise affected by (i) the failure of the Lender to assert any claim or demand or to enforce any right or remedy against the Borrower or any other entity or other person primarily or secondarily liable with respect to any of the Guaranty Obligations; (ii) any extensions, compromises, refinancings, consolidations or renewals of, or alteration of the terms of, any Guaranty Obligation; (iii) any change in the time, place or manner of payment of any of the Guaranty Obligations or any rescissions, waivers, compromises, refinancings, consolidations or other amendments or modifications of any of the terms or provisions of the Credit Agreement or the other Loan Documents (as defined in the Credit Agreement) or any other agreement evidencing, securing or otherwise executed in connection with any of the Guaranty Obligations; (iv) the addition, substitution or release of any entity primarily or secondarily liable for any Guaranty Obligation; (v) the adequacy of any rights the Lender may have against any collateral or other means of obtaining repayment of the Guaranty Obligations; (vi) the impairment of any collateral securing the Guaranty Obligations, including without limitation the failure to perfect or preserve any rights the Lender might have in such collateral or the substitution, exchange, surrender, release, loss or destruction of any such collateral; or (vii) any other act or omission that might in any manner or to any extent vary the risk of the Guarantor or otherwise operate as a release or discharge of the Guarantor, all of which may be done without notice to the Guarantor. To the fullest extent permitted by law, the Guarantor hereby expressly waives any and all rights or defenses arising by reason of (i) any “one action” or “anti-deficiency” law which would otherwise prevent the Lender from bringing any action, including any claim for a deficiency, or exercising any other right or remedy (including any right of set-off), against the Guarantor before or after the Lender’s commencement or completion of any foreclosure action, whether judicially,

- 2 -

by exercise of power of sale or otherwise, or (ii) any other law which in any other way would otherwise require any election of remedies by the Lender.

4. Unenforceability of Obligations Against Borrower. If for any reason the Borrower has no legal existence or is under no legal obligation to discharge any of the Guaranty Obligations, or if any of the Guaranty Obligations have become irrecoverable from the Borrower by reason of the Borrower’s insolvency, bankruptcy or reorganization or by other operation of law or for any other reason, this Guaranty shall nevertheless be binding on the Guarantor to the same extent as if the Guarantor at all times had been the principal obligor on all such Guaranty Obligations. In the event that acceleration of the time for payment of any of the Guaranty Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Borrower, or for any other reason, all such amounts otherwise subject to acceleration under the terms of the Credit Agreement or any other agreement evidencing, securing or otherwise executed in connection with any Guaranty Obligation shall be immediately due and payable by the Guarantor.

5. Subrogation; Subordination. Until the payment and performance in full of all of the Guaranty Obligations, the Guarantor shall not exercise and hereby waives any rights against the Borrower arising as a result of payment by the Guarantor hereunder, by way of subrogation, reimbursement, restitution or otherwise, and will not prove any claim in respect of any payment hereunder in competition with the Lender in bankruptcy or insolvency proceedings of any nature; the Guarantor will not claim any set-off or counterclaim against the Borrower in respect of any liability of the Guarantor to the Borrower; and the Guarantor waives any benefit of and any right to participate in any collateral that may be held by the Lender. The payment of any amounts due with respect to any indebtedness of the Borrower now or hereafter held by the Guarantor is hereby subordinated to the prior payment in full of the Guaranty Obligations; provided, however, that, until the occurrence of any default in the payment or performance of the Guaranty Obligations, the Borrower may pay any such indebtedness of the Borrower to the Guarantor. The Guarantor agrees that after the occurrence of any default in the payment or performance of the Guaranty Obligations, the Guarantor will not demand, sue for or otherwise attempt to collect any such indebtedness of the Borrower to the Guarantor until the Guaranty Obligations shall have been paid in full. If, notwithstanding the foregoing sentence, the Guarantor shall collect, enforce or receive any amounts in respect of such indebtedness while any Guaranty Obligations are still outstanding, such amounts shall be collected, enforced and received by the Guarantor as trustee for the Lender and be paid over to the Lender on account of the Guaranty Obligations without affecting in any manner the liability of the Guarantor under the other provisions of this Guaranty.

6. Guarantor’s Non-Reliance. The Guarantor warrants to and agrees with the Lender that the Guarantor has adequate means to obtain from the Borrower or others on a continuing basis information concerning the Borrower’s financial condition and affairs, and that the Guarantor is not relying on the Lender to provide such information at the date of executing this Guaranty or at any time thereafter.

7. Further Assurances. The Guarantor agrees that it will from time to time, at the request of either Lender, do all such things and execute all such documents as such Lender may reasonably consider necessary or desirable to give full effect to this Guaranty and to perfect and preserve the rights and powers of the Lender hereunder.

9. Termination; Reinstatement. This Guaranty shall remain in full force and effect until the Lender is given written notice of the Guarantor’s intention to discontinue this Guaranty, notwithstanding any intermediate or temporary payment or settlement of the whole or any part of the Guaranty Obligations. No such notice shall be effective unless received and acknowledged by an officer of the Lender at the address for notices set forth in Section 12 below. No such notice shall affect any rights of the Lender hereunder, including without limitation the rights set forth in Sections 3 and 5, with respect to any Guaranty Obligations incurred or accrued prior to the receipt of such notice or any Guaranty Obligations incurred or accrued pursuant to any contract or commitment in existence prior to such receipt. This Guaranty shall continue to be effective or be reinstated if at any time any payment made or value received with respect to any Guaranty Obligation is rescinded or must otherwise be returned by either Lender upon the insolvency, bankruptcy or reorganization of the Borrower, or otherwise, all as though such payment had not been made or value received.

10. Successors and Assigns. This Guaranty shall be binding upon the Guarantor, its successors and assigns, and shall inure to the benefit of and be enforceable by the Lender and their successors, transferees and assigns. Without limiting the generality of the foregoing sentence, to the extent permitted by the Credit Agreement, each Lender may assign or otherwise transfer the Credit Agreement, the other Loan Documents or any other agreement or note held by it evidencing, securing or otherwise executed in connection with the Guaranty Obligations, or sell participations in any interest therein, to any other entity or other person, and such other entity or other person shall thereupon become vested, to the extent set forth in the agreement evidencing such assignment, transfer or participation, with all the rights in respect thereof granted to such Lender herein. The Guarantor may not assign any of its obligations hereunder.

11. Amendments and Waivers. No amendment or waiver of any provision of this Guaranty nor consent to any departure by the Guarantor therefrom shall be effective unless the same shall be in writing and signed by the Lender. No failure on the part of the Lender to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right hereunder preclude any other or further exercise thereof or the exercise of any other right.

12. Notices. All notices and other communications called for hereunder shall be made in writing and, unless otherwise specifically provided herein, shall be deemed to have been duly made or given when delivered by hand or mailed first class mail postage prepaid or, in the case of telecopied notice, when transmitted, receipt confirmed, addressed as follows: if to the Guarantor, at the address or telecopier number set forth below, and if to the Lender, at 161 Worcester Road, Suite 204, Framingham, Massachusetts 01701, Attention: Ann Meade, Vice President, or at such address as any party may designate in writing.

13. Governing Law; Consent to Jurisdiction. This Guaranty is intended to take effect as a sealed instrument and shall be governed by, and construed in accordance with, the laws of The Commonwealth of Massachusetts (excluding the laws applicable to conflicts or choice of law).

hereby waives any objection that it may now or hereafter have to the venue of any such suit or any such court or that such suit was brought in an inconvenient court.

14. Waiver of Jury Trial. EACH OF THE GUARANTOR AND EACH OF THE LENDER HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS GUARANTY, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY OF SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by law, the Guarantor and the Lender each hereby waives any right that it may have to claim or recover in any litigation referred to in the preceding sentence any special, exemplary, punitive or consequential damages or any damages other than or in addition to, actual damages. The Guarantor (a) certifies that neither the Lender nor any representative, agent or attorney of the Lender has represented, expressly or otherwise, that the Lender would not, in the event of litigation, seek to enforce the foregoing waivers and (b) acknowledges that, in entering into the Credit Agreement and the other Loan Documents to which the Lender is a party, the Lender is relying upon, among other things, the waivers and certifications contained in this Section 14.

3. Delivery and Registration of Collateral.

(e) This Agreement, and the delivery to Secured Party of the Pledged Interests representing Collateral (or the control agreements referred to in Section 3 of this Agreement),

- 5 -

Without limiting the generality of the foregoing, Pledgor will: (i) at the request of Secured Party, mark conspicuously each of its records pertaining to the Collateral with a legend, in form and substance reasonably satisfactory to Secured Party, indicating that such Collateral is subject to the security interest granted hereby; (ii) execute and such instruments or notices, as may be necessary or reasonably desirable, or as Secured Party may request, in order to perfect and preserve the first priority security interests granted or purported to be granted hereby; (iii) allow inspection of the Collateral by Secured Party or Persons designated by Secured Party; and (iv) appear in and defend any action or proceeding that may affect Pledgor’s title to or Secured Party’s security interest in the Collateral.

(b) Pledgor hereby authorizes Secured Party to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral.

(c) Pledgor will furnish to Secured Party, upon the request of Secured Party: (i) a certificate executed by an authorized officer of Pledgor, and dated as of the date of delivery to Secured Party, itemizing in such detail as Secured Party may request, the Collateral which, as of the date of such certificate, has been delivered to Secured Party by Pledgor pursuant to the

- 6 -

provisions of this Agreement; and (ii) such statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Secured Party may request.

7. Covenants of Pledgor.

Pledgor shall:

(a) Perform each and every covenant in the Credit Documents applicable to Pledgor; and

(b) Neither change its jurisdiction of organization nor cease to be a Registered Organization, in each case, without giving Secured Party at least thirty (30) days prior written notice thereof.

8. Secured Party as Pledgor’s Attorney-in-Fact.

Pledgor hereby irrevocably appoints Secured Party as Pledgor’s attorney-in-fact, with full authority in the place and stead of Pledgor and in the name of Pledgor, Secured Party or otherwise, from time to time at Secured Party’s discretion, to take any action and to execute any instrument that Secured Party may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, including: (i) upon the occurrence and during the continuance of an Event of Default, to receive, indorse, and collect all instruments made payable to Pledgor representing any dividend, interest payment or other distribution in respect of the Collateral or any part thereof to the extent permitted hereunder and to give full discharge for the same and to execute and file governmental notifications and reporting forms; (ii) to enter into any control agreements Secured Party deems necessary pursuant to Section 3 of this Agreement; or (iii) after the occurrence of an Event of Default and while it is continuing to arrange for the transfer of the Collateral on the books of any of the Issuers or any other Person to the name of Secured Party or to the name of Secured Party’s nominee.

9. Remedies upon Default.

Upon the occurrence and during the continuance of an Event of Default:

(a) Secured Party may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the Code (irrespective of whether the Code applies to the affected items of Collateral), and Secured Party may also without notice (except as specified below) sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as Secured Party may deem commercially reasonable, irrespective of the impact of any such sales on the market price of the Collateral. To the maximum extent permitted by applicable law, Secured Party may be the purchaser of any or all of the Collateral at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply all or any part of the Secured Obligations as a credit on account of the purchase price of any Collateral payable at

- 7 -

such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of Pledgor, and Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay, or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) calendar days notice to Pledgor of the time and place of any public sale or the time after which a private sale is to be made shall constitute reasonable notification. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the maximum extent permitted by law, Pledgor hereby waives any claims against Secured Party arising because the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) Pledgor hereby acknowledges that the sale by Secured Party of any Collateral pursuant to the terms hereof in compliance with the Securities Act of 1933 as now in effect or as hereafter amended, or any similar statute hereafter adopted with similar purpose or effect (the “Securities Act”), as well as applicable “Blue Sky” or other state securities laws, may require strict limitations as to the manner in which Secured Party or any subsequent transferee of the Collateral may dispose thereof. Pledgor acknowledges and agrees that in order to protect Secured Party’s interest it may be necessary to sell the Collateral at a price less than the maximum price attainable if a sale were delayed or were made in another manner, such as a public offering under the Securities Act. Without limiting the generality of the foregoing, Pledgor agrees that, upon the occurrence and during the continuation of an Event of Default, Secured Party may, subject to applicable law, from time to time attempt to sell all or any part of the Collateral by a private placement, restricting the bidders and prospective purchasers to those who will represent and agree that they are purchasing for investment only and not for distribution. In so doing, Secured Party may solicit offers to buy the Collateral or any part thereof for cash, from a limited number of investors reasonably believed by Secured Party to be institutional investors or other accredited investors who might be interested in purchasing the Collateral.

(c) PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW: (i) ANY CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME SECURED PARTY DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS SECTION; (ii) ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT IT NOW HAS OR MAY AT ANY TIME IN THE FUTURE HAVE UNDER ANY RULE OF LAW OR STATUTE NOW EXISTING OR HEREAFTER ENACTED; AND (iii) EXCEPT AS SET FORTH IN SUBSECTION (a) OF THIS SECTION 9, ANY REQUIREMENT OF NOTICE, DEMAND, OR ADVERTISEMENT FOR SALE.

10. Application of Proceeds.

Upon the occurrence and during the continuance of an Event of Default, any cash held by Secured Party as Collateral and all cash Proceeds received by Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral pursuant to the

- 8 -

exercise by Secured Party of its remedies as a secured creditor as provided in Section 9 shall be applied from time to time by Secured Party as provided in the Credit Agreement.

11. Indemnity and Expenses.

Pledgor agrees:

(a) To indemnify and hold harmless Secured Party and each of its directors, officers, employees, agents and affiliates from and against any and all claims, damages, demands, losses, obligations, judgments and liabilities (including, without limitation, reasonable attorneys’ fees and expenses) in any way arising out of or in connection with this Agreement or the Secured Obligations, except to the extent the same shall arise as a result of the gross negligence or willful misconduct of the party seeking to be indemnified; and

(b) To pay and reimburse Secured Party upon demand for all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) that Secured Party may incur in connection with (i) the custody, use or preservation of, or the sale of, collection from or other realization upon, any of the Collateral, including the reasonable expenses of re-taking, holding, preparing for sale or lease, selling or otherwise disposing of or realizing on the Collateral, (ii) the exercise or enforcement of any rights or remedies granted hereunder, under the Credit Agreement, or under any of the other Credit Documents or otherwise available to it (whether at law, in equity or otherwise), or (iii) the failure by Pledgor to perform or observe any of the provisions hereof. The provisions of this Section shall survive the execution and delivery of this Agreement, the repayment of any of the Secured Obligations, the termination of the commitments of Secured Party under the Credit Agreement and the termination of this Agreement or any other Credit Document.

12. Duties of Secured Party.

The powers conferred on Secured Party hereunder are solely to protect its interests in the Collateral and shall not impose on it any duty to exercise such powers. Except as provided in Section 9-207 of the Code, Secured Party shall have no duty with respect to the Collateral or any responsibility for taking any necessary steps to preserve rights against any Persons with respect to any Collateral.

13. Choice of Law and Venue; Submission to Jurisdiction; Service of Process.

(a) THE VALIDITY OF THIS AGREEMENT, ITS CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS (WITHOUT REFERENCE TO THE CHOICE OF LAW PRINCIPLES THEREOF). THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COMMONWEALTH OF MASSACHUSETTS OR, AT THE SOLE OPTION OF SECURED PARTY, IN ANY OTHER COURT IN WHICH SECURED PARTY SHALL INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND

- 9 -

WHICH HAS SUBJECT MATTER JURISDICTION OVER THE MATTER IN CONTROVERSY.

(b) PLEDGOR HEREBY SUBMITS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, TO THE JURISDICTION OF THE AFORESAID COURTS AND WAIVES, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION.

(c) PLEDGOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT, OR OTHER PROCESS ISSUED IN ANY ACTION OR PROCEEDING AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINT, OR OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO PLEDGOR AT ITS ADDRESS FOR NOTICES IN ACCORDANCE WITH THIS AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF PLEDGOR’S ACTUAL RECEIPT THEREOF OR THREE DAYS AFTER DEPOSIT IN THE UNITED STATES MAILS, PROPER POSTAGE PREPAID.

3. Delivery and Registration of Collateral.

(b) Upon the occurrence and during the continuance of an Event of Default, all rights of Pledgor to exercise the voting and other consensual rights or receive and retain cash dividends or distributions that it would otherwise be entitled to exercise or receive and retain, as applicable pursuant to Section 4(a), shall cease, and all such rights shall thereupon become vested in Secured Party, who shall thereupon have the sole right to exercise such voting or other consensual rights and to receive and retain such cash dividends and distributions.

(e) This Agreement, and the delivery to Secured Party of the Pledged Interests representing Collateral (or the control agreements referred to in Section 3 of this Agreement),

- 5 -

Without limiting the generality of the foregoing, Pledgor will: (i) at the request of Secured Party, mark conspicuously each of its records pertaining to the Collateral with a legend, in form and substance reasonably satisfactory to Secured Party, indicating that such Collateral is subject to the security interest granted hereby; (ii) execute and such instruments or notices, as may be necessary or reasonably desirable, or as Secured Party may request, in order to perfect and preserve the first priority security interests granted or purported to be granted hereby; (iii) allow inspection of the Collateral by Secured Party or Persons designated by Secured Party; and (iv) appear in and defend any action or proceeding that may affect Pledgor’s title to or Secured Party’s security interest in the Collateral.

(b) Pledgor hereby authorizes Secured Party to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral.

(c) Pledgor will furnish to Secured Party, upon the request of Secured Party: (i) a certificate executed by an authorized officer of Pledgor, and dated as of the date of delivery to Secured Party, itemizing in such detail as Secured Party may request, the Collateral which, as of the date of such certificate, has been delivered to Secured Party by Pledgor pursuant to the

- 6 -

provisions of this Agreement; and (ii) such statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Secured Party may request.

7. Covenants of Pledgor.

Pledgor shall:

(a) Perform each and every covenant in the Credit Documents applicable to Pledgor; and

(b) Neither change its jurisdiction of organization nor cease to be a Registered Organization, in each case, without giving Secured Party at least thirty (30) days prior written notice thereof.

8. Secured Party as Pledgor’s Attorney-in-Fact.

Pledgor hereby irrevocably appoints Secured Party as Pledgor’s attorney-in-fact, with full authority in the place and stead of Pledgor and in the name of Pledgor, Secured Party or otherwise, from time to time at Secured Party’s discretion, to take any action and to execute any instrument that Secured Party may reasonably deem necessary or advisable to accomplish the purposes of this Agreement, including: (i) upon the occurrence and during the continuance of an Event of Default, to receive, indorse, and collect all instruments made payable to Pledgor representing any dividend, interest payment or other distribution in respect of the Collateral or any part thereof to the extent permitted hereunder and to give full discharge for the same and to execute and file governmental notifications and reporting forms; (ii) to enter into any control agreements Secured Party deems necessary pursuant to Section 3 of this Agreement; or (iii) after the occurrence of an Event of Default and while it is continuing to arrange for the transfer of the Collateral on the books of any of the Issuers or any other Person to the name of Secured Party or to the name of Secured Party’s nominee.

9. Remedies upon Default.

Upon the occurrence and during the continuance of an Event of Default:

(a) Secured Party may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party on default under the Code (irrespective of whether the Code applies to the affected items of Collateral), and Secured Party may also without notice (except as specified below) sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of Secured Party’s offices or elsewhere, for cash, on credit or for future delivery, at such time or times and at such price or prices and upon such other terms as Secured Party may deem commercially reasonable, irrespective of the impact of any such sales on the market price of the Collateral. To the maximum extent permitted by applicable law, Secured Party may be the purchaser of any or all of the Collateral at any such sale and shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply all or any part of the Secured Obligations as a credit on account of the purchase price of any Collateral payable at

- 7 -

such sale. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of Pledgor, and Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay, or appraisal that it now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. Pledgor agrees that, to the extent notice of sale shall be required by law, at least ten (10) calendar days notice to Pledgor of the time and place of any public sale or the time after which a private sale is to be made shall constitute reasonable notification. Secured Party shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. Secured Party may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned. To the maximum extent permitted by law, Pledgor hereby waives any claims against Secured Party arising because the price at which any Collateral may have been sold at such a private sale was less than the price that might have been obtained at a public sale, even if Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree.

(b) Pledgor hereby acknowledges that the sale by Secured Party of any Collateral pursuant to the terms hereof in compliance with the Securities Act of 1933 as now in effect or as hereafter amended, or any similar statute hereafter adopted with similar purpose or effect (the “Securities Act”), as well as applicable “Blue Sky” or other state securities laws, may require strict limitations as to the manner in which Secured Party or any subsequent transferee of the Collateral may dispose thereof. Pledgor acknowledges and agrees that in order to protect Secured Party’s interest it may be necessary to sell the Collateral at a price less than the maximum price attainable if a sale were delayed or were made in another manner, such as a public offering under the Securities Act. Without limiting the generality of the foregoing, Pledgor agrees that, upon the occurrence and during the continuation of an Event of Default, Secured Party may, subject to applicable law, from time to time attempt to sell all or any part of the Collateral by a private placement, restricting the bidders and prospective purchasers to those who will represent and agree that they are purchasing for investment only and not for distribution. In so doing, Secured Party may solicit offers to buy the Collateral or any part thereof for cash, from a limited number of investors reasonably believed by Secured Party to be institutional investors or other accredited investors who might be interested in purchasing the Collateral.

(c) PLEDGOR EXPRESSLY WAIVES TO THE MAXIMUM EXTENT PERMITTED BY LAW: (i) ANY CONSTITUTIONAL OR OTHER RIGHT TO A JUDICIAL HEARING PRIOR TO THE TIME SECURED PARTY DISPOSES OF ALL OR ANY PART OF THE COLLATERAL AS PROVIDED IN THIS SECTION; (ii) ALL RIGHTS OF REDEMPTION, STAY, OR APPRAISAL THAT IT NOW HAS OR MAY AT ANY TIME IN THE FUTURE HAVE UNDER ANY RULE OF LAW OR STATUTE NOW EXISTING OR HEREAFTER ENACTED; AND (iii) EXCEPT AS SET FORTH IN SUBSECTION (a) OF THIS SECTION 9, ANY REQUIREMENT OF NOTICE, DEMAND, OR ADVERTISEMENT FOR SALE.

10. Application of Proceeds.

Upon the occurrence and during the continuance of an Event of Default, any cash held by Secured Party as Collateral and all cash Proceeds received by Secured Party in respect of any sale of, collection from, or other realization upon all or any part of the Collateral pursuant to the

- 8 -

exercise by Secured Party of its remedies as a secured creditor as provided in Section 9 shall be applied from time to time by Secured Party as provided in the Credit Agreement.

11. Indemnity and Expenses.

Pledgor agrees:

(a) To indemnify and hold harmless Secured Party and each of its directors, officers, employees, agents and affiliates from and against any and all claims, damages, demands, losses, obligations, judgments and liabilities (including, without limitation, reasonable attorneys’ fees and expenses) in any way arising out of or in connection with this Agreement or the Secured Obligations, except to the extent the same shall arise as a result of the gross negligence or willful misconduct of the party seeking to be indemnified; and

(b) To pay and reimburse Secured Party upon demand for all reasonable costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses) that Secured Party may incur in connection with (i) the custody, use or preservation of, or the sale of, collection from or other realization upon, any of the Collateral, including the reasonable expenses of re-taking, holding, preparing for sale or lease, selling or otherwise disposing of or realizing on the Collateral, (ii) the exercise or enforcement of any rights or remedies granted hereunder, under the Credit Agreement, or under any of the other Credit Documents or otherwise available to it (whether at law, in equity or otherwise), or (iii) the failure by Pledgor to perform or observe any of the provisions hereof. The provisions of this Section shall survive the execution and delivery of this Agreement, the repayment of any of the Secured Obligations, the termination of the commitments of Secured Party under the Credit Agreement and the termination of this Agreement or any other Credit Document.

12. Duties of Secured Party.

The powers conferred on Secured Party hereunder are solely to protect its interests in the Collateral and shall not impose on it any duty to exercise such powers. Except as provided in Section 9-207 of the Code, Secured Party shall have no duty with respect to the Collateral or any responsibility for taking any necessary steps to preserve rights against any Persons with respect to any Collateral.

13. Choice of Law and Venue; Submission to Jurisdiction; Service of Process.

(a) THE VALIDITY OF THIS AGREEMENT, ITS CONSTRUCTION, INTERPRETATION, AND ENFORCEMENT, AND THE RIGHTS OF THE PARTIES HERETO SHALL BE DETERMINED UNDER, GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS (WITHOUT REFERENCE TO THE CHOICE OF LAW PRINCIPLES THEREOF). THE PARTIES AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS LOCATED IN THE COMMONWEALTH OF MASSACHUSETTS OR, AT THE SOLE OPTION OF SECURED PARTY, IN ANY OTHER COURT IN WHICH SECURED PARTY SHALL INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND

- 9 -

WHICH HAS SUBJECT MATTER JURISDICTION OVER THE MATTER IN CONTROVERSY.

(b) PLEDGOR HEREBY SUBMITS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, TO THE JURISDICTION OF THE AFORESAID COURTS AND WAIVES, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION.

(c) PLEDGOR HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT, OR OTHER PROCESS ISSUED IN ANY ACTION OR PROCEEDING AND AGREES THAT SERVICE OF SUCH SUMMONS, COMPLAINT, OR OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL ADDRESSED TO PLEDGOR AT ITS ADDRESS FOR NOTICES IN ACCORDANCE WITH THIS AGREEMENT AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF PLEDGOR’S ACTUAL RECEIPT THEREOF OR THREE DAYS AFTER DEPOSIT IN THE UNITED STATES MAILS, PROPER POSTAGE PREPAID.

(d) NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO AFFECT THE RIGHT OF SECURED PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW, OR TO PRECLUDE THE ENFORCEMENT BY SECURED PARTY OF ANY JUDGMENT OR ORDER OBTAINED IN SUCH FORUM OR THE TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME IN ANY OTHER APPROPRIATE FORUM OR JURISDICTION.
