Brown, President and Chief Executive Officer National Dentex Corporation 526 Boston Post Road Wayland, MA 01778 Re: LOAN AGREEMENT Dear Mr. Brown: This Amended and Restated Loan Agreement (the "AGREEMENT") is made as of August 9, 2005, by and among (a)(i) National Dentex Corporation, a Massachusetts corporation ("DENTEX") and (ii) Green Dental Laboratories, Inc., an Arkansas corporation ("GREEN" and, collectively with Dentex, the "BORROWERS"), and (b) Bank of America, N.A., organized and existing under the laws of the United States (the "Bank"). WHEREAS, Dentex and the Bank are party to that certain Loan Agreement dated as of June 30, 2004 (the "EXISTING LOAN Agreement") consisting of a $5,000,000 revolving credit facility and a $20,000,000 acquisition revolving credit facility; WHEREAS, Dentex requested the Bank's consent to draw $20,000,000 under the acquisition revolving credit facility to finance in part Dentex's purchase of all of the issued and outstanding capital stock of Green; WHEREAS, the Bank consented to Dentex's use of the acquisition revolving credit facility to finance in part the purchase of all of the issued and outstanding capital stock of Green; and WHEREAS, the Bank, Dentex and Greeen have agreed to amend and restate the Existing Loan Agreement to, among other things: (a) add a new term loan facility in the aggregate principal amount of $20,000,000; (b) use the proceeds of such term loan to repay the acquisition revolving credit facility; and (c) include Green as a borrower thereunder. NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged (these recitals being an integral part of this Loan Agreement) the parties hereto hereby agree that the Existing Loan Agreement is amended and restated in its entirety as follows: -1- 1. THE CREDIT FACILITY; ADVANCES. (a) THE CREDIT FACILITY. The Credit Facility shall consist of the following:(i) a revolving line of credit (the "FIRST LINE OF CREDIT") in an amount equal to $5,000,000, available until the day prior to, and due and payable on, the Lines of Credit Termination Date (as hereinafter defined); the First Line of Credit shall include a sublimit for the issuance, on the terms and conditions set forth in this Agreement, of letters of credit for the Borrowers' account, PROVIDED that the Bank's LC Exposure (as hereinafter defined) at any time shall not exceed $1,500,000. Advances under the First Line of Credit may be used by the Borrowers for their general corporate purposes, to refinance existing indebtedness and for the issuance of Letters of Credit. (ii) a revolving line of credit (the "SECOND LINE OF CREDIT") in an amount equal to $20,000,000, available until the day prior to, and due and payable on, the Lines of Credit Termination Date (The First Line of Credit and the Second Line of Credit may collectively hereinafter be referred to as the "LINES OF CREDIT"). Advances under the Second Line of Credit may be used by the Borrowers solely to fund acquisitions by the Borrowers in accordance with Section 8 and the other terms and conditions hereof. (iii) a term loan in the principal amount of $20,000,000 (the "TERM LOAN") to be funded by the Bank on the Closing Date. The Borrowers, jointly and severally, promise to pay to the Bank the principal amount of the Term Loan in consecutive installments on the last day of each calendar month, in an amount calculated on the basis of a seven (7) year amortization schedule, commencing on August 9, 2005, with a final payment on the Term Loan Termination Date in an amount equal to the unpaid balance of the Term Loan. The proceeds of the Term Loan shall be applied on the Closing Date solely to the repayment of the Second Line of Credit. No amount repaid with respect to the Term Loan may be reborrowed. (b) ADVANCES After the Closing, advances under the Lines of Credit may be made, from time to time, until the day prior to the Lines of Credit Termination Date, in such amounts as the Borrowers may request; PROVIDED that in the case of the First Line of Credit the aggregate principal amount of all advances at any time outstanding under the First Line of Credit (after giving effect to all amounts requested) PLUS the aggregate LC Exposure at such time, shall not exceed $5,000,000; and in the case of the Second Line of Credit, the aggregate principal amount of all advances at any time outstanding under the Second Line of Credit (after giving effect to all amounts requested) shall not exceed $20,000,000, provided that any such advances under the Second Line of Credit are subject to the provisions set forth in Section 8(c) and 6(k) hereof; and PROVIDED, FURTHER, that at the time the Borrowers request an advance under the Lines of Credit and after giving effect to the making thereof, no Default or Event of Default has occurred and is continuing. Subject to the terms of this Agreement, advances under the First Line of Credit, once repaid, may be reborrowed; advances under the Second Line of Credit, once repaid, may be reborrowed, subject to the provisions set forth in Section 8(c) and 6(k) hereof. If at any time the outstanding principal amount of the advances under a Line of Credit exceeds the amount determined by reference to the limits set forth in the first sentence of this Section 1(b), the Borrowers shall promptly pay an amount equal to such excess to the Bank. -2- 2. INTEREST; PAYMENTS; FEES; BORROWING. (a) INTEREST. Each advance, from time to time, under either Line of Credit, and the Term Loan or any portion thereof as applicable shall bear interest (i) at an annual rate equal to the Prime Rate (as hereinafter defined) plus the Applicable Margin with respect thereto as in effect from time to time (in which case such advance or Term Loan or portion thereof, as applicable, shall be designated as a "PRIME RATE LOAN"), (ii) at the option of the Borrowers, at the LIBOR Lending Rate for the applicable Interest Period plus the Applicable Margin with respect thereto as in effect from time to time (in which case such advance or Term Loan or portion thereof, as applicable, shall be designated as a "LIBOR RATE LOAN"), (iii) at the option of the Borrowers, at the Cost of Funds Rate for the applicable Interest Period plus the Applicable Margin with respect thereto as in effect from time to time (in which case such advance or Term Loan or portion thereof, as applicable, shall be designated as a "COST OF FUNDS RATE LOAN"); or (iv) at the option of the Borrowers, at a fixed rate equal to the rate announced by the Bank on the date of the Notice of Borrowing or on the date of any conversion of a Loan to such fixed rate (in which case such advance or Term Loan or portion thereof, as applicable, shall be designated as a "FIXED RATE LOAN"). If any such interest rate is unlawful, then the rate shall be the highest rate permitted under applicable law. Interest shall be payable (i) in the case of Prime Rate Loans and Fixed Rate Loans, in arrears on the first (1st) Business Day of each month, (ii) in the case of LIBOR Rate Loans and Cost of Funds Rate Loans, on the Interest Payment Dates applicable thereto, and (iii) in the case of any advance, when such advance shall be due (whether at maturity, by reason of prepayment or acceleration or otherwise) or converted, but only to the extent then accrued on the amount so due or converted. Each change in the rate of interest payable on the Prime Rate Loans shall take effect simultaneously with the corresponding change in the Prime Rate. After the occurrence and during the continuance of a Default or Event of Default and until such Default or Event of Default has been cured, remedied or waived by the Bank, the principal amount of the Lines of Credit and the Term Loan shall bear interest at the annual rate of two percent (2%) above the Prime Rate, or, if such rate is unlawful, the highest rate permitted under applicable law (the "POST-DEFAULT RATE"). Any amounts overdue under this Agreement shall bear interest at the Post-Default Rate. Interest at the Post-Default Rate shall be payable on demand. (b) PAYMENTS. All payments received by the Bank from any of the Borrowers, except for the payments referred to in Subsection (c) below and regularly scheduled payments of the Term Loan under Section 1(a)(iii) hereof, shall be applied first to expenses due hereunder, then to accrued interest and then to principal. Upon the occurrence and during the continuance of an Event of Default hereunder, however, payments may be applied in such manner as the Bank may, in its sole discretion, determine. All computations of interest shall be made on the basis of a 360-day year. Advances under the Lines of Credit shall be evidenced by this Agreement, the records of the Bank and, (i)(A) with respect to the First Line of Credit, a promissory note in the form of Exhibit A hereto (the "AMENDED AND RESTATED FIRST LINE OF CREDIT NOTE"), and (B) with respect to the Second Line of Credit, a promissory note in the form of Exhibit B hereto (the "AMENDED AND RESTATED SECOND LINE OF CREDIT NOTE"), each due on the Lines of Credit Termination Date (references in this Agreement to the term "Amended and Restated Line of Credit Note" shall, except where the context does not otherwise permit, be deemed to apply to both the Amended and Restated First Line of Credit Note and the Amended and Restated Second Line of Credit Note); and (ii) with respect to the Term Loan, a promissory note in the form of Exhibit C hereto (the "TERM NOTE"), dated as of the Closing Date and due on the fifth (5th) anniversary of the Closing Date. The LC Reimbursement Obligations shall be evidenced by this Agreement, the records of the Bank and the Letters of Credit. The records of the Bank shall be prima facie evidence of the advances hereunder, the aggregate unpaid amount of the Term Loan and the LC Reimbursement Obligations and, in each case, of accrued interest thereon and of all payments made in respect thereof. -3- All payments due to the Bank hereunder, under the Amended and Restated Line of Credit Notes or the Term Note shall be made in U.S. Dollars in immediately available funds at Bank of America, N.A., 100 Federal Street, Boston, MA 02110 or at such other address as the Bank may designate by notice to the Borrowers. A payment to the Bank shall not be deemed to have been made on any day unless such payment shall have been received by the Bank, at such address, in U.S. Dollars in immediately available funds, no later than 12:00 noon (Boston time) on such day. If any payment under this Agreement becomes due and payable on a day that is not a Business Day and this Agreement does not otherwise provide for such contingency, the maturity thereof shall be extended to the next succeeding Business Day, and with respect to any payment of principal, interest thereon shall be payable at the then applicable rate during any such extension. (c) ADDITIONAL PAYMENTS. In addition to the amounts specified above, the Borrowers shall pay to the Bank the following in connection with the Credit Facility:(i) an unused facility fee equal to 1/8 of 1% per annum of the average unborrowed portion of the First Line of Credit (giving effect, without duplication, to the Bank's LC Exposure thereunder), such average to be computed for the three-month period preceding each Payment Date on which such unused facility fee is payable (or such longer or shorter period as has elapsed from the Closing Date to the first of such Payment Dates), payable quarterly in arrears on the last Payment Dates specified herein, commencing on the first such date following the Closing Date and on each Payment Date thereafter through the Lines of Credit Termination Date (with the last such fee payable on the Lines of Credit Termination Date); -4- (ii) a facility fee of $10,000.00 per annum for the Second Line of Credit, payable annually in advance on the last day of June in each year, commencing on June 30, 2004; (iii) a Letter of Credit issuance fee equal to 1% of the original face amount of each Letter of Credit issued hereunder, payable at the time of issuance of such Letter of Credit; and (iv) an audit fee of $1,000 for each field audit of the Borrower's books and records performed by the Bank, up to a maximum of $1,000 in audit fees for each 12-month period. (d) VOLUNTARY PREPAYMENTS OF COST OF FUNDS RATE LOANS, FIXED RATE LOANS AND PRIME RATE LOANS. The Borrowers may, upon notice to the Bank, at any time or from time to time voluntarily prepay any Loan in whole or in part without premium or penalty; PROVIDED that (i) such notice must be received by the Bank not later than 1:00 p.m. (A) three (3) Business Days prior to any date of prepayment of a Cost of Funds Rate Loan or a Fixed Rate Loan and (B) on the date of prepayment of a Prime Rate Loan; (ii) any prepayment of a Cost of Funds Rate Loan shall be in an integral multiple of (x) $500,000 in the case of Cost of Funds Rate Loans advanced under the First Line of Credit, (y) $1,000,000 in the case of Cost of Funds Rate Loans advanced under the Second Line of Credit, and (z) $1,000,000 in the case of Cost of Funds Rate Loans of any portion of the Term Loan; and (iii) any prepayment of a Prime Rate Loan or a Fixed Rate Loan shall be in a principal amount of $500,000 or a whole multiple of $100,000 in excess thereof, or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment and the type(s) of Loan(s) to be prepaid. If such notice is given by the Borrowers, the Borrowers shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Loan shall be accompanied by all accrued interest thereon. Any prepayment of a Fixed Rate Loan shall be accompanied by such accrued interest, together with any Redeployment Costs required pursuant to Section 2(g). (e) NOTICE OF BORROWING. Whenever the Borrowers elect to obtain a LIBOR Rate Loan or Cost of Funds Rate Loan or Fixed Rate Loan under either of the Lines of Credit or in respect of the Term Loan or any portion thereof, they may request that the Bank provide quotes as of any specified date as to the LIBOR Lending Rate or Cost of Funds Rate Loan or Fixed Rate Loan for any or all Interest Periods, and the Bank shall promptly provide such quotes. The Borrowers shall give the Bank prior telecopied or telephone notice, on a Business Day, (i) not later than 10:00 a.m. (Boston time) on the day of any advance with respect to a Prime Rate Loan or Fixed Rate Loan and (ii) not later than 10:00 a.m. (Boston time) at least two (2) Business Days prior to the day of any advance with respect to a LIBOR Rate Loan or Cost of Funds Rate Loan. Each such notice shall be irrevocable once given and shall specify the principal amount of the advance to be made, the date of the advance (which shall be a Business Day), whether each advance is to be maintained as a Prime Rate Loan, Cost of Funds Rate Loan, LIBOR Rate Loan, or Fixed Rate Loan, and in the case of a LIBOR Rate Loan, Cost of Funds Rate Loan or Fixed Rate Loan, the Interest Period applicable thereto. If such notice is given by telephone, it shall be immediately confirmed in writing. In the event that the Borrowers at any time fail in such notice to specify any of the information required by this subsection to be given with respect to a LIBOR Rate Loan, Cost of Funds Rate Loan, or Fixed Rate Loan, then the Borrowers shall be deemed to have requested that the Bank make a Prime Rate Loan. All advances hereunder shall be disbursed by the Bank not later than 12:00 noon (Boston time) on the requested date therefor, in U.S. Dollars in immediately available funds, by credit to the Borrowers' operating account with the Bank. -5- (f) SPECIAL PROVISIONS GOVERNING LOANS Notwithstanding any other provisions of this Agreement to the contrary, the following provisions shall govern with respect to any LIBOR Rate Loans or Cost of Funds Rate Loans (as applicable): (i) REPAYMENT, CONTINUATION AND CONVERSION. Each LIBOR Rate Loan or Cost of Funds Rate Loan shall mature and, with respect to such Loans under the Lines of Credit, become payable in full on the last day of the Interest Period relating thereto. Upon maturity, a LIBOR Rate Loan or Cost of Funds Rate Loan may be continued for an additional Interest Period or may be converted to a Prime Rate Loan as provided in clause (ii) below. (ii) CONTINUATION AND CONVERSION ELECTIONS. Subject to the provisions hereof, the Borrowers shall have the option (A) to convert at any time one or more integral multiples of $500,000 of its outstanding Prime Rate Loans under the First Line of Credit into one or more LIBOR Rate Loans, Cost of Funds Rate Loans or Fixed Rate Loans, (B) to convert at any time one or more integral multiples of $1,000,0000 of its outstanding Prime Rate Loans under the Second Line of Credit into one or more LIBOR Rate Loans, Cost of Funds Rate Loans or Fixed Rate Loans, (C) to convert at any time one or more integral multiples of $1,000,000 of its outstanding Prime Rate Loans under the Term Loan into one or more LIBOR Rate Loans, Cost of Funds Rate Loans, or Fixed Rate Loans, (D) effective on and as of the expiration date of the Interest Period of a LIBOR Rate Loan or Cost of Funds Rate Loan, to continue such loan LIBOR Rate Loan or Cost of Funds Rate Loan, respectively, as such, with an equivalent or different Interest Period, or (E) effective on and as of the expiration date of the Interest Period of a LIBOR Rate Loan or Cost of Funds Rate Loan, to convert such loan to a Prime Rate Loan; PROVIDED, HOWEVER, that (x) a LIBOR Rate Loan or Cost of Funds Rate Loans may only be continued pursuant to clause (D) above if the outstanding principal amount of such loan equals or exceeds $500,000 in the case a LIBOR Rate Loan or Cost of Funds Rate Loan advanced under the First Line of Credit, $1,000,000 in the case of a LIBOR Rate Loan or Cost of Funds Rate Loans advanced under the Second Line of Credit, or $1,000,000 in the case of LIBOR Rate Loan or Cost of Funds Rate Loans under the Term Loan; (y) no portion of the outstanding principal amount of any advance may be converted to, or continued as, a LIBOR Rate Loan or Cost of Funds Rate Loan when any Default or Event of Default has occurred and is continuing; and (z) no portion of the outstanding principal amount of any LIBOR Rate Loan or Cost of Funds Rate Loan may be converted to a LIBOR Rate Loan or Cost of Funds Rate Loan, respectively, of a different duration if such LIBOR Rate Loan or Cost of Funds Rate Loan relates to any Hedging Obligations unless the maturity of the relevant Hedging Obligations has been appropriately adjusted in a manner satisfactory to the Bank. -6- The Borrowers shall deliver a notice of conversion/continuation to the Bank, on a Business Day, no later than 10:00 a.m. (Boston time) at least two (2) Business Days in advance of the proposed conversion/continuation date for a LIBOR Rate Loan or a Cost of Funds Rate Loan. A notice of conversion/continuation shall, in the case of a conversion to, or continuation of, a LIBOR Rate Loan or a Cost of Funds Rate Loan, be irrevocable and shall be given by the Borrowers to specify (i) the proposed conversion/continuation date (which shall be a Business Day), (ii) whether the Loan to be converted/continued is a First Line of Credit Loan, Second Line of Credit Loan or the Term Loan or a portion thereof, (iii) the amount of the First or Second Line of Credit Loan or the Term Loan, or a portion thereof, to be converted/continued, (iv) (A) whether the First or Second Line of Credit Loan or portion of the Term Loan to be converted/continued is a Prime Rate Loan, Cost of Funds Rate Loan, LIBOR Rate Loan, or Fixed Rate Loan, and (B) whether the First or Second Line of Credit Loan or portion of the Term Loan into which such First or Second Line of Credit Loan is converted/continued is to be a Prime Rate Loan, Cost of Funds Rate Loan LIBOR Rate Loan, or Fixed Rate Loan, and (v) in the case of a conversion to, or a continuation of, a LIBOR Rate Loan or Cost of Funds Rate Loan, the requested Interest Period. In lieu of delivering the above-described notice, the Borrowers may give the Bank telephonic notice by the required time of any proposed conversion/continuation; PROVIDED that such notice shall be immediately confirmed in writing. If the Borrowers fail to give such notice with respect to a LIBOR Rate Loan or Cost of Funds Rate Loan at least two (2) Business Days before the last day of the then current Interest Period with respect thereto, the Borrowers shall be deemed to have delivered to the Bank a notice to convert such Loan into a Prime Rate Loan and such loan shall, on such last day, automatically convert into a Prime Rate Loan. Any notice of conversion/continuation given pursuant to this subsection shall be irrevocable on and after the date of delivery thereof to the Bank, and the Borrowers shall be bound to convert or continue in accordance therewith. (iii) DETERMINATION AND NOTICE OF LIBOR LENDING RATE, COST OF FUNDS RATE OR FIXED RATE. Promptly after receipt of notice from the Borrowers that they wish to elect a LIBOR Rate Loan, Cost of Funds Rate Loan, or Fixed Rate Loan, the Bank shall determine (which determination shall, absent manifest error, be final, conclusive and binding upon all parties) the applicable LIBOR Lending Rate, Cost of Funds Rate, or Fixed Rate, as applicable, which rate shall apply to the LIBOR Rate Loans, Cost of Funds Rate Loans, or Fixed Rate Loans, as applicable, for which an interest rate is then being determined for the applicable Interest Period, and shall promptly give notice thereof (in writing or by telephone and confirmed in writing) to the Borrowers. -7- (iv) Basis for Determining Interest Rate Inadequate. If the Bank shall have determined that: (A) U.S. Dollar deposits in the relevant amount and for the relevant Interest Period are not available to the Bank in the London interbank market, (B) by reason of circumstances affecting the Bank in the London interbank market, adequate means do not exist for ascertaining the LIBOR Lending Rate applicable hereunder to LIBOR Rate Loans of any duration, or (C) the LIBOR Lending Rate no longer adequately reflects the Bank's cost of funding LIBOR Rate Loans of any duration, then, upon notice from the Bank to the Borrowers and until the Bank shall notify the Borrowers that the circumstances causing such suspension no longer exist, (1) the obligations of the Bank under this Agreement to make or continue any Loans as, or to convert any Loans into, LIBOR Rate Loans of such duration shall forthwith be suspended and (2) each affected outstanding LIBOR Rate Loan shall be converted into a Prime Rate Loan on the last day of the then current Interest Period applicable thereto. (v) LIBOR RATE LENDING UNLAWFUL. If the Bank shall determine (which determination shall, upon notice thereof to the Borrowers, be conclusive and binding on the Borrowers, absent manifest error) 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 Bank to make, continue or maintain any LIBOR Rate Loan as, or to convert any loan into, a LIBOR Rate Loan of a certain duration, the obligations of the Bank to make, continue, maintain or convert into any such LIBOR Rate Loans shall, upon such determination, forthwith be suspended until the Bank shall notify the Borrowers that the circumstances causing such suspension no longer exist, and all LIBOR Rate Loans of such type shall automatically convert into Prime Rate Loans on the last day of the then current Interest Periods applicable thereto or sooner, if required by such law or assertion. (vi) VOLUNTARY PREPAYMENT OF LIBOR RATE LOANS. LIBOR Rate Loans in connection with which the Borrowers have entered into Hedging Obligations with the Bank may not be prepaid; other LIBOR Rate Loans may be prepaid only upon the terms and conditions set forth herein. The Borrowers shall give the Bank, no later than 10:00 a.m. (Boston time), at least four (4) 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 (x) $500,000 in the case of LIBOR Rate Loans advanced under the First Line of Credit, (y) $1,000,000 in the case of LIBOR Rate Loans advanced under the Second Line of Credit, and (z) $1,000,000 in the case of LIBOR Rate Loans of any portion of the Term Loan, 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. -8- Borrowers acknowledge that prepayment or acceleration of a LIBOR Rate Loan during an Interest Period shall result in the Bank 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 Borrowers hereby jointly and severally promise 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 (the "LIBOR PREPAYMENT FEE") determined by the Bank pursuant to the following formula: (1) the then current rate for U.S. 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 (2) the LIBOR Lending Rate applicable to the LIBOR Rate Loan being prepaid, PLUS 1.5%. If the result of this calculation is zero or a negative number, then there shall be no LIBOR Prepayment Fee. If the result of this calculation is a positive number, then the resulting percentage shall be multiplied by: (3) the amount of the LIBOR Rate Loan being prepaid. The resulting amount shall be divided by: (4) 360 and multiplied by: (5) 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 U.S. 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 Prepayment Fee. -9- (vii) INDEMNITIES. In addition to the LIBOR Prepayment Fee, the Borrowers agree to reimburse the Bank (without duplication) for any increase in the cost to the Bank, or reduction in the amount of any sum receivable by the Bank, in respect, or as a result of: (A) any conversion or 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 2(e)(vi) or otherwise; (B) any Loan not being made as a LIBOR Rate Loan in accordance with the borrowing request therefor; (C) any LIBOR Rate Loan not being continued as, or converted into, a LIBOR Rate Loan in accordance with the continuation/conversion notice therefor; or (D) any costs associated with marking to market any Hedging Obligations that (in the reasonable determination of the Bank) 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 2(e)(vi) or otherwise. The Bank shall promptly notify the Borrowers 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 Bank for such increased cost or reduced amount. Such additional amounts shall be payable by the Borrowers to the Bank within five (5) days of its receipt of such notice, and such notice shall, in the absence of manifest error, be conclusive and binding on the Borrowers. The Borrowers understand, agree and acknowledge the following: (i) the Bank does not have any obligation to purchase, sell and/or match funds in connection with the use of the 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 Borrowers have accepted the LIBOR Rate as a reasonable and fair basis for calculating such rate, the LIBOR Prepayment Fee, and other funding losses incurred by the Bank. Borrowers further agree to pay the LIBOR Prepayment Fee and other funding losses, if any, whether or not the Bank elects to purchase, sell and/or match funds. (viii) 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 Bank with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: -10- (A) shall subject the Bank to any tax, duty or other charge with respect to its LIBOR Rate Loans or Letters of Credit issued by it or its obligation to make LIBOR Rate Loans or issue Letters of Credit, or shall change the basis of taxation of payments to the Bank 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 the Letters of Credit or its obligation to make LIBOR Rate Loans or issue Letters of Credit (except for the introduction of, or change in the rate of, tax on the overall net income of the Bank or franchise taxes, imposed by the jurisdiction (or any political subdivision or taxing authority thereof) under the laws of which the Bank is organized or in which the Bank's principal executive office is 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 Bank or shall impose on the Bank or on the London interbank market any other condition affecting its LIBOR Rate Loans or Letters or Credit issued by it or its obligation to make LIBOR Rate Loans or issue Letters of Credit; and the result of any of the foregoing is to increase the cost to the Bank of making or maintaining any LIBOR Rate Loan or issuing any Letter of Credit, or to reduce the amount of any sum received or receivable by the Bank under this Agreement with respect thereto, by an amount deemed by the Bank to be material, then, within 15 days after demand by the Bank, the Borrowers shall pay to the Bank such additional amount or amounts as will compensate the Bank for such increased cost or reduction. A statement of the Bank 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 Borrowers. In determining such amount, the Bank may use any method of averaging and attribution that it (in its sole and absolute discretion) shall deem applicable. (g) VOLUNTARY PREPAYMENT OF FIXED RATE LOANS. Borrowers acknowledge that prepayment of a Fixed Rate Loan prior to the end of the applicable Interest Period shall result in the Bank 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 Fixed Rate Loans shall be accompanied by, and the Borrowers hereby jointly and severally promise to pay, on each date a Fixed Rate Loan is prepaid, in addition to all other sums then owing, the Bank's (i) cost of obtaining funds for the Fixed Rate Loan that is the subject of such prepayment for the period from the date of such prepayment to the last day of the Interest Period in effect (or that would have been in effect) for such Fixed Rate Loan over (ii) the amount of interest likely to be realized by the Bank in redeploying the funds released or not utilized by reason of such prepayment for such period. A certificate of the Bank setting forth any amount or amounts which the Bank is entitled to receive pursuant to this Section shall be delivered to the Borrowers and shall be conclusive absent manifest error. -11- (h) 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 Bank, or person controlling the Bank, and the Bank 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 or the Loans made or Letters of Credit issued by the Bank is reduced to a level below that which the Bank or such controlling person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by the Bank to the Borrowers, the Borrowers shall immediately pay directly to the Bank additional amounts sufficient to compensate the Bank or such controlling person for such reduction in rate of return. A statement of the Bank 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 Borrowers. In determining such amount, the Bank may use any method of averaging and attribution that it (in its reasonable discretion) shall deem applicable.(i) TAXES. All payments by the Borrowers of principal of, and interest on, the 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 Bank'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 Borrowers hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Borrowers will:(i) pay directly to the relevant authority the full amount required to be so withheld or deducted; (ii) promptly forward to the Bank an official receipt or other documentation satisfactory to the Bank evidencing such payment to such authority; and (iii) pay to the Bank such additional amount or amounts as are necessary to ensure that the net amount actually received by the Bank will equal the full amount the Bank would have received had no such withholding or deduction been required. Moreover, if any Taxes are directly asserted against the Bank with respect to any payment received by the Bank hereunder, the Bank may pay such Taxes and the Borrowers will promptly pay such additional amount (including any penalties, interest or expenses) as is necessary in order that the net amount received by the Bank after the payment of such Taxes (including any Taxes on such additional amount) shall equal the amount the Bank would have received had such Taxes not been asserted. If the Borrowers fail to pay any Taxes when due to the appropriate taxing authority or fail to remit to the Bank the required receipts or other required documentary evidence, the Borrowers shall indemnify the Bank for any incremental Taxes, interest or penalties that may become payable by the Bank as a result of any such failure. -12- 3. LETTERS OF CREDIT. (a) ISSUANCE. The Bank agrees, on the terms and conditions set forth in this Agreement, to issue standby letters of credit hereunder (each a "LETTER OF CREDIT") at the request of the Borrowers from time to time prior to the date that is 30 days before the Lines of Credit Termination Date; provided that, immediately after each such Letter of Credit is issued, (i) the LC Exposure shall not exceed $1,500,000, and (ii) the sum of the outstanding principal amount of all First Line of Credit Loans plus the LC Exposure shall not exceed $5,000,000.

(e) DRAWINGS. If the Bank receives a demand for payment under any Letter of Credit issued by it and determines that such demand should be honored, the Bank shall (i) make such payment in accordance with the terms of such Letter of Credit and (ii) reasonably promptly notify the Borrowers as to the amount paid by the Bank as a result of such demand and the date of such payment (an "LC PAYMENT DATE"). (f) REIMBURSEMENT BY THE BORROWERS. If any amount is drawn under any Letter of Credit, the Borrowers irrevocably and unconditionally agree to reimburse the Bank for such amount together with any and all reasonable charges and expenses which the Bank may pay or incur relative to such drawing. Such reimbursement shall be due and payable on the relevant LC Payment Date or the date on which the Bank notifies the Borrowers of such drawing, whichever is later; provided that, if such notice is given after 12:00 noon (Boston time) on the later of such dates, such reimbursement shall be due and payable on the next following Business Day (the date on which it is due and payable being an "LC REIMBURSEMENT DUE DATE"). -13- In addition, the Borrowers agree to pay, on the applicable LC Reimbursement Due Date, interest on each amount drawn under a Letter of Credit, for each day from and including the date such amount is drawn to but excluding such LC Reimbursement Due Date, at a rate per annum equal to the Applicable Margin with respect to the LIBOR Rate Loans as in effect on such day. The Borrowers also agree to pay, on demand, interest on any overdue amount (including any overdue interest) payable under this subsection (f), for each day from and including the date when such amount becomes due to but excluding the date such amount is paid in full, at a rate per annum equal to the sum of the Prime Rate for such day PLUS 2.0% (or, if such rate is unlawful, the highest rate permitted under applicable law). (g) EXCULPATORY PROVISIONS. The obligations of the Borrowers under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrowers may have or have had against the Bank, any beneficiary of any Letter of Credit or any other person. The Borrowers assume all risks of the acts or omissions of any beneficiary of any Letter of Credit with respect to the use of such Letter of Credit by such beneficiary. Neither the Bank nor any of its officers, directors, employees and agents shall be responsible for, and the obligations of the Borrowers to reimburse the Bank for drawings pursuant to this Section 3 (other than obligations resulting solely from the gross negligence or willful misconduct of the Bank) shall not be excused or affected by, among other things, (i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (ii) the validity, sufficiency or genuineness of documents presented under any Letter of Credit or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by the Bank against presentation of documents to it which do not comply with the terms of the relevant Letter of Credit; or (iv) any dispute between or among the Borrowers, any beneficiary of any Letter of Credit or any other person or any claims or defenses whatsoever of the Borrowers or any other person against any beneficiary of any Letter of Credit. The Bank 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. Any action taken or omitted by the Bank in connection with any Letter of Credit and the related drafts and documents, if done without willful misconduct or gross negligence, shall be binding on the Borrowers and shall not place the Bank under any liability to the Borrowers. (h) INDEMNIFICATION BY BORROWERS. Each of the Borrowers agrees to indemnify and hold harmless the Bank from and against any and all claims, damages, losses, liabilities, costs or expenses (including, without limitation, the reasonable fees and disbursements of counsel) which the Bank may reasonably incur (or which may be claimed against the Bank by any person whatsoever) by reason of or in connection with any execution and delivery or transfer of, or payment or failure to pay under, any Letter of Credit or any actual or proposed use of any Letter of Credit; provided that the Borrowers shall not be required to indemnify the Bank for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the Bank in determining whether a request presented under any Letter of Credit issued by it complied with the terms of such Letter of Credit or (ii) the Bank's failure to pay under any Letter of Credit issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Letter of Credit.

Each of the Borrowers is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of organization; is duly qualified to do business and in good standing in each jurisdiction in the United States of America where such qualification is required, except those jurisdictions where the failure to so qualify will not have a material adverse effect on the Borrowers' business, prospects or financial condition, taken as a whole (a list of the jurisdictions where the Borrowers are so qualified being set forth on Schedule 5(a) hereto); and has all requisite corporate power and authority to conduct its business as presently being conducted and as proposed to be conducted after the Closing and to own its properties now and after the Closing; and each of the Borrowers has all requisite corporate power and authority to execute and deliver, and to perform all of its obligations under, this Agreement and the other Loan Documents. (b) AUTHORITY. The execution, delivery and performance by each of the Borrowers of this Agreement and the other Loan Documents to which it is a party have been duly authorized by all necessary corporate action and do not contravene any provision of any of the Borrower's charter or by-laws; do not require any consents or approvals which have not been obtained (a list of any required consents and approvals is set forth on Schedule 5(b) hereto); do not violate any provision of any law, rule or regulation (including without limitation Regulations T, U and X of the Board of Governors of the Federal Reserve System) or any determination or award; do not and will not result in a breach or constitute a default under any agreement to which any of the Borrowers is a party or by which its properties are bound, including, without limitation, any indenture, loan or credit agreement, lease, debt instrument or mortgage; or result in or require the creation or imposition of any mortgage, deed of trust, pledge, lien, security interest or other charge or encumbrance of any nature upon or with respect to any of the Borrowers' properties; and none of the Borrowers is in material default under any law, rule or regulation, order, writ, judgment, injunction, decree, determination, award, indenture, loan or credit agreement, lease, debt instrument or mortgage referred to above or will not be in any such material default by virtue of the transactions to be entered into at the Closing. -22- (c) APPROVALS; COMPLIANCE WITH STATUTES, ETC. (i) No authorization, consent, approval, license or exemption of, or filing a registration with, any court or governmental department or commission, board, bureau, agency or instrumentality, domestic or foreign, is or will be necessary for the valid execution, delivery or performance by each of the Borrowers of this Agreement and the other Loan Documents to which it is a party, other than filings which have already been made and approvals which have already been received, a list of which is set forth on Schedule 5(c) hereto. Each of the Borrowers is the lawful holder of all licenses, permits, certificates and governmental authorizations required for the conduct of its business, except where the failure to hold any such licenses, permits, certificates or authorizations, individually or in the aggregate, would not have a material adverse effect on the business, prospects, property or financial condition of any of the Borrowers and their subsidiaries, taken as a whole. No such material license, permit, certificate or other governmental authorization has been revoked, cancelled, rescinded, modified, denied or lost and not reissued or reinstated, and none of the Borrowers has any reason to believe that any such material license, permit, certificate or other governmental authorization will be revoked, cancelled, rescinded, modified or lost.

Without limitation of the foregoing, each of the Borrowers and each of their subsidiaries is in compliance with, and neither the entering into of the Loan Documents or the use of the proceeds of the Loans will violate: any law, rule or regulation relating to anti-terrorism or money laundering, including the Anti-Terrorism Order, the Patriot Act, the Trading with the Enemy Act, as amended, or any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto. (d) VALID OBLIGATIONS.

In addition, all such policies satisfy the requirements set forth in Section 6(l) hereof. (h) LITIGATION AND OTHER PROCEEDINGS. Except as set forth on Schedule 5(h) hereto, there are no actions, suits or proceedings pending or threatened against any of the Borrowers before any court or any governmental department, commission, board, bureau, agency or instrumentality, and none of the actions, suits or proceedings listed on Schedule 5(h) could reasonably be expected to be materially adverse, either individually or in the aggregate, to the business, properties, financial condition or prospects of any of the Borrowers and their subsidiaries, taken as a whole. (i) LABOR MATTERS. Except as set forth on Schedule 5(i) hereto, none of the Borrowers is a party to any collective bargaining or similar agreement and each of the Borrowers has complied in all material respects with all applicable state and federal laws respecting employment and employment practices, terms and conditions of employment, wages and hours and other laws related to employment of employees of any such Borrower or its agents, and there are no arrears in the payment of wages, withholding or social security taxes, unemployment insurance premiums or other similar obligations of any of the Borrowers other than in the ordinary course of business. -24- (j) ERISA.

Other than as set forth on Schedule 5(q) hereto, none of such Consolidated Total Funded Debt is secured by any lien, encumbrance, mortgage, pledge, or security interest given by any of the Borrowers or any of their subsidiaries. (r) PATENTS, COPYRIGHTS AND TRADEMARKS. Except as set forth on Schedule 5(r), none of the Borrowers own any trademarks, copyrights or patents which are material in the ordinary course of business as each of the Borrowers' business is currently conducted or as such business is contemplated to be conducted in the future. -26- (s) REPRESENTATIONS ACCURATE.

If, under or from any circumstances whatsoever, fulfillment of any provision hereof or of any of the Loan Documents at the time of performance of such provision shall be due, shall involve transcending the limit of such validity prescribed by applicable law, then the obligation to be fulfilled shall automatically be reduced to the limits of such validity, and if under or from any circumstances whatsoever Bank should ever receive as interest an amount which would exceed the highest lawful rate, such amount which would be excessive interest shall be applied to the reduction of the principal balance evidenced hereby and not to the payment of interest. This provision shall control every other provision of all agreements between the Borrowers and the Bank. (g) EXECUTION. This Agreement may be signed in any number of counterparts, which together will be one and the same instrument. This Agreement shall become effective whenever each party shall have signed at least one such counterpart. (h) GOVERNING LAW. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts and for all purposes shall be construed in accordance with the laws of such Commonwealth. (i) FEES; INDEMNIFICATION. Whether or not any funds are disbursed hereunder, each of the Borrowers shall pay all of the Bank's reasonable costs and expenses in connection with the preparation, execution, delivery, review, administration and enforcement of this Agreement and the other Loan Documents, including reasonable legal fees and disbursements. Each of the Borrowers hereby agrees to indemnify and hold harmless the Bank from and against any and all claims, damages, losses, liabilities, costs or expenses (including, without limitation, the reasonable fees and disbursements of counsel) which the Bank may reasonably incur (or which may be claimed against the Bank by any person whatsoever) by reason of, in connection with or in any way related to this Agreement and the other Loan Documents or any of the transactions contemplated hereby or thereby; provided that the Borrowers shall not be required to indemnify the Bank for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent caused by gross negligence or willful misconduct of the Bank. -47- (j) BINDING NATURE. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns; provided that the rights and obligations under this Agreement and under any of the other Loan Documents may not be assigned by any of the Borrowers without the written consent of the Bank. (k) ASSIGNMENT; PARTICIPATIONS; PLEDGE TO FEDERAL RESERVE. (i) The Bank shall have the unrestricted right at any time or from time to time, and without any of the Borrowers' consent, to assign all or any portion of its rights and obligations hereunder to one or more banks or other financial institutions (each, an "ASSIGNEE"), after giving at least 15 Business Days prior written notice of such assignment to the Borrowers, and the Borrowers agree that it shall execute, or cause to be executed, such documents, including without limitation, amendments to this Agreement and to any other documents, instruments and agreements executed in connection herewith as Bank shall deem necessary to effect the foregoing. In addition, at the request of Bank and any such Assignee, the Borrowers shall issue one or more new promissory notes, as applicable, to any such Assignee and, if Bank has retained any of its rights and obligations hereunder following such assignment, to Bank, which new promissory notes shall be issued in replacement of, but not in discharge of, the liability evidenced by the promissory note held by Bank prior to such assignment and shall reflect the amount of the respective commitments and Loans held by such Assignee and Bank after giving effect to such assignment. Upon the execution and delivery of appropriate assignment documentation, amendments and any other documentation required by Bank in connection with such assignment, and the payment by Assignee of the purchase price agreed to by Bank and such Assignee, such Assignee shall be a party to this Agreement and shall have all of the rights and obligations of Bank hereunder (and under any and all other guaranties, documents, instruments and agreements executed in connection herewith) to the extent that such rights and obligations have been assigned by Bank pursuant to the assignment documentation between Bank and such Assignee, and Bank shall be released from its obligations hereunder and thereunder to a corresponding extent. -48- (ii) Bank shall have the unrestricted right at any time and from time to time, and without the consent of any of the Borrowers, after giving at least 15 Business Days prior written notice of such grant to the Borrowers, to grant to one or more banks or other financial institutions (each, a "PARTICIPANT") participating interests in the Bank's obligation to lend hereunder and/or any or all of the Loans held by Bank hereunder. In the event of any such grant by Bank of a participating interest to a Participant, the Bank shall remain responsible for the performance of its obligations hereunder and the Borrowers shall continue to deal solely and directly with Bank in connection with Bank's rights and obligations hereunder. (iii) The Bank may furnish any information concerning the Borrowers in its possession from time to time to prospective Assignees or Participants, provided that the Bank shall require any such prospective Assignee or Participant to agree in writing to maintain the confidentiality of such information. (iv) Notwithstanding any of the foregoing, the Bank may at any time pledge or assign all or any portion of its rights under the Loan Documents including any portion of the Amended and Restated Line of Credit Notes or the Term Note to any of the twelve (12) Federal Reserve Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or assignment or enforcement thereof shall release the Bank from its obligations under any of the Loan Documents. (l) UNDER SEAL. This Agreement shall be deemed to be an instrument under seal and shall continue in full force and effect so long as any indebtedness of any of the Borrowers to the Bank remains unpaid. (m) USE OF PROCEEDS. Borrowers (i) for working capital purposes of the Borrower, (ii) to refinance existing Indebtedness of the Borrowers, (iii) in the case of the Second Line of Credit, to fund acquisitions by the Borrower, to the extent permitted herein, and (iv) in the case of the Term Loan, to pay the outstanding balance under the Second Line of Credit on the Closing Date. No portion of the proceeds of any loans shall be used, and no portion of any Letter of Credit is to be obtained, in whole or in part, for the purpose of purchasing or carrying any "margin security" or "margin stock" as such terms are used in Regulations U, T or X of the Board of Governors of the Federal Reserve System. (n) CONFIDENTIALITY. Notwithstanding any confidentiality provisions contained herein, and in accordance with Section 1.6011-4(b)(3)(iii) of the Treasury Regulations, each party to this Agreement (and each employee, representative, or other agent of each party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure; provided, however, that, pursuant to Section 1.6011-4(b)(3)(ii) of the Treasury Regulations, such disclosure shall not be permitted to the extent, but only to the extent, such disclosure would reasonably be considered to result in noncompliance with the securities laws of any applicable jurisdiction. For the avoidance of doubt, the parties acknowledge and agree that the tax treatment and tax structure of any transaction does not include the name of any party to a transaction or any sensitive business information (including, without limitation, specific information about any party's intellectual property or other proprietary assets) unless such information may be related or relevant to the purported or claimed federal income tax treatment of the transaction. -49- If you agree with the terms of this Agreement, including the Exhibits attached hereto and the other documents referred to herein, please sign below where indicated in your capacity as President and Chief Executive Officer of the Borrower.
