ARTICLE 2- AGENTED BORROWINGS

     2-1. Designation of Agent Borrower. Each Borrower hereby designates the
Lead Borrower as the agent of that Borrower to discharge the duties and
responsibilities of the Lead Borrower as provided herein.

     2-2. Operation of Loan Arrangement.

     (a) Except as otherwise provided in this Article, Revolving Credit Loans
and requests for the issuance of L/Cs shall be requested solely by the Lead
Borrower as agent for each Borrower.

     (b) Any Revolving Credit Loan which may be made by the Lenders and which is
directed to the Lead Borrower is received by the Lead Borrower in trust for that
or those of the Borrowers who are intended to receive such advance. The Lead
Borrower shall distribute the proceeds of any such advances solely to the
Borrowers. Each Borrower shall be directly indebted to the Lenders for each
Revolving Credit Loan distributed to that Borrower by the Lead Borrower,
together with all accrued interest thereon, as if that amount had been advanced
directly by the Lenders to that Borrower (whether or not the subject advance was
based upon the accounts of the Borrower which actually received such
distribution), in addition to which each Borrower shall be obligated to the
Lenders in that amount on account of that Borrower's having guarantied the
Liabilities.

     (c) The Administrative Agent and the Lenders shall have no responsibility
to inquire as to the distribution of the Revolving Credit Loans made through the
Lead Borrower as described herein.

     2-3. Loans Directly to Borrower.

                                      -15-

<PAGE>

     (a) If, for any reason, and at any time during the term of this Agreement,
any Borrower, including the Lead Borrower as agent for the Borrowers, shall be
unable to, or prohibited from carrying out the terms and conditions of this
Agreement (as determined by the Administrative Agent in the Administrative
Agent's sole and absolute discretion), then the Lenders may make Revolving
Credit Loans directly to, and issue L/Cs directly for the account of, such of
the Borrowers as the Administrative Agent determines to be appropriate, which
Revolving Credit Loans or issuances of L/Cs may be made without regard to the
procedures otherwise included in this Article 2.

     (b) Each of the Borrowers shall remain liable to the Lenders for the joint
and several payment and performance of all Liabilities notwithstanding any
determination by the Administrative Agent to cease making Revolving Credit Loans
or issuing L/Cs to or for the benefit of any Borrower.

     2-4. Continuation of Authority of Lead Borrower. The authority of the Lead
Borrower to request Revolving Credit Loans on behalf of, and to bind, the
Borrowers, shall continue unless and until the Administrative Agent acts as
provided in Section 2-3, above, or the Administrative Agent actually receives(a)
written notice of: (i) the termination of such authority, and (ii) the
subsequent appointment of a successor Lead Borrower, which notice is signed by
the respective Responsible Officer of each Borrower then eligible for borrowing
under this Agreement; and

     (b) written notice from such successive Lead Borrower (i) accepting such
appointment; (ii) acknowledging that such removal and appointment has been
effected by the respective Responsible Officer of such Borrowers eligible for
borrowing under this Agreement; and (iii) acknowledging that, from and after the
date of such appointment, the newly appointed Lead Borrower shall be bound by
the terms hereof, and that as used herein, the term "Lead Borrower" shall mean
and include the newly appointed Lead Borrower.

     2-5. Concerning Joint and Several Liability of the Borrowers.

     (a) Each of the Borrowers is accepting joint and several liability
hereunder and under the other Loan Documents in consideration of the financial
accommodations to be provided by the Lenders and the Administrative Agent under
this Agreement, for the mutual benefit, directly and indirectly, of each of the
Borrowers and in consideration of the undertakings of each other Borrower to
accept joint and several liability for the Liabilities.

     (b) Each of the Borrowers, jointly and severally, hereby irrevocably and
unconditionally accepts, not merely as a surety but also as a co-debtor, joint
and several liability with the other Borrowers, with respect to the payment and
performance of all of the Liabilities (including, without limitation, any
Liabilities arising under this Section 2-5), it being the intention of the
parties hereto that all of the Liabilities shall be joint and several
obligations of each of the Borrowers, without preferences or distinction among
them.

     (c) If and to the extent that any of the Borrowers shall fail to make any
payment with respect to any of the Liabilities as and when due or to perform any
of the Liabilities in

                                      -16-

<PAGE>

accordance with the terms thereof, then in each such event the other Borrowers
will make such payment with respect to, or perform, such Liability.

     (d) The Liabilities of each of the Borrowers under the provisions of this
Section 2-5 constitute the full recourse Liabilities of each of the Borrowers
enforceable against each such Borrower to the full extent of its properties and
assets, irrespective of the validity, regularity or enforceability of this
Agreement or any other circumstance whatsoever.

     (e) Except as otherwise expressly provided in this Agreement, each of the
Borrowers hereby waives notice of acceptance of its joint and several liability,
notice of any Loans made or L/Cs issued under this Agreement, notice of the
occurrence of any Event of Default, or of any demand for any payment under this
Agreement, notice of any action at any time taken or omitted by any Lender or
the Administrative Agent under or in respect of any of the Liabilities, any
requirement of diligence or to mitigate damages and, generally, to the extent
permitted by applicable law, all demands, notices and other formalities of every
kind in connection with this Agreement. Each of the Borrowers hereby assents to,
and waives notice of, any extension or postponement of the time for the payment
of any of the Liabilities, the acceptance of any payment of any of the
Liabilities, the acceptance of any partial payment thereon, any waiver, consent
or other action or acquiescence by any Lender or the Administrative Agent at any
time or times in respect of any Event of Default by any of the Borrowers in the
performance or satisfaction of any term, covenant, condition or provision of
this Agreement, any and all other indulgences whatsoever by any Lender or the
Administrative Agent in respect of any of the Liabilities, and the taking,
addition, substitution or release, in whole or in part, at any time or times, of
any security for any of the Liabilities or the addition, substitution or
release, in whole or in part, of any of the Borrowers. Without limiting the
generality of the foregoing, each of the Borrowers assents to any other action
or delay in acting or failure to act on the part of any Lender or the
Administrative Agent with respect to the failure by any of the Borrowers to
comply with any of its respective Liabilities, including, without limitation,
any failure strictly or diligently to assert any right or to pursue any remedy
or to comply fully with applicable laws or regulations thereunder, which might,
but for the provisions of this Section 2-5, afford grounds for terminating,
discharging or relieving any of the Borrowers, in whole or in part, from any of
its Liabilities under this Section 2-5, it being the intention of each of the
Borrowers that, so long as any of the Liabilities hereunder remain unsatisfied,
the Liabilities of such Borrowers under this Section 2-5 shall not be discharged
except by performance and then only to the extent of such performance. The joint
and several liability of the Borrowers hereunder shall continue in full force
and effect notwithstanding any absorption, merger, amalgamation or any other
change whatsoever in the name, membership, constitution or place of formation of
any of the Borrowers, any Lender or any Agent.

     (f) The provisions of this Section 2-5 are made for the benefit of the
Lenders and the Administrative Agent and their respective successors and
assigns, and may be enforced by it or them from time to time against any or all
of the Borrowers as often as occasion therefor may arise and without requirement
on the part of the Lenders or the Agent or such successor or assign first to
marshall any of its or their claims or to exercise any of its or their rights
against any of the other Borrowers or to exhaust any remedies available to it or
them against any of the other Borrowers or to resort to any other source or
means of obtaining payment of any of the

                                      -17-

<PAGE>

Liabilities hereunder or to elect any other remedy. The provisions of this
Section 2-5 shall remain in effect until all of the Liabilities shall have been
paid in full or otherwise fully satisfied. If at any time, any payment, or any
part thereof, made in respect of any of the Liabilities, is rescinded or must
otherwise be restored or returned by any Lender or the Agent upon the
insolvency, bankruptcy or reorganization of any of the Borrowers, or otherwise,
the provisions of this Section 2-5 will forthwith be reinstated in effect, as
though such payment had not been made.

     (g) Each of the Borrowers hereby agrees that it will not enforce any of its
rights of contribution or subrogation against the other Borrowers with respect
to any liability incurred by it hereunder or under any of the other Loan
Documents, any payments made by it to any of the Lenders or the Agent with
respect to any of the Liabilities or any collateral security therefor until such
time as all of the Liabilities have been irrevocably paid in full in cash. Any
claim which any Borrower may have against any other Borrower with respect to any
payments to the Lenders or the Agent hereunder or under any other Loan Documents
are hereby expressly made subordinate and junior in right of payment, without
limitation as to any increases in the Liabilities arising hereunder or
thereunder, to the prior payment in full of the Liabilities and, in the event of
any insolvency, bankruptcy, receivership, liquidation, reorganization or other
similar proceeding under the laws of any jurisdiction relating to any Borrower,
its debts or its assets, whether voluntary or involuntary, all such Liabilities
shall be paid in full before any payment or distribution of any character,
whether in cash, securities or other property, shall be made to any other
Borrower therefor.

     (h) Each of the Borrowers hereby agrees that the payment of any amounts due
with respect to the Indebtedness owing by any Borrower to any other Borrower is
hereby subordinated to the prior payment in full in cash of the Liabilities.
Each Borrower hereby agrees that after the occurrence and during the continuance
of any Default or Event of Default, such Borrower will not demand, sue for or
otherwise attempt to collect any Indebtedness of any other Borrower owing to
such Borrower until the Liabilities shall have been paid in full in cash. If,
notwithstanding the foregoing sentence, such Borrower shall collect, enforce or
receive any amounts in respect of such Indebtedness, such amounts shall be
collected, enforced and received by such Borrower as trustee for the Agent and
be paid over to the Agent for the pro-rata accounts of the Lenders to be applied
to repay the Liabilities.

     2-6. Indemnification. The Lead Borrower and each Borrower respectively
shall indemnify, defend, and save and hold the Administrative Agent and each
Lender harmless from and against any liabilities, claims, demands, expenses, or
losses made against or suffered by the Administrative Agent or any Lender on
account of, or arising out of, the Loans, the Administrative Agent and each
Lenders' reliance upon loan requests made by the Lead Borrower, or any other
action taken by the Administrative Agent and each Lender hereunder or under any
of the Loan Documents, except for any liability, claim, demand, expense, or loss
as to which a final judicial determination is made and from which no appeal is
available (in a proceeding in which the Administrative Agent and each Lender has
had an opportunity to be heard) that the Administrative Agent or any Lender had
acted in a grossly negligent manner, in actual bad faith or with willful
misfeasance.

ARTICLE 3 - THE REVOLVING CREDIT/LIBOR PROVISIONS

     3-1. Establishment of Revolving Credit.

     (a) The Lenders hereby establish a revolving line of credit (hereinafter,
the "REVOLVING CREDIT") in the Borrowers' favor pursuant to which each Lender,
subject to, and in accordance with, this Agreement, severally agrees to make
Revolving Credit Loans and issue L/Cs and otherwise provide financial
accommodations to and for the account of the Borrowers, in each instance up to
the amount of such Lender's Commitment Percentage of Availability, but in no
event exceeding the maximum amount of such Lender's Commitment. The amount
available for borrowing under the Revolving Credit shall be determined by the
Lenders by reference to Availability, as determined by the Lenders from time to
time hereafter.

     (b) As used herein, the term "AVAILABILITY" refers at any time to up to:

               (A) the Revolving Loan Ceiling

               Minus

               (B) The then unpaid principal balance of the Loan Account

               Minus

               (C) The aggregate amounts then undrawn on all outstanding L/C's,
          acceptances or any other accommodations issued or incurred, or caused
          to be issued or incurred, by the Lenders for the account and/or the
          benefit of any of the Borrowers.

     (c) The proceeds of borrowings under the Revolving Credit shall be utilized

     Revolving Credit while any Suspension Event has occurred and is continuing.

          (ii) Any delay in the proceeds of any such Revolving Credit Loan
     constituting collected funds.

          (iii) Any delay in the receipt, and/or any loss, of funds which

     initiated by the Administrative Agent in accordance with wire instructions
     provided to the Administrative Agent by the Lead Borrower.

     (e) The Administrative Agent may rely on any request for a Revolving Credit
Loan or financial accommodation which the Administrative Agent, in good faith,
believes to have been made by a Person duly authorized to act on behalf of the
Lead Borrower and may decline to make any such requested Revolving Credit Loan
or to provide any such financial accommodation pending the Administrative
Agent's being furnished with such documentation concerning that Person's
authority to act as may be satisfactory to the Administrative Agent.

     (f) A request by the Lead Borrower for any financial accommodation under
the Revolving Credit or of the issuance of an L/C or any other accommodations
shall be irrevocable and shall constitute certification by the Lead Borrower and
each Borrower that as of the date of such request, each of the following is true
and correct:

          (i) There has been no Material Adverse Change in the Borrowers'
     financial condition taken as a whole, from the most recent financial

designated by the Administrative Agent or (B) written notice.

          (ii) The Administrative Agent, in the Administrative Agent's

          thereof, would not exceed the Availability;

               (B) the L/C (if so issued) is in form satisfactory to the
          Administrative Agent;

advance under the Revolving Credit any amount which any Borrower is obligated to
pay to the Administrative Agent or for which any Borrower or the Administrative
Agent becomes obligated on account of, or in respect to, any L/C. Such advance
shall be made even if such advance would result in Availability's being
exceeded. Such action on the part of the Administrative Agent shall not
constitute a waiver by the Administrative Agent or any Lender of its rights
under Section 3-4(e) below.

     (j) Upon the occurrence from time to time of any Suspension Event:

                                      -21-

Percentage of such Revolving Credit Loan requested by the Lead Borrower, and the
Administrative Agent shall promptly advance such amounts to the Lead Borrower in
accordance with the terms hereof.

     3-4. The Loan Account.

     (a) An account (hereinafter, the "LOAN ACCOUNT") shall be opened on the
books of the Administrative Agent, in which Loan Account a record may be kept of
all Revolving Credit Loans made by the Lenders to the Borrowers under or
pursuant to the Revolving Credit and of all payments thereon.

     (b) The Administrative Agent may also keep a record (either in the Loan
Account or elsewhere, as the Administrative Agent may from time to time elect)
of all interest, fees, service charges, costs, expenses, and other debits owed
the Administrative Agent and each Lender on account of the Liabilities under the
Revolving Credit and of all credits against such amounts so owed.

     (c) All credits against the Liabilities shall be conditional upon final
payment to the Administrative Agent of the items giving rise to such credits.
The amount of any item credited against the Liabilities which is charged back
against the Administrative Agent for any reason or is not so paid shall be a
Liability and shall be added to the Loan Account, whether or not the item so
charged back or not so paid is returned.

     (d) Except as otherwise provided herein, all fees, service charges, costs,
and expenses for which the Borrowers are obligated hereunder are payable within
thirty (30) days of notice from the Administrative Agent to the Lead Borrower.

advance under the Revolving Credit any interest, fee, service charge, or other
payment to which

                                      -22-
<PAGE>

the Administrative Agent or any Lender is entitled from any Borrower pursuant
hereto and may charge the same to the Loan Account notwithstanding that such
amount so advanced may result in Availability's being exceeded. Any amount which
is added to the principal balance of the Loan Account as provided in this
Subsection shall bear interest at the interest rate applicable from time to time
to the unpaid principal balance of the Loan Account.

     (f) Any statement rendered by the Administrative Agent to the Lead Borrower
concerning the Liabilities shall be considered correct and accepted by the
Borrowers and shall be conclusively binding upon the Borrowers unless the Lead
Borrower provides the Administrative Agent with written objection thereto within
sixty (60) days from the mailing of such statement, which written objection
shall indicate, with particularity, the reason for such objection. The Loan
Account and the Administrative Agent's books and records concerning the loan
arrangement contemplated herein and the Liabilities shall be prima facie
evidence and proof of the items described therein.

     3-5. The Revolving Credit Note. The obligation to repay Revolving Credit
Loans, with interest as provided herein, shall be evidenced by certain notes
(hereinafter, collectively, the "REVOLVING CREDIT NOTE") payable to each Lender
in a principal amount equal to such Lender's Commitment Percentage of the
Revolving Credit, in the form of EXHIBIT 3-5, annexed hereto, executed by each
Borrower in favor of such Lender. Neither the original nor a copy of any
Revolving Credit Note shall be required, however, to establish or prove any
Liability on account thereof. In the event that a Revolving Credit Note is ever
lost, mutilated, or destroyed, the Borrowers shall execute a replacement thereof
and deliver such replacement to the subject Lender, subject to such Lender
providing a commercially reasonable indemnity in connection therewith.

     3-6. Payment of Loan Account.

Account and all other Liabilities on the Termination Date (as to which, see
Article 11, below).

or, at the Lead Borrower's option in accordance with the terms hereof, the LIBOR
Rate, as specified from time to time by the Lead Borrower in the
Renewal/Conversion Notice with respect to the subject Revolving Credit Loan or
as otherwise provided in this Agreement.

     (b) The Borrowers shall pay interest on each Revolving Credit Loan in
arrears on the applicable Interest Payment Date for that Loan and on the
Termination Date.

     (c) Following the occurrence and during the continuance of any Event of
Default (and whether or not the Lenders exercise their rights on account
thereof), upon notice from the

                                      -23-

<PAGE>

Administrative Agent to the Lead Borrower, the outstanding principal balance of
the Revolving Credit Loans shall bear interest at a rate per annum equal to the
rate (including the Base Rate Margin or the LIBOR Margin, as applicable) in
effect from time to time plus two and 00/100 percent (2.00%) per annum.

     3-8. Duration of Interest Periods.

     (a) Subject to the limitation described herein, the Lead Borrower shall
have the option to elect an Interest Period to be applicable to a Revolving
Credit Loan by giving notice of such election (a "RENEWAL/CONVERSION NOTICE") in
the form of EXHIBIT 3-8, annexed hereto received no later than 10:00 Boston time
one (1) Business Day before the end of the then applicable Interest Period if
such Loan is to be converted to a Base Margin Loan and three (3) Business Days
before (and not counting) the end of the then applicable Interest Period if such
Loan is to be continued as, or converted to, a LIBOR Loan; provided, however,
that (a) any Conversion of LIBOR Loans may be made only on the last day of the
respective Interest Period for such Loans, and (b) no loan may be Converted to a
LIBOR Loan when any Event of Default has occurred and is continuing. Each such
Conversion Request shall be by telephone, telecopy, electronic mail, telex or
cable, in each case confirmed immediately in writing in the manner specified for
notices herein, and shall, within the restrictions specified above, specify (i)
the date of such Conversion, (ii) the Loans to be Converted, and (iii) if such
Conversion is to LIBOR Loan the duration of the initial Interest Period for such
Loans. Each Conversion Request with respect to LIBOR Loans shall be irrevocable
and binding on the Borrowers.

     (b) If the Administrative Agent does not receive a notice of election of,
or conversion to, an Interest Period for a LIBOR Loan pursuant to subsection (a)
within the applicable time limits specified therein, the Lead Borrower shall be
deemed to have elected to convert such Loan in whole into a Base Margin Loan on
the last day of the then current Interest Period with respect thereto.

     (c) The Lead Borrower shall not select, renew, or convert any Revolving
Credit Loan such that there are more than six (6) interest rates applicable to
the Revolving Credit Loans in the aggregate which are LIBOR Loans at any one
time.

     (d) LIBOR Loans shall each be in an amount of not less than Five Hundred
Thousand and no/100 Dollars ($500,000.00) and Five Hundred Thousand and no/100
Dollars ($500,000.00) increments in excess of such minimum.

     (e) If, after giving a Conversion Request, the Lead Borrower fails to
borrow or Convert any LIBOR Loan, the Lead Borrower shall indemnify the
Administrative Agent and each Lender against any loss or expense incurred by the
Administrative Agent and each Lender as a result of such failure, including,
without limitation, any loss or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or
maintain a LIBOR Loan to be made by such Lender and the compensation as provided
for in Section 3-15, herein.

     3-9. Changed Circumstances. In the event that:

                                      -24-

<PAGE>

     (a) On any day on which the rate for a LIBOR Loan would otherwise be set,
the Administrative Agent shall have determined in good faith (which
determination shall be final and conclusive) that adequate and fair means do not
exist for ascertaining either such rate; or

     (b) At any time that the Administrative Agent shall have determined in good
faith (which determination shall be final and conclusive) that:

          (i) the continuation of or conversion of any Revolving Credit Loan to
     a LIBOR Loan has been made impracticable or unlawful by (A) the occurrence
     of a contingency that materially and adversely affects the applicable
     market or (B) compliance by any Lender in good faith with any applicable
     law or governmental regulation, guideline or order or interpretation or
     change thereof by any governmental authority charged with the
     interpretation or administration thereof or with any request or directive
     of any such governmental authority having the force of law; or

          (ii) the indices on which the interest rates for LIBOR Loans shall no
     longer represent the effective cost to the Lenders for U.S. dollar deposits
     in the interbank market for deposits in which they regularly participate;

     then, and in any such event, the Administrative Agent shall forthwith so
     notify the Lead Borrower thereof. Until the Administrative Agent notifies
     the Lead Borrower that the circumstances giving rise to such notice no
     longer apply, the obligation of the Lenders to make LIBOR Loans of the type
     affected by such changed circumstances or to permit the Lead Borrower to
     select the affected interest rate as otherwise applicable to any Revolving
     Credit Loans shall be suspended. If at the time the Administrative Agent so
     notifies the Lead Borrower, the Lead Borrower has previously given the
     Administrative Agent a Renewal/Conversion Notice with respect to one or
     more LIBOR Loans, but such LIBOR Loans have not yet gone into effect, such
     notification shall be deemed to be void and the Lead Borrower may only
     borrow Base Margin Loans and shall furnish a substitute Renewal/Conversion
     Notice. Upon the expiration of the Interest Period for any LIBOR Loan which
     is outstanding on the date of such notification, the amount of such LIBOR
     Loan shall thereafter constitute a Base Margin Loan.

     3-10. Payments and Prepayments.

     (a) Base Margin Loans may be prepaid at any time and from time to time
without premium or penalty.

     (b) Any LIBOR Loan may be prepaid, upon not less than three (3) Business
Days' prior written notice to the Administrative Agent, without penalty,
provided that (1) each partial prepayment shall be in the principal amount of
$500,000.00 or an integral multiple thereof, (2) if such prepayment is on any
day other than the last day of the Interest Period relating thereto, such amount
prepaid shall be accompanied by any additional amounts necessary to compensate
the Lenders for any costs incurred by the Lenders in accordance with Section
3-15, herein, including any interest or fees payable by the Lenders to lenders
of funds obtained by them in order to make

                                      -25-

<PAGE>

or maintain its LIBOR Loans hereunder and (3) any amount prepaid shall be
accompanied by accrued interest on the principal repaid to the date of payment.

     (c) In the event that at the time of any such prepayment Loans are
outstanding of more than one type, the amount prepaid shall be applied first to
any Base Margin Loan prior to application to any LIBOR Loans.

     (d) Any premium due hereunder upon such prepayment shall be due and payable
upon any prepayment whatsoever, whether voluntary or involuntary, to the extent
permitted by law, and after acceleration of the unpaid principal balance of the
Liabilities after the occurrence and during the continuance of an Event of
Default.

     3-11. Fees.

     (a) As compensation for the Lenders' commitment included herein to make
loans and advances to the Borrowers and as compensation for the Lenders'
maintenance of sufficient funds available for such purpose, the Lenders shall
have earned a FACILITY FEE (so referred to herein) of $30,000.00 (to be shared
by the Lenders as agreed among the Lenders).

     (b) In addition to any other fee by the Borrowers on account of the
Revolving Credit, the Borrowers shall pay to the Administrative Agent, for the
pro rata benefit of the Lenders, a LINE (UNUSED) FEE (so referred to herein) in
arrears, on the first day of each quarter (or relevant pro rata portion thereof)
(and on the Termination Date). The Line (Unused) Fee shall be equal to the Line
Fee Percentage of the average difference, during the quarter just ended (or
relevant period with respect to the payment being made on the Termination Date)
between the Revolving Loan Ceiling and the unpaid principal balance of the Loan
Account.

     (c) In addition to any other fee by the Borrowers on account of the
Revolving Credit, the Borrowers shall pay the Administrative Agent, for its own
account, an annual fee (the "ANNUAL FEE") of $20,000.00 payable on September 1,
2006 and each anniversary thereof.

     (d) The Borrower shall not be entitled to any credit, rebate or repayment
of any Facility Fee, Annual Fee or Line (Unused) Fee previously earned by the
Administrative Agent or the Lenders pursuant to this Section notwithstanding any
termination of this Agreement or suspension or termination of the Lenders'
obligation to make Loans and advances hereunder.

     3-12. Fees For L/C's.

     (a) Prior to the issuance of any L/C, the Borrowers shall pay to the
Administrative Agent, for the pro rata benefit of the Lenders, a fee on account
of such L/C based upon the Administrative Agent's then current fee schedule for
like L/C's.

     (b) In addition to the fee to be paid as provided in Subsection (a), above,
the Borrowers shall pay to the Administrative Agent, on demand, all issuance,
processing, negotiation, amendment, and administrative fees and other amounts on
account of, or in respect to, each L/C.

                                      -26-

<PAGE>

     3-13. Effect of Honor of L/C's. The Borrowers shall reimburse the
Administrative Agent for the amount of any honoring of any L/C. Any such
honoring which is not so reimbursed on the Business Day when so honored shall
constitute a Revolving Credit Loan.

     3-14. Additional Provisions Relating to L/C's.

     (a) The obligations of the Borrowers with respect to L/Cs shall be absolute
and unconditional. The obligations of the Borrowers with respect to L/Cs shall
rank pari passu with the obligations of the Borrowers to repay all other
Liabilities. The Borrowers, the Administrative Agent and the Lenders acknowledge
and agree that all Existing L/Cs shall be deemed L/Cs issued pursuant to this
Agreement. The Administrative Agent's rights, powers, privileges and immunities
specified in or arising under this Agreement with respect to L/C's are in
addition to any heretofore or at any time hereafter otherwise created or
arising, whether by statute or rule of law or contract.

     (b) The Borrowers will

          (i) promptly examine the copy of any L/C (and any amendments thereof)
     sent to it by the Administrative Agent;

          (ii) promptly examine all instruments and documents delivered to it
     from time to time by the Administrative Agent; and

          (iii) within three (3) Business Days of receipt thereof, provide the
     Administrative Agent with written notice of any irregularity or claim of
     non-compliance with the instructions of such person or entity.

The Borrowers are conclusively deemed to have waived any such claim against the
Administrative Agent and its correspondents unless such notice is so timely
given.

     (c) The Borrowers will

          (i) procure promptly any necessary documentation, permits, or licenses
     for the import, export or shipping of the property in connection with which
     any L/C is issued;

          (ii) comply with all foreign and domestic governmental requirements
     relating to the shipment or financing of such property; and

          (iii) furnish such evidence that the above-noted requirements have
     been fulfilled as the Administrative Agent reasonably may require.

     (d) The Borrowers will jointly and severally indemnify the Administrative
Agent and each Lender for and hold harmless against any and all claims, loss,
liability, or damage, including attorneys' reasonable fees, howsoever arising
from or in connection with the surrender or endorsement of any bill of lading,
warehouse receipt or documents of title at any time held by the Administrative
Agent, or any of its correspondents in connection with any L/C.

                                      -27-

<PAGE>

     (e) None of the Administrative Agent's correspondents or any advising,
negotiating, or paying bank with respect to any L/C, shall be responsible in any
way for:

          (i) performance by any beneficiary under any L/C of that beneficiary's
     or payee's obligations to any Borrower; or

          (ii) the form, sufficiency, correctness, genuineness, authority of any
     person signing, falsification, or the legal effect of, any documents called
     for under any L/C if (with respect to the foregoing) such documents on
     their face appear to be in order.

     (f) The Administrative Agent may honor, as complying with the terms of any
L/C and of any drawing thereunder, any drafts or other documents otherwise in
order, but signed or issued by an administrator, executor, conservator, trustee
in bankruptcy, debtor in possession, assignee for the benefit of creditors,
liquidator, receiver, or other legal representative of the party authorized
under such L/C to draw or issue such drafts or other documents.

     (g) Unless otherwise agreed to, in the particular instance, the Borrowers
hereby authorize the Administrative Agent to (i) select an advising bank, if
any; (ii) select a paying bank, if any; and (iii) select a negotiating bank.

     (h) All directions, correspondence, and funds transfers relating to any L/C
are at the risk of the Borrowers. The Administrative Agent shall have discharged
its obligations under any L/C which, or the drawing under which, includes
payment instructions, by the initiation of the method of payment called for in,
and in accordance with, such instructions (or by any other commercially
reasonable and comparable method). The Administrative Agent does not assume any
responsibility for any inaccuracy, interruption, error, or delay in transmission
or delivery by post, telegraph or cable, or for any inaccuracy of translation.

     (i) The Administrative Agent's rights, powers, privileges and immunities
specified in or arising under this Agreement are in addition to any heretofore
or at any time hereafter otherwise created or arising, whether by statute or
rule of law or contract.

     (j) Except to the extent otherwise expressly provided hereunder or agreed
to in writing by the Administrative Agent, and the Borrowers, the L/C will be
governed by the Uniform Customs and Practice for Documentary Credits,
International Chamber of Commerce, Publication No. 500, and any subsequent
revisions thereof.

     (k) If any change in any law, executive order or regulation, or any
directive of any administrative or governmental authority (whether or not having
the force of law), or in the interpretation thereof by any court or
administrative or governmental authority charged with the administration
thereof, shall either:

          (i) impose, modify or deem applicable any reserve, special deposit or
     similar requirements against L/C's heretofore or hereafter caused to be
     issued by the Administrative Agent or any Lender or with respect to which
     the Administrative Agent or any Lender has an obligation to lend to fund
     drawings thereunder; or

                                      -28-

<PAGE>

          (ii) impose on Administrative Agent or any Lender any other condition
     or requirements relating to any such L/C's;

and the result of any event referred to in clause (i) or (ii), above, shall be
to increase the cost to such Person of issuing or maintaining any L/C, then,
upon demand by such Person and delivery by such Person to the Lead Borrower of a
certificate of an officer of such Person describing such change in law,
executive order, regulation, directive, or interpretation thereof, its effect on
such Person, and the basis for determining such increased costs and their
allocation, the Borrowers within five (5) Business Days after receipt of such
notice shall pay to such Person, from time to time as specified by such Person,
such amounts as shall be sufficient to compensate such Person for such increased
cost. The Administrative Agent's or such Lender's determination of costs
incurred under clause (k) (i) or (ii) above, shall be conclusive and binding on
the Borrowers in the absence of manifest error.

     (l) The obligations of the Borrowers under this Agreement with respect to
L/C's are absolute, unconditional, and irrevocable and shall be performed
strictly in accordance with the terms hereof under all circumstances, whatsoever
including, without limitation, the following:

          (i) Any lack of validity or enforceability or restriction, restraint,
     or stay in the enforcement of this Agreement, any L/C, or any other
     agreement or instrument relating thereto.

          (ii) Any amendment or waiver of, or consent to the departure from, all
     or any of the above.

          (iii) The existence of any claim, set-off, defense, or other right
     which the Borrowers may have at any time against the beneficiary of the
     L/C.

     3-15. Indemnification. Each Borrower jointly and severally agrees to
indemnify the Administrative Agent and each Lender and to hold the
Administrative Agent and each Lender (each an "INDEMNIFIED PARTY") harmless from
and against any loss, cost or expense (including loss of anticipated profits)
that an Indemnified Party may sustain or incur as a consequence of (a) default
by the Borrowers in payment of the principal amount of or any interest on any
LIBOR Loans as and when due and payable, including any such loss or expense
arising from interest or fees payable by an Indemnified Party to lenders of
funds obtained by it in order to maintain its LIBOR Loans, (b) default by the
Borrowers in making a borrowing or conversion after the Lead Borrower has given
(or is deemed to have given) a Conversion Request, or (c) the making of any
payment of any LIBOR Loan or the making of any conversion of any such Loan to a
Base Margin Loan on a day that is not the last day of the applicable Interest
Period with respect thereto, whether due to voluntary prepayment, payment
realized from any guarantor after the occurrence of an Event of Default, or
otherwise, including interest or fees payable by an Indemnified Party to lenders
of funds obtained by it in order to maintain any such Loans. Such loss shall
include, without limitation, an amount calculated as follows:

     (a) First, the Indemnified Party shall determine the amount by which (i)
the total amount of interest which would have otherwise accrued hereunder on
each installment of

                                      -29-

<PAGE>

principal so paid or not borrowed, during the period beginning on the date of
such payment or failure to borrow and ending on the date such installment would
have been due (the "REEMPLOYMENT PERIOD"), exceeds (ii) the total amount of
interest which would accrue, during the Reemployment Period, on any readily
marketable bond or other obligation of the United States of America designated
by the Indemnified Party in its sole discretion at or about the time of such
payment, such bond or other obligation of the United States of America to be in
an amount equal (as nearly as may be) to the amount of principal so paid or not
borrowed and to have a maturity comparable to the Reemployment Period, and the
interest to accrue thereon to take account of amortization of any discount from
par or accretion of premium above par at which the same is selling at the time
of designation. Each sum amount is hereafter referred to as an "INSTALLMENT
AMOUNT".

     (b) Second, each Installment Amount shall be treated as payable as of the
date on which the related principal installment would have been payable by the
Borrowers had such principal installment not been prepaid or not borrowed.

     (c) Third, the amount to be paid on each such date shall be the present
value of the Installment Amount determined by discounting the amount thereof
from the date on which such Installment Amount is to be treated as payable, at
the same annual interest rate as that payable upon the bond or other obligation
of the United States of America designated as aforesaid by the Indemnified
Party.

     3-16. Computation of Interest and Fees. Interest and all fees payable on
account of the Liabilities shall be computed daily on the basis of a year of 360
days and paid for the actual number of days for which due. If the due date for
any payment of principal is extended by operation of law, interest shall be
payable for such extended time. If any payment required by this Agreement or any
other Loan Document becomes due on a day that is not a Business Day, such
payment may be made on the next succeeding Business Day (or prior Business Day
in connection with a LIBOR Loan), and such extension shall be included in
computing interest in connection with such payment.

     3-17. Automatic Payment. The Borrowers authorize the Administrative Agent
to automatically debit the Borrowers' demand deposit accounts with the
Administrative Agent on the Interest Payment Date or such other dates when due
for all principal, interest, fees, costs, commissions, service charges and
expenses due to the Lenders on account of the Liabilities.

     3-18. Additional Costs, Etc.. If any present or future applicable law,
which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Lender by any central bank or other fiscal, monetary or
other authority (whether or not having the force of law), shall:

                                      -30-

<PAGE>

     (a) subject any Lender to any tax, levy, impost, duty, charge, fee,
deduction or withholding of any nature with respect to this Agreement, the other
Loan Documents, or the Loans (other than taxes based upon or measured by the
income or profits of the Lender), or

     (b) materially change the basis of taxation (except for changes in taxes on
income or profits) of payments to any Lender of the principal of or the interest
on any Loans or any other amounts payable to the Lender under this Agreement or
the other Loan Documents, or

     (c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this Agreement) any special deposit,
reserve, assessment, liquidity, capital adequacy or other similar requirements
(whether or not having the force of law) against assets held by, or deposits in
or for the account of, or loans by, or commitments of an office of the Lender,
or

     (d) impose on any Lender any other conditions or requirements with respect
to this Agreement, the other Loan Documents, the Loan, or any class of loans or
commitments of which any Loan forms a part;

     and the result of any of the foregoing is

          (i) to increase the cost to any Lender of making, funding, issuing,
     renewing, extending or maintaining any of the Loans, or

          (ii) to reduce the amount of principal, interest or other amount
     payable to any Lender hereunder on account of any of the Loans, or

          (iii) to require any Lender to make any payment or to forego any
     interest or other sum payable hereunder, the amount of which payment or
     foregone interest or other sum is calculated by reference to the gross
     amount of any sum receivable or deemed received by such Lender from the
     Borrowers hereunder,

     then, and in each such case, the Borrowers will, upon demand made by such
     Lender at any time and from time to time and as often as the occasion
     therefor may arise, pay to such Lender such additional amounts as will be
     sufficient to compensate such Lender for such additional cost, reduction,
     payment or foregone interest or other sum, provided such Lender furnishes
     the Lead Borrower and the Administrative Agent with a copy of such request
     together with an explanation therefor and such Lender makes such request
     consistent with its practices relative to similar borrowers.

     3-19. Capital Adequacy. If any Lender shall have determined that the
adoption of any applicable law, rule, regulation, guideline, directive or
request (whether or not having force of law) regarding capital requirements, or
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender with any of the foregoing
imposes or increases a requirement by such Lender to allocate capital resources
to the Loans made, or to be made, hereunder, which has or would have the effect
of reducing the return on such Lender's capital to a level below that which such
Lender could have achieved (taking into consideration

                                      -31-

<PAGE>

such Lender's then existing policies with respect to capital adequacy and
assuming full utilization of such Lender's capital) but for such adoption,
change or compliance, by any amount deemed by such Lender to be material: (i)
such Lender shall promptly after its commercially reasonable determination of
such occurrence give notice thereof to the Lead Borrower together with an
explanation therefor; and (ii) the Borrowers shall pay to such Lender as an
additional fee from time-to-time on demand such amount as the Lender certifies
to be the amount that will compensate it for such reduction. In determining such
amounts, such Lender may use any reasonable averaging and attribution methods.

     3-20. Lenders' Commitments. (a) The obligations of each Lender are several
and not joint. No Lender shall have any obligation to make any Revolving Credit
Loan in excess of the lesser of the following:

          (i) that Lender's Commitment Percentage of the subject Revolving
     Credit Loan or of Availability,

          (ii) that Lender's Commitment of the Revolving Credit.

     (b) No Lender shall have any liability to the Borrowers on account of the
failure of any other Lender to provide any Revolving Credit Loan nor any
obligation to make up any shortfall which may be created by such failure.

     3-21. Replacement Lenders. In the event that the Borrowers become obligated
to pay additional amounts or increased amounts to, or receive notice from, any
Lender pursuant to Sections 3-9, 3-18 or 3-19 hereof (an "AFFECTED LENDER"),
then, unless such Affected Lender has theretofore removed or cured the
conditions which resulted in the obligation to pay such additional amounts or
increased amounts, and so long as no Event of Default then exists, the Borrowers
may, on thirty (30) Business Day's prior written notice from the Lead Borrower
to the Administrative Agent and the Affected Lender, cause the Affected Lender
to (and such Affected Lender shall) assign without recourse, such Affected
Lender's Commitment at such time together with all accrued but unpaid interest
and fees to either (x) another Lender willing to accept such assignment, or (y)
to an Eligible Assignee, to the extent available, in each instance pursuant to
the provisions of Section 13-13 below. Each of the Administrative Agent and the
Affected Lender shall reasonably cooperate with the Lead Borrower, without
recourse to either such Person, in effectuating the replacement of such Affected
Lender under this Section. The exercise by the Borrowers of their rights under
this Section shall be at the Borrowers' sole cost and expense and at no cost or
expense to the Administrative Agent, the Affected Lender or any of the other
Lenders. The terms of this Section shall not in any way limit the Borrowers'
obligation to pay to any Affected Lender compensation owing to such Affected
Lender pursuant to Section 3-18 or 3-19.

Borrowers, or take any other action that the Administrative Agent may deem
necessary or desirable to repair, insure, maintain or preserve any such

<PAGE>

undertake any of the foregoing and shall have no liability on account of any
action so undertaken except where there is a specific finding in a judicial
proceeding (in which the Administrative Agent has had an opportunity to be
heard), from which finding no further appeal is available, that Administrative
Agent had acted in actual bad faith or in a grossly negligent manner. Each
Borrower shall pay to the Administrative Agent, on demand, or the Administrative
Agent, in its discretion, may add to the Loan Account, all amounts paid or
incurred by the Administrative Agent pursuant to this section. The obligation of
the Borrowers to pay such amounts is a Liability.

     (a) All annual and quarterly financial statements of the Borrowers
furnished to the Lenders by the Borrowers for any period ending on or after
December 31, 2005 have been prepared in accordance with GAAP consistently
applied and present fairly the condition of the Borrowers at the date(s) thereof
and the results of operations and cash flows for the period(s) covered, except
that quarterly financial statements remain subject to year-end adjustments and
the addition of notes. There has been no change in the financial condition,
results of operations, or cash flows of the Borrowers since the date(s) of such
financial statements, other than changes in the ordinary course of business,
which changes have not been materially adverse, either singularly or in the
aggregate.

     (b) The Borrowers do not have any contingent obligations or obligation
under any Lease or Capital Lease which is not noted in the Borrowers' financial
statements furnished to the Lenders or has been otherwise disclosed in writing
to the Lenders prior to the execution of this Agreement.

of the Liabilities in connection with the Lenders' execution of this Agreement
contains or will contain any untrue statement of a material fact or omits or
will omit to state a material fact necessary in order to make the statements
therein not misleading. Except as set forth on EXHIBIT 4-14, there is no fact
known to any Borrower which has resulted in, or which, in the foreseeable future
could result in, a Material Adverse Change on the financial condition of any
Borrower or any such guarantor which has not been disclosed in writing to the
Lenders.

     5-28. Government Contracts. Each Government Contract is valid, binding and
in full force and effect, and, other than as set forth on EXHIBITS 4-14 OR 5-28,
there is no event which has occurred or exists, which constitutes or which with
notice, the happening of any event and/or the passage of time, would constitute,
a default or breach under any Government Contract or would cause the
acceleration of any obligation of any party thereto or give rise to any right of
termination or cancellation thereof. Except as set forth on EXHIBITS 4-14 OR
5-28, the Borrowers have no reason to believe that the parties to the Government
Contracts will not fulfill their obligations thereunder in all material
respects.

     5-29. Capital Expenditures. None of the Borrowers will, nor will any
Borrower permit any Subsidiary to, make any Capital Expenditures during any
fiscal year of the Lead Borrower unless the aggregate amount of all Capital

or $6,500,000 in any fiscal year thereafter.

are hereby expressly waived by each Borrower, and/or (ii) terminate the
Commitment of the Lenders, whereupon the Total Commitment of the Lenders (and
the Commitment of each individual Lender) to make Loans and issue L/Cs hereunder
shall forthwith terminate without any other notice of any kind; and with respect
to any event described in Section 8-7 above, the Commitments shall automatically
terminate and the principal of the Liabilities then outstanding, together with
accrued interest thereon and all other amounts then due hereunder, shall
automatically become due and payable, without presentment, demand, protest or
any other notice of any kind, all of which are hereby expressly waived by each
of the Borrowers, anything contained herein or in any other Loan Document to the
contrary notwithstanding. Without limiting any provision of this Agreement or of
any Loan Document, an Event of Default under this Agreement shall also
constitute an event of default under each of the Loan Documents.

     9-2. Rights and Remedies.

     (a) The rights, remedies, powers, privileges, and discretions of the
Administrative Agent hereunder (herein, the "ADMINISTRATIVE AGENT'S RIGHTS AND
REMEDIES") shall be cumulative and not exclusive of any rights or remedies which
it would otherwise have. No delay or omission by the Administrative Agent in
exercising or enforcing any of the Agent's Rights and Remedies shall operate as,
or constitute, a waiver thereof. No waiver by the Administrative Agent of any
Event of Default or of any default under any other agreement shall operate as a
waiver of any other default hereunder or under any other agreement. No single or
partial exercise of any of the Administrative Agent's Rights or Remedies, and no
express or implied agreement or transaction of whatever nature entered into
between the Administrative Agent and any Person, at any time, shall preclude the
other or further exercise of the Administrative Agent's Rights and Remedies. No
waiver by the Administrative Agent of any of the Administrative

                                      -54-

<PAGE>

Agent's Rights and Remedies on any one occasion shall be deemed a waiver on any
subsequent occasion, nor shall it be deemed a continuing waiver. All of the
Administrative Agent's Rights and Remedies and all of the Administrative Agent's
rights, remedies, powers, privileges, and discretions under any other agreement
or transaction are cumulative, and not alternative or exclusive, and may be
exercised by the Administrative Agent at such time or times and in such order of
preference as the Administrative Agent in its sole discretion may determine. The
Administrative Agent's Rights and Remedies may be exercised without resort or
regard to any other source of satisfaction of the Liabilities.

     (b) Without limiting the provisions of subsection (a) above, if and only if
an Event of Default has occurred and be continuing, then on the Business Day
that the Lead Borrower receives notice from the Administrative Agent demanding
the deposit of cash collateral pursuant to this paragraph, the Borrowers shall
deposit in a cash collateral account, under the sole dominion and control of the
Administrative Agent, an amount in cash equal to 103% of the stated amount of
the outstanding L/Cs as of such date plus any accrued and unpaid interest
thereon. Each such deposit shall be held by the Administrative Agent as
collateral for the payment and performance of the Liabilities of the Borrowers.
The Administrative Agent shall have exclusive dominion and control, including
the exclusive right of withdrawal, over such cash collateral account. Other than
any interest earned on the investment of such deposits, which investments shall
be made at the option and sole discretion of the Administrative Agent at the
request of the Lead Borrower and at the Borrowers' risk and expense, such
deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account. Moneys in such cash collateral
account shall be applied by the Administrative Agent to reimburse the
Administrative Agent for payments on account of drawings under L/Cs for which it
has not been reimbursed and, to the extent not so applied, shall be held first
for the satisfaction of the reimbursement obligations of the Borrowers for the
outstanding L/Cs at such time and thereafter be applied to satisfy other
Liabilities of the Borrowers under this Agreement.

     9-3. Distribution of Funds. In the event that, following the occurrence and
during the continuance of any Event of Default, the Administrative Agent or any
Lender, as the case may be, receives any monies in connection with the
enforcement of any of the Loan Documents, such monies shall be distributed for
application as follows:

     (a) First, to the payment of, or (as the case may be) the reimbursement of
the Administrative Agent for or in respect of, all reasonable costs, expenses,
disbursements and losses which shall have been incurred or sustained by the
Administrative Agent in connection with the collection of such monies by the
Administrative Agent, for the exercise, protection or enforcement by the
Administrative Agent of all or any of the rights, remedies, powers and
privileges of the Administrative Agent under this Agreement or any of the other
Loan Documents or in support of any provision of adequate indemnity to the
Administrative Agent against any taxes or liens which by law shall have, or may
have, priority over the rights of the Administrative Agent to such monies;

     (b) Second, pro rata to each of the Lenders to all other Liabilities;

                                      -55-

<PAGE>

     (c) Third, upon payment and satisfaction in full or other provisions for
payment in full satisfactory to the Lenders and the Administrative Agent of all
of the Liabilities, to the payment of any obligations required to be paid
pursuant to Section 9-615(a)(3) of the UCC, in effect from time to time; and

     (d) Fourth, the excess, if any, shall be returned to the Borrowers or to
such other Persons as are entitled thereto.

ARTICLE 11 - TERM OF AGREEMENT.

     11-1. Termination of Revolving Credit. The Revolving Credit shall be
terminated upon the Termination Date.

     11-2. Effect of Termination. Upon the Termination Date, the Borrowers shall
pay the Administrative Agent, for the benefit of the Lenders, the then principal
balance of the Loans, together with any and all accrued and unpaid interest
thereon (whether or not then due). Following such payment, all provisions of
this Agreement, other than those contained in Article 3, which place an
obligation on the Lenders to make any loans or advances or to provide financial
accommodations under the Revolving Credit or to issue L/Cs shall remain in full
force and effect until all Liabilities shall have been paid in full.

ARTICLE 12 - GENERAL.

     12-1. Successors and Assigns. This Agreement shall be binding upon the
Borrowers and the Borrowers' representatives, successors, and assigns and shall
inure to the benefit of the Administrative Agent, the Lenders and their
respective successors and assigns; provided, however, no trustee or other
fiduciary appointed with respect to the Borrowers shall have any rights
hereunder. In the event that any Lender assigns or transfers its rights under

and duties of such Lender hereunder and such Lender shall thereupon be
discharged and relieved from its duties and obligations hereunder.

     12-2. Severability. Any determination that any provision of this Agreement

such provision in any other instance, or the validity, legality, or
enforceability of any other provision of this Agreement.

     12-3. Amendments; Course of Dealing.

     (a) This Agreement and the other Loan Documents incorporate all discussions
and negotiations among the Borrowers, Agents and the Lenders, either express or
implied, concerning the matters included herein and in such other instruments,
any custom, usage, or course of dealings to the contrary notwithstanding. No
such discussions, negotiations, custom, usage, or course of dealings shall
limit, modify, or otherwise affect the provisions thereof. No failure by the
Administrative Agent to give notice to any Borrower of such Borrower's having
failed to observe and comply with any warranty or covenant included in any Loan
Document shall constitute a waiver of such warranty or covenant or the amendment
of the subject Loan Document. No change made by the Administrative Agent in the
manner by which Availability is determined shall obligate the Administrative
Agent to continue to determine Availability in that manner. The Borrowers may
undertake any action otherwise prohibited hereby, and may omit to take any
action otherwise required hereby, upon and with the express prior written
consent of the Required Lenders or such other Persons' consent as may be
required by Section 13-17. No consent, modification, amendment, or waiver of any
provision of any Loan Document shall be effective unless executed in writing by
or on behalf of the party to be charged with such modification, amendment, or
waiver (and if such party is a Lender, then by a duly authorized officer
thereof). Any modification, amendment, or waiver provided by the Required
Lenders shall be in reliance upon all representations and warranties theretofore
made to the Lenders by or on behalf of the Borrowers (and any guarantor,
endorser, or surety of the Liabilities) and consequently may be rescinded by the
Lenders in the event that any of such representations or warranties was not true
and complete in all material respects when given.

     12-4. Costs and Expenses. The Borrowers shall pay on demand all Costs of
Collection and all reasonable expenses of the Administrative Agent in connection
with the preparation, execution, and delivery of this Agreement and of any other
Loan Documents, whether now existing or hereafter arising, including, without
limitation, all appraisal, inspection and other reports conducted in connection
with the underwriting of this Agreement and the loans contemplated hereby, and
all other reasonable expenses which may be incurred by the Administrative Agent
in preparing or amending this Agreement and all other agreements, instruments,
and documents related thereto, or otherwise incurred with respect to the
Liabilities.

     12-5. Copies and Facsimiles. This Agreement and all documents which relate
thereto, which have been or may be hereinafter furnished to the Lenders may be
reproduced by the Lenders by any photographic, microfilm, xerographic, digital
imaging, or other process, and the Lenders may destroy any document so
reproduced. Any such reproduction shall be admissible in evidence as the
original itself in any judicial or administrative proceeding (whether or not the
original is in existence and whether or not such reproduction was made in the
regular course of business). Any facsimile which bears proof of transmission
shall be binding on the party which or on whose behalf such transmission was
initiated and likewise shall be so admissible in evidence as if the original of
such facsimile had been delivered to the party which or on whose behalf such
transmission was received.

Borrower's address for notices as specified herein, such service to become
effective five (5) Business Days after such mailing.

     (c) Each Borrower WAIVES, at the option of the Administrative Agent, any
objection based on forum non conveniens and any objection to venue of any action
or proceeding instituted under any of the Loan Documents and consents to the
granting of such legal or equitable remedy as is deemed appropriate by the
Court.

     (d) Nothing herein shall affect the right of the Administrative Agent to
bring legal actions or proceedings in any other competent jurisdiction.

     (e) Each Borrower agrees that any action commenced by any Borrower
asserting any claim or counterclaim arising under or in connection with this
Agreement or any other Loan Document shall be brought in the Superior Court of

     12-8. Indemnification. Each Borrower shall jointly and severally indemnify,
defend, and hold the Administrative Agent and each Lender and any employee,
officer, or agent of the Administrative Agent and any Lender (each, an
"INDEMNIFIED PERSON") harmless of and from any claim brought or threatened
against any Indemnified Person by any Borrower, any guarantor or endorser of the
Liabilities, or any other Person (as well as from attorneys' reasonable fees and
expenses in connection therewith) on account of the Administrative Agent's and
such Lender's relationship with the Borrowers or any other guarantor or endorser
of the Liabilities (each of which may be defended, compromised, settled, or
pursued by the Indemnified Person with counsel of the Administrative Agent'
selection, but at the expense of the Borrowers) other than any claim as to which
a final determination is made in a judicial proceeding (in which the

                                      -59-

<PAGE>

Administrative Agent and any other Indemnified Person has had an opportunity to
be heard), which determination includes a specific finding that the Indemnified
Person seeking indemnification had acted in a grossly negligent manner, with
willful misconduct or in actual bad faith. This indemnification shall survive
payment of the Liabilities and/or any termination, release, or discharge
executed by the Administrative Agent in favor of the Borrowers.

<PAGE>

     (b) The Loan Documents shall be construed and interpreted in a harmonious
manner and in keeping the intentions set forth in Section 12-10 hereof;

property of the Borrowers in the possession of such Lender may be applied to or
set off against the payment of Liabilities and any and all other liabilities,

of distribution, pro tanto assignment of claims, subrogation or otherwise as

such maximum rate shall be held, to the extent of such excess, as collateral for
the Liabilities.

     12-13. Waivers.

     (a) Each Borrower (and all guarantors, endorsers, and sureties of the
Liabilities) make each of the waivers included in subsection (b), below,

     BETWEEN ANY BORROWER OR ANY OTHER PERSON, ANY AGENT AND/OR ANY LENDER (AND
     EACH AGENT AND EACH LENDER LIKEWISE WAIVES THE RIGHT TO A JURY IN ANY TRIAL
     OF ANY SUCH CASE OR CONTROVERSY).

subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in ARTICLE 4, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof that, when taken together, bear the

ARTICLE 13 - THE AGENT.

     13-1. Authorization; Non-Reliance by Lenders; Reliance by Administrative
Agent; Dispute Resolution.

     (a) Each Lender appoints and designates Brown Brothers Harriman & Co., as
the "Administrative Agent" hereunder and under the Loan Documents. Each Lender
hereby authorizes the Administrative Agent (i) to execute those Loan Documents
and all other instruments relating thereto to which the Administrative Agent is
a party, and (ii) to take such action on behalf of each of the Lenders and to
exercise all such powers as are hereunder and under any of the other Loan
Documents and any related documents delegated to the Administrative Agent,
together with such powers as are reasonably incident thereto, provided that no
duties or responsibilities not expressly assumed herein or therein shall be
implied to have been assumed by the Administrative Agent. The relationship
between the Administrative Agent and the Lenders is and shall be that of agent
and principal only, and nothing contained in this Agreement or any of the other
Loan Documents shall be construed to constitute Administrative Agent as a
trustee or fiduciary for any Lender. The Administrative Agent shall not have any
duties or responsibilities to, or any fiduciary relationship with, any Lender
except for those expressly set forth in this Agreement. The Borrowers
acknowledge that in certain instances any action to be taken by the
Administrative Agent may only be taken upon approval of the Required Lenders or
all the Lenders.

     (b) Each Lender represents to all other Lenders and to the Administrative
Agent that such Lender:

          (i) Independently and without reliance on any representation or act by

applicable consent required by this Agreement. Instructions given with the
requisite consent shall be binding on all Lenders.

     (h) Any dispute among the Lenders and/or the Administrative Agent
concerning the interpretation, administration, or enforcement of the financing

     13-5. Funding Procedures; Payments.

     (a) The Administrative Agent shall advise each Lender, no later than 2:00PM
(Boston Time) (A) on a date on which any Revolving Credit Loan is to be made to
the Lead Borrower on that date, and (B) on the date of any request for the
making, Conversion or continuation of a LIBOR Loan. Such advice, in each
instance, may be by telephone or facsimile transmission, provided that if such
advice is by telephone, it shall be confirmed in writing. Advice of a Revolving
Credit Loan shall include the amount of and interest rate applicable to the
subject Revolving Credit Loan. Subject to that Lender's Commitment of the
Revolving Credit, each Lender, by not later than the end of business on the day
on which the subject Revolving Credit Loan is to be made, shall transfer that
Revolving Credit Lender's Revolving Credit Commitment Percentage of the subject
Revolving Credit Loan to the Administrative Agent.

     (b) Each Revolving Credit Lender shall make available to the Administrative
Agent, as applicable, as provided herein, that Lender's Revolving Credit
Commitment Percentage of the following:

                                      -65-

<PAGE>

          (i) Each Revolving Credit Loan, up to the maximum amount of that
     Revolving Credit Lender's Revolving Credit Commitment of the Revolving
     Credit Loans.

          (ii) Up to the maximum amount of that Lender's Revolving Credit
     Commitment of each drawing on a L/C (to the extent that such L/C Drawing is
     not "covered" by a Revolving Credit Loan as provided herein).

     (c) In all circumstances, the Administrative Agent may:

          (i) Assume that each Lender, subject to Section 13-5(a), timely shall
     make available to the Administrative Agent that Lender's Revolving Credit
     Commitment Percentage of each Revolving Credit Loan, notice of which is
     provided pursuant to Section (a).

          (ii) In reliance upon such assumption, make available the
     corresponding amount to the applicable Borrowers.

          (iii) Assume that each Lender timely shall pay, and shall make
     available, to the Administrative Agent all other amounts which that Lender
     is obligated to so pay and/or make available hereunder or under any of the
     Loan Documents.

     (d) (i) A payment by the Borrowers to the Administrative Agent hereunder or
any of the other Loan Documents for the account of any Lender shall constitute a
payment to such Lender. The Administrative Agent agrees promptly to distribute
to each Lender such Lender's Commitment Percentage of payments received by the
Administrative Agent for the account of the Lenders except as otherwise
expressly provided herein or in any of the other Loan Documents;

          (ii) the amount of each Lender's Commitment Percentage of outstanding
     Revolving Credit Loans shall be computed weekly (or more frequently in the
     Administrative Agent's discretion) and shall be adjusted upward or downward
     based on all Revolving Credit Loans and repayments of Revolving Credit
     Loans received by the Administrative Agent as of 3:00 p.m., Boston time, on
     the first Business Day following the end of the period specified by the
     Administrative Agent (such date, the "SETTLEMENT DATE");

          (iii) the Administrative Agent shall deliver to each of the Lenders
     promptly after the Settlement Date a summary statement of the amount of
     outstanding Revolving Credit Loans for the period and the amount of
     repayments received for the period. As reflected on the summary statement:
     (x) the Administrative Agent shall transfer to each Lender its applicable
     Commitment Percentage of repayments, and (y) each Lender shall transfer to
     the Administrative Agent (as provided below), or the Administrative Agent
     shall transfer to each Lender, such amounts as are necessary to insure
     that, after giving effect to all such transfers, the amount of Revolving
     Credit Loans made by each Lender with respect to Revolving Credit Loans
     shall be equal to such Lender's applicable Commitment Percentage of
     Revolving Loans outstanding as of such Settlement Date. If

                                      -66-

<PAGE>

     the summary statement requires transfers to be made to the Administrative
     Agent by the Lenders and is received prior to 12:00 Noon, Boston time, on a
     Business Day, such transfers shall be made in immediately available funds
     no later than 11:00 a.m., Boston time, that day; and, if received after
     11:00 a.m., Boston time, then no later than 3:00 p.m., Boston time, on the
     next Business Day. The obligation of each Lender to transfer such funds is
     irrevocable, unconditional and without recourse to or warranty by the
     Administrative Agent. If and to the extent any Lender shall not have so
     made its transfer to the Administrative Agent, such Lender agrees to pay to
     the Administrative Agent, forthwith on demand such amount, together with
     interest thereon, for each day from such date until the date such amount is
     paid to the Administrative Agent at the Federal Funds Effective Rate.

     (e) The Borrowers acknowledge that each Lender's responsibilities hereunder
are several and that each Lender shall only be responsible to fund up to each
Lender's Commitment Percentage. The Borrowers agree to release and hold harmless
any nondelinquent Lenders from any claims, damages or costs arising on account
of any failure of a Delinquent Lender to comply with the requirements of this
Agreement.

     (f) If in the opinion of the Administrative Agent the distribution of any
amount received by it in such capacity hereunder, under the Notes or under any
of the other Loan Documents might involve it in liability, it may refrain from
making distribution until its right to make distribution shall have been
adjudicated by a court of competent jurisdiction (provided that such action by
the Administrative Agent shall not create an independent default by the
Borrowers). If a court of competent jurisdiction shall adjudge that any amount
received and distributed by the Administrative Agent is to be repaid, each
Person to whom any such distribution shall have been made shall either repay to
the Administrative Agent its proportionate share of the amount so adjudged to be
repaid or shall pay over the same in such manner and to such Persons as shall be
determined by such court.

     13-6. Holders of Notes. The Administrative Agent may deem and treat the
payee of any Note as the absolute owner or purchaser thereof for all purposes
hereof until it shall have been furnished in writing with a different name by
such payee or by a subsequent holder, assignee or transferee.

     13-7. Indemnity. The Lenders ratably agree hereby to indemnify and hold
harmless the Administrative Agent from and against any and all claims, actions
and suits (whether groundless or otherwise), losses, damages, costs, out of
pocket expenses (including any expenses for which the Administrative Agent has
not been reimbursed by the Borrowers as required by Section 12-4), and
liabilities of every nature and character arising out of or related to this
Agreement, the Notes, or any of the other Loan Documents or the transactions
contemplated or evidenced hereby or thereby, or the Administrative Agent's
actions taken hereunder or thereunder, except to the extent that any of the same
shall be directly caused by the Administrative Agents' willful misconduct or
gross negligence.

     13-8. Administrative Agent as Lender; Limitation on other Agents'
Liability. In its individual capacity, Brown Brothers Harriman & Co. shall have
the same obligations and the

                                      -67-

<PAGE>

same rights, powers and privileges in respect to its Commitments and the Loans
made by it, and as the holder of any of the Notes as it would have were it not
also the Administrative Agent. None of the Documentation Agent or the
Syndication Agent, in such capacities, shall have any right, power, obligation,
liability, responsibility or duty under this Agreement or any other Loan
Document.

     13-9. Resignation. The Administrative Agent may resign at any time by
giving sixty (60) days' prior written notice thereof to the Lenders and the
Borrowers. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor to Administrative Agent. Unless an Event of Default shall
have occurred and be continuing, such successor Administrative Agent shall be
reasonably acceptable to the Borrowers in their reasonable discretion. If no
successor Administrative Agent shall have been so appointed by the Required
Lenders and shall have accepted such appointment within thirty (30) days after
the retiring Administrative Agent's giving of notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, after consultation
with the Lenders, appoint a successor Administrative Agent, which shall be a
Lender or which meets the requirements of subjection (a) of the definition of an
Eligible Assignee, and unless an Event of Default shall have occurred and be
continuing, such successor Administrative Agent being reasonably acceptable to
the Borrowers in its reasonable discretion. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative
Agent's resignation, the provisions of this Agreement and the other Loan
Documents shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Administrative Agent.
In addition, if at any time Administrative Agent shall no longer act as a Lender
hereunder (subject to the provisions of Section 13-13 below), unless same
results from a merger or other consolidation of the Administrative Agent with a
Lender, the Required Lenders shall have the right to appoint a successor
Administrative Agent subject to the provisions of this Section 13-9.

     13-10. Notification of Suspension Events and Events of Default;
Distributions of Notices and Documents by Administrative Agent. (a) Each Lender
hereby agrees that, upon learning of the existence of a Suspension Event or an
Event of Default, it shall promptly notify the Administrative Agent thereof. The
Administrative Agent hereby agrees that upon receipt of any notice under this
Section 13-10 it shall promptly notify in writing the other Lenders of the
existence of such Suspension Event or Event of Default.

     (b) The Administrative Agent, to the extent that the Administrative Agent
has not done so, will forward to each Lender, promptly after the Administrative
Agent's receipt thereof, a copy of each notice or other document furnished to
the Administrative Agent pursuant to this Agreement, including quarterly and
annual financial statements received from the Borrowers pursuant to ARTICLE 7 of
this Agreement, other than any of the following:

          (i) Routine communications associated with requests for Revolving
     Credit Loans and/or the issuance of L/C's.

                                      -68-
<PAGE>

          (ii) Routine or nonmaterial communications.

          (iii) Any notice or document required by any of the Loan Documents to
     be furnished to the Lenders by the Borrowers.

          (iv) Any notice or document of which the Administrative Agent has
     knowledge that such notice or document had been forwarded to the Lenders
     other than by the Administrative Agent.

     13-11. Duties in the Case of Enforcement. In case that one or more Events
of Default have occurred and shall be continuing, and whether or not
acceleration of the Liabilities shall have occurred, the Administrative Agent
shall, if (a) so requested by the Required Lenders and (b) the Required Lenders
have provided to the Administrative Agent such additional indemnities and
assurances against expenses and liabilities as the Administrative Agent may
reasonably request, proceed to enforce the provisions of the Loan Documents and
exercise all or any such legal and equitable and other rights or remedies as it
may have in respect of the Loan Documents. The Required Lenders may direct the
Administrative Agent in writing as to the method and the extent of any such
rights or remedies, the Lenders hereby agreeing to indemnify and hold the
Administrative Agent harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions, provided that the
Administrative Agent need not comply with any such direction to the extent that
the Administrative Agent reasonably believes its compliance with such direction
to be unlawful or, upon the advice of counsel, would be found to be commercially
unreasonable in any applicable jurisdiction. The Administrative Agent may, in
its discretion but without obligation, in the absence of direction from the
Required Lenders, take such interim actions as they believe necessary to
preserve the rights of the Lenders hereunder, including but not limited to
petitioning a court for injunctive relief or appointment of a receiver. Each of
the Lenders acknowledges and agrees that no individual Lender may separately
enforce or exercise any of the provisions of any of the Loan Documents,
including without limitation the Notes, other than through the Administrative
Agent.

     13-12. Delinquent Lender. If for any reason any Lender shall fail or refuse
to abide by its obligations under the Agreement, including without limitation
its obligation to make available to the Administrative Agent its pro rata share
of any Loan, expenses or setoff (a "DELINQUENT LENDER") and such failure is not
cured within ten (10) days of receipt from the Administrative Agent of written
notice thereof, then, in addition to the rights and remedies that may be
available to Administrative Agent, other Lenders, the Borrowers or any other
party at law or in equity, and not at limitation thereof, (i) such Delinquent
Lender's right to participate in the administration of, or decision-making
rights related to, any Loan, this Agreement or the other Loan Documents shall be
suspended during the pendency of such failure or refusal, and (ii) a Delinquent
Lender shall be deemed to have assigned any and all payments due to it from the
Borrowers, whether on account of the outstanding Loans, interest, fees or
otherwise, to the remaining non-delinquent Lenders for application to, and
reduction of, their proportionate shares of the outstanding Loans until, as a
result of application of such assigned payments the Lenders' respective pro rata
shares of the outstanding Loans shall have returned to those in effect
immediately prior to such delinquency and without giving effect to the
nonpayment causing such delinquency. The Delinquent Lender's decision-making and
participation rights to payments as set forth in clauses

                                      -69-

<PAGE>

(i) and (ii) hereinabove shall be restored only upon the payment by the
Delinquent Lender of its pro rata share of the Loans or expenses as to which it
is delinquent, together with interest thereon at the Default Rate from the date
when originally due until the date upon which any such amounts are actually
paid.

     The non-delinquent Lenders shall also have the right, but not the
obligation, in their respective, sole and absolute discretion, to acquire for no
cash consideration, (pro rata, based on the respective Commitments of those
Lenders electing to exercise such right) the Delinquent Lender's Commitment to
fund any future Loan (the "FUTURE COMMITMENT"). Upon any such purchase of the
pro rata share of any Delinquent Lender's Future Commitment, the Delinquent
Lender's share in any future Loans and its rights under the Loan Documents with
respect thereto shall terminate on the date of purchase, and the Delinquent
Lender shall promptly execute all documents reasonably requested to surrender
and transfer such interest, including, if so requested, an Assignment and
Acceptance. Each Delinquent Lender shall indemnify Administrative Agent and each
non-delinquent Lender from and against any and all loss, damage or expenses,
including but not limited to reasonable attorneys' fees and funds advanced by
Administrative Agent or by any non-delinquent Lender, on account of an
Delinquent Lender's failure to timely fund its pro rata share of a Loan or to
otherwise perform its obligations under the Loan Documents.

     13-13. Assignment and Participation.

     (a) Conditions to Assignment by Lenders. Except as provided herein, each
Lender may assign to one or more Eligible Assignees (or to any third party after
the occurrence of an Event of Default and while same is continuing) all or a
portion of its interests, rights and obligations under this Agreement (including
all or a portion of its Commitment Percentage and Commitment and the same
portion of the Loans at the time owing to it and the Notes held by it), upon
satisfaction of the following conditions: (a) each of the Administrative Agent

constant, and not a varying, percentage of all the assigning Lender's rights and
obligations under this Agreement, (c) prior to the occurrence of an Event of

such assignment and upon payment to the Administrative Agent of the registration
fee referred to in Section 13-13(c), be released from its obligations under this
Agreement.

a new Note to the order of such assignee in an amount equal to the amount
assumed by such assignee pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained some portion of its obligations hereunder, a new

assigning Lender, and neither the Administrative Agent nor any other Lender
shall have any obligation, duty or liability to any such participant of any
other Lender.

     13-14. Pledge to Federal Reserve. Any Lender may at any time pledge all or
any portion of its rights under the Loan Documents including any portion of the
Notes to any of the twelve (12) Federal Reserve Banks organized under Section 4

Lenders or all of the Lenders, as the case may be, in accordance with the terms

<PAGE>

Lenders, as the case may be, prior to undertaking a particular action or course
of conduct, the Administrative Agent in each such case shall provide each Lender
with written notice of any such request for amendment, waiver or consent or any
other requested or proposed action or course of conduct, accompanied by such

     13-16. Treatment of Confidential Information. Each of the Lenders and the
Agents agrees to maintain the confidentiality of the Confidential Information
(as defined below), except that Confidential Information may be disclosed:

     (a) to its officers, directors, employees and representatives and only on a
"need to know" basis (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such
Confidential Information and instructed to keep such Confidential Information
confidential);

     (b) to the extent requested by any regulatory authority purporting to have
jurisdiction over it;

     (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process;

     (d) in connection with the exercise of any remedies hereunder or under any
other Loan Document or any action or proceeding relating to this Agreement or
any other Loan Document or the enforcement of rights hereunder or thereunder;

     (e) subject to an agreement containing provisions substantially the same as
those of this Section, to (i) any assignee of or participant in, or any
prospective assignee of or participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to the any Borrower and
its obligations;

     (f) with the prior written consent of the Lead Borrower; or

     (g) to the extent such Information (i) becomes publicly available other
than as a result of a breach of this Section or (ii) becomes available to the
Administrative Agent or any Lender on a non-confidential basis from a source
other than the Borrowers.

     For purposes of this Section, "Confidential Information" means all
information received from any of Borrowers or any subsidiary relating to any
Borrower or any Subsidiary or any of their respective businesses, other than any
such information that is available to Administrative Agent or any Lender on a
non-confidential basis prior to disclosure by any Borrower or any Subsidiary,
provided, however, that, in the case of Confidential Information received from
any Borrower or any Subsidiary after the date hereof, such Confidential
Information is clearly identified at the time of delivery as confidential. Any
Person required to maintain the confidentiality of any Confidential Information
as provided in this Section shall be considered to

                                      -73-

<PAGE>

have complied with its obligation to do so if such Person has exercised the same
degree of care to maintain the confidentiality of such Confidential Information
as such Person would accord to its own confidential information but no less than
a reasonable standard of care.

     13-17. Consents, Amendments, Waivers, etc..

     (a) Except as otherwise expressly set forth in any particular provision of
this Agreement, any consent or approval required or permitted by this Agreement
to be given by the Administrative Agent or the Lenders may be given, and any
term of this Agreement or of any other instrument related hereto or mentioned
herein may be amended, and the performance or observance by the Borrowers of any
terms of this Agreement or such other instrument or the continuance of any Event
of Default may be waived (either generally or in a particular instance and
either retroactively or prospectively) by the Administrative Agent or the
Required Lenders, as applicable, in their discretion. Each such consent,
amendment or waiver shall be in writing. No waiver shall extend to or affect any
obligation not expressly waived or impair any right consequent thereon. No
course of dealing or delay or omission on the part of the Administrative Agent
or any Lender in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto. No Loan made by the Administrative Agent
hereunder during the continuance of any Suspension Event or Event of Default
shall constitute a waiver thereof. No notice to or demand upon the Borrowers
shall entitle the Borrower to other or further notice or demand in similar or
other circumstances.

     (b) Notwithstanding anything to the contrary contained in this Agreement,
any provisions of this Agreement pertaining to the administration of the Loans
by the Lenders may be amended by an instrument in writing signed by the
Administrative Agent and the Required Lenders with no additional consent
required from the Borrowers.

     (c) Notwithstanding the foregoing, the unanimous written approval of all
the Lenders (other than a Delinquent Lender) shall be required with respect to
any proposed amendment, waiver, discharge, termination, or consent which:

          (i) has the effect of, except as provided herein, (a) extending any
     Maturity Date or the date of any amortization payment of any Note, (b)
     reducing the interest rate, extending the time of payment, or changing the
     manner of calculation, of interest or fees thereon, (c) increasing or
     reducing the principal amount thereof, or (d) otherwise postponing or
     forgiving any Indebtedness thereunder;

          (ii) changes the definition of Required Lenders or reduces the
     percentages specified in the definition of Required Lenders;

          (iii) except as otherwise provided in this Agreement, change the
     amount of any Lender's Commitment or Commitment Percentage;

          (iv) releases or waives any guaranty of the Liabilities or
     indemnifications provided in the Loan Documents;

                                      -74-

<PAGE>

          (v) changes to the definition of Consolidated Operating Cash Flow,
     Consolidated Total Net Worth, Consolidated Total Funded Indebtedness, EBIT,
     EBITDA, Net Income, Permitted Acquisition or Total Debt Service;

          (vi) amends, modifies or waives any provisions of this paragraph; or

          (vii) amends, modifies or waives any term or condition of Sections
     5-6, 5-19(o), 5-21(c),5-22, 5-29, 7-7, 7-8, 7-9 or 7-10.

     (d) Without the consent of the subject Agent, no such action shall amend,
modify or waive any provision of any Loan Document which relates to the rights
or obligations of the specific Agent.

     13-18. U.S. Patriot Act. Each Lender hereby notifies the Borrowers that
pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56
(signed into law October 26, 2001)) (the "ACT"), it is required to obtain,
verify and record information that identifies the Borrowers, which information
includes the name and address of each Borrower and other information that will
allow such Lender to identify such Borrower in accordance with the Act.

     13-19. Foreign Asset Control Regulations. Neither of the advance of the
Revolving Credit Loans nor the use of the proceeds of any thereof (or any other
Loan) will violate the Trading With the Enemy Act (50 U.S.C. Section 1 et seq.,
as amended) (the "Trading With the Enemy Act") or any of the foreign assets
control regulations of the United States Treasury Department (31 CFR, Subtitle
B, Chapter V, as amended) (the "Foreign Assets Control Regulations") or any
enabling legislation or executive order relating thereto (which for the
avoidance of doubt shall include, but shall not be limited to (a) Executive
Order 13224 of September 21, 2001 Blocking Property and Prohibiting Transactions
With Persons Who Commit, Threaten to Commit, or Support Terrorism (66 Fed. Reg.
49079 (2001)) (the "Executive Order") and (b) the Uniting and Strengthening
America by Providing Appropriate Tools Required to Intercept and Obstruct
Terrorism Act of 2001 (Public Law 107-56)). Furthermore, none of the Borrowers
or their Affiliates (a) is or will become a "blocked person" as described in the
Executive Order, the Trading With the Enemy Act or the Foreign Assets Control
Regulations or (b) engages or will engage in any dealings or transactions, or be
otherwise associated, with any such "blocked person".

                            MASTER UNLIMITED GUARANTY

     MASTER UNLIMITED GUARANTY, ("Guaranty") dated as of September 29, 2006 by
each of DYNAMICS RESEARCH CORPORATION, a Massachusetts corporation, DRC
INTERNATIONAL CORPORATION, a Massachusetts corporation, and H.J. FORD
ASSOCIATES, INC., a Delaware corporation (hereinafter, singly a "Guarantor" and
collectively, the "Guarantors"), in favor of BROWN BROTHERS HARRIMAN & CO., a
New York general partnership with offices at 40 Water Street, Boston,
Massachusetts, for itself and as Administrative Agent (the "Agent") for each of
the Lenders (defined below) which are and which may become parties to the Loan
Agreement (defined below). All capitalized terms used herein, and not otherwise
defined herein, shall have the meanings set forth in the Loan Agreement. In
consideration of the Agent's and the Lenders' giving, in their discretion,
credit or banking facilities or accommodations to each of those persons
described on Exhibit A annexed hereto and incorporated herein by reference (each
such person, together with its successors, individually a "Customer" and
collectively, the "Customers"), each Guarantor jointly and severally agrees as
follows:

1.   GUARANTY OF PAYMENT AND PERFORMANCE. Each Guarantor, jointly and severally
     hereby guarantees to the Agent and each Lender the full and punctual
     payment when due (whether at maturity, by acceleration or otherwise), and
     the performance, of all Liabilities of any Customer to the Agent or to any
     Lender in connection with that certain Third Amended and Restated Loan
     Agreement dated as of even date herewith (as same may be amended, modified
     or replaced, the "Loan Agreement"), made by and among the Customers, the
     Agent, TD Banknorth, N.A., as Documentation Agent and Bank of America,
     N.A., as Syndication Agent, and each of Brown Brothers Harriman & Co., TD
     Banknorth, N.A. and Bank of America, N.A., as lenders, and such other
     lenders which may hereafter become parties to the Loan Agreement (each a
     "Lender" and collectively, the "Lenders"). This Guaranty is an absolute,
     unconditional and continuing guaranty of the full and punctual payment and
     performance of the Liabilities and not of their collectibility only and is
     in no way conditioned upon any requirement that the Agent first attempt to
     collect any of the Liabilities from any Customer or resort to any security
     or other means of obtaining their payment. Upon the occurrence and
     continuance of any Event of Default, the obligations of the Guarantor
     hereunder shall become immediately due and payable to the Agent and the
     Lenders, without demand or notice of any nature, all of which are expressly
     waived by each Guarantor. Payments by any Guarantor hereunder may be
     required by the Agent on any number of occasions.

2.   GUARANTORS' AGREEMENT TO PAY. Each Guarantor further agrees, as the
     principal obligor and not as a guarantor only, to pay to the Agent for the
     ratable benefit of the Lenders, on demand, all costs and expenses
     (including court costs and legal expenses) incurred or expended by the
     Agent in connection with the Liabilities, this Guaranty and

                                      -1-

<PAGE>

     the enforcement thereof, together with interest on amounts recoverable
     under this Guaranty from the time such amounts become due until payment, at
     the rate per annum equal to the default rate set forth in the Loan
     Agreement applicable to the Liabilities after the occurrence and
     continuance of any Event of Default; provided that if such interest exceeds
     the maximum amount permitted to be paid under applicable law, then such
     interest shall be reduced to such maximum permitted amount.

3.   UNLIMITED GUARANTY. The liability of each Guarantor hereunder shall be
     unlimited.

4.   WAIVERS BY GUARANTORS; AGENT'S FREEDOM TO ACT. Each Guarantor agrees that
     the Liabilities 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 Agent with respect thereto. Each Guarantor waives
     presentment, demand, protest, notice of acceptance, notice of Liabilities
     incurred and all other notices of any kind, all defenses which 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 Customers, and all suretyship defenses generally. Without
     limiting the generality of the foregoing, each Guarantor agrees to the
     provisions of any instrument evidencing, securing or otherwise executed in
     connection with any Liability and agrees that the obligations of the
     Guarantors hereunder shall not be released or discharged, in whole or in
     part, or otherwise affected by (i) the failure of the Agent to assert any
     claim or demand or to enforce any right or remedy against any Customer;
     (ii) any extensions or renewals of any Liability; (iii) any rescissions,
     waivers, amendments or modifications of any of the terms or provisions of
     any agreement evidencing, securing or otherwise executed in connection with
     any Liability; (iv) the substitution or release of any entity primarily or
     secondarily liable for any Liability; (v) the adequacy of any rights the
     Agent or any Lender may have against any collateral or other means of
     obtaining repayment of the Liabilities; (vi) the impairment of any
     collateral securing the Liabilities, including without limitation the
     failure to perfect or preserve any rights the Agent 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
     which 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.

5.   UNENFORCEABILITY OF OBLIGATIONS AGAINST CUSTOMERS. If for any reason any
     Customer has no legal existence or is under no legal obligation to
     discharge any of the Liabilities, or if any of the Liabilities have become
     irrecoverable from any Customer by operation of law or for any other
     reason, this Guaranty shall nevertheless be binding on the Guarantors to
     the same extent as if the Guarantors at all times had been

                                      -2-

<PAGE>

     the principal obligor on all such Liabilities. In the event that
     acceleration of the time for payment of the Liabilities is stayed upon the
     insolvency, bankruptcy or reorganization of any Customer, or for any other
     reason, all such amounts otherwise subject to acceleration under the terms
     of any agreement evidencing, securing or otherwise executed in connection
     with any Liability shall be immediately due and payable by the Guarantors.

6.   SUBROGATION; SUBORDINATION. No Guarantor shall exercise any rights against
     any Customer or any other Guarantor arising as a result of payment by any
     Guarantor hereunder, by way of subrogation or otherwise, and will not prove
     any claim in competition with the Agent or any Lender or its affiliates in
     respect of any payment hereunder in bankruptcy or insolvency proceedings of
     any nature; no Guarantor will claim any set-off or counterclaim against any
     Customer in respect of any liability of the Guarantors to any Customer or
     any other Guarantor; and each Guarantor waives (until the Agent and each
     Lender is paid in full) any benefit of and any right to participate in any
     collateral which may be held by the Agent or any such affiliate. The
     payment of any amounts due with respect to any indebtedness of any Customer
     now or hereafter held by any Guarantor is hereby subordinated to the prior
     payment in full of the Liabilities, provided that so long as no default in
     the payment or performance of the Liabilities has occurred and is
     continuing, or no demand for payment of any of the Liabilities has been
     made that remains unsatisfied, the Customers may make and the Guarantors
     may receive payments or performance of any obligations to Guarantors which
     are permitted under the Loan Agreement. Each Guarantor agrees that after
     the occurrence and during the continuance of any default in the payment or
     performance of the Liabilities, no Guarantor will demand, sue for or
     otherwise attempt to collect any such indebtedness of any Customer to any
     Guarantor until the Liabilities shall have been paid in full. If,
     notwithstanding the foregoing sentence, any Guarantor shall collect,
     enforce or receive any amounts in respect of such indebtedness, such
     amounts shall be collected, enforced and received by such Guarantor as
     trustee for the Agent and be paid over to the Agent on account of the
     Liabilities without affecting in any manner the liability of such Guarantor
     under the other provisions of this Guaranty.

7.   SECURITY; SET-OFF. Regardless of the adequacy of any Collateral, during the
     continuance of any Event of Default, any deposits (general or specific,
     time or demand, provisional or final, regardless of currency, maturity, or
     the branch of where such deposits are held) or other sums credited by or
     due from any of the Lenders to any of the Guarantors and any securities or
     other property of the Guarantors in the possession of such Lender may be
     applied to or set off against the payment of Liabilities and any and all
     other liabilities, direct, or indirect, absolute or contingent, due or to
     become due, now existing or hereafter arising, of the Guarantors to the
     Lenders. Each Lender, by its acceptance of this Guaranty, hereby agrees
     that any payment received by Lender

                                      -3-

<PAGE>

     hereunder shall be subject to the terms and conditions set forth in Section
     12-11 of the Loan Agreement.

8.   FURTHER ASSURANCES. Each Guarantor also agrees to do all such things and
     execute all such documents, including financing statements, as the Agent
     may consider necessary or desirable to give full effect to this Guaranty
     and to perfect and preserve the rights and powers of the Agent hereunder.
     In addition, each Guarantor agrees that it will not incur any indebtedness,
     other than any indebtedness permitted under the Loan Agreement.

9.   TERMINATION; REINSTATEMENT. This Guaranty shall remain in full force and
     effect until the Agent is given written notice of the Guarantors' intention
     to discontinue this Guaranty, notwithstanding any intermediate or temporary
     payment or settlement of the whole or any part of the Liabilities. No such
     notice shall be effective unless received and acknowledged by an officer of
     the Agent at the address provided for in Article 10 of the Loan Agreement.
     No such notice shall affect any rights of the Agent or any Lender or of any
     affiliate hereunder including, without limitation, the rights set forth in
     Sections 4 and 6, with respect to Liabilities incurred prior to the receipt
     of such notice or Liabilities incurred pursuant to any contract or
     commitment in existence prior to such receipt, and all checks, drafts,
     notes, instruments (negotiable or otherwise) and writings made by or for
     the account of the Customers and drawn on the Agent or any Lender or any of
     their agents purporting to be dated on or before the date of receipt of
     such notice, although presented to and paid or accepted by the Agent or
     such Lender after that date, shall form part of the Liabilities. This
     Guaranty shall continue to be effective or be reinstated, notwithstanding
     any such notice, if at any time, any payment made or value received with
     respect to a Liability is rescinded or must otherwise be returned by the
     Agent or any Lender upon the insolvency, bankruptcy or reorganization of
     any Customer, or otherwise, all as though such payment had not been made or
     value received.

10.  SUCCESSORS AND ASSIGNS. This Guaranty shall be binding upon each Guarantor,
     its respective successors and assigns, and shall inure to the benefit of
     and be enforceable by the Agent and its successors, transferees and
     assigns. Without limiting the generality of the foregoing sentence, (i) the
     Agent or any Lender may, to the extent permitted by such agreement or note,
     assign or otherwise transfer any agreement or any note held by it
     evidencing, securing or otherwise executed in connection with the
     Liabilities, or sell participations in any interest therein, to any other
     person or entity, and (ii) such other person or entity 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 the Agent and such Lender herein.

                                      -4-

11.  AMENDMENTS AND WAIVERS. No amendment or waiver of any provision of this
     Guaranty nor consent to any departure by any Guarantor therefrom shall be
     effective unless the same shall be in writing and signed by the Agent
     pursuant to the provisions of the Loan Agreement. No failure on the part of
     the Agent 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 in accordance
     with the provisions of Article 10 of the Loan Agreement.

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. Each
     Guarantor agrees that any suit for the enforcement of this Guaranty may be
     brought in the courts of The Commonwealth of Massachusetts or any Federal
     Court sitting therein, consents to the non-exclusive jurisdiction of such
     court and agrees that a summons and complaint commencing an action or
     proceeding in any such court shall be properly served and shall confer
     personal jurisdiction if served personally or by certified mail to such
     Guarantor at its address provided in Article 10 of the Loan Agreement or as
     otherwise provided under the laws of The Commonwealth of Massachusetts.
     Each Guarantor 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.  MISCELLANEOUS. This Guaranty constitutes the entire agreement of the
     Guarantors with respect to the matters set forth herein. The rights and
     remedies herein provided are cumulative and not exclusive of any remedies
     provided by law or any other agreement, and this Guaranty shall be in
     addition to any other guaranty of the Liabilities. The invalidity or
     unenforceability of any one or more sections of this Guaranty shall not
     affect the validity or enforceability of its remaining provisions. Captions
     are for the ease of reference only and shall not affect the meaning of the
     relevant provisions. The meanings of all defined terms used in this
     Guaranty shall be equally applicable to the singular and plural forms of
     the terms defined.

15.  JURY WAIVER. THE AGENT (BY ITS ACCEPTANCE HEREOF) AND EACH GUARANTOR AGREE
     THAT NONE OF THEM, INCLUDING ANY ASSIGNEE OR SUCCESSOR SHALL SEEK A JURY
     TRIAL IN ANY LAWSUIT, PROCEEDING, COUNTERCLAIM, OR ANY OTHER LITIGATION
     PROCEDURE BASED UPON, OR ARISING OUT OF, THIS GUARANTY, ANY RELATED
     INSTRUMENTS, ANY

                                      -5-

<PAGE>

     COLLATERAL OR THE DEALINGS OR THE RELATIONSHIP BETWEEN OR AMONG ANY OF
     THEM. NEITHER THE AGENT NOR ANY GUARANTOR SHALL SEEK TO CONSOLIDATE ANY
     SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS
     NOT BEEN WAIVED. THE PROVISIONS OF THIS PARAGRAPH HAVE BEEN FULLY DISCUSSED
     BY THE AGENT AND THE GUARANTORS, AND THESE PROVISIONS SHALL BE SUBJECT TO
     NO EXCEPTIONS. NEITHER THE AGENT NOR ANY GUARANTOR HAS AGREED WITH OR
     REPRESENTED TO THE OTHER THAT THE PROVISIONS OF THIS PARAGRAPH WILL NOT BE
     FULLY ENFORCED IN ALL INSTANCES.

16.  AMENDED AND RESTATED GUARANTY. This Guaranty amends and restates any
     Guaranty executed and delivered previously by any Guarantor in connection
     with the Existing Loan Agreement.
