                2.4 From and after the date of this Fourth Amendment, all

maximum principal amount of the Revolving Credit Loan and Borrower agrees
thereto, Borrower shall immediately execute and deliver to Lender a further
Revolving Credit Note to evidence such increase;

                                  (2) Each advance on account of the Revolving

Credit Loans made by Lender to Borrower pursuant
to this Paragraph 3B shall be recorded in an account on the books of Lender

render and send to Borrower a monthly statement of Borrower's Account showing
the outstanding aggregate principal balance of the Revolving Credit Loan,
together with interest and other appropriate debits and credits as of the date
of the statement. The statement of Borrower's Account shall be considered
correct in all respects, absent manifest error, and accepted by and be
conclusively binding upon Borrower unless Borrower makes specific written
objections thereto within thirty (30) days after the date the statement of
Borrower's Account is sent;

                                  (4) In the event that the aggregate principal
amount of the Revolving Credit Loan outstanding at any one time exceeds the sum
of $12,000,000.00, Borrower shall immediately pay to Lender an amount equal to
or otherwise eliminate such excess;

                                  (5) The provisions of this Paragraph 3B shall
continue in effect until September 22, 2009 and from year to year thereafter,

                                      -6-


Paragraph 3B at any time upon the happening of an Event of Default hereunder.
Upon the effective date of such termination, Borrower shall immediately pay to
Lender the then outstanding aggregate principal amount of the Revolving Credit
Loan, together with interest accrued thereon to the date of payment. No such
termination shall (i) in any way affect or impair the security interest granted
to Lender hereunder or any other rights of Lender under any of the Loan
Documents, arising prior to any such termination or by reason thereof, (ii)
relieve Borrower of any obligation to Lender under any of the Loan Documents, or
otherwise, until all the Obligations are fully paid and performed, or (iii)
affect any right or remedy of Lender under any of the Loan Documents; and

                                  (6) Borrower shall pay to Lender, on the first
(1st) Business Day of each calendar quarter
following the date hereof, commencing January 2, 2007, until the termination
date of the Revolving Credit Loan (as described in Paragraph 3B(5) above) and on
such termination date, a nonrefundable commitment fee for the calendar quarter
(or portion thereof, as appropriate) immediately preceding such payment in an
amount equal to fifteen hundredths of one percent (.15%) per annum (adjusted as
provided below) times the excess, if any, of (i) $12,000,000.00 minus (ii) the
average daily outstanding principal amount of the Revolving Credit Loan plus the
stated amount of any issued and outstanding Letters of Credit during such
calendar quarter (or portion thereof, as appropriate). In the case of the first
payment and last payment hereunder, if the immediately preceding period is less
than a full calendar quarter, the commitment fee as so calculated shall be
prorated by multiplying the same by a fraction, the denominator of which shall
be 91 and the numerator of which shall be the actual number of days elapsed in
such period. The amount of the unused line fee shall be adjusted (increased or
decreased) based upon the ratio of Funded Debt to EBITDA set forth below (and
calculated on a quarterly basis in the same manner as for the LIBOR Rate Margin
and the Prime Rate Margin):

Less than 1.0 to 1.0                                            .25%."



                2.6 Subparagraph I of Paragraph 3 of the Loan Agreement shall be
amended and restated in its entirety to hereafter read as follows:

                         "I. Letter of Credit Facility. Upon Borrower's request
therefor, Lender shall, from time to time so
long as no Event of Default has occurred and is continuing as of such date of
request, issue (i) standby Letters of Credit for the account of Borrower in an
amount of up to $4,000,000.00, and (ii) commercial Letters of Credit in an
amount of up to $2,500,000.00, provided the aggregate amounts available to be
drawn under such standby and commercial Letters of Credit (or actually drawn but

                                      -7-


not yet reimbursed by Borrower), together with the sum of all advances on
account of the Revolving Credit Loan then outstanding, shall not exceed the sum
of $12,000,000.00. Each such Letter of Credit issued by Lender for the account
of Borrower and unreimbursed drafts drawn thereunder shall reduce the amount
available to Borrower on account of the Revolving Credit Loan in an amount equal
to the stated amount of such Letter of Credit so long as such Letter of Credit
is outstanding or such draw unpaid. No Letter of Credit shall be issued by
Lender for the account of Borrower which has an expiration date later than one
(1) year after the termination date of the Revolving Credit Loan described in
Paragraph 3(B)(5) above. Upon payment by Lender under any Letter of Credit, any
amount so paid shall be immediately due and payable by Borrower and Lender shall
have the right to effect payment thereof, together with the payment of any
standard commissions, fees, expenses and charges, immediately by a charge to
Borrower's operating account maintained with Lender. Unless and until such
charge to Borrower's operating account is made by Lender, the unreimbursed
amount of any drawn Letter of Credit shall be considered an advance on account
of the Revolving Credit Loan to satisfy Borrower's reimbursement obligation to
Lender which shall bear interest at the default rate prescribed in Paragraph 3G
above until paid in full by Borrower.

                Lender shall charge Borrower its then-prevailing standard
commissions and fees for the issuance of such Letters of Credit. In the event
that Borrower desires either a standby or a commercial Letter of Credit (subject
to the dollar amount limitations set forth above), the documentation thereof
shall consist of Lender's standard forms therefor and Borrower specifically
acknowledges that (i) the reimbursement obligation of Borrower and any
commission or fee on account of such Letters of Credit shall be included in the
Obligations; and (ii) the occurrence of an Event of Default hereunder shall
constitute a default under the documentation relating to such Letters of Credit
and shall entitle Lender to exercise its rights thereunder with respect to such
default.".

                2.7  Paragraph 3 of the Loan Agreement shall be further amended
to add the following new subparagraph L to the end thereof as follows:

                         "L. Acquisition Guidance Line of Credit Loan.

                         "Lender may, in the exercise of its sole and absolute
discretion, make available to Borrower advances in an
aggregate amount of up to Five Million Dollars ($5,000,000.00) to fund a portion
of the purchase price of future acquisitions by Borrower. The Acquisition
Guidance Line of Credit Loan shall be an uncommitted credit facility, and Lender
shall have no obligation to make any advances to Borrower thereunder. Any
discretionary advances made by Lender to Borrower under the Acquisition Guidance
Line of Credit Loan shall be evidenced by a separate Acquisition Guidance Line
of Credit Note. The terms and conditions (including, without limitation, the
repayment terms and interest rate) for each advance under the Acquisition
Guidance Line of Credit Loan shall be determined by Lender at the time of such
advance. Borrower may hereafter request an advance from Lender under the
Acquisition Guidance Line of Credit Loan and shall furnish to Lender any and all

                                      -8-


information and due diligence materials requested by Lender with respect to such
requested advance and the acquisition to be funded, in part, with the proceeds
of such requested advance. Lender may fund, or elect not to fund, such requested
advance in its sole and absolute discretion. In no event shall advances under
the Acquisition Guidance Line of Credit Loan exceed the aggregate sum of
$5,000,000.00.".

                2.8 On the date hereof, Borrower shall pay to Lender a
non-refundable commitment fee with respect to the Term Loan in the amount of
$14,750.00 and a non-refundable commitment fee with respect to the Revolving
Credit Loan in the amount of $9,000.00, which commitment fees shall be deemed
earned in full by Lender as of the date hereof.

                2.9 Subparagraph (a) of Paragraph 5 of the Loan Agreement shall
be amended and restated in its entirety to hereafter read as follows:

                         "(a) Maintain (i) a Fixed Charge Coverage Ratio of not
less than 1.1 to 1.0, tested at the end of each
fiscal quarter of Borrower for the immediately preceding four (4) fiscal
quarters; (ii) a ratio of Funded Debt to EBITDA of not greater than 2.5 to 1.0,
tested on a quarterly basis at the end of each fiscal quarter of Borrower, (for
purposes of this calculation, EBITDA shall be determined on a rolling four (4)
quarter basis); and (iii) Tangible Net Worth in an amount of not less than
$26,000,000.00, tested at the end of each fiscal quarter of Borrower; each of
the foregoing financial covenants to be determined in accordance with generally
accepted accounting principles consistently applied from year to year and tested
by Lender on a quarterly basis at the end of each fiscal quarter of Borrower
hereafter, commencing with the fiscal quarter ending September 30, 2006;".

                2.10 Exhibits B-II and C-III attached to this Fourth Amendment
shall hereafter be and become Exhibits B-II and C-III to the Loan Agreement

         3. Representations and Warranties of Borrower. To induce Lender to
enter into this Fourth Amendment, Borrower represents and warrants to Lender
that (a) no Event of Default or state of facts which by the passage of time, the
giving of notice, or both, would constitute an Event of Default, has occurred or
is continuing; and (b) as of the effective date hereof, the representations and
warranties of Borrower contained in the Loan Agreement (including, without
limitation, Paragraph 2 thereof) are true and correct in every material respect.

         4. Effect of this Fourth Amendment. Except as modified or amended
hereby, the terms and provisions of the Loan Agreement and the other Loan
Documents shall remain in full force and effect and the obligations, liabilities
and rights of the parties therein and thereunder shall remain unchanged. Nothing
herein shall operate to release Borrower of its obligations under the Loan
Agreement and such other Loan Documents.

         5. Governing Law. This Fourth Amendment is made, executed and delivered
in the State of Connecticut and it is the specific desire and intention of the

                                      -9-


parties that it shall in all respects be construed under the laws of the State
of Connecticut.

         6. Binding Effect. This Fourth Amendment shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns.

         7. Counterparts. This Fourth Amendment may be executed in counterparts,
each of which shall be deemed an original, but which together shall constitute
one and the same instrument.

                IN WITNESS WHEREOF, the parties have hereunto set their hands as
of the day and year first set forth above.

                                                     balance.




The aforesaid payments shall be first applied to accrued interest and then to
principal. Interest charged on the principal sum outstanding hereunder shall be
calculated on the basis of the actual number of days elapsed on the basis of a
360 day year. If this Second Amended and Restated Term Note or any payment
hereunder becomes due on a day which is not a Business Day, the due date of this
Second Amended and Restated Term Note or such payment shall be extended to the
next succeeding Business Day, and such extension of time shall be included in
computing interest and fees in connection with such payment.

         In addition to said principal sum and interest, Maker further promises
to pay, on demand, all reasonable costs and expenses, including, without
limitation, attorneys' fees, incurred by Payee in the collection of this Second
Amended and Restated Term Note.

         This Second Amended and Restated Term Note is issued pursuant to a
certain Loan Agreement dated as of June 28, 2000, as amended effective as of
December 27, 2002, January 3, 2004 and August 1, 2005, and as further amended on
the date hereof (hereinafter referred to as the "Agreement"), by and between
Maker and Payee, a copy of which is on file at the office of Payee at One
Landmark Square, Stamford, Connecticut 06901. The terms of the Agreement are
incorporated into this Second Amended and Restated Term Note by reference, and
reference is hereby made to the Agreement for a more particular statement of
certain representations, warranties, covenants and agreements of Maker and
providing for Events of Default.

         Initially capitalized terms used herein shall have the same meanings
ascribed to them in the Agreement, unless otherwise indicated herein.

         Any prepayment (whether in whole or in part) of this Second Amended and
Restated Term Note prior to the end of any applicable Interest Period may be
subject to a prepayment premium, all as more particularly set forth in the
Agreement. Except for such prepayment premium, this Second Amended and Restated

                                      -14-


Term Note may be prepaid at any time without premium or penalty. Any permitted
partial prepayment shall be accompanied by the amount of accrued interest on the
principal sum being prepaid and shall be applied to the quarterly principal
installments due hereunder in the inverse order of maturity thereof.

         Upon the occurrence and during the continuance of any Event of Default,
or if any payment required to be made on account of this Second Amended and
Restated Term Note shall remain in arrears and unpaid for a period in excess of
ten (10) days after the same shall become due, in which latter event Maker
agrees to pay to Payee the additional sum of five percent (5%) of the amount of
such late payment (other than payments at maturity or after acceleration) to
cover the additional expenses of Payee's handling of such late payment but not
as consideration for making such late payment, and Payee shall be entitled to
demand immediate payment of the outstanding principal balance of this Second
Amended and Restated Term Note and all accrued but unpaid interest hereon, and
the interest rate(s) accruing hereunder shall, from such default, be increased
to a variable rate equal to two percentage points (2%) per annum above the Prime
Rate in effect immediately prior to such default, such rate to change when and
as said Prime Rate changes.

         Maker hereby grants to Payee and any Affiliate of Payee, a lien,
security interest and right of set-off as security for all of Maker's
liabilities hereunder, whether now existing or hereafter arising, upon and
against all of Maker's deposits, credits, collateral and other property now or
hereafter in the possession, custody, safekeeping or control of Payee or any
Affiliate of Payee or in transit to it or any of them, except for any payroll
account, pension or profit sharing balances or similar trust fund accounts or
balances of Maker. At any time, without demand or notice, Payee and its
Affiliates may setoff the same or any part thereof and apply the same or any
part thereof to any of Maker's liabilities hereunder, whether or not matured at
the time of such application and regardless of the adequacy of any other
collateral securing this Second Amended and Restated Term Note. Maker shall be
given prompt notice after the occurrence of any such set-off and application.
ANY AND ALL RIGHTS TO REQUIRE PAYEE TO EXERCISE ITS RIGHTS OR REMEDIES WITH
RESPECT TO ANY COLLATERAL WHICH SECURES THIS SECOND AMENDED AND RESTATED TERM
NOTE, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS,
CREDITS OR OTHER PROPERTY OF MAKER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND
IRREVOCABLY WAIVED.

         No delay or failure of Payee in exercising any right, power or
privilege hereunder or under the Agreement shall affect such right, power or
privilege, nor shall any single or partial exercise preclude any further
exercise thereof or the exercise of any other rights, powers or privileges.

         Payee may at any time pledge all or any portion of its rights under
this Second Amended and Restated Term Note to any of the twelve (12) Federal
Reserve Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C.
Section 341. No such pledge or endorsement thereof shall release the Payee from
its obligations hereunder or under the Agreement.

                                      -15-


         Upon receipt by Maker of an affidavit of an officer of Payee as to the
loss, theft, destruction or mutilation of this Second Amended and Restated Term
Note and upon the cancellation of this Second Amended and Restated Term Note due
to such loss, theft, destruction or mutilation, Maker shall issue, in lieu
thereof, a replacement note to Payee in the same principal amount thereof and
otherwise of like tenor.

         All agreements between Maker and Payee are hereby expressly limited so
that in no contingency or event whatsoever, whether by reason of acceleration of
the maturity of the indebtedness evidenced hereby or otherwise, shall the amount
paid or agreed to be paid to Payee for the use or the forbearance of the
indebtedness evidenced hereby exceed the maximum permissible under applicable
law. As used herein, the term "applicable law" shall mean the law in effect as
of the date hereof; provided, however, that in the event there is a change in
the law which results in a higher permissible rate of interest, then this Second
Amended and Restated Term Note shall be governed by such new law as of its
effective date. In this regard, it is expressly agreed that it is the intent of
Maker and Payee in the execution, delivery and acceptance of this Second Amended
and Restated Term Note to contract in strict compliance with the laws of the
State of Connecticut from time to time in effect. If, under or from any
circumstances whatsoever, fulfillment of any provision hereof or under the
Agreement or the other Loan Documents at the time of performance of such
provision shall be due, shall involve transcending the limit of such validity
prescribed by applicable law, then the obligation to be fulfilled shall
automatically be reduced to the limits of such validity, and if under or from
circumstances whatsoever Payee shall ever receive as interest an amount which
would exceed the highest lawful rate, such amount which would be excessive
interest shall be applied to the reduction of the principal balance evidenced
hereby and not to the payment of interest. This provision shall control every
other provision of all agreements between Maker and Payee.

         MAKER ACKNOWLEDGES THAT THE TRANSACTION OF WHICH THIS SECOND AMENDED
AND RESTATED TERM NOTE IS A PART IS A COMMERCIAL TRANSACTION, AND HEREBY WAIVES
MAKER'S RIGHTS TO: (1) NOTICE AND HEARING UNDER CHAPTER 903a OF THE CONNECTICUT
GENERAL STATUTES, OR AS OTHERWISE ALLOWED BY ANY STATE OR FEDERAL LAW WITH
RESPECT TO ANY PREJUDGMENT REMEDY WHICH PAYEE MAY DESIRE TO USE, AND (2) REQUEST
THAT PAYEE POST A BOND, WITH OR WITHOUT SURETY, TO PROTECT MAKER AGAINST DAMAGES
THAT MAY BE CAUSED BY ANY PREJUDGMENT REMEDY SOUGHT OR OBTAINED BY PAYEE BY
VIRTUE OF ANY DEFAULT OR PROVISION OF THIS SECOND AMENDED AND RESTATED TERM NOTE
OR ANY LOAN DOCUMENT SECURING THIS SECOND AMENDED AND RESTATED TERM NOTE, AND
MAKER FURTHER WAIVES DILIGENCE, DEMAND, PROTEST, NOTICE OF NONPAYMENT OR
PROTEST, NOTICE OF THE ACCEPTANCE OF THIS SECOND AMENDED AND RESTATED TERM NOTE,
NOTICE OF ANY OTHER ACTION TAKEN IN RELIANCE HEREON AND ALL OTHER DEMANDS AND
NOTICES OF ANY DESCRIPTION IN CONNECTION WITH THIS SECOND AMENDED AND RESTATED
TERM NOTE OR THE INDEBTEDNESS EVIDENCED HEREBY.

                                      -16-


         ADDITIONALLY, MAKER HEREBY WAIVES THE RIGHT TO TRIAL BY JURY IN ANY
ACTION, DEFENSE, COUNTERCLAIM, CROSSCLAIM AND/OR ANY FORM OF PROCEEDING BROUGHT
IN CONNECTION WITH THIS SECOND AMENDED AND RESTATED TERM NOTE OR RELATING TO ANY
INDEBTEDNESS EVIDENCED HEREBY.

         MAKER ACKNOWLEDGES THAT IT HAS MADE THE FOREGOING WAIVERS KNOWINGLY AND
VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER CONSIDERATION OF THE RAMIFICATIONS OF
THESE WAIVERS WITH ITS ATTORNEYS. MAKER FURTHER ACKNOWLEDGES THAT PAYEE HAS NOT
AGREED WITH OR REPRESENTED TO MAKER THAT THE FOREGOING WAIVERS WILL NOT BE FULLY
ENFORCED IN ALL INSTANCES.

         THIS SECOND AMENDED AND RESTATED TERM NOTE HAS BEEN MADE, EXECUTED AND
DELIVERED IN THE STATE OF CONNECTICUT AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF CONNECTICUT.
