November 21, 2001, as amended, by and among Makers (as defined below), the
financial institutions from time to time parties thereto as the Lenders, and
Comerica Bank, as contractual representative for itself and the Lenders (as the
same may be at any time heretofore or hereafter amended, supplemented, or
otherwise modified or restated, the “Agreement”). Initially capitalized terms
used but not defined herein shall have the meanings ascribed thereto in the
Agreement.

          FOR VALUE RECEIVED, NATIONAL TECHNICAL SYSTEMS, INC., a California
corporation, NTS TECHNICAL SYSTEMS, a California corporation, dba National
Technical Systems, XXCAL, INC., a California corporation, APPROVED ENGINEERING
TEST LABORATORIES, INC., a California corporation, ETCR, INC., a California
corporation, PHASE SEVEN LABORATORIES, INC., a California corporation, UNITED
STATES TEST LABORATORY, L.L.C., a Kansas limited liability company, ACTON
ENVIRONMENTAL TESTING CORPORATION, a Massachusetts corporation, and ELLIOTT
LABORATORIES, LLC, a California limited liability company (collectively,
“Makers”), jointly and severally promise to pay to the order of _______________
(“Payee”), on or before the Term Loans C Maturity Date, the principal sum of
________________ Dollars ($___________), or such lesser sum as shall equal the
aggregate outstanding principal amount of the Term Loan C made by Payee to
Makers jointly and severally pursuant to the Agreement (as defined below).

          Makers promise to make principal reduction payments on the outstanding
principal balance hereof in the amounts and on the dates specified in the
Agreement. Makers further promise to pay interest from the date of this Note in
like money on the aggregate outstanding principal amount hereof at the rates and
on the dates provided in the Agreement. All computations of interest shall be in
accordance with the provisions of the Agreement.

          Makers hereby authorize Payee to record in its books and records the
date, type and amount of the Term Loan C, and of each continuation, conversion
and payment of principal made by Makers, and Makers agree that all such
notations shall, in the absence of manifest error, be conclusive as to the
matters so noted; provided, however, any failure by Payee to make such notation
with respect to the Term Loan C or continuation, conversion, or payment thereof
shall not limit or otherwise affect Makers’ obligations under the Agreement or
this Note.

          Upon the occurrence and during the continuance of an Event of Default,
in addition to and not in substitution of any of Agent or Lenders’ other rights
and remedies with respect to such Event of Default, the entire unpaid principal
balance owing hereunder shall bear interest at the applicable Lending Rate plus
three hundred (300) basis points. In addition, interest, Expenses and Fees, and
other amounts due hereunder or under the Agreement not paid when due shall bear
interest at the Prime Lending Rate plus three hundred (300) basis points until
such overdue payment is paid in full.

          If any payment due hereunder, whether for principal, interest, or
otherwise, is not paid on or before the tenth day after the date such payment is
due, in addition to and not in substitution of any of Payee’s other rights and
remedies with respect to such nonpayment, Makers shall pay to Payee, a late
payment fee (“Late Payment Fee”) equal to five percent (5%) of the amount of
such overdue payment. The Late Payment Fee shall be due and payable on the
eleventh day after the due date of the overdue payment with respect thereto.

          Makers shall make all payments hereunder in lawful money of the United

address as Agent may from time to time specify by notice to Makers in accordance
with the terms of the Agreement.

          In no event shall the interest rate and other charges hereunder exceed
the highest rate permissible under any law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto. In the
event that such a court determines that Payee has received interest and other
charges hereunder in excess of the highest rate applicable hereto, such excess
shall be deemed received on account of, and shall automatically be applied to
reduce, the principal balance hereof, and the provisions hereof shall be deemed
amended to provide for the highest permissible rate. If there is no principal
balance outstanding, Payee shall refund to Makers such excess.
