            (a) The Credit Agreement is amended by deleting the definition of
            Obligations contained in ss.1.1 of the Credit Agreement and
            restating it in its entirety as follows:

                  Obligations. All indebtedness, obligations and liabilities of
            the Borrower and its Subsidiaries to any of the Banks and the
            Co-Agents, individually or collectively, existing on the date of
            this Credit Agreement or arising thereafter, direct or indirect,
            joint or several, absolute or contingent, matured or unmatured,
            liquidated or unliquidated, secured or unsecured, arising by
            contract, operation of law or otherwise, arising or incurred (i)

      (b)   Each reference to "214 Nashua Street, Leominister, Massachusetts
            01453" contained in any of the Existing Documents shall be amended
            by deleting such reference and substituting "680 Mechanic Street,
            Leominister, Massachusetts 01453" therefor;

      (c)   Each reference to "Tigera Group, Inc." contained in any of the
            Existing Documents shall be amended by deleting such reference and
            substituting "Connectivity Technologies, Inc." therefor; and

      (d)   Each reference to "Tigera" contained in any of the Existing
            Documents shall be amended by deleting such reference and

amended by this Amendment, the Existing Documents

shall remain in full force and effect, and each of the Borrower and CTI
reaffirms the continued validity of the Existing Documents as amended on the
date hereof. Each of the Existing Documents and this Amendment shall be read and
construed as a single agreement. All references in each of the Existing
Documents or any related agreement or instrument to the Existing Documents shall
hereafter refer to each of the Existing Documents as amended hereby.

       3. REPRESENTATIONS AND WARRANTIES. Each of the Borrower (with respect to
those made by the Borrower) and CTI (with respect to those made by Tigera Group,
Inc.) represents and warrants that all the representations and warranties as set
forth in each of the Existing Documents are true and correct in all material
respects on and as of the date hereof. All such representations and warranties
are hereby ratified, affirmed and incorporated herein by reference, with the
same force and effect as though set forth herein in their entirety.

       4. DEFINITIONS. Each capitalized term used herein without specific
definition shall have the same meaning herein as in the Credit Agreement.

       5. NO WAIVER. Nothing contained herein shall constitute a waiver of,
impair or otherwise affect any Obligations, any other obligation of the
Borrower, CTI, the other Subordinating Creditors (as defined in the
Subordination Agreement) or the Seller Pledgors (as defined in the Note Pledge
Agreement) or any right of the Co-Agents or any Banks consequent thereon.

       6. COUNTERPARTS. This Amendment may be executed in one or more
counterparts, each of which shall be deemed an original but which together shall
constitute one and the same instrument.

       7. GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS (WITHOUT
REFERENCE TO CONFLICT OF LAWS).

       8. EFFECTIVENESS OF AMENDMENT. This Amendment shall become effective as
of the date hereof upon receipt by the Agent of counterparts of this Amendment
duly executed by each of the Borrower, CTI, the Agent and the Banks and a copy
