     7.   The Parties hereby acknowledge that, to the extent that
          any provisions contained in the Agreements or other
          agreements of the Parties not specifically mentioned
          herein shall be inconsistent with any provisions
          contained herein, the intent of this Joinder Agreement
          is to provide that the Agreements or other agreements
          be amended to be consistent with this Joinder Agreement
          and that this Joinder Agreement shall control and such
          inconsistent provisions shall be deemed modified by
          this Joinder Agreement. Further each Party agrees to
          provide further assurances that they will execute, upon
          request, any additional document or agreement to give
          effect to the foregoing modifications to the
          Agreements.

     8.   This Joinder Agreement sets forth the entire agreement
          and understanding among the Parties as to the subject
          matter hereof.

     9.   This Joinder Agreement shall not be changed, modified
          or amended except by a writing signed by the party to
          be charged, and this Joinder Agreement may not be
          discharged except by performance in accordance with its
          terms or by a writing signed by the party to which
          performance is to be rendered.

     10.  If any provision of this Joinder Agreement or the
          application of any provision hereof to any person or in
          any circumstances is held invalid, the remainder of
          this Joinder Agreement and the application of such
          provision to other persons or circumstances shall not
          be affected unless the provision held invalid shall
          substantially impair the benefits of the remaining
          portions of this Joinder Agreement.  If any provision
          in this Joinder Agreement is unenforceable or overly
          broad for any reason whatsoever, that provision will be
          appropriately limited and reformed to the maximum
          extent provided by applicable law.

     11.  This Joinder Agreement and any claims arising out of
          this Joinder Agreement shall be governed by and
          construed in accordance with the laws of the State of
          Delaware, without giving effect to the provisions
          thereof relating to conflicts of law.

     12.  This Joinder Agreement and the Agreements represent the
          final agreement between the Parties regarding the
          subject matter herein and therein and may not be

          None


                               -1-

Additional Disclosures
----------------------

          1.   The Company is a party to that Consulting Services
Agreement, dated July 27, 2001 by and between the Company and
ECDI Capital Corp. (the "Consulting Agreement"). Pursuant to the
Consulting Agreement, among other things, ECDI was to assist the
Company in its efforts to effect a "Sale" of the business of the
Company (as "Sale" is defined in the Consulting Agreement") in
exchange for a consulting fee of not less than $250,000 (the
"Consulting Fee").  While ECDI was not successful in its attempts
to effect a Sale of the Company, it is possible that ECDI may
claim that the transactions contemplated by the Note Purchase
Agreement and the Secured Term Note (and all ancillary agreements
thereto) meet the  definition of Sale under the Consulting
Agreement and attempt to collect the Consulting Fee from the
Company.  While the Company's management does not believe the
contemplated transactions constitute a sale under the Consulting
Agreement, it is impossible to determine if EDCI will make such a
claim, and if so whether ECDI would be successful in pressing
such a claim.  Should the Company ultimately be compelled to make
payment of the Consulting Fee, it would likely have a material
adverse impact on its financial position and results of
operation.

          2.   The Company has previously considered, and may in
the future consider, becoming a private company under the
Securities Exchange Act of 1934, as amended. No assurances,
however, can be given that:

     *    such a transaction is feasible;
     *    if feasible, that such a transaction would benefit the
          Company or the Investors;
     *    whether the Company could maintain its net operating
          loss carryforwards after such a transaction.

          To the extent the Company should elect to engage in a
going-private transaction, there would be no public market for
the Conversion Shares thereafter.

          3.   We may need additional working capital after this
transaction to remain operational. No assurances can be given
that the funds received in connection with the contemplated
transactions will be sufficient for any period of time in the
future. To the extent we need additional working capital, we may
not be able to get it on terms acceptable to the Company, or at
all.

          4.   We are in the process of moving our Manchester,
Tennessee operations to Mexicali, Mexico.  The required reduction
in force at our Manchester facility may give rise to certain
litigation which could have a negative impact on our operations.
In addition, the move requires the transfer of a significant
amount of equipment and materials from Manchester to Mexicali.
As the move has not been completed the risks associated with the
completion of the move, including delayed operations due to
damaged equipment, are currently unknown.  Likewise, the level of
performance of the operations at the Mexicali location is
currently unknown.  Losses attributed to the move, disruption in
