LCC hereby represents and warrants to Buyer, Seller and the Senior
Agent as follows:

5.1           Representations
and Warranties of LCC. LCC has
the corporate power and authority to execute and deliver this Agreement and to
perform in accordance herewith; the execution, delivery and performance of this
Agreement (including all instruments of transfer to be delivered pursuant to
this Agreement) by LCC and the consummation of the transactions contemplated hereby
have been duly and validly authorized; this Agreement evidences the valid,
binding and enforceable obligation of LCC except as such enforcement may be
limited by bankruptcy, insolvency, reorganization or other similar laws
affecting the enforcement of creditor’s rights generally and by general
principles of equity (regardless of whether such enforcement is considered in a
proceeding in equity or at law); and all requisite company action has been
taken by LCC to make this Agreement valid and binding upon LCC in accordance
with its terms.

5.2           Transaction Documents. 
True, complete and correct copies of the Transaction Documents have been
previously provided to Buyer by LCC, including the potential adjustments to the
principal amount of the Note set forth in the Note and the Asset Purchase
Agreement, and there are no other material agreements, arrangements, documents
or instruments to which LCC is a party in effect (whether written or oral) that
relate to or otherwise modify the provisions of the Transaction Documents or
affect the Note in any material respect (except for limitations under the rules
of the NASDAQ Stock Market on the amount of stock that is issuable in payment
of interests under the Note).  Based on
LCC’s records, Seller is the only holder of the Note and the only Investor
under the Exhibit A to the Note.  Upon
the execution of this Agreement and the Note Sale Agreement, Buyer will have
all rights of Seller under the Note and the Holder Registration Rights
Agreement, provided, however, that this
provision shall not be deemed to give Buyer any rights under the Asset Purchase
Agreement.

5.3           Status of Note. As of the
date hereof (i) the Principal Balance of the Note is $21,583,651,
(ii) the accrued and unpaid interest on such unpaid principal is $180,007.65
and (iii) no adjustment has occurred to the Principal Balance of the Note prior
to the date hereof.  No
Event of Default (as such term is defined in the Note) has occurred and is
continuing under the Note. LCC has made all payments of the principal and
interest on the Note when due and has not made any prepayment.

SECTION
6   AGREEMENTS OF THE PARTIES

6.1           Consent of the
Senior Agent.  The Senior Agent hereby consents to the
Assignment, the amendment to the Note to the extent necessary to give effect to
the Assignment and to the issuance of the Exchange Note, as defined in Section
6.3 below.

6.2.          Agreements of LCC.  In reliance on the representations,
warranties and agreements of Seller and Buyer herein, LCC hereby,
notwithstanding anything to the contrary in the Note, (i) consents to the
Assignment, (ii) agrees to treat Buyer as the Holder under the Note with all
rights of the Holder thereunder, (iii) agrees to pay Buyer amounts due under
the Note to Silver Point Capital Finance, LLC, Two Greenwich Plaza, First
Floor, Greenwich, CT 06830, Attention: Tim Skoufis, or such other address as
provided by Buyer and (iv) agrees that Buyer shall have all rights of Seller
under the Holder Registration Rights Agreement. 
In consideration of LCC’s agreements hereunder, Seller agrees that the
provisions of Section 3.6 of the Asset Purchase Agreement requiring LCC to
reimburse Seller for the expenses associated with a Carve-Out Audit (as defined
in the Asset Purchase Agreement) are of no further force and effect and Seller
shall pay to LCC any amounts advanced by LCC with respect to these expenses.

6.3.          Exchange of Note.  The parties acknowledge and agree that the
principal amount of the Note may be adjusted pursuant to the terms of the Asset
Purchase Agreement and the Note, except as provided in this Section 6.3. Seller
and LCC agree that (i) as soon as practicable after the date hereof (and in any
event, in no more than 10 Business Days (as defined in the Asset Purchase Agreement)), they will enter into
the Escrow Agreement (as defined in the Asset Purchase Agreement) pursuant to
which Seller will deposit $1,000,000 into escrow to be held and distributed in
accordance with the terms of the Escrow Agreement,  (ii) any decrease in the principal amount of
the Note arising after the date hereof under Article 3 of the Asset Purchase
Agreement will be made by cash payments by Seller to LCC, rather than by
adjusting the principal amount of the Note (provided, however, that if such
amounts are not paid within 10 Business Days of the date that such amounts are
owed, the Note will be adjusted per the terms of  Article 3 of the Asset Purchase Agreement)
and (iii) any increase in the principal amount of the Note arising under
Article 3 of the Asset Purchase Agreement will be made as required thereunder
and shall be reflected in the Exchange Note (as defined below) and  LCC shall have no further obligations to
Seller or Buyer arising out of such adjustment other than its obligations to
Buyer under the Exchange Note. The parties agree that once (i) the actions
described in clause (i) of the preceding sentence have been satisfied and (ii)
as applicable, (x) all amounts that would otherwise decrease the principal
amount of the Note under Article 3 of the Asset Purchase Agreement have been
paid by Seller to LCC or have resulted in adjustments to the Note as provided
for herein or (y) any amounts that would otherwise increase the principal
amount of the Note under Article 3 of the Asset Purchase Agreement have been
finally determined, Buyer will return (i) to Seller for cancellation, the
Promissory Note, dated the date hereof, issued by Seller to Buyer, and (ii) to
LCC for cancellation, the Note and that, in exchange therefor, LCC will issue
to Buyer a new note substantially similar to the Note (in form and substance
reasonably acceptable to the Senior Lenders) (the “Exchange
Note”), except that it will
contain any adjustment provided for herein and will not be subject to further
adjustment. The parties hereto agree to take such actions as are reasonably
necessary to effectuate the actions set forth in this paragraph.
